We live in the age of After Google (AG), where information is just one click away and talking just one touch away. The near future of the AG age is the Internet of Things (IoT), where physical things connected over a network will take part in Internet activities to exchange information about themselves and their surroundings. In other words, the IoT is nothing but a computing concept in which everyday objects with embedded hardware/devices are connected to a network or are simply online. © 2012 IEEE.

In this paper, a new scheme is proposed in Orthogonal Frequency-Division Multiplexing (OFDM) systems to reduce Peak-to-Average-Ratio (PAPR) without any influence on Bit-Error-Rate (BER). The high PAPR will leads to the non-linearity section in High Power Amplifier (HPA), which will degrade the performance and brings Inter Symbol Interference (ISI) in OFDM systems. In this paper, the high order prediction filter is implemented for reducing PAPR level in OFDM based system and comparing the results of Weighted OFDM scheme, predicted scheme and with conventional OFDM system. © 2017 IEEE.

Cuckoo optimization Algorithm (COA) is employed for the optimization of linear and non uniform circular antenna arrays. COA is a novel nature inspired computing algorithm which is motivated by the life of Cuckoo. Like other nature-inspired algorithms, COA is also a population-based method and uses a population of solutions to proceed to the global solution. The method of COA is used to determine a set of parameters of antenna elements that provide the required radiation pattern. The effectiveness of COA for the design of antenna arrays is shown by means of numerical results. Comparison of results of COA is made with that obtained using other popular methods. The results reveal the superior performance of COA as compared to other techniques both for design of linear and circular antenna arrays.

Integration of DWDM in Optical wireless communication has undoubtedly revolutionized the satellite communication systems for use in the coming future. Thus OWC systems have become popular due to their outstanding performance uniqueness. This paper looks into the performance of Inter Satellite Optical Wireless Communication system link using DWDM multiplexing technique for long distance transmission. The Inter satellite link has been modeled at a data rate of 10 Gbps for communication range of 5000 kilometers. Furthermore, it demonstrates a comparative analysis of RZ (Return to zero) and NRZ (Non-return to zero) modulation formats by varying the levels of input power.

Regression testing is a kind of software testing that seeks to find out new software errors, or regressions, in existing functional and non-functional areas of a system after modifications such as enhancements, patches or pattern-changes, have been build to them. Automation tools are required for regression testing. Regression testing is to verify whether a modification in one division of the software affects other division of the software. This testing is done to build that new code modifications should not effects on the existing performance of the software. It ensures that existing code still works with new code modifications are done. Regression testing is to ensure that modification made to system, such as adding new functions or changing existing functions, have not unfavorably affected functions of the software that should not modify. In this paper, enhanced in genetic algorithm has been proposed which increases the efficiency of test prioritization and increase reliability of the software. © Research India Publications.

Text retrieval is a popular technique applied for software engineering tasks. These are at least 20 tasks including reuse, code retrieval, reverse engineering, bug tracking etc. In software engineering, component based software development or component based software engineering is a more effective and reuse based approach. This approach has attained importance from researcher point of view as well as company prospective. Retrieving component from repository is a challenging task. This paper look into how k mean work on set of requirements documents and test cases by clustering documents with similar properties into single course and those with unlike properties into another course and to resolve static clustering in case of k mean by proposing the approach for dynamic requirement clustering with usable test cases. © Research India Publications.

The consumption of various forms of plastics is a challenging environment protection issue. All forms of consumed plastic become waste and require large areas of land for storage because several tons of waste plastics cannot be fully recycled at once. The low biodegradability of plastic and the presence in large quantities of waste plastic negatively impact the environment. Previously, various studies were performed to identify safe and environmentally friendly methods for disposing of plastics. Recently, various forms of plastics have been incorporated in concrete to prevent the direct contact of plastics with the environment because concrete has a longer service life. However, this method is not a dominant method for disposing of waste plastic. This paper presents an overview of some published research regarding the use of waste plastic in concrete. The effects of waste plastic addition on the fresh, mechanical and thermal properties of concrete are also presented in this paper. © 2015 Elsevier Ltd.

Free Space Optics (FSO) link offers gigabit per second data rates with less system complexity. However, the availability of link under various atmospheric conditions is a major concern. As these links are highly weather dependent, thus increase in signal attenuation under these conditions reduces the link efficiency. This paper evaluates the effects of bad weather conditions on FSO link having range 500 meters up to attenuation of 70 dB/km. The suitability of three optical transmission windows that are 850 nm, 1310 nm and 1550 nm, with the FSO link is analysed and compared in this work. Simulation parameters such as Quality factor, minimum BER and Eye diagram are taken into consideration. The results of analyzer for various transmission windows are compared to find out the most suitable wavelength of transmitter under adverse weather conditions for reliable communication. © 2016 The Authors.

We study the initialization effects via nuclear charge radii on fragmentation for the whole mass range of periodic table by taking isospin asymmetric nuclear reactions using Isospin dependent Quantum Molecular Dynamics (IQMD) model. Calculations are performed for three different isospin dependent nuclear charge radii parameterizations as well as for liquid drop model (LDM) radius. Our study reveals that there is a significant role of nuclear charge radii on fragmentation in heavy ion collisions at intermediate energies. The influence on fragmentation due to initialization via nuclear charge radii is more for heavier colliding nuclei compared to lighter colliding nuclei and this influence further reduces with increase in incident energy for lighter colliding nuclei and remains nearly constant for heavier colliding nuclei. Moreover, isospin dependent radius is more suitable to reproduce experimental findings of INDRA Collaboration. © 2014 Elsevier B.V.
