Lithium Sulfur (Li-S) battery is generally considered as a promising technology where high energy density is required at different applications. Over the past decade, there has been an ever increasing volume of Li-S academic research spanning materials development, fundamental understanding and modelling, and application-based control algorithm development. In this study, the Li-S battery techn...

Since the introduction of the first consumer lithium ion battery (LIB) in 1991, it has become attracted considerable attention as a renewable energy source. Its demand is increasing yearly with increasing diffusion of a cell-phone and a laptop PCs, recently it is widely applied to not only small type but also middle-large type products such as hybrid vehicles. For the systematic, effective deve...

Introduction.?About eighteen months ago, we (Napier and Sen, 1940) published a preliminary paper on the treatment of kala-azar by 4 : 4'-diamidino stilbene. At the time our paper was sent to press, there were in the literature? that had arrived in this country?only two detailed reports on cases treated by this drug (Adams and Yorke, 1939; and Adler and Rachmilewitz, 1939). Since then a small sp...

We compare schematic modeling of spots and plage on the surface of cool dwarfs with Pleiades data to assess effects of magnetic activity on the strengths of the Li i and K i resonance lines in Pleiades spectra. Comprehensive Li i and K i NLTE line formation computation is combined with comparatively well-established empirical solar spot and plage stratifications for solar-like stars. For other ...

In this paper we apply the techniques of symbolic dynamics to the analysis of a labor market which shows large volatility in employment flows. In a recent paper, Bhattacharya and Bunzel [1] have found that the discrete time version of the Pissarides-Mortensen matching model can easily lead to chaotic dynamics under standard sets of parameter values. To conclude about the existence of chaotic dy...

where m is the Lebesgue measure of R, has a fixed density f∗. This fixed density gives rise to a physical measure of S, which describes the asymptotic behavior of the chaotic orbits from the statistical viewpoint [3]. Our purpose is efficient computation of such fixed densities. In his book [6], Ulam proposed a piecewise constant approximation method to calculate the fixed density f∗ and conjec...

In the past decade, there have been some studies about control methods with the purpose of either reducing “bad” chaos or introducing “good” chaos [Chen & Dong, 1998]. Due to its great potential in nontraditional applications such as those found within the context of physical, chemical, mechanical, electrical, optical, and particularly, biological and medical systems [Chen et al., 2001; Schiff ...
