  2. 1. The Block Error Rate in Block Interference Channels and its Applications to Medium Access Control

    Author : Arash Tahmasebi Toyserkani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; throughput; wireless sensor networks; TDMA; block fading channels; Block error rate; scheduling; ALOHA; medium access control;

    Abstract : This thesis may be distinguished into two interdependentparts. The first part outlines the outcome of our efforts toconstruct accurate and yet simple models that account for the probability of successful reception of a packet for a wide range of physical layer parameters. READ MORE

  4. 2. In-hospital bed occupancy and the emergency department - effects on decisions about the level of care

    Author : Mathias Blom; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; emergency department overcrowding; access block; inpatient admission; unplanned 72h revisits;

    Abstract : Background: Emergency Department (ED) overcrowding occurs when the need for ED services outstrips available resources. Causes have been divided into input, throughput, and output factors, of which the last appear to be the most influential. READ MORE

  5. 3. Coding for multiple-access and fading channels

    Author : Leif Wilhelmsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; Gilbert-Elliott channel model; Imperfect interleaving; Fading; Error correcting codes; Pre-coding; Channel capacity; Direct-sequence code-division multiple-access DS-CDMA ; Frequency-hopped code-division multiple-access FH-CDMA ; computer technology; Data- och systemvetenskap; Telecommunication engineering; Telekommunikationsteknik;

    Abstract : This thesis treats some information-theoretical and coding aspects of communication over multiple-access and fading channels. It consists of a general introduction and seven papers. In code-division multiple-access (CDMA) communication, many users have access to the channel simultaneously. READ MORE

  6. 4. Power Outages, Increasing Block Tariffs and Billing Knowledge

    Author : Tensay Hadush Meles; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Power outages; defensive behavior; willingness to pay; Ethiopia; generalized propensity score; Residential electricity demand; shared connections; increasing block tariff; bunching analysis; panel data; Billing knowledge; consumer behavior; non-linear electricity price; field experiment;

    Abstract : Preferences for Improved Electricity Services in Developing Countries: Household’s Defensive Behavior and Willingness to Pay Access to electricity has received much attention but its reliability has been given less focus. Thus, uninterrupted power supply remains a critical challenge facing households in low-income developing countries. READ MORE
