(a) (b) Fig.1 Shows the contact resistance data (ρc) with (a) annealing process time 15 sec and (b) annealing process time 30 sec as a function of the annealing temperature and annealing time Figure 1 shows the contact resistance data (ρc) with (a) annealing process time 15 sec and (b) annealing process time 30 sec that determines the relationship of the samples.
With the increase in the annealing temperature and annealing time, a great deal of Al diffuses into the AlGaN surface and reacts with the Ti, resulting in a resistance reduction.

Fig. 1a showed the UV–vis absorption spectra of the polymers in solution and thin films, and the corresponding data were summarized in Table 2.
Table 2 Optical properties and electrochemical data of the polymers.
(3) Electrochemical properties The electrochemical properties of the polymers were investigated by cyclic voltammetry (CV) and shown in Fig. 2 to estimate the redox behavior of the polymers and estimate the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels, and the corresponding are collected in Table 2.The onset potentials for oxidation (Eox) and reduction (Ered) of the polymers were measured by CV, where SCE electrode was used as the reference electrode, and the HOMO and LUMO energy levels and electrochemical bandgaps (Eg) of polymers were calculated with the following equations [9].
As a result, the PCEs for the three polymers are in the order of P1 > P2 > P3, and the corresponding data is 0.64 %, 0.58 %, 0.07 %.

In opinion of authors mathematical models and limiting condition criterion initial data for development of a definition technique limiting condition of long-term working technical equipment , (1) V – indirect (instrumental) characteristic index, АC – acoustic characteristics, PМ – proximate method limiting condition term.
The proved and chosen method of acoustic structuroscopy (АC), physicomechanical properties and also results of metallophysical research of steel (PМ) represents initial data for metal condition the acoustic characteristics to determinate.
It is established, to increase in size of local internal stress fields (average bending-torsion of a crystal lattice) there is a growth of time of SAW delay that explains relaxation of ultrasonic fluctuations sources (concentrators) internal stress fields, and with decrease in source density, reduction of bending-torsion of a crystal lattice and sizes of local internal stress fields the relaxation degree of ultrasonic fluctuations decreases also time of a delay of SAW falls.
Data of acoustic characteristic measurement gives a good concurrence to results of metalographic researches [7,8].

Research data in the form of secondary data was taken through the Indonesian Geospatial Data Portal of the Geospatial Information Agency and data from the Watershed Management Information System of the Ministry of Environment and Forestry.
By mapping data, we can identify spatial and temporal patterns that may not be visible if the data is only presented in the form of tables or graphs.
Study Area and Data The Latuppa Watershed was chosen as a research area because the research area is always flooded, although the flood rate varies every year.
The data source of this study was obtained from the Indonesian Geospatial Data Portal of the Geospatial Information Agency such as: Shapefile data on slope, soil type, land elevation, rainfall, land use, and river flow density.
The watershed boundary data shapefile is obtained from the watershed management information system data of the Ministry of Environment and Forestry.

In this paper, the theoretical background of the model is discussed, and the results are compared to experimental data.
However, this quantity can straightforwardly be calculated from the thermodynamic data used to evaluate chemical potentials and chemical driving forces.
It can be shown that entropic effects will lead to a reduction of the interfacial energy, thereby enhancing the effect of geometry and further decreasing γ.
The simulation results are compared to the experimental data reported in [21].
