Classical retiming optimization algorithnis do not consider circuits containing multiplexers or demultiplexers driven by a clock signal l , because the associated retiming equations differ from the special classical form, which make applicable conibinatorialalgorithnisofpolynomial order. In order to provide an algorithm for multiplexer circuits it is shown here that retiming, being an integer l...

We have demonstrated the Šolc-type wavelength filters in a 52mm long periodically poled Ti diffused lithium niobate channel waveguide which has a domain period of 16.6μm. At room temperature, the center wavelength and the full-width at half maximum of the filter were about 1272.49nm and 0.23nm, respectively. The nearest side-lobe is about 7dB. New structure of optical add/drop multiplexer (OADM...

Estimating the cell loss probability in an ATM multiplexer is a key issue in network management and traac control tasks such as call admission control and bandwidth allocation. In this paper, we derive a new approximation to estimate the total and individual cell loss probabilities in an ATM multiplexer fed by a superposition of heterogeneous on-oo sources. Based on this approximation, a simple...

In this paper a model of a multimedia source is proposed in order to evaluate performance in an ATM multiplexer loaded by multimedia traffic. A multimedia arrival process is defined as the superposition of heterogeneous correlated arrival processes. To this purpose each monomedia source is modeled by an Interrupted Bernoulli Process (IBP) and the correlation among the media belonging to the sam...

In this paper we investigate the dynamic behavior of multiplexer queues for TCP traac in simple ATM networks. Our results are based on theoretical investigations which are proved by simulations. We propose a cell based queue length evaluation for TCP traac over ATM using service c ategorie UBR. In case of cell losses at the ATM multiplexer we estimate packet loss probabilities and discuss the i...

The arrayed waveguide grating (AWG) is a versatile and scalable passive photonic multiplexer that sees widespread usage. However, the necessity of array engenders large device size, gratings invariably commute finite power into undesired diffraction orders. Here, we demonstrate AWG-like functionality without or array, yielding benefits to compactness, bandwidth, efficiency. To this end, exploit...

This paper investigates the use of partial functions and fitness sharing in genetic programming. Fitness sharing is applied to populations of either partial or total functions and the results compared. Applications to two classes of problem are investigated: learning multiplexer definitions, and learning (recursive) list membership functions. In both cases, fitness sharing approaches outperform...

1-[(Anthracen-9-yl)methylene] thiosemicarbazide shows weak fluorescence due to a photo-induced electron transfer (PET) process from the thiosemicarbazide moiety to the excited anthracene. The anthracene emission can be recovered via protonation of the amine as the protonated aminomethylene as an electron-withdrawing group that suppresses the PET process. Similarly, chelation between the ligand ...

The increasing prominence of portable system and the need of limit power consumption in very high density VLSI chip have led to rapid and innovative development in low-power design during the recent years. A multiplexer, sometimes referred to as a "MUX", is a device that selects between a numbers of input signals. This paper represents the simulation of different 2:1 MUX configurations and thei...
