Automated Program Profiling And Analysis For Managing Heterogeneous Memory Systems, Adam Palmer Howard

Masters Theses

Many promising memory technologies, such as non-volatile, storage-class memories and high-bandwidth, on-chip RAMs, are beginning to emerge. Since each of these new technologies present tradeoffs distinct from conventional DRAMs, next-generation systems are likely to include multiple tiers of memory storage, each with their own type of devices. To efficiently utilize the available hardware, such systems will need to alter their data management strategies to consider the performance and capabilities provided by each tier.

This work explores a variety of cross-layer strategies for managing application data in heterogeneous memory systems. We propose different program profiling-based techniques to automatically partition program allocation …

Insight2: An Interactive Web Based Platform For Modeling And Analysis Of Large Scale Argus Network Flow Data, Hansaka Angel Dias Edirisinghe Kodituwakku

Masters Theses

Monitoring systems are paramount to the proactive detection and mitigation of problems in computer networks related to performance and security. Degraded performance and compromised end-nodes can cost computer networks downtime, data loss and reputation. InSight2 is a platform that models, analyzes and visualizes large scale Argus network flow data using up-to-date geographical data, organizational information, and emerging threats. It is engineered to meet the needs of network administrators with flexibility and modularity in mind. Scalability is ensured by devising multi-core processing by implementing robust software architecture. Extendibility is achieved by enabling the end user to enrich flow records using additional …

Shakespeare In South Africa: An Examination Of Two Performances Of Titus Andronicus In Apartheid And Post-Apartheid South Africa, Erin Elizabeth Whitaker

Masters Theses

The works of William Shakespeare are wide and universal. His work has been and is still consistently performed in numerous countries and venues across the globe. This thesis focuses on two performances of Titus Andronicus, one of Shakespeare’s most controversial plays, in South Africa. One performance, directed by Dieter Reible in 1970, was produced during apartheid. The second, directed by Gregory Doran, was performed in 1995, just after the end of apartheid. These performances of Titus not only show the versatility and universality of Shakespeare’s work, but the complexity of audience reception and directorial intention in different political landscapes. …

The Performance Of Light: Exploring The Impact Of Natural Lighting In The New Umass School Of Performance, Dylan Brown

Masters Theses

This thesis explores how natural light can be integrated with built form to create a “performance of light” in architecture. Lighting conditions from a contemporary dance piece, as well as other architectural precedents, were studied, and aspects adapted into the building’s design. In addition to designing theatrical effects of light, the classroom and administrative spaces were designed to take advantage of natural light. Daylight studies were used to inform glazing design and material selection to stay within illuminance thresholds in the spaces.

This project is responding to the facility needs of the campus of UMass Amherst where the program of …

The Effects Of Feedback Modality On Performance, Garrett D. Warrilow

Masters Theses

Giving employees information about their performance is a common method for employers seeking to improve or change performance. With the popularity of the internet and computers feedback today is often provided through emails, text messages, and video meetings. While feedback has continued to evolve within and across organizations little has been done to assess the impact its delivery through various modalities has. This study explored and evaluated the relationship between the modality which objective feedback is delivered, and the differential effects it produced on performance of a check entering task. This experiment was a laboratory study employing a between-group repeated …

Analysis Of Outsourcing Data To The Cloud Using Autonomous Key Generation, Mortada Abdulwahed Aman

Masters Theses

"Cloud computing, a technology that enables users to store and manage their data at a low cost and high availability, has been emerging for the past few decades because of the many services it provides. One of the many services cloud computing provides to its users is data storage. The majority of the users of this service are still concerned to outsource their data due to the integrity and confidentiality issues, as well as performance and cost issues, that come along with it. These issues make it necessary to encrypt data prior to outsourcing it to the cloud. However, encrypting …
