John and Carrie. I’m about to share with you one of the best‚ worst‚ and wildest experiences I have ever faced. It all started on a cold‚ September day‚ with it storming cats and dogs. I was in my bookshop‚ right next to the Blackleaf Lake‚ when he walked in. John was soaked from head to toe‚ and I just assumed it was from the storm. I got up off of the reading couch‚ and asked if he would like a towel and something dry to wear‚ and as I approached him I noticed what he was wearing. He looked

Matrix Generation The MIMO decoder implemented in this demo models a 4 transmit and 4 receive wireless system with BPSK modulation. The channel matrix G‚ whose elements Gij represents the amplitude distortion from the j-th transmit antenna to the i-th receive antenna‚ are real zero mean Gaussian variables with variance 1 per dimension. The channel matrix used in the demo is generated using the MATLAB® function randn() with a fixed seed initialized in the InitFcn Model callback function of the Model

6 R’s The 6 R’s are an important checklist. They are used by designers to reduce the environmental impact of products. They can also be used to evaluate the environmental impact of other products. Respect – In order to understand what it means to be a part of the solution‚ you have to begin with respect. Respect for all things: people‚ animals‚ bugs‚ birds‚ fish‚ snakes‚ rivers‚ lakes‚ oceans‚ trees‚ mountains‚ valleys and so on. Rethink — Everything on Earth is connected‚ and every decision
