Résumé :
This paper discusses the application of an inherently three-dimensional graphical representation tool, isosurfaces, as a means to interactively explore and visualize the attractors of a nonlinear dynamical system with a fifteen-dimensional parameter space. A program has been written which allows the scientist to interactively select and visualize three-dimensional sub-spaces of the fifteen-dimensional parameter space. The dynamical system used to illustrate these concepts is a discrete-time, nonlinear, three-nation Richardson model with economic constraints. This dynamical system, which models the shifting alliances of nations in an arms race, maps an initial point in the unit cube to another point in the unit cube after multiple iterations of the model functions. Using an isosurface function on the resulting volumetric data set, surfaces indicating the changing alliances of nations are generated and rendered.

Résumé :
This article focuses on the exploration of our solar system that has, in a very literal sense, extended the reach of mankind. Developing the technology of that exploration has extended immensely the capacity of engineering. The new technologies and key capabilities being developed include intelligent robotics, advanced propulsion systems, power generation, avionics, telecommunications, and instruments. Technology for sample acquisition and return encompasses power and propulsion, robust landing, sensors, handling and packaging systems, ascent vehicles, and autonomous rendezvous and capture systems. Measures are needed to ensure that the samples are not contaminated during collection or the return to Earth, and that samples cause no harm to the Earth's environment. Some of the future solar system missions will experience extreme environments. The extreme cold and intense radiation around Europa, or the searing heat and crushing pressure of Venus, would limit the lifetime of systems built with present technology to just minutes. Improved pressure vessels, thermal control, environmentally tolerant electronics, and low-power systems are needed to prolong the lives of vehicles and instruments for these missions.

Résumé :
Electromagnetic (EM) exploration systems fall into three distinct classes, (1) frequency domain, (2) impulse response, and (3) step response, and have overall frequency responses that approximate [Formula: see text], [Formula: see text], and [Formula: see text]. To examine further these three classes, the transfer function of a frequency‐domain system, and the step and impulse response functions of ideal time‐domain EM systems (TEM), are derived in terms of a single set of target‐specific parameters. The inductive time constants of practical exploration targets extend over three orders of magnitude, imposing severe constraints on practical exploration systems. Field data demonstrate that the impulse TEM response from a conductive half‐space may show a 100‐fold spatial variability at early times (≲1 ms) and then will decrease to a two‐fold variability at late times ( ⩾4 ms). This differential variability influences the ability of an EM system to detect an exploration target. For a half‐space where the impulse response varies as [Formula: see text], an inductive target of time constant τ exhibits the greatest contrast to the half‐space at a delay time of kτ for an impulse‐response system, and at [Formula: see text] for a step‐response system.

Résumé :
For over past years, interest of leading space agencies (NASA, JAXA, ESA, RSA, etc.) in SHS experiments under microgravity conditions has been increasingly growing. The first SHS experiments during a parabolic flight in Russia and aboard the MIR Space station gave promising results. Similar studies are now<br />being carried out in various countries. The obtained data and assimilated experience have shown that SHS reactions can be used for (a) synthesis of high-porosity materials and regulation of structure formation in combustion products, (b) preparation of skeleton structures by combustion of particles suspended in vacuum, (c) generation of thermal energy, (d) generation of incandescent radiation, and (e) for in-space fabrication and in-situ repair works (welding, joining, cutting, coating, near-net-shape production, etc.). However, the results of the above studies (strongly scattered in the literature) still seem insufficient for elucidating the mechanism of combustion in. Indeed, the experiments were carried out by different researchers for a dozen<br />of systems and for strongly different duration of microgravity (drop towers, parabolic flight of a plane, parabolic flight of a spacecraft, in space stations). No correlation has been made with the available data of SHS studies (oriented largely on practical implementation) in conditions of artificial gravity. In experiments, the combustion wave has enough time to spread over the sample while the structure formation, may not have. This implies that the process of wave propagation should always be identical, <br />irrespective of the type of experimental technique and place of experiment. SHS experiments in space are attractive because (a) of low energy requirements, (b) processing cycle is short, (c) of process simplicity, (d) of versatility (wide range of suitable materials, and (e) the use of in-situ resources possible. To date, SHS experiments has already been performed aboard the International Space Station (ISS). Space technology has been developed for frontier exploration not only around the Earth orbit environment but also to the Moon, Mars, etc.

Résumé :
Due to the ever-growing requirements in high performance data computation, multiprocessor systems have been proposed to solve the bottlenecks in uniprocessor systems. Developing efficient multiprocessor systems requires effective exploration of design choices like application scheduling, mapping, and architecture design. Also, fault tolerance in multiprocessors needs to be addressed. With the advent of nanometer-process technology for chip manufacturing, realization of multiprocessors on SoC (MpSoC) is an active field of research. Developing efficient low power, fault-tolerant task scheduling, and mapping techniques for MpSoCs require optimized algorithms that consider the various scenarios inherent in multiprocessor environments. Therefore there exists a need to develop a simulation framework to explore and evaluate new algorithms on multiprocessor systems. This work proposes a modular framework for the exploration and evaluation of various design algorithms for MpSoC system. This work also proposes new multiprocessor task scheduling and mapping algorithms for MpSoCs. These algorithms are evaluated using the developed simulation framework. The paper also proposes a dynamic fault-tolerant (FT) scheduling and mapping algorithm for robust application processing. The proposed algorithms consider optimizing the power as one of the design constraints. The framework for a heterogeneous multiprocessor simulation was developed using SystemC/C++ language. Various design variations were implemented and evaluated using standard task graphs. Performance evaluation metrics are evaluated and discussed for various design scenarios.

Résumé :
This paper offers a Human Factors and Ergonomic & Sociotechnical Systems (HFE & STS) methodology to assist in the exploration and description of COVID-19 lockdown impacts on public spaces in Queensland, Australia. The approach utilises an existing - before COVID - systems model of an archetype public space to identify activities that were restricted in public space, and how such restrictions affect system performance. First an overview of the HFE & STS system modelling approach, Cognitive Work Analysis, is provided and we present the systems model of an archetype public space. Next, the range of lockdown restrictions on public space activity are identified in the model and the system's implications on community and individual wellbeing are explored. In conclusion, the necessity for new activities and functions of public space, post COVID-19, are reflected upon and considered from a systems standpoint.

Résumé :
It has been more than half a century since humans first ventured into space. While competing in being the first to land on the Moon, they learned to utilize space for human needs on Earth (e.g., telecommunications, navigation systems). Many space technologies were later applied to basic needs on Earth. Space research and development led to the “transfer of technology” in non-space sectors and became better known as “spin-offs.” They have improved global modern life in many ways. This paper discusses the cost-benefit of space technology spin-offs, as well as the relationships between various space agencies, spin-offs, and commercial enterprises. Other benefits that have come out of space exploration such as psychological, political and environmental effects are also reviewed, as well as the potential future benefits of going to space. Technologies developed for harsh environments on Earth and for those in space benefit all and collaborating both ways is the future.

Résumé :
Active Inference (AIF) is a framework that can be used both to describe information processing in naturally intelligent systems, such as the human brain, and to design synthetic intelligent systems (agents). In this paper we show that Expected Free Energy (EFE) minimisation, a core feature of the framework, does not lead to purposeful explorative behaviour in linear Gaussian dynamical systems. We provide a simple proof that, due to the specific construction used for the EFE, the terms responsible for the exploratory (epistemic) drive become constant in the case of linear Gaussian systems. This renders AIF equivalent to KL control. From a theoretical point of view this is an interesting result since it is generally assumed that EFE minimisation will always introduce an exploratory drive in AIF agents. While the full EFE objective does not lead to exploration in linear Gaussian dynamical systems, the principles of its construction can still be used to design objectives that include an epistemic drive. We provide an in-depth analysis of the mechanics behind the epistemic drive of AIF agents and show how to design objectives for linear Gaussian dynamical systems that do include an epistemic drive. Concretely, we show that focusing solely on epistemics and dispensing with goal-directed terms leads to a form of maximum entropy exploration that is heavily dependent on the type of control signals driving the system. Additive controls do not permit such exploration. From a practical point of view this is an important result since linear Gaussian dynamical systems with additive controls are an extensively used model class, encompassing for instance Linear Quadratic Gaussian controllers. On the other hand, linear Gaussian dynamical systems driven by multiplicative controls such as switching transition matrices do permit an exploratory drive.

The space exploration vision announced by President Bush on January 14, 2004 requires a new way of thinking about human-machine systems. A progressive and sustained exploration of the Moon, Mars, and other destinations of discovery will depend on system design that supports and extends the capabilities of our astronauts through advanced automation, distributed mission support, and effective human-robot teaming. We provide an overview of the developmental program of exploration, and the critical Human-Systems Integration (HSI) challenges associated with each of seven operational domains: mission control operations; self-sufficient spacecraft operations; extra-vehicular activity / teleoperations; training and on-board decision support; launch-site operations; HSI engineering support; and behavioral health and performance.

Résumé :
Prebiotic chemistry often involves the study of complex systems of chemical reactions that form large networks with a large number of diverse species. Such complex systems may have given rise to emergent phenomena that ultimately led to the origin of life on Earth. The environmental conditions and processes involved in this emergence may not be fully recapitulable, making it difficult for experimentalists to study prebiotic systems in laboratory simulations. Computational chemistry offers efficient ways to study such chemical systems and identify the ones most likely to display complex properties associated with life. Here, we review tools and techniques for modelling prebiotic chemical reaction networks and outline possible ways to identify self-replicating features that are central to many origin-of-life models.

Résumé :
In this paper, micropropulsion systems are analyzed in conjunction with the various mission requirements of China’s deep space exploration. As a great challenge facing the world, deep space exploration can be enabled only in a few countries with a success rate of around 50%. With the advancement of spacecraft and scientific instruments, it is now feasible to build small and low-cost spacecraft for a variety of deep space missions. As spacecraft become smaller, there is a need for proper micropropulsion systems. Examples of propulsion system selections for deep space exploration are discussed with a focus on products developed by Beijing Institute of Control Engineering (BICE). The requirements for propulsion systems are different in lunar/interplanetary exploration and gravitational wave detection. Chemical propulsion is selected for fast orbit transfer and electric propulsion for increasing scientific payloads. Cold gas propulsion and microelectric propulsion are good choices for space-based gravitational wave detection due to the capability of variable thrust output at the micro-Newton level. The paper also introduces the sub-1-U micropropulsion modules developed by BICE with satisfactory performance in flight tests, which are promising propulsion systems for small deep space platforms. A small probe with an electric sail propulsion system has been proposed for the future solar system boundary exploration of China. The electric sail serves as not only a propellant-free thruster but also a detector probing the properties of the space medium.

Human space expeditions have, from the beginning, involved great risk and complexity. Space flights, accordingly, have utilized substantial quantities of highly skilled labor. The rapid creation and evolution of increasingly powerful information technologies promise a new human-automation systems balance of work. This balance holds the potential of greatly increased crewed and robotic space exploration capability, along with dramatically reduced costs. Since further development of sophisticated information technology systems must, from the outset, consider both the human and the machine as “components” of an integrated system, research supporting the development and optimal utilization of such systems will necessarily incorporate significant human factors components. This paper examines the impact of information technologies on lunar and planetary missions; exemplar inherent human factors aspects, such as display and control in virtual environment/teleoperated systems, are considered.

Résumé :
The exploration of the Moon and other planets of the Solar system involves a widespread use of robotic systems of various types and purposes. However, currently there is no generally accepted frame of reference for the effective application of different robotic systems for performing space exploration tasks. Based on the approach to the selection of priority robotic systems proposed by the authors, possible areas of their advanced application to support the implementation of the Russian lunar program are considered in this paper. Multi-criteria classification of space-based robotic systems, features of remote control of robots, and directions of work on the development of Russian robotic systems for the lunar program are also examined. The questions of necessity, possibility and validity of flight operations using space-based robotic systems are explored. The tasks of robots in the exploration of the Moon, which are divided into four phases: infrastructure, provision, operation and research, are considered. Key technologies of space robotics (electronics, mechanics, software, control), as well as related technologies at their intersection are presented. Three main areas of Roscosmos’ work on the development of technological, anthropomorphic and freight robots are presented. Conclusions on the implementation of plans for the exploration and use of the Moon are drawn.

Résumé :
One of the primary goals of human spaceflight has been putting human cognition on other worlds. This is at the heart of the premise of what we call space exploration. But Earth-controlled telerobotic facilities can now bring human senses to other worlds and, in that respect, the historical premise of exploration, of boots on the ground, no longer clearly applies. We have ways of achieving remote presence that we never used to have. But the distances over which this must be achieved, by humans based on the Earth, is such that the speed of light seriously handicaps their awareness and cognition. The highest quality telepresence can be achieved not only by having people on site, but also by having people close, and it is that requirement that truly mandates human spaceflight. In terms of cost, safety, and survival, getting people close is easier than getting people all the way there. It is suggested here that to the extent that space exploration is best accomplished by achieving a sense of real human off-Earth presence, that presence can be best achieved by optimally combining human spaceflight to mitigate latency, with telerobotics, to keep those humans secure. This is culturally a new perspective on exploration.

Résumé :
As modern embedded systems are becoming more and more ubiquitous and interconnected, they attract a world-wide attention of attackers and the security aspect is more important than ever during the design of those systems. Moreover, given the ever-increasing complexity of the applications that run on these systems, it becomes increasingly difficult to meet all security criteria. While extra-functional design objectives such as performance and power/energy consumption are typically taken into account already during the very early stages of embedded systems design, system security is still mostly considered as an afterthought. That is, security is usually not regarded in the process of (early) design-space exploration of embedded systems, which is the critical process of multi-objective optimization that aims at optimizing the extra-functional behavior of a design. This position paper argues for the development of techniques for quantifying the ’degree of secureness’ of embedded system design instances such that these can be incorporated in a multi-objective optimization process. Such technology would allow for the optimization of security aspects of embedded systems during the earliest design phases as well as for studying the trade-offs between security and the other design objectives such as performance, power consumption and cost.

Résumé :
AbstractDesign of software in the automotive domain often involves simulation to allow early software parametrization. Modeling complex systems or components impacted by the software in an analytical way can be time-consuming, require domain knowledge and executing the analytical models can result in high computational effort. In specific applications, these challenges can be overcome by applying machine learning based simulation. This contribution presents results of a case study in which powertrain components are modeled data-driven with artificial neural networks to support design space exploration
