underlying representations play a crucial role in capturing predictable relations among different phonetic categories in phonological theory. Tone sandhi is a tonal alternation phenomenon in which a tone changes to a different tone in certain phonological environments. This study investigates whether Taiwanese listeners are more sensitive to the surface form of the tones or the underlying tonal...

Economists and sociologists disagree over markets’ potential to substitute for networks of private connections. In this paper we focus on the transmission of information in labor markets and study a model where workers differ in their (ex ante unobservable) productivity. Before entering the market, individuals can pay a cost and either establish a link to a currently employed worker ("network")...

HPC systems now exploit GPUs within their compute nodes to accelerate program performance. As a result, high-end application development has become extremely complex at the node level. In addition to restructuring the node code to exploit the cores and specialized devices, the programmer may need to choose a programming model such as OpenMP or CPU threads in conjunction with an accelerator prog...

The increasing demand for bandwidth coupled with saturating electrical systems is leading the drive for optics as an interconnect technology. Highperformance computing systems (HPCS) consist of a large number of components such as processors, memories, and interconnection links. As the number of components in HPCS increases, the probability of a failure also increases. Therefore, it becomes imp...

This paper presents an object-based scene segmentation algorithm which combines the temporal information (e.g. motion) from video and image cues from individual frame. First a motionbased segmentation is decided based on the Hierarchical Principal Component Split (HPCS) algorithm for multi-moving-object motion classification. HPCS is a binary-tree-structured recursive procedure which clusters t...

In a series of talks at the recent Intel Developers Forum, the company tantalized industry watchers by dribbling out a few more details about its IA-64 instruction set and its first implementation, Merced. In a joint presentation by Intel’s John Crawford and Hewlett-Packard’s Jerry Huck, the two architects shed additional light on the IA-64 design. They provided further details on the architect...

GPUs and other accelerators are popular devices for accelerating compute-intensive, parallelizable applications. However, programming these devices is a difficult task. Writing efficient device code is challenging, and is typically done in a low-level programming language. High-level languages are rarely supported, or do not integrate with the rest of the high-level language ecosystem. To overc...

abstract purpose: this research aimed to investigate the relationship between organizational spirituality and productivity of librarians and library staff in libraries of shiraz university and also determining the influential and the most predictive indicator to improve employee productivity. methodology: to collect data two questionnaires were used; the first one measured the persons spiritual...
