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

Joseph Roth was a wanderer. Born in a Galizian shtetl, in the periphery of the Danube Monarchy, he went to Vienna, Berlin, and Paris, became socialist, monarchist, European, cosmopolitan. And yet remained East European Jew. Relentlessly on the move, and the embodiment of a Jewish and a modern destiny, Roth travelled through Europe and lived and wrote his novels and feuilletons in hotels and cafés,

Full-cycle simulations of a spark ignition engine running on a primary reference fuel have been performed using a two-zone model. A detailed kinetic mechanism is taken into account in each of the zones, while the propagating flame front is calculated from a Wiebe function. The initial conditions for the unburned gas zone were calculated as a mixture of fresh gas and rest gas. The composition of th
