Statistical Power Supply Dynamic Noise Prediction in Hierarchical Power Grid and Package Networks [PDF]

open access: yes, 2008
One of the most crucial high performance systems-on-chip design challenge is to front their power supply noise sufferance due to high frequencies, huge number of functional blocks and technology scaling down.

A fully digital power supply noise thermometer [PDF]

open access: yes, 2009
Power Supply Noise (PSN) is one of the main concerns in scaled technology circuits, both if performance reliability must be assured and if power supply is to be dynamically reduced for dissipation regulation.

Practical challenges in data‐driven interpolation: Dealing with noise, enforcing stability, and computing realizations

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Performance research and safety verification of compound structure air spring

open access: yesAdvances in Mechanical Engineering, 2020
To further reduce the vertical stiffness of the air spring, appropriately reduce its lateral stiffness to attenuate the transmission of vibration along the lateral and longitudinal directions, a compound structure air spring (CSAS) was designed.

Model-based design of a novel modular mounting system: Light, compact, and efficient

open access: yesAdvances in Mechanical Engineering, 2022
Two-stage mounting systems applied in ships are expected to be light in weight, compact in installation space, and efficient in vibration isolation performance at the same time, which largely increases the engineering complexity.

A general theory of phase noise in electrical oscillators [PDF]

open access: yes, 1998
A general model is introduced which is capable of making accurate, quantitative predictions about the phase noise of different types of electrical oscillators by acknowledging the true periodically time-varying nature of all oscillators.

Data‐driven performance metrics for neural network learning

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Tacticity in chiral phononic crystals

open access: yesNature Communications, 2019
Here, the authors study the influence of tacticity on the dynamic behaviour of chiral structured periodic media comprising rotational inertia elements. This opens the way towards new mechanisms for wave control by exploiting spin-spin coupling mechanism.

Axial and lateral stiffness of spherical self-balancing fiber reinforced rubber pipes under internal pressure

open access: yesScience and Engineering of Composite Materials, 2021
Fiber reinforced rubber pipes are widely used to transport fluid at locations requiring flexible connections in pipeline systems. The spherical self-balancing fiber reinforced rubber pipes with low stiffness are drawing attention because of their ...

Inhibitory “noise” [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2010
Cortical neurons in vivo may operate in high-conductance states, in which the major part of the neuron's input conductance is due to synaptic activity, sometimes several-fold larger than the resting conductance. We examine here the contribution of inhibition in such high-conductance states.
