The process of neurosurgery is delicate and time consuming, often resulting in lower patient outcomes and survival rates. Therefore, we are implementing computer algorithms for the classification and ...segmentation of brain tumors. This aims to improve the accuracy of identifying tumor and segmentation of the brain. The automatic segmentation of the brain is based on CT (Computed tomography) data using the Desktop Image Processing System (DISOS). The DISOS system integrates modules such as preoperative planning and user guidance. Automated segmentation algorithms, including fuzzy c means clustering method, intensity thresholding, region growing, level set methods, and machine learning approaches, are employed to segment the brain structures. This system demonstrates improved accuracy, robustness, and efficiency, although a final check by a medical expert is still necessary. Additionally, our paper highlights the use of advanced algorithms and machine learning techniques to differentiate between cancerous and non-cancerous tumors using various medical imaging data. The incorporation of genetic, molecular, and clinical data further enhances the accuracy of tumor classification models. Challenges in real time robot path planning and navigation for neurosurgery are addressed, including the use of A-mode ultrasound and augmented reality systems to provide enhanced guidance during procedures. This study concludes by emphasizing the collaboration between medical professionals and computer scientists in advancing the field of computer-assisted brain tumor diagnosis and robot-assisted surgery. Our goal is not to replace humans with robots, but the collaboration between them for incredible outcomes.
A higher product diversification range with excellent physical, mechanical and chemical properties make Fiber-reinforced polymer (FRP) composite materials a prominent candidate for engineering ...applications. But, conventional manufacturing techniques always face critical issues during the development of FRP's complex and intrinsic profile. In recent years, Additive Manufacturing (AM) or 3-D printing proves itself a robust technique to produce application-specific parts of FRP composites with a higher degree of customization. In comparison to other 3D printing techniques, Stereolithography (SLA) is able to create mechanically stable objects with higher processing speed. This information paves the way for the present review article. This paper reviews the recent advancement of SLA technique to develop objects of FRP composite materials.

Development of natural language query based automatic question answering system is in huge demand these days and is a rapidly growing field. It is considered to be the most powerful application for ...answering different user queries not only on limited domains but also in multi domain environments. In this work, a natural language query based intelligible question answering system is presented that extracts relevant answers from the documents and present the answer in a pre-defined format to the user. A comparative study of the presented model with the traditional techniques is also presented.
In this paper a two stage thermoelectric cooler which has total 50 elements out of which 30 elements are on hotter side and 20 elements are on colder side, analyzed on the basis of the principles of ...thermoeconomics. Exergy destruction has been used to calculate the second law efficiency. Then the exergy has been coupled with unit cost of exergy to calculate the cost of refrigeration produced. The model has been analyzed for a particular life cycle of thermoelectric cooler (TEC) where the operating conditions change with the variation in cold side and hot side temperatures. Two cases have been considered. In first case the cold side temperature is varied with hot side temperature maintained as constant. In second case hot side temperature is varied with cold side temperature maintained as constant. The analysis shows that on the basis of thermo-economics the first case is favorable but the comparison on the basis of coefficient of performance, rate of refrigeration and second law efficiency show that the second case is favorable.
