Current techniques enable attackers to exploit vulnerabilities at the micro-architecture level to build side channels. A typical example is the use of the Flush+Reload technique in the Meltdown attack [1]. This paper proposes the detection of malicious loop activities within the Flush+Reload programs through the introduction of a new classification technique. Most current detection models, approach the side channel attacks, by relying on the correlation between attacker and victim programs through the use of machine learning algorithms. This paper differs from such models. It solely analyse the malicious loop activities inside the Flush+Reload attack program and does not seek to synchronise victim and attacker programs. The model proposed has the ability to classify Flush+Reload attacks with a level of accuracy approaching 99% for native and 96% for cloud systems without increasing the cost of detection in a cloud systems above that in native systems.","PeriodicalId":308784,"journal":{"name":"2018 UKSim-AMSS 20th International Conference on Computer Modelling and Simulation (UKSim)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123011407","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 major problem so far with the Electric Vehicles are overloading the Distribution Grids and availability of enough charging stations. The main objective of this research is to design and install a solar powered charging station for EVs in the UAE environment. This research aims to focus on the need for the shifting from the traditional gas and petrol vehicles to Electric vehicles in the UAE. Additionally, the project intends to ease the problem of the additional load that these EVs impose on the grid by powering the charging station from solar energy. This will help evolve the existing transport system of the UAE into a cleaner and greener system. The project is divided mainly into three important parts. First of all, the system components are designed to match with the ratings of available most common EVs. Then the system has been modelled in DIgSILENT Power factory for the simulation and validation of design. Finally, the results from calculations and simulations are described and compared.","PeriodicalId":308784,"journal":{"name":"2018 UKSim-AMSS 20th International Conference on Computer Modelling and Simulation (UKSim)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123980795","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}

Chance corrected agreement coefficients such as the Cohen and Fleiss Kappas are commonly used for this purpose, though the way that they estimate the probability of agreement 'by chance' has been strongly questioned. Alternatives have been proposed, such as the Aickin Alpha coefficient and the Gwet AC1 and AC2 coefficients which are gaining currency. A well known paradox illustrates deficiencies of the Kappa coefficients which, it is claimed, are remedied by an approach which grades the subjects according to their probability of being hard to score. The AC1 and AC2 coefficients result from the application of this grading to the Brennan-Prediger coefficient which may be considered a simplified form of Kappa. This paper questions the rationale of the hardness probability used by AC1 and proposes an alternative approach that may be applied to weighted and unweighted multi-rater Cohen and Fleiss Kappas and also Intra-Class Correlation (ICC) coefficients.","PeriodicalId":308784,"journal":{"name":"2018 UKSim-AMSS 20th International Conference on Computer Modelling and Simulation (UKSim)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125179637","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 distribution of the resources to the various tasks forms a job. The aggregation of the tasks within the job, determine the optimal utilization of the resources and minimal completion time and costs. This paper demonstrates the scheduling problem in the grid applications, considering single-grid and multi-grid environments. Petri Net is used for modeling the system, and the models are implemented with the GPenSIM tool. Also, this paper presents an algorithm for scheduling in multi-grid, in which the modules give the right to each other to use one others resources without causing delays. The novelty of this algorithm is that while it is easy to implement, it is also efficient as it minimizes the total processing time of the jobs.","PeriodicalId":308784,"journal":{"name":"2018 UKSim-AMSS 20th International Conference on Computer Modelling and Simulation (UKSim)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129032711","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 the process of implementation, some links are heavily utilized and have little or no bandwidth available while others carry little or no traffic. Without the process of TE, there are possibilities of having under-utilization and over-utilization problems of bandwidth resources along the links. It is necessary to consider the implementation that would avoid the goal of network design and unguaranteed bandwidth delivery. This paper mainly focuses on Performing Evaluation of Label Distribution Protocol (LDP) Signaling using dynamic MPLS Label Switch Paths (LSPs) and Bandwidth Allocation for sustainable Wired and Wireless Networks. This will make provision of bandwidth allocation possible by the implementation of the Constraint-based LDP with basic configurations. The network model designed will be used for this purpose by the means of the simulation approach. The MPLS model flow analysis will be presented to justify the implementation of LDP. It will likely yield to maximize bandwidth utilization, minimize the packet delay/packet loss in the network and support QoS resource management.","PeriodicalId":308784,"journal":{"name":"2018 UKSim-AMSS 20th International Conference on Computer Modelling and Simulation (UKSim)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121428559","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 spectrum is a scarce resource and requires to be utilized in an efficient way. Research in this domain has envisaged that the problem of spectrum scarcity can be addressed by Cognitive Radio. Cognitive Radio Networks are comprised of multiple technologies and networks which permits the dynamic use of spectrum. Spectrum Handoffs, is thus a major necessity of Cognitive Radio Network and if not properly executed, might cause ping-pong effect. The Ping-pong effect is caused due to the motion of mobile users between boundaries of adjacent cells thus, initiating unnecessary Spectrum Handoffs. In this paper, a Fuzzy Logic based system is proposed that is capable of making efficient decisions about the execution of Spectrum Handoffs thus, and reduces the chances of the ping-pong effect.","PeriodicalId":308784,"journal":{"name":"2018 UKSim-AMSS 20th International Conference on Computer Modelling and Simulation (UKSim)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125819850","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 compare two different evolution paths, where the networks to be merged are separately upgraded to cover the whole traffic demand or a single network is optimized as the result of the merger (Build vs Merge). Our preliminary analyses show that the Merge approach may lead to 50% higher costs, due in particular to the high costs borne to switch off redundant access points. Any Build vs Merge decision should therefore consider the sunk costs due to the inherited networks, as well as the possible benefits associated to a merger.","PeriodicalId":308784,"journal":{"name":"2018 UKSim-AMSS 20th International Conference on Computer Modelling and Simulation (UKSim)","volume":"36 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120901428","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 recent years, abundant of data of rotating equipment is readily available from various sources. However, these data are not being utilized and analyzed for improving maintenance performance. This requires advanced techniques to analyze a variety of data in order to transform into relevant information. Most problems with a lot of parameters involved were not being specific to analyze the contribution of motor failure. Therefore, this research proposed an efficient data analysis using Principle Component Analysis (PCA) in determining the most influential factor to the failure of the industrial motor.

Current song recommendation software that uses playlists has shown to either be inaccurate or suggest songs that are extremely like those in the playlist already. Furthermore, this recommendation software tends to rely very large numbers of records. AI models are used to overcome these limitations using substantially less data. A collaborative filtering approach using two different models (K- means and hierarchical clustering) is used to separate playlist data into clusters for comparison. After the data has been clustered, a Euclidean distance measure is used between the songs in the cluster and the average values of the songs in a single users playlist to make the final predictions. The use of normalisation and PCA enabled the K-means and hierarchical clustering models to form clusters efficiently. When tested on a small sample of users, the system recommended songs that were considered likeable by the users 60% of the time, while still finding songs that were generally diverse.","PeriodicalId":308784,"journal":{"name":"2018 UKSim-AMSS 20th International Conference on Computer Modelling and Simulation (UKSim)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124730268","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}
