Castillo Laborde, Carla; de Wolff, Taco; Gajardo, Pedro; Lecaros, Rodrigo; Olivar Tost, Gerard; Ramírez Cabrera, Héctor Ariel (Springer, 2021)Nonpharmaceutical interventions (NPI) such as banning public events or instituting lockdowns have been widely applied around the world to control the current COVID-19 pandemic. Typically, this type of intervention is imposed ...

Gajardo, Pedro; Peña-Torres, Julio; Ramírez Cabrera, Héctor (WILEY-BLACKWELL, 2011-05)P>In the case of small pelagic fish, it seems reasonable to consider harvest functions depending nonlinearly on fishing effort and fish stock. Indeed, empirical evidence about these fish species suggests that marginal catch ...

Gajardo, Pedro; Seeger, Alberto (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-06-01)This paper deals with the asymptotic stability analysis of a discrete dynamical inclusion whose right-hand side is a convex process. We provide necessary and sufficient conditions for weak asymptotic stability, and obtain ...

Inner estimation of the eigenvalue set and exponential series solutions to differential inclusions Álvarez Daziano, Felipe; Correa Fontecilla, Rafael; Gajardo, Pedro (HELDERMANN VERLAG, 2005-11-01)We obtain inner estimations, around special eigenvalues, for the eigenvalue set of a properly nonlinear closed convex process. We also consider a differential inclusion associated with a general closed convex process and ...

Castillo Laborde, Carla; Gajardo, Pedro; Nájera De Ferrari, Manuel; Matute, Isabel; Hirmas Adauy, Macarena; Aguirre, Pablo; Ramírez Cabrera, Héctor Ariel; Ramírez, Daniel; Aguilera, Ximena (BMC, 2021)Background Syphilis, together with other sexually transmitted infections, remains a global public health problem that is far from controlled. People deprived of liberty are a vulnerable population. Control activities in ...

Correa, Rafael; Gajardo, Pedro; Thibault, Lionel (PERGAMON-ELSEVIER SCIENCE LTD, 2006-08-15)Several kinds of behaviors of extended-real-valued lower semicontinuous functions are known to be equivalent to certain appropriate conditions in terms of the Clarke subdifferential. The paper provides a systematic study ...

Gajardo, Pedro; Ramírez Cabrera, Héctor; Rodríguez, Julio C. (Springer, 2014)This paper analyzes feeding strategies in a sequential batch reactor (SBR) with the objective of reaching a given (low) substrate level as quickly as possible for a given volume of water. Inside the SBR, several species ...

Correa, Rafael; Gajardo, Pedro; Thibault, Lionel (2010)In this work we introduce for extended real valued functions, defined on a Banach space X, the concept of K directionally Lipschitzian behavior, where K is a bounded subset of X. For different types of sets K (e.g., zero, ...

Lara, Michel de; Gajardo, Pedro; Ramírez Cabrera, Héctor (Elsevier, 2011)This paper deals with the control of discrete-time dynamical, monotone both in the state and in the control, in the presence of state and control monotone constraints. A state x is said to belong to the viability kernel ...
