For decades, the Black Sea region has rarely been considered among most important strategic spaces in world; West not had a coherent strategy for region, and officials, experts academia have paid much attention to political security developments Sea. This attitude changed only after outbreak of war, which balance power threatened global architecture. Officials Europe United States finally recog...

As a tool for exploration of concealed coal seams by modern techniques, determination of the depth of erosion of coal seams with reference to the surface of angular unconformity underlying the remnants of a key bed is conducted for the first time in coal mines of Kerman region. The angular unconformity surface (the initial surface exposure of coal seams) separates the coal seams of Jurassic age...

Food losses refer to edible food mass decrease throughout the human food chain. Food losses occurring at consumption stage are called food waste. Food Losses and Waste (FLW) represent one of the most critical social, economic and ecological challenges facing humanity, besides being also an ethical issue. FAO data show that roughly one-third of food produced for human consumption is lost or wast...

The global Ocean-Land-Atmosphere Model (OLAM) model was used to estimate the impacts of the global oceanic warming on the climate projections for the 21st Century focusing on the South America region. This new model is able to represent simultaneously the global and regional scales using a refining grid approach for the region of interest. First, the model was run for a 31-year control period c...

[1] The Millennium Ecosystem Assessment scenarios for 2000 to 2050 describe contrasting future developments in agricultural land use under changing climate. Differences are related to the total crop and livestock production and the efficiency of nutrient use in agriculture. The scenarios with a reactive approach to environmental problems show increases in agricultural N and P soil balances in a...

In this paper the preliminary design of multiple gravity-assist trajectories is formulated as a global optimization problem. An analysis of the structure of the solution space reveals a strong multimodality, which is strictly dependent on the complexity of the model. On the other hand it is shown how an oversimplification could prevent finding potentially interesting solutions. A trajectory mod...

Large-scale network systems involve a large number of states, which makes the design of real-time controllers a challenging task. A distributed controller design allows to reduce computational requirements since tasks are divided into different systems, allowing real-time processing. This paper proposes a novel methodology for solving constrained optimization problems in a distributed way inspi...

In this work, we present an improved global logic-based outer approximation method (GLBOA) for the solution of nonconvex generalized disjunctive programs (GDP). The GLBOA allows the solution of nonconvex GDP models, and is particularly useful for optimizing the synthesis of process networks. Two enhancements to the basic GLBOA are presented. The first enhancement seeks to obtain feasible soluti...
