The truth is balance. However the opposite of truth, which is unbalance, may not be a lie. Susan Sontag, US author and critic (1933–xxxx). If balance is truth, homeostasis is its biological expression. Students learn the importance of homeostatic regulation in the first few lectures of any physiology course. Research scientists may spend their entire careers defining the mechanisms that underli...

With the large-scale distributed PV connected to grid, random and intermittent nature of output, non-linearity inverter, as well low daytime base-load back feeding cause outstanding power quality problems such overvoltage, three-phase unbalance, high harmonic content at end supply system, which seriously affects safe stable operation grid efficiency. Based on residual capacity this paper invest...

Disturbances and model uncertainties often have large impact on model based fault detection and isolation (FDI) processes and result in false alarm or reduced fault detection rate. In rotor systems exited by unbalances, the predominant disturbances (e.g. unbalance forces) and model uncertainties caused by gyroscopic effect appear in a sinusoidal form with rotor rotary frequency. If the influenc...

Dynamic current and transition energy unbalance resulting from parameter mismatch between parallel MOSFET branches are mapped over wide operating ranges. Unbalance generator magnitudes are given for HEXFET Power MOSFET data sheet ant typical production batch extremes. Limit functions are defined for unbalance due to ON resistance, gain and threshold voltage mismatch. Q loci are utilized for map...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Energy is the main constraint for nodes powered by batter, in Wireless Sensor Network (WSN), which can’t be replace latter once deployed. To extend the network lifetime, hierarchical routing is employed. In this paper we aim to improve network life...

The unbalance of an intersecting family F is defined as |F|−d(F), where d(F) is the maximum degree of F ; the max |{F ∈ F : x ∈ F}| over all vertices x. We show that the unbalance of a k-uniform intersecting family is at most ( n−3 k−2 ) when n ≥ 6k3 and we determine all families achieving this bound.

Aiming at the problem of low resources utilization rotating blades in selection process aeroengine fan rotor blades, this paper takes first-order bending dispersion, torque and gravitational moment difference as criteria minimum remaining optimization goal. An intelligent algorithm based on collocation degree is proposed achieves efficient full blades. multiple installations adjustments assembl...

This paper presents the characterization of power control in WCDMA systems. We know that CDMA is an interference limited system. It is shown that the unbalance scheme is reliable and successful for both 2-way and 3-way soft handover. Unbalance scheme minimizes interference and speed up the soft handover algorithm to support more users quickly. Furthermore it requires minimum time to make decisi...
