GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub.

gVirtualXRay is a C++ library to simulate X-ray imaging. It is based on the Beer-Lambert law to compute the absorption of light (i.e. photons) by 3D objects (here polygon meshes). It is implemented on the graphics processing unit (GPU) using the OpenGL Shading Language (GLSL). SimpleGVXR is a smaller library build on the top of gVirtualXRay. It provides wrappers to Python, R, Ruby, Tcl, C#, Java, and GNU Octave.

A collection of applets used to demonstrate physics and math principles. The applets include: a ray diagram drawing applet, a collision of disks applet, an electromagnetic field mapper and a 3d hydrogen orbital simulation.

The Optics Project on the Web (WebTOP) is a 3D, interactive computer graphics system that visualizes optical phenomena. Its purpose is to help instructors teach and students learn about optics. It is a platform independent Java application that uses X3D.

This program allows you to create a transmission hologram using just a computer, a laser-printer, and an overhead transparency. This hologram will behave like one created using a laser and can be projected or viewed with a point source.

This software allows you perform six degree of freedom simulations of High Power Rocket (HPR) and model rocket flights. Parachute descent is also simulated. 3D flight trajectories are produced as well as detailed tabular flight data. Running in Monte Carlo mode allows generates multiple possible flight paths and splash down plots, indicating the probability of landing in an area.

Steam tables for industrial use according to the international standard for the properties of water and steam, the IAPWS-IF97 formulation and the international standards for transport and other properties. Hummeling Engineering BV develops engineering software in the fields of thermodynamics, mechanics, hydrodynamics, and digital signal processing.

This project has the role of simulating simple Curvilinear and Rectilinear Motions with an easy to use user interface. This program can be used for educational purposes as well as for any other purpose anyone would like. The executable file is a .jar files which means that it can run in any operating system that supports java. Above you can see a screenshot of the program while it is operating.

FDTD Antenna Simulator is a complete software package for antenna analysis and design using the FDTD method.

Interactive Web Physics is a Java, Web-based animation and problem designer tool. Anyone can quickly design mathematics or physics animations and simulations that run in a web browser. Unlike other solutions, no knowledge of programming is required.

JCreme is an automated interface to the CREME96 modeling web app (https://creme96.nrl.navy.mil/). It allows the user to send multiple requests to the CREME96 website and retrieve the results. CREME stands for "Cosmic Ray Effects on Micro Electronics"

The Java Astrodynamics Toolkit is a library of components to help users create their own application programs to solve problems in astrodynamics, mission design, spacecraft navigation, guidance and control using Java or Matlab.

An attempt to make a n-body simulator with java

A self-sufficient java framework for numerical solution of ODEs (diff eqs) and visualization. Samples are aeronautics/astronautics/physics/rocketry themed. Focus on clean design, modularity, reusability and documentation. Educational project.

jSGP is a Java implementation of the five SGP/SDP propagators described in NORAD's Spacetrack Report No. 3.

PCP-net is a browser-based application to calculate preheating temperature, heat input and carbon equivalent, which can be used to avoid hydrogen cracking (cold cracking) in unalloyed and low-alloyed ferritic steels.

PUPIL (Program for User Package Interface and Linking), is a software environment that allows developers to link quickly and efficiently together multiple pieces of software in a fully automated multi-scale simulation. More specifically, it supports QM/MM MD simulations where the user might choose among any of the different MD engines and QM engines, which are connected to PUPIL as external programs through a tiny specific interface. One of the main advantages here is that the user can use most of the functionalities that may have those external programs interfaced without the necessity to be reimplemented again on independent interfaces. In fact, this simulation interface concentrates all the common code involved in the coupling terms of the QM/MM approach.

A Java library that works with Java3D to simulate and visualize, in real-time, dynamics of multiple rigid bodies that are restricted by implicit and explicit constraints (e.g., robotics); designed for efficiency, ease-of-use, and extensibility.

Collection of Java Applications related to Scientific World. All these applications have their source code available and can be easily changed by other programmers. Visit http://www.hcroboting.com/ for more information.

This is a recopilation of programs programmed by Eliot Hijano using either Java or Ruby. All the programs have something in common with both physics and Maths and are explained mathematically and physically in its own pdf.

VOpR - A Virtual Optical Rail VOpR allows to create and evaluate simple optical systems, in which the basic optical elements are arranged along the optical axis. The current supported optical elements are: spaces,spherical lenses, circular apertures and flat blocks of some optical medium. The program has three main components: 1. The database editor. Currently the database can store data about: -optical materials, -spherical lenses, -projection properties of light sensors and eyes, -special wavelengths of light and -optical systems as lists of basic optical elements. 2. The editor of linear optical systems. Some properties of the optical system are calculated in real time. 3. The virtual optical rail as a ray-tracing simulation of the optical system. The goal is to provide fast and useful diagnostic images, not realistic blur. Additionally there is full access to the java source code under the terms of the GPLv3.

The Vehicle Maneuver Simulator lets you simulate the maneuvering of simple and complex vehicles with different numbers of wheels, axles and joints.

The Vehicle Simulation Environment consists of a library of Java classes designed to aid in building, propagating, and displaying (in Java3D) vehicle models.
