关键词： shopping behavior   RFID   RSS   machine learning   outlier detection   data balancing  

摘要： Analyzing customer shopping habits in physical stores is crucial for enhancing the retailer-customer relationship and increasing business revenue. However, it can be challenging to gather data on customer browsing activities in physical stores as compared to online stores. This study suggests using RFID technology on store shelves and machine learning models to analyze customer browsing activity in retail stores. The study uses RFID tags to track product movement and collects data on customer behavior using receive signal strength (RSS) of the tags. The time-domain features were then extracted from RSS data and machine learning models were utilized to classify different customer shopping activities. We proposed integration of iForest Outlier Detection, ADASYN data balancing and Multilayer Perceptron (MLP). The results indicate that the proposed model performed better than other supervised learning models, with improvements of up to 97.778% in accuracy, 98.008% in precision, 98.333% in specificity, 98.333% in recall, and 97.750% in the f1-score. Finally, we showcased the integration of this trained model into a web-based application. This result can assist managers in understanding customer preferences and aid in product placement, promotions, and customer recommendations.

关键词： Supply chain management   RFID   Product substitution   Perishables   Non-perishables  

摘要： Supply chains with either perishables or non-perishables have been well-studied as evidenced through extant published literature. Among these studies, very few consider supply chains with both perishable and non-perishable products. Since the early 2000s, RFID (Radio-Frequency IDentification) tags have been increasingly used in supply chains that deal with perishables as well as non-perishables. While there is a reasonably large amount of published literature on RFID use in supply chains, we are unaware of any that considers the dynamics of RFID-generated information in supply chains that simultaneously involve perishables substitutable by non-perishables in retail environments. We attempt to address this void. We consider the relative benefits of sensor-enabled RFID tag use in supply chains that simultaneously contain perishables substitutable by non-perishables. We also derive expressions for conditions on their dynamics through specific consideration of their pre-determined and actual expiry dates. We operationalize our analysis from the perspective of retailers and customers.

关键词： Chipless radio frequency identification (RFID)   corner reflector (CR)   millimeter-wave radar (mmWave)   radar crosssection (RCS)  

摘要： This letter presents trimmed aperture corner reflectors (CRs) for assigning angle selectivity to chipless radio frequency identification (RFID) tags. This angle selectivity can benefit the landmark use of CR-based tags by exhibiting different signals in each direction, which enables infrastructure-to-device communication with rich context. The key idea of this work is to subtract retroreflections in unwanted directions by partially trimming the aperture of CRs, allowing control over the radar crosssection (RCS) when looked at from different angles. We developed a geometric analysis based on the effective area of CRs to determine the appropriate aperture trimming for the desired angular characteristics. This method can append direction selectivity to various CR-based chipless RFID tags. We demonstrate a trimmed CR-based spatially coded chipless RFID that can present different 4-bit IDs in three different directions while maintaining a large RCS of 1.80 dBsm. The proposed method can artificially code the selective reflections in passive reflectors and is suitable for the applications requiring large detectability, such as outdoor landmarks and signs.

摘要： This paper provides a state-of-art review on healthcare-IoT infrastructure, prominently focusing on protocol standards, enabling technologies, wireless body area network (WBAN) architectures and implementation issues. Internet of Things enchains the seamless healthcare devices from an actuatesense-communicate (ASC) network in a proliferative channel in order to develop an operationally connected healthcare environment (OCHE). Sensors and actuators are the essential components of any IoT system that generates enormous data, and this data is communicated across the network concerning elementary statuses and stored in a distributed cloud platform. This paper begins by providing a brief horizontal overview of the IoT system. The enhanced technical details pertaining to healthcare scenarios such as WBAN architecture, layered healthcare IoT architecture, and enabling technologies are described in the forthcoming fragments of the paper. Authors have then provided a brief summary of the most anticipated protocol stacks and design issues that allows researchers and healthcare professionals to understand swiftly how the numerous protocols put together to attain desired functionalities without having to get through standards and RFCs. Authors have also explored recent state-of-art to identify some of the key challenges of the healthcare IoT domain and a short summary of each related research is presented. Moreover, the relation between Healthcare IoT and other disruptive technologies such as Blockchain and Big Data is being described. Finally, the authors explicated the detailed use-case scenarios to demonstrate how the numerous protocols and architectures presented in the paper could put together to attain desired healthcare services.& COPY;2023 Published by Elsevier B.V.

摘要： Electronics is adapting to the implementation of smart objects to be used in daily life, fostering the evolution of information and communication technology toward the Internet of Things (IoT). With the development of increasingly efficient wireless sensor networks (WSNs) with a reduced form factor, everyday objects are able to acquire information, exchange data, and even make decisions, thus bringing benefits to all aspects of daily life [1] . This trend is now expanding to sectors such as health care, safety at work, production process control, and many others where high reliability and new manufacturing techniques are required for the relevant electronics [2] , [3] .
