This document is an introduction to the Matlab package SDLS (Semi-Definite Least-Squares) for solving least-squares problems over convex symmetric cones. The package is shortly presented through the addressed problem, a sketch of the implemented algorithm, the syntax and calling sequences, a simple numerical example and some more advanced features. The implemented method consists in solving the...

We present COBS — a model of a concurrent object-based computational system with handshakes as elementary actions of inter-process communication. Processes are considered to be partial views of the system. Their communication by asynchronous message passing and variable sharing is modeled by elementary processes on the same abstraction level. The same acts of computation and communication can b...

With the arrival of GPS, satellite remote sensing, and personal computers, the last two decades have witnessed rapid advances in the field of spatially-explicit marine ecological modeling. But with this innovation has come complexity. To keep up, ecologists must master multiple specialized software packages, such as ArcGIS for display and manipulation of geospatial data, R for statistical analy...
