In this study, head injury criteria (HIC) and chest severity index (CSI) assessments are made based on finite element simulation. Simulations are carried out through nonlinear finite element analysis software LS-Dyna. The effect on the occupant’s injury of introducing aluminum alloy, AA5182, to automotive side members is highlighted in comparison to the existing model made of steel. The HIC and...

Coherent communication over fading wireless channels requires channel state information (CSI). Therefore, CSI has value. Communication systems that require CSI must devote some system resources to obtaining it. CSI has associated cost. When the cost can be used to train either the transmitter or the receiver, then the optimal solution is to allocate the training where it will have the highest v...

This study sought to establish the psychometric properties of a Coping Strategies Inventory Short Form (CSISF) by examining coping skills in the Jackson Heart Study cohort. We used exploratory and confirmatory factor analysis, Pearson's correlation, and Cronbach Alpha to examine reliability and validity in the CSI-SF that solicited responses from 5302 African American men and women between the ...

Background Although chemotherapy is used routinely in pediatric medulloblastoma (MB) patients, its benefit for adult MB is unclear. We evaluated the survival impact of adjuvant chemotherapy in adult MB. Methods Using the National Cancer Data Base, we identified patients aged 18 years and older who were diagnosed with MB in 2004-2012 and underwent surgical resection and adjuvant craniospinal i...

We consider wideband wireless communication over a multiple-input, multiple-output (MIMO) Rayleigh fading channel where the transmitter has no channel state information (CSI). We study the channel with perfect receiver CSI (coherent channel) versus the channel with no CSI at the receiver (non-coherent channel). A channel with partial CSI at the receiver has a capacity between the coherent and n...

PURPOSE Anesthesiologists are often involved in the early management and resuscitation of patients who have sustained cervical spine injuries (CSIs). The most crucial step in managing a patient with suspected CSI is the prevention of further insult to the cervical spine (C-spine). In this review, important factors related to initial management, diagnosis, airway and anesthetic management of pat...

The Complex Streamed Instruction (CSI) set is an ISA extension targeted at multimedia applications. CSI instructions process two-dimensional data streams stored in memory, performing sectioning, data alignment and conversion between different packed data types all in hardware. It has been shown previously that CSI provides significant speedups compared to current media ISA extensions such as MM...

In the paper, we propose a channel-state-information (CSI) feedback method, especially, for large-scale MIMO (LMIMO) systems. From the enormous CSI, to extract essential information without redundant information, which arises from the highly correlated antennas, and to make the CSI to be sparse with its essential information, we propose to use a primary component analysis using a Karhunen-Loève...

In-space fljght experiments are required to validate dynamic response and control characteristics of ground experiments and their models in order to support future DoD/NASA Large Precision Space Structures missions. This paper, based on an ongoing Small Business Innovation Research(SBIR) Program with the Air Force Astronautics Laboratory, will describe an innovative approach for space flight ex...
