This paper presents the design process of a control system for an automotive assembly line. An assembly line is composed of several zones, which in turn contain several stations. All the control functions are assured by a programmable logic controller. The versatile feature is given by the fact that the assembly line can build two types of vehicles without downtime. The PLC program can switch on the fly to the logic corresponding to the type of vehicle detected. Great importance was given to safety. Additional hardware and software redundancies were used. The human-machine interface has been designed to provide operators with quick accommodation, efficient use and quick and easy navigation through the multiple levels of screens to the desired level of detail. The techniques used in this work increase the productivity and flexibility of the assembly line. Also, measures taken regarding the safety increase confidence in the system and reduce personnel injury or financial loss due to malfunctions or mishandling. © 2023 IEEE.

Synthetic polymer nanoparticles (NPs) with biomimetic properties are ideally suited for different biomedical applications such as drug delivery and direct therapy. However, bulk synthetic approaches can suffer from poor reproducibility and scalability when precise size control or multi-step procedures are required. Herein, we report an integrated microfluidic chip for the synthesis of polymer NPs. The chip could sequentially perform homopolymer synthesis and subsequent crosslinking into NPs without intermediate purification. This was made possible by fabrication of the chip with a fluorinated elastomer and incorporation of two microfluidic mixers. The first was a long channel with passive mixing features for the aqueous RAFT synthesis of stimuli-responsive polymers in ambient conditions. The polymers were then directly fed into a hydrodynamic flow focusing (HFF) junction that rapidly mixed them with a crosslinker solution to produce NPs. Compared to microfluidic systems made of PDMS or glass, our chip had better compatibility and facile fabrication. The polymers were synthesized with high monomer conversion and the NP size was found to be influenced by the flow rate ratio between the crosslinker solution and polymer solution. This allowed for the size to be predictably controlled by careful adjustment of the fluid flow rates. The size of the NPs and their stimuli-responses were studied using DLS and SEM imaging. This microfluidic chip design can potentially streamline and provide some automation for the bottom-up synthesis of polymer NPs while offering on-demand size control. © 2024 The Royal Society of Chemistry.

The gaming industry has changed since advanced technologies and hardware specifications were able to create the possibility of gaming with connective network or known as online gaming. Some communities are accepting positively, and others are contradicted. Thus, there is an urgency to know the insight from their sentiment. The present research extracts 10 thousand sentiments at social media with sentiment text analysis. The text is interpreted into six based emotions namely anger, disgust, fear, joy, sadness, and surprise. The mining analysis by lexicon valance aware dictionary and sentiment reasoner (VADER) projects the Joy emotions as the domination result with 94.74%. Positive joy expression on online gaming is revealed by extracting the sentiment analysis. In total, ten thousand data were collected from the corpus, which resulted in the happy sentiments that were experienced. © 2023 The Authors. Published by Elsevier B.V.

Biometric technologies have been widely adopted in various commercial products, ranging from security systems to personal devices, due to their exceptional reliability and user-friendliness. Among these, palmprint biometrics has gained increasing attention for its advantages, such as ease of use, a larger surface area, and the ability to capture more features compared to other biometric methods. A typical palmprint biometric system involves five key stages: (a) Image Acquisition, (b) Hand Segmentation, (c) Pattern Generation, (d) Feature Extraction, and (e) Verification/Identification. The overall success of the system depends on the effectiveness of each stage, with hand segmentation being crucial for identifying the most relevant features for accurate verification. This study aims to achieve high-accuracy biometric recognition by segmenting hands from images captured in uncontrolled environments with complex backgrounds. Accuracy (ACC), Intersection over Union (IoU), F1-Score, and Dice Coefficient are the four critical metrics used to assess the performance of segmentation techniques. The findings demonstrate that the U-Net + ViT and MA-Net + ResNet34 techniques outperform traditional auto-encoder methods in both quantitative performance metrics and visual analysis, leading to significantly improved hand segmentation for biometric systems. © 2024 IEEE.

The occurrence of natural disasters has increased fivefold over the last half century. As disasters continue to increase in frequency so have the economic costs. With each disaster event costing billions of dollars, developing countries have been left struggling to effectively prepare and recover. This study uses a State-of-the Art Matrix (SAM) analysis to explore the most common issues that affect disaster planning and response. Results from the SAM identified gaps and future research that can be done to better support disaster planning and relief in developing countries. SAM results suggest that the areas that should be considered are resilience, emergency relief funding, and policies/procedures. The results of this analysis will help community planners in these countries to develop more robust disaster planning schema and resource allocation models. © 2022 IISE Annual Conference and Expo 2022.

Escaping the patent trolls: The impact of non-practicing entity litigation on firm innovation strategies

Research Summary: Non-practicing entities (NPEs) are firms that accumulate and acquire patents but do not further develop or implement the patented inventions (known as patent trolling). NPEs seek to receive royalties or profits through out-of-court settlements in patent infringement cases. We examine how firms targeted by NPEs in NPE-initiated litigations (i.e., target firms) shift their innovation strategies and trajectories in response to heightened litigation risks. We theorize and show that after the initial lawsuit, target firms draw more upon their in-house technologies to reduce the legal ground for further lawsuits. Furthermore, nontarget firms in related technology areas shift their innovation activities away from those of target firms under high NPE litigation risks. These effects are more pronounced with higher innovation costs and under more competitive product markets. Managerial Summary: Non-practicing entities (NPEs) are known as patent trolls that accumulate and acquire patents but do not further develop or implement these patented inventions. These patent trolls aim to obtain royalties or profits through out-of-court settlements in patent infringement cases. We investigate how firms targeted by patent trolls in litigations (i.e., target firms) change their innovation strategies and trajectories to deal with increased NPE litigation risks. After the initial lawsuit, we find that these target firms use their in-house technologies more to reduce the legal ground for future lawsuits. Moreover, nontarget firms in related technology areas move their innovation activities away from those of target firms under high litigation risks. These effects are stronger when innovation costs are higher and under more competitive product markets. © 2024 The Authors. Strategic management Journal published by John Wiley & Sons Ltd.

Floating solar systems are renewable energy technology in which the solar modules are not installed on the roof or the ground-mounted but rather float on water bodies. These are some advantages, particularly in areas with limited space. Compared to conventional solar power plants, floating modules have additional advantages, such as reducing the evaporation water losses and operating more efficiently, causing the temperature of solar modules to decrease. This research aimed to investigate previous journal articles, conference proceedings, and books from ScienceDirect, Scopus, and IEEE databases. Therefore, It spans ten years, beginning in 2013 and ending in 2023. The main keywords "Floating Solar,"Floating PV,"and "Floating photovoltaics,"which were analyzed using a bibliometric program and graphs, are used to present the results of their analysis. © 2023 IEEE.

Many archaeological relics such as a wreck of an ancient ship are remains under the sea bottom and most of them are untouched because of difficulties of underwater exploration. Usual sub-bottom explorations for offshore resources such as oil and gas are carried out using seismic and sonic prospecting instruments and it is high cost and time consuming. On the other hand, archaeological relics in the relatively shallow water are explored by a sub-bottom profiler and by divers so the area which can be investigated is very limited. The authors have been developing underwater towed vehicles and autonomous underwater gliders in the previous studies. These vehicles equip various types of instruments including an OBEM (Ocean Bottom Electro-Magnetometer). They are promising instruments for marine environment survey and ocean floor resources exploration. In this report, a towed exploration system for archaeological relics exploration is proposed and the development of the vehicle including a motion controller is discussed. The vehicle is towed near the sea bottom to improve the accuracy of the measurement using a sonic prospector. The performance of the towed system and its motion control system are assessed by tank experiments and numerical simulations. © 2022 by the International Society of Offshore and Polar Engineers (ISOPE).
