Résumé :

This paper estimates the effects of imports on employment, wages, and the wage share in Austria for the period of 1990-2005 using panel data of manufacturing industry. Imports are disaggregated according to their origin and as final vs. intermediate imports. There is evidence of significant negative effects of imports on employment, wages and the wage share. Particularly workers in high skilled sectors experience negative effects. Offshoring to both Eastern Europe and the developed countries have a negative impact on employment, whereas offshoring to the East has a positive effect on wages, in

Résumé :

The major limitation of many studies on declining industries is the presumption that industrial decline is associated with the final stage of the industry life cycle. These studies often define the sample of their study as those firms where their dominant products are subjected to technological obsolescence and are experiencing a persistent decline in the demand of their products. Conversely, the current study identified factors that the cause of the shrinking in demand of the UK industries was not generally obsolete technology. The decline of UK industries was partly due to severe low cost im

Résumé :

The growth of renewable energy, especially PV system has been accelerated in the past decades. With this growth, several problems have been identified that can interfere with the power quality on the distribution network. These problems include; voltage rise, voltage unbalance, voltage sag/swell, flickering, and harmonic issue. IEEE 13 bus distribution network has been chosen to be the base of this research due to its flexibility and it has been modeled in DigSILENT Power Factory.

We use the three-dimensional finite element code DYNA3D to analyze two problems: (a) the normal impact of a cylindrical monolithic or composite rod against a smooth flat rigid target, (commonly known as the Taylor impact test), and (b) the penetration of composite and monolithic steel cylindrical rods into reinforced concrete targets. The composite rod is made of either a steel or copper shell enclosing a ceramic. The ceramic and the steel are assumed to fail at a critical value of the effective plastic strain, whereas no failure is considered in the copper. The thermoviscoplastic response

We study axisymmetric deformations of depleted uranium (DU) and tungsten heavy alloy (WHA) rods impacting at normal incidence both a rigid, planar target and a thick, deformable steel target. Each deformable material is modeled as elastic thermoviscoplastic; the flow stress increases with an increase in the effective plastic strain and effective plastic strain-rate but decreases with a rise in the temperature. An objective of this work is to ascertain when and where a shear band, defined as a narrow region of rapid, intense plastic deformation, forms in each material subject to impact loading.

In recent impact and penetration mechanical tests, steel projectiles (AISI4340) were impacted into targets like concrete with striking velocities (1200 m/s to 1500 m/s). Results indicated a material removal from the nose of the projectile, phase changes of the projectile materials, a reduction in the length of the projectile, and a blunting of the nose shape. These observations cannot be explained by current theories and numerical integration code that are used to study impact and penetration mechanics.

Résumé :

Since the 2008 energy crisis, the national utility has been under stress to meet the country's electrical demand. Moreover, the costs of building new conventional power stations and the operation and maintenance costs of existing ones are taking a toll on the economy. The utility has hence resorted to hiking electricity tariffs. This combination of rising electricity prices and decreasing costs of photovoltaic (PV) technology have hence led a number of households to cover part of their electricity demand by self-produced captive solar PV technology.

Résumé :

The growing popularity of photovoltaic (PV) generation systems leads to an increase in the number of residential and commercial grid-tied PV systems that interconnect to the distribution circuit. This affects the characteristics of the distribution circuit; for example, the assumption that the voltage profile of a radial line decreases down-stream becomes invalid because of the addition of the PV system on the line. This poses new challenges when setting the parameters of voltage regulating devices. Add to that the fact that PV systems are intermittent, especially on cloudy days, which make th

The sandbags were stacked in a pyramidal stacking configuration according to military specifications in order to simulate a section of a sandbag barrier or redoubt as would be seen on the battlefield.

Wind power generation has gained a large share in the renewable energy market over the past few years. This study investigates the impact of large scale penetration of permanent magnet synchronous generator (PMSG) based wind turbines on power quality of the grid. PMSGs are attractive due to the absence of a gearbox in the drive-train, which results in lower maintenance costs and higher reliability. Moreover, the advancements in power electronics have facilitated PMSGs to generate optimal power at varying wind speed conditions. This is achieved through the use of maximum power point tracking al

The rate at which the integration of distributed generation (DG) penetrates the public power supply has started to put various demands on the distribution system, since they are directly connected to the network.

The increasing demands placed by grid services on the DGs, especially the PV types have a serious impact on the distribution system.

New European energy policies have set a goal of a high share of renewable energy in electricity markets. In the presence of high levels of renewable generation, and especially wind, there is more uncertainty in the supply. It is natural, that volatility in energy production induces the volatility in energy prices. This can create incentives for the generators to exercise market power by traditional means: withholding the output by conventional generators, bidding not the true marginal costs, or using locational market power.

Résumé :

This degree project presents a study case in Eskilstuna-Sweden, regarding the effect of the photovoltaic (PV) systems with battery energy storage system (BESS) on a power distribution transformer, and how they could change the transformer lifespan. For that, an extensive literature review has been conducted, and two MATLAB models were used to simulate the system. One model simulates the PV generation profile, with the option of including battery in the system, and the other one simulates the transformer loss of life (LOL) based on the thermal characteristics. Simulations were using hourly time

Résumé :

The Southern Appalachian hardwood forests contain a wide diversity of flora and fauna. Understanding processes that affect nutrient availability in these forests is essential for sound forest management. Three interconnected research projects regarding soil resource heterogeneity were designed to increase our understanding of this ecosystem. The objective of these projects were as follows: 1) to examine and quantify the role of decaying stumps in regards to total carbon (C) and nitrogen (N) pools and fine-root dynamics, 2) compare and contrast the use of ground-penetrating radar (GPR) vs. a

Résumé :

Dans le cadre de la simulation numérique portant sur la prédiction de phénomènes complexes, la modélisation de la pénétration d’un corps à travers un solide reste un challenge. Ceci est d’autant plus vrai si le corps impacté comporte une épaisseur importante devant les dimensions du projectile. Notamment, dans le contexte de la biomécanique des chocs, l’investigation des traumatismes suite à une blessure par balle, par un moyen numérique, nécessite la modélisation d’une zone pouvant être de plusieurs dizaines de fois supérieure aux dimensions du projectile sur un temps extrêmement court (de l’

Résumé :

La fabrication additive est en pleine expansion et suscite un intérêt grandissant pour l'industrie, la recherche scientifique et le grand public. Les procédés additifs ont permis des ouvertures pour fabriquer des structures à géométrie complexe par rapport aux fabrications classiques. En revanche, le comportement mécanique des fabrications additives en réponse aux chargements est peu exploré. En particulier la caractérisation mécanique de ces fabrications reste un challenge et se limite souvent à des champs d'investigations pseudo-statiques par des moyens de tests mécaniques classiques tels qu
