Diminishing the Requirement of Power using PLC and SCADA system in Power grid system
No full textPower management is an important constraint in the design of various loads in industries for automation. So if power consumption increases then the substation monitoring is very important for the purpose of controlling the hardware and software optimization with the help of PLC ladder logic system and SCADA were used. This technique in order to reach strong conclusion about their actual impact on the power grid monitoring and control without manpower. The basic idea behind substation control project is to monitor the switchyards in substation. In substation many relays and circuit breakers are used. When any one breaker is trip because of the problems, we can monitor and control through SCADA windows. In power management project, the computer is used for assigning the priority for various loads. The signals are given to the computer of the electricity board where there is the electronic control unit which controls the sequence of disconnecting the load. On basis of controls from the computer the breakers are managed and in computer the SCADA system is installed which is used for monitoring and control. If there any problem occurs in plant, we can easily identify which part is trip.Afterthat we can troubleshoot the problem through manpower and monitor the substation
IIR filter design using CSA for DSP applications
No full textIn this paper, a design methodology to implement low-power and high-speed 2nd order recursive digital Infinite Impulse Response filter has been proposed. Existing IIR digital filters have a large number of constant multiplications. The proposed method replaces constant multiplications by using addition/subtraction and shift operations. The proposed new adder cell is used as the Carry-Save Adder to implement addition/subtraction operations in the design of recursive section IIR filter to reduce the delay. Furthermore, high level algorithms designed for the optimization of the number of CSA blocks are used to reduce the complexity of the IIR filter. The microwind tool is used to generate the schematic of the proposed CSA based shift-adds architecture design and it will be analyzed by using Micro wind CAD tool to synthesize low-complexity and high speed IIR filters. The proposed design reduces power, propagation delay, area and increase throughput when compared with the existing technology
Attack Resident visually Authenticated and Secured System
No full textKeylogging or keyboard capturing is the activity of recording (or logging) the keys struck on a keyboard, normally in a secretive way so that the individual utilizing the keyboard is unconscious that their activities are being observed. It likewise has exceptionally authentic uses in investigations of human-computer interaction. There are various keylogging techniques, extending from hardware and software based methodologies to acoustic examination. Including human in authentication protocols, while guaranteeing, is not simple in light of their restricted capacity of calculation and remembrance. We exhibit how careful visualization outline can improve the security as well as the convenience of authentication. We propose two visual authentication protocols: one is a one-time-password protocol, and the other is a password-based authentication protocol. Our approach for genuine arrangement: we had the capacity attain to an abnormal state of ease of use while fulfilling stringent security necessities

No full textPain is a highly unpleasant sensory and emotional experienceTonsillectomy is a very common day care procedure that is associated with significant postoperative painlack of pain management can lead to delays in oral intake of patients, resulting in extended stays and increased costs , sometimes dehydration.28 patients (age group 5 to 35yr) assigned for tonsillectomy. The study conducted at Otorhinolaryngology department, MBS Hospital Kota, from August 2010 to August 2011.The present prospective comparative study is designed to evaluate the post operative analgesic efficacy of pre-tonsillectomy peritonsillar infiltration using tramadol, ketamine, xylocaine–adrenaline combination & normal saline as a control
Frequency Regulation Based on Meme Technique in Power Generation
No full textBy improving the frequency regulation in power generation is the new tasks to the operation of power systems. Incompetence of these resources in providing inertial, primary and secondary frequency responses is one of the significant challenges. In this paper, the proposed method of memetic algorithm controls the problem of frequency deviation within the limit using the IEEE six bus system. The result indicates of proposed method that the frequency is regulated within the limit in wind/thermal power generation into power systemsand there is a comparative study of the frequency output with existed technique
Optimal allocation of PMU considering controlled islanding of power system using hybrid optimization algorithm
No full textThis paper proposes an optimal allocation of phasor measurement unit (PMU) placement model under controlled islanding of power system such that the power network remains observable under controlled islanding condition in addition to normal operation condition. The optimization objective of proposed model is to reduce the number of installed PMUs by using hybrid optimization algorithm. The objective is pooled together with a weighting variable such that the optimal solution with less PMU number would be achieved from the model. To decrease the number of required PMUs, the significance of zero-injection bus is considered and incorporated into the model. IEEE standard systems used to test the presented model. Results are presented to exhibit the effectiveness of the proposed technique
A system of piezoelectric cantilevers and accelerometer for on-body energy harvesting
No full textOver the past two decades, there has been significant interest in converting mechanical energy from human motion into electrical energy. This electrical energy can then be used to Recharge batteries in electronic devices or directly power small scale, low-power circuits. A number of commercial devices use human power to produce Electricity such as hand-crank generators and pedal Generators. However, these generators require concentrated human effort for long periods of time, which might preclude the User from doing other tasks. It is desirable to scavenge or harvest Energy from human movement, while the user is performing his/her everyday activities. Some of the earliest work to harvest energy includes the modern electromechanical self-winding watches, and various shoe mounted Foot cranks driven by the potential to power small, portable electronic devices. This paper focuses on harvesting the vibration generated during human motion into electrical energy that can be used to power electronic devices like mobile phone, flashlights, et
Dual-Tox 7T SRAM Cell Design for Leakage Power Reduction on 45nm Technology
No full textThis paper presents techniques based on dual oxide thickness assignment to reduce the leakage power of SRAM but maintaining their performance. The proposed a new seven transistors (7T) dual oxide thickness SRAM cell is proposed in this paper for simultaneously reducing the active and standby mode power consumption while enhancing the data stability and the read speed. With the new 7T SRAM cell, the storage nodes are isolated from the bit lines during a read operation, thereby enhancing the data stability as compared to the standard six transistors (6T) SRAM circuits. The transistors of the crosscoupled inverters are not on the critical read delay path with the new technique. Minimum sized dual-oxide thickness transistors are therefore conveniently used in the cross-coupled inverters for significantly reducing the leakage power consumption without causing degradation in the read speed. With the proposed 7T SRAM circuit, the static noise margin and the read speed are enhanced by up to 83% and 15%, respectively, as compared to the conventional 6T SRAM circuits. Furthermore, the leakage and the write power consumptions of the proposed dual-Tox SRAM circuit are reduced by up to76% as compared to the conventional6T SRAM circuits in a 45nm CMOS technology
