At the upper level, the model seeks to minimize both the total payment and peak load. The lower level, structured as a second-order conic (SOC) problem, aims to reduce overall generation costs subject to constraints of the second-order conic (SOC) branch flow model (BFM). The two levels interact through the optimal demand response and distribution locational marginal prices (DLMPs). The principles of convex duality principles together with the strong duality constraint are leveraged to transform the market-clearing problem into a single primal-dual problem. We also circumvent the non-linearity that stems from the DR payment term by incorporating discretizing loads and the big-<em>M</em> method, thus converting the problem into a mixed-integer SOC (MI-SOC) formulation. The merits of the proposed MI-SOC framework are validated through case studies conducted on the IEEE 33-bus test system, showcasing its potential to enforce price-elasticity demand response in distribution system's electricity markets.</p></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2090447924003046/pdfft?md5=4324b094b5853953899f240943b28b89&pid=1-s2.0-S2090447924003046-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141639129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evaluating their cost-effectiveness for construction, embodied energy (EE), and embodied carbon (EC) is the aim. The research method employed involves calculating the EE, EC, and cost of materials used during the production stage only. The results show that although RMC gives ease at a high carbon emission cost, RPC delivers great strength at a high cost and emissions. Utilizing waste resources, geopolymer concrete lowers emissions while providing sustainability. Reusing waste materials improves the performance of concrete and lowers pollution. The study emphasizes that, especially when waste is used well, strength need frequently translate into expense. RMC has a major negative influence on the environment while guarantees consistent quality. Despite its strength, RPC has issues with cost and material availability. The strength and emission reduction of geopolymer concrete are excellent. In geopolymers, alkali activators and steel fibers are the source of EE and EC, whereas cement and steel fibers are the reason for their high levels in RMC and RPC. Overall, the research indicates that favorable, ecologically friendly results are feasible obtained by improving the composition of concrete. To provide cost-effective and sustainable concrete compositions and enable well-informed decision-making in building projects, ongoing research and innovation are crucial.</p></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2090447924003010/pdfft?md5=3225a14c3eb1d7b38a222ffcb3b01e47&pid=1-s2.0-S2090447924003010-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141729370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The challenges to migrating from four-terminal (4-T) to two-terminal (2-T) designs are highlighted and possible solutions are proposed. To commence, a calibration procedure for the two subcells is conducted in alignment with experimental investigations. The benchmarked solar cells yield a power conversion efficiency (PCE) of 8.08 % for the upper subcell and 10.58 % for the lower subcell. Subsequently, upon integration of both subcells within the initial 4-T Sb₂S₃/Sb₂Se₃ TFTSC, the resultant PV cell attains a PCE of 12.27 %. Before transitioning it to a more efficient 2T tandem configuration, we explore alternative inorganic HTL materials to the Spiro-OMeTAD HTL to overcome its practical considerations. Cu₂O is found to be the best HTL alternative to be included for both subcells. Upon stacking into the tandem structure, the combined cell exhibited an efficiency of 15.68 % and a notable <em>J_sc</em> of 16.23 mA/cm². To further enhance the tandem performance, the device structure is optimized by engineering the CBO of two sub-cells and employing a double ETL design for the front sub-cell.

This research contributes to the domain of LiDAR-based lane detection across three pivotal areas. Firstly, we introduce the BoostedDim Attention method, enhancing traditional Multi-Head Self-Attention (MHA) calculations within the shallow Vision Transformers-based K-Lane baseline model. This method excels, particularly in demanding scenarios, including unknown and nighttime conditions at short ranges (0–30 m) and daytime scenarios for long ranges (30–50 m).

These metrics consider sensor-specific and task-specific factors, offering a comprehensive assessment of LiDAR-based lane detection capabilities. Lastly, our investigation sheds light on the significance of calibrated reflectivity and intensity data, revealing their impact on lane detection under various lighting conditions.
