Introduction,ction of the variables x, y,..., u, u., u., u.,... Only a finite number of derivatives shall occur. Needless to say, a function u(x, y,...) is said to be a solution of (1), if in some region of the space of its independent variables, the function and its derivatives satisfy the equation identically

The Single First Order Equation,e of two independent variables, but it will be made clear that the theory can be extended immediately to any number of variables. We consider then equations of the form . where we have used the notation u. = p, u. = q. A solution z = u(x, y), when interpreted as a surface in three dimensional space,

Paketfilter- und Tunnelkonfiguration zur Firewall-verträglichen Mobilitätsunterstützung in IP-Netzent mit Firewalls. Damit der Ansatz von Mobile IP auch in Firewall-geschützten Netzen eingesetzt werden kann, wurde die Architektur FATIMA entwickelt, in welcher ein mobilitätsunterstützendes Gateway in die Firewall eines Netzes integriert wird. Der vorliegende Artikel befasst sich speziell mit den Au

Purple Acid Phosphatases (PAPs): Molecular Regulation and Diverse Physiological Roles in Plants,es. PAPs exist as a multigene family in nearly all plant species and have been widely characterized for their roles in tolerance to phosphate (Pi) deficiency. PAPs are majorly involved in Pi uptake and recycling, thus influencing Pi acquisition and utilization efficiency of plants. Posttranscription

Portfolio Optimization Using SPEA2 with Resampling,n practice, resulted being very poor. In this paper we suggest that using a resampling mechanism may filter out the most unstable. We test this idea on real data using SPEA2 as optimization algorithm and the results show that the use of resampling increases significantly the reliability of the resulting portfolios.
