For those one-dimensional thermoelectric materials with nanowire array structure fabricated with alumina film as template, its thickness is often in the range of 10 to several tens micrometers, and the conventional measurement cannot be used. The key difficulties of the thermoelectric performance measurement for nanowire array materials include two aspects: 1) How to heat the two sides of the specimen uniformly and keep the temperature difference constantly at the same time; 2) How to measure the temperature of the two sides of the specimen with the thickness of 10 to several tens micrometers. A new type heating and temperature measuring technology has been used, and it can be simply described as liquid heating and separate temperature measurement. According to this principle, a thermoelectric performance measurement system has been established.展开更多

Contemporary science is seeing a significant breakthrough and a new revolution of science and technology is beginning. The theoretical basis of the new revolution of science and technology is "state space-time", "the unity of physics and biology", "thinking motion and automatic organization of the universe" and "thinking's active control". The new revolution of science and technology takes material (microscopic particle) science, life (organic and inorganic life) science and thinking science as the fundamental sciences, takes life technology, new information technology, new material technology and new energy technology as the basis of the overall technological system, progresses in all aspects, including life technology, medicine, new material technology, new information technology, new energy technology, new robot technology, new manufacturing technology, laser technology, astronavigation technology, ocean technology, military technology, new educational technology, etc., and at the same time Qigong technology with thinking control as its core will emerge. In the era of life, thinking and Qigong technology, technology proceeds very rapidly, global society and economy develop at a high speed, and globalization is accelerated. Life, thinking and Qigong technologies feature improvement of human internal energy and quality, purify human soul, reduce material desire, and greatly reduce environmental disruption.

Initially invented to replace the need for physical data cables, Bluetooth offers users a quick and easy way to share data files over a wireless network. Traffic engineers and transportation engineering researchers have utilized the potential opportunities that exist with Bluetooth and have implemented this technology into traffic monitoring techniques. To gain a better understanding of Bluetooth sensors and how they work, a comprehensive literature search was conducted. Twenty-five articles were studied regarding case studies of Bluetooth sensor implementation for travel time measurement. Besides reviewing the literature and previous case studies, three new case studies in the State of Delaware, USA, were also conducted and carefully analyzed. The benefits and drawbacks associated with Bluetooth technology for travel time measurements have been identified in this paper. The overall conclusion of the authors is Bluetooth alone and by itself is not a proper technology for travel time measurements.
