Abstract:

The losses in the power system vary the gap between energy supply and demand. Among these losses, the distribution system has major contributions compared to the transmission system. This paper thoroughly examines the PESCO distribution losses and implements a practical approach that forties in the loss’s minimization. Using the bifurcation and restoration strategies, the PESCO distribution system can be well-organized and an effective system can be designed. The proposed approach also helps in estimating the entailed capital investments and the rate of return over time. Both the HT (High Tens

Abstract:

The Low Temperature Phase (LTP) content determines the spontaneous magnetization Ms of the rare-earth-free hard magnetic material MnBi. LTP in MnBi samples alloyed by the arc-melting is timely developed when they are annealed at the annealing temperatures Ta < 340 oC. Because of the complexity of the phase diagram of MnxBi(100-x) system, the content hardly reaches the value of 100 wt%. Based on the phase diagram of MnxBi(100-x) system, the upper limit * was calculated and 59.8 wt% is the highest content which can be reached when the alloy is isothermally annealed for a long time.

Abstract:

Lightning strikes on airborne transmission networks such as in distribution lines are injections of electric charge. The injection of the charge will cause a voltage increase in the network, so that more tension will arise in the network. Lightning Arrester (LA) is one of the equipment in the protection system to protect the 20 kV distribution transformer against overvoltage coming from lightning strikes. Under normal circumstances LA acts as an insulator, but when exposed to lightning strikes LA will function as a conductor whose resistance is relatively low, so that it can flow the surge cur

Aims and Objectives: Motor control is described as the internal control and regulation processes which facilitate movements. Scientists divide motor control into the function of stability and the movement to maintain balance in locomotion. The FMS is used to analyze the motor behavior of muscle slings on the one hand, and to estimate injury risk on the other hand. Yet, the true extent of the FMS’ diagnostic information remains unclear. The low intensity level of the FMS items causes low tension within the motor network. Based on Hennemen’s size principle, this is a clear indicator for the acti

The radiation-thermal stability of extraction mixtures based on methyltrioctylammonium carbonate has been studied.

The use of switchgrass (Panicum virgatum L.) as an energy crop has gained great importance in past two decades due to its high biomass yields on marginal lands with low agricultural inputs and low maintenance requirements. Information on the allocation of photosynthetically fixed C in the switchgrass-soil system is important to understand the C flow and to quantify the sequestration of C in soils. The allocation of <sup>13</sup>C labeled photosynthates in shoot, root, soil, and in microbial biomass carbon (MBC) of rhizosphere and bulk soil of 45 days old, greenhouse grown-switchgra

Aims. The distribution of neutral hydrogen in the intergalactic medium (IGM) is currently explored at low redshift by means of UV spectroscopy of quasars. We propose here an alternative approach based on UV colours of quasars as observed from GALEX surveys. We built a NUV-selected sample of 9033 quasars with (FUV−NUV) colours. The imprint of HI absorption in the observed colours is suggested qualitatively by their distribution as a function of quasar redshift. Methods. Because broad band fluxes lack spectral resolution and are sensitive to a large range of HI column densities a Monte Carlo sim

Increasing the concentration of nanoparticles reduces the interfacial tension and surface tension of SDS at low surfactant concentration (< cmc) but it has a minor effect on interfacial and surface tension of C12TAB. Repulsive columbic interactions between SDS molecules and nanoparticles can cause the higher adsorption of surfactant at the oil/water int

Field investigations have been carried out covering spectrum of loads and voltage levels right from generation to consumers, as at present.

Traction loads are another major category of harmonic pollutant. Industrial consumers do provide reactive compensation which helps to filter out current harmonics partially. However,

Prolonged conventional water flooding leads to predominant water channels, resulting in water channeling and limited sweep efficiency. Surfactant flooding is usually adopted in these conditions because it can mitigate water channeling and enhance sweep efficiency by l

The twisting of yarn in one of the most widely used conventional ring spinning processes is based on the ring/traveler system. The existing limitation of productivity in the ring spinning process lies on the prevailing force relation between ring, traveler and yarn as well as the frictional heat between traveler and ring, principally in the ring traveler system. Recently, a frictional free twisting element based on a superconducting magnetic bearing (SMB) was developed to increase the productivity of ring spinning drastically, which was patented by ITM and Leibniz IFW Dresden.
