    The vision of the Internet of Things (IoT) has sparked considerable efforts in research and development over the past decade.Much of these efforts were driven by applications of RFID technology for monitoring the flow of goods and prominent earlyadopters such as Wal-Mart and Metro Group. Also, the global standards organization GS1 provided a number of wellrecognized specifications that are tailored to monitor objects across organizations.Development of the IoT has certainly benefited from the strong demand for monitoring goods in business applications.However, the dominance of these application scenarios and corresponding standards comes at the risk of neglectingrequirements from other domains. In this paper, we review the focus of existing works. Our contribution is twofold. (1) Usinga systematic literature review, we analyze existing research contributions and identify underrepresented areas. (2) We discussselected approaches in detail and highlight open issues in the covered functionality. The aim of our work is to raise awarenessfor open potentials in the IoT service domain and to direct future research and developments

    Landfills generate leachate that contains elevated concentration of contaminants and is hazardous to human health and the ecosystem. In this study, the mixture of granular activated carbon and cockle shells was investigated for remediation of COD and ammonia from stabilized landfill leachate. All adsorbent media were sieved to a particle size between 2.00 and 3.35 mm. The optimum mixing ratio, shaking speed, shaking time, pH, and dosage were determined. Characterization results show that the leachate had a high concentration of COD (1763 mg/L), ammonia nitrogen (573 mg/L), and BOD5/COD ratio (0.09). The optimum mixing ratio of granular activated carbon and cockle shells was 20:20, shaking speed 150 rpm, pH level 6, shaking time 120 min, and dosage 32 g. The adsorption isotherm analysis reveals that the Langmuir isotherm yielded the best fit to experimental data as compared with the Freundlich isotherm. The media produce encouraging results and can be used as a good and economical adsorbent

    Advances in Supply Chain Management Decision Support Systems: Potential for Improving Decision Support Catalysed by Semantic Interoperability between Systems

    Globalization has catapulted ‘cycle time’ as a key indicator of operational efficiency [1] in processes such as supply chain management (SCM). Systems automation holds the promise to augment the ability of supply chain operations or supply networks to rapidly adapt to changes, with minimal human intervention, under ideal conditions. Business communities are emerging as loose federations or organization of networks that may evolve to act as infomediaries in global SCM. These changes, although sluggish, are likely to impact process knowledge and in turn may be stimulated or inhibited by the availability or lack of process interoperability, respectively. The latter will determine operational efficiencies of supply chains. Currently “community of systems” or organization of networks (aligned by industry or business focus) contribute minimally in SCM decisions because true collaboration remains elusive. Convergence and maturity of multiple advances offers the potential for a paradigm shift in interoperability. It may evolve hand-in-hand with [a] the gradual adoption of the semantic web [2] with concomitant development of ontological frameworks, [b] increase in use of multi-agent systems and [c] advent of ubiquitous computing enabling near real-time access to identification of objects and analytics [4]. This paper examines some of these complex trends and related technologies. Irrespective of the characteristics of information systems, the development of various industry-contributed ontologies for knowledge and decision layers, may spur self-organizing networks of business communities and systems to increase their ability to sense and respond, more profitably, through better enterprise and extraprise exchange. In order to transform this vision into reality, systems automation must be weaned from the syntactic web and integrated with the organic growth of the semantic web. Understanding of process semantics and incorporation of intelligent agents with access to ubiquitous near real-time data “bus” are pillars for “intelligent” evolution of decision support systems. Software as infrastructure may integrate plethora of agent colonies through improved architectures (such as, service oriented architecture or SOA) and business communities aligned by industry or service focus may emerge as hubs of such agent empires. However, the feasibility of the path from exciting “pilots” in specific areas toward an informed convergence of systemic real-world implementation remains unclear and fraught with hurdles related to gaps in knowledge transfer from experts in academia to real-world practitioners. The value of interoperability between systems that may catalyse real-time intelligent decision support is further compromised by the lack of clarity of approach and tools. The latter offers significant opportunities for development of tools that may segue to innovative solutions approach. A critical mass of such solutions may spawn the necessary systems architecture for intelligent interoperability, essential for sustainable profitability and productivity in an intensely competitive global economy. This paper addresses some of these issues, tools and solutions that may have broad applicability in several operations including the management of adaptive supply-demand networks [7]

    In this paper the development and architecture of the SocIoTal platform is presented. SocIoTal is a European FP7 project which aims to create a socially-aware citizen-centric Internet of Things infrastructure. The aim of the project is to put trust, user-control and transparency at the heart of the system in order to gain the confidence of everyday users and developers. By providing adequate tools and mechanisms that simplify complexity and lower the barriers of entry, it will encourage citizen participation in the Internet of Things. This adds a novel and rich dimension to the emerging IoT ecosystem, providing a wealth of opportunities for the creation of new services and applications. These services and applications will be able to address the needs of society therefore improving the quality of life in cities and communities. In addition to technological innovation, the SocIoTal project sought to innovate the way in which users and developers interact and shape the direction of the project. The project worked on new formats in obtaining data, information and knowledge. The first step consisted of gaining input, feedback and information on IoT as a reality in business. This led to a validated iterative methodology which formed part of the SocIoTal toolkit.This work was supported by the SocIoTal project under grant agreement No 609112

    Enterprise resource planning (ERP) systems participate in interoperability projects and this participation sometimes leads to new proposals for the ERP field. The aim of this paper is to identify the role that interoperability plays in the evolution of ERP systems. To go about this, ERP systems have been first identified within interoperability frameworks. Second, the initiatives in the ERP field driven by interoperability requirements have been identified from two perspectives: technological and business.The ERP field is evolving from classical ERP as information system integrators to a new generation of fully interoperable ERP. Interoperability is changing the way of running business, and ERP systems are changing to adapt to the current stream of interoperability

    Blockchain and Internet of Things in smart cities and drug supply management: Open issues, opportunities, and future directions

    Get PDF
    Blockchain-based drug supply management (DSM) requires powerful security and privacy procedures for high-level authentication, interoperability, and medical record sharing. Researchers have shown a surprising interest in Internet of Things (IoT)-based smart cities in recent years. By providing a variety of intelligent applications, such as intelligent transportation, industry 4.0, and smart financing, smart cities (SC) can improve the quality of life for their residents. Blockchain technology (BCT) can allow SC to offer a higher standard of security by keeping track of transactions in an immutable, secure, decentralized, and transparent distributed ledger. The goal of this study is to systematically explore the current state of research surrounding cutting-edge technologies, particularly the deployment of BCT and the IoT in DSM and SC. In this study, the defined keywords “blockchain”, “IoT”, drug supply management”, “healthcare”, and “smart cities” as well as their variations were used to conduct a systematic search of all relevant research articles that were collected from several databases such as Science Direct, JStor, Taylor & Francis, Sage, Emerald insight, IEEE, INFORMS, MDPI, ACM, Web of Science, and Google Scholar. The final collection of papers on the use of BCT and IoT in DSM and SC is organized into three categories. The first category contains articles about the development and design of DSM and SC applications that incorporate BCT and IoT, such as new architecture, system designs, frameworks, models, and algorithms. Studies that investigated the use of BCT and IoT in the DSM and SC make up the second category of research. The third category is comprised of review articles regarding the incorporation of BCT and IoT into DSM and SC-based applications. Furthermore, this paper identifies various motives for using BCT and IoT in DSM and SC, as well as open problems and makes recommendations. The current study contributes to the existing body of knowledge by offering a complete review of potential alternatives and finding areas where further research is needed. As a consequence of this, researchers are presented with intriguing potential to further create decentralized DSM and SC apps as a result of a comprehensive discussion of the relevance of BCT and its implementation.© 2023 The Author(s).

    Can Convergence of Innovation Catalyse Economic Growth?

    Get PDF
    Big ideas offer big dividends but have stormy beginnings. Even worse is when people cannot visualise the future because their imagination is bent out of focus by short-term ROI or resistance to change status quo! Systemic vision requires individuals who can visualize future issues with dynamic and analytical convergence which balances the odds of probabilistic decision making in a generally uncertain world. It is such ‘inclusive' and out-of-the-box thinking that is uncommon because institutions still offer prizes for depth of expertise, almost exclusively. Erudite scholars such as Murray Gell-Mann and Nicholas Negroponte, continue to comment on the need for individuals with ‘horizontal’ understanding. But, academic status quo and paucity of such enlightened views are discouraging individuals to pursue a broad spectrum of ‘horizontal’ understanding. In "Darwin's Middle Road" that Stephen Jay Gould wrote for his monthly column in the Natural History magazine, Gould once said, "if genius has any common denominator, I would propose breadth of interest and the ability to construct fruitful analogies between fields."This article is about convergence and why not. How about a ride to space in an elevator? Why not? A single nanotube could stretch from earth to the stratosphere and be able to support its own weight. This fact spurred NASA to review ideas proposed by Konstantin Tsiolkovsky (1895) a Russian visionary and Arthur C. Clarke in The Fountains of Paradise (1978). The idea is to build an elevator (lift) that will travel 60,000 miles from the earth’s surface into space carrying cargo and humans. It is predicted that the ‘space elevator’ will lower the cost of positioning a satellite in space from 10,000to10,000 to 100 per pound.

Bradley Edwards’ proposal calls for a single nanotube about 75 cm wide and thinner than a piece of paper that will stretch 60,000 miles from the surface of the earth or the ocean floor (The Space Elevator by Bradley Edwards, 2002). A 3-day NASA conference in Santa Fe, New Mexico (September 2003) drew 60 scientists and engineers working on the concept. The outcome of the meeting: “it is plausible.” (Gentry Lee, Chief Engineer, JPL, Cal Tech). The ‘space elevator’ apparatus would lift up to 13 tons of cargo in a week to reach the geosynchronous orbit (22,300 miles). The necessary underlying technologies exist except the carbon nanotube material (ribbon). The estimated cost to build the first space elevator may be 6 to 12billion.Subsequentelevatorsmaycost12 billion. Subsequent elevators may cost 2 billion. The estimated cost of building and operating the international Space Station is expected to exceed $100 billion. Those who are teenagers today, may wish to book a suite in that elevator to space, to celebrate their 50th marriage anniversary!MIT Forum for Supply Chain Innovation http://supplychain.mit.edu/shoume

    Adopting new information and communication technology (ICT) as a solution to achieve food security becomes more urgent than before, particularly with the demographical explosion. In this survey, we analyze the literature in the last decade to examine the existing fog/edge computing architectures adapted for the smart farming domain and identify the most relevant challenges resulting from the integration of IoT and fog/edge computing platforms. On the other hand, we describe the status of Blockchain usage in intelligent farming as well as the most challenges this promising topic is facing. The relevant recommendations and researches needed in Blockchain topic to enhance intelligent farming sustainability are also highlighted. It is found through the examination that the adoption of ICT in the various farming processes helps to increase productivity with low efforts and costs. Several challenges are faced when implementing such solutions, they are mainly related to the technological development, energy consumption, and the complexity of the environments where the solutions are implemented. Despite these constraints, it is certain that shortly several farming businesses will heavily invest to introduce more intelligence into their management methods. Furthermore, the use of sophisticated deep learning and Blockchain algorithms may contribute to the resolution of many recent farming issues
