The Office of Technology, Planning, and Integration for Observation (TPIO) maintains gap analysis tools that are used to compare both observing system attributes and the National Oceanic and Atmospheric Administration (NOAA) User Observation Requirements to help answer NOAA-wide business questions regarding observational needs and investment. Using the information connected to NOAA products, a capabilities...
With the rapidly increasing reliance of life sciences research on digital data and sophisticated computational analysis techniques, the ability to reproduce findings generated by in-silico data analysis workflows is of increasing importance to the scientific community. However, challenges to reproducibility arise from the heterogeneity of approaches available to workflow definition and enactment....
The RE@40 seminar offered a diagnosis of the state of RE as it enters its 40s. At 40, RE has grown up a bit and should have a clear sense of who it is as it moves deeper into its most productive years. Of course, many 40-somethings also begin to experience a midlife crisis and suddenly change direction, perhaps not attending well to their current responsibilities. Where does RE sit at this juncture?
Several observations at industry examples have shown that there is a need to close an existing gap between system architect's model and domain experts' models. Therefore, a minimalistic approach is presented, which allows integrating executable domain models into a system model using a state of the art Model Based Systems Engineering (MBSE) authoring tool. Such MBSE approaches and tools offer possibilities...
The paper defines the main causes of impermissible dynamic loads in the shaft assemblies of a horizontal plate mill stand. It substantiates the development and commercialization of a stationary telemetry system for continuous control of the torque of the shaft assemblies at the 5,000 mm mill stand at Magnitogorsk Iron and Steel Works, OJSC. The authors determine the main system functions and list...
Global Navigation Satellite Systems (GNSS) have been widely used in safety-related applications, for example, railway train control systems. Starting from the application of GNSS technology in railway train location, this paper analyzes the necessity of GNSS performance assessment based on the actual needs of train positioning. First, the application status of GNSS in train positioning at home and...
The ongoing trend towards distributed development activities causes a growing need for specification activities and techniques. Each component leads to a large number of specification documents being exchanged, change managed and committed. The quality of the specifications influences the timing, costs and success of the development task. However, the quality of such specifications is often far from...
It is sometimes a challenge to access to specific skills assessments and training programs for children with special needs. In the case of visual perception, and more specifically eye-motor coordination, methods like the Frostig one are not adapted to all children. In this paper, we present a two steps co-design process with therapists and children in order to come up with an alternative solution...
Requirements are the keystone of complex systems development. In order to reduce inconsistencies, requirements analysis is an important issue of systems engineering. In this context, there is a need for conciliating views of several stakeholders from different domains and for tracing these requirements from specification to realization. The computerization of analysis, with the help of a clearly defined...
With the advance of modern technologies, computer-based systems for animals are gaining popularity. In particular, there is an explosion of products and gadgets for pets: wellness monitoring applications (e.g., FitBark and PetPace), automatic food dispensers, cognitive enrichment apps, and many more. Furthermore, the discipline of Animal-Computer Interaction has emerged, focusing on a user-centric...
Privacy laws and international privacy standards require that companies collect only the data they have a stated purpose for, called collection limitation. Furthermore, these regimes prescribe that companies will not use data for purposes other than the purposes for which they were collected, called use limitation, except for legal purposes and when the user provides consent. To help companies write...
As part of a research project that aims at proposing a new methodology for defining a series of rules for writing good requirements – often referred to as a Controlled Natural Language (CNL) – for the French Space Agency (CNES, Centre National d'Études Spatiales), we asked both experienced engineers and non-experts to fill in an online questionnaire in order to gather their perception about requirements...
In this paper, we take up the second RE17 data challenge: the identification of requirements types using the "Quality attributes (NFR)" dataset provided. We studied how accurately we can automatically classify requirements as functional (FR) and non-functional (NFR) in the dataset with supervised machine learning. Furthermore, we assessed how accurately we can identify various types of NFRs,...
Although information retrieval advances significantly improved automated traceability tools, their accuracy is still far from 100% and therefore they still need human intervention. Furthermore, despite the demonstrated benefits of traceability, many practitioners find the overhead for its creation and maintenance too high. We propose the Behavior Driven Traceability Method (BDT) that takes a different...
In order to effectively develop AAL solutions, it is crucial to analyse user requirements. The determination of actual user needs can make the difference between a nice to have and a real innovation. Integrating the target group successfully means being able to detect requirements and errors as well as needs, fears and barriers and utilize creative potential. The main advantage of such testing is...
Creating new software or software-intensive systems is still a challenge and far removed from a traditional engineering domain. The increasing size of software deployed in typical systems and the emergence of very large highly distributed systems necessitates additional techniques to assure the systems' quality. Using the example of the German automatic toll system we introduce and discuss a simulation...
Business Models (BMs) are in focus of research and practice for many years. These are representations of an organisation's business activities that intercede between business processes and strategy. Typically, industries that are supported by or based on information technology are in the focus for setting up BMs as dynamic business environments require such anchor points. Business Model Representations...
The Thermal InfraRed Sensor (TIRS), an infrared (IR) radiometer developed at Centro de Astrobiología, is one the sensors that compose the Mars Environmental Dynamics Analyzer (MEDA) onboard NASA's Mars 2020 mission. It will measure the net thermal infrared radiation, reflected solar radiation at the surface, atmosphere temperature and surface skin brightness temperature using five different channels...
The adoption of agile methods is difficult. No rework metrics, changing scope and requirements are the main difficulties in adopting these. In this sense, the Trace++ approach aims to facilitate the adoption of agile methods by teams that work with traditional methods. However, to obtain use-scale, this paper proposes a tool to facilitate the requirements traceability processes, in order to scale...
