This paper is a consequence of a main project, the project is a novel experiment which provides “live” traffic ticket issuing and registration. One of the main police requirements is information systems to provide information for police anywhere and anytime. We made some efforts to improve police performance with new solution. Advanced of civilian wireless network infrastructure made the mobile devices increasingly popular. Mobile equipments are widely used for communication but lacking of security makes it unsuitable for transmitting the confidential data. In this paper, we discuss requirements of the traffic police data center firstly, and then this paper is produce a generally applicable queuing model that abstracts all Traffic Police Data Center components, in a queuing model of a Traffic Police Data Center, the customers are officers, the servers are located on Traffic Police Data Center (TPDC) and queues are populated by traffic tickets that wait for the services. Finally, we focus on the resources monitoring.

This paper presents the implementation of March-based algorithm as proposed in [1] into an Memory Built-in Self-Test (MBIST) data and read/write controller. The design uses the7 approach of Finite S täte M achine (FSM)-based a rchitecture which is more plausible since the design was part of the engine that will be exclusively developed for the testing of this algorithm alone. This controller will represent a portion of MBIST engine that can be incorporated together with other portions to build a complete MBIST engine.

This work focuses on the realization of convolutional encoder and adaptive Viterbi decoder (AVD) with a constraint length, K of 3 and a code rate (k/n) of 1/2 using field-programmable gate array (FPGA) technology. This paper presents a 4-state, radix-2, hard decision AVD which has the ability to decode adaptively through different traceback length (TL). The performance of the implemented AVD is analyzed by using ISE 9.2 and MATLAB simulations. The AVD is targeted to a Xilinx XCV300PQ240–4 FPGA device for hardware realization. The decoder parameter TL can be reconfigured via the implementation of AVD, in accordance with the changing channel noise characteristics of the threshold signal-to-noise ratio (SNR), which is 6 dB. The synthesis results show that the reconfiguration parameter TL of 4 and 15 of AVD implementation has significant difference (>20% improvement) in FPGA device utilization. The results also show that the use of reconfiguration leads to a 28% area occupancy of slice usage improvement over a TL of 15 model compared to a TL of 4 model with tolerable loss of decode accuracy, in accordance with the bit error rate (BER) for real-time voice and video.

The paper discusses the effect of wing size on magnetic levitation using coil induced field for a proposed Levitator Guide (LG). The levitation consists of two main parts namely permanent magnet and current carrying copper coils. The variation of these parts may effects the produced levitated force. A few models have been analyzed with simulation. Results indicated that levitator guide model of wings with centered elbow give rise to the desired performance. Finally, a new type of levitator guide is proposed and fabricated.

The study of systems involving fluid flow, heat transfer and associated phenomena using computers is termed as computational fluid dynamics (CFD). The governing equations that define fluid flow phenomena are solved for specific problems using CFD codes. CFD codes comprise three main elements which are preprocessor, solver and postprocessor. The main concern of this research is the solver element. The solver uses information from the preprocessing stage to approximate unknown flow variables by means of functions, discretize governing flow equations and solving the equations. Unstructured meshes are preferred for solving complex geometry problems. Boundedness of the discretization technique is ensured by using High Resolution (HR) scheme which has its roots in Normalized Variable Formulation (NVF). Turbulent flows present new issues such as intermittency, separation and recirculation. These are some phenomena which must be accounted for in extending the current 3D solver to handle turbulent flows. The research methodology involves literature review on CFD equations and turbulent flow theories, numerical discretization and advanced programming techniques. A review of existing 3D code and test runs are necessary to understand the structure of the source code and incorporate extensions. The output from the solver can then be analysed using Techplot 360 which is a postprocessor.

Hybrid implementation of DACs using a combination of thermometer coded DACs together with binary weighted DACs to achieve high conversion performance have been reported. This work compares and analyzes between 12-bit and 14-bit DACs. It is found that the speed depends on the segmentation configuration where simpler segmentation results in higher conversion speeds. The power dissipation is also dependent on the simplicity of segmentation where simpler segmentation also results in lower power consumption.

This paper presents design of proportional-integral-derivative fuzzy logic controller (PIDFLC) to control the position in AC motor. Fuzzy logic controller has been designed using VHDL language for implementation in field programmable gate array (FPGA). Two version of the controller have been designed, the first one is 6-bits which uses 6-bits for each input/output variables (6FBC), while the second uses 8-bits for each input/output variables (8FBC). Second order mathematical model represents a position control in AC motor has been used in unity feedback control system with the proposed controller. Simulation environments have been built using non-synthesizable VHDL code for the purpose of simulation in ModelSim, and the same design is coded in Matlab for the purpose of simulation in Matlab (MSBC). The Mean differences between MSBC and 6FBC for Step response and control action are −0.0256 and −0.0009 respectively, and The Mean differences between MSBC and 8FBC for Step response and control action are −0.0030 and 0.0021 respectively, since the 8FBC is superior to 6FBC and its much close to MSBC.

Research and de velopment on gas sensors design and fabrication demands the needs for test chambers as the characterizing and testing of gas sensor are based on its detection of the concentration of different type of gas under the influence of temperature and also humidity. This project, a Fully Temperature Controlled Test Chamber is about the design and development of a system to provide an artificial environment for gas sensor characterization. Th e main part of the designed system is th e temperature feed back loop control system. Its function is to monitor and regulate the environment temperature to the desired value for characterization of gas sensor under test. While the LM35DZ temperature sensor is used for this purpose, the in tended chamber system to be designed is ab le to communicate with control switches from outside of the chambers using keypad and LCD. The user can set the desired temperature in the chamber, and then the PIC16F877A microcontroller which acts the “brain” of this system will analyze and process the input signal from the sensor and key pad to give th e corresponding output to control th e h eater and display on the LCD s creen. When the steady state condition has been reached, the chamber will be ready for the testing of gas sensors under test. The inlet valve, vacuum pump and fan integrated in the chamber are also fully controlled b y the microcontroller. Beside, th e control system can also be controlled manually by using the manual switches. When tested using the sensor under test, the test chamber and the regulation system of the temperature are working successfully as programmed and give the desired outputs.

The technological world has attained a new dimension with the advent of miniaturization and a major breakthrough has evolved in the form of moems, technically more advanced than mems. This breakthrough has paved way for the scientists to research and conceive their innovation. This paper presents a mathematical analysis of the wave propagation along the non-uniform waveguide with refractive index varying along the z axis implemented on the cantilever beam of MZI based moem accelerometer. Secondly the studies on the wave bends with minimum power loss focusing on two main aspects of bend angle and curvature angle is also presented.
