A new fault location algorithm based upon two end synchronized data for high voltage transmission line is proposed which considers arcing fault calculation. In this work least error square (LES) principal is used without considering the line parameters. The least error square principle is used on positive sequence equivalent circuit to calculate the fault distance from the reference bus. This algorithm is simple to understand and easy to implement. since it is independent of line parameter therefore it can be applied to both lumped and distributed transmission lines. This algorithm provide promising results against the variability in fault resistance on the account of two end data. PSCAD transient program is been used to create fault cases along with MATLAB, which calculate fault location. The results shows the effectiveness of the proposed algorithm.

A compact coplanar waveguide (CPW)-fed F-shaped stub printed antenna is presented. The first and second resonance modes are excited due to F-shaped stub connected to modified CPW ground plane and third resonance mode due to modified L-shaped CPW feeding. The impedance bandwidths of 190 MHz (2.06–2.25 GHz) for UMTS band, 530 MHz (4.61–5.14 GHz) for 4.9 GHz public safety WLAN, 1490 MHz (5.45–6.94 GHz) for 5.5 GHz WiMAX, 5.8 GHz WLAN, and ITS (intelligent transport systems) bands application is achieved. The proposed antenna provides circular polarization (CP) in the 4.9 GHz public safety WLAN band with 3-dB axial ratio (AR) bandwidth of 170 MHz (4.88–5.05 GHz) and linear polarization in the other two bands. By employing a single switch between F-shaped arms and changing the state of switch, antenna exhibits narrowband and wideband functionality with dual- and triple-band behaviour while keeping antenna size 25 × 25 mm2.

The conventional method of testing water quality is to gather samples of water manually and send to the lab to test and analyze. This method is time consuming, wastage of man power, and not economical. The water quality measuring system that we have implemented checks the quality of water in real time through various sensors (one for each parameter: pH, conductivity, temperature) to measure the quality of water. The ZigBee module in the system transfers data collected by the sensors to the microcontroller wirelessly, and a GSM module transfers wirelessly the data further from the microcontroller to the smart phone/PC. The system also has proximity sensors to alert the officials by sending a message to them via the GSM module in case someone tries to pollute the water body. This system can keep a strict check on the pollution of the water resources and be able to provide an environment for safe drinking water.

In this paper, control and operation of a microgrid having inverter based solar photovoltaic (PV) and diesel engine is presented. The microgrid is designed to meet rural applications. In the proposed microgrid, a water pumping system is considered as a dump load for ensuring economic operation of microgrid. Three scenarios i.e fully loaded, partially loaded and lightly loaded are considered to evaluate the performance of proposed microgrid. In fully loaded condition, PV operates at MPPT for extraction of maximum power and the diesel generator is operating at rated power. In second scenario, when the power demand is less, PV operates in de-rating mode to avoid operation of diesel generator below minimum operating limits; and thus ensures economical operation of the microgrid. However in lightly loaded condition or in case of low solar irradiation when PV power is already close to zero; a dump load is turned ON to ensure the operation of diesel generator in proper technical range. The paper shows the control of water pump as per the available demand and generation. To verify the performance of the proposed system, simulation in MATLAB/SIMULINK environment is performed and it is concluded that proposed microgrid with water pumping system as dump load ensures economical operation of microgrid.

this project entitled “Driver Soberness System for road vehicles” is a safety system. The basic idea behind this system is to prevent and person under influence of alcohol to start and drive any road vehicle. The system takes power form the vehicles existing battery and is switched on as the key of the vehicle is set to ON position. The system then waits for a sample of breath as an input and then analyzes it for traces of alcohol using -OH and pressure sensors. If any trace of alcohol is found, the ignition relay is then kept OFF and the vehicle will not start even if the key is turned to ignition state. This allows the system to behave as an ignition lock device. Driver soberness system also measures the speed of the vehicle using a hall-effect sensor in running state along with the tilt in the steering wheel with the help of GY-61 acceleration sensor. If the set limit is exceeded the system then alerts the driver with a warning signal via a glowing LED and a buzzer indicating a case of rash driving.

As the network technologies are improving, more challenges are coming forward in form of huge amount of data being transferred through the network. A large portion of such data is of multimedia type consisting of huge amount of digital images being sent and received through the network. In this paper, an integrated image compression and encryption technique using run length encoding scheme and henon chaotic map is presented. Run length encoding scheme is common scheme and a natural choice for image compression. Run length encoding generates (value, count) pairs such that the value is repeated ‘count’ number of times. In this paper, we used the run length encoding technique for lossy image compression. We designed a lossy run length encoder that exploits the pixel redundancy and visual imperceptibility of human eye to fine details in the digital images. Along with compression we perform image encryption using henon chaotic map. After encryption the size and resolution of the image is changed that further enhances the security. Various experiments are performed calculating various performance matrices-histogram, information entropy, PSNR, Compression ratio, and MSE. The algorithm is secure enough to thwart various statistical attacks while being easy to implement and fast.

In this paper, a two-dimensional photonic crystal based tunable optical filter having Si rods with different shape cavities, as H-shape, square and circular is designed and investigated. The shape of Si rods is also changed from circular to square and the shift in resonating frequency of filter is achieved. The area of each cavity has been kept constant for achieving the result. The filter is designed by creating defects based resonator and two line defect based reflectors. These defects are formed by simple removing the Si (dielectric material) rods. The designs proposed in this paper are suitable in optical circuits as wavelength shifting circuits. Also, they can be used as noise filtering devices for communication purpose.

Novel elliptical spiral photonic crystal fiber(PCF) having ultra-flattened negative dispersion, high nonlinearity and high birefringence is proposed. The finite element method is used to optimize the guiding properties. This design provides negative dispersion that is ultra-flattened within range of wavelength from 1385 nm to 1990 nm with deviation of ± 1.5 ps/nm/km. Dispersion value of −93.577 ps/nm/km at 1550 nm wavelength is achieved. The numerical results also indicate the birefringence up to order of 10−2 and nonlinear coefficient of (678.264, 763.485) W−1km−1 at 1550 nm wavelength for fundamental X and Y polarized modes.

This paper presents a new CMOS realization of voltage differencing buffered amplifier (VDBA). The input stage of VDBA is resistively compensated and output stage is a super source follower (SSF). The resistive compensation enhances gain bandwidth product (GBW) and buffer stage improves phase margin and linearity of the active element. The performance of the proposed block has been verified by using Mentor Graphics Eldo simulation tool with TSMC CMOS 0.18 µm process parameters. A new biquad filter is also realized using single VDBA. The three standard filter functions like band pass, high pass and low pass can be realized without changing the circuit topology. All applications are verified with their simulation results. The circuit of SSF based VDBA is quite small and compact. The ac simulation results of complete VDBA show that GBW is 950 MHz and power consumption is 0.45 mW.
