String matching is an important part in today's computer applications and Aho-Corasick algorithm is one of the main string matching algorithms used to accomplish this. This paper discusses that when can the GPUs be used for string matching applications using the Aho-Corasick algorithm as a benchmark We have to identify the best unit to run our string matching algorithm according to the performance...
Hybrid Renewable Energy System (HRES)s are gradually getting popular for both grid connected and standalone applications as an eco friendly, economical solution. A novel computational tool to model, simulate and optimize grid connected HRESs with V2G is presented in this study. Mathematical model is combined with a simulation algorithm to evaluate energy flows through the system devices and life cycle...
In this paper we present AugLAC, a framework which integrates common features of location aware services, e-commerce and augmented reality into a single infrastructure for the development of location aware mobile applications. The research aim is to generalize the proposed framework to suit different business domains and to allow rapid development of applications using a component based architecture...
Abnormal activity detection plays an important role in many areas such as surveillance, military installations, and sports. Existing abnormal activity detectors mostly rely on motion data obtained over a number of frames to characterize abnormality. However, only motion may not be able to capture all forms of abnormality, in particular, poses that do not amount to motion "outliers". In this...
A superpixel is an image patch which is better aligned with intensity edges than a rectangular patch. Superpixels are perceptually consistent units which carry more information than pixels and adhere well to image boundaries. Nowadays superpixels are widely used for segmentation in computer vision and biomedicai applications. There are many approaches to generate superpixels such as SLIC, QuickShift,...
In this paper a very high gain step up DC-DC converter is proposed. Maximum voltage gain in conventional boost converter like, switched inductor converter, switched capacitor converter, cascaded boost converter etc. are limited due to extreme duty cycle (i.e. duty cycle near to unity). Operation at extreme duty cycle leads to, serious reverse recovery problem at the switches, high conduction losses,...
In this paper we present a framework for rapid object classification that uses multiple views to classify visually similar automotive parts on a conveyor belt. We have constructed a dataset of 25 different manufactured parts consisting of window pillars and guides. These parts vary in size, orientation and luster and are captured from four view points. We are able to achieve a classification rate...
Remote human activity monitoring is critical and essential in physiotherapy with respect to the skyrocketing healthcare expenditure and the fast aging population. One of frequently used method to monitor human activity is wearing inertial sensors since it is low-cost and accurate. However, the measurements of those sensors are able only to estimate the orientation and rotation angles with respect...
In this paper, an algorithm for obtaining load flow solutions for radial systems having generation based on renewable energy have been presented. These renewable distributed generations (DG) in the radial distribution system are modeled as active power and voltage magnitude specified buses (PV) and complex power specified buses (PQ). This method uses an improved backward forward sweep method where...
Microsoft Kinect which has been primarily aimed at the computer gaming industry has been used in bio-kinematic research related implementations. A multi-Kinect system can be useful in exploiting spatial diversity to increase measurement accuracy. One of the main problems in deploying multi-Kinect systems is to estimate the pose, including the position and orientation of each Kinect. In this paper,...
Off grid hybrid renewable energy based power systems for rural electrification has become an attractive solution for areas where grid electricity is not feasible. Hybrid systems use several generation technologies, therefore the selection of proper technologies and optimum sizing of the components has become of great importance in reducing the overall cost and increasing the reliability of the service...
This paper presents an evaluation of microwave Doppler radar in capturing the respiration signal from the chest and abdomen simultaneously using two radar systems. Two experiments were conducted to investigate the feasibility of using Doppler radar in measuring respiration from both chest and abdomen simultaneously. Results obtained indicate that the respiration patterns from the radar were highly...
This paper tackled the problem of establishing a computer brain interface using an Electroencephalography device for the purposes of interfacing with a computer using software developed in house for non-vocal quadriplegics. The hardware used was an Emotiv EEG that was used with a novel interface in order to establish some form of voice communications. The Emotiv headset was then tested using some...
An Application Specific Instruction set Processor (ASIP) is an important component in designing embedded systems. One of the problems in designing an instruction set for such processors is determining the number of registers is needed in the processor that will optimize the computational time and the cost. The performance of a processor may fall short due to register spilling, which is caused by the...
Plagiarism is known as illegal use of others' part of work or whole work as one's own in any field such as art, poetry, literature, cinema, research and other creative forms of study. Plagiarism is one of the important issues in academic and research fields and giving more concern in academic systems. The situation is even worse with the availability of ample resources on the web. This paper focuses...
