This paper overviews new methods for fast correlation attacks on stream ciphers, based on convolutional codes. Identification of embedded structures of concatenated convolutional codes (both parallel and serial) in the shift register code, providing increased performance, is considered.

This paper reviews friction phenomena and friction models of interest for automatic control. Particular emphasis is given to two recently developed dynamic friction models, the Bliman-Sorine model and the LuGre model. These models capture many frictional phenomena observed in laboratory experiments. The behaviors of the models in different situations are discussed in detail. Methods for friction c

MAX-lab is a national laboratory operated jointly by the Swedish Research Council and Lund University. Nowadays it consists of three storage rings and one electron pre-accelerator. Due to the improvement of nanotechnology, a new storage ring is needed. Hence, MAX IV will be 100 times more efficient than already existing synchrotron radiation facilities, becoming a leading facility for studies of p

The material model consists of a viscoelastic Burgers element and an additional viscoplastic element, which includes Bingham viscosity and a viscoplastic Kelvin element. For spherical and cylindrical cavities, expressions are derived for the stress and strain fields and volume convergence. Spherical and cylindrical cavities are treated in a unified formulation. The expressions for the transient ph

Thread Level Speculation (TLS) has been suggested as a mean to automatically (or semi-automatically) extract parallelism from sequential programs. While there have been multiple attempts both in hardware and software to implement real time TLS, to the best of our knowledge all attempts have so far been on a byte code level or with statically typed languages. In this study, we examine the potential

This paper is basically a brief compare and contrast study regarding two different lines of development with regard to the European film and television production sector which has taken place in Europe during the last three decades. On the one hand it examines and evaluates the phenomenon that is the rampant rise of runaway production of international film and television and which has predominantl

In this paper, an extension of Modelica, entitled Optimica, is presented. Optimica extends Modelica with language constructs that enable formulation of dynamic optimization problems based on Modelica models. There are several important design problems that can be addressed by means of dynamic optimization, in a wide range of domains. Examples include, minimum-time problems, parameter estimation pr
