With the out-performance of neural network technology, the task of sentiment analysis can be addressed by advanced deep learning models. In this work, a combination model of Bidirectional-CARU (Bi-CARU) and Recurrent CNN is introduced to the sentiment analysis tasks. The proposed Bi-CAUR consists of three layers designed to obtain the main features of the input sequence, which can alleviate the long-term dependency problem and perform kernel information filtering from concrete to abstract, effectively improving the performance of the intermediate network on this problem. Next, the recursive structure of the CNN is connected to Bi-CARU to determine the sentiment analysis. The proposed Recurrent CNN implementation accepts features produced by its own previous convolution and pooling, which incorporates the performance of a CNN and requires only fewer parameters. Experimental results show that we are slightly more accurate, achieve faster convergence, and require fewer training parameters.","PeriodicalId":361369,"journal":{"name":"2023 8th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115211659","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}

Double-glazed units filled with various organic PCMs (OM 21, OM 30, and OM 35) were tested for their solar and thermal properties, In two quite distinct climates in India (temperate and hot), the potential for energy savings and carbon emission abatement using PCM-filled double-glazing units for a multi-story office building was explored. Computations of the year-round cost savings of glazing systems for different latent heat utilization levels (25, 50, 75, and 100%) revealed that the full utilization of latent heat (100%) resulted in the maximum cost reductions of 69817 and 66344 dollars per year for temperate (New Delhi) and hot (Madras) climates. The glazing systems with OM 30 PCMs have concluded the highest carbon emission abatements of 855 and 812 tCO2/year for temperate and hot climates, respectively. Additionally, the economic analysis was performed, and it was discovered that OM30 had the shortest payback period of 3.2 years for 100% latent heat utilization under hot environmental conditions. PCM-based glazing systems revealed remarkable outcomes and can help achieve better thermal conditions and energy conservation in buildings.","PeriodicalId":361369,"journal":{"name":"2023 8th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124400225","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 addition, their usefulness has been further amplified by the combination of the IoT services with various technologies and innovations. For instance, the Distributed Ledger Technologies (DLTs) and the blockchains are supporting the IoT domain with their useful services and properties, e.g., trust and automation, since some years. However, the increasing interest in such a combination and the race towards the most significant innovation in the sector is shifting the focus away from some of the most important issues and questions. One of them regards the usefulness of the adopted technologies and their effectiveness with respect to similar alternative solutions. For example, the most frequently used approach to save data in a DLT foresees the simultaneous use of an off-chain database to store the actual data, and a DLT platform itself to guarantee some properties, e.g. to verify the immutability of such data. Such a common practice is adopted by almost every work on the domain but the real benefits brought by this approach are not usually measured. For this reason, the present paper is focused on an evaluation of two approaches: one based on the combination of DLT and off-chain databases, and the other one based only on the usage of the DLT. A realistic logistics use case has been introduced to compare the performances of each approach.","PeriodicalId":361369,"journal":{"name":"2023 8th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121074300","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}

Due to eccentric compressive load, the beam is subjected to compression, bending in two principal planes and torsion simultaneously. Theory of bending and theory of torsion of open cross sections with influence of shear are utilized in the static analysis of the beam-column to obtain analytical expressions for the normal stress. Also, translational and rotational displacements are defined using classical Vlasov solution and deflections and angle of torsion are augmented with additional components due to shear in bending and torsion. The analytical solutions according to Vlasov and those obtained with theory of bending and torsion with influence of shear are compared to the finite element method solutions obtained by using shell finite elements. The relative errors, calculated with classical Vlasov approach with respect to the finite element solutions, in amount of 30-75% for normal stress and 17-40% for the maximum displacement are reduced to less than 5% using the proposed method. It is proved that the shear effect must be taken into analysis of short thin-walled beams for this type of the problems.","PeriodicalId":361369,"journal":{"name":"2023 8th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122751430","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}

With the development of data science, many methods have been proposed to handle a large amount of operational data and to understand the impact of various factors on pipeline safety. Weld failure is related to many factors, and identifying their correlation helps to grasp weld information better, develop maintenance strategies in advance, and improve weld management. In this study, two methods for understanding correlations of failure factors of girth welds were studied, the Pearson correlation coefficient method and the random forest importance coefficient method. Factors such as repair history, whether connector, whether crossing, and pipe joint length, are considered. The magnitude of the impact of each factor on pipeline safety can be judged to ensure that the hard requirements of each factor are met during the pipeline development process, while reducing the probability of risk to the pipeline. A case of a gas trunk line in China was studied to test the method. The relevance of key elements such as short pipe, repair history, pipe joint length, and geological hazards to the detection of non-destructive defects in pipelines were analyzed. The results show that correlation analysis of pipeline-related factors can provide guidance for pipeline safety and help reduce pipeline risks.","PeriodicalId":361369,"journal":{"name":"2023 8th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114457148","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}

However, individuals with eating disorders often face challenges in accessing psychological support, making smartphone apps a potentially valuable avenue for intervention. Despite their popularity, there is a scarcity of studies investigating the safety and efficacy of these apps. This narrative review aims to examine the usage and efficacy of smartphone applications for eating disorders. A comprehensive search was conducted using the PubMed database to identify relevant publications. The marketplace is currently small, with a few popular apps accounting for almost all active users. Clinicians should familiarize themselves with these apps to recommend them to their patients. However, the current marketplace should prioritize the development of evidence-based apps, as there is a lack of research on their efficacy. Clinicians should consider this when integrating apps into their practice. Although some studies have shown promising results with online self-help interventions in reducing behavioral symptoms of eating disorders, it is important to note that many studies have methodological limitations, such as poor user adherence and high dropout rates. Overall, the scarcity of available, evidence-based apps for eating disorders highlights the need for further research in this area to maximize its potential to help patients achieve long term remission.","PeriodicalId":361369,"journal":{"name":"2023 8th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122172922","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}

Ensuring these conditions comes at significant energy requirements, which made hospitals primary targets for improving their efficiency over the last decades in order to make them more sustainable and also financially viable. However, resilience is a vital quality for hospital buildings which has to be guaranteed and which sets demand both on the building itself and on the infrastructure of energy grids. There are a series of threats to a hospital’s resilience, against which precautionary measures have to be taken, considering the likelihood of the threats and their possible impact on the hospital’s operation. Achieving resilience and sustainability may seem a contradiction at a first glance, but in fact there are more common aspects than competing requirements as it will be discussed in this paper.","PeriodicalId":361369,"journal":{"name":"2023 8th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128780545","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}
