Multi-rotor unmanned aerial vehicles (UAVs) have become common in recent years, but non-rotor UAVs are still relatively rare. This study used an aerodynamic model to replace the multi-rotor design concept and examine load bearing capabilities, specifically for delivery of medical goods by non-rotor UAV. We use static structural simulations for static analysis and fatigue analysis to investigate the capabilities of different structural materials. The simulation results combined fatigue strength verifications, structural safety factor calculations, and finite element analyses to calculate parameters like total deformation, stress ratios, and strain magnitudes to analyze structural fatigue life. The analyses indicated that the factors of safety and fatigue lifetimes of two structural materials far exceeded standard values. They can be used to optimize designs that prevent plastic deformation and breakage. Time and money are saved in the research and development process by carrying out these calculations and static analyses of physical properties before prototypes are actually built. © The Authors, published by EDP Sciences, 2017.

Welding is both as art and science and its common use is the jointing of points. Some of the welding procedures used for jointing metal pipes are Tungsten Inert Gas and Gas Metal Arc welding and in common practice plastic pipes are bonded with the use of butt-fusion welding procedure. Since 1970’s conjoint analysis was used as a way of finding out what the preference of consumers. The objective of this study is to determine the combination welding attributes that were most preferred using a conjoint analysis approach. With conjoint analysis, together with, the orthogonal design the preference for welding materials and procedures were analyzed. It showed that pipe material with 29.24% was the most preferred attribute and Nondestructive test as the least preferred with 2.66%. The result of this study may be utilized in future related reviews and could be applicable in other related mechanical systems requiring welding works. © 2024 IEEE.

This paper introduces an experimental method to detect the motion of an electrostatic Micro-Electro-mechanical systems (MEMS) resonator in aqueous media. The resonator comprises a micro cantilever beam subject to electrostatic actuation through a side electrode. A Finite Element Method (FEM) model of the resonator is developed to determine the in-plane mode shapes and their natural frequencies in order to facilitate the experimental study. The motion of the resonator lead to variations in its capacitance and induce a current. The developed experiments demonstrate that motion-induced current can be measured and analyzed to detect the motion of the resonator's higher-order modes and can be used in chemical sensing. © 2024 IEEE.

One of the most important aspects to be considered by Distribution Centers (DCs) is the improvement of the process in relation to the attributes of the service that is provided. The purpose of this article is to analyze various alternatives for the definition of a DC with the use of a method of multi-criteria support in decision making, more specifically, the Analytic Hierarchy Process (AHP) for the allocation and weighting of importance levels for structuring DCs. To further illustrate the process, a field study was conducted in a multinational company in the food sector. This enabled the identification of the best of three possible structures that were evaluated based on the criteria and sub-criteria targeted in the decision context. The results show that the cost and quality factors are primarily responsible for choosing the most appropriate alternative. © (2014) Trans Tech Publications, Switzerland.

The COVID-19 pandemic has popularized telework using video chat tools. Although video chat tools allow people to communicate each other in remote locations, psychological distance is longer than face-to-face communication, which may lead to a lack of intimacy. Previous studies have shown that interfaces combining video chat, VR, and robots with handshakes can improve the sense of closeness. However, few studies have focused on the sense of closeness in interfaces combining VR and robots. In this study, we proposed a multimodal interface combining VR and a robotic arm and verified whether shaking hands with a remote partner in VR could shorten the psychological distance compared to video chat. The results showed that the psychological distance was predominantly shorter in VR communication than in video chat communication; however, a handshake using robotic arm did not shorten the psychological distance compared to a handshake without a robotic arm. These results indicate that spatial distance is shorter in VR than in video chat and that robotic arms must be made more human-like.

Chitin is widely distributed in nature, being the main structural component of the exoskeleton of crustaceans and is non-toxic, biodegradable and biocompatible. These exoskeletons once discarded become an industrial waste creating environmental pollutant. In order to find an alternative use, the present work exploits the extraction of the chitosan from chitin that is present in the exoskeletons of shrimps Litopenaeus vannamei and crabs Ucides cordatus and transforms it into high valued products, which can help solving the environmental problem as well to provide extra income to the fishermen. One example is the manufacture of nanomembranes from chitosan for the application in medical textiles. Nanomembranes using electrospinning of chitosan solutions (7% and 5wt%) with 100:0 v/v (TFA/DCM) and 70:30 v/v (TFA/DCM) were produced. Morphological properties of chitin and chitosan were studied using SEM, DRX, and thermal properties through TG/DTG and molecular structure by FTIR analysis. TG/DTG showed thermal decomposition of chitosan samples. X-ray diffraction analysis indicated the semi-crystalline structure of chitosan, and highly crystalline structure for chitin. Morphologies of the nanomembranes were also observed from scanning electron micrographs. Results showed that the nanomembranes with 5% chitosan solutions with 70:30 v/v (TFA/DCM) showed facilitation in the formation of the nanomembranes. The nanomembranes of shrimp and crab with 5% 70:30 v/v (TFA/DCM) had higher breaking tension and breaking extension. With positive results obtained, the present work will help the authorities to organize the fishermen to have consciousness in the collection of exoskeleton waste as well as helping to have a better environment.

This papers presents a new heuristic multiobjective optimization procedure based on Kalman filtering. The novel approach is compared to the well-known Nondominated Sorting Genetic Algorithm version II with the Zitzler, Deb and Thiele test suite showing favorable results for the Kalman based solution. Further improvement on the proposed algorithm is made with respect to the learning factor, which is set to be time-dependent, improving the algorithm in most cases and diminishing the number of control parameters. The proposed multiobjective optimization algorithm is interesting due to its convergence and coverage quality, its computational complexity and few parameters to be adjusted. © 2017

The growth of micro, small and medium enterprises of fashion industry in Bandung is very rapidly and thus the industry has to face the growing competitiveness challenge. The implementation of ERP is considered to be a strategy to support sales growth, increase management ability, enhance marketing network and also strengthen the company competitiveness. In order to be effectively implemented to achieve the goals, the ERP modules requirements are necessary to be identified based on the business process in the micro, small and medium enterprises of fashion Industry. This research is conducted using case study method in eight micro, small and medium fashion enterprises in Bandung. As the references, the business process from Process Classification Framework from American Productivity Quality Centre (PCF-APQC) for Consumer Product, PCF-APQC for Retail, and business process from the previous research are used. While the ERP used as the benchmark is the integration of SAP Apparel and Footwear Solution and SAP Retail as one of the best available technology. The result advices that functionally, the ERP system for micro, small and medium fashion enterprises needs to include product design and development modules, product marketing and selling, procurement and production, human resources management, retail shop management, and finance and accounting modules. For fashion enterprises with different size, it tends to require different level of completeness of ERP module components. The bigger the size of the fashion enterprise, it needs more complete module components based on the main and additional business processes. Whilst, for nonfunctional demand, the micro, small and medium fashion industry desires ERP with the affordable price, having the drill down ability to display data related to production and selling based on the season/collection, able to do product categorization based on the various grouping criteria, the easily understood user interface, and also practical and

Recently, Japan has been facing various social issues, and to solve these problems, it is necessary to create a society where diverse people can live comfortably. To build such a society, appropriate support tailored to individuals is required, necessitating the analysis of various types of information to understand the people's needs at any given moment. In particular, analyzing non-verbal elements such as posture, facial expressions, and gestures is crucial, as these naturally indicate a person's condition. Therefore, this study focuses on human gestures, one of the non-verbal elements, and proposes a gesture recognition method using Dynamic Time Warping (DTW) and K-Means. We demonstrated that symbolic gesture recognition is possible by recording arm trajectories from skeletal measurements with an RGB-D camera. © 2024 IEEE.
