This paper reports the development of a Matlab toolbox for computational analysis of piecewise linear systems. The analysis is based on piecewise quadratic Lyapunov functions, which are computed via convex optimization. In this way, exponential stability and system performance can be assessed. The toolbox also supports efficient simulation of systems with discontinuous dynamics and sliding modes.
During outdoor storage of large quantities of wood fuels, hydrocarbons are emitted into air in gas phase and leached out into the ground by precipitation. To investigate to what extent these emissions have environmental or health effects, sampling has been done on wood chip piles in an existing terminal storage situated in the south of Sweden, north east of Växjö. Sampling was done by solid phase

Yersiniosis and shigellosis are two bacteria-borne and food-related diseases that lead to significant costs in terms of direct costs (costs of healthcare, medicine, rehabilitation etc.), indirect costs (lost productivity due to absenteeism) and intangible costs (pain, nausea and other intangible aspects that can be linked to disease). It is essential to estimate these costs, partly to be able to c

A procedure for automatic monitoring of control-loop performance is presented. The control loop performance monitor (CLPM) detects oscillations in the control loop. These oscillations are normally caused by too-high friction in the control valve, but there are other reasons as well. The CLPM is primarily intended to be connected to PID controllers, but it can also be connected to other controllers
