… in Öhlins shock absorbing systems sets great demands on the contacting surfaces. In this particular case, the bushings and the sealings on a cylinder piston. The surface wanted is a surface with both low frictional forces and small leakage. This study was done with the goals of …
att gestalta praktfulla parker som kan skötas på ett hållbart sätt
… specific climate and place. Another important issue is to make sure that all surfaces are properly built up with protection against weeds that spread by their roots. Surfaces with stone or gravel are mainly to be built where it's necessary due to use, since well-used hard …
Examensarbete om släpliftar
… ropeway engineering. The degree project goal was to develop a new shaping of a surface lift. There are two kinds of surface lifts, platter and T-bars. The two kinds of surface lifts have some variation in design but only minor differences. The project focused solely on the part …
from a methodological perspective and a conceptual framework
… of landscape urbanism are derived from the interpretation of landscape as surface and ecosystem. Landscape as surface interprets landscape as a thick mat and heterogeneous field where landscape is regarded as an infrastructure that can organise the city. Interpreting the …
En undersökning om hur designen på en Microsoft Surface SUR40 applikation kan förbättras för flera användare
… this thesis is to examine and analyze how to improve the design of a Microsoft Surface SUR40 application. The application in focus was an interactive product browser developed by the company Spree, our external client. Spree is a multi-touch software provider, established in …
… substances ivermectin, spinosad and barettin to hydrophobic and hydrophilic surfaces, and to analyze and study if the barnacle larva are effected when they try to settle on the treated surface. Incubation tests with barnacle larva in Petri dishes were performed as well as …
En modelljämförelse
… of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface …
Vass, bredkaveldun och gäddnate i Bergviks dagvattendamm
Abstract Surface-water includes different kinds of pollutants from traffic and roads. To prevent these pollutants to reach nearby lakes one can construct surface-water ponds on locations with heavy traffic. At Bergviks shopping centre in Karlstad, two ponds, one smaller and one …
vilken information ger berggrundens överyta?
… was to examine whether topographic water divides delimited from the ground surface topography could be used to delineate recharge areas for aquifers. For this purpose, topographic water divides from Svenskt Vatten ARkiv (SVAR) were used. The results show that it is possible to …
en jämförelse mellan idag och 1970-talet
Storm water is rain and melted snow that runs off, primarily from impervious surfaces.Future storm water management is facing the challenges of increased precipitation, asclimate changes, and increased areas of impervious surfaces due to the expansion anddensification of the …
Investigation of bondning mechanisms at the pressing of metal laminates
… of the mechanisms that operate in conjunction with the welding of metal surfaces may help to improve existing manufacturing processes, and to enable new products and combinations of materials. The purpose of the project has therefore been to acquire a deeper understanding of …
Beräkning av utnyttjningstid för en uppvärmd konstgräplan med alternativa rörplaceringar
… is to create a mathematical model using computer programs that describe the surface temperature over a year. For artificial turf pitch to be playable the surface temperature should be at least 0°C. The model whose task was to describe the surface temperature was built in the …
En studie på spridning av partiklar genererade från brand
… the transportation was influenced by sieving or physiochemical particle and surface interactions. The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining. The particle size and the surface …
studie av påverkande faktorer
… and this has influenced the water quality negatively. The waterworks is a surface waterworks which takes its raw water from the lake Sjöbysjön. The water is flocculated and filtered in a contact filter with the flocculent EKOFLOCK 91. Thereafter it is alkalinized before it …
en fältstudie
… used in the field investigations was the light weight deflectometer (LWD), surface seismic and static plate loading. The different devices were used because they take measurements at different load- and strain levels. Another aim was to investigate correlations between moduli …
