Plans are currently converging towards a return of humans to the lunar surface within the upcoming decade. This return of humans to the lunar surface will utilise the Gateway as a reusable command and service module in cis-lunar space. Here, we are performing a fresh analysis of human lunar return architectures, starting with the identification of a complete set of plausible scenarios for crewed logistics from the Gateway to the lunar surface and back. In a next step, this set is evaluated with the intension in mind to identify scenarios in the 2020's. Three prominent candidate scenarios, distinct by the basic staging approach, have been identified and analysed in detail with respect to configuration design, system trades, operational aspects and the benefit each scenario is generating. With these key points in mind, the three scenarios are compared in order to identify the most suitable approach. Furthermore, a step-wise approach towards an increasingly sustainable human lunar surface campaigns is analysed and discussed. This approach introduces an increasing number of reusable elements by increasing the technological progression. It is found that a three-stage lander architecture promises a high mass efficiency and thus this approach is investigated in more detail of system engineering and requirements.

The meeting of two spacecraft in orbit around a planet or moon involves a delicate dance that must carefully the balance the gravitational, Coriolis, and centrifugal forces acting on the spacecraft. The intricacy of the relative motion between the two spacecraft caused problems for the Gemini missions in the mid-1960s. Although now mastered, the problem of how to bring two orbiting objects together continues to be misrepresented in popular movies and books. In this article, I will consider the case when the two spacecraft are in close proximity (compared with the radii of their orbits), and examine the counter-intuitive trajectories that are needed to bring them together. I will examine how a stranded astronaut might use an impulsive force to return to her ship in Earth orbit, how and when line-of-sight targeting may be used for a rendezvous, and how the Apollo 11 lunar module executed a Terminal Phase Initiation maneuver to rendezvous with the command/service module as they both circled the Moon., Comment: 29 pages, 15 figures.

WHEN ASTRONAUTS FIRST landed on the moon a half century ago, they went there in a single shot: A Saturn V rocket launched the Apollo command and service module and the lunar lander, which entered into a low orbit around the moon. The lander then detached and descended to the surface. After 22 hours in the moondust, the Apollo 11 astronauts climbed into the lander's ascent stage and returned to the command module for the trip back to Earth. • NASA's current plan for sending astronauts back to the moon, which may happen as soon as 2024, goes a little differently. A series of commercial rockets will first launch the components of a small space station, which will self-assemble in high lunar orbit. Then another rocket will send up an unoccupied lunar lander. Finally, a giant Space Launch System (SLS) rocket will launch an Orion spacecraft (which looks a lot like an Apollo command module), with astronauts inside. Orion will dock with the space station, and some of the astronauts will transfer to the waiting lander. Finally, the astronauts will descend to the lunar surface. After their sortie on the moon, they'll return to the orbital station, where the crew will board Orion for the trip home. • That lunar orbital space station is envisioned as a collection of modules, including habitats, an air lock, and a power and propulsion unit. NASA calls it the Gateway.

A novel non-contact satellite for drag-free and attitude control is proposed in this paper. The non-contact satellite is separated into a payload module and a service module by non-contact Lorentz actuators. Instead of thrusters, the non-contact Lorentz actuators are used to exerted precise forces and torques, enabling drag-free and attitude control of the payload module, while the service module is designed to track the payload module to avoid collision. On the basis of this new design, the dynamics of drag-free and attitude control can be precisely modeled. Accordingly, a hierarchical control algorithm, consisting of an EKF-based estimation and rejection of environmental acceleration of payload module, attitude control of payload module, minimum norm allocation of non-contact Lorentz actuators, as well as collaborative control of service module, is systematically designed. A numerical simulation is then conducted to demonstrate the validity and effectiveness of the proposed design.

In the big data era, a variety of new data can be collected from various sources and analyzed through different techniques to support the decision-making regarding product customization. Based on a thorough investigation of relevant data, this paper presents a new customization framework that is greatly driven by data. The framework includes three interrelated components: data module, design module, and service module. It is intended to promote smart customization in terms of product designing, manufacturing, pricing, marketing, and service. A case study of product customization in the footwear industry is presented to instantiate the implementation of the proposed framework.

The development of customized service is an important way to transform and upgrade China’s mining industry. However, in practice, there remain problems, such as the slow market response speed of service providers and the contradiction between the large-scale development of service providers and the personalized service needs of service demanders. This paper uses the theory and method of service modular design to solve these problems and explores the process-based service modular design method. Service modular design depends largely on the determination of the relationship between service activities and the reasonable division of modules. However, previous research has rarely made use of modular design methods and modeling tools in the mining service context. At the same time, evaluations of the relationship between service activities relying on knowledge and those relying on experience have been inconclusive. Therefore, this paper proposes a service modularization design method based on the fuzzy relation analysis of a design structure matrix (DSM) that solves the optimal module partition scheme. Triangular fuzzy number and fuzzy evidence theory are used to evaluate and fuse the multidimensional and heterogeneous relationship between service activities, and the quantitative processing of the comprehensive relationship between service activities is carried out. On this basis, the service module structure is divided, followed by the construction of the mathematical programming model with the maximum sum of the average cohesion degree in the module and the average coupling degree between modules as the driving goal. The genetic algorithm is used to solve the problem, and the optimal module division result is obtained. Finally, taking the service modular design of SHD coal production enterprises in China as an example, the feasibility of the proposed method is verified.

International audience; Euclid, an ESA mission designed to characterise dark energy and dark matter, passed its Mission Critical Design Review in November 2018. It was demonstrated that the project is ready to start integration and test of the main systems, and that it has the ability to fulfil its top-level mission requirements. In addition, based on the performances at M-CDR, the scientific community has verified that the science requirements can be achieved for the Weak Lensing and Galaxy Clustering dark energy probes, namely a dark energy Figure of Merit of 400 and a 2% accuracy in the growth factor exponent gamma. We present the status of the main elements of the Euclid mission in the light of the demanding high optical performance which is the essential design driver is the to meet the scientific requirements. We include the space segment comprising of a service module and payload module hosting the telescope and its two scientific instruments, and the ground segment, which encompasses the operational and science ground segment. The elements for the scientific success of the mission for a timely release of the data are shortly presented: the processing and calibration of the data, and the design of the sky survey. Euclid is presently on schedule for a launch in September 2022.

The Flexible Lunar Architecture for Exploration (FLARE) is a concept to deliver four crew to the lunar surface for a minimum of seven days and then return them safely to Earth. FLARE can be implemented whenever the component vehicles are operational. FLARE was developed as an alternative to NASA's Human Landing System (HLS) reference architecture from the Design Analysis Cycle (DAC) #2 created in 2019. The DAC2 guidelines required utilization of the Gateway vehicle in a Near- Rectilinear Halo Orbit (NRHO). Instead, FLARE chooses a Low Lunar Frozen Polar Orbit (LLFPO) for lunar rendezvous of components, and an optional Gateway vehicle. The LLFPO provides a stable orbit that overflies the south pole every 2 h, ensuring easy access to the lunar surface for surface aborts with a much lower propellant requirement than NRHO. The minimum FLARE concept uses one Space Launch System (SLS) launch, one Orion, one European Service Module (ESM), and one human lander (launched on commercial vehicle(s)). FLARE adds the SpaceTug, based upon the mature and successful ULA “Common” Centaur Upper Stage vehicle, with modifications to create an Earth-Moon transfer vehicle. In the FLARE baseline mission, the SpaceTug provides propulsion needed to return the Orion + ESM from LLFPO to Earth. The SpaceTug also provides propulsion to deliver the separate human lander components – the Descent Element (DE) and the Ascent Element (AE) - from Low Earth Orbit (LEO) to LLFPO. The SLS Block 1 then launches the Orion + ESM and completes a rendezvous with the mated DE + AE components in LLFPO. FLARE offers optional phases beyond the baseline mission. The SpaceTug can deliver components of the planned Gateway, including the Power and Propulsion Element (PPE) and the Habitable and Logistics Outpost (HALO), to LLFPO. FLARE provides an option to deliver precursor equipment to the lunar surface to enhance and extend the human mission. With these components, including an inflatable habitation module and airlock, individual crew mobility vehicle(s), an In-Situ Resource Utilization (ISRU) demonstration, and science and technology experiments, the crew can explore and conduct science on the lunar surface for up to 14 days., Highlights • Deliver 4 crew to the lunar surface for 7–14 days and return them safely to Earth. • Minimum mission requires 7 CLVs & 1 SLS-B1 launch using Orion + ESM and a human lander. • Minimum mission requires 5 SpaceTugs to transfer mass between Earth and Moon orbits. • Gateway elements (PPE, HALO) are not required, but not precluded, if in low lunar orbit. • Optional cargo mission to the lunar surface adds hab, mobility devices, & experiments.

In this paper we present a fast method based on successive convexification for generating fuel-optimized spacecraft rendezvous trajectories in the presence of mixed-integer constraints. A recently developed paradigm of state-triggered constraints allows to efficiently embed a subset of discrete decision constraints into the continuous optimization framework of successive convexification. As a result, we are able to solve difficult trajectory optimization problems at interactive speeds, as opposed to a mixed-integer programming approach that would require significantly more solution time and computing power. Our method is applied to the real problem of transposition and docking of the Apollo command and service module with the lunar module. We demonstrate that, within seconds, we are able to obtain trajectories that are up to 90 percent more fuel efficient (saving up to 45 kg of fuel) than non-optimization based Apollo-era design targets. Our trajectories take explicit account of minimum thrust pulse width and plume impingement constraints. Both of these constraints are naturally mixed-integer, but we handle them as state-triggered constraints. In its current state, our algorithm will serve as a useful off-line design tool for rapid trajectory trade studies., Comment: 23 pages, 10 figures, submitted to AIAA SciTech 2020

We have described an express technique for processing the results of experiments with a DAKON-M convection sensor on board the Service Module of the International Space Station (ISS) in 2011. The technique uses a certain rule to compare the sensor measurements with the calculated data on the quasistatic component of microacceleration at the point of installation. The sensor experiments have been conducted during shuttle docking and undocking, when low-frequency microaccelerations on the ISS were significant. The microaccelerations have been calculated using measurement data of the MAMS low-frequency accelerometer installed in the Lab module and the telemetry data on the ISS rotational motion. This has made it possible to convert the MAMS measurement data to the DAKON-M convection sensor installation point. A comparison of sensor readings with calculated microaccelerations has revealed fairly good agreement between them.

The paper considers development of the Information Control System (ICS) of the Russian Segment of the International Space Station (ISS). The main ICS modules for carrying out scientific experiments comprise the Service Module, the Multipurpose Laboratory Module and the Science Power Module. At present specialists of Energia RSC are working to create high-tech conditions for scientific experiments on the new ISS modules, modernize the existing ones and combine them into a single onboard ISS information control complex. The information control system (ICS) is intended for automatic and manual control of space experiments. The effectiveness of modernization was confirmed by the results obtained during space experiments on the basis of the Information Control System. The ICS modernization started in 2012. At that time the ICS consisted of 4 onboard computers. The main task of ICS modernization was to introduce new computers and software-hardware systems. The software was supposed to have a flexible architecture and provide resources for all future onboard payloads. At the first stage one onboard computer was replaced. The main purpose of that stage was to test the new ISS hardware and software. The rest of the ICS computers will be replaced at the second stage, the Multipurpose Laboratory Module and the Science Power Module will also be equipped. The reliability of the system hardware is improved using functional backup. In 2014 2 cameras were installed on the ISS together with UrtheCast company (Canada).One of the cameras is a middle resolution camera; the other one is a high resolution camera. Today ground preparation of an experiment with Icarus scientific equipment is being carried out, jointly with the German Center of Aviation, DLR, and the SpaceTech company (Germany). The experience of the first stage of modernization suggests that the modernized ISS RS ICS will become an up-to-date system allowing the realization of most ambitious space experiments in automatic mode.

This paper discusses the application of computer-assisted design systems to development of low thrust spacecraft intended to take an exploratory flight to potentially hazardous asteroids. The design model of the low thrust spacecraft that is created with computer-aided design systems is described. The mathematical motion model within the heliocentric system of coordinates for such type of spacecraft is considered and used for a motion simulation session. The simulation of flight to the potentially hazardous asteroid is performed with the aid of special complex software that is developed for the purpose of the work. The results of the paper consist of a detailed three-dimensional model of the low thrust spacecraft, heliocentric trajectory of the spacecraft, the values of flight duration and propellant consumption during exploratory flight.

Nanosatellites (NS) are one of the fastest growing branches of spacecraft technologies. One of the attractive areas of application for such spacecraft is real-time low-orbit remote sensing of the Earth. This paper aims to develop a concept of a propulsion system (PS) and a maneuvering module (MM) for a CubeSat3U format low-orbit nanosatellite (NS), that would enable such spacecraft to maintain the required orbit altitude for a few weeks or months depending on insertion parameters. Requirements for the maneuvering module are stated. Helium, nitrogen and liquefied propane are considered as propellants. Modeling showed that helium provides the greatest specific impulse, but its density is too low to store a sufficient quantity. Under specified conditions, nitrogen may be able to provide required characteristics of the maneuvering module; specific impulse can be nearly doubled by heating the propellant to 700 °C with electric heaters.

Placing the service systems alongside the facade is not uncommon in architecture. This “inside-out” concept can be easily seen in buildings such as the Pompidou Center in Paris or the Llyod's building in London. However, a more modern approach was taken in Düsseldorf, Germany in 2008, the Capricorn House Medienhafen Düsseldorf. This building contains a unique device in its facade- called the i-modul, which was designed by GATERMANN + SCHOSSIG. This decentralized service module, located behind the red glass panels, is equipped with technology to control the building's temperature and air-quality. It also features an integrated lighting system with sound absorption and room acoustic elements. This special feature eliminates the need for traditional technology and allows for more flexible space within the building. This paper examines the energy efficiency of the i-modul device and its relationship to preceding architectural facades, it also proposes four facades for a tower design in the New York city context. With the US being one of the greatest energy consumers on the planet, this study highlights possible design approaches that can be applied along building facades to help reduce the consumption of energy.

The first level (L0) muon trigger of the ATLAS experiment will be upgraded to operate at the High Luminosity LHC. The selectivity of the current L0 muon trigger is limited by the moderate spatial resolution of RPC and TGC. The MDT chambers currently used for precision tracking will be therefore included to improve the momentum resolution and the redundancy. In the Phase-II scheme, the MDT trigger processors will receive MDT hits from the detectors and match them to the trigger candidates (seeds) from the RPC and TGC+NSW trigger chambers. These seeds provide a region of interest (RoI) and the identification of the bunch crossing from which the muon originated. This is the t0 for computing the MDT drift time from the arrival time of the hit. MDT hits matched to the RoI are then used by the MDT trigger algorithm to improve the momentum resolution, by forming track segments and joining them together for momentum determination. A hardware demonstrator of the MDT trigger processor, based on a common ATCA platform known as "APOLLO", is currently under production. It consists of two separate modules called the "Command Module" and "Service Module", and it is based on FPGA technology. A description of the explored algorithms for the MDT track reconstruction is presented. The achieved trigger performance allow to reconstruct muon tracks at the first-level with an average momentum resolution of about 6% and a trigger efficiency above 95% for muons with a transverse momentum of 20 GeV.

Drone delivery has a great potential to change the traditional parcel delivery service in consideration of cost reduction, resource conservation, and environmental protection. This paper introduces a novel drone fleet deployment and planning problem with uncertain delivery demand, where the delivery routes are fixed and couriers work in collaboration with drones to deliver surplus parcels with a relatively higher labor cost. The problem involves the following two-stage decision process: (i) The first stage determines the drone fleet deployment (i.e., the numbers and types of drones) and the drone delivery service module (i.e., the time segment between two consecutive departures) on a tactical level, and (ii) the second stage decides the numbers of parcels delivered by drones and couriers on an operational level. The purpose is to minimize the total cost, including (i) drone deployment and operating cost and (ii) expected labor cost. For the problem, a two-stage stochastic programming formulation is proposed. A classic sample average approximation method is first applied. To achieve computational efficiency, a hybrid genetic algorithm is further developed. The computational results show the efficiency of the proposed approaches.

Maintaining a competitive edge in today’s markets with short product life cycles and competitors quickly copying commercial success ideas is a significant challenge. Service organisations have to look for ways to quickly adapt to environmental changes and offer the most satisfying services to demanding and rushing customers. One of the possible ways to achieve these goals is to apply the principles of modular design to services. Although the modular design is widely used in the production of goods, its applicability to services has not yet been sufficiently researched. There is a lack of consensus on the terms used, there is no clear definition of the modular service system requirements, there are many doubts in the application of quantitative decision methods for modular service system management, and so forth. The article aims to identify the fundamental problems associated with the use of modular design for services. Based on the results of the analysis of the scientific literature, we propose a scheme describing the service system, and identify the important problematic issues related to the application of modular design to services. In this paper, we use methods of systematic analysis, abstraction, synthesis, and critical analysis. Article in Lithuanian.

The Orion European Service Module—Structural Test Article (E-STA) underwent sine vibration testing in 2016 using the Mechanical Vibration Facility (MVF) multi-axis shaker system at NASA Glenn Research Center’s (GRC) Plum Brook Station (PBS) Space Power Facility (SPF). The main objective was to verify the structural integrity of the European Service Module (ESM) under sine sweep dynamic qualification vibration testing. A secondary objective was to perform a fixed-base modal survey, while E-STA was still mounted to MVF, in order to achieve a test correlate the finite element model (FEM). To facilitate the E-STA system level correlation effort, a building block test approach was implemented. Modal tests were performed on two major subassemblies, the crew module/launch abort structure (CM/LAS) and the crew module adapter (CMA) mass simulators. These subassembly FEMs were individually correlated and then integrated into the E-STA FEM prior to the start of the E-STA sine vibration test. This paper summarizes the modal testing and model correlation efforts of both of these subassemblies and how the building block approach assisted in the overall correlation of the E-STA FEM. This paper will also cover modeling practices that should be avoided, recommended instrumentation positioning on complex structures, and the importance of the FEM geometrically matching CAD in sufficient detail in order to adequately replicate internal load paths. The goal of this paper is to inform the reader of the hard earned lessons learned and pitfalls to avoid when applying a building block test approach.

We have developed a novel and generic open-source platform - Apollo - which simplifies the design of custom Advanced Telecommunications Computing Architecture (ATCA) blades by factoring the design into generic infrastructure and application-specific parts. The Apollo "Service Module" provides the required ATCA Intelligent Platform Management Controller, power entry and conditioning, a powerful system-on-module (SoM) computer, and flexible clock and communications infrastructure. The Apollo "Command Module" is customized for each application and typically includes two large field-programmable gate arrays, several hundred optical fiber interfaces operating at speeds up to 28 Gbps, memories, and other supporting infrastructure. The command and service module boards can be operated together or independently on the bench without need for an ATCA shelf., Comment: Submitted to the Proceedings for TWEPP 2019

In recent years, great experience has been accumulated in manned flight astronautics for rendezvous in near-Earth orbit. During flights of Apollo spacecraft with crews that landed on the surface of the Moon, the problem of docking a landing module launched from the Moon’s surface with the Apollo spacecraft’s command module in a circumlunar orbit was successfully solved. A return to the Moon declared by leading space agencies requires a scheme for rendezvous of a spacecraft launched from an earth-based cosmodromee with a lunar orbital station. This paper considers some ballistic schemes making it possible to solve this problem with minimum fuel expenditures.

Manufacturing enterprises, manufacturing services and customer constitute the service-oriented manufacturing dynamic network (SMN). The quality of SMN mainly depends on the service module provider. Under the condition of information asymmetry in the market, service module provider pursuits for self-interest maximization, may take quality speculation. Based on the reputation incentive theory, this paper establishes an optimal SMN node quality behavior dynamic model of the contract which combines with dominant incentive mechanism and reputation incentive mechanism, discusses the factors which influence the service module provider’s effort level, the conditions of realizing effective reputation incentive and the ways to improve reputation incentive effect.

On this basis, functional modules of the platform are constructed, including data acquisition module, processing module, analysis module and service module of marine resources competitive intelligence, which realizes the operation of marine resources competitive intelligence data interactive sharing platform under the background of intelligent construction. The test results show that compared with the traditional platform for competitive intelligence data interactive sharing of marine resources, the constructed platform for competitive intelligence data interactive sharing of marine resources greatly enhances the maximum number of concurrent users, fully demonstrating that the platform has better performance.

Due to the personalized and diverse service needs, service scheme configuration should be more quick and flexible in the process of product service system (PSS) scheme design. Service modularization can effectively improve the service configuration efficiency and modules’ reusability. However, compared with the modularity of tangible products, the partition of service modules in the practical context is still a problem to be discussed. In this paper, a service partition approach for PSS based on the fuzzy graph and Dempster-Shafer theory of evidence is presented. Firstly, service activities correlation analysis is carried out, according to which the fuzzy graph is drawn. By setting different thresholds, the fuzzy graph is cut, and different partition results are obtained. Secondly, the evaluation indexes of customization, generalization, and technological evolution are proposed and used as evidence sources of the Dempster-Shafer theory of evidence. Through the synthesis of the evidence sources, the optimal partition scheme is got. Finally, to verify the method, a case study is illustrated through the NC machine tools module partition. And results show that the proposed method can provide specific ideas and concrete guidance of the service module partition.

This paper presents the definition of a Reference Application Architecture for the Customer Relationship Management (CRM) domain. The definition of the Reference Application Architecture is done by extracting best practices from five CRM commercial solutions: SugarCRM, Microsoft Dynamics CRM, Sage CRM, Oracle Siebel CRM and Salesforce CRM. The CRM Reference Architecture was developed considering the shared functionalities and information entities among these commercial solutions. In the Reference Architecture the authors identify six modules in the CRM system and five systems, which interact with the CRM system. The six CRM modules are: Account module, Sales module, Marketing module, Service module, Scheduler Module and Administration module. The five interacting systems are: Portal, Contact Center, Document and Knowledge Base Management system, Workflow system and Reporting and Analytics system. Then the authors apply the defined architecture in a case study from the Portuguese Public Administration, the Citizen Spaces provided by the Agency for the Administrative Modernization. The authors compare the current state of the Citizen Spaces with a possible architecture reached through the Reference Architecture, and assess the benefits and pitfalls of the purposed architecture.

Circumlunar return and reentry spacecraft accurately landed within the predetermined area in SiZiWangQi, Inner Mongolia on Nov. 1, 2014, which marks the successful completion of the reentry test in the third phase of ChangE lunar exploring project, and indicates that the key technology of deep space reentry return, as the speed of the spacecraft is close to the second cosmic velocity, is fully mastered by China. It ensures the smooth implementation of ChangE-5 program and lays a solid foundation of the lunar exploring project. During the flight control of circumlunar return and reentry spacecraft, the integrated digital flight control support system (IDFCS) is played a key role in ether flight control strategy development, simulation & validation and design optimization. In this paper, the principle and architecture design of the IDFCS for Spacecraft is proposed, and the key points of the system, such as acceleration of processor simulation, virtual chip modeling, automatic test script, general user interface, data dynamic interpretation, are analyzed. Finally, the practical effect of the IDFCS for circumlunar return and reentry spacecraft is present. The actual in-orbit validation shows that some of the satellite flight control problems, such as the complexity of constraints, the difficulty of strategy determination, are solved by the present system, and rich experience in both theory and engineering is accumulated for the subsequent development of the satellite flight control system.

The circumlunar return and reentry spacecraft has landed at the reserved landing site on Nov. 1, 2014, which represented the great success of the circumlunar return and reentry spacecraft of 3rd phase of China lunar exploration program. As a key step of the whole space mission, the guidance, navigation and control system of the spacecrafts service module sent the reentry capsule into the back corridor with the high-accuracy reentry angle and reentry velocity. This article introduces the wheel control attitude management technology, jet management technology and accelerometer closed-loop orbit control technology used to realize return and reentry to the earth within 11 km/s and solve the difficult problem of the accuracy requirement for the reentry angle and reentry velocity. The combination of these techniques was implemented on orbit, and obtained the orbit control accuracy higher than 0.009 m/s and the reentry angle control accuracy higher than 0.024°.

This paper describes the software architecture and design of the space segment, communication and ground segment software of the Kontur-2 project, which aimed to study the feasibility of planetary exploration through telepresence. The main research objectives in Kontur-2 were the development and in-flight verification of a space qualified two degree of freedom (DoF) force-feedback joystick (RJo) inside the Zvezda Service Module of the International Space Station (ISS), the implementation of telepresence technologies, and the study of human performance when controlling a force feedback joystick in microgravity. The project was conducted from 2012 to 2015 by a consortium consisting of the German Aerospace Center (DLR), the Russian Federal Space Agency (ROSCOSMOS), The Russian State Scientific Center for Robotics and Technical Cybernetics (RTC), S. P. Korolev Rocket and Space Corporation Energia (RSC “Energia”) and the Yuri A. Gagarin State Scientific Research-and-Testing Cosmonaut Training Center (GCTC). DLR conducted two sets of experiments in which a cosmonaut on board the ISS used RJo to perform different tasks with robots located on-ground. The first was conducted with a 2-DoF robot equipped with a camera system, a task board and torque sensors that allowed the cosmonaut to perceive reactive forces caused by contacts with the environment. For the second set of experiments a humanoid robot was utilized to perform a tele-handshake, as well as a cooperative task between the cosmonaut on ISS and colleagues at RTC in St. Petersburg. To realize these experiments, the consortium developed onboard and on-ground software which are described in this paper. The space segment software consists of the control software for RJo and user interfaces on a laptop to guide the cosmonaut efficiently through the experiments. A state machine was designed for these user interfaces to capture state changes during the experiment execution. This way only relevant contextual information is provided to the cosmonaut. On RJo, a component framework has been deployed combining a data-centric architecture with a CCSDS Space Packet interface. Additionally, the communication software has been designed to support a direct multi-channel connection between ground control and ISS using the S-band radio equipment of the consortium. During contact to ISS, the ground operators used the ground segment software at DLR for experiment support, supervision, maintenance and data logging. The visual feedback from the camera system required by the cosmonaut to perform the experiments was provided by a low-latency video stream through a communication channel with very restricted bandwidth. 23 experiment sessions were carried out in 2015 utilizing the Kontur-2 software, which helped to validate telepresence technologies and study human factors for space applications.

A decision support system (DSS) module for sustainable land development for Thailand: A case of Chonburi province was developed for decision makers based on available geographic information databases and overlaying techniques available on an internet network. Chonburi province in the Southeast Coast of Thailand was assigned as a special economic development zone or Eastern Economic Corridor (EEC) is a fast growing area for industrial and infrastructure developments causing land use conflicts between privates and governments that were observed elsewhere. Databases including administrative boundary, land resources, land uses, national policies and legislation aspects were integrated for land suitability, condition and limitation for land developments. The system employed ArcGIS Geo-processing service module available on the Central Relation Database that can be accessed via Web Services and RSS. The decision makers could access from the Web Browser and make decision under three conditions, by screening areas for specific land use types, analyzing land use limitations and conditions or for maximum land use benefits. The developed DSS module on land resources spatial analysis and legislation limitations would be a simple technological tool to preliminary and fast selection of proper land managements in the future and would be able to apply in other parts of the country.

Self-preparation in dealing with physical changes is a necessity for young women, and lack of preparation will lead to several problems such as; anxiety, fear, timidity, sleeplessness, loss of appetite, and disruption of adult development. Self-preparation can be improved through information services provided by counselors using appropriate media and materials. The ADDIE model was used in this research and six experts were employed as subjects to validate service guidelines based on the display of laid down principles. Three counselors were on standby to test the use of the guidelines, and a total of thirty students were tested. The descriptive and inferential analysis with the Kendall coefficient (W) test were used to perform the examination. Therefore the result of the study shows that the prototype information service module can be used to prepare young women for physical changes during puberty.

Nowadays, small to medium sized companies, which usually cannot afford hiring dedicated security experts, are interested in benefiting from Managed Security Services (MSS) provided by third party Security Operation Centers (SOC) to tackle network-wide threats. Accordingly, the performance of the SOC is becoming more and more important to the service providers in order to optimize their resources and compete in the global market. Security specialists in a SOC, called analysts, have an important role to analyze suspicious machine-generated alerts to see whether they are real attacks. How to monitor and improve the performance of analysts inside a SOC is a critical issue that most service providers need to address. In this paper, by observing workflows of a real-world SOC, a tool consisting of three different modules is designed for monitoring analysts' activities, analysis performance measurement, and performing simulation scenarios. The tool empowers managers to evaluate the SOC's performance which helps them to conform to Service-Level Agreement (SLA) regarding required response time to security incidents, and see the need for improvement. Moreover, the designed tool is strengthened by a background service module to provide feedback about anomalies or informative issues for security analysts in the SOC. Three case studies have been conducted based on real data collected from the operational SOC, and simulation results have demonstrated the effectiveness of the different modules of the designed tool in improving the SOC performance.

Euclid is a space-based optical/near-infrared survey mission of the European Space Agency (ESA) to investigate the nature of dark energy, dark matter and gravity by observing the geometry of the Universe and on the formation of structures over cosmological timescales. Euclid will use two probes of the signature of dark matter and energy: Weak gravitational Lensing, which requires the measurement of the shape and photometric redshifts of distant galaxies, and Galaxy Clustering, based on the measurement of the 3-dimensional distribution of galaxies through their spectroscopic redshifts. The mission is scheduled for launch in 2020 and is designed for 6 years of nominal survey operations. The Euclid Spacecraft is composed of a Service Module and a Payload Module. The Service Module comprises all the conventional spacecraft subsystems, the instruments warm electronics units, the sun shield and the solar arrays. In particular the Service Module provides the extremely challenging pointing accuracy required by the scientific objectives. The Payload Module consists of a 1.2 m three-mirror Korsch type telescope and of two instruments, the visible imager and the near-infrared spectro-photometer, both covering a large common field-of-view enabling to survey more than 35% of the entire sky. All sensor data are downlinked using K-band transmission and processed by a dedicated ground segment for science data processing. The Euclid data and catalogues will be made available to the public at the ESA Science Data Centre., Comment: 23 pages, 19 figures, Presented at the SPIE Astronomical Telescopes and Instrumentation conference in Edinburgh, Scotland, United Kingdom, 6 June 1 July 2016
