An Internet of Things (IoT) are ‘things’ that com-municate in different networks. An IoT gateway which provides device connectivity and protocol translation is often expensive in case of small scale academic projects. In view of this, an Emulated IoT gateway is proposed that emulates the IoT gateway using a local computer in a cost effective way. The sensor data sent from sensor nodes connected in...
Resource provisioning refers to the selection, deployment and management of resources to ensure guaranteed performance for the applications. Efficient resource provisioning is a challenging problem since it is dynamic in nature and requires supporting applications with different performance requirements. In order to provide adequate resources for applications with different requirements that must...
This paper demonstrates the structure and the result characterization of a multi band microstrip patch antenna closely resembling Microsoft Calculator Accessory logo. This antenna is intended to be used for several applications. The substrate used is FR4 epoxy substrate with a relative permittivity of 4.4, dielectric loss tangent of 0.002 and a thickness of 1.6 mm. The design uses a probe feeding...
Big Data analytics has become important as many administrations, organizations, and companies both public and private have been collecting and analyzing huge amounts of domain-specific information, which can contain useful information about problems such as national intelligence, cyber security, fraud detection, marketing, and medical informatics. With more and more data being generated the ever dynamic...
Image segmentation is well known in partitioning a digital image into several segments. Recent days lower back pain in human being increases and so the lumber spine pathology detection becomes a predominant research area in Computer Aided Diagnosis (CAD) system. In the process of lumbar spine pathology detection, the segmentation of the Intervertebral Disc (IVD) is the major step as it identifies...
Business-to-Business (B2B) applications are developed predominantly based on service-oriented architectural style which is generally realized using a set of loosely coupled web services. These web services can be selected statically during design-time or dynamically during run-time. The functional and non-functional QoS requirements are typically captured in the Service Level Agreement (SLA) that...
Fingerprint is an important measure used to detect an unknown victim, suspect or witness. It has a major role in verifying records to explore links and matches between a suspect and a crime. Fingerprints are also used for security reasons, such as an entrance control at important buildings. But the quality of fingerprint images can easily get degraded by skin dryness, wet, wound and other types of...
This paper speaks about a novel method for detection and tracing of optic disc (OD) in retinal fundus images. Detection of diabetic retinopathy (DR), Glaucoma and Edema are the ones in which OD detection finds the meaning and need. The method proposed here introduces a unique concept of fractal analysis in its own way, exploiting the geometric structure of eye called Pixel Based Multi Fractal Analysis...

An intelligent receiver based on Radial Basis Function (RBF) neural network for MIMO system is developed. Due to its fast maximum-likelihood(ML) decoding, STBC is commonly used in MIMO system. However, most of the existing STBC methods rely on the availability of accurate channel state information (CSI) at the receiver. Furthermore, the complexity of the ML algorithm grows exponentially with the number...
Many multiplayer card games have interesting structures that can be exploited while designing a computer application to simulate these games. Critical features that most games have are that they are turn based and have common data types like Cards and Decks. This paper aims to demonstrate certain design patterns for implementing multiplayer card games that are capable of scaling well and are easily...
Spectrally efficient orthogonal frequency division multiplexing (OFDM) offers an ideal solution to inter symbol interference (ISI), by maintaining the orthogonality among subcarriers. For a multi carrier (MC) communication system, the wireless channel impulse response (CIR) varies rapidly under severe channel fading conditions. Fixed step size (FSS) adaptive filtering (AF) provides a way out for channel...
Plants make the world, a greener and a better place to live in. Although all plants need water to survive, giving them too much or too little can cause them to die. Thus, we need to implement an automatic plant watering system that ensures that the plants are watered at regular intervals, with appropriate amount, whenever they are in need. This paper describes the object oriented design of an IoT...

Face recognition is widely used in computer vision and in many other biometric applications where security is a major concern. The most common problem in recognizing a face arises due to pose variations, different illumination conditions and so on. The main focus of this paper is to recognize whether a given face input corresponds to a registered person in the database. Face recognition is done using...
This research concept deals with Parallelizes PSO-SA model which combines the particle swarm optimization (PSO) and Simulated Annealing (SA). Parallel PSO-SA operates by parallelizing the operation of each of the particles and Multistart PSO runs parallel several normal versions of PSO embedded with Simulated Annealing in parallel. The experimental results were conducted on benchmark data sets and...
Living in an information age the whole earth is a small globe in our hands with the advancements of computers, smartphones etc. The usage of computers in our day-to-day activities has increased enormously leading to both positive and negative effects in our lives. The negative effects are related to health problems such as Computer Vision Syndrome (CVS) etc. Prolonged use of computers would lead to...
This paper, a novel design of Microstrip antenna with multi band of operation has been presented for wireless communications. This antenna is very distinctive in shape and has been fed through 50Ω coaxial feed line. The Beauty of the antenna lies in four band, S11≤ (−10) dB for 2.06 GHz, 10.92 GHz, 16.30 GHz and 24.24 GHz with a simulated gain of 6.2572 dB, 5.2190 dB, 6.9254 dB, 5.1175 dB and 6.3533...
