In this paper, a numerical efficient method based on two-dimensional block-pulse functions (BPFs) is proposed to approximate a solution of the two-dimensional linear stochastic Volterra-Fredholm integral equation. Finally the accuracy of this method will be shown by an example.

Inductive proximity sensors (IPSs) present a unique no-contact advantage. They are widely preferred for displacement measurement in various industrial fields (e.g., aviation and aerospace), and they are improved continuously. When the inductance and resistance components of the IPS sensing core are separated, the influence of temperature drift on measurement can be eliminated. The complexity of...

The scope of this review is to investigate the main post-process optical form measurement technologies available in industry today and to determine whether they are applicable to industrial-grade metal additive manufactured parts. An in-depth review of the operation of optical three-dimensional form measurement technologies applicable to metal additive manufacturing is presented, with a focus o...

Investment casting is a versatile manufacturing process to produce high quality parts with high dimensional accuracy. The process begins with the manufacture of wax patterns. The dimensional accuracy of the model affects the quality of the finished part. The present study investigated the control and optimization of dimensional deviations in wax patterns. A mold for an H-shaped wax pattern was ...

One of the most promising technique for temperature measurement is the Laser Induced Fluorescence (LIF) which utilize basic concept of optical, non-intrusive measurements and give possibility to visualize the temperature distribution in the whole two-dimensional plane at once. A major problem of a LIF is it still unsatisfactory accuracy for temperature gradient and heat transfer measurement. Th...

Unbaked earth structures, like adobe structures are found in abundance throughout the world. Like most structures, they are subject to deterioration through time. The preservation of historic adobe structures requires careful attention and evaluation of several factors, but material erosion is the main concern. In order to calculate the amount of erosion, accurate measurement of the structures ...
