Software product lines refer to engineering techniques for creating a portfolio of similar software systems from a shared set of software assets in a controlled way. Managing variability is the key issue of software product line practice. Modelling variation points is largely addressed by a selection of linguistic constructs and modelling techniques (e.g., design pattern, macro, configuration f...

Ground settlement is often the most serious concern when tunneling under an old city with numerous historic monuments. A successful engineering design under these conditions would require getting the most out of the ground strength parameters and avoiding any weakening maneuver throughout the operation. Knowing that surface settlement is highly affected by tunneling parameters in EPB shield tun...

The concept of rectangle-of-influence (RI) drawings is old and well-studied in the area of graph drawing. A graph has such a drawing if we can assign points to its vertices such that for every edge (v, w) the supporting rectangle (i.e., the minimal closed axis-aligned rectangle R(v, w) containing v and w) contains no other points. In the original setup, the graph had to have an edge for every p...

in this paper, using the best proximity theorems for an extensionof brosowski's theorem. we obtain other results on farthest points. finally, wede ne the concept of e- farthest points. we shall prove interesting relationshipbetween the -best approximation and the e-farthest points in normed linearspaces (x; ||.||). if z in w is a e-farthest point from an x in x, then z is also a-best ...

D uring the past decade the method of functional cranial analysis has been developed in our laboratory. The basic postulates and the experimental and clinical supporting data have been published extensively elsewhere.4-“Y The orthodontic specialty recently became aware of this analytical technique, with particular interest being expressed in the derivat,i\-e concept of the Jurrctionul matrix. I...
