Suppose that we are given as input an object O and we’d like to know if it has some property P . But querying the object is expensive, so we would like to do a small number of local queries on the object. Usually, deciding with certainty whether an object has a property or not will require a lot of queries. The idea of property testing is to answer an easier question, thus allowing less queries...

Protecting IP in the new global environment requires new information, new thinking and new strategies. While experienced legal counsel should always be sought when making global IP decisions, engineering, marketing, and sales people with limited experience in global IP protection often become involved in such decisions and therefore need to be familiar with key global IP issues. Here, we presen...

We develop a primal dual active set with continuation algorithm for solving the l-regularized least-squares problem that frequently arises in compressed sensing. The algorithm couples the the primal dual active set method with a continuation strategy on the regularization parameter. At each inner iteration, it first identifies the active set from both primal and dual variables, and then updates...
