Distributed Denial of Service Attack Detection Techniques
-Aman Sachdeva ; Mr. Binayak Parashar
Internet usage is increasing day by day as well as the attacks on the sites. Distributed denial of service (DDoS) is one of the such type of attacks. DDoS disable the server by flooding invalid requests with invalid or spoofed addresses, due to this the server’s buffer gets overloaded and bandwidth of server get exhausted and server stop its services. left undetected, can be very dangerous to the entire network. If organizations can detect these types of attack in advance then organizations will be saved from loss of these attacks, there are many preventions techniques which can detect these types of attack but while choosing one of these technique questions arise which technique should be used? Which is the best? IP Traceback technique is a DDoS detection technique, which is used to trace the path of an IP packet to its origin so one can find out the true identity of the attacker and can detect the path characteristics. Different types of IP Traceback Techniques are available. In this paper we represent comparative study of different IP Traceback techniques basis on different parameters so anyone can take idea according to his requirements which technique is best.

A Review on Seismic Analysis of Multi-Story Building with Underneath Satellite Bus Stop Having Service Soft Story and Moment Transfer Beams
-Bharath Kumar ; Bharath Kumar; Prof. Vishwanath B Patil
Generally RC framed high rise structures are designed without regards to structural action of masonry infill walls present. Masonry infill walls are widely used as partitions. They are considered as non- structural elements. RC frame building with open first storey is known as soft storey, a similar soft storey effect can also appear, at intermediate storey level if a storey used as a service storey. The soft storey located in the lower part of the high rise building especially the first storey is very undesirable as it attracts severely large seismic forces. In satellite bus stops the ground soft story is of double height than the normal buildings and has sufficiently larger spans for movement of buses, so the effect will be more. At the same time, the soft storey located in the upper part of the high rise building does not significantly affect the performance compared to the performance of the fully infill frame. Read More...

Reduction of Fatigue of Employees by Application of Ergonomic Principles
-Dr. S. Bharath ; Dr. G. S.Prakash; Mr. Rohan Shetty; Mr. Prajwal R Gowda
The study was carried out at the Injector Manufacturing unit of an MNC company located at Bengaluru, India. The logistics unloading section was considered for this study in order to reduce stress and fatigue caused to the operator(s) due to load handling of components. The operator/driver had to drive the truck to the unloading bay and unload the materials on to a pallet from where he would have to place it in an intermediate location after the quantity check. All of these activities are to be completed within a specified time interval and is usually carried out by a single operator. The load handled by the operator is a cumulative factor of the weight of the crates, operating scenarios, lifting height and grip distance. The cumulative load handled by the operator was observed to be almost 3 times the allowed specifications. The data collected was analyzed in terms of lifting index for the particular activity and for the whole task. Based on the lifting index obtained and analysis of the input parameters, a standard work style is determined and 3 common proposals were made as to reduce the stress caused to the operator in the long run.

-Mr. Madhav Jagannath Salunkhe ; Prof. K. Sujatha
A common technique that is also widely used in communication systems is the Adaptive Modulation (AM). In this technique the most appropriate type of modulation is selected in addition to size of the constellation depending on the Signal to Noise Ratio (SNR) measured at the receiver side. AM technique is employed within the systems of cooperative diversity in order to obtain throughput enhancement from SNR gain. The diversity is also considered another common technique that is employed in mitigating the fading effect. Time diversity methods are not able to be employed for channels of frequency non-selective and slow fading types. The AM and cooperative diversity techniques, which are considered two common and deployed algorithms in improving the wireless communication performance.

A Review on Effect of Nano-particle on Wear Characteristics of Journal Bearing
-Sumeet A. Datar ; Prof. P. R. Sonawane
Friction and wear are the most important parameter to decide the performance of any bearing. The occurrence of the faults associated with Journal bearing is one of the most common cause of forced outages in rotating systems. During working bearing subjected to a progressive wear process, which can be accentuated in starts and stops or during the passage through the critical speed of journal. Therefore, investigation of friction and wear behavior of materials is important because of the adverse effect observed in performance and life of machinery components. After the test on wear machine, we found that additives can reduce wear by keeping the less co-efficient of friction, which helps to minimize the power loss due to friction. Nano-fluids are efficiently used to improve the tribological properties of bearing lubrication. Read More...

-Krishnananda Basumatary ; Dr. Amita Soni
Signal fading is one of the major concerns in wireless communication. Many different ways had been opted till now to mitigate signal fading. There is still a lot of research left to be done on signal fading. Diversity is one of the many techniques that can be used to mitigate fading. It is a burning topic nowadays. Space diversity is one of them. Based on this space diversity, many types of relay network systems, MIMO systems etc. have been developed. In these mentioned systems, the data signal is conveyed to the receiver over multiple independently fading signal paths. and then, combining these signals at the receiver appropriately, helps in removing noise. In this paper, cooperative wireless system based on decode and forward(DAF) one-way relay technique and adaptive modulation(AM) has been proposed, where BRS(best relay selection) method has been implemented. EM (Exception Maximum) algorithm is used for BRS. The proposed system has been named as EM cooperative system. Performance evaluation has been done for the proposed system over independent Nakagami-m and Rayleigh channels in terms of bit error rate (BER). System performance has been compared with direct transmission, where no algorithm has been used and BRS-DAF cooperative system [7]. Simulation has been done using MATLAB. According to the results, the proposed EM cooperative system proves to be the superior one. EM cooperative system achieves higher spectral density and the desired BER at lower SNR values as compared to the direct transmission and BRS-DAF cooperative. Read More...

Fault Detection & Correction in AES Algorithm for Satellite Communication
-Sachin Kumar ; Sweety Ahlawat
The advanced encryption standard (AES) is the important published cryptographic algorithms. Many computations cycles is required in AES algorithm. AES uses four operations in different rounds such as sub bytes, shift rows, mix columns and additional key round transformations. In military satellites, security is essential. In satellite fault tolerance is very important. Due to radiation fault is induced in the on board electronic systems such as memories, processors etc. before sending the data to ground faults must be detected and corrected. If ground station receives faulty data the users request for data retransmission. Due to radiation, single bit flips called single event upsets (SEU) is induced in satellite on board electronic devices.To avoid faulty data transmission to ground station a unique fault tolerant model is proposed in this thesis. In this paper five modes such as CBC ,OFB,CTR,CFB, and ECB is presented. In this paper we observed that single bit errors can propagate from one block to other blocks depending on AES modes. A single bit corrupts one block of da ta in ECB,CFB,CTR and CBC modes and on the other hand in OFB a single bit corrupts whole data starting from the point. Hence for satellite communication OFB mode is not used. Read More...

Virtual Machine Placement using Enhanced Scheduling and Load Rebalancing using Hybrid Algorithms based on Multi-Dimensional Resource Characteristics in Cloud Computing Systems
-T. Thiruvenkadam ; P. Kamalakkannan
VM placement is defined as the process of mapping the VM requests to the PMs, according to the availability of resources in these hosts. In this paper we present an efficient Virtual Machine Placement System called VMP-LR consists of three main components. First, the Resource Request Handling Component creates VM queues for each data centre using Queuing Algorithm based on Multi-dimensional Resource Characteristics. Second, the VM placement Component uses traffic and load aware Scheduling Algorithms to map VMs to PMs efficiently. These algorithms are also fine tuned to efficiently handle high, medium and low resource requests. Third, Load Monitoring Component performs monitoring the VMs periodically in terms of the selected resources and when usage of the PM drops below a threshold, performs rebalancing using an algorithm. This algorithm is based on ant colony optimization and can avoid over and under utilization of resources. All these components are interconnected and will be monitoring continuously by the VM manager. The proposed VMP-LR was deployed on an open source simulation framework called CloudSim. In order to analyze the efficiency of the proposed algorithms, several experiments were conducted and the results were compared with existing conventional solutions. The proposed algorithm utilizes minimum number of physical servers for hosting the set of VMs, which also reduces the energy consumption of the datacenter and it achieved high resource utilization rate by the way of using minimal number of physical servers.

-Pawan Detwal ; Ibrahim H.Shah; Raghvendra Singh Bhadoriya; Dilip Muchhala; Dimpesh Silarpuriya
Exhaust gas recirculation (EGR) system is one of the post processing techniques and, it is widely used to meet emission standards. And it has been considered as the most effective means to reduce NOx emission from diesel engine. EGR cooler is a simple heat exchanger in which exhaust gas is cooled by coolant from engine itself. Our objective is to enhance the effectiveness of shell and tube type heat exchanger; So that exhaust gas recirculated will be cooled in this way combustion chamber temperature will be lowered & it reduces NOx emission. Therefore we create different models 1,2,3,4. Model-1 is simple shell and tube type and simulates its result on ANSYS by fluent 16.0 (Academic) solver. Then in model-2 we replaced simple tubes by internally rectangular finned type circular tube and get increased effectiveness of the same cooler. And in the model-3, we replace the plane tube in same model by spiral (rectangular cross-section) finned tube, and the Model-4, we replace simple tubes by Dimpled type tubes. Now compare all the four models by their effectiveness, and suggest to use most effective Model-4 among them. So the comparisons were made between shell & finned tube EGR cooler and shell & Dimpled tube type EGR cooler. And we predict the NOx emission for different EGR rate for our most effective Model i.e. Model-4 (Dimpled-tube). Read More...

-Y. V. N. Vasavi ; Mr. K. Ashok Reddy
Glaucoma is a continual disorder which if now not detected in early stages can lead to permanent blindness. The scientific approaches utilized by ophthalmologists like HRT and OCT is high priced and time ingesting. As a result, there is a need to strengthen automated computer aided system which is able to become aware of glaucoma effectively and in much less time. Optic disk and optic cup are prime aspects which help in diagnosing glaucoma. For that reason, proper segmentation of optic disk and optic cup performs an major position in detecting the sickness. On this paper an adaptive threshold based approach which is impartial of photo great and invariant to noise is used to phase optic disk, optic cup, Neuroretinal rim and cup to disk ratio is calculated to screen glaucoma. Another ocular parameter, rim to disk ratio is also considered which in mixture with CDR gives extra reliability in picking glaucoma and makes the procedure extra robust. Extra an SVM classifier has been used to categorize the pixel as glaucomatic or non glaucomatic. The experimental outcome acquired is compared with the ophthalmologist and is discovered to have excessive accuracy of 90%.

Dynamic Anomaly based System for Real Time Intrusion Detection
-Sanju Sandhu ; Dinesh Kumar
As we all know a simple firewall can no longer provide enough scrutiny as in the past. Today's data arrangements in power and business sectors are dispersed whose necessitation requires the use of multiple systems, both proactive and reactive. The premise behind intrusion detection systems is simple: Use a set of agents to filter both network traffic and look for the “signatures†of known network attacks. In this work we have focus on Simple and Hybrid ANN based approach for anomaly detection and how Back Propagation Neural Network (BPNN) cab be used for anomaly detection. One of the novel challenges in the area of IDS detecting unknown or modified attacks because we all know attacks can also have geographically distributed nature. Anomaly based IDS can play a vital role in the field of IDS. We present a Neural Network based technique, which can be used to reduce the false positive in intrusion detection and improve the detection rate in intrusion detection. We will focus on Simple and Hybrid ANN based approach for anomaly detection. This paper will discuss how Back Propagation Neural Network (BPNN) is used for anomaly detection. Read More...

-Hashmi S. Mujahid ; Dr. R. S. Londhe
Precast concrete systems represent an efficient alternative for building construction. The behaviour of a precast system depends on connections and it should be modeled properly in the computational models for analysis and design. The connections between precast members normally constitute the weakest link in the structure, and the satisfactory performance and economy of precast concrete structures depend to a great extent on the proper selection and design of the connections. Due to inadequate guidelines most designers assume the beam-column connection as perfectly hinged connection which leads to unexpected behaviour of the structure. In this paper an attempt is made to resolve this problem by considering the connection as semi-rigid i.e. the actual behavior of connection is modeled discretely to allow limited rotation at the joint. The beam-column connection is allowed with an amount of rotation in accordance with experimental work presented in research papers. The complex behavior of beam-column sub-assembly is counteracted using frame elements with linear links. A 4-storey building is modeled with in SAP2000 and compared with the monolithic building for linear static and dynamic analysis. The models are subjected various earthquake Time Histories i.e. Bhuj, Parkfield, and El Centro so as to cover all the parameters. The results of Top Displacement, Base Shear and Storey Drift are compared for the four models. It concludes that the Top displacement and Storey Drift increases whereas Base Shear decreases for precast building as compared to monolithic RCC structure. Read More...

-Sunitha Joteppagol ; Ms. Sujata.M.Bagi
To achieve ZCS for both power switches and rectifier diodes LCC resonant converter with inductive ï¬lter working in discontinuous current mode (DCM) can be used, as it is suitable for high power, low voltage, high current power supplies. But when voltage varies or load changes this DCM LCC resonant converter with inductive filter might work in different operating modes. To overcome from this problem this paper derives mode boundary map. On the basis of mode boundary map, operating mode of converter can be determined and optimal design process is proposed and set of optimal and normalized converter parameters is determined which can be easily converted into real parameter according to the converter specification.

Analysis of Transonic Flow over Airfoil using CFD for Gas Turbine Blades
-Kushal Gandecha ; Kalpit P. Kaurase
Aerofoil plays a vital role in performance of the gas turbine as they are the key component of the gas turbine blade. The aerofoil is the characteristic design criterion which helps to generate the whole blade on its profile. The various design parameters such as chord length, chamber position, value of chamber, blade thickness; all helps to develop a unique blade profile which will perform better for the given operating condition. Since objective of a gas turbine is to generate the optimum rotation by utilizing the gas stream coming up to it thus the objective while selecting the aerofoil will be to select the aerofoil with maximum value of lift to drag ratio. Also in case of transonic flow the location of shock also plays important role as it will cause losses and various functional problems associated with flow process. As gas turbine operates in transonic zone condition thus selecting a suitable aerofoil for such condition is a important part. Thus in this work we have selected some suitable well defined aerofoil for national adversary of aeronautical community series. Which are being compared with REA2282 aerofoil thus we can select the optimum aerofoil for our purpose. Read More...

An Approach for Security Attack over Mobile Ad-Hoc Network using Hybrid Routing Protocol
-Sandeep Agrawal ; Dr. Siddhartha Choubey
MANET (Mobile ad hoc network) is a congregation of mobile nodes that randomly forms the transitory network and it is a network without infrastructure. The security issue in MANET is more intricate when comparison is done with common network for which the intrusion can be done by getting physical way in to the wired link or pass over sanctuary holes at routers and firewalls. MANETs are defenseless to plentiful attacks. This is a self-governing arrangement in which different mobile nodes are associated by wireless links. MANETs cover of mobile nodes those are self-governing for moving in and out over the network. Nodes in MANET can operate as router/host or reciprocally concurrently. MANET often be unwell with security coercion because of it have features like lack of central management, varying topology dynamically, cooperative algorithms, open medium & monitoring, and no noticeable security mechanism. These made this issue as attentive focus by researcher for the MANETs against the sanctuary threats. In this paper we have elaborated about sanctuary distress in MANET and their penalty. We have proposed the use of hybrid routing protocol against the attacks in MANET. Read More...

Wireless Energy Protocol using Multi-Hop Data Transmission to Enhance Lifetime of Network
-Junaid Mushtaq ; Danvir Mandal
Routing is defined as the process of finding the route for data transmission in the network. In wireless sensor network various sensor nodes are present that are used for the sensing, computing and communication. An external mobile sink is present that is used for the communication with the nodes directly. Previously the static sink approach was used but had some limitations so later this was replaced by the mobile sink approach but still the problem of minimizing of the energy consumed and increasing the lifetime of the network exist today. Traditionally various protocols like LEACH, DECC etc. were used. So in this proposed work the VGDRA routing algorithm is enhanced. To resolve the problem of traditional VGDRA problem the event driven based strategy is used for the data transfer, the energy will be only released when it is required. By this the energy consumption of the system decrease and the life time the network is increased The proposed method is considered to be efficient as the energy consumption is minimum and the life time of the network is increased from the results obtained it is observed that the proposed method of routing is an efficient approach for the route selection. Along with this the selection of the Cluster head is done on the basis of the weight value. A comparison is performed between the traditional and the proposed routing algorithm form which it is concluded that the proposed method is efficient and better than the traditional routing algorithm.

Fault Tolerance and Clustering Algorithm in WSN-A Review
-Mandeep Kaur ; Parul Garg
WSN is a wireless sensor network consisting of a large no of sensor nodes. These nodes are deployed in the network for its feature of monitoring. The process of gathering data and communication takes place from nodes to base stations. The base station is the sink to collect all the data. These sensor nodes have some limitations like limited energy in the form of in-built battery, storage capacity. A WSN can go through different types of failure like connectivity, link, node and malfunctions of nodes. WSN should be good at identifying the fault and put it right instead of discarding it. Energy constraint is one of the main problems that occur when sensors are deployed in the environment. So to create a network which consume less energy and has a long lifetime is a challenge. In this paper, fault tolerance (FT) techniques and clustering algorithm is discussed. Read More...

-Pankaj Vilasrao Kawade ; P. V. Kawade; S. L. Chavan; S. G. Ganiger
This experiment will provide method for increasing tube-in-tube exchanger performance. The tube-in-tube heat exchanger is designed to study the process of transfer of heat between two fluids through a solid partition. It will be designed for a parallel flow as well as counter-flow arrangement and the logarithmic mean temperature difference (LMTD) method of analysis is adopted. Water will be used as a working fluid for the experiment. The temperatures of the hot and cold water supplied to the equipment. The parameter required to find out the effectiveness of the heat exchanger will be arranged in this setup such as the inlet and outlet temperature of the hot and cold fluid, flow rate of the fluid power consumption etc. The modified wire mesh tube in tube will be replaced for the ordinary tube in tube so the surface area is increased so maximum heat will exchange from hot side to the cold side. This will be proved by calculation of the LMTD, Heat transfer coefficient and temperature difference. Arrangement will be made such that in one set we can achieve the both parallel and counter flow by simply opening and closing of the valve shown in the process of this whole setup. This set up is used for comparing the Logarithmic mean temperature difference, heat transfer coefficient, the effectiveness and the temperature difference for the modified wire mesh heat exchanger & with the ordinary Heat exchanger.

one of important task in cardiac disease diagnosis is to identify intra-cardiac masses in echocardiogram. Based on Multi-class SVM classifier to identify the difference between the intra-cardiac masses in echo-cardiograph to get good accuracy. First, a region of interest is cropped to define the mass area. Then apply global de-noising by NLM to eliminate the noise without disturbing the original structure. Subsequently, the contour of the mass and it connected mass atrial wall are identified with adaptive color segmentation model. Finally the motion, the boundary as well as the texture features are processed by SVM classifier. Our proposed method gives good accuracy and sensitivity.

Background Modeling and Moving Object Detection
-Miss. Neha Shivajirao Patil ; Dr. S. R. Gengaje
The most challenging task for most object detection applications is to accurately segment foreground from the background under the presence of heavy illumination changes. Moving object detection provides the separation of pixels in the foreground and background. While classifying, it is most important to model background for better results as background may contain some inappropriate data like flickering monitors, swaying trees etc. The proposed work uses a texture based method i.e. Local binary pattern for modeling the background and detecting moving objects. This approach is very robust in terms of gray scale variations, as the LBP operator is invariant to monotonic transformation of gray scale. Major steps involved in proposed system are background modeling, background subtraction and then foreground detection. The proposed work is implemented on MATLAB platform. Read More...

VLSI Implementation of Aging-Aware Reliable Multiplier with Adaptive Hold Logic
-Pravin Tiwari ; Joy Chakravorty
Multipliers are among the most critical arithmetic functional units. The overall performance of the Digital multiplier systems depends on throughput of the multiplier. The negative bias temperature instability effect occurs when a pMOS transistor is under negative bias (Vgs = −Vdd), increasing the threshold voltage of a pMOS transistor and reducing the multiplier speed. Similarly, positive bias temperature instability occurs when an nMOS transistor is under positive bias. Both effects degrade the speed of the transistor and in the long term, the system may be fail due to timing violations. Therefore, it is required to design reliable high-performance multipliers. In this paper, we implement an agingaware multiplier design with a novel adaptive hold logic (AHL) circuit. The multiplier is able to provide the higher throughput through the variable latency and can adjust the adaptive hold logic (AHL) circuit to lessen performance degradation that is due to the aging effect. The proposed design can be applied to the column bypass multiplier. Read More...
