Abstract Conventional model-based design methods are often limited in their effectiveness by model-plant discrepancy. A solution to this problem is proposed work enhance the robustness of motion planning for systems affected parametric uncertainty. The method exploits a variational formulation form two-point boundary value (TPBVP) which achieved as constraint enforced at two boundaries. formula...

lumbar puncture (lp) is a procedure for obtaining spinal fluid from spinal meningeal spaces this can be done as a diagnostic or therapeutic procedure which can result in to a typical positional headache named as post lumbar puncture headache .this can cause a lot of discomforts for patients and makes fear from the procedure. this study designed to evaluate the effect of resting position after l...

It is commonly asserted that the standard wage equation derived from bargaining theory cannot be identified. Here, it is argued that the case for this alleged failure rests on an outmoded definition of identification. Newer concepts based on non-stationarities, cointegration and reduced rank are appropriate. An empirical example applying these concepts shows that the standard model can be deriv...

The method of differential quadrature is employed to analyze the free vibration of a cracked cantilever beam resting on elastic foundation. The beam is made of a functionally graded material and rests on a Winkler-Pasternak foundation. The crack action is simulated by a line spring model. Also, the differential quadrature method with a geometric mapping are applied to study the free vibration o...

In the present article, we will reflect on some didactic challenges and possibilities that emerge when teaching in interdisciplinary settings, and we will use and discuss the journey as a metaphor for learning. We argue that teaching in interdisciplinary studies rests on movements between different understandings, and that it gives ample opportunities for beneficial learning processes. This doe...

A recent exchange on Benatar's book Better never to have been between Doyal and Benatar discusses Benatar's bold claim that people should not be brought into existence. Here, I expand the discussion of original position that the exchange focused on. I also discuss the asymmetries, between benefit and harm and between existence and non-existence, upon which Benatar's bold claim rests. In both di...

For biographical information on Warren, see her reading in Chapter 2. Warren explains and then attacks Regan's strong animal rights position, the view that nonhuman animals have the same basic moral rights as humans. She makes two criticisms of Regan's position: It rests on an obscure concept of inherent value, and it fails to draw a sharp line between living things which have inherent value an...

Equal distribution of suffrage is given a nearly “quasi-religious” status by democrats. However, the right to vote rests on a presumption of capacity, and knowledge and competence therefore are important features of democratic arrangements. Democratic theory often assumes that, in order for (representative) democracy to work properly, the average citizen should be interested in, and pay attenti...

This operation rests on the evidence of but a single case, but so many cases of ascites are intractable to all known methods of treatment, both medical and surgical, that it seems worth while drawing attention to this new operation. Moreover, it was performed in a most intractable case, in which all other treatments had failed, and it was attended with such instantaneous relief that further pro...
