Adaptive-critic based neural networks for aircraft optimal control

Abstract: A dual neural network architecture for the solution of aircraft control problems is presented. The neural network structure, consisting of an action network and a critic network, is used to approximately solve the dynamic programming equations associated with optimal control with a high degree of accuracy. Numerical results from applying this methodology to optimally control the longitudinal dynamics of an aircraft are presented. The novelty in this synthesis of the optimal controller network is that it needs no external training inputs; it needs no a priori knowledge of the form of control. Numerical experiments with neural-network-based control as well as other pointwise optimal control techniques are presented. These results show that this network architecture yields optimal control over the entire range of training. In other words, the neural network can function as an autopilot. A scalar problem is also used in this study for easier illustration of the solution development.

Thermophysical Properties of ZrB2 and ZrB2–SiC Ceramics

Abstract: Thermophysical properties were investigated for zirconium diboride (ZrB2) and ZrB2–30 vol% silicon carbide (SiC) ceramics. Thermal conductivities were calculated from measured thermal diffusivities, heat capacities, and densities. The thermal conductivity of ZrB2 increased from 56 W (m K)−1 at room temperature to 67 W (m K)−1 at 1675 K, whereas the thermal conductivity of ZrB2–SiC decreased from 62 to 56 W (m K)−1 over the same temperature range. Electron and phonon contributions to thermal conductivity were determined using electrical resistivity measurements and were used, along with grain size models, to explain the observed trends. The results are compared with previously reported thermal conductivities for ZrB2 and ZrB2–SiC.

Methods for the determination of binding constants by capillary electrophoresis

Abstract: Apparent equilibrium constants for molecular association (e.g., association constants, binding constants, dissociation constants, partition coefficients) can be determined with a variety of different capillary electrophoresis (CE) approaches. In many cases, the investigated association behavior is between a smaller molecule or ion (i.e., the solute, drug, or analyte of interest) and a larger entity (e.g., proteins, micelles, polymers, chiral selectors such as cyclodextrins, etc.). Each experimental approach has advantages and disadvantages. Frequently, it is the nature of the system being evaluated that determines the optimal experimental approach. Six different CE-based techniques for evaluating binding constants are reviewed. Examples of each method, and recent references on its use are given.

Aerospace applications of laser additive manufacturing

Abstract: Additive manufacturing (AM) has been used in aerospace applications from the beginning. It not only plays a role as a rapid prototyping technology for saving capital and time during the product development period but also brings profound influences on product design, direct part fabrication, assembly, and repair in the aerospace industry. Because of recent developments, AM has rapidly become a strategic technology that will generate revenues throughout the aerospace supply chain. In this chapter, we analyze the characteristics of aerospace components favoring AM, discuss different aerospace applications benefit from different AM processes, and describe the repair applications for aerospace components. Examples of aerospace applications both from commercial and academia areas are also analyzed. Finally, this chapter discusses the challenges of applying AM to the aerospace industry and potential future aerospace applications.

Organizational change

Abstract: It has also been suggested that I only include information related to organizational change as it relates to for-profit organizations. When I suggest that there is also relevant information which relates to social change, typically, I hear the recommendation that I should focus on one or the other but not both. This appears to be a secondary manifestation of a belief that the dynamic of organizational change is directly linked to methodology. As of yet, I have not heard a credible argument as to how the dynamic of social change differs from corporate change. The main differences appear to be related to the goals of the desired change. Even suggesting a correlation between corporate and social change appears to challenge widely and, apparently, deeply held assumptions about the nature of organizational change.
