—This paper analyzes the current status of power production safety, introduces the realization principle of intelligent working guarding system in substations, and delves into the technologies of positioning and intelligent video analysis based on ultra wideband (UWB) technology and high resolution digital spatial data of the substations. Based on the acquired data, an intelligent working moni...

Regionalism is an analytical and critical perspective which focuses on preserving special features of place and attempts to fill the vacuum in architecture. Globalization is a complex multi-stage process that causes increasing complexity of time and place, greater awareness across the global and acceleration of cross cultural interactions. Therefore, the present paper attempts to analyze global...

With rapid growth of producing high-resolution digital contents such as Full HD, 4K, and 8K movies, the demand for low cost and high throughput sharing of content files is increasing at digital content productions. In order to meet this demand, we have proposed DRIP (Distributed chunks Retrieval and Integration Procedure), a storage and retrieval mechanism for large file sharing using forward e...

The technique of the orthogonal projection of ionosphere electronic content variations for mapping total electron content (TEC) allows us to visualize ionospheric irregularities. For the reconstruction of global ionospheric characteristics, numerous global navigation satellite system (GNSS) receivers located in different regions of the Earth are used as sensors. We used dense GNSS networks in c...

Total Electron Content (TEC) is an ionospheric characteristic used to derive the signal delay imposed by the ionosphere on trans-ionospheric links and subsequently overwhelm its negative impact in accurate position determination. In this paper, an Evolutionary Algorithm (EA), and particularly a Genetic Programming (GP) based model is designed. The proposed model is based on the main factors tha...

6 [1] In this study, ionospheric solar flare effects on the total electron content (TEC) and 7 associated time rate of change (rTEC) derived from ground-based global positioning 8 system (GPS) receivers in the midday region are examined. The occurrence times and 9 locations of 11 solar flares are isolated from the 1–8 Å X-ray radiations of the 10 geosynchronous operational environmental satelli...

Supply chains have expanded rapidly over the decades, with the aim to increase productivity, lower costs and fulfil demands in emerging markets. The increasing complexity in a supply chain hinders visibility and consequently reduces one’s control over the process. Cases of disruption such as the ones faced by Ericsson have shown that a risk event occurring at one point of the supply chain can g...

Construction supply-chain management offers new approaches to reduce the cost of and increase the reliability and speed of facility construction. Supply-chain management takes a systems view of the production activities of autonomous production units (subcontractors and suppliers in construction) and seeks global optimization of these activities. Applications of supply-chain management techniqu...

A method for the removal of ionospheric effects from single-frequency non-GPS radio navigation data through the use of data collected from a single collocated dualfrequency GPS receiver is presented. The method uses a local ionosphere model to estimate the total electron content (TEC) along any line of sight that differs from the GPS satellite lines of sight. Two novel models are investigated, ...

Content-based Image Retrieval (CBIR) has become one of the most active research areas in the past few years. Most of the attention from the research has been focused on indexing techniques based on global feature distributions. However, these global distributions have limited discriminating power because they are unable to capture local image information. The use of interest points in content-b...
