Economists have emphasized political elements and political scientists on political elements. This research reviews the political economy of poverty and corruption in Iran after the revolution. The findings of this research, based on AcemOgluand Robinson theory, show how the institutional structural dependence of Iran's economy to raw has led to the growth of its non-economic economic institutions and its consequence of the continuity of the release and looting economy and poverty and inequality in Iran's political economy Is. This research was carried out using descriptive-analytical and comparative methods. Many economists try to justify the conditions of the country based on war, sanctions; And the external factors, and ... knows. In this study, we tried to examine the roots of poverty and the looting economy of Iran by implementing Research AcemOgluand Robinson on the institutions and roots of poverty. Looking for a framework for understanding why countries, such as Iran, the reason for the difference in revenue in different countries, as well as the poor or wealth of countries, regardless of the non-effective and non-professional institutions, and why inefficient institutions in some countries, such as Iran, such as Iran It remains and does not have a voluntary political powers to change these institutions. Findings The research shows that institutions are broadly the main reason for the roots of the robust and looting economy (poverty and inequality) in Iran. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iran" title="Iran">Iran</a>, <a href="https://publications.waset.org/abstracts/search?q=plunderable%20%28Loot%29%20economy" title=" plunderable (Loot) economy"> plunderable (Loot) economy</a>, <a href="https://publications.waset.org/abstracts/search?q=raw%20shopping" title=" raw shopping"> raw shopping</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty%20and%20inequality" title=" poverty and inequality"> poverty and inequality</a>, <a href="https://publications.waset.org/abstracts/search?q=acem%20oglu%20and%20robinson" title=" acem oglu and robinson"> acem oglu and robinson</a>, <a href="https://publications.waset.org/abstracts/search?q=non-inclusive%20institutions" title=" non-inclusive institutions"> non-inclusive institutions</a> </p> <a href="https://publications.waset.org/abstracts/140888/the-roots-of-the-robust-and-looting-economy-poverty-and-inequality-in-iran-after-the-1979-revolution-from-the-perspective-of-acem-oglu-robinson-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140888.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">168</span> Comparative Study of Mechanical and Corrosion Behaviors on Heat Treated Steel Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20Robinson">Mario Robinson</a>, <a href="https://publications.waset.org/abstracts/search?q=Moe%20Rabea"> Moe Rabea</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research examines the effects of heat treatment processes on the mechanical properties and corrosion resistanceof1045 and 4140 Steel Alloysfor industrial applications.

The mechanical and corrosion resistance tests of the heat treated samples are carried out, and the results obtained are related to their SEMmorphologies analysis. The results show that the heat treatment processes have an effect on the tensile strength, impact, and a significant effect on the corrosion resistance of the alloy samples. With respect to the strain characteristics, significant improvement in the ductility of the samples is recorded in the full annealing and alloy tempered samples. Thus, for application requiring strength and ductility, such as in aerospace industries, this tempered heat treated alloy could be used.

However, travel SWB research in this area is still sporadic. Therefore, we are in need of a more systematic body of work that examines travel SWB considering various work occupations, working conditions, commuting variabilities, and other related variables, and develops updated qualitative and quantitative methods to inform the transportation design. In this Super Mario Guide, the author reflects on the related elements involved with travel SWB under four categories (having Super Mario as the protagonist): 1. the starting point including variables like living conditions; 2. the commuter including the commuter’s age, gender, occupation, and others; 3. the commuting including commuting environment, vehicles, commuting time, commuting vehicles flexibility and variability and others; 4. destination including the workplace conditions, the corporate culture on working flexibility, the employer supportiveness and others. In addition, with the rise of new vehicles such as auto-driving, this research can play a significant role to better understand travel SWB and to guide the design of more efficient travelling systems so as to improve worker performance and general SWB. The author also shares thoughts on promising areas for future research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transportation" title="transportation">transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=subjective%20well-being%20%28SWB%29" title=" subjective well-being (SWB)"> subjective well-being (SWB)</a>, <a href="https://publications.waset.org/abstracts/search?q=commuting" title=" commuting"> commuting</a>, <a href="https://publications.waset.org/abstracts/search?q=happiness" title=" happiness"> happiness</a> </p> <a href="https://publications.waset.org/abstracts/125483/super-mario-guide-an-updated-roadmap-on-research-with-travel-subjective-well-being" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125483.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">142</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">166</span> Chromium-Leaching Study of Cements in Various Environments </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Estokova">Adriana Estokova</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Palascakova"> Lenka Palascakova</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Kovalcikova"> Martina Kovalcikova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cement is a basic material used for building construction. Chromium as an indelible non-volatile trace element of raw materials occurs in cement clinker in the trivalent or hexavalent form. Hexavalent form of chromium is harmful and allergenic having very high water solubility and thus can easily come into contact with the human skin. The paper is aimed at analyzing the content of total chromium in Portland cements and leaching rate of hexavalent chromium in various leachants: Deionized water, Britton-Robinson buffer, used to simulate the natural environment, and hydrochloric acid (HCl). The concentration of total chromium in Portland cement samples was in a range from 173.2 to 218.5 mg/kg. The content of dissolved hexavalent chromium ranged 0.23-3.19, 2.0-5.78 and 8.88-16.25 mg/kg in deionized water, Britton-Robinson solution and hydrochloric acid, respectively. The calculated leachable fraction of Cr(VI) from cement samples was observed in the range 0.1--7.58 %. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environment" title="environment">environment</a>, <a href="https://publications.waset.org/abstracts/search?q=cement" title=" cement"> cement</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium" title=" chromium"> chromium</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a> </p> <a href="https://publications.waset.org/abstracts/45262/chromium-leaching-study-of-cements-in-various-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45262.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">277</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">165</span> Assessment of Carbon Dioxide Separation by Amine Solutions Using Electrolyte Non-Random Two-Liquid and Peng-Robinson Models: Carbon Dioxide Absorption Efficiency </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Esmaeili">Arash Esmaeili</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhibang%20Liu"> Zhibang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Xiang"> Yang Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimmy%20Yun"> Jimmy Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Shao"> Lei Shao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A high pressure carbon dioxide (CO<sub>2</sub>) absorption from a specific gas in a conventional column has been evaluated by the Aspen HYSYS simulator using a wide range of single absorbents and blended solutions to estimate the outlet CO<sub>2</sub> concentration, absorption efficiency and CO<sub>2</sub> loading to choose the most proper solution in terms of CO<sub>2 </sub>capture for environmental concerns.

The first method involves the Peng-Robinson (PR) Equation of State (EoS) with the conventional mixing rule of Van der Waals. The second approach involves the PR EOS together with the Wong Sandler (WS) mixing rule, coupled with the Uniquac Ge model. In order to model the bubble point pressures with this approach, the volume and area parameter for ethyl palmitate were estimated by the Hansen group contribution method. The last method involved the Peng-Robinson, combined with the Wong-Sandler Method, but using NRTL as the GE model. Results using the Van der Waals mixing rule clearly indicated that this method has the largest errors among all three methods, with errors in the range of 3.96–6.22 %. The Pr-Ws-Uniquac method exhibited small errors, with average absolute deviations between 0.95 to 1.97 percent. The Pr-Ws-Nrtl method led to the least errors where average absolute deviations ranged between 0.65-1.7%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bubble%20pressure" title="bubble pressure">bubble pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=Gibbs%20excess%20energy%20model" title=" Gibbs excess energy model"> Gibbs excess energy model</a>, <a href="https://publications.waset.org/abstracts/search?q=mixing%20rule" title=" mixing rule"> mixing rule</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20solubility" title=" CO2 solubility"> CO2 solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=ethyl%20palmitate" title=" ethyl palmitate"> ethyl palmitate</a> </p> <a href="https://publications.waset.org/abstracts/2308/bubble-point-pressures-of-co2ethyl-palmitate-by-a-cubic-equation-of-state-and-the-wong-sandler-mixing-rule" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2308.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">163</span> Impact of Slenderness Ratios on the Seismic Behavior of Reinforced Concrete Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Boj%C3%B3rquez">Juan Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=F.%20de%20Jes%C3%BAs%20Merino"> F. de Jesús Merino</a>, <a href="https://publications.waset.org/abstracts/search?q=Ed%C3%A9n%20Boj%C3%B3rquez"> Edén Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Llanez-Tizoc"> Mario Llanez-Tizoc</a>, <a href="https://publications.waset.org/abstracts/search?q=Federico%20Valenzuela-Beltr%C3%A1n"> Federico Valenzuela-Beltrán</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20R.%20Flores"> Mario R.

The blended amine solutions with the lowest PZ concentrations (5wt% and 10wt%) were considered and compared to reduce the cost of the process, among which the blended solution of 10wt%PZ+35wt%MDEA (methyldiethanolamine) was found as the most appropriate solution in terms of CO₂ content in the outlet gas, rich-CO₂ loading, and regeneration heat duty. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorption" title="absorption">absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=amine%20solutions" title=" amine solutions"> amine solutions</a>, <a href="https://publications.waset.org/abstracts/search?q=aspen%20HYSYS" title=" aspen HYSYS"> aspen HYSYS</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20loading" title=" CO₂ loading"> CO₂ loading</a>, <a href="https://publications.waset.org/abstracts/search?q=piperazine" title=" piperazine"> piperazine</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration%20heat%20duty" title=" regeneration heat duty"> regeneration heat duty</a> </p> <a href="https://publications.waset.org/abstracts/128137/simulation-and-assessment-of-carbon-dioxide-separation-by-piperazine-blended-solutions-using-e-nrtl-and-peng-robinson-models-study-of-regeneration-heat-duty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128137.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">188</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">161</span> Exergy Analysis of a Vapor Absorption Refrigeration System Using Carbon Dioxide as Refrigerant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samsher%20Gautam">Samsher Gautam</a>, <a href="https://publications.waset.org/abstracts/search?q=Apoorva%20Roy"> Apoorva Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhuvan%20Aggarwal"> Bhuvan Aggarwal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vapor absorption refrigeration systems can replace vapor compression systems in many applications as they can operate on a low-grade heat source and are environment-friendly. Widely used refrigerants such as CFCs and HFCs cause significant global warming. Natural refrigerants can be an alternative to them, among which carbon dioxide is promising for use in automotive air conditioning systems. Its inherent safety, ability to withstand high pressure and high heat transfer coefficient coupled with easy availability make it a likely choice for refrigerant. Various properties of the ionic liquid [bmim][PF₆], such as non-toxicity, stability over a wide temperature range and ability to dissolve gases like carbon dioxide, make it a suitable absorbent for a vapor absorption refrigeration system. In this paper, an absorption chiller consisting of a generator, condenser, evaporator and absorber was studied at an operating temperature of 70⁰C. A thermodynamic model was set up using the Peng-Robinson equations of state to predict the behavior of the refrigerant and absorbent pair at different points in the system. A MATLAB code was used to obtain the values of enthalpy and entropy at selected points in the system. The exergy destruction in each component and exergetic coefficient of performance (ECOP) of the system were calculated by performing an exergy analysis based on the second law of thermodynamics. Graphs were plotted between varying operating conditions and the ECOP obtained in each case. The effect of every component on the ECOP was examined. The exergetic coefficient of performance was found to be lesser than the coefficient of performance based on the first law of thermodynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%5Bbmim%5D%5BPF%E2%82%86%5D%20as%20absorbent" title="[bmim][PF₆] as absorbent">[bmim][PF₆] as absorbent</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20as%20refrigerant" title=" carbon dioxide as refrigerant"> carbon dioxide as refrigerant</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy%20analysis" title=" exergy analysis"> exergy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng-Robinson%20equations%20of%20state" title=" Peng-Robinson equations of state"> Peng-Robinson equations of state</a>, <a href="https://publications.waset.org/abstracts/search?q=vapor%20absorption%20refrigeration" title=" vapor absorption refrigeration"> vapor absorption refrigeration</a> </p> <a href="https://publications.waset.org/abstracts/73396/exergy-analysis-of-a-vapor-absorption-refrigeration-system-using-carbon-dioxide-as-refrigerant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73396.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">287</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">160</span> The Politics of Hope in Climate Change Fiction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naima%20Bilal">Naima Bilal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The contemporary Anthropocene novel, with all the atrocities, man-made and inflicted by Nature (and Supernature), differs from the Horror novel in one main characteristic, that being naively lingering to hope and the notion that all evils, days and people come to an end.

Ligamentous abnormalities can be congenital, or acquired through pregnancy, injury, or iatrogenic causes. Absence or laxity of these ligaments allows migration of the spleen into ectopic portions of the abdomen, which is also associated with an elongated vascular pedicle. Incidence of wandering spleen is reported at less than 0.25% with a female to male ratio of approximately 6:1. The most common complication of a wandering spleen is torsion around its vascular pedicle which can lead to thrombosis and infarction. Torsion of a wandering spleen is a rare but important cause of an acute abdomen. Imaging, and specifically CT or ultrasound, is crucial in the diagnosis. We present a case of a torsed wandering spleen which was treated with splenectomy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wandering%20Spleen" title="Wandering Spleen">Wandering Spleen</a>, <a href="https://publications.waset.org/abstracts/search?q=Torsion" title=" Torsion"> Torsion</a>, <a href="https://publications.waset.org/abstracts/search?q=Splenic%20Torsion" title=" Splenic Torsion"> Splenic Torsion</a>, <a href="https://publications.waset.org/abstracts/search?q=Spleen" title=" Spleen"> Spleen</a> </p> <a href="https://publications.waset.org/abstracts/162557/a-rare-case-report-of-wandering-spleen-torsion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162557.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">81</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">154</span> Reviving Sustainable Architecture in Non-Wester Culture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Asfour">Khaled Asfour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Going for LEED certification is the latest concern in Egyptian practice that only materialized during the last 4 years. Egyptian Consultant Group (ECG) together with Credit Agricole had the vision to design a headquarters (Cairo) that delivers a serious sustainable design. The bank is a strong advocator of “green banking” and supports renewable energy and energy saving projects. Their HQ in Cairo has passed all the hurdles to become the first platinum LEED certificate holder in Egypt. With this design Egyptian practice has finally re-engaged in a serious way with its long-standing traditions in sustainable architecture. Perhaps the closest to our memory is the medieval houses of Cairo. Few centuries later these qualities disappeared with the advent of Modern Movement that focused more on standard modernist image making than real localized quality of living environments. The first person to note this disappearance was Hassan Fathy half a century ago. Despite international applaud for his efforts he had no effect on prevailing local practice that continued senselessly adopting recycled modernist templates. The Egyptian society was not ready to accept any reference to historic architecture. Disciples of Hassan Fathy, few decades later sought, of tackling the lack of interest in green architecture in a different way. Mohamed Awad introduced in his design sustainable ideals inspired from traditional architecture rather than recycling directly historic forms and images. Despite success, this approach did not go far enough to influence the prevailing practice. Since year 2000 Egyptian economy was ebbing and flowing dramatically. This staggering fluctuation coupled by energy crisis has disillusioned architects and clients on the issue of modern image making. No more shining architecture under the sun with high running cost of fossil fuel. They sought of adopting contemporary green measures that offer pleasant living while saving on energy. A revival is on its way but is very slow and timid. The paper will present this problem of reviving sustainable architecture. How this process can be accelerated in order to give stronger impact on current practice will be addressed through the works of Mario Cucinella and Norman Foster. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LEED%20certification" title="LEED certification">LEED certification</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Fathy" title=" Hasan Fathy"> Hasan Fathy</a>, <a href="https://publications.waset.org/abstracts/search?q=Medieval%20architecture" title=" Medieval architecture"> Medieval architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Cucinella" title=" Mario Cucinella"> Mario Cucinella</a>, <a href="https://publications.waset.org/abstracts/search?q=Norman%20Foster" title=" Norman Foster"> Norman Foster</a> </p> <a href="https://publications.waset.org/abstracts/24924/reviving-sustainable-architecture-in-non-wester-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24924.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">491</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">153</span> Methodology for the Analysis of Energy Efficiency in Pneumatics Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20Lupaca">Mario Lupaca</a>, <a href="https://publications.waset.org/abstracts/search?q=Karol%20Munoz"> Karol Munoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20De%20Negri"> Victor De Negri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present article presents a methodology for the improvement of the energy efficiency in pneumatic systems through the restoring of air.

The methodology starts with the development of the GRAFCET of the system so that it can be decided whether to expand the cylinder in a conventional, efficient, or hybrid way.

As a result, They often show poor accuracy in the region near and above the critical point. In this study, the performance of the renowned Peng-Robinson (PR) and Patel-Teja (PT) EoS’s around the critical area has been examined against the P-v-T data of water. Both of them display large deviations at critical point. For instance, PR-EoS exhibits discrepancies as high as 47% for the specific volume, 28% for the enthalpy departure and 43% for the entropy departure at critical point. It is shown that incorporating P-v-T data of the supercritical region into the retuning of a cubic EoS can improve its performance above the critical point dramatically. Adopting a retuned acentric factor of 0.5491 instead of its genuine value of 0.344 for water in PR-EoS and a new F of 0.8854 instead of its original value of 0.6898 for water in PT-EoS reduces the discrepancies to about one third or less. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equation%20of%20state" title="equation of state">equation of state</a>, <a href="https://publications.waset.org/abstracts/search?q=EoS" title=" EoS"> EoS</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20water" title=" supercritical water"> supercritical water</a>, <a href="https://publications.waset.org/abstracts/search?q=SCW" title=" SCW"> SCW</a> </p> <a href="https://publications.waset.org/abstracts/2129/tuning-cubic-equations-of-state-for-supercritical-water-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2129.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">535</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">149</span> Interactive, Topic-Oriented Search Support by a Centroid-Based Text Categorisation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20Kubek">Mario Kubek</a>, <a href="https://publications.waset.org/abstracts/search?q=Herwig%20Unger"> Herwig Unger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Centroid terms are single words that semantically and topically characterise text documents and so may serve as their very compact representation in automatic text processing. In the present paper, centroids are used to measure the relevance of text documents with respect to a given search query. Thus, a new graphbased paradigm for searching texts in large corpora is proposed and evaluated against keyword-based methods. The first, promising experimental results demonstrate the usefulness of the centroid-based search procedure. It is shown that especially the routing of search queries in interactive and decentralised search systems can be greatly improved by applying this approach.

The selection of suitable partners has particular importance in the formation of horizontal cooperation. Up until now, literature mainly focused on general applicable methods for the identification of cooperation partners without a closer examination of the specific area where the cooperation takes place. Thus, specific criteria as a basis for the partner selection in the field of logistics cooperation are missing. To close this scientific gap, an explorative research approach is used to answer the open question of the article. To collect the needed criteria, a qualitative experiment with 20 participants from 16 companies was done. Within this workshop, general criteria, as well as sector-specific requirements, have been identified which were integrated in a partner selection model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=horizontal%20cooperation" title="horizontal cooperation">horizontal cooperation</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics%20cooperation%20partnering%20criteria" title=" logistics cooperation partnering criteria"> logistics cooperation partnering criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=partner%20selection" title=" partner selection"> partner selection</a> </p> <a href="https://publications.waset.org/abstracts/15860/partner-selection-for-horizontal-logistic-cooperation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15860.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">426</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">146</span> Process Modeling and Problem Solving: Connecting Two Worlds by BPMN</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gionata%20Carmignani">Gionata Carmignani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20G.%20C.%20A.%20Cimino"> Mario G.

In last year’s, the BP Model and Notation (BPMN) has become a de-facto standard for modeling processes. However, this standard does not incorporate explicitly the Problem-Solving (PS) knowledge in the Process Modeling (PM) results. Thus, such knowledge cannot be shared or reused. To narrow this gap is today a challenging research area. In this paper we present a framework able to capture the PS knowledge and to improve a workflow. This framework extends the BPMN specification by incorporating new general-purpose elements. A pilot scenario is also presented and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20process%20management" title="business process management">business process management</a>, <a href="https://publications.waset.org/abstracts/search?q=BPMN" title=" BPMN"> BPMN</a>, <a href="https://publications.waset.org/abstracts/search?q=problem%20solving" title=" problem solving"> problem solving</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20mapping" title=" process mapping"> process mapping</a> </p> <a href="https://publications.waset.org/abstracts/12641/process-modeling-and-problem-solving-connecting-two-worlds-by-bpmn" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12641.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">413</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">145</span> Coupling Concept of Two Parallel Research Codes for Two and Three Dimensional Fluid Structure Interaction Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Garelli">Luciano Garelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Schauer"> Marco Schauer</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20D%E2%80%99Elia"> Jorge D’Elia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20A.%20Storti"> Mario A.

Firstly, we studied the accuracy of the new model for three baseline distributions that lead to a Gumbel extreme distribution: Exponential, Normal and Gumbel. Secondly, we considered mixtures of Normal variables, to simulate practical situations when data do not adjust to pure distributions, because of perturbations (noise). <p
