Spice: A Software Tool For Studying End-User’S Insecure Cyber Behavior And Personality-Traits, Anjila Tamrakar, Anjila Tamrakar

University of New Orleans Theses and Dissertations

Insecure cyber behavior of end users may expose their computers to cyber-attack. A first step to improve their cyber behavior is to identify their tendency toward insecure cyber behavior. Unfortunately, not much work has been done in this area. In particular, the relationship between end users cyber behavior and their personality traits is much less explored. This paper presents a comprehensive review of a newly developed, easily configurable, and flexible software SPICE for psychologist and cognitive scientists to study personality traits and insecure cyber behavior of end users. The software utilizes well-established cognitive methods (such as dot-probe) to identify number ...

Decelerating I/O Power Management, Shuang Zhai, Felix Xiaozhu Lin 2016 Purdue University

Decelerating I/O Power Management, Shuang Zhai, Felix Xiaozhu Lin

The Summer Undergraduate Research Fellowship (SURF) Symposium

System suspend/resume is crucial to energy proportionality of modern computers, from wearable to cloud servers. Ironically, this OS mechanism itself is slow and energy hungry. Through characterizing the Linux kernel on a variety of modern system-on-chips (SoCs), we show the major reason as slow power state transitions of IO, which keeps CPU waiting. Furthermore, we argue that the IO wait can hardly be reduced to a satisfactory level, because most of slow transitions of IO are bounded by peripherals, low-speed buses, or physical factors. Therefore, the kernel execution for suspend/resume should be offloaded to a miniature core that ...


The Design And Validation Of A Wireless Bat-Mounted Sonar Recording System, Jeremy Joseph Langford 2016 University of Tennessee, Knoxville

The Design And Validation Of A Wireless Bat-Mounted Sonar Recording System, Jeremy Joseph Langford

Masters Theses

Scientists studying the behavior of bats monitor their echolocation calls, as their calls are important for navigation and feeding, but scientist are typically restricted to ground-based recording. Recording bat calls used for echolocation from the back of the bat as opposed to the ground offers the opportunity to study bat echolocation from a vantage otherwise only offered to the bats themselves. However, designing a bat mounted in-flight audio recording system, (bat-tag), capable of recording the ultra-sound used in bat echolocation presents a unique set of challenges. Chiefly, the bat-tag must be sufficiently light weight as to not overburden the bat ...


An Application Of The Universal Verification Methodology, Rui Ma 2016 University of Tennessee, Knoxville

An Application Of The Universal Verification Methodology, Rui Ma

Masters Theses

The Universal Verification Methodology (UVM) package is an open-source SystemVerilog library, which is used to set up a class-based hierarchical testbench. UVM testbenches improve the reusability of Verilog testbenches. Direct Memory Access (DMA) plays an important role in modern computer architecture. When using DMA to transfer data between a host machine and field-programmable gate array (FPGA) accelerator, a modularized DMA core on the FPGA frees the host side Central Processing Unit(CPU) during the transfer, helps to save FPGA resources, and enhances performance. Verifying the functionality of a DMA core is essential before mapping it to the FPGA. In this ...

Implementing A One Address Cpu In Logisim, Charles W. Kann III 2016 Gettysburg College

Implementing A One Address Cpu In Logisim, Charles W. Kann Iii

Gettysburg College Open Educational Resources

Most computer users have an incorrect, but useful, cognitive metaphor for computers in which the user says (or types or clicks) something and a mystical, almost intelligent or magical, behavior happens. It is not a stretch to describe computer users as believing computers follow the laws of magic, where some magic incantation is entered, and the computer responds with an expected, but magical, behavior.

This magic computer does not actually exist. In reality computer are machines, and every action a computer performs reduces to a set of mechanical operations. In fact the first complete definition of a working computer was ...

Electronic Thesis and Dissertation Repository

With the transformation of cloud computing technologies from an attractive trend to a business reality, the need is more pressing than ever for efficient cloud service management tools and techniques. As cloud technologies continue to mature, the service model, resource allocation methodologies, energy efficiency models and general service management schemes are not yet saturated. The burden of making this all tick perfectly falls on cloud providers. Surely, economy of scale revenues and leveraging existing infrastructure and giant workforce are there as positives, but it is far from straightforward operation from that point. Performance and service delivery will still depend on ...

Crowdsourcing Management Education Assessment, Owen P. Hall Jr, Charla Griffy-Brown

Journal of International Technology and Information Management

Assessment is now at the center of the new business education zeitgeist. This focus is the direct result of feedback from the business community regarding the growing gap between their needs and graduates from many business schools. Recently this divide has fallen under even closer scrutiny because of increasing student debt and the growing controversy over return-on- investment. Today business leaders are looking for web-savvy, problem-solving graduates. To this end, AACSB and regional accrediting bodies are calling for the adoption of comprehensive collaborative learning strategies to better align graduates’ skill sets with the real needs of business.

Privacy And The Information Age: A Longitudinal View, Charles E. Downing 2016 Northern Illinois University

Privacy And The Information Age: A Longitudinal View, Charles E. Downing

Journal of International Technology and Information Management

As information systems and data storage capacity become increasingly sophisticated, an important ethical question for organizations is “What can/will/should be done with the personal information that has been and can be collected?” Individuals’ privacy is certainly important, but so is less costly and more targeted business processes. As this conflict intensifies, consumers, managers and policy makers are left wondering: What privacy principles are important to guide organizations in self-regulation? For example, do consumers view the five rights originally stated in the European Data Protection Directive as important? Comprehensive? Is there a product discount point where consumers would forsake ...

An Empirical Investigation On Ceo Turnover In It Firms And Firm Performance, Peiqin Zhang, David Wierschem, Francis A. Mendez Mediavilla, Keejae P. Hong

Journal of International Technology and Information Management

Drawn upon upper echelon theory and organizational theory, this research proposes to examine the impact of CEO turnover in IT firms on firm performance in terms of both sustainable accounting performance and market performance. We find that CEO turnover is a significant determinant of firm performance, especially in IT firms. This paper contributes to the IS literature by investigating the CEO turnover impact in IT firms compared to other industries. This study also has practical implications by providing the guideline for IT firms on the CEO turnover policy. Such firms should place additional emphasis on their succession planning efforts.

On Optimizations Of Virtual Machine Live Storage Migration For The Cloud, Yaodong Yang 2016 University of Nebraska-Lincoln

On Optimizations Of Virtual Machine Live Storage Migration For The Cloud, Yaodong Yang

Computer Science and Engineering: Theses, Dissertations, and Student Research

Virtual Machine (VM) live storage migration is widely performed in the data cen- ters of the Cloud, for the purposes of load balance, reliability, availability, hardware maintenance and system upgrade. It entails moving all the state information of the VM being migrated, including memory state, network state and storage state, from one physical server to another within the same data center or across different data centers. To minimize its performance impact, this migration process is required to be transparent to applications running within the migrating VM, meaning that ap- plications will keep running inside the VM as if there were ...
