1. 6. Hydrological Transport in Shallow Catchments: : tracer discharge, travel time and water age

   Författare :Sofie Safeyeh Soltani; Vladimir Cvetkovic; Bijan Dargahi; Jan Olof Selroos; Andrea Rinaldo; KTH; []
   Nyckelord :Hydrological transport; travel time; water age; tracer discharge; Lagrangian pathway approach; pathway lengths; numerical modeling; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : This focuses on hydrological transport in shallow catchments with topography-driven flow paths. The thesis gives new insight to kinematic pathway models for estimation of tracer discharge at the catchment outlet. LÄS MER

3. 7. Electrical Characterization of Partial Discharge Resistant Enamel Insulation

   Författare :Tuan Anh Hoang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Enamel wire insulation; dipolar polarization; charge injection; charge transport; chromium oxide; dc conductivity; partial discharge; twisted pair.; dielectric permittivity;

   Sammanfattning : Adjustable speed drives for rotating machines have become increasingly popular as they provide possibilities of smooth and accurate process control as well as for energy savings. In such systems, due to the fact that the voltage applied at terminals of motor windings is no longer purely sinusoidal but characterized by a high content of harmonics, the appearing electrical and thermal stresses yield premature failures of the winding insulation, mainly because of an increased partial discharge (PD) activity.

4. 8. Numerical simulations of flow discharge and behaviours in spillways

   Författare :Shicheng Li; Anders Ansell; James Yang; Sébastien Erpicum; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spillway; step geometry; discharge prediction; flow behaviour; machine learning; computational fluid dynamics; Utskov; steggeometri; avbördningsuppskattning; flödesbeteende strömningsegenskap; maskininlärning; flödesdynamisk beräkningsanalys numerisk simulering; Betongbyggnad; Concrete Structures;

   Sammanfattning : A spillway is an important component of a dam and serves as a flood release structure. It achieves controlled discharge of water and protects the dam from overtopping. The majority of the hydropower dams were built before the 1980s, and many spillways are undersized in light of the present design flood guidelines. LÄS MER

5. 9. Ansvarsfrihet : Dechargeinstitutet i svensk aktiebolagsrätt

   Författare :Carl Svernlöv; Svante Johansson; Daniel Stattin; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; corporate governance; directors liability; decharge; discharge; bolagsstyrning; styrelseansvar; ansvarsfrihet; LAW JURISPRUDENCE; RÄTTSVETENSKAP JURIDIK; Legal Science; rättsvetenskap;

   Sammanfattning : This dissertation examines discharge from liability in the Swedish limited liability company. Under Ch. 7 § 11 of the Swedish Companies Act 2005, the shareholders shall at the annual general meeting resolve on whether to grant discharge from liability to the board members and managing director. According to Ch. LÄS MER

7. 10. Climatic signals and frequencies in the Swedish Time Scale, River Ångermanälven, Central Sweden

   Författare :Mikkel Sander; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; klimatologi; pedology; cartography; climatology; Fysisk geografi; geomorfologi; geomorphology; Physical geography; winter precipitation; climate change; central Sweden; last 2000 year; discharge; varve;

   Sammanfattning : Any future climate variation forced by human activities will be superimposed on the background of natural climate variation. Therefore, before interpreting the present climate and addressing future climate scenarios some knowledge of past climate is necessary. LÄS MER
