One other thing this system does is to prevent CP9 from collecting unnecessary data after launch. Testing was done on this …

Decafs: A Modular Distributed File System To Facilitate Distributed Systems Education, Halli Elaine Meth

Master's Theses

Data quantity, speed requirements, reliability constraints, and other factors encourage industry developers to build distributed systems and use distributed services. Software engineers are therefore exposed to distributed systems and services daily in the workplace. However, distributed computing is hard to teach in Computer Science courses due to the complexity distribution brings to all problem spaces. This presents a gap in education where students may not fully understand the challenges introduced with distributed systems. Teaching students distributed concepts would help better prepare them for industry development work.

Improvement Of Statistical Process Control At St. Jude Medical's Cardiac Manufacturing Facility, Christopher Lance Edwards

Master's Theses

Sig sigma is a methodology where companies strive to reproduce results ending up having a 99.9996% chance their product will be void of defects. In order for companies to reach six sigma, statistical process control (SPC) needs to be introduced. SPC has many different tools associated with it, control charts being one of them. Control charts play a vital role in managing how a process is behaving. Control charts allow users to identify special causes, or shifts, and can therefore change the process to keep producing good products, free of defects.

There are many factories and manufacturing facilities having implemented …

An Interactive Visualization Model For Analyzing Data Storage System Workloads, Steven Charubhat Pungdumri

Master's Theses

The performance of hard disks has become increasingly important as the volume of data storage increases. At the bottom level of large-scale storage networks is the hard disk. Despite the importance of hard drives in a storage network, it is often difficult to analyze the performance of hard disks due to the sheer size of the datasets seen by hard disks. Additionally, hard drive workloads can have several multi-dimensional characteristics, such as access time, queue depth and block-address space. The result is that hard drive workloads are extremely diverse and large, making extracting meaningful information from hard drive workloads very …

Requirements Specification For Dsic: Distribution System For Information And Collaboration, Alex Abrahamian

Computer Science and Software Engineering

There seems to exist an invisible barrier between people that should be connected but for whatever reasons (don't hang out in the same circles, don't go to the same meetings, or are geographically separated) haven't met each other yet.

Normally these people will only meet when others bring them together or they are thrown together on a project. DSIC aims to preempt the person discovery process by allowing a way for people to post ideas, events, and other collaborations in a single place that can then be searched by other users.

The system utilizes postings, user profiles, and a tagging …

Cplop - Cal Poly's Library Of Pyroprints, Kevin Webb

Computer Engineering

California Polytechnic Library of Pyroprints, CPLOP, is a web driven data-base application that stores data from the biology’s departments E. coli Pyrosequencing project. Some of this data was stored in Excel datasheets, while data from the pyrosequencing machines was stored as just a list of random .xml files. There was no useful way to organize and store the massive amounts of data from multiple file sources in one location, nor to perform the complicated searches and comparisons that the project requires. CPLOP’s primary goal is to store such data in three organized tables that relate to one another. It was …

Freeing Space For Nasa: Incorporating A Lossless Compression Algorithm Into Nasa's Fiber Optic Strain Sensing System, Kaitlyn Fiechtner, Allen Parker

STAR Program Research Presentations

NASA’s Fiber Optic Strain Sensing (FOSS) system can gather and store up to 1,536,000 bytes (1.46 megabytes) per second. Since the FOSS system typically acquires hours—or even days—of data, the system can gather hundreds of gigabytes of data for a given test event. To store such large quantities of data more effectively, NASA is modifying a Lempel-Ziv-Oberhumer (LZO) lossless data compression program to compress data as it is being acquired in real time. After proving that the algorithm is capable of compressing the data from the FOSS system, the LZO program will be modified and incorporated into the FOSS system. …
