Incremental solution of LTMGA transfers transcribed with an advanced shaping approach

In the last decade the global optimisation of low-thrust multi-gravity assist transfers (LTMGA) has been tackled with different approaches. Some authors proposed to generate a first guess solution by building a multi-gravity assist transfer with impulsive manoeuvres and then using a direct or an indirect method to transcribe the multi-impulse arcs into low-thrust arcs. Other authors, notably Petropoulos et al. (2002), De Pascale et al. (2006), Wall et al. (2008) and Schütze et al. (2009), proposed the use of several forms of trajectory shaping to model low-thrust arcs. The disadvantage in all these studies is that the swingbys are powered and therefore suggest the use of high thrust propulsion along with the low thrust propulsion on board the spacecraft. The problem generally resides in the lack of flexibility of the low thrust trajectory models to satisfy a variety of boundary conditions. In this paper, a spherical shaping model is used whereby all encountered types of boundary constraints are satisfied analytically. Furthermore, a special incremental pruning of the search space is performed before employing a global optimiser. The process is conceptually equivalent to the approach proposed by Becerra et al. for the search space pruning of multi-gravity assist trajectories and exploits the decoupling of pairs of transfer arcs. Such decoupling removes the dependency of one arc from all those that are two or more before, and allows for pruning the search space in polynomial time. Numerical examples are presented for LTMGA transfers from Earth to asteroid Apollo and Earth to Jupiter

Software application using .NET platform for a company that produce and sells wine

In the first part of the paper is presented a short review of the main concepts regarding .NET platform and VSTO. In the second part of the paper we present application of the software that will attach a code, to a Word document.The software application attach Office code to a document, for a company that produces and sells wine, using the .NET platform and this application transform a static document, in a dynamic document. The developed application is important in wine sales, because by querying the database application we can obtain different information that can bring good profits and optimize the costs of a company that produces and sells wine

A Model for an Intelligent Support Decision System in Aquaculture

The paper purpose an intelligent software system agents–based to support decision in aquculture and the approach of fish diagnosis with informatics methods, techniques and solutions. A major purpose is to develop new methods and techniques for quick fish diagnosis, treatment and prophyilaxis at infectious and parasite-based known disorders, that may occur at fishes raised in high density in intensive raising systems. But, the goal of this paper is to presents a model of an intelligent agents-based diagnosis method will be developed for a support decision system.support decision system, diagnosis, multi-agent system, fish diseases

Modeling the Evolution of Companies using Intelligent Software Agents Architecture

The paper presents the concept of multi agent system that models the evolution of a company. The opportunity of such an approach and the limits of mathematical modeling are presented. The main players on the market are modeled as cognitive, adaptive, heterogeneous agents and evolve in a dynamic environment. The purpose is to use the model of operational agent that has these characteristics. This model is based on using an ATN (Augmented Transition Network) to adapt the behavior of its agent to the changes it detects in its environment. Each agent has an inference mechanism for the first order reasoning. The agents communicate between them through messages and will be implemented in a non synchronized object environment.multiagent system, economic model, discret events

The Party, the Great Redeemer: an existential-political commentary on Orwell’s 1984

Given its multifaceted relevance, Orwell’s 1984 has enjoyed a plethora of theoretical and artistic interpretations. However, I have not come across any such interpretation concerned with the ontological temporality of the novel, i.e. not its narrative development, but its use of temporality as the basic horizon of self-awareness, both existentially and politically. Considering this to be a key feature of both Orwell’s novel and totalitarian systems in general, I have taken upon myself the task of loosely exploring such an approach. As it will become apparent, I rely strongly on Heidegger’s account of existential and historical time (especially his concept of Being—towards-death). Basically, I will try to provide an existential account of totalitarianism as the resulting systemic product of the flight from the Beingtowards-death in particular, respectively an attempt at subduing temporality, in general. In addition, I will make, when deemed necessary, several contextual references to other thinkers such as Foucault, Nietzsche, Freud, Plato and Gadamer

STRATEGIC CONTROLLING IN ROMANIA-SUPPORT OF MANAGERIAL DECISIONS

This paper introduces theoretical matters concerning the strategic controlling procedure as well as economical practice elements up to corporate group branch. Especially by its concurrence to strategically scheduling and its add to strategically feed forward and feedback process, the strategically controlling supports the composition of managerial decisions on strategic level.controlling, decision, management.

Technomorphic Dystopias: Westworld. A Hermeneutic Case-Study on the Relation between Ideology, Ontology and Art

Supposedly, every ideology comes along with its own epistemological and artistic proclivities. The stronger version of this claim, today quite frequently met, would be that ideologies dictate their own version of truth. If that were so, ideologies would constitute ideationally self-sufficient monads, with no possibilities of interaction. As this is quite evidently not the case, it means that there is a pre-and transideological space that enables such interaction. I would hold that this is ontology, i.e. the general understanding of Being, that subjacently encompasses everything having to do with ideology, epistemology, and art. In other words, changes in ontology induce changes in the latter three that interreflect and eventually feed back into ontology. Given its dialectical closeness to all four, the hermeneutic object chosen in this article for the illustration of this argument is Jonathan Nolan and Lisa Joy’s sci-fi dystopianutopia Westworld. On the theoretical side, the paper drew heavily on the works of Mannheim, Heidegger, Gadamer, and Marcuse
