Open Source, Modular Platforms, And The Challenge Of Fragmentation, Christopher S. Yoo Nov 2016

Open Source, Modular Platforms, And The Challenge Of Fragmentation, Christopher S. Yoo

Faculty Scholarship at Penn Law

Open source and modular platforms represent two powerful conceptual paradigms that have fundamentally transformed the software industry. While generally regarded complementary, the freedom inherent in open source rests in uneasy tension with the strict structural requirements required by modularity theory. In particular, third party providers can produce noncompliant components, and excessive experimentation can fragment the platform in ways that reduce its economic benefits for end users and app providers and force app providers to spend resources customizing their code for each variant. The classic solutions to these problems are to rely on some form of testing to ensure that the ...


Design Of A Low-Cost Wireless Nirs System With Embedded Linux And A Smartphone Interface, Diogo Da Silva Dias Oct 2015

Design Of A Low-Cost Wireless Nirs System With Embedded Linux And A Smartphone Interface, Diogo Da Silva Dias

Nasser Kashou

Wireless near-infrared spectroscopy (NIRS) systems can help to reduce movement artifacts, and distraction due cables. Utilizing Embedded Linux (EL) can reduce size, development time, cost of a project and allow portability. The goal of this project is to develop a low-cost wireless small-sized NIRS system using EL and a Smartphone as the interface. This was achieved using a BeagleBone Black (BBB) with a deployed custom EL that: (1) controls two sources, (2) receives data from photodetectors (PDs), (3) processes, stores and transmits data via Bluetooth to an Android Smartphone. This device was implemented in under US$150 and its dimension ...


Cplop - Cal Poly's Library Of Pyroprints, Kevin Webb Dec 2011

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 ...


Bluetooth "Clicker": Response Pads For Large Classes, Using Bluetooth Devices, Dana Goyette Jun 2010

Bluetooth "Clicker": Response Pads For Large Classes, Using Bluetooth Devices, Dana Goyette

Computer Engineering

When teaching classes with many students, many teachers opt to use “Clicker” devices to electronically poll students. This project aims to replace these “Clicker” devices with standard Bluetooth devices. The overall goal of this project is to create a framework for two-way communications between a base station and multiple remote devices.


Rfid Asset Tracking And Digital Check-Out System, Jeffrey (Jeff) Migliore Jun 2010

Rfid Asset Tracking And Digital Check-Out System, Jeffrey (Jeff) Migliore

Computer Engineering

An asset tracking and digital check-out system was developed using Radio Frequency Identification (RFID) and a Single Board Computer (SBC). A RFID reader was used as a check point to process transactions. The RFID reader was attached to the SBC via USB. The SBC is integrated into a network via Ethernet and hosts a web graphical user interface (GUI) frontend for users to view transactions and query availability of assets. A MYSQL database was used for the backend storage of data.

Specifically, this system was designed to track tool assets. Many modern companies have employees sharing limited resources. The common ...
