\"image\"<\/a> <\/td>\nProject Name: <\/strong>ImageColorizer
Languages:<\/strong> C#, Visual Basic
Description:<\/strong> This application manipulates an image by converting the majority of the image to grayscale, except for portions of the image containing user-selected hues.<\/td>\n<\/tr>\n
\"image\"<\/a> <\/td>\nProject Name: <\/strong>LINQRayTracer
Languages:<\/strong> C#, Visual Basic
Description:<\/strong> Based on Luke Hoban<\/a>\u2019s LINQ implementation of a ray tracer, this application parallelizes a computationally intensive LINQ query using PLINQ.<\/td>\n<\/tr>\n
\"image\"<\/a> <\/td>\nProject Name: <\/strong>MandelbrotFractals
Languages:<\/strong> C#, C++\/CLI
Description:<\/strong> This application provides an implementation of the classic Mandelbrot<\/a> fractal, parallelizing the processing of the fractal using the Parallel class.<\/td>\n<\/tr>\n
\"image\"<\/a> <\/td>\nProject Name: <\/strong>Morph
Languages:<\/strong> C#
Description:<\/strong> Implements a morphing<\/a> algorithm between two images.  Parallelization is done using the Parallel class.<\/td>\n<\/tr>\n
\"image\"<\/a> <\/td>\nProject Name: <\/strong>NBodySimulation
Languages:<\/strong> C#, F#
Description:<\/strong> Implements a classic n-body simulation using C# and WPF for the UI and using F# for the core computation. Parallelism is achieved using the Parallel class. <\/td>\n<\/tr>\n
\"image\"<\/a> <\/td>\nProject Name: <\/strong>NQueens
Languages:<\/strong> C#, Visual Basic
Description:<\/strong> This application implements a solution to the N-Queens<\/a> problem, using both LINQ and PLINQ.<\/td>\n<\/tr>\n
