Konstruktion av truckmonterad hjulhanterare

GBD-Storage Systems is a company that provides the industries with products for efficient storage.The company produces pallet racks and accessories like cassettes and extending units. The companyhas also supplied tire racks for a number of tire companies. The company's CEO Gunnar Berglund hasfor some time had an idea to improve the working situation of the workers on tire firms by allowingthe wheels to be handled by a counterbalance truck. The current situation poses numerous heavy liftswhen the tires are handled and therefore is hurting the workers.This thesis has been aiming at helping the GBD-Storage Systems by developing a concept of howan accessory to counterbalanced trucks can be designed to cope with the wheels. This concept willthen be produced as prototype by the company.

Läsförmågans faktorer och deras bidrag till läsning : En jämförelse mellan barn med olika nivå av läsförmåga, utifrån The Simple View of Reading

The simple view of reading is a theory in which reading is divided into decoding and linguistic comprehension. The theory has been used to explain and to subgroup reading disabilities. Research has also investigated if additional factors are of relevance to reading. In the present study, decoding was divided into the factors orthographic decoding and phonological decoding, while comprehension was divided into word comprehension and grammatical comprehension. The purpose was to analyze these factors and their contribution to reading ability in children in fourth grade: one group with reading difficulties (n=36) and one group with typical reading ability (n=36).

Fröplacering vid hög såhastighet - Väderstad Rapid jämfört med Amazone Cirrus

In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.

Sociala relations som skapas i Mmorpg-spel.

Background: It is today common for companies to provide some sort of incentive for CEO's and senior management positions to motivate, retain and benefit employees within a company. This is in order to drive the goals of the CEO and management in the direction that is desired by the owner. Currently, the Swedish centre-right government has forbidden the use of such variable pay within state-owned companies. There are two different attitudes to variable pay, one that is in favour and one that rejects it. However most people agree on the fact that a well-functioning incentive scheme can be of great strategic importance for a company.Approach: has variable pay to CEO's had any effect on the company's profitability.Aim: the aim of the study is to compare companies who use variable pay to CEO's with companies that do not in relation to their profitability in terms of profit margins, yearly performance, returns on total capital and returns on equity.Method: the study uses a quantitative approach.

Omkonstruktion av treaxlig plockrobot och dess plockverktyg

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

Phenotyping of Bali cattle and interviewing farmers in Indonesia - a minor field study

Among the Indigenous cattle breeds in Indonesia, the Bali cattle is the most preferred by small farmers. The Bali cattle is a beef breed, and is considered to have several advantageous characteristics and to be well adapted to the country?s harsh environmental tropical conditions with drought and rain. The main aim of this project was to phenotype of Bali cattle from different locations in order to identify and document diversity within the Bali cattle breed based on their observable characteristics, to compare cattle from different areas and production systems to see the effect of management on phenotype. In this study, 107 cows and bulls of the breed Bali cattle, from Kalimantan, Sumatra, Lombok and Bali were phenotyped.

Utvärdering av Capcals förmåga att beräkna framkomlighet

Performance of an intersection affects the total travel time in a traffic network. An intersection with good performance can easily be described by its contribution to lower travel time than in a comparable intersection. The travel time is of importance in the cost calculations when a specific intersection is to be chosen and designed. It is important to be able to make correct and precise performance calculations so that the cost calculations will not be incorrect. For that purpose the software Capcal, which is a traffic model for intersection analysis on performance, is used in Sweden.

Korrelationen mellan fotgängares skador i verkliga olyckor och Euro NCAPs testresultat för fotgängarskydd

The aim of the present study was to estimate the correlation between Euro NCAP pedestrian rating scores and injury outcome in real-life car to pedestrian crashes, with special focus on long-term disability. The study also surveyed most frequently injured body regions and risk differences for specific elements of pedestrians hit by cars. Another aim was to determine whether Brake Assist systems affect the injury outcome in real-life car to pedestrian crashes and to estimate the effect in injury reduction of a high Euro NCAP ranking score combined with Brake Assist.In the current study, the Euro NCAP pedestrian scoring was compared with the real-life outcome in pedestrian crashes that occurred in Sweden 2003-2010. The real-life crash data was obtained from the data acquisition system STRADA, which combines police records and hospital admission data. The medical data consisted of International Statistical Classification of Diseases and Related Health Problems (ICD) diagnoses and Abbreviated Injury Scale (AIS) scoring.

Sverige 2112 : Ett narrativ om hur arkitekturen kan utvecklas om världen går igenom stora förändringar på grund av klimatförändringarna. En linjär och vertikal stad.

Om världen till följd av klimatförändringarna blir mycket varmare kommer förutsättningarna för hur vi planerar städer, infrastruktur och jordbruk helt att vändas upp och ner. De delar av världen som idag står för världens livsmedelsproduktion kommer vid bara några graders förändring bli obrukbara som betes och odlingsmark. Dessa förändringar kan komma att starta konflikter, och stora flyktingströmmar som tillsammans med förändrade klimatzoner helt kommer att rita om världskartan. i Skandinavien är det då troligt att vi behöver bygga samhällen och städer för miljontals nya immigranter, och detta samtidigt som vi befinner oss mitt i den mest fruktbara jordbruksmarken i världen. Om hundra år måste vi dessutom, oavsett detta, dubbla livsmedelsproduktionen globalt sett.Vårt samhälle blir allt mer rörligt och infrastrukturen utvecklas i allt snabbare takt.

Transientanalys för Forsmark block 2 och 3 : Studie av hur val av driftpunkt och pumpreglering påverkar torrkokningsgränsvärdet

The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.

ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

Identifiering och redovisning av immateriella tillgångar vid rörelseförvärv ?En kvantitativ studie om redovisningstransparens och kapitalmarknadens informationsasymmetri

The association between disclosure level and asymmetric information is a matter of importance andconsiderable interest to the financial reporting community. The theory in this area suggests that acommitment by a firm to increased levels of disclosure should lower the information asymmetry thuslowering the cost of equity. This theory may be compelling, but so far the empirical results have beenambiguous. Due to increased globalization the demand for high quality accounting standards has risen. In2005 The International Accounting Standard Board launched the standard named IFRS 3.

Implementation of an FFT algorithm using a soft processor core

This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..
