Continuous advancement of cloud technologies, alongside their ever increasing stability, adoption, and ease of use, has led to a rise in native cloud applications, possibly over a larger pool of heterogeneous resources or in multi-cloud approaches. This, in turn, brought unprecedented levels of complexity in the context of cloud computing. Such complexity may cause a series of events and incidents...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
With the ongoing advancements in Cloud Computing, new technologies and standards are being developed, ever increasing the complexity of this environment along with the associated risks, thus making it difficult for companies to take advantage of the benefits Cloud Computing brings without being exposed to them. Due to this increased complexity, there is an increased chance of a deviation from the...
In the case of unmanned aerial vehicles, for the variation of the elevator deflection there exists a safe interval, the interval for which steady longitudinal flight with constant forward velocity is present. As the elevator deflection is one of the control parameters, when the automated flight control system (AFCS) is decoupled and the value of δe is situated outside the safe interval...
This paper examines the cloud resources management for a multi-agent IoT architecture. The resources tenancy is a costly operation, thus their allocation and management should be approached in an effective manner. On the other hand, the infrastructure should not be affected by the deployment or maintenance life cycle, operations that could put parts of the system offline, or even the entire system...
The Internet of Things (IoT) is the enabler of major societal changes. As an integrated part of the Future Internet, it is based on a series of enabling technologies. In the context of the IoT, "smart things/objects" are becoming more important, active players with capabilities to communicate and interact one with the other and with IoT-enabled ecosystems. Semantic annotations, things/objects...
Flying quality analysis performed in a mathematical model of the flight, leads to results that can be tested against the experiments. Even for a simplified mathematical model, usually obtained by neglecting some influences and quantities which are assumed insignificant with respect to the others, the computational effort is quite large. The multi-agent system modeled in this paper exploits different...
The Semantic data is regarded as one of the best methods to describe relations between different data sources. The Semantic annotation of data improves the data aggregation methods because the relations are already defined. We have implemented a software prototype using Scala, Apache Jena and the Fuseki database server for handling a context modeled using a dynamic created ontology. For use cases...
With the current prevalence of Ubiquitous Computing, more specifically Internet of Things, almost every other appliance aims to exhibit smart behavior and expose it through internet connectivity, resulting in a plethora of sensors that expose environmental information online. As a direct result, large quantities of data are pouring online waiting to be processed. Our paper addresses this problem through...
If, during a longitudinal flight with constant forward velocity of an unmanned aerial vehicle (UAV), the automatic flight control system (AFCS) fails and the elevator deflection is not in the safe interval, then the flight becomes oscillatory. In this paper, the dependence of the period and the range of the oscillations of the pitch rate and angle of attack on the elevator deflection of the possible...
The maturation of Cloud Computing technologies, cumulated with the opportunities for Small and Medium Enterprises to migrate their activities into the Cloud, have led to new marketplaces where the competition with the large enterprises can be sustained through Platform-as-a-Service solutions combined with cloud Governance. Having a Cloud Governance solution that offers support for the services lifecycle,...

In the context of the efforts to organize the knowledge in the new and emerging area of Cloud Computing we performed an analysis of relevant existing developments and built on this basis a framework for a semantic registry of cloud services. The framework contains core ontological definitions and extension mechanisms used to define ontologies for cloud services, related to the aspects of semantic...
Recent migration towards the cloud has lead to boom of initiatives that address key issues related to it. One of these issues, integrating various available cloud services while providing automated lifecycle management, was addressed by cloud governance. However, while mostly until now computers and phones were linked to the internet, new devices like tablets, sensors, smart devices (embedded devices)...
The Internet, since its inception, has been continuously evolving, creating both problems and solutions. Recent trends show that an increasing number of uniquely identifiable things (objects, sensors and devices) are making their way to this medium.
Cloud adoption is consistent within IT-based industries at different maturity levels. While cloud migration is an ongoing process, its base characteristics are not yet fully exploited. As Cloud Governance is built on top of requirements like security, reliability, trust, portability, interoperability, or fail over, a highly distributed and concurrent, and fault tolerant solution is required in order...
Cloud governance's approach to development in the cloud environment allows for a way in which services are well defined and unambiguous, where they can be easily designed, implemented, deployed and executed, for a way in which they can be consumed. This approach is beneficial to SMEs which can now empower themselves by adopting cloud-based technologies and platforms. They now have the opportunity...
The dawn of Cloud Computing has opened new opportunities for IT-based industries, enabling them to cut costs and extend their businesses to a level which was previously hard to attain. While Cloud adoption is an ongoing process, many enterprises are still reluctant to pursue it because its downside outweighs its benefits, especially due to problems related to security and privacy. Coming from Service...
The emergence of cloud computing has created a shift in the service lifecycle, a shift meant to meet the requirements of cloud environments. Anticipating this, cloud governance, a step forward from SOA governance, tries to consolidate an environment where collaboration between various enterprises can be easily achieved. Cloud governance lays the groundwork for enabling easy application development...
A direct consequence of adopting Cloud Computing is the creation of new marketplaces for small and medium sized enterprises (SMEs). Having a strong support offered by Platform as a Service (PaaS) paradigm in terms of automation and management, combined with cloud governance, SMEs have a real chance to get back in competition with the large enterprises. The implementation of Cloud Governance solutions...
