To prepare for capillary electrophoresis, a spectral calibration with the corresponding matrix standard for the selected group of dyes must be performed on the genetic analyzer in order to accurately detect the dye-labeled primers. Each unknown sample is mixed with the size standard and fo...
To compose a speculative music is first to draw associations with the medieval category of a “musica speculativa”, that esoteric part of music theory that lies beyond the practical and theoretical aspects of musical composition to address existential questions of “why?” 1 It was during this...
Near Infrared (NIR) Spectroscopy is an analytical technique used across a wide range of sectors and industries. Click to read more...
The response and input to such a system is described in a FRF function. Figure 2: Mass-spring-damper single degree of freedom system. In the mass-spring-damper system: m– mass of the system [kg] c– damping of system [Ns/m] k– stiffness [N/m] f– force applied to system [N]...
What is Chemical Reaction Kinetics? Chemical reaction kinetics provide a quantitative or qualitative measurement of the rate(s) of reactions and provide insight into the dependence of these rates on variables such as concentration, temperature, pressure, the presence of catalysts, the physical state of...
If you've ever shopped for speakers or headphones, you've probably come across the term "frequency response" in the product specs. This is one of the key measurements that determines how a speaker or headphone will sound. But what exactly does it mean and why does it matter?
2. Figure 2 shows the quantum efficiency of standard InGaAs in blue together with the quantum efficiencies of two extended wavelength alloys, X=0.74 (green) and X=0.82 (red). The spectral response of silicon is also shown. As we like to say, "InxGa1-xAs starts where silicon leaves off...
To develop and model an optical system for machine vision, the first step is to define the requirements. Often the starting point includes requirements for a specific focal plane to be used in the imaging system, with a certain sensitivity. This has implications on the illumination system, inclu...
Spacer by Spectral Plugins:Spectral Plugins is a manufacturer that unfortunately ceased operations, but upon doing so they made the generous decision to perpetually offer all their plugins for free. Originally $119, Spacer provides advanced capabilities including algorithmic, convolution, and granular reve...
are constructed using three basic main layers: an input layer, a hidden layer and an output layer. The input layer takes in the graph data, which is typically a matrix or a list of matrices. The hidden layer processes the data, and the output layer creates the GNN's output response. ...
