The impact of the new space economy on sustainability: an overview

The first overarching objective of the Space Agenda 2030 is to strengthen the role of the space sector as a major driver of sustainable development. To achieve this objective, the European Space Agency launched already 10+ years ago the ESA Business Applications Programme to foster the adoption of space technologies in non-space sectors, promoting the development of commercial satellite-based projects (i.e., projects developing business applications based on Earth Observation, Satcom and Navigation satellite technologies and data) and contributing to achieving Sustainable Development Goals (SDGs).While space technologies undeniably offer substantial societal benefits, there exists an opportunity to provide professionals and academics with a comprehensive perspective on the ongoing progress of commercial satellite-based projects in their vital role in advancing the achievement of Sustainable Development Goals (SDGs) and tackling Grand Challenges. Our research aims to clarify commercial satellite-based applications' direct and indirect impacts on SDGs and their features contributing to achieving them.We develop a taxonomy of the ESA Business Applications programme portfolio, analysing 603 commercial satellite-based applications developed between 2014 and 2022 across 34 variables (including SDGs directly or indirectly impacted), sourced from the program's web pages. We perform descriptive statistics and exploratory data analysis to present commercial satellite-based applications' direct or indirect impact on the 169 SDG targets. Finally, we describe the features of commercial satellite-based projects (e.g., geographical scope, satellite technology adopted, non-space domains of application) contributing to the SDGs' achievement.Our results show that 603 commercial satellite-based applications impact at least one SDG. Overall, SGD3 is the most impacted (136, 22 %), followed by SDG11 (105, 17 %) and SDG2 (78, 12 %). 257 Earth Observation-based applications mostly impact SDG2 (58, 23 %), SDG15 (38, 15 %) and SDG11 (34, 13 %). 230 Satellite Navigation-based applications mostly impact SDG3 (68, 30 %), SDG11 (52, 23 %) and SDG6 (22, 10 %). 116 Satellite communication-based applications mostly impact SDG3 (33, 28 %), SDG11 (16, 14 %) and SDG4 (15, 13 %). Moreover, we identify 14 application domains, and for each of them, we investigate their impact on SDGs. The application domains that mainly impact SDGs are Health (91, 16 %), Food and Agriculture (85,15 %), and Energy (51, 9 %).Our research demonstrates and strengthens the space sector's role as a major driver of sustainable development. Researchers may adopt the methodology in other contexts, overcoming the geographical and data accessibility limitations of our research.

Computing in the cloud can assist businesses in shifting their focus to the development of solid business applications that will bring about genuine value to the businesses. Green computing, often known as environmentally sustainable computing, is the definition of green computing. It is a reference to the efforts that are made to maximise the usage of power consumption & energy efficiency while simultaneously minimising the cost & the amount of CO2 emission. To conduct a study on optimisation techniques & procedures that assist us in optimising low energy consumption & evaluating multiple parameters in order to obtain the desired output is the primary purpose of this research. Energy-Conscious Multisite Computation Offloading Techniques (EMOGC) for Green Cloud Computing is the methodology that was utilised throughout this project. Simulation & analysis are presented in The Energy-Conscious Multisite Computation Offloading Techniques for Green Cloud Computing in order to investigate time-efficient scheduling on multisite, which is responsible for optimising energy, time, & cost at the optimum time. This strategy seeks to finish the application within the allotted amount of time while also consuming as little power as feasible from the connected devices. According to the findings of this research, it is clear that the explored technique is effective in obtaining high throughput (HT) while simultaneously minimising the execution time, which in turn enhances the data rate in Green Cloud Computing (GCC).

Revisiting IoT definitions: A framework towards comprehensive use

New technologies constantly change the paradigm of how businesses will be run in the future. The Internet of Things (IoT) enables new business opportunities for data-driven transformation in organisations. The emergence of the IoT concept has resulted in numerous definitions, with earlier references primarily focussed on the technological aspects. This has hindered the broader diffusion of the term IoT as, arguably, the definitions do not integrate other non-technological elements of IoT and focus more on business and service provisions. To resolve this, our research identifies the most significant building blocks required in designing an IoT system. This is accomplished through a methodological review of 122 definitions and their consolidation into a novel definitional framework. The definitional framework unifies the traditional technology focus of the earlier definitions and integrates additional elements that are likely to increase the adoption of a comprehensive definition to support the development of future business applications. Furthermore, the framework serves as a reference set for scholarly societies and standards organisations who, in the future, can be tasked with formulating a definition of IoT, as has been the case with the NIST definition of Cloud Computing, which was preceded by several academic studies on defining the term.

A Domain-Specific Language for the Document-Based Model-Driven Engineering of Business Applications

To facilitate the development of business applications, a domain-specific language (DSL), called DARC, is introduced in this paper. Business documents including the descriptions of the responsibilities, authorizations, and collaborations, are used as the first-class entities during model-driven engineering (MDE) with DARC. Hence the implementation of the business applications can be automatically achieved from the corresponding document models. The evaluation of using DARC DSL for the development of commercial business software was performed in an international sales, logistics, and service solution provider company. The results showed that the code for all business documents and more than 50% of the responsibility descriptions composing the business applications could be generated automatically by modeling with DARC. Finally, according to the users’ feedback, the assessment clearly revealed the adoption of DARC features in terms of the DSL quality characteristics, namely functional suitability, usability, reliability, maintainability, productivity, extensibility, compatibility, and expressiveness.

A Multiobjective Discrete Grey Wolf Optimization Approach for Transactional and QoS-driven Web Services Composition

ABSTRACT Web services facilitate reusability that allows cost-effective development of business applications using web services composition. Due to the proliferation of web services, different service providers are providing similar functionality web services. But these web services can have different values for QoS attributes and transactional properties. Thus, it is difficult to build a transactional and QoS optimal composite web service. Most of the existing works used the scalarization-based method for selecting optimal composite web service. In the scalarization-based method, the service user should have a priori knowledge of its preferences about the nonfunctional requirements of desired solutions. This paper proposes a Multiobjective Discrete Grey Wolf Optimization (MDGWO)-based approach for Transactional and QoS-driven Web Services Composition. The Pareto dominance concept is used to select optimal composite web service. Generational Distance (GD), Inverse Generational Distance (IGD), and Spread measures are used to evaluate the performance of the proposed approach. Experimental results indicate that the proposed approach performs well.

Rapid Requirements Elicitation of Enterprise Applications Based on Executable Mockups

Software development begins with the requirements. Misunderstandings with customers in this early phase of development result in wasted development time. This work investigates the possibility of using executable UI mockups in the initial phases of functional requirements elicitation during the development of business applications. Although there has been a lot of research in the field in recent years, we find that there is still a need to improve model-driven tool design in order to enable customer participation from the initial phases of requirement specifications based on working prototypes. These prototypes can directly be reused in the rest of the development process. To meet the goal, we have been developing an open-source solution called Kroki that enables rapid collaborative development. We conducted a series of 10 joint user sessions with domain experts from different domains and backgrounds, resulting in the prototype specifications ranging from 7 to 20 screen mockups accompanied with domain models, developed in two-hour time frames. In this paper, we present our tool design that contributes to rapid joint development, and the results from the user sessions.

Towards software reuse through an enterprise architecture-based software capability profile

ABSTRACT Most of today's software development projects depend on the usage of existing solutions to save time and development costs. We target in this research work the design of a software capability profile that provides a broader view of an organization’s software, along with an exploitation model in line with requirements engineering and enterprise architecture to fill the gap between the goals of the stakeholders and what can be delivered as a practical solution. Our contribution aims to improve the reuse of existing software, by upgrading these technical components to the level of end-user's requirements for accelerating future business application development

A Trade-Off Negotiation Strategy for Pareto-Optimal Service Composition with Additive QoS-constraints

QoS-based service composition enables the development of complex business applications. They are composed of distributed services characterized by QoS attributes representing non-functional characteristics, such as cost, execution time, and reliability. With the proliferation of services on the Internet, more candidates for each component service may be available with different QoS values. Hence, the ones satisfying QoS global constraints required for the application have to be selected. Automated negotiation is adopted to select component services in a dynamic market of services where provided QoS values may vary according to different market strategies. Nevertheless, when dealing with multiple QoS attributes, multiple service providers, and not shared information, it is difficult to guarantee the formal properties of the negotiation outcomes. In the present work, we propose a trade-off negotiation strategy that allows reaching a Pareto-optimal agreement, if it exists. The agreement consists of the QoS values of component services that are the ones selected to provide the complete application. The strategy exploits both the competition, that is due to multiple services providing the same functionality with different QoS values, and the cooperation among the providers of the different component services, that are necessary to meet the required end-to-end QoS constraints.

A Novel Hybrid Optimization-Based Approach for Efficient Development of Business-Applications in Cloud

The requests of the companies for the development and deployment of their business-applications in Cloud become more complex so that, sometimes, a one single service cannot carry out the target task on its own. Hence, a user-request is provided as a composite service. On another note, the number of available services is significantly increasing. Therefore, the authors would need to find the optimal cloud service-compositions that satisfy the quality of service values as well as user requirements. The methods proposed in literature for composing cloud services do not consider the composition and deployment constraints of candidate cloud services. This paper presents a novel optimization-based approach for building business-application in Cloud. The proposed approach combines the particle swarm optimization algorithm with some principles of ant colony optimization algorithm to deal with multiple QoS parameters, but also to satisfy the composition and deployment constraints of cloud services. The experimental results show the efficiency of the method for all tests instances.

Уровень ИТ подключается только для развития платформы путём классических подходов. The study solves the problem of circuit routing in ICs. We propose a multistage approach based on interconnection mesh reduction. It expands the chip interconnecting capability by introducing extra channels. The interconnection mesh reduction significantly accelerates the existing routing algorithms. The introduction of more channels makes it possible to reduce the routing problem in a complex interconnect space topology by removing the new routes from the extra (virtual) channels.

MODEL RAD DALAM PERANCANGAN FRONT END APLIKASI PAYMENT POINT ONLINE BANK (PPOB) BERBASIS ANDROID

The conventional purchase of credit by sending sms to the agent server is often has problem. The error was caused by different format of SMS for each server. This error has an impact on the high cost of using SMS. Another problem when the customer wants to check the electricity bill, the website provided by PLN is less attractive or have to come directly to the PLN payment counter. With these problems, an Android-based application was developed to provide convenience in purchasing credit without worrying about writing format errors and checking until payment of various types of bills becomes more efficient. Bill payments become more practical in one unit, so there is no need to go to different payment counters each month and not get stuck in a long queue that wash time. Development model of this PPOB application is RAD which consists of business modeling, data modeling, process modeling, application development and testing.

Web service discovery with incorporation of web services clustering

With the rapid growth and adoption of web-based technologies, more and more service providers offer various services on the web. This can facilitate the organizations to develop business applications using web services composition over the Internet according to their business requirements. The primary requirement for developing composite web service is to discover the most relevant web service for realizing each function of the required composite web service. Finding the most relevant web service is still a challenging task. In this paper, we propose web service discovery approach that incorporates web services clustering. Clustering technique combines latent Dirichlet allocation(LDA) and k-Medoids and reduces search space for web service discovery. Web service discovery uses a match-making algorithm that utilizes WordNet database and Hungarian method to compute the semantic similarity score for a web service based on the requested query. Experimental results show that the proposed approach performs better than LDA-based approach.

Should accountants care about blockchain?

AbstractThe use of blockchain technology has increased tremendously over the last decade. Blockchain continues to evolve and new features and capabilities are developed continuously. Although the use of the technology started in cryptocurrency (specifically, Bitcoin), it has expanded to other areas that can benefit from a shared, secure, ledger. This article investigates the potential impact of blockchain technology on the accounting profession. This article analyzes data security and privacy considerations, technology, adoption, and implementation considerations, and some considerations that relate specifically to accounting and auditing. We find that the unique needs of an accounting information system may not be a good match for blockchain as it currently exists. While we explain that blockchain may deliver many benefits, particularly in the areas of data reliability and the financial statement audit, we identify several factors, which raise significant questions about whether blockchain will ever be significantly integrated in the accounting function. Chief among those concerns is the scalability of the technology at an acceptable cost. While significant investment has and will be made for further development of blockchain business applications, it is our assessment that proponents of blockchain integration in accounting have not yet made the economic case for it. We also have significant concerns about whether blockchain technology can adequately address risks associated with data security and privacy. Addressing all these issues will be a minimum requirement for gaining widespread acceptance by firms and their accountants.

A Systematic information approaches are implemented with evidences of the security breaches of an organization to enhance the overall security

New Retail Business Analysis and Modeling: A Taobao Case Study

In recent years, many new business modes and strategies are constantly emerging in e-commerce. The new retail has been one of the most successful modes. Different from the traditional business modes, it is driven by information technology (big data, Internet of Things, artificial intelligence, etc.) and centered on consumer experience. Furthermore, it reconstructs the core elements in online and offline trade to form a new business mode. Thus, the existing business modeling approaches cannot be used to analyze and describe the new retail mode. In this article, we first analyze the business characteristics and processes in new retail and redefine the core elements in e-commerce, such as people, product, and place. EMB can decouple the business aspect and technical aspect of the business systems of e-commerce. So EMB can bridge the gap between business experts and application developers. In addition, we verify EMB by the electronic certificate business of Taobao and deeply analyze its reusability, applicability, and efficiency. Finally, to demonstrate the advantages of EMB, it is compared with some other existing methods in detail.

Multi-Media and Multi-Band Based Adaptation Layer Techniques for Underwater Sensor Networks

In the last few decades, underwater communication systems have been widely used for the development of navy, military, business, and safety applications, etc. However, in underwater communication systems, there are several challenging issues, such as limitations in bandwidth, propagation delay, 3D topology, media access control, routing, resource utilization, and power constraints. Underwater communication systems work under severe channel conditions such as ambient noise, frequency selectivity, multi-path and Doppler shifts. In order to collect and transmit the data in effective ways, multi-media/multi-band-based adaptation layer technology is proposed in this paper. The underwater communication scenario comprises of Unmanned Underwater Vehicles (UUVs), Surface gateways, sensor nodes, etc. The transmission of data starts from sensor nodes to surface gateway in a hierarchical manner through multiple channels. In order to provide strong and reliable communication underwater, the adaptation layer uses a multi-band/multi-media approach for transferring data. Hence, in this paper, existing techniques for splitting the band such as Orthogonal Frequency-Division Multiple Access (OFDMA), Frequency-Division Multiple Access (FDMA), or Orthogonal Frequency-Division Multiplexing (OFDM) are used for splitting the frequency band, and the medium selection mechanism is proposed to carry the signal through different media such as Acoustic, Visible Light Communication (VLC), and Infrared (IR) signals in underwater. For the channel selection mechanism, two phases are involved: 1. Finding the distance of near and far nodes using Manhattan method, and 2. Medium selection and data transferring algorithm for choosing different media.
