However, these systems leave various levels of decisions to tourists to make by themselves. This incurs pressure on tourists and thereby bringing negative experience in their tour. This paper proposes a smart amusement park system to offer each tourist the GPS-based customized plan without tourists making decisions by themselves. The proposed system consists of the mobile app subsystem, the central subsystem, and the detecting/counting subsystem. The mobile app subsystem interacts with the central subsystem. The central subsystem performs the necessary computing and database management of the proposed system. The detecting/counting subsystem aims to detect and compute the number of visitors to an attraction. Experimental results show that the proposed system can not only work well, but also provide an innovative business operating model for owners of amusement parks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amusement%20park" title="amusement park">amusement park</a>, <a href="https://publications.waset.org/abstracts/search?q=location-based%20service" title=" location-based service"> location-based service</a>, <a href="https://publications.waset.org/abstracts/search?q=LBS" title=" LBS"> LBS</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20app" title=" mobile app"> mobile app</a>, <a href="https://publications.waset.org/abstracts/search?q=tourist%20service" title=" tourist service"> tourist service</a> </p> <a href="https://publications.waset.org/abstracts/32047/sap-a-smart-amusement-park-system-for-tourist-services" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32047.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">512</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">1111</span> Performance Assessment of Three Unit Redundant System with Environmental and Human Failure Using Copula Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20V.%20Singh">V.

The subsystem-1 has three identical units in parallel configuration and operating under 2-out-of-3: G policy and connected to subsystem-2 in series configuration. Each subsystem has different types of failure and repair rates. An important cause for failure of system is unsuitability of the environmental conditions, like overheating, weather conditions, heavy rainfall, storm etc. The environmental failure is taken into account in the proposed repairable system. Supplementary variable technique is used to study of system and some traditional measures such as; availability, reliability, MTTF and profit function are obtained for different values of parameters.

These SSD potentials have drawn great attention from IT enterprises that seek for better I/O performance. However, high SSD cost per capacity makes it less desirable to construct a large-scale storage subsystem solely composed of SSD devices. An alternative is to build a hybrid storage subsystem where both HDD and SSD devices are incorporated in an economic manner, while employing the strengths of both devices. This paper presents a hybrid file system, called hybridFS, that attempts to utilize the advantages of HDD and SSD devices, to provide a single, virtual address space by integrating both devices. HybridFS not only proposes an efficient implementation for the file management in the hybrid storage subsystem but also suggests an experimental framework for making use of the excellent features of existing file systems. Several performance evaluations were conducted to verify the effectiveness and suitability of hybridFS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20file%20mapping" title="hybrid file mapping">hybrid file mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20layout" title=" data layout"> data layout</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20device%20integration" title=" hybrid device integration"> hybrid device integration</a>, <a href="https://publications.waset.org/abstracts/search?q=extent%20allocation" title=" extent allocation"> extent allocation</a> </p> <a href="https://publications.waset.org/abstracts/16492/utilizing-hybrid-file-mapping-for-high-performance-io" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16492.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">506</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">1104</span> Stochastic Analysis of Linux Operating System through Copula Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vijay%20Vir%20Singh">Vijay Vir Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is focused studying the Linux operating system connected in a LAN (local area network).

The various measures of reliability for example, availability of system, reliability of system, MTTF, profit function for different parametric values have been discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=star%20topology" title="star topology">star topology</a>, <a href="https://publications.waset.org/abstracts/search?q=bus%20topology" title=" bus topology"> bus topology</a>, <a href="https://publications.waset.org/abstracts/search?q=blocking" title=" blocking"> blocking</a>, <a href="https://publications.waset.org/abstracts/search?q=hacking" title=" hacking"> hacking</a>, <a href="https://publications.waset.org/abstracts/search?q=Linux%20operating%20system" title=" Linux operating system"> Linux operating system</a>, <a href="https://publications.waset.org/abstracts/search?q=Gumbel-Hougaard%20family%20copula" title=" Gumbel-Hougaard family copula"> Gumbel-Hougaard family copula</a>, <a href="https://publications.waset.org/abstracts/search?q=supplementary%20variable" title=" supplementary variable"> supplementary variable</a> </p> <a href="https://publications.waset.org/abstracts/48060/stochastic-analysis-of-linux-operating-system-through-copula-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48060.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">370</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">1103</span> Numerical and Experimental Investigation of a Mechanical System with a Pendulum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrzej%20Mitura">Andrzej Mitura</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Kecik"> Krzysztof Kecik</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Augustyniak"> Michal Augustyniak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a numerical and experimental research of a nonlinear two degrees of freedom system. The tested system consists of a mechanical oscillator (the primary subsystem) with the attached pendulum (the secondary subsystem). The oscillator is suspended on a linear (or nonlinear) coil spring and a nonlinear magnetorheorogical damper and it is excited kinematically. Added pendulum can be used to reduce vibration of a primary subsystem or to energy harvesting. The numerical and experimental investigations showed that the pendulum can perform several types of motion, for example: chaotic motion, constant position in lower or upper (stable inverted pendulum), rotation, symmetrical or asymmetrical swinging vibrations. The main objective of this study is to determine an influence of system parameters for increasing the zone when the pendulum rotates. As a final effect a semi-active control method to change the pendulum solution on the rotation is proposed. To the implementation of this method the magnetorheorogical damper is applied. Continuous rotation of the pendulum is desirable for recovery of energy.

The role of the optimization and decision subsystem is to provide the user with better and optimal scenarios that will best fulfill any constrains, goals or requirements posed. The complexity of the problem and the large number of parameters and objectives involved led to the adoption of an evolutionary method (Genetic Algorithms).

It begins by outlining, theoretically, an a priori model of its general cognitive mechanisms. The obtained theoretical framework represents the designing activity as a complex system composed of three interrelated subsystems of cognitive actions: a subsystem of meaning production, one of morphology production and finally a subsystem of navigation between the two formers. A protocol analysis that uses statistical and informational tools is then used to measure the validity of the built schema. The model thus achieved shows that the designer begins by conceiving abstract meanings, which he then translates into shapes. That’s why we call it a semio-morphic model of the designing activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=designing%20actions" title="designing actions">designing actions</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20of%20the%20design%20process" title=" model of the design process"> model of the design process</a>, <a href="https://publications.waset.org/abstracts/search?q=morphosis" title=" morphosis"> morphosis</a>, <a href="https://publications.waset.org/abstracts/search?q=protocol%20analysis" title=" protocol analysis"> protocol analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=semiosis" title=" semiosis"> semiosis</a> </p> <a href="https://publications.waset.org/abstracts/89862/a-cognitive-schema-of-architectural-designing-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89862.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">172</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">1100</span> Modeling and Temperature Control of Water-cooled PEMFC System Using Intelligent Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Jun-Hong">Chen Jun-Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=He%20Pu"> He Pu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Wen-Quan"> Tao Wen-Quan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Proton exchange membrane fuel cell (PEMFC) is the most promising future energy source owing to its low operating temperature, high energy efficiency, high power density, and environmental friendliness. In this paper, a comprehensive PEMFC system control-oriented model is developed in the Matlab/Simulink environment, which includes the hydrogen supply subsystem, air supply subsystem, and thermal management subsystem. Besides, Improved Artificial Bee Colony (IABC) is used in the parameter identification of PEMFC semi-empirical equations, making the maximum relative error between simulation data and the experimental data less than 0.4%. Operation temperature is essential for PEMFC, both high and low temperatures are disadvantageous. In the thermal management subsystem, water pump and fan are both controlled with the PID controller to maintain the appreciate operation temperature of PEMFC for the requirements of safe and efficient operation. To improve the control effect further, fuzzy control is introduced to optimize the PID controller of the pump, and the Radial Basis Function (RBF) neural network is introduced to optimize the PID controller of the fan. The results demonstrate that Fuzzy-PID and RBF-PID can achieve a better control effect with 22.66% decrease in Integral Absolute Error Criterion (IAE) of T_st (Temperature of PEMFC) and 77.56% decrease in IAE of T_in (Temperature of inlet cooling water) compared with traditional PID. In the end, a novel thermal management structure is proposed, which uses the cooling air passing through the main radiator to continue cooling the secondary radiator. In this thermal management structure, the parasitic power dissipation can be reduced by 69.94%, and the control effect can be improved with a 52.88% decrease in IAE of T_in under the same controller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PEMFC%20system" title="PEMFC system">PEMFC system</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20identification" title=" parameter identification"> parameter identification</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20control" title=" temperature control"> temperature control</a>, <a href="https://publications.waset.org/abstracts/search?q=Fuzzy-PID" title=" Fuzzy-PID"> Fuzzy-PID</a>, <a href="https://publications.waset.org/abstracts/search?q=RBF-PID" title=" RBF-PID"> RBF-PID</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20power" title=" parasitic power"> parasitic power</a> </p> <a href="https://publications.waset.org/abstracts/183259/modeling-and-temperature-control-of-water-cooled-pemfc-system-using-intelligent-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183259.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">85</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">1099</span> Fault Detection and Isolation in Attitude Control Subsystem of Spacecraft Formation Flying Using Extended Kalman Filters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Ghasemi">S.

The challenging and addictive nature of this game has made it a ubiquitous game. Most magazines, newspapers, puzzle books, etc. publish lots of Sudoku puzzles every day. These puzzles often come in different levels of difficulty so that all people, from beginner to expert, can play the game and enjoy it. Generating puzzles with different levels of difficulty is a major concern of Sudoku designers. There are several works in the literature which propose ways of generating puzzles having a desirable level of difficulty. In this paper, we propose a method based on constraint satisfaction problems to evaluate the difficulty of the Sudoku puzzles. Then, we propose a hill climbing method to generate puzzles with different levels of difficulty. Whereas other methods are usually capable of generating puzzles with only few number of difficulty levels, our method can be used to generate puzzles with arbitrary number of different difficulty levels. We test our method by generating puzzles with different levels of difficulty and having a group of 15 people solve all the puzzles and recording the time they spend for each puzzle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constraint%20satisfaction%20problem" title="constraint satisfaction problem">constraint satisfaction problem</a>, <a href="https://publications.waset.org/abstracts/search?q=generating%20Sudoku%20puzzles" title=" generating Sudoku puzzles"> generating Sudoku puzzles</a>, <a href="https://publications.waset.org/abstracts/search?q=hill%20climbing" title=" hill climbing"> hill climbing</a> </p> <a href="https://publications.waset.org/abstracts/8625/rating-and-generating-sudoku-puzzles-based-on-constraint-satisfaction-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8625.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">402</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">1095</span> The LIP’s Electric Propulsion Development for Chinese Spacecraft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Tianping">Zhang Tianping</a>, <a href="https://publications.waset.org/abstracts/search?q=Jia%20Yanhui"> Jia Yanhui</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Juan"> Li Juan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Le"> Yang Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Hao"> Yang Hao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Wei"> Yang Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Xiaojing"> Sun Xiaojing</a>, <a href="https://publications.waset.org/abstracts/search?q=Shi%20Kai"> Shi Kai</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Xingda"> Li Xingda</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Yunkui"> Sun Yunkui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lanzhou Institute of Physics (LIP) is the major supplier of electric propulsion subsystems for Chinese satellite platforms.

The Kolb Learning Styles Inventory and a set of developed questionnaires were used in this research. The results showed that the most dominant learning style is among technical students is Doer. A total of 319 (85.1%) technical students faced difficulties in solving individual assignments. Most of the problem faced by technical students is the difficulty of generating ideas for solving individual assignments. There was no significant difference in difficulties of generating ideas according to students’ learning styles.

Consequently, they are classified as cash-generating and non-cash-generating assets. IPSAS 21 - Impairment of non-cash-generating assets, and IPSAS 26 - Impairment of cash-generating assets, have been designed considering this specificity.  When measuring impairment of assets, it is important to select the relevant methods. For measurement of the impaired Non-Cash-Generating Assets, IPSAS 21 recommends three methods: Depreciated Replacement Cost Approach, Restoration Cost Approach, and  Service Units Approach. Impairment of Value in Use of Cash-Generating Assets (according to IPSAS 26) is measured by discounted value of the money sources to be received in future. Value in use of the cash-generating asserts (as per IPSAS 26) is measured by the discounted value of the money sources to be received in the future. The article provides classification of the assets in the public sector  as non-cash-generating assets and cash-generating assets and, deals also with the factors which should be considered when evaluating  impairment of assets. An essence of impairment of the non-financial assets and the methods of measurement thereof evaluation are formulated according to IPSAS 21 and IPSAS 26. The main emphasis is put on different methods of measurement of the value in use of the impaired Cash-Generating Assets and Non-Cash-Generation Assets and the methods of their selection. The traditional and the expected cash flow approaches for calculation of the discounted value are reviewed. The article also discusses the issues of recognition of impairment loss and its reflection in the financial reporting. The article concludes that despite a functional purpose of the impaired asset, whichever method is used for measuring the asset, presentation of realistic information regarding the value of the assets should be ensured in the financial reporting. In the theoretical development of the issue, the methods of scientific abstraction, analysis and synthesis were used. The research was carried out with a systemic approach. The research process uses international standards of accounting, theoretical researches and publications of Georgian and foreign scientists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cash-generating%20%20assets" title="cash-generating assets">cash-generating assets</a>, <a href="https://publications.waset.org/abstracts/search?q=non-cash-generating%20%20assets" title=" non-cash-generating assets"> non-cash-generating assets</a>, <a href="https://publications.waset.org/abstracts/search?q=recoverable%20%28usable%20restorative%29%20value" title=" recoverable (usable restorative) value"> recoverable (usable restorative) value</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20of%20use" title=" value of use"> value of use</a> </p> <a href="https://publications.waset.org/abstracts/101640/some-issues-of-measurement-of-impairment-of-non-financial-assets-in-the-public-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101640.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1092</span> Short-Range and Long-Range Ferrimagnetic Order in Fe(Te₁.₅Se₀.₅)O₅Cl</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20S.%20Kozlyakova">E.

The efforts to grow its selenite sibling resulted in mixed halide compound, Fe(Te₁.₅Se₀.₅)O₅Cl, which was found crystallizing in a new structural type and possessing properties drastically different from those of a parent system. Hereby we report the studies of magnetization M and specific heat Cₚ, combined with Raman spectroscopy and density functional theory calculations in Fe(Te₁.₅Se₀.₅)O₅Cl. Its magnetic subsystem features weakly coupled Fe³⁺ - Fe³⁺ dimers showing the regime of short-range correlations at TM ~ 70 K and long-range order at TN = 22 K. In a magnetically ordered state, sizable spin-orbital interactions lead to a small canting of Fe³⁺ moments. The density functional theory calculations of leading exchange interactions were found in agreement with measurements of thermodynamic properties and Raman spectroscopy. Besides, because of the relatively large magnetic moment of the Fe³⁺ ion, we found that magnetic dipole-dipole interactions contribute significantly to experimentally observed orientation of magnetization easy axis in ac-plane. As a conclusion, we suggest a model of magnetic subsystem in magnetically ordered state of Fe(Te₁.₅Se₀.₅)O₅Cl based on a model of interacting dimers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dipole-dipole%20interactions" title="dipole-dipole interactions">dipole-dipole interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20dimensional%20magnetism" title=" low dimensional magnetism"> low dimensional magnetism</a>, <a href="https://publications.waset.org/abstracts/search?q=selenite" title=" selenite"> selenite</a>, <a href="https://publications.waset.org/abstracts/search?q=spin%20canting" title=" spin canting"> spin canting</a> </p> <a href="https://publications.waset.org/abstracts/130861/short-range-and-long-range-ferrimagnetic-order-in-fete15se05o5cl" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130861.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">165</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">1091</span> Bernstein Type Polynomials for Solving Differential Equations and Their Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yilmaz%20Simsek">Yilmaz Simsek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we study the Bernstein-type basis functions with their generating functions.

To address this shortfall, recent research in integration readiness level (IRL) combines with technology readiness level (TRL) to form a system readiness level (SRL). SRL can be enriched with more robust quantitative methods to provide the program manager a useful tool prior to committing to major weapons acquisition programs. This research harnesses previous mathematical models based on graph theory, Petri nets, and tropical algebra and proposes a modification of the desirable SRL mathematical properties such that a tightly integrated (multitude of interfaces) subsystem can display a lower SRL than an inherently less coupled subsystem. The synthesis of these methods informs an improved decision tool for the program manager to commit to expensive technology development. This research ties the separately developed manufacturing readiness level (MRL) into the network representation of the system and addresses shortfalls in previous frameworks, including the lack of integration weighting and the over-importance of a single extremely immature component. Tropical algebra (based on the minimum of a set of TRLs or IRLs) allows one low IRL or TRL value to diminish the SRL of the entire system, which may not be reflective of actuality if that component is not critical or tightly coupled. Integration connections can be weighted according to importance and readiness levels are modified to be a cardinal scale (based on an analytic hierarchy process). Integration arcs’ importance are dependent on the connected nodes and the additional integrations arcs connected to those nodes. Lack of integration is not represented by zero, but by a perfect integration maturity value. Naturally, the importance (or weight) of such an arc would be zero. To further explore the impact of grouping subsystems, a multi-objective genetic algorithm is then used to find various clusters or communities that can be optimized for the most representative subsystem SRL. This novel calculation is then benchmarked through simulation and using past defense acquisition program data, focusing on the newly introduced Middle Tier of Acquisition (rapidly field prototypes). The model remains a relatively simple, accessible tool, but at higher fidelity and validated with past data for the program manager to decide major defense acquisition program milestones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=readiness" title="readiness">readiness</a>, <a href="https://publications.waset.org/abstracts/search?q=maturity" title=" maturity"> maturity</a>, <a href="https://publications.waset.org/abstracts/search?q=system" title=" system"> system</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a> </p> <a href="https://publications.waset.org/abstracts/171430/cluster-based-exploration-of-system-readiness-levels-mathematical-properties-of-interfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171430.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">1086</span> Central Solar Tower Model </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmo%20Thiago%20Lins%20C%C3%B6uras%20Ford">Elmo Thiago Lins Cöuras Ford</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Alessandra%20Carvalho%20do%20Vale"> Valentina Alessandra Carvalho do Vale</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is presented a model of two subsystems of Central Solar Tower to produce steam in applications to help in energy consumption.

Having reliable systems to facilitate the process of modeling and prediction of traffic conditions would not only reduce the environmental pollution, but will also save people time and money. Social networks play big role of people’s lives nowadays providing them means of communicating and sharing thoughts and ideas, that way generating huge knowledge bases by crowdsourcing. In addition to that, crowdsourcing as a concept provides mechanisms for fast and relatively reliable data generation and also many services are being used on regular basis because they are mainly powered by the public as main content providers. In this paper we present the Social-NETS-Traffic-Control System (SNTCS) that should serve as a facilitator in the process of modeling and prediction of traffic congestions. The main contribution of our system is to integrate data from social networks as Twitter and also implements a custom created crowdsourcing subsystem with which users report traffic conditions using an android application. Our first experience of the usage of the system confirms that the integrated approach allows easy extension of the system with other social networks and represents a very useful tool for traffic control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traffic" title="traffic">traffic</a>, <a href="https://publications.waset.org/abstracts/search?q=congestion%20reduction" title=" congestion reduction"> congestion reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=crowdsource" title=" crowdsource"> crowdsource</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networks" title=" social networks"> social networks</a>, <a href="https://publications.waset.org/abstracts/search?q=twitter" title=" twitter"> twitter</a>, <a href="https://publications.waset.org/abstracts/search?q=android" title=" android"> android</a> </p> <a href="https://publications.waset.org/abstracts/25742/traffic-congestions-modeling-and-predictions-by-social-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25742.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">481</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">1084</span> An Axiomatic Model for Development of the Allocated Architecture in Systems Engineering Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Sharahi">Amir Sharahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Tehrani"> Reza Tehrani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mollajan"> Ali Mollajan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The final step to complete the “Analytical Systems Engineering Process” is the “Allocated Architecture” in which all Functional Requirements (FRs) of an engineering system must be allocated into their corresponding Physical Components (PCs). At this step, any design for developing the system’s allocated architecture in which no clear pattern of assigning the exclusive “responsibility” of each PC for fulfilling the allocated FR(s) can be found is considered a poor design that may cause difficulties in determining the specific PC(s) which has (have) failed to satisfy a given FR successfully. The present study utilizes the Axiomatic Design method principles to mathematically address this problem and establishes an “Axiomatic Model” as a solution for reaching good alternatives for developing the allocated architecture. This study proposes a “loss Function”, as a quantitative criterion to monetarily compare non-ideal designs for developing the allocated architecture and choose the one which imposes relatively lower cost to the system’s stakeholders. For the case-study, we use the existing design of U. S. electricity marketing subsystem, based on data provided by the U.S. Energy Information Administration (EIA). The result for 2012 shows the symptoms of a poor design and ineffectiveness due to coupling among the FRs of this subsystem. <p class="card-text"><strong>Keywords:</strong> <a
