Collisions in preamble sampling WSNs cause a high waste of resources due to the mandatory transmission of a long preamble before every message. Moreover, when hidden terminals are present, collisions are even more noticeable since the vulnerability time is proportional to the long preamble duration. This effect reduces considerably the network performance… (More)

We describe the solution of linear systems of equations, Ax = b, on distributed-memory concurrent computers whose interconnect topology contains a two-dimensional mesh. A is assumed to be an <italic>M</italic>×<italic>M</italic> banded matrix. The problem is generalized to the case in which there are <italic>n<subscrpt>b</subscrpt></italic> distinct… (More)

Our project consists of two different parts: The first part contains an analysis of various pitch estimation algorithms. A number of different open-source pitch estimation libraries were tested using guitar recordings in order to gauge how accurately and consistently they outputted the correct frequencies. The results showed that the algorithms did not… (More)
