In this paper, we propose a new technique used to design a robust controller that is not as high-order and complicated as the ones designed by conventional Η∞ loop shaping method. To overcome the problem we proposed an algorithm called Genetic Algorithm (GA) based fixed-structure Η∞ loop shaping control. In the approach, GA is adopted to solve the Η∞ loop shaping design problem under a structur...
This paper considers a class of switched dynamical systems to which two periodic inputs are applicable. We derive a one-dimensional (1-D) return map and its derivative analytically for arbitrary shapes of the inputs. Based on the derivative, we introduce a slope chart that displays the relationship between the slope of the return map and that of the inputs. Applying the slope chart to a simplif...
Medulloblastoma is the most common malignant and uncontrollable childhood brain tumor. This tumor is observed in patients of all ages, reaches a peak in children between 3 and 9 years old, and it is also the most common malignant cerebellar tumor in infants. It accounts for 1% to 2% of all brain tumors in adults. By definition, medulloblastomas arise in the posterior fossa, but histologically s...

background hypervariability of hcv proteins is an important obstacle to design an efficient vaccine for hcv infection. multi-epitope vaccines containing conserved epitopes of the virus could be a promising approach for protection against hcv. objectives cellular and humoral immune responses against multi-epitope dna and peptide vaccines were evaluated in balb/c mice. materials and methods in th...
purpose : to report a case of posterior keratoconus with atypical ocular findings case report : an 8-year-old boy was referred to our clinic with the chief complaint of blurred vision in his right eye. the patient had no history prior ocular surgery of trauma. her family history was also unremarkable. comprehensive ocular examination was performed. results : the patient's best spectacle co...
optical rehabilitation of the patient with aphakia who cannot tolerate contact lenses present a therapeutic challenge. in the absence of capsular support, anterior chamber lenses have been widely used. on the other hand intraocular lens implantation of scleral sutured posterior chamber intraocular lens during penterating keratoplasty or insufficient iris support is recommended. the purpose of t...
objective : the aim of this study was to assess the amount of interdental bone in posterior areas of the mandible for placing orthodontic mini-implants to provide and control anchorage in orthodontic treatment. materials and methods : the amount of interdental bone in areas between the second premolars and first molars, first and second molars on the right and left sides of the mandible were de...
abstract background: correction of severe kyphosis is a challenging operation in spinal surgery. a two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. we describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. methods: twelve patients (six male and si...
