In this paper, we employ both qualitative analysis and numerical simulation to investigate bounded traveling waves in a general compressible hyperelastic rod. Some new bounded traveling waves are found. Their implicit expressions are obtained. Also, their planar graphs are simulated. Since they possess some properties of kink waves, we call them generalized kink waves.

This paper considers recent developments of singly-constrained entropy models which are used for predicting future zonal populations, when the models are required to satisfy given inequality constraints for the maximum zonal populations. Wilson and Batty et al have shown how ad hoc algorithms could be used to modify the usual singly-constrained gravity model, whereas recently Jefferson and Scott have used geometric programming techniques to ensure that the inequality constraints are satisfied. This work develops an approach suggested by Dacey and Norcliffe whereby the inequality constraints are incorporated into the expression for the system entropy. The entropy-maximising method and the more rigorous statistical derivation considered in the paper lead to implicit expressions for the zonal populations which can be evaluated by means of a given algorithm. The asymptotic properties of the model and the inclusion of attractiveness factors are also considered. An interesting feature of this model is that it contains as special cases Wilson's doubly-constrained model and singly-constrained model.

Rubber blocks of circular cross-section whose ends are bonded to rigid plates are studied under compression between either flat parallel surfaces or central parallel knife-edges. Implicit expressions are derived exactly in each case for the critical values of the loads at which the blocks begin to bend, based upon the classical theory of elasticity. Convenient very good approximate explicit representations are additionally deduced for these first critical loads. Some typical representative numerical data are compared and presented graphically in both situations.

In this paper, the bifurcation method of planar systems and simulation method of differential equations are employed to investigate the bounded traveling waves of the Camassa–Holm equation. Some new bounded traveling waves are found and their implicit expressions are obtained. Both qualitative and numerical results show that they possess the properties of compactons or generalized kink waves.

The subjective interpretation of probability—increasingly influential in other fields—makes probability a useful tool of historical analysis. It provides a framework that can accommodate the significant epistemic uncertainty involved in estimating historical quantities, especially (but not only) regarding periods for which we have limited data. Conceptualizing uncertainty in terms of probability distributions is a useful discipline because it forces historians to consider the degree of uncertainty as well as to identify a most-likely value. It becomes even more useful when multiple uncertain quantities are combined in a single analysis, a common occurrence in ancient history. Though it may appear a radical departure from current practice, it builds upon a probabilism that is already latent in historical reasoning. Most estimates of quantities in ancient history are implicit expressions of probability distributions, insofar as they represent the value judged to be most likely, given the available evidence. But the traditional point-estimate approach leaves historians’ beliefs about the likelihood of other possible values unclear or unexamined.

Abstract Statements on how the internal-to-external-dose (IED) relationship looks like are often based on qualitative toxicokinetic arguments. For example, the recently proposed kinetically derived maximum dose (KMD) states that the IED relationship must have an inflection point, due to saturation of underlying processes like metabolism or absorption. However, such statements lack a solid quantitative foundation. Therefore, we derived expressions for the IED relationship for a number of scenarios based on a generic compartmental model involving saturation. The scenarios included repeated or single dose, and saturable metabolism or saturable absorption. For some of these scenarios, an explicit expression for the IED relationship can be derived, for others only implicit expressions can be established, which need to be evaluated numerically. The results show that saturable processes will lead to an IED relationship that is nonlinear over the whole dose range, ie, it can be approximated by a linear relationship at the lower end, whereas the approximation will become gradually poorer with increasing doses. The finding that saturation does not lead to an inflection point in the IED relationship, as assumed in the KMD, implies that the KMD is not a valid approach for selecting the top dose in toxicological studies. An additional use of our results is that the derived explicit expressions of the IED relationship can be fitted to IED data, and, possibly, for extrapolation outside the observed dose range.

To predict a ship's behaviour, adopting either a partial or comprehensive non-linear hydrodynamic method, requires accurate information of incident wave and static pressure on any location over the instantaneous wetted hull surface. In this study an implicit formula to evaluate the non-linear hydrostatic and incident wave dynamic pressures acting on a ship travelling in linear or second-order deep water incident waves is deduced based on a wave mapping method. The accuracy and efficiency of the numerical scheme of study employing this formula is verified and validated through comparisons with a simple extrapolation (or stretching) approach, Wheeler stretching methods, and with a fifth-order Stokes' wave theory, which is assumed to embody a more complete solution. More accurate predictions of the dynamic pressure are achieved from the proposed second-order wave mapping method. However, as a practical approach, the presented second-order wave Wheeler stretching method can be considered as a reasonable approximation to the proposed wave mapping method.

In this paper, the bifurcation method of dynamical systems is employed to study the Camassa–Holm equation [Formula: see text] We investigate the periodic wave solutions of form u = φ(ξ) which satisfy φ(ξ + T) = φ(ξ), here ξ = x - ct and c, T are constants. Their six implicit expressions and two explicit expressions are obtained. We point out that when the initial values are changed, the periodic waves may become three waves, periodic cusp waves, smooth solitary waves and peakons. Our results give an explanation to the appearance of periodic cusp waves and peakons. Moreover, three sets of graphs of the implicit functions are drawn, and three sets of numerical simulations are displayed. The identity of these graphs and simulations imply the correctness of our theoretical results.

“Illegal immigration” occurs at a quite small scale in the Irish context, especially when compared to other European countries. Nevertheless, there is a significant level of discussion about “illegal immigration” in the Irish Parliament. Through the conceptual frameworks of Foucauldian thought and Critical Discourse Analysis, this paper undertakes a Topoi Analysis to examine discursive representations from the Irish Parliament (2002–2009). It concentrates upon the most common argumentation forwarded by parliamentarians – the need to control “illegal immigration” in Ireland. This argumentation is expressed through various discourses. Notably, these discourses are juxtaposed with positive representations of the “undocumented Irish” in the U.S. Overall, it is argued that negative control discourses about “illegal immigrants” in Ireland provide a number of functions: (i) the legitimization and continuation of the nation-state rationale of governance, (ii) the provision of a forum for implicit expressions of racism, and (iii) the acceptance of “justified” practices of exclusion of unwanted non-EU migrants.
