Fully pipelined real time hardware solution for High Efficiency Video Coding (HEVC) intra prediction

2016

International audience; A fully pipelined hardware accelerator for the High Efficiency Video Coding (HEVC) intra prediction is presented in this paper in order to reduce the computation complexity coming with this module and to accelerate the concerned calculations. Two reconfigurable structures are developed in this paper, the first one concerns angular modes and is identified as Processing Element for Angular (PEA) modes, the other is made in order to handle with the Planar mode and is identified as Processing Element for the Planar (PEP) mode. Each structure is repeated in five paths, that our architecture composed of, working in parallel way. This architecture supports all intra predict…

Rational normal curves and Hadamard products

2021

AbstractGiven $$r>n$$ r > n general hyperplanes in $$\mathbb P^n,$$ P n , a star configuration of points is the set of all the n-wise intersection of the hyperplanes. We introduce contact star configurations, which are star configurations where all the hyperplanes are osculating to the same rational normal curve. In this paper, we find a relation between this construction and Hadamard products of linear varieties. Moreover, we study the union of contact star configurations on a same conic in $$\mathbb P^2$$ P 2 , we prove that the union of two contact star configurations has a special h-vector and, in some cases, this is a complete intersection.

Crystallography of encapsulated molecules.

2017

The crystallography of supramolecular host–guest complexes is reviewed and discussed as a part of small molecule crystallography. In these complexes, the host binds the guests through weak supramolecular interactions, such as hydrogen and halogen bonding, cation–π, anion–π, C–H–π, π–π, C–H–anion interactions and the hydrophobic effect. As the guest often shows severe disorder, large thermal motion and low occupancies, the reliable crystallographic determination of the guest can be very demanding. The analysis of host–guest interactions using tools such as Hirshfeld and cavity volume surface analysis will help to look closely at the most important host–guest interactions. The jewel in the cr…

Elementary presentation of self‐consistent intermediate Hamiltonians and proposal of two totally dressed singles and doubles configuration interactio…

1994

Intermediate Hamiltonians are effective Hamiltonians which are defined on an N‐dimensional model space but which only provide n<N exact eigenvalues and the projections of the corresponding eigenvectors onto the model space. For a single root research, the intermediate Hamiltonian may be obtained from the restriction of the Hamiltonian to the model space by an appropriate, uniquely defined dressing of the diagonal energies or of the first column. Approximate self‐consistent dressings may be proposed. The simplest perturbative form gives the same result as the original 2nd order intermediate Hamiltonian or the ‘‘shifted Bk’’ technique but it is of easier implementation. Self‐consistent inclus…

Experience from Indoor Fire Search and Rescue Game Design for Technology Testing

2018

No matter how good the fire evacuation plan for a building is, there is a risk of immovable victims being left behind due to smoke obscuration, inhalation of poisonous gasses, or other reasons. Firefighters usually perform the search and rescue for casualties in responding to fire hazards, besides the firefighting. Among of the challenges in the search and rescue operation is how to locate victims, and to keep monitoring the fire development so that it will not accidentally harm the fire personnel. This paper presents a game designed to test a smartphone app’s feature that supports concurrent tracking of indoor victims and fire spread. 22 volunteers were assigned roles either as rescuers or…

Resting the mind – A novel topic with scarce insights. Considering potential mental recovery strategies for short rest periods in sports

2019

Abstract Both meticulously structured trainig routine as well as specific characteristics of various sports (e.g., swimming, shooting, modern pentathlon) with multiple competition bouts in a single day appear to be mentally demanding and may result in a state of mental fatigue. Due to these multidimensional demands, adequate training and competition recovery is essential. Consequently, the idea of mental recovery embraces the spotlight of research. On training and competition days, short rest periods implemented as a vital part, can be used for mental recovery and can help in assisting athletes to return to baseline levels of mental abilites (e.g., concentration, attention). Sport-specific …

Work-Related Stress, Physio-Pathological Mechanisms, and the Influence of Environmental Genetic Factors

2019

Work-related stress is a growing health problem in modern society. The stress response is characterized by numerous neurochemicals, neuroendocrine and immune modifications that involve various neurological systems and circuits, and regulation of the gene expression of the different receptors. In this regard, a lot of research has focused the attention on the role played by the environment in influencing gene expression, which in turn can control the stress response. In particular, genetic factors can moderate the sensitivities of specific types of neural cells or circuits mediating the imprinting of the environment on different biological systems. In this current review, we wish to analyze …

Root Canal Morphology and Configuration of the Mandibular Canine: A Systematic Review

2021

The aim of this study was to systematically review the root canal morphology and configuration (RCC) of mandibular canines (MaCa). The review was registered in the PROSPERO database (ID-272297) and it was carried out following the PRISMA guidelines. Three electronic databases (MEDLINE via PubMed, Embase, Scopus) were searched. Randomized controlled trials, cross-sectional, cohort, comparative, evaluation and validation studies have been included. The anatomical quality assessment (AQUA) tool was used for a quality assessment of the anatomical studies. Of 910 studies retrieved from the systematic search, 28 studies investigating RCCs were included. Most MaCa were single-rooted (87.9–100%), w…

Coordinate space calculation of two- and three-loop sunrise-type diagrams, elliptic functions and truncated Bessel integral identities

2019

We integrate three-loop sunrise-type vacuum diagrams in $D_0=4$ dimensions with four different masses using configuration space techniques. The finite parts of our results are in numerical agreement with corresponding three-loop calculations in momentum space. Using some of the closed form results of the momentum space calculation we arrive at new integral identities involving truncated integrals of products of Bessel functions. For the non-degenerate finite two-loop sunrise-type vacuum diagram in $D_0=2$ dimensions we make use of the known closed form $p$-space result to express the moment of a product of three Bessel functions in terms of a sum of Claussen polylogarithms. Using results fo…

"How to make a mountain out of a molehill": a corpus-based pragmatic and conversational analysis study of hyperbole in interation.

2006

Since antiquity figures have been widely studied within the framework of rhetoric, although contemporary rhetoric has tended to disregard their importance and relegate their study to the domain of literary criticism. However, since the 1980s, there has been a renewed interest in figurative language not only in literary studies, but also in other fields of research. Indeed, research on figuration has emerged as a new and distinct discipline, namely figurative language studies. However, within this framework, metaphor and irony have received the greatest attention, while other non-literal forms have been largely ignored. This is certainly the case of hyperbole, a long neglected trope despite …
