The carrying capacity is well identified tool to manage problems due to uncontrolled tourism for any destination. This report highlights the carrying capacity estimation of Kerwa tourism area, Bhopal, India. The methodology used in this report is a new two-tier mechanism of impact analysis using index numbers derived from a survey of 123 stakeholders. From this the individual component impact a...
Electric energy passes through many stages from production to usage, and electrical connections take place at these stages. Electrical are quite important for system safety quality. In this study, current-temperature relationship in the cable was investigated joints made with screw connection terminals, depending on torque applied screw. numerical solution of problem, Comsol Multiphysics progra...
The aging of insulating materials can be estimated by an electrical breakdown occurring in electrical components so that the relationship between lifetime, failure probability and reliability of electrical components may be studied using the life models in high voltage cables networks. In last decades with attention to higher features as electrical, thermal, mechanical characteristic, widely cr...
The natural, prehuman abundance of most large predators is unknown because of the lack of historical data and a limited understanding of the natural factors that control their populations. Determining the supportable predator biomass at a given location (that is, the predator carrying capacity) would help managers to optimize protection and would provide site-specific recovery goals. We assess ...
Thin fibers of cross-linked polyacrylate gel were prepared by inducing polymerization reaction inside long glass or Tygon tubings. By immersing these gel fibers in salt solutions containing both Ca(2+) and Na(+) at varying ratios, a discontinuous transition from the swollen state to the shrunken was demonstrated. A very sharp boundary was observed between the swollen and shrunken portions of th...

The article considers the problems of magnetic field distribution, generated by a power electric cable at micro-tunnel-boring shield arrangement site numerical modeling with further full-scale device model experiment. impact foreign sources on readings three-component sensors was established in process study. considerable existence parasitic noises, conditioned external fields and high sensitiv...
We study the formation and propagation of a normal zone in Rutherford-type superconducting cables. We use a rectangular conductor model to account for the electric current redistribution process between the multifilamentary strands in the presence of a normal zone. We obtain and integrate numerically the diffusion equations for the temperature and the current density distributions. Our simulati...
The article describes information network and CATV applications, backbone network structure. Cable is a natural network for carrying high-capacity, bandwidth intense information. In the age of analogue program signals, cable’s capacity was a natural transmission media for broadcast colour TV and high-fidelity stereo sound programs. In the new digital program signal age, cable’s high capacity is...
To prevent accelerated thermal aging or insulation faults in cable systems due to overheating, the current carrying capacity is usually limited by specific conductor temperatures. As heat produced during operation of underground cables has be dissipated environment, actual a power system primarily dependent on properties surrounding porous bedding material and soil. investigate dissipation proc...
