We establish a relative spannedness for log canonical pairs, which is generalization of the basepoint-freeness varieties with log-terminal singularities by Andreatta--Wiśniewski. Moreover, we quasi-log pairs.

We give a tropical description of the counting real log curves in toric degenerations varieties. treat case genus zero and all non-superabundant higher-genus situations. The proof relies on deformation theory is version Nishinou–Siebert approach to correspondence theorem for complex curves. In dimension two, we use similar techniques study with Welschinger signs obtain new Mikhalkin’s invariants.

The data systems, policies and procedures, corporate culture, and public face of an agency or institution make up its organizational interface. This case study describes how user interfaces for the Bureau of Labor Statistics web site evolved over a 5-year period along with the larger organizational interface and how this co-evolution has influenced the institution itself. Interviews with BLS st...

A study of the “real world” Web information searching behavior of 206 college students over a 10-month period showed that, contrary to expectations, the users adopted a more passive or browsing approach to Web information searching and became more eclectic in their selection of Web hosts as they gained experience. The study used a longitudinal transaction log analysis of the URLs accessed durin...

We report findings from a chat log analysis of a support group in which 2–5 patients and one or two facilitators chatted in a virtual space; weekly sessions lasted 1.5 hrs. each, and we followed them over five years. In the virtual space, participants were represented by avatars with emotional expressions. Chat messages were analysed with a text-mining tool, exploring whether positive emotion w...

This paper focuses on developing a relatively simple method for analyzing web-logs. It also explores the challenges and benefits of web-log analysis. The study of student behavior on this site provides insights into website design and the effectiveness of this site in particular. Another benefit realized from the paper is the ease with which these concepts can be discussed with students. The pu...

In this chapter, we present the action-object pair approach as a conceptual framework for conducting transaction log analysis. We argue that there are two basic components in the interaction between the user and the system recorded in a transaction log, which are action and object. An action is a specific expression of the user. An object is a self-contained information object, the recipient of...

‎let $lambda_1,dots,lambda_n$ be positive real numbers such that‎‎$sum_{k=1}^n lambda_k=1$‎. ‎we prove that for‎‎any positive operators $a_1,a_2,cdots‎, ‎a_n$ in semifinite von‎‎neumann algebra $m$ with faithful normal trace that $t(1)

this study was carried out to determine some biological characteristics including age, growth and somatic condition of carasobarbus luteus and capoeta trutta in the turkish part of the tigris river. the examined samples of c. luteus were distributed between ii-ix years of age. the length-weigth relations of females and males were calculated as log w =-4.7314 +3.0113 log fl and log w = -4.7631 +...
