  1. 1. Characterization and Linearization of Multi-channel RF Power Amplifiers

    Författare :Shoaib Amin Amin; Peter Händel; Daniel Rönnow; Ulf Gustavsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The demands for high data rates and broadband wireless access require the development of wireless systems that can support wide and multi-band signals. To deploy these signals, new radio frequency (RF) front-ends are required which impose new challenges in terms of power consumption efficiency and sources of distortion e.g., nonlinearity. LÄS MER

  3. 2. Renal Klotho in mineral metabolism

    Författare :Risul Amin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Calcium and phosphorous are critical elements in a number of physiological processes, including maintenance of bone structure, cell signaling and energy metabolism. Their endocrine regulation is tightly controlled through a number of feedback mechanisms involving parathyroid hormone (PTH), vitamin D and the recently discovered fibroblast growth factor 23 (FGF23).

  4. 3. Suicidal behaviour and healthcare use among refugees

    Författare :Ridwanul Amin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Despite higher rates of mental disorders among refugees, there is limited evidence on their risk of suicidal behaviour (suicide attempt and suicide) and how such risk is influenced by differences in country-level structural factors (e.g., the national healthcare and social services, national unemployment rates etc. LÄS MER

  5. 4. Printable Green RFID Antennas for Embedded Sensors

    Författare :Yasar Amin; Hannu Tenhunen; Lirong Zheng; Qiang Chen; Leena Ukkonen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RFID; Antennas; Inkjet printing; Wideband Antennas; Narrow-band Antennas;

    Sammanfattning : In the recent years, radio-frequency identification (RFID) technology has been widely integrated into modern society applications, ranging from barcode successor to retail supply chain, remote monitoring, detection and healthcare, for instance. In general, an RFID tag or transponder is composed of an antenna and an application-specific integrated circuit chip. LÄS MER

  7. 5. Local measures for probabilistic networks

    Författare :Amin Kaveh; Matteo Magnani; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Modeling and analysis of imperfection in network data is essential in many applications such as protein–protein interaction networks, ad-hoc networks and social influence networks. In the study of imperfect network data, three issues have to be considered: first the type of imperfection, second the aspects of networks such as existence of nodes/edges or attributes of nodes/edges in which imperfection occurs and third the theory that has been used to represent imperfection.
