On Numerical Characteristics of а Simplex and their Estimates
Моделирование и анализ информационных систем, 2016 Let \(n\in {\mathbb N}\), and let \(Q_n=[0,1]^n\) be the \(n\)-dimensionalunit cube. For a nondegenerate simplex \(S\subset {\mathbb R}^n\), by\(\sigma S\) we denote the homothetic image of \(S\)with the center of homothety in the center of gravity of S ...

On Some Problem for a Simplex and a Cube in Rⁿ
Моделирование и анализ информационных систем, 2013 Let S be a nondegenerate simplex in Rⁿ. Denote by α(S) the minimal σ > 0 such that the unit cube Qn:= [0, 1]ⁿ is contained in a translate of σS. In the case α(S) ≠ 1 the translate of α(S)S containing Qn is a homothetic copy of S with the homothety ...

STRAIN GAUGE ANALYSIS OF AXIAL AND OFF AXIAL LOADING ON IMPLANTS FOR REPLACING FIRST MANDIBULAR MOLAR (INVITRO STUDY) [PDF]
Alexandria Dental Journal, 2019 INTRODUCTION: Mechanical overload is thought to be one of the major causes of implant complications. It may induce loosening and fracture of the superstructure and/or implant components. Bone loss may also occur at the implant-bone interface.
