Att ta tillvara på den stora mängd spillvärme vi producerar är idag högaktuellt. Ett sätt att göra detta är med hjälp av så kallade termoelement. I detta arbete undersöks ett termoelement som består av kvantprickar.A thermoelectric device is a solid-state heat engine that operates using the thermoelectric effect, which is the principle of direct conversion of heat energy to electric energy. Today the poor efficiency and relatively high production cost of thermoelectric devices heavily limits their applications. Most thermoelectric devices are built up of semiconductor thermocouples, which consist of an n-dop

Pluviala översvämningar inträffar när intensiteten av ett regn överskrider markens förmåga att infiltrera, vilket resulterar i att vattnet istället ansamlas på ytan. Tillräckligt mycket vatten på samma yta leder som bekant till översvämning. Ett typexempel är när korta intensiva regn faller över urbana områden där ytor som asfalt förhindrar infiltrering. Mängden och intensiteten av denna typ av övThe number and impacts of pluvial floods are likely to increase with the growth of our cities and as extreme weather is anticipated to intensify with climate change. Im- proved preparedness is needed which may be attained owing to recent development of high-resolution hydro-meteorological observations and forecasts as well as geographical data. This paper investigates the capacity of the HYPE mode

Purpose: The aim of this paper is to explore whether service can be implemented as limited edition in order to strengthen the brand and to drive business. Methodology/Approach: This research is based on a qualitative approach with a multi case study analyzing Visit Sweden, Finnair and Lund University. Each brand has implemented a limited service of own kind this year. Findings: The research sh

In markets with fierce competition and low switching costs, the capability to keep customers is just as important as the capability to get new customers. One of the cornerstones of efficiently keeping customers from churning is the ability to identify customers that are more prone to leaving the company than others. This way, churn prevention resources and measures can be efficiently directed towa

The aim of this thesis is to explore how young Swedes’ news habits and trust in the news media differ from the rest of the Swedish population. For this purpose we surveyed 134 high school students and compared the results with data from the 2019 edition of the Digital News Report, published by the Reuters Institute for the Study of Journalism. We found that young Swedes’ news consumption for the m

For children with blindness, ball games can be very challenging, as most ball games depend on quick perception of a multitude of things which are by people with good vision in general perceived through vision. The currently available aids for making ball games more accessible for people with blindness, most in the form of audible balls, leave room for improvement. The central aim in this thesis i

Bakgrund: Nyligen införde barnhälsovården i Region Skåne Språkfyran, ett validerat instrument för att upptäcka språkstörning hos fyraåringar. Språkstörning är en funktionsnedsättning där tidiga insatser har stor betydelse för individens fortsatta utveckling. Barnhälsovården behöver instrument av hög kvalitet för att uppfylla sitt uppdrag att upptäcka och agera vid problem i barns utveckling. Syfte

Plastic pollution is not a new thing, not a new thing at all. Actually, concern about plastic had been growing date back to 1960s, almost 60 years ago, when the plastic debris in the ocean was first observed, but now the global plastic production is still increasing, as well as the amount of the plastic waste that enters the ocean every year. I knew about plastic pollution since I was a kid -

Dominica, the hurricane-prone island nation, experienced severe destruction in September 2017 from a category 5 hurricane named Maria. Based on research and a minor field study to the island in the Lesser Antilles, a climate change adaptive and hurricane resilient design for a specific site in the capital Roseau is proposed in this master thesis project in Sustainable Urban Design. The project ai

There is not much that can compete with pre- paring and enjoying a meal, cooked to perfec- tion, in the company of friends. No matter how skilled you are at cooking or baking, it is impossible to achieve the same quality of bread and pizza as in a restaurant since a regular household oven will not genera- te the temperature or taste needed. To solve this I set out to design a way for homeowner

Hög personalomsättning är problematiskt i servicenäringen. Syfte med uppsatsen är att få en förståelse för vilka mekanismer som samverkar med frivillig personalomsättning i servicenäringen. Detta syftet ledde sedan till två frågeställningar: Finns det skillnad på vilken generation du tillhör och de mekanismer du anser samverka med frivillig personalomsättning och Varför ser det ut som det gör kopp

A large number of forest fires occurred in Sweden during the summer 2018 on a total area of 21 000 hectares. Between 300 and 500 residents were evacuated from their home due to these fires. This situation was unfamiliar in Sweden at the time, and the routines for dealing with such crisis were challenged. This thesis aimed to investigate the communication and information strategies, the evacuation

The phenomenon of global warming has become a fact, however; the uncertainty is about the magnitude and acceleration of its manifestations. Global mean sea level rise is one of the results induced by global warming and is happening with an undetectable accelerated pace. The world international organizations and governments are devoting efforts and initiatives in a trial to manage global warming in

Det övergripande syftet med uppsatsen är att undersöka och analysera de aktiebolagsrättsliga kapitalbristreglerna. Inledningsvis ger uppsatsen en övergripande bild av reglernas konstruktion. Fokus läggs sedan på den sen-aste rättsutvecklingen som skett på området med avseende ansvarsperiodens upphörande. Eftersom den senaste rättsutvecklingen bl.a. berört förhållandet mellan kapitalbristreglerna oThe overall purpose of the essay is to investigate and analyze the capital deficiency rules in the Swedish Companies Act. Initially, the essay provides an overall picture of the rules' construction. The focus is then placed on the latest legal developments that have taken place in the area regarding the expiry of the liability period. Since the most recent legal development concerned the relat

Romana mors (=Roman death) was the expression the Romans used for suicide since the Latin word suicidium didn’t exist in classical Latin and didn’t appear until the late Middle Ages. Such deaths were common among the upper classes in the 1st century B.C. and A.D., the two periods which I have drawn material from, and were considered as a noble way to end one’s life, a turning-point being Cato’s su

The aim of this bachelor thesis is to analyze advertising pictures from the high end brand Chanel in order to find myths surrounding their products. The images are chosen from when Karl Lagerfeld and Coco Chanel were creative directors, in order to find how the myths about Coco Chanel have been communicated over time and have helped the fashion house Chanel become successful within the industry. T

Ethiopia produces 86% of its electricity from hydropower source, still they experience frequent power shortages. As they are part of the East African Power Pool, this power shortage is usually made up for by buying energy from other members of the pool. Forecasting the energy available for usage in the future allows Ethiopia to buy energy ahead of time when prices are low, but also to sell surplus

Even though flying is the most unsustainable mode of transport due to its high contribution to global climate change (global warming), it is widely used and is predicted to increase considerably in the future. This goes against the global goal to reduce greenhouse gas (GHG) emission in order to reach the two-degree target set in the Paris Agreement. I am addressing this problem by looking into the

The white blood cell count and differential is an important part of diagnosing a number of medical conditions. Instead of doing this by manual microscopy, CellaVision’s technology has automated the process of finding and classifying white blood cells. To support a diagnosis it is desired that the system can produce cytoplasm-to-nucleus-ratio. This ratio is calculated from a segmented image where t
