Abstract: This article discusses several core aspects of security system organization which are able to guarantee efficient protection of corporative resources. These resources could be stored in a common case as an internal sub-system. Recently many enterprises prefer to store them in data centres relying on cloud services. Nevertheless which one of these two approaches will be applied strong procedures for corporative information security and personal data protection must be defined. In order to investigate security procedures for accessing and using business information in a corporative system the article deals with formalization of the processes by using data flow diagram and modelling by Petri Nets (PN) apparatus (in the stochastic extension). An analytical evaluation of the results is carried out and calculated assessments for a case study are given.

Abstract: In recent times, communication through the internet has tremendously facilitated the distribution of multimedia data. Although this is indubitably a boon, one of its repercussions is that it has also given impetus to the notorious issue of online music piracy. Unethical attempts can also be made to deliberately alter such copyrighted data and thus, misuse it. Copyright violation by means of unauthorized distribution, as well as unauthorized tampering of copyrighted audio data is an important technological and research issue. Audio watermarking has been proposed as a solution to tackle this issue. The main purpose of audio watermarking is to protect against possible threats to the audio data and in case of copyright violation or unauthorized tampering, authenticity of such data can be disputed by virtue of audio watermarking. For this I propose a Reversible Contrast Mapping (RCM) which is a simple integer transform that applies to pairs of pixels. For some pairs of pixels, RCM is invertible, even if the least significant bits (LSBs) of the transformed pixels are lost. The data space occupied by the LSBs is suitable for data hiding.

Keywords: Watermarking, Audio watermarking, Reversible Contrast Mapping, Least Significant Bits (LSB's).

Abstract: The Map Reduce platform has been widely used for large-scale data processing and analysis recently. It works well if the hardware of a cluster is well configured. However, our survey has indicated that common hardware configurations in small- and medium-size enterprises may not be suitable for such tasks. This situation is more challenging for memory-constrained systems, in which the memory is a bottleneck resource compared with the CPU power and thus does not meet the needs of large-scale data processing. The traditional high performance computing (HPC) system is an example of the memory-constrained system according to our survey. The proposed new MapReduce system, which aims to improve Map Reduce performance using efficient memory management. The parallel multi-buffer technique to balance data production from CPU and data consumption of disk I/O's, which implements the non-blocking I/O. The parallel also caches the final merged files output by Map tasks in memory to avoid re-reading them from disks before transferring them to remote reduce tasks. All Map/Reduce tasks in a physical node run inside the execution engine, and therefore in a multi JVM, which is one of the key architectural differences between multi JVM and Hadoop. A multi-threaded execution engine, which is based on Hadoop but runs in a multi JVM on a node. In the execution engine, we have implemented the algorithm of hyper scheduling to job assignment, such as sequential disk accessing, multi-cache and shuffling from memory, and solved the problem of full garbage collection in the MJVM. We have conducted extensive experiments to compare parallel Mammoth with scheduling algorithm against the native Hadoop platform. The results show that the modified mammoth system can reduce the job execution time by more than 80 percent in typical cases, without requiring any modifications of the Hadoop programs. Given the growing importance of supporting large-scale data processing and analysis and the proven success of the MapReduce platform, the parallel Mammoth system can have a promising potential and impact.

Abstract: Planning and scheduling and delay analysis have become an essential part of any project for the timely and economical completion of the project. A proper construction schedule can be used for different purposes. By using construction schedule to predict project completion, contractors can adjust crew size, shifts or equipment to speed or slow the progress. All the construction projects will vary from each other in size. All the projects have time constraint. Delay in completion of project will increase the overall cost of the project. Small projects can be managed efficiently manually; whereas large projects are not so large projects can be better handled by the use of computers. Many types of software are available with the help of which project management can be done easily. Large quantities of different kinds of resources are also required for execution and the risk is more in the case of projects. So planning and scheduling of activities for construction of big projects is essential. In this study, an effort is made in planning, scheduling and delay analysis updating of various activities, which is done by using MS Project and MS Excel software, manpower of each activity is determined and allocation is done using the software. Labor requirement for each activity is calculated from standards obtained from site. An updated schedule, which helps to finish the project well in time with optimum resources and update helps in delay analysis, is under the scope of this study.

Keywords: Planning, Scheduling, Delay analysis, MS Project.

Abstract: Energy and Exergy analysis of an Air-Conditioning plant which is running for the last four and half year is presented in this paper. This plant is actually a demonstration project installed by Thermax and Ministry of New and Renewable Energy at National Institute of Solar Energy for research purpose. Triple effect vapor absorption chiller is utilized to produce cooling and the input heat is provided by solar energy with the help of parabolic trough collector. Mathematical modeling of vapor absorption chiller is done for formulating the required relations for evaluation. Energy and exergy balance equations of chiller are clearly presented. The results of analysis of chiller shows that the two heat exchangers, (HX I) and (HX II) are the biggest source of exergy destruction, destroying 16.40 % and 8.60 % of exergy respectively. Deviating from the previous published results in literature, absorber is not the component where maximum exergy is destroyed. The components that need to be optimized are the three generators. The COP is also calculated from energy balance and it comes out to be 1.27. Exergetic efficiency of chiller obtained is 9.2 %.

Abstract: Packet dropping attack, which is a crucial issue in networks. Link error and malicious packet dropping are two sources for packet losses. While observing a sequence of packet losses in the network, it is difficult to identify whether the loss is due to link errors or malicious nodes. Packet may be dropped during forwarding of routing information or during data forwarding. Dropping can be due to presents of malicious nodes or due to link error. Hence to improve the detection accuracy, the correlations between lost packets is identified. The proposed method is based on detecting the bitmap between the lost packets over each hop of the path. It provides a truthful and publicly verifiable decision statistics as a proof to support the detection decision. The high detection accuracy is achieved by exploiting the correlations between the positions of lost packets, as calculated from the Audit based elliptic curve cryptography (AECC) which describes the status of each packet in a sequence of packet transmission. Therefore, by detecting the correlations between the lost packets, one can decide whether the packet loss is purely due to link errors, or is a combined effect of malicious drop and link error. Audit node is used to identify the malicious node or not. The Audit management in the WSN is like usually RREQ and RREP message passing between nodes. The energy is used to distinguish between altruism and selfish node.

Abstract: Electric Vehicles [EV] of next generation are pushing the development of new battery technologies. To minimize cost and maximize efficiency, vehicle system should have full usable battery storage capacity. Remarkable progress has been achieved on battery technologies for EVs and HEVs [Hybrid Electric Vehicles]. Battery energy densities have steadily increased, and batteries today can be reliably charged and discharged thousands of times. If designers can effectively exploit these advancements in energy capacity, EVs and HEVs have the potential to be competitive with traditional vehicles in terms of cost, reliability, and longevity. An important consideration for the battery pack monitoring system is the communications interface. For communication within a PC board, common options include the Serial Peripheral Interface (SPI) bus and Inter-Integrated Circuit (I2 C) bus. Each has low communications overhead, suitable for low interference environments. Another option is the Controller Area Network (CAN) bus, which has widespread use in vehicle applications. The CAN bus is very robust, with error detection and fault tolerance, but it carries significant communications overhead and high materials cost. While an interface from the battery system to the main vehicle CAN bus may be desirable, SPI or I2C communications can be advantageous within the battery pack.

Abstract: One fundamental issue in today On-line Social Networks (OSNs) is to give users the ability to control the messages posted on their own private space to avoid that unwanted content is displayed. Up to now OSNs provide little support to this requirement. To overcome this problem, we propose a system allowing OSN users to have a direct control on the messages posted on their walls. This is achieved through a flexible rule-based system, that allows users to customize the filtering criteria to be matter-of-fact to their walls, and a Machine Learning based soft classifier automatically labelling messages in content-based filtering.

Abstract: In this paper, the wear behavior of Aluminium Metal Matrix Composite with Silicon Carbide used for Brake Pads under Dry Friction Condition is to be studied. The percentage of silicon carbide is varies from 4 to 13 in four steps. The tribological behavior of composites was investigated by pin on disc apparatus. Percentage reinforcement, load, sliding speed and sliding distance were taken as the process variable. The parameters are set for different levels and in optimum possible combination by Taguchi experimentation design array. Wear rate is obtained as a response of experimentation and then further analyzed in design expert software. Parametric relation is developed in the form of equation for each material composition. At the end all three materials are compared on the basis of wear rate and coefficient of friction. As graphical representation is the most user friendly way of interpretation of statistical data, three-dimensional graphs comparing wear rate of all three materials simultaneously under the influence of individual parameters namely load, sliding distance and sliding velocity are given in results. Conclusions of the present work are, as load and sliding distance increases wear rate also increase, and as the velocity of sliding increases wear rate slightly decrease. Material composition is the major factor influencing the wear rate of brake pad, as the wear rate of all four material are different which is shown in paper in tabulated form. The increase in percentage of silicon carbide increases the wear resistance.

Keywords: wear rate, aluminium metal matrix, SiC, pin on disc apparatus, and design expert software.

Abstract: In the recent years, heat transfer augmentation techniques plays an important role for improving the rate of heat transfer without affecting the overall performance of the system. Enhanced heat transfer surfaces are mostly used in heat exchanger, air conditioner, refrigeration system, chemical reactor. The high cost of energy and material has resulted in an increased effort aimed at producing more efficient heat exchange equipment. Augmentation techniques increase forced convective heat transfer by reducing the thermal resistance in a heat exchanger. These techniques are broadly classified as passive, active and compound techniques. Passive techniques, where inserts are used in the flow path to intensify the heat transfer, are advantageous when compared with active techniques, because the insert manufacturing process is simple and these techniques can be easily employed in an existing heat exchanger. In this paper, emphasis is given to work dealing with round pipe conical ring inserts. Conical ring inserts are generally more efficient in the turbulent flow compared to the laminar flow.

Keywords: Augmentation techniques, forced convective heat transfer, conical ring insert, heat transfer coefficient.

Abstract: AA6082 aluminium alloy was reinforced with 5wt% of TiB2 particles using the Flux Assisted Technique (FAS) using inorganic K2TiF6 and KBF4 salts at 800ºC. The evolution of the microstructure and the grain size effect was investigated by varying the reaction time of the salt with aluminium alloy melt. The reaction time was varied from 0-90min in steps of 30min. At lower reaction time the presence of more number of Al3Ti, AlB2 particles were predominantly observed. As the reaction time increased the formation of more number of TiB2 particles in the matrix alloy was evident. At lower reaction time of 30min the grain size of the composite decreased compared to the matrix alloy due to the presence of more number of effective Al3Ti nucleant particles, whereas at higher reaction time increase in grain size was observed due to the absence of Al3Ti particles, which dissociates to form TiB2 particles.

Abstract: Frequent item set mining (FIM) is one of the most fundamental problems in data mining. In this paper, a differentially private FIM algorithm is given which can not only achieve high data utility and a high degree of privacy, but also offer high time efficiency. A differentially private FIM algorithm is based on the FP-growth algorithm, which is referred to as PFP-growth. The PFP-growth algorithm consists of two main phases, preprocessing phase and mining phase. In the preprocessing phase, a smart splitting method is used to transform the database. In the mining phase, to cover the information loss caused by transaction splitting, we used a run-time estimation method to estimate the actual support of item sets in the original database. Through formal privacy analysis, we show that our PFP-growth algorithm is differentially private. After this one-to-many data linkage method is used to link different item sets and this method is based on One Class Clustering Tree (OCCT).

Abstract: Mobile Ad-hoc system framework (MANET) is a self decision plan of flexible centers related by remote associations. Each center point acts as an end system and in addition a change to forward packs. The centers are permitted to move about and create themselves into a framework. These center points change position a significant part of the time. The essential classes of routing protocol are Proactive, Reactive and Hybrid. A Reactive (on-interest) routing strategy is a predominant coordinating grouping for remote uncommonly selected directing. It is a decently new directing rationale that gives a versatile response for the most part broad framework topologies [1]. The framework takes after the prospect that each center tries to decrease sending in order to guide overhead coordinating packs at whatever point a correspondence is inquired. In this paper an endeavour has been made to analyze the execution of two conspicuous on demand responsive routing protocol for MANETs: Ad hoc On Demand Distance Vector (AODV) and Dynamic source routing protocol (DSR). Here we are analysing and comparing AODV and DSR protocol in TCP and UDP environment by varying number of nodes. we will analyse the Throughput, End-To-End Delay and Packet delivery ratio. We will analyse the result for both the protocols and compare them which protocol best suit in which environment.

Abstract: The security of the E-mail messages is an important issue; no such security is supported by the Internet standards. To overcome the attacks and to improve the security a new model is used which is "Secure Mail using Visual Cryptography". In this method the messages have to be transmitted is converted into a gray scale image. Then (2, 2) visual cryptographic shares are generated from the gray scale image. The shares are encrypted using A Chaos-Based Image Encryption Algorithm using Wavelet Transform and authenticated using Public Key based Image Authentication method. One of the shares is send to a server and the second share is send to the recipient's mail box. The two shares are transmitted through two different transmissions medium so man in the middle attack is not possible. If an adversary has only one out of the two shares, then he has absolutely no information about the message. At the receiver side the two shares are fetched, decrypted and stacked to generate the grey scale image. From the grey scale image the message is reconstructed .But in this can see an outline of image from one share. And also Encryption techniques used for encrypting textual data does not work with images, so separate encryption techniques are required for images. So, we proposed here a new scheme for image encryption which is helpful for end to end secure transmission of digital information on open network using explosive block displacement followed by inter-pixel.

One of the fundamental concerns is that of Rogue Access Points (RAP). These security threads which bring about extreme damage to hierarchical information and assets could be because of inside or outer cause. Access point could be one reason which might permit attackers to break the security of authoritative system and permit them to get to sensitive data from system. The access points deployed without clear and definite permission from network administrator are called unauthorized, fake or rogue access point. There are numerous chances of presences of RAP in LAN. Rogue Access Points (RAPs) is one of the primary security threads in current framework circumstance, if not honestly dealt with in time could lead from minor framework issues to genuine system network failure. We propose a Multi-Agent Sourcing Based Methodology, which recognizes Rogue Access Point as well as totally eliminates it. This Methodology has the going with phenomenal properties: (1) it doesn't require any particular equipment or hardware; (2) the proposed calculation identifies and totally disposes of the RAPs from system; (3) it provides a cost-effective solution. The proposed procedure can block RAPs and also remove them from the systems.

Abstract: Box culverts are the structures constructed below highways and railways to provide access to the natural drainage across them. The opening of the culvert is determined based on the waterway required to pass the design flood, whereas the thickness of the culvert section is designed based on the loads applied on the culvert. Culverts and bridges often serve the same purpose; however, they differ on the size of the structure. Box culverts are ideal for flows where hydraulic head is limited. For an equivalent waterway area to circular pipes, box culverts can be configured to have less impact on upstream water levels and downstream flow velocities than equivalent pipe structures. This report devotes to the box culverts constructed in reinforced concrete having different aspect ratios. The box culverts are analyzed for varying cushion and no cushion loading. The main emphasis is given to the behavior of the structure under the types of loading as per IRC codes and their combinations top produce worst effect of loading for safe structure. Comparison and conclusion are made on the basis of maximum bending moments shown for different loading cases.

Abstract: The vehicular ad-hoc networks are described by high mobility of nodes, which resulting in regular and rapid changes in the network topologies. A trust based framework is proposed for safe and reliable information dissemination in vehicular networks. Group Based Receiver-Driven Protocol divides the network into clusters or groups, where nodes are grouped using the same search query like the same direction or same destination route, or so on. Each cluster has a cluster head (Group Leader), its task is to manage communication processes inside, and to outside its cluster. The proposed scheme has the benefit of using real-time road environment to figure a better route and at the same time, the information source can be correctly authenticated.

Abstract: The water discharge from the canal depends on the various canal parameters viz. upstream water level, downstream water level, canal dimensions, etc. For the correct water distribution, the upstream and downstream water levels need to be maintained properly. Continuous discharge of water at constant rate is can be achieved by keeping the difference between upstream and downstream water levels constant. The canal gate opening needs to be corrected according to the changes in the upstream water level, desired water discharge, flow rates, etc. The Proportional Integral Derivative (PID) control algorithms are robust and efficient to achieve zero steady state error. Thus in order to maintain the correct the gate position, PID algorithm can be used. A PID algorithm based embedded system is implemented to maintain the upstream water level in the canal at constant desired level. The implemented system maintains the desired upstream water level within the acceptable tolerance limits.

Keywords: Upstream water level, downstream water level, canal dimension, PID algorithm.

Abstract: Every complex system interacts with its environment to perform number of tasks within acceptable tolerances. Any change in performance or unacceptable result is treated as fault or error. The Fault Detection and Diagnosis (FDD) technique is used to determine such faults or errors, to find the root cause and to take necessary actions to prevent such error to occur in the system. This will protect the system from damage and will give maximum throughput. Fault Dependency D-matrix is one such approach to find faults at different levels which consists of dependencies observed and actual failure symptoms associated with the system. But in practical it's difficult to construct d-matrix . In this paper we define a text mining method based on ontology for automatically constructing D-matrix by mining thousands of unstructured data. In this method we first construct the fault diagnosis ontology consisting of concepts and relationships usually observed and examined in the fault diagnosis domain. Then we use the text mining algorithms that make use of the ontology concept to develop the D-matrix. Then we use the text mining algorithms that make use of the ontology concept to develop the D-matrix. Next Graph is created for every D Matrix & from all generated graphs similarity graph is created.

Abstract: One of the important assumptions of data is the normality on which most of the statistical model and procedures rely on regarding the validity of given data hypothesis. Assuming the normality assumption blindly may affect the accuracy of inferences and estimation procedures. As observed, the collected data from real field are not always follow the normality assumption. So, data must be verified with adequate statistical test before used. There are various kinds of goodness of fit tests in literature. Some of them are special purpose tests, so that they are suitable and perform well for some special situations. Others are omnibus tests that are applicable to general cases. Most commonly used tests are Pearson's chi-squared test and EDF (empirical distribution function) tests, such as Kolmogorov-Smirnov, Cramer-Von-Mises and Anderson-Darling test. The chi-squared test is easy to use but they are generally less powerful than EDF tests. In this paper we want to study the performance of twelve different tests for normality including the above mentioned tests. Considering various sample sizes and different alternative hypotheses results are obtained and displayed in different tables. Finally, discussions are made on the basis of the results.

Abstract: The Railway network is the world's biggest transport network. There have been many accidents occurs in the railway network system. Most of the accidents occurred due to the collision between the trains and human negligence The proposed system is used to predict that kind of collision between trains and prevents them from occurring collision and accident .Railways are the convenient, reasonable and popular node of transport in almost all major cities of not only in India but also all over the World. The major reason for railway accidents is collision of trains on the same track or near crossing. It is very difficult to stop such collisions due to speed of moving trains, which is needs a lead distance to stop. The primary goal of our train collision detection system is to identify possible train collision ahead of time and to report these to the main control room or driver before collision happens. Train Collision Avoidance System includes the microcontroller ARM Cortex TM4C123GH6PM which controls the whole operation of the system. In this the train tracks in railway network are given distinct track numbers/track ids which are read by RFID reader. If two trains are travelling on the same track then system sends SMS through GSM network to the authorized person to take appropriate action. In areas where GSM network is poor then also the system avoid collision by using RF Module. Wherever at crossing LDR sensor and microcontroller unit take appropriate action if obstacle can be observed.

Abstract: Traffic classification is an automatic method that categorizes electronic network traffic per varied parameters into variety of traffic categories. Many supervised classification algorithms and unsupervised clump algorithms have been applied to reason web traffic. Traditional traffic classification strategies embody the port-based prediction strategies and payload-based deep scrutiny strategies. In current network environment, the traditional strategies suffer from variety of sensible issues, such as dynamic ports and encrypted applications. In order to enhance the classification accuracy, Support Vector Machine (SVM) and Naïve Bayes estimator is projected to reason the traffic by application. In this, traffic flows are represented mistreatment the discretized applied math options and flow correlation data is modelled by bag-of-flow (BoF). This methodology uses flow statistical feature based mostly traffic classification to boost feature discretization. This approach for traffic classification improves the classification performance effectively by incorporating correlated data into the classification method. The experimental results show that the proposed theme will come through far better classification performance than existing progressive traffic classification strategies.

Abstract: Message authentication is used to stop unauthorized and corrupted messages from being in Wireless Sensor Networks (WSNs). Message authentication schemes have two approaches: public-key based and symmetric-key based approaches. To address these issues, this research work proposes a scalable authentication scheme based on Global Elliptic Curve Cryptography (GECC). The proposed scheme allows any number of messages to transmit in intermediate node authentication. In addition, the GECC scheme can also provide message source privacy and multiple base station environments. The proposed GECC scheme enables the intermediate node authentication so that all corrupted message can be detected and dropped.

Abstract: Energy savings optimization becomes one of the major concerns in the wireless sensor network (WSN) routing protocol design, due to the fact that most sensor nodes are equipped with the limited non rechargeable battery power. In this paper, we focus on minimizing energy consumption and maximizing network lifetime for data relay in one-dimensional (1-D) queue network. Following the principle of opportunistic routing theory, multihop relay decision to optimize the network energy efficiency is made based on the differences among sensor nodes, in terms of both their distance to sink and the residual energy of each other. Specifically, an Energy Saving via Opportunistic Routing (ENS_OR) algorithm is designed to ensure minimum power cost during data relay and protect the nodes with relatively low residual energy.

Abstract: The control of chemical reactor is one of the most challenging problems in control process. A Continuous Stirred Tank Reactor (CSTR) is the heart of many processes, its stable and efficient operation is important to the success of an entire process. The CSTR is one of the optional machineries available to mimic and maintain the deep sea conditions such as pressure, temperature, pH etc in the laboratory to study environmental effects. This paper presents the design of suitable conventional controller and tuning methods to optimize the system performance for a hyperbaric reactor system. In environmental CSTR the control of temperature is an absolute challenge due to strong on-line non linearity. The suitable control strategy was explored here to develop the environmental CSTR system for deep sea applications using real time on-line open loop temperature curve. The First Order Plus Dead Time (FOPDT) process model was chosen to derive transfer function from real time on-line system curve at atmospheric pressure and 310C temperature condition. Simulation and result comparison is carried out using MATLAB &SIMULINK. Different conventional controllers are examined to optimize the temperature control for environmental CSTR system. The simulation result on the environmental CSTR system is presented to show efficiency of various controllers.

Abstract: The stability of an artificial cement less femoral stem depends on its fit within the femoral cavity. In this study, a cement less hip joint stem was designed based on the anthropometric data of 98 femurs of patients of Indian (Asia) origin. The design was manufactured on a standard CNC milling machine and was made of Ti6Al4V. In vitro stability studies were carried out using standard test protocol incorporating standard potting cement, a selective laser sintered (SLS) femur and a dry cadaveric femur. The micro-motion of the stem was measured using LVDTs attached at various locations along the designed implant. The entire setup was placed in an Instron test machine with an applied static axial load of 2500N. For the test in potting cement, the strains ranged between 320 and 1211 ?m over the measured sites. Strain on the lateral side was found to be less for the new design as compared with a conventional design, while on the medial side it was almost the same for both. The maximum micro motion for the stem-dry femur construct was found to be 1800 ?m whereas for the stem-SLS femur combine, it was found to be 380 ?m. The finite element models developed were found to closely match the behavior of the stem-potting cement construct and stem-SLS femur.
