CIPHER BASED ACKNOWLEDGEMENT SCHEME FOR MANET by Neha 

Abstract
MANET is a collection of independent networks. In mobile ad-hoc network, mobile devices are connected through various wireless links. The MANET works on a constrained bandwidth. The network topologies are rapidly changing and may vary from time to time. Each and every device must act as a router and route their packet for transferring any information among each other. Due to its topology, resource constraints, no centralized infrastructure and less security, it is endangered to different attacks and black hole attack is one of them. In this attack, the malicious node claim itself as having the smallest path to the destination and falsely replies to the route requests, and drops all receiving packets. In the past various models and approaches, had been proposed for performance enhancement and detection of malicious nodes in MANET. Various modifications has been done to routing protocols and best path selection, IDS based system has been developed but all of above modification does not provide better data wholeness. To overcome this problem in MANET, in the proposed work malicious node detection and encryption based approach has been used. In the proposed work, AES based encryption approach has been used with AODV routing protocol so that data integrity and confidentiality can be achieved. In this process data messages has been first converted to hexadecimal and then round sub keys were used. After this process shifting of rows and mixing of column has been done so that data can be encrypted and convert to cipher text. Cipher data can be decrypted using on key at decryption process that is reverse of encryption strategy using AES. In the proposed work reverse tracking mechanism has been used for detection of attacker nodes, that degrades performance of the network. In the process of reverse tracking mechanism all the nodes that are one hop neighbor from the source node has been identified by transmitting a message and the reply message has been verified if any message is received from other than single hop communication node then the detection mechanism becomes active for detection of black hole and grey hole attack over the network. Mobility speed is the major concern in MANET that affect the performance of the network. High mobility degrades performance of the network due to lack of route establishment. In the simulation various performance evaluation parameters have been analyzed, which were used for validation of proposed work. These parameters (packet delivery ratio, end to end delay, throughput and network overhead) have been evaluated with respect to time as well as mobility. On the basis of obtained results, it was concluded that proposed approach provide better performance than EAACK approach.

COMPUTER VISION BASED VEGETABLE GRADING AND SORTING SYSTEM by Sukhpreet Kaur 

Abstract
Since ages, agricultural sector plays an important role in the economic development of a country. In recent years, industries have started using automated systems instead of manual techniques for quality evaluation. In agriculture field grading is very necessary to increase the productivity of the vegetable products. Everyday huge amount of vegetables are exported to other places and earn a good profit. So quality evaluation is important in terms of improving the quality of vegetables and gaining profit. Traditionally, the vegetable grading and classification was done through manual procedures which were error prone and costly. Computer vision based systems provides us accurate and reliable results that are not possible human graders/experts. This research work presents a vegetable grading and sorting system based on computer vision and image processing. For this research work, a tomato has been used as a sample vegetable. A total of fifty three images were acquired using own camera setup. Afterwards, segmentation using Otsu’s method was performed so as to separate the vegetable from the background. The segmented images, thus obtained, were used to extract color and shape features. There after grading and sorting was performed using back propagation neural network. Twenty eight images were used for training the network and twenty five images for testing purposes. The proposed system has shown 92% accuracy rate. Also the system was compared with existing tomato maturity based grading system. The present system outperformed the existing system and is proposed for industry use.

SOIL STABILIZATION USING RICE HUSK ASH AND POLYPROPYLENE AS WASTE MATERIAL by Vinod Kumar Mishra 

Abstract
Soil is very significant in civil engineering construction. Soil having poor engineering properties may create many problems. For construction of civil engineering structure the soil should have good engineering characteristics for its adequate strength. To make the soil suitable for the desired level of construction, it is necessary to augment the engineering characteristics of soil. There are various methods of improving the engineering properties of soil. The soil stabilization technique is one of the most effective tools used now days for enhancing the engineering properties of soil. But the soil stabilization is becoming costly day by day due to the rise in cost of stabilizing agent like cement, lime etc.On the other hand large quantity of waste material produced from the different industries like fly-ash, rice husk ash, plastic waste, paper mill slag etc. create negative impact on the environment causing environmental pollution and hence safe disposal of these waste material is required .Utilized these waste material as stabilizing agent for improving engineering properties of poor soil is best solution and also using these waste material as a stabilizing agent not only solve the dumping issue but as well as minimize the expenditure of stabilization. In this research work, an extensive laboratory work have been done to explore the use of local available RHA as agricultural waste and waste fibres of the polypropylene for the improvement of the various properties of the Clayey (CI) type of soil obtained from proposed site of D.A.V. public school (junior wing) behind cloth market Ambala City, Haryana (India).In present research work to explore the effect of waste fiber of polypropylene in different length and percentage as reinforcement mixed with optimum amount of RHA stabilized soil. The effect on engineering characteristics of clayey soil such as Maximum Dry Density, Optimum Moisture Content, Direct Shear Stress, Unconfined Compressive strength was investigated. The investigation results show that with the addition of rice husk ash and fibre contents the Maximum Dry Density decreases and the optimum water content increases, the most appropriate percentage of RHA is found to be 9%, the Shear parameter i.e. Cohesion (c) of the 9% RHA stabilized soil reinforced with waste fibres of polypropylene with 20 mm length and 0.30% weight of polypropylene by weight of dry soil sample, is found to be increased by 28.05% and angle of Shearing Resistance (Φ) found to be increased by 64.24% and the Unconfined Compressive Strength of the 9% RHA stabilized reinforced soil found to be increased by 59.34% with 20mm length and 0.30% by weight of dry soil sample. The optimum percentage of clayey soil: Rice Husk Ash: Polypropylene for improvement of clayey soil found to be 90.7: 9: .3 of 20mm length

A STUDY TO INVESTIGATE VIBRATION EXPOSURE AMONG ON ROAD TRACTOR VEHICLE DRIVERS by Chander Prakash 

Abstract
For being an agricultural country, over 60 percent of India’s land area is arable, contributes to 16 percent of GDP and employment of 65 percent of total workforce. All such contributions couldn’t be possible without modernization of agriculture by means of mechanized machinery such as tractors. On the contrary, tractors have been found to be a major source of occupational whole body vibration which may affect human ride comfort. So, present study has been undertaken to investigate occupational whole body vibration exposures among tractor drivers while performing on-road as well as in-field harrowing operation. Ten (10) male drivers having mean age 25.10±3.78 years, body mass 75.3±8.54 Kg, stature 1.548±0.01 meter and body mass index 31.43±3.48 Kg/m2 were considered for conducting experimental runs. A total of three hundred sixty (360) experiments were conducted. It has been found that majority of vibration exposure levels in vertical axis were found to be exceeding exposure action value (EAV) as recommended by ISO 2631-1 1997 under on-road operations at 1500 as well as 2000 RPM levels. However, such exposure levels were observed to be exceeding EAV level in x, y and z axes under harrowing operation at 1500 RPM. Moreover, exposure values found above than exposure limit value (ELV) at 2000 RPM. Consequently, postural variation also showed varying vibration responses among all the selected subjects under different experimental conditions. The daily exposure A(8) and daily dose (VDVexp) value were also exceeding ISO exposure limits which may lead to severe health disorders if exposed to such vibrations for long term. Although, 1/3 octave analysis depicted a dominant frequency range of 3.15-4 Hz among all the subjects under entire on-road experimentation. While, frequency about 10 Hz found to be dominant under harrowing operation at both 1500 and 2000 RPM levels. Hence, it has been concluded that tractors needed more
designing efforts in order to damp vibration levels. In addition to it, suitable working time might be planned for operating tractor for various applications accordingly so vibration levels remains up to ISO exposure limits.

DESIGN AND OPTIMIZATION OF 14nm 7-FIN SOI FINFET  by Gurleen Kaur

Abstract
Scaling of standard CMOS is becoming difficult due to rising subthreshold leakage and gate leakage.
FinFETs i.e. Multi-gate FETs have come out as the most assuring contenders to extend the scaling of
CMOS insub-25nm region this is because of more electrostatic control due to use of multiple gatesover the channel which lowers the coupling between drain and source in the subthreshold regime. Both bulk and SOI FinFETs are capable of attaining similar performance. Bulk FinFETs need more convoluted doping implementation. Variability control is complex in bulk FinFETs. Dielectric isolation in SOI FinFETs results in reduced leakage current and parasitic capacitances. Sharper subthreshold slope, lower mobility degradation and smaller body effect can be achieved with SOI MOSFETs when operated in full depletion mode. Driving capability for small voltage designs can be increased by use of SOI FinFETs. This results in diminished threshold voltage roll off, reliable narrow junctions, absolute removal of latch up problems. In this thesis work, 14nm 7-fin SOI FinFET is designed and analysed using Visual TCAD. And it’s V-I characteristics are obtained and also Ion , Ioff , Ion /Ioff ratio, SS and Vth is calculated from that. And Ion /Ioff ratio is optimized w.r.t. Temperature and Oxide thickness variation using PSO.

PERFORMING ANALYTICS ON HEALTHCARE DATA USING HADOOP HIVE by Upasna Sharma 

Abstract
Big Data analysis poses huge challenges for organizations to extract meaningful information considering huge variety and volume of data made openly available related to finance, business, healthcare, etc. Not only the people but even machines are generating data too e.g. satellites, washing machines, wearable gadgets, buildings equipped with recorders, smoke detectors and cameras, wind turbines, and what not. Sensors are installed on so many devices which contribute to Big Data generation to a large extent. Now the problem is that there is already gigantic amount of data, but the main area of concern is how to analyse the data to draw new inferences from it and gain some knowledge. The main aim of the proposed work is to analyse large data sets effectively and compare the performance of Hive over Map-Reduce, Impala and Hive over Spark based on data load time and average query time. Also, query optimization has been done using compression algorithms like ORC and PARQUET. ORC is the latest compression algorithm in the domain of Hadoop. Impala is better than other platforms in terms of query execution on a simple text file as it provides the least query execution latency. Hive over Spark is a great platform to store and analyse large data sets by combining the techniques of partitioning and compression. There is approximately 50% improvement in query execution time of Hive MR by using compression format ORC and Parquet. Impala does not work on ORC format. So, it is used only on PARQUET format and shows 60-70% improvement in query execution performance.

ANALYSIS OF SHEAR WALL WITH DIFFERENT CONFIGURATION IN MULTISTOREY BUILDING by Manvinder Kingra 

Abstract
Shear wall is a structural system composed of braced panels (also known as shear panels) to counter the effects of lateral load acting on a structure. Wind and seismic loads are the most common loads that shear walls are designed to carry. Shear walls resist in-plane loads that are applied along its height. A diaphragm, collector, or drag member generally transfers the applied load to the wall. They are built in wood, concrete, and CMU (masonry). Shear walls must provide the necessary lateral strength to resist horizontal earthquake forces. The present thesis is made in the interest of studying and analysis of various research works involved in enhancement of shear walls and their behavior towards lateral loads. As shear walls resists major portions of lateral loads in the lower portion of the buildings and the frame supports the lateral loads in the upper portions of building, which is suited for soft storey high-rise building, as in India base floors used for parking and garages or officers and upper floors are used for residential purposes. Shear wall is designed in a high-rise building and in earthquakes prone areas. In this research, the shear wall is analyzed by using SAP 2000 software. The main function of shear wall is to resist lateral force acting on the structure by acting like a deep beam. Normally they are located inside building and mostly walls that support lift is reinforced to act as shear walls. Linear and Nonlinear Analysis is done which includes various load combination based on the Indian Code provisions i.e. IS standard (IS 875 (PART I & PART II) – 1987) and Seismic load as per as IS standard IS 1893 PART I – 2007 and IS 456- 2000. This report includes various chapter in which applied to putting together of G+10 floor situated in ZONE IV in Ludhiana. Shear force, bending moment and floor drift be computed and location of shear wall with heights and types would be found. For this study, 11-storey building with a 3.2 -meters height for each storey, regular in the plan is modeled. These buildings are designed in keeping with the Indian Code. The buildings are assumed to be fixed at the base. The sections of structural elements are rectangular. Storey heights of buildings are assumed constant including the ground storey. Five different models are studied with different positioning of the shear wall in the building. Models are studied in zone IV comparing lateral displacement for all models.

NOVEL APPROACH FOR DRUG DISCOVERY USING NEURAL NETWORK BACK PROPAGATION ALGORITHM by Neha Tandon 

Abstract
A complex structure that focuses on the analysis of variety of levels in regular manner is known as the ontology process. It is different from the methods that evaluate the ontology in a direct manner. When there is a need to transcendently automate the evaluation and not totally leaving the work on clients is the main focus here. There has been an involvement in the programmed learning methods for constructing the ontology which is completely a level-based method. There are different strategies included for various levels. There are all these levels that are defined at various levels. The hominidae species is represented as base class in the ontology method. Here the class, object properties as well as data properties are present. There are three classes further present which are gene, Go_id and the gene functionality. For the purpose of mapping the two base classes, the object properties are utilized. Basically it involves the five different properties that are belongs_to, has_go, has_gene, has_evidence, and has_functionality. In this work, technique is been proposed which is based on the neural networks which will mark the area for which the drug need to be discovered. The proposed technique is implemented in MATLAB and it is been analyzed that accuracy is increased and execution time is reduced.

 SMOOTHENING OF CONCATENATIVE GENERATED SPEECH by Sarpreet Kaur Gill 

Abstract
Speech Synthesis is the procedure of changing texture to speech signal. Basically, it is an artificial production of human speech. There are mainly three methods used to build Text To Speech (TTS) systems, namely, Articulatory, Formant and Concatenate synthesis. One of the main problems is the occurrence of various discontinuities among two concatenative samples. When the connection between various speech samples is well audible, it deals with the gapping scenario. The speech which is synthesized can work very genuine if the discontinuities at the points of the concatenation are noiseless. But the problem arises when these concatenations of the joins are clearly audible, their presence can create problems to the auditor and it deals with the reduction of the overall quality measure for the synthesis of speech samples. Databases containing longer discourse units and the assortment of yield is restricted there will be lesser connection focuses. In frameworks where discourse is made by consolidating substantial number of littler discourse units, there is an expansion in the quantity of joins and subsequently discontinuities. So our proposed system deals with the hybrid filtration with hidden markov model for the speech synthesis. The filtration process deals with the beam forming approach which will filter out the high frequency components and will eliminate it from the signal. Then HMM will train the system and as a result of which we will get the transition and estimation probabilities. The evaluation of the output speech signal is done on the basis of two parameters Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR). For smoothen signal the value of Mean Square Error should be low and the value of Peak Signal to Noise Ratio should be high.

Biogas production from food waste and effect of its slurry on Plant growth by Somil Thakur 

Abstract
Increasing population has increased the amount of waste generation leading to a new crisis in the form of solid waste management. Scientists around the world are focusing on the alternatives to utilize this solid waste in an energy efficient way. This solid waste includes both biodegradable and non-biodegradable materials. Kitchen waste forms a major portion of this biodegradable waste. The presented study is based on utilization of this abundant biodegradable waste for producing biogas which is the best source of renewable energy. Biogas production is an age old concept to produce energy using mainly cattle dung. However, the slurry produced from such plants has always been an issue to discuss. This study provides a solution to this problem by utilization of slurry as compost. The total biogas production was 4290ml, 4450ml, 6430ml, 12210ml, 11175ml in Digester number A, B, C, D, E respectively after 33 days of study. Also best growth of ladyfinger plant was observed by slurry of digester number E. This is a novel work focused on food waste as well as slurry management through biogas production. Different process parameters were analyzed during the process of biogas generation i.e. Total Solids, Suspended Solids, pH and Volatile Fatty Acids etc. This process technology can be further used to set-up small scale biogas plants in households for proper use of gas generation by food waste under natural environmental conditions and efficient usage of slurry
produced.

Stabilization of Sewage Sludge by Vermi Composting by Sonakshi Gurung 

Abstract
Toxic concentrations of heavy metals have been reported to be present in STPs as many industries dispose their waste directly in domestic sewers without prior treatment and thus they are carried to the sludge generated during the treatment processes. This sludge is directly fed to fields without any proper analysis or treatment which ultimately enters the food chain. This problem can be handled by biodegradation methods to lessen its threat to the environment. This study used one such technique of vermi composting for stabilizing the toxic sludge. Aerobic sewage sludge was assembled from the SBR unit of sewage treatment plant situated at Bhattian, Ludhiana. The work aimed at reducing the heavy metal content (Cr, Cd, Ni and Pb) from aerobic sewage sludge by the vermicomposting method using earthworm Eisenia foetida with the different activators (Cow Dung, Poultry Manure and Horse Dung) at 50:50 proportion by mass for 105-day period. Vermi-beds of size 3´×3´×0.5´ were set up and the raw material was inserted in the said proportions. The lab and field analysis were performed on regular intervals. The parameters considered for the study were pH, moisture content, total carbon, total nitrogen, C/N ratio, total potassium, total phosphorus and the heavy metals (Cr, Ni, Cd and Pb). The results showed that both cow dung and poultry manure are commensurable for causing the decomposition of the sewage sludge and were better than horse dung. And for stabilizing the heavy metals, cow dung acted as the best activator. The lab analysis depicted high values of chromium which made it the main toxic element that needed removal. The study further showed that there are high heavy metal contents in the activator themselves which contribute to the high values in the pit material at the initial stages but still considering their stabilization effect they are added. the sewage sludge waste but in case of heavy metals, cow dung acts as the best stabilization material.
