Training techniques used in training horses (Equus caballus) : with a focus on positive reinforcement
Instrumental conditioning, the use of reinforcement and punishment, is used when training horses and these procedures may have different consequences regarding animal welfare. The aim of this study was to investigate what kind of reinforcers that are used in training horses and when these reinforcers are used. This study has its focus on positive reinforcement and its advantages and disadvantages. Interviews of five A-level and B -level equestrian coaches about their training methods were conducted to complement the literature search and give a greater understanding to why certain methods are used or not in training horses. The results show that negative reinforcement seems to be the foundation of training horses whereas positive reinforcement is used but not to the same extent.
Rullarmering - Ett rationellt sätt att armera
This is a degree project performed at Halmstad University in Sweden on the subject carpet ofreinforcement. This project is developed in association with Celsa Steel Service in Halmstad.The purpose of this report is to investigate how much time that can be saved if carpet ofreinforcement is used instead of the traditional way to work with reinforcement and seewhat kind of parameters that is important between the choices. We are also going to seehow this product affects the situation for reinforcement workers from an ergonomic point ofview.Carpet of reinforcement is made by straight reinforcement?s bars that are welded togetherwith steel bands. These rolls are made at a factory with a machine that welds together thebars in determined centre distance, with desired dimensions after the constructionengineers? blueprints.
Stålfiberarmerad betong för platta på mark : -En kostnads- och sprickbreddsanalys
AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the conventional reinforcement. Replacing conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.
Q-Learning: Ett sätt att lära agenter att spela fotboll
Den artificiella intelligensen i spel brukar ofta använda sig utav regelbaserade tekniker för dess beteende. Detta har gjort att de artificiella agenterna blivit förutsägbara, vilket är väldigt tydligt för sportspel. Det här arbetet har utvärderat ifall inlärningstekniken Q-learning är bättre på att spela fotboll än en regelbaserade tekniken tillståndsmaskin. För att utvärdera detta har en förenklad fotbollssimulering skapats. Där de båda lagen har använts sig av varsin teknik.
Jämförelse av träningsmetod i olika hundsportsgrenar
Dogs have been held as pets for thousands of years. Dogs held today usually get some sort of training some time during their life. You can train dogs for many different reasons such as general obedience or you can train them for competition. When training a dog every behaviour is followed by a consequence. These consequences are positive reinforcement, positive punishment, negative punishment and negative reinforcement.
Inlärning i Emotional Behavior Networks : Online Unsupervised Reinforcement Learning i kontinuerliga domäner
The largest project at the AICG lab at Linköping University, Cognitive models for virtual characters, focuses on creating an agent architecture for intelligent, virtual characters. The goal is to create an agent that acts naturally and gives a realistic user experience. The purpose of this thesis is to develop and implement an appropriate learning model that fits the existing agent architecture using an agile project methodology. The model developed can be seen as an online unsupervised Reinforcement Learning model that enhances experiences through reward. The model is based on Maes model where new effects are created depending on whether the agent is fulfilling its goals or not.The model we have developed is based on constant monitoring of the system.
Tillsyn av djur på bete : betydelsen av lockgiva och regelbundna tider
During natural conditions cattle live in large herds, which are divided into subgroups of 10-15 animals. Humans have held cattle for over 9000 years. Today we mostly have cows for milk and meat production during more or less intensive forms. Most of the Swedish cattle have the opportunity to graze during the summer time. This partly arises from the Swedish Animal Protection law which stipulates that cattle must have the option to be outside and graze, also partly because it makes it easier for the farmer.
Att arbeta laborativt : Ett arbete om laborativt material riktat till addition
Abstract The purpose of this degree project is to examine what impact working with physical objects has on children?s learning process concerning addition. We want to explore what addition strategies can be exercised using the game ?Twice as much?. We have observed children in school year 1.
Komfortsanalys med hänsyn till vibrationer orsakade av människoaktiviteter. : Ett modernt dimensioneringsproblem för huskonstruktörer
Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.
Ergonomi vid armeringsarbeten : En studie om möjliga förbättringar i arbetsmiljön vid armeringsarbeten
Injuries and sick-leave is a common feature for reinforcement workers today. This is mainlydue to the fact that reinforcement work is done in an exposed environment with many stressfactors and highly repetitive work. These operations are often carried out in unsuitableworking positions, these positions creates a major burden on the bones and joints and causesmicro- damages on muscles. With repetitive work these injuries are not given time to healproperly and will gradually become worse.The body will not be able to handle the stress of working in a work environment such as thisand musculoskeletal disorders can be a result of this. The injury will make itself known aspain in the musculoskeletal system and causes reduced movability; the injured worker willtherefore not be able to perform the same work tasks as before.
Dimensionering av betongkonstruktioner : En jämförande studie av BBK 04 och Eurokod 2 vid dimensionering av balkar och pelare
Today, we use BKR and BBK 04 when designing concrete structures inSweden, which will, in the near future, be replaced by Eurocode 2. When you are designing buildings, you will use Eurocode 2 Part 1-1 and with this new standard, some new rules and general rules will be necessary to adopt. To examine how BKR and BBK 04 tells apart from Eurocode 2 when designing concrete structures, one beam and one column with often common dimensions, is studied. The beam is designed with consideration of (considerate to) durability at bending moments, shear forces and control of cracking. The column is designed with consideration of durability at eccentric axial load and bending moments in cross section on account of (due to) geometric imperfections. BBK 04 has gone one step closer to Eurocode 2 than earlier editions and the things that are different, when calculating reinforcement, is how they use the partial factors.
Vertikalarmering i tegelbalkar ur arbetsmiljöperspektiv
Statistics of occupational injuries show that bricklayers are among the most exposed, with heavy lifting by far the most common cause of long-term sick leave. Prefabricated brick beams create yet another risk of injuries that can be prevented by auxiliary equipment or alternative solutions. From articles, interviews with masons and from a survey carried out in conjunction with this report, it appears that there are frequently difficulties in the use of available means for lifting and handling. Previous studies on the subject of transverse reinforcement in masonry beams indicate a viable method for bridging large openings in masonry walls. This bachelor thesis delves into whether the idea could be realized in today's brick construction with a view to improving occupational health and safety.
Att effektivisera armeringsarbete : Från idé till genomförande
Most of today?s concrete structures that are built on site are mainly constructed in a traditional fashion with a lot of artisanal operations. One step towards industrializing the in-situ construction of concrete is to use prefabricated reinforcement. Through this method there can be a lot of savings when each bar doesn?t have to be placed and fixed separately on site.
En jämförelse mellan betongarmeringsverktygen i TEKLA Structures och ADT
Vid uppritandet av byggmodeller på WSP Group i Norrköping använder man idag två program: TEKLA Structures och AutoCAD Architecture. En av anledningarna till detta är att armeringsverktyget Impact Reinforcement i AutoCAD Architecture fungerar bättre än armeringsverktygen i TEKLA Structures. Då man behöver armering i en TEKLA Structures modell exporteras denna till AutoCAD Architecture där armeringsjärnen sedan ritas in. Jag har därför undersökt skillnaderna mellan de båda programmens armeringsverktyg, resultatet är att Impact Reinforcement är lättare att använda medan TEKLA Structures tar längre tid att lära sig, men skulle kunna göra arbetet effektivare med rätt kunskaper..
En jämförande studie av några fritidslärares och klasslärares syn på formellt och informellt lärande
The aim of this thesis was to investigate how teachers in school and in leisure time center look at informal and formal learning. Informal learning is often associated with leisure-time while formal learning is generally linked to school. My questions also deal with the teachers? view of each other?s activities from a learning perspective and visibility of informal learning. I have made an empirical study with qualitative, semi-structured interviews with three class teachers and three leisure teachers.
