2. 1. Public Health Programmes, Healthcare and Child Health

   Author : Daniel Knutsson; Per Pettersson-Lidbom; Mårten Palme; Sonia Bhalotra; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public Health; Mortality; Infant Mortality; Piped Water; Well-visits; Crowding; Delivery Care; Sulfa; Information; Clean Water; Neonatal Mortality; Economics; nationalekonomi;

   Abstract : This thesis consists of three self-contained chapters.Modern Medicine, Public Policy and Infant Health: Evidence from a Preventive Health Programme in Sweden. This paper explores a universal preventive health programme targeting infants that coincided in time with the introduction and availability of an early antibiotic, sulfa. READ MORE

4. 2. Emergency Department Crowding. Objective Modelling based on Workload

   Author : Jens Wretborn; Lund Medicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Crowding; Emergency Department; Overcrowding; Arbetsbelastning; Akutmottagning; Akutsjukvård; Belastning;

   Abstract : Emergency Departments (ED) have a central role in modern healthcare, providing emergent care regardless of complaint 24/7. However, EDs are often characterized by long waiting times for patients and a stressful working environment for staff. These are features or a resource and demand mismatch, internationally known as ED crowding. READ MORE

5. 3. Modelling of Terahertz Planar Schottky Diodes

   Author : Aik-Yean Tang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; S-parameter extraction; Electro-thermal; Schottky diodes; Skin effect; Electromagnetic; Frequency multipliers; High-power frequency multiplier; Current crowding; Proximity effect; Submillimetre wave generation and detection; Geometric modelling; Gallium Arsenide;

   Abstract : This thesis deals with the modelling of THz planar Schottky diodes, focusing on analyses of the geometry- dependent parasitics and the diode chip thermal management. Moving towards higher operating frequencies, the electromagnetic couplings pose significant limitations on the diode performance. READ MORE

6. 4. Millimeter-Wave Impulse Radio

   Author : Mats Ärlelid; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compound semiconductor; resonant tunneling diode; ultra wideband; 60 GHz; on-off keying; transmitter; receiver; and super-regenerative oscillator;

   Abstract : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. READ MORE

7. 5. Public transport demand and supply management under uneven passenger distributions

   Author : Soumela Peftitsi; Erik Jenelius; Oded Cats; Achille Fonzone; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; public transport; uneven passenger distribution; transit assignment model; travel behavior; control measures; crowding information; skip-stop; Transportsystem; Transport Systems;

   Abstract : Overcrowding in public transport (also known as public transportation, public transit, or transit) systems due to increased travel mobility has become a major problem for public transport operators. Overcrowded transit stations and vehicles are connected to travel time variability and greater discomfort for the passengers. READ MORE
