Analysis of Stranded Multi-Conductor Cable in Multilayered Dielectric Media
ABSTRACT
Due to complexity of electromagnetic modeling, researchers and scientists always look for development of accurate and fast methods to extract the parameters of electronic transmission cables. These parameters play a critical role in various applications like electro surgery, fault location in cables and many more. In this paper, the modeling of stranded multiconductor cable in multilayered dielectric media is illustrated. We specifically determine the distributed parameters of two wire transmission lines in two-layered dielectric media. The effect of frequency change on the parameters is also discussed. This numerical analysis was successfully implemented for modeling of a cable which connects the hand piece of an electro surgical device to its generator. Comparison of the theoretical and the practically measured results is demonstrated with good agreements.
Effect of mesh grid structure in reducing hot carrier effect of nmos device s...
This paper presents the critical effect of mesh grid that should be considered during process and device
simulation using modern TCAD tools in order to develop and optimize their accurate electrical
characteristics. Here, the computational modelling process of developing the NMOS device structure is
performed in Athena and Atlas. The effect of Mesh grid on net doping profile, n++, and LDD sheet
resistance that could link to unwanted “Hot Carrier Effect” were investigated by varying the device grid
resolution in both directions. It is found that y-grid give more profound effect in the doping concentration,
the junction depth formation and the value of threshold voltage during simulation. Optimized mesh grid is
obtained and tested for more accurate and faster simulation. Process parameter (such as oxide thicknesses
and Sheet resistance) as well as Device Parameter (such as linear gain “beta” and SPICE level 3 mobility
roll-off parameter “ Theta”) are extracted and investigated for further different applications.

A new poling method for piezoelectric ceramics with thick film (1)
A new poling method is proposed for piezoelectric ceramics with thick films that uses ITO glass instead of metal electrodes. Using ITO glass overcomes the constraints of applying high electric fields, which can cause cracking in conventional poling methods. ITO glass allows for higher electric fields during poling due to its high energy band, resulting in better alignment of dipoles and higher piezoelectric constants compared to conventional methods. The article discusses energy band concepts and the advantages of ITO glass for piezoelectric poling.

This document presents a new method for analyzing transient voltage distributions in transformer windings. It models the electric, magnetic, and current fields as equivalent circuits consisting of interconnected electric and magnetic networks.
The electric network models the voltage distribution within each winding section using resistances and emfs derived from the geometry. The magnetic network models the flux paths using reluctances, which is then converted to an equivalent inductance network. Capacitances model the electric fields within and between sections.
The electric, magnetic, and capacitance networks are coupled through ideal transformers to form a single overall mathematical model without mutual inductances. The model can analyze transient voltages inside the windings resulting from any applied terminal overvoltage waveform. An example application
A NEW FULL ADDER CELL FOR MOLECULAR ELECTRONICS
Due to high power consumption and difficulties with minimizing the CMOS transistor size, molecular electronics has been introduced as an emerging technology. Further, there have been noticeable advances in fabrication of molecular wires and switches and also molecular diodes can be used for designing different logic circuits. Considering this novel technology, we use molecules as the active components of the circuit, for transporting electric charge.

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.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

- 4. Why is a magnetic coupled circuit important?
- 5. What is the significance of using DOT convention for coupled circuits? Dot Convention in Coupled Circuits is used to establish the choice of correct sign for the mutually induced voltages in coupled circuits. If two terminals belonging to different coils in a coupled circuit are marked identically with dots then for the same direction of current relative to like terminals, the magnetic flux of self and mutual induction in each coil add together. The physical basis of the Dot Convention in Coupled Circuits can be verified by examining Fig. 10.6. Two coils ab and cd are shown wound on a common iron core.
