abstract currently in iran, some manual methods are used for measuring spray droplet size which is very laborious and time consuming. in this paper, a software is presented based on image processing techniques, which is suitable for small object detection purpose that can be used in blob analysis of sprayer calibration and other similar applications. the algorithms have been implemented and ada...

aim and background: in recent years, experts in the field of obsessive-compulsive disorder have been trying to measure the validity and efficiency of pharmaceutical interventions. the meta-analysis evaluated the effectiveness of medication on symptoms of patients with obsessive-compulsive disorder. methods and materials: this meta-analysis was conducted on studies during the past decade in iran...

This paper contains a strain gradient theory to capture size effects in rotating nanodisks of variable thickness under thermal and mechanical loading. Material properties of nanodisks have been taken homogeneous material. The strain gradient theory and the Hamilton’s principle are employed to derive the governing equations. Due to complexity of the governing differential equation and boundary c...

Empirical links between egg size and duration of parental care in fishes have generated a considerable amount of theory concerning life history evolution. However, to date, this link has not been investigated in relation to other important life-history traits such as clutch size and body size, or while controlling for shared ancestry between species. We provide the first phylogenetically based ...

Effective gait rehabilitation is challenging, often requiring strenuous effort from a therapist, or expensive technology, or both. One rehabilitation method involves assisting the patient’s foot through a gait-like trajectory. While numerous devices have been developed to address the gait training needs of adults, these tools do not always scale well to meet the needs of a child’s smaller body ...
