A stent has a substantially cylindrical tubular body with at least one expandable side branch that has a plurality of members. The plurality of members includes at least one first member having a first width and at least one second member having a second width, where the first width is greater than the second width. Each of the at least one first members and each of the at least one second members define a cell that has at least two stable cell geometries.

The present invention relates to an electric current management (ECM) system and method comprising at least one electrolytic cell having at least two electrodes in contact with electrolyte media; a plurality of sensor means for measuring the current passing through one or more electrodes, said sensor means being located inside at least one ECM bar installed in one or more operating electrolytic cells; a support means for supporting at least one ECM bar in each cell; wherein the support means is adapted to avoid disruption to normal electrode movements and damage to the ECM bar. The present invention introduces improvements for minimizing the effects that several types of variables have on current measurement, such as magnetic field interference, cell geometry and contact configuration, in order to provide a reliable approximation of the current passing through each electrode. The present invention can be applied to real time monitoring of each cathode, or anode, constituting a metal electrowinning or electrorefining cell or other electrolytic cell.

An improved cellular building block including a middle beam and two legs. The cellular building block having the first leg coupled to the middle beam such that the leg is perpendicular to the middle beam and a second leg coupled to the middle beam such that the leg is perpendicular to the middle beam and spaced apart from the first leg, the first leg and the second leg having an inside edge and an outside edge. Having at least one barb located on the inside edge of the first leg and on the inside edge of the second leg and further configured to lock into a recess. The cellular building blocks connect in a two dimensional or three dimensional pattern and a produce a structured material that holds itself together and exhibits beneficial characteristics.

The invention discloses an arc additive manufacturing finite element modeling method. The method comprises the following steps of: calculating an arc shape and determining the width of an additive area birth-death element; calculating a molten drop shape and determining the height of the additive area birth-death element; establishing an arc additive manufacturing finite element geometric model according to the width of the additive area birth-death element and the height of the additive area birth-death element; correcting the arc shape and the molten drop shape through verifying the temperature distribution of the arc additive manufacturing finite element geometric model, so as to correct the arc additive manufacturing finite element geometric model. According to the method disclosed by the invention, the geometric size of the additive area birth-death element can be determined before the arc additive manufacturing finite modeling by adopting an arc additive manufacturing simulation process, combining an arc shape simulation technology, a molten drop shape simulation technology and a finite element simulation technology and carrying out experimental verification, so as to realize the correct calculation of arc additive manufacturing finite element simulation.
