A steady-state security region is a set of real and reactive power injections (load demands generations) for which the flow equations constraints imposed by equipment operating limits are satisfied. The problem determining regions formulated as one finding sufficient conditions existence solutions to map within constraint set. Explicit on at each bus obtained, such that if injection lies corresponding limits, system guaranteed operate with

This paper deals with nonlinear networks which can be characterized by the equation ${\bf f}({\bf x}) = {\bf y}$, where f}$ is a continuous piecewise-linear mapping from $R^n $ into itself. The main theorem asserts that existence of solutions x} \in R^n y}$ for an arbitrary given y} guaranteed fairly general conditions based on theory degree mapping. Then it shown iterative algorithm (generalized Katzenelson algorithm) leads to solution in finite number iteration steps. Finally,...

The numerical analysis of the total interaction free energy for predicted quadrilateral array 15nm diameter APTES nanodisks at intervals 100nm would accommodate in each disk under Debye length 14nm. experiments we conducted conformed to theoretical predictions and successfully ATPES without adsorbing SiO2 substrate surface.

ABSTRACT We studied injury of Escherichia coli O157:H7 cells in 11 food items during freeze storage and methods isolating freeze-injured E. from foods. Food samples inoculated with were stored for 16 weeks at −20°C a freezer. Noninjured injured counted by using tryptic soy agar sorbitol MacConkey supplemented cefixime potassium tellurite. Large populations salted cabbage, grated radish, seaweed, tomato samples. In an experiment to detect artificially contaminated cells, the organism was...

In this paper, the recent advances in cooperative distributed antenna transmission (CDAT) are introduced for spatial diversity and multi-user multiplexing 5G mobile communications network. CDAT is an advanced version of coordinated multi-point (CoMP) transmission. Space-time block coded transmit (STBC-TD) minimum mean square error filtering combined with singular value decomposition (MMSE-SVD) described under presence co-channel interference from adjacent macro-cells. Blind selected mapping...

Vacuum-ultraviolet (VUV) radiation damage was investigated in inductively coupled Ar, He, and O 2 plasmas by measuring the hole currents generated SiO film. The strongly depended on irradiated plasma VUV wavelength photon flux (electron density). When electron density increased, larger were observed A of 58.4 nm He 130.5 more holes film than that 104.8 106.6 Ar did. That is believed to be due not only energy but also dependence transmittance films wavelength. We found pulse-time-modulated...

Electrostatic self-aligned positioning of a single 7 nm nanoparticle in the cage-shaped protein ferritin onto an aminosilane disk pattern as large next-generation photolithography can produce is demonstrated. Genetic modification increased its surface charge density and therefore improved electrostatic interaction. Single molecules recombinant could achieve placement on 32–45 disks under optimal solution condition, which was calculated by numerical analysis. This biological placement,...

Accurate channel estimation is essential for broadband wireless communications. Adaptive sparse schemes based on normalized least mean square (NLMS) have been proposed to exploit sparsity improved performance. However, their performance bound as derived in this paper indicates that the invariable step size (ISS) usually used iteration these would lead loss or/and slow convergence speed well high computational cost. To solve problem, observation a large preferred fast while small accurate...

The commercially relevant was achieved by for only 10 minutes and the effect sustains at least one month under an appropriate storage condition. Improved also observed rapa subsp. pekinensis (Chinese cabbage) seeds. device used is simple. No pure gas flow system necessary it easy handle. A large number of seeds be treated simply scaling up...

Biological synthesis and self-aligned placement of a Coulomb island was demonstrated for single electron transistor (SET) fabrication using cage-shaped protein, apoferritin. Homogenous ϕ7 nm Co3O4 In oxide nanoparticles (NPs) were synthesized utilizing the apoferritin cavity as spatially restricted chemical reaction chamber.

By changing the size of incorporated inside cavity, similar structures distinctively different properties can be fabricated.

In a frequency reusing wireless local area network (WLAN), the co-channel interference (CCI) environment will change when new access points (APs) join network. Therefore, user throughput reduces if available channels are not properly re-allocated. A newly joined AP is designed to measure CCI levels on select best channel which experiences lowest (this referred as conventional assignment). However, old APs' anymore since has changed after one joined. If each periodically measures and...
