In [1] (Hybrid Conjugate Gradient Algorithm for Unconstrained Optimization J. Optimization. Theory Appl. 141 (2009) 249 - 264), an efficient hybrid conjugate gradient algorithm, the CCOMB algorithm is proposed for solving unconstrained optimization problems. However, the proof of Theorem 2.1 in [1] is incorrect due to an erroneous inequality which used to indicate the descent property for the s...

This paper presents a proof of Stirling's formula using Haar wavelets and some properties of Hilbert space, such as Parseval's identity. The present paper shows a connection between Haar wavelets and certain sequences.

For a finite group $G$ let $nu(G)$ denote the number of conjugacy classes of non-normal subgroups of $G$. We give a short proof of a theorem of Brandl, which classifies finite groups with $nu(G)=1$.

We give a proof of the generalisation of Mendes-France and Van der Poorten's recent result over an arbitrary field of positive characteristic and then by extending a result of Carlitz, we shall introduce a class of algebraically independent series.

network marketing phenomenon in which mendacious mediators are eliminated, basically is a useful matter. but the companies so-called pyramidal schemes misuse this title. in this companies there isn’t any production, consumable goods and useful work and they just constitute the pyramids in which the money belongs to persons in lower level go into the pocket of company and few people who are in t...

the discourse of the :union: of the intellect and the intelligible is one of the important philosophical issues and porphyrius and aristotle can be mentioned as among the early advocates of it, which has been common among the peripatetics. however, kandī and fārābi can be mentioned among the early muslims who brought up the issue of the :union: of the intellect and the intelligible, but ibn sīn...

introduction: applying quality management systems can be useful for the development of health care organizations standards, services, quality improvement and costs reduction. the purpose of this study is to investigate the possibility of applying quality management system iso9001/2000 in hospitals affiliated with medical sciences universities from managers' viewpoints. methods and materials: it...

Different standards of proof are applied under the common law systems and the civil law systems. The reason is that the common-law adversarial systems rely on litigating parties to produce evidence while the civil-law inquisitorial systems rely on impartial judges to produce evidence, so the collections of evidence presented to the court are largely different. This paper analyzes the adversaria...
