1. 1. Balancing Demand and Supply in Complex Manufacturing Operations: Tactical-Level Planning Processes

   Författare :Hafez Shurrab; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; complexity; organizational information processing; configure-to-order; order fulfillment; engineer-to-order; sales and operations planning; material delivery scheduling; tactical planning;

   Sammanfattning : By balancing medium-term demand and supply, tactical planning enables manufacturing firms to realize strategic, long-term business objectives. However, such balancing in engineer-to-order (ETO) and configured-to-order (CTO) operations, due to the constant pressure of substantial complexity (e.g. LÄS MER

3. 2. The Meaning of Environmental Management : An Interpretive Study of Managing Emergent or Evolutionary Environmental and Energy Strategy

4. 3. Varför etiska kommittéer?

   Författare :David Hoff; Rättssociologiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; professional ethics; reducing complexity; normative expectations; norms; legitimacy; morals; ethics; ethical steerage; social steerage; ethics committees; social control unit; civic morals; Stjernquist; Luhmann; Durkheim; Sociology; Sociologi;

   Sammanfattning : This thesis analyses the development of ethics committees from a sociology of law perspective and a social steerage perspective ("social control"). The main question is: Why are ethics committees established? Institutionalised ethics committee is a rather new phenomenon, which has become widely spread in the last 20 years. LÄS MER

5. 4. Methods for Reducing the Complexity of Geometrical Structures Based on CFD Programming : Time Efficient Simulations Based on Volume Forces Coupled with Single and Two-phase Flow

   Författare :Kamal Rezk; Lars Nilsson; Jonas Berghel; Erik Dahlquist; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical design cycle; CFD; porous media; volume forces; heat exchanger; vacuum dewatering; time efficient simulations; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : Throughout recent years, computer based programs have been applied to solve and analyse industrial problems encountered global fields such as automobile design for reduction of CO2-gas, designing wind parks aimed at increasing power output etc. One of these developed programs is Computational Fluid Dynamics (CFD) which numerically solves complex flow behaviour based on computer power.

7. 5. Reducing Memory Traffic with Approximate Compression

   Författare :Albin Eldstål-Ahrens; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory Compression; Memory Systems; Compression; Computer Architecture; Lossy Compression; Approximate Computing;

   Sammanfattning : Memory bandwidth is a critical resource in modern systems and has an increasing demand. The large number of on-chip cores and specialized accelerators improves the potential processing throughput but also calls for higher data rates. In addition, new emerging data-intensive applications further increase memory traffic. LÄS MER
