General information conditioned by a variable event
The aim of this paper is to present, by axiomatic way, an idea about the general conditional information of a single, fixed fuzzy set when the conditioning fuzzy event is variable. The properties of this conditional information are translated in a system of functional equations. Some classes of solutions of this functional system are founded
An independence property for general information
The aim of this paper was a generalization of independence propery proposed by Kampè de Fèriet and Forte in Information Theory withou probability, called "general infromation". Therefore, its application to fuzzy sets has been presented
General conditioned and aimed information on fuzzy setting
In this paper our investigation on aimed information, started in 2011, will be completed on fuzzy setting. Here will be given a form of information for fuzzy setting, when it is conditioned and aimed. This information is called "general", because it is defined without using probability or fuzzy measure
Analysis of the small oscillations of a system viscous liquid-barotropic gas in a container
The authors study the ssmall oscillations of a system viscous liquid-barotropic gas in a container. From the equations of motion and using two auxiliary problems, they reduce the problem to a sysstem of two operatorial equations in a suitable Hilbert space. They prove the existance of the spectrum
Pattern-Based Genetic Algorithm for Airborne Conflict Resolution
NASA has developed the Autonomous Operations Planner (AOP) airborne decision support tool to explore advanced air traffic control concepts that include delegating separation authority to aircraft. A key element of the AOP is its strategic conflict resolution (CR) algorithm, which must resolve conflicts while maintaining conformance with traffic flow management constraints. While a previous CR algorithm, which focused on broader flight plan optimization objectives as a part of conflict resolution, had successfully been developed, new research has identified the need for resolution routes the users find more acceptable (i.e., simpler and more intuitive). A new CR algorithm is presented that uses a combination of pattern-based maneuvers and a genetic algorithm to achieve these new objectives. Several lateral and vertical maneuver patterns are defined and the application of the genetic algorithm explained. A new approach to defining a conflicted fitness function using estimates of the local conflict region around a conflicted trajectory is also presented. Preliminary performance characteristics of the implemented algorithm are provided
UAS Concept of Operations and Vehicle Technologies Demonstration
In 2017 and 2018, under National Aeronautics and Space Administration (NASA) sponsorship, the New York Unmanned Aircraft Systems (UAS) Test Site and Northeast UAS Airspace Integration Research (NUAIR) Alliance conducted a year-long research project that culminated in a UAS technology flight demonstration. The research project included the creation of a concept of operations, and development and demonstration of UAS technologies. The concept of operations was focused on an unmanned aircraft transiting from cruise through Class E airspace into a high-density urban terminal environment. The terminal environment in which the test was conducted was Griffiss International Airport, under Syracuse Air Traffic Control (ATC) approach control and Griffiss control tower. Employing an Aurora Centaur optionally piloted aircraft (OPA), this project explored six scenarios aimed at advancing UAS integration into the National Airspace System (NAS) under both nominal and off-nominal conditions. Off-nominal conditions were defined to include complete loss of the communications link between the remote pilots control station on the ground and the aircraft. The off-nominal scenarios that were investigated included lost-link conditions with and without link recovery, an automated ATC initiated go-around, autonomous rerouting around a dynamic airspace obstruction (in this case simulated weather), and autonomous taxi operations to clear the runway

Investigating Humor Within a Context of Death and Tragedy: The Narratives of Contrasting Realities
Crime scene investigators (CSIs) are subjected to many complexities of working in a context of death, trauma and tragedy. They experience this context in a more intimate manner than any other member of the criminal justice community. Within these challenging work settings in which human lives have ended, humor can emerge as crime scene investigators attend to their tasks. The research question this study addressed is “How is humor used to negotiate work experiences and make meaning from working in a context that includes death, trauma and tragedy?” CSIs were interviewed and provided narratives from their lived experiences regarding humor during their challenging work. Humans often use storytelling to frame and construct meaning of their lived experiences. For the CSI, the telling and retelling of stories of laughter and stories of tears has several individual and organizational outcomes, including group socialization, negotiating the stresses of the work and meaning making
