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
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
This is an investigation where I describe and circle in the media person Yahya Hassan, the poet slash the rapper slash the politician, and his public persona in interviews, TV programs, books, song lyrics, Facebook, etc. The purpose is with use of Jon Helt Haarder´s concepts aesthetics of the threshold, feed-back loop and haunting, as well as Poul Behrendt´s concept the double contract, analyze Ha
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
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
This 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
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
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
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
Sammanfattningsvis består arbetets problemställning av: • Presterar kv Betan enligt den energiprestanda som huset är projekterat för och är kv Betan ett bra projekt att använda som referens? • Hur fungerar erfarenhetsåterföring inom Företaget idag och hur kan hantering av information förbättras? Vilka verktyg behövs för att förenkla Företagets sätt att arbeta med projekt som kräver mätning och ko
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
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
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
In 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)
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
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
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. This master thesis investi
The actual concept of food security focuses on four food security dimensions: food availability, food access, food utilization and food stability of which eight indicators were identified for this study. The study aims to evaluate vulnerability to chronic food and nutrition insecurity, one of the food stability types, in Ethiopia; and examines the relationship between four food security dimensions
"Transportation" is believed to be one of the main essential elements for the development of human civilization. From road to rail and from sea to sky. Till now, we human have formed many varied modes of transport that we facilitate in our daily lives. It is inevitable that a place that gathered the more people, the greater consumption of transportation. Many demanding cities like Londo
