On the experimental validation of an improved five-parameter model for silicon photovoltaic modules

2012

Abstract This paper presents the experimental validation of a new five-parameter model capable of analytically describing the I–V characteristic of a silicon photovoltaic module for each generic condition of operative temperature and solar irradiance. The operating current calculated with the model was validated on the basis of a series of experimental measurements performed in the field on two commercial silicon photovoltaic panels connected to a set of nine constant values of the electrical load. In order to examine the panels working in almost steady-state conditions only the data-sets of the sunniest days from sunrise to sunset were used. Unfortunately the production spread of photovolt…

Superposing significant interaction rules (SSIR) method: a simple procedure for rapid ranking of congeneric compounds

2020

The Superposing Significant Interaction Rules (SSIR) method is revised and implemented. The method is a simple combinatorial procedure, which deals with in situ generated rules among a dichotomized congeneric molecular family, selecting the most probabilistically relevant ones. The mere counting of the number of relevant rules attached to new compounds generates a molecular ranking useful for database filtering, refinement and prediction. The algorithm only needs for a symbolic molecular representation and this allows for mining the database in a confidential manner. Third parties will not know the real compounds that are on the way to be worked out. The procedure is tested for a complete s…

Splitting the data cache: a survey

2000

Recent cache-memory research has focused on approaches that split the first-level data cache into two independent subcaches. The authors introduce a methodology for helping cache designers devise splitting schemes and survey a representative set of the published cache schemes.

Interaction through social media: Development and validation of a social network site self-efficacy scale (SNS-SES)

2023

Today, more than ever before, awareness of our ability to interact with others through and use social network sites (SNSs) is of fundamental importance, in light of the fact that we are connected to the Web 24 h a day, 7 days a week. Studies of social media in recent decades have shown that self-efficacy is one of the key variables affecting individual online behavior. The general aim of the studies presented here was to develop and validate a new self-report scale measuring self-efficacy in SNS use (an SNS self-efficacy scale, or SNS-SES). Across two studies, a total of 1295 Italian adolescents and adults (ages 15 to 89; M = 38.21, SD = 15.6) participated. The SNS-SES consists of 24 items …

Industrial Application and Evaluation of a Software Evolution Decision Model

A modest but practical software process modeling technique for software process improvement

2002

One of the main problems with software engineering is due to the difficulties in evaluating and improving our software processes, especially in the light of the fact that reuse depends on a process which supports it. Generally used approaches to the evaluation and improvement of software processes are based on the CMM, for example. In this paper we present a technique to improve software processes through modeling and evaluation. The presented technique is fairly easy to use, provides reasonably good results and requires only a fraction of resources required by CMM appraisals. Copyright © 2002 John Wiley & Sons, Ltd.

Use of Non-IT Testers in Software Development

2007

Because of a shortage of IT specialists, many companies which are not involved in software development business are forced to use employees who have minimal or no any knowledge about software development and IT as testers (let's call them non-IT testers). The author of this paper has used years of experience in working with such testers to provide a description of them, looking also at their most typical testing styles and the problems which occur for testers, their colleagues and bosses, and the overall software development processes. Non-IT testers often feel like second-class employees, because they are forced to work in an environment in which they do not have sufficient skills. This pa…

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…

Design Procedures for Soil-Lime Stabilization for Road and Railway Embankments. Part 2-Experimental Validation

2012

AbstractAs detailed in Part 1, the most common Italian Technical Specifications refer to different design methodologies for design of lime-soil mixtures, some being quite different from those internationally adopted. Therefore, it seemed appropriate to the Authors to compare these methodologies, via a wide experimental program.It is shown that the Italian methodology of the National Road Agency is different not only from those used in Italy, but also from the main international standards. The experimental results highlight that a revision of that methodology is needed in order to bring it into line with what is prescribed by the European standard.

Effect of the dissolution time into an acid hydrolytic solvent to tailor electrospun nanofibrous polycaprolactone scaffolds

2017

[EN] The hydrolysis of the polycaprolactone (PCL) as a function of the dissolution time in a formic/acetic acid mixture was considered as a method for tailoring the morphology of nanofibrous PCL scaffolds. Hence the aim of this research was to establish a correlation between the dissolution time of the polymer in the acid solvent with the physicochemical properties of the electrospun nanofibrous scaffolds and their further service life behaviour. The physico-chemical properties of the scaffolds were assessed in terms of fibre morphology molar mass and thermal behaviour. A reduction of the molar mass and the lamellar thickness as well as an increase of the crystallinity degree were observed …
