Voice is most prominent and primary mode of communication among of human being. Voice has potential of being unique and important mode of interaction with computer. This paper aims to identify a person through voice and card for bank locker security. A Voice recognition system is designed to identify an authorized person voice and Resistive card for unique id. Proposed work aims at providing two levels of security to user with respect to card and voice. For the result of testing the system, it successfully recognizes the specific user's voice and rejects other user voice. Using this method the accuracy of whole system is successfully maintained in recognizing the user's voice. And for further security purpose GSM sends a message to the user as authorized person or unauthorized person and wireless camera keep on monitoring as live video stream. After accessing voice and card of authorized person bank locker will be opened. If in case any of voice or card is not recognized, buzzer alerts an alarm.

This paper presents the expansion of power quality for variable speed Wind Power System (WPS) using Permanent Magnet Synchronous Generator (PMSG) and Trans Z-Source Inverter. The PMSG is having compact collection and dimensions, compare to Induction Generator. Induction Generator needs the grid power, then only start the power production. But without take up the grid power PMSG should produce the power. The impedance-source (Z-source) inverters idea to the Transformer-based Z-Source Inverter (Trans-ZSI) is implemented. The unique Z-Source Inverter (ZSI) employs an impedance network of two inductors and two capacitors coupled in an exceptional preparation to accessing the dc source. In the proposed Fuzzy Logic Controller (FLC) based trans-Z-Source Inverters, the entire impedance networks structure consists of a two transformers and capacitor. While maintaining the major quality of the earlier accessible Z-source network, the new networks demonstrate some unique compensation, such as the enlarged voltage gain, compact voltage stress, privileged inversion capability and very less harmonics content. Key-words:-Wind Power System (WPS), Permanent Magnet Synchronous Generator (PMSG), Transformerbased Z-Source Inverter (Trans-ZSI) and Fuzzy Logic Controller (FLC).

Small scale stand alone wind generators are a significant different source of electrical energy.Unluckily, most of these systems do not capture more power at every wind speed.Particularly, at low wind speeds which are provide low power.To address this problem, this paper has been proposed a permanent magnet synchronous generator (PMSG) and Zsource inverter.This generator is connected to the power network by means of a Z-source inverter.Permanent-magnet synchronous generators are having some amazing characteristics such as with a reduction of burden and level, advanced performance, minimized size of gear box and no need of external power in permanent magnet excitation.The PMSG defeat the all other generators, marvelous performances without absorb the grid power.This paper presents a Z-source inverter that can be proposed as an option power conversion concept for variable speed wind turbines.It consist both buck and boost capabilities as they permit the inverter to perform the shoot through state.It utilizes a special Z-source network (L-C network) to DC-link in between inverter and the DC source.By controlling the shoot-through duty cycle of IGBTs in inverter system, we can diminish the line harmonics, develop power factor, and enlarge output voltage range.

These requirements force us to re-examine the fundamental assumptions underlying the current integrated circuit manufacturing practice. We review one promising alternative which satisfies many if not all of the requirements of the integrated circuit manufacture of the coming decade. The continuous processing of silicon wafers in a controlled environment, often dubbed ‘factory-in-a-bottle’, promises to move us from the mass manufacturing mindset to a lean manufacturing mindset which has the potential of flexibility, reliability, and profitability without relying on the size of the silicon fabrication line.This paper is based on a talk by C.K.N.
