Most of the time people at rural areas lose their lives due to lack of access to higher end medical treatments and diagnosis. This happens largely because the health care unit at rural areas do not have facilities for higher end treatment. Moreover they are unable to share the patient details to doctors present at other locations for any consultation regarding guidelines to undergo further treatment. This problem can be eradicated by improving the efficiency of healthcare by transferring information from patient at rural health care unit to the doctor at other location through IoT for obtaining guidelines to undergo further treatment based on the patient data. The Internet of Things (IoT) is a device which gathers and share information directly with transmitter and receiver, this enables the doctor to gather record and examine new data streams quicker and more accurately. The IoT technology fetches the data from the sensors attached to patient like heart rate, temperature and patient position.

Many new security threats are found in the outsourcing of data to the cloud. The powerful machines and strong security mechanisms were provided by the Cloud Service Provider(CSP) in early stage.Data auditing scheme enables the cloud users to check the integrity of the stored data without downloading them,they are known as block-less verification.Auditing schemes help the user to interact with the CSP to check the correctness of their outsourced data.The current scheme, achieves a efficient handling of dynamic data.So, we extend the existing threat model by adopting signature exchange idea, so that possible dispute will settle fairly .We enhanced our schema is secure and performance evaluation. Perform evaluation will say about the evaluation of the overhead of data dynamics.We differentiate block indices,tag indices and devise an index switcher to avoid tag recomputation caused by blockup data operation. In existing, the client and the CSP potentially misbehave while auditing and data update. So we extended to provide fair arbitration for solving disputes between clients and the CSP and promotion ofauditing schemes in the cloud environment.
Multilevel inverter is a power electronic device and that is become more or more popularize over the years in high-voltage high-power applications. Multilevel inverters have unique structure which makes it possible to reach high voltages with less harmonic content and lower EMI. The harmonic content of the output voltage waveform decreases as the number of output voltage increases. This paper presents a 21-level multi-level inverter with Asymmetrical cascaded MLI topology. This proposed multilevel inverter topology here is implemented in single-phase with different pulse width modulation (PWM) techniques, which requires less number of components, and gate drive circuit as compared to other multilevel inverters. A multicarrier PWM technique is used for multilevel inverter topology to generate 21-level output phase voltage. Finally simulation results of a 21-level multi-level inverter topology are carried out using MATLAB/Simulink R2014a software version.
This paper deals with the innovation of an add on device which enhances the performance of an automobile. The add on device which is used consists of the use of electronically operated solenoid valve. The valve is placed between the flowline of brake hose and it is manually controlled by the driver. So when the switch is operated any of the flowlines in the brake can be connected and disconnected based on this. This operation is made use in the braking of any of the four wheels while the vehicle is still in acceleration. This method can be used as an alternate for traction control system in a cheaper way. This can also be used in racing events like FSAE or SUPRA and NASCAR racing or in off road cars which is used in Baja. This also reduces the understeer and oversteer problems which is faced by most of the racing cars while cornering. Any failure in design of roll center can be compensated by this. Another main advantage of this system is that, the yawing motion which is occurs in sports car and race cars due to crosswinds and vehicle instability can be controlled by this system by getting input from yaw motion sensor and controlling the straight ahead motion of the vehicle by braking independent wheels.

Automated means of video surveillance for public safety enhancement have existed for quite some time but have gained significant popularity only in recent years. Enhanced awareness for public safety is leading to innovative research by making use of multimedia information and telecommunications for disaster and crime prevention and management of secure environments. However, often the image quality in the video surveillance systems is low and do not fulfill the application requirements. There is a need for smart CCTV surveillance system, where the system is intelligent enough to detect the changes in the live video stream using Image Comparison technique and segregates only the motion detected image. The motion detected images are of low quality due to sunlight exposure and outside noise. To enhance the quality of the image using the Image Filtering techniques to make them more suitable for further processing. In our proposed system, the Comparison is done using covariance Tracking and quality of the image will be improved using Median Filter and Homomorphic Filter, the median filter is a nonlinear digital filtering technique, often used to remove noise. Such noise reduction is a typical pre-processing step to improve the results of later processing. Median filtering is very widely used in digital image processing because, under certain conditions, it preserves edges while removing noise. The Homomorphic Filter is used to improve appearance of an image by simultaneous brightness range compression and contrast enhancement. This system, will provide a complete security and smart image processing system saves only the detected images and reduces the overhead of saving the entire video in hard disk. The image filters improve the image quality by removing noise and correcting brightness and contrast parameters.
The main objective of this paper is healthy monitoring of household appliances and distribution transformers. Discussing the later, the distribution transformers are one of the most expensive equipments in power system. Even a small fault may lead to a very big loss. In order to overcome these faults, monitoring of distribution transformers is very essential. The problems in the former are difficulties in billing and determining the energy usage. The proposed system uses power line carrier communication (PLCC) based system for the continuous monitoring and recording of energy consumption thus helping in energy auditing. The recorded data is sent continuously for every interval of time using the PLCC technique and the data are stored in the database in the EB substation. In addition to this, in the distribution side, various parameters like current, voltage, temperature, power etc., of the distribution transformer are monitored and the data is sent to the database in the sub-station. The collected data are sent to the microcontroller where there is a preset value. The changes in the parameters are sensed and recorded in the microcontroller. Based on the protocol, information is sent to the sub-station and other sequence of operation is performed for the protection of the distribution transformers.
In Computational Social Science, the analytical approaches can be defined by four paradigms namely social network analysis (theory of graph), social simulations (agent-based modeling and cellular automation), text analysis (extracting and classifying the information) and social complexity analysis (analysis complex systems). However for societal and organizational analysis, for analyzing big social data, there exists no approach to model, conceptualize, analyze, predict and explain social media interactions. To overcome this limitation, this paper undergoes another comprehensive approach to big social data analytics called Social Set Analysis. It comprises of theory of social data, philosophies of computational work, formal and conceptual models of social data and generative framework for combining the big social data with the societal and organizational data sets. It also undergoes four case studies covering the range of descriptive, predictive, prescriptive and visual analytical methods for analyzing the big social data sets. Current drawbacks of set-theoretical approach and the future implementations are discussed in this paper.

The manual system of preparing time table in colleges is very time consuming and tedious task which usually ends up with various classes clashing either at identical room or with same teachers having more than one class at a time. Due to manual approach, proper use of resources is neither effective nor efficient. To overcome all these problems we propose to make an automated system with computer assisted timetable generator. The system will take various inputs like number of subjects, teachers, maximal lectures a teacher can conduct, priority of subject and topics to be covered in a week or a lecture, depending upon these inputs it will generate possible time tables for working days of the week, making optimal use of all resources in a way that will best suit the constraints. An appropriate timetable is then chosen from the optimal solutions generated. Timetable creation is a very arduous and time consuming task. To create timetable it takes lots of patience and man hours. Time table is created for various purposes like to organize lectures in school and colleges, to create timing charts for train and bus schedule and many more. To create timetable it requires lots of time and man power .In our paper we have tried to reduce these difficulties of generating timetable by Heuristic Algorithm.
People counting and alert system is proposed to count the number of people, travelling inside the share auto vehicle. The recent survey around Tamil Nadu says that, many accidents was happened because of overcrowded and overloaded of people and luggages in share auto vehicle. “These vehicles are supposed to seat only four or seven people including the driver, depending on the size of auto” quoted on The NEWS Minute. Since the share auto fare is less than or equal to that of a bus fare, people preferring share auto vehicle as it was easily available anywhere at any time. They can also stepped out anywhere based on their choice as it has no stop like that of a bus. In this system, we use an two IR Sensors, One is to count the number of people who are getting into the share auto vehicle and Other is to de count the number of people who are getting down from the share auto vehicle. A LCD (Liquid Crystal Display) is used to monitor the people count inside the share auto vehicle. If the people count exceed 6, then automatically an alert message is sent to the nearby traffic police stated that the auto is overloaded. At the same time Relay Circuit cuts-off the fuel supply to the engine, suddenly the share auto will off. Load Cell is used to calculate the average weight of the load that carried inside the auto, if this load exceed the threshold level, then automatically an alert message is sent to the nearby traffic police through the GSM module. At the same time Relay Circuit cuts-off the fuel supply to the engine, suddenly the share auto will off. Gas Sensor (MQ-2) used to detect whether the driver consumed alcohol or not. If so, an alert message sent to the nearby traffic police. And at the same time Relay Circuit cuts-off the fuel supply to the engine, suddenly the share auto will off.
Double pipe heat exchangers are widely used in various heat transfer applications starting from oil refineries to automobile radiators because of simplicity in design. The rate of heat transfer in a double pipe heat exchanger can be increased by using various heat transfer augmentation techniques out of which dimples is identified as a passive method with least value of pressure drop in comparison with other techniques. In the present work, the performance of double pipe heat exchanger with dimples of various shapes and configurations are investigated using the CFD package ANSYS® FLUENT 16.0 and the arrangement providing efficient heat transfer is identified through CFD results and experimentally validated along with the plain tube model. The inline arrangement with counter flow is chosen for the study with dimple dimension of depth to diameter ratio 0.26. Out of the various pitches ranging from 300mm to 100mm and dimple shapes considered such as hemispherical, square, triangular and elliptical, the hemispherical dimpled tube with a pitch of 150mm arranged in two rows is identified to be the most efficient. The experimental results are in good agreement with the CFD results and hence the studies show that performance of double pipe heat exchangers can be enhanced with the selected dimpled configuration which improves the heat transfer rate by creating turbulence in the flow at a minimum pressure drop.

Based on the studies of semi-automated composite we found that, Web services select concrete services based on the functional and/or non- functional attributes. They do not consider relationships between these attributes in the description of services or the user constraints. Thus, we propose an approach, which relates services to objects (resources) maintained by these services. The user can impose his constraints on the objects affected by the requested services. The affected object and their relationships are described in an intermediate ontology using OWL-DL and SWRL languages. Our selection strategy considers the relationships between services by looking for the dependent instances (conforming objects values) of affected objects that satisfy the user constraints and by combining the related services to get conforming composite services. The proposed selection approach of conforming composite services is implemented and integrated using Ant Colony optimization follow paths with conforming values of concrete services using SPARQL query.

The regions deliver muck of various quality and in various amounts. Ooze coming about because of districts makes issues of transfer. For the most part, dewatered muck are discarded by spreading on the land or via arrive filling. Cremation may be an option arrangement. Be that as it may, a significant measure of fiery debris will be delivered after the consuming procedure and must be discarded by different means. Be that as it may, for profoundly urbanized urban areas, ooze powder transfer via arrive filling won't not be fitting because of land constraint. Cremation may be an option arrangement. In any case, a significant measure of fiery debris will be created after the consuming procedure and must be discarded by different means. This paper exhibits the consequences of the use of slime fiery debris as block making materials. The distinctive designing properties were additionally contemplated by directing tests on block examples of different blend extents arranged. It was seen that when rate of muck was expanded, water necessity and water retention of the blocks expanded. However, in the meantime, compressive quality of the block diminished. Be that as it may, on expansion of bond and flyash the compressive quality expanded and the properties of the blocks moved forward. Advance it can be included that different options like sisal strands, charcoal husk , lime whose expansion should improve the properties which can be considered as the extension for future research.

Energy efficient cluster based data aggregation in wsn with sophisticated collision attacks. According to the cluster-based method, the nodes selected as cluster heads collect data from their cluster members and transfer the data collected to the mobile sink then mobile sink starts the data-gathering route periodically from the starting site, then directly collects data from these cluster heads in a single-hop range, and finally returns to the starting site. However, due to the complexity of the scheduling problem in WSNs with obstacles, the conventional algorithms are difficult to resolve. To remedy this issue, an efficient scheduling mechanism based on spanning graphs. Based on the spanning graph, we present a heuristic tour-planning algorithm for the mobile sink to find the obstacle-avoiding shortest route. We proposed that the security key server as a collision attack in the server. Enhanced Security Scheme able to protect against sophisticated collision attacks, Trustworthiness of sensors. It is effective in the presence of a complete failure of some of the sensor nodes. Robust estimation of errors of individual sensors. An obstacle-avoiding shortest route for the mobile sink is easily. High network lifetime. Simulation results verify the effectiveness of our method.
Individual wellbeing record is a developing patient-driven model of wellbeing data trade, which is frequently outsourced to be put away at an outsider, for example, cloud suppliers. Nonetheless, there have been wide protection worries as individual wellbeing data could be presented to those outsider servers and to unapproved parties. To guarantee the patients' control over access to their own particular PHRs, it is a promising technique to encode the PHRs before outsourcing. However, issues, for example, dangers of security introduction, adaptability in key administration, adaptable get to and effective client denial, have remained the most imperative difficulties toward accomplishing fine-grained, cryptographically upheld information get to control. In this paper, we propose a novel patient-driven system and a suite of instruments for information get to control to PHRs put away in semi-trusted servers. To accomplish fine-grained and versatile information get to control for PHRs, we influence Attribute based encryption (ABE) systems and Proxy re-encryption to encode every patient's PHR document. Not quite the same as past works in secure information outsourcing, we concentrate on the numerous information proprietor situation, and partition the clients in the PHR framework into various security spaces that enormously diminishes the key administration many-sided quality for proprietors and clients. A high level of patient security is ensured all the while by misusing multi-power ABE. Our plan likewise empowers dynamic alteration of get to approaches or document traits, underpins productive on-request client/quality repudiation and break-glass access under crisis situations. Broad systematic and exploratory results are introduced which demonstrate the security, adaptability and proficiency of our proposed plot.
Acoustic echo cancellation is a common occurrence in today’s telecommunication systems. Currently, echo cancellation is a most interesting and challenging task in any communication system. Echo is a delayed and degraded version of original signal that travels back to its source after several reflections. Eliminating this effect without affecting the original quality of the speech is a challenge of research in present days. Most of the real time application concentrates echo cancellation only as a software processing technique. In this proposed system, Source signal (audio) with echo is the input of the designed circuit which is followed by phase shifter and differential amplifier which is interfaced with DSP processor. Then the signal is amplified using amplifier circuit at the output end. Normally noise/echo has to be reduced in negative signal, so here the input is phase shifted from 0◦ to 360◦ which can be tuned and fixed with the required phase. The control operations are performed by PIC16F877A microcontroller. The inputs of differential amplifier are the original source signal and phase shifted signal. At the output end an echo reduced signal is obtained. That signal is further processed using DSP Processor (μPC1892) to improve the quality and given to the amplifier circuit. This system provides more robust and adopts in various real time echo cancellation applications.
The growing number of vehicles on the roads worldwide, lead to increase in the number of road traffic accidents. These are recognized as a major public safety problem. In this context, connected vehicles are considered as the key enabling technology to improve road safety and the emergence of next generation cooperative intelligent transport systems (ITS). In ITS, network services and applications (e.g., safety messages) will require an exchange of vehicle and event location information. Effective lane changing and routing in Vehicular Ad hoc Networks is a challenging task. This paper aims to propose a solution to ensure the safety of drivers while changing lanes on the highways. Efficient and faster routing protocols could play a crucial role in the applications of ITS, safeguarding both the drivers and the passengers and thus maintaining a safe on-road environment. In this paper we propose a Driver Assistance System in Intelligent Transport System based on the speed of vehicles, for effective lane changing in the dynamic mobility model. In our approach we present the lane changing based system on speed and minimum gap between the vehicles. The paper focuses towards the development of an Intelligent Transportation System that provides timely, reliable information to the drivers and the concerned authorities. The test bed is created on the techniques used in the proposed system where the analysis takes place in the On Board Embedded System designed for Vehicle Navigation. The designed system was tested on a Four Lane road at Neemrana in India. Successful simulations have been conducted along with real time network parameters to maximize the QoS (quality of service) and performance using SUMO and NS-2. The system implementation together with our findings is presented in this paper. To illustrate our approach we present some results of the simulation using NS-2.
Here we introduce a system which detects crack on Welded metal piece by using image processing. As image is susceptible to noise we used some image preprocessing steps to detect crack more accurately. System works on most image formats. System mostly focuses on intensity value. This is done for sake of accuracy. System removes all undesirable noise. To detect crack, image is binarized and holes are filled so that image is more clearer to detect cracks. Using this analysis methodology, we detect number of connected objects. Based on the connected components system detects whether image contains crack or not. System is able to detect deeper as well as minor cracks. System uses many image processing steps to detect the cracks. Once the crack is detected by the system, System applies bounding box technology to display the crack to user. Thus , this is an innovative approach to detect crack on Welded metal piece. We used image preprocessing steps as well as crack detection method to get accurate result. The proposed system is able to detect deeper cracks with 80% success rate and minor cracks with 50-60% accuracy.
This work shows the results of Computer numerical control (CNC) Turning Process Parameters for Prediction of improve Surface Roughness and Material Removal Rate (MRR) in the work piece. The performance of Carbide tools was studied to investigate the surface roughness and wear behavior at various machining parameters. Coated and uncoated carbide tools were used in turning stainless steel 303. Machining test were performed in dry cutting condition at various cutting speeds and feed rates. Turning is used to produce rotational, typically axi-symmetric, parts that have many features, such as holes, grooves, threads, tapers, various diameter steps, and even contoured surfaces. Turning is also commonly used as a secondary process to add or refine features on parts that were manufactured using a different process. Hence intelligent hybrid decision making tools are applied to find the optimal process parameters. Obtained results are in good accordance with the published results in the field, validating the effectiveness of regression analysis in modeling of surface roughness in dry turning process
This paper proposes transformer-less Unified Power Flow Controller (UPFC) which can be able to control the parameters of the transmission line. It incorporates back to back inverter that requires large transformers for power flow injection. The transformers are somewhat bulky, very costly and introduce high losses due to magnetic properties of the material used for the erection of core. To conquer this difficulty, a totally transformer-less UPFC is proposed in this work. The proposed controller will reduce the cost and space when compared to the traditional UPFC. A multilevel configuration technique will be used to decrease the total harmonic content. The proposed configuration requires a separate dc source for every level. To reduce the switch count and to eliminate separate dc sources, this multilevel configuration can be further modified. This paper focuses on the performance of transformer-less UPFC involving Fundamental Frequency Modulation (FFM) for reducing the Total Harmonic Distortion (THD) and increasing the efficiency. Voltage sag compensation is implemented during fault condition. Current compensation under non linear load condition. The proposed UPFC is simulated as a result of using MATLAB Simulink.
In the last decades, the number of vehicles has been increasing drastically. Traffic congestion is one of the major problems in the metropolitan cities. The traffic system which we follow nowadays is of fixed time concept. By this method, the lanes with more traffic cannot be given more time for vehicle passage compared to low vehicle lane. Thus, we introduce density based traffic management system. The lane which contains more vehicles gets more signalling time compared to the lane which contains less vehicles. Stealing of vehicles, traffic rule violation, parking the vehicles in the restricted area has also been increasing linearly. Thus, to damp these kinds of activities and also for an effective traffic management, some legal measures has to be taken against the traffic rule violators. For which, keeping track of each vehicle is very important. One of the easier methods is vehicle number plate recognition. Vehicle number plate is a unique combination of numbers and characters. The number plates can be compared with the database so as to come up with specific information such as vehicle owner’s address, place of registration, mobile number etc. The vehicle number plate is segmented from the videos caught on the mass surveillance system using MATLAB. The image is processed further using the same for the clarity of the obtained information. This paper presents a suitable method for localisation, segmentation and recognition of the characters within the located plate. This paper also concentrates on simple but efficient morphological operations such as sobel edge detection method and canny edge detection method. The paper mainly focuses on separation of characters and numbers from the number plate. Each number is viewed clearly. The density based traffic management and violation detector together called as smart traffic management system.
