ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler
In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.
Amfibier i nyanlagda våtmarker : En fältstudie i Laholms jordbrukslandskap
Many species of amphibians are threatened both in Sweden and globally. The causes are many and a main factor is habitat alterations which often results in populations being isolated. Changes in the agricultural landscape have among other things resulted in small water bodies being filled and dried out and that has severely affected the Swedish amphibians. Swedish amphibians are depended upon small water bodies for their reproduction. Wetlands have been constructed to reduce the impacts of the eutrophication in the Laholm bay.
Säkerhetsstandard för ett mjukvarubaserat säkerhetselement
Researchers today anticipate that in the near future, the majority of the owners of a smartphone will use it as a wallet, i.e. for contactless payment. The technology that enables contactless payment today is ?Near Field Communication? (NFC), which is increasingly embedded in smartphones. Applications like mobile payment between a phone and a terminal use NFC.

Digital delaktighet i Sverige : Om att inkludera alla i framtidens samhälle
Almost all Swedes today have access to the Internet, if not through the home then via the library or work. Despite this, around 20% of the population stand outside the information society in that they lack in knowledge, assistive usability tools or positive attitude towards technology and its influence on society. The main factors influencing the digital divide in today's society are age, disability and education, while the main reason for staying outside seems to be disinterest.The question about digital inclusion is important as we now stand on the breaking-point between a society where the industry has had a prominent position for private as well as national economy and a digital society where access to the Internet is no longer about prestige, but where significant differences between users' knowledge levels can create a power gap. Gaps in access and use not only reflects already existing socio-economic conditions, but can also maintain and enhance these.It is crucial for the future expansion of Internet usage how today's non-users feel about becoming users. To understand what underlies the motivations not to use computers is one of the keys to get non-users to embrace becoming users.
Konsolidering av v?vsp?nda papperstapeter: analys och metodutveckling
Printed and painted wallpaper on a weaved fabric backing was a common way to decorate homes in Sweden during the eighteenth and nineteenth centuries. Not much is written about the craftsmanship in relation to the hanging of these wallpapers and even less about the conservation of the objects. Even so, many wall segments remain in situ and in museums and are more often than not in dire need of conservation such as deacidification and consolidation. These are composite objects, consisting of cellulose materials with different properties along with adhesives and paints. Analysis of the materials is required to ensure safe handling and choice of conservation materials, and to establish a treatment plan which will be executed in several steps.
This thesis aims to identify these steps and develop a method for conserving the wall segments with suitable materials, preferably without altering the source material to any significant degree.
Kväve i Östra Mälaren : hur kunskap förvaltas och används i tillståndsprocesser
The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.
Att väcka tankar och känslor om jämställdhet. En studie om enhetschefers styrning av närbyråkraters jämställdhetsarbete.
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.
Uttorkning av lera : Orsaker och följder
When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees. The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences. The thesis was executed as a combination between literature- and casestudie. After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water.

Känsla för vatten : rekreation i innerstad med fokus på bad
This graduation thesis is about baths and beach like places in city centers. It focuses on recreation and the creation and development of public, social spaces in the city containing water as a visual and useable element.
The thesis is divided into three parts; background, inspiration and application.
The background examines four factors which we consider important for the occurrence of inner city baths; water, the history of bathing, inner city recreation and social life in public places. A discussion of the (future) importance of inner city baths and beach like places' is then presented.
The inspirational part is divided into examples of existing places and examples of types of places. The first is used in an attempt to examine the function and importance of inner city baths and beach like places as well as the opportunities and challenges associated with them. The latter contains a presentation of six categories developed by us to facilitate the planning of inner city baths and beach like places.
Skydd mot yterosion i slänter av finmorän
Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

Det moderna biblioteket inätverkssamhället : En studie över kulturpolitikers och bibliotekariers åsikter om bibliotekens användande av sociala medier
?The modern library in the network society?A study of cultural politicians and librarians opinions about libraries' use of social mediaSocial media is becoming more and more interacted in our daily lives and Carlsson (2013) argues that today's libraries have undergone major challenges in the digital information technology's entry in the library arena. The new technology has led to sum up in one question: how a library should relate to the digital information technology, the issue has applied in particular the social communications media, such as Facebook, Twitter and more. The purpose of this paper is to examine the culture of politicians and librarians 'perceptions of public libraries' use of social media linked to the libraries and their democracy promotion efforts. This is analyzed from Castells theories about the network society and the digital divide.In summary, the study concluded that the majority of the culture politicians and librarians believe that social media is a part of the future of the library.
