Reinforced Mixed Mode Bending Apparatus
Background Fracture toughness tests measure the ability of a material to resist propagation of a pre-existing flaw. This is an important material property in the manufacturing industry, since the avoidance of all flaws is not possible. Mixed Mode Bending (MMB) is a previously developed fixture that investigates the fracture toughness of layered materials...

Binary Neural Network for Improved Accuracy and Defense Against Bit-Flip Attacks
­Recently, Deep Neural Networks (DNNs) have been deployed in many safety-critical applications. The security of DNN models can be compromised by adversarial input examples, where the adversary maliciously crafts and adds input noise to fool a DNN model. The perturbation of model parameters (e.g., weight) is another security concern, one that relates...
