Förväntningar på Framtida Mobila Tjänster
Today?s society is very focused around technology and something that is very popular is the usage of mobile devices such as Smartphones or Tablet computers. One of the reasons why these devices are so popular, is because of the large amounts of services or ?apps? that they can provide for the user. They can do a lot of things that makes everyday living easier for the users.The focus of this study is to find out what kinds of mobile services the users of these devices are expecting and/or wishes to see in the future and what is required to be able to develop and use these services in a good way.We started of the study by searching for earlier studies on the same or similar subjects.
Meeting, greeting & seating : a design proposal for Magomeni garden, Dar es Salaam, Tanzania
More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations.
Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist.
There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.
Mätning av abrasivflöde för vattenskärningsmaskiner
The content of the following report is the summarized result of three students
thesis at Blekinge Institute of Technology in co-operation with Water Jet
Sweden AB.
This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.
Produktionsvåtmarker mot övergödning
In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.
Legionella i tappvattensystem. Förekomst och förebyggnade-en redogörelse.
Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.
Miljökonsekvenser av dagvattendamm i Skebäck, Örebro : en fallstudie hur miljöpåverkan av en dagvattendamm intill ett Natura 2000-område kan bedömas
Stormwater is surface runoff water that originates from precipitation or snowmelt and that on hardened surfaces prevents to infiltrate the ground. In city areas stormwater can consists of major amounts pollutants and when reaching a lake or watercourse it can cause damages on vegetation and animals. Therefore it is important to treat polluted stormwater before it reaches the recipient.
The municipality of Örebro have since the 90ies an extensive work with treatment of stormwater in sedimentation ponds. A new stormwater treatment project is planned in an industrial estate in Skebäck, Örebro.
Selånger deltapark : Sundsvalls nya stadspark - en vision
The river Selångersån runs through thenorthern Swedish city of Sundsvall, splittingthe city in two as it winds through thevalley between Södra- and Norra Stadsbergetand out into the Baltic Sea.The river is a national interest of nature conservationbut at the same time in the middleof an urban development string for the city,creating a complex situation of developmentcontra conservation of natural environment.This project attempts to create a strategy oflandscape urbanism for the area surroundingSelånger Bay, four kilometers upstreamalong Selångersån. A sensitive wetland, todayrather forgotten but with great potentialfor introducing wild nature as an active partof the city. Or rather, initiating a processwhere the built environment can infiltrateand enrich the natural environment gradually.A city park in this location to initiate thisprocess could be a joint project of the city?sresidents with the scope to become a projectin constant development.The idea of the project is to offer a large ecologicalpark and meeting place near the citycenter. This will be achieved by clarifyingthe activities and values that already existin the park, such as the largest living deltai the region, football fields and a medievalchurch ruin, and by creating new paths.
Att drabbas av och leva med stroke : en studie av självbiografier
Stroke is a widespread disease in Sweden. Nurses play a central part for those who suffer from a stroke irrespective of where in the care chain they meet. To be able to meet the patients? need of care the nurse must understand his/her lifeworld. Each and every patient is unique and the experience of being struck by a stroke depends on personality and life situation.
Flexibel isolering av fönster för att minska energiförluster
The first part of this essay is about a single-family house that we have planned and projected. Thesecond part is a deeper study in ways to further insulate windows when they are not in use.In the first part the building?s design and its most important construction elements are described.The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity)are reported so that one can in principle start construction of the house. In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south.
Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?
In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.
Living the brand : En varumärkesbyggande företagskulturstrategi
Denna uppsats behandlar ledarskap och organisationsförändring. I rapporten undersöks hur fyra chefer har handskats med de svårigheter och utmaningar som uppstått då organisationen de verkar i ska driva igenom förändringsprojekt. De undersökta organisationerna är Försvarsmakten Visby garnison, Scania AB Falun, Apoteket AB och Nacka kommun. I de två förstnämnda består förändringsprocessen av mer eller mindre total avveckling och i de andra två rör det sig om omfattande förändringar i struktur eller arbetssätt. Undersökningen är baserad på djupintervjuer med dessa chefer och svaren har analyserats utifrån existerande modeller för förändring.
Praktisk Fysik : Laborationernas och demonstrationernas vara eller inte vara.
Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..
Att styra bilanvändning mot en hållbar utveckling. Om geografiska livsvillkor kontra offentliga ingrepps betydelse för bilanvändning.
Car usage is determined by several facts, e.g. living conditions determined by geographical matters. There is a political will to control car usage with different kinds of incentives since car usage generates environmental problems. This essay analyses the differences between car usage in urban areas as opposed to thinly populated areas in Sweden and their significance on governmental incentives. By using statistics differences in car ownership during ten years between thinly populated areas, areas in the countryside and urban areas is studied.
Hiv - En förstummande sjukdom? : socionomstudenters och socialsekreterares attityder till hiv-positiva
The aim of this study is to examine social workers' and social work students' attitudes towards people living with hiv in Sweden. I will also examine if there is a connection between knowledge and attitudes. The questions at issue are how social workers' and social work students' attitudes can assume to influence on their professional practice and what causes can affect their attitudes towards people living with hiv. The study is based on a qualitative method. The methods have been: conversational interviews with five social workers, who work with family issues and integration, and a focused group interview with four social work students.
Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd
The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth.
Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.
