This paper examines the nature of joint coupling in underactuated grippers for environments where object properties and location may not be well known. A grasper consisting of a pair of two-link planar fingers with compliant revolute joints was simulated as it was actuated after contact with a target object. The joint coupling configuration of the gripper was varied in order to maximize success...

We have studied the effect of different supports (CeO2, ZrO2, SiC, SiO2 and Al2O3) on catalytic performance phase stability Co3O4 nanoparticles during preferential oxidation CO (CO-PrOx) under H2-rich gas environments temperatures. Our results show that Co3O4/ZrO2 has superior activity, but transforms to Co0 consequently forms CH4 at relatively low The least reduced methanation active catalyst ...

Prox-regularity of a set (Poliquin-Rockafellar-Thibault, 2000), or its global version, proximal smoothness (Clarke-Stern-Wolenski, 1995) plays an important role in variational analysis, not only because it is associated with some fundamental properties as the local continuous differentiability of the function dist (C; ·), or the local uniqueness of the projection mapping, but also because in th...

Many modern applications involve collecting large amounts of data from multiple sources, and then aggregating and manipulating it in intricate ways. The complexity of such applications, combined with the size of the collected data, makes it difficult to understand the application logic and how information was derived. Data provenance has been proven helpful in this respect in different contexts...

Consensus optimization has received considerable attention in recent years. A number of decentralized algorithms have been proposed for convex consensus optimization. However, on consensus optimization with nonconvex objective functions, our understanding to the behavior of these algorithms is limited. When we lose convexity, we cannot hope for obtaining globally optimal solutions (though we st...

A series of mixed cobalt spinel catalysts (M x Co 3? O 4 = Cr, Fe, Mn, Ni, Cu, Zn)) was synthesized and tested in the CO-PROX reaction sole CO oxidation H 2 as references.

To the article “The Influence of Yttrium Stabilized Zirconia as Support Copper–Ceria Systems on Their Catalytic Properties in PROX Process,” by G. R. Kosmambetova, 56, No. 5, 319–323 (2020).

The catalytic performance of the bare Co 3 O 4 and mixed cobalt-spinel catalysts (M x 3? ; M = Cr, Mn, Fe, Ni, Cu, Zn) in CO-PROX process was investigated temperature-programmed surface reaction (TPSR) mode using 18 2 as an oxidant.

On-Line Monitoring (OLM) of a channel’s calibration state evaluates instrument channel performance by assessing its consistency with other plant indications. Industry and experience at several plants has shown this overall approach to be very effective in identifying instrument channels that are exhibiting degrading or inconsistent performance characteristics. The Halden Reactor Project has dev...
