Nowadays Distribution networks are growing in complex due to the increase in power demand, variation in load and different kinds of load. So these leads to degradation of quality power to the consumers. The efficient Operation of Distribution networks can be achieved by reconfiguring the network for reducing the line losses and for improving the system reliability. IHSA (Improved Harmony Search Algorithm)...
Code smells are a metaphor to describe symptoms in the code that may provoke maintainability problems. Code smell detection and remove have a closer relationship to refactoring which has been a well-known and disseminated practice for improving software maintenance and reuse. In 2013 a study for knowing about the position and knowledge of developers was conducted from Norway. This study covered developers...
A novel concept instrumentation amplifier (IA) using an analog signal compression technique is suggested to achieve a large dynamic input range. A large analog input signal is segmented into a smaller analog signal to prevent saturating the analog output signal in the input stage of the IA. At the input stage, we apply a reference bias at a node between an input capacitor and an input MOS to function...
In this article work on implementation and studies of algorithm of analog compensating of error from edge effects for sigma-T analog-to-digital converter is carried out.

A row of model experiments is carried out and values of a standard deviation of ADC linear function without compensating and with analog compensating respectively...
We demonstrate a desktop platform which has the ability of modeling ReRAM TiO2 samples in a highly automated manner. The system consists of a bespoke RRAM characterization instrument that hosts packaged RRAM devices and is operated via a PC. The system's python-based software includes a module that automatically applies strategically chosen sequences of pulses to a test device and then extracts the...
In this paper, a versatile, re-programmable, current-input bioinstrumentation board is presented for electrochemical amperometric measurements. The proposed instrument has been fabricated on a six layer printed circuit board (PCB) and exploits dual switched-capacitor (SC) integration and sample-and-hold (SH) techniques. It comprises off-the-shelf switch and amplifier ICs and a commercially available...
Ever since Chinese electric power reform in 2002, different live test approaches were introduced and applied in relative industries. There were at least 26 live test approaches applied in the field of power transformation, power transmission and power distribution. The essay introduced a comprehensive dynamic and flexible effectivity evaluation system, which helped to evaluate the strengths and weaknesses...
Locking Segment Insertion Bits (LSIBs) have been proposed to secure access to on-chip embedded instruments in IEEE 1687 networks. LSIBs can be opened (or closed) only if the correct key value is applied to the LSIB's key logic circuit. Using gate-level simulations previously used for cryptographic circuits, we evaluate the susceptibility of several LSIB key logic designs to simple power analysis attacks...

In that by adding inductance and diode to the input side of power electronic converter the input voltage to be boosted and eliminates the ripples in the input current and reduce the inrush current. In the distributed generating...
Systems on-Chip (NoC) has created as a promising answer for on-chip interconnection in SoC because of its adaptability, reusability, adaptability and parallelism. It is important to identify and rectify the fault in the Network on Chip. Testing is an important process to find and rectify the fault in Network on Chip. In testing, FIFO buffers produce high throughput gain as well as reduce latency....
The need for skilled arthroscopic surgeons is increasing due to the large number of arthroscopic interventions performed annually. Surgical simulators are beneficial training platforms for practicing those difficult to learn surgical tasks. In this study, a sensorized physical shoulder simulator was developed. This simulator incorporates switch sensors for objective assessment of probing tasks and...
This paper describes a phase switching algorithm for Interpolating Digital-to-Analog Converter (DAC) based Arbitrary Waveform Generators (AWG). This was possible by using the standard phase switching algorithm with the addition of simple phase offset and systematic phase difference adjustment; this was discovered by experimenting with suppression of the intermodulation distortion (IMD) components...
Reverse recovery parameter (RRP) characterization is a vital process in the modeling of LDMOS devices. This paper presents the validation of a RRP characterization setup to assess its adherence to the JEDEC JESD 24-10 standard when used on high-speed LDMOS devices. Circuit performance is exhaustively evaluated using both, packaged and wafer-level devices. Aspects that include switching speed, repeatability,...
This paper describes a capacitive programmable-gain amplifier (CGA) with amplifier common-mode sampling (CMS) and switched-capacitor driving capability, compatible with many conventional switched-capacitor ADC inputs (SCAI) such as delta-sigma modulators or SAR ADCs. CGAs are popular for their low power, low noise and high precision [1,2]. The capacitive gain network is highly linear, does not dissipate...

Digital lock-in amplifiers are largely used to perform high-resolution measurements in different scientific fields. The experimental evidence shows that state-of-the-art, high frequency commercial models do not allow to measure signals with a resolution better than few tens of ppm due to additional signal-proportional 1/f noise observed on the lock-in output. This noise arises from low-frequency gain...
