This feature is termed licensed assisted access (LAA). The channel sensing (clean channel assessment, CCA) is required before any transmission on these unlicensed carriers, in order to make sure the harmonious co-existence of LAA with other radio access technology in the unlicensed band. Obviously, the CCA threshold is very critical, which decides whether the transmission right following CCA is delivered in time and without collisions. An improper CCA threshold may cause buffer overflow of some eNodeBs if the eNodeBs are heavily loaded with the traffic. Thus, to solve these problems, we propose an adaptive threshold adjustment method for CCA in the LAA downlink. Both the load and transmission opportunities are concerned. The trend of the LAA throughput as the threshold varies is obtained, which guides the threshold adjustment. The co-existing between LAA and Wi-Fi is particularly tested. The results from system-level simulation confirm the merits of our design, especially in heavy traffic cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LTE" title="LTE">LTE</a>, <a href="https://publications.waset.org/abstracts/search?q=LAA" title=" LAA"> LAA</a>, <a href="https://publications.waset.org/abstracts/search?q=CCA" title=" CCA"> CCA</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20adjustment" title=" threshold adjustment"> threshold adjustment</a> </p> <a href="https://publications.waset.org/abstracts/130135/adaptive-threshold-adjustment-of-clear-channel-assessment-in-laa-down-link" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130135.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">764</span> Threshold Concepts in TESOL: A Thematic Analysis of Disciplinary Guiding Principles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neil%20Morgan">Neil Morgan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The notion of Threshold Concepts has offered a fertile new perspective on the transformative effects of mastery of particular concepts on student understanding of subject matter and their developing identities as inductees into disciplinary discourse communities. Only by successfully traversing key knowledge thresholds, it is claimed, can neophytes gain access to the more sophisticated understandings of subject matter possessed by mature members of a discipline. This paper uses thematic analysis of disciplinary guiding principles to identify nine candidate Threshold Concepts that appear to underpin effective TESOL practice. The relationship between these candidate TESOL Threshold Concepts, TESOL principles, and TESOL instructional techniques appears to be amenable to a schematic representation based on superordinate categories of TESOL practitioner concern and, as such, offers an alternative to the view of Threshold Concepts as a privileged subset of disciplinary core concepts. The paper concludes by exploring the potential of a Threshold Concepts framework to productively inform TESOL initial teacher education (ITE) and in-service education and training (INSET). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TESOL" title="TESOL">TESOL</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20concepts" title=" threshold concepts"> threshold concepts</a>, <a href="https://publications.waset.org/abstracts/search?q=TESOL%20principles" title=" TESOL principles"> TESOL principles</a>, <a href="https://publications.waset.org/abstracts/search?q=TESOL%20ITE%2FINSET" title=" TESOL ITE/INSET"> TESOL ITE/INSET</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20of%20practice" title=" community of practice"> community of practice</a> </p> <a href="https://publications.waset.org/abstracts/127795/threshold-concepts-in-tesol-a-thematic-analysis-of-disciplinary-guiding-principles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">763</span> Criterion-Referenced Test Reliability through Threshold Loss Agreement: Fuzzy Logic Analysis Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ali%20Alavidoost">Mohammad Ali Alavidoost</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Bozorgian"> Hossein Bozorgian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Criterion-referenced tests (CRTs) are designed to measure student performance against a fixed set of predetermined criteria or learning standards. The reliability of such tests cannot be based on internal reliability. Threshold loss agreement is one way to calculate the reliability of CRTs. However, the selection of master and non-master in such agreement is determined by the threshold point. The problem is if the threshold point witnesses a minute change, the selection of master and non-master may have a drastic change, leading to the change in reliability results. Therefore, in this study, the Fuzzy logic approach is employed as a remedial procedure for data analysis to obviate the threshold point problem. Forty-one Iranian students were selected; the participants were all between 20 and 30 years old. A quantitative approach was used to address the research questions. In doing so, a quasi-experimental design was utilized since the selection of the participants was not randomized. Based on the Fuzzy logic approach, the threshold point would be more stable during the analysis, resulting in rather constant reliability results and more precise assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criterion-referenced%20tests" title="criterion-referenced tests">criterion-referenced tests</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20loss%20agreement" title=" threshold loss agreement"> threshold loss agreement</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20point" title=" threshold point"> threshold point</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic%20approach" title=" fuzzy logic approach"> fuzzy logic approach</a> </p> <a href="https://publications.waset.org/abstracts/135929/criterion-referenced-test-reliability-through-threshold-loss-agreement-fuzzy-logic-analysis-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135929.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">762</span> The Impact of Temperature on the Threshold Capillary Pressure of Fine-Grained Shales </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talal%20Al-Bazali">Talal Al-Bazali</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Mohammad"> S. Mohammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The threshold capillary pressure of shale caprocks is an important parameter in CO₂ storage modeling. A correct estimation of the threshold capillary pressure is not only essential for CO₂ storage modeling but also important to assess the overall economical and environmental impact of the design process. A standard step by step approach has to be used to measure the threshold capillary pressure of shale and non-wetting fluids at different temperatures. The objective of this work is to assess the impact of high temperature on the threshold capillary pressure of four different shales as they interacted with four different oil based muds, air, CO₂, N₂, and methane. This study shows that the threshold capillary pressure of shale and non-wetting fluid is highly impacted by temperature. An empirical correlation for the dependence of threshold capillary pressure on temperature when different shales interacted with oil based muds and gasses has been developed. This correlation shows that the threshold capillary pressure decreases exponentially as the temperature increases. In this correlation, an experimental constant (α) appears, and this constant may depend on the properties of shale and non-wetting fluid. The value for α factor was found to be higher for gasses than for oil based muds. This is consistent with our intuition since the interfacial tension for gasses is higher than those for oil based muds. The author believes that measured threshold capillary pressure at ambient temperature is misleading and could yield higher values than those encountered at in situ conditions. Therefore one must correct for the impact of temperature when measuring threshold capillary pressure of shale at ambient temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capillary%20pressure" title="capillary pressure">capillary pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=shale" title=" shale"> shale</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=thresshold" title=" thresshold"> thresshold</a> </p> <a href="https://publications.waset.org/abstracts/65146/the-impact-of-temperature-on-the-threshold-capillary-pressure-of-fine-grained-shales" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65146.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">371</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">761</span> Combined Localization, Beamforming, and Interference Threshold Estimation in Underlay Cognitive System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Nasr">Omar Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Naguib"> Yasser Naguib</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hafez"> Mohamed Hafez </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims at providing an innovative solution for blind interference threshold estimation in an underlay cognitive network to be used in adaptive beamforming by secondary user Transmitter and Receiver.

EEPROMs (Electrically Erasable Read Only Memories) are a good candidate for this purpose because they are inexpensive and are sensitive to radiation exposure. When the total ionizing dose threshold is reached, an EEPROM chip will show signs of damage that can be monitored and transmitted by less susceptible electronics. The dose rate can then be determined from the known threshold dose and the exposure time, assuming the radiation field remains constant with time. Therefore, the threshold dose needs to be well understood before this method can be used. There are many factors affecting the threshold dose, such as the gamma ray energy spectrum, the operating voltage, etc. The purpose of this study was to experimentally determine how the threshold dose depends on dose rate, temperature, voltage, and duty factor. It was found that the duty factor has the strongest effect on the total ionizing dose threshold, while the effect of the other three factors that were investigated is less significant. The effect of temperature was found to be opposite to that expected to result from annealing and is yet to be understood. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EEPROM" title="EEPROM">EEPROM</a>, <a href="https://publications.waset.org/abstracts/search?q=ionizing%20radiation" title=" ionizing radiation"> ionizing radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20effects%20on%20electronics" title=" radiation effects on electronics"> radiation effects on electronics</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20ionizing%20dose" title=" total ionizing dose"> total ionizing dose</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title=" wireless sensor networks"> wireless sensor networks</a> </p> <a href="https://publications.waset.org/abstracts/77107/investigation-of-factors-affecting-the-total-ionizing-dose-threshold-of-electrically-erasable-read-only-memories-for-use-in-dose-rate-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77107.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">757</span> Investigation of Threshold Voltage Shift in Gamma Irradiated N-Channel and P-Channel MOS Transistors of CD4007</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Boorboor">S.

MOSFETs, most common transistors in today’s digital and analog circuits, are severely sensitive to TID damage. In this work, the threshold voltage shift of CD4007 device, which is an integrated circuit including P-channel and N-channel MOS transistors, was investigated for low dose gamma irradiation under different gate bias voltages. We used linear extrapolation method to extract threshold voltage from I<sub>D</sub>-V<sub>G</sub> characteristic curve. The results showed that the threshold voltage shift was approximately 27.5 mV/Gy for N-channel and 3.5 mV/Gy for P-channel transistors at the gate bias of |9 V| after irradiation by Co-60 gamma ray source. Although the sensitivity of the devices under test were strongly dependent to biasing condition and transistor type, the threshold voltage shifted linearly versus accumulated dose in all cases. The overall results show that the application of CD4007 as an electronic buffer in a radiation therapy system is limited by TID damage. However, this integrated circuit can be used as a cheap and sensitive radiation dosimeter for accumulated dose measurement in radiation therapy systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=threshold%20voltage%20shift" title="threshold voltage shift">threshold voltage shift</a>, <a href="https://publications.waset.org/abstracts/search?q=MOS%20transistor" title=" MOS transistor"> MOS transistor</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20extrapolation" title=" linear extrapolation"> linear extrapolation</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20irradiation" title=" gamma irradiation"> gamma irradiation</a> </p> <a href="https://publications.waset.org/abstracts/55355/investigation-of-threshold-voltage-shift-in-gamma-irradiated-n-channel-and-p-channel-mos-transistors-of-cd4007" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">756</span> Threshold Competency of Students in Graduate School</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Terada%20Pinyo">Terada Pinyo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is the survey research, designed to find out the threshold competency of graduate students in terms of knowledge excellency and professional skills proficiency based on Thai Qualifications Framework for Higher Education (TQF).

Most of the defects in the SMT process are mainly related to the quality of solder paste printing. These defects lead to considerable manufacturing costs in the electronics assembly industry. Therefore, the solder paste inspection (SPI) machine for controlling and monitoring the amount of solder paste printing has become an important part of the production process. So far, the setting of the SPI threshold is based on statistical analysis and experts’ experiences to determine the appropriate threshold settings. Because the production data are not normal distribution and there are various variations in the production processes, defects related to solder paste printing still occur. In order to solve this problem, this paper proposes an online machine learning algorithm, called the automatic threshold adjustment (ATA) algorithm, and closed-loop architecture in the SMT process to determine the best threshold settings. Simulation experiments prove that our proposed threshold settings improve the accuracy from 99.85% to 100%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data%20analytics" title="big data analytics">big data analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=Industry%204.0" title=" Industry 4.0"> Industry 4.0</a>, <a href="https://publications.waset.org/abstracts/search?q=SPI%20threshold%20setting" title=" SPI threshold setting"> SPI threshold setting</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20mount%20technology" title=" surface mount technology"> surface mount technology</a> </p> <a href="https://publications.waset.org/abstracts/114158/automatic-adjustment-of-thresholds-via-closed-loop-feedback-mechanism-for-solder-paste-inspection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114158.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">753</span> Sustainability Effect of Informality and Globalisation: Capturing Spatial Spillovers and Threshold Effects in African and European Economies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Segun%20Thompson%20Bolarinwa">Segun Thompson Bolarinwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Munacinga%20Simatele"> Munacinga Simatele</a>, <a href="https://publications.waset.org/abstracts/search?q=Adedamola%20Victoria%20Adegbuyi"> Adedamola Victoria Adegbuyi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using World Bank’s nascent measure of sustainability, this paper examines the relationship between informality and sustainability in selected 7 African and 7 European developing economies.

To date, most of the white-box techniques are used to protect block cipher implementations. However, a large proportion of the white-box implementations are proven to be vulnerable to affine equivalence attacks and other algebraic attacks, as well as differential computation analysis (DCA). In this paper, we identify a class of block ciphers for which we propose a method of constructing white-box implementations. Our method is based on threshold implementations and operations in composite fields. The resulting implementations consist of lookup tables and few exclusive OR operations. All intermediate values (inputs and outputs of the lookup tables) are masked. The threshold implementation makes the distribution of the masked values uniform and independent of the original inputs, and the operations in composite fields reduce the size of the lookup tables. The white-box implementations can provide resistance against algebraic attacks and DCA-like attacks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=white-box" title="white-box">white-box</a>, <a href="https://publications.waset.org/abstracts/search?q=block%20cipher" title=" block cipher"> block cipher</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20field" title=" composite field"> composite field</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20implementation" title=" threshold implementation"> threshold implementation</a> </p> <a href="https://publications.waset.org/abstracts/108457/constructing-white-box-implementations-based-on-threshold-shares-and-composite-fields" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108457.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">751</span> A Proposal for an Excessivist Social Welfare Ordering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20De%20Sandi">V. De Sandi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we characterize a class of rank-weighted social welfare orderings that we call ”Excessivist.” The Excessivist Social Welfare Ordering (eSWO) judges incomes above a fixed threshold θ as detrimental to society. To accomplish this, the identification of a richness or affluence line is necessary. We employ a fixed, exogenous line of excess. We define an eSWF in the form of a weighted sum of individual’s income. This requires introducing n+1 vectors of weights, one for all possible numbers of individuals below the threshold. To do this, the paper introduces a slight modification of the class of rank weighted class of social welfare function. Indeed, in our excessivist social welfare ordering, we allow the weights to be both positive (for individuals below the line) and negative (for individuals above). Then, we introduce ethical concerns through an axiomatic approach. The following axioms are required: continuity above and below the threshold (Ca, Cb), anonymity (A), absolute aversion to excessive richness (AER), pigou dalton positive weights preserving transfer (PDwpT), sign rank preserving full comparability (SwpFC) and strong pareto below the threshold (SPb). Ca, Cb requires that small changes in two income distributions above and below θ do not lead to changes in their ordering. AER suggests that if two distributions are identical in any respect but for one individual above the threshold, who is richer in the first, then the second should be preferred by society. This means that we do not care about the waste of resources above the threshold; the priority is the reduction of excessive income. According to PDwpT, a transfer from a better-off individual to a worse-off individual despite their relative position to the threshold, without reversing their ranks, leads to an improved distribution if the number of individuals below the threshold is the same after the transfer or the number of individuals below the threshold has increased. SPb holds only for individuals below the threshold. The weakening of strong pareto and our ethics need to be justified; we support them through the notion of comparative egalitarianism and income as a source of power. SwpFC is necessary to ensure that, following a positive affine transformation, an individual does not become excessively rich in only one distribution, thereby reversing the ordering of the distributions. Given the axioms above, we can characterize the class of the eSWO, getting the following result through a proof by contradiction and exhaustion: Theorem 1. A social welfare ordering satisfies the axioms of continuity above and below the threshold, anonymity, sign rank preserving full comparability, aversion to excessive richness, Pigou Dalton positive weight preserving transfer, and strong pareto below the threshold, if and only if it is an Excessivist-social welfare ordering. A discussion about the implementation of different threshold lines reviewing the primary contributions in this field follows. What the commonly implemented social welfare functions have been overlooking is the concern for extreme richness at the top. The characterization of Excessivist Social Welfare Ordering, given the axioms above, aims to fill this gap. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comparative%20egalitarianism" title="comparative egalitarianism">comparative egalitarianism</a>, <a href="https://publications.waset.org/abstracts/search?q=excess%20income" title=" excess income"> excess income</a>, <a href="https://publications.waset.org/abstracts/search?q=inequality%20aversion" title=" inequality aversion"> inequality aversion</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20welfare%20ordering" title=" social welfare ordering"> social welfare ordering</a> </p> <a href="https://publications.waset.org/abstracts/177679/a-proposal-for-an-excessivist-social-welfare-ordering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">750</span> Improving Capability of Detecting Impulsive Noise </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farbod%20Rohani">Farbod Rohani</a>, <a href="https://publications.waset.org/abstracts/search?q=Elyar%20Ghafoori"> Elyar Ghafoori</a>, <a href="https://publications.waset.org/abstracts/search?q=Matin%20Saeedkondori"> Matin Saeedkondori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Impulse noise is electromagnetic emission which generated by many house hold appliances that are attached to the electrical network.

One selector-one resistor configuration has shown the most promising way to resolve the crosstalk issue without affecting the scalability and high-density integration of the RRAM array. By comparison with other candidates of selectors (such as diodes and nonlinear devices), threshold switching selectors dominated by formation/spontaneous rupture of fragile conductive filaments have been proved to possess low voltages, high selectivity, and ultra-low current leakage. However, the flexibility and transparency of selectors are barely mentioned. Therefore, it is a matter of urgency to develop a selector with highly flexible and transparent properties to assist the application of RRAM for a diversity of memory devices. In this work, threshold switching selectors were designed using a facilely solution-processed fabrication on AgNWs@PDMS composite films, which show high flexibility, transparency and scratch resistance. As-fabricated threshold switching selectors also have revealed relatively high selectivity (~107), low operating voltages (Vth < 1 V) and good switching performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20and%20transparent" title="flexible and transparent">flexible and transparent</a>, <a href="https://publications.waset.org/abstracts/search?q=resistive%20random-access%20memory" title=" resistive random-access memory"> resistive random-access memory</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanowires" title=" silver nanowires"> silver nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20switching%20selector" title=" threshold switching selector"> threshold switching selector</a> </p> <a href="https://publications.waset.org/abstracts/119260/solution-processed-threshold-switching-selectors-based-on-highly-flexible-transparent-and-scratchable-silver-nanowires-conductive-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119260.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">746</span> A Novel Model for Saturation Velocity Region of Graphene Nanoribbon Transistor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Khaledian">Mohsen Khaledian</a>, <a href="https://publications.waset.org/abstracts/search?q=Razali%20Ismail"> Razali Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Saeidmanesh"> Mehdi Saeidmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdiar%20Hosseinghadiry"> Mahdiar Hosseinghadiry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A semi-analytical model for impact ionization coefficient of graphene nanoribbon (GNR) is presented.

And there is a limit in investigating quantitatively and systematically the mechanism of correlation between economic development and GHG emissions considering inherent differences among manufacturing sub-sectors. Considering the sectorial characteristics, the manufacturing sub-sectors with various impacts of output on GHG emissions may be explained by different development modes in each manufacturing sub-sector, such as investment scale, technology level and the level of international competition. In order to assess the environmental impact associated with any specific level of economic development and explore the factors that affect GHG emissions in China’s manufacturing industry during the process of economic growth, using the threshold Stochastic Impacts by Regression on Population, Affluence and Technology (STIRPAT) model, this paper investigated the influence impacts of GHG emissions for China’s manufacturing sectors of different stages of economic development. A data set from 28 manufacturing sectors covering an 18-year period was used. Results demonstrate that output per capita and investment scale contribute to increasing GHG emissions while energy efficiency, R&D intensity and FDI mitigate GHG emissions. Results also verify the nonlinear effect of output per capita on emissions as: (1) the Environmental Kuznets Curve (EKC) hypothesis is supported when threshold point RMB 31.19 million is surpassed; (2) the driving strength of output per capita on GHG emissions becomes stronger as increasing investment scale; (3) the threshold exists for energy efficiency with the positive coefficient first and negative coefficient later; (4) the coefficient of output per capita on GHG emissions decreases as R&D intensity increases. (5) FDI shows a reduction in elasticity when the threshold is compassed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=China" title="China">China</a>, <a href="https://publications.waset.org/abstracts/search?q=GHG%20emissions" title=" GHG emissions"> GHG emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20industry" title=" manufacturing industry"> manufacturing industry</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20STIRPAT%20model" title=" threshold STIRPAT model"> threshold STIRPAT model</a> </p> <a href="https://publications.waset.org/abstracts/61271/characteristics-and-drivers-of-greenhouse-gas-ghg-emissions-from-chinas-manufacturing-industry-a-threshold-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61271.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">428</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">744</span> Queueing Modeling of M/G/1 Fault Tolerant System with Threshold Recovery and Imperfect Coverage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madhu%20Jain">Madhu Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20Kumar%20Meena"> Rakesh Kumar Meena</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates a finite M/G/1 fault tolerant multi-component machining system.

Materials and Methods: A total of ten cone-beam computed tomography (CBCT) images were collected. The airway volume and MCA of each patient were analyzed using the automatic airway segmentation function in the CBCT DICOM viewer (Romexis). Airway volume and MCA measurements were conducted on each CBCT sagittal view with fifteen different threshold values from the Romexis software, Ranging from 300 to 1000. Duplicate DICOM files, in axial view, were imported into Image J for concurrent airway volume and MCA analysis as the gold standard. The airway volume and MCA measured from Romexis and Image J were compared using a t-test with Bonferroni correction, and statistical significance was set at p<0.003. Results: Concerning airway volume, thresholds of 600 to 850 as well as 1000, exhibited results that were not significantly distinct from those obtained through Image J. Regarding MCA, employing thresholds from 400 to 850 within Romexis Viewer showed no variance from Image J. Notably, within the threshold range of 600 to 850, there were no statistically significant differences observed in both airway volume and MCA analyses, in comparison to Image J. Conclusion: This study demonstrated that the utilization of Planmeca Romexis Viewer 6.4.3.3 within threshold range of 600 to 850 yields airway volume and MCA measurements that exhibit no statistically significant variance in comparison to measurements obtained through Image J. This outcome holds implications for diagnosing upper airway obstructions and post-orthodontic surgical monitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airway%20analysis" title="airway analysis">airway analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=airway%20segmentation" title=" airway segmentation"> airway segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=cone%20beam%20computed%20tomography" title=" cone beam computed tomography"> cone beam computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold" title=" threshold"> threshold</a> </p> <a href="https://publications.waset.org/abstracts/186082/effect-of-threshold-configuration-on-accuracy-in-upper-airway-analysis-using-cone-beam-computed-tomography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186082.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">44</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">742</span> An Investigation of Rainfall Changes in KanganCity During Years 1964 to 2003</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Borzou%20Faramarzi">Borzou Faramarzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farideh%20Azimi"> Farideh Azimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Gohardoust"> Azam Gohardoust</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Ghasemi%20Ghasemvand"> Abbas Ghasemi Ghasemvand</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Mirzaei"> Maryam Mirzaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mandana%20Amani"> Mandana Amani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, attempts were made to examine and analyze the trend for rainfall changes in Kangan City, Booshehr Province, during the time span 1964 to 2003, using seven rainfall threshold indices based on 50 climate extremes indices approved by WMO–CCL/CLIVAR. These indices include days with heavy precipitations, days with rainfalls, frequency of rainfall threshold values, intensity of rainfall threshold values, percentage of rainfall threshold values, successive days of rainfall, and successive days with no precipitation. Results are indicative of the fact that Kangan City climatic conditions have become more dried than before. Indices days with heavy precipitations and days with rainfalls do not show a certain trend in Kangan City. Frequency, intensity, and percentage of rainfall threshold values in the station under investigation do not indicate a certain trend. In analysis of time series of rainfall extreme indices, generally, it was revealed that Kangan City is influenced by general factors of global warming. Calculation of values for the next 10 years based on ARIMA models demonstrates a continuation of warming trends in Kangan City. On the whole, rainfall conditions in Kangan City have experienced more dry periods compared to the past, the trend which is also observable for next 10 years. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climatic%20indices" title="climatic indices">climatic indices</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=extreme%20temperature%20and%20precipitation" title=" extreme temperature and precipitation"> extreme temperature and precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series" title=" time series"> time series</a> </p> <a href="https://publications.waset.org/abstracts/52075/an-investigation-of-rainfall-changes-in-kangancity-during-years-1964-to-2003" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52075.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">272</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">741</span> Threshold Sand Detection Limits for Acoustic Monitors in Multiphase Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Ponnagandla">Vinod Ponnagandla</a>, <a href="https://publications.waset.org/abstracts/search?q=Brenton%20McLaury"> Brenton McLaury</a>, <a href="https://publications.waset.org/abstracts/search?q=Siamack%20Shirazi"> Siamack Shirazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sand production can lead to deposition of particles or erosion. Low production rates resulting in deposition can partially clog systems and cause under deposit corrosion. Commercially available nonintrusive acoustic sand detectors are attractive as they claim to detect sand production. Acoustic sand detectors are used during oil and gas production; however, operators often do not know the threshold detection limits of these devices. It is imperative to know the detection limits to appropriately plan for cleaning of separation equipment or examine risk of erosion. These monitors are based on detecting the acoustic signature of sand as the particles impact the pipe walls. The objective of this work is to determine threshold detection limits for acoustic sand monitors that are commercially available. The minimum threshold sand concentration that can be detected in a pipe are determined as a function of flowing gas and liquid velocities. A large scale flow loop with a 4-inch test section is utilized. Commercially available sand monitors (ClampOn and Roxar) are evaluated for different flow regimes, sand sizes and pipe orientation (vertical and horizontal). The manufacturers’ recommend that the monitors be placed on a bend to maximize the number of particle impacts, so results are shown for monitors placed at 45 and 90 degree positions in a bend. Acoustic sand monitors that clamp to the outside of pipe are passive and listen for solid particle impact noise. The threshold sand rate is calculated by eliminating the background noise created by the flow of gas and liquid in the pipe for various flow regimes that are generated in horizontal and vertical test sections. The average sand sizes examined are 150 and 300 microns. For stratified and bubbly flows the threshold sand rates are much higher than other flow regimes such as slug and annular flow regimes that are investigated. However, the background noise generated by slug flow regime is very high and cause a high uncertainty in detection limits. The threshold sand rates for annular flow and dry gas conditions are the lowest because of high gas velocities. The effects of monitor placement around elbows that are in vertical and horizontal pipes are also examined for 150 micron. The results show that the threshold sand rates that are detected in vertical orientation are generally lower for all various flow regimes that are investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20monitor" title="acoustic monitor">acoustic monitor</a>, <a href="https://publications.waset.org/abstracts/search?q=sand" title=" sand"> sand</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20flow" title=" multiphase flow"> multiphase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold" title=" threshold"> threshold</a> </p> <a href="https://publications.waset.org/abstracts/63189/threshold-sand-detection-limits-for-acoustic-monitors-in-multiphase-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">407</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">740</span> Application of Smplify-X Algorithm with Enhanced Gender Classifier in 3D Human Pose Estimation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiahe%20Liu">Jiahe Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongyang%20Yu"> Hongyang Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Miao%20Luo"> Miao Luo</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Qian"> Feng Qian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The widespread application of 3D human body reconstruction spans various fields.

Currently, the Pleistocene aquifer has been continuously exploited on average of 154,163m3/day, distributed mainly in the districts of Nghia Hung, Hai Hau, a part of Truc Ninh, Y Yen, Nam Truc and Giao Thuy. The groundwater level is still on a declining trend, saltwater intrusion in this freshwater lens can occur if the growth rate in exploitation is maintained. This study focused on groundwater sustainable use by means of 4 groups of criteria including: Groundwater quality and pollution; Aquifers’ productivity and capacity; Environment impacts due to exploitation (groundwater level decline, land subsidence due to water exploitation); Social and economic impacts. Using a combination of methods including field surveys, geophysics, hydrogeochemistry, isotope and numerical models to determine safe groundwater exploitation thresholds for the whole study area has been determined to be 544,314m3/day and the actual exploitation amount is currently about 30% compared to the safe exploitation threshold. However, it should also be noted that the current groundwater exploitation threshold and level of its exploitation compared to the safe exploitation threshold of each locality are not the same. From this result, the groundwater exploitation threshold map of the study area was established to serve the management, licensing and orientation of groundwater exploitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criteria" title="criteria">criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20groundwater%20lens" title=" fresh groundwater lens"> fresh groundwater lens</a>, <a href="https://publications.waset.org/abstracts/search?q=pleistocene" title=" pleistocene"> pleistocene</a>, <a href="https://publications.waset.org/abstracts/search?q=Nam%20Dinh" title=" Nam Dinh"> Nam Dinh</a> </p> <a href="https://publications.waset.org/abstracts/145972/sustainable-use-of-fresh-groundwater-lens-of-pleistocene-aquifer-in-nam-dinh-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145972.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">738</span> Effectiveness of Dry Needling on Pain and Pressure Point Threshold in Cervicogenic Headache</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20Chandra%20Patra">Ramesh Chandra Patra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajay%20P.%20Gautam"> Ajay P.

Headache that originated from upper cervical spine and refereed to the one side of the head and/or face is known as cervicogenic headache (CH) which constitute15% to 20% among all the headaches. In our best knowledge manual therapy is often advocated for managing CH, but very little focus given on muscle system although it is a musculoskeletal disorder. In this study, 75 patients with CH were selected and divided into two groups Group A: Manual therapy and Group B: dry needling along with manual therapy group. Assessment was done using NPRS (0-10) for pain, wide spread pressure pain threshold using an algometer at the beginning and end of the study. There is a consistent reduction in pain and tenderness in both the group but significant improvement was shown in combined group. Outcome of the study has explored that the effectiveness of dry needling along with Mulligan is more beneficial in patients with cervicogenic headaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervicogenic%20headaches" title="cervicogenic headaches">cervicogenic headaches</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20needling" title=" dry needling"> dry needling</a>, <a href="https://publications.waset.org/abstracts/search?q=NPRS" title=" NPRS"> NPRS</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20point%20threshold" title=" pressure point threshold"> pressure point threshold</a> </p> <a href="https://publications.waset.org/abstracts/77128/effectiveness-of-dry-needling-on-pain-and-pressure-point-threshold-in-cervicogenic-headache" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77128.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">229</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">737</span> An ANN-Based Predictive Model for Diagnosis and Forecasting of Hypertension</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Obe%20Olumide%20Olayinka">Obe Olumide Olayinka</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Balanica"> Victor Balanica</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugen%20Neagoe"> Eugen Neagoe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of hypertension are often lethal thus its early detection and prevention is very important for everybody. In this paper, a neural network (NN) model was developed and trained based on a dataset of hypertension causative parameters in order to forecast the likelihood of occurrence of hypertension in patients. Our research goal was to analyze the potential of the presented NN to predict, for a period of time, the risk of hypertension or the risk of developing this disease for patients that are or not currently hypertensive. The results of the analysis for a given patient can support doctors in taking pro-active measures for averting the occurrence of hypertension such as recommendations regarding the patient behavior in order to lower his hypertension risk. Moreover, the paper envisages a set of three example scenarios in order to determine the age when the patient becomes hypertensive, i.e. determine the threshold for hypertensive age, to analyze what happens if the threshold hypertensive age is set to a certain age and the weight of the patient if being varied, and, to set the ideal weight for the patient and analyze what happens with the threshold of hypertensive age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title="neural network">neural network</a>,
