Managing Complements
نویسنده
چکیده
.......Most software companies fall short of perfection, and that’s just the way it goes. It’s routine for most software firms to slap beta on the product and ship. Most companies aren’t Apple, however. In case you missed it (and if you did, where have you been?), Apple released imperfect mapping software for the latest iPhone. The Washington Monument ended up on the wrong side of the street. Bus routes didn’t appear in many major cities. Mere glitches for most firms, but for Apple it was embarrassing. The firm has not quite learned how to do beta. Lost in the ensuing brouhaha was a fundamental economic question. To wit: is it best to own a newly invented and complementary piece of software that works with lots of other software? Even Siri doesn’t have an obvious answer to that question. Let’s consider it.

متن کاملD-Spectrum and D-Energy of Complements of Iterated Line Graphs of Regular Graphs
The D-eigenvalues {µ1,…,µp} of a graph G are the eigenvalues of its distance matrix D and form its D-spectrum. The D-energy, ED(G) of G is given by ED (G) =∑i=1p |µi|. Two non cospectral graphs with respect to D are said to be D-equi energetic if they have the same D-energy. In this paper we show that if G is an r-regular graph on p vertices with 2r ≤ p - 1, then the complements of iterated lin...
متن کاملEnergy availability in athletes.
This review updates and complements the review of energy balance and body composition in the Proceedings of the 2003 IOC Consensus Conference on Sports Nutrition. It argues that the concept of energy availability is more useful than the concept of energy balance for managing the diets of athletes. It then summarizes recent reports of the existence, aetiologies, and clinical consequences of low ...
متن کاملON THE STRUCTURE OF FINITE PSEUDO- COMPLEMENTS OF QUADRILATERALS AND THEIR EMBEDDABILITY
A pseudo-complement of a quadrilateral D of order n, n, > 3, is a non-trivial (n+l)- regular linear space with n - 3n + 3 points and n + n - 3 lines. We prove that if n > 18 and D has at least one line of size n - 1, or if n > 25 , then the set of lines of D consists of three lines of size n -1, 6(n - 2) lines of size n - 2, and n - 5n + 6 lines of size n - 3. Furthermore, if n > 21 and D...
متن کاملThe Evaluation of the Level of C3 and C4 Complements in Unstimulated Saliva of Patients with Oral Lichen Planus
Background and Objectives: Deficiency in the complement system can lead to some autoimmune diseases, such as systemic lupus erythematosus. The purpose of this study was to investigate the levels of C3 and C4 complements in unstimulated saliva of individuals with oral lichen planus (OLP) and healthy subjects. Methods: In this case-control study, 31 healthy individuals and 31 patients with OLP en...
