Sensitivity analysis of factors influencing the head injury criteria evaluation using computational simulations with a free-motion headform model
(Wichita State University, 2019-05)In aviation and automotive crash scenarios, head injuries are the most severe and fatal type among all the injuries incurred to the occupants. Head injuries typically occur when the head of the occupant comes in to contact ... -
Sensitivity and uncertainty analyses of ex-vessel molten core cooling in a flooded cavity during a severe accident
(Elsevier Ltd., 2018-03)Sensitivity and uncertainty analyses of molten core cooling under the ex-vessel phase of a severe accident of a light water reactor was performed with the COOLAP-I (COOLability Analysis Program-I) model, a parametric model ... -
Sensitivity-based, multi-objective design of vehicle suspension systems
(ASME, 2015-05)This article deals with the dynamic response optimization of mechanical systems, based on the computation of independent state sensitivities. Specifically, the dynamic behavior of a coach is analyzed in detail so as to ... -
Sensor fusion of structural finite element model with inertial sensor data to measure wing deflection of a fixed wing aircraft
(American Institute of Aeronautics and Astronautics Inc, 2020-01-05)This research is a continuation of prior experimental work describing the application of sensor fusion to obtain structural wing deflection data with acceptable accuracy. A Kalman filter design is described introducing a ... -
A sequential Bayesian cumulative conformance control chart for high yield processes
(Wichita State University, 2009-05)For mass production, the traditional approach of drawing the confidence limits was satisfactory when many bad units were being produced; however, the same approach becomes ineffective for high yield processes, when the ... -
A sequential Bayesian Cumulative Conformance Count approach to deterioration detection in high yield processes
(John Wiley and Sons, 2012-03)Cumulative conformance count (CCC) control chart is a powerful alternative to the traditional p-control chart, particularly in monitoring high yield processes with extremely low proportions of nonconformance. However, a ... -
Sequential low-thrust orbit-raising of all-electric satellites
(MDPI Multidisciplinary Digital Publishing Institute, 2020-06-04)In this paper, we consider a recently developed formulation of the electric orbit-raising problem that utilizes a novel dynamic model and a sequence of optimal control sub-problems to yield fast and robust computations of ... -
Service differentiation mechanism via cooperative medium access control protocol
(Springer, 2006)Providing differentiated Quality of Service (QoS) levels is an important challenge for wireless ad hoc networks and wireless LANs when applications have diverse performance requirements. The IEEE 802.11e MAC protocol can ... -
Service differentiation via cooperative MAC protocol (SD-MAC)
(2005-12)With the recent advances in wireless communications and networking area, it has been a great challenge for researchers to improve a medium access protocol for providing an efficient service differentiation in wireless ad ... -
Setup approval and self starting schemes for short production runs
(2005-12)A number of approaches have been proposed for applying statistical process control in short production runs. However little has been done to provide a methodology to compare and select from various statistical process ... -
Shapley value-based satellite communication bandwidth allocation strategy
(Wichita State University, 2021-04-02)Satellite technology is essential in the field of communications and is popularly called SATCOM, short for Satellite Communication. Bandwidth and connectivity needs are the two main expensive resources in SATCOM that are ... -
Shared entry logger to eliminate duplicate requests to SDN controller
(IEEE, 2019-03-14)In network architecture domain, software-defined networking (SDN) provides programmable network infrastructure and improves management at the controlling layer level. However, SDN structure is centralized and hence introduces ... -
