Internetbaserade distansutbildningar

In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.

Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

Värdering och jämförelse av kvalitetsfaktorer för lokal kollektivtrafik i Helsingfors och Göteborg

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Leaf area index in Vittelaria Paradoxa parklands in Burkina Faso estimated by light interception and leaf sampling

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

Datorbaserad analys av enzymdesign för Diels-Alder  reaktioner

This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

 Basstation-FUMO 3

Through the ages mankind has developed and tested a cascade of varying weapons ofwar, large and small, and has has striven to push these creations to the limits of theirtime. A grand example of this are the medieval siege engines that have changed shapeseveral times over the centuries. After all this time the eciency of these siege engineswill have reached their peek.

Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter

A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.

Ett kulturcentrum i Ulricehamn?

The aim of this essay is to investigate and evaluate the arguments made by municipal politicians in Ulricehamn, regarding the planned Knowledge and Culture Centre. A part from the search for these arguments, I also investigated the attitudes among politicians regarding municipal culture investments in general. I furthermore investigated whether any national, regional, or local culture-political strategies were important in the local debate. The time frame within which the local political culture debate was investigated was from 1997 until present time 2002. The investigation methods used were partly a study of official documents such as political protocols, two articles from the local newspaper, and a clean copy from a web chat, and partly a qualitative study I sent a question regarding the planned Culture Centre to every political party active in the Ulricehamn municipal assembly.

Prövning av måttet Läpp-till-Lyft (L-t-L) på vuxna utan sväljsvårigheter

Context: Lip-to-Lift (L-t-L) is a bedside-method for measuring oral transit time at swallow. It was designed for a swallowing examination of persons on nursing homes where weight loss was noted in people with average L-t-L-time >5 seconds (Sandin, 2005). The measurement was validated and evaluated by Eriksson, Bremer Zerpe (2008).Objectives: The study objective was to examine L-t-L on a group of young adults without swallowing disorders and as to examine the inter- and intra-judgereliability of the measure.Questions:What is the L-t-L-time for young adults without swallowing disorders?Are there any gender differences regarding L-t-L-time?How high is the inter/intra-judge reliability of L-t-L?Method: Examination of L-t-L-time was carried out on 20 young adults, aged 19-27 years, without swallowing disorders after Sandin?s (2005) instructions. Measurements of 20 swallows per person were made.Results: The average L-t-L-time of young adults without deglutition-difficulties was 1.13 seconds (sd =.14).

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.

Faktaboken i praktiken : hur ett antal barn- och ungdomsbibliotekarier arbetar med faktaböcker i sin lässtimulerande verksamhet

The purpose of this thesis is to study how children's librarians in public libraries use non-fiction books in their work to promote reading. My research questions are: What methods do children's librarians use för promoting non-fiction books? Are there children who can gain more from non-fiction books than other children do? Are there any differences in working with fiction and non-fiction books? To answer these questions I have interwieved five children's librarians about their methods, attitudes and thoughts on non-fiction books.The result shows that all of the librarians use non-fiction when it comes to promotion reading but not to the same extent. Some hardly use it at all, mainly because the schools that they are serving demands fiction books when practicing reading skills. while others use it but in less extent than fiction, as a way of separating the library reading from school work either because they want to keep the experience of reading in the library apart from school work or because they find it more efficient to do so.

Studie av rakriktning : mätningar av tygelkrafter och symmetrier i hästens rörelsemönster

The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.

Navigering, koordinering och översikt

The advantage and the possibility of keeping track of a number of vehicles to make work practice more effective and smooth is today a favorable choice for Visual Units Logistics customers. We?ve been evaluating the software and trying to take it one step further and letting not only the individual user, but maybe, the company as a whole benefit from its advantages. This has been done by using methods like letting ourselves get to know the software, user case studies, workplace studies, interviews and future workshops. This resulted in a prototype introducing a new function designed with all collected data in mind trying to make the software, Visual Units Logistics, even more effective for the every day work practice of the user. A new function to keep track of vehicles outside the main working area at the same time as you still can keep track of the other vehicles in the field..
