Adaptive impedance controller for prosthetic hand object grasping and manipulation
(Wichita State University, 2021-05)There are many complexities involving the human hand’s ability to perform stable grasping patterns. Human grasping is a complicated function to mimic in relation to prosthetic hands. Although there are various state-of-t ... -
Adaptive rate control algorithm to improve the performance of H.264 video codec in varying network conditions
(2006-12)This thesis involves proposing an efficient algorithm, which takes into consideration the NALU (Network abstraction Layer Unit) and tries to improve the H.264 codec performance over a network. Along with the bandwidth ... -
Additive manufacturing of functionally-graded copper/aluminum wick structures by hot-pressing for enhanced thermal performance
(Wichita State University, 2022-05)Two-phase passive cooling systems such as heat pipes and vapor chambers (also known as flat heat pipes) are widely used for its reliable high heat flux cooling capacity and its ability to transfer heat over large distances ... -
Adhesiveless honeycomb sandwich structure with carbon graphite prepreg for primary structural application: a comparative study to the use of adhesive film
(Wichita State University, 2012-05)In the past two decades, researchers have been developing prepreg materials with matrix properties that can allow the elimination of the additional adhesive traditionally used between the core and the skins of composite ... -
Adsorption and capillary transition-controlled thermal diodes and switches using heterogeneous nanostructures
(Wichita State University, 2017-12)Thermal diodes and switches are systems that enable us to control thermal transport, preferentially in one direction, and switch "on"/"off" on demand. The main challenges of existing thermal diodes and switches are poor ... -
Advanced failure diagnostics and prognostics for complex system health management
(Wichita State University, 2014-05)This dissertation consists of four published or accepted journal articles that address some of the key problems in prognostics and health management area (PHM). Effective health diagnostics and prognostics provide multifarious ... -
