g. darbo [rend. sem. math. univ. padova, 24 (1955) 84--92] used the measure of noncompactness to investigate operators whose properties can be characterized as being intermediate between those of contraction and compact operators. in this paper, we apply the darbo's fixed point theorem for solving infinite system of linear equations in some sequence spaces.

in this paper‎, ‎we show the stability of gustafson‎, ‎weidmann‎, ‎kato‎, ‎wolf‎, ‎schechter and browder essential spectrum of bounded linear operators on banach spaces which remain invariant under additive perturbations‎ ‎belonging to a broad classes of operators $u$ such $gamma(u^m)

The aim of this study was to determine the effect of knowledge management capabilities and information technology capabilities on innovative performance with the mediating role of organizational entrepreneurship, organizational learning and competitive advantage. The research method is descriptive-survey. The statistical population consists of all employees of Shimifar Iran Company, and 137 peo...

In this paper, we investigate the multiple attribute decision making (MADM) problem based on the arithmetic and geometric aggregation operators with hesitant fuzzy linguistic information. Then, motivated by the idea of traditional arithmetic operation, we have developed some aggregation operators for aggregating hesitant fuzzy linguistic information: hesitant fuzzy linguistic weighted average (...

Aggregation operators (AOs) have been studied by many schol- ars. As many AOs are proposed, there is still lacking approach to classify the categories of AO, and to select the appropriate AO within the AO candidates. In this research, each AO can be regarded as a cognitive style or individual dierence. A Cognitive Style and Aggregation Operator (CSAO) model is pro- posed to analyze the mapping ...

Background: Emergency operators are responsible for determining the nature of callers' problems, responding to them, and dispatching an appropriate rescue team. In addition, they provide instructions on cardiopulmonary resuscitation, bleeding control, airway management, and other life-saving procedures. Emergency operators are often faced with difficult situations. This study aims to highlight ...

The adoption of synchrophasor technology has increased rapidly in the past decade. Many system operators have made applications available to operators, reveal hidden operating conditions, and increase grid resiliency. development Linear State Estimation provided an innovative method solve states linearly at a faster rate, serve as backup EMS should conventional Estimator fail solve. Advanced we...

As a part of Malaysia’s tourism landscape, the homestay business has gone through various changes in dynamic industry. It was initially developed to allow tourists and visitors experience social natural heritages local people as they live their daily life. Just like any other business, is also being impacted by rapid development information communication technology (ICT) including disruptive fi...
