In this paper, a new algebraic approach to the on-line signal derivatives estimation is proposed. The proposed approach is based on the conversion of the truncated Taylor series expansion to the set of linearly independent equations regarding the signal derivatives. The nonhomogeneous parts of the obtained set of equations are convolution integrals, which can be transformed to the stable linear state-space filter realization. The proposed algebraic estimator provides stable convergence without the need for periodic re-initialization, as in the case of the conventional algebraic estimators. In contrast to the Taylor series-based tracking differentiators, the proposed estimator also provides an estimation of the arbitrary number of the higher-order signal derivatives. In addition, the tuning of the estimator parameters does not depends on the filter dimension. The efficiency of the proposed estimator is illustrated by the simulation examples and experimental results related to the monitoring of the surgical drilling process. 相似文献

An increasing prevalence of gestational diabetes has become a very challenging task in prenatal care worldwide. International Association of Diabetes and Pregnancy Study Groups (IADPSG) has recently issued recommendations on the diagnosis and classification of hyperglycaemia in pregnancy. These recommendations, the first to provide harmonised, evidence-based criteria for the diagnosis and classification of diabetes in pregnancy, are currently being discussed and accepted worldwide by the relevant authorities. As the acceptance of the proposed criteria has major implications for both clinical and laboratory settings, a concerted action towards necessary changes in practice has to be carefully planned and adjusted to national health-care specificities.IADPSG criteria have been strongly advocated by the Croatian Perinatology Society, resulting in a new strategy for the detection and diagnosis of hyperglycaemic disorders in pregnancy.To address the respective laboratory requirements, in April 2012, the Croatian Chamber of Medical Biochemists appointed a Working Group to provide a standardised procedure for the diagnosis of gestational diabetes, applicable to all laboratories involved in prenatal care, in both primary and specialised health-care facilities.In this paper we discuss key laboratory-related issues regarding succesful implementation of the IADPSG criteria in Croatia. 相似文献

The Lawson Classroom Test of Scientific Reasoning (LCTSR) was used to gauge the relative effectiveness of three different methods of pedagogy, Reading, Presenting, and Questioning (RPQ), Experimenting and Discussion (ED), and Traditional Methods (TM), on increasing students' level of scientific thinking. The data of a one-semester-long senior high-school project indicate that, for the LCTSR: (a) the RPQ group (n?=?91) achieved effect-sizes d?=?0.30 and (b) the ED group (n = 85) attained effect-sizes d?=?0.64. These methods have shown that the Piagetian and Vygotskian visions on learning and teaching can go hand in hand and as such achieve respectable results. To do so, it is important to challenge the students and thus encourage the shift towards higher levels of reasoning. This aim is facilitated through class management which recognizes the importance of collaborative learning. Carrying out Vygotsky's original intention to use teaching to promote cognitive development as well as subject concepts, this research has shown that it is better to have students experience cognitive conflict from directly observed experiments than by reflecting on reported experience from popularization papers or writings found on the internet. 相似文献

The recent discussion between Lewis and Linn (Journal of Research in Science Teaching, 33, 335–337, 1996) and Pushkin (Journal of Research in Science Teaching, 33, 223–224, 1996) concerning the definitions of terms relating to heat raises the broader issue of the nature of scientific terms and their role in instruction. We illustrate that in just two significant examples (heat and electricity) it is easy to illustrate from the literature that there is not agreement as to the meaning of the terms among scientists and that between texts, even within texts, terms are used in such inconsistent ways that there is no logical way to sort out the meanings of the terms. Hence, if “standard interpretations of scientific knowledge to be taught” do not actually exist, then how can the teaching of standard interpretations of scientific knowledge be established as a goal to be accomplished? © 1997 John Wiley & Sons, Inc.

The main aim of the present study was to examine the quality of religious education in Croatian primary schools when assessed from teachers’ perspective. Religious education teachers (N?=?226) rated the impact of certain factors on the existing quality of religious education in primary schools and expressed their expectations about the future status of this aspect of education. In addition, teachers rated different sources of their professional satisfaction as religious education teachers. We identified understandable latent dimensions of teachers’ opinions, expectations and satisfaction where retained dimensions are modestly interrelated. The conducted regression analyses suggest that teachers with different professional status-related personal attributes are fairly uniform in their views, expectations and satisfactions. An interesting finding of this study concerns the relationship between school-based Catholic religious education and the parish-based catechesis, where an existing relationship represents a weak source of religious education teachers’ satisfaction. This represents a valuable empirically driven insight regarding the Catholic religious education in Croatian schools with some importance to the broader context of religious education in general. 相似文献
