Digital resolution

Digital authentication is a new method recently used to detect art forgeries. A high resolution digital scan is made of an artwork under scrutiny. Then a statistical model of an artist is built up from scans of the artist s authentic works. A comparison is made between...

The emf of a cell is best determined by measurements with a potentiometer, since this method gives a very close approach to reversible operation of the cell. The cell potential is opposed by a potential drop across the slide wire of the potentiometer, and at balance only very small currents are drawn from the cell (depending on the sensitivity of the nnU detector used and the fineness of control possible in adjusting the slide wire). Alternatively a high-resolution digital voltmeter with a large internal impedance can be used. Potentiometers and digital voltmeters are described and compared in Chapter XVI. 

Mount the assembled cell in a thermostat bath. Either a potentiometer circuit or a high-resolution digital voltmeter can be used to measure the cell voltage (see Chapter XVI). In connecting the cell, consider the sign of AG for the change in state to decide on the proper connection. Have an instructor check your circuit. 

As discussed, maximum speed is determined when there is little stress on torque production resources. As resistance increases, speed will decrease. Therefore, the load must be considered and specified when testing speed. Because speed of movement data are calculated from displacement and temporal data, a key issue is minimizing error that might result from collecting this information. Error can result from inaccurate identification of anatomical landmarks, improper calibration, perspective error, instrument synchronization error, resolution, digitization error, or vibration. The sampling rate of some of the... 

The experimental set-up for video microscopy consists of a combination of a 50-mL gas-phase reactor with a microscope connected to a high-resolution digital camera that allows the observation of single catalyst grains during the whole polymerization [44].

Advanced instruments such as electron microscopy techniques (SEM and TEM) are used to characterize the microstructure of MEA components at various resolutions. Digital mapping of the morphology/catalyst clusters can be used to perform quantifafive analysis of the microstructure. 

It was reported that the rate of living cationic polymerization of IBVE with Al-based initiating systems was enhanced if the basicity of an added base was reduced. Thus, a weaker base was examined in the polymerization using SnCU and FeCU. An alternative weaker base, ethyl chloroacetate, realized very fast polymerization with SnCU in toluene at -78 °C, being completed within 2 s (determined using a high-resolution digital video camera).Moreover, FeCU induced faster polymerization with 1,3-dioxolane, a weaker base than 1,4-dioxane, which was completed in 2-3 s in toluene at 0 °C. ° In both cases, product polymers had very narrow MWD (Mw/Mn< 1.1), irrespective of the monomer conversion. 

An emerging technique in the last decades is based on the fusion of hyperspectral and Light Detection and Ranging (LiDAR) data, thanks to the increased availability of these data taken from the same area. In particular, in urban environment, the introduction of high-resolution digital surface models derived from LiDAR can effectively improve the classification and consequently the identification of different materials and surfaces.
