The product H2 is a new heat exchanger produced, manufactured and sold by Heatex. It has an excellent surface efficiency, in large parts because of its slim features. The slim features does however have a drawback. It isn’t as mechanically stable and robust as its earlier cousins. The product tends to deform plastically in lifting conditions, especially the heavier versions needs extra support or,

Under flera års tid har återkommande förhöjda halter mikroorganismer förekommit i havremjöl på en av Lantmännen Cerealias verksamheter i Järna. Detta har lett till ett begränsat användningsområde och ökade kostnader. Syftet med utredningen var att upparbeta en åtgärdsplan för att förbättra hygienstatusen och minska de kostnader som de förhöjda halterna inneburit. Historisk data har granskats, en

Alten AB has a technology demonstator in the form of a motorized and camera equipped large scale labyrinth game. The ball position is controlled by a ABB industrial PLC connected with Android tablets for user interface and a camera as a sensor for the ball position. This thesis demonstrates the ability to place a wide angle camera inside the cabinet, correcting the lens distortion caused by the wi

The real estate market and stock market, as two major investment channels in China, had experienced dramatically skyrocketing and fluctuations. Especially, after 2008 financial crisis, the price index of these two asset markets tended to be alternately soaring and declining. It seems there is a new principle or new relationship generating between the real estate and stock markets. This study emplo

The purpose of this report is to evaluate a direct driven permanent magnet motor in high accuracy position and low speed operation. Actuation in this case is usually accomplished by stepping motors combined with belts and pulleys. High accuracy positioning is considered to be within 0.1 degrees and low speed 0.05 degrees per second, while at the same time have a 180 degree step response within 0.5

The paper investigates the relationship between population changes and public spending. The main interest is hereby whether local governments can adjust their public spending in times of population decline. A Swedish case study is conducted on all 290 municipalities in regard to their comprehensive school expenses between 2005 and 2013. The theoretical framework incorporates economies of scale and

I stygnen i våra kläder kan man ofta finna spår av barnarbete. Klädindustrin i Bangladesh är landets största exportsektor. Det är också den sektor där överträdelser av de mänskliga rättigheterna sker dagligen i förhållande till barnarbete. Olyckor i textilfabriker runt om i landet har orsakat flertalet dödsfall, vilket även tagit situationen gällande landets arbetsrättsliga förhållanden samt använIn the stitches of our clothes one can often find traces of child labour. The garment industry in Bangladesh is the country’s largest export sector. It is also a sector where sever human rights violations take place on a daily basis in relation to child labour. Accidents in textile factories in the country causing numerous deaths relatively recently brought the situation of working conditions to t

Effekten av temperatur på kaseinmicellstruktur i kaseinmicellkoncentrat. Anders Lindqvist: 2015 Med mål om att optimera produktionen av koncentrerade mjölkproteinlösningar och att få bättre kunskap om mjölkproteinet, kasein, och hur det påverkas av temperaturförändringar studerades förändringarna av koncentrerad mjölkproteinlösning efter att ha blivit utsatt för olika temperaturer. De förändrinThe viscosity of concentrated casein solutions play a vital part in the product quality of medical nutrition as well as for the energy consumption in spray drying. Previous work has shown that a lower viscosity can be achieved through processing (Hemar et al. 2011). This project focused on the effect on temperatures on micellar casein isolate (MCI). A temperature range of 5-90 °C has been studied

Abstract: This paper tried to investigate the internet, in particular mobile internet and mobile application economy in China through theories like catching up, disruptive technologies and leapfrogging concept. The unique development of mobile internet and mobile application economy in China facilitate the motivation to investigate the fundamental characteristics and stories behind mobile app mark

Drift av kärnkraftverk och andra kärntekniska anläggningar resulterar i radioaktivt avfall. Att mäta och karakterisera detta avfall finns det ett stort behov av då en tunna med radioaktivt avfall hamnar i olika förvar beroende på hur högaktivt och långlivat innehållet är. Visar det sig att avfallet är tillräckligt lågaktivt kan innehållet friklassas, d.v.s. att hantering/användning av materialet kIn order to store radioactive waste its contents need to be known. Determining radioactive waste can be achieved by different means. The most common method is using a detector to measure the gamma photons produced by the radionuclides in the waste. A widely used method is Segmented Gamma Scanning, in which the waste package is rotated in front of a detector and then raised to the next vertical seg

The Theory of Characteristic Modes (TCM) provides an alternative means of antenna synthesis in compact mobile handsets by taking into account the chassis. This makes it possible to create dual-element Multiple-Input Multiple-Output (MIMO) antennas in mobile handsets with very little coupling and correlation between the two antennas. But apart from the antennas, modern mobile phones are each equipp

Motivated by the phenomenon of one laptop per child in education at high-school level in the Swedish public sector, this master’s thesis elaborates on the question of ethics in public consumption. My research aims to show that collective actors such as municipalities can be seen as (un)ethical consumers and that they need to become aware of this. What I find problematic is the underlying processes
