What Are the Rules of the Game? Some Remarks on The Yellow Jacket

1995

The vast caravan out of Ceylon … arrived safely in Europe in April 1884 … There were sixty-seven people, twenty-five elephants … and a great many oxen of various kinds. The ethnographic exhibition included hundreds of different shows, and even the vegetative world was represented in numerous exhibits … My Singhalese troupe was veiled in the ancient wondrous world of India; not only had we captured the vibrant, picturesque, outward appearance of India, but also the shimmer of its mystique. The colourful, captivating sight of the caravanserai, the majestic elephants, partly bedecked in golden saddlery, partly in work harnesses, pulling gigantic loads; the slim, attractive, doe-eyed dancers wi…

Study of the reactive dynamics of nanometric metallic multilayers using Molecular Dynamics: the Al−Ni system

2012

A molecular dynamics study of a layered Ni-Al-Ni system is developed using an embedded atom method potential. The specific geometry is designed to model a Ni-Al nanometric metallic multilayer. The system is initially thermalized at the fixed temperature of 600 K. We first observe the interdiffusion of Ni and Al at the interfaces, which is followed by the spontaneous phase formation of B2-NiAl in the Al layer. The solid-state reaction is associated with a rapid system's heating which further enhances the diffusion processes. NiAl phase is organized in small regions separated by grain boundaries. This study confirms the hypothesis of a layer-by-layer development of the new phase. For longer t…

DEMO: Unconventional WiFi-ZigBee communications without gateways

2014

Nowadays, the overcrowding of ISM bands is becoming an evident limitation for the performance and widespread usage of 802.11 and 802.15.4 technologies. In this demo, we prove that it is possible to opportunistically exploit the inter-technology interference between 802.11 and 802.15.4 to build an unconventional low-rate communication channel and signalling protocol, devised to improve the performance of each contending technology. Differently from previous solutions, inter-technology communications do not require the deployment of a gateway with two network interfaces, but can be activated (when needed) directly between two heterogeneous nodes, e.g. a WiFi node and a ZigBee node. This capab…

The model for public television and the young audience’s expectations. Differences between Great Britain and Spain in the perception of qualities and…

2017

Public service media (PSM) are in crisis throughout Europe. As a scenario for research, the two extremes of the background have been chosen: the first, BBC, is at the heart of media system, has become a model for the others and has just finished the particularly delicate challenge of renewal the fundamental law that is to rule over the next ten years; the second is on the periphery of public television, and in the extreme circumstances in Spain that have driven some of the television corporations to extinction, such as Canal 9 -Radiotelevisió Valenciana (RTVV). Using a method based on the use of semi-structured interviews and Delphi, the conception of these media models among their respecti…

Attentional processing biases to threat in schizophrenia: Evidence from a free-viewing task with emotional scenes

2021

Attentional biases to threatening stimuli have been suggested to play a key role in the onset and course of schizophrenia. However, current research has not completely demonstrated this assumption. The aim of this eye-tracking study was to shed light on the underlying psychological mechanisms of schizophrenia by examining the attentional processing of socio-emotional information. Forty-four individuals with schizophrenia and 47 healthy controls were assessed in a 3-s free-viewing task with a social scene (i.e., happy, threatening, or neutral) in competition with a non-social one to determine the effects of emotional information on the different stages of the attentional processing. The loca…

A user-friendly control system to easy reconfigure a manufacturing cell

2006

Generic manufacturing enterprises need to interact with an environment characterized by a strong competition. In order to react to the mutable requests of market, control systems should confer to the manufacturing system capabilities for easy modifiability, and this can be achieved by reducing the necessary time to reconfigure the existing system. Following this main requirement, this paper presents a user-friendly control system that pursues three operational goals: - Ability to easy re-program the sequence of operations of the manufacturing equipments of a manufacturing cell; - Reconfigurability of the system, by allowing to add/remove a new/existing component in/from the manufacturing ce…

Array programming with NumPy.

2020

Array programming provides a powerful, compact and expressive syntax for accessing, manipulating and operating on data in vectors, matrices and higher-dimensional arrays. NumPy is the primary array programming library for the Python language. It has an essential role in research analysis pipelines in fields as diverse as physics, chemistry, astronomy, geoscience, biology, psychology, materials science, engineering, finance and economics. For example, in astronomy, NumPy was an important part of the software stack used in the discovery of gravitational waves1 and in the first imaging of a black hole2. Here we review how a few fundamental array concepts lead to a simple and powerful programmi…

AnySeq: A High Performance Sequence Alignment Library based on Partial Evaluation

2020

Sequence alignments are fundamental to bioinformatics which has resulted in a variety of optimized implementations. Unfortunately, the vast majority of them are hand-tuned and specific to certain architectures and execution models. This not only makes them challenging to understand and extend, but also difficult to port to other platforms. We present AnySeq - a novel library for computing different types of pairwise alignments of DNA sequences. Our approach combines high performance with an intuitively understandable implementation, which is achieved through the concept of partial evaluation. Using the AnyDSL compiler framework, AnySeq enables the compilation of algorithmic variants that ar…
