The system is designed to be exploited for positioning purposes in secondary railway lines where the European railway traffic management system (ERTMS) is not available. An omnidirectional antenna, cross-polarized with respect to the other two, is used for transferring positioning data among the train and intelligent poles placed along the railway, while two directional radiating elements are arranged back-to-back, to perform wagon-to-wagon communication for train integrity purposes. The omnidirectional antenna has a radiation efficiency of 97.8% and a gain of 4.2 dBi, whereas the directive ones have 79.3% and 5.4 dBi, respectively. The data communication is established by using LoRa systems, enabling low-power, long-range communication with acceptable latency for the application purpose. Due to possible adverse environmental conditions, such as presence of dust or ice, a suitable enclosure of the system is designed to be as much as possible electromagnetically transparent. The whole system has been tested both in laboratory environment and on board of the moving train, inside and outside the wagon, demonstrating the successful communication between wagons and with the poles located along the railway.

We analyze application programming interface (API) call sequences in the same way as natural language inputs. Specifically, the proposed model employs Bi-LSTM neural networks and Bayesian neural networks (BNN) for this analysis. In the first part, a Bagging-XGBoost algorithm interprets consecutive API calls as 2-gram and 3-gram strings for early-stage malware detection and feature importance analysis. Additionally, a Bi-LSTM predicts the upcoming actions of an active malware by estimating the next API call in a sequence. Two separate Bayesian Bi-LSTMs are then developed in the second part to complement the above analysis. The first architecture is for early-stage malware detection, and the other is to predict the following action of active malware. The BNN not only predicts future malware actions but also assesses the uncertainty of each prediction. It enhances the process by providing the second and third most probable predictions, increasing system reliability and effectiveness. Our unified framework demonstrates efficiency in malware detection and action prediction, marking a significant advancement in countering malware threats. The Bayesian Bi-LSTM developed for predicting the next API call has an average accuracy of 89.53%. Additionally, the accuracy of the framework for malware detection at the early stage is 96.44%, demonstrating the superior performance of the proposed framework.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"8 ","pages":"592-600"},"PeriodicalIF":2.3,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141453322","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 first configuration consists of a square patch with outer ring which exhibits two resonances at 865MHz and 2.45GHz respectively. At both these frequencies, the antenna has its main beam along the +z axis (broadside direction). Two superstrates, S3 and S4, are designed to be used separately with this antenna. Both S3 and S4, when placed above the antenna separately, shift the first resonance from 865MHz to 905MHz without affecting the 2.45GHz resonance. Placing S3 5mm above the antenna gives rise to a bi-directional radiation pattern (±z-axis) while replacing S3 with S4 generates a main beam along the -z axis (opposite broadside direction) at 905MHz. The radiation pattern remains unperturbed at 2.45GHz for both configurations. The first antenna configuration works within the European UHF-RFID band whereas the antenna + S3 and antenna + S4 configurations work within the North-American UHF-RFID band. Additionally, all three configurations also operate within the 2.45GHz WLAN band. Both the antenna-superstrate configurations have very low profiles of \u0000<inline-formula> <tex-math>$lambda _{0}$ </tex-math></inline-formula>\u0000/\u0000<inline-formula> <tex-math>$24.4~(lambda _{0} ,, {=}$ </tex-math></inline-formula>\u0000 free space wavelength at 2.45GHz).

For example, a DSM-based backscatter modulator having only two or four impedance states can generate quadrature amplitude modulation (QAM) with e.g., 64 states, or multicarrier orthogonal frequency division multiplexed (OFDM) signals having many subcarriers. This paper describes potential improvements to in-channel spectral characteristics by adding single sideband (SSB) and double sideband (DSB) noise shaping to the DSM signal path. Using numerical simulation and hardware validation, we demonstrate that noise-shaped DSM can improve the spurious-free dynamic range (SFDR) of OFDM subcarriers generated by a low-resolution two-state or four-state impedance digital-to-analog converter. The noise shaping approaches are validated using a prototype OFDM backscatter uplink based on an FPGA driving a single-pole-four-throw (SP4T) CMOS RF switch that serves as the backscatter modulator. The SSB and DSB noise shaping techniques are compared by over-the-air transmission of five-subcarrier OFDM backscatter symbols with a four-times oversampling DSM at up to 1.25 Mbps. With this approach, we find that DSB noise shaping yielded a 6.2 dB improvement in SFDR relative to SSB noise shaping, at the cost of 9.8 dB higher peak out-of-band quantization noise. These results confirm that an all-digital modulation approach with noise-shaped DSM can be used to balance in-band vs. out-of-band quantization noise and thus optimize the spectral characteristics of hardware-efficient, all-digital backscatter modulators for low-power wireless communication.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"8 ","pages":"270-276"},"PeriodicalIF":0.0,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140924688","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}

Here, a square patch is loaded on top of a short monopole antenna to improve its input impedance and radiation efficiency. Subsequently, the tag antenna is shunt-fed (using both the direct-feeding and proximity-coupled-feeding methods) to further enhance its input impedance and omnidirectionality. As a result, the antenna impedance, radiation resistance, and radiation efficiency have all been enhanced significantly, as compared with a typical short monopole antenna. A C-shaped feedline, which is to shunt-feed the tag antenna, is also introducing additional inductance to the antenna impedance for attaining good impedance matching level. Despite having a profile of not more than one hundredth of the operating wavelength, the proposed tag antenna is still able to exhibit a strong and stable omnidirectional radiation pattern when attached on a metal.

As one of the main threats to the health of the elderly, falling seriously reduces the happiness of the elderly and imposes a burden on the medical system. Therefore, the exploration of automatic fall detection systems is crucial. However, proposed fall detection systems exhibit varying degrees of shortcomings. In this paper, we propose a new fall detection method utilizing Doppler shift with RFID passive tags. The motion of the passive tag induces a Doppler shift in the reflected signal. This method is the first to use Doppler frequency shift for fall detection in RFID. Additionally, a velocity-position iteration algorithm is applied to ascertain the tag’s position and velocity over time. The combination of velocity and position for fall detection yields higher accuracy compared to individual parameters. The proposed method demonstrates the capability to differentiate between sudden and soft falls, aiding medical professionals in identifying the cause of a user’s fall. The experimental results demonstrate that the system achieves an accuracy rate of 91.7% in detecting sudden falls, and this accuracy remains at 86.8% even after incorporating soft falls into the analysis. Consequently, the proposed method proves to be an effective and reliable approach for fall detection.","PeriodicalId":73291,"journal":{"name":"IEEE journal of radio frequency identification","volume":"8 ","pages":"252-261"},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140905330","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}
