    Causes of Poor Air Quality in Swedish Schools2006Conference paper (Refereed)
    Abstract [en]

    This literature survey distinguishes between building and other factors influencing air quality. It does not identify building factors sufficient to account for occupant complaints. It concludes that buildings are often blamed for adverse health effects without sufficient grounds. The risk is there will be too much focusing on the wrong underlying problem when remedying so-called sick buildings. The study shows the importance of ensuring that factors independent of the school building, including the choices of environments and activities, are important for the indoor environment.

    Ventilation Strategy to improve health and productivity conditions2006In: HB - Heal. Build.: Creating Heal. Indoor Environ. People, Proc., 2006, p. 421-424Conference paper (Refereed)
    Abstract [en]

    This paper was mainly based on a literature review and focused on control of emissions and on thermal comfort conditions in office buildings. The ultimate goal was to identify optimal conditions for both human health and work productivity in office room environments. Good indoor air quality (IAQ) was to be achieved at low emission rates and correct indoor air temperature. Different ventilation and air conditioning strategies were evaluated and compared. Both energy and environmental aspects were considered. Analyses were made for emission rates of various indoor sources such as outdoor pollution, construction materials, furnishings, office-equipment and consumer products.

    Effectivity of a Suction Cylinder as Ventilation Equipment2006Conference paper (Refereed)
    Abstract [en]

    This paper proposes to use free wind to create suction pressure within a ventilation duct without consuming commercial energy. Like an ejector pump it creates suction pressure placed above the ventilation exhaust, which is used to draw exhaust air from the ventilation system. Discussing the possibilities of this suction cylinder concept in ventilation system is the objective of this paper. Here, a mathematical model was deduced for a suction cylinder and through CFD (Computational Fluid Dynamic) technique result was simulated later compared with theoretical model. GAMBIT was used as a preprocessor and for processing FLUENT, a commercial CFD code, was used for the simulation. Preliminary result clearly shows the positive advantages of using a suction cylinder as ventilation equipment.

    Monitoring of SIP-based communication using signalling information for performance measurements2006Conference paper (Refereed)
    Abstract [en]

    This paper presents a prototype implementation of end-to-end monitoring of performance parameters in SIP-based communication. The approach is to integrate signalling information and measurements of user data traffic. Test measurements illustrate some results that can be obtained per session; packet loss, roundtrip delays and their variation, inter-arrival jitter and throughput.

    Automatic quantitative evaluation of emotions in E-learning applications2006In: Annu Int Conf IEEE Eng Med Biol Proc, 2006, p. 1359-1362Conference paper (Refereed)
    Abstract [en]

    The long term goal of our research is to develop a tool for recognizing human emotions during e-learning processes. This could be accomplished by combining quantitative indexes extracted from non-invasive recordings of four physiological signals: namely skin conductance, blood volume pulse, electrocardiogram and electroencephalogram. Wearable, non-invasive sensors, communicating with a PC, were applied to 30 students and data were collected during exposure to three different computer-mediated content stimuli designed to evoke specific emotional states: stress, relaxation and engagement. In this paper we describe both the general emotion evaluation algorithm, and present a preliminary results suggesting that some of the quantitative indexes may be successful in characterizing and distinguishing between the three different emotional states.

    Current Source for Wideband Electrical Bioimpedance Spectroscopy Based on a Single Operational Amplifier2006In: WORLD CONGRESS ON MEDICAL PHYSICS AND BIOMEDICAL ENGINEERING 2006, VOL 14, PTS 1-6 / [ed] Kim, SI; Suh, TS, 2006, p. 707-710Conference paper (Refereed)
    Abstract [en]

    Traditionally, measurements of electrical bioimpedance for medical diagnostic purposes have used only low frequencies, usually below 100 kHz. The analysis focused only on the resistive part of the impedance; very often at low frequencies the reactive part of the impedance is negligible. Recent studies of the electrical bioimpedance spectrum, both real and imaginary parts, have indicated new potential applications e.g. detection of meningitis, skin cancer assessment and brain cellular edema detection. An important functional unit in a wideband impedance spectrometer is the current source used to inject the current into the tissue under study. A current source must provide an output current virtually constant over the frequency range of interest and independent of the load at the output. Several designs have been proposed over the years but the performance of them all degraded markedly near bellow 1 MHz e.g. Ackmann in 1993, Bragos et al in 1994 and Bertemes-Filho et al in 2000. The development of electronic technology has made available devices that allow us to obtain a current source with large output impedance, larger than 100 k Omega, above I MHz and based in a simple single Op-Amp circuit topology. Simulation results and experimental measurements are compared and the most important parameters of the VCCS are analytically studied and experimentally tested, including the dependency to changes in the circuit elements and the incidence of the Op-Amp parameters on the current source features.
