Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...

NTT DOCOMO Technical Journal Vol. 10 No. 4 *1 MIMO: A signal transmission technology that uses multiple antennas at both the transmitter and receiver to perform spatial multiplexing and improve communication quality and spectral efficiency. *2 Beam forming: A method for improving signal separation performance at the receiving side by doing precoding on the transmitting side based on channel dat...

Air pollution is one of the major issues about the diesel engines in todays' world. It is a special concern in those areas that have difficulty meeting health-based outdoor air quality standards. Natural gas has low emission and resource abundance and also conventional compression ignition engine can be easily converted to a dual fuel mode to use natural gas as main fuel and diesel as pilot ...

Existing algorithms for learning Boolean networks (BNs) have time complexities of at least O(N · n), where n is the number of variables, N is the number of samples and k is the number of inputs in Boolean functions. Some recent studies propose more efficient methods with O(N · n) time complexities. However, these methods can only be used to learn monotonic BNs, and their performances are not sa...

Open-framework chalcogenides are potential electrode materials for sodium-ion batteries (SIBs) due to their architectures with fast-ion conductivity. Herein, we report on the successful synthesis of open-framework Cu-Ge-based chalcogenides [Cu8Ge6Se19](C5H12N)6 (CGSe) and the research of their energy storage application as SIB anodes for the first time. As a result, the CGSe anode exhibited goo...

Aim. The aim of the article is to look for an answer question whether it worthwhile deal only with happiness and leave exploration quality life as something which not viable, or if makes sense both phenomena. If so, what relationship between them? At same time, we ask ourselves are perceived equally by people therefore interchangeable. Results. also confirmed measuring number published articles...

By functionalizing the surfaces of ZnO nanobelts (NBs) with a thin self-assembled molecular layer, the electrical and optoelectronic performances of a single NB-based device are drastically improved. For a single NB-based device, due to energy band tuning and surface modification, the conductance was enhanced by 6 orders of magnitude upon functionalization; a coating molecule layer has changed ...

Three diierent algorithms for qualitative obstacle detection are presented in this paper. Each one is based on diierent assumptions. The rst two algorithms are aimed at yes/no obstacle detection without indicating which points are obstacles. They have the advantage of fast determination of the existence of obstacles in a scene based on the solvability of a linear system. The rst algorithm uses ...
