This research presents the geotechnical zoning map of district 1 in Shiraz municipality with focus on allowable bearing capacity of foundation based on data from 160 boreholes. For this purpose, the mechanical properties are determined according to the results of direct shear, uniaxial, and SPT tests and then safe bearing capacity for strip foundations with widths of 1, 1.5, 2, and 2.5 m, and f...

in order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. in this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. two elements have been added to the lubrication circuit in the modified engine. these elements are hydraulic lifters and an anti-drai...

induction motor bearing is one of the key parts of the machine and its analysis and interpretation are important for fault detection. in the present work vibration signal has been taken for the classification i.e. bearing is healthy (h) or defective (d). for this purpose, clustering based classification of bearing vibration data has been carried out using principal component analysis (pca) and ...

Production of Metallogenic-prognostic map (MPM) was preceded by the preparation of instructions that define three phases of work: preparation (with preparation of the Project), realization of field and laboratory research and data processing with production of different maps and, finally, production of the prognostic map with the accompanying instruction book. During the Project realization, th...

This paper presents the effect of preload on nonlinear dynamic behavior of a rigid rotor supported by two-lobe aerodynamic noncircular journal bearing. A finite element method is employed to solve the Reynolds equation in static and dynamical states and the dynamical equations are solved using Runge-Kutta method. To analyze the behavior of the rotor center in the horizontal and vertical directi...

We develop a new occupancy map that respects the role of the sensor measurement bearing and how it relates to the resolution of the existing occupancy map. We borrow an idea from Konolige for recording and tracking, in an occupancy-like map, the bearing at which sensor readings originate with respect to a given cell. Our specific contribution is in the way we process the sensor pose information...

Bibliometric maps are scaled representations of clusters of papers and provide an overview of a scientific field as provided by those papers and the references between them. We have enhanced our interactive bibliometric explorer (iBEX) to visualise the distribution of phrases over such bibliometric maps. Assuming that generic (non-content-bearing) phrases occur in most of the papers in the map,...

In the parallel map theory, the hippocampus encodes space with 2 mapping systems. The bearing map is constructed primarily in the dentate gyrus from directional cues such as stimulus gradients. The sketch map is constructed within the hippocampus proper from positional cues. The integrated map emerges when data from the bearing and sketch maps are combined. Because the component maps work in pa...

This paper presents a bearing-only SLAM algorithm that generates accurate and consistent maps of large environments by joining a series of small local maps. The local maps are built by least squares optimization with a proper landmark initialization technique. The local maps are then combined to build global map using Iterated Sparse Local Submap Joining Filter (ISLSJF). The accuracy and consis...
