10/21/2023 0 Comments Matlab log4jIs there a problem using log4j2 from within Matlab?Įdit: I believe this is related to the inbuilt usage of log4j in Matlab for Matlab's own internal logging. I have no configuration file defined, I expected log4j to give me the default configuration and log to the console (as per log4j2 docs) This.logger = LogManager.getLogger(m圜lassNameAsString) īut when I inspect the Logger object I see: K> this.logger In my Matlab class constructor I: import 4j.LogManager I have added and to my Matlab java classpath. ![]() More project proposals may be added here in the first week of fall term.I'm trying to switch from log4j 1.2 to log4j 2 in a Matlab application. Experience with board level implementations and knowledge of microstrip lines would be helpful, otherwise the basics would have to be picked up during the project. Required Background A background in undergraduate-level electronics is very important. This radar circuit is ultimately intended to be positioned on a rover doing ground analysis. The receiver would be a time-shifted sampler, used to sample the returning pulses in progressive periods. The bandwidth of the signal is roughly 2-8 GHz and hence requires very careful board layout. On the transmitter side the board would take a 5- MHz input clock, run it through a series of off-the-shelf amplifiers and then through a shaping circuit that would convert the input into an outgoing series of pulses (still at 5- MHz repetition rate) less than 400-ps in duration each. The students would have to design microwave boards for the high-frequency components of this unit, on both the transmitter and the receiver. Then he/she will implement a monitoring/debugging framework using the selected instrumentation library.ĭescription: The project requires the construction of components for a ground penetrating radar. ![]() The student(s) will first evaluate the pros and cons on various binary instrumentation libraries (e.g., ASM and PIN). This project aims to explore the feasibility of leveraging binary instrumentation to automatically monitor and debug the behavior of these field systems. Binary instrumentation is a program analysis technique, which can add additional monitoring points without modifying or restarting the system. On other hand, although profilers (e.g., JProfiler and DTrace) can provide detailed information on the internal system behavior, it is not feasible to run them with the field systems due to their high overhead. On one hand, many existing monitoring tools (e.g., PerfMon and pidstat) mainly focus on the high level resource usage data (e.g., CPU and memory). It is essential to monitor the behavior of these systems in the field and troubleshoot problems whenever they arise. Short Description: Many large scale software systems ranging from e-commerce websites (e.g., eBay) to telecommunication infrastructures (e.g., AT&T) are required to be available and ready to service by millions of users all the time. Required Background: Good programming skills (especially in Java) Good analytical and communication skills Interested in large complex software systems and automated software analysis. Supervisor:Zhen Ming (Jack) Jiang (zmjiang at cse dot yorku dot ca) Hunting for Bugs in Logging: applying JPF to log4j Modify these algorithms to improve performance on these datasets Evaluate current attentive algorithms on these datasetsģ. The student will work with senior graduate students, postdoctoral fellows and research scientists to help modify the attentive sensing technology to operate in these domains. The general problem is to use attentive sensing technology ( to visually detect and track multiple moving agents (e.g., skiers, riders, horses) and to select specific agents for active high-resolution smooth pursuit. ![]() ![]() Specific application domains under investigation include skiing, indoor BMX parks, and horse tracks. The goal of this project is to modify York University’s patented attentive sensor technology to the sport video recording market. Required Background: Good programming skills Good math skills Knowledge of C and MATLAB programming languages
