Iterative, Small-Signal L2 Stability Analysis of Nonlinear Constrained Systems
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
Examine the Effects of Students’ Social Capital Components on Entrepreneurship Intention (Evidences from: University College of Agriculture and Natural Resources, University of Tehran)
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
