Voltage Droop Analysis And Mitigation In Sttram-Based Last Level Cache, Radha Krishna Aluru

USF Tampa Graduate Theses and Dissertations

Preferred especially for a Last Level Cache (LLC) due to its high retention and tolerance capabilities, Spin-Transfer Torque Random Access Memory (STTRAM) is an emerging and a promising Non-Volatile Memory (NVM) technology. To switch the magnetization of a Magnetic Tunnel Junction (MTJ), the amount of current needed is very high (~100μA per bit). For a full cache line (512-bit) write, this extremely high current results in a voltage droop in the conventional cache architecture. Due to this droop, the write operation fails especially when the farthest bank of the cache is accessed. In this thesis, we perform an analysis of …

Supporting Sensemaking Of Complex Objects With Visualizations: Visibility And Complementarity Of Interactions, Kamran Sedig, Paul Parsons, Hai-Ning Liang, Jim Morey

All Works

Making sense of complex objects is difficult, and typically requires the use of external representations to support cognitive demands while reasoning about the objects. Visualizations are one type of external representation that can be used to support sensemaking activities. In this paper, we investigate the role of two design strategies in making the interactive features of visualizations more supportive of users’ exploratory needs when trying to make sense of complex objects. These two strategies are visibility and complementarity of interactions. We employ a theoretical framework concerned with human–information interaction and complex cognitive activities to inform, contextualize, and interpret the effects …

Scalable Clustering Using The Dempster-Shafer Theory Of Evidence, Alireza Chakeri

USF Tampa Graduate Theses and Dissertations

Clustering large data sets has become very important as the amount of available unlabeled data increases. Single Pass Fuzzy C-Means (SPFCM) is useful when memory is too limited to load the whole data set. The main idea is to divide dataset into several chunks and to apply fuzzy c-means (FCM) to each chunk. SPFCM uses the weighted cluster centers of the previous chunk in the next data chunks. However, when the number of chunks is increased, the algorithm shows sensitivity to the order in which the data is processed. Hence, we improved SPFCM by recognizing boundary and noisy data in …

Network Forensic Investigation Of Internal Misuse/Crime In Saudi Arabia: A Hacking Case, Abdulrazaq Al-Murjan, Konstantinos Xynos

Annual ADFSL Conference on Digital Forensics, Security and Law

There are ad-hoc guidelines and a limited policy on computer incident response that does not include computer forensic preparation procedures (e.g. logging incidents). In addition, these guidelines do not consider the requirement of Islamic law for admissible evidence at an organisational level in Saudi Arabia. Network forensic investigation might breach the Saudi law if they follow ad-hoc or international digital forensic standards such as Association of Chief Police Officers (ACPO) guidelines. This might put the organisation in a costly situation when a malicious employee sues an Islamic court. This is because the law of Saudi Arabia is complying with Islamic …
