Comparison of fully non-stationary artificial accelerogram generation methods in reproducing seismicity at a given site
2020
Abstract Seismic input modelling is a crucial step when Non-Linear Time-History Analyses (NLTHAs) are performed, the seismic response of structures being highly responsive to the input employed. When natural accelerograms able to represent local seismicity are not available, the use of generated accelerograms is an efficient solution for input modelling. The aim of the present paper is to compare four methods for generating fully non-stationary artificial accelerograms on the basis of a target spectrum, identified using seven recorded accelerograms registered in the neighbourhood of the construction site during a single event, assumed as target accelerograms. For each method, seven accelero…

The minimum mean cycle-canceling algorithm for linear programs
2022
Abstract This paper presents the properties of the minimum mean cycle-canceling algorithm for solving linear programming models. Originally designed for solving network flow problems for which it runs in strongly polynomial time, most of its properties are preserved. This is at the price of adapting the fundamental decomposition theorem of a network flow solution together with various definitions: that of a cycle and the way to calculate its cost, the residual problem, and the improvement factor at the end of a phase. We also use the primal and dual necessary and sufficient optimality conditions stated on the residual problem for establishing the pricing step giving its name to the algorith…
DESDEO : An Open Framework for Interactive Multiobjective Optimization
2018
We introduce a framework for interactive multiobjective optimization methods called DESDEO released under an open source license. With the framework, we want to make interactive methods easily accessible to be applied in solving real-world problems. The framework follows an object-oriented software design paradigm, where functionalities have been divided to modular, self-contained components. The framework contains implementations of some interactive methods, but also components which can be utilized to implement more interactive methods and, thus, increase the applicability of the framework. To demonstrate how the framework can be used, we consider an example problem where the pollution of…
The Challenge of Coexistence in Socially Vulnerable Schools
2017
Abstract Society in general and schools in particular continue to express their concerns with regard to the many challenges posed nowadays by living in a globalized world, where learning to coexist involves knowing oneself and those around us. Therefore, the professionals from the education sector and specially from the most vulnerable contexts demand the necessity to know strategies and initiatives which enable them to build a democratic school, where learning to coexist is the key to educate engaged citizens living in an increasingly intercultural, changing world. The study presented here has been conducted in two differentiated, but complementary, phases. During the first phase a documen…
Connecting theories of cascading disasters and disaster diplomacy
2018
Abstract Disaster diplomacy examines how and why disaster-related activities (disaster risk reduction and post-disaster actions) do and do not influence peace and conflict processes, especially whether or not a causal chain can be established between dealing with disaster risk or a disaster and outcomes in peace or conflict. Cascading disasters might provide a useful theoretical framing for mapping out causal pathways for disaster diplomacy. In conceptually exploring the intersection between disaster diplomacy and cascading disasters, this paper concludes that both disaster diplomacy and cascading disasters have limitations because they try to develop focused causal chains which, when exami…
The organization of the defense support system: an economic geography perspective
2017
In the context of restricted budgetary resources and the growing cost of maintenance, repair, and overhaul (MRO) activities, a major issue for modern armed forces is to sustain defense platforms. A possible method consists of realizing economies of scale through the concentration of maintenance activities, which involves the spatial reorganization of existing industrial sites dedicated to MRO. This article provides a formalized framework to discuss the optimal organization for the MRO of defense platforms in space. The public planner organizes the maintenance of defense platforms with only two possible spatial configurations. In the dispersed configuration, two industrial production units i…
Visualization of Exchanged Information with Dynamic Networks: A Case Study of Fire Emergency Search and Rescue Operation
2017
To perform emergency response activities, complex networks of emergency responders from different emergency organizations work together to rescue affected people and to mitigate the property losses. However, to work efficiently, the emergency responders have to rely completely on the data which gets generated from heterogeneous data sources during search and rescue operation (SAR). From this abundant data, rescue teams share needed information which is hidden in the abundant data with one another to make decisions, obtain situational awareness and also to assign tasks. Moreover, understanding and analyzing the shared information is a complex and very challenging task. Therefore, in this pap…
