this paper studies the existence of solutions for acoupled system of nonlinear fractional differential equations. newexistence and uniqueness results are established using banach fixedpoint theorem. other existence results are obtained using schaeferand krasnoselskii fixed point theorems. some illustrative examplesare also presented.

Discrete boundary value problems have been discussed extensively in the literature; see, for example, Agarwal et al. [1], Anderson et al. [5], and Avery et al. [6], as well as the references cited therein. In [1], the authors use critical point theory to establish the existence of multiple solutions of some regular as well as singular discrete boundary value problems. Solvability of a nonlinear...

The famous Banach contraction principle (see, e.g., [1]) plays an important role in various fields of nonlinear analysis and applied mathematical analysis. Many authors investigated and established generalizations in various different directions of the Banach contraction principle in the past; see [1-22] and references therein. In 1969, Nadler [2] first proved a set-valued generalized version o...

Fingerprint matching is one of the most important problems in Fingerprint Identification System (AFIS). In this paper a new method of the reference point alignment has been presented. A new approach of reference point localization is based on so-called identification masks which have been composed on the basis of analysis of biometric characteristic of human finger. Construction of such masks h...

one of the most important problems in geodesy is the unification of height datum. generally in geodesy; there are two types of height systems, the geometrical height based on ellipsoid and the physical height based on gravity-defined surface (zhang et al, 2009).local height datum is determined according to mean sea level (msl). in regarding to mismatch of mean sea level and geoid, on the one ha...

objective: this study aimed to provide a normative study documenting how 114 five-seven year-old non-‎patient iranian children respond to the rorschach test. we compared this especial sample to ‎international normative reference values for the comprehensive system (cs).‎ method: one hundred fourteen 5- 7- year-old non-patient iranian children were recruited from public ‎schools. using five chil...

in this paper, two sets of sufficient conditions are obtained to ensure the existence and stability of a unique equilibrium point of unforced first-order fuzzy relational dynamical systems by using two different approaches which are both based on the fuzzy relational matrix of the model.in the first approach, the equilibrium point of the system is one of the centers of the related membership fu...

This paper presents a design method of the reference governor for a stabilizable linear system with input constraints. When the input has a constraint, the input saturation might happen and thus, the controller cannot work correctly. Furthermore, the output might diverge in the case of an open loop unstable system. To remedy this problem, the reference governor is proposed. The set-point contro...
