Next Generation Air Traac Management will allow for the possibility of free ight, in which each aircraft chooses its own optimal route, altitude and speed. In a free ight environment, the trajectories of several aircraft may be connicting, in which case aircraft may or may not cooperate in resolving the connict. This paper presents a method for noncooperative connict resolution in which each ai...

Air Traac Management (ATM) of the future allows for the possibility of free ight, in which aircraft choose their own optimal routes, altitudes, and velocities. The safe resolution of trajectory connicts between aircraft is necessary to the success of such a distributed control system. In this paper, we present a method to synthesize provably safe connict resolution maneuvers. The method models ...

The Spanish Building Technical Code (CTE) sets that all new and restored buildings meeting its requirements have nearly zero energy consumption. This code is based on establishing limit values according to the climate zone. However, previous studies shown both existence of inequalities among regions limitations related direct application these criteria. work analyses classification included in ...

statement of the problem: the survival of pulpless teeth restored with different post and core systems is still a controversial issue. purpose: this study compared the retention of two different post and core systems and also the fracture resistance of teeth restored with these systems. material and method: eighty endodontically treated maxillary central incisors were sectioned perpendicular to...

Managed realignment is the landward relocation of flood infrastructure to re-establish tidal exchange on formerly reclaimed land. can be seen as a nature-based defence system that combines protection by realigned dike (artificial) and restored saltmarshes (nature-based). So far, research coastal managed primarily directed saltmarsh restoration This study focuses dikes. The aim this characterize...

tooth fracture is a common dental problem. by extension of cavity dimensions, the remaining tooth structure weakens and occlusal forces may cause tooth fracture. the aim of this study was to evaluate and compare the fracture resistance of teeth restored with direct and indirect composite restorations.sixty-five sound maxillary premolar teeth were chosen and randomly divided into five groups eac...

objective: resistance to fracture is a critical issue when it comes to tooth restoration. the purpose of this study was to evaluate the fracture resistance of pulpotomized primary molars restored with glass ionomer (gi), amalgam and composite resin with and without cusp reduction.   methods: in this in-vitro experimental study, 60 extracted primary teeth were randomly divided into 6 groups of 1...
