This study analyzes the demographics, criminality, and network relations of forty-one deceased Swedish foreign fighters. Our results show that most of the deceased Swedish foreign fighters were on average just under 26 years old when they died. Concerning network relations, nineteen out of the forty-one foreign fighters had at least one relationship (next-of-kin or friend) with another deceased fo

The article discusses the free speech in Yemen, and how the parties deal with this issue, that every party comments serious crimes against journalists and media institutions.

A new theorem on multivariable root-loci for transfer matrices which are not strictly proper is proved and applied to the positive real case.

The properties of combined multiplier and penalty function methods are investigated using a second-order expansion and results known for the Riccati equation. It is shown that the lower bound of the values of the penalty constant necessary to obtain a minimum is given by a certain Riccati equation. The convergence rate of a common updating rule for the multipliers is shown to be linear.

The article addresses the claims that say the former Yemeni president Ali Abdulla Saleh, who killed by Huthi rebels is a courage man because he fighted against the Huthis while he is the person who brings the Huthi from Sada, and let them took over Sanaa and the rest of the country.

The convergence properties of different updating methods for the multipliers in augmented Lagrangians are considered. It is assumed that the updating of the multipliers takes place after each line search of a quasi-Newton method. Two of the updating methods are shown to be linearly convergent locally, while a third method has superlinear convergence locally. Modifications of the algorithms to ensu

The dynamics of ethanol production/consumption in baker's yeast were studied under feed- rate controlled conditions. The yeast was grown on molasses in an 8-l fed-batch reactor and experiments were done at cell concentrations between 5 and 65 g l−1. Small changes in the feed rate were made around a feed rate corresponding to the critical growth rate, at which the yeast cell metabolism switches bet

The problem of minimal inverses for linear time invariant multivariable systems is formulated and constructively solved in a state space setting. Unknown initial states as well as zero initial states are considered. The spectrum of the minimal inverse is shown to be unique and constructable from the original system without first calculating the whole inverse. This leads to a simple way of introduc

The problem of designing a linear feedback when all state variables are not available is discussed. The design scheme is based on computation of a complete state feedback and a reduction to a specified structure. The reduction is made by approximation of the eigenspace corresponding to a set of dominant eigenvalues. The method consists of successive choices of weightings on this space. The method

Spectral analysis as well as parametric identification techniques have been applied to data from boiling water reactor noise measurements to estimate the process dynamics. Three different parametric model structures were tried. Least squares and maximum likelihood methods were tried to estimate the parameters of the models. Low order models were obtained in most cases.The results show the difficul

It is often necessary in practice to perform identification experiments on systems operating in closed loop. There has been some confusion about the possibilities of successful identification in such cases, evidently due to the fact that certain common methods then fail. A rapidly increasing literature on the problem is briefly surveyed in this paper, and an overview of a particular approach is gi
