In the VLSI physical design, floorplanning is an essential design step, as it determines the size, shape, and locations of modules in a chip and as such it estimates the total chip area, the interconnects, and, delay. Computationally, VLSI floorplanning is an NP hard problem. So many researchers have suggested various heuristics and metaheuristic algorithms to solve the VLSI floorplan problem. The representation of floorplan is an important aspect of the floorplanning Stage. The floorplan representations have an important impact on the complexity and search space of the floorplan design. In this paper, we included studying and comparing PSO, SA and ACO as optimization algorithms for floorplanning and the representations involved in the VLSI floorplanning problem.

Voltage controlled oscillators (VCOs) are the most important basic building block of wired or wireless communication systems where these are mostly used as high frequency clock generating subsystems. The main objective of this paper is to design a high frequency VCO with a good phase noise performance and low power consumption. This paper presents an improved performance CMOS voltage controlled ring oscillator which is based on single ended differential pair configuration. The performance parameters of VCO like frequency, tuning range and power dissipation are also analyzed here. The proposed single ended ring VCO is implemented using 180 nm CMOS technology and 3.5 V power supply. It provides a wide tuning range from 5.2996 GHz to 6.567 GHz at 0.5 V to 2.5 V control voltage variation with 2.921 mW to 6.806 mW power consumption. The simulation results satisfies basic concept of VCO in which oscillation frequency linearly varies with supply voltage. The implemented design has high oscillation frequency, and also consumes less area as compared to existing current starved ring VCO.

Multi-focus image fusion is considered to be a vast research topic. Image fusion is the process in which source images are combined to get a single focused image. This focused image obtained contains relatively more information with all objects in focus and better description of scene. It is applied in various applications like medical imaging, remote sensing etc. Various multi-focus image fusion techniques are discussed in this paper, using focus measures such as energy of gradient of image, spatial frequency etc. The performance of these techniques depends on the methods used to determine the focused regions to get a fused image.

In grid connected photovoltaic (PV) systems transformerless inverters are widely used due to reduced size, weight and cost. However, common mode voltage reduction is one of the most key issues for transformerless PV inverters. In addition, several attractive single-phase transformerless inverter topologies have been reported to eliminate the common mode voltage based on converter topology and modulation strategy. Moreover, in literature three-phase topologies with reduced common mode voltage are not well investigated. In this paper, a novel three phase eight switch inverter (H8) and a corresponding modulation technique is proposed to reduce the common mode voltage. It is derived from the standard three-phase (H6) inverter but has different operating principles. Theoretical and performance analyses are carried out via MATLAB/Simulink to validate the effectiveness of the proposed H8 topology.

This paper presents the development of a numerical wave tank (NWT) using commercial Computational Fluid Dynamics (CFD) software, ANSYS Fluent 16.0. NWTs are widely used to analyse and optimise the performance of various wave energy converters, such as the Oscillating Water Column (OWC). A numerical modelling set-up is outlined which utilises Fluents Open Channel Wave Boundary Condition (OCWBC) along with a numerical beach scheme to dampen waves at the far field, ensuring no reflection back into the computational domain occurs. Linear waves are input into the NWT and free surface elevation and horizontal and vertical fluid velocities are compared to theory to quantify errors within the model. Variation in discretization error is observed with changing mesh density and a minimum criterion of 20 cells per wave height and 50 cells per wavelength is defined to ensure an acceptable level of model accuracy is achieved at a moderate computational expense. Further refinements show increased reduction in model error in both free surface elevation and velocity components beneath wave's peak, trough and inflection points, as expected. Further analysis focused on ensuring periodic independence was achieved and it was found that a minimum of six wave periods are required before fully developed waves propagate through the domain. The outlined numerical modelling method has quantified discretization error and outlined mesh requirements to reduce the overall error to acceptable levels for linear waves. Accurate free surface elevation and fluid velocity profiles will ensure that the NWT can now be used in future studies to analyse performance of wave energy converters and optimise device design.

During the last decade majority of research has been carried out in the area of sentiment Analysis of textual data available on the web. Sentiment Analysis has its challenges, and one of them is Sarcasm. Classification of sarcastic sentences is a difficult task due to representation variations in the textual form sentences. This can affect many Natural Language Processing based applications. Sarcasm is the kind of representation to convey the different sentiment than presented. In our study we have tried to identify different supervised classification techniques mainly used for sarcasm detection and their features. Also we have analyzed results of the classification techniques, on textual data available in various languages on review related sites, social media sites and micro-blogging sites. Furthermore, for each method studied, our paper presents the analysis of data set generation and feature selection process used thereof. We also carried out preliminary experiment to detect sarcastic sentences in “Hindi” language. We trained SVM classifier with 10X validation with simple Bag-Of-Words as features and TF-IDF as frequency measure of the feature. We found that this simple model based on “bag-of-words” feature accurately classified 50% of sarcastic sentences. Thus, primary experiment has revealed the fact that simple Bag-of-Words are not sufficient for sarcasm detection.

Ad Hoc network is a infrastructureless network which are mainly used for various types of wireless communication. This network is broadly categorized in to two types mobile ad hoc networks (MANET) vehicular ad hoc network (VANET) utilizes vehicles as mobile nodes in a MANET to constitute a mobile network. Many routing protocols for MANET have designed. The main protocols involved Ad-hoc On-demand Distance Vector (AODV), Destination-Sequenced Distance-Vector (DSDV) routing protocol and Link State Geographical Routing Protocol (LSGR). The performance of each protocol has been evaluated in terms of throughput, the normalized routing load, packet delivery ratio, delay etc. A network simulator-2.35 (NS-2) has been utilized for performance assessment of LSGR, AODV and DSDV. By considering the performance of each protocol it has been observed that LSGR protocol perform better than the DSDV and AODV protocol in ad hoc networks.

In Radar the good range resolution can be achieved by a short pulse. Short pulse systems are limited resolution because they are narrow band. Using pulse compression technique high range resolution can be achieved in radar system. The barker codes are known as bi-phase codes with minimum side lobes used in phase modulation in pulse compression technique. LFM and NLFM codes are used as frequency modulation. In this paper the wide band signals that is LFM and NLFM codes are modulates Barker codes to get good resolution while getting minimum side lobes and reduction in main lobe width. By introducing LFM in Barker codes grating lobes will be appeared in Autocorrelation function of LFM Barker sequence. To reduce the grating lobes and the main lobe width to get high delay and Doppler resolution, NLFM code is introduced in Barker codes and observed merit factor, side lobe levels, main lobe width and Doppler tolerance from Autocorrelation function as well as ambiguity function.
