Subject: Abused children in Czech republic - law aspects of abused children, phenomenon. In my master thesis I focused my mind on the CAN syndrome. The work has two parts: theory and research. In the theoretical part I describe the CAN syndrome, its possible impact on child's general development and last but not least what legislation offers for solving this problem. In the research part I used interviews with 200 people to find out public knowledge about his phenomenon, what is their attitude to this problem and what solutions they can think of. The results of the research are described and supplanted by graphs.

La complexité des architectures de communication avioniques ne cesse de croître avec l’augmentation du nombre des terminaux interconnectés et l’expansion de la quantité des données échangées. Afin de répondre aux besoins émergents en terme de bande passante, latence et modularité, l’architecture de communication avionique actuelle consiste à utiliser le réseau AFDX (Avionics Full DupleX Switched Ethernet) pour connecter les calculateurs et utiliser des bus d’entrée/sortie (par exemple le bus CAN (Controller Area Network)) pour connecter les capteurs et les actionneurs. Les réseaux ainsi formés sont connectés en utilisant des équipements d’interconnexion spécifiques, appelés RDC (Remote Data Concentrators) et standardisé sous la norme ARINC655. Les RDCs sont des passerelles de communication modulaires qui sont reparties dans l’avion afin de gérer l’hétérogénéité entre le réseau cœur AFDX et les bus d’entrée/sortie. Certes, les RDCs permettent d’améliorer la modularité du système avionique et de réduire le coût de sa maintenance; mais, ces équipements sont devenus un des défis majeurs durant la conception de l’architecture avionique afin de garantir les performances requises du système. Les implémentations existantes du RDC effectuent souvent une translation direct des trames et n’implémentent aucun mécanisme de gestion de ressources. Or, une utilisation efficace des ressources est un besoin important dans le contexte avionique afin de faciliter l’évolution du système et l’ajout de nouvelles fonctions. Ainsi, l’objectif de cette thèse est la conception et la validation d’un RDC optimisé implémentant des mécanismes de gestion des ressources afin d’améliorer les performances de l’architecture de communication avionique tout en respectant les contraintes temporelles du système. Afin d’atteindre cet objectif, un RDC pour les architectures réseaux de type CAN-AFDX est conçu, intégrant les fonctions suivantes: (i) groupement des trames appliqué aux flux montants, i.e., flux générés par les capteurs et destinés à l’AFDX, pour minimiser le coût des communication sur l’AFDX; (ii) la régulation des flux descendants, i.e., flux générés par des terminaux AFDX et destinés aux actionneurs, pour réduire les contentions sur le bus CAN. Par ailleurs, notre RDC permet de connecter plusieurs bus CAN à la fois tout en garantissant une isolation entre les flux. Par la suite, afin d’analyser l’impact de ce nouveau RDC sur les performances du système avionique, nous procédons à la modélisation de l’architecture CAN-AFDX, et particulièrement le RDC et ses nouvelles fonctions. Ensuite, nous introduisons une méthode d’analyse temporelle pour calculer des bornes maximales sur les délais de bout en bout et vérifier le respect des contraintes temps-réel. Plusieurs configurations du RDC peuvent répondre aux exigences du système avionique tout en offrant des économies de ressources. Nous procédons donc au paramétrage du RDC afin de minimiser la consommation de bande passante sur l’AFDX tout en respectant les contraintes temporelles. Ce problème d’optimisation est considéré comme NP-complet, et l’introduction des heuristiques adéquates s’est avérée nécessaire afin de trouver la meilleure configuration possible du RDC. Enfin, les performances de ce nouveau RDC sont validées à travers une architecture CAN-AFDX réaliste, avec plusieurs bus CAN et des centaines de flux échangés. Différents niveaux d’utilisation des bus CAN ont été considérés et les résultats obtenus ont montré l’efficacité de notre RDC à améliorer la gestion des ressources du système avionique tout en respectant les contraintes temporelles de communication. En particulier, notre RDC offre une réduction de la bande passante AFDX allant jusqu’à 40% en comparaison avec le RDC actuellement utilisé. / The aim of my thesis is to provide a resources-efficient gateway to connect Input/Output (I/O) CAN buses to a backbone network based on AFDX technology, in modern avionics communication architectures. Currently, the Remote Data Concentrator (RDC) is the main standard for gateways in avionics; and the existing implementations do not integrate any resource management mechanism. To handle these limitations, we design an enhanced CAN-AFDX RDC integrating new functions: (i) Frame Packing (FP) allowing to reduce communication overheads with reference to the currently used "1 to 1" frame conversion strategy; (ii) Hierarchical Traffic Shaping (HTS) to reduce contention on the CAN bus. Furthermore, our proposed RDC allows the connection of multiple I/O CAN buses to AFDX while guaranteeing isolation between different criticality levels, using a software partitioning mechanism. To analyze the performance guarantees offered by our proposed RDC, we considered two metrics: the end-to-end latency and the induced AFDX bandwidth consumption. Furthermore, an optimization process was proposed to achieve an optimal configuration of our proposed RDC, i.e., minimizing the bandwidth utilization while meeting the real-time constraints of communication. Finally, the capacity of our proposed RDC to meet the emerging avionics requirements has been validated through a realistic avionics case study.

Avec l’apparition des nouvelles technologies de communication, le nombre des systèmes embarqués avionique et automobile est en constante augmentation. La gestion des communications entre ces systèmes devient alors de plus en plus complexe à mettre en oeuvre dans un contexte où les contraintes temporelles et environnementales sont très fortes et où le taux d’échanges de messages en augmentation continuelle. L’utilisation optimale des réseaux pour acheminer les données tout en respectant les contraintes temporelles imposées est essentielle du point de vue de la sûreté de fonctionnement. Historiquement, pour répondre aux problématiques d’efficacité et de sûreté, les industriels ont développé une palette de réseaux embarqués dédiés à leurs applications cibles (CAN, LIN, . . . ). Ces réseaux présentaient des débits relativement faibles à un moment où un besoin croissant en bande passante se faisait ressentir. le choix d’utiliser le concept de composants dit ‘sur étagères’ (off the shelf COTS) permettait alors de pallier à ce nouveau besoin. Dans un souci de conservation des capacités des réseaux à garantir les contraintes temporelles imposées par les systèmes embarqués temps réel, les industriels ont dû adapter ce concept de composants sur étagères aux systèmes embarqués. L’intérêt de l’utilisation de ces composants est un gain non négligeable en bande passante et en poids pour des coûts de développements relativement faibles. L’introduction de ces composants nouveaux s’est faite de telle sorte que leur impact sur les standards préexistants et les systèmes connectés soit minimal. C’est ainsi que les réseaux dit ‘hétérogènes’ ont vu leur apparition. Ces réseaux constituent une hybridation entre les technologies embarquées historiques et les composants sur étagère. Ils consistent en des réseaux d’extrémité utilisant des technologies éprouvées (telles que le CAN) interconnectés via des passerelles à un réseau fédérateur (backbone) utilisant des composants sur étagères. Dès lors, le défi majeur à relever lors de l’utilisation d’un réseau fédérateur est de respecter les contraintes temporelles des applications sollicitant les différents réseaux. L’objectif est mis à mal sur les points d’interconnexion des réseaux hétérogènes (Passerelles). Ainsi l’approche principale utilisée pour le passage d’un réseau à un autre est l’encapsulation de trames. Pour atteindre l’optimalité de performance de cette technique plusieurs paramètres sont à prendre en compte tels que le nombre de trames à encapsuler, les ordonnancements utilisés, le coût en bande passante ainsi que l’impact sur les distributions de délais (gigue). Dans l’optique de préservation des performances des réseaux, l’objet de nos travaux porte sur l’étude, la comparaison et la proposition de techniques permettant l’interconnexion de réseaux hétérogènes temps réels à la fois pour des applications à faibles et à fortes contraintes temporelles. Après un état de l’art sur les réseaux temps réel, nous spécifions différentes techniques d’interconnexion de réseaux hétérogènes, puis, nous présentons une étude de cas basée sur une architecture réseau interconnectant différents bus CAN via un réseau fédérateur sans fil Wi-Fi. L’étude que nous avons menée montre, par le biais de différentes simulations, que cette architecture réseau est une bonne candidate pour la transmission de flux à contraintes temporelles faibles. Une architecture réseau interconnectant différents bus CAN via un réseau fédérateur Ethernet commuté est ensuite considérée dans une seconde étude de cas ciblant les applications à fortes contraintes temporelles. Dans un premier temps, nous prenons en compte le cas d’un réseau fédérateur Ethernet-PQSE et, dans un second temps, le cas d’Ethernet-AVB. Cette étude nous permet de montrer l’impact des différentes techniques d’interconnexion sur les délais des flux du réseau. / With the emergence of new communication technologies, the number of avionics and automotive embedded systems is constantly increasing. The management of communications between these systems becomes increasingly complex to implement in a context where temporal and environmental constraints are very strong and where messages exchange rate is continuously increasing. The optimal use of networks to transmit data while fulfilling the imposed temporal constraints is essential from a safety point of view. Historically, in order to address safety and efficiency issues, manufacturers have developed a range of embedded networks dedicated to their target applications (CAN, LIN, . . . ). These networks have relatively low bit rates at a point of time where a growing need for bandwidth was felt. To overcome this new need, the choice of using the concept of so-called ’off-theshelf’ components (COTS) has been made. In order to preserve the networks abilities to guarantee the temporal constraints imposed by the real time embedded systems, manufacturers had to adapt the concept of off-the-shelf components to embedded systems. The benefits of using these components is a non-negligible gain in bandwidth and weight for relatively low development costs. The introduction of these new components has been made in such a way that their impact on pre-existing standards and connected systems is minimal. thereby, so-called ’heterogeneous’ networks have emerged. These networks are a hybridization of historical embedded technologies and off-the-shelf components. They consist of stub networks using proven technologies (such as CAN) interconnected via gateways to a backbone network using off-the-shelf components. Thus, the major challenge while using a heterogeneous network is to respect the temporal constraints of the applications requesting the different parts of the networks. This objective can be damaged at the interconnection points of the heterogeneous networks (Gateways). The main used approach to pass frames from one network to another is the encapsulation. To achieve the optimum performances of this technique, several parameters have to be considered such as the number of frames encapsulated, the used scheduling policy, the bandwidth cost as well as the impact on delay distributions (jitter). In order to preserve networks performances, the aim of our work is to study, compare and propose techniques ennabling the interconnection of real-time heterogeneous networks for application with both soft and hard temporal constraints. After a state of the art on real-time networks, we have specified different techniques for the interconnection of heterogeneous networks, then we have presented a case study based on a network architecture interconnecting different CAN buses via a wireless backbone network (Wi-Fi ). The study we conducted shows, through various simulations, that this network architecture is a good contender for the transmission of flows with soft temporal constraints. A network architecture interconnecting different CAN busses via a switched Ethernet backbone is considered in a second case study targeting applications with hard temporal constraints. Two different Ethernet backbone networks are taken into account. We studied first, the case of a switched Ethernet-PQSE backbone network. Then the case of a switched Ethernet-AVB backbone is considered. This study enabled us to highlight the impact of the different used interconnection techniques on network flows delays.

Occurrence of Child Abuse and Neglect (CAN) has recently become quite frequent. Even though the number of experts dealing with this issue is increasing and there is a lot of professional literature available, the numbers of children abused and neglected are on increase. Traumas and pathological behaviour, which children experience in their families, are often carried over to adulthood and new families in the form of behavioural patterns. Basic school teachers, who spend substantial part of the day with children in the classes, play an important role not only in prevention, but also in detecting CAN cases. The objective of the diploma thesis was to observe the level of awareness among teachers regarding CAN and related issues and to find out whether they know what to do in case a child is suspected of being abused or neglected. Also, it was aimed at learning whether the awareness is influenced by microregion the teachers live in and respondents? age. The hypotheses were established to observe whether the teachers of basic schools in Jindřichův Hradec have better awareness of the issues relating to CAN than the teachers of basic schools in Třeboň, and whether the teachers of basic schools in Jindřichův Hradec have better awareness of the issues relating to CAN than the teachers of basic schools in Dačice. Next hypothesis dealt with whether basic school teachers under 40 years of age demonstrate better CAN awareness than teachers above 40 years of age. A quantitative research using the method of interview and technique of questionnaire was used to verify the hypotheses. The research corpus comprised of teachers of basic schools in the microregions of Dačice, Jindřichův Hradec and Třeboň. The finite corpus comprised of 193 respondents. The teachers of basic schools in the microregion of Jindřichův Hradec did not demonstrate better awareness of the issues relating to CAN than the teachers of basic schools the microregions of Třeboň and Dačice. Also, the teachers under 40 years of age did not demonstrate better awareness of the issues at hand than the teachers above 40 years of age. Analysis of the outcomes retrieved from the performed research did not confirm validity of the hypotheses H1, H2 and H3. The outcomes of the thesis imply that awareness of the basic school teachers, who were included in the research corpora in the given microregions, regarding the issues relating to CAN do not relate either to given microregions, where teachers work, or the age of the respondents. In general, respondents showed substantial awareness of CAN. It should be noted that CAN is very serious social problem and each society should pay proper attention to it.

Tratando-se de redes de transdutores cabeadas, as redes CAN (Controller Area Network) são utilizadas em automóveis modernos, instrumentação médica, em veículos táticos, na automação de processos, no transporte metropolitano e em sistemas de controle de fábricas. A maioria das estruturas críticas de sistemas de controle fazem uso do CAN em algum ponto na rede, para conectar sensores que se encontram distantes e controlar atuadores de um sistema, ou para conectar vários controladores que utilizam uma interface em comum. O padrão sem fio, IEEE 802.15.4, comercialmente conhecido como “ZigBee”, foi projetado para operar em baixas taxas de dados, com segurança e facilidade de configurações de rede. Esta tese tem como objetivo desenvolver um sistema heterogêneo utilizando microcontroladores ATMEGA em que, o modelo do protocolo CAN e o padrão IEEE 802.15.4 estejam acoplados. Este módulo será capaz de gerenciar e monitorar sensores e atuadores utilizando CAN e, através do padrão sem fio 802.15.4, comunicar-se com os outros módulos da rede. O interfaceamento entre os pacotes da rede de controle de área (CAN) com a rede ZigBee é realizado através da implementação de tabelas de dispersão (Hash Tables) para o gerenciamento e otimização da memória utilizada. As análises realizadas de tempo de inserção, remoção e comunicação de dados, com o auxílio da técnica computacional de tabelas de dispersão para o armazenamento das informações, mostram que este procedimento favorece a comunicação entre os protocolos de redes industriais com os protocolos de redes sem fios. A economia de memória do microcontrolador com a utilização das tabelas de dispersão proposta nesta tese chegou a ser em média 750% superior do que as que não se utilizam das tabelas de dispersão. / The use of wireless communication networks is not an optional tool and become a requirement in automated systems, such as monitoring home, automobiles, automated process control and communication between people. In another aspect, wired networks, such as CAN networks, are used in modern automobiles, medical instrumentation, tactical vehicles, process automation, metropolitan transport and manufactory control systems. Many critical structures in control system use CAN network at some point, to connect sensors that are far away and to control system actuators, or to connect several controllers that use a common interface. The wireless IEEE standard 802.15.4, commercially known as “ZigBee”, is designed to operate at low data transfer rates, with security and facility of network configurations. This thesis aims to develop a heterogeneous system using ATMEGA microcontrollers in which the CAN protocol model and the IEEE standard 802.15.4 are coupled. This module is capable of managing and monitoring sensors and actuators using CAN and, through the IEEE standard 802.15.4, communicating with the other modules in network. The interface between the CAN network packets with the ZigBee network is performed through the implementation of Hash Tables to manage and optimize the memory used. The analysis of time of insertion, delete and data communication, with the aid of the computational technique of hash tables for the storage of information, show that this procedure favors the communication between the protocols of industrial networks with protocols of wireless networks . The memory economy of the microcontroller with the the hash tables proposed in this thesis was on average 750% higher than those without the hash tables.

É apresentada uma metodologia para descrever o mapa de desempenho (ou mapa de consumo de combustível) de um motor de combustão interna como função de suas condições de operação (rotação e torque) baseados em medições embarcadas. É utilizada para este levantamento a combinação de medições via GPS (para a velocidade longitudinal e inclinação de pista) e OBD-II para aquisição de sinais da rede CAN, como rotação do motor e consumo de combustível. É desenvolvida uma metodologia para o cálculo do torque líquido do motor baseado na medição de velocidade e aceleração longitudinal do veículo com uma margem de incerteza de 2% a 5% no cálculo do torque em condições normais de operações. É realizado um detalhamento da origem das incertezas para avaliar a contribuição individual de cada parâmetro. Um modelo de regressão polinomial é utilizado para descrever o mapa de consume de combustível do motor cujos coeficientes característicos são determinados experimentalmente através da metodologia proposta para cinco veículos diferentes a fim de comprovar a eficácia da metodologia. Os coeficientes de correlação variam de 0.797 a 0.997, sendo que em três de cinco veículos o coeficiente de correlação é maior que 0.910, comprovando a robustez da metodologia. / It is presented a methodology to describe the engine performance map (or the engine fuel map) for an internal combustion engine as a function of its operating conditions (engine speed and torque) based on on-board measurements. It is used a combination of GPS measurements for vehicle speed and road grade together with a OBD-II acquisition system in order to acquire information provided by CAN network, such as engine speed and fuel consumption. A methodology to calculate the engine torque based on speed and acceleration measurements is shown with an average uncertainty in the range of 2% to 5% for torque calculation in normal operating conditions. It is presented a detailed breakdown of the contribution of individual parameters in torque calculation uncertainty. A polynomial regression model to describe the engine fuel map is presented and the coefficients for this model is calculated based on on-road measurements for 5 different vehicles to prove the accuracy of the proposed methodology. The correlation coefficients obtained for these measurements are within the range of 0.797 to 0.997 and three out of five vehicles with correlation coefficient higher than 0.910, proving the methodology robust.

Course: Master Thesis in Business Administration Institution: Business School at Linneus University in Växjö Authors: Nadja Muftic and Donika Ombashi Supervisor: Karin Jonnergård Examiner: Fredrik Karlsson Title: Integrated reporting  - The glass half full or half empty? Background: Integrated reporting is the latest framework in the reporting world and intends to integrate financial and non-financial information into one single report. Through the <IR> framework, the integrated report aims to describe how business strategies, corporate governance and performance create value over short, medium and long-term perspective. The integrated report has gained enthusiasm and attention in media and among experts in Sweden. Despite the good presentation of integrated reporting, there are only a few companies in Sweden that publish integrated reports in accordance with the <IR> framework. The discourse, the overall discussion, about the phenomenon is therefore interesting to examine among companies in Sweden. Purpose: The purpose of this thesis is to study the discourse of integrated reporting among experts in Sweden and the relevance of the discourse amongst Swedish companies. Furthermore, we also intend to explain the circumstances that affect the relevance between the discourse and the companies. Method: This thesis consists of two studies; a first study that examines the discourse on integrated reporting developed by experts in Sweden and a second study that examines the relevance of the discourse amongst Swedish companies. A qualitative approach is the basis of the two studies, in which the collected material has been obtained through semi-structured interviews. The expert’s discourse has been processed through a critical discourse analysis and the material from the companies has been processed through a content analysis. Conclusion: The conclusion is that the discourse has a low relevance amongst companies in Sweden at the moment. However, the identified circumstances that explain the relevance indicate that the phenomenon may spread more in the future. / Kurs: Examensarbete Civilekonomprogrammet Lärosäte: Linnéuniversitetet i Växjö Författare: Nadja Muftic och Donika Ombashi Handledare: Karin Jonnergård Examinator: Fredrik Karlsson Titel: Integrerad rapportering – Glaset halvfullt eller halvtomt? Bakgrund: Integrerad rapportering är det senaste inom rapporteringsvärlden och avser att integrera finansiell- och icke finansiell information till en enskild rapport. Genom ramverket <IR> ämnar den integrerade rapporteringen beskriva hur företagsstrategier, styrning och prestationer skapar värde över kort, medellång, och lång sikt. Den integrerade rapporteringen har erhållit entusiasm och uppmärksamhet i media och bland experter i Sverige. Trots den goda framställningen av integrerad rapportering finns det idag i Sverige ett fåtal företag som publicerar integrerade rapporter enligt ramverket <IR>. Diskursen, den samlade diskussionen, kring fenomenet är därmed intressant att undersöka på företagsnivå. Syfte: Syftet med denna uppsats är att studera diskursen om integrerad rapportering bland experter i Sverige och vilken relevans diskursen har på företagsnivå. Vidare ämnar vi även förklara omständigheter som påverkar om det finns en relevans eller inte mellan diskurs och företag.               Metod: Denna uppsats utgörs av två studier; en första studie som undersöker den diskurs om integrerad rapportering som framkommit bland experter i Sverige och en andra studie som undersöker diskursens relevans på företagsnivå. En kvalitativ forskningsansats ligger till grund för båda studierna där det insamlade materialet har erhållits genom semistrukturerade intervjuer. Experternas diskurs har bearbetats genom en kritiskdiskursanalys och materialet från företagen har bearbetats med hjälp av en innehållsanalys. Slutsats: Slutsatsen dras att diskursen har en låg relevans på företagsnivå i Sverige i nuläget. De identifierade omständigheterna som förklarar relevansen tyder dock på att fenomenet kan få en större utbredning i framtiden.
