Maza uzņēmuma IT infrastruktūras pilnveidošana
2017
Kvalifikācijas darba mērķis ir izpētīt maza uzņēmuma IT infrastruktūru, piedāvāt un ieviest risinājumus, kas uzlabotu tās pārskatāmību un pārvaldību. Šī mērķa sasniegšanai uzņēmumā tika ieviesti sekojoši risinājumi - VMware virtualizācijas platforma un Ubuntu Landscape centralizētās vadības sistēma, kā arī uzlabotas iespējas veikt rezerves kopiju veidošanu un uzņēmuma sistēmu pārraudzību. Darba rezultātā sasniegtais samazināja laika un darba apjomu, kas nepieciešams uzņēmuma IT infrastruktūras uzturēšanai.
Virtualizācijas iespējas datorklases ierīkošanā skolā
2017
Darbā tiek apskatīta virtualizācijas priekšrocības un salīdzinātas virtualizācijas iespējas.. Teorētiski tiek izpētīta darbstacijas virtualizācija un nepieciešamie elementi, lai tā sekmīgi varētu notikt. Īpaši tiek meklēti risinājumi, kas varētu tikt izmantoti datorklases ierīkošanai skolā, un būtu salīdzinoši lēti. Praktiskajā daļā tiek ieviesta sistēma, izmantojot brīvpieejas programmatūru Linux Ubuntu 16.04.2 serveri, KVM virtualizāciju rīkus, kas apkalpo virtuālās mašīnas un savienojumu starp klientu un serveri.
Leveraging a Wiki to EnhanceVirtual Collaboration in the Emergency Domain
2008
In a crisis situation, critical success factors include good preparedness, the availability of trustworthy information and reliable people, and the responders' ability to improvise with the available, functioning tools. Wikis can be used as collaborative group support systems to support these activities, especially for communities of practice that must operate as high reliability organizations. The advantages of using a wiki are especially beneficial in volatile environments, such as those in the emergency domain, where critical real-time decision making is required. An international wiki emergenciWiki.org - has been created and is being used by both practitioners and academics. The conclus…
Ant Colony Models for a Virtual Educational Environment Based on a Multi-Agent System
2008
We have designed a virtual learning environment where students interact through their computers and with the software agents in order to achieve a common educational goal. The Multi-Agent System (MAS) consisting of autonomous, cognitive and social agents communicating by messages is used to provide a group decision support system for the learning environment. Learning objects are distributed in a network and have different weights in function of their relevance to a specific educational goal. The relevance of a learning object can change in time; it is affected by students', agents' and teachers' evaluation. We have used an ant colony behavior model for the agents that play the role of a tu…
The master’s dissertation viva by video conference: strategies and best practices
2019
Durante la última década, se han publicado numerosos estudios sobre el proceso de elaboración y evaluación de los trabajos de fin de máster (TFM) (Da Cunha, 2016; García & Martínez-Clares, 2012; González-Calero & Turégano, 2011), sobre las fases de tutorización y acompañamiento al estudiante (Flores, Martínez, Martínez López, Pascual, & Sanz, 2013) y sobre las competencias a adquirir tras su finalización (Cabrera, Sangrà & Rodera, 2012; Serrano & Pontes, 2015; Viejo & Ortega Ruiz, 2018). Sin embargo, no resultan tan evidentes las investigaciones que analizan la fase de preparación y defensa pública de estos trabajos, siendo, sin embargo, la que genera más incomodidad entre el estudiantado. …
A facially driven complete-mouth rehabilitation with ultrathin CAD-CAM composite resin veneers for a patient with severe tooth wear: A minimally inva…
2020
Abstract The development of technologies that include face scanning and dental software has improved workflows in dentistry. Digital files make it possible to create a 3-dimensional virtual image of the patient that helps the clinician plan treatment and make decisions, reducing uncertainty and improving communication. This report describes the complete-mouth rehabilitation of a patient with severe tooth wear. The treatment adopted a minimal intervention approach, applying adhesive veneers in areas where the tooth structure was affected and used a computer-aided design and computer-aided manufacturing (CAD-CAM) workflow to prepare nanoceramic composite resin materials with a high filler loa…
Cargo-Cult Containerization : A Critical View of Containers in Modern Software Development
2022
Software is increasingly developed and deployed using containers. While the concept of a container is conceptually straightforward, there are various issues to be considered while using them, ranging from technical details inside containers to the orchestration of containers that jointly form a meaningful application. In recent years, the use of containers has become so prevalent that developers have a tendency to resort to cargo-cult containerization - ritual adherence to the use of containers just because so many others are doing the same thing. In this paper, we study advantages and downsides of containers in modern-day software development. We foresee the use of containers to spread int…
Development of virtual money as a response to the imperfections of the modern financial system
2018
This article attempts to answer the question what factors led to the establishment of bitcoin - the first digital money which is completely private and independent of central banks or any other supervisory authority. In the article enumerated many factors, but indicated the most important which was the global financial crisis in 2008. Additionally, the article presents the genesis of bitcoin, the comparison to classic money and its unique features which are also the reasons for its unprecedented popularity.
Diagrammatic Gestures. Cognition, Mathematics, and Semiotics.
2021
here are words having an extraordinary evocative power. This is precisely the case of “Diagram” and “Gesture”. The frst term covers an interconnected network of concepts like “graph”, “schema”, “form”, “model”, “arrow”, and so on... And the same can be said of the second one: just think, for example, of the ideas of “movement”, “bodily action”, “practical activity” or, more generally, of “doing”. Accounting for them has been, over the last 50 years, the aim of signifcant portions of the work conduction in philosophy (Deleuze, Foucault, Merleau-Ponty), mathematics (Grothendieck, Lawvere, Thom), semiotics (Peirce), and theoretical linguistics (Culioli, Langacker, Pottier). The present issue a…
Atom- and Bond-Based 2D TOMOCOMD-CARDD Approach and Ligand-Based Virtual Screening for the Drug Discovery of New Tyrosinase Inhibitors
2008
Two-dimensional atom- and bond-based TOMOCOMD-CARDD descriptors and linear discriminant analysis (LDA) are used in this report to perform a quantitative structure-activity relationship (QSAR) study of tyrosinase-inhibitory activity. A database of inhibitors of the enzyme is collected for this study, within 246 highly dissimilar molecules presenting antityrosinase activity. In total, 7 discriminant functions are obtained by using the whole set of atom- and bond-based 2D indices. All the LDA-based QSAR models show accuracies above 90% in the training set and values of the Matthews correlation coefficient (C) varying from 0.85 to 0.90. The external validation set shows globally good classifica…
