PADRE pixel read-out architecture for Monolithic Active Pixel Sensor for the new ALICE Inner Tracking System in TowerJazz 180 nm technolog
ALICE (A Large Ion Collider Experiment) is the heavy-ion experiment at the Large Hadron Collider (LHC) at CERN. As an important part of its upgrade plans, the ALICE experiment will schedule the installation of a new Inner Tracking System (ITS) during the Long Shutdown 2 (LS2) of the LHC. The new ITS...
Distributed Architecture to Integrate Sensor Information: Object Recognition for Smart Cities
Modelling the cohesive sediment transport in the marine environment: the case of Thermaikos Gulf
The transport of fine-grained sediments in the marine environment entails risks of pollutant intrusions from substances absorbed onto the cohesive flocks' surface, gradually released to the aquatic field. These substances include nutrients such as nitrate, phosphate and silicate compounds from drain...

Assessing the Moisture Transports Associated With Nocturnal Low-Level Jets in Continental South America
Given the crucial role of low-level circulation in convective events, this study presents a climatological characterization of the moisture sources and sinks associated with the occurrence of nocturnal low-level jets (NLLJs) in South America. Six selected NLLJ cores are identified according to the j...
Optimal Power Control of Inverter-Based Distributed Generations in Grid-Connected Microgrid
Distributed generation (DG) units are utilized to feed their closed loads in the autonomous microgrid. While in the grid-connected microgrid, they are integrated to support the utility by their required real and reactive powers. To achieve this goal, these integrated DGs must be controlled well. In...
Benchmark of nanoparticle tracking analysis on measuring nanoparticle sizing and concentration
One of the greatest challenges in the manufacturing and development of nanotechnologies is the requirement for robust, reliable, and accurate characterization data. Presented here are the results of an interlaboratory comparison (ILC) brought about through multiple rounds of engagement with NanoSigh...
Plankton dynamics in a cyclonic eddy in the Southern California Current System
International audience The California Current System is an eastern boundary upwelling system (EBUS) with high biological production along the coast. Oligotrophic offshore waters create cross-shore gradients of biological and physical properties, which are affected by intense mesoscale eddy activity....

Influence of dead-water zones on the dispersive mass-transport in rivers
The dispersive mass transport in rivers has been investigated to improve the predictability of transport scenarios in case of accidental pollutant spills. In particular, the influence of dead-water zones, as they are given by groin fields, on the transport characteristics in the main stream has been...
EGFR inhibition by curcumin in cancer cells : a dual mode of action
Epidermal Growth Factor Receptor (EGFR) is a common target of anticancer therapy. Nowadays the search for new molecules inhibiting this receptor is turning towards natural substances. One of the most promising natural compounds that have shown an anti-EGFR activity is curcumin, the polyphenol found...

A Smart Surveillance System for People Counting and Tracking Using Particle Flow and Modified SOM
Based on the rapid increase in the demand for people counting and tracking systems for surveillance applications, there is a critical need for more accurate, efficient, and reliable systems. The main goal of this study was to develop an accurate, sustainable, and efficient system that is capable of...
Jellyfish Search Optimization Algorithm for MPP Tracking of PV System
Because of the rapid increase in the depletion rate of conventional energy sources, the energy crisis has become a central problem in the contemporary world. This issue opens the gateway for exploring and developing renewable energy sources to fulfill the exigent energy demand. Solar energy is an ab...
Dynamic crack propagation in weak snowpack layers: insights from high-resolution, high-speed photography
Dynamic crack propagation in snow is of key importance for avalanche release. Nevertheless, it has received very little experimental attention. With the introduction of the propagation saw test (PST) in the mid-2000s, a number of studies have used particle tracking analysis of high-speed video recor...
Stochastic upscaling of hydrodynamic dispersion and retardation factor in a physically and chemically heterogeneous tropical soil
Particle Tracking Random Simulation of Pollutant Migration and Diffusion
A two-step Lagrangian particle tracing method was used to simulate the particle movement in convective diffusion. Firstly, the flow field distribution was given by finite difference method. Secondly convective diffusion was simulated by particle tracing method. Jet current through centre slit in the...
Monte Carlo Methods for Tempo Tracking and Rhythm Quantization
We present a probabilistic generative model for timing deviations in expressive music performance. The structure of the proposed model is equivalent to a switching state space model. The switch variables correspond to discrete note locations as in a musical score. The continuous hidden variables den...
Color and motion-based particle filter target tracking in a network of overlapping cameras with multi-threading and GPGPU Rastreo de objetivos por medio de filtros de partículas basados en color y movimiento en una red de cámaras con multi-hilo y GPGPU
This paper describes an efficient implementation of multiple-target multiple-view tracking in video-surveillance sequences. It takes advantage of the capabilities of multiple core Central Processing Units (CPUs) and of graphical processing units under the Compute Unifie Device Arquitecture (CUDA) fr...
Attrition and dust formation of pure and core-shell SiC powders
A recent innovation in concentrating solar systems makes use of a new heat transfer fluid (htf) that operates in such a way that a dense suspension of SiC particles acts as a heat transfer fluid with a heat capacity similar to the molten salts traditionally used as a HTF in concentrated solar energy...
Estimation of effective porosity in large-scale groundwater models by combining particle tracking, auto-calibration and 14C dating
Effective porosity plays an important role in contaminant management. However, the effective porosity is often assumed to be constant in space and hence heterogeneity is either neglected or simplified in transport model calibration. Based on a calibrated highly parametrized flow model, a three-dimen...
