A practical approach for the strength evaluation of RC columns reinforced with RC jackets
2015
Abstract Reinforced concrete (RC) jacketing is nowadays one of the most common techniques adopted for seismic retrofitting of existing RC columns. It is used to increase load-carrying capacity and ductility of weak existing members by means of a simple and cheap method. The structural efficiency is related to two main effects: – the enlargement of the transverse cross section; – the confinement action provided by the external jacket to the inner core. Several theoretical and experimental studies were addressed in the past to investigate on how it is possible to calculate the strength enhancement due to these effects and to highlight the main key parameters influencing the structural behavio…
DSC: software tool for simulation-based design of control strategies applied to wastewater treatment plants.
2011
This paper presents a computer tool called DSC (Simulation based Controllers Design) that enables an easy design of control systems and strategies applied to wastewater treatment plants. Although the control systems are developed and evaluated by simulation, this tool aims to facilitate the direct implementation of the designed control system to the PC of the full-scale WWTP (wastewater treatment plants). The designed control system can be programmed in a dedicated control application and can be connected to either the simulation software or the SCADA of the plant. To this end, the developed DSC incorporates an OPC server (OLE for process control) which facilitates an open-standard communic…
H∞ static output-feedback control design with constrained information for offshore wind turbine system
2013
Abstract This paper deals with H ∞ static output-feedback control design with constrained information for offshore wind turbines. Constrained information indicates that a special zero–nonzero structure is imposed on the static output-feedback gain matrix. A practical use of such an approach is to design a decentralized controller for a wind turbine. This will also benefit the controller in such a way that it is more tolerant to sensor failure. Furthermore, the model under consideration is obtained by using the wind turbine simulation software FAST. Sufficient conditions to design an H ∞ controller are given in terms of Linear Matrix Inequalities ( LMI s ). Simulation results are given to il…
Welcome to MTI—A New Open Access Journal Dealing with Blue Sky Research and Future Trends in Multimodal Technologies and Interaction
2016
In this era of massive use of computers and other computational devices (e.g., low-cost wearable sensors, smartphones, other smart devices, etc.), the nature of digital data is becoming more complex and heterogeneous.
Event Reconstruction
2014
Event reconstruction is one of the most important step in digital forensic investigations. It allows investigators to have a clear view of the events that have occurred over time. Event reconstruction is a complex task which requires exploration of a large amount of events due to the pervasiveness of new technologies nowadays. Any evidence produced at the end of the investigative process must also meet the requirements of the courts, such as reproducibility, verifiability, validation, etc. After defining the most important concepts of event reconstruction, a survey of the challenges of this field and solutions proposed so far is given in this chapter. Irish Research Council Science Foundati…
An introduction to Open Source software licensing and use in anaesthesia department
2007
EU member states are supporting the Open Source initiative suggesting the adoption of free software in government installation instead of commercial software. The latest national laws suggest adoption of Open Source solutions in educational structures as well, such as in schools and universities. It is clear that imprisoning knowledge with license fees does not allow any improvement nor any growth.
GA-based Off-Line Parameter Estimation of the Induction Motor Model Including Magnetic Saturation and Iron Losses
2020
This paper, starting from recent papers in the scientific literature dealing with Rotating Induction Motor (RIM) dynamic modelling, as a first step, improves its space-vector dynamic model, including both the magnetic saturation and iron losses; The main original aspects of the proposed model are the following: 1) the magnetic saturation of the iron core has been described on the basis of both current versus flux and flux versus current functions, 3) it includes the iron losses, separating them in hysteresis and eddy current ones, 4) it includes the effect of the load on the magnetic saturation. Afterwards, it proposes an off-line technique for the estimation of electrical parameters of thi…
A comparative review of CASE shells: A preliminary framework and research outcomes
1993
Abstract Because of rigidity and weak support of the user's native methods and methodologies in existing CASE tools, there is a growing need for customizable CASE tools (CASE shells). The nature of CASE shells is different from ordinary CASE tools supporting a fixed set of methods. With CASE shells, organizations can define tools to support their own methods, instead of choosing a tool that supports them. Existing CASE shells have different features and architectural principles that make them appropriate for different tasks. Obviously, a framework for comparing them is needed. In this paper we develop one such framework. It takes into account different tasks in customization and the effecti…
New Forms of Work in the Light of Globalization in Software Development
2009
Globalization in software development introduced significant changes in the way organizations operate today. Software is nowadays produced by team members from geographically, temporally and culturally remote sites. Organizations seek for benefits that global market offers and face new challenges. Naturally resistant to change, these organizations often do not realize necessity for tailoring existing methods for distributed collaboration. Our empirical investigation shows a great variety in the ways organizations distribute responsibilities across remote sites and conclude that these can be divided into two main categories: joint collaboration that requires investments in team building and …
Startup Trust Model: The Role of Trust in Successful Software Startup
2017
the increasing desire by many for a better world and easier living conditions have contributed to various efforts to the frontiers of innovation in information technology (IT). The ensuing phenomena is the launch of many software startups to give meaning to such innovations in IT. Interestingly, the rate at which many of such startups fail is usually higher than expected. A collaborative effort by actors in IT innovation ecosystem has been posited to lead to a successful startup. However, there is the need for a trust model to ensure that the collaborative effort become meaningful. Through the lens of Morgan and Hunt's commitment trust theory, this study examines the antecedents of trust am…
