UML Artefacts for a Blockchain-enabled Platform for Fairtrade

2021

Fairtrade-certified products have successfully entered the mainstream distribution channels mostly in developed countries, and these products are now sold in famous supermarket chains. Nonetheless, the packaging and labeling of products as “Fairtrade” commands premium pricing in the marketplace. How much of this, however, is valid and justified? Despite the reputable certification mechanisms for quality assurance, mass media reports suggest that much of the “surplus value” goes to the accreditation agencies themselves instead of the producers. This article proposes an agenda to set this right with a blockchain platform that provides “trust-free” assurances of verifiable labeling. Using an A…

Towards the definitive evaluation framework for cross-platform app development approaches

2019

Abstract Mobile app development is hindered by device fragmentation and vendor-specific modifications. Boundaries between devices blur with PC-tablet hybrids on the one side and wearables on the other. Future apps need to support a host of app-enabled devices with differing capabilities, along with their software ecosystems. Prior work on cross-platform app development concerned concepts and prototypes, and compared approaches that target smartphones. To aid choosing an appropriate framework and to support the scientific assessment of approaches, an up-to-date comparison framework is needed. Extending work on a holistic, weighted set of assessment criteria, we propose what could become the …

Trusted Computing and DRM

2015

Trusted Computing is a special branch of computer security. One branch of computer security involves protection of systems against external attacks. In that branch we include all methods that are used by system owners against external attackers, for example Firewalls, IDS, IPS etc. In all those cases the system owner installs software that uses its own means to determine if a remote user is malicious and terminates the attack. (Such means can be very simple such as detecting signatures of attacks or very complex such as machine learning and detecting anomalies in the usage pattern of the remote user). Another branch of attacks requires protection by the system owner against internal users. …

Generating App Product Lines in a Model-Driven Cross-Platform Development Approach

2016

Within software product lines (SPL) similar software products are created based on common features. We applied this versatile approach to cross-platform app development by extending the domain-specific language (DSL) of an established model-driven development framework. The goal was to support the formulation of coherent building blocks of business use cases, referred to as workflow elements. While the former implementation already abstracted from technical details and provided the possibility to reuse low level features, it now enables to build business apps by combining coherent, self-contained workflow elements. Providing this support on the language level facilitates reusable component-…

A Conversational Agent Based on a Conceptual Interpretation of a Data Driven Semantic Space

2005

In this work we propose an interpretation of the LSA framework which leads to a data-driven “conceptual” space creation suitable for an “intuitive” conversational agent. The proposed approach allows overcoming the limitations of traditional, rule-based, chat-bots, leading to a more natural dialogue.

Marginal bone loss in relation to platform switching implant insertion depth: an update

2011

A review is made, analyzing marginal bone loss in relation to the depth of implant insertion with platform switching, according to the position of the neck (supracrestal, crestal or subcrestal), and evaluating survival of the implants. A PubMed search was made of the studies in animals and humans published between 2005 and 2011, specifying platform insertion depth (supracrestal, crestal or subcrestal) and registering marginal bone loss from the time of prosthetic restoration to the end of follow-up (minimum 6 months). A total of 30 studies were included. The bone loss associated with implants placed at supracrestal level was slightly smaller than in the case of implants placed at subcrestal…

Progressive Web Apps for the Unified Development of Mobile Applications

2018

Progressive Web Apps (PWAs) allow for web applications to be developed in an offline-first approach. While Web apps traditionally did not properly function without an Internet connection, PWAs enable them to be downloaded, installed and used offline on various systems, including mobile devices and personal computers. We present an introduction to the state-of-art in research and practice. Based on this, we discuss various underlying concepts and technologies. Then, we scrutinize and compare PWAs against cross-platform app development approaches on both technical and overarching aspects. A list of suggestions for future research is also presented. We urge academia to keep up with the latest …

A hardware skin-segmentation IP for vision based smart ADAS through an FPGA prototyping

2017

International audience; In this paper we presents a platform based design approach for fast HW/SW embedded smart Advanced Driver Assistant System (ADAS) design and prototyping. Then, we share our experience in designing and prototyping a HW/SW vision based smart embedded system as an ADAS that helps to increase the safety of car's drivers. We present a physical prototype of the vision ADAS based on a Zynq FPGA. The system detects the fatigue state of the driver by monitoring the eyes closure and generates a real-time alert. A new HW/SW codesign skin segmentation step to locate the eyes/face is proposed. Our presented new approach migrates the skin segmentation step from processing system (S…

Redzes ietekme uz stāju

2017

Maģistra darbs ir uzrakstīts angļu valodā uz 45 lapām. Tas satur 28 attēlus un 40 literatūras atsauces. Darba mērķis bija izvērtēt optometriskās ārstēšanas ietekmi uz stājas izmaiņām. 11 pacientiem tika veikti mērījumi ar datorizētu stabilometrijas platformu pirms un pēc redzes treniņu veikšanas. Pacientam stāvot ar atvērtām acīm, pēc redzes treniņiem svara sadalījums bija sabalansētāks priekšēji-mugurējās ass virzienā, spiediena centrs nobīdījās tuvāk teorētiskajam centram, kā arī svārstību ātrums, amplitūda un laukums samazinājās. Pacientam stāvot ar aizvērtām acīm, nenovēroja nozīmīgas izmaiņas pirms un pēc ārstēšanas. Līdz ar to, redzes kvalitātes uzlabošana var tieši ietekmēt pacienta …
