Recommended Background: Java software development

Structural equation modeling (SEM) is a statistical technique that is becoming increasingly popular in the educational and behavioral sciences. SEM allows researchers to test the validity of hypothesized models involving complex relationships among multiple variables. Collected data is used to estimate the parameters of the equations and assessing the fit of the model.

The software required is an application that allows researchers to define their hypothesized models visually and will output the correct syntax for the analytical software of their choosing.

To date a promising functional application has been developed in JAVA by a Computer Science student as a 4080 project. The existing software allows the user to draw a path diagram and outputs code for the R package sem. There are a number of improvements to be made (refinements and additions to graphical user interface) and then the application needs to be extended to output syntax appropriate for additional software applications (openMX, MPlus and EQS). Though this project may not begin at “the first stages” of the software lifecycle, this scenario is likely common in the software development market. In addition, the student will be working with a primary “client” who is far less technically advanced, which is also reflective of real-world situations.

Required Background: General CSE408x prerequisites, familiarity with C++ and Windows software tools

Description The YUsend (York University Space Engineering Nanosatellite Demonstration) Lab has procured a Windows XP-based industrial computer and temperature acquisition card (as well as other hardware) for performing TVAC testing of nanosatellites in the CSIL Lab (PSE 003). A “TVAC Test Manager” application written using LabView's G programming language will oversee the acquisition of temperatures (thermal test outputs) and control of IR lamps (thermal test inputs) during the rather long periods (4 or more days, 24 hours a day) of a TVAC test.

Specific tasks include: 1. Writing temperature acquisition card (OMEGA Engineering CIO-DAS-Temp) drivers for LabView - should be written in Visual C++ or similar and compiled into SubVI format. 2. Write LabView VI's (“Virtual Instrument”) to perform (a) Test set-up activities - checkout of sensor and lamps, assigning neumonics to temperature sensors, setting of alarm conditions for sensors and lamps (b) Acquire and monitor temperature data and control lamp voltage during test, raise operator alarms for temperature or IR lamp anomalous conditions as required © Store temperature and control data for subsequent analysis and reporting. 3. (Optional) Interface the Test Manager with an orbital simulation tool which would be used to compute IR lamp inputs based on a simulation of the nanosatellite's orbital position and attitude (eg - in the sun, lamps on, in eclipse lamps off). The simulation tool is a package called Satellite Toolkit (STK) which has an TCP/IP-based API.

Required Background: Eiffel software development method

Description Game playing frameworks in Eiffel such as Eiffelmedia usually wrap C frameworks in Eiffel. The goal of this project is to develop (initially, a simple) framework using pure Eiffel/EiffelVision so that the framework can be used on any platform (Windows, Linux, Mac) without external dependencies. Games provide a rich source for exploring object oriented software construction and design patterns, so that the framework would be useful in software design courses.

Supervisor: Mike McNamee

Required Background: Good grade in a Numerical Methods course and good knowledge of Fortran, C or similar language.

Description: Write, debug and run several Fortran programs related to solving polynomial equations, with a view to comparing different known methods.

Supervisor: Sotirios Liaskos (liaskos at yorku dot ca)

Required Background: Good knowledge of Unix tools / Python, Perl or Awk. Comfort with algorithms and programming. Essential: 2031 – Software Tools. Desired: 3402 – Functional & Logic Programming, 3101 – Design and Analysis of Algorithms, 4302 – Compilers and Interpreters.

Description: This project involves enriching and integrating a set of fairly complex scripts, which are components of an Artificial Intelligence (AI) planner, and exporting them to the public in a Software-as-a-Service (SaaS) fashion.

The components are various Unix executables and LISP programs that need to interact in complex ways. The components may be residing in different servers in different universities. Currently integration is performed manually, at the expense of usability. Thus, we aim at constructing a module that: (a) integrates involved components to deliver output in one call, (b) exports a unique web interface (preferably following WSDL/SOAP) to be easily accessed by custom front-end tools by anyone, anywhere, (c ) offers a simple front-end for human users.

Learning objectives:

• Understand the technologies and process involved in turning native code into a web-service (“servicizing”).
• Study a state-of-the-art AI planner and understand its workings.
• Exercise scripting skills.

Description: Registration is a fundamental step in image-based surgical navigation. Several (seemingly) different approaches for predicting distance errors in registration are known, but for some surgical procedures, the angular error in registration is more important. This project will validate an approach for predicting angular error in registration; the student will use a combination of simulated and actual registration data for testing purposes.

Description: Tracked pointers are the most common tools used in surgical navigation systems. A typical pointer has a tracked target on one end and a sharp or ball tip on the other end. Finding the location of the tip relative to the target is a calibration problem. One solution to the calibration problem involves pivoting the pointer about the tip while tracking the target; if the tip is kept stationary, then the target moves on the surface of a sphere. Fitting the tracking data to the surface of a sphere yields the location of the tip as the sphere center. Unfortunately, the calibrated tip position obtained using such a spherical calibration has high variance. This project will investigate how much variance there is in the calibrated tip position, and methods for reducing the variance of the calibrated tip position.

Description: One of the major privacy concerns in Online Social Networks is photo sharing. A user may post his/her friends’ photos without their consent. The friends have no control over the user’s Facebook activities, namely photo sharing. In this project, we design and implement a third-party Facebook application that allows people to protect their identities in photos uploaded by another user without their consent.

Required prerequisite background: Proficiency in programming, especially in Java and Web application programming.

Desired prerequisite: Knowledge of image processing, Facebook API, JavaScript Object Notation (JSON)
