Since many years sustainability is becoming a challenging issue in software engineering domain. However till now, no clear nor exhaustive characterization was proposed to the concept of "sustainable software". Without it, sustainability remains an intangible ideal for software systems and consequently can't be assessed nor controlled nor enhanced. To cover this gap, we propose a Generic...
In this paper, we proposes a GSM based non-invasive wearable physiological parameters monitoring system. The system can be used to monitor parameters such as temperature and heart rate of a human subject. This system is worn on the waist by an at-risk person. The person is monitored using several sensors and data is sent wirelessly. The device detects if a person is medically distressed and sends...
The document reader reads the data from text document image for optical character recognition. If the image is rotated, it will not work properly. Some document images have a few degree of skew angle which creates difficulties in many other applications, so it is necessary to find out the skew angle of the digitalized document. This paper proposed an algorithm to automatically determine the skew angle...
Image and video processing applications tend to be real time constraints. Applications like visual surveillance, traffic monitoring, vehicle tracking, autonomous navigation, computer vision etc. has the basic requirement of identifying moving object in real time. Hardware based approaches are well suited for real time motion detection as they results in high performance and low cost. For rapid development...
With the advent memristor and the development of cross bar architecture using it, has led to an influx in the development of programmable analog circuits. Prior to this, the arbitrary waveform generation was based on a memory driven system, where the data values to be read out at any particular instant of time was stored in the system memory. Thus, the maximum operating frequency of such a system...
In Medio-Lateral Oblique (MLO) view of mammogram, the presence of pectoral muscle may sometimes affect the detection of architectural distortion due to their similar characteristics with abnormal tissues. As a result pectoral muscle should be handled separately while detecting the breast cancer. The straight line approximation of pectoral muscle is also very important in obtaining the breast tissue...
Image segmentation is a process of dividing the image into a set of multiple pixels.The aim of segmentation is to change the representation of an image that is more meaningful and easier to analyze. For this reason color image segmentation is essential for an image. On the basis of two parameters i.e. threshold selection and seed point selection associated with segmentation method. In this paper we...
Video Copy Detection focuses on preventing illicit use of digital videos. Video copies are generated by applying different sorts of transformations on the original video content. To detect such transformed copies, the extraction of a transformation invariant feature descriptor is a requisite. Among the various existing transformations, flipping is the recently employed copy attacks. Hence, we propose...
Super-resolution is an algorithm, which is capable of producing a high resolution output image with low resolution input image. This paper present a novel approach for producing high quality-high resolution image, which contain NE-based learning and fast edge filtered image reconstruction based on slope-limiter function. By using this approach, the produced high-resolution image maintain discontinuity...
In this paper, the additional flexibility in designing antenna arrays by employing time-modulation (TM) technique have been exploited to synthesize phase-differentiated dual beam patterns with low dynamic range ratio (DRR) of static excitation amplitude. An optimization technique based on differential evolution (DE) is utilized to find out a common set of static amplitude and switch-on time (SOT)...
In software project development, once implementation completes, the next phase deals with the generation of application binaries from source files. This process of generating binaries is termed as software build. Generating the binaries takes away a lot of productive time if the project is huge. However, if the generation of project binaries is performed on a distributed system, the time taken for...
In this work, we explore the possibility of applying an Ensemble square root filter (EnSRF) for tracking mobile stations in multi-path wireless networks. The EnSRF applied here is a variant of the Ensemble Kalman filter, that makesuse of the Kalman update formulas within a Monte Carlosetup for estimating the unknown state (position) of the mobile stations. Multipath propagation environments encountered...
With the advent of large scale computing environment, there is a need for scheduling methods which allow multiple DAG-structured applications to share the cluster resources with the objectives of increasing the throughput and maximizing the resource utilization. The number of processors allotted to each application is decided during runtime, depending on the number and nature of applications being...
The web mining is a cutting edge technology, which includes information gathering and classification of information over web. This paper puts forth the concepts of document pre-processing, which is achieved by extraction of keywords from the documents fetched from the web, processing it and generating a term-document matrix, TF-IDF and the different approaches of TF-IDF (term frequency Inverse document...
Cognitive Radio (CR) is a novel promising approach proposed to ensure efficient spectrum utilization. It is the obvious solution to the spectral congestion problem. Spectrum sensing is the most essential functionality required for the practical implementation of cognitive radio networks. An efficient spectrum sensing method must detect very weak primary user signals while being sufficiently fast and...
We consider a cooperative relay communication system where the source and the relay have separate frequency bands for message transmission. The relay is assumed to be a decode-forward node, i.e. It can decode the information send from the source node and re-transmit after suitable modifications. With power splitting at the source, we find an optimum relaying function which achieves the capacity of...
Multicarrier Modulation has attracted a lot of attention in the modern communication world to satisfy the need for higher bit rate. The most popular MCM technique, OFDM has low efficiency due to the insertion of cyclic prefix and the use of IFFT in OFDM leads to poor stopband behaviour for OFDM prototype filter which leads to spectral leakage among the subchannels. Due to the disadvantages of OFDM,...
