The objective of the research is to better understand how digital learning, specifically how it affects employability, skills, and economic growth, may enhance the development of human capital within the framework of Pakistan's educational system. This research critically examines the economics of education in Pakistan by addressing significant research issues. It examines the financial barriers to education, focusing on issues including financial inequality and procedural hurdles. The research examines how initiatives for curriculum reform and teacher training help educational institutions support human capital development. It also examines the effects of online education, demonstrating its ability to close knowledge gaps and improve digital literacy. Despite obstacles like the digital divide, this research emphasizes the significance of strategic measures to guarantee equal access to high-quality education and build a trained, flexible workforce essential for Pakistan's socio-economic success. However, implement evidence-based policies to enhance the management of education. Research in the future should concentrate on inventive financing approaches and reliable data.

“…Although these data are considered unstructured, through techniques such as sentiment analysis and the extraction of relevant words such as the IF-IDF method, it is possible to extract significant qualitative and quantitative information on student satisfaction with respect to the different services offered in the field of teaching, research and social projection; represent a strategy to be used in parallel and crossed results contributing to its validation and suppressing possible biases. Analyzing the opinions generated through social networks allows the visualization of dominant comments avoiding falling into any type of bias, the analysis of sentiments guarantees the ability to extract subjective information on sensitive aspects [34]. The results of processing opinions collected from social networks form a component that contributes to success because it represents a competitive advantage for the institution that applies it as a knowledge-generating element [35].…”

<span lang="EN-US">With the incursion of data science into the academic field and the massification of social networks, it is possible to extract information on student satisfaction that contributes to feedback on teacher teaching strategies and methods. This article aims to determine student satisfaction with teaching performance, through sentiment analysis. Methodologically, the research is of a non-experimental longitudinal design, with a quantitative approach. Data collection was carried out through the social network Twitter, and data analysis was carried out through the sentiment analysis technique. As a result, it was identified that in the first week of class, the highest level of satisfaction was obtained, reaching 96.3% of the total number of students. Meanwhile, in the evaluation weeks, the highest level of dissatisfaction was reaching 29.17%. It is concluded that when going from totally virtual learning to hybrid learning, students express a certain level of dissatisfaction typical of a process of progressive adaptation. Therefore, teachers should take advantage of these findings to redesign assessment rubrics in the context of hybrid teaching. Aspects such as collecting opinions through social networks and extracting a degree of satisfaction through them apply in a crossed way to other professional fields.</span>

“…With the development of communication networks, the network architecture is becoming increasingly complex. The phase and carrier frequency estimation of received signals is made possible by capturing weak signals, which is the first step in electronic communication networks [1][2][3]. In recent years, scientists have conducted much research on the subject of weak signal capture and have developed typical methods such as time-domain-based serial capture method, frequency-domain based parallel phase search capture method, etc.…”

In this paper, the weighted class fractional Fourier transform is redefined by means of the weighted superposition of state functions, and the Fourier transform is applied to dissect the intrinsic relationship between the M-WFRFT and the 4-WFRFT and to obtain the weighting coefficients of the electronic communication signals. On the basis of the WFRFT discrete algorithm, the electronic communication signal is expanded to include M a term after the M -WFRFT and the hybrid carrier modulation method based on the WFRFT is given. According to the design idea of the electronic communication system, the hardware part and software part of the electronic communication system are designed, and the electronic communication signal modulation recognition system is experimentally analyzed by using the simulation experiment method. The results show that when the signal-to-noise ratio is -8dB and the optimization algorithms are the Sgd algorithm, Sgdm algorithm, and Adam algorithm, the modulation identification accuracy of OFDM signal is 39.3%, 57.5% and 43.5%, respectively, which indicates that the Sgdm optimization algorithm is the most suitable one compared with other algorithms, and it is more effective in the modulation identification of OFDM signals at low signal-to-noise ratio. The number of scans of the three-layer multi-parameter WFRFT signal by the non-cooperative party is 6.4 × 1013 times, and the increase in the number of scans leads to an increase in the cost paid by the non-cooperative party, which confirms that the secure communication system based on three-layer weighted fractional-order Fourier transform has good resistance to parameter scanning characteristics and high confidentiality. This study further improves the a priori parameter setting of the electronic communication system and enhances its complexity, resulting in better anti-interception identification features.
