Development of a Software Package Architecture for Simulation and Prototyping of Radar Systems and Complexes

Introduction. Computer simulation and prototyping software can simplify the design process of complex information and measurement systems significantly, including radar systems and complexes. At present, a number of software packages are used to solve these problems to varying degrees. However, these software packages are either versatile, thus being incapable of taking the specifics of radar operation into account and requiring hand-made implementation of mathematical models for simulating radar signals, or are aimed at a narrow range of prototyping problems and algorithm development for processing radar information for a strictly defined radar type (or even a specific model). Some software packages, such as MATLAB, offer extension packages that allow radar signal simulation for automotive radars, as well as radar signal processing; however, these packages cannot cover the full range of simulation and prototyping tasks.Aim. Analysis of current software packages for simulation and prototyping of radar systems and complexes, justification of the demand and development of the concept and architecture of a software package for simulation and prototyping of radar systems and complexes.Materials and methods. Systems approach, architectural and conceptual software design, system analysis, criterion analysis. Results. The criteria that software packages for simulating and prototyping of radar systems and complexes must meet were determined. A comparative analysis of the existing approaches and software packages that solve problems arising at various stages of radar development was carried out. A list of requirements for such a software package was compiled, its concept and architecture was developed, and some features of its implementation were determined.Conclusion. The developed architecture allows creation of a versatile software package which could provide solutions to the problems of simulation and prototyping of radar systems and complexes using a single software package. The applied principles of modularity and decomposition ensure versatility and a high potential for adapting software modules, including for creating software for controlling radar prototypes and visualizing radar data in real time.

Development of a multifunctional real-time data processing system for interferometers on EAST

In the latest campaign of EAST experiments, two new interferometers were installed, a dispersion interferometer (DI) based on a Carbon Dioxide laser and a solid source interferometer (SSI) based on microwave multiplier sources. To make them available for the Plasma Control System (PCS) system, each of them needs to be provided with a real-time processing system to extract the detector output signal and afterward obtain the electron density information through signal processing. To obtain interferometer data quickly and reliably, a unified hardware template was applied to both interferometers. Three main parts are included in this hardware template — digitization, digital signal processing, and output modules. In particular, the digitization section uses a multi-channel Analog-to-Digital Convertor (ADC) to acquire the signals that need to be calculated. The digital signal processing part is implemented by an FPGA, which is the hardware basis of this multifunctional template that can be used for multiple interferometers. This section includes two main parts, wrapped density signal extraction and signal unwrapping. For DI it is a phase calculation based on the intensity ratio, while for SSI it is a phase calculation by means of FFT or phase demodulation. Both computational approaches form independent IP cores to build systems quickly, while these IP cores provide parameter interfaces to adapt to different application scenarios. The output module provides a variety of data transmission methods, including fiber optic transmission and Digital-Analog-Convertor (DAC) based analog transmission, to interface with PCS or other subsequent systems.This data processing system template has been applied to each of the above two interferometers and valid data were obtained in a recent EAST experiment campaign. It demonstrates the usefulness of the template and provides a reference for the design of data processing systems on future devices.

Natural Language–Based Conceptual Modelling Frameworks: State of the Art and Future Opportunities

Identifying requirements for an information system is an important task and conceptual modelling is the first step in this process. Conceptual modelling plays a critical role in the information system design process and usually involves domain experts and knowledge engineers who brainstorm together to identify the required knowledge to build an information system. The conceptual modelling process starts with the collection of necessary information from the domain experts by the knowledge engineers. Afterwards, the knowledge engineers use traditional model driven engineering techniques to design the system based on the collected information. Natural language–based conceptual modelling frameworks or systems are used to help domain experts and knowledge engineers in eliciting requirements and building conceptual models from a natural language text. In this article, we discuss the state of the art of some recent conceptual modelling frameworks that are based on natural language. We take a closer look at how these frameworks are built, in particular at the underlying motivation, architecture, types of natural language used (e.g., restricted vs. unrestricted), types of the conceptual model generated, verification support of the requirements specifications as well as the conceptual models, and underlying knowledge representation formalism. We also discuss some future research opportunities that these frameworks offer.

Design process knowledge for crisis‐driven information systems solutions: Insights on building digital resilience from an action design research study

AbstractAs global disruptions escalate, digital resilience (DR)—the capacity to anticipate, absorb, and adapt to external shocks by leveraging Information Systems (IS)—has become crucial for individuals and organisations confronting and managing unprecedented crises. This research advances understanding on how to develop DR, drawing on insights from an Action Design Research (ADR) study conducted during the COVID‐19 pandemic. Our research explores a particular facet of DR: the capacity to manage exogenous shocks through the design of new IS solutions. We introduce the ADAPT framework, comprising five key enablers—Agility, Designation, Alignment, Participation, and Trust—recommended to support design teams developing IS solutions during and for crises. Our ADR project, which resulted in the creation of a telemonitoring system used by over 115 frontline healthcare workers to monitor the symptoms of more than 1000 COVID‐19 patients, demonstrates the instrumental role these five enablers play in supporting a crisis‐propelled IS design process that is urgent, resource‐limited, and multi‐partite. By presenting new design process knowledge and practical recommendations that guide crisis‐driven IS design, we aim to equip design teams with the understanding they need to effectively navigate similar challenges in the future. We also hope to inspire and support IS researchers to apply their expertise in the design, deployment, and use of IS solutions to contribute to crisis‐driven design endeavours that tackle the pressing and urgent challenges of our time.

User involvement into the information system design process based on the use of architectural schemes

One of the problems in the field of design and development of information systems remains the problem of transition between models of the subject area and models of the information system. To solve this problem, the concept of involving the end user (domain expert) in the development process is currently being applied. It is assumed that the end user is the main source of knowledge about the subject area, while he has practically no knowledge about the system. On the other hand, the development team has an opposite relationship between domain knowledge and system knowledge. The article discusses in detail the existing models of involving the end user in the process of developing information systems. On the basis of the identified shortcomings, a new model is proposed that does not require additional user knowledge when describing models of the system (the system itself) and allows the user to describe his professional activities in a unified form and in natural language. The article also shows the application of this model, on one of the aspects (development of data transformation logic).

Conceptualising the relationship types and attributes that enable stakeholders to recruit SME farmer users into IS design

It can be difficult for organisations which develop an information system (IS) for use by many small and medium enterprises (SMEs) to recruit SME personnel during IS design. The paper addresses this problem by exploring the nature of relationships that organisational stakeholders can use to recruit SME personnel during IS design, which has received little attention in the literature. We present an interpretive, revelatory case study of the insights from managers and field officers who recruited SME farmers during the design of an inter-organisational IS. We identified three relationship types, based on an existing framework in the literature derived from stakeholder theory: between managers of organisations; between managers and field officers; and between field officers and farmers. We extend this framework by incorporating relationship attributes based on social capital concepts: ties, shared cognition, structure, homophily and bridging capital. We found that the complex interplay of the three relationship types, and the degree of strength of the social capital attributes of these relationships, help explain how farmers were recruited into, or were discouraged from participating in, a lengthy IS design process.

Study of influence of test case parameters on test suite optimality in order to automate the information systems design process

The paper presents data on the influence of test parameters like average execution time, number of runs, test’s severity and complexity, number of related bugs on test’s optimality to include a test set for regression testing of information system software components. The paper includes research using such methods as analysis of variance, correlation and regression analysis of test parameters. The studies have shown a degree of the influence of test’s parameters to test suite efficiency and optimality in order to perform regression testing. Solving the problem of creation of optimal test suites aimed at regression testing gives a chance to automate the information systems design process.

An Exploration of Resilience and Values in the Co-Design of Sociotechnical Systems

The notion of resilience is becoming an important consideration in addressing the needs of vulnerable individuals and groups in the public sector. In Information Systems development, resilience has often been treated as a non-functional requirement such as scalability and little or no work has aimed at building resilience in end-users through systems development. Sociotechnical approaches while not specifically addressing resilience, have strived for a balance between technology and humans. While there are many variants of sociotechnical approaches, in this paper the authors introduce a refinement of the value sensitive action-reflection model used in co-design, first introduced by Yoo et al, that recognises the tension between values and resilience. The authors report on their activities of using this approach for a project aimed at developing mobile apps for promoting better engagement between young people in conflict with the law and their case workers in the UK youth justice system. They examine the ambiguity created when designer and stakeholder prompts change their role and purpose during the co-design process and discuss the impact of this on resilience building for the end-user and the possible implications for Information Systems design processes.
