In general, books are not appropriate for all ages, so the aim of this work was to find an effective method of representing the age suitability of textual documents, making use of automatic analysis and visualization. Interviews with experts identified possible aspects of a text (such as ’is it hard to read?’) and a set of features were devised (such as linguistic complexity, story complexity, ...

In this study, an effective method for reliabilitybased design optimization is proposed enhancing sequential optimization and reliability assessment (SORA) method by a family of methods of moving asymptotes (MMA) approximations. In SORA, reliability estimation and deterministic optimization are performed sequentially. And the sensitivity and function value of probabilistic constraint at the mos...

We study numerically domain growth and interface fluctuations in oneand two-dimensional lattice systems composed of four species that interact in a cyclic way. Particle mobility is implemented through exchanges of particles located on neighboring lattice sites. For the chain we find that the details of the domain growth strongly depend on the mobility, with a higher mobility yielding a larger e...

The space heating in residential buildings accounts for a considerable amount of the primary energy use. Therefore, understanding the operation and performance of space heating systems becomes crucial in improving occupant comfort while reducing energy use. This study investigated the behavior of occupants adjusting their thermostat settings and heating system operations in a 62-unit affordable...

This paper explores the effect of feedback presentation formats in mobile fitness apps. Drawing from computers are social actors (CASA) paradigm, cognitive load theory (CLT), and social presence literature in this study, we conceptualize that when a user is involved in different types of exercise (aerobic or anaerobic) the exposure to more humanized feedback can create differential influence in...

2014 The critical properties of Ising models on various fractal lattices of the Sierpinski carpet type are studied using numerical simulations. We observe scaling and measure the exponents 03B3 and 03BD which are then compared to the values which have been recently extrapolated from the Wilson-Fisher 03B5-expansion in non integer dimensions. It appears that in the general case an effective dime...

This paper presents an effective method for clustering unknown speech utterances based on their associated speakers. The proposed method jointly optimizes the generated clusters and the required number of clusters according to a Bayesian information criterion (BIC). The criterion assesses a partitioning of utterances based on how high the level of within-cluster homogeneity can be achieved at t...

With the rapid progress of China’s urbanization, research on the automatic detection of land-use patterns in Chinese cities is of substantial importance. Deep learning is an effective method to extract image features. To take advantage of the deep-learning method in detecting urban land-use patterns, we applied a transfer-learning-based remote-sensing image approach to extract and classify feat...

This article presents Sil-Att, a simple and effective method for text clustering, which is based on two main concepts: the silhouette coefficient and the idea of attraction. The combination of both principles allows us to obtain a general technique that can be used either as a boosting method, which improves results of other clustering algorithms, or as an independent clustering algorithm. The ...

INTRODUCTION Accelerometers are becoming an increasingly important tool in the study of human movement. Their ease and affordability, combined with the potential to collect large amounts of continuous data outside the laboratory setting makes them excellent tools for gait analysis. Research has demonstrated the effectiveness of a single tri-axial accelerometer in measuring mean spatiotemporal p...
