Use of ICT Teaching-Learning Methods make School Math Blossom

2012

Abstract Our society often talks that their kids at school are taught using old educational methods. It is boring for kids and they lose interest in learning. New generation of kids are different – more provocative, intuitive, sensitive, mental, in some cases more aggressive than previous generations. That is what parents and teachers now see. Therefore the aims of nowadays education demand to choose educational methods promoting active process of cognition that develop skills of learning, creative use of knowledge, skills of self-assessment, cooperation, indulgence to different points of view. Interactive educational methods help to realize those tasks and provide cooperation among teacher…

Waveguide filters for satellites

2007

This article describes the historical evolution, and its theoretical and technological features of waveguide filters. All-metal waveguide filters have been widely used in satellite payloads since the advent of the first space communication systems four decades ago. In this period, such technology has been continuously evolving due to the increasing requirements demanded to these components. Special attention has also been paid to present the most recent advances in the development of CAD tools for satellite filters, which are based on full-wave electromagnetic analysis methods. Finally, the compact solutions for the input and output stages of satellite payloads are focused on, thus consider…

High Level Planning of Reconfigurable Enterprises: a Game Theoretic Approach

2006

Reconfigurable Enterprises (REs) represent production networks made of different and geographically dispersed plants that, in case of unpredictable market changes, can be reconfigured in order to gather a specific production objective. However, REs effectiveness and efficiency depend on the extent to which global performance is obtained. Basically two approaches are available to reach coordination: centralised or decentralised planning tools. In this paper, the authors propose a novel cooperative game theoretical approach for distributed production planning at high level of a RE; the proposed approach has been benchmarked in front of both a distributed one, based on negotiation, and a centr…

A comprehensive analysis of electric energy consumption of single point incremental forming processes

2014

Abstract Production processes, as used for discrete part manufacturing, are responsible for a substantial part of the environmental impact of products, but are still poorly documented in terms of environmental impact. The present paper proposes a comprehensive energetic analysis of Single Point Incremental Forming Processes (SPIF). The three most commonly used machine tool architectures able to perform SPIF operations have been taken into account: a CNC milling machine, a six-axes robot as well as the dedicated AMINO machine tool were analyzed from an electrical energy consumption point of view. For all the setups, a working cycle time study and power study were performed. Moreover the cont…

The Environmental Issue in Sicily

2014

In Italy, despite the number of protected natural areas and the abundance of scientific research upon the landscape, the level of control of human pressure on the environmental system is still seriously inadequate. Among the main factors is the disconnection between urban/regional and sectorial planning, in the frame of the detachment of the nature conservation policies from the landscape and territorial policies, which is the focus of the present research. The regional situation is rendered even more serious by the lack of an up-to-date planning law (the Sicilian planning law was passed in 1978), the poor diffusion of territorial and vast area planning (the Regional Master Plan has never b…

The Role of Physicians' Digital Tools in Pharmacological Management of Type 2 Diabetes Mellitus

2022

Background and Objectives: The constantly increasing prevalence of type 2 diabetes mellitus (T2DM) and the advent of new treatment options have made management of T2DM patients more demanding. We aimed to (a) estimate the familiarity of general practitioners with novel T2DM treatment options, (b) determine whether a digital tool can aid in their treatment decisions and (c) demonstrate that an evidence-based digital clinical support tool can be made using an existing digital platform. Materials and methods: This proof-of-concept study consisted of two parts: We first conducted a simple online survey among general practitioners of three European countries to estimate their familiarity with no…

Prospective de la relation formation-emploi dans un territoire : Richesse des outils, cohérence de l'analyse et incohérence dans l'action

2005

05111; Cette contribution porte sur la prospective en matière de relation formation-emploi tant au niveau régional qu'européen : où en sommes-nous de la capacité de mobilisation de l'information économique et sociale ? Jusqu'à quel point le partage de l'information entre acteurs régionaux est-il possible ? Quel est le rôle des informations dans l'aide à la décision ? Quel est le rapport de la connaissance à l'action ? La réflexion s'appuie sur une comparaison des démarches prospectives mises en oeuvre dans le secteur de l'hôtellerie-restauration dans certaines régions de trois pays européens : la France, la Tchéquie et la Slovénie. Elle souligne la richesse de l'outil statistique existant p…

Negotiations with a risk assessment tool: Standardized decision-making in the United States and the deprofessionalization thesis

2017

AbstractThis article focuses on the challenges of decision-making in child protection. Comparative studies show that standardized risk assessment tools predict future maltreatment more accurately than interpretative assessment. Despite a long tradition of research on statistical decision-making, few studies deal with how such instruments are used and integrated into professional decision-making practice, and – from a transnational perspective – how specific national regulations influence such instruments and decision-making at street level. The article discusses concerns about the fact that such classification systems might have a negative impact on professional discretion. Based on a mater…

Wear modelling in mild steel orthogonal cutting when using uncoated carbide tools

2007

Abstract Wear prediction in machining has been recently studied by FEM although the use of numerical methods for such applications is still a very challenging research issue. In fact, wear phenomenon involves many aspects related to process mechanics which require a very accurate modelling. In other words, only a very punctual code set-up can help the researchers in order to obtain consistent results in FE analysis. The high relative velocity between chip and tool requires effective material models as well as friction modelling at the interface. Moreover the prediction of temperature distribution is another critical task; in the paper some different procedures are discussed. Subsequently a …
