Interaction signatures and action templates in the ODP computational viewpoint

International audienceIn this work we raise two issues that we came across when aiming to formalize both interaction signatures and action templates within the ODP computational viewpoint. We discuss these two concepts and present a way to formalize them by introducing a new term to formal descriptions of interaction signatures. In the same spirit as other works, our aim is to address issues concerning how concepts of the ODP computational viewpoint are currently defined as we present some solutions to their formalisation. If required, our work aim to serve as a step to help improve or change the current process of formalizing the ODP computational viewpoint concepts using the UML language

Towards a refinement of the open distributed systems interactions signatures

International audienceThe ODP framework defines a set of concepts and an architecture for the construction of ODP systems in terms of five viewpoints. The computational viewpoint supports three models of interaction, each of which has an associated kind of computational interface: signals and signal interfaces, flows and stream interfaces, operations and operation interfaces. In this paper we address both the functional decomposition and constraints specification on interactions signatures. We show how to refine an operation signature into a signal signature. And finally, we use OCL to express constraints on interaction signatures refinements. The result is an UML model which can serve as a basis to define end-to-end QoS in open distributed systems, and the operation of multi-party binding and bindings between different kinds of interfaces (e.g. stream to operation interface bindings). That is, QoS require-ments on interactions in the computational viewpoint might be specified just using signals. We are investigating this issue

Victim, perpetrator, and offense characteristics in filicide and filicide-suicide

The purpose of this paper is to provide a critical review of most recent studies of parental and stepparental filicide. A detailed review of the literature revealed the importance of certain demographic, environmental, and psychosocial factors in the commission of child homicide. Our findings indicate that filicides perpetrated by genetic parents and stepparents differ considerably in terms of underlying motivational factors. Data in the literature suggest that biological parents are more likely to choose methods of killing which produce quick and painless death, whereas stepparents frequently kill their wards by beating. Research results demonstrate the victims of maternal filicides to be significantly younger than the victims of paternal filicides. Additionally, filicide–suicide is most often associated with parental psychopathology. Genetic fathers are at the greatest risk of death by suicide after the commission of familicide. These findings are discussed in relation to theoretical frameworks explaining the occurrence of child murder. Further, limitations of reviewed studies and directions for future research are presented

Metamorphosis in the Cirripede Crustacean Balanus amphitrite

Stalked and acorn barnacles (Cirripedia Thoracica) have a complex life cycle that includes a free-swimming nauplius larva, a cypris larva and a permanently attached sessile juvenile and adult barnacle. The barnacle cyprid is among the most highly specialized of marine invertebrate larvae and its settlement biology has been intensively studied. By contrast, surprisingly few papers have dealt with the critical series of metamorphic events from cementation of the cyprid to the substratum until the appearance of a suspension feeding juvenile. This metamorphosis is both ontogenetically complex and critical to the survival of the barnacle. Here we use video microscopy to present a timeline and description of morphological events from settled cyprid to juvenile barnacle in the model species Balanus amphitrite, representing an important step towards both a broader understanding of the settlement ecology of this species and a platform for studying the factors that control its metamorphosis. Metamorphosis in B. amphitrite involves a complex sequence of events: cementation, epidermis separation from the cypris cuticle, degeneration of cypris musculature, rotation of the thorax inside the mantle cavity, building of the juvenile musculature, contraction of antennular muscles, raising of the body, shedding of the cypris cuticle, shell plate and basis formation and, possibly, a further moult to become a suspension feeding barnacle. We compare these events with developmental information from other barnacle species and discuss them in the framework of barnacle settlement ecology

Integrating Asterisk with InRule to Detect Suspicious Calls

International audienceMonitoring telecommunications systems is of a crucial importance. Nowadays, PBX software packages can be configured to allow the storage of Call Detail Records in a database. There is a permanent need to analyze those records and allow business owners to detect PBX misuse from inside and outside the company. The word "misuse" covers an employee making too many personal phone calls, a salesman making fewer phone calls than expected, a client making an excessive number of phone calls, and other suspicious calls. A data-mining package or any other analytical tool would not be as efficient because it would report what happened when it is too late to take action. In this article, we integrate Asterisk with a rule-based engine called InRule. Asterisk will consult InRule whenever a call is about to be made and thus take appropriate actions

Implementing intelligent network services in VoIP application with SIP, TRIP and ENUM

International audienceInternet telephony must offer the standard telephony services. However, the transition to Internet-based telephony services also provides an opportunity to create new services more rapidly and with lower complexity than in the existing public switched telephone network (PSTN). The Session Initiation Protocol (SIP) is a signaling protocol that creates, modifies and terminates associations between Internet end systems. SIP implements services such as call forwarding and transfer, placing calls on hold, camp-on and call queuing by a small set of call handling primitives. The Session Initiation Protocol (SIP) uses DNS procedures to allow a client to resolve a SIP URI INTO data_ds.tmp_pub_the IP address, port, and transport protocol of the next hop to contact. Generally, these are the problems of mapping the name of a destination INTO data_ds.tmp_pub_an address, and to find the best route to the destination in a combined IP and PSTN network. Two protocols are being developed by the Internet Engineering Task Force (IETF) to solve these problems. The Telephony Routing over IP (TRIP) protocol solve the gateway location problem by distributing routing information between entities on the IP network. The tElephony NUmbering Mapping (ENUM) provides a solution to the terminal location problem based on DNS. This paper describes the problem of Implementing Intelligent Network Services in VoIP application with SIP (Signalling protocol), TRIP (Routing protocol over IP) and ENUM

Contrôle des sessions SOAP par SIP ( WS-routing)

International audienceL'architecture orientée vers les services offre un modèle de programmation qui permet à des composants logiciels développés séparément d'être publiés, identifiés et invoqués les uns par les autres. Ces composants peuvent résider sur un même réseau ou sur des réseaux distincts. L'architecture des services Web utilise XML pour construire divers protocoles d'échange de messages. SOAP, WSDL et UDDI sont parmi les plus populaires qui offrent une couche supplémentaire entre applications et d'autres protocoles. Le routage des messages SOAP entre différents noeuds repose essentiellement sur le protocole unidirectionnel WS-routing (Web Service Routing) pour aboutir à sa destination a travers des intermédiaires. Mais SOAP ne peut pas garder l'état de la session entre des appels SOAP. Pour des applications interactives, transactions des informations entre des services Web ou E-commerce, il faut avoir un maintien d'état des sessions. De même SOAP ne décrit pas l'ordre d'exécution des différentes applications, et la requête SOAP ne spécifie pas comment passer de la combinaison de l'URI de l'objet destination au code exécutable. Ainsi, il faut tout d'abord découvrir les URI des services disponibles pour formuler correctement les requêtes SOAP. Dans ce papier nous explicitons les caractéristiques de protocole de contrôle et gestion de sessions SIP (Session Initiation Protocol) pour proposer une technique permettant de contrôler les sessions SOAP dans la transaction des informations entre services Web et résoudre le problème de la découverte des URIs
