  1. 1. Design-based sampling methods for environmental monitoring

    Författare :Xin Zhao; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Efficient strategies for environmental monitoring are proposed with an emphasis on the importance of using available information. In environmental monitoring, it is common to use area frames covering the assumed spread of the population of inter-est. LÄS MER

  3. 2. Language-based Approaches to Safe and Efficient Distributed Programming

    Författare :Xin Zhao; Philipp Haller; Roberto Guanciale; Wolfgang De Meuter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Programming languages; Distributed systems; Type system; Replicated data types; Computer Science; Datalogi;

    Sammanfattning : Distributed systems address the increasing demand for fast access to resources and fault tolerance for data. Strong consistency ensures that all clients observe consistent data updates atomically on all servers in a distributed system, and it is widely used in systems such as relational databases. LÄS MER

  5. 4. Aero Engine Intercooling

    Författare :Xin Zhao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PIV; CFD; porous media; aero engine; pressure measurements; intercooling control; system performance; intercooler; variable flow path;

    Sammanfattning : Intercooling has the potential to provide a shortcut to the next generation aero engines with higher bypass ratio (BPR), higher overall pressure ratio (OPR) and higher turbine inlet temperature (TIT) by lowering the high pressure compressor (HPC) delivery temperature. To be able to establish a systematic understanding of aero engine intercooling, the heat transfer and pressure loss characteristics of a given intercooler architecture need to be known in the parameter range anticipated for the engine optimization.

  7. 5. On Aero Engine Intercooling

    Författare :Xin Zhao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aero engine; CFD; porous media; coolant flow control; system performance; intercooler;

    Sammanfattning : Establishing an optimal intercooled aero engine constitutes a coupled problem where the conceptual design of the intercooler and the engine has to be considered simultaneously. The heat transfer and pressure loss characteristics will depend on the choice of the intercooler architecture. LÄS MER
