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…
IT projekta pārcelšana uz Microsoft Azure mākoņa platformu
2015
Pēdējo gadu laikā, strauji pieaugot interneta ātrumam un izplatībai, palielinās uzņēmumu interese par projektu izstrādi un uzturēšanu mākonī. Microsoft piedāvā produktu Azure, kas nodrošina ērtu un elastīgu risinājumu projektu uzturēšanai un izstrādei apvienojumā ar iespējām mainīt nepieciešamos datu apstrādes un skaitļošanas resursus, saglabājot salīdzinoši mazas izmaksas. Microsoft Azure piemērots visa izmēra projektiem. Darbā aplūkotas galvenās lietas, par ko jāpadomā pirms sākt projekta pārcelšanu uz Microsoft Azure un galvenās problēmas, kādas varētu rasties, pārceļot, izstrādē jau esošu projektu uz Microsoft Azure mākoņa platformu. Salīdzinātas priekšrocības un trūkumi projekta uzturē…
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.

Nodrošināt pārvaldību EDS dokumentam un iegūt PDF un XLS dokumentus, kā arī XML dokumentu, kuru var nodot VID EDS sistēmai. Risinājums tika izstrādāts, izmantojot PL/SQL Developer, Microsoft Visual Studio rīkus, .Net, .NET MVC.
Emotions and Digital Delivery Platforms
2021
From the global spread of the infectious disease COVID-19, in Argentina as in other states worldwide, health measures, social emergency, economic and public order measures were taken. One of the main and earliest measures of social order in the face of this disease was the delimitation of a period of population isolation, known as preventive and obligatory social isolation. The compulsory social isolation generated unprecedented growth in the demand for services to the platform economies in Argentina in general and in Buenos Aires in particular, causing the platform delivery activity to be conceived as an essential activity. The purpose of the writing is to explore the configuration of a ce…
Generalised bisection method for optimum ultrasonic ray tracing and focusing in multi-layered structures
2021
Ultrasonic testing has been used for many decades, proving itself very efficient for detecting defects in many industrial sectors. The desire to apply ultrasonic testing to geometrically complex structures, and to anisotropic, inhomogeneous materials, together with the advent of more powerful electronics and software, is constantly pushing the applicability of ultrasonic waves to their limits. General ray tracing models, suitable for calculating the proper incident angle of single element probes and the proper time delay of phased array, are currently required. They can support the development of new imaging techniques, as Full Matrix Capture and Total Focusing Method, and the execution of …
Measurements on partial discharge in on‐site operating power transformer: a case study
2018
This study presents the case study of a substation in-service power transformer referred to the on-site partial discharge (PD) detection and evaluation methods. An original methodology for simultaneous application of three methods is proposed: electrical, acoustic and ultra-high frequency. Transformer is powered by the power grid and no external generator is required according to the proposed methodology. Furthermore, several possibilities of applying these concurrent measurements and benefits of such solution in terms of result interpretation, interference resistance and on-site measurement applicability are indicated. The proposed methodology allows for a fast, accurate and secure PD diag…
Custom measurement system for memristor characterisation
2021
Abstract A cheap, compact and customisable characterisation system for memristor devices, working between ± 10 V, is presented. SPICE (Simulation Program with Integrated Circuit Emphasis) simulations are performed to verify the circuit feasibility and a proper software is developed to drive the system. The potentiality of the realised system is tested by performing several electrical measurements on both Cu/HfO2/Pt memristors and two-terminals commercial devices.
Rivalry of diffusion, external field and gravity in micro-convection of magnetic colloids
2019
Magnetic fields and magnetic materials have promising microfluidic applications. For example, magnetic micro-convection can enhance mixing considerably. However, previous studies have not explained increased effective diffusion during this phenomenon. Here we show that enhanced interface smearing comes from a gravity induced convective motion within a thin microfluidic channel, caused by a small density difference between miscible magnetic and non-magnetic fluids. This motion resembles diffusive behavior and can be described with an effective diffusion coefficient. We explain this with a theoretical model, based on a dimensionless gravitational Rayleigh number, and verify it by numerical si…
Flexible and efficient computer-aided design tool for advanced comb-line rectangular waveguide filters
2015
A very flexible and efficient computer-aided design CAD tool, specifically suited for advanced comb-line rectangular waveguide filters, is presented in this work. The developed software tool, which makes use of a full-wave analysis technique based on the Boundary Integral-Resonant Mode Expansion method, allows loading the considered comb-line resonators with any number of radially symmetrical partial-height metallic posts. The implemented CAD tool also allows dealing with coupling windows of arbitrary cross-section, thus drastically enhancing the flexibility of the CAD process. The excitation of the analyzed components, which is performed using generalized coaxial probes, has also been inte…
