“…e) However, East Med's design may not only linked to geo-economic but also nationalsupranational and geopolitical balances. In this regard, Italy (Marseglia, Rivieccio, & Medaglia, 2018) has expressed concerns about the pipeline's route crossing its territory. Although Rome is officially invoking environmental concerns and arguments, the more profound interpretation of Italian maneuver (not a decision) highlights complex balances of Rome-Berlin, Paris, and Brussels relationships, as well as the ideological and political affinity of Salvini-Putin.…”

The “geopolitical complex” of Southeastern Europe, as a sub-system of the Europe-Asia-Middle East system, highlights its geo-economic dimension since the discovery of hydrocarbons in this geographical area has become a major geopolitical factor, resulting to competitions, conflicts, and strategic alliances among different actors/players. In this context, the particular space and time play an essential role, since the decision-making process has become a vital determinant of the necessary geostrategic synthesis under conditions of uncertainty and risk. This article approaches the subject under consideration by applying quantitative decision-making methods under uncertainty and/or limited uncertainty (risk) conditions by actors/players of the region; it examines the choice of alternative strategies that highlight not only the maximization of the actors’ geopolitical benefits but also provides added value to already formed strategic alliances. It also attempts to answer the question of how the construction of an LNG terminal can generate multiple benefits from its location and operation by presenting a theoretical model.

“…Actual civil structures are susceptible to the influence of varying environmental factors and operational conditions such as humidity, wind and moving vehicles, however the most important factor has proven to be temperature [1][2][3]. In recent years, structural health monitoring under environmental variations has become a popular research topic in the field of civil engineering [4][5][6]. Moaveni and Behmanesh [7] investigated the effects of changing ambient temperatures on finite element (FE) model updating of the Dowling Hall Footbridge.…”

To study the variations in modal properties of a reinforced concrete (RC) slab (such as natural frequencies, mode shapes and damping ratios) under the influence of ambient temperature, a laboratory RC slab is monitored for over a year, the simple linear regression (LR) and autoregressive with exogenous input (ARX) models between temperature and frequencies are established and validated, and a damage identification based on particle swarm optimization (PSO) is utilized to detect the assumed damage considering temperature effects. Firstly, the vibration testing is performed for one year and the variations of natural frequencies, mode shapes and damping ratios under different ambient temperatures are analyzed. The obtained results show that the change of ambient temperature causes a major change of natural frequencies, which, on the contrary, has little effect on damping ratios and modal shapes. Secondly, based on a theoretical derivation analysis of natural frequency, the models are determined from experimental data on the healthy structure, and the functional relationship between temperature and elastic modulus is obtained. Based on the monitoring data, the LR model and ARX model between structural elastic modulus and ambient temperature are acquired, which can be used as the baseline of future damage identification. Finally, the established ARX model is validated based on a PSO algorithm and new data from the assumed 5% uniform damage and 10% uniform damage are compared with the models. If the eigenfrequency exceeds the certain confidence interval of the ARX model, there is probably another cause that drives the eigenfrequency variations, such as structural damage. Based on the constructed ARX model, the assumed damage is identified accurately.

“…The growing concern surrounding the environmental impacts generated by the use of fossil fuel sources and global warming effects are causing an increasing interest in study and the optimization of the configurations of transport systems [1][2][3][4] and public transport network [5,6]. Planning urban rapid transit systems is a complex decision process that takes place over a long period and involves the participation of designers, engineers, politicians, and social committees.…”

Optimal Alignments for Designing Urban Transport Systems: Application to Seville

The achievement of some of the Sustainable Development Goals (SDGs) from the recent 2030 Agenda for Sustainable Development has drawn the attention of many countries towards urban transport networks. Mathematical modeling constitutes an analytical tool for the formal description of a transportation system whereby it facilitates the introduction of variables and the definition of objectives to be optimized. One of the stages of the methodology followed in the design of urban transit systems starts with the determination of corridors to optimize the population covered by the system whilst taking into account the mobility patterns of potential users and the time saved when the public network is used instead of private means of transport. Since the capture of users occurs at stations, it seems reasonable to consider an extensive and homogeneous set of candidate sites evaluated according to the parameters considered (such as pedestrian population captured and destination preferences) and to select subsets of stations so that alignments can take place. The application of optimization procedures that decide the sequence of nodes composing the alignment can produce zigzagging corridors, which are less appropriate for the design of a single line. The main aim of this work is to include a new criterion to avoid the zigzag effect when the alignment is about to be determined. For this purpose, a curvature concept for polygonal lines is introduced, and its performance is analyzed when criteria of maximizing coverage and minimizing curvature are combined in the same design algorithm. The results show the application of the mathematical model presented for a real case in the city of Seville in Spain.
