1. ANAHESS, A NEW SECOND ORDER SUM OF EXPONENTIALS FIT ALGORITHM, COMPARED TO THE TIKHONOV REGULARIZATION APPROACH, WITH NMR APPLICATIONS
by Åsmund Ukkelberg, Geir Humborstad Sørland, Eddy Walter Hansen & Hege C. Widerøe
Abstract

The problem of fitting a sum of exponentials to second order data is often called the second order (or two dimensional) inverse Laplace transform (2D-ILT). The present work describes ANAHESS, a new inverse Hessian algorithm which handles this ill-posed numerical problem. The algorithm uses numerical expressions for the gradient and the Hessian matrix, and has performed well on various artificial and experimental data sets. The new algorithm is presented in a Nuclear Magnetic Resonance (NMR) context.

by M.O.Abdullah, P.N.Y.Yek, S.Hamdan, E.Junaidi & P.Kuek

Abstract

The present works describe the design and initial performance study of a prototype airboat for riverine transportation, including mangrove habitat applications, with particular reference to Sarawak, East Malaysia. Many local rural riverine transportation and marine habitat studies are limited due to tide-line dependent and the limitation of conventional blade type marine engine. The use of airboat could ply at the local everglades areas and shallow waters; however the conventional airboat having flat bottom hall may at times not suitable in the narrow mangrove habitat which generally has extended roots. In the present study, our boat was custom designed with Shallow-Vee hall shape, employing a 2-stroke engine. Experimental results have shown that the new airboat built has good performance and balancing capability. Subsequent simulation study employing PROLINE software suggest that 2 passengers as the optimum number for the airboat overall performance (optimum performance and stability), coherent with the experimental trials. Compared with conventional air boats, the new boat design is likely to have two added advantages: (1) relative cheap cost and affordable in development, and (2) shallow-Vee shape design is more suitable then the wider flat bottom shape type due to narrow mangrove habitat, where the shallow mangrove trees generally having roots in the water and extended roots on the water surface.

by Faisal Alkhateeb, Zain Al-Abdeen Al-Fakhry, Eslam Al Maghayreh, Shadi Aljawarneh & Ahmad T.Al-Taani
Abstract

It is assumed that most of organizations have critical positions and rooms and therefore require to be secured and/or monitored. A multi-agent system (MAS) is a system composed of multiple interacting intelligent agents. Multi-agent systems can be used to solve problems which are difficult or impossible for an individual agent or monolithic system to solve. In this paper, we propose a novel system to secure and/or monitor the buildings and faculties of a University campus. The system is based on multi agents and wireless sensors.


4. THE STUDY OF LATERAL TORSIONAL BUCKLING BEHAVIOUR OF BEAM WITH TRAPEZOID WEB STEEL SECTION BY EXPERIMENTAL AND FINITE ELEMENT ANALYSIS
by Fatimah Denan, Mohd Hanim Osman & Sariffuddin Saad
Abstract

Experimental and numerical study on lateral torsional buckling behaviour of steel section with trapezoid web is presented in this paper. Comparison is made with conventional beams with flat web. In the experimental work, sections with nominal dimension 200 x 80 mm and 5 m length were loaded vertically while the lateral deflection were unrestrained to allow for the lateral torsional buckling. In the analytical study, eigen-value buckling analysis in the finite element method was used to determine the critical buckling load. It is concluded that steel beam with trapezoidally corrugated web section have higher resistance to lateral torsional buckling compared to that of section with flat web. The result shows that corrugation thickness influence the resistance to lateral torsional buckling.


5. HYBRID MULTILAYER SCHEMES FOR ACHIEVING THE MAXIMUM POSSIBLE DIVERSITY GAIN
by Nirmalendu Bikas Sinha, P.K.Sutradhar, S.Chakraborty, R.Bera & M.Mitra
Abstract

This paper proposes a novel signal scheme called “Hybrid BLAST STBC approach” this combines MIMO (multiple-input multiple-output) and STBC (space time block code) to generate a system functionally superior to MIMO and STBC systems. This paper compares and investigates the capacity of high data rate wireless local area network systems using MIMO techniques. In particular, two different algorithms-V-Blasts and STBC, are described. A third hybrid approach, which incorporates elements of both V-BLAST and STBC (Hybrid BLAST STBC), is also introduced. The focus of the study is to compare the information capacity of hybrid systems with V-BLAST and STBCs. Hybrid can balance transmit diversity gain and spatial multiplexing gain. All three techniques are compared using both theoretical Shannon capacity analysis and by simulation results for the bit error ratio and capacity performance of the three methods. The result of this study shows that hybrid method attains superior diversity gain performance to V-BLAST and can out form V-blast at spectral efficiencies of practical interest. Furthermore, at low SNRs and low outage probabilities, hybrid is more spectrally efficient. Thus, it is more suitable for low power high data rate wireless applications. Finally, we compare the performance of our proposed system with the conventional scheme by computer simulations which validate the analytical results.

8. EVALUATION OF THE CONTRIBUTORS OF OVERALL EQUIPMENT EFFECTIVENESS USING SHAPLEY VALUE
by Muhamad Arifpin Mansor & Ario Ohsato
Abstract

Maintenance is an indispensable factor in the current manufacturing industries and Overall Equipment Effectiveness is a key performance indicator that provides the overall performance of a single piece of machinery, or for an entire factory. Three measurable components: Performance Rate (PR), Quality Rate (QR) and Availability(A) are working together to achieve an OEE and their combinations in each period are always different. The best tool to evaluate the contribution of these components or contributors is the Shapley value, proposed by Lloyd Shapley. This paper estimates how each component has contributed to OEE at the a decided period, and estimates during which period the activity was best performed using the Shapley value.

by Dr.Vani N.Laturkar
Abstract

There is no denying of the reality that globalization will persuade the companies, almost in all the hues, to progressively embark on global operations. This paper discusses the worth of increasing the pervasiveness of multi-cultures in organizations as a way of facilitating varied advantageous developments in cultural progression. The paper portrays the vision of happy and enduring combination of Western Management techniques with practices of Eastern management. The combination can result in value – based holistic approach with specific reference to Indian Management in the new millennium. Recent research on psychological flexibility related to multi-cultural management suggests that helping people to accept, but not believe, their unpleasant thoughts and feelings contributes to people becoming more caring. This paper reviews this aspect also by assuming that cross cultural interactions being positive as well as negative, make the subject more challenging and interesting. The examples in the succeeding paragraphs will further signify the importance of the concept.
