It is well-known that an artificial agent exhibits deterministic dynamics when it moves in a closed real world environment. It is interesting to determine this dynamics when a real biological being such as fish is kept in a real closed environment and free to move in it. This paper determines some deterministic dynamics of fish motion freely moving in a closed environment. The task is divided into...
This paper presents the numerical simulations of wire type dual band loaded Inverted-L antenna for 3.35GHz mobile WiMAX and 5.5 GHz Wi-Fi operation. The outcome of work is a dual band loaded ILA designed with two separate bandwidth-(3300–3450) MHz and (5450–5550) MHz. Total area occupied by the antenna is 23 mm × 27 mm. The main intention of this research is to propose a multiband loaded ILA for multi-serving...
In the coming of era the digitized image is an important challenge to deal with the storage and transmission requirements of enormous data, including medical images. Compression is one of the indispensable techniques to solve this problem. In this paper, we propose an algorithm for medical image compression based on lifting base wavelet transform coupled with SPIHT (Set Partition in Hierarchical Trees)...
Computer vision and pattern recognition systems play an important role in our lives by means of automated face detection, face and gesture recognition, and estimation of gender and age. This paper presents a face detection and gender identification task of discriminating between images of faces of men and women from face images under non-uniform background. This is done by detecting the human face...
Mobile users can move between the different wireless networks because several heterogeneous wireless networks are deployed and can be used in a small area. So there need vertical handover issues in an effective manner. This paper proposed two vertical handover scheme based on fuzzy interference system and subtracting clustering method in a heterogeneous environment and simulates to verify performance...
Enhancing conversion efficiency is the main object in the photovoltaic technology of solar cells. III-V semiconductors, InGaN alloy are very encouraging candidates for solar cells. In recent years, InGaN alloy provides the ability to tune the band gap for solar energy conversion. In this work, InGaN based QW and QD solar cells have been theoretically studied and evaluated the performance with various...
Autonomous navigation is an important feature that allows a mobile robot to independently move from a point to another without an intervention from a human operator. Autonomous navigation within an unknown area requires the robot to explore, localize and map its surroundings. By solving a maze, the pertaining algorithms and behaviour of the robot can be studied and improved upon. This paper describes...
Frequency deviations and inter-area tie-power fluctuations from their respective scheduled values following a local load disturbance which is a source of great concern in interconnected power system operation and control. In this paper, two methods are proposed to minimize such deviations and thereby enhancing the performance of Automatic Generation Control (AGC) of an interconnected power system...
Non invasive and continuous measurement of blood pressure becomes popular now a day. This is very effective way for hypertensive patients to prevent cardiovascular problems and precisely regulate anti-hypertension cures. Blood pressure can be measured by conventional cuff-based sphygmomanometer or invasive instruments in non continuous mode. In this paper, we propose the microcontroller based continuous...
This paper focuses on the automatic tracking of a moving object. The motion of living beings such as human beings, cats, dogs, fishes or any other substances like star, earth, and airplane can be tracked by this system. A tracking algorithm is developed in order to analyse the motion of object is chaotic or not. Automatic tracking of object is done by several stages. These are image capturing, image...
Electronic energy meter is capable of taking readings and can store it into its memory. Taking energy meter reading is time consuming and an expensive task. The meter reader travels for a long distance and take the reading manually to prepare the bill. Consumers have to go to the billing office, stand in a long line and submit the bill. This is a boring job and time consuming also. It can be avoided...
This paper represents the microcontroller based modified sine wave (MSW) generator for power inverter which is connected to the PV (Photovoltaic) system. The advantage of this inverter is the use of a low cost microcontroller that generates MSW having low harmonics and voltage regulation is fully controlled by microcontroller only which is approximately zero. It can also vary the frequency of inverter...
Non invasive continuous blood pressure measurement system is more useful than conventional blood pressure measurement systems. The arterial system is extraordinarily well regulated blood delivery network in human body. It responds very quickly according to the body movements like altered body position, or in sudden excitation. So now a day's continuous blood pressure monitoring devices are becoming...
