This paper shows that the time t map of the averaged Euler equations, with Dirichlet, Neumann, and mixed boundary conditions is canonical relative to a Lie-Poisson bracket constructed via a non-smooth reduction for the corresponding diffeomorphism groups. It is also shown that the geodesic spray for Neumann and mixed boundary conditions is smooth, a result already known for Dirichlet boundary c...

Large quantities of fresh produce can be grown in the Highlands provinces of Papua New Guinea, and this produce is then marketed to a range of markets, including the coastal cities of Port Moresby and Lae. However, it is often argued that the marketing system performs poorly, and various reasons for this are cited. In this paper, the results of a study on the marketing of smallholder produce or...

In this paper, the high-dimensional sparse linear regression model is considered, where the overall number of variables is larger than the number of observations. We investigate the L1 penalized least absolute deviation method. Different from most of other methods, the L1 penalized LAD method does not need any knowledge of standard deviation of the noises or any moment assumptions of the noises...

This paper analyzes the predictive performance of standard techniques for the ‘logical analysis of data’ (LAD), within a probabilistic framework. It does so by bounding the generalization error of related polynomial threshold functions in terms of their complexity and how well they fit the training data. We also quantify the predictive accuracy in terms of the extent to which there is a large s...

In Land Assembly Districts, Professors Michael Heller and Rick Hills attempt to solve a seemingly intractable problem: how is it possible to overcome the strategic holdouts that sometimes prevent socially desirable assemblies while ensuring that these assemblies are, in fact, desirable? Private assembly relies on consensual exchange and is thus generally welfare-enhancing. But private assembly ...

technique and reformatted to display the coronaries (here LAD), (a) were compared to acquisitions performed with the new hybrid method (b). In this case, the vessel sharpness resulted visibly improved in the central and distal parts of the LAD.

This paper presents a Least Absolute Value (LAV) state estimator for power system using a new method called Recursive Least Squares (RLS). Also, a suitable model is used for state estimation of power system that includes a Unified Power Flow Controller (UPFC). The IEEE 14-bus test system is used to show the validity of the proposed algorithm in estimation of power system states as well as the s...

A simple method to invert the absolute geostrophic velocity on potential-density surfaces is developed based on McDougall’s (1988) conservation statements on potential-density surfaces and Chu’s (1995) and McDougall’s (1995) P-vector concept. This method has a capability to handle a system with diapycnal velocities and non-coincidence of potential-density and neutral surfaces. The validity of t...

In the official runs, statistics are produced using the MG (Witten, Moffat, Bell, 1994)) search engine, and the terms are in fact stems, rather than complete terms. The top 25 terms selected from the positive and negative examples are merged, to form a list with no more than 50 terms. The MG retrieval system is used (massively) to transform every judged document into a Boolean vector with one c...
