Opis:: This article deals with the analysis of the fractal dimension of streamers propagating in mineral oil, under lightning impulse voltage, using the box counting method; the method and technique of calculation are described therein. In the considered experimental conditions, the average velocities of recorded streamers are of 2.4 km/s and 1.8 km/s for positive and negative streamers, respectively; these velocities correspond to the 2nd mode of streamers propagation. It is shown that the streamers present the fractal dimension D ; and the higher D is the bushier are the streamers (i.e. with high branch density). The positive streamers can have higher D than the negative ones, if they are bushier.

Opis:: Due to the remoteness and harshness of some environments, integrating mobile robotics and seismic surveying to automate the process becomes very attractive. Because robotic applications to seismic surveying have been extremely limited, this paper represents a base for sparking novel techniques that can potentially be employed in any environment and potentially on other planets. It also presents a categorization of techniques involving robotic seismic automation. Traditional seismic methods are analyzed in terms of robotic automation possibilities and compared in terms of strengths, weaknesses, reliability, relative cost, and complexity. Futuristic seismic methods such as Hybrid Streamers and a Multi-Robot Seismic Surveying Team are also discussed in detail, along with simulation results from a multi-robot grid formation study.
