Various methods are used for analyzing and measuring bioimpedance data for evaluation of clinical status. The objective of this paper is to analyze the variations in electrical impedance measured using four electrode method Impedance is...
In this paper, fractional order Integrator for microwave frequencies is proposed. The fractional order Integrator is designed using microstrip and the operating frequency range of that Integrator is in the microwave range. The frequency response of the proposed fractional order microwave Integrator matches with that of an ideal Integrator. The bandwidth of the proposed circuit is 0.6 MHZ. A comparison...
The aim of our study is the design and development of IOT enabled smart, portable, non-invasive, assistive and precise medical tool based on the methods of Electrical Impedance Tomography which can be deployed for early diagnosis and location of cancerous tissues. EIT is a futuristic medical imaging technique through which one can clinically analyze the image of the body part acquired through surface...
Background: Orthopedic bone drilling is one of the major mechanical process performed by the orthopedic surgeons during the orthopedic surgery. It is a necessary action to fixate the implants during the direct method of fracture treatment. The bone encountered some extra mechanical forces and residual stresses during drilling which can harm the already damaged bone. The Non-favorable combination of...
Electrical Impedance Tomography (EIT) is one of the most potential and promising imaging technique which has wide applications in the medical field. This paper consists of practical phantom study conducted during the designing and development of the Arduino Uno based hardware of a low cost, portable cancer screening device. In this study a phantom tank with 16 Stainless Steel electrodes is developed...
In the present industrial world, induction motors are mainly used as prime movers. Its failure not only effect process downtime but also leads to production loss. Therefore, its condition monitoring is essential as it increases its efficiency and availability. However, there are certain failures that are still left undetected by commonly used vibration and current based condition monitoring techniques...
Induction motors are widely used prime-movers in most of the industrial applications due to its high efficiency, rugged design and easy control. Reliability and availability of induction motors is one of the required parameters in order to reduce down-time of the entire rotating machinery system. Vibration analysis and motor current signature analysis (MCSA) are widely used diagnostic techniques for...
In the present industrial scenario, machinery reliability and maintainability plays very important role in meeting the tight production schedules. In such systems, unexpected failures need to be minimized by effective fault diagnosis methods. Induction motors are used as prime movers in most industrial machinery. Therefore, effective fault diagnoses of induction motors are vital in achieving the minimal...

This paper consists of designing and development of hardware for EIT system using microcontroller MSP430G2 and AVR ATMEGA 16. A 16-electrode phantom...
This paper presents design, analysis and simulation of fuzzy logic controller for indirect field oriented control (FOC) of induction motor drives. The induction motor drive is controlled using a FOC, which allows a fast transient response of the system by controlling a decoupled flux and torque components. Moreover, a fuzzy pre-compensated proportionalintegral (PI) controller is used for attaining...
A new methodology is developed for drying the grains by using difference in air humidity at inlet and outlet section of the drying chamber. Programmable Logic Controller (PLC) is used to control the entire drying procedure automatically. The use of grain dryers will reduce the environmental dependence for the drying process and its automation will make drying more efficient and uniform, thus saving...
In this paper, the effect of Mobility of Mobile Wi-max Subscribers on VOD over Wi-max is analysed by considering the SVC codes for video streaming. This experiment has been carried out using OPNET Modeller 14.5. In this experiment the placement of nodes are circular within hexagonal cell of radius 2 km. To compare the performance of IPTV over Wi-max, the Packet Delay Variation, Packet End to End Delay,...
This paper presents the control of elevator system using Siemens LOGO PLC. The system is programmed to drive a dc motor for forward and backward motoring mode with sensors at each floor, emergency STOP switch for maintenance purpose or to prevent any accident inside the lift & door switch for safety purpose. The system is also programmed to conserve energy by automatically switch off lights and...
The grounding grid provides a common ground for the electrical equipment as well all the metallic structures in the substation. Effective Grounding system design is important as it deals with personnel safety and protection of electrical equipment. Earth Fault gives rise to potential gradient within and around the substation. This voltage gradient should not exceed the tolerable human body limit....
In a deregulated power market, there is tendency of big generator and consumers to manipulate the market by creating congestion in the system. Congestion relief management (CRM) by congestion relief charge (CRC) is like a ancillary service which, maintains the system in electricity market. Generating company creates gaming for earning more profit by transferring power over ATC limit, which is called...
In this paper, we present algorithms for Grid resource provisioning that employ agreement-based resource management. These algorithms allow userlevel resource allocation and scheduling of applications that are structured as a precedenceconstrained set of tasks. We present a provisioning model where the resource availability in the Grid can be enumerated as a set of slots. A slot is defined as a number...
A statistical interpretation of existing parallel magnetic resonance imaging methods reveals that th eunderlying noise model is of additive independent Gaussian noise. In reality MR imaging processes suffer from a variety of noise, errors and other uncertainties. A careful statistical analysis of these uncertainties can potentially allow significant improvement of the reconstruction process. In this...
High resolution 3D coronary artery MR angiography is time-consuming and can benefit from accelerated data acquisition provided by parallel imaging techniques without sacrificing spatial resolution. Currently, popular maximum likelihood based parallel imaging reconstruction techniques such as the SENSE algorithm offer this advantage at the cost of reduced signal-to-noise ratio (SNR). Maximum a posteriori...
