Logarithmic Counting Rate Meter

Counting Quantifiers, Successor Relations, and Logarithmic Space

Validity of the inexpensive Stepping Meter in counting steps in free living conditions: a pilot study.

OBJECTIVES To evaluate if inexpensive Stepping Meters are valid in counting steps in adults in free living conditions. METHODS For six days, 35 healthy volunteers wore a criterion Yamax Digiwalker and five Stepping Meters every day until all 973 pedometers had been tested. Steps were recorded daily, and the differences between counts from the Digiwalker and the Stepping Meter were expressed a...

Algorithmic Improvements in Approximate Counting for Probabilistic Inference: From Linear to Logarithmic SAT Calls

Probabilistic inference via model counting has emerged as a scalable technique with strong formal guarantees, thanks to recent advances in hashing-based approximate counting. State-of-theart hashing-based counting algorithms use an NP oracle (SAT solver in practice), such that the number of oracle invocations grows linearly in the number of variables n in the input constraint. We present a new ...

Large Area CMOS SPADs with very low Dark Counting Rate

We designed and characterized Silicon Single-Photon Avalanche Diodes (SPADs) fabricated in a high-voltage 0.35 μm CMOS technology, achieving state-of-the-art low Dark Counting Rate (DCR), very large diameter, and extended Photon Detection Efficiency (PDE) in the Near Ultraviolet. So far, different groups fabricated CMOS SPADs in scaled technologies, but with many drawbacks in active area dimens...

Front End Electronics for High Counting Rate TRD

Fast Analog Signal Processor FASP-0.1 [1, 2] is a prototype ASIC designed at NIPNE for HCR-TRD having in mind the CBM experiment at FAIR. In this contribution we report on relevant measured parameters of ASIC analog channels and a FEE based on FASP, designed and built for in-beam tests of our HCR-TRD prototypes [3]. ASIC measured parameters [4, 5] Quiescent supply current (VD = 3.3V): 30mA ±1mA...
