Analysis of wave spectrum by Blackman-Tukey method and fast fourier method

tailieu.vn

Whereas, FFT method helps us to analyze the shift of spectral energy as waves propagate into shallower water. The results show that wave energy is dissipated from shallow water to muddy flat and into mangrove forests. The spectral energy shifts from low frequency to higher frequency as propagating into mangrove forests. This can prove the non-linear characteristics of waves in mangrove forests and the complicated hydrodynamic processes in mangrove forests..

S A – the projection area of ship above water line to the midship section.. Added ship resistance in the shallow water. As many previous research suggests that when ship runs in the shallow water, there will be an increase in the resistance. Added ship resistance in the shallow water is determined as follows [11]:. C - the frictional resistance coefficient and residual added resistance in the shallow water respectively.. where: C F – coefficient of frictional resistance in deep water.

The beginning time of the first field of the variable is 0.

Pollution and health risks assessment of nitrate and phosphate concentrations in water bodies in South Eastern, Nigeria

tailieu.vn

When nitrate and phosphate ions concentrations in shallow water- bodies are in excess, there is overgrowth of water plants leading to the formation of algal bloom. This causes a high consumption of dis- solved oxygen in the water. Agbazue et al., 2015. Chloride, phosphate and sulphate anions are acidic and when ingested in high concentrations, change the acid-base equilibrium, creating more acidic conditions, a process that can lead to acidiosis ( Enyoh et al., 2018.

Healthcare data analysis using water wave optimization-based diagnostic model

tailieu.vn

When waves move from deep water to shallow water, the wavelength of the waves decrease in a significant manner. parameter is reset after execution of the refraction parameter and wavelength is computed using Equation 6.. PROPOSED WWO-BASED DIAGNOSTIC MODEL This section describes the WWO-based diagnostic model for disease diagnosis. The WWO-based clustering algorithm is implemented in the diagnosis phase. Before applying the WWO algorithm for clustering, some improvements are inculcated.

Diurnal time-activity budget and foraging techniques of red-crested pochards (Netta rufina) wintering at the wetlands of West Bengal, India

Multiple comparisons of the significant differences in the foraging techniques by male and female RCPs in December with deeper water habitats and January with shallow water habitats (at Site 3) using post hoc analysis with Tukey HSD (*differences were significant at P <0.05).. 0.8) were influential on the diurnal time activities of the RCPs.

The measurements fit the curve of dispersion relation in the shallow water limit, which means that the first resonant wave of the water tank is indeed in the shallow water limit regime. A partitioning wall is added to the tank so the length of the water tank is cm. In figure 9a the change in water height over time can be seen for a water depth of 8.9 ± 0.1 cm measured 40 cm left of the vertical partitioning wall.

If it is lower, the cans must be quickly reheated in a shallow water bath until the temperature in the middle of the tin. The time between filling, sealing and sterilizing must be as short as possible. These high temperatures can be reached only through increased pressure. Cover the bottom of the pressure canner with water.. Place the basket with the jars in the pressure canner. The holes in the basket must not all be blocked, as steam must be able to pass through.

Comparative transcriptomic analysis of deep- and shallow-water barnacle species (Cirripedia, Poecilasmatidae) provides insights into deep-sea adaptation of sessile crustaceans

Comparison of the protein-coding genes between the deep- and shallow-water barnacles, and with those of four other shallow-water crustaceans, revealed 26 gene families that had experienced significant expansion in G. warwicki indicated that 25 of them were distinctly positive selected in the deep-sea barnacle, including genes related to transcription, DNA repair, ligand binding, ion channels and energy metabolism, potentially indicating their importance for survival of G. gigas in the deep-sea environment

Although the Ediacara fauna is known from shallow-water onshore and offshore sandstones, deep- water turbidites, and shallow-water carbonates (Fedonkin 1987), it may be attributed to a single community of sessile filter and /or suspension feeders and to a few deposit feeders independently of the systematic interpretation of its members (Lipps et al..

To study how deep-sea creatures adapt to such a hostile environment, one of the most straightforward ways is to sequence and compare their genes with those of their shallow-water relatives.. Results: We captured an individual of the fish species Aldrovandia affinis, which is a typical deep-sea inhabitant, from the Okinawa Trough at a depth of 1550 m using a remotely operated vehicle (ROV).
