The parabolic equation is approximated by a set of ordinary differential equations and by finite difference equations. special attention is given to the approximation of the boundary condition. Some identities suitable to check numerical calculations are also derived.

Results of simulation of the scheme for cross machine stretch estimation and prediction are given. In the simulation we use data with known statistical properties.

Utgör lokala eliter i Sverige välintegrerade sociala enheter, eller återfinns de i flera socialt åtskilda elitfraktioner? Är kvinnor inom den lokala eliten inte bara underrepresenterade till antal, utan även strukturellt missgynnade på grund av sitt kön? Och i vilken mån bidrar elitpersonernas informella umgänge, i till exempel Rotary-klubbar, till deras övergripande integration och sociala kapitaThe study applies network analysis to empirically study the integration of local elites in four Swedish municipalities. We focus particularly on the existence of elite fractions, the structural representation of women, and the role of informal ties for integration.

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
