Ibnu Sina Institute for Fundamental Science Studies (IIS)
The forerunners of IIS produce research of leading quality and international acclaim; directly applying basic knowledge of physics, chemistry and biology with mathematics to facilitate the advancement of local technology, engineering and material discoveries and pursue fundamental scientific advances through interdisciplinary programs and collaborations.
The research undertaken by IIS will provide the education and training of researches preparing to meet the scientific challenges of the future, in tandem with the Malaysian goal of having world class scientists; ultimately equivalent to Nobel Laureates.
IIS encourages and embraces cooperative and interdisciplinary research among the scientists. IIS strives to be leading scientific research laboratory in the region where new knowledge in fundamental science will be discovered.
It is a pleasure to present IIS Annual Report 2003. This time last year the Annual Report 2002 was written in a borrowed office in the Science Faculty. Now we are blessed to be able to operate in our own Institute; a building strategically located at the highest location in UTM. Our objective remains to promote research in fundamental sciences which are beneficial to mankind.
The coming year will mark the intensification of IIS’s effort into a full scientific research campaign that is required to support the country’s vision of securing a knowledge based society and economy for the medium and longer term. Generally in IIS, there will be a gradual development of the scientific laboratories equipped with state-of-the-art research instruments that we hope to be the centerpiece of our campaign. This exciting project will drive equally ambitious objectives to secure our goal of becoming a renowned scientific research centre which offers the best possible facilities and environment to scientists. Our intention in building is to enhance the quality of research and encourage meeting of multidisciplinary scientific minds.
Over the last twelve months, the enjoyment of being in IIS and the sense of excitement of being part of the scientific management has grown tremendously as I get to become more involved in the life and work of the Institute. After three years being the Director of IIS, I am even more inspired by the loyalty and commitment received from all quarters. It has been a continuing source of deep satisfaction to find the Institute a cheerful place, conducive and continually freshened by the enthusiasm and vigour of our members.
2003 has been a busy and satisfactory year for us. Despite the delay in the completion of the long awaited building, we managed to achieve all endeavours that we set with commendable success. I believe that we have taken some important strides in the last year to strengthen and establish our ability, as a research institute, to fulfil the responsibility we are given by our status ‘to promote fundamental science research’. We have established specific scientific areas as our prioritised research activities which are advanced materials, nanotechnology, theoretical physics and mathematics. Laboratories were set up and facilities acquired in order to facilitate the implementation of the research activities. Within our means, we have organised numerous scientific activities, from which the Annual Fundamental Science Seminar 2003, Excellent Scientist Program and Creativity Workshop were the most successful.
It is evident from the response that IIS is becoming a national and international entity. Our effort in promoting the Institute has been successful. Last year we received many visitors; many of whom are internationally known scientists. Our own scientists have benefited from their visits through research collaborations, exchange of ideas and scientific talks. Our networking capabilities have really proven that research institute like IIS can bring up the name and standard of our community to greater heights. At the same time, a new building will greatly enhance our ability to attract conference business and offers more exciting opportunities in the future.
In common with other scientific communities, we face tremendous pressure on our finances, autonomy and academic independence. There is no doubt that higher level of funding are essential if we are to achieve a position of a world-class research institute. In these circumstances, we must look for other means of funding and research grants. We need to step up our efforts to attract more research activities by intensifying our programmes and reaching out.
We offer further report on the progress of the research efforts, scientific activities and achievements for 2003. I would like to extend my gratitude to everyone who has supported our endeavours; without their support, financial and moral, we could achieve but little. The last year has seen a marked and welcomed increase in the number of researchers taking advantage of our facilities. We like to think IIS has played its part in encouraging the sense of belonging and establishing contacts. The responses to our newsletters have been warm.
In our determination to make IIS the special place to do research, and to reinforce the value of discovering knowledge both for its own sake and for the benefit of society at large, continuous affection from the scientific community, global networks and support from the university are required. Finally I would like to acknowledge all researchers who have been part of our community. For now, let me just say that your involvement is crucial to our ability to extend to future generations the experiences and the opportunities that we ourselves have had the privileged to enjoy.

Current Research Focus
Nanophysics, Optoelectronic Devices and System (ODS), Nuclear Physics
Nanophysics is the study of low-dimensional systems within the nanoscale regions, around 10-9 nm. The research covers nanosample fabrication of many materials, studies on the physical properties, which includes the effect of preparation parameters to the characteristic of nanosample. Work includes the development of a novel nanodevice, Single Electron Transistor (SET). This is a top down research programme under the Intensified Research on Priorities Areas (IRPA) and it is headed by Prof. Dr. Samsudi bin Sakrani.
There are six projects under this program and the details are given below:
1. The Growth of Gallium Arsenide Quantum Dots (QD) using MOVPE and Their Development for Single-Electron Transistors: Quantum dots of various sizes and doping level will be grown based on our proposed design. Setting up of doping levels, layer thickness and chamber temperature is very important and a part of our major studies. The growth normally involves formation of heterostructure layers such as GaAs buffer layer, followed by n+-GaAs channel layer and GaAs cap layer. To obtain optimum parameters for growth, the system needs calibration. Furthermore, it is very important to set accurate doping level which corresponds to the charge carrier in the channel layer. Before any growth could be done, it is important to design and model the QDs. A computer simulation is used to study the characteristic of the dots based on the proposed design. Researchers: Prof. Dr. Samsudi Sakrani, Prof. Dr. Rashdi Shah Ahmad, Assoc. Prof. Dr. Zulkafli Othman, Assoc. Prof. Hideki Hasegawa, Assoc. Prof. Dr. Razali Ismail, Dr. Hazri Bakhtiar, Dr. Mohd. Nor Yusof, Muhammad Zaki Yaacob, and Dr. Abdul Fatah Awang Mat.
2. The Synthesis and Growth of Silicon Quantum Dots using VHF-PECVD for Single-Electron Transistors: Plasma-enhanced chemical vapor deposition (PECVD) is employed for the growth of silicon quantum dot, preferentially in upgrading the compatible plasma. Conventional radio-frequency generated plasma (13.6 MHz) is just sufficiently enough for the dissociation of silane gas in reactor chamber, and one can expect to produce different nanostructures if the degree of plasma is considerably changed. Experimental depositions conditions such as the gas flow rates, catalyst, doping, and deposition geometry are studied. These will ensure the optimum growth of the samples with the specific and required novel properties. Modification to the existing PECVD system is the key point to the quantum dot’s growth and formation. The results will be supported by both theoretical and experimental evident. Silicon depositions will be attempted at different setting parameters until optimum experimental conditions are identified. These include optimum doping levels required for the SETs fabrication.

Prof. Dr. Uda Hashim, Dr. Sabar Derita Hutagalung, Dr. Yarub Al-Douri Muhammad Zaki Yaacob, and Rosnita Muhammad.
3. The Structural and Optical Characteristic Studies of Quantum Nanostructures for Single-Electron Transistors (SETs) Materials: The research is to study the structure, such as the surface morphology in depth of quantum nanostructures (quantum dots, quantum wires and carbon nanowires) suitable for SETs using Scanning Electron Microscope (SEM), and Scanning Tunneling Microscope (STM). The nature bonding of QD/QW can be analysed using Fourier Transform Infrared Spectroscopy (FTIR). This technique measures the absorption of various infrared light wavelengths by the material of interest. The optical properties of quantum nanostructures suitable for SETs are also studied using Photoluminescence (PL) spectroscopy to obtain information about energy band structure, type of transition, and conduction phenomena in QD/QW. The result will be compared and feed to the theoretical consideration. Researchers: Prof. Dr. Samsudi Sakrani, Assoc. Prof. Dr. Yussof Wahab, Assoc. Prof. Dr. Karim Deraman, Assoc. Prof. Dr Mohd Khairi Saidin, Dr. Mohd. Nor Yusof, Dr. Hazri Bahtiar, and Rosnita Muhammad.
4. The Development of Electron Transport Analysis Techniques in the Quantum Dots/Wires: The research involves the designing and developing the electrical properties measurement techniques to characterize the QDs/QWs, including electron transport measurements, single-electron capacitance spectroscopy and ballistic electron emission microscopy. The fundamental characteristics in transport through QDs/QWs such as Coulomb blockade, Kondo effect, electronic energy levels, accumulation of mobile charges, and transport through buried heterostructures and metal-semiconductor interfaces for SETs applications are also studied. Researchers: Dr. Sabar Derita Hutagalung, Dr. Sutapa Roy Ramanan, Assoc. Prof. Dr. Rizal Astrawinata, Assoc. Prof. Dr. Zulkafli Othaman, Dr. Yaacob Mat Daud, and Mohammad Nuzaihan Md Nor.
5. The Modeling and Simulation of Quantum Nanostructures for Single Electron Transistors: To study theories related to quantum nanostructures (QD/QW) and to develop models for SET configuration using a computer simulation. Developing of modeling include the modification of any known and published modeling, extend the used ones and apply to new materials and devices. The works also involve theoretical study of the physical, optical, electronic, electrical, thermal properties and devices fabrication. Researchers: Prof. Dr. Karsono Ahmad Dasuki, Assoc. Prof. Dr. Tahir Ahmad, Assoc. Prof. Dr. Razali Ismail, Dr. Johari Adnan, and Mohd Khalid Kasmin.

These will include a fibre Bragg grating fabrication unit, a fibre coupler machine, a source-fibre coupling machine and a fibre bundling machine. The aim of the exercise is to obtain a desired product from each machine, but its importance lies in the fundamental study during the process of fabrication. Thus, the research is geared towards an end product, but is fundamental in nature. Researchers: Assoc. Prof. Dr. Rosly Abdul Rahman, Assoc. Prof. Sabirin Hj Ikhsan, Assoc. Prof. Dr Jalil Ali, Mr Rahim Omar and YM Raja Kamarulzaman.

• IIS-MINT Contract Research
The nuclear science laboratory of IIS and the Malaysian Institute of Nuclear Technology (MINT), are joined together in a contract research. Under the two years agreement, the nuclear science laboratory is used to analyse food and water samples provided by MINT for the content of alpha and beta radiations. Analysis is done on water samples provided by MINT to determine the level of alpha and beta radiation using the Low Background Counting System Model, LB5500. More than 100 samples from approximately 40 companies and government agencies have been analysed. High readings were observed in samples provided by 6 companies. Future work will concentrate on water samples taken from various water authorities in the country. IIS is one of the three institutes in the country, which has such facility. Later, it is expected that the analysis will be extended to the determination of low gamma radiation using the Ge(Li) spectrometer setup available in the laboratory. Initially, the quantum of the contract is based on the number of samples analysed. On the intellectual property, it is mutually agreed that IIS and MINT will have the joint ownership of any papers published. Researcher: Prof. Dr. Noorddin Ibrahim.

The use of Hyperpure Germanium (Li) detector to estimate the gamma radiation dose received by the public from natural occurring radioactive materials (NORM), or that may due to nuclear contamination from nuclear testing. Current work by the undergraduate students involves marine sand samples taken from the coastal beach of the Peninsular. Researcher: Prof. Dr. Noorddin Ibrahim.
Studies of hydrogenated amorphous carbon thin films synthesized by DC-PECVD method (2000-present)
Leader : Prof. Dr. Samsudi Sakrani
Support : Research facilities purchased under IDB
Researchers : Assoc. Prof. Dr. Bakar Ismail, Assoc. Prof. Dr. Mohd. Khairi Saidin, Putut Marwoto and Suriani Abu Bakar
Research is on hydrogenated amorphous carbon (a-C:H) thin films which were prepared using a dc-PECVD method. The effect of various experimental conditions (pressure 0.2-0.4 Torr, room temperature, a fixed CH4 flow rate and Ar flow rates between) were studied. Analysis were made using FTIR Spectroscopy. It was observed that, from the transmission measurements, the valley-like curves shape changes with decreasing pressure, with the presence of absorption characteristics at 0.2 torr. The corresponding sp3 –C-Hn modes were between 2873 and 2961 cm-1, and the main infrared absorption rate in a-C:H was observed to occur at 2958 cm-1, revealing the presence of sp3 CH3 bond detectable at pressure of 0.2 torr. Photoluminescence characterizations were also carried out on these samples to support the IR experimental results. Optical measurements were carried out using a UV spectrophotometer and the resulting spectra indicated transparent behaviour with absorption coefficient greater than 104 cm-1 over the visible light region. Further analysis gave values of optical parameters which were comparable to those obtained by different researchers.

Corrosion Monitoring or Detection using Flux-Gate Gradiometer
Leader : Assoc. Prof. Dr. Rashdi Shah Ahmad
Grant : IRPA VOT 72218 (RM 208,050.00)
Researchers : Assoc. Prof. Dr. Rashdi Shah Ahmad, Dr. Amiruddin Shaari, Dr. Johari Adnan, and Dr. Yaacob Mat Daud.
The objective of the research is to be able to monitor the ongoing corrosion process in metal. The basic principle of the detection system is to measure the magnetic flux density generated by the corrosion current. Unfortunately the magnetic flux density resulting from the corrosion process is very small (i.e. much smaller than the earth magnetic field which range from 30 to 60 mT). Simple magnetometer will not be able to detect this small changes in flux density. However, a gradiometer with suitable length of base line should be able to detect the flux density changes provided the field has very large spatial gradient. Our design of fluxgate gradiometer consists of two identical fluxgate magnetometers (also designed by our group), separated by an optimum base line. The output of each magnetometer are processed by independent processing unit and finally differentiated. In earth magnetic, adding small dc offset voltage to one of its input terminal can zero the output of the differentiator. The advantages of the detection system are that it does not required direct physical contact with the sample. Therefore it can be used to detect corrosion in metal insulated by thermal insulator or protective coating without having to remove them. However the thickness of the insulator or coating permissible will depend on the sensitivity of each magnetometer.
Result: (i) Successfully developed fluxgate magnetometer systems and has developed fluxgate gradiometer system based on our magnetometer systems.
(ii) Successfully detected the changes in magnetic field generated by corrosion.
(iii) Two MSc and four undergraduate students had involved in this project and graduated.
Investigating of the structure, properties and Application of phosphate based Glasses
Leader : Assoc. Prof. Dr. Rosli Hussin
Grant : IRPA VOT 72153 (RM 245,000)
Researchers : Prof. Dr. Md. Rahim Sahar, Assoc. Prof. Dr. Rosli Hussin, and Zuhairi Ibrahim
Our research is to characterize and quantify atomic structural distributions in glasses with NMR. The non-crystalline structure of a glass limits the amount of useful bonding information that can be obtained by diffraction techniques, particularly from multi-component compositions that possess overlapping pair distribution functions. As a consequence, a variety of spectroscopic tools, each perhaps sensitive to a different aspect of the local structure must be utilized to obtain sufficient structural information to relate the composition of a glass to its macroscopic properties. Phosphate glasses are often characterized by low glass transition temperatures and large thermal expansion coefficients, and have been developed for a variety of applications. Such physical properties are a direct consequence of the phosphate tetrahedral network nature that constitutes the glass structure. In simple alkali and alkaline earth phosphate glasses, increasing the concentration of the modifying oxides will convert the network from a highly cross-linked ultraphosphate [O/P<3.0], to chain-like metaphosphate [O/P=3.0], to very depolymerized pyro- [O/P=3.5] and orthophosphate [O/P=4.0] structures. The number and nature of bridging POP bonds between neighboring P-tetrahedra, thus determine the properties of the ultra phosphate compositions, whereas the properties of the highly modified compositions are sensitive to the P-anion distributions and the nature of the non-bridging oxygen bonds to the modifying cation. Quantitative structural information about both the P-tetrahedral distributions and the numbers of bridging and nonbridging oxygens that constitute these networks can be obtained by a variety of spectroscopic probes, including 31P solid state nuclear magnetic resonance (NMR), Raman and X-ray photoelectron spectroscopy’s, and chromatography. These studies will be reviewed and the information used to describe the compositional dependencies of phosphate network structures and glass properties.
Result: (i) One MSc student completed the project.
(ii) Two on-going PhD students.

Post-Laboratory Production of Amorphous Silica and Synthetic Zeolites from Rice Husk
Worm type MCM-41 synthesized from rice husk
Rice husk ash contains more than 97% silica. When rice husk is burnt under controlled conditions, the resulting ash is usually in crystalline form. Although thermal treatment of rice husk is the most economical source of silica, the challenges are to obtain a carbon-free ash while maintaining its amorphous structure. This project involves the combustion of rice husk in a small-scale fluidized bed testing rig and by plug flow converter. An amorphous silica containing carbon < 0,2% has been successfully obtained by combustion in fluidized bed rig and plug flow converter. Researchers: Prof. Dr. Halimaton Hamdan, Assoc. Prof. Dr. Mohd.

Silica aerogel from rice husk
3-dimensional network of silica aerogel
Silica aerogel has been directly prepared from an organic waste product; rice husk. Aerogel is a novel nanomaterials, environmentally friendly Space-Age Super Material. A common feature of all aerogels and nanofoams are their open, ultra small inter-connected pores with a size of <100 nm (0.100 nm). This open cell structure provides access to the entire surface area for reaction/deposition of materials as either gas or ions in solution. The physical properties of aerogels are controlled by the density and microstructure of the gel. Silica aerogels are generally known for being an extremely lightweight transparent solid (down to <0.05 g/cm3 with excellent thermal insulating properties, high temperature stability, very low dielectric constant, and extremely high surface area. Some initial applications have included atomic particle detectors and super insulation for aerospace applications and they were used to insulate the Mars rover.

This project involves the tailoring of zeolite-based catalysts for selected organic syntheses namely Friedel Crafts alkylation and acylation for the aromatic ketone fine chemicals with anti-oxidant property, aldol condensation for dual functional group fine chemicals, and alkenes oxidation towards the production of diol with chiral properties. Zeolites with different pore systems will be synthesized and modified in order to tailor the properties such as acidic, basic or bifunctional oxidative acid catalysts for those organic processes. Prelimenary testing has shown highly active catalysts with more than 60% product selectivity.

Zeolite as Natural Gas Adsorbents
This study addresses some fundamental aspects of natural gas adsorption and its relation to zeolite physicochemical structures in order to get better understanding, and hence, to engineer those structures to enhance the adsorption of methane by zeolite in term of the adsorption capacity and selectivity especially at high pressures and temperatures. It has been found that SiO2/Al2O3 ratios, crystallization time, and temperature effect on zeolite physicochemical properties and gas adsorption characteristics. Methane adsorption behavior at low pressure differs than nitrogen, which this might be due to difference in polarity of both gasses. Researchers: Assoc.

This project attempts to develop a new composite ion-exchanger with high durability and resistance to adverse conditions in the control of pollution by trace and heavy metals, toxic elements, POPs and radioactive materials brought about by the discharge of domestic and industrial wastes into the water. The zeolites will be modified into its organo- and inorganic functionalities, characterized for their ion-exchange capacities, robust structural stability, morphological and other adsorption properties before a comprehensive system is fabricated from these newly developed materials with nano-properties for use in water purification processes. A prototype filter system is expected to be produced at the end of this study which can be used in normal households for clean water production. Researchers: Prof. Dr. Alias Mohd Yusof, Dr. Md.

The Development of Polymer Nanocomposites for Electronic Devices
Polymer nanocomposites represent the current trend in developing novel nanostructured materials. At nanoscale, a conductive polymer could be intercalated into a layered host to prepare nanocomposite materials with good electronic conductivity, magnetisation or luminescence. In year 2000, processable polyaniline/TiO2 nanocomposite with 1 - 10 S/cm conductivity and polyaniline-intercalated graphite oxide nanocomposite with conductivity of 0.52 S/cm have been successfully synthesised. This research project is into the preparative and development of polymer nanocomposites, based on polyaniline, polypyrroles, poly (phenylenevinylene), or polythiophene, with electrical conductivity, electrochromic, or electro-luminescent properties.

Development and Application of New Modified Poly (styrene-divinylbenzene) Adsorbents and Chromatography Stationary Phases
Poly (styrene-divinylbenzene) (PS-DVB) is an excellent material for chromatography and sample preparation with its high stability over the pH range 1-13. However, the high hydrophobicity of the PS-DVB matrix itself is a serious limitation to its suitability in the reversed-phase mode for the ore polar molecule separations such as biochemicals which are mostly performed in aqueous media. This project aims to synthesise PS-DVB phases and further modify the phase by introducing moieties that will increase the dispersive forces and lower the hydrophobicityof PS-DVB to as nearly as those for silica-basedpacking materials. The effects of the PS-DVB copolymerisation conditions have been investigated including the type of stirrer, time of reaction, surfactants, and stabilizer. Poly (vinyl alcohol)-Modified PS-DVB adsorbents and PS-DVB-clad zirconia will also be studied and the physical and chemical properties as well as the applications of the modified PS-DVB adsorbents will be examined.

Grant : RMC VOT 71863 (RM 20,000)
Researchers : Assoc Prof Dr Nor Haniza Sarmin, Assoc Prof Dr Abdullah Tahir Othman, Fong Wan Heng, Mohd Sham Mohamad.
Group Theory is one of the most powerful mathematical tools used in Quantum Chemistry and Spectroscopy. It allows the user to predict, interpret, rationalize, and often simplify complex theory and data. One of the most important types of groups is the one which consists of all the symmetry operations pertaining to a molecular structure. In chemistry, the symmetry elements and symmetry operations are inextricably related. Symmetry can be present in the form of coefficients of equations as well as in the physical arrangement of objects. In this theoretical work, we propose the general properties of groups to aid in correctly and systematically determining the symmetry operations of water molecule (H2O). Another objective of the research is to determine the molecular vibrations of H2O via group theory. The rational and theorems in group theory can be used to reduce costs and labour in quantum mechanical calculations.
Minimum Counterexamples in Group Theory.
Grant : RMC VOT 71966 (RM 20,000)
Researchers : Assoc Prof Dr Nor Haniza Sarmin, Sheila a/p Ilangovan.
Group Theory is a branch in mathematics. The main study of mathematics is proving theorems. In mathematics, experimentation might lead to a conjecture, which may or may not be correct. If even one example can be found for which the conjecture is not true, then it is not a theorem. In fact, the standard way to show that a conjecture is not a theorem is to provide such a counterexample. In this research we will be using the minimum counterexample technique to refute fifteen given conjectures. If there is a counterexample to a given theorem, then there is a counterexample G of smallest possible order. This research will begin with some basic concepts in Group Theory that include types of groups of small orders (1 through 12). The study will deal with groups given by generators and defining relations, or with groups given by their permutation representations since every group has its own properties or definition and is in different order. This research will also use standard notation for generators and relations of a group. The search for minimum counterexamples gives the student an excellent opportunity of becoming familiar with the groups of small order.
Mathematical Modelling of the Recombination Capacity of System of Enzymes Acting on DNA.

Splicing systems were originally developed as a mathematical or dry model of the generative capacity of DNA molecules in the presence of appropriate enzymes. A splicing system consists of a finite initial set of strings over an alphabet, and a finite set of rules by which the strings can be spliced together to form new strings in addition to the initial strings. This theory relates formal language theory to the study of informational macromolecules. The mathematical formalism that will be used is the splicing system concept (also called H-system concept) was introduced. The formal definition was kept very close to biochemistry being modelled. A vast expansion of splicing theory has occurred in an extensive literature. The research we proposed here is related to the exciting new science of DNA-Computing that burst on the international research scene with the ‘wet-lab’ solution of a mathematical problem familiar in graph theory. Many of the splicing system investigations were done to provide a theoretical basis for DNA computing. Wet-lab DNA solutions of mathematical problems have been carried out using the enzymatic behaviours proposed for investigation here. The objective of this research is to determine set of features of enzyme systems that many natural systems of enzymes have in common. Besides that, the research will be done to find the generative capacities of sets of enzymes systems, to define special classes of splicing systems, to develop algorithms for special classes of splicing systems derived from the examination of sets of enzyme sites and to produce software applicable in the molecular sciences. Mutually advantageous interaction between the research proposed here and DNA computing is anticipated.

Researchers : Assoc Prof Dr Nor Haniza Sarmin, Hasmawi Yusof.
Group Theory is a branch of mathematics in the field of pure algebra. Galois developed it about 160 years ago, where he used the term of group to form a closed set. Mathematicians beginning from early 19th century then expanded the concepts of group theory, and later after that, in the years of 1920’s and 1930’s, this theory was applied to atoms and molecules were used widely in the field of chemistry. This report only focuses on the application of group theory in chemistry, specifically on the vibration of ammonia’s molecule. Various concepts of group theory will be described to help in understanding the applications of this theory in molecular vibrations. Since the research about molecular structure involves the concept of symmetry, group theory is the best formal method to describe the symmetry concept more systematically. This report also describes the elements of symmetry in an ammonia molecule, and the symmetry operations involved to form a group. The main focus in this report is to learn about vibrations of ammonia molecule, including the method to determine the number of molecular vibration modes and then look the type of its mode vibration using the group representation’s theory.

Applied and computational complex analysis is the study of computational aspects and applications of complex analysis to solve problems related to science and engineering. The goals are to present complex analysis as a tool for modelling phenomenon of the physical world, and as a source of algorithms for the efficient use of these models. The following two areas are studied on both theoretical and numerical aspects:
a. Conformal Mapping: An important method of complex analysis and familiar tool of science and engineering is conformal mapping. In various applied problems, by means of conformal maps, problems for certain “physical regions” are transplanted into problems on some standardized “model regions” where they can be solved easily. By transplanting back we obtain the solutions of the original problems in the physical regions. This process is used, for example, in solving problems related to fluid flow, electrostatics, heat, mechanics and aerodynamics. In this research, we study the integral equation technique for effective numerical conformal mapping. Researchers: Assoc Prof Dr Ali Hassan Mohamed Murid, Baharudin Hurmin.
b. The Riemann Problem: The Riemann problem is a complex boundary value problem which has an application in hydrodynamics. This research considers the integral equation approach for solving numerically the Riemann problem.

• Feynman Integral and Completely Integrable Systems.
Grant : RMC VOT 75086 (RM 20,000)
Researchers : Assoc Prof Dr Zainal Abdul Aziz, Assoc Prof Dr Nor Haniza Sarmin.
The passage from classical mechanics to quantum mechanics is called quantization. The relation between these two theories is studied by Drinfield (1987) and Witten (1987) from different points of view. According to Drinfeld, in both cases, observable forms an associative algebra that is commutative in the classical case and noncommutative in the quantum case. The algebraic approach leads Drinfeld to the notion of quantum groups. We wish to show this to be connected exactly to the notion of complete integrability of certain suitable system. Witten’s approach is topological whereby quantization is described in terms of states using Feynman’s path integral method. This approach leads Witten to string theory. Our programme intend to show the existence of an exact connection between Drinfeld’s work (notion of complete integrable system) and Witten’s work (notion of Feynman integral and related methods), presumably via Jones Polynomials and associated braid groups. This is an important open problem in modern mathematical physics.
Computational Fluid Dynamics & Nonlinear Waves (CFD & NLW)
• Mathematical Models for Low Gravity Fluid Flows and Heat Transfer in Micropolar Fluids
Grant : IRPA VOT 74046 (RM 79 000)
Researchers : Assoc. Prof. Dr Norsarahaida S. Amin, Dr Maslan Osman, Sharidan Shafie.
Micropolar fluids physically represent fluids consisting of randomly oriented particles suspended in a viscous medium. The suspended particles can be bar-like, sphere-like, or small rigid cylindrical elements similar to large dumbbell-shaped molecules. Examples include polymeric fluids, fluids containing certain additives such as liquid crystals and colloidal suspensions, and naturally occurring fluids like animal blood. The local structure and micromotions of the fluid elements give rise to microscopic effects, whereby the existing classical Navier-Stokes theory is inadequate to describe. Many classical flows are being re-examined to determine the effects of these microstructures. The presence of dirt in mechanical instruments or the presence of dust and smoke particles in a gas may be modelled using micropolar fluid dynamics.
• Mathematical Modelling of Surface Waves
Grant : IRPA VOT 72359 (RM 35 150)
Researchers : Assoc. Prof. Dr Zainal Abdul Aziz, Assoc. Prof. Dr Norsarahaida S. Amin.
A direct method is proposed for obtaining travelling-wave solutions of non-linear wave equations that are essentially of a localized nature. It is based on the fact that most solutions are functions of a hyperbolic tangent. This technique is straightforward to use and only minimal algebra is needed to find these solutions. Nine examples of applications in surface waves models with detailed work out have been carried out. There are the Burgers equation, the Korteweg-de Vries equation, the modified Korteweg-de Vries equation, the Fisher equation, the non-linear reaction-diffusion equation, the Gardner equation, regularised long wave equation, the Boussinesq equation and the modified Volterra's equations. The effectiveness of this method on the sine-Gordon equation and the non-linear Schroedinger equation are also discussed.
Modelling of surface waves over flat and uneven bottoms are carried out, using wave group formulations. This formulation of relevant approximate models of surface waves such as the Korteweg-de Vries (KdV) and KdV-type models resulted in the derivation of non-linear Schroedinger (NLS) equation and NLS-type equation. These represented improved models of surface waves over flat and uneven bottoms. Analytical and numerical solutions of these improved models are generated.
Converging ideas from surface wave models and optical models are developed and proposed for future plans e.g. optical gratings and water waves gratings techniques. As a result, we proposed a mathematical model to describe the amplitude decrease of a surface wave running over a series of depressions in the bottom profile, simulating the effect of an idealized shoreline where all the incident wave energy is consumed by breaking. This idea of water wave gratings motivated a practical notion of artificially constructing submerged bars to protect a beach from incident waves.
Mathematical and Statistical Modelling and Optimisation (MaSMO)
• Optimization of Nonlinear Dynamical Systems
Grant : RMC VOT 71910 (RM 17,000)
Researchers : Assoc Prof Dr Mohd Ismail Abd Aziz, Rohanin Ahmad, Assoc Prof Nazeeruddin Yaacob.
The aim of the project is to develop and implement algorithms for optimization of dynamical systems for application in complex communications, process control, robotics and other control applications. It is based on novel computational procedures have jointly been developed by Roberts (City University, London), Mohd Ismail (UTM) and Becerra (Surrey University) which is called Dynamic Integration System Optimization and Parameter Estimation algorithms. These algorithms incorporate model-reality differences in its iterative computations of optimal control of nonlinear uncertain systems. The algorithms have been successfully applied in certain engineering processes in manufacturing. The algorithm have been further developed and extended to interconnected dynamical processes by Mohd Ismail.
In order to implement such algorithms in more complex industrial applications such as robotics arm and dynamic inventory management further exploratory research on implementations issues such as parameters fine-tuning, convergence and stability are needed. The updating mechanism of this algorithm is of the gradient descent type. The gradient descent method is one of the most fundamental procedures for minimizing functions of several variables. It works well during the early stages of the optimization process. However, the performance of the method is poor when nearing the optimum point due to small orthogonal steps taken causing the zigzagging phenomena.
The DISOPE algorithm is an iterative procedure, in which the updating mechanism plays an important role in its termination (convergence). In order to aid with the speed of convergence momentum terms from the neural networks was added to updating mechanism, with promising results. Results on improvements to speed up the convergence using the parallel tangent (Partan) method and momentum terms have been published. More results on the convergence limit profiles of both improved algorithms and their complexicity analysis will soon be published.
Applied Computations and Numerical Simulations (ACANS)
• Multiprocessor Models for Task Scheduling and VLSI Design Problems
The work consists of four main problems of study. First, we look at the stochastic task-scheduling problem using the reconfigurable mesh network as the computing platform. Through our model called the Dynamic Simulator on Reconfigurable Mesh (DSRM) which maps a randomly generated number of tasks onto the processors at discrete time, some reasonably good load balancing results were obtained. The second problem is the application of the first model in the edge detection problem using the Laplacian convolution method on the same parallel computing network. In the third problem, we extend the scope to include a strategy for the single-row routing of pins and vias in VLSI design, using our model called the Enhanced Simulated annealing for Single-row Routing (ESSR). This model is the parallel implementation of the simulated annealing method, and it generates optimum solutions to the problem. The fourth problem is the extension of the single-row routing problem, where a model has been developed to transform a complete graph into its single-row representation. This last problem has some significant contributions in applications such as scheduling and channel assignment problem in cellular telephone systems.

Ferroelectrics (FE) are advanced materials and have a lot of technological applications. The applications are possible because FE materials have useful dielectric properties. They have very high relative dielectric permittivity, and exhibit very fast rate of switching in the order of nanoseconds. In addition to these, FE materials are transparent to the far infrared (FIR) and therefore they are useful materials to be used in the terahertz technologies. However, the effect of size usually limits these useful properties especially in switching. Here, the dynamics of FE under the influence of size effect is presented to understand the switching behaviour of the material. FIR spectroscopy is also proposed as a tool to probe into the size effect. When intensity of an incident infrared beam is high (in the excess of 1012 W/m2), the response of FE material to the beam becomes nonlinear. Many applications of NL optics have become practical for technological uses. There is a continuing need to find nonlinear (NL) optical materials with large NL coefficients and fast response, and FE materials have long been demonstrated to be the candidate materials. A formalism to derive nonlinear optical susceptibility coefficients for bulk FE in the lower temperature phase is introduced and some of the coefficients are numerically estimated. The calculated coefficient for second-harmonic generation (SHG) is used to study the transmission of the nonlinear effect from a FE Fabry-Perot cavity. The calculated SHG transmission signal is presented and discussed. Another interesting behaviour of the optical properties of bulk FE is in the vicinity of the so-called morphotropic phase boundary (MPB). Near this boundary, the linear and thus nonlinear susceptibility coefficients of FE are expected to diverge. The MPB is introduced here and how the interesting effect can be exploited for technological applications is discussed.
Update on Asia Pacific Nanotechnology R & D and
Lerwen Liu, PhD, President of nABACUS Partners Ltd Japan
1 August 2003
The Asia Pacific (AP) region is advancing to becoming the most ambitious and dynamic Nanotechnology region the world. There have been significant changes in the Science and Technology policy making in AP countries since the announcement of the US National Nanotechnology Initiative (NNI) in Jan. 2000. Governments in the AP region started to plan and have placed Nanotechnology as one of the priority areas in S & T planning. The budget for Nano-science and Technology R & D has been increased substantially and more strategically allocated. The total public spending in the AP region is about US$1.4b for 2003 (70% of which is from Japan, assuming 100 yen equals 1US$) and private investments are in the rise. The appreciation of the importance of Nanotechnology R & D has been growing in various industries and businesses in the region. The commercialization of the Micro- and Nanotechnology has become a key focus in government and corporate R & D strategy particularly in advanced countries such as Japan. MEMS foundries are being established across Asian countries including Japan, Korea and Taiwan. Nanotechnology in particular is the buzzword in Science & Technology policy making all over Asia. In most Asian countries, the definition of Nanotechnology includes MEMS. Dr Lerwen Liu will provide the latest update on the Nanotechnology government funding and industry strategy in the Asia Pacific region including Australia, China, Hong Kong, Korea, Japan, Singapore, Taiwan and other ASEAN countries The corporate and venture capital investment interests in this region will also be outlined. Highlights in the Nanotechnology developments in the region including Bionanotechnology, Nanoelectronics and Nanomaterials will be presented. The total public spending in the Asia Pacific region is expected to exceed USD1.4b for. This indicates the commitment from the governments in AP region to take a significant role in the global Nanotechnology development, and the appreciation of the importance of Nanotechnology R & D and its impact in industries and businesses in the region. Unlike the European Union, the AP region has no government or an organization to coordinate the regional Nanotechnology policy, education, network, industry and business development. There is an increasing awareness of the necessity of building strong alliance across in the AP region in Nanotechnology R & D and commercialization. Dr Liu will outline a proposal for the Asia Nanoforum, a platform for a regional and global cooperation in Nanotechnology.
Optical Signal Processing
Dr. Ahmed Muhammed AlManasreh, Hashemite University, Jordan.
6 August, 2003
The optical signal processing (OSP) field has been broadening over the recent years due to the vast number of applications light waves encompass. OSP tools are essential in understanding the phenomena as well as in tailoring characteristics of devices and systems to desired applications. The field includes the characterization, analysis and synthesis of its domain of interest.
In this seminar, we present recent advances in state of the art technologies that have been enabled through OSP tools and techniques. First, we consider the inverse problem of Fiber Bragg Gratings (FBGs) by which the grating spatial distribution is computed from a desired application – specific spectrum. Common methods of synthesizing FBGs will be discussed and attention will be given to the extremely powerful differential methods. Fiber optic sensing has been a very active area of research for over a decade now. We look at some of the read out techniques processing FBG based sensors. In the efforts of making all optical networking a realty, optical code division multiple access was proposed. We survey some of the recent advances in this field based on superstructure FBGs. It is believed now that fiber optic networking has to be integrated with cellular networks to unleash the full potential of the later. We look at the recent advances in the Radio over fiber networks. Finally, a proposal is presented to establish interdisciplinary research at UTM in the fields presented in this seminar.
The Physics Behind The Gaussian Elimination Procedure
Dr. Frederidcus Petrus Henricus Van Beckum, University Of Twente, Netherland
28 August 2003
Numerical calculation of physical or engineering problems of ten involves linear system of equations in matrix-vector form E.g. for one-dimensional heat conduction, the system is tri-diagonal and Gaussian elimination (the well known technique we all learned in first gear’s classes) is an effective way of solving. It consists of two “sweeps” the elimination sweep and the back-substitution, and then the solution is at hand. Though this way of solving seems to be a purely numerical algorithm, it must have a physical meaning: physical information (about boundary conditions and heat sources) is communicated all over the domain. And clearly very efficiently: after one sweep down and one up things are settled exactly. In this talk I will analyse what precisely this efficient physical message is, as a by-product we find an unusual mathematical formula for solving a second order boundary value problem.
