Stress is a response that often make patients become un-stabled physically and mentally. Until recently, various types of treatment are practiced by physiologists to remedy stress problems. Virtual reality (VR) technology that is able to create an immersive 3D environment can be a better treatment therapy in comparison to existing techniques particularly to an imaginary technique. In this paper, we...
Introduction The dynamics of changes that occur in the modern world in social, economic or interpersonal terms may raise some concerns. The place and significance of human in the society of the 21st century becomes more and more radical. Some inhabitants of our globe believe in the sanctity of life, others treat people as objects. In a modern enterprise, a manager inspired by the humanistic trend...
Recently, coastal city and facilities had many damages by abnormally high waves with climate change. Especially, breakwater systems based on a caisson-type harm damages in Korea because they are located in the outside port. In order to reduce theses damages, new type breakwater systems using interlocking caisson are researched. Generally, caissons of breakwater system were constructed on crushed rock...
With the development of marine industry, the requirements for safety and reliability of deep-sea operation equipment are getting higher and higher. Experimental test is an important part of detecting the performance of deep-sea operation equipment. The deep-sea pressure environment simulation device is used as a device to detect the performance of deep-sea operation equipment. The requirements of...
Degradation due to wear, chemical deterioration or progressive embrittlement arises frequently in engineering practice. The marine environment is all the more conducive to embrittlement of offshore and subsea structures. Given the stochastic nature of the incremental damage, the important consideration is the distribution of time until the critical limit is reached. The belief that such behavior is...
The Sea-Wing7000 underwater glider, developed by the Shenyang Institute of Automation, CAS, is an instrument platform designed to glide to depths of 7000 meters for the application of deep-sea environment variables observation. Similar in structural layout to the “Sea-Wing” glider[1], to achieve these depths, The “Sea-Wing7000” using composite of carbon fiber / resin as the pressure hull. A “Sea-Wing7000”...
Word-line Batch Vth Modulation (WBVM) is proposed as a comprehensive solution for both write-hot and cold data to improve the reliability of Triple Level Cell (TLC) NAND Flash memories. For write-hot data, WBVM Vth score modulation decreases the program-disturb errors by 49% and enhances the endurance by 1.8-times of 2D-TLC NAND Flash. On the other hand, for write-cold data, WBVM BER score modulation...
We propose an on-chip bias temperature instabilities (BTI) monitor by using standard cell based unbalanced ring-oscillator (RO). The monitor consists of NAND and NOR with extremely large difference in drive strength, which enables 4.2x sensitivity to BTI compared with normal INV based RO. This originates not only from accentuation of the degraded stage with small drive strength by the dominant delay...
In this paper, we picked up epidemic diseases as factors causing division of labor and functional differentiation, and constructed an agent simulator to examine the influence. As a result, functional differentiation could be reproduced.
Emotional states involving anger, hostility, anxiety and stress have been associated with an increased risk of cardiovascular disease. Online emotion recognition has achieved little attention in the literature in comparison to offline approaches. We present both online and offline methods to identify anger based on EMG data. In the offline method, the Hilbert-Huang transform is used to extract energy...
Alternative splicing (AS) produces multiple messenger RNAs by combining different regions of the precursor transcript to produce diversity in gene products. Under stress conditions, many genes produce transcripts that are not otherwise produced during normal conditions. Plant growth and development are extensively affected by environmental stresses. In this study, we combine Differentially Alternatively...
Post-traumatic stress disorder (PTSD) is a traumatic-stressor related disorder developed by exposure to a traumatic or adverse environmental event that caused serious harm or injury. Structured interview is the only widely accepted clinical practice for PTSD diagnosis but suffers from several limitations including the stigma associated with the disease. Diagnosis of PTSD patients by analyzing speech...
Soft actuators have allowed for a variety of innovative applications, however, the mathematical modeling of soft actuators is still in its infancy. In this paper, we present a multi-cavity composite soft pneumatic actuator constitutes of multiple layers with embedded multiple air channels. The principle of operation of this actuator is comprehensively analyzed and described through building the analytical...
A kind of LLC resonant converter with voltage-doubling rectifier technology is studied in this paper. The converter has not only a general LLC half-bridge resonant converter being easy to obtain ZVS for primary side switches and ZCS for secondary side diodes, a high efficiency of this topology, but also advantages that the transformer structure is simple in which one winding is involved on its secondary...
Drop test for solder joint reliability is critical for all area arrays and perimeter-leaded surface mount semiconductor devices typically used in handheld electronic products. Joint Electron Device Engineering Council, JEDEC, published a new test standard, JESD22-B111A, to be the revision of the JESD22-B111 for board level drop test in November, 2016. The major differences between JESD22-B111 and...
A central goal of systems biology is to uncover the underlying functional architecture of the cell and study its mechanisms. To this end, large amounts of omics data are being rapidly generated, and a focus of bioinformatics research has been towards integrating these data to identify active pathways or modules under certain conditions. Many bioinformatics algorithms include optimization methods,...
Objective: Temporomandibular Disorder (TMD) is a jaw joint dysfunction characterized by various symptoms including pain in the jaw joint, facial structures, head, and muscles controlling the joint movement. In many patients TMD results in chronic pain and other related conditions. As the exact cause and cure of TMD remains unknown, individuals affected by TMD continue to experience high amount of...
In competitive energy markets, the growing adoption of renewable energy sources such as wind energy and photovoltaics causes power grid fluctuations due to the intermittency and variability in their power output. To balance the demand and generation by renewable sources conventional thermal power plants must operate with greater flexibility in the way they increase or decrease output. Furthermore,...
Aiming at the impact damage of transmission steel structure tower coating in Xinjiang, the dynamic impact mechanics behavior of transmission steel structure tower coating under simulated single particle impact was studied by automatic sphere impact tester and digital image correlation experiment measuring system. The three-dimensional morphological features of impact damage were analyzed by laser...
This paper presents the analysis and design of a boost converter with bipolar Dickson voltage multiplier. The bipolar Dickson voltage multiplier offers high gain with low stress on both capacitors and switches. Connecting bipolar Dickson cell to a boost converter yields several benefits such as an overall high static voltage gain and at the same time reduces the required inductance that ensures operation...
