Les Expressions Figées des Verbes Ser et Estar Suivies de Prép X

1996

The present work is based on the methodological setting of the LADL studies. In order to establish the body subject to analysis, we selected only the fixed phrases N0 ser/estar Prep X. In this way, we have collected 1138 expressions involving estar Prep X, and 534 with ser Prep X. In order to classify these expressions, we have grouped them according to the number and form of their complements. As to the part pertaining to semantics, the alphabetical indices have allowed us to establish that, concerning ser and estar, all the formal schemes exists for both Spanish and french, at least under the form of fixed expressions. As to the part concerning translation, we have attempted to mesure the…

Parallel macro pipelining on the intel SCC many-core computer

2013

In this paper we present how Intel's Single-Chip-Cloud processor behaves for parallel macro pipeline applications. Subsets of the SCC's available cores can be arranged as a pipeline where each core processes one stage of the overall workload. Each of the independent cores processes a small part of a larger task and feeds the following core with new data after it finishes its work. Our case-study is a parallel rendering system which renders successive images and applies different filters on them. On normal graphics adapters this is usually done in multiple cycles, we do this in a single pipeline pass. We show that we can achieve a significant speedup by using multiple parallel pipelines on t…

RabbitMash: accelerating hash-based genome analysis on modern multi-core architectures

2020

Abstract Motivation Mash is a popular hash-based genome analysis toolkit with applications to important downstream analyses tasks such as clustering and assembly. However, Mash is currently not able to fully exploit the capabilities of modern multi-core architectures, which in turn leads to high runtimes for large-scale genomic datasets. Results We present RabbitMash, an efficient highly optimized implementation of Mash which can take full advantage of modern hardware including multi-threading, vectorization and fast I/O. We show that our approach achieves speedups of at least 1.3, 9.8, 8.5 and 4.4 compared to Mash for the operations sketch, dist, triangle and screen, respectively. Furtherm…

THE HOUSE THAT IS NOT THERE: THE HOME FEELING IN JONATHAN RABAN’S LANGUAGE IN FOREIGN LAND

2021

This work aims to analyse the novel of the journalist and novelist Jonathan Raban, Foreign Land, trying to highlight how, through the language used, the author manages to elaborate a personal, intimate and even dramatic vision of themes such as the relationship between man and the environment, the sense of uprooting and the love for the sea that are typical themes of travel literature within which this novel is enrolled. More specifically, the text, taken from a work of reading analysis and translation of the Rabanian work from English to Italian, aims to highlight the metaphorical dimension of the home feeling made particularly effective by the parallelism between the inner dimension of th…

On 2-(n^2,2n,2n-1) designs with three intersection numbers

2007

The simple incidence structure $${\mathcal{D}(\mathcal{A},2)}$$ , formed by the points and the unordered pairs of distinct parallel lines of a finite affine plane $${\mathcal{A}=(\mathcal{P}, \mathcal{L})}$$ of order n > 4, is a 2 --- (n 2,2n,2n---1) design with intersection numbers 0,4,n. In this paper, we show that the converse is true, when n ? 5 is an odd integer.

Total curvatures of convex hypersurfaces in hyperbolic space

1999

We give sharp upper estimates for the difference circumradius minus inradius and for the angle between the radial vector (respect to the center of an inball) and the normal to the boundary of a compact $h$-convex domain in the hyperpolic space. We apply these estimates to get the limit at the infinity for the quotients Volume/Area and (Total $k$-mean curvature)/Area of a family of $h$-convex domains which expand over the whole space. The theorem for the first quotient gives an extension to arbitrary dimension of a result of Santalo and Yanez for the hyperbolic plane.

As concluding remarks to the European Few-Body Conference, the author presents a parallelism between the Few-Body and the Many-Body theories along the last years.

Lattice Boltzmann Simulations at Petascale on Multi-GPU Systems with Asynchronous Data Transfer and Strictly Enforced Memory Read Alignment

2015

The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently general-purpose graphics processing units have become accessible as high-performance computing resources at large-scale. We report on implementing a lattice Boltzmann solver for multi-GPU systems that achieves 0.69 PFLOPS performance on 16384 GPUs. In addition to optimizing the data layout on the GPUs and eliminating the halo sites, we make use of the possibility to overlap data transfer between the host CPU and the device GPU with computing on the GPU. We simulate flow in porous media and measure both strong and weak scaling performance with the emphasis being on a large scale…

A PC-based low cost impedance and gain-phase analyzer

2008

Abstract In this paper, we present a practical and inexpensive impedance/gain-phase analyzer (IGPA), which is very useful in the design of electronic circuits. This instrument allows the Bode diagram of any network or electronic circuit with an input and an output to be obtained, even though this implementation was not previously known. It can also obtain the module and phase diagrams of any impedance separately. The device under test (DUT) is connected to a personal computer (PC) via the parallel port by means of an electronic circuit implemented for this purpose. The results are shown on the screen of the PC and can be accessible for use in any further operation. The instrument operates i…
