Screenshot of a parameter editor in SimSEE.

The Tractorcito is a robot that, using reinforcement learning techniques (trial and error), learns how to operate an electrical power system. This screenshot shows the fitness monitor included in SimSEE.

#SimSEE is an open platform for the #Simulation of Electric Power Systems.

With SimSEE, one can analyse the evolution of e.g., volumes of energy, money exchanged by participants in the market, and risk calculations for contracts.

It is developed in #Object_Pascal with the #Lazarus_IDE.

Figure from the paper: Enhanced Calibration Editor in MEGA 12.1. The Calibration Editor (A) displays an interactive tree of great apes, with several tip names already mapped to NCBI IDs. Scientific names for mapped IDs are shown next to tip names in angle brackets, and applied constraints are shown next to circled nodes. The Quick Help dialog (B) provides brief instructions for defining calibration constraints using either the TimeTree RESTful API or manually. Users can right-click a tip or node in the tree to open the context menu (C) to make TTDB queries for the selected element. The NCBI ID Search dialog (D) is used to map tip names in the tree to NCBI Identifiers used by TTDB. After at least two tip names are mapped to identifiers, time estimates for the MRCA of mapped tip names can be retrieved from TTDB using the Divergence Time Search dialog (E). Calibrations derived from the TimeTree resource can be applied as a uniform density distribution, a minimum time constraint, a maximum time constraint, or a fixed time. A list of studies used for deriving a TTDB time estimate can be retrieved by clicking the Details for studies button.

#MEGA is a global project and widely used software for molecular evolutionary and phylogenetic analyses. Originally developed in C++, it has been ported to #Object_Pascal for cross-platform compatibility on #macOS, #Windows, and #Linux.

This cross-platform RPN calculator has been written in #Object_Pascal with the #Lazarus IDE for the #Free_Pascal compiler. Source code has been made available.

After the first experimental code had been written in #UCSD_Pascal, the majority of #Lisa_OS was written in #Lisa_Pascal. The first versions of #Mac_OS and applications for Lisa OS were written in #Clascal, an early version of #Object_Pascal. The coevolution of #Pascal and Apple OSes is interesting.

Screenshot of the MRIcron user interface on macOS. The main menu provides access to core functions. Users can change the crosshair position by clicking on the image or setting the coordinates in the top toolbar, allowing users to specify the crosshair coordinates (with X, Y, Z referring to the column, row and slice of the image). The title bar reports the crosshair location in world space as well as the voxel intensity. Likewise, users can set contrast and brightness by dragging over the image or using the minimum and maximum thresholds in the titlebar. A pull-down menu allows the user to select the color scheme (here Grayscale). Buttons in the toolbar allow the user to display a gradient colorbar and draw lesions. The bottom status bar reports recent changes (here the new contrast values).

Demo image. MRIcron introduced improved drawing tools to map lesions on individual participants (inset on right, sub-09) and create lesion incidence maps. The multicolored incidence map overlay shows the fractional incidence (thresholded for blue at 1% and red at 10%) for 1449 individuals. Both images from the Stroke Outcome Optimization Project (SOOP)

MRIcron, a powerful visualisation tool for neuroimaging research, has been written in #Object_Pascal with the #Lazarus_IDE to support platform-sensitive development and to provide a processor-native high-performance software system.

Figure: Benchmarking results of code generated in five different programming languages (S/R, Python, Swift, C++ and Object Pascal) for simulation of two different types of feedback control systems. Object Pascal generates the by far fastest code.

For a completely different task, simulating biological feedback loops, #Object_Pascal generates the fastest code. It is not only faster than that of interpreted languages (S/R and Python) but even outperforms fast compiled languages (C++ and Swift).
