We investigate the typical cycle lengths, the total number of cycles, and the number of finite cycles in random permutations whose probability involves cycle weights. Typical cycle lengths and total number of cycles depend strongly on the parameters, while the distributions of finite cycles are usually independent Poisson random variables. © 2012 Wiley Periodicals, Inc.

Interoperability is one of the major themes of research and development in information technology for the architecture, engineering, construction, and facilities management industries. A model-based approach to interoperability requires information structures that are standardized throughout the industry. The Industry Foundation Classes have been developed to provide this data exchange standard...

The paper presents a new 3D semantic building model dedicated to urban development. It provides the following special semantic features: storeys, passages, opening objects, and building variants, modelling different levels of detail and design respectively temporal variants. The model also includes a parametric part supporting easy generation of buildings and building variants in the urban desi...

In this study we examined the effectiveness of a computerbased geometry learning tool with 4 grade students. In both an experimental and control condition children constructed a series of common four-sided figures to fit a set of visual constraints. Additionally, children in the experimental condition were required to validate the presence of parallel segments, congruent segments, or right angl...

We present a model of visual working memory in ventral prefrontal cortex. Activation in ventral PFC consists of reverberating activity. Representations in ventral PFC are conjunctions of location and (partial) identity representations. With many objects, representations in ventral PFC interfere, which results in loss of information. Therefore, the number of objects in working memory is limited....

In Lowen and Wuyts (Appl Categ Struct 8:235–245, 2000) the authors studied the simultaneously concretely reflective and concretely coreflective subconstructs of the category Ap of approach spaces. For the sake of shortness we call such subconstructs stable. Using a technique introduced in Herrlich and Lowen (1999) it was possible to explicitly describe such stable subconstructs by a condition o...

A result of Johnson and Lindenstrauss [13] shows that a set of n points in high dimensional Euclidean space can be mapped into an O(log n/ )-dimensional Euclidean space such that the distance between any two points changes by only a factor of (1 ). In this note, we prove this theorem using elementary probabilistic techniques. © 2003 Wiley Periodicals, Inc. Random Struct. Alg., 22: 60–65, 2002

PURPOSE This paper is a report of a study of the effects of breastfeeding education on the breastfeeding success and breastfeeding characteristics of mothers in a Turkish context. METHODS The research was designed as quasi-experimental. The sample consisted of 93 mothers who participated in (n = 46) and did not participate in childbirth education classes (n= 47). The date was collected betwee...
