A major challenge in fluidic assembly is the dynamically programmable fabrication of arbitrary geometries from basic components. Current approaches require predetermination of either the assembly machinery or the component interfaces for the specific target geometries. We present an alternative concept that exploits self-assembly forces locally but directs these forces globally, allowing fabric...

Introduction Dynamically Quantized (DO) spaces have been developed [O'Rourke] in response to the need for high-precision, high-dimensional Hough-like transforms. [Ballard; Sloan and Ballard) Their purpose is to cover a parameter space with a limited number of accumulators in such a way that fine precision is maintained where it is needed. O'Rourke's solution to this problem is to maintain a bin...

Distal tibiofibular syndesmosis injuries are complex injuries that often result in extended loss of playing time for athletes. Unstable syndesmosis injuries are uniformly reduced and stabilized by numerous methods. Controversy arises from syndesmosis injuries that are stable on stress radiographs but functionally unstable with loading of the ankle during athletic activity. The authors present a...

In the framework of dynamic choice under uncertainty, we define dynamic stability as a combination of two assumptions prevalent in the literature: dynamic consistency and the requirement that updated preferences belong to the same class as ex ante ones. Maxmin preferences are shown to be not dynamically stable, and any dynamically stable subset in that class can contain only expected utility pr...

Very long instruction word (VLIW) machines potentially provide the most direct way to exploit instruction-level parallelism; however, they cannot be used to emulate current general-purpose instruction set architectures. In addition, programs scheduled for a particular implementation of a VLIW model cannot be guaranteed to be binary compatible with other implementations of the same machine model...

A viscous flow model of a subduction zone is used to calculate the near-trench deformation and topography of the overriding plate in response to tectonic and buoyancy forces. The tectonic force, which is associated with global plate motion, arises from subduction of a cold oceanic lithosphere that shears the overriding lithosphere along the contact between the two plates. The buoyancy force ari...

Optical Tracking using ARToolkit provides us with the base technology for a wealth of Augmented Reality applications. However, marker-based optical tracking using a single camera has some drawbacks. Markers must be fully visible to the camera all the time to produce tracking output – occlusion by other objects and limited camera field of view constrain the area that can be effectively tracked b...

A polynomial with integer coefficients yields a family of dynamical systems indexed by primes as follows: For any prime p, reduce its coefficients mod p and consider its action on the field Fp. We say a subset of Z[x] is dynamically distinguishable mod p if the associated mod p dynamical systems are pairwise non-isomorphic. For any k, M ∈ Z>1, we prove that there are infinitely many sets of int...

The paper addresses the problem of mapping an application speciied as a task graph on a heterogeneous architecture which contains a software processor, a dynamically reconngurable hardware coprocessor and memory elements. The problem comprises of three sub-problems: partitioning of tasks between hardware and software, assigning tasks mapped on hardware to diierent temporal segments and scheduli...
