Further, there is no available literature that discusses how a place can be manipulated via design and/or policy to allow people to feel/get attached to it, an aspect that seems to be the need of the hour in a world where a substantial population is living in shelter homes as war/climate/social refugees. Consequently, this paper draws from studies on place, affordance and attachment to conceptualize an objectively measurable entity in place attachment affordance by asking ‘whether and to what degree a place allows one to form attachment bonds with it’ rather than the generally asked ‘whether and to what degree one is/feels attached to a place’. Towards this, the place attachment affordance scale (PAAS) has been developed to not only quantitatively measure place attachment affordance but also act as a point of entry into a more in-depth analysis of both place policy and place properties. To illustrate the validity of the scale, the study uses PAAS to compare shelter homes for women in crisis with the homes they once lived in to glean the degree to which both places afford the formation of place attachment bonds to the residents. PAAS has also been used to compare shelter homes as places of short-/long-term residence for the residents and as places of work for the staff. Based on the results, it is suggested that place attachment and built environment researchers employ the PAAS as an objective measurement tool to better understand not only the presence or absence of attachment bonds with place but also the attributes of place that encourage or discourage the same. The study also briefly discusses the universality of the PAAS, although further fieldwork might be required to substantiate the same. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=place%20attachment" title="place attachment">place attachment</a>, <a href="https://publications.waset.org/abstracts/search?q=affordance" title=" affordance"> affordance</a>, <a href="https://publications.waset.org/abstracts/search?q=shelter%20homes" title=" shelter homes"> shelter homes</a>, <a href="https://publications.waset.org/abstracts/search?q=home" title=" home"> home</a>, <a href="https://publications.waset.org/abstracts/search?q=scale" title=" scale"> scale</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20psychology" title=" environmental psychology"> environmental psychology</a> </p> <a href="https://publications.waset.org/abstracts/188893/conceptualizing-place-attachment-affordance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188893.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">29</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">22</span> Deploying a Platform as a Service Cloud Solution to Support Student Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiangping%20Wang">Jiangping Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This presentation describes the design and implementation of PaaS (platform as a service) cloud-based labs that are used in database-related courses to teach students practical skills. Traditionally, all labs are implemented in a desktop-based environment where students have to install heavy client software to access database servers. In order to release students from that burden, we have successfully deployed the cloud-based solution to support database-related courses, from which students and teachers can practice and learn database topics in various database courses via cloud access. With its development environment, execution runtime, web server, database server, and collaboration capability, it offers a shared pool of configurable computing resources and comprehensive environment that supports students’ needs without the complexity of maintaining the infrastructure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PaaS" title="PaaS">PaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=database%20environment" title=" database environment"> database environment</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20server" title=" web server"> web server</a> </p> <a href="https://publications.waset.org/abstracts/84830/deploying-a-platform-as-a-service-cloud-solution-to-support-student-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84830.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">268</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">21</span> A Rare Case of Popliteal Artery Aneurysm Presenting with Foot Drop</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Yahng">John Yahng</a>, <a href="https://publications.waset.org/abstracts/search?q=Riteesh%20Bookun"> Riteesh Bookun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Popliteal artery aneurysms (PAAs) are the most common arterial aneurysm of the periphery.

The proposed architecture consists of establishing user configurable ‘sticky’ policies on the Graphical User Interface (GUI) data-bound components during the application development phase to specify the details of privacy enforcement on the contents of these components. Various privacy classification classes on the data components are formally defined to give the user full control on the degree and scope of privacy enforcement including the type of execution containers to process the data in the Cloud. This not only enhances the privacy-awareness of the developed Cloud services, but also results in major savings in performance and energy efficiency due to the fact that the privacy mechanisms are solely applied on sensitive data units and not on all the user content. The proposed design is implemented in a real PaaS cloud computing environment on the Microsoft Azure platform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=privacy%20enforcement" title="privacy enforcement">privacy enforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=platform-as-a-service%20privacy%20awareness" title=" platform-as-a-service privacy awareness"> platform-as-a-service privacy awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing%20privacy" title=" cloud computing privacy"> cloud computing privacy</a> </p> <a href="https://publications.waset.org/abstracts/131754/platform-as-a-service-sticky-policies-for-privacy-classification-in-the-cloud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131754.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">226</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> An Application Framework for Integrating Wireless Sensor and Actuator Networks for Precision Farmingas Web of Things to Cloud Interface Using PaaS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumaya%20Ismail">Sumaya Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Aijaz%20Ahmad%20Reshi"> Aijaz Ahmad Reshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advances in sensor and embedded technologies have led to rapid developments in Wireless Sensor Networks (WSNs). Presently researchers focus on the integration of WSNs to the Internet for their pervasive availability to access these network resources as the interoperable subsystems. The recent computing technologies like cloud computing has made resource sharing as a converged infrastructure with required service interfaces for the shared resources over the Internet. This paper presents application architecture for wireless Sensor and Actuator Networks (WSANS) following web of things, which allows easy integration of each node to the Internet in order to provide them with web accessibility. The architecture enables the sensors and actuator nodes accessed and controlled using cloud interface on WWW. The application architecture was implemented using existing web and its emerging technologies. In particular, the Representational State Transfer protocol (REST) was extended for the specific requirements of the application. The Cloud computing environment has been used as a development platform for the application to assess the possibility of integrating the WSAN nodes to Cloud services. The mushroom farm environment monitoring and control using WSANs has been taken as a research use case. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=WSAN" title="WSAN">WSAN</a>, <a href="https://publications.waset.org/abstracts/search?q=REST" title=" REST"> REST</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20of%20things" title=" web of things"> web of things</a>, <a href="https://publications.waset.org/abstracts/search?q=ZigBee" title=" ZigBee"> ZigBee</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20interface" title=" cloud interface"> cloud interface</a>, <a href="https://publications.waset.org/abstracts/search?q=PaaS" title=" PaaS"> PaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20gateway" title=" sensor gateway"> sensor gateway</a> </p> <a href="https://publications.waset.org/abstracts/151111/an-application-framework-for-integrating-wireless-sensor-and-actuator-networks-for-precision-farmingas-web-of-things-to-cloud-interface-using-paas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151111.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">104</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">17</span> Efficient Storage in Cloud Computing by Using Index Replica </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Singh%20Deora">Bharat Singh Deora</a>, <a href="https://publications.waset.org/abstracts/search?q=Sushma%20Satpute"> Sushma Satpute</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cloud computing is based on resource sharing.

Organizations are now looking toward virtualization in order to minimize their computing cost. Cloud Computing has also introduced itself by the means of reducing computing cost. It offers different approach to make computing better by improving utilization and reducing infrastructure and administrative costs. Cloud Computing is basically the amalgamation of Utility Computing and SaaS (Software as a Service). Cloud Computing is quite new to organizations as it is still at its deploying stage. Due to this reason, organizations are not confident whether to adopt it or not. This thesis investigates the problem for organization concerning the security and cost issues. Benefits and drawbacks are being highlighted which organizations can have or suffer in order to adopt Cloud Computing. In Conclusion, Cloud Computing is a better option available for small and medium organizations with a comparison to large companies both in terms of data security and cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title="cloud computing">cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=cost" title=" cost"> cost</a>, <a href="https://publications.waset.org/abstracts/search?q=elasticity" title=" elasticity"> elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=PaaS" title=" PaaS"> PaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=IaaS" title=" IaaS"> IaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=SaaS" title=" SaaS"> SaaS</a> </p> <a href="https://publications.waset.org/abstracts/46177/effect-of-cloud-computing-on-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46177.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">340</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">13</span> SciPaaS: a Scientific Execution Platform for the Cloud</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wesley%20H.%20Brewer">Wesley H.

It provides all the necessary infrastructure for running typical IXP (Input-eXecute-Plot) style apps, including: a web interface, post-processing and plotting capabilities, job scheduling, real-time monitoring of running jobs, and even a file/case manager. In this paper, first the system architecture is described and then is demonstrated for a two scientific applications: (1) a simple finite-difference solver of the inviscid Burger’s equation, and (2) Mendel’s Accountant—a forward-time population genetics simulation model. The implications of the prototype are discussed in terms of ease-of-use and deployment options, especially in cloud environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=web-based%20simulation" title="web-based simulation">web-based simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=Platform-as-a-Service%20%28PaaS%29" title=" Platform-as-a-Service (PaaS)"> Platform-as-a-Service (PaaS)</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20application%20development%20%28RAD%29" title=" rapid application development (RAD)"> rapid application development (RAD)</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20genetics" title=" population genetics"> population genetics</a> </p> <a href="https://publications.waset.org/abstracts/20920/scipaas-a-scientific-execution-platform-for-the-cloud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20920.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">590</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">12</span> Integrated Model for Enhancing Data Security Performance in Cloud Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amani%20A.%20Saad">Amani A.

The technology has grown and matured in last half decade and proven their significant role in changing environment of IT infrastructure where cloud services and resources are offered over the network. Cloud technology enables users to use services and resources without being concerned about the technical implications of technology. There are substantial research work has been performed for the usage of cloud computing in educational institutes and majority of them provides cloud services over high-end blade servers or other high-end CPUs. However, this paper proposes a new stack called “CiCKAStack” which provide cloud services over unutilized computing resources, named as commodity computers. “CiCKAStack” provides IaaS and PaaS using underlying commodity computers. This will not only increasing the utilization of existing computing resources but also provide organize file system, on demand computing resource and design and development environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commodity%20computers" title="commodity computers">commodity computers</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud-computing" title=" cloud-computing"> cloud-computing</a>, <a href="https://publications.waset.org/abstracts/search?q=KVM" title=" KVM"> KVM</a>, <a href="https://publications.waset.org/abstracts/search?q=CloudStack" title=" CloudStack"> CloudStack</a>, <a href="https://publications.waset.org/abstracts/search?q=AppScale" title=" AppScale"> AppScale</a> </p> <a href="https://publications.waset.org/abstracts/18221/efficient-utilization-of-commodity-computers-in-academic-institutes-a-cloud-computing-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18221.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">272</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">10</span> Integrated Model for Enhancing Data Security Processing Time in Cloud Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amani%20A.%20Saad">Amani A.

Entering in to cloud services, Librarians can suit the present information handling and they are able to satisfy needs of the knowledge society. Libraries are now in the platform of universalizing all its information to users and they focus towards clouds which gives easiest access to data and application. Cloud computing is a highly scalable platform promising quick access to hardware and software over the internet, in addition to easy management and access by non-expert users. In this paper, we discuss the cloud’s features and its potential applications in the library and information centers, how cloud computing actually works is illustrated in this communication and how it will be implemented. It discuss about what are the needs to move to cloud, process of migration to cloud. In addition to that this paper assessed the practical problems during migration in libraries, advantages of migration process and what are the measures that Libraries should follow during migration in to cloud.

In the scope of preliminary study, three types of samples were investigated including basement phyllite (Bp) overlain by the clay beds, weathered phyllite (Wp) and Doğanhisar clay (Dc). The Chemical Index of Alteration (CIA) values of Dc range from 81 to 88 with an average of 85. This value is higher than that of Post Archean Australian Shale (PAAS) and defines very intense chemical weathering in the source-area. On the other hand, the A-CN-K diagram indicates that Bp underwent high degree post-depositional K-metasomatism. The average reconstructed CIA value of the Bp prior to the K-metasomatism is mainly 81 which overlaps the CIA values of the Wp (83) and Dc (85). Similar CIA values indicate parallel weathering trends. Also, extrapolation of the samples back to the plagioclase-alkali feldspar line in the A-CN-K diagram suggests an identical provenance close to granite in composition. Hereby the weathering background of Dc includes two steps. First one is intense weathering process of a granitic source to Bp with post-depositional K-metasomatism and the latter is progressively weathering of Bp to premetasomatised conditions (formation of Wp) ending with Dc deposition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clay%20beds" title="clay beds">clay beds</a>, <a href="https://publications.waset.org/abstracts/search?q=Doganhisar" title=" Doganhisar"> Doganhisar</a>, <a href="https://publications.waset.org/abstracts/search?q=provenance" title=" provenance"> provenance</a>, <a href="https://publications.waset.org/abstracts/search?q=weathering" title=" weathering"> weathering</a> </p> <a href="https://publications.waset.org/abstracts/49547/provenance-and-paleoweathering-conditions-of-doganhisar-clay-beds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49547.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">308</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">6</span> Design, Modeling and Analysis of 2×2 Microstrip Patch Antenna Array System for 5G Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vinay%20Kumar%20K.%20S.">Vinay Kumar K.

The proposed array of antennas where the phased array antenna systems (PAAS) are used ubiquitously everywhere, from defense radar applications to commercial applications like 5G/6G. Microstrip patch antennae with slot arrays for linear polarisation parallel and perpendicular to the axis, respectively, are fed through transverse slots in the side wall of the circular waveguide and fed through longitudinal slots in the small wall of the rectangular waveguide. The microstrip patch antenna is developed using Ansys HFSS (High-Frequency Structure Simulator), this simulation tool. The maximum gain of 6.14 dB is achieved at 5.3 GHz for a single MSPA. For 2×2 array structure, a gain of 7.713 dB at 5.3 GHz is observed.

Cloud computing dynamically delivers convenient, on-demand access to shared pools of software resources, platform and hardware as a service through internet. The cloud computing model—made promising by sophisticated automation, provisioning and virtualization technologies. Users want the ability to access these services including infrastructure resources, how and when they choose. To accommodate this shift in the consumption model technology has to deal with the security, compatibility and trust issues associated with delivering that convenience to application business owners, developers and users. Absent of these issues, trust has attracted extensive attention in Cloud computing as a solution to enhance the security. This paper proposes a trusted computing technology through Standard Resource parameter Based Trust Model in Cloud Computing to select the appropriate cloud service providers. The direct trust of cloud entities is computed on basis of the interaction evidences in past and sustained on its present performances. Various SLA parameters between consumer and provider are considered in trust computation and compliance process. The simulations are performed using CloudSim framework and experimental results show that the proposed model is effective and extensible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud" title="cloud">cloud</a>, <a href="https://publications.waset.org/abstracts/search?q=Iaas" title=" Iaas"> Iaas</a>, <a href="https://publications.waset.org/abstracts/search?q=Saas" title=" Saas"> Saas</a>, <a href="https://publications.waset.org/abstracts/search?q=Paas" title=" Paas"> Paas</a> </p> <a href="https://publications.waset.org/abstracts/40773/standard-resource-parameter-based-trust-model-in-cloud-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40773.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">330</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">4</span> Geochemical Approach of Rare Earth Element Distribution: A Case Study from Lake Acigol, Denizli, Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Budakoglu">M.

While first stage was completed with 6 ml 37% HCl, 2 ml 65% HNO3 and 1 ml 38-40% HF in an pressure and temperature controlled Teflon beaker using Berghoff Microwave™ at average 135°C, digestion procedure was completed with the addition of 6 ml 5% boric acid solution. REE contents of sediment samples were determined by Perkin Elmer DRC II ICP-MS in Geochemistry Research Laboratories (JAL/GRL) of Faculty of Mines, Istanbul Technical University. Chondrite-normalized REE patterns of Lake Acıgöl sediments show generally high abundance of REE compared to chondritic concentrations, with particular enrichment in LREE [(La/Lu)N = 4.85-19.90], [(La/Lu)N = 7.09-15.14], [(La/Lu)N = 9.42-15.52] and [(La/Lu)N = 7.69-15.63] for the surface sediment and 0-10 cm-, 10-20 cm- and 20-30 cm-subsurface sediments respectively. Also these samples showed flat HREE normalized to chondrite as (La/Sm)N ranging from 2.98 to 4.8 for surface sediments and for subsurface sediments from 3.28 to 3.97 (0-10 cm), 3.57 to 3.94 (10-20 cm) and 3.36 to 3.94 (20-30 cm) while (Gd/Yb)N ranging from 2.14 to 2.93, from 2.03 to 2.76, from 2.26 to 2.79 and from 2.05 to 2.76 from the surface and subsurface sediments respectively. Moreover, their REE profiles are similar to profiles of the continental collision basin (CCB) with negative Eu anomalies. In addition, their REE patterns illustrate generally low abundance of REE compared to concentrations of NASC, PAAS and UCC with very slight enrichment of LREE and positive Eu* anomalies. Therefore there is no comparable between our samples of surface and subsurface sediments and these types of international sediments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chondrite-normalized%20REE%20patterns" title="chondrite-normalized REE patterns">chondrite-normalized REE patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=hypersaline%20lake" title=" hypersaline lake"> hypersaline lake</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20sediments" title=" surface sediments"> surface sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=subsurface%20sediments" title=" subsurface sediments"> subsurface sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=Lake%20Ac%C4%B1g%C3%B6l" title=" Lake Acıgöl"> Lake Acıgöl</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/10632/geochemical-approach-of-rare-earth-element-distribution-a-case-study-from-lake-acigol-denizli-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10632.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">520</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">3</span> An Application Framework for Integrating Wireless Sensor and Actuator Networks for Precision Farming as Web of Things to Cloud Interface Using Platform as a Service</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumaya%20Iqbal">Sumaya Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Aijaz%20Ahmad%20Reshi"> Aijaz Ahmad Reshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advances in sensor and embedded technologies have led to rapid developments in Wireless Sensor Networks (WSNs). Presently researchers focus on the integration of WSNs to Internet for their pervasive availability to access these network resources as the interoperable subsystems. The recent computing technologies like cloud computing has made the resource sharing as a converged infrastructure with required service interfaces for the shared resources over the Internet. This paper presents application architecture for wireless Sensor and Actuator Networks (WSANS) following web of things, which allows easy integration of each node to the Internet in order to provide them web accessibility. The architecture enables the sensors and actuator nodes accessed and controlled using cloud interface on WWW. The application architecture was implemented using existing web and its emerging technologies. In particular Representational State Transfer protocol (REST) was extended for the specific requirements of the application. Cloud computing environment has been used as a development platform for the application to assess the possibility of integrating the WSAN nodes to Cloud services. The mushroom farm environment monitoring and control using WSANs has been taken as a research use case. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=WSAN" title="WSAN">WSAN</a>, <a href="https://publications.waset.org/abstracts/search?q=REST" title=" REST"> REST</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20of%20things" title=" web of things"> web of things</a>, <a href="https://publications.waset.org/abstracts/search?q=ZigBee" title=" ZigBee"> ZigBee</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20interface" title=" cloud interface"> cloud interface</a>, <a href="https://publications.waset.org/abstracts/search?q=PaaS" title=" PaaS"> PaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20gateway" title=" sensor gateway"> sensor gateway</a> </p> <a href="https://publications.waset.org/abstracts/156433/an-application-framework-for-integrating-wireless-sensor-and-actuator-networks-for-precision-farming-as-web-of-things-to-cloud-interface-using-platform-as-a-service" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156433.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">120</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">2</span> A Review on Cloud Computing and Internet of Things </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahar%20S.%20Tabrizi">Sahar S.

Cloud computing is useful to overcome a number of problems in various Information Technology (IT) domains such as Geographical Information Systems (GIS), Scientific Research, e-Governance Systems, Decision Support Systems, ERP, Web Application Development, Mobile Technology, etc. Companies can use Cloud Computing services to store large amounts of data that can be accessed from anywhere on Earth and also at any time. Such services are rented by the client companies where the actual rent depends upon the amount of data stored on the cloud and also the amount of processing power used in a given time period. The resources offered by the cloud service companies are flexible in the sense that the user companies can increase or decrease their storage requirements or the processing power requirements at any time, thus minimizing the overall rental cost of the service they receive. In addition, the Cloud Computing service providers offer fast processors and applications software that can be shared by their clients. This is especially important for small companies with limited budgets which cannot afford to purchase their own expensive hardware and software. This paper is an overview of the Cloud Computing, giving its types, principles, advantages, and disadvantages. In addition, the paper gives some example engineering applications of Cloud Computing and makes suggestions for possible future applications in the field of engineering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title="cloud computing">cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20systems" title=" cloud systems"> cloud systems</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20services" title=" cloud services"> cloud services</a>, <a href="https://publications.waset.org/abstracts/search?q=IaaS" title=" IaaS"> IaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=PaaS" title=" PaaS"> PaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=SaaS" title=" SaaS"> SaaS</a> </p> <a href="https://publications.waset.org/abstracts/71816/a-review-on-cloud-computing-and-internet-of-things" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71816.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">233</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">1</span> Data Confidentiality in Public Cloud: A Method for Inclusion of ID-PKC Schemes in OpenStack Cloud</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Nalini">N.

The core principles of information security are the confidentiality, integrity and availability, also referred as CIA triad. Cloud computing services are classified as SaaS, IaaS and PaaS services. With cloud adoption the confidential enterprise data are moved from organization premises to untrusted public network and due to this the attack surface has increased manifold. Several cloud computing platforms like OpenStack, Eucalyptus, Amazon EC2 offer users to build and configure public, hybrid and private clouds. While the traditional encryption based on PKI infrastructure still works in cloud scenario, the management of public-private keys and trust certificates is difficult. The Identity based Public Key Cryptography (also referred as ID-PKC) overcomes this problem by using publicly identifiable information for generating the keys and works well with decentralized systems. The users can exchange information securely without having to manage any trust information. Another advantage is that access control (role based access control policy) information can be embedded into data unlike in PKI where it is handled by separate component or system. In OpenStack cloud platform the keystone service acts as identity service for authentication and authorization and has support for public key infrastructure for auto services. In this paper, we explain OpenStack security architecture and evaluate the PKI infrastructure piece for data confidentiality. We provide method to integrate ID-PKC schemes for securing data while in transit and stored and explain the key measures for safe guarding data against security attacks. The proposed approach uses JPBC crypto library for key-pair generation based on IEEE P1636.3 standard and secure communication to other cloud services. <p class="card-text"><strong>Keywords:</strong>
