Today?s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value.This thesis exams a new method to calculate the volume in tanks by using sensor fusion to crosscheck the i formation from the level sensors when the vehicle is tilted. The information is then used to see if it is possible to identify the grade of tilt by the change of fluid level. If the grade of tilt can be measured then the volume can be calculated in a more accurate way.

In the process of making carton boards into Skoghall Mill, are great quantities of water being contaminated. This water has to be treated before it is possible to release into the recipient, Kattfjorden. One of the contaminations that is important to extract from the wastewater, is organic carbon (measured as TOC-total organic carbon) because microbiological breakdown can lead to the bottom becomig free of oxygen.The wastewater treatment at Skoghall Mill is done through an external wastewater treatment that is located at the factory. The biological treatment (aerated lagoon) is a 140 000 m3 water pool with surface aerator, which is give oxygen to the water. In the lagoon live microorganisms who performs the biggest part of the TOC-reduction.One problem with the lagoon is that the treatment of TOC is considerably worse during wintertime than during summertime.

The overall purpose of this essay is to come to a deeper understanding about videos in the Youtube beauty community by using a mixture of qualitative and quantitative methods. By answering the main questions of the essay which are; What quantitatively measurable components are there in the videos that can be seen as contributing factors leading to the fact that some generate more views that others?; Is there a set mold for success containing certain aspects that a video must have to stand out?; What correlations can be found between the two categories of analysis and how do these potential correlations affect the popularity of the video? and What effects do specific components on the level of popularity of the video?, we?ve been able to distinguish differences as well as similarities on both qualitative and quantitative levels. We have also seen that using the two methods together have enabled us to reach more profound results. The main result that we have found on a quantitative level is that there are obvious correlations between a high level of popularity and a good visual quality.

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

After the formation of the European Union internal market in 1992, member state specific obstacles and barriers were largely removed. This was especially the case in harmonised industries where standardisation and technical regulation have led to legal certainty. Despite this, a large range of trade regulation continues to remain distortional to trade, in addition to the ongoing tariffs and subsidies. The key trade regulations relate to a number of areas involving technical regulations such as production labelling and the protection of intellectual property rights. Whilst policy makers claim justification based around the need to correct market failure in delivering desired outcomes, the question is whether these regulations are appropriate responses to market failures or if they have simply been imposed in an attempt to protect domestic markets.

Global warming is generally recognized as one of the major environmental challenges we have to face in the near future. The students in school today are the ones that will have to deal with the consequences of it tomorrow. That is why education about it is so important. Previous research shows that students believe that environmental issues in general are important problems to be solved. I this study I tested students in grade twelve, in four different schools in order to find out what their level of knowledge about global warming is, how worried they are about it and if there are any correlation between their knowledge and their level of worry.

At seed-growing the aim is to produce a commodity with high germination capacity, good soundness and purity, and also slight admixture of seeds from other species. The capacity of germination and the vigour of the seeds may become impaired in consequence of mechanical damage, infection of diseases, growth of mould, attacks of vermin, high drying temperature, secret germination, sprouting in the ears etc. The germ belongs to the outer and most unprotected parts of the seed, and consequently this is much exposed. Even quite sound seeds can instantaneously have low capability of germination. It can be due to the fact that the seeds are in rest of germination, i.e.

ITT Water & Wastewater ställer höga krav på kostnadseffektiv produktion vilket är en starkt bidragande orsak till att företaget är världsledande på sin marknad. För att erhålla kostnadseffektiv produktion har kombinationen människa robot visat sig vara framgångsrik.Examensarbetets syfte var att ta fram underlag åt ITT Water & Wastewater för att ta beslut om frigörande av indirekt personal vid line 15:s isoleringsstation på Elmotorverkstaden. Syftets uppfyllande stöttades av de underbyggande syftena att försöka höja robotens utnyttjandegrad samt reducera isoleringsmaskinens omställningstid.Arbetet bygger på kvalitativa och kvantitativa data i form av mätningar, intervjuer och egna observationer. Med stöd av erhållen data lyftes fyra olika förslag fram. Förslagen understryktes bland annat av integrering av arbetsmoment, förhöjd automatiseringsgrad och outsourcing..

Mastitis, an inflammation of the udder mainly caused by a bacterial infection, induces an increase in the somatic cell count (SCC) in milk and is consequently one of several factors affecting SCC in milk. In this literature review it is investigated whether SCC; on udder quarter, cow composite or bulk tank milk level, can be used as a quality marker with focus on milk composition in terms of the content of fat, lactose, total protein, casein and whey protein. According to this literature review the relation between SCC and milk composition is not reliable either on udder quarter, cow composite or bulk tank milk level. SCC was related to lactose, casein and whey protein on udder quarter level; lactose and whey protein on cow composite level and lactose on bulk tank milk level.

The hospital in Varberg has a somewhat outmoded solution regarding the state of preparedness in its water sustentation. Today?s solution is both cause to a number of mishaps and high energy consumption.The report is initiated by looking into the present situation to get an insight to the problem.Today?s media depletion is measured and analyzed.Furthermore, it also looks into some earlier performed studies. These studies are followed up in order to see if measures have been taken.The report presents a number of arrangements which should be taken, amongst those a minor re-build of the current solution and a number of arrangements which leads to decreased water consumption..

Hylocomium splendens (Glittering wood-moss) is a common species in the Nordic countries and can be found in many different types of boreal forests. It usually forms dense moss carpets on the forest floor. The shoots grow in segments and new segments form annually on the previous years growth. The size of the segments is probably regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H.

AbstractSurface-water includes different kinds of pollutants from traffic and roads. To prevent these pollutants to reach nearby lakes one can construct surface-water ponds on locations with heavy traffic. At Bergviks shopping centre in Karlstad, two ponds, one smaller and one bigger has been constructed in order to decrease the pollutant pressure from the receiving waters of Kattfjorden. Several heavy metals are essential for plants and animals in low concentration but when they occur in higher concentrations, they become toxic to the organism. The larger pond at Bergviks shopping centre has a sedimentation function so the heavy metals sink to the bottom thereby not releasing directly in to Kattfjorden.

Vattendirektivets (2000/60/EG) krav på skydd och bevarande av vattenkvalitet i vattenförekomster har kraftigt ökat medvetenheten om vattenhänsyn och vattenvård i det svenska skogsbruket. Världsnaturfonden lanserade hösten 2011 tillsammans med skogsägarföreningarna (Södra skogsägarna, Mellanskog, Norrskog och Norra skogsägarna) vattenhänsynsverktygen NPK+ (Naturvärde, Påverkan, Känslighet och Plusvärde) och blå målklassning som hjälpmedel till skogsägare för att ta och synliggöra vattenhänsynen. Relevansen hos verktygen NPK+ och blå målklassning att identifiera och klassificera vattendrag efter vattenkvalitet undersöktes med antalet fiskarter som indikator på vattenkvaliteten. 55 vattendrag i Krycklanåns avrinningsområde strax utanför Vindeln i Västerbottens inland inventerades med NPK+ och blå målklassning i mitten av september 2011. Fältinventeringsdata analyserades statistiskt med fiskartsförekomst från en tidigare elfiskeinventering i vattendragen.

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.
