Deadlock prevention and avoidance in FMS : A Petri net based approach

Abstract: The use of structure theory of Petri nets to develop efficient deadlock prevention and deadlock avoidance methods for flexible manufacturing systems (FMSs) modelled by S4R nets is demonstrated Major synchronisation patterns, such as generalised parallel and sequential mutual exclusion, frequently observed in FMS contexts can be represented by this class The liveness property of a given S4R net (deadlock-freeness in the context of FMSs) is characterised in terms of structural Petri net elements called siphons An efficient method for controlling minimal siphons of a given S4R net is developed where local control places are added to the net A sufficient condition for liveness of the augmented net is provided This constitutes a deadlock prevention approach When the net liveness condition is not satisfied, an on-line controller, using a dynamic resource allocation policy, is developed for the augmented net The performance of the proposed approaches is illustrated using several examples

Breeding Structure of The House Mouse, Mus Musculus, in A Population Cage

Abstract: House mice ( Mus musculus ), released in a population cage consisting of a series of nest boxes connected by narrow runways, formed small breeding units or demes in each of four runs. Generally, each deme was composed of a “dominant” male, several females and several “subordinate” males. The formation of these breeding units appears to be primarily the result of male territoriality. However, females were also found to contribute to the maintenance of such units. Once formed, demes remained stable over a considerable period of time in spite of factors such as high animal density in some territories. In older demes “dominant” males were replaced by their offspring. Interdemic migration, once demes were established, was rare and appeared to be possible only through females. Attempts to introduce mice into established demes of five to eight animals failed unless at least four mice were introduced simultaneously. The existence of stable demes may explain a number of enigmatic situations encountered in natural populations of Mus musculus .

Coping, acculturation, and psychological adaptation among migrants: a theoretical and empirical review and synthesis of the literature

Abstract: Given the continuous, dynamic demographic changes internationally due to intensive worldwide migration and globalization, the need to more fully understand how migrants adapt and cope with acculturation experiences in their new host cultural environment is imperative and timely. However, a comprehensive review of what we currently know about the relationship between coping behavior and acculturation experience for individuals undergoing cultural changes has not yet been undertaken. Hence, the current article aims to compile, review, and examine cumulative cross-cultural psychological research that sheds light on the relationships among coping, acculturation, and psychological and mental health outcomes for migrants. To this end, this present article reviews prevailing literature pertaining to: (a) the stress and coping conceptual perspective of acculturation; (b) four theoretical models of coping, acculturation and cultural adaptation; (c) differential coping pattern among diverse acculturating migrant groups; and (d) the relationship between coping variabilities and acculturation levels among migrants. In terms of theoretical understanding, this review points to the relative strengths and limitations associated with each of the four theoretical models on coping-acculturation-adaptation. These theories and the empirical studies reviewed in this article further highlight the central role of coping behaviors/strategies in the acculturation process and outcome for migrants and ethnic populations, both conceptually and functionally. Moreover, the review shows that across studies culturally preferred coping patterns exist among acculturating migrants and migrant groups and vary with migrants' acculturation levels. Implications and limitations of the existing literature for coping, acculturation, and psychological adaptation research are discussed and recommendations for future research are put forth.
