Novel technique for enhanced visual recognition of the landform features developed by spatial analysis on the digital terrain model (DTM) is proposed. The approach called “visibility simulation technique” is consisted form the following steps: (1) visibility calculation, (2) altering an azimuth and zenith angle (following the proposed algorithm), (3) generating continuous surfaces that indicate...

1 Abstract In this paper a procedure for global optimisation is presented. The procedure combines on two methods, viz. the Multipoint Approximation based on Response Surface fitting (MARS) Method and a global optimisation method. The MARS method is based on the approximation concepts according to which the original minimization problem is replaced with a succession of simpler ones formulated fo...

Path planning is one of the most vital elements of mobile robotics, providing the agent with a collision-free route through the workspace. The global path plan can be calculated with a variety of informed search algorithms, most notably the A* search method, guaranteed to deliver a complete and optimal solution that minimizes the path cost. D* is widely used for its dynamic replanning capabilit...

In this paper, we discuss the development of an Interior Point Method (IPM) solver for Second Order Cone Programming optimization problems that is capable of producing customized ANSI-C code for embedded, real-time applications. The customized code is generated for a given problem structure and makes use of no dynamic memory allocation, minimizes branching, wastes no mathematical or logical com...

The problem of precision landing on Mars is now considered to be an essential challenge in the planned Mars missions. The paper focused on the guided atmospheric entry as a predominant phase in achieving a desired target state, as compared with the following parachute and powered descent. The predictive algorithms for the longitudinal guidance of a low-lift entry vehicle are treated. The purpos...

We present the first systematic study of clouds observed during twilight on Mars. analyze images obtained by Visual Monitoring Camera Mars Express between 2007 and 2020. Using an automated retrieval algorithm, we found 407 cases at twilight, in which geometry observations allows to derive minimum altitude, revealing that many these are mesosphere (above 40 km up 90 km). The majority mesospheric...

coalbed methane (cbm) plays an important role in coal mining safety and natural gas production. in this work, the cbm potential of b2 seam in parvadeh iv coal deposit, in central iran, was evaluated using a combination of local regression and geostatistical methods. as there were 30 sparse methane sampling points in the parvadeh iv coal deposit, no valid variogram was achieved for the methane c...

The continental margin off northeast Australia, comprising the Great Barrier Reef (GBR) platform and Queensland Trough, is the largest tropical mixed siliciclastic /carbonate depositional system in existence. We describe a suite of 35 piston cores and two Ocean Drilling Program (ODP) sites from a 130 × 240 km rectangular area of the Queensland Trough, the slope and basin setting east of the cen...
