In this paper we present the characterisation of the phase noise and temporal shape of a quantum dash laser. The laser generates an optical comb with a line spacing of 24.5GHz, over a 10nm wide spectrum. The device can operate passively mode locked or actively locked to a synthesiser. The phase noise of the device has been measured and compared in both regimes. By actively mode locking the devi...

The performances of Low Gain Avalanche Diode (LGAD) sensors from a neutron irradiation campaign with fluences 0.8 × 1015, 1.5 1015 and 2.5 neq/cm2 are reported in this article. These LGAD developed by the Institute High Energy Physics, Chinese Academy Sciences Novel Device Laboratory for Granularity Timing Detector Luminosity Large Hadron Collider. timing resolution collected charge were measur...

original article background and objectives: one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf- magnetic field (mf) in substations, power plants, cities, near high voltage power lines and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf mete...

Introduction: The neural substrates of temporal processing are not still fully known. The majority of interval timing studies have dealt with this subject in the context of “Explicit timing” (computing the time intervals explicitly). The hypothesis “Implicit timing” (implicitly using temporal processing to improve function) has also proposed. This lesion study addressed explicit and implicit ti...

From our experience observing novice animators, it is clear that setting keyframe spatial values is straightforward while specifying the keyframe timing is difficult and often time consuming. This paper presents a modified approach to the keyframing paradigm, performance timing, that lets the user focus on the timing of keyframes separately from the spatial values. In performance timing, the us...

Embedded SRAMs can occupy the majority of the chip area in SOCs. The increase in process variation and aging degradation due to technology scaling can severely compromise the integrity of SRAM memory cells, hence resulting in cell failures. Enough cell failures in a memory can lead to it being rejected during initial testing, and hence decrease the manufacturing yield. Or, as a result of long-t...

Real-time embedded systems increasingly need to process and store large volumes of persistent data, requiring fast, timely and predictable storage. Traditional methods of accessing storage using general-purpose operating system-based file systems do not provide the performance and timing predictability needed. This paper firstly examines the speed and consistency of SSD operations in an embedde...
