Foraging behaviour of cattle, sheep and goats on semi-arid pastures in Kenya

ABSTRACTThe principal aim of the study was to compare the feeding behaviour of cattle, sheep and goats on pasture and explain any differences between speices. Furthermore, I compared foraging behaviour between dry season and the beginning of the rainy season, in order to see any relationships between weather and behaviour.The study was carried out in Shompole in southern Kenya. Behavioural data were collected by observing herds of cattle, sheep and goats on pasture. The livestock were herded on pasture during the days and kept in bomas, where people live, during the nights. The weather in Shompole is characterized by high ambient temperature and low, bimodal rainfall.

Utvecklingen av mekatronikämnet på KTH : ? anställningsbarhet, forskning och innovation

This thesis examines history of the subject of mechatronics and innovation. The main reason tostudy mechatronics from a historical point of view is that it has never been done to a greater extent before. An overview is justified because various definitions have been used over the decades, but nowadays the subject has become more established. Focus in this thesis is mainly on development of the subject of mechatronics at Royal Institute of Technology in Stockholm. Innovation is the other aspect of this thesis.

Sveplaserns användning till inventering/befästning/kontroll av vägmarkering

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Optimering av sintrade kugghjul

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

Användbarhet för grafiska designers - Responsiva webbplatser och dess utformning

Idag besöker vi inte längre webbplatser enbart via datorer, utan även mobiltelefoner och surfplattor. För att göra interaktionen på en webbplats användbar via flera olika plattformar blir det allt vanligare med responsiv anpassning. Denna utveckling ställer högre krav på den grafiska formgivaren som bör ha god kunskap om de plattformar som designen tillämpas på för att nå högsta möjliga användbarhet. En grafisk formgivare ska alltså förstå vad användbarhet innebär och hur denna kunskap ska tillämpas i designen. Kandidatarbetet undersöker vad som definierar användbarhet och vad grafisk design bidrar till i skapandet av responsiva webbplatser. Utifrån litteraturstudier i samband med en produktion i form av en responsiv webbplats, presenterar vi i detta arbete våra metoder för hur den grafiska designen ska uppnå användbarhet oavsett plattform. ---- We no longer visit websites solely by using computers, but also mobile phones and tablets.

Användargenererad data i tjänstedesignprocessen

Syftet med studien är att ta reda på hur tre olika innovativa tekniker kan användas för att samla in användarinsikter i en tjänstedesignprocess. Detta genomförs med ett designcase som handlar om besökarnas upplevelse av Norrköpings Symfoniorkesters konserter. Symfoniorkestern behöver hjälp med att locka fler besökare till konserterna och nya sätt behöver användas för att samla in användarinsikter för att få så många olika perspektiv som möjligt av konsertupplevelsen.Det var 20 personer som deltog i studien med en blandning av personer, dels de som idag går på Norrköpings Symfoniorkesters konserter och dels de som inte besöker dem. Deltagarnas uppgift i studien var att gå på två av deras konserter och dokumentera sina upplevelser med hjälp av tre olika innovativa tekniker: designsond, app och automatisk kamera.Resultatet av studien visar att den första tekniken designsonden gav en fördjupad bild av deltagarnas syn på konsertupplevelsen och hjälpte till att bredda fokus i tjänstedesignprocessen. Den andra tekniken,appen, kunde ge en mer detaljerad information i realtid om deltagarnas konsertupplevelse på plats.

Fruits of knowledge : a literature review of marketing strategies and mango production in Kenya

This report is a literature review that aims to describe marketing contexts for mango production in Kenya. The institutional conditions in the country are not well developed for marketing purposes, which causes many difficulties and problems for the society. In Kenya most mango producers are poor small-scale farmers with limited resources. Mango is a perishable commodity and to keep its value and quality it is essential to have the opportunity to sell the mangos in the right time. Inefficient and undeveloped infrastructure and marketing systems hinders the mangos to reach the market in time though, which causes large losses of produce.The Kenyan mango production has increased during the last decade but due to market losses for the producer, the small-scale farmers? profits have not improved.

Flexibla fixturer i bearbetande maskiner

This thesis was conducted at Linköping University and Saab Aerostructures DPS, Linköping, and focuses on the possibilities of flexible fixturing in machining applications. The thesis is part of the research project "Koofix", which is collaboration between Linköping University and a number of companies.The thesis is aimed towards small batch production which, for Saab Aerostructures DPS, means diverse part geometry and that parts are manufactured in very small numbers, sometimes just one piece. The result of this is that expensive dedicated fixtures are made for most parts. By introducing more flexible fixturing methods to this kind of production the cost of fixtures and tooling will be reduced, and make the production more efficient.New flexible fixturing methods has been presented and evaluated through the thesis, which has resulted in three different concepts. These concepts have been the result of literature screening and study of current manufacturing process at Saab Aerostructures DPS.
