Input : A set S of planar points Output : A convex hull for S Step 1: If S contains no more than five points, use exhaustive searching to find the convex hull and return. Step 2: Find a median line perpendicular to the X-axis which divides S into SL and SR SL lies to the left of SR . Step 3: Recursively construct convex hulls for SL and SR. Denote these convex hulls by Hull(SL) and Hull(SR) respectively. Step 4: Apply the merging procedure to merge Hull(SL) and Hull(SR) together to form a convex hull. Time complexity: T(n) = 2T(n/2) + O(n) = O(n log n)

Written by Microsoft software legend Juval Lowy, Programming WCF Services is the authoritative introduction to Microsoft s new, and some say revolutionary, unified platform for developing service-oriented applications [SOA] on Windows. Relentlessly practical, the book delivers insight, not documentation, to teach developers what they need to know to build the next generation of SOAs.

This book is an introduction to Ada 95. It uses an example-driven approach which gradually develops small trivial programs into large case-study type programs. The main emphasis of this book is on maintenance problems, and using object-oriented technology to write maintainable, extensible programs. Program design is introduced throughout the book, with hypothetical maintenance scenarios used to shoe design shortcomings. and revise them to accomodate maintenance needs. Practical issues such as debugging programs are tackled, and important Ada features not found in other languages are dealt with practically and early on in the text. These include exception handling, user-defined types, procedures, functions, packages and child packages.

We obtained the energy transport velocity distribution for a three dimensional ideal cloak explicitly. Near the operation frequency, the energy transport velocity has rather peculiar distribution. The velocity along a line joining the origin of the cloak is a constant, while the velocity approaches zero at the inner boundary of the cloak. A ray pointing right into the origin of the cloak will experience abrupt changes of velocities when it impinges on the inner surface of the cloak. This peculiar distribution causes long time delays for beams passing through the ideal cloak within a geometric optics description.

Microsoft Visual Basic developers have long clamored for complete objectoriented language support. Microsoft Visual Basic .NET supports all the features of an objectoriented language. In addition, the entire Microsoft .NET Framework, which includes the development support for Microsoft Windows applications, Web applications, Web services, graphics, and data access, is designed according to object-oriented principles. Developers who have a firm grasp of object-oriented principles will be the strongest .NET developers.
