… During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up. Time navigation enables a user to go back to any prior state and easily examine a …
Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management<em> </em>
… to it. An area about the importance of eliminating storage is JIT or just in time. The main principle of JIT is that a product shouldn’t be produced until a customer expresses its demand for it. Inventory Management is an area within JIT and contains different principles …
… in a fine paper. Samples were collected from each second tambour during a time period of two weeks from a paper machine at MoDo Paper, Husum. Two data sets, consisting of 20 and 95 observations, were selected for extensive analysises of tensile and structual properties. The data …
… is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel …
… of a proper distribution of blades to produce a big amount of them at the same time. 2.- Research of the best production process to produce the blades. 3.- Main design of the machine to produce the blades. In the Thesis these three points are carefully developed and studied in …
… there are plenty of gas- and oxide-porosity. It has been proved that every time the dies temperature decreased below 120 °C the content of gas porosity increased. It is due to rapid solidification of metal that flows through the ”cold” laminate. It has confirmed that enhanced …
… what a combine harvester can harvest in one season, this also involves the timeliness-costs and the probability of good weather. We have used a calculation program to calculate hours of labour, fuel consumption and machinery costs. In this study we show how much time and fuel …
… must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary …
… whose electrical characterizing parameters (resistances, inductances and time constants) are unknown. The aim of this thesis is to characterize the machine in its current state by perform a Standstill Frequency Response (SSFR) test. From the analysis of the measurement data …
… will be remodelled radically, thus the improvements must give a short payback time or have a value even after the remodelling. A conclusion drawn from our calculations is that the efficiency of the central cooling is low. The average COP 2(Coefficient of performance in the …
… transport distance by half. By dividing the costs in terminal and transport time, the different cost items can be compared. This shows that road transport cost may be significant with longer transport distance. Despite this, the most expensive cost item in first thinnings is …
… control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis. The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built …
en fältstudie på känsliga marker
… and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground …
… that the injection molding method might be a good method, but it requires more time and it also requires product development to make the method optimal.
Studie av olika metoder för att reducera bakterier
… in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since …
