This paper presents a bottom-up approach for a multiview measurement of statechart size, topological properties, and internal\r\nstructural complexity for understandability prediction and assurance purposes. It tackles the problem at different conceptual depths\r\nor equivalently at several abstraction levels. The main idea is to study and evaluate a statechart at different levels of granulation\r\ncorresponding to different conceptual depth levels or levels of details. The higher level corresponds to a flat process view diagram\r\n(depth = 0), the adequate upper depth limit is determined by the modelers according to the inherent complexity of the problem\r\nunder study and the level of detail required for the situation at hand (it corresponds to the all states view). For purposes of\r\nmeasurement, we proceed using bottom-up strategy starting with all state view diagram, identifying and measuring its deepest\r\ncomposite states constituent parts and then gradually collapsing them to obtain the next intermediate view (we decrement depth)\r\nwhile aggregating measures incrementally, until reaching the flat process view diagram. To this goal we first identify, define, and\r\nderive a relevant metrics suite useful to predict the level of understandability and other quality aspects of a statechart, and then we\r\npropose a fuzzy rule-based system prototype for understandability prediction, assurance, and for validation purposes....
Objectives: Study the initial expectations and the final realization of Information system (IS) with health\r\nprofessionals.\r\nMethods: Our study is done from two questionnaires includes 40 items (Q1 and Q2) based on modeling ethics.\r\nThis model is constructed using four universal ethical principles: autonomy-beneficenceââ?¬â??non-maleficence-justice we\r\nmeet with environmental parameters of the real: structural and technological-policy and procedural-organizational\r\nand regulatory-cultural and relationship. We interviewed 26 players consisting of 14 designers IS and 4 respectively\r\nresponsible for consulting firms, publishers of IS and hosting of medical data. A score ethics unit/100 were used to\r\nassess the ethical expectations (Q1) of the actors and the achievement ethic (Q2) for the SI.\r\nResults: The score ethical expectations unit (Q1: 78.7) of IS is higher than that of the realization (Q2: 63.7) of\r\nSI (p<0.001). The subscores ethical expectations belong in order of importance to ethical principles: beneficence\r\n(84.9)-autonomy (78.9)-non-maleficence (77.2)-justice (73.9). Subscores ethical achieving a mean SI (in order of\r\nimportance) the following ethical principles: autonomy (67.3)-beneficence (63.0)-non-maleficence (62.1)-justice (58\r\n6). The score ethical expectations unit (Q1) is higher than that of the realization (Q2) to all categories of protagonists\r\n(except the hosts of health data). Gives the same results if we study all the subscores principle by principle. Offer\r\nEthics (Q2) of the editors of SI is still below expectations ethical (Q1) of actors involved in contracting owner (MOA) of\r\nan IS healthy. Offer Ethics (Q2) of the hosts of health data is always higher ethical expectations of the actors involved\r\nin the entire MOA of an IS.\r\nConclusions: The application of our modeling ethics for study of the expectations and achieving a health IS\r\nresults in the coherent set according to the nature of the principles and stakeholders. This reflects a degree of accuracy\r\nof the assessment tool for health IS healthy. There is a double confrontation, on the one hand, between autonomy and\r\nbeneficence, and also between non-maleficence and justice, according to the expectations and the realization of IS\r\nwith the protagonists. By highlighting this model based on ethical principles and environmental parameters of reality,\r\nour work contribute to make the initial foundation of the architecture ethics of a health IS....
Characterising for contemporary systems is their dependence on constituent systems to provide information, functionality, and\r\nscalability.Moreover, as the tasks that systems performare evermore intimate and critical in their nature, reliability and correctness\r\nare great concerns. On thesematters, we outline amethodology for formal integration of systems.We claimthis formal approach to\r\nassist in managing the complexity and correctness, in preserving reliability and in respecting the independence of the constituent\r\nsystems. As a proof of concept, we integrate two in-house control systems specified independently in the Event-B language with the\r\nRodin Platform tool. Moreover, we show how to introduce a new functionality that is only possible due to the integration. Hence,\r\nwe formally construct a system of systems and provide the methods for hierarchical integration of those....
Portable Electronic Devices (PEDs) such as laptops, smart phones, tablets etc. have become an integral part\r\nof almost every higher education student�s learning toolbox. In this study, the faculty and student perspectives on\r\nthe effectiveness of the use of PEDs during classes are collected and compared using surveys done at Southern\r\nPolytechnic State University. Faculty openness and reservations, policies, student temptations and complaints are\r\ndiscussed. While the PEDs can be a source of distraction, they, if used carefully, can also provide an opportunity for\r\nengaging students....
Internet of Services (IoS) vision allows users to allocate and consume different web services on the fly without any prior knowledge\r\nregarding the chosen services. Such chosen services should automatically interact with one another in a transparent manner to\r\naccomplish the required users� goals. As services are chosen on the fly, service conversations are not necessarily compatible due\r\nto incompatibilities between services signatures and/or conversation protocols, creating obstacles for realizing the IoS vision. One\r\napproach for overcoming this problem is to use conversation adapters. However, such conversion adapters must be automatically\r\ncreated on the fly as chosen services are only known at run time. Existing approaches for automatic adapter generation are syntactic\r\nand very limited; hence they cannot be adopted in such dynamic environments. To overcome such limitation, this paper proposes a\r\nnovel approach for automatic adapter generation that uses conditional substitution semantics between application domain concepts\r\nand operations to automatically generate the adapter conversion functions. Such conditional substitution semantics are captured\r\nusing a concepts substitutability enhanced graph required to be part of application domain ontologies. Experiments results show\r\nthat the proposed approach provides more accurate conversation adaptation results when compared against existing syntactic\r\nadapter generation approaches....
