In this paper, we develop a new hybrid curve fitting model using fuzzy set and rough set theory. The developed method differs from classical curve fitting techniques and algorithms. For produced rule sets of model to create by using fuzzy logic technique and the membership functions of input and output functions, the range of membership functions and the relations between membership functions i...

A new approach for segmenting 3D voxel data sets is presented. It is semi-automatic and consists of two phases. First, the initial segmentation is accomplished by voxel labeling using statistical maximum likelihood estimation techniques. The novelty of the present approach is that the type probability distribution function is not required a priori. A multi-parameter distribution which includes ...

The STEP file is the “standard for exchange of product model data,” which usually used to geometric data in boundary representation (B-rep) between different computer-aided design (CAD) platforms. These can be fully utilized and integrated into a larger manufacturing organization, such as (CAM) environment computer numerical control (CNC) machining applications based on ISO 6983. 3D models 2D p...

Artificial intelligence and deep learning algorithms have become essential fields in medical science. These help doctors detect diseases early, reduce the incidence of errors, decrease time required for disease diagnosis, thereby saving human lives. Deep models are widely used Computer-Aided Diagnosis Systems (CAD) classification various diseases, including blood cancer. Early diagnosis cancer ...

This study focuses on the topology optimization of structures using a hybrid of level set method (LSM) incorporating sensitivity analysis and isogeometric analysis (IGA). First, the topology optimization problem is formulated using the LSM based on the shape gradient. The shape gradient easily handles boundary propagation with topological changes. In the LSM, the topological gradient method as ...

one of the most important parameters describing the liposomal formulation of hydroquinone is encapsulation efficacy. for the efficacy evaluation of hydroquinone trapped in liposomal structure, there is a need to first separate liposome from the matrix surrounding it. there are various separation techniques; however, in this study, the three techniques of centrifuges with and without washing and...
