We consider a model of licensing of a non-drastic innovation in which the patent holder (an outside innovator) negotiates either up-front fixed fees or per-unit royalties with two firms producing horizontally differentiated brands and competing à la Cournot. We investigate how licensing schemes (fixed fee or per-unit royalty) and the number of licenses sold (exclusive licensing or complete tech...

Data caching and hoarding provide the only means to support disconnected mobile operations. In the context of mobile database applications, data cached can take the form of a materialized view. In this paper, we present a mechanism or view holder within the fixed network, whose job is to maintain versions of the views that are required by a particular mobile host. These views are very likely to...

introduction: clinical application of radiography in endodontic practice is affected by reproducibility in the orientation of the x-ray source, image receptor and object. the inability of dentists to locate intra oral films or sensors in appropriate positions in different cases can cause complications in the performance of endodontic therapy. commercially available film holder (endoray) and con...

in this paper, a novel technique on friction aided deep drawing using tapered blank holder divided into eight segments is proposed to overcome defect of friction aided deep drawing using four segments tapered blank holder technique. a taper blank holder is designed to be of two parts: stationary part with 5 degree taper angle and moving parts divided into eight tapered segments. the main functi...

suggests are either slight or problematical themselves. But given that the profession still refuses to listen, the long, sad story of the scholarly tradition in English metrics cannot be told too often. Both experienced prosodists and those who are only occasional visitors to this field will find RM a useful and enjoyable guide to what Holder calls ’the muddled kingdom of meter’ (Chapter 1), ’t...

In this paper, the effect of air turbulence intensity on the flame structure in various radii and lengths of a flame holder numerically studied. Finite volume method is used to solve the governing equations. The obtained numerical results using realizable k-ε and β-PDF models show a good agreement with the experimental data. The results show that flame holder with greater lengths yield shorter ...

PURPOSE To establish the feasibility of single-surgeon laparoscopy with application of a novel endoscope-holder device and to compare this technique with traditional assistant-driven laparoscopic camera control. MATERIALS AND METHODS Bilateral simple nephrectomies were performed in six pigs. On one side, the operating surgeon employed the "scope holder" and performed the surgery without a lap...

Aim: During minimal access surgery an assistant is controlling the laparoscope and surgeon should be free to manipulate instruments. Although the advantages of laparoscopic surgery are well documented, one disadvantage is that, for optimum performance, an experienced camera driver is required who can provide the necessary views for the operating surgeon. There are many drawbacks in human camera...
