Mine development requires continuous management because it causes rapid topographic changes and environmental damage. Drones can be used to produce three-dimensional spatial information by quickly accurately photographing areas that are difficult or dangerous for humans approach. In this study, we investigated the possibility of using drone photogrammetry determining recovery in mines. The accu...

Purpose: Analysis of the problem choosing optimal set machines in building transport construction facilities. The equipment rational combination choice earthmoving sets is always relevant. Construction process productivity, time, labor costs, production costs and many other indicators efficiency depend on how rationally chosen machine sets. Methods: calculation formulas reliability theory, theo...

in this paper, a new enhanced version of the particle swarm optimization (pso) is presented. an important modification is made by adding probabilistic functions into pso, and it is named probabilistic particle swarm optimization (ppso). since the variation of the velocity of particles in pso constitutes its search engine, it should provide two phases of optimization process which are: explorati...

often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. instead it is obtained by some numerical analysis such as fe structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...

this paper proposes a method to solve multi-objective problems using improved particle swarm optimization. we propose leader particles which guide other particles inside the problem domain. two techniques are suggested for selection and deletion of such particles to improve the optimal solutions. the first one is based on the mean of the m optimal particles and the second one is based on appoin...

In Pakistan, many subsurface (SS) drainage projects were launched by the Salinity Control and Reclamation Project (SCARP) to deal with twin problems (waterlogging salinity). some cases, sump pumps installed for disposal of SS effluent into surface channels. Presently, have become dysfunctional due social financial constraints. This study evaluates alternate design Paharang system that could per...
