Influences of Wall Angle on Forming Forces in Single-Point Incremental Forming

This study presents experimental results evaluating the influence of wall angle on the forming process of AA5052 aluminum alloy sheets using the incremental sheet forming process. The wall angle investigated varied within the range of 45°-50°-55°-60°, with step-down sizes chosen as 0.5mm and 1.0mm. The forming process was conducted under lubrication conditions, with other parameters

A Comparative Analysis of the Influence of Temperature and Wind Speed on the Efficiency of 100 WP Solar Panels of Monocrystalline and Polycrystalline Types at Sriwijaya State Polytechnic

Solar panels in PLTS convert photon energy into electrical energy, where sunlight, which produces light intensity, plays a very important role. In this case, environmental conditions that continue to change can affect the output power of the solar panels. Apart from light intensity, solar panel environmental conditions such as temperature and wind speed greatly affect

Performance Test of the Molecularly Imprinted Polymer (MIP) Endosulfan Sensor Potentiometrically

Molecularly Imprinted Polymer (MIP) is a synthetic polymer with cavities that are specific for target molecules. Cavities are obtained as a result of template removal, where the function of these cavities is to recognize molecules with the same size, structure and physicochemical properties as them. The polymer produced from the MIP technique is applied to
