Smart grids have been proposed as a way to increase grid robustness and reduce consumption peaks and at the same time decrease electricity costs for the end users. This thesis aims to develop generic models for smart grids focusing on smart houses which are used to test if it is possible to reduce consumption peaks, decrease electricity cost and at the same time increase grid stability. Models hav

Electrical machines in electrical vehicles are sometimes put under a lot of stress when for example climbing an uphill road. In order for the machine to cope with the heat generation that comes of running extended periods of time near or at peak power one needs a highly developed cooling system. At the division of Industrial Electrical Engineering and Automation (IEA), located at Lunds Tekniska Hö

Abstract Future climate change scenarios project a water temperature increase of 2 to 5 ˚C for the upcoming 100 years. Simultaneously, north temperate zones will face precipitation changes that will ultimately enhance humic content and water colour in freshwater systems. I hypothesised that increased temperature and water colour would benefit the grazing activity of mixotrophs, and the dominance

Som ett steg i utvecklingen av nästa generations hjullastare görs studier av olika delsystem för att se var energiförbrukningen ligger. Denna masteruppsats har som mål att ta reda på energiförbrukningen för fyra länkage med olika konstruktion. Den kommer även att undersöka hur energiförbrukningen förändras när en elektro-hydraulisk kompensering introduceras för att hålla lasten parallell samt vad As a stage in the development of the next generation of wheel loaders, all systems are evaluated in order to minimize the energy consumption. This master thesis aims to investigate the energy consumption for four linkages with different design. It will also investigate how the energy consumption changes when an electro-hydraulic compensation is added in order to keep the load parallel and what the

To be able to change gears in a transmission it is necessary to remove the torque when disengaging and engaging gears in order not to damage the teeth of the cogs. If the driving torque from the engine to the wheels is interrupted for a longer period of time it can be perceived as very uncomfortable for both the driver and passengers in the vehicle. A gear change can be divided into three main sta

Quantum entanglement between electrons in nanostructures is a key concept of quantum information still waiting to be experimentally demonstrated. In this master's thesis we present and analyze the full counting statistics of the charge transfer of a sextuple quantum dot system which works as both entangler and detector of spatially separated electrons. Under certain resonance conditions the sy

Seminariedatum: 2014-06-04 Ämne/kurs: Examensarbete i Strategic Management på kandidatnivå, 15 HP. Författare: Siri Albrecht, Adam Svingstedt och Hugo Wennberg Handledare: Magnus Nilsson Nyckelord: E-handel, Returhantering, Returns Management (RM), Avoidance, Gatekeeping, Konkurrensstrategi, Supply Chain Management (SCM) Syfte: Att undersöka i vilken utsträckning gatekeeping och avoidance integ

With the diminishing reserves of oil and the growing public concern for environmental issues, the end of gasoline powered vehicles is getting closer each year. To prevent this from causing the personal and comfortable way of transportation mankind has gotten used to, to die with them, an alternative without the downsides of the gasoline engine must be developed. The environmentally friendly electr

The production of knowledge and claims of objectivity in Irish revolutionary historical narratives are discursively gendered processes which maintain a power-differentiation between the sexes through the assignment of a hierarchy of significance to the participation of men and women in the Irish struggles for independence. The partial visibility of women in such historical accounts is discursively

Syftet med denna studie är att analysera populära svenska arbetsgivares syn på fenomenet lärande i arbetslivet. Respondenterna för studien har varit företag på Universums lista över Sveriges mest populära arbetsgivare. Studien har tagit avstamp i en fenomenografisk metodansats med semi strukturerade intervjuer för datainsamling som har riktats mot anställda inom företagen som har insikt i företage

De finns många olika faktorer som påverkar miljöns tillstånd, varav två av dessa är produktion och konsumtion av livsmedel. Maten vi äter och slänger har en mycket negativ effekt på miljön, exempelvis genom utsläpp av växthusgaser och användning av kemiska bekämpningsmedel. Att arbeta med att minska klimatpåverkan från livsmedel är därför viktigt för att vi ska kunna förbättra miljöns tillstånd oc

Syfte: Syftet med denna uppsats har varit att undersöka om marknaden är effektiv före, efter och sammantaget vid produktannonseringar. Uppsatsen inkluderar nio bolags produktannonseringar och dessa har skett mellan 2007-2014. Metod: För att undersöka om det fanns en abnorm avkastning före, efter och sammantaget vid produktannonseringar har nio bolag studerats. Dessa har alla annonserat konsumenti

Abstract: This thesis combined the individual level longitudinal data, from the 2011 Ethiopian demographic and health survey, with annual GDP and price indicators, to examine the response of marital fertility to short term macroeconomic stress that Ethiopians has been facing in the last forty years. A two-level discrete time random effect models were employed to estimate the risk of next birth. Ru

The importance of body image is increasing in China. Academic research and news media point to the rising desire for an ideal appearance, especially among young people in the country, in order to gain an advantage in society. This thesis was conducted to examine if university students at a high-ranking university in China were influenced by commercial ideals in the media to the same extent as youn

The thesis analyses the EU arms embargo on China and the reasons why this sanction is in place since 1989. The arms embargo case characterizes the EU-China foreign relations also in general and in order to understand the real background behind this case, historical institutionalist perspective and path dependence theory is used. The thesis acknowledges two different paradigms – normative power and

Video on Demand (VoD) is a service that delivers video seamlessly to the consumer on demand. This thesis examines the consumers’ opinion on the different VoD services that exists on the Swedish market. To conduct our research we collected quantitative data by using a survey and then conducted a qualitative analysis. As a theoretical framework we used our own modified version of The DeLone and
