This paper proposes a classification of three-revolute orthogonal manipulators that have at least one of their DH parameters equal to zero. This classification is based on the topology of their workspace. The workspace is characterized in a half-cross section by the singular curves. The workspace topology is defined by the number of cusps and nodes that appear on these singular curves. The mani...

The original CACTI tool was released in 1994 to give computer architects a fast tool to model SRAM caches. It has been widely adopted and used since. Two new versions were released to add area and active power modeling to CACTI. This new version adds a model for leakage power and updates the basic circuit structure and device parameters to better reflect the advances in scaling semiconductors w...

We study string propagation in a spacetime with positive cosmological constant, which includes a circle whose radius approaches a finite value as |t| → ∞, and goes to zero at t = 0. Near this cosmological singularity, the spacetime looks like IR/ZZ. In string theory, this spacetime must be extended by including four additional regions, two of which are compact. The other two introduce new asymp...

When choosing parameters for a tactile action, it is useful to be able to choose parameters that will optimize the discriminating power of the tactile data acquired during the action. We propose a way to extract this information about informative grasp parameters from a deep network trained to perform a classification task on the tactile data. We do this by defining a new cost function on the n...

We present results from fully two-dimensional physical device simulation. Scattering parameters (S-parameters) are directly obtained from small-signal AC-analysis of real heterostructure devices. A comparison reveals very good agreement with measured data.

We consider a model for the decay B 0 → ρ 0 γ in which the short-distance amplitude determined by the Hamiltonian describing b → dγ is combined with a typical long-distance contribution B 0 → D + D − → ρ 0 γ. The latter possesses a significant dynamical phase which induces a CP-violating asymmetry A CP , as well as an important modification of the Stokes vector of the photon.

This paper improves van Zyl’s Nonnegative Eigenvalue Decomposition (NNED). Orientation angle compensation and helix scattering are introduced to the decomposition. The volume scattering parameters that explain the most cross-polarized power are selected. If volume scattering and helix scattering explain all cross-polarized power in the measured coherency matrix, then simply perform van Zyl deco...

We investigate the equivalence between spectral characteristics of the Laplace operator on a metric graph, and the associated unitary scattering operator. We prove that the statistics of level spacings, and moments of observations in the eigenbases coincide in the limit that all bond lengths approach a positive constant value.

A electroweak theory without spontaneous symmetry breaking is studied in this paper. A new symmetry breaking of SU(2)L × U(1), axial-vector symmetry breaking, caused by the combination of the axial-vector component of the intermediate boson and the fermion mass is found in electroweak theory. The mass of the W boson is resulted in the combination of the axial-vector symmetry breaking and the ex...

We show that the large corrections due to final state interactions (FSI) in the D+ → π−π+π+ , D+ s → π−π+π+ , andD+ → K−π+π+ decays can be accounted for by invoking scattering amplitudes in agreement with those derived from phase shifts studies. In this way, broad/overlapping resonances in S-waves are properly treated and the phase motions of the transition amplitudes are driven by the scatteri...
