An Engineering Penetration/Perforation Model of Hemispherical Nosed Rigid Cylindrical Rods into Strain-hardening Targets
A four-stage model of the penetration/perforation by hemispherical-nosed rigid cylindrical rods into targets whose materials exhibit strain-hardening effects. During each stage of the penetration process, a kinematically admissible velocity field involving one or more unknown parameters is assumed. These parameters are determined by minimizing the rate of plastic dissipation. From this velocity field, the incremental deformations of the target, the penetration depth, the resisting force acting on the penetrator and hence its deceleration are evaluated. We propose a criterion for the formation and ejection of the cylindrical plug in the target and use it to study problems involving the perforation of the target. Computed results for the exit speed of the penetrator and, when the targets are not perforated, of the penetration depth are found to match well with the corresponding test values.

Migrating Oracle Database 10 G from Sun Servers to Dell Servers
T o improve the process of migrating data from one database to another or from one platform to another, two key Oracle tools for data migration Data Pump and Transportable Tablespaces were enhanced in Oracle Database 10 g . Data Pump is an improved version of the Oracle Import and Oracle Export utilities from previous versions of Oracle Database. The improvements are designed to add capabilities and decrease the time required for exporting and importing Oracle Database 10 g data.

Tutorial: Introduction to MATLAB
This short tutorial will only describe a fraction of the functions available in MAT- LAB, and not all of the options available for the commands will be described. The easiest way to find more information about a command is to type help com- mandattheMATLAB prompt, and some information will be shown in the MAT- LAB window. If you typehelpwin command, a separate window will open instead.

Performance Management as a Business Process
When treated as a business process, a performance management system can transform an organization's culture, creating and sustaining a high performing, innovative workplace. The most effective organizations view performance management as a full business process that effectively integrates science, tools and processes. Similar to implementing a new supply chain, every component must be aligned and work effectively for the system to function successfully.
