A new algorithm for the kinetic data analysis
2000
Abstract In this paper, a new algorithm for the kinetic data analysis is presented. The main objective of the algorithm is to retrieve the maximum information concerned with a multi-response complex chemical system evolving in time, in order to retrieve the rate constants (calibration problem) or the initial concentration of species. As a difference with other data treatments found in the literature, the algorithm is able to estimate the uniqueness and reliability of the calculated rate constants. This task is carried out by analyzing of the principal components of the sensitivity coefficients with regard to the rate constants. The analysis allows understanding whether the located stationar…
Requirements elicitation methods based on interviews in comparison: A family of experiments
2020
Abstract Context There are several methods to elicit requirements through interviews between an end-user and a team of software developers. The choice of the best method in this context is usually on subjective developers’ preferences instead of objective reasons. There is a lack of empirical evaluations of methods to elicit requirements that help developers to choose the most suitable one. Objective This paper designs and conducts a family of experiments to compare three methods to elicit requirements: Unstructured Interviews, where there is no specific protocol or artifacts; Joint Application Design (JAD), where each member of the development team has a specific role; Paper Prototyping, w…
A Methodological Approach for Developing and Validating a Parsimonious and Robust Measurement Tool: The Academic E-Service Quality (ACEQUAL) Model
2021
Nowadays, in the higher education sector, the quality measurement process of education-related services is assuming a crucial role to support focused and targeted improvement activities deeply centered on students’ needs/necessities. These are considered crucial factors for dealing with the current academic competitive context. Therefore, the quality measurement process has to be precise and accurate, namely the measurement model on which it is based has to be parsimonious and robust. The present work proposes an effective and easy-to-use methodological approach suitable for supporting the structuring of a measurement tool. Its effectiveness is shown with reference to the academic e-service…
Putting documents into their work context in document analysis
2000
In trying to achieve document standardization the goal is to find more effective, consistent, and standardized ways to utilize information technology. The specification and implementation of document standards may take several years requiring a profound analysis and understanding of document management practices. Document standardization does not concern documents only: it concerns workers, their work, business partners, and future systems as well. In this paper we discuss two ways of describing the work context of documents: process modelling and life cycle modelling. In process modelling, documents are regarded as resources produced and used in inter- or intra-organizational business proc…
Study of the imaging conditions and processing for the aspect control of specular surfaces
2001
A vision system capable of imaging and detecting defects on reflective nonplanar surfaces in the production line at a high cadence is presented in this paper. Defects are typically dust located under the metallic layer of packaging products used in cosmetic industries. To realize this processing, structured lighting which reveals the defects in the image is proposed. Defects appear clearly in the images like a set of brilliant pixels in dark zones. The signature of the defect is then obtained. The size of this signature does not depend linearly on the size of the defect. It is a function of the observation angle. In order to realize a precise and robust process, the necessity of acquiring s…
Using QSPS in Developing and Realization of a Production Line in Automotive Industry
2010
<p>Using the QSPS (Quality System for the production software) for industrial projects and not only therefore, has led to accurate running of the production line from beginning of the SOP (Start of Production). This paper presents the application way of the QSPS at one of the strongest European automotive company. By using of this system several significant costs savings and quality improvement can be observed.<br /> The content of this paper will show step by step how to use QSPS for the integration of a production line in the traceability system from a big company in automotive industry.<br /> The production line involved contains 56 production equipments, which have to …
Teachers Attitudes toward Autism Spectrum Disorder: A Systematic Review
2022
(1) Teachers’ attitudes toward the inclusion of students with autism spectrum disorder (ASD) in mainstream schools influence daily educational practices. Depending on whether these attitudes are favorable or not, inclusive education could be fully or partially reached. This systematic review aims to analyze teachers’ attitudes toward ASD and to determine the variables that moderate them. (2) We conducted a systematic review in WoS, Scopus, and PsycINFO databases, obtaining an amount of 16 studies included in this review. (3) The results revealed inconclusive levels in teachers’ attitudes: Some of the teachers reported positive attitudes, some neutral, and some negative. (4) Among the variab…
The Use of Rule-Based and QSPR Approaches in ADME Profiling: A Case Study on Caco-2 Permeability.
2013
During the early ADME profiling the development of simple, interpretable and reliable in silico tools is very important. In this study, rule-based and QSPR approaches were investigated using a large Caco-2 permeability database. Three permeability classes were determined: high (H), moderate (M) and low (L). The main physicochemical properties related with permeability were ranked as follows: Polar Surface Area (PSA)>Lipophilicity (logP/logD)>Molecular Weight (MW)>number of Hydrogen Bond donors and acceptors>Ionization State>number of Rotatable Bonds>number of Rings. The best rule, based on the combination of PSA-MW-logD (3PRule), was able to identify the H, M and L classes with accuracy of …
The RedTube copyright infringement affair in Germany: shame on who?
2015
Recently, tens of thousands of German Internet users were confronted with copyright infringement claims for allegedly watching porn clips on the streaming platform RedTube.com. The alleged copyright infringers received ‘Abmahnung’ cease and desist letters that gave them an opportunity to settle copyright infringements out of court by paying rights-holders €250 in compensation. While in cases relating to peer-to-peer file-sharing, the IP address of a peer can easily be identified,1 the RedTube case raises the question how consumers of a stream could be identified. In addition, it raises the question of whether the consumption of a stream is illegal under German law. Assuming that this is not…
Cellular Models and Assays to Study NLRP3 Inflammasome Biology
2020
The NLRP3 inflammasome is a multi-protein complex that initiates innate immunity responses when exposed to a wide range of stimuli, including pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs). Inflammasome activation leads to the release of the pro-inflammatory cytokines interleukin (IL)-1β and IL-18 and to pyroptotic cell death. Over-activation of NLRP3 inflammasome has been associated with several chronic inflammatory diseases. A deep knowledge of NLRP3 inflammasome biology is required to better exploit its potential as therapeutic target and for the development of new selective drugs. To this purpose, in the past few years, several tools have…
