Virtual Sound Level Meter for analyzing calibrated sound files
This project is the MATLAB development of a virtual sound level meter. The program will read in a calibrated .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. The software implements Fast, Slow, Impulse and LEQ; A, C and Flat Weighting; Ln and Noise Dose analysis; Octave and 1/3 Octave band analysis; high resolution FFT analysis and spectrograms. Band analysis can be made using fast FFT methods or slower, but ANSI standard methods. Source code requires MATLAB + Signal Processing Toolbox. Developed under MATLAB R2010a (but might work with some earlier versions) Executable version does not require MATLAB and runs under Windows XP, Vista, and Windows 7.

Testing images for scientific purposes
The TESTIMAGES archive is a huge and free collection of sample images designed for analysis and quality assessment of different kinds of displays and image processing techniques. The archive includes more than 2 million images originally acquired and divided in three different categories: SAMPLING and SAMPLING_PATTERNS (aimed at testing resampling algorithms), COLOR (aimed at testing color rendering on different displays) and PATTERNS (aimed at testing the rendering of standard geometrical patterns). Please cite the following papers when using any image in this archive: * ASUNI N, GIACHETTI A, "TESTIMAGES: A Large Data Archive For Display and Algorithm Testing", Journal of Graphics Tools, Volume 17, Issue 4, 2015, pages 113-125, DOI:10.1080/2165347X.2015.1024298 * ASUNI N, GIACHETTI A, "TESTIMAGES: a large-scale archive for testing visual devices and basic image processing algorithms", STAG - Smart Tools & Apps for Graphics Conference, 2014.
CSV Comparator is a tool for comparing files which contain CSV-Data.
CSV Comparator is a tool for comparing files which contain CSV-Data. It was created for performance engineers to be able to have a easy way to compare data from two testruns and be able to automate the comparing process of various files with scripts. There is a command line tool as well as a user interface. In case you need to compare .xml-Files you can convert them to .csv-Files with my other project CSV Transformer. The advantages by using CSV as input and output are the following: - Many applications allow an export of its data to CSV or Excel(were it could be saved to CSV) - It is possible to pre- and postprocess the data, e.g removing version numbers before comparing - It is easy to create CSV data from logfiles and other resources by using unix tools like sed or awk - CSV can be loaded into other applications, especially Excel, were it can be formatted by macros for analyzing.

Advanced mission simulation and analysis tool
The Orbit Determination Toolbox (ODTBX) is developed by the Navigation & Mission Design branch at NASA Goddard Space Flight Center as an advanced mission simulation and analysis tool used for concept exploration, proposal, early design phase, and/or rapid design center environments. ODTBX functions and utilities are combined in a flexible architecture that allows for modular development of navigation algorithms and simulations. The core ODTBX functionality is realized through a set of estimation commands that incorporate Monte Carlo data simulation, linear covariance analysis, and measurement processing at a generic level.

Java Disk Benchmark Utility
Simple Java utility to help bench mark disk IO. Benchmark is done by creating and reading data files to a user directory that can be configured. Suggestions would be very appreciated. https://gitlab.com/jamesmarkchan/jDiskMark/ Note: When doing a combined read and write operation the disk cache is not cleared automatically so the app must be restarted to avoid the cache from affecting read IO performance.
Unique finds patterns in source code. It helps you build better software by finding pieces of code that could benefit from a refactoring.
itom - an Open Source Measurement, Automation and Evaluation Software
itom is an open source software suite for operating measurement systems, laboratory automation and data evaluation. One main application of itom is the development and operation of sensor and measurement system for instance in a laboratory environment. Therefore, the software has to be able to communicate with a wide range of different hardware systems, such as cameras or actuators and should provide a diversified and as complete as possible set of evaluation and data processing methods. Additionally, the rapid prototyping of modern measurement and inspection setups requires a system, where parameters or components can easily be changed at runtime, necessitating the availability of an embedded scripting language. Finally, when operating a measurement system, it is also desirable to extend the graphical user interface by system adapted dialogs and windows. https://itom.bitbucket.io/

Python GUI program to work with Geiger counters like GMC-300/320/500
GeigerLog is a Python based GUI program to work with GQ Electronic's GMC-300 / 320 and now also GMC-500 Geiger counters. Available as "scripts" to run where a proper Python environment exists, or as "bundle", which brings its own Python environment (but currently runs on Linux only). GeigerLog allows reading of Geiger counter data, logging to file, printing to screen and plotting as graph, showing Count Rate vs. Time, both in various, selectable units. The history stored on the Geiger counter's internal memory can be extracted, analyzed and graphed in the same way. The graph is live auto-updated and allows various customization. Time ranges for analysis can be set manually or per left/right mouse click. GeigerLog can control some functions of a connected counter (limited to GMC-3xx counters!). Advanced analysis of the data now permits count rate histograms with Poisson fit for quality control of data, and FFT analysis for any periodic signal hidden within the data.
Spatially Oriented Format for Acoustics
In this project we work on the (S)patially (O)riented (F)ormat for (A)coustics: SOFA. The file format is intended for reading, saving, and describing spatially oriented data of acoustic systems. Examples of data we consider are head-related transfer functions (HRTFs), binaural room impulse responses (BRIRs), multichannel measurements such as done with microphone arrays, or directionality data of loudspeakers. The format specifications are the major issue, but we also aim in providing APIs for reading and writing the data in SOFA.

Vessel Simulator Program
Vessel Simulator Program ------------------------ Java program that simulates a vessel moving on the face of the earth. Assuming you have all the prerequisites installed you can run the program either directly from eclipse or just download the JAR file and go "java -jar <name_of_jar_file.jar>" Tell your navigation software/whatever to connect to port 2222 of your machine. NMEA 0183 sentences are sent out from the simulation on port 2222. In the GUI slide up the speed slider (vertical) to start moving and steer using the steering slider (horizontal). Currently there is no facility to move vertically. The altitude is set at initialization and remains where set. Prerequisites ------------- Java of a reasonably current vintage.
