This paper describes an ENERGY CONSERVATION & MONITORING SYSTEM, designed to avoid usage of extra energy consumption and monitor the usage of energy. Energy crises have caused economic halts to many countries, causing hindrance in development of developing nations. This project is a small effort to solve this problem. The testing and demonstration of this project was conducted in Faculty of Engineering Sciences and Technology, Hamdard University, Karachi, Pakistan. In first stage of the project, load calculation was done in which load of whole campus was determined. After that, implementation of this project was done in defined area. In which motion sensors were used to detect the presence of body in a certain range. The appliances were controlled by motion sensor in that area and this was logged in software connected with computer through serial port. The simulation results show that after implementation of this project around 20- 30 % energy was saved.

Analysis of the tiny retinal vasculatures in retinal fundus images becomes difficult due to very low and varied contrast between the retinal vasculature and the background. Fundus fluorescein angiogram overcomes these problems and provides an excellent visualization of the retinal vasculature; however it is an invasive procedure requiring injection of contrasting agents. Further investigation of the RETICA method, a non-invasive method of image enhancement developed earlier, is reported in this paper. It was found that noise is present in the Retinex image. Thus, the identification of the noise in the Retinex image and its removal has been the focus of this research paper. The method used to identify noise is based on adaptive wiener filters (additive, multiplicative, and additive plus multiplicative filters) and the fundus model image and real fundus images are applied to these filters. It is observed that retinal fundus images contained both additive and multiplicative noise. The noise is reduced by using adaptive wiener filter (additive plus multiplicative adaptive wiener filter) based method which resulted in 2.84db an improvement in PSNR.

Intermittent measurement is defined as a situation where a mobile robot experiences loss of measurement data during observation due to sensor failure or imperfection of the system. The impact of intermittent measurement on the Simultaneous Localization and Mapping (SLAM) of a mobile robot is the subject of this paper. The analysis is important since SLAM requires recursive measurement data update throughout the process. In this paper, the effect of intermittent measurement on the state error covariance matrix was analyzed on two basic conditions, which are when the mobile robot is stationary and when it is in motion. We have observed the impact on the determinant of covariance matrix. It is proven by our analysis that intermittent measurement could cause inaccurate estimation of robot's position and might increase the state error covariance matrix.

Interpretation of Ground Penetrating Radar (GPR) dataset towards detecting underground utility is a challenging task. The underground utility information such as location, depth and type serves as a reference prior to any construction project in order to avoid damage to the utility during excavation. However, the interpretation of GPR images is a tedious and timely process which requires human intervention. This study proposed a new hyperbola fitting technique to estimate the radius of buried utility (pipes and cables). The method was applied to nine (9) different sizes of buried pipes for radius estimation purposes. The result indicates that the technique is capable of estimating the radius of buried pipes with acceptable result; approximately 97.7% to 99.2% for cable/pipe type with a radius between 45mm to 150mm are detected accurately.

The purpose of this paper is to explore the ability of the system identification technique in detecting a specific gas at a constant concentration level by a single sensor. Metal oxide semiconductor (MOS) gas sensor is used due to its wide range of applicability in gas monitoring systems. Using the Batch computer method, 115 outputs were recorded with sampling time of 0.57 Sec at a concentration level of 2600 (ppm) for Methanol, Ethanol, and Betanol gases. Applying the estimated model, each gas was successfully distinguished.

Web technology is currently used in all daily activities and is considered a backbone of life. The amount of information continuously increases and grows, specifically that of unstructured information that has no rules or constraints. Such information is difficult to handle and thus requires organization and management before it can be useful. Information extraction techniques are efficient methods of converting unstructured documents into structured data. Attempts have been made to extract structured information that can be used with small amounts of textual data. However, for large amounts of data such as those found in the World Wide Web, the amount of extracted information is huge, and the relationships between extracted information are difficult to determine. Studies that focus on managing extracted information are few. In this paper, we present an overview of the recent studies on managing unstructured information, information extraction and managing extracted information. Managing extracted data using our proposed model for the rapid extraction and clustering of unstructured data for back-end applications in low-level of relational database systems is highlighted. This paper is intended for researchers interested in information extraction management and its applications.

Hand hygiene (HH) compliance is known as the most significant factor to reduce the transmission of infection to patients in health care institutions. Thus, monitoring hand hygiene compliance has become an important tool to control the infection transmission. Most of the currently used HH monitoring devices and systems use battery powered badges or wristbands to control users. In this study, a user friendly, passive RF-ID based electronic system with monitoring capabilities was introduced. The system includes a wearable, passive RF-ID wristband, wall mounted dispenser and a software to measure the HH compliance rate. The technology laying behind the HH station is introduced and the advantages and drawbacks of the system is discussed.

This paper presents a proposed design of a leg rehabilitation system. The system will be implemented on a reconfigurable wheelchair prototype in order to provide additional two rotational degrees of freedom (DOF) for serving more rehabilitation purposes. Lagrangian dynamic formulation is used to derive the system dynamics. Joints frictions based on Coulomb friction model are considered in the leg rehabilitation system. The system equations of motion are linearized since the model is dealt with in state space representation. LQR control approach is considered and derived for stabilization of the system. Simulation Results validating the model and the control approach are presented and discussed.

Genetic Algorithms (GAs) is proven to be effective in solving many optimization tasks. GAs is one of the optimization tools used widely in solving problems based on natural selection and genetics. This paper is intended to cover the study of GA and parallel GA and analyses its usage in CPU and GPU. One of the popular ways to speed up the processing time was by running them as parallel. The idea of parallel GAs may refer to an algorithm that works by dividing large problem into smaller tasks. Broad literature review in this paper includes a categorization of the GA operations that involved with some theories and techniques used in GA, presented with the aid of diagrams. This review attempts to study and analyse the behaviour of GA and parallel GA categories to work in GPU depending on the type of genetic algorithm. Parallel GA for GPU covers the architecture of Compute Unified Device Architecture (CUDA).
