Structured Network Public Spaces a Step Toward Integration of Urban
Network of public spaces composes of a network of interconnected land use and various elements of the city, such as synthetic and natural which shows the city as a whole. Network structure of public spaces is important because understanding this network as a structure presents us the formation of the city. This paper attempts to define the status of the network of public spaces in the city stru...
متن کاملA Step toward a Sustainable Diet by Reducing Carbon Footprint: A Case Study in Iran
Introduction: Greenhouse gas (GHG) emissions have caused environmental effects. Food production is one of the sources of GHGs. This study aimed to suggest dietary scenarios for decreasing GHG emissions. Materials and Methods: GHG emissions in the target population of Urmia city, Northwest Iran, were investigated using a modeling approach. Three dietary scenarios were modeled and analyzed to ev...
متن کاملSOLVING A STEP FIXED CHARGE TRANSPORTATION PROBLEM BY A SPANNING TREE-BASED MEMETIC ALGORITHM
In this paper, we consider the step fixed-charge transportation problem (FCTP) in which a step fixed cost, sometimes called a setup cost, is incurred if another related variable assumes a nonzero value. In order to solve the problem, two metaheuristic, a spanning tree-based genetic algorithm (GA) and a spanning tree-based memetic algorithm (MA), are developed for this NP-hard problem. For compa...
متن کاملA step toward systems metabolomics.
WHILE LEVELS OF GENES AND proteins provide information on a cell’s possibilities, the levels of metabolic intermediates provide a very direct indication of a cell’s current activities. Methods to monitor the levels of metabolites as well as the dynamic flux through metabolic pathways can be integrated to generate a systems-level understanding of the metabolic activity in a cell at a given time....
متن کاملdevelopments toward an ideal skin substitute: a commentary
skin grafting always has been considered a challenging task for the researchers and tissue engineers from its first introduction in 1871 by reverdin. skin substitutes, composed of degradable synthetic or biological components, are being considered as emergency replacements/grafts to the damaged skin. a number of technical developments in this filed have led to development of several skin substi...
