Controlling Microfluidic Cell Cultures

Ongoing
Intended impact:Cell behavior is powerfully modulated by local extracellular cues. However, the number of parameters that affect cell behavior is large, and include soluble signaling molecules, dissolved gases, the chemistry and mechanics of the extracellular matrix, and the proximity and behavior

Cooperative Diversity Routing and Transmission for Wireless Sensor Networks

Completed
In order to address the challenges of cooperation, PHY layer cooperation schemes were proposed and, to a limited extent, medium access control (MAC) layer schemes. On the network layer, the network coding techniques can be viewed as a form of cooperation as well. To the best of our knowledge, there

Cooperative vs Non-Cooperative Diversity in Space, Time and Frequency

Completed
Broadband communication plays an increasingly important role in meeting the growing demand for high-speed multimedia transmissions in our daily lives. However, when the bandwidth of a signal exceeds the coherent bandwidth of the wireless channel, the small-scale fading imposed on the signal becomes

Cooperative Single-Carrier FDMA Communications

Completed
The worldwide growth in both the number of mobile subscribers and their demand for increased rate mobile broadband services provided further impetus for the mobile telecommunication operators to improve both the capacity and the reliability of cellular networks. When communicating over broadband

Core Network Technologies

Ongoing
The technologies underlying all aspects of modern networks are undergoing rapid and fundamental changes. Disruptive innovation and exponential growth in network scale and complexity will require new approaches to network design, deployment, and operation. Examples of disruptive innovation include

5G/6G Core Networks and Services

Ongoing
The main tasks of this program are: Task 1: 6G Core Network Architecture: I nvestigating AI-native architectures that not just execute AI/ML-based network functions but also support the creation, management, cooperation, measurement, and evolution of these functions. Task 2: Key Technologies Task 2

5G Core Networks Testbed

Ongoing
This project, as part of our 6G Core and Edge Networks and Services Project, is building a 5G/6G Core Network Testbed— which we refer to as OpenCoreNet—to support research on sixth generation (6G) networks and to explore how 6G can best improve industry applications. OpenCoreNet focuses on core

Coriolis Mass Flow Meters as Field Test Standards

Ongoing
Customers and businesses alike rely on metering systems to monitor and deliver their liquid-based commercial products (including a range of gas and fuels) consistently over time and across a range of locations. Weights and measures officials use several well-acknowledged field test standards to

COVID-19 Spectrum Occupancy Project

Ongoing
Collected from residential teleworking sites, hospitals, and public safety networks across the Colorado Front Range, the data will help CTL understand trends in spectrum usage during national emergencies. Gathered data will also work towards investment in the broader development of an infrastructure

Critical Current Metrology

Ongoing
PML staff have completed the construction and testing of a variable-temperature and variable-strain, or unified, apparatus for measuring critical current. The apparatus combines world class capabilities in variable-temperature and variable-strain measurements and is expected to be the highest

Cruciform Multiaxial Mechanical Testing

Ongoing
A new ARRA funded cruciform test machine is being installed in the NIST Center for Automotive Lightweighting. Its capabilities include 500kN load per axis, two DIC strain mapping systems (one for large field mapping and one for zooming in to study localizations or features), a high resolution, high

Cryogenic Photonic Interconnects

Ongoing
Microwave photonics, where optical systems are employed to transport, filter, generate, or otherwise process microwave and millimeter wave signals, takes advantage of the large bandwidth, low loss, and low noise of optical systems, as well as the long reach of optical fiber interconnects. We are

Cryogenics

Ongoing
Almost all the devices developed by the Quantum Sensors Group work at temperatures below liquid helium. Sometimes, it is necessary to develop specialized cryogenics to test the devices, or to facilitate their dissemination to outside users. The cryogenics team also aims to make refrigerators more

Crystal Plasticity Modeling of Yield Surface Evolution

A robust multiaxial constitutive law is needed to predict stresses within parts formed from sheet metal to be able to compensate for such phenomena as elastic springback. Ideally, the constitutive law would not need to be "trained" using empirical mechanical property data alone, but would be able to

Crystallographic Databases

Ongoing
Impact and Customers Materials with new or improved properties are continually being developed to meet demands for increased functionality of components and devices at decreased costs. Examples of multi-million dollar industries driven by materials advances are solid-state lighting (GaN-based

Cyber Physical Systems and Internet of Things Program

Ongoing
Objective - Enable scalable, dependable design methods and reproducible performance measurement for effective and trustworthy (reliable, safe, secure, resilient and privacy-enhancing) cyber-physical systems and IoT, by means of new measurement science, advanced testing and assurance capabilities and

Cyber-Physical Systems/Internet of Things for Smart Cities

Ongoing
Objective - To provide the measurement science and standards-based foundations for interoperable, replicable, scalable, and trustworthy cyber-physical systems that can be readily and cost-effectively deployed by cities and communities of all types and sizes to improve their efficiency

Cyber-Physical Systems/Internet of Things Testbed

Ongoing
Objective - To develop general design principles useful to all cyber-physical systems testbed developers and the co-simulation community; to develop specific design concepts to guide the development, operation, and evolution of NIST’s IoT/CPS testbed; and to establish a cross-sector IoT/CPS testbed
