A multiwavelength Brillouin/Raman distributed Bragg reflector fiber laser operating in the S-band region is proposed and demonstrated. The laser uses a 7.7 km long dispersion-shifted fiber with an effective mode area of 15 μm(2) as the Brillouin and Raman gain media simultaneously. Two 1420 nm laser diodes with a combined power of 372 mW are used as pump sources, while a fiber Bragg grating wit...

A network created from so called commodity hardware can effectively and affordably be used for high performance computing. Major attraction from such networks is cost-effectiveness due to efficient utilization of existing hardware. By combining processing powers of many scattered workstations, a large computational problem can be solved within desirable time constraint, which is comparable to t...

Broadcast domination was introduced by Erwin in 2002, and it is a variant of the standard dominating set problem, such that different vertices can be assigned different domination powers. Broadcast domination assigns an integer power f(v) ≥ 0 to each vertex v of a given graph, such that every vertex of the graph is within distance f(v) from some vertex v having f(v) ≥ 1. The optimal broadcast d...

Motivated by recent results on the Waring problem for polynomial rings [FOS12] and representation of monomial as sum of powers of linear forms [CCG12], we consider the problem of presenting monomials of degree kd as sums of kth-powers of forms of degree d. We produce a general bound on the number of summands for any number of variables which we refine in the two variables case. We completely so...

The dolphin mystique. Throughout the ages, an enduring mystique has developed around dolphins. Even today some people continue to impute dolphins with mystical abilities such as extra-sensory perception and, in alternative medicine circles, special healing powers. An entire industry in ‘dolphinassisted therapy’ has been founded on the idea that dolphins have the capacity to heal illnesses throu...

Background and Objective: Multi-walled Carbon Nano Tubes (MWCNTs) as an important element of nanosciences have a remarkable absorption in the region of NIR window (650-900 nm) which can overcome the limitations of deep treatment in photothermal therapy. To disperse MWCNTs in water, it is proposed to attach carboxylated functional group (-COOH) to MWCNTs in order to increase dispersivity in wate...

Standard and anomalous transport in incompressible flow is investigated using multiscale techniques. Eddy-diffusivities emerge from the multiscale analysis through the solution of an auxiliary equation. From the latter it is derived an upper bound to eddy-diffusivities, valid for both static and time-dependent flow. The auxiliary problem is solved by a perturbative expansion in powers of the Pé...

In this chapter, I set the stage for the type identity theories given in Chapter Two and Chapter Three by assessing type identity theory of mind. There are five reasons to prefer type identity theory of mind to dualism: it has greater explanatory power; it is more respectful of philosophical and folk intuitions about the causal powers of qualia; it is simpler, it is supported by causal closure ...

In 1984 Luczynska and her colleagues' described occupational asthma in workers packing ipecacuanha tablets, and stated that this association had not previously been described. As ipecacuanha has been used as a remedy in Britain since about 1680, having been used as a traditional cure in Brazil long before that,2 this suggested a singular failure of the powers of observation of doctors over seve...
