ABSTRACT: Physical design is process of transforming RTL netlist into a layout which is manufacture-able [GDS or GDSII]. An efficient physical design flow is typically divided into five major steps: floorplanning, placement, clock tree synthesis, routing and timing closure. Power optimization is always one of the most important design objectives in modern nanometer IC design. System clock signal in electronics product consumes the important part of dynamic power, among them 70% is spent by clock buffers. This critical problem can be optimized using a technique namely clock gating. Recent studies have shown that applying MBFF is an effective means in reducing clock network power. This paper uses MBFF technique to optimize dynamic power and later clock gating on the same design to achieve better results. The aim of this project is to converge the Server SoC Partition and implement low power techniques such as MBFF and clock gating, to reduce power without degrading timing to a great extent.

Keywords: MBFF; clock gating, dynamic power; power reduction; low power;

ABSTRACT: As communications technology is ubiquitous, and energy savings are ever more crucial in communications and data storage infrastructures, it is timely to revisit the technologies used for energy storage. Thismultidisciplinary paper especially focusses on the specific requirements onto energy storage for communications and data storage,derived from traffic, climate, high availability, and resilience, irrespective from energy sources used. It also addresses techno-economic, environmental &emissions tradeoffs offered by a model, and concludes with discussing future energy storage technologies

ABSTRACT: Ration card plays a vital role for the household details such as to get gas connection, family member details; it acts as address proof etc. In this regard, we have wished for a smart measure card system using Face Recognition Technique and IOT to thwart the derelictions and corruption in the current ration distribution system. In this system conventional quota card will be replaced by a Face Recognition system. This Faces will be verified with family members for authentication of the user. If user is found to be authentic then monthly quota of the ration available for the user is displayed. After successful transaction the database will be updated stating the ration content delivered to the user. This system will require very less human efforts for operation and is also very secure. By implementing this system government can keep track of all the delivered ration content very easily.

ABSTRACT: The paper presents the research results of building a remote monitoring system of independent power stations in rural and mountainous areas in Vietnam, where there is no electricity and telephone reception. Wireless communication technologies were considered and LoRa was chosen. Monitoring system model includes monitoring station at independent power station and remote monitoring station. At the independent power stations, power parameters are measured for on-site display and sent via the LoRa protocol to the central monitoring station. The central station receives signals from independent stations and displays the operating status of these stations. Experimental models were built and tested in Vietnam Academy of Science and Technology..
