The relationship between corresponding upper buccal cusp distance (IBD) and Gothic arch width, inter - condylar width (ICW) and inter-upper canine distance (ICD) in an Iranian population Dr. H. Dorriz* - Dr. A.

We give a simple proof that the straightforward generalisation of clique-width to arbitrary structures can be unbounded on structures of bounded tree-width. This can be corrected by allowing fusion of elements.
We show that for every forest T the linear rank-width of T is equal to the path-width of T , and the linear clique-width of T equals the path-width of T plus two, provided that T contains a path of length three. It follows that both linear rank-width and linear clique-width of forests can be computed in linear time. Using our characterization of linear rank-width of forests, we determine the se...
The width of a subset C of the vertices of a distance-regular graph is the maximum distance which occurs between elements of C. Dually, the dual width of a subset in a cometric association scheme is the index of the “last” eigenspace in the Q-polynomial ordering to which the characteristic vector of C is not orthogonal. Elementary bounds are derived on these two new parameters. We show that any...
There are several reasons why this book might be of interest to a TEX user. First, LTEX has a prominent place in the book. Second, the book describes a very interesting offshoot of literate programming, a topic traditionally popular in the TEX community. Third, since a number of TEX users work with data analysis and statistics, R could be a useful tool for them. Since some TUGboat readers are l...
Background and Aim: Selecting the appropriate form of anterior teeth in patients without teeth is important factor in restoring the missing beauty of the patient. For this purpose, the study of natural teeth in terms of investigating the relationship between dimensions and forms and its prevalence in the Iranian community is essential. Materials and Methods: This analytic and descriptive stu...
Background and purpose: In tooth selection for dentures, the size of the tooth is really important. To estimate the size, a group of landmarks of the face have been investigated. This study evaluated the relationship between the length and width of maxillary central incisors and measurable indices of the face in patients with complete denture. Materials and methods: A descriptive-analytic cro...
Background: The hemi-hamate arthroplasty (HHA) can restore joint congruity and stability in chronic fracturedislocationsof the proximal interphalangeal joint (PIPJ). Purpose of this study was to compare the width of the distalhamate articular surface (DHAS) to the width of the base of the middle phalanges (P2) of the fingers. We hypothesizedthe dimensions of the width of the D...
The chapter covers methods for identifying islands of tractability for NP-hard combinatorial problems by exploiting suitable properties of their graphical structure. Acyclic structures are considered, as well as nearly acyclic ones identified by means of so-called structural decomposition methods. In particular, the chapter focuses on the tree decomposition method, which is the most powerful de...
