  1. 36. Digital Predistortion for the Linearization of Power Amplifiers

    Författare :Jessica Chani Cahuana; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; behavioral model; Volterra series; nonlinear; digital predistortion; Doherty power amplifier; power amplifier; efficiency;

    Sammanfattning : High efficiency and linearity are indispensable requirements of power amplifiers. Unfortunately they are difficult to obtain simultaneously, since high efficiency PAs are nonlinear and linear PAs may have low efficiency. LÄS MER

  3. 37. Real-time Locating Systems for indoor applications : the methodological customization approach

    Författare :Bartosz Jachimczyk; Wlodek Kulesza; Alfonso Bahillo Martínez; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accuracy and Precision; Angle of Arrival; Fingerprinting Method; Indoor Localization; Indoor Positioning System; Multi-Sensor System; Neural Network; Radio Frequency Identification - RFID; Real Time Locating System; Received Signal Strength; RFID Network Planning; Scene Analysis; Sensors Arrangement; System Customization; Uncertainty; Uncertainty Map; User Driven Design;

    Sammanfattning : Emerging wireless technologies increase the potential and effectiveness of wireless Real-time Locating Systems (RTLSs), which precisely localize the position, and identify things and people in real time. Among many applications, RTLSs are widely used in the industrial sector for indoor logistics and safety applications. LÄS MER

  4. 38. Prognostic and treatment predictive factors for radio- and chemotherapy resistance in breast cancer patients- a step towards personlized medicine

    Författare :Emma Niméus; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 2-DE; cyclin B1; breast cancer; radioresistance; immunohistochemistry; chemotherapy resistance; gene expression; treatment prediction; prognosis;

    Sammanfattning : Breast cancer is the most common cancer form among women in the Western world. Although treatment has improved during the last decades, there is still a significant proportion of the patients who are not cured. LÄS MER

  5. 39. A Triple Helix of Learning Processes - How to cultivate learning, communication and collaboration among distance-education learners

    Författare :Eva Rydberg Fåhraeus; KTH; []
    Nyckelord :Distance education; collaborative learning; Computer-supported collaborative learning; CSCL; information and communication technology; ICT; forum system; learning processes;

    Sammanfattning : This work focuses on collaborative learning and how it canbe applied and supported in distance education. Previous workindi-cates that distance learners experience more loneliness,technical problems and lack of stimulation than face-to-facelearners do. Collaboration with peers may improve the feelingof connectedness and engagement. LÄS MER
