  1. 1. Essays on Multi-Level and Multi-Item Inventory Control

    Författare :Rolf Forsberg; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lot sizing policy; joint replenishment; coordinated replenishment; compound Poisson demand; Poisson demand; stochastic model; multi-echelon; multi-item; ordering policy; Transport technology; Transportteknik;

    Sammanfattning : In many companies and organisations the planning and control of purchasing, production, inventory and transportation is of great importance. In a manufacturing industry it is not unusual that the value of the total stock of end products and parts in production is larger than the value of the production system itself with its machines and factory buildings.

    Sammanfattning : Antibiotic resistance is an escalating problem, not only due to less desirable treatment options and outcome, but also due to the economic burden to health care caused by resistant pathogens. Since the process of developing new antibiotics is slow, we need to carefully consider the usage of the antibiotics still available. LÄS MER

  3. 3. Nonlinear modeling of reinforced dowel joints in timber structures : a combined experimental-numerical study

    Detta är en avhandling från Vienna : Vienna University of Technology

    Författare :Michael Schweigler; Josef Eberhardsteiner; Thomas K. Bader; Thierry Descamps; [2018]

    Sammanfattning : Steel dowels are indispensable elements for the design of joints in modern timber structures. Dowels are broadly used because of their flexibility in design and easy assembling on-site, as well as due to their advantageous mechanical behavior. LÄS MER

  4. 4. Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models

    Detta är en avhandling från Lunds tekniska högskola, Institutionen för värme- och kraftteknik

    Författare :Munir Khan; Jinliang Yuan; Bengt Sundén; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical analysis; multi-scale; multi-phase; reacting flows; multi-component;

    Sammanfattning : A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance.
