Abstract:

Intrinsically safe (IS) active power supplies subjected to certain transient load conditions can deliver power to a circuit at significantly higher levels than indicated on their nameplate ratings. During a transient load such as an intermittent short-circuit, energy is transferred from the power supply to the short-circuit and an electrical arc may form when the short-circuit is applied or removed. This poses a spark ignition risk as energy is transferred from the arc to the surrounding atmosphere. Currently various International and Australian Standards define the performance requirements

Abstract:

A field study investigated the relevancy of certain theories in applied psychology for increasing vehicle safety belt use by children. Five different intervention activities applied either extrinsic rewards, or focused on the development of intrinsic motivation (e.g., personal commitment, awareness, active participation). The subjects were 138 children, aged five to eleven years, who attended five 30-min safety belt intervention activities as part of a summer recreation program conducted at three elementary schools. Safety belt use by children and their parents was directly observed and coded

Abstract:

La produzione di energia a partire da biomassa rappresenta un'importante alternativa all’utilizzo di combustibili fossili, al fine di ridurne il consumo globale e di limitare le emissioni di gas serra. In questo contesto, il biodiesel è una delle soluzioni più promettenti tra i biocarburanti esistenti per la sua natura rinnovabile, la sua bassa tossicità e il suo basso impatto ambientale rispetto al diesel ottenuto da petrolio. Dal punto di vista chimico, il biodiesel è un estere alchilico di acidi grassi a lunga catena (principalmente FAME) sintetizzato a partire da varie materie prime lipidi

L’histoire des événements accidentels dans les industries chimiques montre que leurs conséquences sont souvent graves sur les plans humain, environnemental et économique. Cette thèse vise à proposer une approche de détection et de diagnostic des défauts dans les procédés chimiques afin de prévenir ces événements accidentels. La démarche commence par une étude préalable qui sert à identifier les causes majeures responsables des événements industriels chimiques en se basant sur le retour d’expérience (REX).

The main body of this thesis consists of six appended papers. In the first two, different cooperative surveillance problems are considered. The second two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively.In Papers A and B, a combinatorial optimization based framework to cooperative surveillance missions using multiple Unmanned Ground Vehicles (UGVs) is proposed. In particular, Paper A considers the the Minimum Time UGV Surveillance Problem (MTUSP) while Paper B treats the C

Abstract:

Spontaneous heating property of coal is a matter of prime concern in mining industry. Spontaneous combustion of coal has caused many mine fires leading to huge loss of coal and also loss of many human lives. Storage and transportation of coal requires knowledge about the spontaneous heating liability of coal, as it starts degrading on coming in contact with air. Numerous studies and research work has been done to understand the mechanism of spontaneous heating and its relation with coal’s intrinsic properties. The present study presents the correlation of spontaneous heating susceptibility of

During the development of this concept there will be presented the most important concepts of this strategy. Throughout this study, it will also be analysed the market as well as investors’ tendencies and demonstrated that value investing is not based on tendencies and predictions. It will show that Price and Value of securities are the most important variables in taking

The moderating role of psychological safety is explored as well. Research findings based on a sample collected from 407 respondents in 20 IT companies indicate that intrinsic motivation and creativity indeed play mediating roles in between role conflict and ambiguity and job performance.
