In split-dose experiments, the time relationship for the interaction of primary breaks in the formation of dicentric chromosomes was analysed. Human peripheral lymphocytes were irradiated with a dose of 340 R of 220 kV X-rays split into two equal fractions separated by intervals up to 360 min. Assuming an exponential decline of the time-dependent quadratic(More)
Testing Integrated Circuits is a costly process. The present article investigates combinatorial optimization problems reducing subsets of tests, which are redundant in a statistical sense. The solution to those problems is brought about by application of the Simulated Annealing local search technique, which, in turn makes wide use of random number(More)
Model Renewal processes have been a frequent object of analysis in early studies of stochastic processes, see Cox (1962), for instance. Only recently the idea of parallel renewal processes receives more attention, see Borgelt and Picado-Muino (2012), Gaigalas (2003), Kai et al. (2014), CRC (1994), Kallen et al. (2010), Truccolo (2005), Modir et al. (2010).(More)
One of the most important concepts in an automotive production process is that of a manufacturing sequence. Sequencing has a vital influence on a series of important performance indicators such as load balance, setup time, setup cost, timeliness, flow of material etc. Generating appropriate sequences has thus become a key task for the automotive production(More)
Abstract: Technical processes, notably in the power transforming industries, generate a wealth of process data, commonly organized in a file with M records and 1 + n + m fields, i.e. a time stamp, followed by n independent and m dependent variables, summarized in the vectors x and y, respectively. Regardless of the availability of physical models it is(More)
