The latent hardening produced by straining copper crystals in single glide was investigated measuring the flow stress on secondary systems. Specimens oriented for slip these systems were spark cut from large prestrained and tested tension. These specimens did not always yield most highly stressed system; this behavior is a manifestation of anisotropy introduced prestrain found only certain portions stereographic projection.When plane changed, increased. increase ranged 160% early stage I to...
Abstract Copper single crystals were strained in tension after being extraneously deformed either by twisting or spark damaging. In both cases a transient region of low hardening was observed extraneous deformation. Slip line studies showed that this associated with slip band formation and inhomogeneous deformation along the gauge length. The dislocation distributions studied an etch pit technique. It found is accompanied multiplication on main glide plane but not other planes. proposed are...
Abstract The mechanism of slip in copper crystals with extraneously deformed surfaces was investigated using an etch pit technique. Some suggestions are made as to the deformation hard surface layers. Slip oriented for multiple glide and polycrystals is also discussed. Experiments latent hardening type were carried out on by altering system during course deformation. Phenomena characteristic alien dislocation distributions observed when plane changed but not only direction altered. stability...
About 80 percent of British deep mined coal is obtained from advance longwall faces. This mining method highly capital intensive. Therefore, it important to know the geologic structure prior mining. Small faults can have a large effect on production rates. Channel wave seismology offers possible for locating these faults. A seam resembles dispersive acoustic duct, and energy seismic source within be coupled into channel modes. Scattered waves defects recorded data analyzed produce map seam....
The end of Dennard's scaling and the looming power wall have made energy primary design goals for modern processors. Further, new applications such as cloud computing Internet Things (IoT) continue to necessitate increased performance efficiency. Manycore processors show potential in addressing some these issues. However, there is little detailed data on manycore In this work, we carefully study characteristics Piton, a 25-core open source academic processor, including voltage versus...

As Moore's Law is coming to an end, heterogeneous SoCs have become ubiquitous, improving performance and efficiency with specialized hardware. However, the addition of hardware accelerators makes data supply more challenging. Feeding becomes a bottleneck, especially for data-intensive workloads such as graph analytics, sparse linear algebra, machine learning applications. DECADES addresses this issue combination accelerators, embedded FPGA (eFPGA), its unique ''intelligent storage'' (IS)...

Embedded FPGAs (eFPGA) are increasingly being used in SoCs, enabling post-silicon hardware specialization. Existing CPU-eFPGA SoCs have three deficiencies. First, their low core count hinders efficient execution of thread-level-parallel workloads. Second, noncoherent or partially coherent integration inhibits dynamic, random memory sharing. Third, the use full-custom circuits makes proprietary eFPGAs technology-dependent, inflexible physical layout, and lacking architectural customizability.
This paper presents CIFER, the world's first opensource, fully cache-coherent, heterogeneous many-core, CPU-FPGA SoC. The 12nm, 16mm2 chip integrates four 64-bit, OS-capable, RISC-V application cores; three TinyCore clusters that each contain six 32-bit, compute cores (18 in total); and an EDA-synthesized, standard-cell-based eFPGA. CIFER enables decomposition of real-world applications tailored execution (parallelization or specialization) per decomposed task. Our evaluation shows that: 1)...
Organic thin-film transistors (OTFTs) have attracted increased attention because of the possibility to produce environmentally friendly low-cost, lightweight, flexible, and even biodegradable devices. With an increasing number complex applications being proposed for organic semiconductors, need computation horsepower also rises. However, due process characteristic differences, direct adaptation silicon-based circuit designs traditional computer architecture wisdom is not applicable.
