Project planning is part of project management, which is relates to the use of schedules such as Gantt charts to plan and subsequently report progress within the project environment. Initially, the project scope is defined and the appropriate methods for completing the project are determined. In this paper a new approach for the critical path analyzing a project network with random fuzzy activi...

In this paper the problem of 3D scene and object classification from depth data is addressed. In contrast to high-dimensional feature-based representation, the depth data is described in a low dimensional space. In order to remedy the curse of dimensionality problem, the depth data is described by a sparse model over a learned dictionary. Exploiting the algorithmic information theory, a new def...

    Nature is characterized by its chaotic behavior. Mathematics is considered one of the appropriate tools to achieve the best definition of possible its chaos variables and process. Classical mathematics deals with the numbers as static and meaningless, but chaos mathematics deals with it as dynamic evolutionary, and value- added. This paper attempts to introduce the transportation problem re...

Finally, there is a definition problem between monophonic and polyphonic sounds. In the case of monophonic sound, the obvious definition is to pick the lowest partial as the fundamental frequency. In the case of polyphonic sounds, resulting either from one source (e.g., a piano) or from many sources (e.g., orchestra, choir), the definition is far more difficult, and approaches close to the prob...

In Operational Research practice there are almost always alternative paths that can be followed in the modeling and problem solving process. Path dependence refers to the impact of the path on the outcome of the process. The steps of the path include, e.g. forming the problem solving team, the framing and structuring of the problem, the choice of model, the order in which the different parts of...

Enfragmo is a logic-based software system for specifying and solving combinatorial search problems. The specification language is multi-sorted first order logic, extended with arithmetic and a limited form of inductive definition. Given a specification and problem instance, Enfragmo generates a propositional formula representing the set of solutions for the instance, which it sends to a SAT sol...

“Is every definition persuasive?” If essentialist views on are rejected and a pragmatic account adopted, where defining is speech act which fixes the meaning of term, then problem arises: if meanings not fixed by essence being itself, persuasive? To address problem, we refer to Douglas Walton’s impressive intellectual heritage—specifically argumentative potential definition. In finding some non...
