LTH:s SI-verksamhet på gymnasiet är ett samarbete mellan LTH och elva gymnasieskolor i närregionen som startade under hösten 2007 och går ut på att använda den s.k. SI-metodiken som komplement till den ordinarie undervisningen i naturvetenskapliga ämnen. SI-mötena leds av teknologer från LTH. Syftet med samarbetet är flera: att förbättra samverkan mellan LTH och gymnasieskolor i närregionen; öka i

This memo reports on factors that drive and inhibit the digitalization of security systems. The reported factors are as follows: Technology-push factors • Need to lower costs on the end-user side, i.e. replacing labour with technology • Perceived convenience and ease-of-use of digital systems • Digital products can be connected to the current enterprise network; enabling an expanding set of secur

This paper examines how social relations and norms contribute to the emergence of generalized trust in economic action. Our core proposition is that the more positive the local social exchange relationship, the greater an actor’s propensity to place trust in strangers. Our research design integrates behavioral measures elicited by incentivized experimental trust games with survey data using a rand

The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with 180-deg turn under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase the blade tip lifetime. Di

This paper presents a hardware mapping of an auto-correlator for Orthogonal Frequency Division Multiplexing stage for three radio standards: LTE, DVB-H, and IEEE 802.11n. Hardware cost is minimized by using only the sign bit in the autocorrelation function. The frequency offset estimation procedure is dramatically simplified by reducing the phase of the envelope to pi/2 resolution, which in turn r

Combustion phasing in a Homogeneous Charge Compression Ignition (HCCI) engine can be achieved by affecting the time history of pressure and temperature in the cylinder. The most common way has been to control the inlet air temperature and thereby the temperature in the cylinder at the end of the compression stroke. However this is a slow parameter to control, especially cycle to cycle. A multi- cy

This article deals with depictions of humans during the Vendel and Viking Age. While in earlier research, the iconographic approach has been predominant, the point of departure here are the functions pictures may have had in oral societies. As a new approach, the method of context analysis is presented. The main question is how depictions have been used differently by different social groups. In t
