when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...

A source-channel matched layered space-time d iwsi ty technique is presented for reliable delivery of lay er coded multimedia data through wireless channels. The transmission system is transformed t o multiple subchannels and each associated with different div ersity gain, therefore different error performance. Similarly to the parallel transmission proposed for ADSL[9], we develop a parallel t...

A synthesis of cat auditory cortex (AC) organization is presented in which the extrinsic and intrinsic connections interact to derive a unified profile of the auditory stream and use it to direct and modify cortical and subcortical information flow. Thus, the thalamocortical input provides essential sensory information about peripheral stimulus events, which AC redirects locally for feature ext...

This paper presents a decentralised Admission Control (AC) algorithm, based on the centralised proposed in [1–4]. Our algorithm is a multiple criteria AC algorithm, where each user can specify the QoS metrics that interest him/her, and decides whether a new call should be allowed to enter the network based on measurements of the QoS metrics on each link of the network before and after the trans...

Noise in an ac biased junction. Non-stationary Aharonov-Bohm effect. Abstract We study excess noise in a quantum conductor in the presence of constant voltage and alternating external field. Due to a two particle interference effect caused by Fermi correlations the noise is sensitive to the phase of the time dependent transmission amplitude. We compute spectral density and show that at T = 0 th...

The present paper aims to investigate the coupled nonlinear Schrödinger equation in magneto-optic waveguides having anti-cubic (AC) law nonlinearity. solitons secured with AC nonlinearity are extremely useful fiber-optic transmission technology. Three constructive techniques, namely, $$(G^{\prime }/G)$$ -expansion method, modified simple and extended tanh method utilized find exact soliton solu...

In this paper, an understanding of reactive power associated with power transmission networks is developed. To make transmission networks operate within desired voltage limits, methods of making up or taking away reactive power— hereafter called reactive-power control—are discussed. Before proceeding further, however, a thorough understanding of the reactive power in ac systems is necessary. Th...

For long distance and high power transmission, high-voltage direct current (HVDC) transmission is a preferred solution due to its technical and economic advantages. A multi-terminal HVDC (MTDC) transmission system either based on voltage source converters (VSC) or line-commutated converters (LCC) has also been introduced recently. With the development of fast and high breaking capability HVDC c...

A novel integrated optimization method is proposed to combine both generation and transmission line expansion problem considering bus voltage limit. Most of the existing researches on the combined generation and transmission expansion planning cannot consider bus voltages and reactive power flow limits because they are mostly based on the DC power flow model. In this paper the AC power flow mod...

Tau protein was scanned for highly amyloidogenic sequences in amphiphilic motifs (X)(n)Z, Z(X)(n)Z (n ≥ 2), or (XZ)(n) (n ≥ 2), where X is a hydrophobic residue and Z is a charged or polar residue. N-Acetyl peptides homologous to these sequences were used to study aggregation. Transmission electron microscopy (TEM) showed seven peptides, in addition to well-known primary nucleating sequences Ac...
