Abstract: In this paper we take an opportunity to represent the use of laboratory practices for teachers and students to teach and learn a control design subject. We want to demonstrate use of LabVIEW control design toolkit for teachers and students. Students will find the control design subject easier and interesting by simulating the experimental results, analysing comparisons and the validation of the modelling and controller design. By just changing the parameters in the system equation students will come to know the comparison among different systems and they will visualise the different effects of different systems in one glance. Using this method, the learning-teaching process will become an active one.

Abstract: This work presents a micro device which separates and counts Leukocytes (white blood cell or WBC) from other two type of blood cells, Erythrocytes (red blood cell or RBC), and Thrombocytes (Platelet). The operation is performed using four basic parts, a micro mixer which mixes whole blood and diluent to dilute the blood, a size dependent electrical cell separator which separates WBC from other blood cells , a micro nozzle to increase the flow velocity of cells, a counter unit to count the number of WBC in sample. The size dependent cell sorting is done by electrical pillar arrays. The focusing of incoming cells to the counter is done by focusing electrodes. The main aim of this work is to count the separated white blood cells and it is done by a MEMS basedCoulter counter. Simple structure and ease of operation is the two main features of this device. The design of the device has been done by simulating different unit of the device in ComsolMultiphysics. Simulation results were satisfactory and each unit is able to perform its work as per requirement.

Abstract: This paper presents an advanced three phase inverter topology the Z-Source Inverter and its control using microcontroller 89C52. Z-Source Inverter employs second order filter network at front end which provides unique buck-boost feature for inverter. Z-Source inverter can be controlled by any traditional PWM method. Here the modified maximum constant boost PWM method is utilized for Z-Source inverter control. The microcontroller 89C52 is used to generate PWM pulses and to control operation of Z-Source inverter. The complete hardware is designed to drive the three phase induction motor. The hardware design involves the design of control circuit, driver circuit, Z-Source network, main inverter bridge, power supply etc. The Z-Source inverter is implemented and tested to verify the Z-Source inverter concept. The desired three phase PWM signals are generated by using control circuit and detailed hardware results are presented.

Key words: driver, maximum constant boost, microcontroller, PWM, voltage boost, Z-Source Inverter.

Abstract: This paper describes an investigation to build an Android application that gathers the air pollution information and displays information via a GPRS network. The air pollution data is collected by hardware modules transmitted to Zigbee enabled android device which further transmits to a back-end server to display the pollution map of the place. The application also displays the position of the user. Pollution is the presence in or introduction into the environment of a substance which has harmful or poisonous effects (Oxford University) [1] which certainly requires a careful study before developing any suitable Pollution mapping application. The device will regularly update pollution information and is available anytime. Nevertheless the latest attempts at introducing green technologies for all kinds of machines are starting to be successful thanks to the continuous standardization process that is pondering over the environment prices and making devices more useful for the end user. Even so several important issues are always to be handled strictly before developing and installing an Android Data communication application; factors like USB host, USB accessory, usefulness, robustness and price are critical to determine if the final product will accomplish.

Abstract: Identification based on hand vein pattern is an interesting branch of biometric recognition that is enjoying increasingly attention among the researchers in the recent decade. However, despite the fact the most of the developed commercial systems for this purpose are expensive; their false acceptance ratios are not zero. Therefore, using them for identification purposes can be crucial if they mistakenly accept an imposter (even with a very low probability). The current work proposes a very low-cost hand vein pattern recognition system using a simple modified webcam. The system introduces a blob removal algorithm for enhancing the results of the segmentation and uses a modified version of Hausdorff distance for feature matching for the recognition purposes. Experimental results show that the system can achieve a zero false acceptance ratio while keeping the true acceptance rate in an acceptable level.

Abstract: Economic indicators of electro-dynamic braking have not been properly estimated. Vehicles with alternative power trains are in transitional stage between developments of pollution – free vehicles. According to these aspects the investigation on conventional hybrids drives and their control system is carried out in the paper. The equations that allow evaluating effectiveness of regenerative braking for different variants of hybrid drive are given. Suitable size of ultra-capacitor for efficient energy storage medium in all hybrid electric vehicles has been evaluated. This paper also discuss the advances in double layer electrolytic capacitor technology have opened new areas to complement batteries as a storage medium. Equations for both constant current as well as constant power discharges are discussed. An iterative method for determining the minimum number of ultra-capacitor cells is introduced. The effects of ultra-capacitor sizing on the rating of interface power electronics are examined.

Abstract: The field of electrical engineering is now finding itself being extensively used in vehicular technology. The current demands of high electrical power owing to increase in electrical loads in vehicles and the pressure on automobile makers to reduce emission levels have brought the usage of power converters and electric drives to the frontier. This paper aims to discuss the design and control scheme of an electric drive for vehicular application. The control systems are many; however, the use of vector control has been emphasized. A drive has been proposed and the simulated results show the achievement of speed control. Some light has also been spread on further improvements that can be encapsulated.
