In today's society it is becoming more and more important with direct marketing. Some of the direct marketing is done through e-mail, in which companies see an easy way to advertise himself. I did this thesis work at WebDoc Systems. They have a product that creates web documents directly in your browser, also called CMS. The CMS has a module for sending mass e-mail, but this module does not function properly and WebDoc Systems customers are dissatisfied with that part of the product.

Skiascopy is used to objectively determine the refractive power of the eye. Except for a Swedish study in 2007, where 93 horses of different breeds and ages were examined with respect to their refractive status, most studies on equine refraction were published about one century ago or more. The objective of this study is to examine the refractive status of healthy warm-blooded trotting horses. Skiascopy was performed in 117 horses in total, aged 3 days to approximately 22 years old. In a pilot study, it was determined whether young horses were able to accommodate or not during skiascopy. The horses in the pilot study were all younger than 14 months. In foals younger than 1,5 months we saw a significant difference in the skiascopy result in the right eyes before and after topical atropine was instilled, but not in the left eye.

IKEA HaparandaTornio employ some two-hundred people in its furniture retail store.Keeping track of staff statistics and employee information has previously been achievedthrough the use of a basic Microsoft Office Excel spreadsheet. The store?s human resourcesdepartment requested an upgrade to this system with the hope of speeding up andsimplifying the administrative process, as well as to make it easier to monitor HR-relatedtarget statistics. The following report documents the development process of that upgrade ascarried out by the author. The project draws on research in usability design and cognitivepsychology to develop a user-friendly interface.

AbstractThe purpose of this investigation was to understand how teachers/pedagogues nowadays work with mathematics in school. In what way can they pin point the difficulties a pupil with another language might have with mathematics.I started the process of this investigation by reading litterature on the subject. Then I did interviews with several teachers and pedagogues teaching in different schools with children at different ages.The results found in my investegation pointed to a lack of practical work with mathematics especially in classroom and revealed from the teachers a strong desire to work with mathematics in different ways.?Talking maths? with pupils in class will help them understand the subject better. Several teachers are of the opinion that the pupils will reach the goals in school with this method.The teachers are also aware of the importance of having practical mathematics.

Symboler har alltid varit en viktig del av matematik, därför är det inte konstigt att kunskaperom symbolspråket behövs för att uppnå en full förståelse av ämnet. Den här studiensyftar därför på att utreda användningen av det symboliska språket i den svenska gymnasialaundervisningen ur ett språkvetenskapligt perspektiv. Empirin till det här arbetetbestår av 52 elevlösningar till ett test i matematik samt transkribering av en parintervju.Det insamlade materialet har analyserats utifrån teorier om den metalingvistiska medvetenhetensamt symbolernas semiotiska och epistemologiska funktioner. Det matematiskasymbolspråkets roll i styrdokumenten har också belysts i det här arbetet. Från elevernasfel i testet var det möjligt att åskådliggöra vikten av den metalingvistiska medvetenhetenoch den semiotiska medlingen i algebrainlärningen.

The purpose of this study was to explore students' and teachers' experiences of the new pedagogical teaching tool, interactive whiteboard, which have gained increased popularity and wide spread usage in the classrooms. An observation during a mathematical lecture was conducted as a pilot study prior to the main research method of phenomenology; based on students? self-descriptions and interviews with two teachers, this methodological approach was used to investigate the subject matter. The interpretation, comparison and analysis of the results surrounding this new teaching method is explained by two theories, constructivism and socio-cultural perspective. The information shared by the students and teachers have been broken down into four categories: enjoyment & interest, practical, insight and no different.

To be able to protect themselves from credit risk, the banks must constantly check the performance of  the companies they have lent money to. There are many mathematical models for predicting financial distress. These models use accounting-based ratios, which often are historical and not representative for the present situation. This study describes how the banks do in practice to find signals of insolvency in time and the variables they are observing for doing that.In addition to financial reports which the company sends in to the bank at least once a year, also the relationship between them and information from different information  agencies are of great importance to track  signals of insolvency. Poor profitability is the primary cause of insolvency.

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database.

En studie i om handdockan kan stärka den matematiska förståelsen och hur pedagoger skulle kunna använda den som redskap. Geometriska former och rumsuppfattning har stor betydelse i barns verklighetsuppfattning och lärande i matematik. Vi valde att fokusera på en geometrisk form, rektangeln. Vårt arbetssätt har bestått av intervjuer, observationer och dokumentation av genomförandet. Studien genomfördes i två helt skilda förskolor men har gjorts på liknande sätt och med samma frågeställningar.

Målet med denna studie är att undersöka hur matematiskt särbegåvade elever upplever sin matematikundervisning i skolan. För att uppnå studiens syfte har ett antal preciserade frågeställningar utarbetats, och som också har legat till grund för studiens empiriska undersökning. Frågeställningarna har hanterat såväl elevernas som deras föräldrars subjektiva upplevelser av barnens matematiska begåvning, hur den matematiska undervisningen för dessa barn ser ut samt hur föräldrarna upplever att skolan stimulerar och uppmuntrar särbegåvade barn. Examensarbetets metodologiska tillvägagångssätt har baserats på en kvalitativ undersökning där materialet har baserat på sex elever med matematisk särbegåvning och deras lärare. Dessa har intervjuats.

Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

According to some researchers, dyscalculia is at least as prevalent as dyslexia. Somewhere between 3.6-6 % of all pupils have specific mathematics difficulties named dyslexia. If this be true, it should present the most complex special education predicament by far in schools today. Despite the statistics, dyscalculia is still a rather unknown concept.The cause of dyscalculia is not yet fully analyzed. There are several theories and many researchers see similarities between dyscalculia and the special educational problem of reading and writing, dyslexia.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

Syftet med denna undersökning har varit att studera gymnasieelevers förståelse för funktionsbegreppet.Den teoretiska utgångspunkten har varit att studera elevernas förmåga att växla mellanolika representationsformer och studera deras förståelse för relationen mellan de olika representationerna.Elevernas förmåga att resonera har också varit en väsentlig del och därför har forskningenkring matematiskt resonemang också varit en viktig del i arbetet. För att nå ett resultat har treklasser på gymnasiet fått skriva ett test konstruerat för att svara mot uppsatsens syfte. Utövertestet intervjuades tre av eleverna för att det skulle finnas möjlighet att fånga elevernas förmågaatt resonera. Resultatet kom att visa att vissa elever har svårt att utföra växlingar mellan vissaolika representationer, men mellan andra är det betydligt enklare. Det framkom att eleverna varskolade i ett algoritmiskt tänkande, och att eleverna hade svårt att resonera fritt och kreativt kringfunktionsbegreppet, samt att eleverna hade svårt att skilja de närliggande begreppen ekvation ochfunktion..

Det huvudsakliga syftet med denna rapport är att genomföra och testa en implementationsteknik för ragdolls ämnade användas i spelsammanhang. Implementationen sker genom en kombination av en verletimplementering tillsammans med en fördefinierad bone-hierarki i meshen som skall användas. Verletimplementeringen programmerades som en grund till en enklare fysikmotor och parsningen och struktureringen av meshen sköttes parallellt utanför fysikmotorn. Rotationsmatriser för samtliga större kroppsdelar, såsom över- och underarmar, överkropp, huvud etc. beräknas sedan i fysikmotorn och används för att vrida mesh-kroppen rätt.
