Purpose: To provide a single open-source platform for comprehensive MR algorithm development inclusive of simulations, pulse sequence design and deployment, reconstruction, and image analysis. Methods: We integrated the "Pulseq" platform for vendor-independent pulse programming with graphical programming interface (GPI), a scientific development environment based on Python. Our integrated platform, Pulseq-GPI, permits sequences to be defined visually and exported to the Pulseq file format for execution on an MR scanner. For comparison, Pulseq files using either MATLAB only ("MATLAB-Pulseq") or Python only ("Python-Pulseq") were generated. We demonstrated three fundamental sequences on a 1.5 T scanner. Execution times of the three variants of implementation were compared on two operating systems. Results: In vitro phantom images indicate equivalence with the vendor supplied implementations and MATLAB-Pulseq. The examples demonstrated in this work illustrate the unifying capability of Pulseq-GPI. The execution times of all the three implementations were fast (a few seconds). The software is capable of user-interface based development and/or command line programming. Conclusion: The tool demonstrated here, Pulseq-GPI, integrates the open-source simulation, reconstruction and analysis capabilities of GPI Lab with the pulse sequence design and deployment features of Pulseq. Current and future work includes providing an ISMRMRD interface and incorporating Specific Absorption Ratio and Peripheral Nerve Stimulation computations.

To validate the concept of an electronic system before thinking of commercial uses, a prototype needs to be developed first. However, technical knowledge in electronics and computer science (CS) is required. Due to the importance of these fields in the world of today, where almost everything is regulated by technology, several initiatives emerged to provide the general public with these knowledge. In this context, there is a focus on the education field where several efforts have been made to lower the entry level to electronics and CS fields, enabling even kids to learn the basic concepts at an early age and have the possibility to concretise their ideas and develop their own prototype. The study presents a solution to facilitate the task of programming electronic gadgets using graphicalprogramming. The authors consider as case study an electronic system built around the IOIO board. The graphical programming interface was created using App Inventor, a web platform for creating android apps. Using the proposed system, several basic and complex gadgets were easily created by young school children with minimal skills in hardware assembly and software programming.

This paper introduces Spicedim, a graphical programming interface for integrated CMOS circuit design. It connects the SPICE netlist level to an easy to use programming language, both combined in a graphical development environment. After classifying the context of this tool the fundamental application for parametric circuit simulation and signal processing is shown. This is done at the example of a parameterizable netlist for a current mirror. Further on, Spicedim supports calculations at single MOS-device for a device by device circuit sizing concept. Normally required input parameters for SPICE can be set to be calculated in dependence of specified normally calculated output parameters.
