Low-Latency High-Bandwidth Circuit and System Design for Trigger Systems in High Energy Physics

The increasing luminosity in HEP (High Energy Physics) colliders demands trigger systems to be more selective. First, more information from the detector is routed to the trigger system. Second, larger parts of this information are processed together. These ...

Development of a monolithic near-field optomechanical system

Ryan Daniel Schilling

In the same year as Einstein's annus mirabilis, English engineer and physicist John Flemming patented the first rectifying diode, which he called the "Flemming valve". Einstein's work on the photoelectric effect would change our understanding of the nature ...

Resistive random access memory based multiplexers and field programmable gate arrays

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Xifan Tang, Gain Kim, Edouard Giacomin

Resistive random access memory (RRAM) based multiplexers and field programmable gate arrays (FPGAs) are provided. The RRAM-based multiplexers and FPGAs include a 4T1R programming structure to program the RRAMs. The programming structure includes two progra ...

Ultra Low Voltage Synthesizable Memories: A Trade-Off Discussion in 65 nm CMOS

Andreas Peter Burg, Pascal Andreas Meinerzhagen, Oskar Andersson

In this study, design considerations for ultra low voltage (ULV) standard-cell based memories (SCM) are presented. Trade-offs for area cost, leakage power, access time, and access energy are discussed and realized using different read logic styles, latch a ...

A Data-oriented Transaction Execution Engine and Supporting Tools

Anastasia Ailamaki, Pinar Tözün, Miguel Sérgio De Oliveira Branco, Frederick Ryan Johnson, Danica Porobic, Ippokratis Pandis, Dimitrios Karampinas

Conventional OLTP systems assign each transaction to a worker thread and that thread accesses data, depending on what the transaction dictates. This thread-to-transaction work assignment policy leads to unpredictable accesses. The unpredictability forces e ...

Fast and accurate algorithm for the simulation of NMR spectra of large spin systems

Luc Patiny, Julien Wist, Andrés Mauricio Castillo Robles

The computational cost for the simulation of NMR spectra grows exponentially with the number of nuclei. Today, the memory available to store the Hamiltonian limits the size of the system that can be studied. Modern computers enable to tackle systems contai ...

Shore-MT: A Scalable Storage Manager for the Multicore Era

Anastasia Ailamaki, Babak Falsafi, Frederick Ryan Johnson, Ippokratis Pandis

Database storage managers have long been able to efficiently handle multiple concurrent requests. Until recently, however, a computer contained only a few single-core CPUs, and therefore only a few transactions could simultaneously access the storage manag ...

Charge transport mechanisms in microcrystalline silicon

Libero Zuppiroli, Marie-Noëlle Bussac, Steven Konezny

A heterogeneous charge transport model for microcrystalline silicon based on fluctuation-induced tunneling is presented that fits the low-temperature saturation observed in dark conductivity measurements and accounts for the film microstructure. Excellent ...

ACTIVE, A PLATFORM FOR BUILDING INTELLIGENT OPERATING ROOMS

Charles Baur

Today computers are part of the standard equipment of modern surgery rooms. They assist surgeons in performing complex procedures that would not be possible otherwise. However, despite the availability of more powerful and complex computer systems, their u ...
