Efficient implementation of full adder for power analysis in cmos technology
In recent days, the real-time application and fast arithmetic operations require highly efficient arithmetic hardware
architecture to improve the system performances. The adder plays a vital role in digital circuits, the earlier hardware
architecture using conventional CMOS and transmission logic gate based full adder design. Moreover, the techniques using
more number of transistors and consume larger power and delay so we proposed the techniques pass-transistor logic and
transmission gate based hybrid pass logic. The hybrid technique is used to reduce the number of the transistor, so the delay
and power consumption will be reduced when compared with the earlier techniques. The proposed technique design was
implemented using 16 transistors in 180nm CMOS technology and it consumes 8.2075nW power and the delay reduced to

This document provides calculations to determine the minimum possible supply voltage (Vcc) for a push-pull amplifier. It is given that the amplifier must deliver 40W to an 8Ω load using a transformer with 160 primary turns and 40 secondary turns. Using the transformer turns ratio and expression for maximum power delivered to the load, the minimum Vcc is calculated to be 50.60V.

FPGA stands for field programmable gate array. FPGAs contain configurable logic blocks that can be connected through connection bars and modified for various applications. FPGAs have different features than ASICs and can be specified using HDL scripts similarly to ASICs. FPGAs provide advantages over ASICs such as shorter design time and lower costs.

The document discusses SRAM cell designs that aim to reduce power consumption. It analyzes conventional 6T SRAM cells and proposes new 7T SRAM cell designs with single bitlines that reduce power by using fewer bitlines while maintaining high read stability and static noise margins. A new triple modular redundancy technique is also proposed using a 4-to-1 multiplexer as a voter circuit to determine the majority output and improve reliability against faults with less layout area than conventional voting circuits.

This document discusses power analysis attacks on cryptographic devices that store sensitive data. It proposes a 7-transistor (7T) static random access memory (SRAM) cell design to provide resilience against these attacks. The 7T cell uses an additional transistor and a two-phase write operation to significantly reduce the correlation between stored data and power consumption during writes. Simulation results show the 7T cell reduces write energy standard deviation by over 1000x compared to a conventional 6T SRAM cell. It also has lower write energy, write delay, and higher static noise margins than other power analysis resistant SRAM cell designs.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
