This paper presents an algorithm which realizes fast search for the solutions of combinatorial optimization problems with parallel digital computers.With the standard weight matrices designed for combinatorial optimization, many iterations are required before convergence to a quasioptimal solution even when many digital processors can be used in parallel. By removing the components of the einge...

We developed an asynchronous spiking photonic neuron that forms the basic building block for hybrid analog/digital lightwave neuromorphic processing. Our approach enables completely asynchronous spiking in response to input signals while maximizing the throughput relative to synchronous approaches. Asynchronous operation is achieved by generating the spike source for the photonic neuron through...

Higher-order process calculi are calculi in which processes can be communicated. We study the expressiveness of strictly higher-order process calculi, and focus on two issues well-understood for first-order calculi but not in the higher-order setting: synchronous vs. asynchronous communication and polyadic vs. monadic communication. First, and similarly to the first-order setting, synchronous p...

Modern shared-memory multiprocessors have high and non-uniform memory access (NUMA) costs. The communication cost gradually dominates the source of parallel applications’ execution. Algorithms based on affinity, like affinity scheduling algorithm (AFS), perform better than dynamic algorithms, such as guided self-scheduling (GSS) and trapezoid selfscheduling (TSS). However, as the number of proc...

Industry 4.0 is evolving through technological advancements, leveraging information technology to enhance industry with digitalisation and intelligent activities. Whereas 5.0 the Age of Augmentation, striving concentrate on human-centricity, sustainability, resilience factories synergetic industry. The crucial enhancer for improvements accomplished by digital transformation notion ‘digital trip...

In this paper, we present an original environment, the Distributed Collaborative Design Studio (DCDS) which allows multimodal real-time remote exchanges, and which aims at re-creating remotely the conditions of co-present meetings. This environment associates a videoconference tool (supporting verbal and non-verbal communication) and an original realtime shared digital hand-drawn sketches syste...

Analog Delay Line, " has been reviewed in final form. Permission, as indicated by the signatures and dates given below, is now granted to submit final copies to the College of Graduate Studies for approval. ABSTRACT High-speed synchronous interface circuits require that the controlling clock signals be accurately aligned. A dynamic de-skew circuit can be used to ensure good clock alignment acro...

The gamma-band synchronous oscillatory activity (40}60 Hz) appears in various sensory and motor cortical areas. Because both sensory stimuli and motor responses are characterized by many analog variables, questions are raised regarding whether cortical neurons manage to transmit analog information within the gamma-oscillatory activity. Here, based on the sampling theory in digital signal proces...

Traditional ADCs (Analog-to-Digital Converters) acquire samples at regular intervals TS at a sample rate fS=1/TS and needs to adhere to the Nyquist sampling theorem, i.e., fS>2 × fB, where fB is the signal’s bandwidth [1]. Due to the periodic nature of traditional ADCs, they are sometimes referred to as synchronous ADCs [2,3]. Synchronous ADCs are characterized by a periodicity in time and equi...

Ce rapport technique peut-être repéré par auteur et par titre dans le catalogue de la Bibliothèque : High-performance clocking of IPs, within a skew budget, is becoming difficult in Deep Sub-Micron technologies. Therefore, the concept of local islands of independent clocks prevails in SoCs, which can communicate using various synchronous and asynchronous interfacing methodologies. However, asyn...
