Produits transformés, entre science et science-fiction
2021
En science-fiction, le futur de nos tables a souvent été mis en scène : des bouilles nutritives de Matrix aux pâtes d'insectes de Snowpiercer, ou bien aux légumes géants de Woody et les robots. Comment mangerons-nous dans le futur ? Nos goûts changeront-ils comme nos plats? Et dans l'espace, est-ce que la mayonnaise prendra sur l'ISS?
Bērnu literatūras tulkošanas īpatnības (pamatojoties uz D. Harmsa daiļrades materiālu).
2021
Darbā tiek aplūkotas tulkošanas īpatnības bērnu literatūras jomā, pamatojoties uz D. Harmsa darbu tulkojumiem latviešu valodā. Praktiskajā daļā tiek analizēti piemēri no oriģinālajiem un tulkotajiem darbiem, kā arī tiek analizēti bērnu poētisko tekstu uzbūves principi. Īpaša uzmanība darbā tiek veltīta bērnu literatūras poētiskā teksta tulkošanas īpatnībām. Autors balsta analīzi uz bērnu avangarda literatūras sarežģītās valodas mūsdienu tulkojumiem. Šis darbs var ieinteresēt filologus, tulkus, kā arī citus ieinteresētos lasītājus.

Merging the transform step and the quantization step for Karhunen-Loeve transform based image compression
2000
Transform coding is one of the most important methods for lossy image compression. The optimum linear transform - known as Karhunen-Loeve transform (KLT) - was difficult to implement in the classic way. Now, due to continuous improvements in neural network's performance, the KLT method becomes more topical then ever. We propose a new scheme where the quantization step is merged together with the transform step during the learning phase. The new method is tested for different levels of quantization and for different types of quantizers. Experimental results presented in the paper prove that the new proposed scheme always gives better results than the state-of-the-art solution.
Effects of pressure and of thermal history on the structural phase transition of KCN
1992
The cubic-noncubic structural phase transition of a KCN single crystal is studied as a function of thermal history and of hydrostatic pressure up to 2 kbar. The standard sequence of phases is cubic-monoclinic-orthorhombic on cooling and orthorhombic-cubic on heating. The monoclinic phase is also absent in first cooling runs at low pressures (p≦250 bar). The width of the monoclinic field inp, T phase diagram is increased in second cooling runs. The effects are discussed in terms of a martensitic transformation behavior and random strain fields.
Martensitic phase transformation cubic-orthorhombic of NaCN and (NaCN)0.98 (KCN)0.02
1990
The ferroelastic cubic-orthorhombic transition of single crystals NaCN and (NaCN)0.98 (KCN)0.02 has been studied by x-ray diffraction. The domain configuration obtained is consistent with the Wechsler, Lieberman, Read-model for martensitic transformations.
A CUDA-based implementation of an improved SPH method on GPU
2021
We present a CUDA-based parallel implementation on GPU architecture of a modified version of the Smoothed Particle Hydrodynamics (SPH) method. This modified formulation exploits a strategy based on the Taylor series expansion, which simultaneously improves the approximation of a function and its derivatives with respect to the standard formulation. The improvement in accuracy comes at the cost of an additional computational effort. The computational demand becomes increasingly crucial as problem size increases but can be addressed by employing fast summations in a parallel computational scheme. The experimental analysis showed that our parallel implementation significantly reduces the runti…

Very Early Presentation of Extrahepatic Portal Vein Obstruction Causing Portal Hypertension in an Infant: Uncertainties in the Management and Therape…
2016
Extrahepatic portal vein obstruction, although rare in children, is a significant cause of portal hypertension (PHT) leading to life-threatening gastrointestinal bleeding in the pediatric age group. PHT may also lead to other complications such as hyperesplenism, cholangyopathy, ascites, and even hepatopulmonary syndrome and portopulmonary hypertension that may require organ transplantation. Herein we report the case of an asymptomatic 11-month-old infant wherein a hepatomegaly and cavernous transformation of the portal vein was detected by liver ultrasound. Neither signs of thrombosis in arteriovenous system, nor affectation of biliary tract were identified in the magnetic resonance imagin…
The Radon-Wigner Transform and Its Application to First-order Optical Systems
2009
The Radon-Wigner transform is presented as a tool for the description of 1st-order optical systems. The input/output relationships for this phase-space representation are obtained and their application in analysis and design tasks is pointed out.
