On the Sigma Value and Sigma Range of the Join of a Finite Number of Even Cycles of the Same Order

Let c be a vertex coloring of a simple; connected graph G that uses positive integers for colors. For a vertex v of G; the color sum of v is the sum of the colors of the neighbors of v. If no two adjacent vertices of G have the same color sum; then c is called a sigma coloring of G. The sigma chromatic number of G is the minimum number of colors required in a sigma coloring of G. Let max(c) be the largest color assigned to a vertex of G by a coloring c. The sigma value of G is the minimum value of max(c) over all sigma k−colorings c of G where k is the sigma chromatic number of G. On the other hand; the sigma range of G is the minimum value of max(c) over all sigma colorings c of G. In this paper; we determine the sigma value and the sigma range of the join of a finite number of even cycles of the same order

A usability study of De La Salle University (DLSU) website: faculty scholarly output (FSO) update

The Information Technology Center (ITC) of De La Salle University proposed to launch the new faculty scholarly output website. The faculty scholarly output website is for updating online research output in terms of journal or conference publications for each faculty. The faculty will input and edit research output information in the website. This inputted information will serve as the official research record of the faculty. A usability study was conducted to determine the usability problems and pertinent webpage design factor in the layout. This study aims to determine the common mistakes being committed in using the website and the important design factors to be considered in webpage design. Thirty people comprising of faculty, student and staff from each of the university college were gathered to do the test. The usability test made use of CAMTASIA software to record and analyze the results. The result of the study identified three usability problems: navigation, wording and inconsistencies. The design factors that need to be paid careful attention to prevent usability problems: grammar consistency and the object-action interface model

Usability testing of an academic WAP service

The Information Technology Center (ITC) of the university who is in charge of web applications development proposed to launch the faculty scholarly output website. The faculty scholarly output website is for updating online research output in terms of journal or conference publications for each faculty. The inputted information would serve as the official research record of the faculty. A usability test was conducted to determine the usability problems and pertinent webpage design factor in the layout. There were four tasks that are to be completed by the subjects. The first task is to find the link for the faculty scholarly output and add a record. the second task requires the user to view the record they just entered. the third task is to edit the inputted record and to change one of the author roles of the co-authors. the fourth task is to delete the co-author and the entry itself. the faculty will input and edit research output information in the website. This study aims to determine the common mistakes being committed in using the website and the important design factors to be considered in webpage design. Thirty people comprising of faculty, student and staff from each of the university college were gathered to do the test.
