This article proposes a new planning navigation strategy for use with mobile terrestrial robots. The proposed algorithm is applicable in any point of the areas for tasks such as cleaning the floors of building, mowing and clearing mined areas. The strategy of this algorithm is analyzed and checked in conditions where the environment and the obstacles are known. There are various routing algorit...

this study focused on the optimization of al—mg to cuzn34 friction stir lap welding (fslw) process for optimal combination of rotational and traverse speeds in order to yield favorable fracture load using grey relational analysis (gra). first, the degree of freedom was calculated for the system. then, the experiments based on the target values and number of considered levels, corresponding orth...

Dalam memproduksikan minyak sangat penting dalam menghitung laju alir maksimal dan optimum. Oleh karena itu perlu dilakukannya analisis sistem nodal. Analisis nodal adalah penggabungan antara Kurva IPR dengan Outflow, dimana akan didapat optimum sumur tersebut. merupakan metode yang dapat digunakan untuk memperbaiki kinerja sumur. Prosedur menentukan kehilangan tekanan korelasi Hagedorn & B...

The widespread application of thermoplastic polymers in different aspects of industries has motivated researchers and companies to improve and upgrade their forming, joining and assembling processes to overcome their limitations. One of the newest joining methods of thermoplastics is friction stir welding which is based on frictional heat generated through contact between a rotating tool and th...

Traversing is a fundamental operation in surveying and the assessment of the quality of a traverse is a skill that every surveyor develops. Acceptable traverses have angular and linear misclosures that fall within acceptable bounds; which would permit the adjustment of the traverse measurements to remove mathematical inconsistencies. Unfortunately these misclosures tell very little about the pr...

Soft x rays are generated when low-energy electron beams traverse a solid-state superlattice. We investigate the influence of x-ray absorption and electron scattering losses on the maximum power radiated, the required electron energy, and the optimum total thickness of the superlattice. We show that a moderate increase in the electron-beam energy compensates for the losses due to photoabsorptio...
