Parallel computing must meet seemingly contradictory goals: software development should be carried out in an architecture-and technology-independent environment, while both algorithms and system software should take full advantage of the features of the underlying parallel architecture. At the same time, application programmers cannot be expected to be parallel processing experts. Usability, sc...

U) The topic model is a popular probabilistic model for text and document modeling. It can be used for topic indexing, document classification, corpus summarization and information retrieval. In the past, topic models have been applied to corpora containing thousands to hundreds of thousands of documents. Now there is an increasing need to model collections with millions to billions of document...

The parallel programming landscape is constantly changing and becoming enriched with new languages, tools and techniques. In this chapter we give a survey on the different parallel programming models available today. These models are suitable for general-purpose computing but are also suitable for programming specialized (e.g. embedded) systems that offer the required facilities. We start by ca...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

background: a precise impression is mandatory to obtain passive fi t in implant-supported prostheses. the aim of this study was to compare the accuracy of three impression materials in both parallel and nonparallel implant positions. materials and methods: in this experimental study, two partial dentate maxillary acrylic models with four implant analogues in canines and lateral incisors areas w...

While progress has been made in identifying common genetic variants associated with human diseases, for most of common complex diseases, the identified genetic variants only account for a small proportion of heritability. Challenges remain in finding additional unknown genetic variants predisposing to complex diseases. With the advance in next-generation sequencing technologies, sequencing stud...
