In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

This Master of Science thesis was a part of Pharmadule Emtungas project to construct a mobile automated cell for welding of carbon steel pipe (Heating, Ventilation and Sanitation). Pharmadule Emtunga is using a modular building concept for building pharmaceutical factories. The modules contain these pipes. The goal of the thesis was to present concepts for technical solutions regarding welding methods and fixtures for the cell. Conceptual models for the cell were made with aid of CAD software.

A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.

Problems arise when the number of products in stock does not correspond with the number of products the information system says the company has in stock. (Sharda & Agrawal, 2012) In order to change that, major changes has to be made when it comes to making continuous improvements and to raise their standards regarding product availability and record inaccuracy (Wild, 2004).The purpose of this study is therefore designed to identify factors affecting the balance differences and what impact it has on the efficiency of material flow. The demarcation of the work is that Atlas Copco has begun working with Lean and it will not be investigated nor the relationship between balance differences and Lean. The study was based on answering the following questions: What influencing factors can be identified for balance differences? What factors are relevant to the efficiency of material flow? What kind of impact the balance differences has on these factors?In order to answer the purpose and issues, a theoretical framework has been developed with help of literature studies and an analytical model.

This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.

The global spread of the Internet has enabled busniesses and consumers in all industries to be better informed. Consequently, the buying process has appeared to become different from what tratditional models implies. As the buying behaviour among customers is evolving, selling companies are responding to this change. This thesis evolves around the consequences that the developing relationship between buyer and seller in business-to-business companies has led to. The topic in focus is the buzzword and phenomena "content marketing" with its marketing and selling strategy.

SammanfattningDet här arbetet är en litteraturstudie. Arbetet tar upp litteratur om kommunikation i vården främst från humansidan, men även en del veterinärlitteratur. Arbetet tar upp grunden för kommunikation och olika kommunikationsmodeller. Vidare tas sjuksköterskans roll upp och hur den kan påverka relationen till patienten genom professionalism, empati, människosyn och medmänsklighet. Det handlar även om vad litteraturen säger om effekten av behandling som ett resultat av kommunikation samt hur man kan mäta effekten av behandling.

Uppsatsen behandlar ämnet användbarhet i mobila webblösningar med inriktning mot tidningsbranschen. En jämförelse mellan de två aktuella designfilosofier, dedikerad design och responsiv design, för den mobila webben har utförts genom att fokusera på användbarhet, där centrala begrepp studerats. Begreppen är som följer: Usefulness, Efficiency, Effectivness, Learnability, Satisfaction. Mixade metoder i form av enkätstudier, heuristiska tester, användartester, intervjuer och prestandatester har utförts för att samla in empiriskt material för analys och för att sedan ge en slutsats angående vilken av de två designfilosofierna som tenderar att ge hög användbarhet i system som exempelvis tidningssajter i mobilen.De mest intressanta resultaten var att, sett ur användbarhetssynpunkt, var båda designfilosofier likvärdiga, majoriteten svarade att de testade sajterna fungerade på liknande sätt. Alla uppgifter kunde utföras utan större problem på båda sajterna vilket uppfyller kravet för effectivness.

This work is an experimental study where knock sensor placements are investigated using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control, the engine is running while the knock sensors with advanced measurement equipment is connected to the engine. Evaluation of signals from the knock sensors are made in the computer program Matlab. The program is producing a seriesof plots, from these plots it is visually possible to draw conclusions and find connections.

The objective of this study is to examine how Lean can make the utilization of inventory more effective and, from a Lean perspective, examine how the value-adding activities related to inventory can increase. To examine this, a case study was perfomed at Svenska Fönster. The conclusions of this study are that Lean can advantageously be applied on inventory to increase the efficiency. .

The aim in this project was to spread play in the city and acrossgenerations. My way of approaching this challenge was to explore theborderland between playground equipment and street furniture. Thisopened up many possibilities to afford play in places where playgroundequipment often is excluded.The goal was to create one, or more, furniture with play value. The targetgroup was all vivasious people spending time in the public outdoorspace. Through user studies, a lot of serious playing and a lot of testing,the project resulted in a bench called Rollin´.

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

LEXION is the name of the largest series of combines made by the CLAAS factory in Germany. LEXION was introduced on the Swedish market 1996 and was for sale in Sweden from 1997. LMB have sold over 400 LEXION-combines in Sweden. In cooperation with the Swedish general agency we decided to make a market research on the Swedish LEXION-market. The questionnaire was supposed to give answers about capacity and technical equipment. Before I made the questionnaire I studied manuals and combines. I got 81 answers of about 325 questionnaires. That makes 25 % reply frequency.

The main purpose of this study is to examine differences and similarities concerning teamwork and interactive skills among preschool children while they interact with an Ipad respective a number of selected traditional artifacts. The traditional artifacts chosen for this study are small Lego blocks, JovoToys (click and construct system) and large puzzles. The study takes its starting point on the basis of both a social- and a learning perspective when different groups of preschool children in the ages from three to five years interact in fellowship groups with respective artifact. Primarily the main focus is to examine differences and similarities that appear from without the social perspective.The overall objective is to identify what eventual differences and similarities can be found purposely on both what is happening in the social interaction between the preschool children themselves but also what is taking place in the interaction between the children and each artifact. This study will also via theoretical frameworks create an understanding why eventual differences and similarities exist.The results are based on both a literature review and a field study.
