The Ocean Observatories Initiative (OOI) consists of seven research sites with over 800 instruments collecting ocean, seafloor, and meteorological data in the world's oceans, extending from the Irminger Sea to the Southern Ocean. The scale with which data are produced from the instruments and their platforms presents key challenges, including how to (1) build data and information management infrastructure...
Recently cloud computing markets have expanded, and there are various kind of services and their providers. How-ever, Security is the primary concern of cloud users. However, service providers are unaware precisely of the types of security countermeasures required for their cloud servers. A method to define what the type security required for each operator using two security patterns are proposed...
Remote laboratory creates a possibility to handle configuration, control and testing functions of the lab equipment through a client-server communication model. The solutions create conditions for virtual lab exercises organization within the e-learning service of Computer Engineering Laboratory at Technical University of Košice. This is a work with real logical system and functional computer units.
Configuration complexity is a novel research field.The concept of configuration complexity is outlined in this paper, as well as current research is introduced briefly. Based on the current study results and best practice, improved configuration complexity quantitative model is proposed in the paper. Then, after an enterprise network environment is constructed in the laboratory, the quantitative model...
Network operation complexity model is proposed in this paper. This model includes nested system model, operation process model and quantitative indicator model. Then, a normalization treatment method of indicator data is put forward. After constructing a network system in the laboratory, we apply the model to the operation process of network and obtain complexity indicator value through measuring...
