Robust three-dimensional best-path phase-unwrapping algorithm that avoids singularity loops.

2009

In this paper we propose a novel hybrid three-dimensional phase-unwrapping algorithm, which we refer to here as the three-dimensional best-path avoiding singularity loops (3DBPASL) algorithm. This algorithm combines the advantages and avoids the drawbacks of two well-known 3D phase-unwrapping algorithms, namely, the 3D phase-unwrapping noise-immune technique and the 3D phase-unwrapping best-path technique. The hybrid technique presented here is more robust than its predecessors since it not only follows a discrete unwrapping path depending on a 3D quality map, but it also avoids any singularity loops that may occur in the unwrapping path. Simulation and experimental results have shown that …

Synthetic Biology in Action

2014

Last decade has witnessed remarkable advances towards the engineering of life. The examples range from the design of an efficient cellular factory for the semi-synthesis of the antimalarial drug artemisinin, to the chemical synthesis of chromosomes, both bacterial and eukaryotic. In parallel, advances in the deep characterization of cell machineries in the simplest cells show that we are very far of fully understanding the regulation of metabolic and genetic circuits. Biological emergent properties and noise may suppose an obstacle for predictive design. Besides the obvious biotechnological benefits of synthetic biology, the path towards the artificial cell will report new insights on the e…

Using System Dynamics modelling to frame environmental voluntary commitment programs: the French experience

2021

This study stems from a research project aimed at investigating the factors facilitating and hampering the success of the EVE (Engagements Volontaires pour l’Environnement) program recently launched in France. Similarly to other countries, in which successfully environmental voluntary commitment programs are currently in place (SmartWay in the USA), EVE program aspires to improve transport operators efficiency and to reduce CO2 emissions in the environment. However, the multiple relationships between public and private actors involved in the program (ranging from the program coordinator to transport organisations), the complexity of transport and logistics sector (including the differences …

Infrastructure and system programming for digital ecosystems used in natural disaster management

2009

Researchers in most fields of activity must concentrate their efforts to eradicate or at least to mitigate the negative effects of “global warming”, which affect the entire planet. Within this context, we strongly believe that IT&C specialists should also approach the issue. Therefore, this paper presents the results and solutions obtained during the development of a research contract dealing on the one hand with real-time data collection and data centralization in a decision making system, and on the other with the dissemination of information among the people exposed to the effects of natural disasters such as: floods, storms, tsunamis, or other natural disasters which may destroy propert…

epiModel: A system to build automatically systems of differential equations of compartmental type-epidemiological models

2011

In this paper we describe epiModel, a code developed in Mathematica that facilitates the building of systems of differential equations corresponding to type-epidemiological linear or quadratic models whose characteristics are defined in text files following an easy syntax. It includes the possibility of obtaining the equations of models involving age and/or sex groups. © 2011.

Tolerance without clonal expansion: self-antigen-expressing B cells program self-reactive T cells for future deletion.

2008

Abstract B cells have been shown in various animal models to induce immunological tolerance leading to reduced immune responses and protection from autoimmunity. We show that interaction of B cells with naive T cells results in T cell triggering accompanied by the expression of negative costimulatory molecules such as PD-1, CTLA-4, B and T lymphocyte attenuator, and CD5. Following interaction with B cells, T cells were not induced to proliferate, in a process that was dependent on their expression of PD-1 and CTLA-4, but not CD5. In contrast, the T cells became sensitive to Ag-induced cell death. Our results demonstrate that B cells participate in the homeostasis of the immune system by abl…

Uz nestriktās matemātikas balstīta pieeja daudzkritēriju lineārām programēšanas problēmām

2022

Uz nestriktās matemātikas balstīta pieeja daudzkritēriju lineārām programēšanas problēmām. Šmits E., vadītāja Grigorenko O. Bakalaura darbs, 31 lappuses, 12 attēli, 4 literatūras avoti. Latviešu valodā. Vienas funkcijas maksimizēšana pie dotiem ierobežojumiem ir salīdzinoši vienkāršs un pašsaprotams process, savukārt, brīdī, kad ir nepieciešams maksimizēt divas vai vairāk mērķa funkcijas, uzdevuma atrisinājums var nebūt vairs tik skaidrs, jo dotās mērķa funkcijas var būt savstarpēji pretējas. Līdz ar to ir nepieciešams izstrādāt metodes, kas ļautu šāda tipa uzdevumus risināt. Darbā tika apkopota un pasniegta informācija par nestriktu pieeju vairāku mērķa funkciju lineārās programmēšanas uzd…

Characterization of the bulk flow properties of industrial powders from shear tests

2020

Bulk flow properties from shear analysis of compacted powders can be evaluated following different approaches. Experimental values of shear stresses obtained by conventional shear cells are traditionally used to build yield loci, from which the most relevant flow properties could be found. Such flow properties play an important role in determining their performance under fluidization conditions. In this work, a useful app, named cYield, was developed by using the new Matlab&rsquo

Šaha taktikas treniņprogramma

2017

Kvalifikācijas darba mērķis ir izstrādāt programmatūru, kas palīdzēs šahistiem uzlabot savas šaha taktiskās domāšanas spējas interaktīvi risinot šaha uzdevumus. Projekta ietvaros tika izveidota programmatūras prasību specifikācija un programmatūras projektējuma apraksts, tika veikta testēšana un tā tika aprakstīta dokumentācijā. Programma tiek veidota lai šahisti varētu trenēt sava taktiskās domāšanas spējas ar datora palīdzību, tādejādi papildinot savu trenēšanās iespēju klāstu un paātrinot treniņu procesu, jo atšķirībā no ierastās šahistu trenēšanās metodes, kur šahist izpēta jau izspēlētas šaha spēles reāla galdiņa, šaha situācijas tiek veidotas grafiskajā vidē, aiztaupot laiku, kas tiek…
