SMS för personer med kognitiva och kommunikativa funktionsnedsättningar ? en intervjustudie av användares upplevelser
Current technology offers many possibilities for remotecommunication. Nevertheless, people with cognitive and communicativedisabilities have limited access to common communication technology like textmessaging via a mobile phone. This study is part of the project Text messagingwith picture symbols - a possibility for AAC users and people with cognitiveimpairments. Semi structured interviews were used to investigate three menand four women?s experiences of using Windows mobiles with adaptedfunctions for text messaging.
En bild säger mer än tusen ord, eller?: en studie om inferens
Without being aware of it, cognitive processes continuously take place in our heads. We are forced to fill in the information gaps that we meet in our everyday life in order to create an understanding and to form a whole, and that?s where the importance of inference comes in. To create inference implies creating meaning from something that is not explicitly given. Having knowledge about this process offers great possibilities, while not taking it into account may involve risks.
Analys av spänningsstabilitetsberäkningar i det svenska elsystemet
Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.
Buntning av grot med lastbilsmonterad utrustning :
During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.
Samsyn som grund till förändring? : En studie om vad som skapar samsyn och dess betydelse i förändringsprocesser
Globalization has among other tendencies led to the emergence of new ways of doing business. One of the ways for organizations to meet the demands of a new competitive landscape has been through management accounting change, a field which has become increasingly popular in research. This paper builds on that research and seeks to investigate the case of the implementation of a new management accounting system in a Swedish company which was triggered by strategic change. Commonality through the interactive approach is by some researchers seen as a key to successful change. This approach is contrasted to the importance of symbolic constructs and change recipients? cognitive effort to understand the meaning of change for which Framing theory is applied.
Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie
The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

Lämna inte slumpen åt slumpen - En studie om hylloptimering i den digitala butiken
This paper examines the impact of conscious shelf management on online grocery stores. An S-O-R framework is used to unveil if some established shelf management techniques from physical stores are applicable in an online context. We also explain some of the cognitive processes customers experience as they get exposed to online buying situations. A main study with two data sources is conducted: one quantitative website experiment with 168 participants who got exposed to five different organisation patterns within five different categories; and one more qualitative eye tracking experiment with 20 participants. The results indicate that a disorganised product page evokes not only different scan paths and cognitive patterns but also generates higher sales.
Eurokoder : en jämförelse mot BKR
In Sweden there are currently two separate guidelines you may use whenperforming calculations on frameworks, BKR and the Eurocodes. Although at theend of 2010 you are not allowed to use BKR any longer and only the Eurocodeswill be viable. The aim of this thesis is to explain how the Eurocodes and EKS work and alsohow they compare to the current guideline BKR. Similarities and differencesbetween these guidelines are also discussed so that the reader will get a betterunderstanding of how the Eurocodes are applied. The areas discussed are asfollows:Principles and adviceSafety ClassesSymbols and IndexesLifespanLoads and partial coefficientThe thesis also deals with the impact that this transition into a new guideline willhave on corporations, guideline costs, education and computer software. As anexample a rough estimate on what costs this transition will create on a companywith 20 employees is also included. Calculations have been performed in order to investigate how the design valuesdiffer between the two guidelines, the Eurocodes and BKR.
Representativa testnät försvenska eldistributionsnät
This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.
Kyla i Nyköping och Motala : Kartläggning av kylapotential för Vattenfall Värm
The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.
Doktorander i fysik söker information : en intervjuundersökning av forskarens första tid som informationssökare
The aim of this Master's thesis is to examine difficulties concerning information acquisition, use, and management experienced by graduate students in physics during their first years of research work. Semi-structured, qualitative interviews were carried out with nine doctoral students. The theoretical background for analysis of the material is based on the work of Patrick Wilson, with particular focus on the concept of cognitive authority, and on that of Lars Seldén, who has proposed the idea of an information seeking career running parallel to the academic career of the researcher. Results from the interviews indicate that most of the students, in the early stages of their information seeking careers, rely to a great extent on supervisors and more experienced colleagues when identifying material needed for the research project. In a situation where information of potential relevance is abundant and where experience and focus are not yet fully developed, senior researchers function as cognitive authorities and as guides to other cognitive authorities.
Aspergers, andar och böner till Gud : En fallstudie om Aspergers syndrom, religion och andlighet
This case study examined what impact the neurological disorder Asperger?s syndrome has on the line of reasoning about religion and spirituality. Also, the question of whether the four informants showed any tendency to use the cognitive tools calledtheory of mind (ToM), existential theory of mind (EToM) and hypersensitive agency detection device (HADD) or not was put forth. From the interviews five themes were extracted: a stereoscopical view upon the world, thoughts on physical causality, prayer used as one-way communication, spiritual agency and intentionality, as well as existential and social questions. These themes were subsequently matched with theories on ToM, EToM and HADD.
Framtagning av beräkningshjälpmedel för tvärkraftbelastade förband med förbindare av metall.
The governing set of regulations for structural engineering in Sweden used to be Boverket, BKR. However in the beginning of the 21st century a changeover to new regulations, the Eurocodes, started.The transition was completed in year 2011 when the Eurocodes became the mandatory design work policy for all countries within the European Union. The Eurocodes were implemented to simplify and remove potential barriers to trade that may exist when countries have different design rules. Since the changeover it has been important for all construction companies to update their knowledge base and their design software.When comparing the two calculation processes they seem similar, but there are a couple of differences worth noting. With the new regulations, engineers will find that the process when designing joints in timber structures has changed. What used to be a fairly easy and straight forward calculation procedure has now become tedious and time consuming.The objective of this degree project is to present a product, a dimensioning tool that will help structural engineers when computing lateral load carrying joints in timber structures.The degree project is made up of two parts where the first part is the written report describing the background and theory behind load carrying computations. The second part of the project is the actual dimensioning tool which includes several worksheets in Microsoft Excel. The program treats single and double shear connections of the following:Nail jointsScrew jointsSteel plates (thick and thin types) The user can edit the following parameters:Type of plate/ number of shearsStrength class of timber membersMember and plate sizeType of fastenerDiameter of fastenerLength of fastenerYield moment of fastenerkmod and partial factors for design load carrying capacityThe dimensioning tool was created and developed in collaboration with structural engineers at the company Byggteknik AB.
Omvårdnad av den geriatriska hunden
Due to progresses constantly being made in veterinary medicine combined with increasing knowledge in pet owners, the dogs of today gets older than before. The population of geriatric dogs is there for constantly growing, which makes them an important group of patients on small animal clinics and hospitals.
As dogs age, so do their interior organs. Geriatric dogs are prone to several diseases and in this text the author has decided to focus on three of the most common: Cognitive Dysfunction Syndrome (CDS), cancer and osteoarthritis (AO). All of these illnesses are incurable in dogs, but it is important to remember that they are still treatable.
