Tactile graphics are widely used for blind people to access visual information such as maps, diagrams, and graphs and so on. Tactile graphics are usually produced by sighted people, but some of the blind people want to produce tactile graphics by themselves to express their ideas or opinions. A special writing utensil, called a raise-writer, is used when a blind person draw tactile graphics alone...
The main theme of this paper is summarizing the results on examining regularity of functional equations with computer algebra systems. These methods can be found in the PhD thesis and partially in some articles of the author. Additionally it deals with some other applications of CAS. There were used Maple(ver 15.0) and Sage(several versions) systems.
In connection with investigations related to mathability and to applications of computer assisted methods for studying mathematical problems, an animation of the m-convex hull of finite sets of points on the Cartesian plane is presented.
This paper reports the experience of running a professional development workshop on advanced computing technologies for high and middle school computer teachers. The workshop introduced the teachers to new trends in computing technologies to be applied in the classroom. Thirty-two teachers took part in the workshop and benefited from its content. The workshop covered four different hot computing topics,...
Most computer programs are written using either or both 32- and 64-bit floating-point formats (FP32 and FP64). To save memory space, improve the computation speed, and improve energy efficiency by eliminating waste bit data in floating-point data, we need reduced-precision formats that can represent various and lower floating-point precisions. This paper proposes the implementation of reduced-precision...
The item-based collaborative filtering (CF) is one of the most successful approaches utilized by the recommendation systems. The basic concept behind it is to recommend those items to users which are similar to other items that these users have been interested in recently. This paper proposes a hybrid method that integrates user trust relations with item-based CF. This is achieved by incorporating...
By considering the fuzzy collaborative clustering, in this paper we investigate the ranking problem of factor granules, where the factor granule is composed by the patterns, the factors and the factor-induced information. Since the ideology of TOPSIS method is applied to obtain the finial ranking result, a referential factor granule is pre-provided. The collaborative information, i.e., the partition...
This paper illustrates the posture effect on Ultra High Frequency (UHF) RFID tag detection. The originality is about the polarization characteristic of passive tag and reader antennas. Different orientation of the passive tag could make the polarization loss distinct, resulting in the variation of the Received Signal Strength Indication (RSSI), for instance, placed in horizontal and vertical orientation,...
We consider the problem of finding the capacity of noisy networks under the presence of Byzantine adversaries, modeled by a joint compound channel and arbitrarily varying channel (AVC) model. This extends our earlier work which considers these models only in isolation. The motivation for this setup is that typically the adversary first selects an arbitrary subset of edges from the network and then...
Web-based service-oriented grid computing refers to a distributed computing system comprising a collection of interconnected and virtual computers that provides web-based services via the Internet. These services are based on Service Level Agreements (SLAs) established by negotiation between service providers and consumers. SLAs are contractual obligations that define the mutually agreed understandings...
Service-dominant logic, called S-D logic, proposed a new thought oftheoretical foundation for service economy from a service centricviewpoint, but basic terms and their relationship are not representedin technical form. We first formalize S-D logic in a mathematical form. In addition to the terms that have already been introduced in S-D logic, we define terms of 'capability' and 'potential'. These...
In this work, we propose to use the SSN ontology to manage the sensor information in an intelligent transportation architecture. The system performs the automatic traffic light settings allowing to predict and avoid traffic accidents and the routing optimization.
Most of all organizations try to get more benefit by gathering and analyzing various data. These systems work well in profit-making organizations especially, In recent year, permanent voluntary organizations such as universities become to be active in order to know themselves. However, temporary voluntary organizations hardly have any such systems. Therefore, such organizations can not always make...
In this paper, we propose a new facial landmarks detection method based on deep learning with facial contour and facial components constraints. The proposed deep convolutional neural networks (DCNNs) for facial landmark detection consists of two deep networks: one DCNN is to detect landmarks constrained on the facial contour and the other is to detect landmarks constrained on facial components. A...
Tracking fish in their natural environment is an important aspect of marine ecosystem research. However, real-world fish tracking is challenging due to unconstrained environments and complex scenarios. The purpose of this study is to develop a sparse sample collection and representation method (SSCR) based on the compressive sensing concept for fish tracking. The SSCR consists of sample collection...
It was investigational on the basis of the considered existent methods, that the task of exposure of optimal recovery scheme answers the mathematical task of BIB-schemes. In the process of work the recovery scheme was worked out on the basis of BIB-schemes, which works for the greater number of the damaged computers, what other existent charts. Recovery scheme of distributed system that guarantees...
Low-power embedded platforms are widely used in various data collection scenarios to capture physical world phenomena in micro-scale. Given that many applications require long operation times, it is important for nodes to employ various schemes to maximize their lifetime. Within the sensor network research community, schemes such as low-power listening (LPL) and low-power probing (LPP) have been actively...
Flowcharts have been used in problem diagnosis for a long time because of their effectiveness during process representation. However, with time, diagnostic flowcharts can become unmanageably complex and incomprehensible, thus leading to longer decision paths. A lengthy decision path also implies a time consuming diagnosis process while at the same time being boring to end users utilizing systems containing...
‘Ecole-Numerique’ or Digital Schooling has become an emerging trend for primary schooling worldwide. This paper attempts to assess the readiness of educators and schools in the migration from “Informatique” to “ÉcoleNumerique” for young learners at primary levels. A case study was drawn from two french private schools X and Y in Mauritius. To achieve this aim, the TAM model was adapted as guideline...
