A Comprehensive Review on the Business Strategy and the Policy based Reforms Adopted in the Search of a Sustainable and Reliable Power Supply System in India
No full textThe primary reasons for power sector reform are different in developed and developing countries. The main driving force for power sector reform in developed countries are to realize efficiency gains in the generation and distribution segments, which are made possible through technological innovations. But the main driving force in developing countries, including India, seems to be to attract private sector investment in the power sector. Promoting private participation by facilitating incremental investment, felt not sufficient to bring reform; hence policy reforms for appropriate business environment was included. As a result, changes in business strategy also took a key role along with the policy changes. Various forms of business models for generation as well as distribution evolved across Indian power sector. This article describes the journey of Indian power sector to the context of the adoption of business strategy and policy based reforms, during different eras of time.
Ultrasound Irradiated Polymerization of Styrene under Heterogeneous Condition-A Kinetic Study
No full textThe kinetics of multi-site phase-transfer catalyzed free radical polymerization of Styrene (STY) using potassium peroxy disulphate (PDS) as water soluble initiator and newly synthesized 1,4-dihexadecylbenzopyrazine-1,4-diium dibromide as multi-site phase-transfer catalyst (MPTC) has been investigated in ethyl acetate / water two phase system at constant temperature 65 + 1°C under nitrogen atmosphere and ultrasound irradiation conditions. The rate of polymerization increases with an increase in concentrations of STY, MPTC and PDS. The order with respect to monomer, initiator and MPTC were found to be 2.0, 1.0 and 0.5 respectively. Based on the observed results a suitable mechanism has been proposed to account for the experimental observations and its significance was discussed
Restoring Damaged Images by Region Filling and Object Removal using Image Inpainting and Deconvolution Algorithm on Virtual Instrumentation Platform
No full textImage inpainting refers to the process of filling-in missing data in a designated region of the visual input. The object of the process is to reconstruct missing parts or damaged image in such a way that the inpainted region cannot be detected by a casual observer. Applications of inpainting range from the reconstruction of missing blocks introduced by packet loss during wireless transmission, reversing of impairments such as cracks, scratches, and dirt in scanned photographs and digitized artwork images and removal/introduction of image objects such as logos, stamped dates, text, persons, and special effects on the scene. Typically after the user selects the region to be restored, the inpainting algorithm automatically repairs the damaged area by means of image interpolation
Overview of Zigbee as a Wireless Communication System
No full textZigbee is a wireless technology which was developed by the Sigbee Alliance to cover some sort of limitation of BLUETOOTH and Wi-Fi. It is an IEEE 802.15.4 standard for data communication purpose in business and consumer devices. It is designed such that it uses low-power which allowing batteries to essentially last forever and long battery life. Basically the BLUETOOTH was developed to replace wires for communication and Wi-Fi to achieve high data transfer rate, but after these two wireless technology till now nothing has been developed for sensor networking and for controlling of l machines without wires which require longer battery life and do continuous working without human intervention in controlling of machine. Zigbee device allows batteries to last up to years using primary cell (low cost) without any chargers (Low cost and easy installation)
Implementation of Automatic Functional Testing Tool Using CanSniff for Automotive Applications
No full textThe goal of this work is to create a Test Tool that automates all of the manualwork. By using this tool, one can actually create and run test casesautomatically. This tool automatically reads the commands for read/writeShadow Variables, Application Variables, Application Cans, physical signals,etc. from the specified file and executes the required commands without anyuser intervention, and hence helps to automate the entire process of manuallytesting every step. Using the CanSniff tool, one can actually read/write thecontents of a memory (EEPROM) location within an ECU. This tool alsoallows the user to include delays before executing any command therebyproviding time to the user to observe things of how they are working out.This tool also integrates one more tool called “Harness Configuration Utility”,which has the functionality to map the controller pins to the hardware andprovide alias names to the mapped pins. It also has a scaling function whichprovides a conversion of physical units to engineering units
A Survey Report on Operating Systems for Tiny Networked Sensors
No full textWireless sensor network (WSN) has attracted researchers worldwide to explore the research opportunities, with application mainly in health monitoring, industry automation, battlefields, home automation and environmental monitoring. A WSN is highly resource constrained in terms of energy, computation and memory. WSNs deployment ranges from the normal working environment up to hostile and hazardous environment such as in volcano monitoring and underground mines. These characteristics of WSNs hold additional set of challenges in front of the operating system designer. The objective of this survey is to highlight the features and weakness of the operating system available for WSNs, with the focus on current application demands. The article also discusses the operating system design issues in terms of architecture, programming model, scheduling and memory management and support for real time applications
Virtual Instrumentation Approach for Client-Server Interfacing of Bluetooth Using LabVIEW
No full textBluetooth is one of the most widely wireless ad hoc networks used. Bluetooth devices operate at 2.4GHz, in the globally available, license-free, ISM band and they use FH-CDMA technique because of its inherent interference rejection capability. The problem with Bluetooth is low date rate and distance between the devices is less. In this article we will discuss how the communication is done in lab view with Bluetooth through client server application. As LabVIEW is good for communication between the devices as it has many communications protocol features built in it. When you are actually writing the application, you have more flexibility in choosing a protocol. Factors that affect your protocol choice include the type of machines the processes will run on, the kind of hardware network you have available, and the complexity of the communication that your application will need. Several protocols are built into LabVIEW, some of which are specific to a type of computer
Application of Vedic Mathematics for fast computation in DSP based Power System Protection and Monitoring
No full textThe primary objective of a power system is to deliver power continuously despite disturbances. It is crucial that a power system is protected from contingencies. For this purpose, several protection schemes are employed out of which numerical relays embedded with digital signal processors (DSP) are able to improve the protection operations significantly. Such relays are capable of performing large number of complex computations in relatively short time. Real time signals such as voltage and current are converted from analog to digital by the use of ADCs & several operations are performed on the sampled data. One such important operation is the extraction of the fundamental frequency component of the sampled signal from which the orthogonal values are extracted to serve as an indication for the relay tripping system. Several methods exist for this purpose, one among which is the Discrete Fourier Transform (DFT). The DFT can extract any required harmonic and provide the quantities required for the tripping algorithm. However, the DFT is a time intensive process due to the large number of multiplications and additions. This article presents a method of using Vedic mathematical algorithms to perform computations in lesser time, i.e. with a reduced delay
Design flow of the Hardware-in-Loop Testing & Interactive Calibration
No full textHardware-in-Loop is a form of real time simulation. Hardware-in-Loop differs from pure real time simulation by the addition of a “real” component- ECU in the loop. The current definition of Hardware-in-Loop says that the plant is simulated and ECU is real. ECU is a physical unit with number of sensors and actuators attached to it. The purpose of HIL system is to provide all of the electrical stimuli needed to fully exercise the ECU. In effect, “fooling” the ECU into thinking that it is indeed connected to real plant.
