  1. 1. Multiple-Input Multiple-Output Radio Propagation Channels Characteristics and Models

    Detta är en avhandling från Royal Institute of Technology (KTH)

    Författare :Kai Yu; KTH.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signalbehandling; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Sammanfattning : In recent years, deploying multiple antennas at both transmitter and receiver has appeared as a very promising technology. By exploiting the spatial domain, multiple-input multiple-output (MIMO) systems can support extremely high data rates as long as the environments can provide sufficiently rich scattering. LÄS MER

  2. 2. Models and meaning on management models and systems of meaning when implementing change

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jacob Hallencreutz; Luleå tekniska universitet.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Sammanfattning : Change has become a vital business partner for many organizations. Survival of most organizations depends on their ability to implement adequate changes to support the organization. This thesis deals with questions about measurement systems, process based system models and organizational change with a specific focus on implementation challenges. LÄS MER

  3. 3. Adaptive Forgetting through Multiple Models and Adaptive Control of Car Dynamics

    Detta är en avhandling från Linköping : Linköping University

    Författare :Peter Andersson; Linköpings universitet.; Linköpings universitet.; [1983]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive forgetting; Multiple models; Adaptive control; Car dynamics;

    Sammanfattning : A new recursive identif ication method, Adaptive Forgetting through Multiple Models - AFMM, is presented and evaluated using computer simulations. AFMM is specif ically suited for identification of systems with jumping or rapidly changing parameters. LÄS MER

  4. 4. Modeling and Segmentation using Multiple Models

    Detta är en avhandling från Linköping : Linköping University

    Författare :Predrag Pucar; Linköpings universitet.; Linköpings universitet.; [1995]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An established area within the system identification field is identification of linear models. In practice, sometimes the performance of such models is not satisfactory and non-linear models are needed. This thesis is devoted to modeling and identification of systems by means of multiple models. LÄS MER

  5. 5. Longitudinal Models for Quantifying Disease and Therapeutic Response in Multiple Sclerosis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ana M. Novakovic; Uppsala universitet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nonlinear mixed-effects models; pharmacometrics; NONMEM; multiple sclerosis; cladribine; EDSS; item response theory; relapse rate; absolute lymphocyte count; total volume T2 lesions; burden of disease; power; sample size; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Treatment of patients with multiple sclerosis (MS) and development of new therapies have been challenging due to the disease complexity and slow progression, and the limited sensitivity of available clinical outcomes. Modeling and simulation has become an increasingly important component in drug development and in post-marketing optimization of use of medication. LÄS MER
