Une situation de violence intentionnelle infligée de l’extérieur, propulse le sujet sur une scène qui infiltre le présent d’une actualisation du passé et provoque un vertige abyssal qui invite à une figurabilité interne de traumas primordiaux conjugués à l’évènementiel. Cette expérience a valeur d’épreuve et force la mise au travail psychique.En s’appuyant sur la clinique des violences conjugales et de celle des victimes d’agression « sur la voie publique », trois axes de recherche sont proposés :- Les processus de répétition agis, cauchemardés ou oralisés, agents de changement.- Le corps et la psyché en tant que surfaces de réception et de figuration des violences- La prégnance du détail comme moteur essentiel du traitement du trauma.A la suite d’une agression, le processus astériforme fournit des points d’accroche pour faire bord au risque d’anéantissement grâce à un mouvement de reprise, par diffraction, focalisation, et unification-différenciation. Faute de pouvoir se représenter l’irreprésentable, à savoir le Réel de la mort, le sujet trace une esquisse, et met en place les prémices d’une figuration dont il va pouvoir se saisir. Après l’effondrement se dessine une possibilité de reconstruction<br>In situations where violence is deliberately inflicted from outside, the victim is propelled into a position where the present is infiltrated by an actualisation of the past and provokes a deep confusion linked to internal experiences of past events and primordial traumas. This experience has a test value and forces the beginning of the psychical work.Three axes of research are proposed in considering the victim experience in domestic as well as public violence:- To consider using acted, nightmares and verbalisation process of repetition as agents of change.- The body and the psyche as surfaces for reception and figuration of violence.- The use of expressed salient details as a driving force of the trauma treatment.Following an attack, the psychic asterism approach provides reference points and is able to promote the recovery process by way of diffraction, focusing an reunifying. In an attempt to represent the unrepresentable together with the reality of death, the victim will start to sketch the beginning of a figuration which he will be able to grab.Following a collapse, there begins to appear a possibility of rebuilding

ASTERISMS is a collection of lyric poetry that seeks to express a sense of awe for the natural world by exploring themes of science, art, and the self. By combining physics and metaphysics, scientific terminology and musings on love, ASTERISMS argues that these seemingly-disparate fields of knowledge can harmonize in unexpected ways. In its style, the collection draws from the works of Dorianne Laux, Pablo Neruda, and Annie Dillard. Most of the poems are written in free-version and are tied together by images of astronomy and wilderness, both modern and prehistoric. Poems about classical music appear as interludes meant to complement others concerned with science and technology, as music too has its own invented language. Like asterisms - ancient inventions meant to personalize the expansive mystery of the night sky - this collection seeks to admire, if not completely understand, our place in the natural world and cosmos beyond.

Firstly were addressed the concepts, requirements and elements associated with this technology and its interconnection with other communications technologies such as PSTN (Public Switched Telephone Network), ISDN (Integrated Services Digital Network) or GSM (Groupe Special Mobile). Furthermore, a study was carried out on the theoretical and practical Asterisk Open Source software, with the aim to explore its operation and features available, liable to be used in business environment. Finally, we developed in the company Clidis (Laboratory of Clinical Analyses in Sines) a solution based on this technology, where it was proved that the implementation of PBX / VoIP Gateways through Open Source software is a viable alternative to the real needs of business communication.

<p>In the thesis the advantages with Text over IP (ToIP) is explained and it is motivated why it is a good idea to integrate this in Asterisk. It also presents an implementation of a ToIP extension in Asterisk.</p><p>ToIP means communicating over a network based on Internet protocols with real-time text. Real-time text means a character is sent to the receiving terminal as soon the sender has typed it or with a small delay.</p><p>In the thesis IM and ToIP is compared in a survey. The result point at IM is not better than ToIP even though it is much more commonly used. VoIP can not replace ToIP either because there are occasions when ToIP is better for instance if the person using it is deaf or if a person want to make a private conversation in a noisy room.</p><p>Asterisk is an IP-PBX. PBX stands for Private Branch Exchange which means a private telephone system which is part of a larger network system that exchange information.</p><p>An IP-PBX is a PBX based on the Internet. Asterisk and many other IP-PBX can also exchange calls between the PSTN ant the Internet. By including ToIP in Asterisk it will be possible to exchange ToIP calls.</p><p>The implementation described is not only including ToIP in Asterisk but also a translation function between the text format called t140 and another text format called t140 with redundancy.</p><p>The idea is to extend the translation function in the future to more text formats.</p>

This thesis deals with the possibilities of video conferencing in Asterisk PBX and their use in practice. They also described the contingencies and how its configuration. Particular attention is paid to the protocols SIP, IAX and H.323, which are described in one of the chapters. The thesis was created by the Asterisk PBX, which demonstrates cooperation with videoconferencing clients. The thesis describes the configuration files so that the central set. Conclusion the work assesses the use of codecs for different clients.

This diploma dissertation is dealing with the VoIP software exchange Asterisk. In the dissertation there are described its abilities and possible ways of its configuration. Special attention is given to the signalling protocol SIP, which is described in one of the chapters. Within this dissertation a dial plan, which demonstrates the technique of dial plan creating, was created. Within the boundaries of the dialplan following services could be found: a voicemail, conference, Interactive Voice Response and call queues. Configuration files, with the help of which the exchange is configurated, are described in my dissertation as well. Finally, three laboratory assignments for purposes of the subject Multimedia Services are mentioned. Their main aim is to familiarise students with the creation of SIP accounts in the exchange, their mutual connections, defining the Interactive Voice Response and forming a new call centre.

Short Message Service (shortly SMS) is the most widely used type of communication systems. The main advantages are that allow a fast exchange of messages between devices, a very good availability through GSM and a reasonable price. Nowadays the SMS service support has expanded to include other technologies such as a service of the information navigation and the remote connection. The master‘s thesis concentrates on the Short Message Service, deals with basic principles and statements using by this service. The topic of the thesis is software PBX Asterisk and its possibility of SMS implementation, especially verification of SMS processing goes through the PSTN. After the basic introduction the master‘s work deals with the installation and configuration of the server. The main focus is on an installation of the operating system with an additional pack including necessary libraries and modules for a correct working of the server. The following section is paying attention to the Asterisk server configuration, especially a hardware card installation which is necessary for a connection with analog telephones, done by Bluetooth connections, set up user’s profiles of the SIP protocol and create a dial plan. This is followed by a verification of SMS option of the implementation and communication with GSM modem which is used as a gate for an exchange SMS between PSTN and GSM network. The last chapter of this master‘s thesis comes with the aimed results.

The thesis compares native SIP stack with PJSIP stack in the open source telephone private branch exchange (PBX) Asterisk. First, there are described both SIP protocol and Asterisk application. Subsequently, the architecture, new function support and the stacks setting possibilities are explored. For different exchange scenarios several commented configuration files are presented. The stacks are tested using Spirent TestCenter C1 software thereafter. In conclusion, selected properties are assessed and new PJSIP stack benefits are summarized. In addition, the laboratory assignment is attached.

This master’s thesis delves into the possibilities of the open-source Private Branch Exchange Asterisk, elaborates on its features and compares it with several other distros. The term SIP stack is explained here with the mention of two of its representatives. Further in the thesis, the security risks of the VoIP technology are explained, and specific attacks are described and then realized. As a part of the testing process, the possibilities of a custom module and its following implementation are explored, as well as the portability between the individual distros and its proper functioning.
