Therefore, nowadays environmental planning objective tends to the issues of respecting nature and coexisting with nature. As a result, the natural environment analysis, e.g., the analysis of topography, soil, hydrology, climate, vegetation, is highly emphasized. On the other hand, Feng Shui has been a criterion of site selection for residence in Eastern since the ancient times and has had farther influence on site selection for castles and even for temples and tombs. The primary criterion of site selection is judging the quality of Long: mountain range, Sha: nearby mountains, Shui: hydrology, Xue: foundation, Xiang: aspect, which are similar to the environmental variables of mountain range, topography, hydrology and aspect. For the reason, a lot researchers attempt to probe into the connection between the criterion of Feng Shui and environmental planning factors. Most researches only discussed with the composition and theory of space of Feng Shui, but there is no research which explained Feng Shui through the environmental field. Consequently, this study reviewed the theory of Feng Shui through the environmental planning viewpoint and assembled essential composition factors of Feng Shui. The results of this study point. From literature review and comparison of theoretical meanings, we find that the ideal principles for planning the Feng Shui environment can also be used for environmental planning. Therefore, this article uses 12 ideal environmental features used in Feng Shui to contrast the natural aspects of the environment and make comparisons with previous research and classifies the environmental factors into climate, topography, hydrology, vegetation, and soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20composition%20of%20Feng%20Shui" title="the composition of Feng Shui">the composition of Feng Shui</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20planning" title=" environmental planning"> environmental planning</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20selection" title=" site selection"> site selection</a>, <a href="https://publications.waset.org/abstracts/search?q=main%20components%20of%20the%20Feng%20Shui%20environment" title=" main components of the Feng Shui environment"> main components of the Feng Shui environment</a> </p> <a href="https://publications.waset.org/abstracts/20624/the-discussion-on-the-composition-of-feng-shui-by-the-environmental-planning-viewpoint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20624.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">509</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">287</span> Tourist’s Perception and Identification of Landscape Elements of Traditional Village</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mengxin%20Feng">Mengxin Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Xu"> Feng Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiyong%20Lai"> Zhiyong Lai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a typical representative of the countryside, traditional Chinese villages are rich in cultural landscape resources and historical information, but they are still in continuous decline. The problems of people's weak protection awareness and low cultural recognition are still serious, and the protection of cultural heritage is imminent. At the same time, with the rapid development of rural tourism, its cultural value has been explored and paid attention to again. From the perspective of tourists, this study aimed to explore people's perception and identity of cultural landscape resources under the current cultural tourism development background. We selected eleven typical landscape elements of Lingshui Village, a traditional village in Beijing, as research objects and conducted a questionnaire survey with two scales of perception and identity to explore the characteristics of people's perception and identification of landscape elements. We found that there was a strong positive correlation between the perception and identity of each element and that geographical location influenced visitors' overall perception. The perception dimensions scored the highest in location, and the lowest in history and culture, and the identity dimensions scored the highest in meaning and lowest in emotion. We analyzed the impact of visitors' backgrounds on people's perception and identity characteristics and found that age and education were two important factors. The elderly had a higher degree of perceived identity, as the familiarity effect increased their attention. Highly educated tourists had more stringent criteria for perception and identification. The above findings suggest strategies for conserving and optimizing landscape elements in the traditional village to improve the acceptance and recognition of cultural information in traditional villages, which will inject new vitality into the development of traditional villages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traditional%20village" title="traditional village">traditional village</a>, <a href="https://publications.waset.org/abstracts/search?q=tourist%20perception" title=" tourist perception"> tourist perception</a>, <a href="https://publications.waset.org/abstracts/search?q=landscape%20elements" title=" landscape elements"> landscape elements</a>, <a href="https://publications.waset.org/abstracts/search?q=perception%20and%20identity" title=" perception and identity"> perception and identity</a> </p> <a href="https://publications.waset.org/abstracts/165244/tourists-perception-and-identification-of-landscape-elements-of-traditional-village" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165244.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">146</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">286</span> DLtrace: Toward Understanding and Testing Deep Learning Information Flow in Deep Learning-Based Android Apps</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jie%20Zhang">Jie Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qianyu%20Guo"> Qianyu Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Tieyi%20Zhang"> Tieyi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiyong%20Feng"> Zhiyong Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaohong%20Li"> Xiaohong Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the widespread popularity of mobile devices and the development of artificial intelligence (AI), deep learning (DL) has been extensively applied in Android apps. Compared with traditional Android apps (traditional apps), deep learning based Android apps (DL-based apps) need to use more third-party application programming interfaces (APIs) to complete complex DL inference tasks. However, existing methods (e.g., FlowDroid) for detecting sensitive information leakage in Android apps cannot be directly used to detect DL-based apps as they are difficult to detect third-party APIs. To solve this problem, we design DLtrace; a new static information flow analysis tool that can effectively recognize third-party APIs. With our proposed trace and detection algorithms, DLtrace can also efficiently detect privacy leaks caused by sensitive APIs in DL-based apps. Moreover, using DLtrace, we summarize the non-sequential characteristics of DL inference tasks in DL-based apps and the specific functionalities provided by DL models for such apps. We propose two formal definitions to deal with the common polymorphism and anonymous inner-class problems in the Android static analyzer. We conducted an empirical assessment with DLtrace on 208 popular DL-based apps in the wild and found that 26.0% of the apps suffered from sensitive information leakage. Furthermore, DLtrace has a more robust performance than FlowDroid in detecting and identifying third-party APIs. The experimental results demonstrate that DLtrace expands FlowDroid in understanding DL-based apps and detecting security issues therein. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20computing" title="mobile computing">mobile computing</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning%20apps" title=" deep learning apps"> deep learning apps</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitive%20information" title=" sensitive information"> sensitive information</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20analysis" title=" static analysis"> static analysis</a> </p> <a href="https://publications.waset.org/abstracts/152909/dltrace-toward-understanding-and-testing-deep-learning-information-flow-in-deep-learning-based-android-apps" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152909.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">179</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">285</span> Boryl Radical-Promoted Dehydroxylative Alkylation of 3-Hydroxyoxindole Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Tebeka%20Simur">Tesfaye Tebeka Simur</a>, <a href="https://publications.waset.org/abstracts/search?q=Tian-Yu%20Peng"> Tian-Yu Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Feng%20Wang"> Yi-Feng Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiu-Wei%20Wu"> Xiu-Wei Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng-Lian%20Zhang"> Feng-Lian Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A boryl radical-promoted dehydroxylative alkylation of 3-hydroxy-oxindole derivatives is achieved.

Mostly used methods for this purpose are direct pulp capping and pulpotomy, which consist of placement of biocompatible materials and bio-inductors on the exposed pulp tissue to preserve its health and stimulate repair by mineralized tissue formation. In this study, we developed a material (calcium phosphate cement (CPC)/gypsum composite) as the dental pulp capping material for shortening setting time and improving handling properties.

Ni. This cost-effective catalyst system efficiently utilizes pyrolysis carbon-based materials and waste hydrogen. Additionally, it yields environmentally friendly products without requiring extra heat sources in practical SCR devices. Density functional theory elucidates the mechanism of NO heterogeneous reduction by H₂ on Ni-decorated char surfaces. Two distinct reaction paths were identified, one involving the intermediate product N₂O and the other not. These pathways exhibit different rate-determination steps and activation energies. Kinetic analysis indicates that the N₂O byproduct pathway has a lower activation energy. Experimental results corroborate the theoretical findings. Thus, this research enhances our mechanistic understanding of the NO-H₂ reaction over char and offers insights for optimizing catalyst design in low-temperature NO reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=char-based%20catalysis" title="char-based catalysis">char-based catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=NO%20reduction" title=" NO reduction"> NO reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=DFT%20study" title=" DFT study"> DFT study</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneous%20reaction" title=" heterogeneous reaction"> heterogeneous reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=low-temperature%20H%E2%82%82-reduction" title=" low-temperature H₂-reduction"> low-temperature H₂-reduction</a> </p> <a href="https://publications.waset.org/abstracts/171909/theoretical-and-experimental-study-on-the-no-reduction-by-h2-over-char-decorated-with-ni-at-low-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171909.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">79</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">282</span> Design and Implementation of a Cross-Network Security Management System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiyong%20Shan">Zhiyong Shan</a>, <a href="https://publications.waset.org/abstracts/search?q=Preethi%20Santhanam"> Preethi Santhanam</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Namboodiri"> Vinod Namboodiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajiv%20Bagai"> Rajiv Bagai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the emerging network worms and attacks have distributive characteristics, which can spread globally in a very short time.

First, we describe the system in macrostructure and microstructure; then discuss three key problems when building HD-NSMS: device model, alert mechanism, and emergency response mechanism; lastly, we describe the implementation of HD-NSMS.

Because of constantly switching postures of motion axis, five-axis CNC machine’s composite stiffness changes during CNC machining.

Geotextile has been widely used to reinforce the soil for the purpose of reducing the settlement of the soil. A series of physical model tests were performed to investigate the settlement of footing under cyclic loading. The settlement of the footing, ground deformation and the vertical earth pressure in subsoil were presented and discussed under different types of geotextiles. The results indicate that including geotextiles significantly decreases the footing settlement and the stiffer the geotextile, the less the settlement. Under cyclic loading, the soil below the footing shows dilation within certain depths and beyond that it experiences contraction. The location of footing relative to the retaining wall has important effects on the deformation behavior of the soil in the ground, and the closer the footing to the retaining wall, the greater the contraction soil shows. This is because the retaining wall experienced greater lateral displacement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physical%20model%20tests" title="physical model tests">physical model tests</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20retaining%20wall" title=" reinforced retaining wall"> reinforced retaining wall</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=footing" title=" footing"> footing</a> </p> <a href="https://publications.waset.org/abstracts/150601/study-of-the-behavior-of-geogrid-mechanically-stabilized-earth-walls-under-cyclic-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150601.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">155</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">279</span> Social Semiotics in the Selected Films of Chito S.

Garcia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Films are famous expressions of art in the country. As an expression of art, it serves as a medium in which a culture is reflected. This paper studied how films reflected the Filipino culture. In this study, social semiotics was used to analyze the semiotic resources identified in the film. The films studied were 'Feng Shui', 'Sukob', and 'The Healing', which were three of the highest grossing horror films of Chito S. Roño. The objectives of the paper were (1) to identify the semiotic resources in the film, (2) to extract their meanings, and (3) to determine how these resources were perceived in the Filipino culture. The semiotic resources identified in each film are organized into three categories: color, practices and supernatural occurrences. Each semiotic resource is analyzed through the four dimensions of social semiotics, genre, style, modality, and discourse. For color, some of the semiotic resources identified are red, white and blue; for practices, Hagiolatry, and Mariolatry, faith healing and the belief in superstitions; and for supernatural occurrences, haunting ghosts, doppelganger attacks and returning from the dead were identified. The practices that are prominent in the films are Hagiolatry and Mariolatry, belief in feng shui and belief in faith healers and albularyos. The belief of these practices shows that Filipinos have a dual faith; belief in religion and a belief in superstitions. In short, Filipinos highly practice folk Catholicism and because of this, a mixture of different cultures can be seen, as having molded the Filipino culture to what it is today. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=culture" title="culture">culture</a>, <a href="https://publications.waset.org/abstracts/search?q=film" title=" film"> film</a>, <a href="https://publications.waset.org/abstracts/search?q=semiotics" title=" semiotics"> semiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20semiotics" title=" social semiotics"> social semiotics</a> </p> <a href="https://publications.waset.org/abstracts/76923/social-semiotics-in-the-selected-films-of-chito-s-rono" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76923.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">338</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">278</span> An Experimental Investigation of Microscopic and Macroscopic Displacement Behaviors of Branched-Preformed Particle Gel in High Temperature Reservoirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Weiyao%20Zhu">Weiyao Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bingbing%20Li"> Bingbing Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yajing%20Liu"> Yajing Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiyong%20Song"> Zhiyong Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Branched-preformed particle gel (B-PPG) is a newly developed profile control and oil displacement agent for enhanced oil recovery in major oilfields. To provide a better understanding of the performance of B-PPG in high temperature reservoirs, a comprehensive experimental investigation was conducted by utilizing glass micromodel and synthetic core. The microscopic experimental results show that the B-PPG can selectively flow and plug in large pores. In terms of enhanced oil recovery, the decrease of residual oil in the margin regions (24.6%) was higher than that in the main stream (13.7%), which indicates it enlarged the sweep area. In addition, the effects of B-PPG injection concentration and injection rate on enhanced oil recovery were implemented by core flooding. The macroscopic experimental results indicate that the enhanced oil recovery increased with the increasing of injection concentration. However, the injection rate had a peak value. It is significant to get insight into the behaviors of B-PPG in reservoirs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=branched-preformed%20particle%20gel" title="branched-preformed particle gel">branched-preformed particle gel</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20oil%20recovery" title=" enhanced oil recovery"> enhanced oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=micromodel" title=" micromodel"> micromodel</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20flooding" title=" core flooding"> core flooding</a> </p> <a href="https://publications.waset.org/abstracts/78230/an-experimental-investigation-of-microscopic-and-macroscopic-displacement-behaviors-of-branched-preformed-particle-gel-in-high-temperature-reservoirs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78230.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">198</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">277</span> Traditionalism and Modernity in Seoul’s Urban Planning for the Disabled </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helena%20Park">Helena Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the last three decades, Seoul has experienced an exponential increase in population and concomitant rapid urbanization. With such development, Korea adopted a predominantly Western style of architecture but still based the structures on Korea’s traditionalism and Confucian precepts of pung su (feng shui). While Korean urban planning is focusing on balancing out the modernism and traditionalism in its city architecture, particularly in and landmark sites like The Seoul N Tower and Gyeongbok Palace, the accessibility and convenience concerns of minorities in social groups like the disabled are habitually disregarded. With the implementations of ramps and elevators, the welfare of all citizens seemed to improve. According to the dictates of traditional Korean culture, it was crucial for those construed as “disabled” or “underprivileged” to feel natural in the city of Seoul, which is planned and built with the background aesthetic theory of being harmonized with nature. It was interesting and also alarming to see the extent to which Korean landmarks were lacking facilities for the disabled throughout the city. Standards set by the Ministry of Health and Welfare and the Seoul Metropolitan City insist that buildings accommodate the needs of the disabled as well as the non-disabled equally, but it was hard to find buildings in Seoul - old or new - that fulfilled all the requirements. If fulfilled, some of the facilities were hard to find or not well maintained. There is thus a serious concern for planning reform in connection with Seoul’s 2030 Urban Plan. This paper argues that alternative planning could better integrate Korea’s traditionalist architecture and concepts of pung su rather than insist on the necessity of Western-style modernism as the sole modality for achieving accessibility for the disabled in Korea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessibility" title="accessibility">accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture%20of%20Seoul" title=" architecture of Seoul "> architecture of Seoul </a>, <a href="https://publications.waset.org/abstracts/search?q=Pung%20Su%20%28Feng%20Shui%29" title=" Pung Su (Feng Shui)"> Pung Su (Feng Shui)</a>, <a href="https://publications.waset.org/abstracts/search?q=traditionalism" title=" traditionalism"> traditionalism</a>, <a href="https://publications.waset.org/abstracts/search?q=modernism%20in%20Seoul" title=" modernism in Seoul"> modernism in Seoul</a> </p> <a href="https://publications.waset.org/abstracts/59232/traditionalism-and-modernity-in-seouls-urban-planning-for-the-disabled" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59232.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">234</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">276</span> Automated Testing to Detect Instance Data Loss in Android Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anusha%20Konduru">Anusha Konduru</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiyong%20Shan"> Zhiyong Shan</a>, <a href="https://publications.waset.org/abstracts/search?q=Preethi%20Santhanam"> Preethi Santhanam</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Namboodiri"> Vinod Namboodiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajiv%20Bagai"> Rajiv Bagai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mobile applications are increasing in a significant amount, each to address the requirements of many users. However, the quick developments and enhancements are resulting in many underlying defects. Android apps create and handle a large variety of 'instance' data that has to persist across runs, such as the current navigation route, workout results, antivirus settings, or game state. Due to the nature of Android, an app can be paused, sent into the background, or killed at any time. If the instance data is not saved and restored between runs, in addition to data loss, partially-saved or corrupted data can crash the app upon resume or restart. However, it is difficult for the programmer to manually test this issue for all the activities. This results in the issue of data loss that the data entered by the user are not saved when there is any interruption. This issue can degrade user experience because the user needs to reenter the information each time there is an interruption. Automated testing to detect such data loss is important to improve the user experience. This research proposes a tool, DroidDL, a data loss detector for Android, which detects the instance data loss from a given android application. We have tested 395 applications and found 12 applications with the issue of data loss. This approach is proved highly accurate and reliable to find the apps with this defect, which can be used by android developers to avoid such errors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Android" title="Android">Android</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20testing" title=" automated testing"> automated testing</a>, <a href="https://publications.waset.org/abstracts/search?q=activity" title=" activity"> activity</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20loss" title=" data loss"> data loss</a> </p> <a href="https://publications.waset.org/abstracts/136524/automated-testing-to-detect-instance-data-loss-in-android-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136524.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">237</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">275</span> Precise CNC Machine for Multi-Tasking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haroon%20Jan%20Khan">Haroon Jan Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xian-Feng%20Xu"> Xian-Feng Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Nasir%20Shah"> Syed Nasir Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Anooshay%20Niazi"> Anooshay Niazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CNC machines are not only used on a large scale but also now become a prominent necessity among households and smaller businesses.

The regulations and law of water resources protection and recycling are gradually completed now but still lack of specific water recycling effectiveness checking method. The research focused on the industrial parks that already had been certificated with EIA to establish a professional checking system, carry through and forge ahead to contribute one’s bit in water resources sustainable usage. Taiwan Government Policies of Environmental Impact Assessment established in 1994, some development projects were requested to set certain water recycling ratio for water resources effective usage. The water covers and contains everything because all-inclusive companies enter and be stationed. For control the execution status of industrial park water and waste water recycling ratio about EIA commitment effectively, we invited experts and scholars in this filed to discuss with related organs to formulate the policy and audit plan. Besides, call a meeting to set public version water equilibrium diagrams and recycles parameter. We selected nine industrial parks that were requested set certain water recycling ratio in EIA examination stage and then according to the water usage quantity, we audited 340 factories in these industrial parks with spot and documents examination and got fruitful results – the average water usage of unit area per year of all these examined industrial parks is 31,000 tons/hectare/year, the value is just half of Taiwan industries average. It is obvious that the industrial parks with EIA commitment can decrease the water resources consumption effectively. Taiwan government policies of Environmental Impact Assessment took follow though tracking function into consideration at the beginning. The results of this research verify the importance of the implementing with water recycling to save water resources in EIA commitment. Inducing development units to follow EIA commitment to get the balance between environmental protection and economic development is one of the important EIA value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taiwan%20government%20policies%20of%20environmental%20impact%20assessment" title="Taiwan government policies of environmental impact assessment">Taiwan government policies of environmental impact assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20recycling%20ratio%20of%20EIA%20commitment" title=" water recycling ratio of EIA commitment"> water recycling ratio of EIA commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources%20sustainable%20usage" title=" water resources sustainable usage"> water resources sustainable usage</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20recycling" title=" water recycling"> water recycling</a> </p> <a href="https://publications.waset.org/abstracts/79495/the-review-and-contribution-of-taiwan-government-policies-on-environmental-impact-assessment-to-water-recycling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79495.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">226</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">271</span> Comparison of Frequency-Domain Contention Schemes in Wireless LANs </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Feng">Li Feng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In IEEE 802.11 networks, it is well known that the traditional time-domain contention often leads to low channel utilization.

In this paper, we survey the latest research progress on the weighed frequency-domain contention. We present the basic ideas, work principles of these related schemes and point out their differences. This paper is very useful for further study on frequency-domain contention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=802.11" title="802.11">802.11</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20LANs" title=" wireless LANs"> wireless LANs</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency-domain%20contention" title=" frequency-domain contention"> frequency-domain contention</a>, <a href="https://publications.waset.org/abstracts/search?q=T2F" title=" T2F"> T2F</a> </p> <a href="https://publications.waset.org/abstracts/42959/comparison-of-frequency-domain-contention-schemes-in-wireless-lans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42959.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">459</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">270</span> Design of Effective Decoupling Point in Build-To-Order Systems: Focusing on Trade-Off Relation between Order-To-Delivery Lead Time and Work in Progress</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiyong%20Li">Zhiyong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Katayama"> Hiroshi Katayama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since 1990s, e-commerce and internet business have been grown gradually over the word and customers tend to express their demand attributes in terms of specification requirement on parts, component, product structure etc. This paper deals with designing effective decoupling points for build to order systems under e-commerce environment, which can be realized through tradeoff relation analysis between two major criteria, customer order lead time and value of work in progress. These KPIs are critical for successful BTO business, namely time-based service effectiveness on coping with customer requirements for the first issue and cost effective ness with risk aversive operations for the second issue. Approach of this paper consists of investigation of successful business standing for BTO scheme, manufacturing model development of this scheme, quantitative evaluation of proposed models by calculation of two KPI values under various decoupling point distributions and discussion of the results brought by pattern of decoupling point distribution, where some cases provide the pareto optimum performances. To extract the relevant trade-off relation between considered KPIs among 2-dimensional resultant performance, useful logic developed by former research work, i.e. Katayama and Fonseca, is applied. Obtained characteristics are evaluated as effective information for managing BTO manufacturing businesses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=build-to-order%20%28BTO%29" title="build-to-order (BTO)">build-to-order (BTO)</a>, <a href="https://publications.waset.org/abstracts/search?q=decoupling%20point" title=" decoupling point"> decoupling point</a>, <a href="https://publications.waset.org/abstracts/search?q=e-commerce" title=" e-commerce"> e-commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=order-to-delivery%20lead%20time%20%28ODLT%29" title=" order-to-delivery lead time (ODLT)"> order-to-delivery lead time (ODLT)</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20in%20progress%20%28WIP%29" title=" work in progress (WIP)"> work in progress (WIP)</a> </p> <a href="https://publications.waset.org/abstracts/30691/design-of-effective-decoupling-point-in-build-to-order-systems-focusing-on-trade-off-relation-between-order-to-delivery-lead-time-and-work-in-progress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30691.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">325</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">269</span> 3D Receiver Operator Characteristic Histogram</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaoli%20Zhang">Xiaoli Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiongfei%20Li"> Xiongfei Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuncong%20Feng"> Yuncong Feng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ROC curves, as a widely used evaluating tool in machine learning field, are the tradeoff of true positive rate and negative rate.

The channel hopping (CH) technique is a typical solution to this blind rendezvous problem. In this paper, we propose a quinary coding and matrix structure-based CH algorithm called QCMS-CH. The QCMS-CH algorithm can guarantee the rendezvous of users using only one cognitive radio in the scenario of the asynchronous clock (i.e., arbitrary time drift between the users), heterogeneous channels (i.e., the available channel sets of users are distinct), and symmetric role (i.e., all users play a same role). The QCMS-CH algorithm first represents a randomly selected channel (denoted by R) as a fixed-length quaternary number. Then it encodes the quaternary number into a quinary bootstrapping sequence according to a carefully designed quaternary-quinary coding table with the prefix "R00". Finally, it builds a CH matrix column by column according to the bootstrapping sequence and six different types of elaborately generated subsequences. The user can access the CH matrix row by row and accordingly perform its channel, hoping to attempt rendezvous with other users. We prove the correctness of QCMS-CH and derive an upper bound on its Maximum Time-to-Rendezvous (MTTR). Simulation results show that the QCMS-CH algorithm outperforms the state-of-the-art in terms of the MTTR and the Expected Time-to-Rendezvous (ETTR). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=channel%20hopping" title="channel hopping">channel hopping</a>, <a href="https://publications.waset.org/abstracts/search?q=blind%20rendezvous" title=" blind rendezvous"> blind rendezvous</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20radio%20networks" title=" cognitive radio networks"> cognitive radio networks</a>, <a href="https://publications.waset.org/abstracts/search?q=quaternary-quinary%20coding" title=" quaternary-quinary coding"> quaternary-quinary coding</a> </p> <a href="https://publications.waset.org/abstracts/153152/a-quinary-coding-and-matrix-structure-based-channel-hopping-algorithm-for-blind-rendezvous-in-cognitive-radio-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153152.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">266</span> Gender Differences in the Descriptions of Shape</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shu-Feng%20Chang">Shu-Feng Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the past years, gender issues have been discussed in many fields.

This statement was proved in the descriptions of color. However, the research about describing shape was fewer. The purpose of the study was to determine the description of the shape was different or alike due to gender. If it was different, this difference was dissimilar or as the same as the conclusion of color. Data were collected on the shape descriptions by 15 female and 15male participants in describing five pictures. As a result, it was really different for the descriptions of shape due to gender factor.

Although the estimation of the yaw angle has been extensively studied in existing literature, it is still the main challenge to simultaneously achieve a reliable and cost-effective solution in complex urban environments. This paper proposes a multi-stage learning framework to estimate the yaw angle with a monocular camera, which can deal with the challenge in a more reliable manner. In the first stage, an efficient road detection network is designed to extract the road region, providing a highly reliable reference for the estimation. In the second stage, a variational auto-encoder (VAE) is proposed to learn the distribution patterns of road regions, which is particularly suitable for modeling the changing patterns of yaw angle under different driving maneuvers, and it can inherently enhance the generalization ability. In the last stage, a gated recurrent unit (GRU) network is used to capture the temporal correlations of the learned patterns, which is capable to further improve the estimation accuracy due to the fact that the changes of deflection angle are relatively easier to recognize among continuous frames. Afterward, the yaw angle can be obtained by combining the estimated deflection angle and the road direction stored in a roadway map. Through effective multi-stage learning, the proposed framework presents high reliability while it maintains better accuracy. Road-test experiments with different driving maneuvers were performed in complex urban environments, and the results validate the effectiveness of the proposed framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gated%20recurrent%20unit" title="gated recurrent unit">gated recurrent unit</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-stage%20learning" title=" multi-stage learning"> multi-stage learning</a>, <a href="https://publications.waset.org/abstracts/search?q=reliable%20estimation" title=" reliable estimation"> reliable estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=variational%20auto-encoder" title=" variational auto-encoder"> variational auto-encoder</a>, <a href="https://publications.waset.org/abstracts/search?q=yaw%20angle" title=" yaw angle"> yaw angle</a> </p> <a href="https://publications.waset.org/abstracts/127783/a-multi-stage-learning-framework-for-reliable-and-cost-effective-estimation-of-vehicle-yaw-angle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127783.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">143</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">264</span> Numerical Study of a 6080HP Open Drip Proof (ODP) Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Feng-Hisang%20Lai">Feng-Hisang Lai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CFD(Computational Fluid Dynamics) is conducted to numerically study the flow and heat transfer features of a two-pole, 6,080HP, 60Hz, 3,150V open drip-proof (ODP) motor.

The results show that CO2-EGS system performance of power generation and power cost vary greatly among cases of different wells perforation locations, and the optimum options under different boundary conditions are also different. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enhanced%20Geothermal%20System" title="Enhanced Geothermal System">Enhanced Geothermal System</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20CO2" title=" supercritical CO2"> supercritical CO2</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2-EGS" title=" CO2-EGS"> CO2-EGS</a> </p> <a href="https://publications.waset.org/abstracts/2713/investigation-of-enhanced-geothermal-system-with-co2-as-working-fluid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2713.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">292</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">259</span> Theoretical BER Analyzing of MPSK Signals Based on the Signal Space</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing%20Qing-feng">Jing Qing-feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Danmei"> Liu Danmei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on the optimum detection, signal projection and Maximum A Posteriori (MAP) rule, Proakis has deduced the theoretical BER equation of Gray coded MPSK signals. Proakis analyzed the BER theoretical equations mainly based on the projection of signals, which is difficult to be understood. This article solve the same problem based on the signal space, which explains the vectors relations among the sending signals, received signals and noises. The more explicit and easy-deduced process is illustrated in this article based on the signal space, which can illustrated the relations among the signals and noises clearly. This kind of deduction has a univocal geometry meaning. It can explain the correlation between the production and calculation of BER in vector level. <p class="card-text"><strong>Keywords:</strong> <a
