Abstract:

The present thesis addresses several topics of thermal-hydraulics applied to the heat transfer in the nuclear field, both in normal operating and accidental conditions. The problem is to demonstrate that innovative heat exchanger geometries and safety systems are able to effectively remove thermal power from a primary system of a nuclear reactor. Normal operating condition was addressed by looking at several heat exchanger and steam generator geometries for heat removal in advanced nuclear reactors, such as Small Modular Reactors and generation IV reactors. Helical coil, microchannel and bayon

Abstract:

This research contributes to the existing body of knowledge relating to crash compatibility (the minimisation of injury risk faced by all participants involved in a collision in traffic). The research focuses on the topic of structural interaction in collisions involving passenger vehicles, a phenomenon describing the efficiency of energy dissipation within existing deformation-zones of a passenger vehicle during a collision. A new definition for structural interaction was developed and several metrics to evaluate structural interaction and compatibility in car-to-car collisions

Abstract:

Adverse drug reactions (ADRs) present heavy burdens for the public health care system, and current pharmacovigilance activities are challenged by the under-reporting of ADRs in spontaneous reporting systems and a lack of incentive for industry to conduct rigorous post-approval research. As part of a new lifecycle approach to drug regulation, Health Canada recently announced plans to develop a new health product vigilance framework that will allocate drug safety resources using prioritization schemes focused on higher risk. These plans include the development of official policy requirements f

Abstract:

In this thesis project a concrete sandwich wall element of 250 mm insulation of Kooltherm has been resulted to have U-values and ψ-values closer to the passive housing recommendations. However, by using 180 mm thick insulation, no significant difference in the annual energy consumption is observed. Using a metal sheet in the window connection and small concrete brackets, low thermal bridge values are achieved. Low thermal bridge coefficient values were also observed with thick insulation in the foundation and the roof structure, although, it is impossible to achieve values below 0,01 W/mK in t

A dissipative passive haptic display is one that may only remove energy from the system using actuators such as brakes and dampers, thus ensuring the safety of the human operator. These devices may be used to implement virtual constraints such as desired paths and obstacles.

Most of these manipulators are modified industrial robots. However, the use of high-powered mechanisms in the operating theatre could compromise safety of the patient, surgeon, and operating room staff. As a solution to the safety problem, the use

The nuclear power sector has a history of challenges with its relative competitiveness against other forms of electricity generation. The availability of low cost low natural gas, the Fukushima accident, and the cancellation of the AP1000 V.C. Summer project has caused a considerable role in ending the short lived “Nuclear Renaissance.” Historically, the nuclear industry has focused on direct cost reduction through construction, increasing installed capacity, and improving efficiencies to capacity factors in the 1990s and 2000s as ways to maintain competitiveness against other forms of energy

The need for sustainability leads to the construction of more airtight buildings to increase the energy efficiency, according to the Directive 2010/31/EU. New kinds of building like passive houses are thus developing to diminish the environmental impact. So there can be risks related to the pressure increase due to the thermal expansion of fumes in such structures in case of fire. The aim of this report is thus to examine the influence of building airtightness on fire pressure and its consequences about the safety of occupants and firefighters.

Abstract:

En aquesta tesi doctoral es proposa utilitzar la tècnica LIDAR (Light Detection And Ranging) per estudiar la deriva de pesticides. A diferència dels col·lectors in situ, aquesta tècnica permet mesurar els aerosols de forma remota, amb elevada resolució temporal i en distància. Els objectius d’aquesta tesi són (1) dissenyar un sistema lidar específic per la mesura de la deriva i (2) avaluar la capacitat d’aquesta tècnica per quantificar la concentració en els núvols de pesticides. Per la consecució de l’objectiu (1) s’ha elaborat una metodologia de disseny, validada mitjançant la construc

Abstract:

Motor vehicles passing cyclists too closely is both unsafe and feels unsafe. The aim of this research was to increase understanding of the factors that influence passing distances and perceived risk, using the Comfort Zone Model. The Comfort Zone Model predicted the factors influencing the passing distances chosen by drivers which include traffic, road, and cyclist attributes. Passing distances and other factors such as motor vehicle speed, vehicle size and car parking then predict the perceived risk of passes for both cyclists and drivers.

Abstract:

It is illegal to pass a stopped school bus when the vehicleâ s stop-arm is extended and the red lights are flashing. Public opinion on this issue is very clear. A random phone survey of the public conducted by the National Highway Traffic Safety Administration (NHTSA) reported that more than 90 percent of respondents rated â passing a school bus that has its red lights flashing and the stop arm in full viewâ as a somewhat or extremely dangerous driving behavior (Boyle, Dienstfrey, and Sothoron, 1998). Despite this public opinion, there is evidence that the number of vehicles that illega

Abstract:

Loss of connectivity in riverine systems due to construction of hydropower dams has resulted in a worldwide decline of anadromous salmonid species such as Atlantic salmon (Salmo salar L.) and sea trout (Salmo trutta L.). The future of these species depend on the presence of available spawning habitat in freshwater river systems. Modern research and mitigation efforts mainly focus on ensuring a successful upstream passage past dams e.g. fish ladders. Atlantic salmon and sea trout are iteroparous, and are thus able to spawn repeatedly during their lifetime. Individuals surviving upstream migrati

Abstract:

Parmi les nombreuses applications des sources laser, certaines nécessitent une propagation du faisceau dans l'atmosphère sur plusieurs kilomètres : télémétrie, désignation, ou encore imagerie active. Pour éviter tout risque oculaire tout en proposant de plus grandes portées, ces applications doivent faire appel à des sources laser émettant une longueur d'onde dans la gamme à sécurité oculaire autour d'un minimum local d'absorption de l'atmosphère (1550-1650 nm). De telles sources existent déjà commercialement, mais ne répondent pas aux exigences militaires de compacité, de consommation électri

Abstract:

Current design methods in transportation engineering do not simultaneously address the levels of risk and service associated with the design and use of various highway geometric elements. Passing sight distance (PSD) is an example of a geometric element designed with no risk measures. PSD is provided to ensure the safety of passing maneuvers on two-lane roads. Many variables decide the minimum length required for a safe passing maneuver. These are random variables and represent a wide range of human and vehicle characteristics. Also, current PSD design practices replace these random variables

Abstract:

In this master thesis a small modular sodium-cooled metal-fuelled pool-type fast reactor design, called SPARC - Safe and Passive with Autonomous Reactivity control, has been designed. The long term reactivity changes in the SPARC are managed by implementation of the the Autonomous Reactivity Control (ARC) system, which is the novelty of the design. The overall design is mainly based on the Integral Fast Reactor project (IFR), which experimentally demonstrated the passive safety characteristics of a metal fuelled, sodium-cooled, pool-type reactor system. Whilst mimicking the passive safety feat

Abstract:

An einbahnige Außerortsstraßen (Landstraßen) werden sehr hohe Anforderungen gestellt. Einerseits sollen sie eine hohe Verkehrssicherheit aufweisen und andererseits gemäß ihrer Verkehrsbedeutung eine angemessene Verkehrsqualität und Leistungsfähigkeit bereitstellen. Im Landstraßennetz liegt die Erfüllung dieser Anforderungen jedoch vielerorts deutlich unter den Erwartungen. Unfälle auf Landstraßen sind im Vergleich zu Autobahnen oder Innerortsstraßen durch eine besonders hohe Schwere gekennzeichnet. Sehr hohe und oft an den Streckenverlauf nicht hinreichend angepasste Geschwindigkeiten, Fehlei
