The Figure of Merit

Transparent and conductive thin films of multiwalled carbon nanotubes (MWCNTs) with different lengths were prepared on glass substrates by the spin coating method. In order to reduce the MWCNTs length, they were functionalized.

Thermoelectrics (TE) is well-known as a non-smoke technology for electricity production from waste heat and for greenhouse effect reduction. Enhancing power factor (PF = S 2 , where S is Seebeck coefficient and  is electrical conductivity) and figure of merit of TE materials to achieve high-performance TE devices has attracted much scientific attention. Doping foreign elements into host bulk structure is a basic and traditional solution to modify the thermoelectric properties of materials. In this work, we use small amount of 0.5 at.

The ability discrimination of neutrons/gamma-rays of the detector was evaluated by the charge comparison (CC) method using an 252Cf source. The total efficiencies when measured on 22Na, 137Cs, 60Co and 252Cf sources were obtained 17.8%, 3.9%, 9.8% and 14.8%, respectively. The Figure of Merit (FoM) values of CC method were 0.4–1.55 for the range of energy 50–1000 keVee (keV electron equivalent).

In this paper, we present an automated, quantitative, knowledge-poor method to evaluate the randomness of a collection of documents (corpus), with respect to a number of biased partitions. The method is based on the comparison of the word frequency distribution of the target corpus to word frequency distributions from corpora built in deliberately biased ways. We apply the method to the task of building a corpus via queries to Google.

These figures derive from population studies showing the relationship of self reported levels of drinking to risk of harm. It is arbitrary which point on the risk curve is deemed to merit a warning.9-13 Other authorities have quoted weekly recommended upper limits for alcohol consumption of 21 units per week for men and 14 units per week for women.

Best-first chart parsing utilises a figure of merit (FOM) to efficiently guide a parse by first attending to those edges judged better. In the past it has usually been static; this paper will show that with some extra information, a parser can compensate for FOM flaws which otherwise slow it down. Our results are faster than the prior best by a factor of 2.5; and the speedup is won with no significant decrease in parser accuracy. length. Incomplete constituents ("edges") are stored in an agenda. The exhaustion of the agenda definitively marks the completion of the parsing algorithm, but...

For a given category, choose a small set of exemplars (or 'seed words') 2. Count co-occurrence of words and seed words within a corpus 3. Use a figure of merit based upon these counts to select new seed words 4. Return to step 2 and iterate n times 5. Use a figure of merit to rank words for category membership and o u t p u t a ranked list Our algorithm uses roughly this same generic structure, but achieves notably superior results, by changing the specifics of: what counts as co-occurrence; which figures of merit to use for...

Ambiguity in language translation is due to the presence of words in the source language with multiple non-synonymous target equivalents. A contextual analysis is required whenever a grammatical analysis fails to resolve such ambiguity. In the case of scientific and engineering literature, clues to the context can be obtained from a knowledge of the varying degrees of probability with which words occur in different fields of science.

This chapter will describe the important linear parameters which are currently used to characterise two port networks. These parameters enable manipulation and optimisation of RF circuits and lead to a number of figures of merit for devices and circuits. Commonly used figures of merit include hFE, the short circuit low frequency current gain, fT, the transition frequency at which the modulus of the short circuit current gain equals one, GUM (Maximum Unilateral Gain), the gain when the device is matched at the input and the output and the internal feedback has been assumed to be zero....

Some areas of the figure are complex enough to warrant special attention by the figure artist because they are more difficult to draw than the rest of the figure. These areas are the head, hands, and feet, and they merit special attention from the artist who really wants to master figure drawing. In this chapter we will take a closer look at each of these aspects of the figure. Hands The human hand is probably the most versatile tool ever created. It is capable of great strength, yet it can perform the most delicate operations. Its design allows people to lift, hold,...
