Energy loss in a manhole as junction of storm sewers or combined is an important factor for more accurate calculation inundation. The authors formulated energy coefficients two-way and three-way circular drop manholes where one two inflow pipes are connected to outflow pipe. Since there few studies on the four-way three pipe like at intersection, we conducted experiments which with several type...

Finite affine groups are given by groups of translations and di- lations on finite cyclic groups. For cyclic groups of prime order we develop a time-scale (wavelet) analysis and show that for a large class of non-zero window signals/vectors, the generated full cyclic wavelet system constitutes a frame whose canonical dual is a cyclic wavelet frame.

experimental study of the cyclic behavior of unsaturated materials is more complex than that of the saturated materials due to the required equipment, experience and time. furthering investigations in the field of unsaturated materials is necessary to better understand its complexity and sensitivity of unsaturated cyclic parameters to different determinants such as suction path, stress path, lo...

Abstract The gas storage regulations are intended to increase security of supply in winter. Tenders and direct procurement by the Market Area Coordinator should ensure that facilities filled. Both instruments can lead a displacement other volumes. Since potentially leads less allows for better control strategic behavior, it may be more effective. Tender design improved setting reserve price all...

The three-dimensional finite difference method was used in this study to analyze the deformation and stresses of a passive pile under surcharge load extensively deep soft soil. A numerical model proposed verified by field test. horizontal displacements agreed well with results. This investigated pile-foundation soil interaction, transfer mechanism, excess pore water pressure (EPWP), resistance ...

Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...

‎‎A natural generalization of two dimensional cyclic code ($T{TDC}$) is two dimensional skew cyclic code‎. ‎It is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $R_n:=F[x,y;rho,theta]/_l$‎. ‎In this paper we characterize the left ideals of the ring $R_n$ with two methods and find the generator matrix for two dimensional s...

In this paper, the free strain radial consolidation theory incorporating the changes of compressibility and permeability of the soil with the change in effective stress via time dependent surcharge preloading is presented. In contrast to the conventional analysis, the current study highlights the nonlinear characteristics of the soil during the consolidation process. A comparison of the nonline...
