3D-bootstrap - Konfidensintervall för guldfyndigheter
This paper deals with evaluating 3D-bootstrap for the mining company New Boliden in an attempt to revise their current method of calculating average gold riches in different areas. The purpose is to find one-sided 3D-bootstrap confidence bound of the average gold riches. There lacks well-defined theory behind using 3D-bootstrap, in this paper the variogram is used as an estimate of dependencies between the observations, and the block length is chosen to be higher than this estimate. In aid of this, a simulated data material is conducted to check the validity of 3D-bootstrap in a controlled area where the theoretical value is known. The results are inconclusive, and further studies are needed..

Brudkronor i Tjust : koncept, symbol, funktion
This essay comprises a study of the bridal crowns of Tjust, with respect to their national history, concept and aspect of mythological symbol. The tradition of bearing the parochial bridal crown is closely associated with religious medieval politics, and has also come to include elements of superstition and folklore. Attention is paid to these aspects dealing with the position of the bridal crown within current forms of tradition and culture and the impact on brides of this day and age. As the tradition of Church-owned bridal crowns is intrinsic to this country, and especially in the area of which Tjust is a part, possible solutions to the continued tradition are investigated..
Kan ett konkret arbetssätt påverka lusten till matematik?
The purpose behind this work was to investigate whether I could from a practical approach to create desire for mathematics among students in primary schools. I wanted also to find out how students feel about their current mathematics teaching. By introducing an equation game, and interviewing students to find out their perception of their mathematics teaching, I was able to answer my questions. What I came to was that through a practical and laboratory work, I could create an enjoyable educational opportunity in mathematics. Then during the interviews I also learned that students had not a pre-determined negative attitude towards mathematics.
SKOTTSTÄLLNING AV ÖVNINGSVAPEN TILL GRANATGEVÄR CARL GUSTAF
This 15 point thesis is carried out at Saab Dynamics AB in Karlskoga. The company produces defense material aimed at the Swedish market and for export.The task was to make a survey of the current zeroing procedure for Sub Caliber Adapter for 84 mm recoilless rifle Carl Gustaf, and to examine the accuracy of the tools used today for zeroing.Measurements performed show that some of the tools has good accuracy for zeroing of Sub Caliber Adapter 20 mm withe other tools are not so good. The accuracy for zeroing of Sub Caliber Adapter 7.62 mm is not sufficientWith a suitable design it is possible to produce tools with good accuracy for zeroing of Sub Caliber Adapters..
Aktivitens betydelse för åldersrelaterad kognitiv försämring
The current paper compares the relations between different measures of activity and some common neuropsychological tests. One-hundred and fifty five healthy elderly, aged 55 - 85, living in Sweden were included. Gender-specific patterns were found for both activities and correlations between activities and cognitive measures. The main findings suggest that activities are associated with cognitive speed in men, whereas, for women, active and passive activities correlate, positively and negatively accordingly, with education. In comparison, complex models of activity outperform simpler ones and theory-driven measures just barely outperform intuitive models..
En nutida analys av reseguidehemsidor
In this research our goal is to conclude the aspects of interactivity which can prove to be important during the creation of a website. The focus in this essay is websites functioning as travelingguides, because we live in a time of traveling, experiance and learning. How can an analyzing method of websites be shaped? What can an analyze of interactivity on current travelingguides provide for recommendations by the creation of interactive travelingguides? The analyzingmethod is based on three shapingmethods and a poll that was answered by both national and international people. The analyze gave us quite clear results, if you follow the basics of Use Case, Personas, Usability and design, the website will have a bigger chanse of attracting people than if it doesn't..
Delta X : Utveckling av värmeväxlare
Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..

Processer och metoder som möjliggör för en effektiv produktframtagning
The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they?re facing and offers a great potential to create significant competitive advantages.
