A constructional scheme for making pressure cabins inraune from catastrophic failure without undue weight penalty It seems desirable to m&e some reference here to a construc-tional scheme put forward by the writer in a sequel to the present report". This scheme has its origin in paragraph 6 of Appendix D of the present report, where It is shown (see Fig.ZD) that when the former rings are reduce...

It is necessary to recognize masonry domes’ behavior under gravity loads in order strengthen, restore, and conserve them. The neutral hoop plays a crucial role identifying the dome’s distinguish between its tensile compressive regions. When it comes determining position dome with same brick material, addition curve thickness, support condition located on boundary line significant parameter that...

Free algebras with an arbitrary number of free generators in varieties of BL-algebras generated by one BL-chain that is an ordinal sum of a finite MV-chain Ln and a generalized BL-chain B are described in terms of weak Boolean products of BL-algebras that are ordinal sums of subalgebras of Ln and free algebras in the variety of basic hoops generated by B. The Boolean products are taken over the...

relative to a hereditary torsion theory $tau$ we introduce a dimension for a module $m$, called {em $tau$-rank of} $m$, which coincides with the reduced rank of $m$ whenever $tau$ is the goldie torsion theory. it is shown that the $tau$-rank of $m$ is measured by the length of certain decompositions of the $tau$-injective hull of $m$. moreover, some relations between the $tau$-rank of $m$ and c...

The Robopsy device is a lightweight, largely plastic telerobot (shown below in Fig. 1A) that affixes directly to a patient’s chest to pivot the needle in two degrees of freedom about a skin insertion point [1]. This is accomplished via two motor-actuated concentric, crossed and partially nested hoops. A medical image-based interface converts doctor clicks on the DICOM images to motor commands t...
