The multi-layered and multilevel use of bibliometric measures in Swedish universities: Isomorphism, translation and strategic choice

In recent years, systems for resource allocation in academic research based on performance indicators have been introduced in many European countries (Hicks, 2012). Today, we are at a point where the use of bibliometrics based indicators for research evaluation and resource allocation more or less permeates academic systems on all levels and across the world. The implementation—and the effects of

On the complexity of column generation in survivable network design with path-based survivability mechanisms

This paper deals with path-based linear programming formulations in survivable network design. In a recent survey we have investigated the complexity of the column generation problems for a large variety of protection and restoration mechanisms in a single or multiple link failure scenario, and classified them according to their structure. It turned out that all the considered column generation pr

Heuristics for Handling Direct Upstream Demand in Two-Echelon Distribution Inventory Systems

This paper considers a two-echelon distribution inventory system with a central warehouse and a number of retailers. There is direct customer demand also at the warehouse. If this upstream demand requires a high service, it may be advantageous to give higher priority to customer orders compared to retailer replenishments. We suggest and evaluate techniques for handling this situation. One techniqu

Direct and inverse scattering for transient electromagnetic waves in nonlinear media

Nonlinear propagation of electromagnetic waves is an important problem in optics. Often the properties of the nonlinear media are not fully understood. The solution of an inverse problem can provide an aid to that understanding. An inverse transmission problem is posed, it is one of reconstructing the medium parameters, by measurement of a wave that has been propagated through the nonlinear medium
