The results of experimental studies of energy fluxes released during the diode target blow-up initiated by a high-current relativistic electron beam are presented in the paper. The energy of target explosion products required for realization of the observed diode structural elements deformation is being estimated. Measurements of the target explosion products parameters and finite-element modeling of the mechanical deformation of the cathode system elements show an energy release during the target explosion that far exceeds the energy input.
The possibilities and effectiveness of affective contact of a person with the world are connected with his/her psychological borders. Such as: the subjective symbol of the transition; the scope of ...potential normative and dysfunctional meanings and possibilities; and the field of non-adaptive activity. The regulatory and adaptive role of the affective system in unstable situations is realized in affective expansion, which determines a person’s contact with the boundaries of one's own Defined Self as "Challenge ↔ Challenge " and his/her desire to risk in their reconstruction. The set of functions of affective expansion makes it a universal regulator of the whole spectrum of personal adaptations with respect to stereotypes and innovations. The formation of the "border experience" and of the dispositions of an individual, reflecting the relationship between its needs and the conditions of their satisfaction at the interface Self and not-Self, is analyzed in the context of normal and disharmonious personogenesis. The following mechanisms of interaction of affective expansion of a person with his/her borders are described: attraction, protection, inhibition, mechanisms of "swing" and turning "-" into "+". Dispositional and situational dominants of these mechanisms in their system interaction are designated as a future investigation of their connection with the nature of affective expansion.
Возможности и эффективность аффективного контакта человека с миром связаны с его психологическими границами: субъективным символом перехода, областью потенциальных нормативных и дисфункциональных смыслов и возможностей и полем неадаптивной активности. Регуляторно-адаптационная роль аффективной системы в нестабильных ситуациях реализуется в аффективной экспансии, определяющей контакт человека с границами своего Я как «вызов ↔ вызов» и его стремление к риску в их реконструкции. Совокупность функций аффективной экспансии делает ее универсальным регулятором всего диапазона личностных адаптаций в отношении стереотипов и новаций. Формирование «опыта границы» и диспозиций личности, отражающих взаимоотношение ее потребностей и условий их удовлетворения на границе контакта Я и не-Я, анализируется в контексте нормального и дисгармоничного персоногенеза. Описаны механизмы взаимодействия аффективной экспансии человека с его границами: аттракция, протекция, ингибиция, механизмы «качелей» и превращения «-» в «+». Диспозиционная и ситуативная доминанты этих механизмов в их системном взаимодействии обозначены как перспектива исследования их связи с характером аффективной экспансии.
HEP experiments produce enormous data sets at an ever-growing rate. To cope with the challenge posed by these data sets, experiments' software needs to embrace all capabilities modern CPUs offer. ...With decreasing memory core ratio, the one-process-per-core approach of recent years becomes less feasible. Instead, multi-threading with fine-grained parallelism needs to be exploited to benefit from memory sharing among threads. Gaudi is an experiment-independent data processing framework, used for instance by the ATLAS and LHCbexperiments at CERN's Large Hadron Collider. It has originally been designed with only sequential processing in mind. In a recent effort, the frame work has been extended to allow for multi-threaded processing. This includes components for concurrent scheduling of several algorithms - either processingthe same or multiple events, thread-safe data store access and resource management. In the sequential case, the relationships between algorithms are encoded implicitly in their pre-determined execution order. For parallel processing, these relationships need to be expressed explicitly, in order for the scheduler to be able to exploit maximum parallelism while respecting dependencies between algorithms. Therefore, means to express and automatically track these dependencies need to be provided by the framework. In this paper, we present components introduced to express and track dependencies of algorithms to deduce a precedence-constrained directed acyclic graph, which serves as basis for our algorithmically sophisticated scheduling approach for tasks with dynamic priorities. We introduce an incremental migration path for existing experiments towards parallel processing and highlight the benefits of explicit dependencies even in the sequential case, such as sanity checks and sequence optimization by graph analysis.
The data processing model of the LHCb experiment implies handling of an evolving set of heterogeneous metadata entities and relationships between them. The entities range from software and databases ...states to architecture specificators and software/data deployment locations. For instance, there is an important relationship between the LHCb Conditions Database (CondDB), which provides versioned, time dependent geometry and conditions data, and the LHCb software, which is the data processing applications (used for simulation, high level triggering, reconstruction and analysis of physics data). The evolution of CondDB and of the LHCb applications is a weakly-homomorphic process. It means that relationships between a CondDB state and LHCb application state may not be preserved across different database and application generations. These issues may lead to various kinds of problems in the LHCb production, varying from unexpected application crashes to incorrect data processing results. In this paper we present Ariadne – a generic metadata relationships tracking system based on the novel NoSQL Neo4j graph database. Its aim is to track and analyze many thousands of evolving relationships for cases such as the one described above, and several others, which would otherwise remain unmanaged and potentially harmful. The highlights of the paper include the system's implementation and management details, infrastructure needed for running it, security issues, first experience of usage in the LHCb production and potential of the system to be applied to a wider set of LHCb tasks.
