To establish a connection between battery health status and data features, a battery State of Health (SOH) estimation method based on data feature mining is proposed. Four features are extracted from the battery charging curve, and the grey correlation analysis is used to determine the high correlation between features and health status. The method combines a Backpropagation (BP) neural network with Genetic Algorithm (GA) for feature training and learning, enabling the estimation of battery SOH. The feasibility of the proposed method is validated using the NASA battery dataset. The results show that the battery SOH estimation method proposed in this paper outperforms the traditional BP neural network method achieving accurate estimation.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135087356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In view of this, a highly stable XOR APUF (HS-XOR APUF) circuit is proposed by studying the generation mechanism of unstable response bits and the screening characteristics of the logic gates delay signals. First, the maximum and minimum delay signals are screened with AND/OR gate to generate highly stable response bits; Then, by inserting a inverter in the APUF switch unit, the delay time of the signal is increased, and the influence of environmental factors on the comparison signal with small delay deviation is weakened; Finally, the FPGA experimental results show that the response stability of HS-XOR APUF is rarely affected by the count of XOR units, and the AND/OR gate delay signal screening structure is simple and consumes a small amount of hardware resources, which can be widely used in the fields of information security.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135087358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This considered instrumentation noise, length uncertainty, and impedance mismatch caused by variations in cross-section due to the fabrication capabilities of each manufacturing process. By reformulating the propagation constant, we obtained the attenuation per unit length and the effective relative permittivity as a function of frequencies up to 43.5GHz with 95% confidence interval.

As a result, switching losses were reduced and the efficiency was improved by approximately 4.7 % compared to the conventional method, which was confirmed on LTspice.

However, existing hardware solutions cannot provide efficient event-based DNN accelerations owing to the characteristic of event streams, which are typically in low datarate and high-dynamic range. In this letter, we present a novel hardware design that can handle event-based DNNs according to the data characteristic of event streams. Furthermore, we provide a dataflow that enables flexible DNN data encodings (including both bitmask and compressed sparse row (CSR)) based on the event data characteristic for energy saving. Comprehensive evaluations based on four famous event-based benchmarks show that the proposed design can achieve higher performance and better energy efficiency compared with representative accelerator baselines.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135088526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To avoid the bulky off-chip image-rejection filter, the Hartley transmitter structure is employed, in which frequency plan is undertaken to improve the IRR and LOFT performance, and a two-stage polyphase filter (PPF) and an in/quadrature-phase (I/Q) Gilbert mixer are utilized to improve the IRR further. With the capacitive neutralization and transformer-based series power combining techniques, a two-stage power amplifier (PA) is used to obtain high gain and output power. In the LO buffer, a flexible phase inverting cascode structure is used to achieve reliable up-sideband operation, and the inductive peaking technique and cross-coupled transistor pair are employed to promote the LO swing. Fabricated in a 65-nm CMOS process, the proposed Ku-band transmitter occupies a chip area of 0.98 mm2, and consumes 304-mW power consumption from a 1.2-V supply voltage. With measurements, over 15.8-17.9-GHz radio frequency (RF) bandwidth, the transmitter achieves an IRR and LOFT suppression ratio of 45-55 and 43-52 dBc, respectively. Moreover, it exhibits a conversion gain of 28.5 dB, an output 1-dB compression point (OP1dB) of 13.3 dBm and a saturated output power (Psat) of 16 dBm.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135492966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
