Whilst a wide variety of different ERAs and RMs have been proposed for different industries and types of business, only few of them have been devoted to the Higher Education (HE) sector. In this paper, we propose an in-depth analysis process which we then critically apply to review, compare and classify 20 existing ERAs and RMs targeted to the HE domain. Our process uses a common set of 12 definitional attributes. In so doing, we contribute to the existing body of knowledge by providing a unified, structured and comprehensive analysis process and catalog of these abstract EA artifacts. With this we aim to create awareness on their potential practical utility and to increase their visibility, transparency and opportunity for their reusability by different HE stakeholders. Hence, the proposed process and catalog is expected to be useful both for practitioners and researchers by providing a panoramic view of more or less ready-to-use existing ERAs and RMs for HE, as well as a structure way to regard them. Moreover, and by specifying their main scope, coverage and extend of knowledge captured, the process and catalog might become a valuable tool for providing guidance to HE stakeholders on making better-informed decisions on the selection of suitable architectural artifacts for being conveniently adapted or applied in different EA practices conducted at their respective institutions.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2018-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85222434","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 order to determine whether deep neural networks are capable of learning this complex aesthetic task, we compare two network frameworks—a classification network, and a conditional generative adversarial network, or cGAN—examining the quality and consistency of their output as potential automated solutions to color correction. Results are very good for both networks, though each exhibits problem areas. The classification network has issues with generalizing due to the need to collect and especially to label all data being used to train it. The cGAN on the other hand can use unlabeled data, which is much easier to collect. While the classification network does not directly affect images, only identifying image problems, the cGAN, creates a new image, introducing potential image degradation in the process; thus multiple adjustments to the network need to be made to create high quality output. We find that the data labeling issue for the classification network is a less tractable problem than the image correction and continuity issues discovered with the cGAN method, which have direct solutions. Thus we conclude the cGAN is the more promising network with which to automate color correction and grading.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2018-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72511810","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}

Understanding how compute jobs are scheduled is necessary for improving the job scheduling strategies in order to optimize cluster utilization and job wait times. This increases the importance of a reliable simulation capability, which in turn requires accuracy and comparability with historic workloads from the cluster. Not all job schedulers have a simulation capability, including the Portable Batch System (PBS) resource manager. Hence, PBS based centers have no direct way to simulate changes and optimizations before they are applied to the production system. We propose and discuss how to run job simulations for large-scale PBS based clusters with the Maui Scheduler. This also includes awareness of node downtimes, scheduled and unexpected. For validation purposes, we use historic workloads collected at the IT4Innovations supercomputing center. The viability of our approach is demonstrated by measuring the accuracy of the simulation results compared to the real workloads. In addition, we discuss how the change of the simulator’s time step resolution affects the accuracy as well as simulation times. We are confident that our approach is also transferable to enable job simulations for other computing centers using PBS.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2018-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90653987","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}

This raises the main question of which construct (user vulnerabilities or phisher skills) has a greater influence on the vulnerable user. Researchers have provided enough evidence of user vulnerabilities, namely the desire for monetary gain, curiosity of the computer user, carelessness on the part of the user, the trust placed in the purported sender by the user, and a lack of awareness on the part of the computer user. However, there is a lack of research on the magnitude of each of these factors in influencing an unsuspecting user to fall for a phishing or spear phishing attack which we explored in this paper. While user vulnerabilities pose major risk, the effect of the spear phisher’s ability in skillfully crafting convincing emails (using fear appeals, urgency of action, and email contextualization) to trap even skillful IT security personnel is an area that needs to be explored. Therefore, we explored the relationships between the two major constructs namely ‘user vulnerabilities’ and ‘email contextualization’, through the theory of planned behavior with the objective to find out the major factors that lead to computer users biting the phishers’ bait. In this theoretical version of the paper, we provided the resulting two constructs that needed to be tested.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2018-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90172557","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}
