Pthreads Profiler, Ryan Van Quinlan
Pthreads Profiler, Ryan Van Quinlan
Computer Science and Software Engineering
The goal of this senior project was to design and implement a program which would allow users to profile programs that utilize the Pthreads library. This profiler allows users to measure load balance and lock contention between threads as well as discover deadlocks. These tools can be essential to developers of multi-threaded applications, which are notoriously difficult to debug. Additionally, this tool can help find vital performance benefits by providing relative execution measurements. The profiler is written in C++ and utilizes the standard template library as well as glibc extensions.
Design And Implementation Of Digital Information Security For Physical Documents, Pengcheng Wang
Design And Implementation Of Digital Information Security For Physical Documents, Pengcheng Wang
Masters Theses
The objective of this thesis is to improve the security for physical paper documents. Providing information security has been difficult in environments that rely on physical paper documents to implement business processes. Our work presents the design of a digital information security system for paper documents, called "CryptoPaper", that uses 2-dimensional codes to represent data and its security properties on paper. A special scanner system is designed for "CryptoPaper" which uses image recognition techniques and cloud-based access control to display plaintext of encrypted and encoded data to authorized users.
Hardware/Software Interface Assurance With Conformance Checking, Li Lei
Hardware/Software Interface Assurance With Conformance Checking, Li Lei
Dissertations and Theses
Hardware/Software (HW/SW) interfaces are pervasive in modern computer systems. Most of HW/SW interfaces are implemented by devices and their device drivers. Unfortunately, HW/SW interfaces are unreliable and insecure due to their intrinsic complexity and error-prone nature. Moreover, assuring HW/SW interface reliability and security is challenging. First, at the post-silicon validation stage, HW/SW integration validation is largely an ad-hoc and time-consuming process. Second, at the system deployment stage, transient hardware failures and malicious attacks make HW/SW interfaces vulnerable even after intensive testing and validation. In this dissertation, we present a comprehensive solution for HW/SW interface assurance over the system life cycle. …

All Capstone Projects
InstaMapp is a web application we started building in fall 2014. This application is intended for anyone who wants to locate a product from a department store. Anyone who would like to print or view a shopping list with aisle or department locations. Currently there isn’t a reliable application out that that exist in the technology space. InstaMapp currently integrates with Walmart’s API and supports a responsive design for mobile devices.
During fall 2014, we built a proof of concept on Microsoft Windows Azure websites integrating with Intel Mashery Services for the API. We used the following Languages: PHP, JQuery, …

In general, server rooms have restricted access requiring that staff possess access codes, keys, etc. Normally, only administrators are provided access to protect the physical hardware and the data stored in the servers. Servers also have firewalls to restrict outsiders from accessing them via the Internet. Servers also cost a lot of money. For this reason, server rooms also need to be protected against overheating. This will prolong the lifecycle of the units and can prevent data loss from hardware failure.
The California State University San Bernardino (CSUSB), Specifically the College of Arts and Letters server room has faced power …
