… chlorine was determined. Soil samples were collected at 49 of the nodes in a grid with approximately 105 m between the nodes. The analysis of spatial variability suggested that no spatial autocorrelation was present either within the variable organic chlorine or chloride. This …
… in an indirect way. They subdivide the object definition space in a regular 3D grid and verify that a voxel belongs to the object by verifying that its 2D projection falls inside the silhouette of the corresponding image. Our scanner adopts a direct method: by using a new 3D …
… technique, mainly applied to transmissionvoltage level. The Swedish grid is characterized by long distances betweenpower plants and customers, hence long transmission lines carrying loads of varyingsizes are frequent. This implies that reactive power compensation by capacitors …
… a hardware language as VHDL, and implement it into an FPGA (Field Programmable Grid Array), makes the development of applications fast and cheap.
… the possibilities to chart, analyze and present the vulnerability in a power grid. In this report it has been, using power outage statistics, possible to verify, that network theories can be used to evaluate the vulnerability of an infrastructure network. However further studies …
etanol som fordonsbränsle
… process. Some plants are even capable of selling surplus electricity to the grid. There are two kinds of ethanol produced: anhydrous, which contains no water and hydrous, or hydrated which contains some five percent of water. The anhydrous ethanol, with 99.5 % alcohol can be …
… this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this …
… deras agerande i en reel köpsituation. Vi har utgått från teorier såsom FCB-grid, TORA-modellen samt en modell över konsumenters attityd till att handla etiskt. Vi har även belyst informationsbehovet och dessutom tagit del av fyra stycken undersökningar som tidigare gjorts kring …
- en studie av produktionsmetoder
… active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common. The aftermath of the hurricane ”Gudrun” has forced several power companies to re-evaluate their electric supply network, which has …
… plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines …
En jämförande studie om ledarskap inom verkstadsindustrin
… som finns inom området med utgångspunkt ibland annat Blake och Moutons Grid-modell, samt McGregors teori X och Y. För att ta reda på om det finns några skillnader chefer och medarbetare emellan har vi använt oss utav den kvalitativa forskningsmetoden, detta då de kvalitativa …
… from 1999, by The Urban Task Force. A MODEL FOR SOCIETY FORMATION - Linear Grid - Ylva Hedin ? A vision for the Helsinki Regions urban structure from 1993, by Arken Arkitekter. First our study objects are introduced and analysed one by one, then follows a text where the objects …
… due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which …
