In this study, we present a long term Implantable Medical Device (IMD) for continuous monitoring of physiological signals such as electrolytes, proteins, glucose, and temperature. The device consists of a small size dual band implantable antenna operating in Medical Implant Communications Service (MICS) (402 MHz–405 MHz) and Industrial, Scientific, and Medical (ISM) (2.4 GHz–2.48 GHz) bands with an...
A novel method based on cataluminescence (CTL) generated on the surface of nanosized Bi4MnO8 was proposed for direct determination of BTEX (benzene, toluene, ethyl benzene, xylenes) in air. The method showed high selectivity for BTEX at wavelength of 620 nm, satisfying activity at reaction temperature of 355°C and good stabiLity at air carrier flow rate of 125 ml/min. The Linear range of CTL intensity...
This work presents a study of the area of hybrid systems, conceptual aspects and application of methods of artificial intelligence and soft computing are considered. The main concepts of fuzzy sets and fuzzy logic are given, including the intervalar fuzzy logic. In addition, it presents a discussion of the possibilities of integrating genetic algorithms and fuzzy inference systems.
The earlier warning of electronic systems failure provided by canaries attached to them can effectively reduce system life cycle operational costs with respect to spare parts and replacement decisions. This paper presents a theoretical model for the derivation of the expected total cost per unit time in terms of the order interval and maximum allowable stock level.
The e-portfolio is a reflective tool which is in consistent with the constructive learning theory and autonomous learning by collecting students' artifacts through multi-media. In this thesis, suggestions to the use of e-portfolios are explored from the angels of teachers and learners: teachers should help learners to evaluate themselves, to acquire the knowledge of learning styles and meta-cognitive...
Based on the large span space structure of Ordos's airport extension project, a construction technique of curve pushing accumulating sliding was put forward and the principle of which was elaborated. A whole set of construction techniques was proposed, which included the design of three-directional bearing slipway and skied beams, friction-reducing technique and anti-friction materials, analog loading...
In practical application of electro-mechanical impedance (EMI) technique, the monitored structure is constantly undergoing change due to external boundary conditions and the surrounding ambience. This change, in most cases, is considered to be normal and a part of the everyday use of the structure. The aim of this paper is to examine and obtain a better understanding of practical issues that are a...
When using shield driven method to construct tunnels, mechanical properties of injecting cement paste will change at curing age. And then ground settlement will also change because of changes of mechanical properties of injecting cement paste. Based on the first line of Ningbo rail transit, this paper will discuss the effect of ground settlement caused by changes of elastic modulus and Poisson's ratio...
It is the most concerning problem of information society how quality of learning is promoted. The studying of germane cognitive load is beneficial in promoting quality of learning. To promote the learning quality of complicate cognitive task, the article discusses the defining, constraints, measuring and increasing methods of germane cognitive load in detail.
Polarization and Depolarization Current ( PDC) testing is a non-destructive dielectric testing method to determine the conductivity of insulations. It is one of the dielectric diagnostic techniques based on time domain measurement. PDC measurement technique has gained immense popularity due to its ability to assess the condition of HV insulation. PDC measurement can provide information about the conductivity...
Sensing systems for reliability prognostics are used extensively in life- and mission- critical electronics systems. They allow monitoring of reliability stresses in real time and scheduling of preventative maintenance before system failure. However, reliability prognostics systems are, in general, large and expensive and cannot be used in lower cost, small sized or portable products.
Nowadays multimedia-assisted listening assumes more and more important roles. This paper intends to explore the effectiveness and feasibility of metacognitive awareness and strategy-based approach to multimedia-assisted listening in the Chinese context. What is needed is an expansion of the current approach to engage learners in a wide range of metacognitive activities to help learners integrate the...
The chief task of public crisis prevention is to forestall crisis and reduce losses. As an important part of public governance, non-government organizations should play an active part in the prevention of public crisis in combination with their own advantages. The paper is intended to make explorations from the advantages and limitations of non-governmental organizations' participation in public crisis...
With the theory[1–4] enabled technology, we have been able to purify information from zones up to two atomic spacings regarding the evolution of the bond length, bond strength, energy density, and the energetic behavior of the localized core and valence electrons by filtering out the bulk and background information, which enabled us to identify the direction of charge flow in the catalytic reactions...
Safe, secure, reliable, and sustainable energy supply is vital for advanced and industrialized life styles. To meet growing energy demand there is interest in longer-term operation for the existing nuclear power plant fleet and enhancing capabilities in new build. There is increasing use of condition-based maintenance for active components and growing interest in deploying on-line monitoring instead...
After analyzing launching characters of ventilation system, water cycling system and circuit supply system in large warehouse systems, PHM (Prognostics and Health Management) technology applications in large warehouse systems is discussed in terms of maintainability and supportability, and a framework of maintenance support mode for large warehouse systems is proposed based on PHM. The foundation...
In the present study we investigated the influence of the sensory modality of information on the perceived roughness of unfamiliar textures. Subjects were instructed to judge the roughness of embossed dot patterns with varying inter-dot spacing in a visual, haptic or a visual-haptic combined information condition. Our results indicate that the relationship of inter-dot spacing and roughness perception...
Real time assay of protein secretion from living single cells was realized by coupling total internal reflection fluorescence (TIRF) microscopy observation and an optically optimized microwell array device. This system was based on a sandwich immunosorbent assay. Individual cells were cultured on an inverted microscope in microwell arrays fabricated of an amorphous fluoropolymer, CYTOP, to be monitored...
To verify the validity of oil analysis for heavy diesel engine condition monitoring, the lubricating oil were sampled from the lubricating system of the domestic diesel engines, and then were tested by oil analysis (including contamination detection, periodic sampling test and ferrography technology). The results showed that oil analysis could monitor the lubricating oil contamination and mechanical...
Geomorphical environment is the most important natural factors on the formation of ocean cultural landscape. It directly impacts on solar radiation, material sources and other natural elements, and it has also affected the frequency, intensity and spatial pattern of human activity. Through analyzing the adoption of geomorphical environment on the formation of coastal cultural resources, the author...
