This paper proposes a generic and unified model of the power flow (PF) problem for multiterminal hybrid AC/DC networks. The proposed model is an extension of the standard AC-PF. The DC network is treated as an AC one and, in addition to the Slack, PV and P ...
For the development of a DEMOnstration Fusion Power Plant the design of auxiliary heating systems is a key activity in order to achieve controlled burning plasma. The present heating mix considers electron cyclotron resonance heating (ECRH), neutral beam i ...
Cyber-physical systems (CPSs) are real-world processes that are controlled by computer algorithms. We consider CPSs where a centralized, software-based controller maintains the process in a desired state by exchanging measurements and setpoints with proces ...
Live update is a promising solution to bridge the need to frequently update a software system with the pressing demand for high availability in mission-critical environments. While many research solutions have been proposed over the years, systems that all ...
This paper presents a model for estimation of average travel time on signalized urban lane using cumulative plots. The plots are generated based on the availability of data: a) case-D, for detector data only; b) case-DS, for detector data and signal timing ...
This dissertation deals with the design of practical erasure codes for storage systems. Hardware and logical disk failures are a common source of system failures that may lead to data loss. Nevertheless, it is predicted that spinning disks would remain the ...
Failures of any type are common in current datacenters, partly due to the higher scales of the data stored. As data scales up, its availability becomes more complex, while different availability levels per application or per data item may be required. In t ...
Nowadays, networked computers are present in most aspects of everyday life. Moreover, essential parts of society come to depend on distributed systems formed of networked computers, thus making such systems secure and fault tolerant is a top priority. If t ...
Manageability directly influences a system's reliability, availability, security, and safety, thus being a key ingredient of system dependability. Alas, we do not have today a good way to measure manageability or reason quantitatively about it, and this is ...
Nowadays, computers are the indispensable part of our life. They evolve rapidly and are more and more versatile. Computer networks made the remote corners of the world just a click away. But unavoidably, any software and hardware component is subject to fa ...
