ANALYSIS AND DESIGN OF NUCLEAR RADIATION ATTENUATING ENTRANCE CORRIDOR

Abstract

In the past few years, the increase in the number of terrorist attacks has shown that the effect of blast loads on buildings is a serious matter that should be taken into design consideration. These man-made disasters have created a challenge to structural engineers world over about the deficiency in the design process. Blast loads are extreme, instaneous, unpredictive impulses acting over milliseconds. Due to this nature of blast loads, it is complicated to analyse the dynamic responses of the structures. Usage of advanced engineering materials for construction can solve these structural problems to an extent. This paper presents the analysis and design of an underground blast resistant shelter made up of high performance fiber reinforced cementitious composites (HPFRCC). This research focuses on a nuclear radiation attenuating entrance corridor, module of the shelter. The dynamic behavior of module under blast load is studied in finite element software Abaqus CAE 6.12. It is observed that the material stress-strain behavior is greatly influenced by strain rates of loadings. Shelter manually designed using codes in limit state method is verified with the analytical analysis.

Vertical Farming: a novel farming technology

Abstract

Vertical farming is a concept that argues that it is economically and environmentally viable to cultivate plant or animal life within skyscrapers, or on vertically inclined surfaces. It is the concept of growing food crops in multi-storey green houses, in a controlled environment with the aid of modern technologies. A Vertical farm is always incorporated with renewable energy systems, soilless culture and artificial lighting. The use of soilless culture technologies namely Hydroponics and Aeroponics saves huge amount of water. The LED Grow lights and computerized sensing systems control the micro climate. This guarantees the year round crop production inside a vertical farm. It is possible to cultivate crops anywhere on the globe irrespective of the climate conditions. Moreover the productivity of land can be increased tenfold, since the crops are grown in each floor. Designers all over the world are inspired by the concept and numerous projects are on their infancy. Glass is replaced by cheaper translucent ETFE membranes in latest vertical farm designs. It’s high time to check the need of vertical farming among the leading global scenarios such as population inflation and global warming. The idea still remains to be proved.

A New Technique For Iris Recognition

Abstract

Abstract: Reliable authorization and authentication are becoming necessary for many everyday applications such as boarding an aircraft, performing financial transaction, logging to a secure system etc. Identity verification becomes a challenging task when it has to be automated with high accuracy and with low probability of break-ins and low rates of false match. Moreover, person verification is not a new problem and society had created three traditional modes of designation: 1. Possessions: Physical possessions such as keys, passports and smart cards. 2. Knowledge: Pieces of information those are secret and known only to the right person such as PIN, passwords, user names etc. 3. Biometrics: Physiological and behavioral characteristics of individuals that distinguish one person from the others. These characteristics are different in each person. Iris is the best characteristic that can be used for person’s identification and authentication in comparison with fingerprints, face, voice, and signature. It combines all the characteristics that a practical biometric should have. Iris pattern is unique to each person even that difference exists between twines. In the same time, the iris pattern is different between the right and left eye of the same person. Moreover, iris is very stable and changeless human characteristic over the time. Also, the sensing device that is used in order to measure the iris characteristic is a camera. This will be convenient for user population. Iris pattern is the safest biometric of all because it cannot be duplicated. Iris Recognition System project's goal is to create two Biometric subsystems; one for enrollment and one for authentication.

Feature level fusion technique used to fuse the results of face & palm prints and then gives the output as per neural network classifier which gives the correct information about genuine or imposter identity. security becomes a most important issue regarding a spoof attack. So, multimodal biometrics technology has attracted substantial interest for its highest user acceptance, high security, high accuracy, low spoof attack and high recognition performance in biometric recognition system. The proposed work is an implementation of person identification fusing face, palm biometric modalities used PCA based neural network classifier for feature extraction from the face and palm images and hamming distance for calculating iris templates. These features fused and used for identification. Better result was obtained if the modalities were combined. Identification was made using Eigen faces, Eigen ears, Template of iris and their features tested over the self created image database.

Single Phase And Three Phase Supply for Same Variable Frequency Drive

Abstract

Manufacturers are commonly producing three phase variable frequency drives but due to unavailability of three phase ac power, three phase variable frequency drive are often required to operate from a single phase supply, in rural areas.Powering up three phase variable frequency drive from a single phase ac source results in many issues such as higher rms value of input diode current, higher ripple voltage across dc bus capacitor, higher peak input current, higher input current distortion, lower power factor, and poorer system efficiency. There are many techniques, both passive and active that are employed to address the issues faced when a single phase ac supply is used to power three phase variable frequency drives. Here proposes a new active solution for problems that occur when three phase variable frequency drive is powered from a single phase ac source and by using this technique no modification of the existing three phase variable frequency drive is required and hence same variable frequency drive can be used for both single phase supply and three phase supply based on its availability with an additional bidirectional switch.

MRS BASED SPEED ESTIMATOR FOR VECTOR CONTROLLED INDUCTION MOTOR DRIVES

Abstract

Reference Adaptive System (MRAS) based speed sensorless estimation of vector controlled induction motor drives are presented in this paper. New speed and current estimation techniques are presented. These are used to formulate a single current sensor based vector controlled drive. The proposed method is immune to stator resistance variation. MRAS is a speed estimation method having two models. The error between the two models estimates the required speed. With the help of a vector rotator the two phase currents are transformed to actual values of d and q axis currents. The current estimation on the other side extracts the information of the phase currents in two phase stationary reference frame by using the corresponding synchronous reference frame variables and the vector rotator. The new speed and current estimation techniques are simulated in MATLAB/SIMULINK.

Image Resolution Enhancement Using NSCT with LBP as Feature Model

Abstract

In this paper, we propose a new technique for feature preserving spatial resolution enhancement of an image captured at low spatial resolution. We use a training database containing low resolution (LR) images and their high resolution (HR) versions. In an image, different features like edges, corners, curves and junctions are important to convey its local geometry. We use Local Binary Pattern (LBP) operator to represent texture of an image. The missing high resolution details of the low resolution observation are learnt in form of Non-subsampled Contourlet Transform (NSCT) coefficients of the high resolution images in the training database. We demonstrate the effectiveness of the proposed technique by conducting experiments on real world gray scale images. The results are compared with existing learning-based approaches. The proposed technique can be used in applications such as medical imaging, remote surveillance, wildlife sensor networks where the transmission bandwidth, the camera cost and the memory are main constraints.

Abstract

Cloud computing environment provides large scale resources and services for the users through the Internet environment. Shared services are provided to execute user required services with cloud resources. Big data applications are building to manage huge amount of data values. MapReduce techniques are applied to divide and process the data and tasks. Hadoop is a widely-adopted distributed computing platform using the MapReduce parallel processing paradigm. Service details and user access information are maintained under the cloud for service discovery process.  Service access information are maintained for the future references to assess the performance levels. Service recommendation tools are employed to discover appropriate services for the users. Big data applications are constructed to manage customer, services and access information for the service recommendation process. Scalability and inefficiency are the main problems identified under the traditional service discovery process. The service recommender systems use the same rating and ranking model for the discovery process.  A Keyword-Aware Service Recommendation (KASR) method is adapted for the service discovery process. The KASR method is mainly focused to perform personalized service recommendation process with user preferences. Keywords are used to indicate users' preferences. The user-based Collaborative Filtering algorithm is adopted to generate appropriate recommendations. Semantic query based service discovery process is supported by the KASR scheme.  KASR is implemented on Hadoop to improve the scalability and efficiency on big data. KASR significantly improves the accuracy and scalability of service recommender systems. 

Experimental Investigation on Corrugated Interlocking Paving Blocks (CIPB) for strength and durability study.

Abstract

In era of rapid infrastructural development, concrete is second largest used material after water which requires large quantity of Ordinary Portland cement (OPC) [1]. But at the same time OPC production contributes to CO2 generation and also consumes lot of energy during production. Hence there has always been a requirement of alternative material for cement. It would have been more beneficial if such a material is derived from industrial waste, without consuming extra energy for raw material manufacturing and processing. Geopolymer has been a solution for all these requirements. It is obtained from flyash and alkaline solutions which provide properties similar to normal OPC. In fact by selecting different molarity and binder ratio combination its properties are examined to see whether they show incremental values or not. Use of Geopolymer in paving block has been experimentally assessed in present work. Different strength and durability parameters of paving block are examined. The results show the enhancement of strength and increase in durability for Geopolymer based paving block. Thus it can be alternative solution for use at places imposed of heavy duty impact loads and continuous abrasion.

SPEED CONTROL OF FOUR QUADRANT PMDC MOTOR DRIVE USING PI BASED ANN CONTROLLER

Abstract

In recent years the availability of petroleum resources have decreased, which has paved the way for Hybrid Electric Vehicles (HEVs). The propulsion technology used in these vehicles are more eco-friendly and reduces the consumption of petroleum resources to a large extent compared to conventional automobiles. Both ac and dc motor drives are used in this field. Due to its high reliability, flexibility, simplicity and economical cost dc drives are widely used in the field of HEV’s. In order to achieve better drive range and improved performance of the motor, control techniques are necessary for dc to dc power converters in electric cars. The main problems faced during the driving operation are fluctuations in input battery voltage, load variations which decreases the performance of the drive. So it is necessary to maintain a constant output voltage of dc to dc converters irrespective of these variations for better performance. Therefore proper controlling techniques should be provided. This paper mainly focuses on the speed control of four quadrant PMDC motor using PI based Artificial Neural Network (ANN) controller.

DESIGN AND IMPLEMENTATION OF FPGA BASED MULTIPURPOSE REAL-TIME CONTROLLER FOR HYBRID STEPPER MOTOR

Abstract

Stepper motors are one of the most widely used special electrical machine where controlled movement is mandatory. Hybrid stepper motors (HSM) exhibit high static and dynamic torque and run at very small step angles. They are also used in extensive industrial applications. Due to the development of digital control systems, HSM became more attractive to be used in robotics applications, nuclear reactors and computer numerical control machines where they have to perform high-precision positioning operations without any feedback sensor. The conventional HSM control using microprocessors and microcontrollers have limitations like sequential program processing, increased delay etc. which makes real time control a burden. The objective of this paper is to design and implement a cost effective multipurpose real-time controller using a single Field Programmable Gate Array (FPGA) platform for HSM. The Parallel processing power of FPGA is utilized here to implement multiple stepper motor controls. Hence, this work focuses on the hardware design and implementation of a high performance FPGA based algorithm developed using Very High Speed Integrated Circuit Hardware Description Language (VHDL) coded in Xilinx ISE, simulated and verified in ModelSim software which controls the HSM through driver circuit with dual H-bridges which provides simultaneous real-time control over speed, position, no of steps, switching modes and direction of the stepper motor within the motor constraints according to the input control logic given by the user.

A Fast CAP for Haze Removal and Image Inpainting Based on Coherence Transport

Abstract

Single image haze removal and image inpainting has been a challenging task due to its ill-posed nature. The proposed system introduce a simple and powerful Color Attenuation Prior (CAP) for the haze removal from a hazy image and an image inpainting method based on coherence transport for region filling and object removal. Depth information can be recovered by creating a linear model for modeling the scene depth of the hazy image under this CAP. The haze can be removed easily from a single hazy image with the recovered depth information. Then an image inpainting method based on coherence transport is used to better maintain structure coherence and texture clarity of the inpainted region of the image. This work can resolve the difficulties by other haze removal and inpainting techniques and better suit the problems.

Scheduling and Sharing of Services with Efficient Key Management Scheme

Abstract

Many emerging applications in mobile networks involve group oriented communication. Multicast is an efficient way of supporting group oriented applications. So secure multicast application require efficient key management scheme that provide access control. The proposed system uses a Slot based Multiple Group Key Management (SMGKM) scheme which minimize the rekeying transmission overhead. Even though it reduces transmission overhead it does not schedule the services properly. When multiple members of same cluster are requesting for the same services, there should be a scheduling mechanism to improve the efficient use of resources. The proposed system also provides sharing of services that allow mobile node to act as a service provider for the new receivers which will help to reduce the service delay and also it improve the efficiency of the system.

Investigation of Effect of Joint Clearance on Vibration of Planar Mechanism

Abstract

A mechanism is a device designed to transform input forces and movement into a desired set of output forces and movement. Clearances in mechanism are unavoidable due to assemblage, manufacturing errors and wear. Moreover, the clearance occurs in each joint with the movement of mechanism. The movement of the real mechanisms is deflected from the ideal mechanism and motion accuracy is decreased due to the joint clearances. The existence of clearance in joints also causes impact dynamic load, affects the transfer of system load, and may lead to destruction of the mechanism and failure of the mechanism’s kinematic and dynamic outputs. These clearances modify the dynamic response of the system. This work has investigated the effect of joint clearance on the vibration of mechanism. The vibration produced in the joint are depends on the clearance provided in joints and the speed. The aim of this study is to determine the effect of different clearances and speed on vibration. For this purpose, a four bar mechanism with spherical revolute joint with different clearance is fabricated in a combination of two levels of clearance and three levels of speed. Taguchi’s design of experiments is used which resulted in eighteen number of samples and experimental runs. The vibrations in the joint are recorded using accelerometer. . By applying design of experimentation technique and using Taguchi methodology results have been analysed and optimum levels of each controlling parameters are determined. The results those are analysed compared with the results obtained for the ideal clearance. The outcomes of this study will be helpful to decide different parameters and their levels to be used when mechanisms is operated with dry contact for various applications.

Indirect torque control of SR motor based on Hysteresis current controller with PI control for speed regulation

Abstract

As traditional control schemes, open-loop Hysteresis and closed-loop pulse-width-modulation (PWM) have been used for the switched reluctance motor (SRM) current controller. The Peak to peak controller induces large unpleasant audible noises because it needs to vary the switching frequency to maintain constant Hysteresis current band. In contract, the Hysteresis PWM controller is very quiet but difficult to design proper gains and control bandwidth due to the nonlinear nature of the SRM. In this thesis, the ac small signal modeling technique is proposed for linearization of the SRM model such that a conventional PI controller can be designed accordingly for the PWM current controller. With the linearized SRM model, the duty-cycle to output transfer function can be derived, and the controller can be designed with sufficient stability margins. The proposed PWM controller has been simulated to compare the performance against the conventional controller based system. The closed loop PI controller is used to run the SR motor speed as constant.

Fall detection is a foremost task in the public healthcare area, particularly for the elderly and consistent system is a need to alleviate the sound effects of falls. An effective fall detection system is essential to bring critical support and to considerably reduce the medical care costs related with falls. The persons above 70 years of age were dead produced by fall incident. Hence we need consistent user based fall detection system. This fall detection system is proposed for elderly person monitoring which is based on smart sensors worn on the body and working through home networks. The key part of this system is ARM 7 Microcontroller. To detect the unintentional falls, a small low power tri-axial accelerometer is used and to detect heart rate cardio tachometer sensor is used. This specified 3-axis accelerometer sensor is used to measured acceleration of the body in all the three axes. By using information composed from an accelerometer and cardio tachometer the effects of falls can be noted. The system will also send the location of the person using GPS. Location information, which gives the information of longitude and latitude. The fall detection can be described as the rapid change from the front, right, left, back fall position information. The family members know how to, with permission, access this information and consider the safety of the elderly person. The system will contact the emergency center instantly through text message using GSM modem.

Efficiency Improvement in Bufferless NoC

Abstract

Equally further complex SoCs begin to appear, the job of communicating in between the subsystems of a SoC can’t be tolerably controlled by bus based communication architectures. Network on Chip’s (NoCs) are projected to be possible alternative to bus based architectures for communication inside SoCs. Succeeding the hasty technological growth, the complexity turns out to be one of the best compelling features in the plan of embedded systems. Timing and cost issues chaperon to increase to the difficulties in understanding of network-on-chip , NoC applications, where many Intellectual Property (IPs) such as memories, processor cores, peripheral devices and DSP processors are sited together ,on a solo die. These modules communicate, a lot, by way of a shared resource, the NOC’s. Congestion is central concern in networks and ominously distresses network performance. The Scheduler turns as the central switch arbiter. The important components in systems which have shared resources are arbiters and a centralized arbiter is a strongly assimilated design for its input needs. In this paper, we study a new centralized arbiter, which may be used in arbitration of a crossbar switch in NoC routers concluding different papers. We discuss Islip arbiter for NoC

Abstract

Throughout the period between harvesting and consumption, temperature control has been found to be the most important factor in maintaining product quality. Fruits, vegetables and cut flowers are living, respiring tissues separated from their parent plant. Keeping products at their lowest safe temperature (0 C or 32 F for temperate crops or 10-12 C or 50-54 F for chilling sensitive crops) will increase storage life by lowering respiration rate, decreasing sensitivity to ethylene gas and reducing water loss. Reducing the rate of water loss slows the rate of shriveling and wilting, causes of serious postharvest losses. Keeping products too cool can also be a serious problem. Cooling involves heat transfer from produce to a cooling medium such as a source of refrigeration. Heat transfer processes include conduction, convection, radiation and evaporation. Horticultural products are stored at lower temperature because of their highly perishable nature. There are many methods to cool the environment. Hence, preserving these types of foods in their fresh form demands that the chemical, bio-chemical and physiological changes are restricted to a minimum by close control of space temperature and humidity. The high cost involved in developing cold storage or controlled atmosphere storage is a pressing problem in several developing countries. Evaporative cooling is a well-known system to be an efficient and economical means for reducing the temperature and increasing the relative humidity in an enclosure and this effect has been extensively tried for increasing the shelf life of horticultural products in some tropical and subtropical countries. Thus, the evaporative cooler has prospect for use for short term preservation of vegetables and fruits soon after harvest. Zero energy cooling system could be used effectively for short-duration storage of fruits and vegetables even in hilly region. It not only reduces the storage temperature but also increases the relative humidity of the storage which is essential for maintaining the freshness of the products. So, this report is about the design and development of Evaporative cooler with its experimental analysis by using peltier module and heat exchanger. The prime objective of this project is to be design and develop the evaporative cooler with its main components and then calculate the results experimentally. After the development, COP are calculated first by using Peltier Module and then by combine with Heat Exchanger which were found effective. By using Evaporative cooling system with only peltier module, we get COP between 0.31 to 0.59 and by combine with Heat exchanger; we get in between 0.62 to 0.72 which is greater than conventional evaporative cooling. The results obtained from both were compared and found that Evaporative cooling system combining with Peltier Module and Heat Exchanger is more effective.

solid Electrolytes

Abstract

Solid State Ionics continues to be a rapidly developing research field because they exhibit high ionic conductivity; negligible electronic conductivity and low value of activation energy for ion migration at temperatures below their melting point are known as Solid Electrolytes (SEs) or Super Ionic Conductors (SICs) or Fast Ion Conductors (FICs). These solid electrolytes created a great deal of attention in modern researchers because of their unique transport properties and potential applications. This paper mainly explains about various types of solid electrolytes (conductivity values) and their various applications in solid state electrochemical devices such as rechargeable batteries, electro-chromic displays, solid state sensors, super capacitors thermoelectric devices, fuel cells, solar cells, memory devices and high energy storage batteries discussed.

Analysis of Engine Oil Kinematic Viscosity by Adding Viscosity Index Improver

Abstract

Viscosity is a property of a liquid and is defined as the resistance of a liquid to flow. The purpose of this experiment is to determine the kinematic viscosity with varying percentage weight of viscosity index improver. A redwood viscometer is used to measure the kinematic viscosity of engine oil samples. Four stroke engine oil SAE10W30, SAE15W40 and SAE20W50 are taken and two types of viscosity index improver (OCP) are added in the three grades of oil by varying the percentage weight by 5%, 10%, and 15% of additive. The presence of viscosity index improver has significantly improved the kinematic viscosity of engine oil.

Probabilistic Model for Statistics of Total Damage on Different Insurance Items

Abstract

This paper deals with the tariff calculation model for estate insurance using the three years' loss portfolio of BUTA insurance company. Based on company policies’ data model of total damage is constructed. Mathematical formulation of this problem requires the use of several parameter estimating methods and hypothesis tests. The results have statistically been analyzed for making exact decision of tariff's rate. Finally, estimating tariffs are compared with the corresponding actual data.
