Liquid crystals have proven to provide a versatile experimental and theoretical platform for studying topological objects such as vortices, skyrmions, and hopfions. In parallel, in hard condensed matter physics, the concept of topological phases and topological order has been introduced in the context of spin liquids to investigate emergent phenomena like quantum Hall effects and high-temperature superconductivity. Here, we bridge these two seemingly disparate perspectives on topology in physics. Combining experiments and simulations, we show how topological defects in liquid crystals can be used as versatile building blocks to create complex, highly degenerate topological phases, which we refer to as ‘Combinatorial Vortex Lattices’ (CVLs). CVLs exhibit extensive residual entropy and support locally stable quasi-particle excitations in the form of charge-conserving topological monopoles, which can act as mobile information carriers and be linked via Dirac strings. CLVs can be rewritten and reconfigured on demand, endowed with various symmetries, and modified through laser-induced topological surgery — an essential capability for information storage and retrieval. We demonstrate experimentally the realization, stability, and precise optical manipulation of CVLs, thus opening new avenues for understanding and technologically exploiting higher-hierarchy topology in liquid crystals and other ordered media.

Virtualization technologies are still growing bigger and faster. Despite the greatness of its advancement, the costume industry is still very accessible when it comes to real trials. Off-the-shelf stuff are inadequate details for the desired individual to assess its in-depth utility for each garment trying on for a second, including custom stuff are much harder to try out right away. To this end, 2D image-based 3D reconstruction inclusive of touchable-virtualized space is accessible easier to stuff details for mans' decision making in purchasing. We establish the overall end-to-end pipeline from reconstruction until visualization for one instance to be triable on its stuff for a moment. As an expectation, our proposed approach can bring objects into the experimental area and use them immediately without any obstacle. © 2023 IEEE.

In this paper we propose the effect of human intervention in cause effect relationships. In data mining, human intervention has effect on the prediction the results of the relationships. If we ignore human intervention out of our consideration, we cannot predict the results correctly. We found that human interventions can change the results of the cause effect relationships effectively. So in data mining, any cause effect relationship, if human intervention can involve the cause effect relationship, we need to consider what the human intervention wants. © 2010 IEEE.

One of the main factors that impede the practice of the telemedicine is not the lack of new technologies for the communication, but the lack of studies on the use of the technology already installed in the distant areas, in way to be used of a rational way. The objective of the telemedicine is to provide help to the cares with the health with quality the distant areas of the great attendance centers. Therefore, it cannot ignore the fact that these areas do not make use of point technologies for communication. Then, it is justified the need to accomplish studies that facilitate the practice of the independent telemedicine of the installed technology. Then, the objective of this work is to use as pilot an unit of remote health, contributing with a support system that allows the practice of the telemedicine using the technology of available transmission in the respective place, avoiding that the factor cost is a barrier for the telemedicine projects and can begin an improvement process in the quality of the attendance in units of distant health of the great centers of medical attendance.

Together with the technology advancement, computer Vision plays an important role in enhancing smart computing systems to help people overcome obstacles in their daily lives. One of the common troublesome problems is human memorization ability, especially memorizing things such as personal items. It is annoying for people to waste their time finding lost items manually by recall or notes. This motivates the authors to propose a solution that can help a user find an item that he or she already saw but vaguely remembers where and when it appeared in the past. The user simply provides our system a single image of that item, then the system retrieves a rank list of visual scenes that may contain the item from video recorded implicitly during user's daily activities. Our method is based on Bag-of-Words model, one of the most famous methods in image retrieval. We first conduct experiments to find the appropriate parameters and configurations of Bag-of-Words system for visual instance search. Then we perform experiments with 110 visual queries of 30 common objects in real video with 2837 shots recorded during daily activities of volunteers. Experimental results show that for all 30/30 categories of objects, our system can help users find their objects of interest just by looking into the top 10 video shots retrieved from recorded video with the balance accuracy from 50 to 80%. This demonstrates the potential use of our method to help people remind of their items in an easy and comfortable way. © 2017 IEEE.

Load Balancing is very well applied to the distribution of internet access at any point of the Wi-Fi area so that the use of limited devices can be optimal and on target. The proper use of the Greedy Algorithms when applied to an access point device is very capable in resolving excessive loading in a single resource to take the best choice at every stage in an optimum process. Access point device is also a success factor in running the optimization of the distribution of Wi-Fi access on the Access Point is strongly influenced by the parameters set. In this research, user access factor in one very high Wi-Fi area also influences the possibility of incoming access failure. For the application of the results of this study can be utilized on all access point devices that have limits, but for speed internet access remains at the capacity provided bandwidth. © Published under licence by IOP Publishing Ltd.

In the global community, countries are paying more and more attention to the monitoring and control of food safety. The food industry is investing more resources in the production chain to improve the process. Food products may be affected by disturbances or contamination during production, processing, storage, and transportation. This causes a variety of defects in the food, which can damage the quality of the food. Food defects are classified as problems with the contents and appearance, mostly changes in food substances or damage. If the food is affected by pathogenic microorganisms and deteriorates, it will also change the appearance of the food. The problematic food will bring damage to the health of customers. Through appropriate inspection mechanisms, it is possible to prevent and reduce product recalls and processing costs. As well as satisfying consumer expectations and needs. The cost savings to the food industry are substantial. To overcome this important problem, this study utilizes artificial intelligence (AI), artificial intelligent Internet of Things (AIoT), software engineering, and data analysis techniques to build a software and hardware system with an intelligent fondant inspection system. The original manual inspection mechanism is further upgraded to an intelligent inspection system. We designed the inspection machine according to the needs of the production line and designed it as a platform for self-Training. In addition to saving more manpower for manufacturers, the system will continue to grow through self-Training and tuning model functions. We hope to achieve higher inspection accuracy and contribute to food safety. © 2023 ACM.

The aim of this study was to test the correlation between a two dimensional (2D) and three dimensional (3D) biomechanical photogrammetric model, with inspiratory and expiratory lung capacities in adolescents. This was a cross sectional study, in which 40 adolescents of both genders were assessed, aged between 14 and 17 years old. Anthropometric data were collected (body mass, height and thorax length). Then, three tests were performed for forced vital capacity (FVC) in the supine position, using a spirometer. For FVC proof assessments, the volunteers were subjected to a mapping of body structures with adhesive markers and, after the test, one was selected with better respiratory performance for computational analysis of photogrammetric thoracoabdominal mobility. The results showed average values of 15.40, 61.29, 1.66 and 25.54, for age (years), body mass (kg), height (m) and thorax length (cm), respectively. The analysis found respiratory values of: 3:22 l for forced expiratory volume in one second, 3.87 l for forced vital capacity, 6.50 l/s for peak expiratory flow and 3.59 l for deep inspiration. The correlation showed better values for 3D photogrammetry as compared to 2D. The inclusion of the third dimension has been applied in order to adequate photogrammetric methodology to existing kinematics analysis tools as videogrammetry computed and plethysmography. © Springer International Publishing Switzerland 2014.
