We propose a covariant protocol for transmitting reference frames encoded on N spins, achieving sensitivity N-2 without the need of a preestablished reference frame and without using entanglement between sender and receiver. The protocol exploits the use of equivalent representations that were overlooked in the previous literature.

Nonholonomic distributions and adapted frame structures on (pseudo) Riemannian manifolds of even dimension are employed to build structures equivalent to almost Kähler geometry and which allows to perform a Fedosov-like quantization of gravity. The nonlinear connection formalism that was formally elaborated for Lagrange and Finsler geometry is implemented in classical and quantum Einstein gravity.

The standard approach to distribution amplitudes, which is due to Brodsky and Lepage , considers the hadron’s parton decomposition in the infinite momentum frame. A conceptually different, but mathematically equivalent formalism is the light-cone quantization . Either way, power suppressed contributions to exclusive processes in QCD, which are commonly referred to as higher twist corrections, a...

Experimental results from a frame size 180 brushless doubly fed (induction) machine (BDFM) fitted with four rotor designs are presented. The machine is intended for use as a variable speed generator, or drive. A per phase equivalent circuit for the machine has been developed and a method of obtaining parameters for the circuit is described. Expressions for the torque as a function of speed have...

Let C(L) be the ring of real-valued continuous functions on a frame L. In this paper, strongly fixed ideals and characterization of maximal ideals of C(L) which is used with strongly fixed are introduced. In the case of weakly spatial frames this characterization is equivalent to the compactness of frames. Besides, the relation of the two concepts, fixed and strongly fixed ideals of C(L), is st...

Bar frame modelling is a popular method in coupled shear wall systems in structural design. In this process, determining the stiffness of the tie beams is important. In this study, results obtained by finite-element analysis of R/C coupled shear wall systems having several geometries in elastic-plastic space are considered. Using SPSS (Ver.5.0) statistical package program, an equivalent tie bea...

The human visual system can represent an object's spatial structure with respect to multiple frames of reference. It can also utilize multiple reference frames to mentally transform such representations. Recent studies have shown that performance on some mental transformations is not equivalent: Imagined object rotations tend to be more difficult than imagined viewer rotations. We reviewed seve...

A high-qulaity speech coding method (SPMEX) at 4.8 kb/s is proposed. The SPMEX selects a suitable excitation signal, based on the decision from aconstic features of speech signal in a frame. lmproved pitch interpolation multi-pulse (PMPC) excitation is selected for vowel-like speech. In PMPC, multi-pulse during only one pitch period is calculated in the frame. Fnrther, gain and phase adjusting ...

We review some logic formalisms which were designed in order to reason about situations, goals, and actions. In particular, we focuss on the so-called frame problem, ie. the technical problem of how to formalize the assumption that unless an action explicitly causes a certain fact to hold or not to hold, the facts are preserved by the action. It is shown that there is no need to explicitly stat...

The previously introduced algorithm SQEMA computes first-order frame equivalents for modal formulae and also proves their canonicity. Here we extend SQEMA with an additional rule based on a recursive version of Ackermann’s lemma, which enables the algorithm to compute local frame equivalents of modal formulae in the extension of first-order logic with monadic least fixed-points FOμ. This comput...
