To GPU synchronize or not GPU synchronize?

Wu-chun Feng, Shucai Xiao

Proceedings of 2010 IEEE International Symposium on Circuits and Systems > 3801 - 3804

2010 IEEE International Symposium on Circuits and Systems. ISCAS 2010

The graphics processing unit (GPU) has evolved from being a fixed-function processor with programmable stages into a programmable processor with many fixed-function components that deliver massive parallelism. By modifying the GPU's stream processor to support “general-purpose computation” on the GPU (GPGPU), applications that perform massive vector operations can realize many orders-of-magnitude...

ARE YOU WHO YOU SAY YOU ARE? COMPUTER SCIENCE AND THE PROBLEM OF DIVINE SELF‐AUTHENTICATION

Andrew McFarlane

Zygon® > 57 > 1 > 84 - 108

A vital axiom of Reformed theology is that God is who God claims to be, and that he acts to “self‐authenticate” his identity to humans through the internal witness of the Holy Spirit. But how ought theologians to represent and make sense of the multiform nature of divine self‐authentication (DSA)? And can their models account for the various kinds of evidence God utilizes in acts of DSA, or explain...

Combination of graphics, uncertainty, and semantics: A survey

Yuan Gao, Muhammad Adnan Rafi

Concurrency and Computation: Practice and Experience > 34 > 7 > n/a - n/a

Graphics, uncertainty, and semantics are three approaches to building models. The combination of the three approaches is a way to develop a stronger modeling method. This article surveys the research efforts toward combining these aspects, which can be divided into two routes: One is to combine graphics and uncertainty as probabilistic graphical models and then incorporate semantics, and the other...

Towards an automatic coding of observational studies: Coding neurofeedback therapies of children with autism

Víctor R. López‐López, Lizbeth Escobedo, Leonardo Trujillo

Expert Systems > 37 > 5 > n/a - n/a

The coding of observational data is commonly used to analyse and evaluate human behaviours. The technique can help researchers inform the design and impact of, for example, an Ubicomp system by studying specific behaviours of interest. There are some tools that can alleviate the burden of observational coding, like those that help to collect and organise data, but can still be error‐prone and time‐consuming...

Qian Matteo Chen, Alberto Finzi, Toni Mancini, Igor Melatti, more

Fundamenta Informaticae > 2020 > Vol. 174, nr 3/4 > 229--258

In critical infrastructures like airports, much care has to be devoted in protecting radio communication networks from external electromagnetic interference. Protection of such mission-critical radio communication networks is usually tackled by exploiting radiogoniometers: at least three suitably deployed radiogoniometers, and a gateway gathering information from them, permit to monitor and localise...

Explaining a reverse gender gap in advanced physics and computer science course‐taking: An exploratory case study comparing Hebrew‐speaking and Arabic‐speaking high schools in Israel

Halleli Pinson, Yariv Feniger, Yael Barak

Journal of Research in Science Teaching > 57 > 8 > 1177 - 1198

In the past three decades in high‐income countries, female students have outperformed male students in most indicators of educational attainment. However, the underrepresentation of girls and women in science courses and careers, especially in physics, computer sciences, and engineering, remains persistent. What is often neglected by the vast existing literature is the role that schools, as social...

Real‐time tomographic reconstructor based on convolutional neural networks for solar observation

Fernando Sanchez Lasheras, Celestino Ordóñez, Javier Roca‐Pardiñas, Francisco Javier Cos Juez

Mathematical Methods in the Applied Sciences > 43 > 14 > 8032 - 8041

Solar observation is the branch of astronomy devoted to the study of the Sun. When the light wavefront that comes from the Sun penetrates the atmosphere, it suffers some distortions caused by optically turbulent layers that change the wavefront's shape and morphology. Therefore, in order to obtain a good‐quality image, it is necessary to correct the induced error. This is done by applying adaptive...

Extended distributive contact lattices and extended contact algebras

Tatyana Ivanova

Annals of Computer Science and Information Systems > 2020 > Vol. 21 > 69--75

The notion of contact algebra is one of the main tools in mereotopology. This paper considers a generalisation of contact algebra (called extended distributive contact lattice) and the so called extended contact algebras which extend the language of contact algebras by the predicates covering and internal connectedness.

Concept Blueprints Serving More Focused User Queries

Kurt Englmeier

Annals of Computer Science and Information Systems > 2020 > Vol. 21 > 45--48

Information Retrieval is about user queries and strategies executed by machines to find the documents that best suit the user's information need. However, this need reduced to a couple of words gives the retrieval system (IRS) a lot room for interpretation. In order to zero in on the user's need many a IRS expands the user query by implicitly adding or explicitly recommending the users further useful...
