Different suspension systems were tested at a maximum speed of 240 km/hr, with the Intelligent Control Suspension System (ICSS) and the Passive Suspension System (PSS) standing out. RMS acceleration and displacement data, as well as ride quality and comfort parameters, were used to make the comparisons. Acceleration attenuation studies reveal that the ICSS is superior than the PSS, with reductions ranging from 7.64 to 11.66% across different ICSS configurations. Displacement values improve significantly using ICSS, obtaining reductions ranging from 25.89 to 55.80%. With the application of ICSS, ride quality and comfort indices improve by 8.19 to 31.50%. These findings show that the ICSS is very successful in reducing discomfort caused by rail vibrations and improving passenger comfort. This research emphasizes the significance of acceleration and displacement responses in suspension design and advocates for the use of ICSS for more efficient and pleasant train travel. The adaptable nature of ICSS allows for real-time optimization of suspension settings, which contributes to the development of a sustainable and enjoyable railway sector.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"47 4","pages":"391 - 394"},"PeriodicalIF":1.2,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138531771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arithmetic operations such as addition and multiplication play a major role in DSP applications. As a result, there is thorough research on various methods to achieve high-speed and low-power DSP applications. In multipliers, the Vedic multiplier is considered as a fast multiplier because of its consistent structure resulting in low power consumption. Array multiplier is implemented with half and full adders. This kind of implementation of the array multiplier needs the previous output to provide the last word output, which leads to an increase in delay. In DSP applications, the key problem corresponds to carry generation delay. To overcome the delay, a carry-lookahead adder is used. In this work, a Vedic multiplier using a carry-lookahead adder is used with quaternary logic in the CMOS process. The width and length of the transistors are defined as 1.7 µm (PMOS), 850 nm (NMOS), and 180 nm for 1.8 V supply in 180 nm CMOS process. Simulation results show that the designed Vedic multiplier enhances the performance when compared with the conventional multiplier.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"47 4","pages":"379 - 384"},"PeriodicalIF":1.2,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40009-023-01363-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138531775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It hampers word recognition, spelling, comprehension and decoding skills. The objective of this study was to ascertain the occurrence of dyslexia and its influence on mathematics achievement among secondary school students in Nepal. A mixed-method research design was employed for this purpose. The sample included 904 students from grade IX selected randomly. To identify dyslexic students, quantitative data was collected using adapted assessment tools such as the dyslexic student’s checklist for teachers (DSCT), dyslexic students’ checklist for parents (DSCP) and dyslexia identification self-assessment questionnaire (DISQ). These tools were utilized to screen for dyslexia. Qualitative data was gathered through an observation checklist and semi-structured interviews with selected students to verify the presence of dyslexia. The findings of the study revealed a prevalence rate of 5.53% for dyslexic students at the secondary level, with a slightly higher prevalence among male students (5.94%) compared to female students (5.22%). Moreover, the research demonstrated that dyslexic students exhibited significantly lower achievement scores in mathematics when compared to their non-dyslexic peers.","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"56 5","pages":"0"},"PeriodicalIF":1.1,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135341634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
