2. 1. Energy Efficiency in Residential Buildings in Mozambique - Measurements and Simulations

   Author : Gabriel Auziane; Byggproduktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Building; Measurements; Simulations; DEROB-LTH; Mozambique; Subtropical and Tropical climates; Energy efficiency; PV system; Electrical energy savings.;

   Abstract : Mozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. READ MORE

4. 2. Multi-dimensional approach used for energy and indoor climate evaluation applied to a low-energy building

   Author : Fredrik Karlsson; Bahram Moshfegh; Hazim Awbi; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-energy building; energy; indoor climate; simulation; Lågenergihus; energi; inomhusklimat; simulering; Building engineering; Byggnadsteknik;

   Abstract : The building sector alone accounts for almost 40% of the total energy demand and people spend more than 80% of their time indoors. Reducing energy demand in buildings is essential to the achievement of a sustainable built environment. At the same time, it is important to not deteriorate people’s health, well-being and comfort in buildings. READ MORE

5. 3. Efficient Integrated Circuits for Wideband Wireless Transceivers

   Author : Quoc-Tai Duong; Atila Alvandpour; Henrik Sjöland; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The proliferation of portable communication devices combined with the relentless demand for higher data rates has spurred the development of wireless communication standards which can support wide signal bandwidths. Benefits of the complementary metal oxide semiconductor (CMOS) process such as high device speeds and low manufacturing cost have rendered it the technology of choice for implementing wideband wireless transceiver integrated circuits (ICs).

6. 4. Continuous-time System Identification : Refined Instrumental Variables and Sampling Assumptions

   Author : Rodrigo A. González; Cristian R. Rojas; Marion Gilson-Bagrel; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Continuous-time systems; Refined instrumental variables; band-limited signals; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Continuous-time system identification deals with the problem of building continuous-time models of dynamical systems from sampled input and output data. There are two main approaches in this field: indirect and direct. In the indirect approach, a suitable discrete-time model is first determined, and then it is transformed into continuous-time.

7. 5. Flight Test System Identification

   Author : Roger Larsson; Martin Enqvist; Lennart Ljung; Roy Smith; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : With the demand for more advanced fighter aircraft, relying on unstable flight mechanical characteristics to gain flight performance, more focus has been put on model-based system engineering to help with the design work. The flight control system design is one important part that relies on this modeling. READ MORE
