Tīmekļa lietotņu veiktspējas optimizācija izmantojot WebAssembly
2019
Bakalaura darba “Tīmekļa lietotņu veiktspējas optimizācija izmantojot WebAssembly” mērķis ir noskaidrot WebAssembly izmantošanas un nepieciešamības apstākļus, kā arī veikt pētijumu par tīmekļa lietotnes veiktspējas analīzi pēc moduļu pārstrādes uz WebAssembly kompilētu kodu, lai varētu noteikt, kad to ir vērts izmantot. Darbs sika sadalīts divās sadaļās. Pirmajā sadaļā tika veikta analīze par WebAssembly, tā darbības principiem, kā arī izmantošanu programmatūres izstrādē. Otrajā sadaļā tiks aprakstīts izveidotais projekts, kā arī salīdzināts tīmekļa lietotnes kods un veiktspēja pirms un pēc moduļu pārstrādes. Bakalaura darbs izklāstīts 20 lappusēs, ilustrēts ar 15 attēliem un 4 tabulām. Lit…
Microstructure and rheological response of laboratory-aged SBS-modified bitumens
2019
Polymer additives are widely used to improve the performance of road bitumens including their resistance to hardening during oxidation, although their oxidative inhibitor effect has not been well documented. This study aims to investigate the effect of laboratory-simulated ageing on the microstructure, and rheological properties of Polymer Modified Bitumens (PMBs) prepared with a Styrene-Butadiene-Styrene (SBS) copolymer and sulphur as a cross-linker. The laboratory ageing was conducted through the Rolling Thin Film Oven (RTFO) and the Pressure Aging Vessel (PAV) procedures. The unaged and aged binders were characterised using the Multiple Stress Creep and Recovery (MSCR) test, Gel Permeati…
CONSIDERAZIONI TEORICHE E PRATICHE SUL METODO DEL MASSIMO RETTANGOLO CIRCOSCRITTO PER LA VALUTAZIONE DELL’AMPIEZZA DELLA TENSIONE TANGENZIALE NEI CRI…
2012
The multiaxial fatigue criteria based on the approach of the critical plane require the determination of the amplitude of the alternating shear stress τ aacting on different planes passing through the point of the material analyzed. In the case of non-proportional stresses the shear stress vector varies both in modulus and direction and its tip describes a curvedefined loading path. In these cases τ ais identified and evaluated by means of special procedures the most recent, and apparently more effective, of which is that of the Maximum Circumscribed Rectangle (MCR) to the loading path itself. In particular τ ais equal to the length of the diagonal of the MCR. In this paper, the MCR method …
Improvements in the algorithms for the determination of the shear stress components in critical plane class fatigue criteria
2010
This paper presents two improvements in the procedure for the evaluation of the amplitude and mean values of the shear stress in critical plane class fatigue criteria, when the method of the Minimum Circumscribed Circle (MCC) to the path of the tip of the vector is used. In particular, the paper shows how it is possible to reduce the number of material planes passing through the point of interest in which the MCC has to be determined and the number of points of each curve that has to be considered for the determination of the MCC, noticeably reducing the computational time.
Oral Propranolol for Circumscribed Choroidal Hemangioma
2011
Introduction: Several therapeutic approaches have been developed to treat choroidal hemangioma. However, all these therapies are associated with a potential risk of damaging the overlying retina. Case Report: We report a case of circumscribed choroidal hemangioma (CCH) in a 59-year-old man refractory to laser treatment. Visual acuity was 20/200 and a serous macular detachment was present. The CCH was treated with oral propanolol, whereupon visual acuity improved to 20/20 and the macular detachment resolved without systemic or local adverse effects. Discussion: Propanolol is a β-blocker commonly used in cardiology that may induce endothelium vasoconstriction and inhibit endothelial prolifera…
Nebanku kredītdevēju ”SMScredit” un ”InCREDIT GROUP” lojalitātes programmas un to novērtējums
2016
Bakalaura darba temats ir „Nebanku kredītdevēju ”SMScredit” un ”InCREDIT GROUP” lojalitātes programmas un to novērtējums.” Darba mērķis ir lojalitātes programmu komunikācijas kanālu vērtējums un klientu vērtējums par programmu noderīgumu, to priekšrocībām un vai programmu darbības principi klientiem ir saprotami. Darbs sastāv no trīs daļām: teorētiskās, metodoloģiskās un empīriskās daļas. Teorētiskajā daļā tiek pētīta literatūra par mārketingu, integrētā mārketinga komunikāciju, patērētāju uzvedību un klientu lojalitāti. Darba metodoloģiskajā daļā tiek aplūkota teorija par kvantitatīvo un kvalitatīvo pētījuma metodi – aptauju un fokusa grupu. Darba nobeigumā tiek izdarīti secinājumi, izvērt…
