the objective of this study is to examine the effect of mispricing on firm’s investment behavior and capital structure. it also tests the role of the level of financial constraints in the relationship between mispricing , investment and capital structure. using data of 110 firms of tehran stock exchang from 1384-1389, results indicated that mispricing has negative impact to firms investment. ho...

In this research, as the main contribution, a comprehensive study is carried out on the mathematical modeling and analysis of the inverse kinematics and dynamics of an over-constraint three translational degree-of-freedom parallel manipulator. Due to the inconsistency between the number of equations and unknowns, the problem of obtaining the constraint forces and torques of an over-constraint m...

background the impact factor (if), as the most important criterion for journal’s quality measurement, is affected by the self-citation and number of publications in each journal. objectives to find out the relationship between the number of publications and self-citations in a journal, and their correlations with if. materials and methods self-citations and impact factors of nine top gastroente...

We investigate the impact of self-interference on the performance of joint partial RAKE (PRAKE) receiver and adaptive modulation over both independent and identically distributed and independent but non-identically distributed Rayleigh fading channels in the presence of self-interference in terms of the average spectral efficiency as performance measures. Some selected results show the performa...

background: in this study, the impact of self-citation (journal and author) on impact factor of iranian english medical journals in two international citation databases, web of science (wos) and islamic world science citation center (isc), were compared by citation analysis. methods: twelve journals in wos and 26 journals in isc databases indexed between the years (2006-2009) were selected and ...

in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous  cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum ra...

SUMMARY The purpose of this study was to assess the short-term psychosocial impact of dental aesthetic improvement in adult subjects. Sixty-nine adult patients (61 females and 8 males, aged 21-59 years) requesting aesthetic dental improvement were prospectively and randomly recruited for the study in a private orthodontic office. A general interview included patient motivation and expectations ...

We search for alternative musical scales that share the main advantages of classical scales: pitch frequencies that bear simple ratios to each other, and multiple keys based on an underlying chromatic scale with tempered tuning. We conduct the search by formulating a constraint satisfaction problem that is well suited for solution by constraint programming. We find that certain 11-note scales o...

This paper presents a joint model of residential neighborhood type choice and bicycle ownership. The objective is to isolate the true causal effects of the neighborhood attributes on household bicycle ownership from spurious association due to residential self-selection effects. The joint model accounts for residential self-selection due to both observed socio-demographic characteristics and un...

Many contact tasks are more easily deened in terms of constraint equations (and therefore constraint coordinates), rather than either Cartesian or joint coordinates. Deburring and grinding are examples of two such tasks. Hybrid Impedance control has been a popular force control algorithm for these tasks. This paper gives a procedure to specify orthogonal subspaces in constraint coordinates. It ...
