This paper deals with the designing an interface between AXI Protocol based system and DDR3 Memory. It enables an AXI host to read and write data in a DDR3 Memory. It has been designed to utilize the DDR3 interface for maximum throughput. It implements FIFO where it stores the write command and writes data and passes it to DDR3 Memory. Similarly, it collects data from DDR3 Memory and stores in a FIFO...
The paper will describe various types of security issues which include confidentiality, integrity and availability of data. There exists various threats to security issues traffic analysis, snooping, spoofing, denial of service attack etc. This paper focuses on symmetric and asymmetric cryptography. A new model is proposed RES(Requirement Encryption Standard) which combines various security parameters...
The exponential growth and proliferation of the MOOC platform in recent years has facilitated easy access to advanced learning materials in the form of video lectures across almost all major specializations. The ever expanding outreach of internet has further boosted the utility and attraction of this medium of learning across the globe. Handheld devices like i-pad and e-notebooks can be used to access...
This paper presents the use of Quartic and Quintic order finite elements for computing cutoff wavenumbers of arbitrary shaped waveguides. These finite elements are used for mapping the boundaries of waveguides with the highest accuracy. In the case of waveguides with curve geometries, the mapping is done by quartic and quintic order parabolic arcs. The domain of a particular waveguide is transformed...
Classification of imbalance data is the major challenge to the community these days. Machine learning algorithms can evolve a one-sided classifier when data is imbalance. The vital challenge in imbalance dataset problem is that sometimes the minority (tiny) classes are more useful, but standard classifiers tend to be biased toward the majority (huge) classes and ignore the tiny ones. In this paper...
Nowadays, digital image forgery detection is one of the most challenging tasks. In this paper, a new block-based method is proposed to detect tampered region in copy-move forgery case. In the method, feature vectors are extracted using DCT transform from non-overlapping blocks of the image. Then, these vectors are lexicographically sorted. Copied blocks are selected from identical vectors based on...
In engineering technique, to push the intelligent transportation system into our daily life, the dedicated short range communication(DSRC) is used. DSRC is a protocol which is used for one or two way medium range communication. To reach the dc-balance and enhancing signal reliability the FM0/Manchester encode must adopts the DSRC standards. The code diversity between FM0 and Manchester encoding seriously...
This paper proposed a new system for image based authentication, where the image is treaded as identification of authenticated user. This system employs approach to store a unique id or password into image and helps to restrict unauthorized user access system. This proposed algorithm is help to eliminate the weakness of password authentication and bypass the risk generated from password authentication...
Music is a source of recreation from past and people are listening to music to refresh their mind and have enjoyment. In recent years we have seen there is lots of research on music signal which is related whether music really creates emotion in human mind. Some raga are restful or restless natures though it make be sung by same artist. In this paper we focus main on study of Raga which is restful...
This paper presents the results of investigations in speech emotion recognition (SER) in English and Hindi based on micro perturbations in pitch, called jitter, as well as very small variations in intensity, called shimmer. Jitter and shimmer are proposed as minimal, reliable and effective features for speech emotion recognition since it is difficult to bring about such minute variations in intensity...
Acoustic Radiation Force Impulse (ARFI) imaging is a type of ultrasound elastography used in medicine, particularly for the monitoring and diagnosis of cancers. Medical professionals observe the tissue elasticity of the ARFI equipment for the diagnosis of the cancer. This paper investigates the role of image processing on the ARFI image for the diagnosis of breast tumour. Initially, in the pre-processing...
Rheumatoid arthritis is a chronic inflammatory disease. It occurs mostly in joints such as wrist, foot and knee. Other than joints it also affects other parts in the body. Inflammation around the heart region and low red blood cell count are also possible causes of this disease. Although different imaging modalities like X-ray, MRI and CT are used to diagnose this disease. In recent days thermal imaging...
In video compression, one needs a highly efficient motion estimation algorithm in terms of processing speed. A novel block matching algorithm for motion estimation in a video frame sequence well suited for a high performance VLSI implementation is presented in this project. The algorithm is up to 40% faster when compared to one of the fastest existing algorithms, viz., one-at-a-time step search algorithm...
With the explosion in the electronics market, PCB manufacturing has taken a very important place. The manufacturers use Gerber file as the only reference for PCB drawing since it gives the most accurate details of the solder pads to be etched on the PCB. Due to this feature of the Gerber file, we are using it in our proposal of PCB inspection mechanism. Gerber is a text file specifying the shape,...
Tampering images to create false ones using photo manipulation software is very easy. Tampering may be in the form of image splicing. Image Splicing involves the introduction of a selected region from one image into another with the aim to alter its content. Splicing may be in the form of blurred regions introduced via Gaussian blur. In this paper, a method based on inconsistencies in Gaussian blur...
Wireless Sensor Network (WSN) is the widely used network for the local environment monitoring ranges from health care heart pulses, pressure, sugar level monitoring to wildfire detection, military surveillance. In all these applications of WSN the major activity is the data collection and propagation which involve more energy than the sensing of the environmental factors. This paper is going to discuss,...
Wireless power charging powers the storage device without any cords which makes the device more compact, water proof, easy to use and provide even more comfort. The efficiency of power transfer depends on many factors, few of them are quality factor of the inductor coil, coupling coefficient, distance between receiver and transmitter coil, impact of core used for the coil. This paper discusses about...
This paper deals about the availability, visibility and Position accuracies of Indian Regional Navigation Satellites System (IRNSS). The position accuracies has been observed and plotted with respect to the standard time. The IRNSS — user receiver placed at school of engineering and technology, Bangalore. Indian space research organization has launched three Indian regional navigation satellites (IRNSS-1A,...
Normally images obtained from satellites are of low-contrast type which hides major information carried by the image. Hence, image restoration is necessary in the image processing domain to extract all the information present in the images. The low contrast satellite image restoration based on adaptive histogram equalization combined with Discrete Cosine Transform (DCT) and Discrete Wavelet Transform...
