Recent research focused on improving the vehicle-to-vehicle communication (V2V) based on the 5G technology. The V2V application is important because it will reduce the risk of accidents up to 70%-80%, improve traffic management, reduce congestion, and improve fuel consumption. Autonomous vehicles applications require a high bandwidth transmission channel where the 5G communication channel would be a reliable solution to support this disruptive technology. The dedicated short-range communications (DSRC), which is characterized with a frequency bandwidth of 5.9 gigahertz (GHz) (4G spectrum), was used as vehicular connectivity with a bandwidth of up to 200 megabytes per second (mb/s) and limited capacity. The 5G band can support connected multiple autonomous vehicles with high data rates and large bandwidth. In this study, the 5G communication channel is considered as vehicular connectivity with high bandwidth in the millimeter waves spectrum range. The quality of 5G wireless communication channels between connected vehicles possibly be affected by weather conditions such as rain, snow, fog, dust, and sand. In this paper, we estimate the effect of dust and sand on the propagation of millimeter waves. The Mie model is used to investigate the effect of dust and sand storms on the propagating mm-waves. The effect of dust and sand on the communication path loss of DSRC and 5G frequency band is investigated in the case of urban freeway and rural highway settings. Results show that the attenuation of dust and sand is changed when the particle size of sand, frequency of propagating wave, and concentration of dust are changed. Finally, the new model of link margin is created to estimate the effect of dust and sand on DSCR (5.9 GHz) and 5G (28 GHz) communication path loss. © 2021, CC BY.

IEEE int.rnational Conference on Information Reuse and int.gration (IRI)

作者： Othusitse S.D. Phefo Naledi Kefitiley Hlomani Hlomani Department of Computer Science and Software Engineering Botswana International University of Science and Technology Dept. of Comput. Sci. & Software Eng. Botswana Int. Univ. of Sci. & Technol. Botswana

Ontologies are reusable artifacts within the Software Engineering filed that are a pillar of the Semantic Web. Created in a different context, they can be adapted and applied in another context. This paper endeavors to develop a knowledge base in the form of an ontology that formalizes all aspects to do with culture and thus contribute to the preservation and dissemination of cultural knowledge. Written in the context of a small African country (Botswana), the ontology is expected to be generic enough to be adaptable and reusable in the global context. Culture is the characteristics and knowledge of a particular group of people, defined by everything from language, livelihoods, religion, traditional medicine, cuisine, social habits, music and arts. Culture is transmitted orally from father to son, mother to daughter or teacher to a student. However, this knowledge is gradually lost as many young people migrate to popular culture. The absence of tools and technologies that aide in the preservation and dissemination of cultural knowledge lead to the gradual loss of cultural valuable information that could be useful for tourism, and learning. Information currently representing elements that define culture is dispersed, heterogeneous, disjoint.d, in varying stages of formalization and digitization, and distributed in collections of different memory organizations at different locations. As a solution, this paper int.oduces ontologies to formulate an efficient way to preserve and represent cultural knowledge. The benefits of the cultural ontology include, reuse, sharing, and portability of knowledge across platforms. Overall, the cultural knowledge ontology leads to a better understanding of concepts in the cultural domain and to a more effective and efficient way of handling information about concepts in the cultural knowledge domain.

IEEE int.rnational Conference on Image Processing

作者： Hajime Nobuhara Kaoru Hirota Barnabas Bede Department of Computer Int. and System Sci Tokyo Institute of Technology Yokohama Japan Department of Mechanical and System Engineering Budapest Tech Budapest Hungary

A wavelet transformation based on max-plus algebra is proposed, where analysis and synthesis operations are defined by max (or min) and standard sum and they treat with 9 channel multi resolution images. The proposed wavelets especially can reserve edge information on compressed images due to the non-linear operations (max and min); therefore, they are efficient for the compression of predictive frames used in video compression and reconstruction. Through video compression and reconstruction experiments using standard video database, it is confirmed that effectiveness of the proposed wavelets.

ISBN: (纸本)0780366980

TiO/sub 2/ thin films doped with Fe have been prepared by using the sol-gel process on silicon substrates. A metal-organic precursor solution for coating silicon substrates was synthesized using a Ti alkoxide derivative iron salt and isopropanol as a solvent. Acetylacetone was used as an inhibitor of derivative iron hydrolysis-condensation reactions. The structure of the films was investigated by X-ray diffraction and Raman scattering analysis. The electrical characterization of the films is reported.
