effect of asymmetric information on the composition of capital inflows. This study uses the stock market microstructure to capture the asymmetric information. Such an approach allows one to capture the level and extent of the asymmetric information from a firm’s perspective. This study focuses on the two-dimensional measure of the market microstructure in capturing asymmetric information. The composition of capital inflows is measured by running six models simultaneously. By employing the panel data technique, the main finding of this research shows an increase in the asymmetric information of the stock market, in any of the two dimensions of width and depth. This leads to the reduction of foreign investments in both forms of foreign portfolio investment (FPI) and foreign direct investment (FDI), while the reduction in FPI is higher than that of the FDI. The significant effect of asymmetric information on capital inflows implicitly suggests for policymakers to control the changes of foreign capital inflows through transparency in the level of the market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capital%20flows%20composition" title="capital flows composition">capital flows composition</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20information" title=" asymmetric information"> asymmetric information</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20market%20microstructure" title=" stock market microstructure"> stock market microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20portfolio%20investment" title=" foreign portfolio investment"> foreign portfolio investment</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20direct%20investment" title=" foreign direct investment "> foreign direct investment </a> </p> <a href="https://publications.waset.org/abstracts/28871/asymmetric-information-and-composition-of-capital-inflows-stock-market-microstructure-analysis-of-asia-pacific-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28871.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">364</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">726</span> Development of Ultrasounf Probe Holder for Automatic Scanning Asymmetric Reflector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabilah%20Ibrahim">Nabilah Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Mohd%20Zaini"> Hafiz Mohd Zaini</a>, <a href="https://publications.waset.org/abstracts/search?q=Wan%20Fatin%20Liyana%20Mutalib"> Wan Fatin Liyana Mutalib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ultrasound equipment or machine is capable to scan in two dimensional (2D) areas.

Asymmetric rolling is a very effective way to create ultrafine-grained structures of metals and alloys. Since the asymmetric rolling is a continuous process, it has great potential for industrial production of ultrafine-grained structure sheets. Basic principles of asymmetric rolling are described in detail in scientific literature. In this work finite element modeling of asymmetric rolling and metal forming processes in multiroll gauge was performed. Parameters of the processes which allow achieving significant values of shear strain were defined. The results of the study will be useful for the research of the evolution of ultra-fine metal structure in asymmetric rolling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20rolling" title="asymmetric rolling">asymmetric rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalent%20strain" title=" equivalent strain"> equivalent strain</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=multiroll%20gauge" title=" multiroll gauge"> multiroll gauge</a>, <a href="https://publications.waset.org/abstracts/search?q=profile" title=" profile"> profile</a>, <a href="https://publications.waset.org/abstracts/search?q=severe%20plastic%20deformation" title=" severe plastic deformation"> severe plastic deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strain" title=" shear strain"> shear strain</a>, <a href="https://publications.waset.org/abstracts/search?q=sheet" title=" sheet"> sheet</a> </p> <a href="https://publications.waset.org/abstracts/6490/influence-of-different-asymmetric-rolling-processes-on-shear-strain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6490.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">265</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">724</span> Does Stock Markets Asymmetric Information Affect Foreign Capital Flows?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farid%20Habibi%20Tanha">Farid Habibi Tanha</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Jahanbazi"> Mojtaba Jahanbazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Foroutan"> Morteza Foroutan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasidah%20Mohd%20Rashid"> Rasidah Mohd Rashid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper depicts the effects of asymmetric information in determining capital inflows to be captured through stock market microstructure. The model can explain several stylized facts regarding the capital immobility. The first phase of the research involves in collecting and refining 150,000,000 daily data of 11 stock markets over a period of one decade in an effort to minimize the impact of survivorship bias. Three micro techniques were used to measure information asymmetries. The final phase analyzes the model through panel data approach. As a unique contribution, this research will provide valuable information regarding negative effects of information asymmetries in stock markets on attracting foreign investments. The results of this study can be directly considered by policy makers to monitor and control changes of capital flow in order to keep market conditions in a healthy manner, by preventing and managing possible shocks to avoid sudden reversals and market failures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20information" title="asymmetric information">asymmetric information</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20inflow" title=" capital inflow"> capital inflow</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20microstructure" title=" market microstructure"> market microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=investment" title=" investment"> investment</a> </p> <a href="https://publications.waset.org/abstracts/28872/does-stock-markets-asymmetric-information-affect-foreign-capital-flows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28872.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">321</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">723</span> The General Trend of FDI and the Effects of These Investments for Countries: 2000-2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esra%20Cebeci">Esra Cebeci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a result of acceleration of globalization in the 21st century economic boundaries are removed. With liberalization of capital and foreign trade, not only developed countries but also developing countries get into rapid growth efforts. In developing countries, one of the most important problem is insufficient capital accumulation. For reduce this deficit, one of the general approaches that is offered increasing amount of foreign direct investments. Also, in developing countries saving rates are low. So, foreign direct investments make possible an increase for domestic savings. In this regard, the multinational corporations are capable of these investments have importance. By providing micro-macro effects for countries, demand for these firms are many. These effects in general positive, some negative effects may able to come into being especially for developing countries. Foreign direct investments are performed buying an existing corporation, merging or greenfield investments. In recent, foreign direct investments are performed as a green field investments for developing countries. The study aims to analysis foreign direct investment trends for 2000-2013 years. In the first part of this study, the importance of foreign direct investments and their determinants are explained. In the second part, the article also shows that comparative analysis of the inward and outward investments for developing and developed countries. In conclusion, while developed countries can stand competition against other countries with these investments, developing countries can provide a sustainable growth with capital inflows. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foreign%20direct%20investments" title="foreign direct investments">foreign direct investments</a>, <a href="https://publications.waset.org/abstracts/search?q=multinational%20corporations" title=" multinational corporations"> multinational corporations</a>, <a href="https://publications.waset.org/abstracts/search?q=determinants%20of%20FDI" title=" determinants of FDI"> determinants of FDI</a>, <a href="https://publications.waset.org/abstracts/search?q=FDI%20trend" title=" FDI trend "> FDI trend </a> </p> <a href="https://publications.waset.org/abstracts/25319/the-general-trend-of-fdi-and-the-effects-of-these-investments-for-countries-2000-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25319.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">404</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">722</span> Asymmetrical Informative Estimation for Macroeconomic Model: Special Case in the Tourism Sector of Thailand </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chukiat%20Chaiboonsri">Chukiat Chaiboonsri</a>, <a href="https://publications.waset.org/abstracts/search?q=Satawat%20Wannapan"> Satawat Wannapan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper used an asymmetric informative concept to apply in the macroeconomic model estimation of the tourism sector in Thailand. The variables used to statistically analyze are Thailand international and domestic tourism revenues, the expenditures of foreign and domestic tourists, service investments by private sectors, service investments by the government of Thailand, Thailand service imports and exports, and net service income transfers. All of data is a time-series index which was observed between 2002 and 2015. Empirically, the tourism multiplier and accelerator were estimated by two statistical approaches. The first was the result of the Generalized Method of Moments model (GMM) based on the assumption which the tourism market in Thailand had perfect information (Symmetrical data). The second was the result of the Maximum Entropy Bootstrapping approach (MEboot) based on the process that attempted to deal with imperfect information and reduced uncertainty in data observations (Asymmetrical data). In addition, the tourism leakages were investigated by a simple model based on the injections and leakages concept. The empirical findings represented the parameters computed from the MEboot approach which is different from the GMM method. However, both of the MEboot estimation and GMM model suggests that Thailand’s tourism sectors are in a period capable of stimulating the economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TThailand%20tourism" title="TThailand tourism">TThailand tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=Maximum%20Entropy%20Bootstrapping%20approach" title=" Maximum Entropy Bootstrapping approach"> Maximum Entropy Bootstrapping approach</a>, <a href="https://publications.waset.org/abstracts/search?q=macroeconomic%20model" title=" macroeconomic model"> macroeconomic model</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20information" title=" asymmetric information"> asymmetric information</a> </p> <a href="https://publications.waset.org/abstracts/57039/asymmetrical-informative-estimation-for-macroeconomic-model-special-case-in-the-tourism-sector-of-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57039.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">295</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">721</span> Cryptosystems in Asymmetric Cryptography for Securing Data on Cloud at Various Critical Levels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sartaj%20Singh">Sartaj Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amar%20Singh"> Amar Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashok%20Sharma"> Ashok Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandeep%20Kaur"> Sandeep Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With upcoming threats in a digital world, we need to work continuously in the area of security in all aspects, from hardware to software as well as data modelling.

Cryptography has always been employed to avoid access to important data by using many processes. Symmetric key and asymmetric key cryptography have been used for keeping data secrets at rest as well in transmission mode. Various cryptosystems have evolved from time to time to make the data more secure.

Without these investments these parks assume not to be a very competitive and appealing daytrip for their target audiences. However, the impact of investments in attracting new visitors is not well-known and seems to differ dramatically between parks. This paper presents a case study from the Netherlands in which a small amusement park applied a suggested, not yet proven, investment method. The results of the investment are discussed in (a) the form of return on investment and (b) the success of the predictions with regard to this investment.

In the past, asymmetric powers of errors in the conditionally heteroskedastic models have been used to capture this effect. Our model is using the gamma difference representation of the generalized Laplace distributions that efficiently models the asymmetry. It has one additional natural parameter, the shape, that is used instead of power in the asymmetric power models to capture the strength of a long-lasting effect of shocks. Some fundamental properties of the model are provided including the formula for covariances and an explicit form for the conditional distribution of 'bad' and 'good' news processes given the past the property that is important for the statistical fitting of the model.

Using a dyadic panel dataset of asymmetric double tax treaties between 2005 and 2019, this study suggests first that the difference between domestic and negotiated WHTs on portfolio dividends is higher when the OECD member uses the credit method, as compared to when it uses the exemption method. Second, results suggest that the inclusion of tax-sparing provisions vanishes the positive effect of the credit method at home on the difference between domestic and negotiated WHTs on portfolio dividends, incentivizing developing countries to negotiate higher withholding taxes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=double%20tax%20treaties" title="double tax treaties">double tax treaties</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20investments" title=" asymmetric investments"> asymmetric investments</a>, <a href="https://publications.waset.org/abstracts/search?q=withholding%20tax" title=" withholding tax"> withholding tax</a>, <a href="https://publications.waset.org/abstracts/search?q=dividends" title=" dividends"> dividends</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20tax%20relief%20method" title=" double tax relief method"> double tax relief method</a>, <a href="https://publications.waset.org/abstracts/search?q=tax%20sparing" title=" tax sparing"> tax sparing</a> </p> <a href="https://publications.waset.org/abstracts/162832/tax-treaties-between-developed-and-developing-countries-withholding-taxes-and-treaty-heterogeneity-content" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162832.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">717</span> Chiral Diphosphine Ligands and Their Transition Metal Diphosphine Complexes in Asymmetric Catalysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shannen%20Lorraine">Shannen Lorraine</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Maragh"> Paul Maragh</a>, <a href="https://publications.waset.org/abstracts/search?q=Tara%20Dasgupta"> Tara Dasgupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamaluddin%20Abdur-Rashid"> Kamaluddin Abdur-Rashid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> (R)-(4,4',6,6'-tetramethoxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (R-Ph-Garphos), and (S)-(4,4',6,6'-tetramethoxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (S-Ph-Garphos) are novel, nucleophilic, chiral atropisomeric ligands. The research explored the synthesis of chiral transition metal complexes containing these ligands and their applications in various asymmetric catalytic transformations. Herein, the transition metal complexes having ruthenium(II), rhodium(I) and iridium(I) metal centres will be discussed. These are air stable complexes and were characterized by CHN analysis, 1H, 13C, and 31P NMR spectroscopy, and polarimetry. Currently, there is an emphasis on 'greener' catalysts and the need for 'green' solvents in asymmetric catalysis. As such, the Ph-Garphos ligands were demethylated thereby introducing hydroxyl moieties unto the ligand scaffold. The facile tunability of the biaryl diphosphines led to the preparation of the (R)-(4,4',6,6'-tetrahydroxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (R-Ph-Garphos-OH), and (S)-(4,4',6,6'-tetrahydroxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (S-Ph-Garphos-OH) ligands. These were successfully characterized by CHN analysis, 1H, 13C, and 31P NMR spectroscopy, and polarimetry. The use of the Ph-Garphos and Ph-Garphos-OH ligands and their transition metal complexes in asymmetric hydrogenations will be reported.

The unique combination of soft phosphorus (P) and hard nitrogen (N) centres affords a variety of transition metal complexes as potential pre-catalysts for synthetically useful reactions. Herein three ligand systems will be reported; two bidentate ligands - (S)-8-(diphenyl-phosphino)-1,2,3,4-tetrahydronaphthalen-1-amine, (S)THNANH2, and (Rc)-1-((Sp)-2-diphenylphosphino) ferrocenylethylamine, (RcSp)PPFNH2 - and a tridentate (Rc)-1-((Sp)-2-diphenylphosphino) ferrocenylimino-pyridine, (RcSp)PPFNNH2 ligand; the latter prepared from the condensation of selected ferrocene aminophosphines with pyridine-2-carboxaldehyde. Suitable combinations of these aminophosphine ligands with ruthenium precursors have afforded highly efficient systems for the asymmetric hydrogenation and transfer hydrogenation of selected ketones in 2-propanol. The Ru-(S)THNANH2 precatalyst was the most efficient in the asymmetric hydrogenation of selected ketones with 100% conversions within 4 hours at a catalyst loading of 0.1 mol%. The Ru-(RcSp)PPFNNH2 precatalyst was the most efficient in the asymmetric transfer hydrogenation of the ketones with conversions as high as 98% with 0.1 mol% catalyst.

Their skeleton was previously found in quadranes produced by the terrestrial fungus Aspergillus terreus. Up to date, eleven suberosanes are described from which (-)-suberosanone and (-)-suberosenol A are reaching the picomolar cytotoxicity level on human solid tumors cell lines. Due to their impressive cytotoxic properties and their limited availability, we undertook an asymmetric synthesis of the most active members of this family in order to get insight into their absolute configurations and their biological properties. The challenge of their synthesis is the regio- and stereoselective elaboration of the compact bridged tricyclic skeleton with up to five all adjacent asymmetric centers, including a central quaternary carbon one. Our strategy is based on an aza-ene-synthesis key step which is regio-and stereo-controlled by the choice of a chiral amine enantiomer. it approach is concise and flexible, the enantiopur ABC tricyclic intermediate that have been synthesized being the common precursor of suberosanes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=suberosanes" title="suberosanes">suberosanes</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20synthesis" title=" asymmetric synthesis"> asymmetric synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=sesquiterpenes" title=" sesquiterpenes"> sesquiterpenes</a>, <a href="https://publications.waset.org/abstracts/search?q=quadranes" title=" quadranes"> quadranes</a> </p> <a href="https://publications.waset.org/abstracts/172533/asymmetric-synthesis-and-biological-study-of-suberosanes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172533.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">92</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">713</span> Numerical Buckling of Composite Cylindrical Shells under Axial Compression Using Asymmetric Meshing Technique (AMT)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zia%20R.%20Tahir">Zia R.

Mandal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the details of a numerical study of buckling and post buckling behaviour of laminated carbon fiber reinforced plastic (CFRP) thin-walled cylindrical shell under axial compression using asymmetric meshing technique (AMT) by ABAQUS. AMT is considered to be a new perturbation method to introduce disturbance without changing geometry, boundary conditions or loading conditions. Asymmetric meshing affects both predicted buckling load and buckling mode shapes. Cylindrical shell having lay-up orientation [0°/+45°/-45°/0°] with radius to thickness ratio (R/t) equal to 265 and length to radius ratio (L/R) equal to 1.5 is analysed numerically. A series of numerical simulations (experiments) are carried out with symmetric and asymmetric meshing to study the effect of asymmetric meshing on predicted buckling behaviour. Asymmetric meshing technique is employed in both axial direction and circumferential direction separately using two different methods, first by changing the shell element size and varying the total number elements, and second by varying the shell element size and keeping total number of elements constant. The results of linear analysis (Eigenvalue analysis) and non-linear analysis (Riks analysis) using symmetric meshing agree well with analytical results. The results of numerical analysis are presented in form of non-dimensional load factor, which is the ratio of buckling load using asymmetric meshing technique to buckling load using symmetric meshing technique. Using AMT, load factor has about 2% variation for linear eigenvalue analysis and about 2% variation for non-linear Riks analysis. The behaviour of load end-shortening curve for pre-buckling is same for both symmetric and asymmetric meshing but for asymmetric meshing curve behaviour in post-buckling becomes extraordinarily complex. The major conclusions are: different methods of AMT have small influence on predicted buckling load and significant influence on load displacement curve behaviour in post buckling; AMT in axial direction and AMT in circumferential direction have different influence on buckling load and load displacement curve in post-buckling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFRP%20composite%20cylindrical%20shell" title="CFRP composite cylindrical shell">CFRP composite cylindrical shell</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20meshing%20technique" title=" asymmetric meshing technique"> asymmetric meshing technique</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20buckling" title=" primary buckling"> primary buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20buckling" title=" secondary buckling"> secondary buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20eigenvalue%20analysis" title=" linear eigenvalue analysis"> linear eigenvalue analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20riks%20analysis" title=" non-linear riks analysis"> non-linear riks analysis</a> </p> <a href="https://publications.waset.org/abstracts/16401/numerical-buckling-of-composite-cylindrical-shells-under-axial-compression-using-asymmetric-meshing-technique-amt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16401.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">353</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">712</span> Modelling the Dynamics of Corporate Bonds Spreads with Asymmetric GARCH Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S%C3%A9lima%20Baccar">Sélima Baccar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ephraim%20Clark"> Ephraim Clark</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper can be considered as a new perspective to analyse credit spreads. A comprehensive empirical analysis of conditional variance of credit spreads indices is performed using various GARCH models. Based on a comparison between traditional and asymmetric GARCH models with alternative functional forms of the conditional density, we intend to identify what macroeconomic and financial factors have driven daily changes in the US Dollar credit spreads in the period from January 2011 through January 2013. The results provide a strong interdependence between credit spreads and the explanatory factors related to the conditions of interest rates, the state of the stock market, the bond market liquidity and the exchange risk. The empirical findings support the use of asymmetric GARCH models. The AGARCH and GJR models outperform the traditional GARCH in credit spreads modelling. We show, also, that the leptokurtic Student-t assumption is better than the Gaussian distribution and improves the quality of the estimates, whatever the rating or maturity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20bonds" title="corporate bonds">corporate bonds</a>, <a href="https://publications.waset.org/abstracts/search?q=default%20risk" title=" default risk"> default risk</a>, <a href="https://publications.waset.org/abstracts/search?q=credit%20spreads" title=" credit spreads"> credit spreads</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20garch%20models" title=" asymmetric garch models"> asymmetric garch models</a>, <a href="https://publications.waset.org/abstracts/search?q=student-t%20distribution" title=" student-t distribution"> student-t distribution</a> </p> <a href="https://publications.waset.org/abstracts/2699/modelling-the-dynamics-of-corporate-bonds-spreads-with-asymmetric-garch-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2699.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">474</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">711</span> Asymmetric Warfare: Exploratory Study of the Implicit Defense Strategy of the People's Republic of China in 2012-2016</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Victoria%20Alvarez%20Maga%C3%B1ini">María Victoria Alvarez Magañini</a>, <a href="https://publications.waset.org/abstracts/search?q=Lautaro%20Nahuel%20Rubbi"> Lautaro Nahuel Rubbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to different theories, the hegemonic war between the United States and the People's Republic of China seems to be imminent. However, nowadays, it is clear that China's conventional military capacity is inferior to that of the United States. Nevertheless, the conditions that in the past were considered to be an indicator of validity in asymmetrical warfare, at present, in a possible asymmetric war scenario, are no longer considered to be taken as such. The military capacity is not the only concept that represents the main indicator of victory. The organisation and the use of forces are also an essential part of it. The present paper aims to analyze the Chinese Defense Strategy in relation to the concept of asymmetric warfare in the face of a possible war with the United States. The starting point will be developed on the basis of application of the theory which corresponds to the concept aforementioned making focus on recent developments of the People’s Republic of China in the field of non-conventional defense.

Given several related tasks, the single-task learning methods trains each task separately and ignore the inner cross-relationship among tasks. However, multitask learning can capture the correlation information among tasks and achieve better performance by training all tasks simultaneously. In addition, the asymmetric squared loss function can better improve the generalization ability of the models on the most asymmetric distributed data. In this paper, we first make two assumptions on the relatedness among tasks and propose two multitask learning proximal support vector machine algorithms, named MTL-a-PSVM and EMTL-a-PSVM, respectively. MTL-a-PSVM seeks a trade-off between the maximum expectile distance for each task model and the closeness of each task model to the general model. As an extension of the MTL-a-PSVM, EMTL-a-PSVM can select appropriate kernel functions for shared information and private information. Besides, two corresponding special cases named MTL-PSVM and EMTLPSVM are proposed by analyzing the asymmetric squared loss function, which can be easily implemented by solving linear systems. Experimental analysis of three classification datasets demonstrates the effectiveness and superiority of our proposed multitask learning algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multitask%20learning" title="multitask learning">multitask learning</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20squared%20loss" title=" asymmetric squared loss"> asymmetric squared loss</a>, <a href="https://publications.waset.org/abstracts/search?q=EMTL-a-PSVM" title=" EMTL-a-PSVM"> EMTL-a-PSVM</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a> </p> <a href="https://publications.waset.org/abstracts/159613/the-asymmetric-proximal-support-vector-machine-based-on-multitask-learning-for-classification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159613.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">134</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">708</span> The Role of Multinational Enterprises' Investments in Emerging Country's Economic Development, Case of Georgia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Charaia">V. Charaia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> From the strategic point of view, not all Foreign Direct Investments (FDIs) are always positively benefiting the host economy, i.e. not all Multinational Enterprises (MNEs) are promoting local/host economies. FDI could have different impact on different sectors of the economy, based not only on annual investment amount, but MNE motivations and peculiarities of the host economy in particular. FDI analysis based only on its amount can lead to incorrect decisions, it is much more important to understand the essence of investment. Consequently, our research is oriented on MNE’s motivations, answering which sectors are most popular among international investors and why, what motivated them to invest into one or another business. Georgian economy for the last period of time is attracting more and more efficiency seeking investments, which could be translated as - concentrating production in a limited number of locations to supply various markets, while benefiting local economy with: new technologies, employment, exports diversification, increased income for the local economy and so on. Foreign investors and MNEs in particular are no longer and not so much interested in the resource seeking investments, which was the case for Georgia in the last decade of XX century. Despite the fact of huge progress for the Georgian economy, still there is a room for foreign investors to make a local market oriented investments. The local market is still rich in imported products, which should be replaced by local ones. And the last but not the least important issue is that approximately 30% of all FDIs in Georgia according to this research are “efficiency seeking” investments, which is an enormous progress and a hope for future Georgian success. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=investments" title="investments">investments</a>, <a href="https://publications.waset.org/abstracts/search?q=MNE" title=" MNE"> MNE</a>, <a href="https://publications.waset.org/abstracts/search?q=FDI%20motivations" title=" FDI motivations"> FDI motivations</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgian%20economy" title=" Georgian economy"> Georgian economy</a> </p> <a href="https://publications.waset.org/abstracts/66980/the-role-of-multinational-enterprises-investments-in-emerging-countrys-economic-development-case-of-georgia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66980.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">334</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">707</span> The Impact of the Interest Rates on Investments in the Context of Financial Crisis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Stawska">Joanna Stawska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this article is to examine the impact of interest rates on investments in Poland in the context of financial crisis. The paper also investigates the dependence of bank loans to enterprises on interbank market rates. The article studies the impact of interbank market rate on the level of investments in Poland. Besides, this article focuses on the research of the correlation between the level of corporate loans and the amount of investments in Poland in order to determine the indirect impact of central bank interest rates through the transmission mechanism of monetary policy on the real economy. To achieve the objective we have used econometric and statistical research methods like: econometric model and Pearson correlation coefficient. This analysis suggests that the central bank reference rate inversely proportionally affects the level of investments in Poland and this dependence is moderate. This is also important issue because it is related to preparing of Poland to accession to euro area. The research is important from both theoretical and empirical points of view. The formulated conclusions and recommendations determine the practical significance of the paper which may be used in the decision making process of monetary and economic authorities of the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=central%20bank" title="central bank">central bank</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20crisis" title=" financial crisis"> financial crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=interest%20rate" title=" interest rate"> interest rate</a>, <a href="https://publications.waset.org/abstracts/search?q=investments" title=" investments"> investments</a> </p> <a href="https://publications.waset.org/abstracts/22155/the-impact-of-the-interest-rates-on-investments-in-the-context-of-financial-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22155.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">442</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">706</span> Impact Assessment of Plum Research Investments in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Precious%20M.%20Tshabalala">Precious M.

Continued investments in agricultural research have led to the development of over 26 successful plum cultivars since 1980 at the Agricultural Research Council’s (ARC) Infruitec/Nietvoorbij in South Africa, and more continue to be developed to meet the specific needs of both producers and consumers. Yet very little is known about the returns on any of these research initiatives. The objective of the study was determine the economic impact of plum research investments at the ARC-the main plum breeding research organization in the country. The rate of return to plum research is estimated by estimating parameters in plum production and expressing research investment as an explanatory variable. The marginal rate of return is then determined to be 14.23 per cent. The rate of return to investment being this high is indicative of an under investment in plum research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agricultural%20research%20investments" title="Agricultural research investments">Agricultural research investments</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity%20and%20rate%20of%20return" title=" productivity and rate of return"> productivity and rate of return</a>, <a href="https://publications.waset.org/abstracts/search?q=plum" title=" plum "> plum </a> </p> <a href="https://publications.waset.org/abstracts/21543/impact-assessment-of-plum-research-investments-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21543.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">486</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">705</span> Plastic Strain Accumulation Due to Asymmetric Cyclic Loading of Zircaloy-2 at 400°C</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20S.%20Rajpurohit">R.

The problem is generally associated with nuclear fuel cladding materials used in nuclear power plants and pressurized pipelines. In the present investigation, asymmetric stress controlled fatigue tests were conducted with three different parameters namely, mean stress, stress amplitude and stress rate (keeping two parameters constant and varying third parameter) to see the plastic strain accumulation and its effect on fatigue life and deformation behavior of Zircaloy-2 at 400°C. The tests were conducted with variable mean stress (45-70 MPa), stress amplitude (95-120 MPa) and stress rate (30-750 MPa/s) and tested specimens were characterized using transmission and scanning electron microscopy. The experimental results show that with the increase in mean stress and stress amplitude, the ratcheting strain accumulation increases with reduction in fatigue life. However, increase in stress rate leads to improvement in fatigue life of the material due to small ratcheting strain accumulation. Fractographs showed a decrease in area fraction of fatigue failed region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20cyclic%20loading" title="asymmetric cyclic loading">asymmetric cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=ratcheting%20fatigue" title=" ratcheting fatigue"> ratcheting fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20stress" title=" mean stress"> mean stress</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20amplitude" title=" stress amplitude"> stress amplitude</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20rate" title=" stress rate"> stress rate</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20strain" title=" plastic strain"> plastic strain</a> </p> <a href="https://publications.waset.org/abstracts/70722/plastic-strain-accumulation-due-to-asymmetric-cyclic-loading-of-zircaloy-2-at-400c" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70722.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">275</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">704</span> Efficiency of Investments, Financed from EU Funds in Small and Medium Enterprises in Poland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jolanta%20Brodowska-Szewczuk">Jolanta Brodowska-Szewczuk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article includes the results and conclusions from empirical researches that had been done.

The main conclusions are that, companies with direct investments under this measure shall apply the modern methods of production. The consequence of this is to increase the quality of our products and services. Furthermore, both small and medium-sized enterprises have introduced new products and services. Investments were carried out, thus enabling better work organization in enterprises. Entrepreneurs would guarantee higher quality of service, which would result in better relationships with their customers, what is more, noting the rise in number of clients. More than half of the companies indicated that the investments contributed to the increase in market share. Same thing as for market reach and brand recognition of particular company.

Thereafter the stable operational flame regime is pursued as a key factor in optimizing the design of micro-combustors. The results show that with increasing velocities, four H2 flame regimes develop in the micro-combustor, namely: 1) periodic ignition-extinction regime, 2) steady symmetric regime, 3) pulsating asymmetric regime, and 4) steady asymmetric regime. The first regime that appears in 0.8 m/s inlet velocity is a periodic ignition-extinction regime which is characterized by counter flows and tulip-shape flames. For flow velocity above 0.2 m/s, the flame shifts downstream, and the combustion regime switches to a steady symmetric flame where temperature increases considerably due to the increased rate of incoming energy. Further elevation in flow velocity up to 1 m/s leads to the pulsating asymmetric flame formation, which is associated with pulses in various flame properties such as temperature and species concentration. Further elevation in flow velocity up to 1 m/s leads to the pulsating asymmetric flame formation, which is associated with pulses in various flame properties such as temperature and species concentration. Ultimately, when the inlet velocity reached 1.2 m/s, the last regime was observed, and a steady asymmetric regime appeared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermophotovoltaic%20generator" title="thermophotovoltaic generator">thermophotovoltaic generator</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20combustor" title=" micro combustor"> micro combustor</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20power%20generator" title=" micro power generator"> micro power generator</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20regimes" title=" combustion regimes"> combustion regimes</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20dynamic" title=" flame dynamic"> flame dynamic</a> </p> <a href="https://publications.waset.org/abstracts/165921/hydrogen-fueled-micro-thermophotovoltaic-power-generator-flame-regimes-and-flame-stability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165921.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">702</span> Impact of Foreign Direct Investment to the Economic Growth of Rwanda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munezero%20Vanessa">Munezero Vanessa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A country is considered developed when its socio-economic and development situation is stable. Foreign direct investment is thus considered to be one of the solutions to this stability especially when it is used in development sectors. The present study was meant to understand whether the foreign direct investment stimulates economic growth performance in Rwanda. The foreign direct investments and economic growth (GDP) has been the subject of much debate among economic development researchers, aid donors as well as recipients in general and Rwanda in particular. In spite of this, there are only few empirical studies that investigate the contributions of foreign direct investments to economic growth in Rwanda. This study explores the relationship between foreign direct investments and economic growth in Rwanda using data that spans from 2000 to 2019 and establishing through causal study if changes in one variable cause changes in the other. The results show that foreign direct investments significantly contribute to the current level of economic growth. The findings imply that Rwanda could enhance its economic growth by effectively and strategically strengthening foreign direct investment plans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foreign%20direct%20investment%20%28FDI%29" title="foreign direct investment (FDI)">foreign direct investment (FDI)</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=GDP%20gross%20domestic%20product%20%28GDP%29" title=" GDP gross domestic product (GDP)"> GDP gross domestic product (GDP)</a>, <a href="https://publications.waset.org/abstracts/search?q=inflation" title=" inflation"> inflation</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange%20rate" title=" exchange rate"> exchange rate</a> </p> <a href="https://publications.waset.org/abstracts/188725/impact-of-foreign-direct-investment-to-the-economic-growth-of-rwanda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188725.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">32</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">701</span> Paraplegic Dimensions of Asymmetric Warfare: A Strategic Analysis for Resilience Policy Plan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sehrish%20Qayyum">Sehrish Qayyum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this age of constant technology, asymmetrical warfare could not be won. Attuned psychometric study confirms that screaming sometimes is more productive than active retaliation against strong adversaries. Asymmetric warfare is a game of nerves and thoughts with least vigorous participation for large anticipated losses. It creates the condition of paraplegia with partial but permanent immobility, which effects the core warfare operations, being screams rather than active retaliation. When one’s own power is doubted, it gives power to one’s own doubt to ruin all planning either done with superlative cost-benefit analysis. Strategically calculated estimation of asymmetric warfare since the early WWI to WWII, WWII-to Cold War, and then to the current era in three chronological periods exposits that courage makes nations win the battle of warriors to battle of comrades. Asymmetric warfare has been most difficult to fight and survive due to unexpectedness and being lethal despite preparations. Thoughts before action may be the best-assumed strategy to mix Regional Security Complex Theory and OODA loop to develop the Paraplegic Resilience Policy Plan (PRPP) to win asymmetric warfare. PRPP may serve to control and halt the ongoing wave of terrorism, guerilla warfare, and insurgencies, etc. PRPP, along with a strategic work plan, is based on psychometric analysis to deal with any possible war condition and tactic to save millions of innocent lives such that lost in Christchurch New Zealand in 2019, November 2015 Paris attacks, and Berlin market attacks in 2016, etc. Getting tangled into self-imposed epistemic dilemmas results in regret that becomes the only option of performance. It is a descriptive psychometric analysis of war conditions with generic application of probability tests to find the best possible options and conditions to develop PRPP for any adverse condition possible so far. Innovation in technology begets innovation in planning and action-plan to serve as a rheostat approach to deal with asymmetric warfare. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20warfare" title="asymmetric warfare">asymmetric warfare</a>, <a href="https://publications.waset.org/abstracts/search?q=psychometric%20analysis" title=" psychometric analysis"> psychometric analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=PRPP" title=" PRPP"> PRPP</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a> </p> <a href="https://publications.waset.org/abstracts/122663/paraplegic-dimensions-of-asymmetric-warfare-a-strategic-analysis-for-resilience-policy-plan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122663.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">136</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">700</span> Mathematical Model of a Compound Gear Pump</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hsueh-Cheng%20Yang">Hsueh-Cheng Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The generation and design of compound involute spur gearings can be used in gear pump.

A numerical example that illustrates the developed compound rack cutter is represented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compound" title="compound">compound</a>, <a href="https://publications.waset.org/abstracts/search?q=involute%20teeth" title=" involute teeth"> involute teeth</a>, <a href="https://publications.waset.org/abstracts/search?q=gear%20pump" title=" gear pump"> gear pump</a>, <a href="https://publications.waset.org/abstracts/search?q=rack%20cutter" title=" rack cutter"> rack cutter</a> </p> <a href="https://publications.waset.org/abstracts/37181/mathematical-model-of-a-compound-gear-pump" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37181.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">374</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">699</span> Asymmetric Linkages Between Global Sustainable Index (Green Bond) and Cryptocurrency Markets with Portfolio Implications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faheem%20Ur%20Rehman">Faheem Ur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Khalil%20Khan"> Muhammad Khalil Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Miao%20Qing"> Miao Qing</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated the asymmetric links and portfolio strategies between green bonds and the markets of three different cryptocurrencies, i.e., green, Islamic, and conventional, using data from January 1, 2018, to April 8, 2022, and employing asymmetric TVP-VAR model to quantify risk spillovers in the network analysis. In addition, we use the minimum variance, minimum correlation, and minimum connectedness methodologies to assess the portfolio implications. The results of the asymmetric dynamic connectedness index (TCI) model show that by adopting cryptocurrencies for digital finance, risk spillovers are found to be reduced. The findings of net directional connectedness demonstrate that during the study period, green bonds consistently get return spillovers from all other network variables. Positive return spillovers are bigger in magnitude than negative ones. These results imply that the influence of the green bond market on the cryptocurrency markets is decreasing. Positive return spillovers generate higher connectedness values for (HG, BNB, and TRX) coins and persistent net recipients in the specific network. On the other hand, Cardano and ADA coins are persistent net transmitters in the system. XLM and MIOTA's responsibilities shift over time, and there is evidence of asymmetry when both positive and negative returns are considered. According to the pairwise portfolio weights, BNB vs. BTC has the largest portfolio weights in the system, followed by BNB vs. Ethereum, suggesting the best investment strategies in the network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20TVP-VAR" title="asymmetric TVP-VAR">asymmetric TVP-VAR</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20sustainable%20index" title=" global sustainable index"> global sustainable index</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptocurrency" title=" cryptocurrency"> cryptocurrency</a>, <a href="https://publications.waset.org/abstracts/search?q=portfolios" title=" portfolios"> portfolios</a> </p> <a href="https://publications.waset.org/abstracts/163872/asymmetric-linkages-between-global-sustainable-index-green-bond-and-cryptocurrency-markets-with-portfolio-implications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163872.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">78</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">698</span> Finite Elemental Simulation of the Combined Process of Asymmetric Rolling and Plastic Bending</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Pesin">A.

At these enterprises large parts of bodies of rotation are made on stamping units or bending and forming machines. In Nosov Magnitogorsk State Technical University in alliance with JSC "Magnitogorsk Metal and Steel Works" there was suggested and implemented the technology for producing such items based on a combination of asymmetric rolling processes and plastic bending under conditions of the plate mill. In this paper, based on finite elemental mathematical simulation in technology of a combined process of asymmetric rolling and bending plastic has been improved. It is shown that for the same curvature along the entire length of the metal sheet it is necessary to introduce additional asymmetry speed when rolling front end and tape trailer. Production of large bodies of rotation at mill 4500 JSC "Magnitogorsk Metal and Steel Works" showed good convergence of theoretical and experimental values of the curvature of the metal. Economic effect obtained more than 1.0 million dollars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20rolling"
