Firstly, the MFR module is designed based on the multi-gradient flow residual structure of the attention mechanism, and the parallel gradient flow branches are added to the module to enrich the gradient flow of the model, so as to enhance the ability to extract the detailed information, and to improve the omission and misdetection of the small targets on the road. Secondly, the spatial pyramid network structure is improved using full-dimensional dynamic convolution to increase the sensory field of the model and improve the model’s ability to detect targets of different scales in complex backgrounds. Finally, the soft-NMS suppression algorithm is introduced to solve the problem of severe target leakage detection in obstacle-target dense regions. The experimental data show that on the BDD100K dataset, the improved algorithm improves the average accuracy mean by 7.7% compared with the original algorithm, mAP@0.5:0.9 by 5.7%, which proves that YOLOv8-AUT can better satisfy the demand for target detection in complex road scenarios of autonomous driving.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"8 ","pages":"348-356"},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140924705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study has showcased notable advancements across various standard datasets. Nevertheless, the progress in integrating language prompts faces challenges in unstructured scenarios, primarily due to the limited availability of paired data. To address this challenge, we introduce a groundbreaking language prompt set called “UnstrPrompt.” This prompt set is derived from three prominent unstructured autonomous driving datasets: IDD, ORFD, and AutoMine, collectively comprising a total of 6K language descriptions. In response to the distinctive features of unstructured scenarios, we have developed a structured approach for prompt generation, encompassing three key components: scene, road, and instance. Additionally, we provide a detailed overview of the language generation process and the validation procedures. We conduct tests on segmentation tasks, and our experiments have demonstrated that text-image fusion can improve accuracy by more than 3% on unstructured data. Additionally, our description architecture outperforms the generic urban architecture by more than 0.1%. This work holds the potential to advance various aspects such as interaction and foundational models in this scenario.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"8 ","pages":"367-375"},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140924703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The FSS structure proposed consists of periodic resistive patterns of LIG synthesized through a one-step laser photothermal process directly on the surface of a thin polyimide substrate. The structural and electrical properties of LIG were thoroughly investigated to develop an electrical model aiming at optimizing the design and absorbing properties. After that, a 12 mm thick LIG-FSS microwave absorber prototype was fabricated and tested under real conditions, demonstrating over 90% absorption in the frequency band from 1.69 to 2.91 GHz with a thickness of only 0.068 times the maximum wavelength \u0000<inline-formula> <tex-math>$(lambda _{mathrm{ max}})$ </tex-math></inline-formula>\u0000, demonstrating good agreement with the simulations and theoretical results. Additionally, we discuss the tunability of the frequency response of the absorber by adjusting accordingly the induced material’s properties.

The encoders consist of a linear chain of electric-LC (ELC) resonators etched in a dielectric substrate. Encoding is achieved by phase and frequency modulation simultaneously, namely, by considering different transverse positions and dimensions of the ELC resonators in the chain. The reader is a simple matched microstrip transmission line terminated with a matched load, and encoder reading proceeds by displacing the encoder over the reader line, at short distance, in the direction orthogonal to the line axis. When an ELC resonator lies on top of the line, the phase of the reflection coefficient at resonance depends on the distance to the input port and hence on the transverse position of the resonator in the chain (phase modulation). Moreover, the size of the resonator determines its resonance frequency (frequency modulation). This means that the reader line should be fed by as many harmonic signals as ELC resonator sizes considered, to identify the phase and the resonance frequency of the inclusion (ELC) on top of the line. In this paper, we consider 16 different transverse positions and 4 different sizes of the ELC resonators, which are read sequentially, in a time-division multiplexing scheme. Thus, 6 bits per encoder position (or row) in the chain are achieved. These encoders, with a per-unit-length density of bits of DPL = 6 bit/cm, can be applied to the implementation of synchronous near-field chipless-RFID systems with high data capacity, as well as long-range displacement sensors. In the latter case, the number of bits per encoder row can be doubled (i.e., 12 bits) by considering two chains and two readers, allowing for the discrimination of 212 (= 4096) absolute positions.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"8 ","pages":"134-144"},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140880765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antenna design was presented in the IEEE International Conference on RFID Technology and Applications (RFID-TA), held on September 4-6, 2023, Aveiro, Portugal, under the title “A durable and flexible, low-cost tag antenna design for UHF RFID wearable applications”. First, the theoretical and practical evaluation of the wristband tag antenna is conducted in four different scenarios. Next, the studied solution is benchmarked against a selection of the current commercial solutions. The proposed antenna design is mounted on a flexible and low-cost Teflon (PTFE) substrate, and it consists of a disconnected metal-substrate-metal layered structure. To produce a light and comfortable wearable device, the wristband design constraints limit the thickness to 1 mm and the width to 3 cm. The design is intended to be used in human identification and tracking applications while providing enough durability to endure for a prolonged period without significant antenna de-tuning. The proposed wristband is designed to operate in the FCC band (902-928 MHz) and it can reach distances over 3–5 meters, depending on the microchip sensitivity. The results of the experiments show that the performance of the proposed wristband design is comparable to current commercial solutions, while offering a different set of features. A discussion on the comparison between the current solutions and the proposed wristband antenna is provided in the text.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"8 ","pages":"125-133"},"PeriodicalIF":0.0,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10436413","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140880809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
