Large enterprises have diverse applications for different needs which is utilized over different number of applications. These applications cannot communicate with eachother frequently as it leads to slower productivity. The information needs to be exchanged in the organization for their seamless working so it is a major factor to consider this need of utilizing the information among different applications to run theprocess efficiently. In addition to this, there is also a need to represent this data thatis generated through this web service into a web application so that thedata can be clearly visualize in graphical format. Therefore, this research focuses on building a web service for an external application usage and representing that data into visualization format. It also involves using the Scania IT guidelines and thereference architecture for this implementation of web service.

Satellite link is a type of an unreliable network that is vulnerable to interferences such as disruptive foreign signals on the same frequencies, weather conditions, area coverage but mainly the distance from a satellite dish to the satellite itself. Some infrastructures, such as cruise ships, strongly rely on satellite internet and in the same time their applications require reliable data exchange with the shore-side serves. The unstable connection between two end points result in data loss due to high latency which causes dropped packets drops. This paper proposes solutions on software level to these problems.

As more intermittent, decentralized production and consumption sources are connected to power grids, new demands are put on operators in control rooms managing the grids. Managing the grids from a tele-operation perspective, operators are dependent on communication channels connecting them with the grids. As the information flows from communication channels are reflected by changes in the grid, they are getting more challenging to manage and be situation aware of. In this thesis, a user interface concept for communicating dynamic information flows in a situation awareness supportive way is developed and evaluated in terms of providing convenient pathways to information and supporting understanding of a situation. The concept was developed through an outsetting field study and a design process guided by design rationale. Findings indicate that the concept supports situation awareness in providing convenient pathways to information, and for supporting understanding of a situation both slight improvement and slight decline in situation awareness is seen. In conclusion, the concept provides a promising alternative in giving short cuts to information and in aggregation, but much less decisively, it also integrates information in a way that supports understanding of a situation.

There has been a revolution in US oil production the last decade,mainly because of production of the unconventional tight oil, and itis therefore of great interest to be able to produce reliableforecasts on future supply.The aim of this study is to develop and explore a bottom-up well-bywellmodel for tight oil production. The model is based on theinherent physics and geology of the well, together with simplemicro-economic principles. The model is made to be modular, flexibleand well grounded in practicalities. It successfully manages toreplicate historical production profile of Eagle Ford Play both withand without economic parameters. This implies the suitability of abottom-up approach for this kind of task.The model also tries to look into the future. An exploratorysimulation result suggests that a large decrease and stagnation indrilling capacity gives a convergence in oil production to aconstant level. But, the decrease in drilling capacity does notcorrespond with the decrease in oil production. Also, a low level offuture oil price could give a hyperbolic decline in production ratewhich does not seem to level off within years.

Just as there are markets for residences, vehicles and furnitures online, there are also webpages for buying and selling horses. A potential buyer for a horse is prepared to travel very far just to look at the horse that from the ad seems to be the perfect one. A short text and a few photos will not provide a comprehensive representation of the horse and unfortunately, the horse in question is not always as promised. The goal with Equitrade was to develop and improve the trade with horses through digital media focusing on user interaction and reliability. By integrating horses performance results from an external database on the webpage makes it possible for the users to be sure that the information in the ads is correct. With this feature, the information in the ads becomes reliable and creates a safer environment for users. To contribute to the usability, Equitrade has a comprehensive search and filtering feature, which creates flexibility for the users. Being able to filter using multiple search parameters makes the search process short and users can easily sort out ads that are not relevant to them. / Precis som bostäder, fordon och möbler kan en häst byta ägare via en annons på webben. Däremot är en potentiell hästköpare beredd att åka många mil för att enbart provrida den häst som till synes från annonsen verkar vara den perfekta. En kort informationstext och några bilder i en annons ger sällan en heltäckande bild av hästen och tyvärr är inte hästen ifråga alltid som den utlovats vara. Målet med Equitrade var att vidareutveckla och förbättra den digitala handeln med hästar genom en prototyp av en köp- och säljsida för hästar med fokus på kundnytta och trovärdighet. Genom att integrera tävlingsresultat från en extern databas på köp- och säljsidan kan köpare enkelt verifiera om det säljaren skrivit i annonsen stämmer. Med denna funktion blir informationen i annonserna tillförlitlig och skapar en tryggare miljö för användarna. För att bidra till kundnyttan har Equitrade en omfattande sök- och filtreringsfunktion, vilket skapar en flexibilitet för användarna. Att kunna filtrera med hjälp av ett flertal sökparametrar gör sökprocessen kort och användare kan enkelt sortera bort annonser som inte är relevanta för dem.

The project enables process control of healthcare equipment through the social network service Twitter. Machine operators should be able to control machines through their computer, tablet or mobile device, without physically having to be in contact with the machine. The project solution has been designed by programming against Twitter's application programming interface, that is, utilizing the functionality that Twitter offers. The reason is to use functionality that already exists and circumvent the maintenance of an application. The project has consolidated Twitter functionality with GE Healthcare's internal software system into a unique solution that enables remote control. / Projektet möjliggör processtyrning av maskiner inom hälso- och sjukvården via den sociala nätverkstjänsten Twitter. Maskinoperatörer ska kunna styra maskiner via deras dator, surfplatta eller mobila enhet, utan att närvara vid maskinen. Projektets lösning har konstruerats genom att programmera mot Twitters applikationsprogrammeringsgränssnitt, det vill säga ta del av funktionalitet som Twitter erbjuder. Anledningen är att använda funktionalitet som redan existerar samt kringgå underhållandet av en applikation. Projektet har sammansvetsat Twitter-funktionalitet med GE Healthcares interna mjukvarusystem till en unik lösning som möjliggör processtyrning på distans.

Decentralized solar energy is solar energy produced close to where it will be used, rather than at a large facility elsewhere and sent through the national grid. This project involves collecting data from decentralized solar facilities with data collection support, as well as visualizing the data in a format that is adjustable and understandable by everyone. The goal is to share knowledge about renewable energy sources, specifically solar panels and how these can be used in the most efficient way. The authors, together forming Sun Labs, developed a web application with capabilities such as graphing energy production from solar facilities. This visualization was done in a creative and intuitive environment for everyday users as well as professionals. Throughout the design process of the portal we designed for smaller screens first and the larger screens last. This philosophy is called mobile first design and was key to the development of the portal.  The evaluation methods of this project include: UX-testing, unittesting, interviews and manual testing. The evaluation results show that Sun Labs successfully implemented a cross-platform application with the aforementioned capabilities. / Decentraliserad solenergi är solenergi producerad där den är tänkt att användas, snarare än vid en avlägsen stor anläggning som sedan transporteras via det nationella nätet. Projektet omfattar insamling av data från decentraliserade solanläggningar med stöd för datainsamling, samt visualisering av data i ett format som är anpassningsbart och förståeligt för alla. Målet är att dela kunskap om förnybara energikällor, speciellt solpaneler och hur dessa kan användas mest effektivt. Författarna, som tillsammans bildat Sun Labs, utvecklade en webbapplikation med möjligheter att visualisera energiproduktion från solanläggningar i diagram. Denna visualisering gjordes på ett kreativt och intuitivt sätt för vardagliga användare såväl som professionella användare. Hela portalens designprocess konstruerades för mindre skärmar först, för att sedan anpassas till större skärmar. Denna filosofi kallas “mobile first”-design och låg till grund för portalens utveckling. Utvärderingsmetoderna för detta projekt har inkluderat: UX-testning, enhetstestning, intervjuer och manuell testning. Resultaten visar att Sun Labs framgångsrikt implementerat en plattformsoberoende applikation med ovan nämnda funktioner.

This master thesis was done at Uppsala Clinical Research Center (UCR). UCR have recently developed the technical platform QReg 5 for managing quality registries. UCR have been in contact with several international organizations interested in collaborating with UCR because of their expertise within quality registries as well as their technical competence. UCR have a complicated owner structure as well as organizational structure, as they are owned by Uppsala University and Uppsala County Council. The purpose of this master thesis was to present how QReg 5 could be commercialized under UCR's preconditions. In order for the internationalization plans to be successful, it was shown that the shared ownership of UCR needs to become clearer. By taking advantage of the possibilities with the new development section at UCR, the management of the contacts will be more efficient. Potential competitors for UCR are registry centers that have created their own technical solutions, large software companies, Life Science related organizations (e.g. hospitals), the organizations that UCR license QReg 5 to, as well as software companies creating electronic medical records. The most interesting customer segment for UCR are organizations with technical competences, which are placed in countries were quality registries are not yet in use.

The scope of this thesis is to investigate methods of recording, processing and analysing sound data from wheel brake testing in dynamometers with focus on detecting and measuring squeal. The desired outcome is a method that Scania can use to record and analyse brake sound. A literature study was made to find relevant methodologies and tools proposed in papers, books and industry standards. These methods were tried and evaluated by recording and analysing real sound data and other signals from one of Scanias dynamometers. The resulting method includes directions on what hardware to use, how to set it up and an algorithm that computes a spectral limit based on normal sound data. This limit is then used as reference when evaluating other recordings. To increase signal to noise ratio, an adaptive filter is proposed to attenuate background noise in the recordings, in particular from the dynamometer and ventilation system. The conclusion is that it is possible to find squeal using spectral limits based on normal data. The performance of the algorithm is a compromise between being very effective but rather complex, or slightly less effective but also less complex. Its performance is also highly dependent on how squeal is defined. A very narrow definition will only find certain types of squeal while a more broad definition will find more squeal, but also potentially mislabel some recordings.
