the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Aims: the goal of this study was to describe the mediating role of coping strategies in relationship between difficulties in emotion regulation and internet addiction. Materials & Methods: this study was a descriptive-correlational study. the sample group in this study included 375 students, which were selected by convenience sampling from Karaj Islamic Azad University in 2018. Data were colle...

for any educational program to be successful, many factors work hand in hand. based on pervious efl studies, teachers and learners are the keys to gain achievement. granted the fact that explicit and implicit practice plays a key role in education, knowledge of it can help teachers facilitate students’ vocabulary learning. this study investigated to determine the contribution of explicit and i...

Introduction: Risky behavior refers to a set of behaviors that endanger onechr('39')s mental and physical health. The prevalence of these behaviors among Iranian students has increased.  Although, there is less attention paid to effective factors on them. Accordingly, This study aimed to investigate the relationship between Family Relationships and Risky behaviors with the mediating role of Neg...

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Background and purpose: One of the new areas of research in emotion regulation is interpersonal emotion regulation. This concept refers to individual’s willingness to share emotional states with others to reduce own negative emotions. This study was conducted to investigate the psychometric properties of Interpersonal Emotion Regulation Questionnaire (IERQ) in students. Materials and methods: ...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
