Traditional model-based approaches rely heavily on previous experience and expert knowledge, which hinders their practicality in the industrial field. To cope with this problem, we develop a novel CNN mode called a multi-dilated fusion convolutional neural network (MF-CNN) for bearing fault diagnosis in this study. First of all, a CNN model with 1-D convolutional operations is developed to learn features directly from vibration signals. Then, a multi-dilated fusion module (MDFM) is developed to guide the CNN model to extract features from vibration signals at multiple levels. MDFM adopts dilated convolutions with different dilation rates to enlarge the receptive field. Finally, the MF-CNN architecture is built based on the above improvements. Some experiments are carried out to verify the effectiveness of the proposed MF-CNN. Experimental results suggest that MF-CNN outperforms some state-of-the-art approaches.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116442450","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 proposed circuit emulates an inductor in parallel with a negative resistor, making it applicable to the design of a sinusoidal oscillator. The proposed simulator comprises a voltage differencing differential difference amplifier (VDDDA), a resistor, and a grounded capacitor. The proposed active inductor necessitates no essential matching criteria for passive elements. The equivalent inductance and negative resistance can be controlled electronically. Moreover, the parallel RLC and negative resistance configuration-based sinusoidal oscillator is designed as an example of its application. The oscillation frequency and condition are adjusted orthogonally. The performance of the proposed simulator circuit and the sinusoidal oscillator is evaluated using Pspice simulation and experimentation with VDDDA built from ICs AD830 and LM13700.

This article investigates a sliding mode control to generate stable operating methanol concentration for DMFC system by considering energy conversion efficiency according to different load demands. The model of DMFC system is established to describe the material flow as well as output performance. To achieve the maximum energy conversion efficiency under the required power demand, the reference methanol concentration is determined by analyzing the DMFC system output power as well as the reaction/crossover methanol flow rate. The sliding mode algorithm is adopted to track reference methanol concentration and the simulation results show that compared with fixed methanol concentration (e.g., concentration of 0.3 mo1/L and 0.4 mol/L), the proposed optimal methanol concentration can increase the energy conversion efficiency by 2.3% and 5.6%, as well as reduce the methanol consumption by 8.6% and 18.9% respectively.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126577226","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}

In order to deal with this important challenge, utilities put in place different demand-side management mechanism such as demand response programs and dynamic tariffication (DT) to shift electricity consumption outside peak period. To meet new needs and to respond to changes in the energy market, Hydro-Quebec undertakes an important research project, named SCÉNARIO, to simulate the impact of the different customers’ load profiles on the network. Dynamic pricing is one of the components of SCÉNARIO project which aimes to assess the impact of customer behavior on the distribution network during demand management. In this paper, we propose an algorithm for evaluating, modeling and predicting of the differential consumption profiles for residential customers subscribed to dynamic pricing tariffs. These kinds of investigations allow the power system planners to evaluate and predict the impact of the dynamic pricing programs on the power system behavior.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125738673","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}

A brand-new breakthrough configuration has come to the forefront in the advancing SOFC application. This novel form, known as symmetrical SOFC (S-SOFC), is a major topic in fuel cell development. By integrating lithiated nickel oxide-based materials that are typically used in lithium-ion battery applications and making them applicable for S-SOFC applications. The sol gel technique was used to synthesize the precursor lithiated nickel oxide with ruthenium as a dopant. This approach was deemed the most appropriate for handling lithiated materials in terms of effort, cost, and timeliness. As a result, the focus of these studies will be on initial work, especially the characterization and chemical performance of lithiated nickel doped ruthenium, abbreviated as $mathrm{LN}_{1-mathrm{x}} mathrm{R}_{mathrm{x}} mathrm{O}_{2}(mathrm{x}=0.4$ and 0.5) with various dopant compositions. The LNRO-based powder was analyzed in both oxidizing and reducing conditions to imitate the operating environment of a dual-functioning electrode. The symmetrical cell with the configuration $mathrm{LNRx} / mathrm{SDC} / mathrm{LNRx}$ was screen-printed and heat treated for 2 hours at $800{}^{circ} mathrm{C}$. As this electrode material has two functions, just one heat treatment step is necessary to assure the electrode is effectively attached to the electrolyte substrate (SDC). The samples were next examined for electrical conductivity of the electrode and, finally, EIS analysis. In a reduced environment (mixed gas of $mathrm{H}_{2}: mathrm{N}_{2}$), the activation energies for LNR4 and LNR5 are 0.13 and 0.14 eV respectively. Meanwhile, the ASR values derived from the EIS analysis of the best sample LNR4 measured in air and reduced environment at $800{}^{circ} mathrm{C}$ are $2.467 Omega mathrm{cm}^{2}$ and $0.030 Omega mathrm{cm}^{2}$, respectively. The morphological behavior of these components will be thoroughly examined. The findings indicated that the LNR4 dopant has a great potential as an electrode for the S-SOFC application, which is more than just a means to increase SOFC performance.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129565517","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}
