Popular Abstract in Swedish Lödda kompakta plattvärmeväxlare används i stor utsträckning i kyl – och värmepumpanläggningar samt luftkonditioneringsanläggningar. Såväl enfasvärmeutbyte, dvs värmeutbyte mellan två vätskor, som fasomvandling genom kondensation och förångning är viktiga tillämpningsområden. Apparaterna användes inom industri, hushåll, samhälleliga inrättningar mm. Prestandan för olikaThis thesis work presents various performance estimation methods of compact brazed plate heat exchangers (BPHE) operating in single phase, condenser, evaporator, cascaded and transcritical applications. Such methods play a vital role in development of heat exchanger selection software and during geometry parameter estimation in the new product development process. The suitability of employing comm

Life cycle assessment and life cycle cost analysis are suitable tools in trying to minimize environmental impact and cost. To get reliable results it is crucial to set up correct system boundaries for the investigation, but it is often difficult to understand a complex products system because of the cascade effects of consequences that can be induced even by small changes. In this paper the effect

Arktiska miljöer har de senaste decennierna upplevt en stark temperaturökning, vilket påverkar tundrans kolcykel.Smältande permafrost, minskande snötäcke och förändringar i hydrologiska mönster är exempel på pågående processer som förändrar samspelet mellan mark och atmosfär samt ekosystemens säsongsdynamik.Då ett antal av dessa processer involverar utbyte av växthusgaser, såsom spårgaserna metan Arctic environments have experienced strong warming in recent decades, which is affecting the carbon cycle of tundra ecosystems.Degrading permafrost, diminishing snow cover, and changing hydrology are examples of ongoing processes that affect the land-atmosphere interactions and seasonal ecosystem dynamics.Since a number of the affected processes involve the exchange of atmospheric greenhouse gase

Många processer i naturen går inte att förklara utan att gå ner på den molekylära skalan och studera enstaka laddningar som elektroner.Till exempel är laddningars rörelse i molekyler en viktig aspekt i fenomen som blixtar och norrsken. Ofta kan dessa processer bara uppstår när sammansättningen av atomer eller molekyler är på ett specifikt sätt; på samma vis som två hjul och en ram behöver sitta ihThe origin of properties in complex systems can often be traced to mechanisms involving charge and energy transfer in only a few embedded molecules. The detailed study of the time evolution of these mechanisms in their original environment is a challenging task. In this thesis we develop experimental tools and methods to enable the study of charge and energy transfer. A new ion and electron moment

The present work details a study of the 3D-modeling of dual-fuel engines, with a specific focus on medium speed marine engines. These operate under the fumigated approach, which means that the second fuel, which replaces most of the diesel fuel, is added in the intake duct. This type of engine requires the least amount of modifications to the current medium speed diesel engine and is therefore an

In Europe, Scandinavia holds the largest concentration of rock art (i.e. petroglyphs), created c. 5000–first century BC, many of them showing figurative and seemingly narrative representations. In this paper, we will discuss possible narratological approaches applied to these images. We might reasonably distinguish between three levels of pictorial narrativity: representations of (i) single eventsIn Europe, Scandinavia holds the largest concentration of rock art (i.e. petroglyphs), created c. 5000–first century bc, many of them showing figurative and seemingly narrative representations.

Abstract The focus of this thesis is to study and model the capacity of the bank to trade on the bonds market under normal and stressed conditions. This capacity is related to the liquidity of bonds market (ie, the ability to trade) and bank’s trading desks capacity to trade. All banks have different models but all are subject to the validation of the bank in a first place and the EU Central Bank

Naturlig språkbehandling och prostatacancer Naturlig språkbehandling är ett område inom maskininlärning för att förstå och generera text och tal. I detta arbete använder vi naturlig språkbehandling på patientjournaltexter relaterade till prostatacancer, för att klassificera dem samt extrahera relevant information. Prostatacancer är den vanligaste typen av cancer bland män och varje år dör 2400 i

Offentlig upphandling handlar om hur den offentliga sektorn ska agera vid inköp och har därmed en betydande påverkan på samhällsekonomin. Essentiella samhällsfunktioner som exempelvis sjukvård och skolor tillgodoses genom offentlig upphandling. Eftersom inköpen görs via skattemedel har samhällsmedborgare ett intresse av att förfarandet går rätt till. Vidare har leverantörer ett intresse av att förPublic procurement concerns how the public sector should act when making purchases and therefore has a great impact on the national economy. Fundamental societal functions such as healthcare and education are supported through public procurement. Because these purchases are made using tax revenue, citizens have an interest in ensuring that the procedure is conducted properly. Moreover, suppliers h

Tidigt under åren i arkitektskolan lär vi oss att forma och utforska våra egna kreativa processer. Dessa blir djupt personliga, och i detta projekt vill jag försöka formulera och utforska mitt sätt att arbeta. Under min studietid har jag upplevt att de största problemen jag haft under designprocessen varit att jag tenderat att bli för självkritisk i ett tidigt skede, vilket har resulterat i låsninIn the early years of architecture school, we learn to shape and explore our creative processes. These become deeply personal, and in this project I want to try defining and exploring my way of working. During my time as a student, I have experienced the biggest problems I had during the design process were that I tended to be too self-critical at an early stage, which resulted in blockages in the

Undersökning av inomhusmiljön i Bostadshus i Kurdistan med förslag på förbättringar Av Zahir Rashid Ibrahim Sammanfattning Den varma sommarsäsongen i Kurdistan är mycket lång och omgivningstemperaturen är cirka 45 ˚C. Byggnader kyls ner med luftkonditioneringssystem på sommaren och värms upp med eldrivna eller oljedrivna värmesystem på vintern. Oljedrivna placeras oftast i vardagsrummet Examination of indoor environment in dwellings in Kurdistan with suggestions on improvements By Zahir Rashid Ibrahim Summary The hot summer season in Kurdistan is very long and the ambient temperature is about 45 ˚C. Buildings are cooled by air conditioning systems in the summer and heated with electric or oil-fired heating systems in winter. Oil-driven are usually placed in the living roo

The aim of this master’s thesis is to examine how fiction authors seek information in their writing, which still is a vastly under-researched subject within Library and Information Science. Why then are there so few of us in this discipline who ask themselves which information behaviour and information needs that exist among the ones writing the literature filling our libraries? This study was car

There are plenty of IT-consultancy firms operating today, and the numbers show that they keep getting more and more. At the same time, the demand for these services are increasing. The biggest issue that these firms face today is related to finding new business opportunities. The complexity surrounding the purchase of these services make it a complex subject that is hard to fully grasp. It include

We think much of a current consumption is strongly based on various types of loans every person should have an idea about how the loan approval mechanism works. Because everybody wants to know if they have a possibility of getting a loan approval, almost all banks’ web pages have a maximum loan calculator, which gives a client a maximum loan amount he/she could borrow at a current date given certa
