Abstract: Quality of weld images in with bad lighting condition and specific image color formats add constraints to existing automated weld inspection systems. Embodiments herein provide a method and system based on Domain Knowledge Infused Adaptive-Network-based Fuzzy Inference System (DKI-ANFIS) for weld quality inspection. The DKI-ANFIS inspects the quality of weld joint using domain driven quality inspection techniques. A segmentation algorithm is used to extract the weld joint in form of fractals followed by an unsupervised technique to extract useful geometrical features from the fractals. These geometrical features are used for quality index generation. A weld inspection model comprising the DKI-ANFIS is used for determining the quality of the weld joint. DKI-ANFIS modifies layers of ANFIS by infusing layer of domain knowledge to give better results even if there is a class imbalance in the data or the data is skewed or there is only a short corpus of data available.

Abstract: The present disclosure provides novel culture system and methods for culturing and propagating hESCs in a substantially undifferentiated state for several passages. The ability to grow such cells without differentiation has important applications for therapeutic uses of ES cells for treating human disorders using tissue transplantation and/or gene therapy techniques. In particular, the disclosure further relates to conditioned medium obtained from human germ lineage derived feeder cells (GLDF). The hESC lines are derived, cultured and propagated in substantially undifferentiated state using the conditioned media from GLDF cells of the disclosure. In particular, the disclosure relates to the xeno-free derivation, culture and propagation of hESCs using conditioned medium of GLDF cells obtained thereof.

Abstract: The present disclosure relates to human germ layer derived feeder cells (GLDF cells) and method of generation thereof. Further, it relates to a method for culturing and propagating human embryonic stem cells (hESCs) in a substantially undifferentiated state for several passages on the human GLDF cells. In particular, the present disclosure relates to human GLDF cells which are capable of supporting proliferation of hESCs in a substantially undifferentiated and pluripotent state for several passages.
