Raman analysis has been found to provide otherwise hard obtain information on inverse vulcanised polymers, including their homogeneity, sulfur rank, and unpolymerised content.

In this paper, we consider some statistical aspects of inverse problems. using Bayesian analysis, particularly estimation and hypothesis-testing questions for parameterdependent differential equations. We relate Bayesian maximum likelihood Io Tikhonw regularization. and we apply the expectatian-minimization (F-M) algorithm to the problem of setting regularization levels. Further, we compare Bay...

Abstract. Recent inverse solutions obtained from some geoscience applications are presented. The estimation of the vertical atmospheric temperature from radiaces at infrared wavelenth is computed employing artificial neural networks, where good retrievals are obtained. A source-repector strategy is used for identifying the atmospheric pollutant source, where the Lagrangian particle model is app...

Modern area preserving projections employed by cartographers and geographers have closed forms when transitioning between the sphere and the plane. Inversions from the planar map to the spherical approximation of the Earth are slower, requiring iterative root finding approaches or entirely undetermined. Recent optimizations of the common Inverse Snyder Equal Area Polyhedral projection have been...

Human motion is accomplished through muscle actuation producing torque about each joint. Inverse dynamics allows for the measurement of these forces and torques to be determined with non-invasive data collection techniques at low cost. Video was processed using MATLAB to determine position data of markers on each joint throughout a given motion. Position data was then converted into a series of...

We consider an inverse scattering problem for multiple obstacles D = ⋃N j=1 Dj ⊂ R with different types of boundary for Dj . By constructing an indicator function from the far-field pattern of the scattered wave, we can firstly reconstruct the shape of all obstacles, then identify the type of boundary for each obstacle, as well as the boundary impedance in the case that obstacles have the Robin...

Inverse kinematics solutions for multi-DOF arms can be classified as analytical or numerical. In general, analytical solutions are preferable to numerical solutions because analytical ones yield complete solutions and are computationally fast and reliable. However, analytical closed-form solutions for inverse kinematics of 6-DOF arms rarely exist for real-time control purpose of fast moving arm...

Inverse Transient Analysis (ITA) is a powerful approach for leak detection of pipelines. When the pipe transient flow is analyzed in frequency domain the ITA is called Inverse Frequency Response Analysis (IFRA). To implement an IFRA for leak detection, a transient state is initiated in the pipe by fast closure of the downstream end valve. Then, the pressure time history at the valve location is...
