CPM Equalization to Compensate for ISI due to Band Limiting Channels
… constrained by the intersymbol interference (ISI) that results from band-limiting filters. We propose two approaches to the problem of equalization of band-limited CPM signals. First, our efforts are focused on shortening the channel impulse response so that we can use a low complexity MLSE …

The efficacy of incorporating the import substitution industrialisation (ISI) theory into cooperatives: a strategy to enhance rural development in the King Cetshwayo District Municipality, South Africa.
… the import substitution industrialisation (ISI) theory into cooperatives, as a strategy to enhance rural development in the King Cetshwayo district municipality, South Africa. Studies indicate that people in the rural communities of less economically developed countries (LEDCs) are faced …

The effects of changing the interstimulus interval during habituation in Caeorhaditis elegans
… role in habituation is interstimulus interval (ISI). Understanding, at a behavioural level, the effects that ISI has on habituation may provide important insights into the cellular events involved in this form of learning. The experiments in this thesis further explored the role of ISI in …

Speech Rhythm in American English: A Corpus Study
… in two different types of prosodic domains, the ISI (inter-stress interval) and the IAI (inter-accent interval). The main finding is evidence for rhythmic shortening in the domain defined in terms of lexical stress: the duration of vowels (especially stressed vowels) decreases as the size of the …

Spike Processing Circuit Design for Neuromorphic Computing
… schemes, i.e. rate encoding, latency encoding, ISI encoding, together with related hardware implementations have been discussed and analyzed. The contributions included in this dissertation can be classified into three main parts: neuron improvement, three kinds of ISI encoder design, two types …

Modeling and Analysis of the Effects of Impairments in Fiber Optic Links
… noise, and intersymbol interference (ISI). By using a Gaussian approximation, effects of the first three impairments are analyzed. It is shown that signal-dependent noise introduces an error floor to the system and the bit-error-rate is considerably degraded if a nonzero-extinction …

A systems approach to assessing the sustainability of hybrid community energy systems.
… a novel Integrated Sustainability Index (ISI) for energy systems that considers critical multidimensional sustainability criteria. The originality of this new index is that it incorporates fundamental thermodynamic, economic, and environmental constraints to combine indicators from …

An Exploration of Target Event Encoding in a Predictive Learning Task with Humans: Integrated or Separable Processing?
… experiment, subjects were trained with a single ISI and tested with multiple ISIs in a two alternative forced choice and a go/no go version of the task. In Experiment 2 subjects were presented with four cues and two targets, where two cue-target pairs were trained at a short ISI and two at a long …

Partial Symbol Detection Based Energy-Efficient Receiver for Short-Reach Optical Communication
… bits from the incoming signal and uses MSB decisions to mitigate ISI from MSB transitions. This transforms the PAM-4 eye into a partially ISI-removed PAM-2 eye, reducing the number of comparators needed for a 1-tap PAM-4 DFE implementation from 12 to 4. Simulations show the equalizer can …

Disruption of Prepulse Inhibition by Apomorphine Across Modalities
… baseline noise) at an interstimulus interval (ISI, time between the prepulse and the startle stimulus) of 100msec. In the present study, it was hypothesized that disruption of PPI by APO would also occur with a visual prepulse stimulus, and further, that a range of ISIs would provide a more …

A class of batch-iterative methods for the equalization of intersymbol interference channels
… proposed to equalize intersymbol interference (ISi) channels in a batch-iterative fashion. The iterated-decision or multipass equalizer uses symbol decisions made during the previous iteration to cancel out both precursor and postcursor ISi during the current iteration. With each successive pass …
