Paper Title:

Experimental Analysis of Density of Sintered SiCp Reinforced AMMCS Using the Response Surface Method

Abstract:   The continuous development of technology in automotive manufacturing process demands new solutions which is  largely de-pendent on the development of lightweight, non-pollution for the environment materials of improved mechanical properties and also with a low cost production. According with these required characteristics of materials, the aims of this paper were to manufacturing Al-SiCp composites by powder metallurgy (P/M) processing route. Since density is a pre-dominant factor in the performance of powder metallurgy components, it has been primarily considered for the present investigation. An experimental investigation have been undertaken in order to understand the variation of density with respect to the variation of process parameters viz., variation of silicon carbide proportion, compacting pressure and sintering time. The relation among the various process parameters with density has been studied. A mathematical model has been developed using second order response surface model (RSM) with central composite design (CCD) considering the above mentioned process parameters. The mathematical model which developed in this investigation would help in predicting the variation in density with the change in the level of different parameters influencing the density variation. This mathematical model also can be useful for setting of optimum value of the parameters for achieving the target density.

Paper Title:

Reactor Physics and the Nuclear Fuel Cycle

Abstract:   Questions regarding the feasibility of fusion power are examined, taking into account fuel cycles and breeding reactions, energy balance and reactor conditions, approaches to fusion, magnetic confinement, magneto hydro dynamic instabilities, micro instabilities, and the main technological problems which have to be solved. Basic processes and balances in fusion reactors are considered along with some aspects of the neutronics in fusion reactors, the physics of neutral beam heating, plasma heating by relativistic electrons, radiofrequency heating of fusion plasmas, adiabatic compression and ignition of fusion reactors, dynamics and control of fusion reactors, and aspects of thermal efficiency and waste heat. Attention is also given to fission-fusion hybrid systems, inertial-confinement fusion systems, the radiological aspects of fusion reactors, design considerations of fusion reactors, and a comparative study of the approaches to fusion power. The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end, which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in the back end, which are necessary to safely manage, contain, and either reprocess or dispose of spent nuclear fuel. If spent fuel is not reprocessed, the fuel cycle is referred to as an open fuel cycle (or a once-through fuel cycle); if the spent fuel is reprocessed, it is referred to as a closed fuel cycle..

Thrust Bearing Governed Clinker Extraction System in Producer Gas Plant

Abstract:  In the process of Producer Gas Production; clinker/ash is formed as a waste material. This clinker is removed by equipment named as Ash Bowl which rotates on the “Guide Roller” by the application of hydraulic pressure. This process having many problems like formation of large size clinker which require excess hydraulic pressure, guide roller is unable to scatter the hydraulic pressure equally in all the direction on the ash bowl to crush the clinker, more hydraulic pressure is required for the movement of the ash bowl, more time is required to replace the guide roller for its maintenance. In order to eliminate above mention problems, guide roller has been replaced by the thrust bearing which improves productivity by reducing break down time, reducing total man power required & reducing maintenance cost.

In order to eliminate above mention problems, guide roller has been replaced by the thrust bearing which improves productivity by reducing break down time

Paper Title:

Optical and Magnetic Properties of Cu-Doped ZnO Nanoparticles

Abstract:   Effect of Cu2+ ions doping on the photoluminescence (PL) and magnetic behavior of ZnO based host material nanoparticles have been investigated. A simple chemical route has been employed for the synthesis of Cu2+ incorporated ZnO nanoparticles for the present study. The prepared synergetic nanoparticles were analyzed for structural confirmation under X-ray diffraction (XRD) and Raman spectroscopic investigations. XRD patterns of the prepared nanoparticles of different Cu2+ concentrations reveal some shifting in the peak positions compared to that of the pure ZnO, which is attributed to the structural deformation in the presence of Cu2+ ions. Furthermore, transmission electron microscopy (TEM) studies have been performed for studying their morphology. TEM studies clearly show the formation of spherical and quasi spherical shaped nanoparticles of ~ 50 nm diameters. It is revealed from PL studies that the band-edge/UV emission decreases, whereas, the visible emission is found to increase with increase of the doping concentration. The decrease in the band-edge emission can be attributed to the substitution of Zn2+ by Cu2+ ions in the ZnO lattice. Beside, these optical properties, magnetic properties of ZnO nanoparticles has also been found to be affected by Cu doping, investigated using vibrating sample magnetometer (VSM). It has been observed from VSM study that the ferromagnetic behaviour of ZnO nanoparticles is found to enhance with increase in doping concentration.

Towards OLAP - Based Data Mining Using Multidimensional Database and Fuzzy Decision Trees

Abstract:   In this paper, a new approach for data mining is described, coupling fuzzy multi-dimensional databases and fuzzy data mining systems, and achieving knowledge discovery from imperfect data. An architecture based on fuzzy multidimensional databases is given. It uses these kinds of data repositories to extract relevant knowledge from large data sets from the real world. According to several works that highlighted the great interest of the OLAP framework in the knowledge discovery process, this approach enhances the existing solutions. It provides a way to deal with data from the real world, and to apply flexible operations on data sets stored as multidimensional arrays, generating more understandable fuzzy rules. In recent works an extension of multidimensional database has been defined in order to handle imperfect information and flexible multidimensional queries.

An Improved Hindi Speech Emotion Recognition System

Abstract:   This paper presents the results of investigations in speech emotion recognition in Hindi, using only the first four formants and their bandwidths. This research work was done on female speech data base of nearly 1600 utterances    comprising   neutral, happiness, surprise, anger, sadness, fear and disgust as the elicited emotions. The best of the statistically preprocessed formant and bandwidth features were first identified by the KMeans, K nearest Neighbour and Naive Bayes classification of individual features. This was followed by artificial neural network classification based on the combination of   the best formants and bandwidths. The highest   overall emotion recognition accuracy obtained by the ANN method was 97.14%, based on the first four values of formants and bandwidths. A striking increase in the recognition accuracy was observed when the number of emotion classes was reduced from seven.

Paper Title:

A Study of Stiffness and Damping Characteristics of Conventional Fluid and Smart Fluid Applied to Squeeze Film Damper

Abstract:   Turbo machinery and other high speed engines play a vital role in industries worldwide. These high speed engines received considerable attention from the scientific and industrial community in order to extract better performance and higher reliability. Due to competitiveness and rapid technological advancement, the dynamic behavior of these machines is greatly dependent on the fluid film bearings. These fluid film bearings are used for its long life, low power consumption and versatile dynamic behavior. Despite of significant advancement in lubrication technology and advent of meticulous design procedures, bearings do fail in operation. Accordingly tribologists and practicing lubrication experts around the world are nowadays involved in design of general bearing system using entirely a design approach based on electrorheological fluids instead of conventional fluids to suit the requirement of high speed and heavy load operation. Smart fluid technology is an emerging field of research that leads to the introduction of Electro-rheological (ER) fluids.ER fluids are such smart materials whose rheological properties (viscosity, yield stress, shear modulus etc.) can be readily controlled upon external electric field which cannot be carried out in case of conventional fluids. This paper presents a comparative study of stiffness and damping characteristics of conventional fluids (damper oil) and electro rheological fluids (functional fluids) of external damper becomes a essential part of analysis. Calculations are carried out for different parameters like clearances, oil film thickness, fluid film width, different eccentric ratios etc. Thus the use of electro-rheological fluids introduces a new philosophy on the fact that the stiffness and damping can be changed by applying high electric field and thus minimizing the vibration of the structure during normal operation. This reduces the amplitude considerable and safe operation for high accuracy and efficiency.

Speaker Dependent Emotion Recognition from Speech

Abstract:   The speech signal is the fastest and the most natural method of communication between humans. Hence speech can use for fast and efficient way of interaction between human and machine. Speech is attractive and effective medium due to its several features expressing attitude and emotions through speech is possible. In human machine interaction automatic speech emotion recognition is so far challenging but important task which paid close attention in current research area. In this paper we have analysed emotion recognition performance on eight different speakers. IITKGP-SEHSC emotional speech database used for emotions recognition. The emotions used in this study are anger, fear, happy, neutral, sarcastic, and surprise. The classifications were carried out using Gaussian Mixture Model (GMM). Mel Frequency Cepstral Coefficients (MFCCs) features are used for identifying the emotions. It can be observed that, the percentage of accuracy is 75.00% for 32 centered GMM, 72.00% for 16 centered GMM and 66.67% for 8 centered GMM.

Paper Title:

A Novel Algorithm for Automatically Detecting Number of Clusters for Mining Communities in Heterogeneous Social Networks

Abstract:   Social media have attracted millions of user’s attention in recent years. In a distributed social network a community mining is one of the major research areas. Mining of network communities is a major problem now a day. This problem should be avoided. Several methods were proposed, but most of the methods of community mining consider the homogeneous network. But in distributed network there are multiple networks are interconnected with each other which are known as heterogeneous networks. Each network represents a specific kind of relationship. Same time each relationship plays an important place in a distinct situation. Mining of such an important community in a distributed environment is a difficult task. To overcome the above mentioned problem, this paper presents a novel Convergence aware Dirichlet Process Mixture Model (CADPM) for automatically mining the network communities in heterogeneous networks. The earlier Dirichlet Process (DP) mixture model is unsuitable in some situation. The number of clusters for community mining is unknown in prior. So the CADPM is proposed to handle the large number of data-cases.

Paper Title:

Secondary M6C Precipitation in Ni-20Cr-18W-1Mo Superalloy

Abstract:   The carbide precipitation behavior in Ni-20Cr-18W-1Mo superalloy solution treated at 1280 oC and then aged at 800 and 1000 oC has been investigated using SEM, EDS and TEM in the present work. Since the content of W and Mo is high enough (>6-8 wt.%) and the value of proportion (Cr at.% /(Cr+Mo+0.7W) at.% ) is 0.8206, satisfying the condition for the formation of secondary M6C, it is granular and W-rich M6C as secondary phase instead of lamellar and Cr-rich M23C6 that precipitates at grain boundaries when the aging temperature is not lower than 1000 oC. The precipitation of secondary M6C is suggested through a direct reaction between the metal elements and carbon atoms mechanism, in which the decomposition of primary M6C carbide provides the necessary elements. M is mainly W element with modest level of Ni, Cr and Mo. The result provides a foundation for improving the mechanical property of the alloy.

Static and Dynamic Analysis of Composite Laminated Plate

Abstract:   This work presents a static and dynamic analysis of Graphite /Epoxy composite plates. In the present work the behavior of laminated composite plates under transverse loading using an eight-node diso-parametric quadratic element based on First Order Shear Deformation Theory was studied, the element has six degrees of freedom at each node: translations in the nodal x, y, and z directions and rotations about the nodal x, y, and z axes . The static analysis includes the parametric studies on laminated plates to estimate the maximum deflection. The parametric study represented by variation in (aspect ratio, layer orientation, layer number, dimension of the plate and mesh size). The modeling of the plates was done by using ANSYS 12.0, and the results were compared with Finite Element Method code.The dynamic part of this study represented by evaluating the natural frequency of the plates. The boundary conditions considered in static and dynamic study, are simply supported and clamped boundary condition. In this study investigations were carried out on both square and rectangular composite laminated plates. The study start with isotropic plate of mild steel, and followed with orthotropic plate of Graphite/Epoxy composite .The results obtained from ANSYS program as well as Finite Element Method code, show a good agreement with the experimental results. The minimum deflection was found at an angle of 15 degree for clamped plate, and in case of simply supported plate the minimum deflection was found for angle 45 degree. It is also observed that the deflection for clamped boundary condition is less than in simply supported boundary condition for both isotropic and orthotropic plates. In isotropic plate the deflection in clamped plate is about 50% of simply supported. And for orthotropic plate the deflection for clamped is about (25 to 30)% of simply supported.

The Sound Channel Characteristics in the South Central Bay of Bengal

Abstract:   Environmental data collected along 92.5oE between 2.7oN and 12.77oN during late winter show a permanent sound velocity maximum around 75 m and an intermediate minimum between 1350 m and 1750 m. The axis of the deep sound channel is noticed around 1700 m. The shallower axial depth (~1350 m) between 7.5oN and 10.5oN coincides with the cyclonic eddy. Within the sonic layer (SLD), Eastern Dilute Water of Indo-Pacific origin and Bay of Bengal Watermass are present whereas its bottom coincides with the Arabian Sea Watermass. Sound speed gradient shows good relationship with temperature gradient (correlation coefficient of 0.87) than with salinity gradient. A critical frequency of 500 Hz is required for the signal to be transmitted through a channel of 50 m thickness and it increases to ~1 kHz for a layer of 20 m. Within SLD, salinity there is 1.54 m/s increase in sound per 1 psu increase in salinity. In the thermocline, the sound speed decreases by 1.95 m/s per degree drop in temperature, whereas at deeper depths pressure effect dominates (@ 1.4 m/s per 100 m depth).

Keywords: Bay of Bengal, Sonic Layer Depth, SOFAR Channel, Critical frequency, Watermass.

Design and Verification of High Speed Multiplier

Abstract:   Multiplier is one of the essential element for all digital systems such as digital signal processors, microprocessors etc. In this paper, a new high speed multiplier using booth recoding technique is presented. This algorithm can be implemented by using the radix-8 booth recoding process. The proposed multiplier reduces the partial product array by almost 3/4th the size of the bits. This reduction increases the speed of the multiplier. The proposed method can be extended to any higher radix encodings, as well as to any size square and rectangular multipliers. The proposed multiplier is compared with the standard multiplier and two’s complement multiplier using radix-4 MBE technique, demonstrated the good delay performance. These results show that the proposed multiplier is faster compared to other multipliers. The performance of the proposed multiplier is examined using verilog simulator in XILINX 12.4 version.

Design and Implementation of Zigbee Protocol in Wireless Sensor Networks

Abstract:   Recently, there has been a growing demand to incorporate multimedia content delivery over the Wireless Sensor Networks (WSNs). This feature could not only enhance several existing applications in the commercial, industrial, and medical domains, but could also spur an array of new applications. However, the efficient gathering of still images, audio, and video information in WSNs imposes stringent requirements on the throughput and energy consumption. Most wireless communication standards with high or moderate data throughputs do not focus primarily on energy efficiency. The IEEE 802.15.4 WPAN standard provides a widely accepted solution for low-cost and low-power wireless communication, with a potential to cater to many types of application scenarios. To design a wireless interactive data acquisition and control system is a challenging part of any measurement, automation and control system applications. Advancement in technology is very well reflected and supported by changes in measurement and control instrumentation. Data acquisition and control system based on AVR microcontroller (Atmega168) is presented. This makes use of the built in ADC of the microcontroller and thus the resolution is 10 bits i.e. one part in 1024. . The controlling program on an arduino read this input at pre-decided time intervals. The controlling program reads these values and process accordingly. Microcontroller programs are also developed and tested successfully.

Implementation of 2D Non-linear Morphological Image Processing on FPGA Based Architecture

Abstract:   Image processing requires high computational power and the ability to experiment with algorithms. Recently, reconfigurable hardware devices in the form of field programmable gate arrays (FPGAs) have been proposed as a way of obtaining high performance at an economical price. FPGA technology has become a viable target for the implementation of real time algorithms   suited to video    image processing applications. Morphing is a Technique used to transfer from one image to another. However, most morphological tools such MATLAB are not suited for strong real-time constraints. The unique architecture of the FPGA has allowed the technology to be used in many applications encompassing all aspects of video image processing. Among those algorithms, linear  filtering based  on  a  2D  convolution,  and non - linear   2D morphological  filters, represent a basic set of  image operations  for a number of  applications. This paper reports on the design and realization of an FPGA based image processing for implementation of morphological image filtering using a FPGA NexysII, Xilinx Spartan 3E, with educational purposes. The system is connected to a USB port of a personal computer, which in that way form a powerful and low-cost design. The FPGA technologies offer basic digital blocks with flexible interconnections to achieve high speed digital hardware realization.  The  FPGA consists  of  a system  of  logic blocks, such as  look  up  tables,  gates, or flip-flops  and some  amount of memory. The image will be transferred from   PC to FPGA board using UART serial communication/JTAG cable. After performing the required filtering/processing the result will be transferred back to computer. In PC both the results will be validated. A comparison between results obtained from MATLAB simulations and the described FPGA-based implementation is presented.

Comparison of Power Consumption in Array Multiplier with and without SVL Circuit

Abstract:   In this paper, we performed the comparative analysis of power consumption of array multiplier circuit implemented with two adder modules and Self Adjustable Voltage level circuit (SVL). The adder modules chosen were 10 transistor- Static Energy Recovery CMOS adder and 8 transistor CMOS (SERF) circuits. At first, the circuit was simulated with adder modules without applying the SVL circuit. And secondly, SVL circuit was incorporated in the adder modules for simulation.

A Survey on Broadcasting Protocols in VANETs

Abstract:   Vehicular Ad-Hoc Networks [VANET] is one of the fastest emerging technologies for research as there are many issues and challenges to be addressed by the researchers before the technology becomes commercialized. The challenges in VANET are, designing suitable routing protocols appropriate to the traffic model, providing security of the data and emergency messages, avoiding the collision of messages, avoiding flooding of messages, etc. The progress of research in the field of VANET promises to deliver a robust, safety, efficient and intelligent transportation in the future. This paper gives the review of various Rebroadcasting policies in VANETs. The reason for analyzing the broadcasting protocols is that, in most of the emergency situations, there is less time to make a handshake with other nodes in the networks, as the emergency message is to be delivered fast and efficient. Therefore broadcast based routing protocol plays a major role in almost all the safety applications. A detailed understanding of the existing protocol is needed before contributing new protocol for the upcoming research field.

Modelling and Flexibility Analysis of Hydro Cracker Unit

Abstract:   Hydro cracking is an extremely versatile catalytic process in which feed stock ranging from Naphtha to Vacuum Residue can be processed in presence of Hydrogen and catalyst to produce almost any desired products lighter than the feed. Primary function of Hydrocracker unit (HCU) is to maximize middle distillate production. First stage feed heater is a twin cell cabin heater with horizontal radiant tubes supported through 3 nos ladder type coil supports. Radiant Coil vibration was observed in tubes some remedial measures pertaining to mechanical aspects were studied and implemented. However, a need of comprehensive study to identify and minimize the coil vibration problem was felt to ensure reliable operation of the heater. In this work, Flexibility analysis of Heater Radiant Coil by modeling applied end conditions and various temperature cases was performed to verify the mechanical design and to understand the probable reasons of coil lifting. Fatigue analysis of the vibrating coil with maximum stress amplitude obtained by Flexibility analysis was performed. The maximum possible slug forces was calculated and dynamic analysis of reactor inlet piping along with heater coils was carried out to check whether slug, if any, has any impact. Maximum tube metal temperature for a definite span of operation was estimated. Purpose of this work is carried to identify the probable reasons of heater radiation tube lifting and vibration and to suggest remedial measures to continue safe operation of the heater. Heater tubes have a life of definite span which is directly related to the operating tube metal temperature. Due to furnace running on high tube metal temperature, rupture design study was also carried out for remaining life assessment of the tube. Based on the flexibility analysis of radiant tubes and maximum tube metal temperature calculation, heater operation could be sustained safely without unit interruption due to heater

The Effect of Clear Cutting on Runoff Height (Case Study: Noshahr, Iran)

Abstract:   Cut and exploitation methods used in forest trees affect hydrologic properties. In this study, clear cutting effects on runoff rate is performed in a 2100 m2  area and a similar plot is selected beside it as a control plot. Then the rate of runoff was measured during two consequent years within different temporal stages. Mann-Whitney tests were used for the comparison of two groups which was significant and non-significant in the first and second years, respectively. The results of correlation test also showed that the height of runoff in cut plot is higher than the control plot. In the second year, the rate of runoff in cut plot became closer to the rate in control plot because of herbal plants growth so the results were not significant while in the first year, the rate of runoff increased because of  plant cover remove.

A Novel Approach for Query Suggestions for Personalizing the Web

Abstract:   Web recommender systems predict the needs of web users and provide them with recommendations to personalize their pages. Such systems had been expected to have a bright future, especially in ecommerce and E-learning environments. However, although they have been intensively explored in the Web Mining and Machine learning fields, and there have been some commercialized systems, the quality of the recommendation and the user satisfaction of such systems are still not conclusive. In this paper we proposed a more robust approach that leverages search query logs for automatically identifying query groups for a number of different users and record the query logs and their respective sessions. The system uses query reformulation and click graphs which contain useful information on user behavior when searching online. Such information can be used effectively for the task of organizing user search histories into query groups. The proposed technique finds value in combining with keyword semantic similarity and filtering which applies knowledge gained from these query groups in various applications such as providing query suggestions for web personalization by favoring the ranking of search results.
