Data analysis For data analysis the free available computer program MePASto [2] was used for first tests.
MePASto allows an automated data reduction from Doppler-coincidence spectra supplemented by a post-processing unit for data analysis.
To speed up CDB data processing flow new program called CDBtool was developed.
Fig. 2 Histogram recalculation Fig. 1 CDB diagram with the diagonal cut filter for data extraction The input two-dimensional spectrum for every measurement is available as a plain ASCII file in the form of a matrix, typically consisting of 1025x1025 data set entries.

In this paper, the traffic flow data before and after the FSM Bridge maintenance are presented along with the marine line data, especially for the redistribution of the traffic during the rehabilitation work at the FSM Bridge.
According to these results, the capacity reduction on FSM Bridge was satisfied by marine transportation and Bosphorus Bridge.
Table 3 provides the passenger data from the City Ferry Lines after the FSM Bridge maintenance works started.
As can be seen from the data, the maintenance works on FSM Bridge generated remarkable increases in marine transportation of Istanbul, especially on peak lines and lines around Bosphorus Bridge.
Based on the findings from the data, we recommend new parallel marine lines in Bosphorus, encouragement of highway vehicles (especially bus and minibus service vehicles) to take efficient new ferryboat lines, more efficient usage of existing city line ferries thus relieving highway traffic.

The correlation between the observed pseudo-first order degradation rates coefficients of PAHs (kobs) at linear data (in 30 minutes reaction time) and ZVI concentration is shown in Fig. 3.

In turn, glyphosate inhibits the activity of HRP and causes a reduction of the electric current density in the biosensor electrode.
Parameters were set to 1.0 V and recorded for a total time of 900 s with data recording interval of 0.5 s.

The optimum parameter for microwave sintering is 1320°C for 1h, which is about 300°C lower than conventional carbonization reduction to obtain ZrB2 powders.
The precursor was sintered in a high-vacuum microwave furnace (HAMiLab-HV3, SYNOTHERM co., Changsha, China) at 1300°C–1400°C under Ar atmosphere at a heating rate of 20°C/min below 1100°C and then 10°C/min up to the target temperature by the High-temperature boro/carbothermal reduction reaction method.
According to the XRD data results of phase analysis, ZrB2 can be synthesized at 1100°C, which is below the theoretical temperature of transition.
This temperature is about 300°C lower than conventional carbonization reduction to obtain ZrB2 powders.

Total organic carbon (TOC) across the amendments showed reduction in value; 47% in TS (tea and sugarcane bagasse), whereas 25% in TS6M (Tea + sugarcane bagasse + 6 microbes) and 68% in TS3M (tea bagasse + 3 microbes).
The process often results into mass reduction, a shorter time of processing and generation of high levels of humus with reduced phytotoxicity.
The data revealed significant decrease in total organic carbon (TOC) at the end of experiments duration across the treatments.
Table 3 showed reductions in worm weight across the treatments but was more pronounced in the TS3M treatment.
However, Figure 1 might explain that the reduction in worm weight is a reflection of faster degradation.

It is also shown that the heat is transferred at a further downstream distance allowing in a reduction in the number of VGs to be used in of “flow down” case.
The results are validated against (PIV) experimental data previously performed by [5].
In the present study, several turbulence model simulations have been performed for various mesh distributions to ensure the results are grid-independent and the best model has been chosen as“Standard k-ε” turbulence model based on the comparison with the experimental data as shown in Fig. 3.
With this element sizes, there is a good agreement between the numerical results and the experimental data as shown in Fig. 3.

Ni was incorporated by refluxing over sulfated zirconia, followed by calcination-reduction process.
Optimized sulfation likely affects the reduction of crystallite size of zirconia.
The average crystallites size of all sample, D [nm] was estimated as supporting data and listed in Table. 1.
Moreover, the diffraction peak of sulfated zirconia slightly shifted to a higher 2θ value when the calcination temperature was more than 600°C, which means the crystallite was enlarger, being in mutual accord to the data in Tabel. 1.
These data are given in Fig. 6.

The PWM output signal is set to logical “1’’ at the beginning of the switching period and is reset after a number of clock cycles equal to the integer value of the N-bit data input.
The system input is an N-bit data word, corresponding to the desired PWM duty cycle value, so that it can be easily interfaced to a microcontroller unit I/O port pins.
The N-bit register output, containing the N-bit data input, is compared with the output value of an N-bit free-running synchronous counter, by means of a comparator.
Also, the counter overflow signal is used to load the N-bit data input to the input register, so that the PWM output duty cycle change is performed at the new PWM wave period in order to avoid any frequency and/or phase jitter of the output waveform. while its duty cycle is given from the following equation: Where Data_Value is the input data word integer value.
The maximum clock frequency and the maximum PWM signal frequency for 8, 7 and 6-bit data input configurations, are tabulated in Table 4.

The investigation uses real data from material gatherers’ association in the city of Itajubá, Minas Gerais, Brazil.
The research utilizes data from a recyclable materials gatherers’ association from the city Itajubá, located in the southeastern Brazilian state of Minas Gerais.
Materials and Methods Data collection for this study was carried out by means of interviews and direct observations.
To facilitate the geo-referenced data collection of the ACIMAR collection and transportation system, a GPS device was used (Garmin Oregon 300).
In doing so, data were collected for all stopping points along the route, the corresponding neighborhoods, the distances and total times for each trajectory, the speed driven, etc.
