A Non-Invasive Thermal Drift Compensation Technique Applied to a Spin-Valve Magnetoresistive Current Sensor
2011
A compensation method for the sensitivity drift of a magnetoresistive (MR) Wheatstone bridge current sensor is proposed. The technique was carried out by placing a ruthenium temperature sensor and the MR sensor to be compensated inside a generalized impedance converter circuit (GIC). No internal modification of the sensor bridge arms is required so that the circuit is capable of compensating practical industrial sensors. The method is based on the temperature modulation of the current supplied to the bridge, which improves previous solutions based on constant current compensation. Experimental results are shown using a microfabricated spin-valve MR current sensor. The temperature compensati…
DC link voltage swinging and load current unbalance in fault tolerant VSI. overview and compensation strategies
2015
The topic of this paper is the discussion on the performance of a three-phase fault tolerant inverter with particular attention to the underrated aspect of current unbalances occurring due to the DC link voltage fluctuates after the inverter reconfiguration. Capacitor voltage unbalance affects not only the average output voltage of the inverter, but also its performance. In fact, the inverter performance depends on the fluctuating DC-link voltage components rather than on the average DC-link voltage. After a brief analysis of the voltage fluctuation phenomena resulting from fault tolerant configuration and their effect on load current unbalance, the Authors consider different compensating p…
Tool-Point Control for a Redundant Heave Compensated Hydraulic Manipulator
2012
Abstract In this paper, theoretical and experimental implementation of heave compensation on a redundant hydraulically actuated manipulator with 3-dof has been carried out. The redundancy is solved using the pseudo-inverse Jacobian method. Techniques for minimizing velocities and avoiding mechanical joint saturations is implemented in the null space joint motion. Model based feed-forward, combined with a PI-controller handles the velocity control of each joint. A time domain simulation model has been developed, experimentally verified, and used for controller parameter tuning. Model verification and experimental results are obtained while the manipulator is exposed to wave disturbances crea…
Relationship between employee involvement and lean manufacturing and its effect on performance in a rigid continuous process industry

Relationship between employee involvement and lean manufacturing and its effect on performance in a rigid continuous process industry DOI: 10.1080/00207543.2014.975852 Juan A. Marin-Garciaa* & Tomas Bonaviab Received: 1 Aug 2013 Accepted: 30 Sep 2014 Published online: 04 Nov 2014 This research aims to empirically test the effect of employee involvement on lean manufacturing (LM), and the effect of LM on production outcomes. Employee involvement is operationalised through four related variables: empowerment, training, contingent remuneration and communication. The effects are tested by recording management perceptions in a different industrial sector from those usually studied in previous re…
El artículo 18 del estatuto de los trabajadores italiano a la luz de las últimas reformas laborales
2015
En las siguientes líneas se realizará un somero repaso sobre las principales las modificaciones de la disciplina italiana de los despidos individuales recogida en el artículo 18 del Estatuto de los Trabajadores italiano, introducidas por las últimas reformas laborales. En ellas se constará el impacto de dichas reformas en el cuadro legislativo de referencia, viéndose reducida la posibilidad de readmisión del trabajador en el caso de despido individual improcedente. Además se harán unos apuntes críticos sobre el concepto de flexsecurity, de cual se destaca una gran inflación en el presente contexto de crisis económica. This paper examines the amendments made to the Italian regulation of indi…

Indemnización y trabajador en excedencia afectado en expediente de regulación de empleo
2021
espanolEn este trabajo se realiza un analisis de los derechos del trabajador en excedencia voluntaria que se encuentra afectado en un expediente de regulacion de empleo, concretamente, del derecho a recibir la correspondiente indemnizacion por despido colectivo o no. La doctrina judicial y jurisprudencial ha negado que el trabajador excedente incurso en un expediente de regulacion de empleo tenga derecho a la misma. No obstante, ello va unido a la posicion que se tenga sobre la naturaleza juridica de la excedencia voluntaria, aspecto debatido entre la doctrina, tanto cientifica como judicial. En este sentido, una linea doctrinal ha considerado que la excedencia voluntaria tiene un caracter …
Determinants of Chairman Compensation
2011
This study examines determinants of chairman compensation in a supervisory board setting and, specifically, the relationship between chairman and CEO compensation. Using a sample of publicly listed firms in Sweden, the study indicates that chairman compensation – despite its fixed nature – is reflective of firm performance via a positive relationship to CEO compensation. As CEO compensation is set before chairman compensation, we argue that the chairman may be inclined to conspire with the CEO in earnings management efforts at the expense of monitoring on behalf of investors. Supporting our argument, we find evidence that the gap between chairman and CEO compensation is less at firms where …
CEO Compensation and Risk-Taking: Evidence from Listed European Hotel Firms
2020
This paper examines the relationship between CEO compensation policies and financial performance in the European hotel sector. We analyze CEO cash-, equity- and total-compensation relationships with two accounting-based and two market-based financial performance proxies, including a bi-dimensional proxy formed by stock market return and risk. This bi-dimensional market-based financial performance proxy enables us to take a deep dive into the relationship between CEO compensation policies and firm risk-taking. We then analyze the nature of this relationship by decomposing market-based risk into systematic and idiosyncratic risk, using five alternative asset-pricing factorial models. Our resu…
Asymmetry of CEO Compensation and the Role of Relative and Macroeconomic Shocks in Risk Taking Incentives
2015
If managers are risk-averse and compensation schemes are not directly linked to shareholder wealth, incentives to allocate effort to manage effects of relative and macroeconomic shocks may be distorted. In this paper we develop a simple model to identify factors that determine the optimal allocation of effort to manage relative and macroeconomic shocks. We then show how serial correlation in shocks, the relative variance of shocks and the ability of managers to influence the effects of shocks on shareholder wealth determine the optimal allocation of managerial effort. Thereafter, we emphasize how CEO compensation depends on performance variables distinguishing between relative and macroecon…
