jahanshahloo has suggested a method for the solving linear programming problems with zero-one variables‎. ‎in this paper we formulate fully fuzzy linear programming problems with zero-one variables and a method for solving these problems is presented using the ranking function and also the branch and bound method along with an example is presented.

Let A be a finite subset of Z 2. We say A tiles Z 2 with the translation set C, if any integer z ∈ Z 2 can be represented as z1 + z2, z1 ∈ A, z2 ∈ C in a unique way. In this case we call A a Z 2-tile and write A ⊕ C = Z 2. A tile A is said to be a normal Z 2-tile if there exists a periodic set C such that A ⊕ C = Z 2. We characterize all normal Z 2-tiles with prime cardinality.

We consider two infinite games, played on a countable graph G given with an integer vertex labelling. One player seeks to construct a ray (a one-way infinite path) in G, so that the ray’s labels dominate or elude domination by an integer sequence being constructed by another player. For each game, we give a structural characterization of the graphs on which one player or the other can win, prov...

The IETF has developed a one-way packet loss metric that measures the loss rate on a Poisson and Periodic probe streams between two hosts. However, the impact of packet loss on applications is, in general, sensitive not just to the average loss rate but also to the way in which packet losses are distributed in loss episodes (i.e., maximal sets of consecutively lost probe packets). This document...

This paper presents an approach to personalized web search that is based on augmenting query with additional keywords extracted from interested person’s profile. The profile reflects interested person’s interests, past searching experiences etc. It is represented by a set of weighted keywords displayed conveniently as a keyword cloud. Experiments on web search show that our search system can im...

The article introduces the basic ideas and investigates the probabilistic version of rough set theory. It relies on both classification knowledge and probabilistic knowledge in analysis of rules and attributes. Rough approximation evaluative measures and one-way and two-way inter-set dependency measures are proposed and adopted to probabilistic rule evaluation. A new probabilistic dependency me...

The paper aimed to evaluate the drape of two-piece set-in sleeves fully lined jackets developed and produced by level 300 Home Economics Education students in University Winneba. study was conducted using fifty (50) respondents conveniently sampled from two hundred seventy-one (271) students. Observation guide (assessment form) used collect data respondents. It discovered result that mean score...

the brønsted acidic ionic liquid ([bmim]hso4) catalyzed three-component synthesis of 2h-indazolo[2,1-b]phthalazine-trione derivatives at room temperature. the integrity of the ionic liquid remains reasonably unchanged when it is separated from the reaction mixture by water extraction, as it can be recycled several times without any loss of activity in each of the title syntheses. the products a...
