However, it is not suitable for Virtual Machines (VMs) running computation-intensive and memory-intensive workloads because its operational behaviors depend on a configuration parameter, namely the maximum tolerable downtime. Although the default value of this parameter is good enough for normal web-based applications, it is too low for most HPC applications, which are computation-intensive and memoryintensive. Performing a migration with an inappropriate parameter may cause extensively long migration time or downtime. Defining this parameter is nontrivial since application workloads are generally unpredictable. This difficulty also makes it hard for cloud management systems to operate VM live migration automatically. In this paper, we propose the Memory-bound Pre-copy Live Migration (MPLM) mechanism that performs VM live migration without requiring the maximum tolerable downtime parameter. MPLM presents a new perspective of VM live migration, where the migration is performed based on the present state of VM computation without enforcing downtime constraints. During live migration, MPLM separates memory pages into dirty and non-dirty sets and transmits them in a multiplexing manner. MPLM has been implemented in a modified version of the QEMU-KVM software. Experiments have been conducted to evaluate MPLM performances against those of the traditional pre-copy mechanism. We performed a number of live migrations of VMs running four OpenMP NAS Parallel Benchmark programs. Experimental results show that MPLM is more efficient and easier to use than the pre-copy mechanism.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127663453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we focus on virtualizing IMS by enabling network function virtualization (NFV). NFV virtualizes network functions into software applications. The virtualized network functions can be decomposed into smaller functional blocks which will enable a high level of elasticity. This paper proposes an NFV-based virtualized IMS (vIMS) architecture that decomposes the S-CSCF into two key functions: one handles the UE registration (registration; R) and the other processes the call control (call control; C). Then the original I-CSCF is combined with the registration function (R), denoted by vI-CSCF(R). The S-CSCF reserves the call control function (C) only, denoted by vS-CSCF(C). We also design the registration procedure and call setup procedure in the vIMS. The vI-CSCF(R) is responsible for the original I-CSCF function and UE registration; thus, the vS-CSCF(C) is offloaded without handling any UE registration message. In addition, we analyze the queuing delay time of registration and call setup in the NFV-based vIMS architecture. Compared with the straightforward solution for IMS virtualization, our proposed vIMS has shorter delay time of registration and call setup by improving the S-CSCF's performance. In order to verify the feasibility of our proposal, we developed and deployed our proposed vIMS and the Clearwater-vIMS with OpenStack and Clearwater software, and run the stress test on them respectively. Compared to the original Clearwater-vIMS, our proposed vIMS have higher registration success rate and call setup success rate.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125136581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, behind this convenience lie information security risks. Many people have attempted to claim other people's documents as their own via theft or alteration. So information transmission protection and certification have become critical issues. In this study, we used the frequency domain to encrypt and hide certification information. We adopted the wavelet transform method to transform the images from the spatial domain into the frequency domain, used RC4 to perform stream encryptions for the visually sensitive LL area, employed reversible information hiding for the LH, HL, and HH areas using the pixel value ordering (PVO) method and permuted the LH, HL, and HH areas to improve the level of security. Finally, we outputted the file using the ZIP compression format. The results indicated that our method provides a good visual encryption effect by enabling users to correctly extract and remove the certification information as well as certify the decrypted image.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134362449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, because of the development of rapid prototyping, the rise of open-source hardware and programming languages, the popularization of network communities, and the establishment of maker spaces, DIY has been taken to the next level: “co-creation.” This concept requires reform to the standard curriculum in information and technology education. Therefore, this study aims to define the key competences of makers to construct the competence indicators of Maker Education for information and technology education in elementary school. On this basis, a curriculum can be developed, and an evaluation system for learning effectiveness can be built to equip students with the abilities to adapt to life and tackle challenges. In this study, the Fuzzy Delphi Method (FDM) was applied to collect and analyze data in the form of a questionnaire survey. The subjects were 12 experts from enterprises, governmental institutions, schools and research institutes. The research achievements include 3 factors (“Theoretical knowledge,” “Practical application,” “Maker's mindset”), and 10 indicators.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115263743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The warning system, as a whole, consists of the sensors and a microcontroller integrated into the undergarment through e-textile technology, and a wireless monitoring device. Measured data are wirelessly transmitted and received by the monitoring device capable of data visualization and are intended to be used by an operation chief to monitor a firefighter. When monitored data exceed a certain threshold value the firefighter will be notified by means of a light and sound alarm. The system performed well when tested against specific digital sensors and withstood moisture exposure tests. Wireless communication was consistently established to the monitoring device.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114697916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
