A brief analysis is presented of the effect of small variations in amplitude and phase in the accelerating rf pulse in addition to the deliberate pulse shaping on the energy deviation along a bunch train and the effects of pulse-to-pulse fluctuations.

Connected automated vehicles (CAVs) could potentially be coordinated to safely attain the maximum traffic flow on roadways under dynamic traffic patterns, such as those engendered by the merger of two strings of vehicles due a lane drop. Strings of vehicles have to be shaped correctly in terms of the inter-vehicular time-gap and velocity to ensure that such operation is feasible. However, contr...

We have developed a low noise, low power charge sensitive ampli er and pulse shaping circuit. Our application is for a double-sided germanium strip detector, nominally providing 50 independent spectroscopy channels. An array of these detectors would provide signi cant improvements in imaging, spectroscopy, and sensitivity for space-based gamma-ray astronomy. The key features of these electronic...

There is no reason to accept the doctrines crafted to sustain power and privilege, or to believe that we are constrained by mysterious and unknown social laws. These are simply decisions made within institutions that are subject to human will and that must face the test of legitimacy. And if they do not meet the test, they can be replaced by other institutions that are more free and more just, ...

|We show that oversampled lter banks (FBs) offer more design freedom and less noise sensitivity than critically sampled FBs. We provide a parameterization of all synthesis FBs satisfying perfect reconstruction for a given oversampled analysis FB, and we derive bounds and expressions for the variance of the reconstruction error due to noisy subband signals. Finally, we introduce noise shaping in...

We experimentally demonstrate simultaneous pulse repetition-rate multiplication and periodic pulse-to-pulse peak-intensity control based on optimized periodic spectral line-by-line pulse shaping. Accordingly, the method allows us to generate multiplied pulse trains in which the amplitude of each single pulse in a period can be arbitrarily tailored. The technique is illustrated with the generati...

We often wonder how do we behave in a wide variety of ways. Sometimes we feel happy; sometimes sad. The equipment with which we are born – the brain, nervous system and sensory – motor system is central to the functioning of organism. Earlier, it was believed that there is some inner spirit in all of us that controls our behaviour. Today, we know that our actions and bodily movements take place...
