A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.

With the expansion of the internet, the conditions for the online journalists have changed. Feedback is faster and more blatant than offline. The online abilities of anonymity and dispersion attracts people to both use and misuse. During 2013, the online expressions of hate towards women has been brought to attention in the media more than ever before. Nevertheless, the phenomenon is far from new.Our qualitative research including interviews intends to find out how the afflicted women journalists are affected in their exercise of their profession.

Den här experimentella studien undersökte huruvida man kan skyddas från bakgrundstal genom att använda sig av ett annorlunda teckensnitt än det man vanligtvis läser. Trettiotvå försöksdeltagare deltog i experimentet. Deltagarnas uppgift var att minnas information från texter om två påhittade folkslag som antingen var skriven med ett vanligt teckensnitt (Times New Roman) eller ett annorlunda teckensnitt (Haettenschweiler) i två ljudbetingelser: tystnad och irrelevant bakgrundstal. Resultatet visade att försöksdeltagarnas prestation på läsminnestestet försämrades av bakgrundstalet när texten de skulle minnas var skriven med Times New Roman, men inte när texten var skriven med Haettenschweiler. Det tyder på att man kan skyddas från att bli distraherad av bakgrundstal när man läser kortare texter skrivna med ett annorlunda teckensnitt, vilket kan vara en enkel lösning att använda i ett kontorslandskap..

The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..

In latter years there has been a discussion about the increasing importance of intangible assets and how to incorporate this fact into strategies, accounting and valuation. The ?Internet-bubble? is a recent event that drew much attention to intangible assets, and was an indicator of how complex it can be to value assets in general and intangible information in particular. Legislators recently addressed this issue by introducing IFRS3, which led to an update of IAS38, which in turn revised the methods for handling intangible assets. A specific intangible asset that has caused much debate is research and development (R&D), since it is commonly not allowed to be realized as an asset, which could cause implications concerning analysis and valuation.

Hypertrophic cardiomyopathy (HCM) is the most commonly diagnosed cardiac disease in cats. The phenotype varies from mild focal thickening to severe concentric hypertrophy at the left ventricle. Two separate myosin binding protein C (MYBPC3) mutations have been identified in Maine coon cats (A31P and A74T) and one in Ragdoll cats. All three of them seem to cause familial HCM in an autosomal dominant pattern. The purpose of this study was to investigate the presence of these three mutations in population cats of different breeds with HCM in Sweden. The results may show if HCM is present in the absence of these mutations.

Att interagera med ett system genom att använda naturligtspråk görs genom att använda ett Natural Language Interface (NLI) som innebär svårigheter för både system och användare. Syftet med denna studie var att undersöka om taligenkänning är en användbar inmatningsmetod för naturligt språk baserat på ISO-definitionen av användbarhet. Detta gjordes genom att utveckla ett spel baserat på det klassiska textbaserade spelet Zork där användaren ger kommandon i naturligt språk som sedan användes för en användbarhetsstudie. Studien utfördes med mellangruppsdesign med två grupper av användare där den ena gruppen använde tangentbordsinmatning och den andra taligenkänning med Web Speech API. Både kvalitativ och kvantitativ data insamlades under testet om användarnas effektivitet, beteende och uppfattning av systemet.

The automotive industry is increasingly studying lightweight solution in their designs, also rational production and low costs in materials and manufacturing methods are of great interest. This thesis consisted in the practical evaluation of anchors for sandwich panels. The object was to study loads of shearing and pull out of the plane. The experiments were carried out on panels made up of 1mm aluminium coatings and 50mm extruded polystyrene (XPS) at its core. As the fasteners used simple methods such as blind rivets, screw and glue.

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.

Cuttings of Lonicera xylosteum L. were treated with willow extract to study the response in rooting capacity. The extracts were prepared by mixing chopped pieces of Salix x smithiana Willd. with water in a warring blender. The investigation comprised 2 types of salix extracts based on differences and dynamics between twigs in winter dormancy and twigs with new shoots. To explore the rooting response, three tests were made.

Denna uppsats tar upp frågan om en teknisk artefakt, i detta fall läs- och/eller surfplatta, kan ses som en bra lösning för dyslektiker i deras svårigheter med läsningen. Studien har fokus på läs- och surfplattans funktioner som kan vara en möjlighet att hjälpa personer med läsning. Uppsatsens experiment beprövar en redan etablerad metod, läsa och lyssna samtidigt, genom att sätta samman ett antal funktioner och tekniker som finns idag i en enhet. Vi har undersökt om man kan öka läshastigheten och läsförståelsen hos dyslektiker med hjälp av sådan teknik på en läs/surfplatta. Resultatet visar en trend på att metoden fungerar.

Fossil fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.

The society today is more aware of the importance of early diagnosis of children?s hearing impairment. Neonatal hearing screening is used in many countries today, that is to be able to start habilitation at as early age as possible. Studies have shown that if children are diagnosed early enough will their language ability follow the age group of normal hearing peers.This is a journal study where journals form 99 Icelandic children, diagnosed in the Hearing and Speech Institute of Iceland during a period of 5 years, between 2002 and 2006, were inspected and analyzed. At the same time as the age of diagnose was analyzed the influence of gender, type and degree of hearing impairment was inspected.The age of diagnose of hearing impairment in Iceland was found to be between 5 and 6 years of age which looks higher than in other counties.

When is it acceptable to make fun of religion, and when does it become disrespectful? On January 7, 2015, the headquarters of the French satirical news paper Charlie Hebdo was subjected to a terrorist attack that claimed the lives of 12 staff members, due to the publishing of caricatures picturing the prophet Muhammed. The reactions that followed the attack circled around two perspectives; the importance of freedom of expression and the obligation to show respect for certain institutions and traditions in society. How come the caricatures can elicit such completely different reactions? This is the question that this thesis uses as a starting point for the examination of the subject caricatures and satire.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
