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

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

A Statistics-Based And An Simple Physics-Based Models Toward An Operational And Early Flood Warning System

Life and property losses because of disasters such as flood and landslide are getting dramatic increases for past years. Frequent extreme weather events have even worsened the damages globally. Given sufficient information in advance, disaster preparedness and management can be well-settled. The damages and losses can be mitigated and even prevented. An early disaster warning system with enough leadtimes is essential for decision-makers to take prevented measures and execute cautions. This study proposed a prototype of an early disaster warning system which issues warnings for rainfall related disasters such as flood and landslide. Using ensemble quantitative precipitation forecasts, the system could estimate the disaster risk and issue possible threat warnings up to 72 hours in advance. The system is a statistics-based, instead of physics-based model to meet the real time operational needs. The advantage is to provide the information and issue the warnings rapidly which helps the decision-makers have more time to deploy the rescue forces such as manpower and water pumps. For the flood forecasts, the proposed system integrated artificial intelligence with historical records, design capacity of storm sewer system, and threshold rainfall to identify the high risk areas in a township level. A simple physics-based model then was imposed to identify possible flooding areas downscale to the village level. The landslide susceptibility model was developed using the logistic regression that used rainfall, topography and geology as the geo-environment variables affecting slope stability. According to occurrence of disaster and available observed records, the proposed system used typhoon events from 2010 to 2012 in Pingtung County, Taiwan to evaluate the performance. The spatial and temporal comparisons with observations demonstrated promising potential as a valuable reference for better emergency response to alleviate the loss of lives and property
