In the study of Kostka numbers and Catalan numbers, Kirillov posed a unimodality conjecture for the rectangular Narayana polynomials. We prove that the rectangular Narayana polynomials have only real zeros, and thereby confirm Kirillov's unimodality conje... see more

We show that some of the main structural constants for symmetric functions (Littlewood-Richardson coefficients, Kronecker coefficients, plethysm coefficients, and the Kostka–Foulkes polynomials) share symmetries related to the operations of taking complem... see more

Designing and maintaining open channels as well as studying nonuniform flow crucially depend on normal depth. In practical applications, the vaulted rectangular cross-section is widely applied. However, the form of the relationship determining the normal ... see more

We deduce Narayana's formula for the number of lattice paths that fit in a Young diagram as a direct consequence of the Gessel-Viennot theorem on non-intersecting lattice paths.

Using the combinatorial formula for the transformed Macdonald polynomials of Haglund, Haiman, and Loehr, we investigate the combinatorics of the symmetry relation ˜Hµ(x;q,t)=˜Hµ*(x;t,q)\widetilde{H}_\mu(\mathbf{x};q,t)=\widetilde{H}_{\mu^\ast}(\mathbf{x};... see more

Unmaned Aerial Vehicle (UAV) sering kali digunakan untuk melakukan misi pengintaian maupun pemantauan pada daerah yang sulit dijangkau oleh manusia sehingga dibutuhkan suatu antena dengan bentuk yang sederhana dan bobot yang ringan seperti antena mikrostr... see more

The study looks at the possibility of reducing the length of a rectangular hydraulic jump stilling basin by setting up a broad-crested sill. The conclusions of the study are based exclusively on laboratory tests using a specially designed hydraulic instal... see more

The study of hydraulic jumps in compound rectangular channels has been the subject of several featured contributions. For hydrotechnical structures such as dams, this type of channel has been used in the design of energy dissipation basins to control the ... see more

The present knowledge on the behavior of hydraulic jumps is only for smooth, horizontal channel beds. Very limited studies have been reported in the literature on the performance of hydraulic jumps on rough beds.The objective of our study is to investigat... see more
