    Sammanfattning : The requirements for next-generation wireless communications networks, particularly fifth-generation (5G) and beyond, are driven by at least three broad use cases. These include enhanced mobile broadband services to support extremely high data rates in terms of network or per user in both uplink and downlink, massive machine-type communications to accommodate massive internet-of-things applications, and critical machine-type communications to handle mission-critical applications that require ultra-high reliability and low latency.

  3. 2. Fighter Aircraft Maneuver Limiting Using MPC : Theory and Application

    Författare :Daniel Simon; Johan Löfberg; Torkel Glad; Jan Maciejowski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model predictive control; flight control;

    Sammanfattning : Flight control design for modern fighter aircraft is a challenging task. Aircraft are dynamical systems, which naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. LÄS MER

  4. 3. On understanding of external and internal integration in supply chains : challenges and evaluation

    Författare :Hana Hulthén; Dag Näslund; Andreas Norrman; Patrik Jonsson; Teknisk logistik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Supply chain integration; contextual factors; sales and operations planning process; S OP process; performance measures; Logistics; Logistik; Supply Chain Integration; contextual factors; Sales and Operations planning process; S OP process; Performance measures;

    Sammanfattning : Benefits of implementing Supply Chain Integration (SCI) are acknowledged in existing integration literature. Integration extending beyond functional silos and firm boundaries is expected to provide value for customers in terms of higher quality, improved service level, and reduced costs. LÄS MER

  5. 4. Reconstruction planning in post-conflict zones : Bosnia and Herzegovina and the international community

    Sammanfattning : The history of mankind has been plagued by an almost continuous chain of various armed conflicts - local, regional, national and global - that have caused horrendous damage to the social and physical fabric of cities. The tragedy of millions deprived by war still continues. LÄS MER

  7. 5. Stereophonic Acoustic Echo Cancellation: Theory and Implementation

    Författare :Peter Eneroth; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stereophonic Acoustic Echo Cancellation; Filterbank; Two-Channel Fast RLS; Two-Channel Frequency-Domain Adaptive filtering; NLMS; Electronics and Electrical technology; Audio Coding; Elektronik och elektroteknik; Signal processing; Signalbehandling; Subband;

    Sammanfattning : The thesis treats theory and implementation aspects for stereophonic acoustic echo cancellation. In Paper I a complete implementation of a stereophonic acoustic echo canceler based on the two-channel fast recursive least-squares algorithm is presented. LÄS MER
