Tujuan penelitian ini adalah untuk mengetahui hasil perbandingan tingkat kenyamanan pasien, proyeksi yang lebih memudahkan radiografer. dan informasi anatomi pada proyeksi AP Axial Plantodorsal dan proyeksi AP Axial Dorsoplantar. Penulisan karya tulis ini menggunakan metode kuantitatif dengan pendekatan eksperimen, metode tersebut yaitu penulis turun ke lapangan melakukan eksposi kepada relawan yaitu menggunakan proyeksi AP Axial Plantodorsal dan proyeksi AP Axial Dorsoplantar dan membandingkan hasil radiograf dari proyeksi AP Axial Plantodorsal dan proyeksi AP Axial Dorsoplantar. Metode pengumpulan data yaitu dengan cara memberikan kuesioner kepada 10 orang relawan untuk menilai kenyamanan pasien, memberikan kuesioner kepada 3 orang radiografer untuk menilai kemudahan mengerjakan proyeksi dan yang terakhir diberikan kuesioner kepada 3 orang dokter untuk menilai informasi anatomi yang data tersebut akan diolah menggunakanan aplikasi SPSS. Dari pengolahan dan analisis data diperoleh hasil penelitian bahwa dengan menggunakan proyeksi AP Axial Plantodorsal lebih optimal dalam memberikan informasi anatomi
We study the Cauchy problem for the quasi-geostrophic equations in a unit ball of the two dimensional space with the homogeneous Dirichlet boundary condition. We show the existence, the uniqueness of the strong solution in the framework of Besov spaces. We establish a spectral localization technique and commutator estimates.
We consider variational integrals of the form $\int F(D^2u)$ where $F$ is convex and smooth on the Hessian space. We show that a critical point $u\in W^{2,\infty}$ of such a functional under compactly supported variations is smooth if the Hessian of $u$ has a small oscillation.
The main topic of this note is a discussion of applicability conditions of the Nehari manifold method depending on the value of parameters of equations. As the main tool, we apply the nonlinear generalized Rayleigh quotient method.
Initial boundary value problems for the three dimensional Kuramoto-Sivashinsky equation posed on unbounded 3D grooves were considered. The existence and uniqueness of global strong solutions as well as their exponential decay have been established.
In this paper, we consider the zero-viscosity limit of the 2D steady Navier-Stokes equations in $(0,L)\times\mathbb{R}^+$ with non-slip boundary conditions. By estimating the stream-function of the remainder, we justify the validity of the Prandtl boundary layer expansions.
We show that convex viscosity solutions of the Lagrangian mean curvature equation are regular if the Lagrangian phase has Hölder continuous second derivatives.
We prove a generalized version of Friedrichs and Gaffney inequalities for a bounded $(\varepsilon,δ)$ domain $Ω\subset\mathbb{R}^n$, $n=2,3$, by adapting the methods of Jones to our framework.
We study some regularity issues for solutions of non-autonomous obstacle problems with $(p,q)$-growth. Under suitable assumptions, our analysis covers the main models available in the literature.
The $α$-patch model is used to study aspects of fluid equations. We show that solutions of this model form singularities in finite time and give a characterization of the solution profile at the singular time.
This article sets forth results on the existence, positivity and boundedness of solutions for quasilinear elliptic systems involving p-Laplacian and q-Laplacian operators. The approach combines Schaefer's fixed point, comparison principle as well as Moser's iteration procedure.
In this paper, we consider the nonlinear elliptic equations on rectangular tori. Using methods in the study of KAM theory and Anderson localization, we prove that these equations admit many analytic solutions.
We prove Strichartz estimates without loss for the Schrödinger equation and the wave equation outside finitely many strictly convex obstacles verifying Ikawa's condition, extending the approach we introduced previously for the two convex case.
In this paper we prove an almost sure local well-posedness result for the periodic 3D quintic nonlinear Schrödinger equation in the supercritical regime, that is below the critical space $H^1(\mathbb T^3)$.
We consider the existence of strong solution to liquid crystals system in critical Besov space,then give a criterion which is similar to Serrin's criterion on regularity of weak solution to Navier-Stokes equations.
In this paper, we prove the diffusion phenomenon for the linear wave equation with space-dependent damping. We prove that the asymptotic profile of the solution is given by a solution of the corresponding heat equation in the $L^2$-sense.
The decay properties of the semigroup generated by a linear Timoshenko system with fading memory are discussed. Uniform stability is shown to occur within a necessary and sufficient condition on the memory kernel.
