I en teoretisk studie har användbarheten av thermosyphoner för att förbättra säkerheten och effektiviseringen av kemiska reaktorer. Thermosyphoner är en simpel form av en ”heat pipe”, ett ihåligt och slutet rör som är delvis fyllt av en fluid. Om röret värms upp till fluidens kokpunkt inleds en inre fasomvandling vilket används för att förbättra rörets värmeledningsförmåga. Tre simuleringsmodellerIn a theoretical study the use of thermosyphons to improve the safety and efficiency of chem-ical reactors have been evaluated. Thermosyphons is a simple form of a “heat pipe”, a hollow and closed tube that’s partially filled with a fluid. When the pipe is heated up to the boiling temperature of the fluid within a phase change is initiated. The phase-change is used to im-prove the thermal conducti

In this master thesis it's concluded that Swedish municipalities performs various traffic data collections in recurring measurement points annually and beside those complementing measurements are done at additional areas of interest. The study shows that most often traditional measurement methods, like pneumatic tubes, are used since they are considered reliable and accurate. Pneumatic tubes,

Democratic transitions have been associated with a high level of economic development and good economic performance according to modernization theory. However, until now no consensus has been reached about the specific form of the relationship. Thus, this study attempts to examine whether these suggested linkages hold evidence for the case example of Latin America by testing a linear as well as a

The Pacific Island countries face a host of unique and urgent development challenges that have historically provided the impetus for pursuing various forms of regionalism. This study seeks to shed new light on these processes by examining how the low levels of institutional and governance capacity of regional actors has influenced the success of institutional development strategies within the broa

CONNECT is an interactive meeting point were people, as strangers, lovers or friends have the chance to interact with each other. The project has strong connections to philosophical ideas, and interfaces with my personal reflections and the thoughts of an external audience. The aim of the project is to expand people’s minds and ability to be present and thankful. It questions social structures in

The starting point of this project was to find a way to transfer Chinese traditional culture into modern product. After pre-stage research about combining Chinese elements with products, I found a very interesting phenomenon of Latticed window, which brought me to another perception. I found out that people always ignore the subtle changes in daily life. These changes influence the relationship am

In the later Middle Ages there was a vivid activity of preaching at the Abbey of Vadstena. Apart from the ordinary Sunday preaching at High Mass, or in connection to it, there were a number of feasts due to the saints. At heart of the medieval pastoral theology was The Way of Salvation and the conundrum was how to make people understand how to correct their living in order to get into Heaven as qu

Purpose: The purpose of this paper was to discover the different ways to organize ambidexterity, and investigate what role MCS plays in the contribution of achieving the balance of organizational ambidexterity. We sought to create a theoretical framework that conceptualizes the relations between MCS and different forms of ambidexterity, based on both previous literature and a case study of IKEA f

Syftet med uppsatsen är att förklara hur crowdshippingföretag arbetar för att skapa förtroende och tillit för crowdshipping genom att studera företagens tilltiskapandeprocesser samt deras syn på tillit. Detta har vi studerat närmare med hjälp av följande frågeställningar: Vilka tillitsskapande processer tillämpar crowdshippingföretagen? och Hur ser crowdshippingföretag på tillit? För att besvara d

Previous studies have provided detailed recommendations regarding the design of flashing lights at emergency exit portals in road tunnels. Theory of Affordances have assisted safety designers fixing characteristics such as color, flashing rate, type and number of lights in emergency systems. A systematic evaluation through experiments has, additionally, provide stronger support to define these cha

Nima is a distressed neighbourhood located north of central Accra, the capital city of Ghana in West Africa. Nima is an extremely dense community, where land is very scarce. Single floor, clay built compound houses occupy the entire neighbourhood. Spatial planning is lacking, infrastructure is limited and overcrowding proposes a severe problem. Nima, a neighbourhood which is a direct result of rap

This work aims to explore the relationship between innovation and inequality, specificly in Brazil in the last decade. Innovation in one hand t is an unquestioned driver of growth, while inequality in the other is a major economic problem, one that arguably hinders growth. Using literature review and three types of analysis, (1) the global innovation index together with the world bank gini index,

Världen står inför allvarliga och komplexa konsekvenser när det gäller klimatförändringar. Naturliga och mänskliga bosättningar på samtliga kontinenter är påverkade, och den afrikanska kontinenten anses höra till ett av världens mest utsatta områden bland annat på grund av snabb befolkningstillväxt och stort beroende av regn-bevattnat jordbruk. Denna uppsats handlar om klimatförändringar i Kenya. The world is facing serious and complex impacts with regard to climate change. Natural and human settlements on all continents are affected, and the African continent is considered as one of the most vulnerable areas due to rapid urbanization growth and high dependency on rain-fed agriculture, amongst others. This thesis focuses on climate change in Kenya. The first aim is to compare trends of cli

Strike-slip faults pose significant earthquake hazards in many populated areas and therefore information about their general behavior is needed in order to attempt to predict future earthquakes. Much of this information is acquired using paleoseismic techniques, which focus on analyzing past earthquakes. These include measurement of displacements of either geomorphic features or beds across faults

Product quality is a major concern for all companies. Predicting the lifetime return rate allows for identification of products with atypically high return rates. Such products might otherwise not have been detected before it is too late to take any action to reduce the return rate. Furthermore, predicting a product’s return rate allows for estimation of the company’s expected cost of handling ret

This thesis will examine the plausibility of exchanging protocol from a normal server-client to a peer-to-peer solution for over-the-air updates, using a single case study for Sony Mobile Communications AB in Lund, Sweden. It will examine the effort, the risks, and what the actual gain may be comparing to a client-server approach for over-the-air software updates. Sony Mobile today uses a content

Abstract Introduction: Smoking is a major public health concern, accounting for nearly 700,000 deaths on an annual basis, globally. The socio-economic differences within smoking are well established, reflected in a social gradient that is estimated to account for half of the socio- economic differences in mortality for men aged 35-69 years in developed settings, such as the European region.
