This paper describes a system developed to assist in model-based training of minimally invasive, laparoscopic procedures. The key factor motivating the development of the device called CAST (Computer-Assisted Surgical Trainer) is the need to improve the state-of-the-art in teaching laparoscopy, and ultimately achieve better surgical outcomes. CAST's design(More)
Predicting the popularity of items in rating networks is an interesting but challenging problem. This is especially so when an item has first appeared and has received very few ratings. In this paper, we propose a novel approach to predicting the future popularity of new items in rating networks, defining a new bipartite clustering coefficient to predict(More)
Neuropathic arthropathy (Charcot joints) most frequently affect the weight-bearing joints of the body, are commonly associated with a variety of medical and neurological conditions and are notoriously difficult to treat due to the nature of the underlying pathology. We present a case of ipsilateral shoulder and thumb carpometacarpal (CMC) joint neuropathic(More)

CASE REPORT We present a case of a 21 year old male who presented with a swelling of the right inguinal region which was gradually progressive. Radiologically,(More)
There are characteristics of Hadamard matrices that enable an exhaustive search using algorithmic techniques. The search derives primarily from the eigenvalues which are constant after the Hadamard matrix is multiplied by its transpose. Generally this would be a performance concern but there are additional properties that enable the eigen-values to be(More)
