Today, many discussions are taking place through different platforms concerning the huge problem of ill health within modern society. Ill health tends to affect both children and adults. For the adult sector ill health may lead to doctor?s notification of illness in the short term and on the long term permanent disability benefit. In the mass media there are often articles published that point out the rising number of people with sick pay and people being given permanent disability benefit.

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

Syftet med denna studie var att undersöka handbollstränares kunskap och förståelse för feedback utifrån ett aktörsperspektiv. Urvalet baserades på lokala handbollsklubbar där kravet var att de skulle träna flickor i 16 ? årsåldern. Det skickades ut brev till 16 olika klubbar där en förfrågan gjordes om ett deltagande. Tre stycken handbollstränare som uppmätte urvalet valde att delta i studien och dessa har behandlats med anonymitet under hela processen.

Individens tro på den egna förmågan benämns self-efficacy och är en viktig del vid avgörandet av hur en uppgift ska lösas, samt av hur resultatet blir. När individer presterar spelar feedback en central roll för om det kommer att skapas motivation att uppnå målen eller inte. Ovan nämnda begrepp är även centrala för den kollektiva self-efficacy som är gruppens tro på sin förmåga. Studiens syfte var att undersöka hur en individs self-efficacy påverkas vid ett negativt utfall inom ett prestationsområde. En enkätundersökning med 81 lagidrottsspelare genomfördes i Västmanlands län.

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.

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.

The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..

Syfte och frågeställningarSyftet med uppsatsen var att genom systematisk observation undersöka hur en ungdomsfotbollstränare använder sig av beteenden som är överensstämmande med Enhanced Guided Discovery (EGD) och Teaching Games for Understanding (TGfU) i sin tränarroll under träning. Syftet besvarades med hjälp av följande frågeställningar: Hur ser fördelningen ut för tränaren med instruktionsbeteenden, feedback och frågetekniker? Hur stor del av träningen går åt till aktiviteter i training form respektive playing form?MetodMetoden som användes var en systematisk deltagande observation. Observationen gjordes i realtid och följde en modifierad version av Coach Analysis and Intervention System (CAIS)(Cushion, Harvey, Muir & Nelson 2012, s. 201ff.; Partington & Cushion 2011).

En sammanfattande rapport över de lärdomar vi gjort under bl.a. ett projekt vid Närpolisen i Lund (NÄPO Lund). Rapporten behandlar bl.a. områden som konsult-klient förhållandet, ledarskap, individuell utveckling, grupputveckling och feedback..

What if the emergency response directly knew exactly where to go and what to do if a road accident occured? During the last ten years the number of motorcyclists in Sweden has doubled. Every year, more than 300 riders are seriously injured and over 40 die in road accidents. Being found in time is critical to increase the chance of survival. The goal of this project is to use design methods to find a solution that enables a fast and adequate emergency response for motorcyclists and other unprotected road users..

Syftet med denna uppsats är att undersöka om medelstora och stora företag i olika branscher använder sig av liknande feedbacksystem när feedback ges till ledare.Det som vi kommit fram till efter att ha studerat fyra företag i olika branscher och storlek är att de mätbara värdena som exempelvis produktivitet, gavs som feedback på liknande sätt till ledare. Företagen gav feedback på det som producerades och hur pass väl ledarens grupp uppnått uppsatta mål. Mjuka värden som exempelvis ledarens ledaregenskaper, gavs från ledarens ledare vilket är det vanligaste i företag. Ett av de intervjuade företagen bedrev dock även feedback från underställda genom frågeformulär som sedan sammansattes i en modell som gav ett ledarindex. Ledaren kunde därmed se vad medarbetarna tycker om dennes ledarstil.

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.
