GSaaS: A Service to Cloudify and Schedule GPUs
2018
Cloud technology is an attractive infrastructure solution that provides customers with an almost unlimited on-demand computational capacity using a pay-per-use approach, and allows data centers to increase their energy and economic savings by adopting a virtualized resource sharing model. However, resources such as graphics processing units (GPUs), have not been fully adapted to this model. Although, general-purpose computing on graphics processing units (GPGPU) is becoming more and more popular, cloud providers lack of flexibility to manage accelerators, because of the extended use of peripheral component interconnect (PCI) passthrough techniques to attach GPUs to virtual machines (VMs). F…
Monitoring few molecular binding events in scalable confined aqueous compartments by raster image correlation spectroscopy (CADRICS)
2016
The assembly of scalable liquid compartments for binding assays in array formats constitutes a topic of fundamental importance in life sciences. This challenge can be addressed by mimicking the structure of cellular compartments with biological native conditions. Here, inkjet printing is employed to develop up to hundreds of picoliter aqueous droplet arrays stabilized by oil-confinement with mild surfactants (Tween-20). The aqueous environments constitute specialized compartments in which biomolecules may exploit their function and a wide range of molecular interactions can be quantitatively investigated. Raster Image Correlation Spectroscopy (RICS) is employed to monitor in each compartmen…
QuBiLS-MAS, open source multi-platform software for atom- and bond-based topological (2D) and chiral (2.5D) algebraic molecular descriptors computati…
2017
Background In previous reports, Marrero-Ponce et al. proposed algebraic formalisms for characterizing topological (2D) and chiral (2.5D) molecular features through atom- and bond-based ToMoCoMD-CARDD (acronym for Topological Molecular Computational Design-Computer Aided Rational Drug Design) molecular descriptors. These MDs codify molecular information based on the bilinear, quadratic and linear algebraic forms and the graph-theoretical electronic-density and edge-adjacency matrices in order to consider atom- and bond-based relations, respectively. These MDs have been successfully applied in the screening of chemical compounds of different therapeutic applications ranging from antimalarials…
GPU-Based Optimisation of 3D Sensor Placement Considering Redundancy, Range and Field of View
2020
This paper presents a novel and efficient solution for the 3D sensor placement problem based on GPU programming and massive parallelisation. Compared to prior art using gradient-search and mixed-integer based approaches, the method presented in this paper returns optimal or good results in a fraction of the time compared to previous approaches. The presented method allows for redundancy, i.e. requiring selected sub-volumes to be covered by at least n sensors. The presented results are for 3D sensors which have a visible volume represented by cones, but the method can easily be extended to work with sensors having other range and field of view shapes, such as 2D cameras and lidars.
An Efficient Cooperative Smearing Technique for Degraded Historical Documents Images Segmentation
2020
Segmentation is one of the critical steps in historical document image analysis systems that determines the quality of the search, understanding, recognition and interpretation processes. It allows isolating the objects to be considered and separating the regions of interest (paragraphs, lines, words and characters) from other entities (figures, graphs, tables, etc.). This stage follows the thresholding, which aims to improve the quality of the document and to extract its background from its foreground, also for detecting and correcting the skew that leads to redress the document. Here, a hybrid method is proposed in order to locate words and characters in both handwritten and printed docu…
University Teachers as Developers of Technology-Enhanced Teaching—Do Beliefs Matter?
2019
Previous research has identified a well-established link between teachers' beliefs and the practical implications of technology-enhanced learning (TEL). Until recently, there have been few studies ...
Translating cultures, cultures in translation
2021
Among its several definitions, translation can be understood as ‘a rendering from one language into another’, probably the most immediate sense, as ‘a change to a different substance, form, or appe...
How to study bureaucracies ethnographically?
2019
We propose a short epistemological and methodological reflection on the challenges of doing ethnographical research on public services (‘bureaucracies’) from the inside. We start from the recognition of the double face of bureaucracy, as a form of domination and oppression as well as of protection and liberation, and all the ambivalences this dialectic entails. We argue that, in classical Malinowskian fashion, the anthropology of bureaucracy should take bureaucrat as the ‘natives’, and acknowledge their agency. This means adopting basic anthropological postures: the natives (i.e. the bureaucrats) must have good reasons for their seemingly ‘absurd’ (or arbitrary) practices, once you underst…
Suffering as an anchor of critique. The place of critique in critical discourse studies
2017
If we engage in reflection on standards of critique, we are entering the terrain of metaethics, or the question of which ethical standards we should accept. The question is not only, in the sense o...
Development of Professional Identity During Teacher's Practice
2016
Abstract The article focuses on issues of the development of professional identity of English teachers-to-be in Latvia. This development is an ongoing process which starts during teacher education. The article aims to examine emerging professional identity and how reflective self-evaluation during teacher's practice done with the help of reflective activities facilitates professional development of student teachers. Specific attention is paid to the self-reflection on teacher's practice experiences done with the help of the EPOSTL. It is also concerned with the ways how university can improve student's awareness of their identity. The conducted case study involved questionnaire, content ana…
