Abstract:

The finite difference (FD) method of monopole source is used to simulate the response of full-wave acoustic-logging in cave formations. The effect of the cave in the formation of borehole full-waves was studied. The results show that the radius of cave is not only linearly related to the first arrival of the compressional wave (P-wave), but also to the energy of the shear wave (S-wave). The converted S (S–S wave) and P-waves (S–P wave) are formed when the S-wave encounters the cave. If the source distance is small, the S–S and S–P waves are not separated, and the attenuation of the S-wave is n

Abstract:

Upon carrying out logging, residues remain in the cutting area. Logging residues are an additional source of wood raw material for the production of fuel chips to be used in bioenergetics. In order to plan the logging residues collection and processing technology, it is necessary to gather information on the amount of this type of waste and its distribution within the cutting area.The article deals with the line intersect (LIS) method.The aim of this article was to assess the accuracy of the LIS method for quantifying logging residues after cut-to-length logging (CTL), uniformly distributed wi

Abstract:

Simulation of the temperature distribution in a brake drum of a commercial truck is carried out using the finite element method. Verification of the predicted values is done using an inertia dynamometer with a data logging system. The effect of variable convective heat-transfer coefficient and the effect of contact area are also studied. From the investigation it is concluded that the present model can be used for the simulation of temperature distribution in rigid brake drums during a fade test.

Abstract:

Abstract Logging costs and profitability are affected by many variables. Computer simulation based on detailed production studies and an accounting-based cost analysis was used to investigate the relative importance of tree size and species group on logging costs and profits. Tree size had the greatest affect on skidding costs. Species group was found to be important only in felling. Marginal tree size and margins for profit and risk were computed for seven timber sales. Marginal tree size ranged from 12+ to 13+ in. Volume in submarginal trees ranged from 16.3 to 44.8% of the total volume. Mar

Abstract:

This work proposes a stochastic process-based inversion to estimate hydrocarbon resistivity based on multifrequency electromagnetic (EM) data. Currently, mesh-based algorithms are used for processing the EM responses which cause high time-consuming and unable to quantify uncertainty. Gaussian process (GP) is utilized as the alternative forward modeling approach to evaluate the EM profiles with uncertainty quantification. For the optimization, gradient descent is used to find the optimum by minimizing its loss function. The prior EM profiles are evaluated using finite element (FE) through compu

Abstract:

RTWT (Real-Time Windows Target) and xPC Target are two developing environments based on Matlab/RTW for hardware-in-loop real-time simulation and rapid control prototype. Some error messages which lead to program stop often occur in their practical applications, such as CPU overload, buffer too small, and so on. In this paper, performance of the two simulation environments were studied by analyzing their working mechanism and conducting a lot of experiments, including signal data logging capability, sampling period and system stability. And the reasons which cause error running messages were an

Abstract:

Efficient and accurate forward modeling of logging tool responses is essential for data inversion in the log data interpretation in both real time and postprocessing. With the aggressive advancement of various high-performance computing techniques and computer hardware technology, it is possible to significantly improve the efficiency of the forward modeling. In this paper, we apply OpenMP to parallelize the simulation of triaxial induction logging tools in 1D multilayered anisotropic formation. The parallel process is explained in detail and numerical examples are presented to demonstrate the

Abstract:

A computer simulation model was developed to represent a logging contractorâ s harvesting and trucking system of wood delivery from the contractorâ s in-woods landing to the receiving mill. The Log Trucking System Simulation model (LTSS) focuses on the impacts to logging contractors as changes in truck turn times cause an imbalance between harvesting and trucking systems. The model was designed to serve as a practical tool that can illustrate the magnitude of cost and productivity changes as the delivery capacity of the contractorâ s trucking system changes. The model was used to perform

New programs in video imagery offer the opportunity to design harvest layouts on a more realistic format, which may al

Abstract:

Electronic Control Unit (ECU) is a crucial component in today’s vehicle. In a complete vehicle, there are many ECUs installed. Each of these controls a single function of the vehicle. During the development cycle of an ECU, its functionality needs to be validated against the requirement specification. The Hardware-in-the-loop (HIL) method is commonly used to do this by testing the ECU in a virtual representation of its controlled system. One crucial part of the HIL testing method is an intermediary component that acts as a bridge between the simulation computer and the ECU under test. This com

Abstract:

The potential gains that could be realized from optimizing timber harvesting are significant. To a great extent it is these initial functions that dictate the quality of future manufacturing steps. Timber harvesting systems are defined by the operations they contain and the equipment that perform them. For any given harvesting situation there are a large number of unique systems, performing under a variety of cost, production, and environmental conditions. The objective of optimized timber harvesting is to reduce cost while simultaneously increasing production and minimizing environmental impa

Abstract:

Due to the volumetric nature of the physics and the measurement, traditional gamma-gamma density tools measure an average bulk density of the formation. However, a bulk measurement is not adequate for certain applications where a more detailed resolution of a radial density profile is necessary. In this paper, a new approach of gamma spectral analysis is introduced focusing on the main Compton scattering angles. Several energy windows are linked to the unique radial layers based on scattering angles and location of interaction. As a result, the density of multiple layers can be calculated. The

Abstract:

Broadband relative dielectric dispersion measurements are considered interesting options for assessment of water-filled pore volume. Conventional models such as Complex Refractive Index Model (CRIM) and Maxwell Garnett (MG), often overlook or oversimplify the complexity of pore structure, geometrical distribution of the constituting fluids, and spatial distribution of minerals. This yields to significant errors in assessment of water saturation especially in rocks with complex pore structure. Therefore, it becomes important to quantify the impacts of pore structure and spatial distribution of
