Academic literature on the topic 'Info-Communication devices'

The paper reviews the use of multidimensional measuring and control variables and their modern hardware and software in conversion of power sources to secondary signals in the power supply processes of computing and infocommunication devices, the principles of monitoring them, receiving signals to ensure smooth and quality operation of devices. It also elucidates the principle of construction, model and software of working and transmitting media on an appropriate basis. The developed power supply control device is based on the ongoing processes and functional modules selected when the device was assembled. According to the main objective of the study, a monitoring algorithm and software package were developed based on the built-in system architecture. The implemented model was used to describe integration processes taking place between the hardware and software for monitoring, in detail. The research enabled developing and introducing models of IDEF database destined for collection and processing of statistical data in monitoring processes of a software package. Practical results from generation of sources of electricity and its use in enterprises by month, year and day, are presented in the form of graphs and tables.

The widespread application of wireless communication technology brings great convenience to people, but security and privacy problems also arise. To assess and guarantee the security of wireless networks and user devices, discovering and identifying wireless devices become a foremost task. Currently, effective device identification is still a challenging issue, as device fingerprinting requires huge training datasets and is difficult to expand, and rule-based identification is not accurate and reliable enough. In this paper, we propose WND-Identifier, a universal and extensible framework for the identification of wireless devices, which can generate high-precision device labels (vendor, type, and product model) efficiently without user interaction. We first introduce the concept of device-info-related network protocols. WND-Identifier makes full use of the natural language features in such protocol messages and combines with the device description in the welcome page, thereby utilizing extraction rules to generate concrete device labels. Considering that the device information in the protocol messages may be incomplete or forged, we further take advantage of the application logic independence and stability of the device-info-related protocol, so as to build a multiprotocol text classification model, which maps the device to a known label. We conduct experiments in homes and public networks and present three application scenarios to verify the effectiveness of WND-Identifier.

Internet of Things(IOT) is the rising innovation without bounds is required to associate billions of devices. IoT is the future where many low power resources and constrained devices are connected by means of the internet for communication, compute process and take actions in the communication network. The increased number of communication is relied upon to produce heaps of information and the security of information can be a threat resulting a secure solution for communication is necessitates among heterogenous devices. Focus of the work is to provide confidentiality, authentication and integrity of data in transit between IoT edge devices and back-end systems. This paper proposes a lightweight hybrid encryption system using ECDH key exchange mechanism for generating keys and establishing connection, digital signature for authentication, thereafter AES algorithm for encryption and decryption of user data file. The proposed combination is referred to as “three way secured data encryption mechanism” which interpret all the 3 protection schemes of authentication, info security and verification with the characteristics of lower calculation cost and faster speed makes it robust for hackers to crack the security system, thereby protective data in transmission.

Certain technological improvements mean the obvious rethinking of the boundaries of the private sphere. This process has made a legislative response necessary. In this sense, Act LIII of 2018 can be highlighted, which states in its preamble that the modern devices of info communication have laid new foundation for the everyday communication, hence the protection of private life extends beyond the physical harassment to Internet. An important factor in the protection of privacy is the responsibility of companies, which must ensure the protection of the privacy rights of entities using their online interfaces.

In this work, a cheaper alternative method of determining path loss using Network cell info lite software is proposed. Hata-Okumura model is used in the determination of path loss and signal strength of mobile communication devices within Ibogun and Ifo, a suburban community in Ogun state, Nigeria. Additionally, this paper is also aimed at determining the path loss under transmission line to ensure proper network planning in areas covered by transmission lines. Result obtained shows that areas with pylons have greater path loss compared to areas with no pylons. It is recommended that the power levels of base station operating in this area should be increased.

The emergence of the new digital platforms, a diversified number of approaches and providers cannot damage too much a rather crowded info sphere. What may come as a general challenge is the “performance” amateurs who have the devices, the will but not the skills to become reliable communicators. Good training and an expanded concern for the accuracy of messages should distinguish between fact and fiction and between information and opinion. The smart phone, the iPod, the lap top or the tablet have expanded the means of communication. They have also diversified the types of messages circulated. The traditional main stream media outlets are facing a mounting competition from the social networks populated with the folk journalists, albeit, non-professionals. Basic training of all those willing to come into the communication ring and regulations that may concern not only the professionals but also the amateurs, may be ways to get over what seems to be a deadlock.

IoT devices (sensors, drones, cameras) are gaining more and more emphasis on military operations. The application of IoT elements in the military environment increases situational awareness and supports the acquisition and maintenance of information superiority. The information they provide about the enemy, the area of operations, and the location and status of our soldiers and assets can contribute to the successful execution of operations at the tactical, operational and strategic levels. However, they can also pose serious threats if their vulnerabilities allow the data they collected to leak or they provide access to the info-communication networks used for the enemy. In this article, the author examined the vulnerabilities of these IoT devices using keyword analysis. After drawing conclusions from the analysis of the relevant literature, he compared the results with the general-purpose IoT threats and attacks typical of today, like distributed denial of service attacks, security, software, security and privacy issues.

Advances in the info and communication knowledge have led to the emergence of Internet of things (IoT). Internet of things (loT) is worthwhile to members, trade, and society seeing that it generates a broad range of services by interconnecting numerous devices and information objects. Throughout the interactions among the many ubiquitous things, security problems emerge as noteworthy, and it is significant to set up more suitable solution for security protection. Nonetheless, as loT devices have limited resource constraints to appoint strong protection mechanisms, they are vulnerable to sophisticated security attacks. For this reason, a sensible authentication mechanism that considers each useful resource constraints and safety is required. Our proposed scheme uses the standards of Elliptic Curve digital signature scheme and evaluates systematically the efficiency of our scheme and observes that our scheme with a smaller key size and lesser infrastructure performs on par with the prevailing schemes without compromising the security level.

Depuis la fin des années 1990, face aux risques sanitaires multiples associés à l’alimentation, les écoles sont devenues un champ d’intervention privilégié pour sensibiliser les enfants à la « bonne » alimentation. En France, diverses instances publiques se sont associées pour concevoir et diffuser de vastes campagnes info-communicationnelles à l’échelle nationale dont l’un des objectifs consiste à éduquer les enfants à un ensemble de normes et valeurs liées à ce qui est aujourd’hui désigné comme sain. Cette thèse se propose de saisir les enjeux de cette communication publique ainsi que sa circulation d’instance en instance et d’acteur en acteur jusque dans les écoles. Elle s’appuie sur une analyse sémio-pragmatique des dispositifs info-communicationnels et infopédagogiques produits de 2010 à 2015 par les instances publiques, ainsi que sur des observations participantes et des entretiens semi-directifs dans les écoles. Cette enquête fait apparaître deux logiques à l’œuvre. D’une part, traduits en prescriptions, protocoles et missions selon les différentes échelles territoriales et institutionnelles, les messages de santé publique montrent la volonté d’inculquer aux enfants des modèles normatifs afin qu’ils apprennent à diriger par eux-mêmes leurs conduites et celles des autres. D’autre part, ces prescriptions et dispositifs sont adaptés, transformés, réappropriés et détournés de leur objectif premier à chaque étape de leur circulation. À l’origine de ces transformations, les acteurs successifs forment une chaîne dont les derniers maillons sont les enfants
Since the end of 1990s and facing up to numerous sanitary risks associated to food, schools became the favorite field of intervention to make children sensitive to so-called “proper”food. In France, diverse public authorities joined to develop and diffuse vast information and communication campaigns on a national scale. One purpose of these campaigns is educatingchildren in a set of standards, norms and values bound to what is seen today as healthy. This work is dedicated to understand what is at stake in this public communication as well as its progress through various authorities and various actors up to schools. It is built upon a semio pragmatic analysis of informative and pedagogical scheme produced between 2010 and 2015 by public authorities as well as observations and semi-directive interviews in schools. This work reveals two logics. On one hand, as messages about public health are translated into prescriptions, protocols and missions according to the various territorial and institutional scales, they demonstrate the will to instill normative models into children so that they learn to manage by themselves their conducts and those others. On the other hand, those prescriptions and devices are adapted, transformed and diverted from their first objective in every stage of their progress. At the origin of these transformations, the successive actors form a chain the last links of which are the children

La thèse s’intéresse à la manière dont les pouvoirs publics communiquent en matière de prévention des maladies chroniques que sont le cancer, le diabète et l’hypertension artérielle. Face aux résultats mitigés des campagnes de prévention sur les maladies chroniques en Côte d’Ivoire, notre recherche examine les enjeux auxquels doivent répondre l’information et la communication. Il apparaît que la communication de prévention est traversée par des enjeux économiques, politiques et socioculturels. Nous interrogeons le concept de « gouvernementalité » développé par Michel Foucault en général et plus spécifiquement les notions de biopolitique, de l’instrumentation de l’action publique et de résistances dans les rapports de pouvoir dans le cadre de la prévention des maladies chroniques. Notre analyse porte sur un corpus hétérogène constitué de douze (12) entretiens semi-directifs avec des acteurs institutionnels et communautaires de la prévention, d’une enquête auprès de trois cent soixante-neuf (369) patients de l’unité d’oncologie du Centre Hospitalier Universitaire de Treichville et d’une analyse de contenu de trois (3) fils de discussion issus d’un groupe de discussion en ligne sur Facebook dédié à la médecine traditionnelle. Après l’analyse, il en ressort trois observations majeures. La communication de prévention est sujette à une prééminence des logiques politiques. De fait, elle constitue un instrument de biopouvoir qui contribue dans une certaine mesure au déploiement de la stratégie politique des gouvernants et participe de ce fait, au renforcement de leur légitimité. Cependant, les dispositifs info-communicationnels de la prévention comportent des insuffisances. Il s’agit entre autres de leur décalage avec les réalités locales notamment en ce qui concerne certains facteurs socioculturels, à l’instar de l’analphabétisme, de la relation positive de la société ivoirienne avec l’embonpoint et du recours à la médecine traditionnelle chez une partie de la population. En raison de ces insuffisances, les populations développent des formes de résistances face aux discours institutionnels de prévention à travers des attitudes de déni, de rejet et des réflexions dubitatives
This thesis examines the way in which public authorities communicate about the prevention of chronic diseases such as cancer, diabetes and hypertension. Faced with the mixed results of prevention campaigns on chronic diseases in Côte d'Ivoire, our research examines the issues that information and communication must address. It appears that economic, political and socio-cultural issues affect prevention communication. We question the concept of "governmentality" developed by Michel Foucault in general and more specifically the notions of biopolitics, the instrumentation of public action and resistances in power relations in the context of chronic disease prevention. Our analysis is based on a heterogeneous corpus consisting of twelve (12) semi-directive interviews with institutional and community actors in prevention, a survey of three hundred and sixty-nine (369) patients in the oncology unit of the Centre Hospitalier Universitaire de Treichville and a content analysis of three (3) threads from an online discussion group on Facebook dedicated to traditional medicine. After the analysis, three major observations emerged. Preventive communication is subject to a pre-eminence of political logics. In fact, it constitutes an instrument of biopower that contributes to a certain extent to the deployment of the political strategy of those in power and thus helps to strengthen their legitimacy. However, the info-communication mechanisms of prevention have their shortcomings. These include their lack of connection with local realities, particularly with regard to certain socio-cultural factors, such as illiteracy, the positive relationship of Ivorian society with overweight and the use of traditional medicine by part of the population. Because of these shortcomings, the population develops forms of resistance to institutional prevention discourse through attitudes of denial, rejection and doubtful thinking

Cette recherche menée au sein de l’organisation GRDF rassemble à la fois l’instrumentation numérique à vocation sociotechnique et l’Intelligence Collective afin d’interroger la capacité de construction de l’organisation par ses membres à travers une notion présentée : l’ « eXpérience Organisation ». Ces transformations de l’entreprise répondent à des tendances dans le secteur énergétique (transition écologique) et à des attentes des salariés de l’entreprise.Après avoir présenté l’hybridité de l’organisation étudiée et son inscription dans la « Société de l’Information », l’accent est mis sur des objets scientifiques questionnés par les Sciences de l’Information et de la Communication : la connaissance, les dispositifs sociotechniques et l’Intelligence Collective. Fruits d’une observation participante, deux cas pratiques issus du terrain GRDF sont exposés et analysés tout au long de ce travail de recherche : la co-construction d’un dispositif sociotechnique (le projet Tuilage) et l’émergence d’une Intelligence Collective autour du système d’information de GRDF avec la communauté Hack@demy. Complémentaires, ces deux projets interrogent l’organisation sous le prisme info-communicationnel. Ils mettent en exergue l’évolution de l’organisation
This research conducted within the national gas distributor in France GRDF combines sociotechnical and Collective Intelligence in order to question the company’s ability to be self-constructed by its employees trought the concept of organizational experience. These corporate’s transformations respond to trends in the energy sector (ecological transition) and to the employees’ expectations. The organization tends towards a so call meta-organization.After presenting the hybridity of the studied organization, its inscription in the "Information Society", the emphasis is placed on Information and Communication Sciences’ objects: knowledge, sociotechnical devices and Collective Intelligence. Resulting of a participant observation, two cases studies from GRDF are presented and studied throughout this research: the co-construction of a sociotechnical system (project Tuilage) and the emergence of a Collective Intelligence, Hack@demy, inside the information system of the company. Complementary, these two projects use an info-communicational approach to highlight the evolution of the company

Ce travail de recherche vise à comprendre les enjeux de l’implémentation des outils numériques et du travail coopératif à l’école primaire en Espagne à travers la mise en place et l’analyse d’un dispositif info-communicationnel où la médiation du savoir à travers le numérique occupe une place primordiale. A partir d’éléments issus du cadre théorique visant le concept d’information, de connaissance, de savoir et de dispositif, nous analysons au sein de la mise en place d’un dispositif info-communicationnel les interactions entre savoir, information et connaissance en mobilisant le concept de médiation. Les échanges communicationnels et les processus informationnels qui ont lieu dans le dispositif visent à comprendre la manière dont les sujets construisent des connaissances à partir des savoirs scientifiques mis à leurs dispositions et manipulables sous forme d’informations numériques circulantes. Un élément technique du dispositif est la plateforme Google Classroom qui permet de faire des échanges communicationnels, d’accéder aux informations et de les partager quel que soit le moment ou le lieu d’accès. La construction de connaissances dans le dispositif se fait également via le travail coopératif considéré une méthodologie de travail qui s’appuie sur les bases des paradigmes constructives et socio-constructivistes et du modèle d’apprentissage connectivisme, puisque nous introduisons les TICE comme élément médiateur entre les sujets, l’enseignant et l’objet d’apprentissage. Vu la nature de cette recherche nous avons choisi une méthodologie qui fait partie du paradigme de l’interprétativisme, qui soutient l’idée que dans les sciences sociales il n’existe pas une séparation entre l’observateur et l’objet observé, aussi la connaissance peut seulement avoir lieu à travers un processus de compréhension. Nous cherchons à analyser les usages que les acteurs font des outils numériques et comment ils s’approprient des informations circulantes dans le dispositif mis en place pour construire des connaissances
This research work aims at understanding the challenges of the implementation of digital tools and cooperative work in primary school’s through the establishment and analysis of an information-communication device where the mediation of knowledge through the digital technology occupies a primordial place. Based on elements from the theoretical framework on the concept of information, knowledge, knowledge and device, we analyze among the establishment of an information-communication device the interactions between knowledge, information and knowledge by mobilizing the concept of mediation. The communication exchanges and informational processes that take place in the device aim at observing the way in which subjects build knowledge from the scientific knowledge put at their disposal and manipulated in the form of circulating digital information. The Google Classroom platform that allows for communicative communication, access to information and information sharing regardless of when or where to access. The construction of knowledge in the device is done through cooperative work as a methodology of work which relies on the bases of constructive and socio-constructivist paradigms and the model of learning connectivism, since we introduce the ICST as mediating element between subjects, the teacher and the learning object. Given the nature of this research we have chosen a methodology that is part of the paradigm of interpretativism, which supports the idea that in the social sciences there is no separation between the observer and the observed object, and the knowledge can only take place through a process of understanding. Through this experience we seek to analyse the uses that actors make of digital tools and how they appropriate information circulating in the devices put in place to build knowledge
Este trabajo de investigación tiene como objetivo comprender los desafíos de la implementación de herramientas digitales y el trabajo cooperativo en la escuela primaria en España a través de la puesta en práctica y el análisis de un dispositivo de información-comunicación donde la mediación del saber a través de la tecnología digital ocupa un lugar primordial. Basándonos en elementos del marco teórico sobre el concepto de información, conocimiento, saber y dispositivo, analizamos a través del establecimiento de un dispositivo de información y comunicación las interacciones entre conocimiento, información y saber movilizando el concepto de mediación. Los intercambios de comunicación y los procesos informativos que tienen lugar dentro del dispositivo tienen como objetivo observar la manera en que los sujetos desarrollan el conocimiento a partir de la manipulación de la información digital de los saberes científicos puestos a su disposición. Un elemento del dispositivo que elimina las barreras de tiempo y espacio es la plataforma Google Classroom que permite la comunicación, el acceso y el intercambio de información, independientemente del momento o del lugar de acceso. La construcción del conocimiento en el dispositivo se realiza a través del trabajo cooperativo como una metodología de trabajo que se basa en los paradigmas constructivistas y socio-constructivistas y del modelo conectivista del aprendizaje, ya que incluimos las TIC como elemento mediador entre los saberes, el profesor y los objetos de aprendizaje. Dada la naturaleza de esta investigación, hemos elegido una metodología que forma parte del paradigma interpretativista, que apoya la idea de que en las ciencias sociales no hay separación entre el observador y el objeto observado, y el conocimiento solo puede tener lugar a través de un proceso de comprensión. Mediante el estudio de caso no buscamos encontrar conclusiones o resultados generalizables, sino profundizar nuestro conocimiento del caso estudiado. A través de esta experiencia, buscamos analizar los usos que los actores hacen de las herramientas digitales y cómo se apropian de la información que circula en el dispositivo implementado para generar conocimiento

Agriculture activity monitoring needs to deal with large amount of data originated from various organizations (weather station, agriculture repositories, field management, farm management, universities, etc.) and mass people. Therefore, a scalable environment with flexible information access, easy communication and real time collaboration from all types of computing devices, including mobile handheld devices as smart phones, PDAs and iPads, Geo-sensor devices, and etc. are essential. It is mandatory that the system must be accessible, scalable, and transparent from location, migration and resources. In addition, the framework should support modern information retrieval and management systems, unstructured information to structured information processing (IBM Info Stream, text analytic, pig & hive, etc.), task prioritization, task distribution (Hadoop), workflow and task scheduling system, processing power and data storage (Amazon S3 and Google BigTable). Thus, High Scalability Computing (HSC) or Cloud based system can be a prominent and convincing solution for this circumstance.

The purpose of this chapter is to propose a conceptual framework for implementation of advance info-communication technology and systems (ICT&S) across maritime cluster in emerging environments, with emphasis on some South-East European countries and South Africa. Smart implementation and adoption of the ICT&S in shipping and port management have been considered due to the Holtham’s & Courtney\'s model (2010). Furthermore, particular attention is given to Blockchain-based Maritime Supply Chain System (BMSCS) conceptual model, which includes distributed relational database, smart contracts, and crypto-currency payment mechanism as main constructs. The document workflow management, financial processes, and device connectivity are considered as key scenarios in the blockchain model. The stakeholders, who play the role of traditional intermediaries in the goods and accompanied documents and data flows, including overall supervision of the processes between end nodes, that is, shippers and customers, are encompassed within the BMSCS scheme. Some strengthens and frailty of BMSCS are highlighted, along with the suggestions for further investigation in this field, with the aim of better understanding prospective benefits and challenges of blockchain more extensive deployment across maritime sector in the future, with emphasize on developing environments.
