Metodbeskrivning för identifikation av råvaror med TLC
In some cases there are no methods to identify raw material which are included in dietary supplements such as tablets. The identification can be done with TLC. A general method description was developed using the raw material gotukola and appel cider vinegar. This includes processing to achieve higher concentration of the active ingredient if needed; evaluation of solubility agents to dissolve the active substance; evaluation of mobile and stationary phase and visualization of the stationary phase. The report also includes an evaluation of stationary plates..
Utvärdering av sökmaskiner - en textanalys kring utvärderingar av sökmaskiner på Webben
The purpose of this thesis is to analyse studies that evaluate Web search engines. This is done in four categories; the researchers? purpose, the evaluation measurements, the relevance, and the time aspect. Our method is based on a text analysis in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines.
En SOA utvärderingsmall med fokus på integration, arkitektur och tjänster : Ett praktikfall på Logica
Today, there are no standardized ways to characterize SOA, many are talking about SOA and many say they are using SOA. One way that we have chosen to characterize this phenomenon is through an evaluation that will indicate whether SOA have been used in the development. Basedon a Service Oriented Architecture literature study, we have created an evaluation pattern resulting SOA principles of integration, architecture and services. This evaluation was applied to Logica's own integration system AgrCom through an empirical study to result in a response indicating whether AgrCom is SOA based. The results of the evaluation show that AgrCom is part of an SOA solution but not an SOA as a whole concept.
Vad är kvalitet i ledarskap? : Teorier, modeller och verkligheten
In this qualitative study the authors explores, by studying several quality-development models what quality in leadership is. The models are: Total Quality Management; SIQ?s model for customer-oriented organizational development; the EFQM excellence model; the ISO 9000:2000 standard; and Six Sigma. These models will be compared from Deming?s list for upper management; the Situational Leadership Theory; and the Contingency Theory.
Ergo Mopp : Från koncept till produkt
This thesis describes the work process and the results for the development of a newkind of ergonomic cleaning mop, ranging from basic concept to a virtually productionready digital prototype. The project was made in cooperation with, Ömer Altun, whowas also the project supervisor, and whose plan it is to launch this new product onthe market in a foreseeable future. The mop is meant to be used by both professionalcleaning staff and ordinary home users. What makes this product unique is that it hasa movable center piece that simplifies the cleaning under low furniture.The work began with the establishment of a product requirements specification andlater a study of similar products and existing functional models was conducted. Afterthese surveys the work began with refining the existing concepts in order to makethem more complete.
Pricing Credit Default Index Swaptions A numerical evaluation of pricing models
This study examines the background and nature of the credit default index swaption (CDIS) and presentsrelevant methods for modelling credit risk. A CDIS is a credit derivative contract that gives the buyerright to enter into a credit default index swap (CDS index) contract at a given point in time. ACDS index, in turn, is a multi-name credit default swap (CDS). Within the eld of research, thisthesis identi es the CDIS pricing models presented by Jackson (2005), Rutkowski & Armstrong (2009)and Morini & Brigo (2011) as the most recognized and developed. These models are evaluated byreconstruction in a numerical software environment.
Inclusive business and shared values : case study of Stora Enso in Lao PDR
Businesses role in society is changing. Corporations are expected to take responsibility, not only for their traditional business conduct, but also for social and political issues. A rise in globalization and international trade has led to an increased interest in the concept of CSR. Accordingly, stakeholders are expecting multinational companies to be accountable for existing issues in developing countries. New business models are needed to meet increased expectations of responsibility and shared value creation.
Based on an understanding of the need for new business models a multinational corporation is studied in a local context, where a radically new way of doing business is developed.
MIMO kanalmodeler
The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.
Kommunfullmäktigeledamöters sociala representation -en fallstudie i tre svenska kommuner av kön, ålder och etnicitet
The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.
Integration av simuleringsmodeller för bränslesystemet i JAS 39 Gripen
In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

This is a thesis report from SLU in Skinnskatteberg, the Swedish university of agricultural sciences. This study is an evaluation of a course in attitudes and behavior for participants of the ETT- project led by Skogforsk, the forestry research institute of Sweden. They do research for the benefit of Swedish forestry. The ETT-project is a project where there are both 74 tons ST-trucks and 90 tons ETT-trucks in test on the public roads. This study is concentrated on the ST-trucks and their drivers, company owners and logistics managers.
The evaluation is done by interviews with the various participants.
Klimatpåverkan vid vägbyggnad -beroende av vald konstruktion
It?s a fact that the climate is affected by the vehicle that runs on the worlds roads. But theconstruction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish roadadministration have opposite views of how the construction of roads should be carried thru. It?sthe difference between those two construction methods that is the base in our thesis.The amount of energy use or the emissions are not analyzed for neither the Swedish roadadministrations nor Svevias construction models.
Utvärdering av vibrationer inom vattenkrafts normer
The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.
Informationskompetens - färdighet eller insikt? En jämförelse mellan två modeller över begreppet informationskompetens
This Master's thesis in library and information science aims to shed light on the concept of information literacy in higher education, particularly as manifested in two dissertations on the subject. Two models of information literacy are compared: Christina Doyle's list of ten attributes for students to master and Christine Bruce's seven conceptions of information literacy. The cognitive-behaviourist tradition in Doyle's study and the alternative, phenomenographic approach in Bruce's research are compared and commented. The taxonomies and internal relationship between separate components in the two models are investigated, as well as the ways the models relate to each other. The respective views of knowledge and learning are described.
