CONT

The active debris removal(ADR) concept has continuously evolved for the debris removal from the LEO [low Earth orbit] region. One of the evolving ADR methods is space robotics which has continuously matured over a couple of decades. In space robotics, the satellite system consists of a robotic arm mounted over it which can be called a debris chaser satellite. The main function of the debris chaser satellite is to chase, capture and de-orbit the space junk to a very low earth orbit.

Au cours d'une mission de retrait actif d'un débris spatial en orbite autour de la Terre, un engin spatial chasseur ou un satellite chasseur doit aller à la rencontre du débris de grande taille, par exemple un satellite cible, avec l'objectif de modifier son orbite soit pour une réentrée dans l'atmosphère ou un placement dans une orbite cimetière de ce dernier. Différentes techniques de capture de débris de grandes tailles ont été proposées et peuvent être classées en trois classes : une première classe dans laquelle un lien rigide entre le débris et l'engin chasseur est établi par exemple au travers de bras robotiques ou de mécanismes de saisie ou de prise; une deuxième classe dans laquelle un lien souple entre le débris et l'engin chasseur est mis en œuvre par exemple en utilisant des filets ou des harpons; une troisième classe, formée par des systèmes de capture sans contact de l'engin chasseur avec le débris et utilisant par exemple une projection de mousse ou un guidage par faisceau d'ions.

CONT

Heat emitters in central heating systems may be classified in two broad groups: primarily convective and primarily radiant.

CONT

Radiators, convectors, and baseboard and finned tube units are types of heat-distributing devices commonly used in steam and low temperature water heating systems. They supply heat through a combination of radiation and convection, and their function is to maintain the desired air temperature in the space. In general, these types of heat-distributing units should be placed at the points of greatest heat loss of the space to offset or counteract these losses. For example, such units are commonly located under windows, along exposed walls, and at door openings.

The tendency of a material, such as a metal, to lose strength after acoustic stress.

The X-15 provided the first opportunity to study the effects of acoustical fatigue over a wide range of Mach and dynamic pressures. In these first inflight measurements, "noise" related stresses were found to be a function of g-force, not Mach number.

This knowledge has allowed for more optimum structural design of missiles and space capsules that experience high velocities.

  • Remote Sensing
DEF

A projection technique that reduces data dimensionality, and an advanced neural network that utilizes fuzzy-set mathematics.

CONT

The intent for multispectral and hyperspectral image data analysis is to rapidly and inexpensively associate a ground cover label to each pixel in the image. Given the multivariate nature of such data, the process of data analysis is one of dividing up the N-dimensional feature space into M exhaustive but non-overlapping regions where M is the number of classes of materials existing in the scene. The process involves defining the M classes of interest in a quantitative fashion, such that each pixel in the scene, which exists as a discrete location in the N-dimensional space, can be uniquely associated with one of the M classes. Frequently, this is done by using a small number of samples in the scene, called design samples or training samples, to define an N-dimensional probability density function for each of the M classes.

The Leonardo Multipurpose Logistics Module, which was built by the Italian Space Agency(ASI), is the first of three such pressurized modules that will serve as the International Space Station's "moving vans, "carrying laboratory racks filled with equipment, experiments and supplies to and from the Station aboard the Space Shuttle. The unpiloted, reusable logistics modules function as both a cargo carrier and a Space Station module when they are flown. Mounted in the Space Shuttle's cargo bay for launch and landing, they are berthed to the Station using the shuttle's robotic arm after the shuttle has docked. While berthed to the Station, racks of equipment are unloaded from the module and then old racks and equipment may be reloaded to be taken back to Earth. The logistics module is then detached from the Station and positioned back into the Shuttle's cargo bay for the trip home. When in the cargo bay, the cargo module is independent of the Shuttle cabin, and there is no passageway for Shuttle crewmembers to travel from the Shuttle cabin to the module. In order to function as an attached Station module as well as a cargo transport, the logistics modules also include components that provide some life support, fire detection and suppression, electrical distribution and computer functions. Eventually, the modules also will carry refrigerator freezers for transporting experiment samples and food to and from the station.

CONT

When the International Space Station (ISS) was redesigned again in 1993, NASA & the Italian Space Agency decided to expand the original Mini-Pressurized Logistics Module design. The new MultiPurpose Logistics Module is twice as long and an carry up to 9000kg of cargo to ISS. ... The module carries up to sixteen refrigerator-sized (203 x 105cm) payload racks, five of which may contain refrigerators/freezers. Other so-called "EXPRESS Racks" can be outfitted with lockers for small experiments. Additional cargo can be carried in center aisle stowage containers.

Subject field(s)
  • Radar, Radio Guidance and Goniometry
DEF

The volume in space that is irradiated by a given radar; for a continuous-ware radar it is equivalent to the antenna radiation pattern; for a pulse radar it is a function of the cross-section area of the beam of the antenna and the pulse length of the transmitted pulse.

Subject field(s)
  • Artificial Intelligence
CONT

In IDEBUGGY, to limit and optimize the use of time, a heuristically guided controller chooses among the different tasks that are possible at any point. Then it activates small independent modules to perform specific actions. In this way, the control is never committed to any single function for a long period of time. At a high level, IDEBUGGY must deal with two alternating tasks : generating problems and managing the space of hypotheses.

Since(R, T) is a metric topological space, it is also a Hausdorff space, and function [phi-(i]), being a diffeomorphism, is also a homeomorphism from an open set of R to an open set of [the energy hypersurface].

Difféomorphisme d'un ouvert U d'un R-espace vectoriel normé E dans un ouvert V d'un R-espace vectoriel normé F : Application de U dans V qui est bijective, continûment différentiable et dont la bijection réciproque est aussi continûment différentiable.

English

Subject field(s)
  • Biochemistry
DEF

The differential expression of gene action at the chromosome level brought about via mechanisms of repression and derepression.

OBS

Specific products of the cell determine which genes of the genome will function. The cell, in turn, is modified by the action of these genes with the result that particular genes are then derepressed in succession(operon). In higher organisms, differential gene action is a fundamental component of the processes of differentiation and development and follows a definite pattern in time and space.

DEF

A function on the spectrum of an operator on a Hilbert space whose values are projection operators there; spectral theorems concerning linear operators often give an integral representation of the operator in terms of these projection operators and measures.
