These days randomized-based population optimization algorithms are in wide use in different branches of science such as bioinformatics, chemical physics andpower engineering. An important group of these algorithms is inspired by physical processes or entities’ behavior. A new approach of applying optimization-based social relationships among the members of a community is investigated in this pa...

Consider an exchangeable normal vector with parameters ????2, and ?. On the basis of a vector observation some tests about these parameters are found and their properties are discussed. A simulation study for these tests and a few nonparametric tests are presented. Some advantages and disadvantages of these tests are discussed and a few applications are given.

esults: At 40-Hz stimulation, SZ and AFF had significantly reduced phase locking compared with HC. This deficit was more pronounced ver the left hemisphere in SZ. Evoked power at 40 Hz was also reduced in the patients compared with HC. At 30-Hz stimulation phase ocking and evoked power were reduced in both patient groups. The 20-Hz ASSR did not differ between groups, but phase locking and voked...

Sudden death, during or just after labour, has only too often been attributed to " obstetric shock." Out of this aetiological obscurity, in 1941 and 1942, Steiner and Lushbaugh extracted one recognizable cause of death, the finding in the maternal blood vessels of amniotic material. Recognition of other cases has followed rapidly (see review by Sluder and Lock, 1952), but thus far only three re...

Recently, a number of usage data representations have emerged that enable the representation of user activities across system and application boundaries. Based on these user activity data, systems can adapt to the users and provide personalized information. A lot of usage data representation formats are already successfully used in real world applications. However, dependent on the purpose, the...
