TL;DR: A platform concept is depicted, which combines cloud computing and industrial control using edge devices realized for an automation cell, which opens up new potentials in the industrial sector.
Abstract: In the past, industrial control of field devices was comprised of self-contained systems in a dedicated network for exchanging control information between field devices and control hardware to accomplish process tasks. Nowadays, cloud computing enables a massive amount of computing resources and high availability, which opens up new potentials in the industrial sector. Until now, the integration of cloud solutions in industrial control was limited due to missing technologies connecting the Internet of Things with industrial requirements. Furthermore, based on existing paradigms there is a lack of appropriate architecture concepts for industrial control. This paper depicts a platform concept, which combines cloud computing and industrial control using edge devices realized for an automation cell.

TL;DR: In this article, a mini portable cooler that utilizes the Peltier effect to cool the human expressed breast milk (EBM) within 24 hours at the temperature range between 4°C-15°C to maintain the high quality of the EBM for use at a later date and the health of the baby who consume it.
Abstract: This paper presents the design and development of a mini portable cooler that utilizes the Peltier effect to cool the human expressed breast milk (EBM) within 24 hours at the temperature range between 4°C-15°C to maintain the high quality of the EBM for use at a later date and the health of the baby who consume it. It is developed to overcome the tediousness of using cooler bag/box, which requires ice packs that need repetitive freezing. A few prototypes with different sizes and body materials, namely polystyrene, polypropylene and aluminium, were successfully developed and tested to get the minimum temperature using 5V power supply. In all graphs, the temperature is decreasing with time. The smallest size of the cooled space (18cm of width, 12cm of length and 14cm of height) has the lowest temperature compared to the other sizes for each body material. However, the lowest temperature of all body materials is obtained from aluminium with 11.2°C at 100 minutes. It also reaches below 15°C the fastest which is at 80 minutes compared to the other prototypes that need longer time. All in all, aluminium is the best body material for the mini portable cooler developed in this project.

Abstract: Thanks to a coordinated funding by the European Space Agency (ESA) and the European Commission (EC) within the 7th framework program, the High-Speed Experimental Fly Vehicles – International (HEXAFLY-INT) project is aimed at the flight validation of hypersonics technologies enabling future trans-atmospheric flights. The project, which is currently involving partners from Europe, Russian Federation and Australia operating under ESA/ESTEC coordination, will achieve the goal of designing, manufacturing, assembling and flight testing an unpowered high speed vehicle in a glider configuration by 2018. The main technical challenges of the project are specifically related to the design of the vehicle gliding configuration and to the complexity of integrating breakthrough technologies with standard aeronautical technologies, e.g. high temperature protection system and airframe cold structures. Also, the sonic boom impact, which is one of the environmental challenges of the high speed flight, will be assessed. This paper provides a comprehensive and detailed update on all the current projects activities carried out to date on both the vehicle and mission design.

Hybrid Theorem Proving of Aerospace Systems: Applications and Challenges

[...]

Ghorbal, Khalil, Jean-Baptiste Jeannin, Platzer, André, Gordon, Geoffrey J.
30 Jun 2018
Abstract: Complex software systems are becoming increasingly prevalent in aerospace applications: in particular, to accomplish critical tasks. Ensuring the safety of these systems is crucial, as they can have subtly different behaviors under slight variations in operating conditions. This paper advocates the use of formal verification techniques and in particular theorem proving for hybrid software-intensive systems as a well-founded complementary approach to the classical aerospace verification and validation techniques, such as testing or simulation. As an illustration of these techniques, a novel lateral midair collision-avoidance maneuver is studied in an ideal setting, without accounting for the uncertainties of the physical reality. The challenges that naturally arise when applying such technology to industrial-scale applications is then detailed, and proposals are given on how to address these issues.

TL;DR: Design and construction requirements for façade integration of building services TLDR: The main perceived problems for building services integration in facades at design, production and assembly stages are coordination issues among different disciplines and stakeholders, costs, lack of knowledge, physical integration issues during production and assembly stages, and barriers derived from unreliable performance and technical limitations of current products.
Abstract: The integration of decentralised building services into façade components presents advantages from functional and constructional standpoints. However, this integrated approach has not been massively implemented, having only stand-alone buildings and façade concepts as examples.This chapter delves into the requirements for integration within the façade development process, aiming to identify the main perceived problems for building services integration in facades at design, production and assembly stages. The employed method was an exploratory survey addressed to professionals involved in the development of façade systems for office buildings, at different stages, in order to generate new knowledge based on practical experience. The survey was conducted from mid-September to mid-November, 2015 and was distributed both as an online form and in printed format among several professional networks. Results show that the main problems refer to the overall process, particularly regarding coordination issues among different disciplines and stakeholders, while other problems such as costs and lack of knowledge, while still relevant, have more impact on particular stages. Among relevant problems related to the products themselves, the results show physical integration issues during production and assembly stages, and barriers derived from unreliable performance and technical limitations of current products to be integrated in façade systems.

TL;DR: GANIL facility upgrades its capabilities in nuclear physics with new projects, including Spiral2, leveraging Epics control system framework, with development progression from initial beam tests to whole machine tuning and commissioning.
Abstract: The GANIL facility is drastically extending its possibilities with new projects, so increasing its capabilities in nuclear physics. The most significant one is the Spiral2 installation based on a linear accelerator, then to be associated with the S3, NFS and DESIR new experimental rooms. Beside of the legacy home made control system handling the original installation, Epics was chosen as the basic framework for these projects. First, some control system components were used during preliminary beam tests. In parallel, the whole architecture was designed while the organization for future operation started to be considered; also, more structured and sophisticated tools were developed and the first high level applications for the whole machine tuning started to be tested, jointly with the current onsite beam commissioning. Progression of the control system development is presented, from the first beam tests up to the whole Spiral2 commissioning. Then, according to the new projects to cope with, some highlights are given concerning the related organization as well as specific items and developments to be considered, taking benefit from the Spiral2 control system feedback experience.

Cloud Based Implementation of a Gas Turbine Remote Monitoring System

[...]

7 May 2018
Abstract: <p>Vericor Power Systems is introducing remote performance monitoring capabilities for their aero-derivative commercial marine and industrial gas turbine product lines. Historically, Vericor has been focused primarily as an OEM of military marine engines and is now looking to expand their footprint into non-military markets. The expectation from industrial customers is that remote performance monitoring is not only a desired feature, but a necessary minimum capability. Vericor has provided custom remote monitoring solutions on an as needed basis in the past. However, in order to stay competitive, the need was identified to provide a standardized remote performance monitoring offering. A development program was initiated with the intent to rapidly bring to market a robust, quick to deploy solution. During the conceptual design phase, existing technologies were evaluated for suitability as a platform for data storage and analytics. Traditional solutions relied on the incorporation of a network server housed within Vericor’s corporate IT infrastructure for field data collection. A data historian software package would be used for analytics and reporting functions. Recent trends in the internet technology space have made cloud computing more prevalent than ever. Cloud based platforms were evaluated during the conceptual design phase and were found to have several advantages over corporate based servers. Ultimately Vericor elected to proceed with the development of a cloud based platform for their remote performance monitoring system. This paper dives into the selection process, reviewing the relative strengths and weaknesses of each platform type in the areas of availability, maintainability, analytic capability and cyber security.</p>

Abstract: Current building sector is focused on reduction of energy requirements, on renewable energy generation and on regeneration of existing urban areas. These targets need to be solved with a systemic approach, considering several aspects simultaneously such as climate conditions, lighting conditions, solar radiation, PV potential, etc. The solar access analysis is an already known method to analyze the solar potentials, but in current years, simulation tools have provided more effective opportunities to perform this type of analysis, in particular in the early design stage. Nowadays, the study of the solar access is related to the easiness of the use of simulation tools, in rapid and easy way, during the design process. This study presents a comparison of three simulation tools, from the point of view of the user, with the aim to highlight differences in the easy-to-use of these tools. Using a real urban context as case study, three tools; Ecotect, Townscope and Heliodon, are tested, performing models and simulations and examining the capabilities and output results of solar access analysis. The evaluation of the ease-to-use of these tools is based on some detected parameters and features, such as the types of simulation, requirements of input data, types of results, etc. As a result, a framework is provided in which features and capabilities of each tool are shown. This framework shows the differences among these tools about functions, features and capabilities. The aim of this study is to support users and to improve the integration of simulation tools for solar access with the design process.

Estimation of Operational Properties of Information Technology Usage and Dynamic Capabilities Indicators

[...]

Geida, Alexander
16 Nov 2018
Abstract: The article outlines conceptual and corresponding formal models that provide means for estimation of dynamic capabilities indicators of systems and operational properties of information technology usage of these systems performance. Dynamic capability is the ability of a system to adapt to changes of the systems environment. The use of information technologies plays a central role in developing such capability of a system. Operational properties indicators of IT usage (such as efficiency, effectiveness, capabilities) defined as a kind of system operational properties indicators under conditions of changing environment in such a way that it is possible to estimate their values analytically. Such estimation is fulfilled through plotting the dependences of predicted values of operational properties of IT usage against variables and options of problems solved. To develop this type of models, the use of information technologies during system functioning is analyzed through an example of a technological system. General concepts and principles of modeling of information technology usage during operation of such systems are defined. An exemplary modeling of effects of technological information and related technological non-information operations of technological systems operation is provided. Based on concept models of operation of technological systems with regard to information technologies usage, set-theoretical models followed by functional models of technological systems operation using information technologies are introduced. An example of operational properties indicators estimation is considered based on ARIS diagramming tools usage.

TL;DR: A multidisciplinary design optimization tool for spacecraft equipment layout conception automates the process of equipment placement, generating many possible trade-off solutions based on geometric dimensions, mass, heat dissipation, and available positioning area.
Abstract: ABSTRACT: One issue the design team has to face in the process of building a new spacecraft, is to define its mechanical and electrical architecture. The choice of where to place the spacecraft´s electronic equipment is a complex task, since it involves simultaneously many factors, such as the spacecraft's required position of center of mass, moments of inertia, equipment heat dissipation, integration and servicing issues, among others. Since this is a multidisciplinary task, the early positioning of the spacecraft´s equipment is usually done "manually" by a group of system engineers, heavily based on their experience. It is an interactive process that takes time and hence, as soon as a feasible design is found, it becomes the baseline. This precludes a broader exploration of the design space, which may lead to a suboptimal solution, or worse to a design that will have to be modified later. Recently, it has been shown the potential benefits of automating the process of spacecraft´s equipment layout using optimization techniques. In this paper, a prototype of an Excel® based tool for multidisciplinary spacecraft equipment layout conception is described. Provided the geometric dimensions, mass and heat dissipation of the equipment, and the available positioning area, the tool can automatically generate many possible trade-off solutions for the layout. It allows the user to set specific equipment to specific areas of positioning, and different combinations of objective functions can be used to drive the design. The features of the tool are shown in a simplified three dimensional problem.

Models Of It-Project Management

[...]

14 Nov 2018
Abstract: Information system project management (IT - project) is a complex iterative process. An important role for the development of complex IT projects plays records of the development lifecycle (LC). The article presents an analysis of the effectiveness of the work on the creation of IT - projects based on two modified models of the life cycle: cascade and spiral. Analysis of the effectiveness of the management of the IT project was implemented on the basis of simulation. The modeling was carried out on the basis of Any Ljgic tools on the example of development of geoinformation system (GIS). It is shown that it is advisable to design GIS on the basis of a modified spiral LC with splitting of the flow of requirements at the input. The peculiarity of the proposed study is to take into account the requirements in the form of communicative interactions of different types. Under the communicative interactions are understood all the interactions between the subjects of the process of creating an IT-project: verbal and non - verbal, carried out on the basis of CASE-means.

TL;DR: The ESFR-SMART project utilizes a 3D CAD model to enhance design, communication, and development of the European Sodium Fast Reactor, providing accurate measurements, data on physical properties, and input for research tools and system codes, with potential for future research and visualization applications.
Abstract: As part of the Horizon 2020 European Union programme, research and development is under process on the European Sodium Fast Reactor in the framework of the European Sodium Fast Reactor Safety Measures Assessment and Research Tools (ESFR-SMART) project. In this project, a large commercial pool type sodium-cooled fast reactor is under development which requires state of the art research tools. One of the new approaches is the use of Computer Aided Design (CAD) software in which a 3D CAD model was developed, based on open literature, and has already proven its usefulness in many ways during the project. But the possibilities are only scratching the surface. As it is mainly a design tool, it has been used mostly to create the 3D design of the whole reactor system with its sub-systems. Through this process, the visualization of the project gave an unprecedented ease to the understanding of different concepts for project members, allowed to improve communication between the partners and finally helped to decrease the time needed for the development of the reactor system. In particular, this ease of visualization made it possible to assess new design ideas and whether they fit the existing space around the primary system of the ESFR. The CAD model serves as a basis for accurate physical measurements as well as to provide data on different physical properties such as material volumes, surfaces areas, etc. Next, this feature of the model has been used already in the project to provide information for the core catcher design’s criticality calculation as well as data about sodium volume to facilitate the reactor pit preliminary design. Among further possibilities of the model is time saving by providing already available input information for other research tools and system codes. For instance, detailed geometrical data can be provided for thermal hydraulic CFD (e.g. OpenFOAM) or neutronics Monte Carlo (e.g. Serpent) codes. Furthermore, the model serves as a common base for any kind of design change to keep track of the latest version of the design which helps documenting the project, providing instant access to the needed information. In addition, the CAD software employs built-in modules which provide greater visualization by making available the creation of videos of the reactor for demonstration purposes or even to use other technologies such as 3D printing to present the work on the project to the other researchers or to public. These possibilities show the originality and usefulness of a 3D CAD model and the new dimensions for future research activities.

Intelligent Data Understanding for Architecture Analysis of Entry, Descent, and Landing: Applications for Mars Missions

[...]

23 Oct 2018
Abstract: Because Entry, Descent and Landing (EDL) system validations are limited in Earth environments, these technologies rely heavily on modeling and analysis tools to evaluate system performance and capture uncertainties, which determine the success of a mission. However, the current approach suffers from an important limitation. While the subject matter expert can leverage his or her knowledge and expertise with past systems to identify areas of risk and features of interest in the datasets available, the next generation of EDL systems may present unprecedented challenges that may be missed by the human. Landing humans on Mars, for example, will pose unprecedented challenges to EDL technologies driven by the need to land larger payload mass with extremely high reliability and safety requirements. The goal of this research is to advance the state of the art for offline Intelligent Data Understanding (IDU) technologies for Entry, Descent and Landing (EDL) by incorporating an intelligent assistant- called Daphne/EDL - that supports humans in architecting problems specific to the field of EDL. In this thesis, we describe a first prototype of the Daphne/EDL assistant in the context of three use cases to cover a range of representative problems in EDL architecture analysis and to show the capabilities of the assistant to support those use cases. Specifically, we demonstrate the baseline functionalities of the EDL assistant that include: 1) preliminary analysis capabilities of simulation datasets; 2) extraction of performance metrics from a historical database; and 3) automated generation of a scorecard. The scorecard contains metrics critical to assess EDL architecture performance. The assistant highlights metrics that fall out of spec of a design and communicates them to the subject-matter expert.

Phases of a pigging project (pre-commissioning, cleaning, in-line inspection and maintenance), planning and project execution are addressed. This document compliments the other reports produced as part of PRCI project SPDA-1-4, which focus on subsea pig launching and receiving.

TL;DR: This study applies signal processing theory to determine the optimal sampling size for geostatistical data using a Gaussian variogram model, aiming to reconstruct population maps with regularity conditions verified, including stationarity and isotropy.
Abstract: Na Geoestatística Clássica existe uma grande necessidade de pesquisas que criem e/ou investiguem métodos de amostragem de dados geoespaciais. Além da complexidade do assunto, alguns trabalhos apresentam soluções que utilizam mecanismos teóricos e práticos de diferentes áreas do conhecimento científico que atendem demandas específicas de pesquisadores da área. O objetivo deste artigo é utilizar a Teoria da Informação de Sinais Elétricos, principalmente considerando o Teorema da Taxa de Nyquist, para determinar um tamanho ótimo para amostras georreferenciadas que usam grade quadrática regular, no qual o modelo de dependência espacial é o gaussiano. O que se deseja alcançar teoricamente é uma densidade de amostragem necessária para a reconstrução de mapas populacionais de variáveis nas quais as condições de regularidade necessárias em geoestatística foram verificadas, a saber: estacionariedade de 1a e 2a ordem e/ou estacionariedade do variograma, ausência de outliers e tendências, e variograma isotrópico. Como resultado, pode-se afirmar que a distância máxima entre os pontos da grade regular quadrática é de aproximadamente 30% do alcance prático observado no variograma da primeira amostragem experimental.

Abstract: The successful realization of complex systems is dependent not only on the technology issues and the process for implementing them, but on the management issues as well. Managing the systems development lifecycle requires technical management. Systems engineering management is the technical management. Systems engineering management is accomplished by incorporating many activities. The three major activities are development phasing, systems engineering process and lifecycle integration. Systems engineering management activities are performed across the system development lifecycle. Due to the ever-increasing complexity of systems as well the difficulty of managing and tracking the development activities, new ways to achieve systems engineering management activities are required. This paper presents a systematic approach used as a design management tool applied across systems engineering management roles. In this approach, Transdisciplinary System Development Lifecycle (TSDL) Model has been modified and integrated with Quality Function Deployment. Hereinafter, the name of the systematic approach is the Transdisciplinary Quality System Development Lifecycle (TQSDL) Model. The QFD translates the voice of customers (VOC) into measurable technical characteristics. The modified TSDL model is based on Axiomatic Design developed by Suh which is applicable to all designs: products, processes, systems and organizations. The TQSDL model aims to provide a robust structure and systematic thinking to support the implementation of systems engineering management roles. This approach ensures that the customer requirements are fulfilled as well as satisfies all the systems engineering manager roles and activities.
