Authors: Ile Mircheski, Andrzej Łukaszewicz, and Ryszard Szczebiot
Abstract: The purpose of the paper is to present the design of new bicycle plastic bottle holder and injection process simulation. The model of plastic bottle holder was designed and simulated to determine injection parameters in SolidWorks environment. Based on main part’s 3D m0del the mold tool was created. From the virtual testing the most suitable injection point location, material temperature as well as fill time and required injection pressure have been specified.2019-04-01T00:00:00ZDesign of a street-style motorcycle conceptRizov, TashkoTashevski, RistoNajdeski, Hristijanhttp://hdl.handle.net/20.500.12188/19682019-04-19T22:02:23Z2019-01-01T00:00:00ZTitle: Design of a street-style motorcycle concept

Authors: Milutin Obradovic; Nikola Tuneski
Abstract: In this paper we study the class $\mathcal{U}$ of functions that are analytic
in the open unit disk ${\mathbb D}=\{z:|z|<1\}$, normalized such that
$f(0)=f'(0)-1=0$ and satisfy \[\left|\left [\frac{z}{f(z)} \right]^{2}f'(z)-1
\right|<1\quad\quad (z\in {\mathbb D}).\] For functions in the class
$\mathcal{U}$ we give sharp estimate of the second ant the third Hankel
determinant, its relationship with the class of $\alpha$-convex functions, as
well as certain starlike properties.2018-12-20T00:00:00ZHankel determinant for a class of analytic functionsMilutin ObradovicNikola Tuneskihttp://hdl.handle.net/20.500.12188/17892019-03-26T09:00:39Z2019-03-19T00:00:00ZTitle: Hankel determinant for a class of analytic functions
Authors: Milutin Obradovic; Nikola Tuneski
Abstract: Let $f$ be analutic in the unit disk $\mathbb D$ and normalized so that
$f(z)=z+a_2z^2+a_3z^3+\cdots$. In this paper we give sharp bound of Hankel
determinant of the second order for the class of analytic unctions satisfying
\[ \left|\arg \left[\left(\frac{z}{f(z)}\right)^{1+\alpha}f'(z) \right]
\right|<\gamma\frac{\pi}{2} \quad\quad (z\in\mathbb D),\] for $0<\alpha<1$ and
$0<\gamma\leq1$.2019-03-19T00:00:00Z
