In this talk we consider a priori error estimates for an elliptic linear-quadratic Neumann boundary control problem with pointwise inequality constraints on the control. The domain is assumed to be polygonal and maybe non-convex. For discretizing the state linear finite elements are used, the control is approximated by piecewise constant ansatz functions. Approximations of the optimal control o...

A sphere moving down the surface of a static sphere and a simple phase diagram. Abstract A small sphere placed on the top of a big static fric-tionless sphere, slips until it leaves the surface at an angle θ l = cos −1 2/3. On the other extreme, if the surface of the big sphere has coefficient of static friction , µ s → ∞, the small sphere starts rolling and continues to do so until it leaves t...

The dualistic structure of statistical manifolds in information geometry yields eight types (possibly mixed type) geodesic triangles passing through three given points, the triangle vertices. interior angles can sum up to $$\pi $$ like Euclidean/Mahalanobis flat geometry, or exhibit otherwise angle excesses defects. In this work, we initiate study dually spaces, termed Bregman manifolds, where ...

Axial and lateral pressure loss in a 5 × rod–bundle with split-type mixing vane spacer grid was experimentally measured using differential transmitters at different sub-channel Reynolds numbers (Re) orienting angles. The geometrical parameters of the 5–rod bundle are as follows: they have same diameter (D = 9.5 mm) pitch ( p 12.6 those real fuel rods typical pressurized water reactor (PWR), hyd...

Tetrahedral Mesh Generation with Good Dihedral Angles Using Point Lattices by François Labelle Doctor of Philosophy in Computer Science University of California, Berkeley Professor Jonathan Shewchuk, Chair Three-dimensional meshes are frequently used to perform physical simulations in science and engineering. This involves decomposing a domain into a mesh of small elements, usually tetrahedra o...

Phase error compensation within motion compensation techniques requires range cell migration corrected SAR data. The main contribution of this paper is providing a non-approximated range cell migration correction (RCMC) for processing highly squinted SAR data. Embedded in the conventional Omega-K processing, the approach consists of two coordinate transformations carried out in the 2D frequency...

Abstract We show that all values in the interval $[0,{\pi }/{2}]$ can be attained as interior angles between intermediate subalgebras (as introduced by Bakshi and first named author [‘Lattice of subalgebras’, J. Lond. Math. Soc. (2) 104 (2021), 2082–2127]) a certain inclusion simple unital $C^*$ -algebras. also calculate crossed product any algebras corresponding to action countable discrete gr...

In the context of existence primordial black holes (PBHs), they may compose a fraction dark matter Universe. Assuming that PBHs fill content Milky Way Galaxy in Galactic halo and disk, we calculate probability collision with Earth. This has different consequences as heating interior earth through dynamical friction accretion processes. this work, rate collisions can be trapped inside earth. Fin...
