A Novel Approach for Quaternion Algebra Based JSEG Color Texture Segmentation
In this work, a novel colour quantization approach has been applied to the JSEG colour texture segmentation using quaternion algebra. As a rule, the fundamental vectors of the colour space are derived by inverting the three RGB colour directions in the complex hyperplanes. In the proposed system, colour is represented as a quaternion because quaternion algebra provides a very intuitive means of working with homogeneous coordinates. This representation views a colour pixel as a point in the three-dimensional space. A novel quantization approach that makes use of projective geometry and level set methods has been produced as a consequence of the suggested model. The JSEG colour texture segmentation will use this technique. The new colour quantization approach utilises the binary quaternion moment preserving thresholding methodology, and is therefore a splintering clustering method. This method is used to segment the colour clusters found inside the RGB cube and the colour consistency throughout the spectrum and in the space are both considered. The results of the segmentation are compared with JSEG as well as with the most recent standard segmentation techniques. These comparisons show that the suggested quantization technique makes JSEG segmentation more robust
Strain field in doubly curved surface
This paper presents algorithm for development of structural and continuous curved surface into a planar and non planar (radial) shape in 3D space. The development process is modeled by application of strain in certain plane from the curved surface to its planar development. A doubly curved surface has been generated for the purpose of technical studies. Important features of the approach include formulations of the coefficients of first fundamental form, second fundamental form, Gaussian curvature and Serret Frenet curve. The approximate strain field is obtained by solving a constrained linear and nonlinear problem in algorithm
Methods of obtaining smooth surface in 2D/3D surface reconstruction
Surface reconstruction is an emergent research area in the field of computer aided design and manufacturing. There are various methods / algorithms which are working considerably well for surface reconstruction problem but we cannot say to the best of our knowledge that we got all the solutions. Missing surface can be repaired either by surface patch or by extending boundary curves. However, in both cases, surface smoothening problem arises in form of flat surface. The present paper has been tried to offer a solution to above problem which makes the curve smoother

System of crop intensification for more productive, resource-conserving, climate-resilient, and sustainable agriculture: experience with diverse crops in varying agroecologies
With continually increasing demand for food accompanied by the constraints of climate change and the availability and quality of soil and water, the world’s farmers are challenged to produce more food per hectare with less water, and with fewer agrochemical inputs if possible. The ideas and methods of the system of rice intensification which is improving irrigated rice production are now being extended/adapted to many other crops: wheat, maize, finger millet, sugarcane, tef, mustard, legumes, vegetables, and even spices. Promoting better root growth and enhancing the soil’s fertility with organic materials are being found effective means for raising the yields of many crop plants with less water, less fertilizer, reduced seeds, fewer agrochemicals, and greater climate resilience. In this article, we review what is becoming known about various farmer-centred innovations for agroecological crop management that can contribute to agricultural sustainability. These changes represent the emerging system of crop intensification, which is being increasingly applied in Asian, African, and Latin American countries. More research will be needed to verify the efficacy and impact of these innovations and to clarify their conditions and limits. But as no negative effects for human or environmental health have been identified, making these agronomic options more widely known should prompt more investigation and, to the extent justified by results, utilization of these methodologies
Blockchain technology in the health sector
Rapid development and technological advancement have brought a lot of changes in the health industry. It makes use of a variety of technologies, including the Internet of Things” IoT and “Blockchain”. These innovations are being used in a variety of applications connected to daily healthcare activities. According to the Global Blockchain Study, numerous firms in several areas, including medical, are extending, their Blockchain activities. Even though “blockchain technology” has attracted a lot of attention in the last decade, there are still many barriers to its incorporation with IoT systems[17] and use in the medical industry. Blockchain technology is used to secure healthcare-related information securely to increase cybersecurity in the healthcare sector. A mixed-method (Primary Qualitative and Secondary Quantitative) is used to collect relevant data related to Blockchain technology in Health care. 
Cervical Ectopic Pregnancy with Unsupervised Intake of Medications for Abortion: A Case Report
Cervical ectopic pregnancy is the rarest form of ectopic pregnancy, where implantation occurs in the mucosa of the endocervical canal, below the internal os. Medical abortion is a safe and effective method of termination of early intrauterine pregnancies when carried out under the supervision of trained service providers. Unfortunately, unsupervised misuse of such methods can lead to grave morbidities, especially in ectopic pregnancies. We report a case of a 29-year-old female with cervical ectopic pregnancy, with a history of self-induced medical abortion. Her assumption that her pregnancy had been terminated caused a delay in seeking treatment, which led to complications during management. Ultrasonography revealed features suggestive of cervical ectopic pregnancy and evacuation of the fetus and placenta was done using curettage, during which she had uncontrolled severe vaginal bleeding leading to need of emergency hysterectomy
