A user interface should be intuitive to allow efficient and safe execution of tasks. Helicopter 14 (HKP 14) has operator consoles with an analog user interface, called Programmable Keys (PK), to control a Mission Management System (MMS). The idea of replacing the PK with touch technology has arisen. To understand operators’ working environment, this case study was conducted with inspiration from ethnography. The PK have been studied by reading system manuals and familiarizing with the MMS in Saab’s test rigs and in HKP 14. This study aims to investigate the opportunities and challenges with implementing a touch screen to replace the current PK. Interviews have been conducted with operators and one technician working with HKP 14. To highlight additional perspectives on usage of touch technology, interviews with employees at FMV and Saab were carried out. This study found both benefits and drawbacks with implementing a touch screen in the helicopter. The most common concern was that touch screens lack tactile feedback. This study exemplifies how physical support can be achieved on a touch screen and how a Graphical User Interface (GUI) can be designed with regards to this. / Se filen

Les appareils mobiles intelligents occupent désormais une place importante dans la vie de tous les jours. En plus de répondre aux besoins multiformes des utilisateurs, ils permettent l'intégration de nouveaux supports informatifs dans le développement de plusieurs secteurs, dont celui du tourisme. L'objectif de cette étude est d'élaborer un outil d'aide à la décision qui mène à la création d'un modèle théorique de développement pour l'adaptation d'une application mobile à l'une des routes touristiques signalisées du Québec : la Route des Sommets.

The significance of teaching the basics of engineering education in middle- and high-schools is generally acknowledged by policy makers, teachers and researchers in the U.S.A. as well as a number of developed and developing countries. Nevertheless, engineering topics are rarely covered by precollege curriculums. A key contributing factor is that engineering hinges on the usage of technology to expose learners to fundamental concepts otherwise difficult to demonstrate. For example, learning the concepts of systems' design, optimization, and trade-offs can be a challenging task when teachers and students limited access to tools to practice their engineering knowledge. Thus, a deficiency of operational learning technologies for diverse precollege environments affects the availability of engineering learning experiences. The aim of this dissertation is to unveil the relationships between influential factors for the advancement of precollege engineering education. We proposed a framework for the development of curriculum and technology derived from analyzing design issues from the perspective of multiple entities encompassing a broad of stage holders including students, teachers and technology developers. Several influential factors are considered including human-computer interaction issues, the problem of a digitally divided population and the lack of engineering curriculum that reconciles precollege engineering education with state and national educational standards. The findings of this dissertation are based on quantitative and qualitative re- search performed during a four year span working with five local schools in the Tucson Unified School District.

ssuring production forms a crucial part of mining business profitability. Factors related to various mine operations, activities and business processes can threaten required/planned mine production.   To address problems and ensure production level in mining, it is necessary to implement a mine production assurance program (MPA). In order to propose a guideline and its component, this study started by reviewing four such techniques used in process industries. Comparing the tools, techniques   and focus with mining productivity and production factors, it was observed that applicability of these methods for mining is limited due to lack of focus on equipment focus, cost focus and other parameters. Similarity of objectives and requirements of equipment focus lead to conclusion that PAP from oil and gas industry seems to be method which can guide MPA.\parAs a basis of MPA, an index is required to create a clear relationship between different situations which can occur in mining operation and production loss. A literature review on mining productivity improvement methods shows availability, utilisation and production performance of equipment are the key factors in determining overall production. A single index applicable for chain operation in mining is needed. A Mine Production index (MPi) is thus proposed. This index involves all three parameters for equipment productivity mentioned above.  Weights associated with MPi calculation for bottleneck equipment can point out critical factors in equipment operation. Once bottleneck equipment and relevant critical factors are known, further analysis can be carried out to determine the possible causes of production loss. By using MPi for machine operations, it is possible to rank machines in terms of production effectiveness. When the study applied MPi to chain operations in a mining case study, a crusher was determined as bottleneck equipment.\parMining operation is heavily influenced by internal and external uncertainties. Operational uncertainties related to equipment includes its key factors leading to production i.e. availability, utilisation and performance. These factors are in turn dependent upon downtime, idle time, rated capacities. External parameters related to weather are based upon location of mining operation. Influence of these factors on production volume, could be used for better decision making during mining operations optimization. To effectively propose a method for correlating internal and external parameters with production volume, case studies in an open pit mine were conducted. During these case studies a multi-regression modelling methodology is used. It was found that at system level availability is important criteria for increasing production. At level of shovel and truck fleet, availability and utilisation are most important characteristics to be focused for reduction in production uncertainty. Environmental factors are although correlate to less variation in production volume compared to operational factors.  Amongst considered environmental factors snowfall is highly influencing followed by rainfall.  At system level  use of maximum capacities of equipment and availability are key point for increasing production. Based on analysis of internal operational factors, it was concluded that capacity of shovel and trucks is underutilised. For shovels availability and idle time are influential factors. For trucks utilisation is highly correlated to production volume generated.  Analysis of environmental factors concluded that, period of zero snowfall and rainfall are perfect condition for equipment production increase. Period when either snowfall or rainfall stabilisation are also equivalent to achieve higher production. Although these production levels are significantly less than period without snow and rain

Photovoltaic (PV) system and the battery energy storage system are promising to supply power for residential buildings. Solar panels along with the battery energy storage (BESS) presents an opportunity for the households to use a much greater proportion of the solar photovoltaic (PV) to generate the electricity and minimize the need of purchasing expensive electricity from the electricity grid. This project presents a framework for conducting the economic and technical analysis of residential house along with the integration of solar panel units and the BESSs. In this study, the electricity consumption of a multi flats building (Magnolia) in Helsingborg and the PV production profile under local weather conditions are compared and analyzed. The proposed framework is developed by considering different prices of electricity of the existing electricity market in Sweden as well as the investment costs for the solar PV units and BESSs. The economic analysis is carried out based on different economic measures such as electricity price, simple payback analysis, net present value, payback analysis based on funding and without funding, and reduction in carbon-di-oxide (CO2) emissions. Technical evaluations of the BESS are carried out based on peak shaving purpose and overproduction from the solar panels. and The results show that ten 28 kWh of the BESSs in Magnolia building is required in order to meet the customer electricity demand and reduce the stress on the electricity grid as well as power cost and size of the fuse. Furthermore, the customer saves 154256 kr yearly, with the payback period of 14 to 20 years, which is almost similar to the expected lifetime of such a BESS.

L'institution judiciaire en général et le procès civil en particulier ne sont pas épargnés par le mouvement de la dématérialisation qui touche de nombreux secteurs du service public. En effet, l'introduction des TIC dans le procès civil a été motivée principalement par la quête de la célérité et de l'efficacité de ce dernier. Toutefois, il faudrait contrebalancer ces deux objectifs recherchés avec l'exigence du respect des garanties procédurales et institutionnelles des justiciables. Car, la recherche d'accélération du temps judiciaire et la réalisation d'économie de moyens alloués à ce service ne doivent pas l'emporter sur la qualité des jugements civils. La conciliation de ces trois exigences se révèle comme l'obstacle majeur qui freine le processus d'intégration des TIC dans le procès civil. Néanmoins, tout est question d'équilibre : la technique informatique ne doit pas l'emporter sur la technique juridique et sur l'esprit même de la justice. L'essentiel, c'est que authenticité et modernité riment ensemble. / The justice system in general and the civil suit in particular not been spared by the movement of dematerialisation wich has affected many areas of public service. In fact, the introduction of ICT in the civil suit was fueled primarily by the quest for speed and efficiency. However, the need arose to balance these two objectives with the requirement of compliance with procedural and institutional guarantees for a fair trial. This is because the quest to accelerate judicial time and save resources allocated to this service sould not undermine the quality of civil judgments. Reconciling these three requirements is revealed as the major obstacle hindering the process of ICT integration in civil suits. Nevertheless, it is all about balance: computer technology should not prevail over the legal system and the spirit of justice. It is essential the authenticity and modernity go hand in hand.

Masonite Beams is a company that produces I-beams. They are also working on developing a building system for industrial production of building components. A part of their building system is a composite floor, consisting of LVL and I-beams. At the moment they are working with a new type of joint between floor and wall, where the connection between floor and wall will be solved by a protrusion of the LVL being placed of a hanger mounted on the wall. The aim for this project was to find a screw pattern where the resistance of the protrusion is enough to handle the support reaction that can occure. A screw pattern that would be capable to manage the support reaction was derived by practical tests, done in Masonite Beams lab. When a screw pattern with a capacity high enough for the support reactions had been found, 5 samples of the same screw pattern were tested to be able to calculate a characteristic resistance. During the testing the performance of the included components were also evaluated. The support reaction that floor potentially could be exposed to was calculated to 6,25 kN, a value lower than the resistance, that was calculated to 7,27 kN.

As a result of trends identified in the report and marketing plan, the importance of a search engine optimized platform for e-commerce is established. In order to further examine the implementation of such, a website was constructed with this purpose in mind. The of said website was designed based on user stories which in their turn partly came from competitor's websites and partly from preference. In order to optimize the website for search engines, four established factors were optimized to the best of the group's ability. These factors were responsivity, custom 404-page, sitemap and keywords. Testing these factors against Google, the tests were ran partly through the search engine itself and partly through the third-party programmes WebSite Auditor and SERPROBOT. In accordance with expectations, the keywords had a considerable effect on the acquired results, but the remaining factors had nothing more than a marginal contribution; this was not expected. The experiment had many sources of error and and low reliability, cheifly on account of the chosen instruments for measure and a statistical uncertainty as a result of few observations. The conclusion made is that keywords have a greater effect than the other evaluated factors.
