Resumen

Purpose The purpose of this paper is to examine the recursive perspective that emphasizes bureaucracy as a source of officers’ stress, explain officers’ stress as a loosely coupled effect, examine the positive effects of loose coupling and legitimize the necessity of improving context management as a stress-reduction factor.

Resumen

The loosely coupled systems (LCS) perspective emerged as a new way to understand the organizational structure from the field of Organization Studies. The purpose of this article is to present the main features of previous research studies that have addressed the perspective of loosely coupled systems. This article is based on a systematic literature review of 76 papers published during a 36-year period (1983-2019). The findings indicate that the main concepts studied around this perspective have been loose coupling, tight coupling, decoupling, degree of coupling, and coupling mechanisms, whi

Resumen

The loose coupling transformer, the core component of the rotary wireless excitation system, has a large leakage inductance due to the existence of a large gap, and the coupling coefficient cannot be effectively improved, thus limiting the improvement of the system efficiency. In order to solve this problem, firstly, the equivalent modeling and leakage inductance analysis of the rotary loosely coupled transformer are carried out, and the improved design is carried out according to the defects of common windings, and an improved shaft rotary coupler is proposed. The feasibility of this optimize

Resumen

Physiological properties of the flagellar rotary motor have been taken to indicate a tightly coupled mechanism in which each revolution is driven by a fixed number of energizing ions. Measurements that would directly test the tight-coupling hypothesis have not been made. Energizing ions flow through membrane-bound complexes formed from the proteins MotA and MotB, which are anchored to the cell wall and constitute the stator. Genetic and biochemical evidence points to a “power stroke” mechanism in which the ions interact with an aspartate residue of MotB to drive conformational changes in MotA

Resumen

An inductively coupled wireless power transfer system is proposed in this paper, which is designed to comply with the battery’s load characteristics. A loosely coupled transformer with high coupling coefficient is proposed. A heterogeneous compensation topology is proposed which is able to switch between constant current and constant voltage output mode according to the load resistance. The output characteristic curve agrees with the charging curve of the battery in a whole cycle. The proposed topology has a misalignment range of 300 mm where the coupling coefficient is 0.2.

Resumen

Inductive coupled power transfer system is based on the principle of electromagnetic induction to transfer power from the primary side to the secondary side of a loosely coupled transformer, which can transfer electricity wirelessly. The loosely coupled transformer has large leakage inductance, which reduces the power transfer efficiency. In order to reduce the leakage inductance, a capacitance is used at the primary side and secondary side of a loosely coupled transformer, which can increase the power transfer efficiency. For four different compensation structures, this paper analyses the cou

Resumen

<p>This paper presents investigations on capacitor compensation topologies with different inductive coupling links for loosely coupled inductive power transfer (IPT) system. In general, the main constraint of the loosely coupled IPT system is power losses due to the large leakage inductances. Therefore, to overcome the aforementioned problem, in this work, capacitor compensation is proposed to be used by adding an external capacitor to the system. By using this approach, the resonant inductive coupling can be achieved efficiently and hence the efficiency of the system is also increased s

Accurate system resistance may lead to an obvious error between the simulated and the real efficiency of the system. This paper proposes an optimal range of coupling coefficient for ensuring the efficiency and the sufficient output power of the WPT (wireless power transfer) system. A 3-kW prototype WPT system is manufactured and the effectiveness of the optimal range of coupling coefficient is validated.

Resumen

In living cells, molecular motors convert chemical energy into mechanical work. Its thermodynamic energy efficiency, i.e. the ratio of output mechanical work to input chemical energy, is usually high. However, using two-state models, we found the motion of molecular motors is loosely coupled to the chemical cycle. Only part of the input energy can be converted into mechanical work. Others are dissipated into environment during substeps without contributions to the unidirectional movement.

Resumen

Wireless power transfer (WPT) systems are important in many areas, such as medical, communication, transportation, and consumer electronics. The underlying WPT system is comprised of a transmitter (TX) and receiver (RX). For biomedical applications, such systems can be implemented on rigid or flexible substrates and can be implanted or wearable. The efficiency of a WPT system is based on power transfer efficiency (PTE). Many WPT system optimization techniques have been explored to achieve the highest PTE possible. These are based on either a figure-of-merit (FOM) approach, quality factor (Q-fa

This Master Thesis approaches the analysis and design of a novel solution for the “Circuito di binario (CdB”) i.e., a railway track circuit, that is used as a detection system of the trains for track management and is integrated into the signalling and safety systems on board. The presented CdB exploits an inductive loop system coupled to an S-shaped joint (replacing the previously used mechanical joints) in the audio-frequency range (from 8 to 16 kHz). The tracks, therefore, constitute a transmission route similar to a transmission line equipped with a Transmitter (Tx) and a Receiver (Rx), an

Many of the technological and social systems our society has come to depend on can be classified as complex adaptive systems (CAS). These systems are made of many individual parts that self-organize to respond and adapt to changing outside and inside influences affecting the system and its actors. These CAS can be placed on a spectrum ranging from loosely- to tightly-coupled, depending on the degree of interrelatedness and interdependence between system components.

Resumen

In complex systems, it has been observed that the parts within the system are "loosely coupled". Loose coupling means that the parts of the system interact in some way, and as long as this interaction is maintained the parts can evolve independently. Detrimental evolutionary changes within one part of the system do not negatively affect other parts. Overall system functionality is maintained, leading to faster evolution. In swarm robotic systems there are multiple robots working together to achieve a shared goal. However it is not always obvious how to program the actions of the robots such th

Eigenfrequencies of the 1st torsion mode and the 4th flap mode of the reduced 3-D blade model exhibit a stronger coupling than the 1-D analysis prediction.

Resumen

In this work, comparisons between simulations & measurements in flight are proposed for different low-speed flight conditions out of ground effect on an Airbus Helicopters H175 PT1 rotorcraft equipped with a 5-bladed Spheriflex® rotor. Numerical results have been obtained by full-helicopter unsteady simulations relying on a single-rotor loose coupling approach between the Computational Structure Dynamics& Computational Fluid Dynamics parts, assuming blade elasticity and six degrees-of-freedom trim. One flight condition is tackled with both rigid-blade and elastic-blade modelling so as
