Analysis of different Sleeve Ferrite Cores Performance according to their Dimensions
2019
Sleeve ferrite core is an EMI suppressor widely used to reduce the conductive and radiated electromagnetic noise in cables. The interconnection of different electronic systems through cables is becoming more difficult due to the hard restrictions related to EMC compliance requirements. Thereby, the research of new solutions able to provide a great attenuation ratio in a wide frequency band is a challenge. This contribution focuses on analyzing and comparing the performance of a novel sleeve ferrite solution based on a nanocrystalline (NC) structure with several materials with different compositions. This component is able to provide a high initial permeability value at the same time that ma…
The Strategic Scorecards - An instrumentation of the strategic management accounting : Exploration of a concept, instrumentation and results from a f…
2002
I describe in this study a generic model of strategic management accounting instrumentation: the strategic scorecards. In order to build this generic model, I review in the existing literature the concepts of Strategic Control and Strategic Management Accounting (SMA). I present the characteristics of these concepts and analyse the reasons why they emerged. I show how the strategic scorecards are an instrumentation of the SMA in studying the most widely known and esteemed scorecards: the Balanced Scorecards (Kaplan & Norton, 1996) and Skandia's Navigator (Edvinsson & Malone, 1997). I then clarify the outlines for a generic model of strategic scorecard and disclose an "a priori" typology of …
Efficacy of the NaviTip FX irrigation needle in removing calcium hydroxide from root canal
2012
Objective: To evaluate the effectiveness of the NaviTip FX, brush-covered irrigation needle, in removing calcium hydroxide from the root canal. Study Design: Thirty single-rooted teeth were randomly divided into three groups: A - irrigation with a hypodermic needle inserted as far as possible without binding and activation with #30 K-type file; B - Irrigation with a hypodermic needle without activation; C - irrigation with NaviTip FX needle. Sodium hypoclorite 1% was used in irrigation. The root canals were examined trough scanning electron microscopy. Calcium hydroxide removal was recorded at 1, 5, and 10mm from the working length (WL) and the data were analysed using one-way ANOVA test (p…

Microfinance beyond self-employment: Evidence for firms in Bulgaria
2017
This paper provides new evidence on the impact of microfinance on job creation beyond self-employment. We examine wage-employment effects for a typical program in Eastern Europe with average loan sizes that are considerably above what has been studied so far. We apply propensity score matching extended by a difference-in-differences estimator to panel data from an individual-lending program to firms in Bulgaria. Our results indicate that microcredit has very positive effects on job creation. Participating firms have on average 2.5 (or 33 percent) more employees two years after receiving a microcredit than matched non-participants. This strong effect seems to be related to a certain loan siz…
Validation of the German version of the Kujala score in patients with patellofemoral instability : a prospective multi-centre study
2017
Introduction: The Kujala score is the most frequently used questionnaire for patellofemoral disorders like pain, instability or osteoarthritis. Unfortunately, we are not aware of a validated German version of the Kujala score. The aim of our study was the translation and linguistic validation of the Kujala score in German-speaking patients with patella instability and the assessment of its measurement characteristics. Materials and methods: The German Kujala score was developed in several steps of translation. In addition to healthy controls, the Kujala German was assessed in consecutive patients undergoing reconstruction of the medial patellofemoral ligament for recurrent patellar dislocat…
Exploration of Location-Based Services Adoption
2011
The purpose of this chapter is to explore aspects of user perceptions of their use of location-based services. As mobile technologies become more ubiquitous in the general population, it is reasonable to assume that individuals will consume services and software to enhance their aspirations and entertainment desires. This study begins by constructing a location-based service prototype simulation. It then conducts an experiment and analysis based on the Unified Theory of Acceptance and Use of Technology (UTAUT) model. A survey was developed to extract usage information from participants, followed by an analysis of the results using PLS. The analysis shows significant indicators that suggest …
Human capital evaluation in knowledge-based organizations based on big data analytics
2020
Abstract Starting from a Human Capital Analysis Model, this work introduces an original methodology for evaluating the performance of employees. The proposed architecture, particularly well suited to the special needs of knowledge-based organizations, is articulated into a framework able to manage cases where data is missing and an adaptive scoring algorithm takes into account seniority, performance, and performance evolution trends, allowing employee evaluation over longer periods. We developed a flexible software tool that gathers data from organizations in an automatic way – through adapted connectors – and generates abundant results on the measurement and distribution of employees’ perf…
Mobile commerce: core business technology and intelligent support
2005
Mobile commerce is an emerging field in its early stages, but there are a number of ideas of what is going to constitute the key success factors for the actors in the global m-commerce arena. This arena is already growing diversified with a number of application areas, which are growing in different directions and at different paces. We understand already that B2B, B2E, B2C and P2P will produce rather different types of applications, because the propositions for value-added products and services are quite different. This is probably one of the reasons why the hunt for the “mobile commerce killer applications” has been in vain so far.
IDCnet: Inclusive Design Curriculum Network – First Results
2004
This paper presents the preliminary results of the IDCnet Thematic Network in regard to the development of curriculum recommendations for Higher Education institutions in the area of ICT that include Design for All. These recommendations are based upon discussion with relevant actors in industry and academia to identify core knowledge sets and skills.
