The proposed software framework is presented and an Application Programming Interface (API) is developed based on the Arduino Mega 2560. The API processes external commands that follow the operational logic of a gel electrophoresis device. The API acts as an intermediary layer between the gel electrophoresis mechatronic system’s microcontroller and the motors’ controllers. The microcontroller enables the basic functionalities of the gel electrophoresis system while the use of 2 axis (X, Z) motor controllers is necessary for controlling the moving parts of the mechatronic system. We control the movement’s direction, position, speed, and acceleration. The developed API controls the stepper motors drive axles and the DC motors for opening and closing the drawers and other moving parts of the mechatronic system.

The paper present the methodology to design and implement a mechatronic system for gel electrophoresis. It describes the steps towards the development of a prototype and presents its functions. The new automated system is characterized by high precision, small size and relatively low cost, thus achieving the introduction of a significant innovation in the area of medical and laboratory measurements.

Laser melting and re-solidification has been used to densify and homogenize ceramic surfaces, leading to increased high-temperature corrosion and erosion resistance. Although complete sealing of pores can be achieved on the surface, pores have been observed in the boundary between the laser-treated zone and the untreated bulk. This paper investigates the mechanisms of pore formation and the various factors affecting it. A simple analytical model that predicts the maximum final pore diameter and location along the treated zone/untreated bulk boundary is derived, in terms of the materials properties and the processing parameters. Experimental investigations for a range of processing speeds and power densities have verified the model predictions, identifying the effects of processing speed and laser power density on the maximum pore diameter.
