The study identifies the optimal UV wavelength for operation and measures device programming efficiency and data retention.
However, most optoelectronic devices are unable to retain data once the light source is turned off, which affects data persistence and reliability, requiring integration with non-volatile memory.
As shown in Figure 6 and 7, the device demonstrates distinct current responses and data retention under UVA, UVB, and UVC exposure, confirming the wavelength-dependent performance.
Data retention time of the device under UVA, UVB, and UVC exposure.

Studies on stresses around hole-edge and comparisons with test values show that simulated results of xσ and yσ agree well with test data and the relative errors are no more than 15%.
Fig.1 Test principle Test Results Test data are shown in table 1.Least-squares fitting method is used to determine coefficient k .

The two groups of data are very close indicating credible test results
The main reason is that the reduction of pre-tightening torque coefficient increases pre-tightening force, causing higher interface pressure between bolt and connecting part and larger load component transmitted by friction.

Pseudo-second-order models fitted the experimental data well and kinetic parameters, rate constants, equilibrium sorption capacity and related correlation coefficients at various temperatures were calculated and discussed.
Current technologies utilized for the removal of heavy metals from water include chemical precipitation[4], ion exchange[5], flotation[6], electrochemical reduction[7], and membrane separation [8].
The adsorption isotherm data were further analyzed in terms of the Langmuir isotherm model.
Various parameters are calculated from Langmuir isotherm models and in all cases, high regression coefficient values of R2 > 0.99 were obtained, suggesting that Langmuir isotherms fitted well for the experimental data[16].

Data were acquired from 100 kHz to 10 mHz at the rate of 10 points per decade and 5 mV signal amplitude around the OCP.
Compared to TiO2, Sn-doped TiO2 peaks shifted towards higher wavenumbers, suggesting a reduction in the molecular mass.
Based on the XRD data, the FWHM of the strongest (101) peak for TiO2 was 0.5117 rad and 0.6140 rad for Sn-doped TiO2.
Meanwhile, Fig. 7b shows the equivalent circuit used to analyze the EIS data for PVB and PVB + PANI/Sn-doped TiO2 on day 15 and 30.
The influence of the pinhole resulted in the reduction of Rp values while Cc values increased with time.

From these data, calorie and other nutritional element intake are estimated [3].
The results were promising, as summarized below: Ø Total of 12 parabola data were submitted for analysis.
Ø Data reduction encountered difficulty with large residual G onboard the airplane.
Due to residual G noise in the cabin, data analysis was difficult.
Extensive data analysis was tried [13, 14], but only one run data were recovered.

Based on the past historical data of earthquake few researchers proposed different analytical method for the prediction of future earthquake [14] but still it is difficult to predict exactly the earthquake based on analytical studies as recent earthquake in Kashmir-Pakistan in 2019 resulted in lot of casualties and damage to infrastructures [15].
All tests were carried out by applying the imposed displacement at a rate of 5mm/min and data were recorded using data acquisition system.
As a result, micro-cracking of concrete near corners occurred, further small reduction in cross sectional area due to chamfering also caused.

As straw is rarely used, data on the topic are divergent depending on countries and scientific publications.
Balance sheets of these data as well as building tests were necessary to select amplitude of variations to use in the thermal dynamic simulation software.
Data previously found allow us to determine also the interval for straw thermal diffusivity given in Eq. 4. 0,1 x 10-6 [m2.s-1] ≤ Diff ≤ 3,6 x 10-6 [m2.s-1]
A first thermal-dynamic model on Pleiades+Comfie Software was created using all the data available on site as 2013-2014 weather data of Lausanne, windows characteristics, internal devices, heating system regulation, clock and flow of the mechanical ventilation and also human behavior.
Energy performance of ECO46 straw bale building Using the straw characteristics from the previous part, the calibration of thermal-dynamic model was performed against two sets of temperature data in winter and summer period of the 2013-2014 year using the ASHRAE comparison method [8].

Any reduction in coronary blood flow can lead to infarction.
Rather than using three-dimensional reconstruction from medical images of the explored part of the vasculature, a simple representative model has been developed from our own observations and from literature data.
