MEMS based flow rate sensor and flow direction sensor is a crucial to the determination of exact fluid flow path. Conventional rectangular cantilever beam detects based on the surface strain of the beam with respect to the mass flow. Different structured beam will greatly affect the sensitivity. In this paper different geometries of cantilever beam such as rectangular, inverted trapezoidal, triangular are designed and simulated using the finite element software INTELLISUITE 8.7. The simulation results show that the inverted trapezoidal geometries having the more deflection at same stress of the conventional beam and thus increase the sensitivity by approx. 1.45 times.

Battery powered electric vehicle provides almost zero vehicle emission and very low noise. Many countries provide road side stations or parking location with electricity plug for charging electric vehicles (EVs). The main concern when it comes to electric vehicle is charging of the battery pack present in it. This gives an incredible increase in the travel time and new investment. Hence, this paper proposes a novel automatic energy harvesting (AEH) system for electric vehicles charging. This system has a wind duct and a drive train assembly integrated with a control system to avoid the need of driver involvement. This system is capable of estimating various parameters of wind duct and battery packs present in the vehicle. The axial and rotational velocity components of turbulent flow wind duct, available power, and state of charge (SOC) of battery has been calculated. The simulation result show that the thickness of both the axial and rotational boundary layers depends on the RN, velocity ratio, and angle of wind duct. SOC error estimation shows that the performance EKF is better and suitable for battery management system. This automatic recharging system aims at reducing the travelling time and increases the usage of EVs.

Nano thermoelectric generator have a basic concept of converting the heat energy into water steam which runs the turbine which produces the electrical energy most of the steam or air turbine that are operating now are having the input heat from coal or nuclear power. Which is a drastic waste of input power by the help of solar heat which can be used to heat the fluid material which is used to run the turbine some of the basic problems that we face is the heat transfer is not so good, resulting in poor efficiency this problem is overcome with the help of nanorods like carbon nan rods which have a high heat conducting capacity which helps in efficient heat exchange which is not given in general steam or air turbine plants. On the other hand the heat lost during the condensation process can be used with the help of thermoelectric effect which improves the efficiency and gives more power.

Webometrics is a measurement of the world's academic and scientific research progress. In this system various universities researches and their development are noticed using the updates of the websites. Administrators and managers of these websites are making efforts to improve the ranking of these organizations according to their rating. On the other hand that is observed, there are not only academic universities are played role in research, various different companies and organizations are also participating in research and development. Therefore a new kind of ranking system is required to provide ranking for all the different kinds of organizations who are participating in Webomatrix. In this paper a novel webometrics development and ranking scheme are proposed and implemented, which helps to evaluate the rank of different research organizations according to their improvements and the quality of work using research documents available over web domains. The presented ranking methodology provides a clustered domain ranking system by which domain specific ranking becomes more precise and accurate.

The wavelet transform is a well-known tool that can be used for many signal processing applications. This paper investigates the success of Double Density Discrete Wavelet Transform (DDDWT) to denoise the signals and images. The performance analysis of one dimensional signal and two dimensional images are compared with discrete wavelet transform (DWT). The Double Density DWT has an one scaling function and two wavelet functions. With these two wavelets gives a closer spacing between adjacent wavelets within the same scale. It is found that with same level of processing, the double density DWT (DDDWT) performs better than DWT.

Power consumption is the key challenge of designing a reliable wireless sensor embedded computational system. For a deployed WSN, the infrastructure of various motes is built using the traditional 8-bit 5V DC operative microcontrollers because of its low-cost. There exist many schemes and power reduction techniques for a single node. However, the power consumption for a Coordinator node wherein the user or other network is typically interfaced is often been ignored since the same 8-bit microcontroller is used as the infrastructure to design. This paper suggests the usage of ARM LPC2138 as the MCU to be replaced in Coordinator irrespective of other node's architecture of WSN. The efficient, clean and bug-free device driver implementation to connect a LCD for displaying messages is presented in the first part of the paper. The user input through a low-cost dumb conventional 4×3 matrix keypad is implemented and suggested in the second part of the paper. The integration of these two drivers with the UART driver for achieving WSN related prototype is discussed in the next phase of the paper. This firmware is implemented using Keil4 IDE and the hardware design is validated using Proteus7.8i. The firmware debugging techniques strategy being opted for the implemented drivers is illustrated along with the Results and a note with the current work at the end of the paper.

The main objective of this project is to design a MEMS Vibratory gyroscope. A gyroscope is a device used for measuring or maintaining orientation, based on the principle of angular momentum. MEMS gyroscopes are gaining popularity because of their high accuracy and low manufacturing costs in large quantities. Gyroscopes can also be used for detecting and monitoring Gait phase detection system (GPDS). In case of Gait phase movement asymmetry is one of the motor symptoms. Improper Gait phase is the disorder of the central nervous system due to Structural defect walking pattern. Gait phase of a person is important to know which plays a number of important physiological roles. Once Improper Gait phase detected at an early stage by the use of MEMS vibrating gyroscopes, patients are alerted with signals in order to prevent the fall.

Use of polymer material in manufacturing of microstructures has been a trend in recent MEMS technology. One such trend is employed in this paper where in four different micro structures are designed and simulated using SU8 polymer material. All the architectures are simulated using COMSOL Multi physics to compute modal frequency. The simulation results are verified analytically using a standard mathematical equations. The simulated architectures are then modelled using neural network to compute the dimensions of a given architecture for a desired modal frequency. Also the simulation results, the analytical results and the ANN results are compared for the various architectures.

Most of the researchers have developed the solution for designing multiplier and accumulator (MAC) section used in Digital signal processor by using number of algorithms and architectures. Multiple constant multiplications (MCM) is a factor which dominates the complexity of many digital signal processing systems. This paper deals with the designing of digit serial FIR filter which will reduce the complexity of multiple constant multiplications in digital signal processors by reducing the gate area and power consumption. In order to achieve this, shift/ add architecture concept is proposed.
