Professional Digital Encyclopaedias as Socio-Technical Systems

This paper presents on-going research on the production of knowledge in contemporary professional digital encyclopaedias. By adopting a theoretical perspective that considers the interplay of humans, non-humans and practices at the same level, it develops further a socio-technical perspective on knowledge production. Methodologically, the project involves an ethnographic study staring from two edi

A Look at the Roles of Look & Roles in Embodied Pedagogical Agents - A User Preference Perspective

. The paper presents a theoretical framework addressing three aspects of embodied pedagogical agents: visual static appearance, pedagogical role, and communicative style. The framework is then applied to a user study where 90 school children (age 12 15) in a dummy multimedia program were presented with either an instructor or a learning companion condition. They were then to choose between eight v

Palmitate-induced beta-cell dysfunction is associated with excessive NO pro-duction and is reversed by thiazolidinedione-mediated inhibition of GPR40 transduction mechanisms

Background: Type 2 diabetes often displays hyperlipidemia. We examined palmitate effects on pancreatic islet function in relation to FFA receptor GPR40, NO generation, insulin release, and the PPARgama agonistic thiazolidinedione, rosiglitazone. Principal findings: Rosiglitazone suppressed acute palmitate-stimulated GPR40-transduced PI hydrolysis in HEK293 cells and insulin release from MIN6c cell

Konsumtion av bekväma funktioner. Elanvändning i hushåll.

Gemensamt för både direkta och indirekta el-kunder är att de konsumerar en osynlig produkt, energi. Hushållen behöver inte vara intresserade av energi eller dess ursprungskälla, men väl de tjänster som energiföretagen kan bidra till att leverera. Man köper funktionen kall öl, varmt kaffe, rena kläder, ren kopp, lyssna på radio, se på TV, medan energiföretagen säljer den immateriella tjänsten och o

Dual Supply-Voltage Scaling for Reconfigurable SoCs

By partitioning a hardware design into several blocks and adjusting the voltage of the different blocks individually, an overall power consumption reduction is possible. An algorithm and a hardware solution for assigning two supply voltages to a design divided into blocks is presented. The two supply voltages are optimized using an on-chip controller. The on-chip controller assigns one of the two

An On-Demand WebRTC and IoT Device Tunneling Service for Hospitals

In this paper we present the implementation of a WebRTC gateway service that can forward ad-hoc RTP data plane traffic from a browser inside a local hospital network to a browser on a local home network. The gateway leverages the same infrastructure used by the hospital to tunnel sensor and control data for medical devices in home-care deployments. In our use case, doctors at hospitals can only ac
