1. 6. Product Recovery in Business Networks: An Inter-organisational Approach

   Författare :Igor Insanic; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Closed Loop Supply Chain Management; reverse logistics; industrial networks; business networks; Product recovery; classification systems.; organising;

   Sammanfattning : This doctoral dissertation analyses various ways of organising product recovery in inter-organisational networks. The purpose of product recovery is to dispose products in an environmentally responsible manner, which is strongly associated with the conservation of raw materials and sustainability. LÄS MER

3. 7. Modeling, Analysis and Design of Wireless Sensor Network Protocols

   Författare :Pangun Park; Karl Henrik Johansson; Pravin Varaiya; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Network; Markov Chain Model; Optimization; Electrical engineering; Elektroteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Wireless sensor networks (WSNs) have a tremendous potential to improve the efficiencyof many systems, for instance, in building automation and process control.Unfortunately, the current technology does not offer guaranteed energy efficiencyand reliability for closed-loop stability.

4. 8. Using Multicoloured Halftone Screens for Offset Print Quality Monitoring

   Författare :Lars Bergman; Björn Kruse; Antanas Verikas; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datorteknik; multicolour printing; printing process; colour images; colour impression; CCD-camera; Datorteknik; Computer engineering; Datorteknik;

   Sammanfattning : In the newspaper printing industry, offset is the dominating printing method and the use of multicolour printing has increased rapidly in newspapers during the last decade. The offset printing process relies on the assumption that an uniform film of ink of right thickness is transferred onto the printing areas. LÄS MER

5. 9. Identification of Stochastic Nonlinear Dynamical Models Using Estimating Functions

   Författare :Mohamed Abdalmoaty; Håkan Hjalmarsson; Adrian Wills; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction Error Method; Maximum Likelihood; Data-driven; Learning; Stochastic; Nonlinear; Dynamical Models; Non-stationary Linear Predictors; Intractable Likelihood; Latent Variable Models; Estimation; Process Disturbance; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Data-driven modeling of stochastic nonlinear systems is recognized as a very challenging problem, even when reduced to a parameter estimation problem. A main difficulty is the intractability of the likelihood function, which renders favored estimation methods, such as the maximum likelihood method, analytically intractable. LÄS MER

7. 10. Development and Verification of Dependable Software of Cyber-Physical Systems using Time-aware Computations

   Författare :Dmitrii Drozdov; Valeriy Vyatkin; Sandeep Patil; Andrei Lobov; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Abstract state machines; CPS; formal semantics; formal verification; IEC 61499; time-aware computations; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

   Sammanfattning : Wired and wireless networking is becoming a necessary part of industrial control systems’ design and is one of the reasons that required a new cyber-physical approach to modelling. The phenomenon observed in cyber-physical systems (CPS) is a variety of cross-dependencies and influences between physical processes, computational devices and communications, which needs to be taken into account at the design and verification stage.
