Visualization of EDI messages
2003
Multi-organizational EDI message networks are complicated communication environments with various standards and technologies. The role of third party message exchange hubs has become more important and their tasks more difficult. Current development activities for supporting the utilization of XML in electronic commerce focuses on message standardization and specification of common business architectures, processes, and web practices. A need to visualize EDI messages in different contexts to human readers has received insufficient attention in ongoing activities. In this paper we discuss problems and approaches related to the visualization of EDI messages in XML format. An idea of a standar…
Economic Allocation in Life Cycle Assessment The State of the Art and Discussion of Examples
2012
Summary This article examines methods for analyzing allocation in life cycle assessment (LCA); it focuses on comparisons of economic allocation with other feasible alternatives. The International Organization for Standardization's (ISO) guideline 14044 indicates that economic allocation should only be used as a last resort, when other methods are not suitable. However, the LCA literature reports several examples of the use of economic allocation. This is due partly to its simplicity and partly to its ability to illustrate the properties of complex systems. Sometimes a price summarizes complex attributes of product or service quality that cannot be easily measured by physical criteria. On th…

Impact of COVID-19 on aquaculture sector in Malaysia: Findings from the first national survey
2021
Abstract Malaysian aquaculture sector consists of 391,000 t of cultivated organisms produced per year with an economic value for over USD 700 million as estimated in 2019. The COVID-19 pandemic caused a large global human pandemic and it is currently ongoing, affecting profoundly Malaysian aquaculture, which is vital for seafood provision and security assurance. Thus, to increase our understanding about how the pandemic affects aquaculture sectors is crucial to design possible management measures both at local and national level. To do it, we designed a survey, starting in May 2020, consisting of 25 online questions to collect information about the impact of COVID-19 on the aquaculture sect…
Processo, progetto e architettura
2019
[EN] The concept of systematization is an innovative approach to the project that introduces a system of order with a method that proceeds by aggregating repeatable parts and regulates the phases of the design process. These principles can be found in the theories and experiments that lead to contemporary architecture, such as seriality, standardization, modularity that transform the project into a process and determine a new aesthetic. The works of the Fran Silvestre Arquitectos studio represent interesting examples that highlight the clarity of the process that operates through seriality and the definition of configurations based on dimensional relationships rather than on scale factors (…
Motivazioni progettuali e verifica degli standard
2009
Il volume dà conto dei risultati di un complesso lavoro di studio e di ricerca derivante dall'incarico attribuito dal Comune di Palermo al Dipartimento di Storia e Progetto nell'Architettura e svolto dal gruppo di lavoro composto dai curatori. Il lavoro prende le mosse dall'elaborazione di uno "Studio di inquadramento territoriale per interventi di riqualificazione a Mondello" che costituisce il cardine tra la pianificazione sulla borgata di Mondello, vigente e di futura attuazione, e tutto l'insieme di ipotesi e aspettative che si è inteso promulgare attraverso la definizione di un bando per un Concorso Internazionale di idee e le riflessioni successive sugli esiti che da questo sono deriv…
Linee guida per la rilevazione dei dati del mercato immobiliare. Seconda parte.
2011
Le "Linee guida per la rilevazione dei dati del mercato immobiliare" propongono una serie di norme uniformi e condivisibili da parte dei valutatori e dei professionisti volte a fornire un comune strumento di rilevazione con il quale raccogliere, archiviare e scambiare i dati e le informazioni del mercato immobiliare. Il documento è diviso in due parti. La prima parte riporta i seguenti paragrafi: 1. Introduzione; 2. Mercato immobiliare; 3. Finalità della rilevazione; 4. Definizioni; 5. Scale di misura; 6. Elaborazione dei dati. La seconda parte riporta i paragrafi: 7. Scheda di rilevazione; 8. Fonti dei dati; 9. Informazioni utili; 10. Dati in entrata; 11. Dati non validi; 12. Norme di cond…
Revealing Transmit Diversity Mechanisms in Commercial IEEE 802.11 Cards
2008
Service differentiation in WLAN has been traditionally faced at the MAC layer. However, some PHY layer parameters, such as the transmission power, the antenna, and the modulation/coding scheme, have a deep impact on network performance. Since the criterion for selecting these parameters is left to the vendor specific implementations, the performance spread of most experimental results about 802.11 WLAN could be affected by vendor proprietary schemes. The focus of this paper is an experimental analysis of the undisclosed antenna diversity mechanisms employed by some widely used cards (namely, the Atheros and Intel based cards), and a thorough understanding of the optimization goals which gui…
An energy analysis of IEEE 802.15.6 scheduled access modes
2010
Body Area Networks (BANs) are an emerging area of wireless personal communications. The IEEE 802.15.6 working group aims to develop a communications standard optimised for low power devices operating on, in or around the human body. IEEE 802.15.6 specifically targets low power medical application areas. The IEEE 802.15.6 draft defines two main channel access modes; contention based and contention free. This paper examines the energy lifetime performance of contention free access and in particular of periodic scheduled allocations. This paper presents an overview of the IEEE 802.15.6 and an analytical model for estimating the device lifetime. The analysis determines the maximum device lifeti…
Standardisation of Artificial Intelligence: Making a “New World” Brave, with Support of Human Requirements in a Machine Intelligence Environment
2022
In line with previous industrial revolutions, standardisation must accompany the deployment of artificial intelligence systems that promise to revolutionise the way we live (home automation, autonomous vehicles, EdTech, etc.) and work (collaborative industrial robots, agricultural robots, inspection and maintenance robots, LegalTech, FinTech, etc.). The standards produced and promoted in Europe will be resolutely geared towards the protection of people and property, thus promoting the acceptability of these intelligent systems and the common interest. They will have to cover the requirements expected of AIs, but also the means and methods for assessing them. The new standards will have to c…
