Efficient Implementation of the IAA-based Magnitude Squared Coherence Estimator

Recently, a novel Magnitude Squared Coherence (MSC) estimator was proposed using the Iterative Adaptive Approach (IAA) algorithm. In this paper, we present a computationally efficient implementation of this estimator, exploiting the inherently low displacement rank of the necessary products of Toeplitz-like matrices, thereby allowing for the development of appropriate Gohberg-Semencul (GS) represe

Potential Risk Handling Alternatives for Supply Chain Disruptions in Liquid Food Production – the case of V&S Vin & Sprit AB, the Sundsvall site

V&S Sundsvall (a part of V&S Vin & Sprit AB) is a Swedish company producing different alcoholic beverages, mainly for the Swedish market. The company has lately paid increasing attention to supply chain disruption risk issues. In another study, one of the authors (Paulsson 2007) developed a model, called the DRISC (Disruption Risks In Supply Chains) model, for the structuring, evaluati

Ändrade rutiner. Hushåll, samhälle och avfallsproblem

I detta kapitel studeras något så oglamoröst som hur människor hanterar sitt hushållsavfall i vardagliga situationer, de problem växande sopberg leder till och hur samlade nationella och internationella processer leder till politiska beslut, målsättningar och åtgärder som för med sig att aktörer på skilda nivåer ända ner till den enskilda hushållsmedlemmen måste ändra sitt beteende och delta i sam

Experimental Study of the Minimum Chip Thickness during the Machining of Duplex Stainless Steel

During a machining operation the workpiece material at some point has to split up into two separate material flows forming the chip and machined surface respectively. In the boundary zone between these two different flows of material it is possible to distinguish a stagnation point. This stagnation point is closely related to the minimum chip thickness h1min. The size of h1min is of great interest
