1. 1. Reliable and deterministic network services

   Författare :Florian-Daniel Otel; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; queuing delay guarantees; service curve; constraint-based routing; TCP; network security; arrival curve; network failure recovery; traffic engineering; network calculus; traffic envelope;

   Sammanfattning : In a post Internet bubble economic environment the obvious lack of any disruptive new technologies that could give new impetus to network growth (as, for example, experienced after the appearance of the Web) lead to a trivialization of network services: Aside grass-roots, semi-subterranean applications like file sharing, entertainment content swapping and on-line gaming, it can be argued that network services are presently used in a manner not very different than a decade ago. In this respect, one of the factors that can be identified as limiting further development is the perceived lack of guarantees with regard to network services. LÄS MER

3. 2. An electronic warfare perspective on time difference of arrival estimation subject to radio receiver imperfections

   Författare :Johan Falk; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

   Sammanfattning : In order to ensure secure communication in digital military radio systems, multiple methods are used to protect the transmission from being intercepted by enemy electronic warfare systems. An intercepted transmission can be used to estimate several parameters of the transmitted signal such as its origin (position or direction) and of course the transmitted message itself. LÄS MER

4. 3. Essays on Microeconometrics and Immigrant Assimilation

   Författare :Alpaslan Akay; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Average marginal effect; Marginal effect of the average individual; Employment and earnings assimilation; Quasi-fixed effects approach; Initial value problem; Dynamic censored random-effects model; Monte Carlo experiment; Heckman’s approximation; Simple method of Wooldridge; Dynamic random-effects sample-selection model; wage-curve method;

   Sammanfattning : Paper I. Asymptotic bias reduction for a conditional marginal effects estimator in sam- ple selection models. In this article we discuss the di¤erences between the average marginal effect and the mar- ginal effect of the average individual in sample selection models, estimated by the Heck- man procedure.

5. 4. Model-Based Hypothesis Testing in Biomedicine : How Systems Biology Can Drive the Growth of Scientific Knowledge

   Författare :Rikard Johansson; Gunnar Cedersund; Tomas Strömberg; Peter Strålfors; Marija Cvijovic; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems biology; modeling; ODE; hypothesis testing; falsificationism; insulin signaling; yeast; population heterogeneity; cell-to-cell variation; facilitation; pyramidal; synaptic; bootstrapping; personalized medicine; omics;

   Sammanfattning : The utilization of mathematical tools within biology and medicine has traditionally been less widespread compared to other hard sciences, such as physics and chemistry. However, an increased need for tools such as data processing, bioinformatics, statistics, and mathematical modeling, have emerged due to advancements during the last decades. LÄS MER

7. 5. Strategies to improve outcome in patients with ST elevation myocardial infarction treated with primary PCI

   Författare :Tim Tödt; Eva Swahn; Jan Engvall; Magnus Janzon; Stefan James; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Background: ST elevation myocardial infarction (STEMI) caused by a ruptured atherosclerotic plaque with overlying thrombosis leads to ischemia and progressively to the death of the myocardial cells supplied by the affected coronary artery. Rapid reperfusion with primary Percutaneous Coronary Intervention (PCI) in an experienced centre is the preferred therapy for these patients. LÄS MER
