Introduction. The presses are powered machines having stationary beds and slides (rams) which have controlled sliding motion towards away from the beds, guided by frames. Metal can be worked in power press a wide verity of ways like punching, shearing, forming, etc. Crankshaft is one basic components for transmission, transmits rotary to mechanical press. It around this element that all stresse...

The familiar classical result that a continuous map from a space $X$ to a space $Y$ can be defined by giving continuous maps $varphi_U: U to Y$ on each member $U$ of an open cover ${mathfrak C}$ of $X$ such that $varphi_Umid U cap V = varphi_V mid U cap V$ for all $U,V in {mathfrak C}$ was recently shown to have an exact analogue in pointfree topology, and the same was done for the familiar cla...

Intercalation of lithium into Ag-CNTs sample is reported here. We have used a nano-porous silver foam as a frame for deposition of the CNTs   inside   the   pores   by   electrophoresis   deposition   (EPD) technique. By using  chronopotentiometry method,  we  have noticed that the Li storage capacity of the prepared Ag-CNTs electrode was improved  noticeably  in  comparison  with  literature. ...

by minimizing the total potential energy function and deploying the virtual work principle, a higher-order stiffness matrix is achieved. this new tangent stiffness matrix is used to solve the frame with geometric nonlinear behavior. since authors’ formulation takes into account the higher-order terms of the strain vector, the convergence speed of the solution process will increase. in fact, bot...

We consider a generator F 1⁄4 ðf1; y ;fNÞ for either a multi-frame or a super-frame generated under the action of a projective unitary representation for a discrete countable group. Examples of such frames include Gabor multi-frames, Gabor super-frames and frames for shift-invariant subspaces. We show that there exists a unique normalized tight multi-frame (resp. super-frame) generator C 1⁄4 ðc...

The constants A and B are called lower and upper frame bounds for the frame. We call a frame {fi}i∈I bounded, if there exists δ > 0 such that ‖fi‖ ≥ δ for all i ∈ I (the norms of the frame elements are always uniformly bounded from above [3, Proposition 4.6]), and unit norm, if ‖fi‖ = 1 for all i ∈ I. If {fi}i∈I is a frame only for its closed linear span, we call it a frame sequence. Those sequ...

In J. T. Wilson’s doctoral dissertation, the author takes up the subject of free meets, that is, subsets S of a frame L whose meet V S is preserved by a designated class of frame homomorphisms out of L. Wilson proves that all subsets of L have free meets if and only if the dual frame law holds in L and the assembly NL is a boolean frame. In this paper it is shown that for algebraic frames L wit...

The frame analysis of Olympics-related news is quite popular, yet few studies do comparative two Olympics hosted by ideologically similar countries. To fill this gap in the literature, study examined similarities and differences an American agency CNN’s (Cable News Networks) coverages 2014 Sochi Winter 2022 Beijing Olympics. Under theoretical framework framing theory, a content (N = 200) storie...
