This paper presents an experimental and analytical assessment of the performance of steel beam-column assemblies with two types of moment-resisting connections...
This paper describes a service-oriented sensor data interoperability architecture for Institute of Electrical and Electronics Engineers (IEEE) 1451 smart...
A standard methodology exists for estimating the flux from front projection displays by sampling the projected illuminance of a white source signal. With the...
Several theories exist concerning the chip formation process. These theories are used in metal cutting modeling, which is a useful tool to better understand the...
The measurement of small-area black regions on a white screen (such as a character stroke) can be subject to large errors because of veiling glare in the...

Recent work has shown that the negative bias temperature instability (NBTI) can be significantly suppressed through the incorporation of fluorine in the gate...
Murugan Ramalingam, Marian F. Young, Vinoy Thomas, Carl Simon Jr.
Statement of Purpose: We are developing combinatorial methods for screening cell-material interactions. Although previous approaches for rapid screening have...
The environmental impact of product manufacturing, use, and disposal has become a worldwide concern. Laws and regulations designed to protect human health and...

Statement of Purpose: With few successful products in the market despite large investments in tissue engineering research, there is a need to accelerate tissue...
This paper suggests that evolutionary models of network infrastructure in market economy can be derived from the underlying selfish behavior of users and...
For mechanotransduction studies, extracellular matrix proteins should be robustly attached to the surface to prevent cell delamination during deformation. The...
The EtherNet/IP interoperability recommendations are a result of work generated by the ongoing series of EtherNet/IP Implementors Workshops. The recommendations...
