This study examines a scenario combining a prolonged solar minimum, like the historical Maunder Minimum, with the increased CO2 emissions characteristic of the industrial era. Two scenarios were developed in NCAR/CESM 2.0 implemented at LAMMOC/UFF to create simulations from 1850 to 2000, it contrasts differing radiative forcings from 1950 onward—one reflecting actual observed changes, including rising CO2 levels, and the other simulating a decrease in solar output like that during the Maunder Minimum but with continued CO2 growth. The results were validated against ERA5 data and 20th-century reanalysis. By calculating meridional averages at 30-degree latitude intervals, distinct regional impacts of the Maunder Minimum were identified. Notably the simulated Maunder Minimum reduced global warming by and even mitigated 70 % in HS in the last decade of the 20th century. However, this attenuation was lower in the HN, especially in the 30–60N region where no attenuation was observed.

Edge detection plays a significant role in assessing the capability level of the robot's vision. Accurate edge detection leads to better vision. The work in this paper was conducted by the inspiration of the biological concept of mammalian vision. That is, the retina enriches the edges in the view before passing it to the visual cortex in the brain for further processes. Although many works have been done to investigate surrounding this issue, these works are still limited in compare with that exists in retina. In this study, we investigated the main role of horizontal cells for the retina's network toward building a retina-like robot's vision technique. Experimental results show the validity of the proposed algorithm to provide accurate edges in real-time with less noise. © 2010 TSI Press.

The use of regression models in the modeling and optimization of processes is a quite powerful strategy, since it allows investigating variables that influence quality characteristics of the product or industrial process. The literature seems to be more focused on the data analysis than on providing a sequence of operational steps, which would lead to the best regression model given for the problem the researcher is confronted with. This paper is focus on the application of regression models in industrial processes, reinforcing idea that non-statistical aspects in planning and conducting modeling of data are so important as formal design and analysis. The industry case study illustrates the strong relationship of the results with incorporating presented guidelines into practice. Moreover, both case studies consolidating a fundamental advantage of regression models: modeling guided provides more knowledge about products, processes and technologies, even in unsuccessful case studies.

The matrix sensitive weaknesses of Carbon Fiber Reinforced Polymer (CFRP) laminates are usually magnified by mainstream additive manufacturing (AM) methods due to the AM-process-induced voids and defects. In this paper, a novel Magnetic Compaction Force Assisted-Additive Manufacturing (MCFA-AM) method is used to print Carbon Nanofibers (CNF) Z-threaded CFRP (i.e., ZT-CFRP) composite laminates. The MCFA-AM method utilizes a magnetic force to simultaneously support, deposit, and compact Continuous Carbon Fiber Reinforced Polymer (C-CFRP) composites in free space and quickly solidifies the CFRP part without any mold;it effectively reduces the voids. Past research proved that the zig-zag threading pattern of the CNF z-threads reinforces the interlaminar and intralaminar regions in the ZT-CFRP laminates manufactured by the traditional Out of Autoclave-Vacuum Bag Only (OOA-VBO) method, and enhances the matrix sensitive mechanical, thermal, and electrical properties. In this study, the longitudinal compressive test (ASTM D695, i.e., SACMA SRM 1R-94) was performed on the MCFA-AM printed ZT-CFRP laminate. The results were compared with unaligned CNF-modified CFRP (UA-CFRP), control CFRP, and no-pressure CFRP samples' data to investigate the impact of the CNF z-threads and MCFA-AM process on the CFRP's performance. The 0.5-bar MCFA-AM printed ZT-CFRP showed comparable longitudinal compressive strength with the 1-bar OOA-VBO cured CFRP. Copyright © 2023. Used by CAMX - The Composites and Advanced Materials Expo.

The aim of the research is to identify, evaluate, and measure the degree of importance of risks associated with healthcare inventory management that may impede the achievement of healthcare inventory objectives. An analytical hierarchy process model (AHP) was proposed to identify and hierarchize healthcare inventory risk factors. Thirteen risk factors were identified from literature review, and the AHP method was applied to rank those factors. The study found that financial risks are more severe than operational risks in healthcare inventory management. The top three risks identified were stock obsolescence, fraud committed by a provider, and insurance company disputes. These risks can have significant negative impacts on healthcare organizations and their ability to provide quality care to patients. Healthcare organizations should be aware of these risks and take steps to mitigate them. Identifying the most serious risks in HC inventory helps decision makers to make more informed data-driven decisions on which interventions are needed and where to invest more to mitigate risks and allocate resources to ensure that their inventory management processes are effective and efficient, thereby improving patient care and outcomes. Additionally, the study helps identify areas where further research is needed. © 2023 Computers and Industrial engineering. All rights reserved.

Improvements on Interpolation Techniques based on Linear programming for Constrained Control

We present some improvements on interpolation based control (IC) for linear discrete-time systems with polyhedral constraints on the control and the states variables. The plant may be uncertain, time-varying, and subject to bounded disturbances. Roughly speaking, IC approach is based on the interpolation between an inner and an outer controller. The extension presented here is twofold. On the one hand, the IC approach is extended to deal with higher order inner controllers, making it e.g. possible to incorporate integral action in a vicinity of the origin. On the other hand, this paper presents a modification that better exploits the control signal range. As with previous IC strategies, the presented method demands relatively low online computational resources, and is applicable also to uncertain plants. The benefits of the improved scheme are illustrated in some examples. © 2017

In this study, a method to modify hydrophobic PDMS (Polydimethylsiloxane) surface to be long-lasting hydrophilic surface by applying atmospheric-pressure plasma polymerization is proposed. To enhance the sustainability of the modified hydrophilic PDMS, two kinds of plasma polymerized layers were implemented on the surface of the PDMS block sequentially. The highly cross-linked hydrocarbon layer deposited by atmospheric-pressure plasma polymerization from CH 4 plays a role as a physical barrier layer (PBL) to prevent hydrophobic recovery of the hydrophilic layer deposited from TEOS (Tetraethylorthosilicate) and O2. The modified PDMS surface shows long-lasting superhydrophilic wetting property over 28 days of aging time. Copyright © (2011) by the Chemical and Biological Microsystems Society.

With the rapid development of technology, the use of social media by the public, especially among young people, is increasing. One of the social media platforms currently used by young people is the TikTok application. It is a video-based TikTok feature accompanied by music, writing, and pictures that are considered attractive, so teenagers like it to show their existence and self-disclosure. Therefore, this study aims to examine the intention of users to disclose their privacy. As the basis of the theory, this study deployed the privacy calculus theory, where the perceived benefits and perceived risks play crucial roles in the intention to disclose their privacy. The study successfully collected 369 responses. The empirical findings indicated that only the relationship between Perceived Personalization (PP) and Perceived Risk (PR) was not supported. However, all the remaining hypotheses were supported. These findings emphasize how several complicated variables influence social media users' intentions to disclose their privacy. When people feel in control of their privacy settings and see significant benefits, they are more likely to divulge personal information;nevertheless, perceived risks can greatly discourage users. © 2024 IEEE.
