Performance Measurement and Outperformance Tests
2017
This chapter explains how to evaluate the performance of a trading strategy and how to carry out a statistical test of the hypothesis that a moving average trading strategy outperforms the corresponding buy-and-hold strategy. In particular, it argues that there is no unique performance measure, reviews the most popular performance measures, and points to the limitations of these measures. The chapter then surveys the parametric methods of testing the outperformance hypothesis and the current “state of the art” non-parametric methods.
Projected fringes for the measurement of large aluminum ingots
2010
The method of projected fringes is applied to the measurement of the surface topography of aluminum ingots with surface areas of several square meters. The measurements are performed inside the casting hall of an aluminum factory. To meet the challenges encountered in such a demanding environment, it is important to keep the equipment as simple and robust as possible. Therefore a method for locating the fringe positions with sub-pixel accuracy without using for example phase shifting techniques is applied. Also the nonlinearity of the phase when using divergent illumination is discussed. The developed measuring system is tested measuring eight different aluminum ingots, and the results agre…
Fault Diagnosis for Nonlinear Hydraulic-Mechanical Drilling Pipe Handling System
2011
Leakage and increased friction are common faults in hydraulic cylinders that can have serious consequences if they are not detected at early stage. In this paper, the design of a fault detector for a nonlinear hydraulic mechanical system is presented. By considering the system in steady state, two residual signals are generated and analysed with a composite hypothesis test which accommodates for unknown parameters. The resulting detector is able to detect abrupt changes in leakage or friction given the noisy pressure and position measurements. Test rig measurements validate the properties of residuals and high fidelity simulation and experimental results demonstrate the performance and feas…
Wine competition: from between-juries consistency to sensory perception of consumers
2015
Wine is a complex product offering to consumer a multitude of choices. Considering this diversity, wine competitions provide a way of helping consumers in their choices. However, the dramatic increase of wine contests in the last fifteen years has led to an increase in the number of award-winning wines. Is a medal really a guarantee of quality or having a medal is just a matter of chance? Two studies were therefore conducted during 3 years in a French wine competition. The first study assessed the impact of the order in which the wine was assessed, and the variability between juries’ judgements and therefore the chances of winning an award. For this purpose, the same wine was placed on all …
Beyond the surface of media disruption: digital technology boosting new business logics, professional practices and entrepreneurial identities
2019
Digital disruption has recently been one of the main focal points of media management scholars. Digitalisation is regarded as the main driver of change that results in enormous managerial and organ...
Default Mode Network Efficiency Is Correlated With Deficits in Inhibition in Adolescents With Inhalant Use Disorder
2020
It is well established that alterations in cognitive function and damage to brain structures are often found in adolescents who have substance use disorder (SUD). However, deficits in executive cognitive functioning in adolescents related to the vulnerability and consumption of such substances are not well known. In this study, we use graph theoretic analysis to compare the network efficiency in the resting state for three networks---default mode network (DMN), salience network (SN) and fronto-parietal network (FPN)---between inhalant-consuming adolescents and a control group (12 to 17 years old). We analysed whether the efficiency of these functional networks was related to working memory,…
A new perspective on CMS – testing the effect of camera displacement in a realistic lane-change task

Administrative Decisions in the Era of Artificial Intelligence
2020
The rapid development of cybernetics allows the use of artificial intelligence in many areas of social and economic life. The State can also harness algorithms and machine learning for its actions. Automatic decision making should be one of the stages in the development and improvement of public administration. While it is easy to implement these solutions in the case of related decisions, decisions made under administrative discretion, general clauses or valuation standards pose a challenge. The correct transformation of paper-based public administration into automatic public administration requires a change in decision makers’ thinking, the introduction of new solutions, and building trus…
retorno a la obediencia de Juan I: la reinstauración de las décimas pontificias (1387-1393)
2020
En 1387, el papa aviñonense Clemente VII promulgó tres décimas pontificias en la Corona de Aragón que debían servir para sufragar los gastos que ocasionaban las revueltas en Cerdeña. Parte de la colecta se destinó al rey aragonés Juan I que acaba de acceder al trono tras la muerte de su padre. Se desmarcaba así de su predecesor, quien se había incautado durante nueve años de las rentas de la Cámara Apostólica. En este artículo se estudia el retorno a la obediencia de Juan I y la reinstauración progresiva del aparato fiscal y financiero pontificio en la Corona de Aragón a través de la recaudación y gestión del tributo de la décima papal. Pope Clement VII of Avignon promulgated in 1387 three …
L'arbitratge regi a la ciutat de Xátiva en el context previ a la introducció de la insaculació (1416-1427)
2017
Estudi documental que analitza com, a inicis del regnat d’Alfons el Magnànim, la sistemàtica lluita de bàndols entre el patriciat urbà a la ciutat de Xàtiva va determinar una ingerència règia cada vegada més decidida en les eleccions municipals. En aquest sentit, a partir de fonts arxivístiques reials i municipals, la recerca presenta el marc sociopolític existent en dita ciutat i quines foren les primeres petjades de l’arbitratge monàrquic desenvolupat per dit sobirà. En concret, s’exposen els procediments electorals municipals que es succeïren a Xàtiva des de 1416, el fracàs dels quals conduirà a l’atorgament –per primera vegada a la Corona d’Aragó– del privilegi d’insaculació en 1427.
