PURPOSE Continuity and discontinuity are controversial concepts in social theories on aging. The aim of this article is to explore these concepts using the experiences of older persons living in second couplehood in old age as a case in point. DESIGN AND METHOD Based on a larger qualitative study on second couplehood in old age, following the existential-phenomenological tradition, a theoreti...

As an important operator in polygon cluster generalization, the displacement has two contributions. One is to resolve the proximity conflicts to guarantee the legibility constraint. Another is to act as the prior operator of other generalization operator, such as aggregation. This paper presents a field based method to deal with the displacement of polygon cluster in both aspects above. On the ...

In this study, a computational framework is proposed for thermomechanical contact and debonding problems with proper thermal resistance at the interface. Using Variational Multiscale (VMS) framework, we present fully coupled formulation an explicit expression of pressure The considers quasi-static balance momentum transient heat transfer problem in fashion. At interface, two different constitut...

In this paper, a super-resolution algorithm tailored to enhance license plate numbers of moving vehicles in real traffic videos is proposed. The algorithm uses the information available from multiple, sub-pixel shifted, and noisy low-resolution observations to reconstruct a high-resolution image of the number plate. The image to be superresolved is modeled as a Markov random field and is estima...

Most off-the-shelf basic methodological tools currently used in pastoral development (e.g. technical definitions and conventional scales of observation) retain underlying assumptions about stability and uniformity being the norm (i.e. 'equilibrium thinking'). Such assumptions reflect a theoretical framework which had been questioned since the 1970s and was openly disproved in scientific circles...

An objective distance measure which is able to predict audible discontinuity in concatenated speech synthesis systems is very important. Previous works were primarily based on features estimated by linear and/or stationary models of speech. In this paper, we introduce two nonlinear approaches for the detection of discontinuity. The first method is based on a nonlinear harmonic model of speech w...

the central alborz mountains of northern iran (figure 1) is a zone of intense active continental deformation and is the most heavily populated region of iran, including the mega-city of tehran with a population of over 10 million. the region is affected by numerous active faults, some of them having great seismic potential, and documented historical seismicity. hence, the central alborz is a pr...

The track-structure interaction effects are usually analysed with conventional FEM programs, where it is difficult to implement the complex track-structure connection behaviour, which is nonlinear, elastic-plastic and depends on the vertical load. The authors developed an alternative analysis method, which they call the relative displacement method. It is based on the calculation of deformation...

Multiple Row Displacement (MRD) is a new dispatch technique for multi-method languages. It is based on compressing an n-dimensional table using an extension of the single-receiver row displacement mechanism. This paper presents the new algorithm and provides experimental results that compare it with implementations of existing techniques: compressed n-dimensional tables, look-up automata and si...

Abstract Studies on stress wave propagation across persistent joints have been conducted extensively. Nevertheless, there exists a consensus that non-persistent are widely and densely distributed, which profound impact in jointed rock masses. A boundary integral equation method is suggested this paper to investigate the characteristics of transmitted field for case single joint. The displacemen...
