Evaluating consumers' acceptability of laser-labeled apple fruit

Fresh produce is traditionally labeled with plastic Price LookUp (PLU) stickers that are environmental contaminants and can easily detach during handling and disrupt traceability. The CO2 laser-labeling technology (LLT), an alternate method of produce labeling, has been gaining attention. However, the performance of this technology varies by produce, and consumer perception and acceptability remain understudied. The study evaluated consumers' perception and acceptability of the laser-labeled apple fruit that were purchased locally, laser-printed with a QR code, and coated with edible wax. A consumer study (N = 75) was conducted using 1) Apple with QR-code, 2) Apple with PLU plastic sticker, and 3) non-labeled control. Respondents received randomized treatment samples and completed questionnaires. The study revealed that QR-code labels were less preferred than sticker labels and no labels. Overall liking, label liking, and purchase intent were significantly lower for QR-code labels. However, after providing information about the QR-code benefits, rankings for all labels became statistically similar. Despite 52 % of respondents preferring QR-code labels for their sustainability benefits, they were less likely to recommend them than sticker labels. Laser labeling technology has the potential for industrial application from the consumers' perspectives, and providing consumer education is crucial for its success.

"Publish First": A Rapid, GPT-4 Based Digitisation System for Small Institutes with Minimal Resources

We present a streamlined technical solution ("Publish First") designed to assist smaller, resource-constrained herbaria in rapidly publishing their specimens to the Global Biodiversity Information Facility (GBIF). Specimen data from smaller herbaria, particularly those in biodiversity-rich regions of the world, provide a valuable and often unique contribution to the global pool of biodiversity knowledge (Marsico et al. 2020). However, these institutions often face challenges not applicable to larger herbaria, including a lack of staff with technical skills, limited staff hours for digitization work, inadequate financial resources for specialized scanning equipment, cameras, lights, and imaging stands, limited (or no) access to computers and collection management software, and unreliable internet connections. Data-scarce and biodiversity rich countries are also often linguistically diverse (Gorenflo et al. 2012), and staff may not have English skills, which means pre-existing online data publication resources and guides are of limited use. The "Publish First" method we are trialing, addresses several of these issues: it drastically simplifies the publication process so technical skills are not necessary; it minimizes administrative tasks saving time; it uses simple, cheap and easily available hardware; it does not require any specialized software; and the process is so simple that there is little to no need for any written instructions. "Publish first" requires staff to attach QR code labels containing identifiers to herbarium specimen sheets, scan these sheets using a document scanner costing around €300, then drag and drop these files to an S3 bucket (a cloud container that specialises in storing files). Subsequently, these images are automatically processed through an Optical Character Recognition (OCR) service to extract text, which is then passed on to OpenAI's Generative Pre-Transformer 4 (GPT-4) Application Programming Interface (API), for standardization. The standardized data is integrated into a Darwin Core Archive file that is automatically published through GBIF's Integrated Publishing Toolkit (IPT) (GBIF 2021). The most technically challenging aspect of this project has been the standardization of OCR data to Darwin Core using the GPT-4 API, particularly in crafting precise prompts to address the inherent inconsistency and lack of reliability in these Large Language Models (LLMs). Despite this, GPT-4 outperformed our manual scraping efforts. Our choice of GPT-4 as a model was a naive one: we implemented the workflow on some pre-digitized specimens from previously published Norwegian collections, compared the published data on GBIF with GPT-4's Darwin Core standardized output, and found the results satisfactory. Moving forward, we plan to undertake more rigorous additional research to compare the effectiveness and cost-efficiency of different LLMs as Darwin Core standardization engines. We are also particularly interested in exploring the new "function calling" feature added to the GPT-4 API, as it promises to allow us to retrieve standardized data in a more consistent and structured format. This workflow is currently under trial in Tajikistan, and may possibly be used in Uzbekistan, Armenia and Italy in the near future.

An Investigation into Replacement of Washcare Labels with Cost Effective QR Code Labels

We have worked on project an investigation into replacement of wash care labels with cost effective QR code labels. In India the wash care label instructions are not mandatory but recommended by ISO 3758 standards. We need to give the wash care instruction on garment to every customer and it is essential and necessary too. We need follow the wash care instructions and it improves life cycle of garment. Normally in foreign countries gives much priority than India because they are having care instructions mandatory and it is under legal acts. India is a developing country and 2ND highest population country in the world and most of the people (around 65%) under below poverty line and lives in rural areas. But compared to India, developed country peoples are having well economic conditions and they are able to buy the washing machines and afford to clean the garments in washing factories. In India most of the peoples are wash the garments using detergent powders/bars in normal water

Optimizing Pediatric Mask Induction Fresh Gas Flow.

The environmental impact of inhaled anesthetics is a subject of increasing research. However, little attention has been paid to optimizing high-concentration volatile anesthetics during the inhalational (mask) inductions that begin most pediatric anesthetics. The performance of the GE Datex Ohmeda TEC 7 sevoflurane vaporizer was analyzed at different fresh gas flow (FGF) rates and two clinically relevant ambient temperatures. We found that an FGF rate of 5 liters per minute (LPM) is likely optimal for inhalational inductions, rapidly achieving dialed sevoflurane concentrations at the elbow of an unprimed pediatric breathing circuit while minimizing waste associated with higher FGF rates. We began educating our department regarding these findings, first with QR code labels on anesthetic workstations, then with targeted e-mails to pediatric anesthesia teams. We analyzed peak induction FGF in 100 consecutive mask inductions at our ambulatory surgery center at three different periods - baseline, post-labels, and post-emails - to assess the efficacy of these educational interventions. We also analyzed the time from induction to the start of myringotomy tube placement in a subset of these cases to determine if reducing mask induction FGF was associated with any change in the speed of induction. Our institution's median peak FGF during inhalational inductions decreased from 9.2 LPM at baseline to 8.0 LPM after labels were placed on anesthetic workstations to 4.9 LPM after targeted e-mails. There was no associated decrease in the speed of induction. Total fresh gas flow can be limited to 5 LPM during pediatric inhalational inductions, decreasing anesthetic waste and environmental impact without slowing the speed of induction. Educational labels on anesthetic workstations and direct e-mails to clinicians were effectively used in our department to enact change in this practice.

Design of Waste Management System Using QR Code for Effective Management in Wastebank

Waste management is one of the problems faced in almost every city in Indonesia. One way to manage waste is through the waste bank. The business process of a waste bank is similar to a bank, but it is processed in the form of inorganic waste that has been sorted. In general, data management in waste banks is still conventional but the others have used of web-based or mobile technology. But in this way there are still some weaknesses such as the the time needed to input the collected waste data because the data cannot be directly entered into the system. In addition it can occur inaccurately entered data. The proposed method is using the QR code for the waste management system. In this method, admin only need to scan the QR code label attached on the waste bin stored above the weighing device using a smartphone camera. With this system QR scanner application based on mobile can be synchronized automatically with anroid smartphone. Admin then input the weight of the waste that is weighed and will be stored in the database. In this way the data input process can be faster and with the use of QR code, more data can be stored.

QR Label for Handicapped Exhibition Visitors Queue Built-Up Avoidance

Most exhibitions such as in museums items are provided with printed labels that contain information of interest. A queue of visitors will be formed both to view the items and read the labels for information of interest. Visitors have limited time to read and view as a queue will built-up in due time. Handicapped visitors on wheel chair are very disadvantaged in enjoying exhibits due to the possibility of queue built-up that could cause inconvenience to other visitors. Current visitors most likely possess smartphones as communication device. Smartphones can be exploited to satisfy the need of information. QR labelling together with private cloud or network for information retrieval is presented as a viable solution. The system could cater the need of handicapped visitors. Visitors can conveniently collect information and study it at their convenience using their smartphones. Excessive queue forming can be avoided. This research is to find the position where a handicapped or any person can reliably scan the QR code label and the advisable size of label. The result is beneficial both for the exhibition organizer and the visitor. The parameters of interest are the distance and angle where a QR code label of certain can be reliably scanned.

Graphic Coding and Decoding Methods Using Relative Coordinates

There are many processes in PCB production. In order to facilitate management and problem tracing, PCB monitoring is required in each production process. The production process of PCB is very different from that of common products. Barcode, QR code or electronic label can be pasted on common products, but not on PCB. Because corrosive chemical solution is used in many PCB production processes. In order to solve this problem, a coding method based on relative coordinates and a graphic decoding method combining Hough transform and projection transformation are proposed. This method takes into account that the most commonly used NC drilling machine in PCB manufacturing enterprises. The graphic coding method uses the relative coordinates of holes drilled on the PCB. The relative coordinates of the holes centers represent the encoding information. The image decoding method uses the Hough transform and the projection transformation. First, the captured image is transformed by Hough transform, and the center coordinates of the image are detected. Secondly, the image is projective transformed by the centers of the most lateral four holes as the feature points. The distortion image is transformed into a regular image. Then, the image decoding is realized by calculating the relative coordinates of the centers. The practicability of the method and the correctness of the algorithm are verified by experiments. This method has been used in the PCB production line of an enterprise.

LANDMARKS EVALUATION WITH USE OF QR-CODE FOR POSITIONING INDOOR ENVIRONMENT

Abstract: People tend to lose their sense of direction in closed environments and the role of indoor maps is to assist the user in navigating in these spaces, through understanding the environment, identifying reference points or positioning. Among the several forms of achieving positioning in indoor environments, this research used the method based on image recognition through identification of QR-Code labels, because of their low cost, easy implementation, and because their accuracy is not affected by the environment. As such, this article presents the use of QR-Code markers affixed to possible reference points to determine user positioning in an indoor environment using a mobile device. This study seeks to discover which are the most appropriate sites for placing QR-Codes in an environment, by evaluating what reference points and what type thereof are most used in indoor environments. This study is therefore based on the hypothesis that if initial positioning is obtained only through reference points this is sufficient for users to orient themselves. Through analysis of the results obtained from navigation tasks done by users we were able to obtain data regarding elements most cited as references. The results show that people orient themselves in distinct ways in the same environment and use as their main reference points structural elements of the environment such as stairways, lifts, and decision-making points; in general structural reference points were those most used to support orientation and navigation.

Synthesizing spatiotemporally sparse smartphone sensor data for bridge modal identification

Smartphones as vibration measurement instruments form a large-scale, citizen-induced, and mobile wireless sensor network (WSN) for system identification and structural health monitoring (SHM) applications. Crowdsourcing-based SHM is possible with a decentralized system granting citizens with operational responsibility and control. Yet, citizen initiatives introduce device mobility, drastically changing SHM results due to uncertainties in the time and the space domains. This paper proposes a modal identification strategy that fuses spatiotemporally sparse SHM data collected by smartphone-based WSNs. Multichannel data sampled with the time and the space independence is used to compose the modal identification parameters such as frequencies and mode shapes. Structural response time history can be gathered by smartphone accelerometers and converted into Fourier spectra by the processor units. Timestamp, data length, energy to power conversion address temporal variation, whereas spatial uncertainties are reduced by geolocation services or determining node identity via QR code labels. Then, parameters collected from each distributed network component can be extended to global behavior to deduce modal parameters without the need of a centralized and synchronous data acquisition system. The proposed method is tested on a pedestrian bridge and compared with a conventional reference monitoring system. The results show that the spatiotemporally sparse mobile WSN data can be used to infer modal parameters despite non-overlapping sensor operation schedule.

Evaluation of the QR Code Fabric Tag System for Textile Companies in Turkey

We proposed a QR Code Fabric Tag system, which provides an online archive for the textile companies to keep detailed information about the fabrics and transactions related to them. To provide easy way to access this information, each fabric cartel used by the company should be labeled with a unique QR code label. When the QR code is scanned by a QR Code Fabric Tag mobile application, installed on a company smartphone, all the information related to the fabric will be displayed. We tested the developed system on a group of 60 volunteers, and evaluated the performance of the system using the System Usability Scale questionnaire, filled by each participant.
