Laser Doppler velocimetry is a technique used to measure linear velocity, ranging from that of exhaust gases to blood flow. A rotational analog of laser Doppler velocimetry was recently demonstrated, using a rotationally symmetric interference pattern to probe the angular velocity of a spinning object. In this work, we demonstrate the use of a diffraction-limited structured illumination pattern...

We study the skeleton of several polytopes related to the n-cube, the halved n-cube, and the folded n-cube. In particular, the Gale polytope of the n-cube, its dual and the duals of the halved n-cube and the complete bipartite sub-graphs polytope.

Centrifugal pumps are an integral part of plants used in process industries. The flow structure within a centrifugal pump is very complex due to the interaction between the rotating impeller and the geometric features around it. In the present study, numerical investigations on a centrifugal pump have been carried out using a Computational Fluid Dynamics (CFD) based solver. This study employs f...

INTRODUCTION Optical trapping is a laser-based method for probing the physiological and mechanical properties of cells in a noninvasive manner. As sperm motility is an important criterion for assessing the male fertility potential, this technique is used to study sperm cell motility behavior and rotational dynamics. METHODS AND PATIENTS An integrated optical system with near-infrared laser be...

We revisit the Raz-Safra plane-vs.-plane test and study the closely related cube vs. cube test. In this test the tester has access to a “cubes table” which assigns to every cube a low degree polynomial. The tester randomly selects two cubes (affine sub-spaces of dimension 3) that intersect on a point x ∈ F, and checks that the assignments to the cubes agree with each other on the point x. Our m...

The cube attack is a powerful cryptanalysis technique against symmetric primitives, especially for stream ciphers. One of the key step in recovering superpoly. division property has been introduced to attacks with aim first identify variables/monomials that are not involved Recently, some improved versions this allowing recovery exact superpoly have developed and applied on various ciphers [13,...

Data cube construction is a commonly used operation in data warehouses. Because of the volume of data stored and analyzed in a data warehouse and the amount of computation involved in data cube construction, incremental maintenance of data cube is really effective. To maintain a data cube incrementally, previous methods were mainly for relational databases. In this paper, we employ an extendibl...
