In this paper we address the problem of Internet networks optimization using a mixed Open Shortest Path First (OSPF) and Multi Protocol Label Switching (MPLS) routing. Since MPLS can be combined with any routing protocol there appeared an idea of coupling IP streams routed via OSPF protocol and MPLS Label Switched Paths (LSPs) in the same network. One expected advantage behind such a combined rout
In this paper we consider control signal properties, such as maximum magnitude and activity, as well as system robustness measures. We derive an ideal controller and control signal for exponential disturbance rejection for a first order process with time delay. For the resulting closed-loop system, it is shown analytically that there are strong interconnections between robustness measures and cont
Vision sensors are of increasing interest for non-destructive, remote measurements in industrial as well as consumer products. Their operation is based on intelligent techniques for image understanding, followed by robust quantification of the detected phenomenon. A well-known application area is movement detection and isolation. This paper discusses how movement can be detected and quantified by
The internet has had an impact on public relations that goes well beyond significant adjustments in practice made in response to technological change. Mirroring the emergence of ”Web 2.0” platforms, the discipline is increasingly articulating its purpose and culture through discourse associated with social media. Concepts such as transparency, authenticity, conversation and engagement can be inext
Nested convolutional codes are a set of convolutional codes that is derived from a given generator matrix. The structural properties of nested generator matrices and nested convolutional codes are studied. A method to construct the set of all (rational) minimal generator matrices of a given convolutional code is presented. Nested convolutional codes derived from equivalent minimal generator matric
A hot potato: food and meals in families with small children and teenagers. Introduction, with aims and hypothesis The project ‘Konsumenters problemlösningar på livsmedelsmarknadens nya arenor. Matinspiration under tidspress’ [‘Consumers’ problem-solving/solution to the food market’s new arenas: food inspiration against the clock’] initially addressed the following issue: shopping for food and p
In this paper propagation of transient electromagnetic waves in a reciprocal bi-isotropic medium is presented. The constitutive relations are convolution integrals with two susceptibility kernels that model the medium. The propagation problem is solved by the introduction of a wave-splitting technique. This wave-splitting is used to solve the propagation problem using either an imbedding approach
There are significant differences between the anointing episodes in Luke 7:36-50 and in John 12:1-8, and the relation between them has been much debated. I propose that the episodes testify to a similar Christological emphasis as well as a different one which may indicate that one or both evangelists were aware of the work of the other. There is reason to assume that the Lukan as well as the Johan
Numerous recent studies have proven that traffic patterns generated by multimedia services are different from traditional Poisson traffic. It has been shown that multimedia network traffic exhibits long-range dependency (LRD) and self-similar characteristics. The area of wireless IP traffic modeling in terms of providing assured QoS to the end-user is still immature and the majority of existing wo
Popular Abstract in English In the past ten years, homogeneous charge compression ignition (HCCI) combustion has been one of the subjects receiving great research interests in the combustion research community and the engine industry. This is because HCCI combustion processes have the potential of not only capable providing high efficiency like diesel engine combustion, but also producing much lowLarge Eddy Simulation (LES) modeling is developed to study homogeneous charge compression ignition (HCCI) combustion under different engine operation and mixture conditions, including real engine configurations and generic test cases. A previously developed HCCI model has been validated by comparing the simulation results with engine experiments. A new spark-assisted HCCI (SACI) combustion model h
The RUNES project defines a complex road tunnel scenario involving multiple mobile robots navigating in sensor network environment. In this paper, a TrueTime simulation model of the tunnel scenario is developed. The TrueTime simulator allows concurrent simulation of the physical robots and their environment, the software in the nodes, the radio communication, the network routing, and the ultra-sou
