A metrics suite for evaluating agent-oriented architectures
2010
The Multi-agent Systems (MASs) paradigm continues to consolidate itself as a new branch of software engineering. Traditional software engineering strongly recommends to apply metrics in software developments. However, several research groups of experts in agent-oriented software engineering agree that classical software metrics and object-oriented metrics cannot directly measure the quality of MAS architectures. For this reason, this work proposes a suite of metrics to measure certain quality attributes of MAS architectures, considering agents and their organization. Most of these metrics are inspired by object-oriented metrics but they are adapted to agent-oriented concepts. Proposed metri…
Graph grammar engineering: A software specification method
1987
Graphs as conceptual data models are accepted and used in a wide range of different problem areas. Giving some examples we outline common aspects for modeling complex structures by graphs. We present a formal frame-work based on graph grammars to specify graph classes and the corresponding graph manipulations. We show that such a specification can be written in a systematic, engineering-like manner. This is achieved by an extension of the known programmed, attributed graph grammars. Node-set operators are introduced to facilitate graph queries. Concepts like abstraction, decomposition, refinement, parameterization, and integration have been adopted from software engineering to yield a compr…
Software Requirements for Ubiquitous Ad Hoc Mobile Networks: An Example of a Bluetooth Application
2009
In contrast with the simple and elegant concept of global computing, also called ubiquitous computing - where daily life objects get now computing capacity and interact among them to provide a wide range of services to users - a major difficulty is arising with the software engineering process to develop applications for these devices. This article discusses the additional parameters that should be taken into account when designing and developing software for ubiquitous devices in ad-hoc networks. In these networks the mobility of the devices could increase the complexity of the requirements to be considered. As a case study, we present a Bluetooth application that has been developed to ful…
The Influence of Requirements in Software Model Development in an Industrial Environment
2017
Textual description of requirements is a specification technique that is widely used in industry, where time is key for success. How requirements are specified textually greatly depends on human factors. In order to study how requirements processing is affected by the level of detail in textual descriptions, this paper compares enriched textual requirements specifications with non-enriched ones. To do this, we have conducted an experiment in industry with 19 engineers of CAF (Construcciones y Auxiliares de Ferrocarril), which is a supplier of railway solutions. The experiment is a crossover design that analyzes efficiency, effectiveness, and perceived difficulty starting from a written spec…
Towards Integrated Computer Aided Systems and Software Engineering Tool for Information Systems Design
1996
The paper starts with a brief overview of the current situation in the world of CASE tools for information systems. Then there follows the outline of the basic ideas and principles of integrated CASE tool GRADE. The most outstanding characteristics of GRADE are that the tool is based on a unified specification language GRAPES and that it supports all information system development phases including analysis, requirements specification, design and implementation.
A feasibility analysis on the use of ultrasonic multihop communications for E-health applications
2017
Rise in population aging as well as diffusion of chronic diseases and health consciousness require constant monitoring of health conditions but also lead to increasing costs for the governments. Body Area Networks represent the next frontier in health care and are envisaged as the natural choice to provide detailed and updated information on health status to prevent health risks and diseases. However if, on the one hand, a large research effort has been devoted so far to the investigation of BAN communications on and around the body, on the other hand intra-BAN communications are still a scarcely explored area because of the difficulties and risks in successfully propagating signals inside …
Benefits of Software Renting in Cloud Business
2012
In the new era of computing, software can be sold and delivered as a cloud service, and software renting has become a strategic tool to compete in the market. In this multi-case study, software renting was found to help the case firms to (i) differentiate themselves from competitors; (ii) increase their competitive advantage by making the software available for a larger customer group, and (iii) decrease the price of software by using centralized software delivery and maintenance. peerReviewed
What makes a (ro)bot smart? : examining the antecedents of perceived intelligence in the context of using physical robots, software robots, and chatb…
2022
In recent years, the acceptance and use of intelligent robots and other kinds of intelligent systems have begun to gain more and more attention also in information systems research. Here, many studies have found the perceived intelligence of robots to act as one critical antecedent for their acceptance and use, but few studies have focused on the antecedents of perceived intelligence itself. In this study, we aimed to address this gap in prior research by examining the effects of individual intelligence dimensions on the overall intelligence perception of robots in the work context. In addition, we also examined the potential differences in these effects as well as in the individual intelli…
Laboratorio di Statistica Economica con R
2009
Questo libro costituisce materiale di supporto ed integrazione alle lezioni di LABORATORIO DI STATISTICA ECONOMICA svolte nell’ambito del Corso di Laurea in STATISTICA ED INFORMATICA PER LA GESTIONE E L’ANALISI DEI DATI (SIGAD) della Facoltà di Economia dell’Università degli Studi di Palermo. La ragione di questo progetto editoriale è nell’assenza di un testo dedicato da offrire agli studenti. Ciò, naturalmente, non esclude che il volume possa risultare utile anche in contesti didattici più generali quale supporto per un percorso applicato di alcuni classici temi eco- nomici ben aldilà dello specifico corso per il quale è stato progettato. Nell’offerta formativa dell’Ateneo di Palermo, il L…
The Comparison of Software Reliability Assessment Models
2015
Abstract The reliability of the software represents one of the most important attributes of software quality, and the estimation of the reliability of the software is a problem hard to solve with accuracy. Nevertheless, in order to manage the quality of the software and of the standard practices in an organization, it is important to achieve an estimation of the reliability as accurate as possible. In the present work there are described the principles and techniques which underlie the estimation of the reliability of the software, starting from the definition of the concepts which express the attributes of software quality. It is taken into account the issue of the estimation of a software…
