Resumen

f the ratio of NPC/H and H bridge hybrid multilevel converters DC supply voltage changed, the output voltage PWM waveform will be discontinuous. Thus an improved topology and control strategy is proposed. In new method, master converter operates at the fundamental frequency based on command voltage, slave converter adopts carrier phase shifted PWM technology (CPS-SPWM) at a higher frequency to enhance the quality of output voltage waveform. The amplitude of command voltage is higher than output voltage amplitude of the master converter at any time, to ensure that output voltage variation of bo

Resumen

Abstract The command “you shall be holy” (Lev 11:44, 45; 19:2; 20:7, 26; Num 15:40) figures into scholarly views on holiness and source criticism. It has been interpreted as evidence for a dynamic view of holiness and as implying that Israel is not presently holy but needs to become holy. The call for Israel to be holy has also been identified as a distinguishing feature of H, a posited strata within the Priestly source. In this article, I examine phrases in the priestly writings that contain verbal uses of קדש and predicate uses of both the nominal and adjectival forms of קדש to demonstrate t

Resumen

Eight multigroup segregation indices are decomposable into a between and a within term. They are two versions of 1) the mutual information index, 2) the symmetric Atkinson index, 3) the relative diversity index, and 4) Theil’s H index. In this article, we present the command dseg, which obtains all of them. It contributes to the stock of segregation commands in Stata by 1) implementing the decomposition in a single call, 2) providing the weights and local indices used in the computation of the within term, 3) facilitating the deployment of the decomposability properties of the eight indices in

This paper presents a design methodology for the heading control system of an unmanned airship. Since the aircraft motion depends both on deterministic command signals required for tracking a desired path and on random exogenous inputs modelling the wind influence, a mixed H2/H-infinity type method have been chosen for the design of the automatic flight control. Moreover, due to the fact that the vehicle dynamics at straight and level flight is different from the model at level turning flight, a stochastic Markovian model with two states is adopted to simulate these two situations.

Resumen

A new approximate model, which consists of a variable gain and a variable time-delay, is proposed to describe the hysteresis behavior of a piezoactuator. The variable gain is assumed to be a function of the magnitude of the input command, while the time-delay is assumed to be a function of the frequency of the input command. The ranges of these two variable parameters are determined through open loop tests. According to the proposed approximate model, a Smith predictor-based robust H∞ controller is developed to achieve high-precision tracking control of a piezoactuator. Analytical simulation a

The force controller calculators the joint position corrections necessary to control the force in the desired manner. These correction signals from the force controller are output to the lower controller and added to the nominal joint position command. In this paper, we apply mixed sensitivity design of H∞ control theory to a force control system. The nominal model is discussed, and the robustness against modeling error is analyzed.

A switching amplifier with an H-bridge drive was developed for self-sensing magnetic suspension. In this amplifier, switching times are controlled by a current comparator with a small hysteresis.

When the hysteresis amplifier is used for magnetic suspension, the gap between the suspended object and the electromagnet can be estimated from the switching frequency.

The present investigation was designed to uncouple the hemodynamic physiological effects of thermoregulation from the effects of a progressively increasing central command activation during prolonged exercise. Subjects performed two 1-h bouts of leg cycling exercise with 1) no intervention and 2) continuous infusion of a dextran solution to maintain central venous pressure constant at the 10-min pressure. Volume infusion resulted in a significant reduction in the decrement in mean arterial pressure seen in the control exercise bout (6.7 ± 1.8 vs. 11.6± 1.3 mmHg, respectively). However, indexes

Resumen

During rhythmic voluntary oscillations of the foot, the excitability of the H-reflex in the Flexor Carpi Radialis (FCR) muscle of the resting prone forearm increases during the foot plantar-flexion and decreases during dorsiflexion. It is known that, when the two extremities are moved together, isodirectional (in-phase) coupling is the preferred form of movement association. Thus the above pattern of the H-reflex excitability modulation may favor the preferred coupling between the two limbs. To gain some clues about its origin, FCR H-reflex excitability was tested before and after modifying th

Resumen

This article proposes a robust haptics control algorithm for an arm exoskeleton in virtual reality application that guarantees the robustness of the force displaying performance. The developed arm exoskeleton allows the user to sense the profile of virtual objects through joints at wrist, elbow, and shoulder. Forces exerted by the user are directly measured by load cells attached to the links, which are used to determine the corresponding velocity command based on virtual impedance. Due to the imperfection of modeling and the measurement noises from load cells and encoder quantization, the for

Resumen

The toxic metal cadmium (Cd) is a major soil pollutant. Knowledge on the acute Cd-induced stress response is required to better understand the triggers and sequence of events that precede plant acclimation. Therefore, we aimed to identify the pressure points of Cd stress using a short-term exposure set-up ranging from 0 h to 24 h. Acute responses related to glutathione (GSH), hydrogen peroxide (H2O2), 1-aminocyclopropane-1-carboxylic acid (ACC), ethylene and the oxidative challenge were studied at metabolite and/or transcript level in roots and leaves of Arabidopsis thaliana either exposed or

Resumen

This paper proposes an energy management system (EMS) for battery storage systems in grid-connected microgrids. The battery charging/discharging power is determined such that the overall energy consumption cost is minimized, considering the variation in grid tariff, renewable power generation and load demand. The system is modeled as an economic load dispatch optimization problem over a 24 h horizon and solved using mixed integer linear programming (MILP). This formulation, therefore, requires knowledge of the expected renewable energy power production and load demand over the next 24 h. To ac

Mintegy 30 évvel ezelőtt, Kuvait 1990-es iraki megszállásának idején – dacára a második világháború óta megvívott csaták tapasztalatai alapján kiadott irányelveknek – az amerikai fegyveres erők különböző szintű vezetői és szakértői még mindig azon vitáztak, hogy mi is a légierő szerepe egy összhaderőnemi műveletben. A „szárazföld” berkeiben népszerű elmélet alapján – amit szerintük az 1980-as években kiadott AirLand Battle doktrína is alátámasztott – a légierő kizárólagosan a szárazföldi erők támogatására hivatott.
