The developed protection scheme is based on a command-limiting architecture that accounts for aircraft adverse aerodynamics, unusual attitude, and structural integrity and is designed to augment a standard gain-scheduled flight control law. The scheme also includes an energy protection system, which relies on an automatic throttle control loop that implements a total energy control law. In the setup adopted, the limits of the protected envelopes are actively adjusted to ensure, on the one hand, that the aircraft always stays in a safe flight condition and, on the other hand, that the pilot has enough control authority to perform aggressive maneuvers, if needed. Batch simulations demonstrate the efficacy of the protection system in maintaining the aircraft within desired safe conditions. | eng_Latn | 5,002 |
Implications of the choice of interatomic potential on calculated planar faults and surface properties in nickel | With the increasing use of molecular simulation to understand deformation mechanisms in transition metals, it is important to assess how well the simulations reproduce physical behavior both near equilibrium and under more extreme conditions. In particular, it is important to examine whether simulations predict unusual deformation paths that are competitive with those experimentally observed. In this work we compare generalized planar fault energy landscapes and surface energies for various interatomic potentials with those from density functional theory calculations to examine how well these more complicated planar faults and surface energies are captured and whether any deformations are energetically competitive with the {111}⟨112⟩ slip observed in FCC crystals. To do this we examine not just the (111) fault orientation, but also the (100), (110), (210), (211), (311), and (331) orientations to test behavior outside of the fitting range of the interatomic potentials.

The chip information such as the die circuits and current profiles as well as power delivery network circuit can be used at the board level to perform PI analysis. The die current profiles are used to obtain the target impedance. For the complicated package geometry structure, the 3D electromagnetic field solver is used to extract the package power supply model. In order to meet the target impedance, the required decoupling capacitors and location can be analyzed and placed according to the transfer impedance in frequency domain.

The Importance of Inspections on Electrical Installations in Hazardous Locations | Electrical installations in hazardous locations (classified areas) need careful attention because non-conformities can bring considerable risks not only to the site, but also for other industries and residential areas nearby. To assure safe operation of an industrial facility it is necessary not only that all electrical and electronic equipment to be used in hazardous locations is correctly specified and purchased (known as “Ex equipment”), but also properly installed and maintained. The discussion in this paper is largely based upon International Electrotechnical Commission (IEC) standards; however, conceptually the same philosophy applies to American based standards and installations as well. | Abstract We develop narrative futures to analyze the impact that the energy transition may have on the electricity sector's organizational model: re-arrangement, incremental change, or first steps in a paradigm shift.

Prevention--how misuse of a concept undercuts its worth. | Examples are cited to argue that some mass prevention programs have been oversold. The National Cancer Institute and American Cancer Society's promotion of dietary changes to reduce cancer risk has spawned risky diets promoted by food faddists. Overuse of hysterectomy and estrogen replacement therapy and an overzealous swine flu immunization campaign have caused needless mortality and morbidity from complications. Promoting adolescent contraception as a means to reduce child abuse represents an overextension of the idea of preventive health measures into the nonmedical sphere, as do physicians' campaigns that amplify children's fears of nuclear disaster. Public confusion about the distinction between therapy and prevention has been fostered by groups soliciting funds for cancer research, while some health promotion campaigns have contributed to a blame-the-victim mentality and to the imputing of magical powers to certain prevention symbols.

Application of the transverse acoustoelectric effect to studying silicon surface charging upon water adsorption | Water adsorption on a silicon surface in a layered Si-LiNbO3 structure with an air gap is studied using the transverse acoustoelectric effect on surface acoustic waves. A generalized analysis of measurements of the transverse acoustoelectric effect makes it possible to determine the initial band bending of the Si surface, its changes during gas cycles, hence, the sign and charging kinetics of Si upon H2O adsorption. Depending on the properties of the semiconductor surface defects, both the donor and acceptor nature of the interaction of H2O with Si are observed. For samples with a thermal oxide, the donor-type interaction occurs; for samples with a natural oxide, both interaction types take place. Based on the used physical model of oxide charging upon exposure to an adsorbate, a comprehensive methodical approach is proposed, which allows the targeted development of acoustoelectronic structures for sensor applications. | This paper presents design procedures that achieve specifed lightning performance of overhead transmission lines.

Application of electrical resistivity tomography in assessing complex soil conditions | Appropriate assessment of spatial variation of soil and hydrogeological conditions is a crucial issue in recognizing foundation soil.

Effects of high-voltage electrostatic field on the freezing behavior and quality of pork tenderloin | Abstract This study investigated the effects of a high-voltage electrostatic field (HVEF) on the freezing behavior and quality maintenance of pork tenderloin. Based on the freezing behavior of deionized water (DW) under both AC and DC conditions, the freezing of pork samples using DC treatment was examined. It was found that the freezing point ( T m ) and phase-transition time (crystallization time, t c ) of the meat varied with increasing voltage. The water-holding capacity of samples treated by 10 kV exceeded that of the control group, which was proven using low-field nuclear calorimetry (LF-NMR) and differential scanning calorimetry (DSC). The total area of ice crystal for the cross sections of pork tenderloin treated with 10 kV HVEF was much smaller than that without HVEF. Microstructural observations indicated that freezing assisted by 10 kV HVEF was superior to freezing without HVEF in maintaining the quality of frozen pork. | A description of how accurate system modelling of a dc system with an electromagnetic transient simulation program can be used to study and correct interbipole oscillations between converters connected into a parallel multiterminal system is given.

The detail of control models that are used in the electromagnetic simulation programs are shown to have a significant impact, in some cases, on the simulation results. In particular, a case of six hertz oscillations, in the dc currents of two converters on the Nelson River System, is accurately simulated, and it is shown that control modifications suggested by the simulation actually do eliminate the interbipole oscillations. | eng_Latn | 5,031 |

Design of Lightening Protection System for power supply of computer room | It was analyzed the damage of Information Systems and instruments caused by lightning.Combined with the design and implementation of Lighting Protection System for power supply of computer room in information center,the design principle and implementation method was described in detail. | This paper describes an expert systems approach, based on symbolic reasoning techniques, to the problem of predicting radiated EMI levels from printed circuit boards. The expert system, currently under development at the University of Missouri-Rolla, USA, starts by extracting board geometry information from the board layout files. This information is fed into the classification algorithm, which determines the signal properties and nature of each net, using the knowledge stored in the knowledge base. The evaluation algorithm uses the available in formation to identify and evaluate critical circuit geometries, and then estimates the effect that these geometries have on system radiation levels. The expert system also looks for violations of basic EMC design rules. The main advantage of such a system over conventional software is that the expert system does not require the user to be an expert in EMC or circuit design. | eng_Latn | 5,089 |
