It can motivate customers to change their consumption patterns according to the dynamic(time-varying) electricity price, which is considered to be the most cost-effective and reliable solution for smoothing the demand curve. However, many existing schemes, based on users' demand request in each period, require users to consume their requested electricity exactly, which sometimes causes inconvenience and losses to the utility, because customers cannot always be able to consume the accurate electricity demand due to various personal reasons. In this paper, we tackle this problem in a novel approach. Instead of charging after consumption, we adopt the prepayment mechanism to implement power request. Furthermore, we propose a trading market running by the control center to cope with the users' dynamic demand. It is noteworthy that both users' original demand and trading records are protected against potential adversaries including the curious control center. Through the numerical simulation, we demonstrate that our scheme is highly efficient in both computation and communication.展开更多

Three Egyptian nuclear research centers and the proposed nuclear research center have been studied. These centers are the Nuclear Research Center in Inshas, the Hot laboratories and Waste Management Center in Inshas, the National Center for Radiation Research and Technology in Nasr City and the proposed Nuclear Research Center in North Western Coast of Egypt. Also, the paper aims to study the functions of these centers, as well as the types of their existing facilities. The paper investigates the principles and standards used in design and planning of these nuclear research centers. A comparative study has been conducted to those four nuclear research centers to evaluate the centers according to the site characteristics and the basic safety factors. The results were compared to determine the best design and planning. The proposed Nuclear Research Center in North Western Coast of Egypt proved to be the best among all with regard to design and planning, taking into consideration the radiation safety requirements. The architects are recommended to design and plan the nuclear research centers, taking into consideration the radial planning concept because it is the best with regard to radiation safety requirements.展开更多

The construction of the study is composed by following aspects. The first aspect is the modelling of a structural system. As a typical example, a mega frame-core-tube structural system adopted by some famous super tall buildings such as Taipei 101 building, Shanghai World financial center, is employed to demonstrate the modelling of a computational model. The second aspect is the establishment of motion equations constituted by a group of ordinary differential equations for the analyses of free vibration and resonant response. The solutions of the motion equations （that constitutes the third aspect） resorted to ODE-solver technique. Finally, some valuable conclusions are summarized.展开更多

As an application, the center problem and the isochronous center problem of a particular system are considered. They show that the system has a center at the origin if and only if the first seven Liapunov constants vanish, and cannot have an isochronous center at the origin.展开更多

The pre- cise role of exon 1-encoded N-terminal domains and how these influence the biological functions of human HtrAZ remain elusive. In this study, we traced the evolutionary origins of these N-terminal domains to a single gene fusion event in the most recent common ancestor of vertebrates. We hypothesized that human HtrA1 is impticated in unfotded protein response. ｜n highly secre- tory cells of the retinal pigmented epithelia, endoplasmic reticulum （ER） stress upregulated HtrA1. HtrA1 co-localized with vimen- tin intermediate filaments in highly arborized fashion. Upon ER stress, HtrA1 tracked along intermediate filaments, which collapsed and bundled in an aggresome at the microtubule organizing center. Gene silencing of HtrA1 altered the schedule and amplitude of adaptive signaling and concomitantly resulted in apoptosis. Restoration of wild-type HtrA1, but not its protease inactive mutant, was necessary and sufficient to protect from apoptosis.
