This paper presents a class of pipelined CORDIC architectures for the LMS-based transversal adaptive filter. For this, an alternate formulation of the LMS algorithm is considered, obtained by expressing the mean square error as a convex function of a set of angle variables that are monotonically related to the filter tap weights. The proposed architectures employ microlevel pipelining and are a...

In previous work, we demonstrated the feasibility of perceptual navigation algorithms used to intercept fly balls. In this paper we expand the optical acceleration cancellation heuristic to also intercept ground balls. We used computer simulations and experiments with mobile robots with various ball trajectories and different initial positions of the fielder to test our new model. A new robotic...

We used scaled experimental (analog) models with wet clay to investigate how conjugate sets of steeply dipping strike-slip faults affect deformation patterns during a subsequent phase of extension. In all twophase experiments, an initial phase of strike-slip deformation produces a long, wide deformation zone consisting of subvertical Riedel shears; synthetic R-shears and antithetic R'-shears tr...

In actual engineering, asymmetric flow often occurs, but rigid partitions are installed in the direction of field and symmetric direction. This will result a deflection angle between dividing plate incoming flow. The research results show that when declination is low, partition has limited impact on system; about 10 degrees, system vibration characteristics have abrupt changes, amplitude decrea...

STUDY DESIGN Systematic review with meta-analysis. OBJECTIVES To determine the biomechanical differences between foot-strike patterns used when running. BACKGROUND Strike patterns during running have received attention in the recent literature due to their potential mechanical differences and associated injury risks. METHODS Electronic databases (MEDLINE, Embase, LILACS, SciELO, and SPORT...

We perform a detailed parameter-space study on properties of yielding zones generated by 2-D in-plane dynamic ruptures on a planar fault with different friction laws and parameters, different initial stress conditions, different rock cohesion values, and different contrasts of elasticity and mass density across the fault. The focus is on cases corresponding to large strike-slip faults having hi...

We performed CT to investigate how treatment may modify the basic skeletal pathology of congenital club foot. Two homogenous groups of patients treated by one of the authors (EI) or under his supervision were studied. The first included 32 patients with 47 club feet reviewed at a mean age of 25 years and treated by manipulation, application of toe-to-groin plaster casts and an extensive postero...

Japanese dialects spoken in the Kinki and Shikoku regions have a lexical contrast of pitch register types called shiki. The shallow f0 downtrend in the high-pitched shiki type is thought of as a manifestation of backdrop f0 declination that is blind to tonal structure. Acoustic analysis of three Japanese dialects with 2or 3-way contrast of shiki types, however, reveals that the degree of f0 dec...
