Constant Propagation Versus Join Reordering

, 2008
1 Introduction Two topics of research in the area of query evaluation for recursive Datalog rules have been constant propagation and join ordering. In the former, given a recursive Datalog program with a constant in the query, the goal is to propagate ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Demand-Driven Interprocedural Constant Propagation: Implementation and Evaluation

, 1994
We have developed a hybrid algorithm for interprocedural constant propagation combining the Wegman-Zadeck, Burke and Cytron, and demand-driven approaches. We use a modified Wegman-Zadeck algorithm as the incremental intraprocedural constant propagator in

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Laju perambatan retak plat aluminium 2024 T3 dengan beban fatigue uniaksial pada rasio beban dan jarak diameter lubang berbeda

Jurnal Energi Dan Manufaktur, 2012
Producing of component by machining process can yield component defective. That defective in crack form, although it probably is very litlle. If that defective is applied by a syclic load, the defective exist will propagate with a propagation rate until ...

On the Impact of Wavelength Dependency on Supercontinuum Generation in Photonic Crystal Fibers

Applied Sciences
It is common practice when simulating propagation through an optical fiber to assume that its characteristic parameters are constant and determined solely by the central wavelength of the input pulse.

Constant Propagation: A Fresh, Demand-Driven Look

, 1994
Constant propagation is a well-known static compiler technique in which values of variables which are determined to be constants can be passed to expressions which use these constants.

Determination of permittivity from propagation constant measurements in optical fibers

, 2015
We present a new method for determination of dielectric permittivity constant using measurements of fundamental mode of propagation constant in optical fiber’s.

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Equivalent Circuits for Microwave Metamaterial Planar Components

Sensors
Metamaterial components and antennas are based on the general understanding that an artificial structure composed of adequately designed and manufactured elementary cells or arrays has unusual resonance and propagation properties.
