Using a high-value resistor in triangle comparisons of electrical standards

IEEE Transactions on Instrumentation and Measurement, 2003
We propose an experiment with some advantages over other direct quantum metrology triangle comparisons. First, by using a cryogenic resistor that can be calibrated, the quantized Hall resistance (QHR) standard needs to be used only for short periods. Second, the experiment does not require a voltage detector.

A standard target for triangles or how to transfer TOD to MTDP

Electro-Optical and Infrared Systems: Technology and Applications XVIII and Electro-Optical Remote Sensing XV, 2021
Triangle Orientation Discrimination (TOD) developed by TNO Human Factors and Minimum Temperature Difference Perceived (MTDP) developed by Fraunhofer IOSB are competitive measurement methods for the assessment of well and under sampled thermal imagers.

Unitarity Triangle Analysis beyond the Standard Model

AIP Conference Proceedings, 2005
Starting from a (New Physics free) tree level determination of ρ and η, we perform the Unitarity Triangle analysis in a general extension of the Standard Model with arbitrary new physics contributions to loop‐mediated processes. Using a simple parametrization, we determine the allowed ranges of non‐standard contributions to ΔF = 2 processes.

Standardization of Bone Mineral Density at Femoral Neck, Trochanter and Ward's Triangle

Osteoporosis International, 2001
The International Committee for Standards in Bone Measurement (ICSBM) has published standardization formulas for total hip bone mineral density (BMD). In many applications, however, BMD of hip subregions, such as femoral neck (FN), trochanter (TR), and Ward's triangle (WT), are commonly measured.

2D Image to Standard Triangle Language (STL) 3D Image Conversion

2021
Nowadays, the use of 3D printing has extensively increased, which support STereoLithography or Standard Tessellation Language (STL) 3D image for printing. STL file originated from the 3D systems. STL file format works over the triangles and estimates the surfaces of a solid model without any texture and color. It specifies both binary and ASCII formats.

Triple Standard: Addressing the Missing Middle in the Texas Triangle

Open, 2020
There’s an urban phenomenon happening in Texas. It’s called the Texas Triangle. Dallas-Fort Worth defines the top while Austin-San Antonio and Houston create the base. These major urban areas are connected by Interstate-45, Interstate 10, and Interstate 35. These cities, and other smaller ones, are experiencing significant transformational growth. Much

Testing Standard Model and New Physics with the Unitarity Triangle Fit

AIP Conference Proceedings, 2006
Starting from a (New Physics free) tree level determination of ρ and η, we perform the Unitarity Triangle analysis in a general extension of the Standard Model with arbitrary new physics contributions to loop‐mediated processes. Using a simple parameterization, we determine the allowed ranges of non‐standard contributions to ΔF = 2 processes.
