Ever since Hobbes we have sought to explain such extraordinarily commonplace facts as that prudent people trust each other, keep promises and succeed by and large at coordinating so as not to collide in corridors and roadways. In fact, it is the success which meets our efforts to coordinate without communication so as not to collide in corridors, which is perhaps the most perplexing of all soci...

Multiple input multiple output (MIMO) systems have assumed great importance in recent times because of their remarkably higher capacity compared to single input single output (SISO) systems. One of the most celebrated results in this context is that the capacity of a point-to-point MIMO system withM inputs andN outputs increases linearly as min(M;N) at high SNR. For power and bandwidth limited ...

We present a heuristic approach to the geometric motion-planning problem with the aim to quickly solve intuitively simple problems. It is based on a divide -and-conquer path search strategy, which makes inquiries about feasible paths, an efficient collision detection scheme is developed that handles translations and rotations of polyhedral to compute all times of collision. The whole algorithm ...

We study how some recently proposed noncontextuality tests based on quantum interferometry are affected if the test particles propagate as open systems in presence of a gaussian stochastic background. We show that physical consistency requires the resulting markovian dissipative time-evolution to be completely positive.

The well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. A new model that was previously proposed by the authors that combines a mass with a pulley (MP) is shown to simulat...

This work intends to deal with the optimal kinematic synthesis problem of Tricept parallel manipulator. Observing that cuboid workspaces are desirable for most machines, we use the concept of effective inscribed cuboid workspace, which reflects requirements on the workspace shape, volume and quality, simultaneously. The effectiveness of a workspace is characterized by the dexterity of the manip...

Optimizing bioprocesses requires an in-depth understanding, from a bioengineering perspective, of the cultivation systems used. A characterization is typically performed via experimental or numerical methods, which are particularly well-established for stirred bioreactors. For unstirred, non-rigid such as wave-mixed bioreactors, methods prove to be problematic, often only simplified geometries ...
