While some technologies play a central role in developing technology, others play a secondary role. The role of the technological components can be classified as core or non-core (peripheral) technology. The core technologies have a considerable knowledge interaction with other technological components while the non-core technologies barely interact with others within the system. This study introduces the concept that classifies the technological components into core or peripheral technology according to their role and importance in the technology field. The study adapted the social network analysis to examine the relationship between technological components. Using a continuous core-periphery analysis, it identifies the technological network structure and classifies the core and peripheral nodes. Based on their knowledge inflow/outflow direction and their dependence/influence on core technologies, the technological clusters are classified into four categories: (1) high dependence and high influence on core technology, (2) high dependence and low influence on core technology, (3) low dependence and high influence on core technology, and (4) low dependence and low influence on core technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20technology" title="core technology">core technology</a>, <a href="https://publications.waset.org/abstracts/search?q=periphery%20technology" title=" periphery technology"> periphery technology</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20components" title=" technological components"> technological components</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20role" title=" technological role"> technological role</a> </p> <a href="https://publications.waset.org/abstracts/79729/classifying-the-role-of-technology-in-technology-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79729.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">538</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">9420</span> Study on Clarification of the Core Technology in a Monozukuri Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nishiyama%20Toshiaki">Nishiyama Toshiaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadayuki%20Kyountani"> Tadayuki Kyountani</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Huu%20Phuc"> Nguyen Huu Phuc</a>, <a href="https://publications.waset.org/abstracts/search?q=Shigeyuki%20Haruyama"> Shigeyuki Haruyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Oke%20Oktavianty"> Oke Oktavianty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is important to clarify the company’s core technology in product development process to strengthen their power in providing technology that meets the customer requirement.

We employ multi-level logistic regression modelling methods on a sub-sample of the Global Entrepreneurship Monitor’s 2011 survey covering 30 countries. The results reveal that employees who have experience with activities unrelated to the core technology of their organizations are more likely to spin out entrepreneurial ventures, whereas those with experiences related to the core technology are less likely to do so. In support of the recent theory, we find that the strength of intellectual property rights and the availability of venture capital have negative and positive effects, respectively, on the likelihood that employees turn into entrepreneurs. These institutional factors also moderate the effect of relatedness to core technology such that entrepreneurial entries by employees with experiences related to core technology are curbed more severely by stronger intellectual property rights protection regimes and lack of venture capital. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spinouts" title="spinouts">spinouts</a>, <a href="https://publications.waset.org/abstracts/search?q=intellectual%20property%20rights" title=" intellectual property rights"> intellectual property rights</a>, <a href="https://publications.waset.org/abstracts/search?q=venture%20capital" title=" venture capital"> venture capital</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title=" entrepreneurship"> entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20experiences" title=" organizational experiences"> organizational experiences</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20technology" title=" core technology"> core technology</a> </p> <a href="https://publications.waset.org/abstracts/37205/antecedents-of-spinouts-technology-relatedness-intellectual-property-rights-and-venture-capital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37205.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">356</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">9418</span> Seismic Behavior of Short Core Buckling Restrained Braces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nader%20Hoveidae">Nader Hoveidae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the seismic behavior of a new type of buckling restrained braces (BRBs) called "Short Core BRBs" in which a shorter core segment is used as an energy dissipating part and an elastic part is serially connected to the core. It seems that a short core BRB is easy to be fabricated, inspected and replaced after a severe earthquake. In addition, the energy dissipating capacity in a short core BRB is higher because of larger core strains. However, higher core strain demands result in high potential of low-cycle fatigue fracture. In this paper, a strategy is proposed to estimate the minimum core length in a short core BRBs. The seismic behavior of short core buckling restrained brace is experimentally examined. The results revealed that the short core buckling restrained brace is able to sustain large inelastic strains without any significant instability or strength degradation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=short%20core" title="short core">short core</a>, <a href="https://publications.waset.org/abstracts/search?q=Buckling%20Restrained%20Brace" title=" Buckling Restrained Brace"> Buckling Restrained Brace</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20test" title=" cyclic test"> cyclic test</a> </p> <a href="https://publications.waset.org/abstracts/37090/seismic-behavior-of-short-core-buckling-restrained-braces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37090.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">360</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">9417</span> NFC Kenaf Core Graphene Paper: In-situ Method Application </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Izzati">M.

The prepared QDs have been examined by using X-ray diffraction, high-resolution electron microscopy and optical spectroscopy. The photoluminescence (PL) quantum yield (QY) of core-shell QDs increases with respect to the core, indicating that the radiative rate increases by the formation of shell around core, as evident by the measurement of PL lifetime. Further, the PL of bovine serum albumin is quenched strongly by the presence of core-shall QDs and follow the Stern-Volmer (S-V) relation, whereas the lifetime does not follow the S-V relation, demonstrating that the observed quenching is predominantly static in nature. Among all the QDs, the CdSe/ZnS QDs shows the least cytotoxicity hence most biocompatibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocompatibility" title="biocompatibility">biocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=core-shell%20quantum%20dots" title=" core-shell quantum dots"> core-shell quantum dots</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence%20and%20lifetime" title=" photoluminescence and lifetime"> photoluminescence and lifetime</a>, <a href="https://publications.waset.org/abstracts/search?q=sensing%20ability" title=" sensing ability"> sensing ability</a> </p> <a href="https://publications.waset.org/abstracts/56638/biocompatibility-and-sensing-ability-of-highly-luminescent-synthesized-core-shell-quantum-dots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56638.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">236</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">9414</span> Local Buckling of Web-Core and Foam-Core Sandwich Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20N.%20Suri">Ali N.

It is a type of stressed skin construction formed by bonding two thin faces to a thick core, the faces resist all of the applied edge loads and provide all or nearly all of the required rigidities, the core spaces the faces to increase cross section moment of inertia about common neutral axis and transmit shear between them provides a perfect bond between core and faces is made. Material for face sheets can be of metal or reinforced plastics laminates, core material can be metallic cores of thin sheets forming corrugation or honeycomb, or non-metallic core of Balsa wood, plastic foams, or honeycomb made of reinforced plastics. For in plane axial loading web core and web-foam core Sandwich panels can fail by local buckling of plates forming the cross section with buckling wave length of the order of length of spacing between webs. In this study local buckling of web core and web-foam core Sandwich panels is carried out for given materials of facing and core, and given panel overall dimension for different combinations of cross section geometries.

Our government has issued a series of policies to guide and support the development of renewable energy. The implementation of these policies will affect the further development, utilization and technological innovation of renewable energy. In this context, it is of great significance to systematically sort out and evaluate the renewable energy technology innovation policy for improving the existing policy system. Taking the 190 renewable energy technology innovation policies issued during 2005-2021 as a sample, from the perspectives of policy issuing departments and policy keywords, it uses text mining and content analysis methods to analyze the current situation of the policies and conduct a semantic network analysis to identify the core issuing departments and core policy topic words; A PMC (Policy Modeling Consistency) index model is built to quantitatively evaluate the selected policies, analyze the overall pros and cons of the policy through its PMC index, and reflect the PMC value of the model's secondary index The core departments publish policies and the performance of each dimension of the policies related to the core topic headings. The research results show that Renewable energy technology innovation policies focus on synergy between multiple departments, while the distribution of the issuers is uneven in terms of promulgation time; policies related to different topics have their own emphasis in terms of policy types, fields, functions, and support measures, but It still needs to be improved, such as the lack of policy forecasting and supervision functions, the lack of attention to product promotion, and the relatively single support measures. Finally, this research puts forward policy optimization suggestions in terms of promoting joint policy release, strengthening policy coherence and timeliness, enhancing the comprehensiveness of policy functions, and enriching incentive measures for renewable energy technology innovation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy%20technology%20innovation" title="renewable energy technology innovation">renewable energy technology innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=content%20analysis" title=" content analysis"> content analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20evaluation" title=" policy evaluation"> policy evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=PMC%20index%20model" title=" PMC index model"> PMC index model</a> </p> <a href="https://publications.waset.org/abstracts/175552/research-on-evaluation-of-renewable-energy-technology-innovation-strategy-based-on-pmc-index-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175552.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">64</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">9412</span> Identification of Transformer Core Vibrations and the Effect of Third Harmonic in the Electricity Grid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Setareh%20Gorji%20Ghalamestani">Setareh Gorji Ghalamestani</a>, <a href="https://publications.waset.org/abstracts/search?q=Lieven%20Vandevelde"> Lieven Vandevelde</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Melkebeek"> Jan Melkebeek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, an experimental technique is applied for the measurements of the vibrations and deformation of a test transformer core.

Core strength means to strengthen the muscles deep within the abdomen which connect to the spine and pelvis which control the position and movement of the central portion of the body. Strengthening of core muscles is important for injury prevention (lower back pain) and performance enhancement in sports. The purpose of the study was to review the literature and findings on the effects of Yoga exercise as a part of sports training method and fitness programs. Fifteen papers were found to be relevant for this review. There are five simple yoga poses: Ardha Phalakasana (Low plank), Vasisthasana (side plank), Purvottanasana (inclined plane), Sarvangasana (shoulder stand), and Virabhadrasana (Warrior) are found to be very effective for strengthening core muscles. They are the most effective poses to build core strength and flexibility to the core muscles. The study suggests that sports and fitness trainers should include these yoga exercises in their programs to strengthen core muscles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20strength" title="core strength">core strength</a>, <a href="https://publications.waset.org/abstracts/search?q=yoga" title=" yoga"> yoga</a>, <a href="https://publications.waset.org/abstracts/search?q=injuries" title=" injuries"> injuries</a>, <a href="https://publications.waset.org/abstracts/search?q=lower%20back" title=" lower back"> lower back</a> </p> <a href="https://publications.waset.org/abstracts/57946/a-comprehensive-review-of-yoga-and-core-strength-strengthening-core-muscles-as-important-method-for-injury-prevention-lower-back-pain-and-performance-enhancement-in-sports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57946.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">276</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">9410</span> Effect of Core Puncture Diameter on Bio-Char Kiln Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Intagun">W.

Product yields produced from biochar kiln are dependent on process parameters and kiln types used. The objective of this research is to investigate the effect of core puncture diameter on biochar kiln efficiency, i.e., yields of biochar and produced gas. Corncobs were used as raw material to produce biochar. Briquettes from agricultural wastes were used as fuel. Each treatment was performed by changing the core puncture diameter. From the experiment, it is revealed that the yield of biochar at the core puncture diameter of 3.18 mm, 4.76 mm, and 6.35 mm was 10.62 wt. %, 24.12 wt. %, and 12.24 wt. %, of total solid yields, respectively. The yield of produced gas increased with increasing the core puncture diameter. The maximum percentage by weight of the yield of produced gas was 81.53 wt. % which was found at the core puncture diameter of 6.35 mm. The core puncture diameter was furthermore found to affect the temperature distribution inside the kiln and its thermal efficiency. In conclusion, the high efficient biochar kiln can be designed and constructed by using the proper core puncture diameter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anila%20stove" title="anila stove">anila stove</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-char" title=" bio-char"> bio-char</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20conditioning%20materials" title=" soil conditioning materials"> soil conditioning materials</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20distribution" title=" temperature distribution"> temperature distribution</a> </p> <a href="https://publications.waset.org/abstracts/90969/effect-of-core-puncture-diameter-on-bio-char-kiln-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90969.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">231</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">9409</span> Microstructural Investigations of Metal Oxides Encapsulated Thermochromic Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Emirov">Yusuf Emirov</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullatif%20Hakami"> Abdullatif Hakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanta%20K%20Biswas"> Prasanta K Biswas</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20K%20Stefanakos"> Elias K Stefanakos</a>, <a href="https://publications.waset.org/abstracts/search?q=Sesha%20S%20Srinivasan"> Sesha S Srinivasan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is aimed to develop microencapsulated thermochromic materials and the analysis of core-shell formation using high resolution electron microscopy.

The beam consists of two carbon/epoxy composite face sheets, aluminum honeycomb core, and rubber core to enhance the repeated low-velocity impact resistance of sandwich structures. This paper aims to numerically enhance the repeated low-velocity impact resistance of the BHSB via optimizing the aluminum honeycomb core thickness. The beam was investigated employing three core thicknesses: 20 mm, 25 mm, and 30 mm at three impact energy levels (13.5 J, 15.55 J, 21.43 J). The results revealed that increasing the thickness of the aluminum honeycomb core to a certain level enhances the sandwich beam stiffness. The beam with the 25 mm honeycomb core thickness was the only beam that can sustain five repeated impacts achieving the highest impact resistance efficiency index, especially at high energy levels. Furthermore, the bottom face sheet of this beam developed the lowest stresses indicating that this thickness has a relatively better performance during impact events since it allowed minimal stress to reach the bottom face sheet. Overall, increasing the aluminum core thickness will increase the height of its cells subjecting it to buckling phenomenon. Therefore, this study suggests that the optimal thickness of the aluminum honeycomb core should be 65 % of the overall thickness of the sandwich beam to have the best impact resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sandwich%20beams" title="sandwich beams">sandwich beams</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20thickness" title=" core thickness"> core thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20behavior" title=" impact behavior"> impact behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling "> modeling </a> </p> <a href="https://publications.waset.org/abstracts/113735/the-effect-of-honeycomb-core-thickness-on-the-repeated-low-velocity-impact-behavior-of-sandwich-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113735.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">9406</span> Synthesis of Nano Iron Copper Core-Shell by Using K-M Reactor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ahmed%20AbdelKawy">Mohamed Ahmed AbdelKawy</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20El-Shazly"> A.

The reaction between nano-pure iron with copper sulphate pentahydrate (CuSO4.5H2O) beside NaCMC as a stabilizer at K-M reactor gives many advantages in comparison with the traditional chemical method for production of nano iron-Copper core-shell in batch reactor. Many factors were investigated for its effect on the process performance such as initial concentrations of nano iron and copper sulphate pentahydrate solution. Different techniques were used for investigation and characterization of the produced nano iron particles such as SEM, XRD, UV-Vis, XPS, TEM and PSD. The produced Nano iron-copper core-shell particle using micro mixer showed better characteristics than those produced using batch reactor in different aspects such as homogeneity of the produced particles, particle size distribution and size, as core diameter 10nm particle size were obtained.

With student employment rate as an important indicator for University Program Evaluation periodically held by the Ministry of Education, it becomes extremely critical for a university to build up a teaching and learning quality assurance system to bridge the gap between learning and practice. Teaching and Learning Quality Assurance System has been built and implemented at Chaoyang University of Technology for years and has received substantial results. By employing various forms of evaluation and performance appraisals, the effectiveness of teaching and learning can consistently be tracked as a means of ensuring teaching and learning quality. This study aims to explore the evaluation system of teaching and learning quality assurance system at the Chaoyang University of Technology by means of content analysis. The study contents the evaluation reports on the teaching and learning quality assurance at the Chaoyang University of Technology in the Academic Year 2013-2015. The quantitative results of the assessment were analyzed using the five-point Likert Scale. Quality assurance Committee meetings were further held for examining and discussions on the results. To the end, the annual evaluation report is to be produced as references used to improve approaches in both teaching and learning. The findings indicate that there is a respective relationship between the overall teaching evaluation items and the teaching goals and core competencies. In addition, graduates’ feedbacks were also collected for further analysis to examine if the current educational planning is able to achieve the university’s teaching goal and cultivation of core competencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20competencies" title="core competencies">core competencies</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20and%20learning%20quality%20assurance%20system" title=" teaching and learning quality assurance system"> teaching and learning quality assurance system</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20goals" title=" teaching goals"> teaching goals</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20program%20evaluation" title=" university program evaluation"> university program evaluation</a> </p> <a href="https://publications.waset.org/abstracts/72831/the-implementation-of-teaching-and-learning-quality-assurance-system-at-the-chaoyang-university-of-technology-for-academic-year-2013-2015" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72831.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">290</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">9404</span> Phase Transition in Iron Storage Protein Ferritin </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Navneet%20Kaur">Navneet Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20D.%20Tiwari"> S.

It has an antiferromagnetic iron core, 7-8 nm in size, which is encapsulated inside a protein cage. The thickness of this protein shell is about 2-3 nm. This protein shell reduces the interaction among particles and make ferritin a model superparamagnet. The major composition of ferritin core is mineral ferrihydrite. The molecular formula of ferritin core is (FeOOH)8[FeOOPO3H2]. In this study, we discuss the phase transition of ferritin. We characterized ferritin using x-ray diffractometer, transmission electron micrograph, thermogravimetric analyzer and vibrating sample magnetometer. It is found that ferritin core is amorphous in nature with average particle size of 8 nm. The thermogravimetric and differential thermogravimetric analysis curves shows mass loss at different temperatures. We heated ferritin at these temperatures. It is found that ferritin core starts decomposing after 390^o C. At 1020^o C, the ferritin core is finally converted to alpha phase of iron oxide. Magnetization behavior of final sample clearly shows the iron oxyhydroxide core is completely converted to alpha iron oxide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antiferromagnetic" title="Antiferromagnetic">Antiferromagnetic</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferritin" title=" Ferritin"> Ferritin</a>, <a href="https://publications.waset.org/abstracts/search?q=Phase" title=" Phase"> Phase</a>, <a href="https://publications.waset.org/abstracts/search?q=Superparamagnetic" title=" Superparamagnetic"> Superparamagnetic</a> </p> <a href="https://publications.waset.org/abstracts/124547/phase-transition-in-iron-storage-protein-ferritin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124547.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">119</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">9403</span> Investigating what Effects Aviation Fluids Have on the Flatwise Compressive Strength of Nomex® Honeycomb Core Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Kim">G.

The test specimens were manufactured of fiberglass prepreg for the facesheets and Nomex<sup>®</sup> honeycomb core for the core material in accordance with ASTM C-365/365M. Test specimens were soaked in several different kinds of fluids, such as aircraft fuel, turbine engine oil, hydraulic fluid, and water for a period of 60 days. A flatwise compressive test was performed, and the test results were analyzed to determine how the contact with aircraft fluids affected the compressive strength of the Nomex<sup>®</sup> honeycomb core and how the strength was recovered when the specimens were dry. In addition, the investigation of de-bonding between facesheet and core material after soaking were performed to support the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sandwich%20structure" title="sandwich structure">sandwich structure</a>, <a href="https://publications.waset.org/abstracts/search?q=honeycomb" title=" honeycomb"> honeycomb</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20degradation" title=" environmental degradation"> environmental degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=debonding" title=" debonding"> debonding</a> </p> <a href="https://publications.waset.org/abstracts/100894/investigating-what-effects-aviation-fluids-have-on-the-flatwise-compressive-strength-of-nomex-honeycomb-core-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100894.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">177</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">9402</span> Modeling Core Flooding Experiments for Co₂ Geological Storage Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avinoam%20Rabinovich">Avinoam Rabinovich</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO₂ geological storage is a proven technology for reducing anthropogenic carbon emissions, which is paramount for achieving the ambitious net zero emissions goal. Core flooding experiments are an important step in any CO₂ storage project, allowing us to gain information on the flow of CO₂ and brine in the porous rock extracted from the reservoir. This information is important for understanding basic mechanisms related to CO₂ geological storage as well as for reservoir modeling, which is an integral part of a field project. In this work, a different method for constructing accurate models of CO₂-brine core flooding will be presented. Results for synthetic cases and real experiments will be shown and compared with numerical models to exhibit their predictive capabilities. Furthermore, the various mechanisms which impact the CO₂ distribution and trapping in the rock samples will be discussed, and examples from models and experiments will be provided. The new method entails solving an inverse problem to obtain a three-dimensional permeability distribution which, along with the relative permeability and capillary pressure functions, constitutes a model of the flow experiments. The model is more accurate when data from a number of experiments are combined to solve the inverse problem. This model can then be used to test various other injection flow rates and fluid fractions which have not been tested in experiments. The models can also be used to bridge the gap between small-scale capillary heterogeneity effects (sub-core and core scale) and large-scale (reservoir scale) effects, known as the upscaling problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20geological%20storage" title="CO₂ geological storage">CO₂ geological storage</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20trapping" title=" residual trapping"> residual trapping</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary%20heterogeneity" title=" capillary heterogeneity"> capillary heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20flooding" title=" core flooding"> core flooding</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82-brine%20flow" title=" CO₂-brine flow"> CO₂-brine flow</a> </p> <a href="https://publications.waset.org/abstracts/169584/modeling-core-flooding-experiments-for-co2-geological-storage-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169584.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">70</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">9401</span> Advances in Fiber Optic Technology for High-Speed Data Transmission</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salim%20Yusif">Salim Yusif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fiber optic technology has revolutionized telecommunications and data transmission, providing unmatched speed, bandwidth, and reliability.

However, determining ideal structural configurations remains challenging. This chapter compares the compression properties of flax fiber-reinforced polylactic acid (PLA) of empty honeycomb core, foam-filled honeycomb and double cell wall square interlocking core sandwich structure under quasi-static compression loading. The square interlocking core is fabricated through a slotting technique, whereas the honeycomb core is made using a corrugated mold that was initially used to create the corrugated core composite profile, which is then cut into corrugated webs and assembled to form the honeycomb core. The sandwich structures are tested at a crosshead displacement rate of 2 mm/min. The experimental results showed that honeycomb outperformed the square interlocking core in terms of their strength capability and SEA by around 14% and 34%, respectively. It is observed that the foam-filled honeycomb collapse in a progressive mode, exhibiting noticeable advantages over the empty honeycomb; this is attributed to the interaction between the honeycomb wall and foam filler. Interestingly, the average SEAs of foam-filled and empty honeycomb cores have no significant difference, around 8.7kJ/kg and 8.2kJ/kg, respectively. In contrast, its strength capability is clearly pronounced, in which the foam-filled core outperforms the empty counterparts by around 33%. Finally, the results for empty and foam-filled cores were significantly superior to aluminum cores published in the literature. <p class="card-text"><strong>Keywords:</strong> <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=flax" title=" flax"> flax</a>, <a href="https://publications.waset.org/abstracts/search?q=honeycomb%20core" title=" honeycomb core"> honeycomb core</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20energy%20absorption" title=" specific energy absorption"> specific energy absorption</a> </p> <a href="https://publications.waset.org/abstracts/166700/on-compression-properties-of-honeycomb-structures-using-flaxpla-composite-as-core-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166700.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">83</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">9399</span> Diagnostic Accuracy Of Core Biopsy In Patients Presenting With Axillary Lymphadenopathy And Suspected Non-Breast Malignancy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monisha%20Edirisooriya">Monisha Edirisooriya</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilma%20Jack"> Wilma Jack</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Twelves">Dominique Twelves</a>, <a href="https://publications.waset.org/abstracts/search?q=Jennifer%20Royds"> Jennifer Royds</a>, <a href="https://publications.waset.org/abstracts/search?q=Fiona%20Scott"> Fiona Scott</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Mason"> Nicola Mason</a>, <a href="https://publications.waset.org/abstracts/search?q=Arran%20Turnbull"> Arran Turnbull</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Michael%20Dixon"> J.

Core biopsy of nodes can provide sufficient tissue for diagnosis and has advantages in terms of morbidity and speed of diagnosis. This study evaluates the diagnostic accuracy of core biopsy in patients presenting with axillary lymphadenopathy. Methods: Between 2009 and 2019, 165 patients referred to the Edinburgh Breast Unit had a total of 179 axillary lymph node core biopsies. Results: 152 (92%) of the 165 initial core biopsies were deemed to contain adequate nodal tissue. Core biopsy correctly established malignancy in 75 of the 78 patients with haematological malignancy (96%) and in all 28 patients with metastatic carcinoma (100%) and correctly diagnosed benign changes in 49 of 57 (86%) patients with benign conditions. There were no false positives and no false negatives. In 67 (85.9%) of the 78 patients with hematological malignancy, there was sufficient material in the first core biopsy to allow the pathologist to make an actionable diagnosis and not ask for more tissue sampling prior to treatment. There were no complications of core biopsy. On follow up, none of the patients with benign cores has been shown to have malignancy in the axilla and none with lymphoma had their initial disease incorrectly classified. Conclusions: This study shows that core biopsy is now the investigation of choice for patients presenting with axillary lymphadenopathy even in those suspected as having lymphoma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20biopsy" title="core biopsy">core biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=excision%20biopsy" title=" excision biopsy"> excision biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=axillary%20lymphadenopathy" title=" axillary lymphadenopathy"> axillary lymphadenopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=non-breast%20malignancy" title=" non-breast malignancy"> non-breast malignancy</a> </p> <a href="https://publications.waset.org/abstracts/141187/diagnostic-accuracy-of-core-biopsy-in-patients-presenting-with-axillary-lymphadenopathy-and-suspected-non-breast-malignancy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141187.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">241</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">9398</span> Natural Emergence of a Core Structure in Networks via Clique Percolation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Melka">A.

An alternative view of graphs is through communities. Multiple measures have been proposed for dense communities in graphs, the most classical being k-cliques, k-cores, and k-plexes, all presenting groups of tightly connected vertices. We here show that the edge number thresholds for such communities to emerge and for their percolation into a single dense connectivity component are very close, in all networks studied. These percolating cliques produce a natural core and periphery structure. This result is generic and is tested in configuration models and in real-world networks. This is also true for k-cores and k-plexes. Thus, the emergence of this connectedness among communities leading to a core is not dependent on some specific mechanism but a direct result of the natural percolation of dense communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cliques" title="cliques">cliques</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20structure" title=" core structure"> core structure</a>, <a href="https://publications.waset.org/abstracts/search?q=percolation" title=" percolation"> percolation</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20transition" title=" phase transition"> phase transition</a> </p> <a href="https://publications.waset.org/abstracts/102098/natural-emergence-of-a-core-structure-in-networks-via-clique-percolation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102098.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">171</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">9397</span> Social Discussion Networks during the Covid-19 Pandemic: A Study of College Students Core Discussion Groups</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Regan%20Harper">Regan Harper</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%20Yang"> Song Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Douglas%20Adams"> Douglas Adams</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the historically unprecedent time of Covid-19 pandemic, we survey college students with social issue generators to measure their core discussion groups.

The core discussion groups of our sample are very gender balanced, with female alters slightly outnumbering male alters. However, the core discussion groups are racially homogenous, consisting of mostly white students (around or above 80 percent).

The sample permeability coefficients were determined under conditions of confining pressure from 5 MPa to 35 MPa. These studies showed that at a confining pressure of 35 MPa – corresponding to a depth of about 1000 m, the shale core was impermeable in the direction perpendicular to the bedding, and in the direction parallel to the bedding, the sample had very low permeability (k∞=0.001 mD). The sorption tests performed showed low sorption capacities, which amounted to a maximum of 1.28 cm³/g in relation to CO₂ and 0.87 cm³/g to CH₄ at a pressure of 1.4 MPa. The most important study used to assess the possibilities of CO₂ storage and gas recovery from shale rocks were the CO₂/CH₄ exchange experiments, which were carried out under confining pressure conditions of 5 MPa and 30 MPa. These experiments were carried out on a unique apparatus, which makes it possible to apply a confining pressure corresponding to in situ conditions. The obtained results made it possible to carry out a comprehensive balance of gas exchange during the injection of CO₂ into the shale sample, with simultaneous recovery of CH₄. Based on the conducted sorption and gas exchange studies on the core sample under confining pressure conditions, it was found that in situ conditions, at the depths of shale gas occurrence in Poland of 3000-4000 m, where the confining pressure can be about 100 MPa: (i) poorly developed pore structure, (ii) very low permeability, and (iii) low sorption properties, make shale rocks poorly predisposed to the application of CO₂ storage technology with simultaneous recovery of CH₄. Without the stimulation of CO₂/CH₄ exchange rates through fracturing processes, the effectiveness of CO₂-ESGR technology on shale rock is very low. The research presented in this work is extremely important from the point of view of precise assessment of the potential of CO₂-ESGR technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shale%20gas" title="shale gas">shale gas</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20rocks" title=" shale rocks"> shale rocks</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%2FCH%E2%82%84%20exchange" title=" CO₂/CH₄ exchange"> CO₂/CH₄ exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=permeability" title=" permeability"> permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=sorption" title=" sorption"> sorption</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82" title=" CO₂"> CO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=CH%E2%82%84" title=" CH₄"> CH₄</a> </p> <a href="https://publications.waset.org/abstracts/194521/co2ch4-exchange-studies-on-shales-to-assess-the-potential-for-co2-storage-and-enhanced-shale-gas-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194521.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">11</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">9394</span> Core Loss Influence on MTPA Current Vector Variation of Synchronous Reluctance Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huai-Cong%20Liu">Huai-Cong Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Chul%20Jeong"> Tae Chul Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Lee"> Ju Lee </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to develop an electric circuit method (ECM) to ascertain the core loss influence on a Synchronous Reluctance Motor (SynRM) in the condition of the maximum torque per ampere (MTPA). SynRM for fan usually operates on the constant torque region, at synchronous speed the MTPA control is adopted due to current vector. However, finite element analysis (FEA) program is not sufficient exactly to reflect how the core loss influenced on the current vector. This paper proposed a method to calculate the current vector with consideration of core loss. The precision of current vector by ECM is useful for MTPA control. The result shows that ECM analysis is closer to the actual motor’s characteristics by testing with a 7.5kW SynRM drive System. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20loss" title="core loss">core loss</a>, <a href="https://publications.waset.org/abstracts/search?q=SynRM" title=" SynRM"> SynRM</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20vector" title=" current vector"> current vector</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20saturation" title=" magnetic saturation"> magnetic saturation</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20torque%20per%20ampere%20%28MTPA%29" title=" maximum torque per ampere (MTPA)"> maximum torque per ampere (MTPA)</a> </p> <a href="https://publications.waset.org/abstracts/25312/core-loss-influence-on-mtpa-current-vector-variation-of-synchronous-reluctance-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25312.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">530</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">9393</span> Generation of Mesoporous Silica Shell onto SSZ-13 and Its Effects on Methanol to Olefins</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying%20Weiyong">Ying Weiyong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The micro/mesoporous core-shell composites compromising SSZ-13 cores and mesoporous silica shells were synthesized successfully with the soft template of cetytrimethylammonium. The shell thickness could be tuned from 25 nm to 100 nm by varying the TEOS/SSZ-13 ratio. The BET and SEM results show the core-shell composites possessing the tunable surface area (544.7-811.0 m2/g) with plenty of mesopores (2.7 nm). The acidity intensity of the strong acid sites on SSZ-13 was remarkably impaired with the decoration of the mesoporous silica shell, which leads to the suppression of the hydrogen transfer reaction in MTO reaction. The micro/mesoporous core-shell composites exhibit better methanol to olefins reaction performance with a prolonged lifetime and the improvement of light olefins selectivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core-shell" title="core-shell">core-shell</a>, <a href="https://publications.waset.org/abstracts/search?q=mesoporous%20silica" title=" mesoporous silica"> mesoporous silica</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol%20to%20olefins" title=" methanol to olefins"> methanol to olefins</a>, <a href="https://publications.waset.org/abstracts/search?q=SSZ-13" title=" SSZ-13"> SSZ-13</a> </p> <a href="https://publications.waset.org/abstracts/120695/generation-of-mesoporous-silica-shell-onto-ssz-13-and-its-effects-on-methanol-to-olefins" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120695.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">163</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">9392</span> Buckling Resistance of GFRP Sandwich Infill Panels with Different Cores under Increased Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=WooYoung%20Jung">WooYoung Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20Sim"> V. Sim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents numerical analysis in terms of buckling resistance strength of polymer matrix composite (PMC) infill panels system under the influence of temperature on the foam core. Failure mode under in-plane compression is investigated by means of numerical analysis with ABAQUS platform. Parameters considered in this study are contact length and both the type of foam for core and the variation of its Young's Modulus under the thermal influence. Variation of temperature is considered in static cases and only applied to core. Indeed, it is shown that the effect of temperature on the panel system mechanical properties is significance. Moreover, the variations of temperature result in the decrements of the system strength. This is due to the polymeric nature of this material. Additionally, the contact length also displays the effect on performance of infill panel. Their significance factors are based on type of polymer for core. Hence, by comparing difference type of core material, the variation can be reducing. <p class="card-text"><strong>Keywords:</strong> <a
