Real-Time Lossless Compression of SoC Trace Data

Nowadays, with the increasing complexity of System-on-Chip (SoC), traditional debugging approaches are not enough in multi-core architecture systems. Hardware tracing becomes necessary for performance analysis in these systems. The problem is that the size of collected trace data through hardware-based tracing techniques is usually extremely large due to the increasing complexity of System-on-Chip

Effekter av partneringsamarbete i byggbranschen

Samarbete och teamkänsla är vanliga begrepp på många arbetsplatser oavsett bransch. Aktörerna i byggbranschen är inte kända för att vara några pionjärer inom detta område utan branschen har historiskt sett snarare beskrivits som konservativ och konfliktfylld, vilket bidragit till att försämra byggbranschens rykte. En förändring håller på att ske, att olika aktörer kan jobba tillsammans för att nå

Firmware update in a resource constrained environment

An embedded system’s software is often the backbone for a successful prod- uct. To make the system stand out from the other competitors on the mar- ket, your system must be adaptive and ready for quick updates. However, one may never truly know where your system is going to be used and how difficult it can be to access and update it. Here we show a solution that securely updates a system based upo

High-loaded Activated Sludge: Effects of Different Aeration Strategies at Sjölunda WWTP

Sjölunda avloppsreningsverk är ett av de största reningsverken i Sverige och tar hand om avloppsvatten från stora delar av det snabbt växande Malmö. Befolkningsökningen sätter press på verket, där vattenreningen måste förbättras för att reningsverket ska kunna ta hand om ökande volymer avloppsvatten. För att nå detta mål drivs flera förbättringsprojekt på Sjölundaverket, däribland projekt som fokuThe activated sludge process has existed for over a century and despite its age the development of new theories, methods and technologies is ongoing. Despite huge technological breakthroughs in the last decades the activated sludge process is still a very energy demanding process however, and it is possible to make significant energy savings by optimizing the aeration strategy of an activated slud

Statusövervakning av plattvärmeväxlare - med hjälp av modellsimulering i Simscape

The steel company SSAB in Borlänge has five plate heat exchangers that they use to cool the process water. The water is used to cool the steel after hot rolling. The exchangers need to be cleaned sometimes because of fouling, that reduces the cooling efficiency. This results in higher energy use and higher costs in the end. The goal of this paper is to create a model of a plate heat exchanger to m
