    This paper provides a method to analyze the small-signal L2 gain of control-affine nonlinear systems on compact sets via iterative semi-definite programs (SDPs). First, a continuous piecewise affine (CPA) storage function and the corresponding upper bound on the L2 gain are found on a bounded, compact set's triangulation. Then, to ensure that the state does not escape this set, a (CPA) barrier function is found that is robust to small-signal inputs. Small-signal L2 stability then holds inside each sublevel set of the barrier function inside the set where the storage function was found. The bound on the inputs is also found while searching for a barrier function. The method's effectiveness is shown in a numerical example

    The main aim of this study was to investigate the relationship of students' social capital components and entrepreneurship intention. The statistical population of this study consisted of all students of University College of Agriculture and Natural Resources, University of Tehran (N= 2600) among which 155 students where accessed based on Cochran formula and through convenient sampling. Data were collected through a questionnaire face and content validity of which was approved by faculty members of Agricultural Management and Development Department of University of Tehran. Social capital was measured by four components (i.e. social participation, social coherence, social confidence and social communication). Reliability of the research instrument was measured by computing Cronbach’s alpha coefficient which ranged from 0.72 to 0.88. Path analysis technique employed to investigate the relationship of social capital components and entrepreneurial intention. Results revealed that social participation and social coherence had a direct effect on entrepreneurial intention while social confidence and social communication had an indirect effect on it
