Legal interpretation of the Directive 92/50/EEC in differing contexts

The Council Directive 92/50/EEC of 18 June 1992 relating to the coordination of procedures for the award of public service contracts establishes shared rules and procedures for the award of public service contracts within the internal market. The directive defines the public service contract award criteria, contracting authorities are bound to apply. Purpose of this study is to demonstrate how leg

Häng och släng

What if you could accomplish order by being lazy? The project is about the balance between order and disorder. Without any extra thought, sorting clothes to create a calm environment for both eye and mind. Häng & Släng is a clothing rack that yields order in the disorder of half-used clothes (not clean but not yet ready for laundry), without demanding effort. The sense of order is achieved by

Early Bird - For a better morning

This project have been about creating an object that helps the user to fall asleep and wake up comfortably. Today a lot of people use their smart phones as their standard alarm clock. It is simple, practical and doesn’t take up much space in the bedroom. However the smart phone is not sufficient to create a pleasant wake-up experience. To achieve a pleasant morning a lot of people instead use Wake

Design and Implementation of a 2-Channel High Precision and High Speed Digitizing system

Recently, new spectroscopic techniques have been developed such as photocurrent detected two-dimensional spectroscopy [1], which measure the response from a sample that is excited by a high intensity laser pulses. The responses are linear and nonlinear signals that have very different amplitudes; the linear signal can be from 103 to 105 times larger than the nonlinear signal. These two signals hav

Understanding The Drone Campaign in FATA, Pakistan : An investigation of Pre-emptive and Preventive warfare

The purpose of this thesis was to investigate the difference between Pre-emptive and the Preventive use of force in a low-intensity conflict to which the drone campaign is a critical part of. Northern Pakistan has borne the brunt of the U.S. led drone campaign, and the Obama administration has exponentially increased the number of strikes that continues to target armed non-state entities in the tr

A Space-Time Study of the Electron-Electron Interaction in High-TC Parent Compound La2CuO4: In Search of an Attractive Effective Interaction

The superconductivity under doping in the famous cuprate compounds is believed to originate in the CuO2 planes. The mediator of pairing is generally accepted to be induced from electronic degrees of freedom. While many mechanisms, such as spin fluctuations, have been proposed throughout the years, little research has been carried out on the role of the retarded attraction due to electronic overscr

Ventilation efficiency measurements - a comparison between three supply air methods

Trötta ögon, huvudvärk, för kallt eller för varmt och allmänt lägre prestationsförmåga. Så kan det se ut på ett kontor med dålig ventilation och detta minskar förtjänsten för företaget samtidigt som det för de anställda upplevs påfrestande. Med ett väl dimensionerat, och rätt valt tilluftssystem blir inomhusklimatet avsevärt bättre och de anställda har de bästa förutsättningarna att med glädje preThis study compares the two traditional ventilation methods ; mixed ventilation and displacement ventilation, with a new type of dif fuser which attempts to solve the problem with blockage of the diffuser for the displacement ventilation. This new diffuser called Airshower is a product developed by Airson engineering AB whom is also the company where all simulations and tests for this study were

Design and Implementation of Customer Support Awareness Dashboard

Customer relation is an important factor in service minded sectors, and providing a flawless support to compliment that service can be an important factor while having customers. This puts support personnel in a crucial role to handle problems that the customer requests, but also see to it that the problems never happen. Telavox, a telecommunications company, supplies various communication service

A Simulation Study comparing MCMC, QML and GMM Estimation of the Stochastic Volatility Model

The stochastic volatility (SV) model is an alternative to GARCH models to model time varying volatility. In this thesis the basic stochastic volatility model and three different estimation methods are described---namely, Bayesian Markov chain Monte Carlo (MCMC) methods, quasi maximum-likelihood (QML) and generalized method of moments (GMM). To compare these estimation methods a large scale simul

The Effect of Food Shortage on Marital Fertility in Malawi 1987-2009

This thesis seeks to examine the effect of food shortages on marital fertility in Malawi for the period of 1987-2009. Malawi provides an interesting case for studying this relationship, since the country has experienced many instances of food shortages in the studied period. The study was done by using the 2004 and 2010 Demographic and Health Survey for Malawi to utilise the retrospective data ava

Commercialization of used vehicle batteries - Battery 2nd life business opportunities for the heavy duty vehicle sector

The purpose of this thesis was to determine how a heavy duty vehicle manufacturer can create an economical viable business model for used batteries from electric buses and trucks. Heavy duty vehicles are responsible for 30% of on-road CO2 emissions in the European Union, but could be decreased if this sector would be electrified. One major barrier for this transition is the large cost for the batt

A challenge for development or challenging development : ecosystem-based adaptation to climate change in the Hindu Kush Himalayas

Mountains provide a variety of ecosystem services, such as drinking water, which sustains not only mountain communities but also people living further downstream. While climate change threatens most ecosystems, its negative impacts are up to three times greater in high altitudes. As well as changing the water cycle this further accelerates climate change. Although they contribute comparably little

Response of Buildings Exposed to Blast Load - Method Evaluation

Due to accidental external explosions ,which is not handle in the Eurocodes, are structural designers looking for other ways to design loads for external loads due to explosions. This combined with lighter building structures is a reason to address the issues of analysing the dynamic behavior of buildings subjected to air blasts from these extreme situations. The structural designers analyze the

Membrane evaluation and thermal modelling of the vanadium redox flow battery

Framtidens energilagring banar väg åt förnyelsebar elenergi Andelen förnyelsebar elenergi på marknaden ökar ständigt. En negativ aspekt med dessa källor är att vi inte kan kontrollera när energin skall vara tillgänglig – vindkraften behöver vind och solkraften behöver strålande sol. För att överkomma dessa motsättningar och göra energin mer tillförlitlig behöver vind och solenergi kompletteras meIn this study, different membranes were tested for their use in a vanadium redox flow battery (VRB). The membranes were first tested under charge-discharge operation of the VRB over four charge-discharge cycles at different current densities (20 mAcm-2, 40 mA cm-2 and 60 mAcm-2) and the corresponding cell performance was evaluated in terms of total energy efficiency (EE), coulombic efficiency (CE)

Sowing seeds of trust : social learning in farmer family learning groups

Agricultural systems, specifically in the global South, and the people living of them, are more than others, exposed to changes in the environment around them. Smallholder farmers (that work in agroecological systems), with a low standard of living, are the most vulnerable to short-term shocks and long-term stresses. There have been attempts by development agencies, researchers and local governmen

Bulging of Insulating Glass Units - Numerical and Experimental Analysis

Insulating glass unit (IGU) is separated double or triple glass panes with closed cavities in between, usually filled with argon to reduce the heat transfer. When a construction like this is exposed to temperature variations the volume of the gas will change and pressure changes will occur. The glass panes will bulge which will give displacements and stresses in the glass panes. For large dimensio

Development of Methodology for Generating Response Spectra for Decoupled Smallbore Piping

In nuclear piping engineering, the response spectrum method of analysis is widely used to analyze piping systems. The matter of combining modal responses is of great interest. Complications may occur with the response spectrum method for large systems. Examples are convergence issues and something called twin-mode effects that may overestimate the effects on the system.
