Optimizing land leveling by applying warped surface
In this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. The objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. We develop a warp...
متن کاملConstruction of a surface pencil with a common special surface curve
In this study, we introduce a new type of surface curves called $D$-type curve. This curve is defined by the property that the unit Darboux vector $vec{W}_{0} $ of a surface curve $vec{r}(s)$ and unit surface normal $vec{n} $ along the curve $vec{r}(s)$ satisfy the condition $leftlangle vec{n} ,vec{W}_{0} rightrangle =text{constant}$. We point out that a $D$-type curve is a geodesic curve or an...
متن کاملLinear series on a special rational surface
We study a result of Postnikov-Shapiro concerning the Hilbert series of a family of ideals Jφ generated by powers of linear forms in k[x1, . . . , xn]. Using the results of Emsalem-Iarrobino, we formulate this as a problem about fatpoints in P. In the three variable case this is equivalent to studying the dimension of a linear series on a blow up of P. The ideals that arise have the points in v...
متن کاملLinear systems on a special rational surface
We study the Hilbert series of a family of ideals Jφ generated by powers of linear forms in K[x1, . . . , xn]. Using the results of Emsalem-Iarrobino, we formulate this as a question about fatpoints in P. In the three variable case this is equivalent to studying the dimension of a linear system on a blow up of P. The ideals that arise have the points in very special position, but because there ...
