Our methodology employs cryptographic techniques, including Merkle Trees, Bulletproof, and zkSnark, to verify that total assets equal or exceed total liabilities, represented by customer funds. Importantly, this verification is achieved without disclosing sensitive information such as the total asset value, customer count, or cold wallet addresses. We delve into the construction and implementation of this methodology. While the system is robust and scalable, we also identify areas for potential enhancements to improve its efficiency and versatility. As the digital asset landscape continues to evolve, our approach provides a solid foundation for ensuring continued trust and security in digital asset platforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptocurrency" title="cryptocurrency">cryptocurrency</a>, <a href="https://publications.waset.org/abstracts/search?q=crypto-currency" title=" crypto-currency"> crypto-currency</a>, <a href="https://publications.waset.org/abstracts/search?q=proof-of-reserve" title=" proof-of-reserve"> proof-of-reserve</a>, <a href="https://publications.waset.org/abstracts/search?q=por" title=" por"> por</a>, <a href="https://publications.waset.org/abstracts/search?q=zero-knowledge" title=" zero-knowledge"> zero-knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=ZKP" title=" ZKP"> ZKP</a> </p> <a href="https://publications.waset.org/abstracts/173727/zero-knowledge-proof-of-reserve-a-confidential-approach-to-cryptocurrency-asset-verification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173727.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">72</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">85</span> Hong Kong Artists Public Communication of Mental Health Disorders and Coping Techniques - Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Portugal%20Marques%20de%20Carvalho%20Lourenco">Patricia Portugal Marques de Carvalho Lourenco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Money, status, beauty, popularity, widespread public adulation, glitz and glamour portray a perfumed stress-free existence yet not every rock that glitters is a gold nugget and mental disorders are not an exclusivity of middle/low societal classes.

Several drivers usually compose the demographic challenge, coming from the structure and trends of population in the country. As the case of research, three main variables of demographic risk in Lithuania have been singled out and have been used in making up the analysis. Over the last two decades, the country has presented a peculiar demographic situation characterized by pessimistic fertility trends, negative net migration rate and rising life expectancy that make the significant changes in labor-age population. This study, therefore, sets out to assess the relative impact of these risk factors both individually and in aggregate, while assuming economic trends to evolve historically. The evidence is presented using data of pension funds that operate in Lithuania and are financed by defined-contribution plans. To achieve this goal, the discrete-time pension fund’s value model is developed that reflects main operational modalities: contribution income from current participants and new entrants, pension disbursement and administrative expenses; it also fluctuates based on returns from investment activity. Age-structured Leslie population dynamics model has been integrated into the main model to describe the dynamics of fertility, migration and mortality rates upon age. Validation has concluded that Leslie model adequately fits the current population trends in Lithuania. The elasticity of pension system is examined using Loimaranta efficiency as a measure for comparison of plausible long-term developments of demographic risks. With respect to the research question, it was found that demographic risks have different levels of influence on future value of aggregated pension funds: The fertility rates have the highest importance, while mortality rates give only a minor impact. Further studies regarding the role of trying out different economic scenarios in the integrated model would be worthwhile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asset%20liability%20modelling" title="asset liability modelling">asset liability modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=Leslie%20model" title=" Leslie model"> Leslie model</a>, <a href="https://publications.waset.org/abstracts/search?q=pension%20funds" title=" pension funds"> pension funds</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20dynamics" title=" population dynamics"> population dynamics</a> </p> <a href="https://publications.waset.org/abstracts/60105/asset-liability-modelling-for-pension-funds-by-introducing-leslie-model-for-population-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60105.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">269</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">83</span> Spatial Comparative Analysis on Travels of Mackay in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shao-Chi%20Chien">Shao-Chi Chien</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying-Ju%20Chen"> Ying-Ju Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiao-Yu%20Tseng"> Chiao-Yu Tseng</a>, <a href="https://publications.waset.org/abstracts/search?q=Wan-Ting%20Lee"> Wan-Ting Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Wen%20Cheng"> Yi-Wen Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dr. George Leslie Mackay arrived at Takoukang (now Port of Kaohsiung) in Taiwan on December 30, 1871. When Dr. Mackay dedicated at Taiwan for 30 years, he has been an important factor in such areas as preaching, medical and engaged in education. Many researchers have thoroughly studied Dr. Mackay's travels to understand his impact on the state of education, medicine and religion in Taiwan. In the 30-year period of hard work, Dr. Mackay's made outstanding influence on the church in Taiwan. Therefore, the present study will be the mission of the establishment of hospitals, schools, churches which preaching, education, and medicine whether there are related the number of comparisons to explore. According to The Diaries of George Leslie Mackay, our research uses the Geographic Information System (GIS) to map the location of Dr. Mackay's travel in Taiwan and compares it with today's local churches, hospitals, and schools whether there are related the number of comparisons to explore. Therefore, our research focuses on the whole of Taiwan, divided into missionary, medical and education as the main content of the three major parts. Additionally, use of point layer, the surface layer of the property table to establish, in-depth mission of Dr. Mackay's development in Taiwan and Today's comparison.

In the Al-Pc cluster, certain functional bond lengths and bond angles have been observed. The Quantum chemical method (DFT and TD-DFT) and Vibrational spectra properties of AlPc are studied. X-ray pattern reveals the crystalline structure along with the (242) orientation of the AlPc organic thin layer. UV-Vis shows the frequency selective behavior of the device. The absorbance of such layer exhibits a high value within the UV range and two consecutive peaks within visible range. Spin coating is used to make an organic diode based on the Aluminium-phthalocynanine (AlPc-Cl) molecule. Under dark and light conditions, electrical characterization of Ag/AlPc/Si/Au is obtained. The diode's high rectifying capability (about 1x104) is subsequently discovered. While the height barrier is constant and saturation current is greatly reliant on light, the ideality factor of such a diode increases to 6.9 which confirms the non-ideality of such a device. The Cheung-Cheung technique is employed to further the investigation and gain additional data such as series resistance and barrier height. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AlPc-Cl%20organic%20material" title="AlPc-Cl organic material">AlPc-Cl organic material</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20optic" title=" nonlinear optic"> nonlinear optic</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20filter" title=" optical filter"> optical filter</a>, <a href="https://publications.waset.org/abstracts/search?q=diode" title=" diode"> diode</a> </p> <a href="https://publications.waset.org/abstracts/148773/the-nonlinear-optical-properties-analysis-of-alpc-cl-organic-compound" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148773.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">138</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">81</span> A Cosmic Time Dilation Model for the Week of Creation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwok%20W.%20Cheung">Kwok W.

We hypothesize that the reference timeframe of God’s creation is associated with some cosmic time different from the earth's time. We show that the scale factor of earth time to cosmic time can be determined by the solution of the Friedmann equations. Based on this scale factor and some basic assumptions, we derive a Cosmic Time Dilation model that harmonizes the literal meaning of creation days and scientific discoveries with remarkable accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cosmological%20expansion" title="cosmological expansion">cosmological expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20dilation" title=" time dilation"> time dilation</a>, <a href="https://publications.waset.org/abstracts/search?q=creation" title=" creation"> creation</a>, <a href="https://publications.waset.org/abstracts/search?q=genesis" title=" genesis"> genesis</a>, <a href="https://publications.waset.org/abstracts/search?q=relativity" title=" relativity"> relativity</a>, <a href="https://publications.waset.org/abstracts/search?q=Big%20Bang" title=" Big Bang"> Big Bang</a>, <a href="https://publications.waset.org/abstracts/search?q=biblical%20hermeneutics" title=" biblical hermeneutics"> biblical hermeneutics</a> </p> <a href="https://publications.waset.org/abstracts/181901/a-cosmic-time-dilation-model-for-the-week-of-creation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181901.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">91</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">80</span> An Application-Based Indoor Environmental Quality (IEQ) Calculator for Residential Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwok%20W.%20Mui">Kwok W.

In this talk, we showcase a new field demonstrating the possibility for harnessing sound energy sources at considerably higher frequencies (10 MHz to 1 GHz) compared to conventional ultrasound (kHz and up to ~2 MHz) for crystalising and manipulating a variety of nanoscale materials. At these frequencies, cavitation—which underpins most sonochemical processes—is largely absent, suggesting that altogether fundamentally different mechanisms are at dominant. Examples include the crystallization of highly oriented structures, quasi-2D metal-organic frameworks and nanocomposites. These fascinating examples reveal how the highly nonlinear electromechanical coupling associated with high-frequency surface vibration gives rise to molecular ordering and assembly on the nano and microscale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-frequency%20acoustics" title="high-frequency acoustics">high-frequency acoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidics" title=" microfluidics"> microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallisation" title=" crystallisation"> crystallisation</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20nanomaterials" title=" composite nanomaterials"> composite nanomaterials</a> </p> <a href="https://publications.waset.org/abstracts/147372/high-frequency-sonochemistry-a-new-field-of-cavitationfree-acoustic-materials-synthesis-and-manipulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147372.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">121</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">77</span> A Study of Parameters That Have an Influence on Fabric Prints in Judging the Attractiveness of a Female Body Shape</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Man%20N.%20M.%20Cheung">Man N.

Fibres prevent brittle behaviour and improve several mechanical properties of SCC. In this paper, an experimental investigation of the effect of three-dimensional (3D) fibres on the mechanical properties of SCC has been conducted. Seven SCC mixtures, namely SCC with no fibres as a reference mix, and six 3D steel fibre reinforced SCC mixes were prepared. Two different sizes of 3D steel fibres with perimeters of 115 mm and 220 mm at different fibre contents of 1%, 2%, and 3% (by cement weight) were considered. The mechanical characteristics were obtained through compressive, splitting tensile, and flexural strength tests. The test results revealed that the addition of 3D fibres improves the mechanical properties of SCC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20concrete" title="self-compacting concrete">self-compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20steel%20fibres" title=" three-dimensional steel fibres"> three-dimensional steel fibres</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=splitting%20tensile%20strength" title=" splitting tensile strength"> splitting tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a> </p> <a href="https://publications.waset.org/abstracts/130889/mechanical-properties-of-self-compacting-concrete-with-three-dimensional-steel-fibres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130889.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">153</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">73</span> Biofilm Is Facilitator for Microplastic Ingestion in Green Mussel Perna Viridis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yixuan%20Wang">Yixuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20C.%20Y.%20Wong"> A.

The biofilm that forms on MPs alters their characteristics and perplexes users, including filter-feeders, some of whom choose to eat MPs that have biofilm. It has been proposed that filter feeders like mussels and other bivalves could serve as bioindicators of MP pollution. Mussels are considered selective feeders with particle sorting capability. Two sizes (27-32 µm and 90-106 µm), shapes (microspheres and microfibers), and types (polyethylene, polystyrene and polyester) of MPs were available for the green mussel, Perna viridis, at three concentrations (100 P/ml, 1000 P/ml and 10,000 P/ml). These MPs were incubated in the sea for 0, 3 or 14 days for biofilm development. The presence of the biofilm significantly affected the ingestion of MPs, and the mussels preferred MPs with biofilm, with a higher preference observed for biofilm with a longer incubation period. Additionally, the ingestion rate varied with the interaction between the concentration, size and form of MPs. The findings are discussed in relation to the possibility that mussels serve as MP bioindicators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marine%20miroplastics" title="marine miroplastics">marine miroplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm" title=" biofilm"> biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=bioindicator" title=" bioindicator"> bioindicator</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20mussel%20perna%20viridis" title=" green mussel perna viridis"> green mussel perna viridis</a> </p> <a href="https://publications.waset.org/abstracts/183324/biofilm-is-facilitator-for-microplastic-ingestion-in-green-mussel-perna-viridis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183324.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">60</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">72</span> Foreign Language Teaching Anxiety Among In-Service English Teachers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guofang%20Zeng">Guofang Zeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Anisa%20Cheung"> Anisa Cheung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Teacher emotions are vitally important for the classroom environment and students’ language attainment; however, studies concerning foreign language teaching anxiety (FLTA) remain scarce. This study examined FLTA by administering questionnaires to 235 in-service teachers to investigate the impacts of educational stages and teaching experience on FLTA. The statistical results show that secondary school teachers exhibit significantly higher levels of FLTA than their primary counterparts, especially in “lack of student interest” and “fear of negative evaluation”. Novice teachers are significantly more anxious than experienced teachers in the dimension of ‘teaching inexperience’, while no other differences are shown in other aspects. No interaction effects are found between the two variables. Pedagogical implications for understanding FLTA in different educational and experiential stages and corresponding anxiety-reducing strategies are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foreign%20language%20teaching%20anxiety" title="foreign language teaching anxiety">foreign language teaching anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=in-service%20teachers" title=" in-service teachers"> in-service teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=novice%20and%20experienced%20teachers" title=" novice and experienced teachers"> novice and experienced teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20and%20secondary%20school" title=" primary and secondary school"> primary and secondary school</a> </p> <a href="https://publications.waset.org/abstracts/194111/foreign-language-teaching-anxiety-among-in-service-english-teachers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194111.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">8</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">71</span> Tracing Back the Bot Master </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sneha%20Leslie">Sneha Leslie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current situation in the cyber world is that crimes performed by Botnets are increasing and the masterminds (botmaster) are not detectable easily. The botmaster in the botnet compromises the legitimate host machines in the network and make them bots or zombies to initiate the cyber-attacks. This paper will focus on the live detection of the botmaster in the network by using the strong framework 'metasploit', when distributed denial of service (DDOS) attack is performed by the botnet. The affected victim machine will be continuously monitoring its incoming packets. Once the victim machine gets to know about the excessive count of packets from any IP, that particular IP is noted and details of the noted systems are gathered. Using the vulnerabilities present in the zombie machines (already compromised by botmaster), the victim machine will compromise them. By gaining access to the compromised systems, applications are run remotely. By analyzing the incoming packets of the zombies, the victim comes to know the address of the botmaster. This is an effective and a simple system where no specific features of communication protocol are considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bonet" title="bonet">bonet</a>, <a href="https://publications.waset.org/abstracts/search?q=DDoS%20attack" title=" DDoS attack"> DDoS attack</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20security" title=" network security"> network security</a>, <a href="https://publications.waset.org/abstracts/search?q=detection%20system" title=" detection system"> detection system</a>, <a href="https://publications.waset.org/abstracts/search?q=metasploit%20framework" title=" metasploit framework"> metasploit framework</a> </p> <a href="https://publications.waset.org/abstracts/19912/tracing-back-the-bot-master" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19912.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">254</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">70</span> 3D Shape Knitting: Loop Alignment on a Surface with Positive Gaussian Curvature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20T.%20Cheung">C.

Two loop alignment methods are introduced to handle a surface with positive Gaussian curvature. As weft knitting is a two-dimensional (2D) knitting mechanism that the knitting cam carrying the feeders moves in two directions only, left and right, the knitted fabric generated grows in width and length but not in depth. Therefore, a 3D shape is required to be flattened to a 2D plane with surface area preserved for knitting. On this flattened plane, dimensional measurements are taken for loop alignment. The way these measurements being taken derived two different loop alignment methods. In this paper, only plain knitted structure was considered. Each knitted loop was taken as a basic unit for loop alignment in order to achieve the required geometric dimensions, without the inclusion of other stitches which give textural dimensions to the fabric. Two loop alignment methods were experimented and compared. Only one of these two can successfully preserve the dimensions of the shape. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20knitting" title="3D knitting">3D knitting</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20shape" title=" 3D shape"> 3D shape</a>, <a href="https://publications.waset.org/abstracts/search?q=loop%20alignment" title=" loop alignment"> loop alignment</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20Gaussian%20curvature" title=" positive Gaussian curvature"> positive Gaussian curvature</a> </p> <a href="https://publications.waset.org/abstracts/46772/3d-shape-knitting-loop-alignment-on-a-surface-with-positive-gaussian-curvature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46772.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">345</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">69</span> Phase Detection Using Infrared Spectroscopy: A Build up to Inline Gas–Liquid Flow Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwame%20Sarkodie">Kwame Sarkodie</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Cheung"> William Cheung</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20R.%20Fergursson"> Andrew R.

In order to fully characterize fluid phases in a stream or containment, there needs to be a profound knowledge of the existing composition of fluids present. This introduces a problem for real-time monitoring of fluid dynamics such as fluid distributions, and phase fractions. This work presents a simple technique of correlating absorbance spectrums of water, oil and air bubble present in containment. These spectra absorption outputs are derived by using an Fourier Infrared spectrometer. During the testing, air bubbles were introduced into static water column and oil containment and with light absorbed in the infrared regions of specific wavelength ranges. Attenuation coefficients are derived for various combinations of water, gas and oil which reveal the presence of each phase in the samples. The results from this work are preliminary and viewed as a build up to the design of a multiphase flow rig which has an infrared sensor pair to be used for multiphase flow characterization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attenuation" title="attenuation">attenuation</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared" title=" infrared"> infrared</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase" title=" multiphase"> multiphase</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroscopy" title=" spectroscopy"> spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/71887/phase-detection-using-infrared-spectroscopy-a-build-up-to-inline-gas-liquid-flow-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71887.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">368</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">68</span> The Sectoral Differences in the Use of Construction Incentive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qiuwen%20Ma">Qiuwen Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Sai%20On%20Cheung"> Sai On Cheung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Incentive contracting has been developed to push the agent team for extra effort. Generally, there are three types of incentive arrangement, namely incentive/penalty for super performance/underperformance, risk/reward sharing and future business opportunities. It is found that there are significant differences in the use of incentive arrangement in private and public projects. In Hong Kong, very few public projects have used future business as incentivizer whereas private developers often signal repeated business coupled with heavy penalty. This study was conducted to identify various attributes affecting the use of I/D in both private and public engineering sectors of Hong Kong. The diverging preferences were unveiled with reference to a literature review and semi-structured interviews with industry experts. The findings reveal the public/private sectors would consider the implementation issues regarding the various performance targets. The most deterministic factor for the public sector is about accountability. The private sector is in general skeptical about the need to provide extra for the contractors for what they have already contracted to perform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20incentive" title="construction incentive">construction incentive</a>, <a href="https://publications.waset.org/abstracts/search?q=public%2Fprivate%20projects" title=" public/private projects"> public/private projects</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-structured%20interview" title=" semi-structured interview"> semi-structured interview</a>, <a href="https://publications.waset.org/abstracts/search?q=hong%20kong" title=" hong kong"> hong kong</a> </p> <a href="https://publications.waset.org/abstracts/171647/the-sectoral-differences-in-the-use-of-construction-incentive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171647.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">102</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">67</span> The Applicability of International Humanitarian Law to Non-State Actors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yin%20Cheung%20Lam">Yin Cheung Lam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 1949, the ratification of the Geneva Conventions heralded the international community’s adoption of a new universal and non-discriminatory approach to human rights in situations of conflict. However, with the proliferation of international terrorism after the 9/11 attacks on the United States (U.S.), the international community’s uneven and contradictory implementations of international humanitarian law (IHL) questioned its agenda of universal human rights. Specifically, the derogation from IHL has never been so pronounced in the U.S. led ‘War on Terror’. While an extensive literature has ‘assessed the impact’ of the implementation of the Geneva Conventions, limited attention has been paid to interrogating the ways in which the Geneva Conventions and its resulting implementation have functioned to discursively reproduce certain understandings of human rights between states and non-state actors. Through a discursive analysis of the Geneva Conventions and the conceptualization of human rights in relation to terrorism, this thesis problematises the way in which the U.S. has understood and reproduced understandings of human rights. Using the U.S. ‘War on Terror’ as an example, it seeks to extend previous analyses of the U.S.’ practice of IHL through a qualitative discursive analysis of the human rights content that appears in the Geneva Conventions in addition to the speeches and policy documents on the ‘War on Terror’. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discursive%20analysis" title="discursive analysis">discursive analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=non-state%20actors" title=" non-state actors"> non-state actors</a>, <a href="https://publications.waset.org/abstracts/search?q=war%20on%20terror" title=" war on terror"> war on terror</a> </p> <a href="https://publications.waset.org/abstracts/27898/the-applicability-of-international-humanitarian-law-to-non-state-actors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27898.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">606</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">66</span> Utilizing Quicklime (Calcium Oxide) for Self-Healing Properties in Innovation of Coconut Husk Fiber Bricks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christian%20Gabriel%20Mariveles">Christian Gabriel Mariveles</a>, <a href="https://publications.waset.org/abstracts/search?q=Darelle%20Jay%20Gallardo"> Darelle Jay Gallardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Leslie%20Dayaoen"> Leslie Dayaoen</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurenz%20Paul%20Diaz"> Laurenz Paul Diaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> True experimental research with descriptive analysis was conducted. Utilizing Quicklime (Calcium Oxide) for self-healing properties of coconut husk fibre concrete brick. There are 2 setups established: the first one has the 1:1:2 ratio of calcium oxide, cement and sand, and the second one has a 2:1:2 ratio of the same variables. The bricks are made from the residences along Barangay Greater Lagro. The mixture of sand and cement is mixed with coconut husk fibers and then molded with different ratios in the molder. After the drying of cement, the researchers tested the bricks in the laboratory for compressive strength. The brick with the highest PSI is picked by the researchers to drop into freefall testing, and it makes remarkable remarks as it is deformed after dropping to different heights with a maximum of 20 feet. Unfortunately, the self-healing capabilities were not observed during the 12 weeks of monitoring. However, the brick was weighed after 12 weeks of monitoring, and it increased in weight by 0.030 kg. from 1.833 kg. to 1.863 kg. meaning that this ratio 2 has the potential to self-heal, but 12 weeks of monitoring by the researchers is not enough to conclude that it has a significant difference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self%20healing" title="self healing">self healing</a>, <a href="https://publications.waset.org/abstracts/search?q=coconut%20husk%20bricks" title=" coconut husk bricks"> coconut husk bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=research" title=" research"> research</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium%20oxide" title=" calcium oxide"> calcium oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=utilizing%20quicklime" title=" utilizing quicklime"> utilizing quicklime</a> </p> <a href="https://publications.waset.org/abstracts/184457/utilizing-quicklime-calcium-oxide-for-self-healing-properties-in-innovation-of-coconut-husk-fiber-bricks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184457.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">42</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">65</span> Incentivize Contracting Partners of Public Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sai%20On%20Cheung">Sai On Cheung</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiuwen%20Ma"> Qiuwen Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Fong%20Chung%20Lee"> Fong Chung Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to increased project complexity and technological advancement in the last decade, the designers and contractors are expected to put more efforts to achieve project goals. To render extra efforts from the agents, incentivization has become one of the primary strategies for the client. Despite increased academia interest in the design of incentive strategies, there is still a need for discussion about the underlying motivations and favourable conditions to make incentives effective. Therefore, this study focuses on the effects of motivations and favourable conditions for the use of incentives in public projects. Questionnaire survey is used as the data collection tool. The questionnaire survey was piloted through interviews with professionals from Hong Kong public sector. A total of 100 responses were collected for this survey. Accountability and organizational effectiveness were found to be the prime objectives of incentives installed by public clients. Furthermore, a list of favourable conditions for incentivization and its consequent effects on cost, schedule, risk and public opinions were identified. To conclude, this study analyses the means and ends of the use of incentives in public projects in Hong Kong. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=incentives" title="incentives">incentives</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20accountability" title=" public accountability"> public accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20effectiveness" title=" project effectiveness"> project effectiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20opinions" title=" public opinions"> public opinions</a> </p> <a href="https://publications.waset.org/abstracts/176416/incentivize-contracting-partners-of-public-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176416.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">67</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">64</span> Statistical Classification, Downscaling and Uncertainty Assessment for Global Climate Model Outputs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Queen%20Suraajini%20Rajendran">Queen Suraajini Rajendran</a>, <a href="https://publications.waset.org/abstracts/search?q=Sai%20Hung%20Cheung"> Sai Hung Cheung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Statistical down scaling models are required to connect the global climate model outputs and the local weather variables for climate change impact prediction.

The purpose of this study is to explore the use of rankings in strategic planning by low-ranked universities in this highly competitive higher education market. A sample of non-elite universities was selected for a content analysis based on the measures used by The Guardian rankings. Interestingly, these universities care about their rankings within a single national system. The content analysis appears to be an effective approach to investigating the presence of such influences. It is particularly noteworthy that all sampled universities use these measure terminologies in their strategic plans, missions and news coverage on their institutional web-pages. This analysis may be an example of the key challenges that many low-ranking universities in England are probably facing in the highly competitive and diversified higher education market. These universities use rankings to communicate with their stakeholders, mainly students, in order to fill places to secure their major source of funding. The study concludes with comments on the likely effects of the rankings paradigm in undermining the contributions of non-elite universities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=League%20tables" title="League tables">League tables</a>, <a href="https://publications.waset.org/abstracts/search?q=measures" title=" measures"> measures</a>, <a href="https://publications.waset.org/abstracts/search?q=post-1992%20universities" title=" post-1992 universities"> post-1992 universities</a>, <a href="https://publications.waset.org/abstracts/search?q=ranking" title=" ranking"> ranking</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a> </p> <a href="https://publications.waset.org/abstracts/133199/the-impact-of-university-league-tables-on-the-development-of-non-elite-universities-a-case-study-of-england" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133199.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">61</span> A Survey of Recognizing of Daily Living Activities in Multi-User Smart Home Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kulsoom%20S.%20Bughio">Kulsoom S.

This clay mineral can be prepared into functional nanoparticles that can be used as fillers in other nanomaterials such as nanofibers to achieve special properties. In this study, two types of iron-modified MMT, Iron-MMT (FeMMT) and Zero Valent Iron-MMT (ZVIMMT) were synthesized via ion exchange technique. The modified clay was incorporated in polymer nanofibers which were produced using a process called electrospinning. ICP analysis confirmed that clay modification was successful where there is an observed decrease in the concentration of Na and an increase in the concentration of Fe after ion exchange. XRD analysis also confirmed that modification took place because of the changes in the d-spacing of Na-MMT from 11.5 Å to 13.6 Å and 12.6 Å after synthesis of FeMMT and ZVIMMT, respectively. SEM images of the electrospun nanofibers revealed that the ZVIMMT-filled fibers have a smaller average diameter than the FeMMT-filled fibers because of the lower resistance of the suspensions of the former to the elongation force from the applied electric field. The resistance to the electric field was measured by getting the bulk voltage of the suspensions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title="electrospinning">electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=montmorillonite" title=" montmorillonite"> montmorillonite</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20science" title=" materials science"> materials science</a> </p> <a href="https://publications.waset.org/abstracts/8295/synthesis-of-iron-modified-montmorillonite-as-filler-for-electrospun-nanocomposite-fibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8295.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">345</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">59</span> Experts' Perception of Secondary Education Quality Management Challenges in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aklilu%20Alemu">Aklilu Alemu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tak%20Cheung%20Chan"> Tak Cheung Chan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Following the intensification of secondary education in the developing world, the attention of Ethiopia has currently shifted to its quality education and its management. This study is aimed to explore experts’ perceptions of quality management challenges in secondary education in Ethiopia. The researchers employed a case study design recruiting participating supervisors from the Ministry of Education, region, zone, wereda, and cluster by using a purposeful sampling technique. Twenty-six interviewees took part in this study. The researchers employed NVivo 8 versions together with a thematic analysis process to analyze the data. This study revealed that major problems that affected quality management practices in Ethiopia were: lack of qualified experts at all levels; lack of accountability in every echelon; the changing nature of teacher education; the ineffectiveness of teacher-licensing programs; and lack of educational budget and the problem of utilizing this limited budget. The study concluded that the experts at different levels were not genuinely fulfilling their roles and responsibilities. Therefore, the Ministry of Finance and Economic Development, together with the concerned parties, needs to reconsider budget allocation for secondary education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education%20quality" title="education quality">education quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20challenge" title=" quality challenge"> quality challenge</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20management" title=" quality management"> quality management</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20education" title=" secondary education"> secondary education</a> </p> <a href="https://publications.waset.org/abstracts/144531/experts-perception-of-secondary-education-quality-management-challenges-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144531.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">216</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">58</span> A Comparison of the Adsorption Mechanism of Arsenic on Iron-Modified Nanoclays</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Leo%20L.%20Dela%20Cruz">Michael Leo L.

A comparative study on the adsorption mechanism of arsenic on iron modified nanoclays was undertaken. Iron intercalated montmorillonite (Fe-MMT) and montmorillonite supported zero-valent iron (ZVI-MMT) were the adsorbents investigated in this study. Fe-MMT was produced through ion-exchange by replacing the sodium intercalated ions in montmorillonite with iron (III) ions. The iron (III) in Fe-MMT was later reduced to zero valent iron producing ZVI-MMT. Adsorption study was performed by batch technique. Obtained data were fitted to intra-particle diffusion, pseudo-first order, and pseudo-second-order models and the Elovich equation to determine the kinetics of adsorption. The adsorption of arsenic on Fe-MMT followed the intra-particle diffusion model with intra-particle rate constant of 0.27 mg/g-min0.5. Arsenic was found to be chemically bound on ZVI-MMT as suggested by the pseudo-second order and Elovich equation. The derived pseudo-second order rate constant was 0.0027 g/mg-min with initial adsorption rate computed from the Elovich equation was 113 mg/g-min. <p class="card-text"><strong>Keywords:</strong> <a
