… breed differences in theses parameters. Additional aims were to study if transportation could influence the re-sults obtained and to compare the two indirect blood pressure measurement devices, the Cardell® Veterinary Vital Signs Monitor (Cardell) Model 9402, and the HDO Memo …
Genom simulering och praktiska försök
… i en pneumatisk tork. Pneumatisk tork fungerar genom att ett luftflöde transporterar och torkar ett vått material. Fördelarna med en pneumatisk tork är den korta torkningstiden, samtidigt som materialet får en jämn fuktkvot. Den korta torktiden bidrar dessutom med att utsläpp av …
Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model …
The aim of this project was to develop a numerical model simulating the global transport of air pollution. The model currently used by SMHI, the Swedish Meteorological and Hydrological Institute, was intended to perform such simulations at regional scales. However, the usage of …
en studie genomförd på Sveaskogs marker i Norrbotten
… ”Model builder”. High stock concentration in combination with long terrain transport distance means great necessity of roads. The areas with the biggest necessities get the highest prior for road-building, and a road proposal is drawn to every such area. A road proposal is drawn …
… that are the most important ones in the tests within this thesis is timber transport, forest fuel transport, machine movement, increase in production at the edge of the road, lost of production in the road, winding factor and flexibility.
En studie av en modell om uppfattningar av färdvägsmiljön hos cyklister
Summary Aim The study examines a theoretical model developed to capture cyclist´s perceptions of the route environment. The survey focuses on if level two and three in the theoretical model captures what it´s intended to do. More specific we ask ourselves how the three …
Approximately 60 million cubic meters of round wood are transported every year with trucks in Sweden and stand for 15 % of all truck transportation in the country. The big amount that is transported results in many haulage companies works in different parts of the country with …
Studie över ICA:s CSR-arbete inom transport av varor
… Branschen har ett välutvecklat och komplext logistiksystem där transportverksamheten är en central funktion. Syftet med denna studie är att beskriva och utvärdera dagens CSR-arbete ur ett miljöperspektiv inom livsmedelsbranschens transportverksamhet. Utifrån en litteraturstudie …
flöden, drivande faktorer och modellering
… distributionssystem. Arbetet omfattar analys av samband mellan elementen, transportberäkningar per ytenhet av elementen till Mälaren och en modelleringsansats för ett av avrinningsområdena. Rapporten innehåller även en jämförelse mellan de olika vattenföringsmodellerna samt …
… for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal …
… scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from …
exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
… the choice of geographic scale of (trading) regions and related assumptions on transport cost functions.
… this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake. The model was parameterized from literature values, measured values, calibration and evaluated using measured data from a field site called …
… dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data …
