TURNING DATA INTO VALUABLE INSIGHTS: THE CASE STUDY IN AVIATION SECTOR COMPANY
2017
Since the early 2000s, there is increasing pressure on Human Resource Departments to show their impact on organizational performance. This pressure is related to the shift from industrial based economies to knowledge based economies and positioning people as potential sources of competitive advantage, and to the rise of Evidence-Based Management (EBM), which requires making decisions based on data and analysis. New technologies have enabled HR departments to start a transition from HR metrics to HR Analytics, thus transforming from the traditional administrative HR function to a more strategic HR function that can express qualitative matters and its impact on organizational performance with…
Contributions Regarding the Application of the Six Sigma Method in Tourism as a Quality Engineering Method
2015
The problem of quality and customer orientation are the most important leverage in obtaining success. Over the time, the influence of human resources in terms of training, controlling and shaping client expectations has gained significant meanings. Research in this field has led to the formulation of the hypotheses according to which human resources can represent a vital element in obtaining a competitive advantage. In line with the importance of the topic addressed, the main objective of these scientific approach is to identify the current problems related to the quality of Romanian tourism services and to propose a improvement program using the six sigma method. The paper provides an exce…
Remote programming of network robots within the UJI Industrial Robotics Telelaboratory: FPGA vision and SNRP network protocol
2009
This paper presents the UJI Industrial Robotics Telelaboratory, which lets Ph.D. and Master’s degree students perform robotics and computer vision tele-experiments. By using this system, students are able to program experiments remotely via the Web, in order to combine the use of a field-programmable gate array (FPGA) to provide real-time vision processing, a conveyor belt, and a Motoman industrial manipulator. This paper introduces the novel SNRP protocol (i.e., Simple Network Robot Protocol), which permits the integration of network robots and sensors within an e-learning platform in a simple and reliable manner. As long as the students are able to interact remotely with a real robotic sc…
Planning Rehabilitation Actions on Water Distribution Networks in Condition of Data Scarcity
2011
The paper shows a viable approach to the selection of water networks rehabilitation actions, in condition of data scarcity and uncertainty, based on the use of four concise performance literature indices, allowing the analysis and identification of efficient, reliable and robust rehabilitation alternatives, even if assessed on the basis of a relatively small amount of data. A promising statistical sampling method of water consumptions is also described, that may be fruitfully employed within the proposed approach for drafting water balances at network district scale in order to quantify the extent of leakages. The illustrated case study shows that the selected indices are capable to describ…
Photovoltaic plant array reconfiguration: Design of a new device
2014
An efficient strategy to improve unequally irradiated PV plants performances is based on the reconfiguration of the connections between the modules. In this paper, an algorithm, for this purpose conceived, is presented. Moreover, the design, realization and finally also the set up of a new reconfiguration system device is fully shown and discussed. The algorithm conceived simulates several possible series-parallel connections under varying irradiation conditions, and determines the optimal modules connection in order to get the maximum output power. In this way, the reconfiguration system may set up the reconfiguration strategy. The reconfiguration system prototype set up, basically consist…
Long term energy efficiency study on different wall envelopes in Latvian climate conditions
2017
Abstract Five test stands have been built in Riga, Latvia equipped with sensors (temperature, solar radiation, humidity, etc.) to measure energy efficiency and thermal comfort conditions. Roof and floor constructions are made the same. For the walls building envelopes differ and typical materials used in Latvia (aerated concrete, ceramic building blocks, wooden log and plywood frame with rock wool insulation) are compared. Only rock wool is used for insulation to provide moisture transport through the construction. For study to be comparative thermal transmittance of all five test stands have been calculated equal (U=0.15…0.16 W/(m 2 ∙K)). The aim of research is to compare the integral calc…
Optimization model predictions for postural coordination modes
2003
International audience; This paper examines the ability of the dynamic optimization model to predict changes between in-phase and anti-phase postural modes of coordination and to evaluate influence of two particular environmental and intentional constraints on postural strategy. The task studied was based on an experimental paradigm that consisted in tracking a target motion with the head. An original optimal procedure was developed for cyclic problems to calculate hip and ankle angular trajectories during postural sway with a minimum torque change criterion. Optimization results give a good description of the sudden bifurcation phase between in-phase and anti-phase postural coordination mo…
Identification of Defensive Performance Factors in the 2010 FIFA World Cup South Africa
2016
The aim of this study was to determine the efficacy of defensive play in elite football, to identify variables associated with the direct recovery of ball possession, and to propose a model for predicting the success of defensive transitions. We analyzed 804 transitions in the final stages of the Fedération Internationale Football Association (FIFA) World Cup 2010, and investigated the following variables using univariate, bivariate, and multivariate analyses: duration of defensive transition, possession loss zone, position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, time of the match, position of defense, zone in which t…
Performance Measurement Framework with Formal Indicator Definitions
2011
Definition of appropriate measures of organization’s performance should be conducted in a systematic way. In this paper the performance measurement and indicators are discussed not only from the side of management models, but also from the point of view of measurement theories to find out appropriate definitions. In our work we propose a formal specification of indicators. The principles of indicator reformulation from free form indicators to formal requirements are formulated and applied in several examples from performance measures database. The formally defined indicators could be used in the proposed performance measurement framework that covers five-step indicator lifecycle.
<title>Evolution of optical links toward full-optical transparency</title>
2003
In this paper we review issues of evolution of optical networks towards their full optical transparency and present sequence of eliminating non-transparent elements out of optical links (networks). Architectures of optical commutators with electrical and optical cores have been presented, as well as a structure of OMO (optical-millimeter wave-optical) switching fabric. An example of pure al-optical switch, made by Luxcore, utilizing dispersion compensating elements, wavelength converters and and variable optical attenuators (VOA) operating entirely in optical domain without optical-electrical-optical (OEO) conversions, was quoted. We brought up an issue of all-optical 3R signal regeneration…
