2. 1. On Dynamic Spectrum Access in Cognitive Radio Networking

   Author : Said Rutabayiro Ngoga; Blekinge Tekniska Högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Cognitive Radio Networking; Dynamic Spectrum Access; Wireless Communications;

   Abstract : The exploding increase of wireless communications combined with the existing inefficient usage of the licensed spectrum gives a strong impetus to the development and standardization of cognitive radio networking and communications. In this dissertation, a framework for Dynamic Spectrum Access (DSA) is first presented, which is the enabling technology for increasing the spectral efficiency of wireless communications. READ MORE

4. 2. On the Performance Assessment of Advanced Cognitive Radio Networks

   Author : Thi My Chinh Chu; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Queueing Analysis; Cooperative Communications; Multiple-Input Multiple-Output MIMO ; Adaptive Modulation and Coding; Hybrid Interweave-Underlay Spectrum Access;

   Abstract : Due to the rapid development of wireless communications together with the inflexibility of the current spectrum allocation policy, radio spectrum becomes more and more exhausted. One of the critical challenges of wireless communication systems is to efficiently utilize the limited frequency resources to be able to support the growing demand of high data rate wireless services.

5. 3. Computerized decision support system in nursing homes

   Author : Mariann Fossum; Anna Ehrenberg; Margareta Ehnfors; Anna Forsberg; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computerized decision support; intervention study; malnutrition; nursing documentation; pressure ulcer; qualitative content analysis; think-aloud interviews; usability evaluation; Vårdvetenskap; Nursing Science;

   Abstract : The overall aim of this thesis was to study the thinking strategies and clinical reasoning processes of registered nurses (RNs) and to implement and test a computerized decision support system (CDSS) integrated into the electronic health care record (EHR) to improve patient outcomes, i.e. READ MORE

6. 4. Performance Analysis of Cognitive Radio Networks with Interference Constraints

   Author : Hung Tran; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Spectrum Underlay Access; Interference Constraints; Cognitive Cooperative Radio Networks;

   Abstract : To support the rapidly increasing number of mobile users and mobile multimedia services, and the related demands for bandwidth, wireless communication technology is facing a potentially scarcity of radio spectrum resources. However, spectrum measurement campaigns have shown that the shortage of radio spectrum is due to inefficient usage and inflexible spectrum allocation policies. READ MORE

7. 5. Prevalence, extent and severity of peri-implantitis

   Author : Christer Fransson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Peri-implantitis is a disorder that affects the tissues surrounding a functional implant. Peri-implantitis can lead to implant loss and impaired function. There is limited information regarding the prevalence of peri-implantitis. In addition the extent of the disease and pattern of bone loss are poorly described. READ MORE
