Dual attachment pairs in categorically-algebraic topology

2011

[EN] The paper is a continuation of our study on developing a new approach to (lattice-valued) topological structures, which relies on category theory and universal algebra, and which is called categorically-algebraic (catalg) topology. The new framework is used to build a topological setting, based in a catalg extension of the set-theoretic membership relation "e" called dual attachment, thereby dualizing the notion of attachment introduced by the authors earlier. Following the recent interest of the fuzzy community in topological systems of S. Vickers, we clarify completely relationships between these structures and (dual) attachment, showing that unlike the former, the latter have no inh…

The Greenland shark Somniosus microcephalus—Hemoglobins and ligand-binding properties

2017

A large amount of data is currently available on the adaptive mechanisms of polar bony fish hemoglobins, but structural information on those of cartilaginous species is scarce. This study presents the first characterisation of the hemoglobin system of one of the longest-living vertebrate species (392 +/- 120 years), the Arctic shark Somniosus microcephalus. Three major hemoglobins are found in its red blood cells and are made of two copies of the same a globin combined with two copies of three very similar beta subunits. The three hemoglobins show very similar oxygenation and carbonylation properties, which are unaffected by urea, a very important compound in marine elasmobranch physiology.…

Aggregation of [Ln(12)(III)] clusters by the dianion of 3-formylsalicylic acid. Synthesis, crystal structures, magnetic and luminescence properties

2019

Three isostrucutral dodecanuclear clusters with the general formula [Ln(12)(fsa)(12)(mu f(3)-OH)(12)(DMF)(12)]center dot nDMF (fsa(2-) is the dianion of 3-formylsalicylic acid; Ln = Eu 1, Gd 2, Dy 3) have been obtained from the reaction of fromylsalicyclic acid (H(2)fsa), tetrabutylammonium hydroxide and Ln(NO3)(3)center dot 6H(2)O in methanol/DMF. Their structure consists of four vertex-sharing heterocubanes. Each heterocubane unit is assembled from four Ln(III) ions, three mu(3)-OH groups and one mu(3)-oxygen atom arising from the fsa(2-) carboxylato group. The photophysical properties of the europium derivative investigated at both 300 and 80 K sustain a relative intense emission obtaine…

High-pressure characterization of multifunctional CrVO4

2020

[EN] The structural stability and physical properties of CrVO(4)under compression were studied by x-ray diffraction, Raman spectroscopy, optical absorption, resistivity measurements, andab initiocalculations up to 10 GPa. High-pressure x-ray diffraction and Raman measurements show that CrVO(4)undergoes a phase transition from the ambient pressure orthorhombic CrVO4-type structure (Cmcm space group, phase III) to the high-pressure monoclinic CrVO4-V phase, which is proposed to be isomorphic to the wolframite structure. Such a phase transition (CrVO4-type -> wolframite), driven by pressure, also was previously observed in indium vanadate. The crystal structure of both phases and the pressure …

MoMo: enabling hybrid museums

2005

Present-day museums are not mere passive institutions for the preservation of a society's cultural heritage. They have become instead learning environments, research centres and even tourist attractions. The paper introduces the notion of a hybrid museum (HM) in which wireless personal digital devices (PDAs) are used to tailor digital contents to the visitor to enrich both the learning and entertainment experience. The paper describes a fully functional hybrid museum infrastructure (MoMo) implemented with the.NET compact framework running on the PocketPC platform. Several research challenges that had to be faced during the implementation of the system such as the exploration of large sets o…

Servisu orientētas arhitektūras veiktspēja

2017

Mūsdienās, veidojot informācijas sistēmas, nepieciešams tās veidot elastīgas un daudzfunkcionālas, lai varētu nodrošināt klientu vēlmes un spēt sekot līdzi strauji mainīgajai pasaulei. Lai to nodrošinātu, informācijas sistēmas bieži tiek veidotas balstoties uz Servisu orientētu arhitektūru, kurā sistēmas funkcionālā daļa tiek veidota atsevišķi un smalki sadalīta. Darbā apskatītas servisu orientētas arhitektūras, to realizācija un pielietojumi, veiktspējas problēmas, un risinājumi, kā tās samazināt. Izmantojot iegūto informāciju, veikts šo risinājumu salīdzinājums, kurš izmantots lēmumu koka izveidē. Balstoties uz iegūto lēmumu koku, izvēlēts viens no risinājumiem, kas izmantots informācijas…

Code Contracts ja ComTest-yksikkötestausgenerointi .NET-kielissä

2015

Opetuksen tehostamiseen suunnattu työkalu ComTest osaa luoda yksikkötestejä koodin kommentteihin kirjoitettujen ohjeiden perusteella. Sopimuspohjaisessa suunnittelussa olion metodeille asetetaan ehtoja, joiden on oltava voimassa ennen operaation suorittamista tai sen jälkeen. Tällaiset ehdot voidaan automaattisesti kirjoittaa osaksi koodin kommentteja. Code Contracts on laajennos .NET-kieliin, jonka avulla sopimuspohjainen suunnittelu saadaan osaksi sovelluskehitystä. Tutkimuksessa selvitetään, miten ComTest ja Code Contracts liittyvät toisiinsa. ComTest, a tool mainly directed to make teaching more efficient, is able to create Unit Tests based on directions written in the code comments. In…

Microsoft .NET Core tehnoloģijas izmantošana

2018

Kristapa Cjaputas maģistra darba galvenais mērķis ir izpētīt ASP.NET Core ietvaru, lai šo tehnoloģiju pielietotu praktiskas lietojumprogrammas izstrādē, kuru varētu darbināt gan uz Windows, gan uz Linux serveru platformām. Mērķa sasniegšanai tika padziļināti izpētīta pieejamā literatūra un ietvara darbība Windows un Linux vidēs, veikti ātrdarbības mērījumi, kā arī ietvars salīdzināts ar citiem populāriem tīmekļa ietvariem. Darba gaitā, padziļināti pētot un izmantojot ietvaru lietojumprogrammas izstrādē, varēja saskarties gan ar plusiem, gan mīnusiem tā pielietojumā. Salīdzinot tīmekļa ietvaru ar citiem populāriem ietvariem nevar konkrēti noteikt, kurš ir labāks par citu, jo ne vienmēr visi …

Ietvaru salīdzināšana tīmekļa lietotnes ģenerēšanai no datu modeļa

2018

Tīmekļa vietņu apjoms visā pasaulē arvien palielinās, tāpēc ir nepieciešams pēc dažādu sarežģītību veidu tīmekļa vietnēm. Lai ātri un ērti izveidotu tīmekļa vietni, ar vai bez noteiktām biznesa prasībām, nepieciešams ņemt vērā dažādi faktori kā tiks veidota tīmekļa vietne. Darba mērķis ir salīdzināt programmu ietvarus tīmekļa vietņu ģenerēšanai, balstoties uz iepriekš izveidotas datu bāzes. Tiks izpētīts ietvaru rīku funkcionālās iespējas un pielāgošana noteiktām vajadzībām. Svarīgs vērtēšanas kritērijs ir ietvaru piedāvātie palīgrīki izstrādes gaitas paātrināšanai. Pēc šiem kritērijiem izvēlētie ietvari tiks salīdzināti un iegūti secinājumi.
