  2. 21. Code-switching for all practical purposes : Bilingual organization of children's play

    Author : Jakob Cromdal; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Childhood bilingualism; Code-switching; Play dialogues; Social interaction; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This study examines bilingual children's code-switching practices as they occur in multiparty play activities in an English school in Sweden. By focusing on the endogenous organization of play events, the study contributes to our understanding of bilingualism as both resource for and result of children's social conduct. READ MORE

  4. 22. Evaluating the Swedish mobile communications market: Switching costs and network effects

    Author : Pratompong Srinuan; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Switching costs; competition; network effects; termination-based price discrimination; Swedish mobile communications market;

    Abstract : The Swedish mobile communications market has been facing telecommunication liberalization since 1993. The telecom regulator has implemented many regulations in order to ensure that competition in the mobile communication market is intense and consumers have various choices of services with fair prices.

  5. 23. Self-Switching Diodes for Zero-Bias Terahertz Detection

    Author : Andreas Westlund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-switching diode; noise-equivalent power; SSD; graphene; zero-bias; InAs; InGaAs; terahertz; detector;

    Abstract : The self-switching diode (SSD) has been investigated as a potential terahertz detector in recent years. The SSD accomplishes a non-linear current-voltage relation through a field-effect, which enables detection at zero bias from microwave up to terahertz frequencies. In this work, SSDs were realised in two new materials; InAs and graphene. READ MORE

  7. 25. On possibilities of smart meters switching at low voltage level for emergency grid management

    Author : Yasir Arafat; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical distribution grid; Smart grid; Remote switching; Smart meter.; Power quality; Power quality measurement;

    Abstract : Smart Meter (SM) is an advanced remotely readable energy meter with two-way communication capability which measures the electrical energy in real-time or near-real-time and securely sends data to Distribution System Operator (DSO). A smart metering system is an application of SMs on a larger scale, i.e. READ MORE
