متن کاملThe effect of covering letter personalisation in mail surveys
It is generally assumed that personalising mail survey covering letters increases the response to mail surveys. However, most of the studies that support this assumption were conducted in the 1970s, when personalisation was novel and relatively difficult to achieve. This paper reviews the evidence for the effect of personalisation on mail survey response and reports the results of a study of pe...
متن کاملDynamic Hub Covering Problem with Flexible Covering Radius
Abstract One of the basic assumptions in hub covering problems is considering the covering radius as an exogenous parameter which cannot be controlled by the decision maker. Practically and in many real world cases with a negligible increase in costs, to increase the covering radii, it is possible to save the costs of establishing additional hub nodes. Change in problem parameters during the pl...
متن کاملCovering Graphs: The Covering Problem Solved
For every fixed graph H, we determine the H-covering number of Kn, for all n > n0(H). We prove that if h is the number of edges of H, and gcd(H) = d is the greatest common divisor of the degrees of H, then there exists n0 = n0(H), such that for all n > n0, C(H,Kn) = d dn 2h dn− 1 d ee, unless d is even, n = 1 mod d and n(n− 1)/d+ 1 = 0 mod (2h/d), in which case C(H,Kn) = d ( n 2 ) h e+ 1. Our m...
متن کاملCovering Numbers in Covering-Based Rough Sets
Rough set theory provides a systematic way for rule extraction, attribute reduction and knowledge classification in information systems. Some measurements are important in rough sets. For example, information entropy, knowledge dependency are useful in attribute reduction algorithms. This paper proposes the concepts of the lower and upper covering numbers to establish measurements in covering-b...
