Grafik Penentuan Komposisi Campuran Agregat Material Pengaspalan Jalan Memanfaatkan Metode Digital Differential Analyzer (DDA)

The more advanced technology can make it easier for someone to do their work. Included in it in terms of making graphics that can be done using computer assistance. Where computers can represent human work functions. This study aims to create an application graph for the determination of the composition of the aggregate mixture and provide the results of the calculation of the percentage of each aggregate and provide recommendations whether the composition of the aggregate mixture is feasible or not to be used. The results of this study are a graphical application for determining the value of the composition of the aggregate mixture. This application has been tested using DOSBox and TURBO C ++. Based on the results of these trials it can be concluded that the application of graphs to determine the value of aggregate mixture composition can be used as a tool for making graphs of aggregate mixtures and determining the value of aggregate composition and providing recommendations in the form of recommendations.

Programming Men and Machines. Changing Organisation in the Artillery Computations at Aberdeen Proving Ground (1916-1946)

After the First World War mathematics and the organisation of ballistic computations at Aberdeen Proving Ground changed considerably. This was the basis for the development of a number of computing aids that were constructed and used during the years 1920 to 1950. This article looks how the computational organisation forms and changes the instruments of calculation. After the differential analyzer relay-based machines were built by Bell Labs and, finally, the ENIAC, one of the first electronic computers, was built, to satisfy the need for computational power in ballistics during the second World War.

Control System Design and Trajectory Planning for SCARA Robots

Based on STM32F407ZET6 microprocessor with ARM Cortex-M4 core, we designed a controller for servo motors and servo drivers of a 4-axis Selective Compliance Assembly Robot Arm (SCARA) robot. The forward and inverse kinematic equations are established, circular interpolation equations in three-dimensional space are derived by using the digital differential analyzer method. The adopted circular interpolation algorithm avoids to judge quadrant and feeding direction, which simplifies the program.

A Comparison of Standard One-Step DDA Circular Interpolators with a New Cheap Two-Step Algorithm

We present and study existing digital differential analyzer (DDA) algorithms for circle generation, including an improved two-step DDA algorithm which can be implemented solely in terms of elementary shifts, addition, and subtraction.
