[1] Seismic tomography images of the upper mantle structures beneath the Pacific Northwestern United States display a maze of high-velocity anomalies, many of which produce distorted waveforms evident in the USArray observations indicative of the Juan de Fuca (JdF) slab. The inferred location of the slab agrees quite well with existing contour lines defining the slab’s upper interface. Syntheti...

S U M M A R Y Data from three seismic arrays installed in southern Peruwere analysed using receiver functions from P, PP and PKP wave phases, in order to image the subducted Nazca slab. The arrays cover the transition region from flat slab subduction in central Peru to normal subduction with an angle of about 30◦ further south. A previous study used data from the first array in the normal subdu...

We propose an adaptive lossy joint source-channel coding (JSCC) scheme for sending correlated sources over two-terminal discrete-memoryless two-way channels (DM-TWCs). The main idea is to couple the independent operations of terminals via mechanism, which can mitigate cross-interference resulting from simultaneous channel transmissions and concurrently exploit sources' correlation reduce end-to...

Reheating of steel slabs in a reheating furnace is an intermediate step the long and complicated process making. Reheat furnaces heat to about 1200 °C, which makes suitable for hot rolling. During this temperature uniformity within slab very important. A detailed understanding hence, important both from perspective product quality energy use. Unfortunately, extreme conditions inside do not allo...

We show that, on inputs of length exceeding 5n, any n-state unary two-way nondeterministic 4nite automaton (2nfa) can be simulated by a (2n+2)-state quasi-sweeping 2nfa. Such a result, besides providing a “normal form” for 2nfa’s, enables us to get a subexponential simulation of unary 2nfa’s by two-way deterministic 4nite automata (2dfa’s). In fact, we prove that any n-state unary 2nfa can be s...

Hollow slabs are of reinforced concrete in which voids allow the to be reduced size. This type slab results raw materials Consumption and increased insulating properties achieve sustainability goals. paper reported an experimental research program focused on study bending behaviour elements hollow normal-strength concrete. Three models one-way were cast, It had dimensions 1020 mm length, 420 wi...
