mkdosfs - Make DOS file system utilty. I wrote this, partially to complement the dosfsck utility written by Werner Almesberger (who graciously gave me some pointers when I asked for some advice about writing this code), and also to avoid me having to boot DOS just to create data partitions (I use Linux to back up DOS :-) ).

Need to make sense of the many changes to Visual Basic for the new .NET platform? VB .NET Language in a Nutshell introduces the important aspects of the language and explains the .NET framework. An alphabetical reference covers the functions, statements, directives, objects, and object members that make up the VB .NET language. To ease the transition, each language element includes a "VB .NET/VB 6 Differences" section.

Windows applications using C++ and the Microsoft Foundation Class (MFC) library. The text builds from the ground up, first describing the Windows architecture and showing how MFC works with that architecture next covering the document/view framework that simplifies the creation of industrial-strength programs and finally illustrating advanced concepts like the usage of dynamic link libraries (DLL), creating Internet clients, and building form-based applications.

A cylindrical wave expansion method is developed to obtain the scattering field for an ideal two-dimensional cylindrical invisibility cloak. A near-ideal model of the invisibility cloak is set up to solve the boundary problem at the inner boundary of the cloak shell. We confirm that a cloak with the ideal material parameters is a perfect invisibility cloak by systematically studying the change of the scattering coefficients from the near-ideal case to the ideal one. However, due to the slow convergence of the zeroth order scattering coefficients, a tiny perturbation on the cloak would induce a noticeable field scattering and penetration.

We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking fields, so that the anisotropy ratio tends to infinity, the D and B fields blow up near the cloaking surface. Since the metamaterials used to implement cloaking are based on effective medium theory, the resulting large variation in D and B will pose a challenge to the suitability of the field averaged characterization of " and 碌. We also consider cloaking with and without the SHS (softand- hard surface) lining, shown in [6] to be theoretically necessary for cloaking in the cylindrical geometry. We demonstrate numerically that cloaking is significantly improved by the SHS lining, with both the far field of the scattered wave significantly reduced and the blow up of D and B prevented.

DESCRIPTION The DCP0105 family is a series of high efficiency, 5V input isolated DC/DC converters. In addition to 1W nominal galvanically isolated output power capability, the range of DC/DCs are also fully synchronizable. The devices feature thermal shutdown, and overload protection is implemented via watchdog circuitry. Advanced power-on reset techniques give superior reset performance and the devices will start into any capacitive load up to full power output. The DCP0105 family is implemented in standard- molded IC packaging, giving outlines suitable for high volume assembly.
