This cutting-edge book shows you how SIP provides a highly-scalable and cost-effective way to offer new and exciting telecommunication feature sets, helping you design your \"next generation\" network and develop new applications and software stacks. Other key discussions include SIP as a key component in the Internet multimedia conferencing architecture, request and response messages, devices in a typical network, types of servers, SIP headers, comparisons with existing signaling protocols including H.323, related protocols SDP (Session Description Protocol) and RTP (Real-time Transport Protocol), and the future direction of SIP. Detailed call flow diagrams illustrate how this technology works with other protocols such as H.323 and ISUP. Moreover, this book covers SIP RFC 3261 and the complete set of SIP extension RFCs.

Now in its third edition, the ground-breaking Artech House bestseller SIP: Understanding the Session Initiation Protocol offers you the most comprehensive and current understanding of this revolutionary protocol for call signaling and IP Telephony. The third edition has been significantly expanded with brand new chapters on NAT traversal, SIP security, services in SIP, presence and instant messaging, Peer-to-Peer SIP, and an introduction to ABNF and XML.

Comment augmenter prodigieusement l''impact de vos présentations? Une présentation n''offre qu''une unique chance de séduire sa cible. Elle correspond bien souvent au « moment de vérité », déterminant la signature ou non d''un contrat crucial, la conclusion d''une vente, l''obtention d''un capital, l''adhésion d''une équipe..… Échouer revient à laisser passer une affaire, voire saboter l''opportunité d''une vie entière. À l''inverse, une présentation professionnelle bien menée peut démultiplier vos chances de « vendre » votre image, produit ou service.Ce livre vous montrera comment: • Connaître votre public et parler son langage pour créer l'empathie; •Utiliser les techniques narratives pour élaborer une présentation captivante; • Structurer un message concis et cohérent; • Créer des slides qui renforcent vos messages; • P•résenter face au public avec assurance et obtenir son adhésion.Une entité municipale ne peut faire l''impasse sur une réflexion quant aux attitudes et aux moyens à adopter pour mieux communiquer avec les citoyens que nous sommes. Ce livre propose une méthode qui n''a rien de « hard »! L''auteur se base sur des principes simples, et fournit un soutien pas à pas, illustré d''anecdotes vécues et des exemples qui vous aideront à transformer des concepts complexes en idées claires, qui touchent le public et qui restent gravés dans sa mémoire. Pour une maîtrise de votre prestation, afin de séduire votre auditoire et de lui laisser une impression excellente... et durable! À PROPOS DE L'AUTEURAprès avoir décroché un Master en Communication visuelle et en Fashion Design dans son pays natal qu'est le Brésil, Giselle Hardt a continué son apprentissage théorique en Belgique, étoffé au fil des ans par l'observation pratique. Aujourd'hui, Giselle Hardt anime de nombreuses conférences ainsi que des ateliers afin d'aider chacun à appliquer la méthode Hardt.EXTRAIT Chapitre 1 Qu'est-ce qu'une bonne présentation? De même qu'il est plus facile d'imaginer l'enfer que le paradis, il est plus aisé de se figurer une mauvaise qu'une bonne présentation.Qui ne s'est jamais senti somnolent ou ennuyé en assistant à un exposé interminable, regorgeant de listes à puces et de textes fades rehaussés d'animations plus loufoques que subtiles? Sans parler du présentateur monocorde ou confus, tellement absorbé par ses graphiques qu'il se révèle incapable du moindre sourire, voire d'un simple regard vers son auditoire.Une telle séance d'hypnose provoque le sentiment amer d'avoir gaspillé un temps précieux à écouter sans rien apprendre. L'information, même pertinente, ne vaut rien sans une mise en scène captivante. Pourtant, les mauvaises présentations sont légion.Rien d'étonnant à cela lorsqu'on sait le peu de soin qu'apportent de trop nombreux professionnels à la préparation de leur intervention. Tant de présentations sont bâclées en une poignée d'heures, parfois la veille ou le matin même.

The demand for automatic detection of Novel Coronavirus or COVID-19 is increasing across the globe. The exponential rise in cases burdens healthcare facilities, and a vast amount of multimedia healthcare data is being explored to find a solution. This study presents a practical solution to detect COVID-19 from chest X-rays while distinguishing those from normal and impacted by Viral Pneumonia via Deep Convolution Neural Networks (CNN). In this study, three pre-trained CNN models (EfficientNetB0, VGG16, and InceptionV3) are evaluated through transfer learning. The rationale for selecting these specific models is their balance of accuracy and efficiency with fewer parameters suitable for mobile applications. The dataset used for the study is publicly available and compiled from different sources. This study uses deep learning techniques and performance metrics (accuracy, recall, specificity, precision, and F1 scores). The results show that the proposed approach produced a high-quality model, with an overall accuracy of 92.93%, COVID-19, a sensitivity of 94.79%. The work indicates a definite possibility to implement computer vision design to enable effective detection and screening measures.

This paper surveys the current state-of-the-art of technology, systems and applications in Augmented Reality. It describes work performed by many different research groups, the purpose behind each new Augmented Reality system, and the difficulties and problems encountered when building some Augmented Reality applications. It surveys mobile augmented reality systems challenges and requirements for successful mobile systems. This paper summarizes the current applications of Augmented Reality and speculates on future applications and where current research will lead Augmented Reality’s development. Challenges augmented reality is facing in each of these applications to go from the laboratories to the industry, as well as the future challenges we can forecast are also discussed in this paper. Section  1 gives an introduction to what Augmented Reality is and the motivations for developing this technology. Section  2 discusses Augmented Reality Technologies with computer vision methods, AR devices, interfaces and systems, and visualization tools. The mobile and wireless systems for Augmented Reality are discussed in Section  3 . Four classes of current applications that have been explored are described in Section  4 . These applications were chosen as they are the most famous type of applications encountered when researching AR apps. The future of augmented reality and the challenges they will be facing are discussed in Section  5 .

The use of mobile applications (apps) has been growing in the world of technology, a phenomenon related to the increasing number of smartphone users. Even though the mobile apps market is huge, few studies have been made on what makes individuals continue to use a mobile app or stop using it. This study aims to uncover the factors that underlie the continuance intention to use mobile apps, addressing two theoretical models: Expectation confirmation model (ECM) and the extended unified theory of acceptance and use of technology (UTAUT2). A total of 304 questionnaires were collected by survey to test the theoretical framework proposal, using structural equation modelling (SEM). Our findings indicate that the most important drivers of continuance intention of mobile apps are satisfaction, habit, performance expectancy, and effort expectancy.
