… nutrition elements, flow, oxygen concentration, suspended solids, organic load and microbial activity. At two occasions, the parameters were extensively studied during a 24-hour period respectively. Two capacity experiments were performed in order to evaluate the organic …
växthusgaser, energi- och resursanvändning i modellstudie
… executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems. All simulations …
Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?
… was installed. The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) …
… The harder the bales are, the cheaper the management gets. Vehicles with low load platform (0,9 m) can carry bigger load, which also reduces costs. A combination, where both bale density and transport volume are maximized, gives transportation costs almost as low as the costs …
Detta arbete var beställt av Sjöfartshögskolan i Kalmar. Skolan ville ha en enhet som kunde mäta aktiv-, reaktiv- och skenbar effekt, ström, spänning, frekvens och cos? på en generator och som kommunicerade vidare dessa värden till en PLC. Detta för att kunna lastfördela lasten …
… Further, testing was conducted to obtain cell-generated heat power at varying load, state of charge and temperature. Henceforth the test data was used for the creation of simulation models in (COMSOL, 2012) and numerical analysis in (MATLAB, 2011) regarding the battery system's …
… of natural catchments. The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high …
… an expansion of the horse keeping may affect the risk of enhanced phosphorus load to the nearby lake system Vansjön ? Nordsjön. The risks associated with outdoor horse keeping are an accumulation of phosphorus in the soil profile caused by dung deposition and roughage residues …
… of the Ethernet controller provides the highest efficiency gain at different load levels. This work also investigates whether implementation of dynamic frequency scaling on a new processor is a complex task or not. Implementations in the Linux kernel provide general code that …
… of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together. An important subsystem is the engine management system. This project is about …
Dess för- och nackdelar
… but to a high cost. Furthermore has the self scanning system reduced the work load for the personnel but increased the stress factor. The customers on the other hand have experienced the self scanning system as a more flexible system. Still the fruit and vegetables department …
substance flow analysis on a regional level
… way of improving Nr management could be to eat less protein, i.e. give less Nr load into WWTP. The conclusions are that Scania leaks Nr to air, water and soil. The nitrogen management generally needs to be improved to become sustainable and there is a great potential for …
Potential för att minska tomgångsförluster med industriella styrsystem
… performed on machine tools at a Scania production site in Södertälje. Through load measurements the potential for energy savings was determined. The results show that there is a great potential for energy savings during idle times at the site. 20 to 50 percent of the machines? …
fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling
… is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time …
Bidraget till minskade förluster
… power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted …
