This research identified the occurrence of Medium-Scale Traveling Ionospheric disturbances (MSTIDs) during the ascending solar activity year 2010–2013 using the All-Sky Imager (ASI) mounted on Sirindhorn Observatory, Chiang Mai Thailand (18.8° N, 98.9° E, 13° dip latitude) to study the mechanism of the generation of irregularities in the ionosphere at low magnetic latitudes. The occurrences of MSTIDs...
This paper presents a scalable transmit phase array operating at 140 GHz which employs a local PLL reference generation system. Unlike traditional CMOS phase arrays, this enables the array to be formed over multiple chips while avoiding the challenges of distributing mm-wave signals between them. The prototype chip consumes 131 mW of power and occupies 1.95 mm2 of chip area when implemented in 65...
Objective: NPQ scale and soft tissue tension were used as the main evaluations to observe the clinical efficacy of acupuncture treatment based on the concept of heart and gall bladder from TCM aspect for Neck Type of Cervical Spondylosis(NTCS). Methods: 73 cases meeting the inclusion criteria of NTCS were divided into the treatment group and control group by using the randomized controlled clinical...
Since reform and opening up, in China, economy is developed rapidly, while economic system is increasingly build up sophisticated. But as nowadays we are promoting green and efficiency, part of the manufacturing enterprises in China are still in need of improvement. The operation of green supply chain is limited by many factors, faced a lot of uncertainty, so the manufacturing industry is facing a...
Study on physical load provides astronauts with important manned space ergonomics guidance. In this paper, quantitative measurement and evaluation methods of physical load were commented, the advantages, disadvantages and improvements of physiological methods, biochemical methods, energy metabolism and subjective methods were analyzed, the application status and future trends of astronaut physical...
High-tech industry acts as a strong radiating role in national economy. This paper builds an index system to evaluate the innovative capacity of high-tech industry after literature review. Then it applies Factor Analysis and Cluster Analysis to empirically study the innovative capacity of high-tech industry in 11 provinces and municipalities of East China, and offers proposals to solve existing inadequacies.
The screening problem, namely, observing the screening variable rather than directly observing the performance variable, has been studied for a long time. However, inspection error which frequently occurs in a screening process has not been investigated in previous research. In this paper, we proposed a two-stage single screening procedure under one-sided specification in order to gain insight into...
Getting an objective, scientific and general ecosystem health assessment is the precondition and foundation of watershed management. This paper reviewed the concept and content of the NWA assessment system (natural constraint factor-watershed health indicator factor-anthropogenic disturbance factor" assessment system), and selected twelve indicators and constructed the model based on the character...
Event related potential (ERP) is a kind of cognitive electroencephalogram (EEG) signal, which are directly related with cognitive task and average across EEG. However, the plentiful oscillatory activities evoked by various stimuli as well modulated by different cognitive tasks or behavioral events will be attenuated in the course of average. With respect to every EEG trials caused by the same stimulus,...
Evaluation and warning of human resource management risk can reduce potential risk in engineering management. On the basis of consulting a lot of relevant reference and investigating projects, it was built that evaluation index system and warning model of project human resource management with fuzzy comprehensive evaluation and classification and genetic analysis of project human resource management...
