3 A Study on Mechanical Properties of Rubber Aggregate Concrete- A Review
Abdul Sayeed, Mohd Kashif Khan
Abstract - Concrete is the mixture of Cement, Sand and coarse Aggregate which is mostly used around the globe for the purpose of constructional activities. Rubber is also one of the most times taking decomposable products in this modern scenario. Rubber though is one of the most frequently used products but also causes adverse impact on the environment. For the purpose of reduction in the amount of waste generation in the form of the rubber products the most effective activity that can be implemented is the “reuse” of the waste Rubbers. In the researches conducted by the earlier researchers it is found that, when the concretes are rubberized the properties of the concretes such as Durability, Water Absorption Capacity, Damping Ratio, Flexural Strength and Crack Resistance enhanced. The properties which were reduced after adding the rubber along to the concrete are ductility and compressive strength.

Shashank Kaul, Hrittik Bhattacharjee, Barry C. K., Gaurav Verma, J. Gowthamy
Abstract - Technology is growing at an exponential rate. New platforms and frameworks are being developed to enhance the capabilities of what can be developed and how. Node.js is a platform that provides an event-driven and asynchronous I/O platform for development using JavaScript. Now, Express is a framework developed on the Node.js platform for building flexible web applications and is very rapidly growing in popularity amongst developers. However, for the cost of availability and performance we sacrifice confidentiality thus leaving applications vulnerable to many security threats. Threats such as Cross-site Scripting (XSS), Injection, DOS attacks and many more are now things that most people can learn on the internet, making systems that do not take precautions very vulnerable. We explore the possible ways someone with malicious intent can carry out attacks when running frameworks such as Express and implement methods to make Node.js web applications secure for production.

15 Enhancement of Performance of Axial Fans by Identifying and Resolving Stalling
Sivaperuman Kalairaj Manivannan, Jayashankar Dhileep Kumar
Abstract - Axial fans are used in almost all forms of built environment where life exists. The selection of axial fan is based on several factors such as pressure, airflow and efficiency. The environment of the location of the axial fans play a major role in the efficiency and the life period of the fan. Some the external factors such as increase in pressure and pollution cannot be eliminated in the environment which might lead to stalling condition. Although stalling condition cannot be eliminated in axial fans, it can be detected in early stages and external sources or change in designs could reduce the probability of fan getting induced to stall condition. This paper explains the method calculation the performance of the fan and analyzing its operating condition and solutions to overcome the stalling the fan might accidentally get into which reduces the efficiency or sometimes the fan itself.
16 Speaker Recognition System – A Review
Agrani Vishwakarma, Megha Soni
Abstract - Speech processing is emerged as one of the important application area of digital signal processing. Various fields for research in speech processing are speech recognition, speaker recognition, speech synthesis, speech coding etc. Speaker recognition has been an interesting research field for the last many decades, which still have a number of unsolved problems. The objective of automatic speaker recognition is to extract, characterize and recognize the information about speaker identity. A direct analysis and synthesizing the complex voice signal is due to too much information contained in the signal. Therefore the digital signal processes such as Feature Extraction and Feature Matching are introduced to represent the voice signal. Several methods such as Liner Predictive Coding (LPC), Hidden Markov Model (HMM), Artificial Neural Network (ANN) etc are evaluated with a view to identify a straight forward and effective method for speech signal. In this paper, the Mel Frequency Cepstrum Coefficient (MFCC) technique is been explained for designing a speaker recognition system.

M. Devika, M. Sundaraperumal, M. Malarvizhi, J. Chandramohan, M.Valan Rajkumar
Abstract - Multilevel inverters have become more attractive for researchers due to low total harmonic distortion in the output voltage and low electromagnetic interference. This paper proposes a novel single-stage quasi-cascaded H-bridge five-level boost inverter. The proposed five-level inverter has the advantages over the cascaded H-bridge quasi-Z-source inverter in cutting down passive components. Consequently, size, cost, and weight of the proposed inverter are reduced. Additionally, the proposed QCHB-FLBI can work in the shoot-though state. A capacitor with low voltage rating is added to the proposed topology to remove an offset voltage of the output AC voltage when the input voltages of two modules are unbalanced. A simple PID controller is used to control the capacitor voltage of each module. This paper presents sinusoidal pulse width modulation technique, circuit analysis, the operating principles, and simulation results of the proposed QCHB-FLBI. A prototype was constructed to validate the operating principle of the proposed inverter.

Rinki Yadav, Joginder Singh
Abstract - Workbench vice is commonly used apparatus in mechanical workshops. It has fixed and movable jaws with parallel alignment. In and out movement of the movable jaw is regulated using threaded screw and lever. A design process utilizes, prepares and processes a lot of data to envisage the appearance and expected behavior of the entity during operation. A 3D model design process not only saves time but also creates interactive designs for various applications. The design of bench vice plays a crucial role in several operations. In this paper, computer-aided design (CAD) software was used for modeling and simulation of the workbench vice. The model was made in the CAD package CATIA V5. CATIA is a very intuitive 3D CAD/CAM framework with the capacity to produce solid modeling. The bench vice model is represented by segments, which are connected by different types of joints. The model was made up of 3D solid segments with 6 (3 translation and 3 rotation) degrees of freedom. The profiles of different sections used for the model were solids and combinations of solids of different types such as a cylinder, cuboid, sphere, cylinder/cuboid prism etc. Geometric modeling and assembly of different sections of bench vice were performed in sketcher and part/assembly design tool. The kinematic analysis was conducted in DMU kinematics simulator.

D.Umakirthika, P.Pushparani, J.Chandramohan, M.Valan Rajkumar
Abstract - Recent development of the Internet of Things (IoT) and Smart Things provides an opportunity for the informationization for the automotive industry. This article describes Obstacle Detection and Alert System (ODAS) both incorporated as a single system for the obstacles such as speed breakers, barricades on the road using Internet of Things. Obstacle detection system uses in-built algorithm to detect an obstacle on the road using minimal vehicle parameters such as vehicle speed, steering angle. Obstacles locations thus marked by the detection system are stored locally and uploaded to cloud from time-to-time. Cloud server processes data from different vehicles and finalizes that there is a real obstacle at the particular location based on its own algorithm. Obstacles locations thus confirmed by the cloud server are downloaded to obstacle alert system from time-to-time, which alerts the driver about the obstacle on the road when the driver is nearing the location of the obstacle. This system also provides option to see obstacles location super-imposed on google maps so that user can plan his efficient route in advance. Existing systems only have road sign indications for obstacles such as speed breakers, barricades which the driver might not notice during driving, especially at night times. Existing google maps data do not have option to find road obstacles such as speed breakers, barricades information on it. The system aims to overcome these shortcomings by a dedicated system which provides audible and visual alert about road obstacles.

K. Satish Chandra, S. Swarna Latha
Abstract - The underutilization of radio spectrum is a major problem in the field of communication engineering. Since last decade, Cognitive Radio has been proved to be an efficient and reliable solution for the problem of spectrum underutilization. The limited availability of spectrum and power demands the optimal allocation of resources which is the most Challenging problem in the Cognitive Radio Network (CRN). Pure cognitive Radio Networks are unreliable in nature due to their opportunistic nature. So as a step towards the improvement of efficiency, reliability and performance of the network. Hybrid Cognitive Radio networks are proposed. These networks utilize the properties of both the licensed and cognitive RRs[3],[4]. they can be programmed and dynamically configured to use the best wireless channels available to avoid user interference and Congestion. This paper analyses the performance of Hybrid Cognitive Relay Network (HCRN) under Additive White Gaussian Noise (AWGN) and Rayleigh fading channels. The typical performance measures Such as Capacity, Energy Efficiency (EE) and spectral efficiency (SE) are formulated and numerical simulations are performed taking into Consideration different scenarios. The analysis and one of results will be helpful in determining the fundamental performance metric i.e. capacity for optimum usage of power and bandwidth.
