TRREMS procedure (transanal repair of rectocele and rectal mucosectomy with one...
Cruz, José Vinicius; Regadas, Francisco Sergio P.; Murad-Regadas, Sthela Maria; Rodrigues, Lusmar Veras; Benicio, Fernando; Leal, RogérioCONTEXT: Since anorectocele is usually associated with mucosa prolapse and/or rectal intussusceptions, it was developed a stapled surgical technique using one circular stapler. OBJECTIVE: To report the results of Transanal Repair of Rectocele and Rectal Mucosectomy with one Circular Stapler (TRREMS procedure) in the treatment of anorectocele with mucosa prolapse in a prospective multicenter trial. METHODS: It w...
Optimization of a complex flexible multibody systems with composite materials
Ambrósio, Jorge; Neto, Maria; Leal, RogérioAbstract The paper presents a general optimization methodology for flexible multibody systems which is demonstrated to find optimal layouts of fiber composite structures components. The goal of the optimization process is to minimize the structural deformation and, simultaneously, to fulfill a set of multidisciplinary constraints, by finding the optimal values for the fiber orientation of composite structures. ...
Actuator effect of a piezoelectric anisotropic plate model
Costa, Lino; Oliveira, Pedro; Figueiredo, Isabel N.; Leal, RogérioThis paper addresses the actuator e ect of a piezoelectric anisotropic plate model, depending on the location of the applied electric potentials, and for di erent clamped boundary conditions. It corresponds to integer optimization problems, whose objective functions involve the displacement of the plate. We adopt the two-dimensional piezoelectric anisotropic nonhomogeneous plate model derived in Figueiredo and ...
