Employing RFID for an Equipment Management System via Wireless Sensor Network

This paper is mainly in combination with RFID to construct a set of power system equipment remote control, used first on the reader tags received after the use of Visual Basic in order to determine the signal and then transmits the signal via the RS232 cable to control circuit 8051 to control the instrument power switch. The topic is written in the Visual Basic RFID and uses features, such as personnel control systems, and access control systems, which are derived from the time of access control systems, several instrument control systems, and uses records stored in the form of functions, where the other circuit transmits signals to Visual Basic 8051, and then, by 8051, controls the instrument power switch

A novel test of gravity via black hole eikonal correspondence

When adopted in black hole spacetimes, geometric-optics approximations imply a mapping between the quasinormal mode (QNM) spectrum of black holes in the eikonal limit and black hole images. In particular, the real part and the imaginary part of eikonal QNM frequencies are associated with the apparent size and the detailed structure of the ring images, respectively. This correspondence could be violated when going beyond general relativity. We propose a novel method to test the eikonal correspondence via the comparison of two sets of observables from a nonrotating black hole, one extracted from QNM spectra and the other from the lensed photon rings on the image plane. Specifically, the photon ring observables robustly capture the information of the black hole spacetime itself regardless of the surrounding emission models. Therefore, the proposed test of eikonal correspondence can be validated in quite broad scenarios.Comment: 9 pages, 2 figures. Matching published versio

Metal-Organic Framework Synthesis System Based on Fuzzy Predictive Control via Network Transmission

The purpose of this study is to construct metal-organic framework (MOF) synthesis heating systems based on fuzzy method for monitoring and automatic control. In this study, the temperature sensing module for measurements sensed values that it through a wireless ZigBee chips and wired DAQ device for real-time data transmission. Because MOF synthesis, often due to different modes of heating or heating instability caused by its nucleation and crystal growth rate, is an important influence, leading to different crystallinity, the use of fuzzy theory to predict the temperature parameter and instant heating MOF synthesis parameters can be adjusted to improve the accuracy of the system. The research system to RS-232 interface module for infrared emission control packets issued and automated control of the furnace through the infrared receiver module. This study is based on a terminal interface window of Visual Basic programming and LabView graphical diagram for control system design. Finally, this research, through a number of experiments to validate the use of fuzzy system development methods and networks, can improve the accuracy of the reaction efficiency MOF sensing and control the heating system

HPV Knowledge, Attitudes, and Vaccination Among Hispanic/Latino College Students in the USA

This study evaluated Human Papillomavirus-related knowledge and attitudes, vaccination practices, and explored associated factors among Hispanic/Latino college students in the United States of America. Using a self-administered survey, a descriptive, cross-sectional quantitative study was conducted in 2018 at colleges and universities in the United States of America. Our results indicate that Hispanic/Latino college students had a low level of HPV-related knowledge, a moderately positive attitude, and a moderate rate of HPV vaccination. Students who were in a health-related major, married/divorced, and had health insurance had greater knowledge and more positive attitudes towards HPV and its vaccines. This study is important due to the disproportionate high rate of HPV associated cervical cancers among Hispanic/Latinos when compared to other races and ethnicities. Our findings will inform the development of innovative intervention to promote HPV vaccination uptake across educational institutions

QoS routing with link stability in mobile ad hoc networks

Abstract. In this paper, in accordance with requirements of different users and supplying effective usage of limited network resources, we propose a stable QoS routing mechanism to determine a guaranteed route suited for mobile ad hoc wireless networks. The manner exploits the received signal strength (RSS) techniques to estimate the distance and the signal change of the velocity to evaluate the breakaway. To ensure the QoS it chooses a steady path from the source to the destination and tries to reserve the bandwidth. Ultimately, it is clear to find that the performance never decrease even the growth of the overhead and the movement of users via the simulated by ns-2. Introduction Mobile Ad Hoc Wireless Networks (MANET), also called the Ad hoc network, is lots of moving nodes (mobile hosts) communicating with their adjacent mobile node by radio wave. Every node can contact each other without existence infrastructural network. In the Ad hoc network, it differs from cellular wireless networks that need base stations to deliver and receive the packets. Each node plays the role as a router. When one of them wants to deliver packets to destination out of its coverage, intermediate nodes will forward this packet to the next node till the destination node receive it. In traditional cellular wireless networks, generally we need to establish base stations in advance. Fixed nodes far and near connect to the backbone and become a wireless network environment. In this network the customer who wants to communicate with another must locate in the base station coverage. If user moved out of base station's service scope, he can't take the communication. Consequently, we need to establish enough base stations to achieve the objective. Ad hoc networks do not demand fixed network infrastructures and centralized management mechanisms, as well as can be built anytime, anywhere rapidly. Ad hoc networks also have the feature of self-creating, self-organization and elf-management as well as deploy and remove network easily. Ad hoc network has above advantages. However, the Ad hoc network environment has the following restricts [1], including of Network topology instable, Limited energy constrained and Limited network bandwidth-constrained QoS Routing with Link Stability in Mobile A

Assembling a cellulase cocktail and a cellodextrin transporter into a yeast host for CBP ethanol production

Background: Many microorganisms possess enzymes that can efficiently degrade lignocellulosic materials, but donot have the capability to produce a large amount of ethanol. Thus, attempts have been made to transform suchenzymes into fermentative microbes to serve as hosts for ethanol production. However, an efficient host for aconsolidated bioprocess (CBP) remains to be found. For this purpose, a synthetic biology technique that cantransform multiple genes into a genome is instrumental. Moreover, a strategy to select cellulases that interactsynergistically is needed.Results: To engineer a yeast for CBP bio-ethanol production, a synthetic biology technique, called “promoter-basedgene assembly and simultaneous overexpression” (PGASO), that can simultaneously transform and express multiplegenes in a kefir yeast, Kluyveromyces marxianus KY3, was recently developed. To formulate an efficient cellulasecocktail, a filter-paper-activity assay for selecting heterologous cellulolytic enzymes was established in this study andused to select five cellulase genes, including two cellobiohydrolases, two endo-β-1,4-glucanases and onebeta-glucosidase genes from different fungi. In addition, a fungal cellodextrin transporter gene was chosen totransport cellodextrin into the cytoplasm. These six genes plus a selection marker gene were one-step assembledinto the KY3 genome using PGASO. Our experimental data showed that the recombinant strain KR7 could expressthe five heterologous cellulase genes and that KR7 could convert crystalline cellulose into ethanol.Conclusion: Seven heterologous genes, including five cellulases, a cellodextrin transporter and a selection marker,were simultaneously transformed into the KY3 genome to derive a new strain, KR7, which could directly convertcellulose to ethanol. The present study demonstrates the potential of our strategy of combining a cocktailformulation protocol and a synthetic biology technique to develop a designer yeast host

Use of Seasonal Influenza Vaccination and Its Associated Factors among Elderly People with Disabilities in Taiwan: A Population-Based Study

Influenza immunization among elderly people with disabilities is a critical public health concern; however, few studies have examined the factors associated with vaccination rates in non-Western societies.By linking the National Disability Registration System and health service claims dataset from the National Health Insurance program, this population-based study investigated the seasonal influenza vaccination rate among elderly people with disabilities in Taiwan (N = 283,172) in 2008. A multivariate logistic regression analysis was conducted to adjust for covariates.Nationally, only 32.7% of Taiwanese elderly people with disabilities received influenza vaccination. The strongest predictor for getting vaccinated among older Taiwanese people with disabilities was their experience of receiving an influenza vaccination in the previous year (adjusted odds ratio [AOR] = 6.80, 95% confidence interval [CI]: 6.67-6.93). Frequent OPD use (AOR = 1.85, 95% CI: 1.81-1.89) and undergoing health examinations in the previous year (AOR = 1.66, 95% CI: 1.62-1.69) also showed a moderate and significant association with receiving an influenza vaccination.Although free influenza vaccination has been provided in Taiwan since 2001, influenza immunization rates among elderly people with disabilities remain low. Policy initiatives are required to address the identified factors for improving influenza immunization rates among elderly people with disabilities
