Provider Aware Anonymization Algorithm for Preserving M -
Privacy
Provider Aware Anonymization Algorithm for Preserving M -
Privacy
Abstract: In this paper, we consider the collaborative data publishing problem for anonymizing horizontally partitioned
data at multiple data providers. We consider a new type of "insider attack" by colluding data providers who may
use their own data records (a subset of the overall data) in addition to the external background knowledge to
infer the data records contributed by other data providers. The paper addresses this new threat and makes several
contributions. First, we introduce the notion of m-privacy, which guarantees that the anonymized data satisfies a
given privacy constraint against any group of up to m colluding data providers. Second, we present heuristic
algorithms exploiting the equivalence group monotonicity of privacy constraints and adaptive ordering
techniques for efficiently checking m-privacy given a set of records. Finally, we present a data provider-aware
anonymization algorithm with adaptive m- privacy checking strategies to ensure high utility and m-privacy of
anonymized data with efficiency. Experiments on real-life datasets suggest that our approach achieves better or
comparable utility and efficiency than existing and baseline algorithms while providing m-privacy guarantee.

Railway Ticket Counter Problem With STM
Railway Ticket Counter Problem With STM
Abstract: The past few years have marked the start of a historic transition from sequential to parallel computation. The necessity to write parallel programs is increasing as systems are getting more complex while processor speed increases are slowing down. Current parallel programming uses low-level programming constructs like threads and explicit synchronization using locks to coordinate thread execution. Parallel programs written with these constructs are difficult to design, program and debug. Also locks have many drawbacks which make them a suboptimal solution. One such drawback is that locks should be only used to enclose the critical section of the parallel-processing code. If locks are used to enclose the entire code then the performance of the code drastically decreases..
Key words: Parallel Programming; Multiprocessing; Locks; Transactions; Software Transactional Memory .

Abstract: Congestion Management is one of the major tasks performed by system operator to ensure the operation of transmission system within operating limits. In the emerging electric power market, the congestion management becomes extremely important and it can impose a barrier to the electricity trading. In the present paper, a concept of transmission congestion penalty factors is developed and implemented to control power overflows in transmission lines for congestion management. Here we presents a Re-dispatch methodology for cost of transmission network to its user. The transmission price computation considers the physical impact caused by the market agents in the transmission network. The paper includes case study for IEEE 5 bus power system.
Key words: Optimal power flow, Congestion Management.

Thermodynamic Analysis of a Cascade Refrigeration System Based On Carbon Dioxide and Ammonia
Abstract: Thermodynamic analysis of a cascade refrigeration system that uses carbon dioxide-ammonia (R744-R717) as refrigerant is presented in this paper to determine the optimum condensing temperature of the cascade condenser at given design parameters, to maximize the COP of the system. The design and operating parameters considered in this study include (1) condensing, sub cooling, evaporating and super heating temperatures in the ammonia (R717) high-temperature circuit, (2) temperature difference in the cascade heat exchanger, and (3) evaporating, superheating, condensing and sub cooling in the carbon dioxide (R744) low-temperature circuit. A multilinear regression analysis was employed in order to develop two useful correlations for maximum COP, and optimum condensing temperature.

Design & Performance Analysis of DG-MOSFET for Reduction of Short Channel Effect over Bulk MOSFET at 20nm
Design & Performance Analysis of DG-MOSFET for Reduction of Short Channel Effect over Bulk MOSFET at 20nm
Abstract: An aggressive scaling of conventional MOSFETs channel length reduces below 100nm and gate oxide thickness below 3nm to improved performance and packaging density. Due to this scaling short channel effect (SCEs) like threshold voltage, Subthreshold slope, ON current and OFF current plays a major role in determining the performance of scaled devices. The double gate (DG) MOSFETS are electro-statically superior to a single gate (SG) MOSFET and allows for additional gate length scaling. Simulation work on both devices has been carried out and presented in paper. The comparative study had been carried out for threshold voltage (VT), Subthreshold slope (Sub VT), ION and IOFF Current. It is observed that DG MOSFET provide good control on leakage current over conventional Bulk (Single Gate) MOSFET. The VT (Threshold Voltage) is 2.7 times greater than & ION of DG MOSFET is 2.2 times smaller than the conventional Bulk (Single Gate) MOSFET.
Key words: DG MOSFET (Double Gate Metal oxide Field Effect Transistor), Short Channel Effect (SCE), Bulk (Single Gate) MOSFET.

Experimental Study, Simulation and Model Predictions of Recycled PET Strip-Reinforced Concrete Flexion Members
Experimental Study, Simulation and Model Predictions of Recycled PET Strip-Reinforced Concrete Flexion Members
Abstract: This study presents results from a theoretical-experimental program of beams partially pre-stressed made with continuous recycled PET strip-reinforced concrete (plain concrete strength of 20 MPa). These studies mainly attempted to determine the stripinfluence in altering the flexural strength at first and final crack. Also the load-deflection, ductility, energy absorption capacity of the beams are observed and the studies can be used in predicting the flexural behavior of longitudinally reinforced concrete. The model theory assumes that concrete has a tensile load capacity different from zero, characterized by a uniaxial tensile stress-strain diagram. The need for non-linear geometric and the material models imply the use of numerical methods such as the finite element method; so that, a finite element analysis of reinforced concrete beam with strips-reinforced plastic is performed. The obtained results were compared with computer analysis and experimental data to corroborate the validity of the suggested method, showing that the theory also predicts correctly the post-cracking creep deformation.

CFD Studies of Split Injection on the Combustion and Emission Characteristics in DI Diesel Engine
Abstract: In this study, the effect of split injection on the combustion and emissions in DI diesel engine is investigated using CFD tool .One of the important problems in reducing pollutant emission from diesel engines is trade-off between soot and NOx. Split injection is one of the most powerful tools that decrease soot and NOx emissions simultaneously. Split injection is defined as splitting the main single injection profile in two or more injection pulses with definite delay dwell between the injections. A four-stroke, single cylinder, diesel engine was taken into consideration at constant speed conditions . A model was developed for comprehensive predictions and assessments for variations in combustion phenomenon for DI diesel engines . By using the finite volume method the design and analysis of combustion chamber,emission characteristics were studied. The results of the split injection were compared with single injection and the optimum case of split injection was observed.

CFD Studies of Combustion in Direct Injection Single Cylinder Diesel Engine Using Non-Premixed Combustion Model
CFD Studies of Combustion in Direct Injection Single Cylinder Diesel Engine Using Non-Premixed Combustion Model
Abstract: In this study the simulation process of non-premixed combustion in a direct injection single cylinder diesel engine has been described. Direct injection diesel engines are used both in heavy duty vehicles and light duty vehicles. The fuel is injected directly into the combustion chamber. The fuel mixes with the high pressure air in the combustion chamber and combustion occurs. Due to the non-premixed nature of the combustion occurring in such engines, non-premixed combustion model of ANSYS FLUENT 14.5 can be used to simulate the combustion process. A 4-stroke diesel engine corresponds to one fuel injector hole without considering valves was modeled and combustion simulation process was studied. Here two types of combustion chambers were compared. Combustion studies of both chambers:- shallow depth and hemispherical combustion chambers were carried out. Emission characteristics of both combustion chambers had also been carried out. The obtained results are compared. It has been found that hemispherical combustion chamber is more efficient as it produces higher pressure and temperature compared to that of shallow depth combustion chamber. As the temperature increases the formation of NOx emissions and soot formation also get increased.

Fresh Water Augmentation and Salinity Management in Kuttanad
Fresh Water Augmentation and Salinity Management in Kuttanad
Abstract: The Thanneermukkam bund was constructed to resolve the salinity problems faced by the farmers of Kuttanad; though it could reduce the problems to a large extend it had many ill effects such as water pollution, spread of aquatic weeds and other flora and fauna related problems. The main objective is to reduce the salinity level in Vembanad Lake during summer season that is during the closure period of Thanneermukkam Bund (TMB). The problem is solved efficiently by adapting following methods (1) water is taken from Muvattupuzha River, and conveyed through a regulator to Kuttanad region during summer season to dilute the water and keep the salinity below 2ppt and (2) water is collected in the pazhnilam before the closure of TMB and pumped out into Lake surrounding at times of acute shortage. The design of the regulator, its location and working is also discussed along with the various management techniques to be adopted in Kuttanad for effective implementation of the project. A proposal for management of water quantity and salinity for the natural water system of Kuttanad is developed.

Microcontroller–Based Modified SEPIC Converter for Driving
Lamp with Power Factor Correction
Microcontroller–Based Modified SEPIC Converter for Driving
Lamp with Power Factor Correction
Abstract: A methodological study of electronic ballast for electrode less lamps including design and development issues is
presented in this paper. The ballast is intended to feed a 300 W ultra violet lamp at 100 kHz with dimming
feature. The proposed topology is composed of a Single-Ended Primary Inductance Converter (SEPIC), used as
power factor correction (PFC) stage, integrated with a resonant half-bridge inverter, used as lamp power control
(PC) stage. The integration of both stages is proposed in this paper, in order to reduce the number of active
switches, as well as to simplify the required driving and control circuitry for this application. The implemented
topology attained very high power factor (0.9982), and low line current total harmonic distortion (THD)
(1.86%), without using electromagnetic interference (EMI) filter, while the measured efficiency was 90% at
nominal lamp power.

Development And Implementation Of OFDM Transceiver For WLAN Applications
Development And Implementation Of OFDM Transceiver For WLAN Applications
Abstract: Multi-Carrier modulation is a technique for data transmission by multiplexing a low bit-rate data streams to modulated carriers into signal Wideband Carrier. Multi-Carrier transmission has a lot of useful properties such as delay-spread tolerance and spectrum efficiency that encourage their use in untethered broadband communication. OFDM is becoming the chosen modulation technique for wireless communications. OFDM is a multi-carrier modulation scheme with densely spaced sub-carriers that has gained a lot of popularity among the broadband community in the last few years. OFDM can provide large data rate with sufficient robustness to radio channel impairments. OFDM works on the principle of Orthogonality. The orthogonality between subcarriers which is at the core of OFDM modulation requires a perfect synchronization. OFDM has properties like high spectral efficiency, Resiliency to RF interference and Lower multi-path distortion. This work is concentrated in implementing both transmitter and receiver using Matlab software and also to verify whether the transmitted data is obtained at the receiver side. As we are using the OFDM technique we will be having bandwidth efficiency when compared to the normal FDM technique.
Key words: Digital Baseband modulation, IQ modulation, Orthogonality, OFDM, PAPR.

Privacy Preservation and Restoration of Data Using Unrealized Data Sets
Privacy Preservation and Restoration of Data Using Unrealized Data Sets
Abstract: In today's world, there is an improved advance in hardware technology which increases the capability to store and record personal data about consumers and individuals. Data mining extracts knowledge to support a variety of areas as marketing, medical diagnosis, weather forecasting, national security etc successfully. Still there is a challenge to extract certain kinds of data without violating the data owners' privacy. As data mining becomes more enveloping, such privacy concerns are increasing. This gives birth to a new category of data mining method called privacy preserving data mining algorithm (PPDM). The aim of this algorithm is to protect the easily affected information in data from the large amount of data set. The privacy preservation of data set can be expressed in the form of decision tree. This paper proposes a privacy preservation based on data set complement algorithms which store the information of the real dataset. So that the private data can be safe from the unauthorized party, if some portion of the data can be lost, then we can recreate the original data set from the unrealized dataset and the perturbed data set.
Index Terms: Data mining, Privacy Preserving Data Mining (PPDM), Decision Tree, Decision Tree Learning, ID3 algorithm, C4.5 algorithm, Unrealized Dataset, Data Perturbation, Dataset Complementation.

A Study on Physico-Chemical Characteristics of Borewell Water In Sugar Town, Mandya City, Karnataka State, India
Abstract: Groundwater is a natural resource for drinking water .In addition to the population growth, urbanization and industrialization also extend the demand of water. Providing safe drinking water supply to the ever growing urban and sub-urban population is going to be a challenge to the civil authorities, city planners, policy makers and environmentalists. Groundwater is a major source of drinking water in both urban and rural areas of Mandya. Mandya city is rapidly raising population, changing lifestyle and intense competition among users- agriculture, industry and domestic sectors is driving the groundwater table lower. Besides, discharge of untreated wastewater through bores and leachate from unscientific disposal of solid wastes also contaminate groundwater, thereby reducing quality of fresh water resources.
The present work is aimed at assessing the water quality index for the ground water samples of Sugar town, Mandya city. The groundwater samples of about 40 samples were collected and subjected for a comprehensive physicochemical analysis. The purposes of this investigation are to provide an overview of present ground water quality for the following 12 parameters such as pH, total hardness, calcium, magnesium, chloride, nitrate, sulphate, total dissolved solids, iron, fluoride, alkalinity are to be considered for calculating the WQI. The results are analyzed by WQI method for predicting water quality. Water Quality Index (WQI) is a very useful and effective way for assessing the quality of water. WQI is a very useful tool for communicating the information on overall quality of water.
Key words: Groundwater, Water quality standards, Water quality characteristics, Water quality index.

Adaptive Variable Structure Controller Application to Induction Motor Drive
Adaptive Variable Structure Controller Application to Induction Motor Drive
Abstract: Variable structure control is an adaptive control that gives robust performance of a drive with parameter variation and load torque disturbance. Variable control structure is a robust control scheme based on the concept of changing the structure of the controller in response to the changing state of the system in order to obtain a desired response. The control is nonlinear and can be applied to the linear or nonlinear plant. A high speed switching control action is used to switch between different structures of the controller and the trajectory of the system is forced to move along a chosen switching manifold in the state space. The controller detects the deviation of the actual trajectory from the reference trajectory and corresponding changes the switching strategy to restore the tracking. Prominent characteristics such as invariance, robustness, order reduction, and control chattering are discussed in detail. Methods for coping with chattering are presented. Both linear and nonlinear systems are considered. By using Variable structure controller to control the step change in reference speed and drive system under load torque variations.

Zigbee Based Indoor Campus Inventory Tracking Using Rfid Module
Zigbee Based Indoor Campus Inventory Tracking Using Rfid Module
Abstract: This is a very useful application of RFID (Radio-frequency identification) and is very commonly used in institutes, offices, homes and so on. An RFID system consists of a reader device and a transponder. A transponder or tag has a unique serial number which is identified by the reader. Here RFID has been interfaced with ARM Processor to provide secured access. The relevant messages are also displayed on a 16x2 LCD.RFID automated access for door controls to buildings, departments, rooms, secured closets (wiring, PBX, etc.) and cabinets is very cost effective and secure to use. Many people do not realize how easy it is to implement card access systems such as card access door or doors using RFID readers and RFID Cards or Key fobs for Secured Access Control Management. You can even use smart readers for computer rooms and securing individual computers. RFID tags are categorized as either active or passive. Active tags are powered by an internal battery and are typically read/write,i.e tag data can be rewritten or modified. Passive tags operate without a separate external power source and obtain operating power generated from the reader.

Experimental Study of the Flexural Behaviour of Damaged RC Beams Strengthened in Bending Moment Region with Basalt Fiber Reinforced Polymer (BFRP) Sheets
Experimental Study of the Flexural Behaviour of Damaged RC Beams Strengthened in Bending Moment Region with Basalt Fiber Reinforced Polymer (BFRP) Sheets
Abstract: This paper presents the flexural behaviour of basalt fiber reinforced polymer (BFRP) strengthened reinforced concrete (RC) beams. For flexural strengthening of reinforced concrete beams, total twenty-two beams were cast and tested over an effective span of 900 mm up to failure of the beam under two-point loading. The beams were designed as under-reinforced beams. The beams were bonded with BFRP sheets in single layer and double layers in the bending moment region at the bottom face of the beam. Out of the twenty-two beams two beams were control beams and remaining beams were strengthened after being damaged for various degrees of damage (0 %, 70 %, 80 %, 90% and 100 %). The experimental results show that the beams strengthened show high load carrying capacity.
Key words: Basalt Fiber Reinforced Polymer (BFRP), Bending moment region, Control beam, Reinforced Concrete, Strengthened beam, Ultimate Load carrying capacity.

Effect of Cooking on the Polyunsaturated Fatty Acid and Antioxidant Properties of Small Indigenous Fish Species of the Eastern Himalayas
Effect of Cooking on the Polyunsaturated Fatty Acid and Antioxidant Properties of Small Indigenous Fish Species of the Eastern Himalayas
Abstract: The effect of cooking method on the polyunsaturated fatty acid and antioxidant properties of small indigenous freshwater fish species, Amblypharyngodon mola and Puntius sophore of the Eastern Himalayas were determined. In the raw and fried samples, docosahexaenoic acid was significantly higher (2.907 and 1.167mg/100g) in Amblypharyngodon mola and lowest (0.749 and 0.291mg/100g) were recorded in Puntius sophore. The eicosapentaenoic acid of raw, fried and curried samples of Amblypharyngodon mola were recorded higher. In DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging assay of IC50 value of the raw fish extract were 2.9μg/ml and 1.66μg/ml respectively. The highest antioxidant activity was found in fish curry of Amblypharyngodon mola (0.11μg/ml). It shows that the Maillard reaction product forms the melanoidin during cooking, increases the antioxidant property of the fish curry and also improved the taste.

Channel Estimation Techniques in MIMO-OFDM LTE Systems
Channel Estimation Techniques in MIMO-OFDM LTE Systems
Abstract: There is an increasing demand for high data transmission rates with the evolution of the very large scale integration (VLSI) technology. The multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) systems are used to fulfill these requirements because of their unique properties such as high spectral efficiency, high data rate and resistance towards multipath propagation. MIMO-OFDM systems are finding their applications in the modern wireless communication systems like IEEE 802.11n, 4G and LTE. They also offer reliable communication with the increased coverage area. The bottleneck to the MIMO-OFDM systems is the estimation of the channel state information (CSI). This can be estimated with the help of any one of the Training Based, Semiblind and Blind Channel estimation algorithms. This paper presents various channel estimation algorithms, optimization techniques and their effective utilization in MIMO-OFDM for modern wireless LTE systems.
Key words: Spectral Efficiency, OFDM, MIMO-OFDM systems, Channel Estimation, Channel State information, Pilot Carriers, subspace approach, LTE.

Delay Efficient Method for Delivering IPTV Services
Delay Efficient Method for Delivering IPTV Services
Abstract: Internet Protocol Television (IPTV) is a system through which Internet television services are delivered using
the architecture and networking methods of the Internet Protocol Suite over a packet-switched network
infrastructure, e.g., the Internet and broadband Internet access networks, instead of being delivered through
traditional radio frequency broadcast, satellite signal, and cable television (CATV) formats. IPTV provides
mainly three services: live TV, catch up TV, and video on demand (VoD).This paper focuses on delivering the
live TV services by exploiting the virtualised cloud architecture of the IPTV and statistical multiplexing. The
VoD tasks are prescheduled so that there will be less Instant Channel Change (ICC) delay. We select a proper
scheduling algorithm for rescheduling the VoD tasks. We then implement the scheduling algorithm for preshifting
the VoD tasks.
Key words: IPTV, Statistical multiplexing, Virtualization, Vo D, Live TV, Scheduling, ICC Delay

Comparative Analysis of HVAC System Based on Life Cycle Cost Analysis
Comparative Analysis of HVAC System Based on Life Cycle Cost Analysis
Abstract: A heating, ventilating, and air conditioning (HVAC) system is designed to satisfy the environmental requirements of comfort or a process, in a specific building or portion of a building and in a particular geographic locale. Efficient design of heating, ventilating and air-conditioning (HVAC) systems is a primary concern in building projects. The objectives of the HVAC system design are to provide a thermal comfort, good indoor quality and energy conservation. For the typical commercial building projects, it is not difficult to acquire the reference settings for efficient operation. However, for some special projects, due to the specific design and control of the HVAC system, conventional settings may not be necessarily energy-efficient in daily operation. The HVAC system design and equipment selection for a commercial building (376 TR) is included as a case study in this paper. The outcomes of this paper are efficient design of HVAC system with minimum energy consumption and equipment selection based on operating and life cycle cost analysis.

Reversible Encrypytion and Information Concealment
Reversible Encrypytion and Information Concealment
Abstract: Recently, a lot of attention is paid to reversible data hiding (RDH) in encrypted pictures, since it maintains the wonderful property that the initial image cover will be losslessly recovered when embedded data is extracted, whereas protects the image content that is need to be kept confidential. Other techniques used antecedently are to embed data by reversibly vacating area from the pictures, that area unit been encryted, may cause some errors on information extraction or image restoration. In this paper, we propose a unique methodology by reserving room before secret writing (i.e reserving room before encryption) with a conventional RDH algorithmic rule, and thus it becomes straightforward for hider to reversibly embed data in the encrypted image. The projected methodology is able to implement real reversibility, that is, information extraction and image recovery area unit free of any error. This methodology embedds larger payloads for constant image quality than the antecedently used techniques, like for PSNR= 40db.
Key words: Reversible data hiding, privacy protection, bar chart shift, image secret writing.
