I give a short review of the relation of infrared renormalons in QCD and higher twist effects, with the emphasis on possible applications. In particular, I present estimates of renormalon-induced uncertainties in deep inelastic sum rules and explain how the renormalons can potentially be used to unravel the structure of nonperturbative effects in complicated situations and to indicate possible ...

abstractthe aims of the present research included, investigating the possible relationships between the four aspects of cultural attitudes based on the hofsted model(masculinity, power distance, uncertainity avoidance and collectivism) and the staff's creativity in the ministry of welfare and social security. therefore, a statistical sample of 150 people was chosen from the employees of th...

A logical structure of propositions associated with a physical system,which can be xperimentally tested,form in the clasical case a Boolean algebra and in a quantum mechanical case an orthomodular lattice or poset (a quantum logic). Recently new logical structures for the presence of propositions, properties,questions or events with fuzziness,uncertainity or unsharpness has been introduced: Eff...

In this article we discuss a few aspects of the space-time description of fields and particles. In section II we will show that a line is not just a collection of points and we will have to introduce one-dimensional line-intervals as fundamental geometric elements. Similar discussions are valid for area and volume-elements. In section III we will discuss the fundamental nature of fields. In sec...

Modern day hardware platforms are parallel and diverse, ranging from mobiles to data centers. Mainstream parallel applications execute in the same system competing for resources. This resource contention may lead to drastic degradation in a program’s performance. In addition, the execution environment composed of workloads and hardware resources, is dynamic and unpredictable. Efficient matching...

What happens to the entropy increase principle as the Universe evolve to form the bigcrunch singularity? What happens to the uncertainity relations along the process of gravitational collapses? What is the quantum mechanical description of a Radon atom in a rigid box when the distance of consecutive nodes and antinodes of ψ is equal to or less than the diameter of the atom? What is the position...

Our work solves the problem of inventory tracking in the retail industry using Hidden Markov Models. It has been observed that inventory records are extremely inaccurate in practice (cf. [1–4]). Reasons for this inaccuracy are item losses due to item theft, mishandling, etc. which are unaccounted. Even more important are the lost sales due to lack of items on the shelf, called stockout losses. ...

Bronchoalveolar lavage is used to obtain cells and proteins from the lower respiratory tract for diagnosis and research. Uncertainity exists about which site in the lung is sampled by the lavage fluid and what effect different lavage volumes have on recovery of the constituents of lavage fluid. Dilution of alveolar lining fluid by lavage fluid is variable and results are usually expressed as pr...

he theory of fuzzy sets was ntroduced by Zadeh [22] in 1965 as an attempt to study the vagueness and uncertainity in real world problems. A.Rosenfeld [16] applied the notion of fuzzy sets and introduced the notion of fuzzy subgroups in groups. Since then various classical algebraic systems have been fuzzified. The theory of rough sets introduced by Z.Pawlak [14] in 1982 is another independent m...

In this thesis report (based on my paper[1]), I present a path integral formalism for treatment of Quantum/Statistical fields in flat (Minkowksi) spacetime, with random potentials. The problem is to develop a mechanism to calculate observables (correlators) for fields when there is some uncertainity/randomness in the potential for the field. Random potentials which ’drive’ the field(s) live in ...
