Cyclostationary Algorithm for Signal Analysis in Cognitive 4G Networks with Spectral Sensing and Resource Allocation

Cognitive Radio (CR) effectively involved in the management of spectrum to perform improved data transmission. CR system actively engaged in the data sensing, learning and dynamic adjustment of radio spectrum parameters with management of unused spectrum in the signal. The spectrum sensing is indispensable in the CR for the management of Primary Users (PUs) and Secondary users (SUs) without any interference. Spectrum sensing is considered as the effective adaptive signal processing model to evaluate the computational complexity model for the signal transmission through Matched filtering, Waveform and Cyclostationary based Energy sensing model. Cyclostationary based model is effective for the energy based sensing model based on unique characteristics with estimation of available channel in the spectrum to extract the received signal in the PU signal. Cyclostationary based model uses the spectrum availability without any periodic property to extract the noise features. This paper developed a Adaptive Cross Score Cyclostationary (ACSCS) to evaluate the spectrum sensing in the CR network. The developed ACSCS model uses the computational complexity with estimation of Signal-to-Interference-and-Noise Ratio (SINR) elimination of cost function. ACSCS model uses the Adaptive Least square Spectral Self-Coherence Restoral (SCORE) with the Adaptive Cross Score (ACS) to overcome the issues in CR. With the derived ACSCS algorithm minimizes the computational complexity based on cost function compared with the ACS algorithm. To minimize the computational complexity pipeline triangular array based Gram-Schmidt Orthogonalization (GSO) structure for the optimization of network. The simulation performance analysis with the ACSCS scheme uses the Rician Multipath Fading channel to estimate detection probability to sense the Receiver Operating Characteristics, detection probability and probability of false alarm using Maximum Likelihood (ML) detector. The ACSC model uses the Square-law combining (SLC) with the moment generation function in the multipath fading channel for the channel sensing with reduced computational complexity. The simulation analysis expressed that ACSC scheme achieves the maximal detection probability value of 1. The analysis expressed that proposed ACSC scheme achieves the improved channel estimation in the 4G communication environment

Comparative studies on the perception of risk to disasters in teacher’s college

The Sendai Framework states that all sectors,including the education sector, must be committedto the achievement of its goals, with apriority on understanding disaster risk (UNISDR, 2015).Understanding of disaster risk from universities begins inthe classroom and throughout the university, especiallyin the curriculum, making it necessary to incorporate riskmanagement into undergraduate and graduate careers.Therefore, it was considered of great importance to knowthe perception of disaster risk by university professors,since the figure of the professor is a key factor in the processof understanding the subject. The study was basedon a comparative study between universities and facultiesof the Universidad de las Américas in Panama (UDELAS)and the pedagogical faculties of the Universidad Central“Marta Abreu” de las Villas, (UCLV) Cuba, based on anon-experimental - transactional - descriptive design. Theinstrument developed for data collection was a questionnaire.The results of this study allowed us to comparethe degree of knowledge about disaster risk, the way inwhich risk is identified in institutions, the relationship withthe environment and the behavior towards these eventsof the population participating in this study

“From bricks to Click": Metacognitive Reading Skills of Students in the Pre and During Pandemic Era

This paper addressed the emerging gap on the quality of reading instruction before and during the COVID 19 Pandemic onslaught. This study generally aimed to determine how EFL university students utilized metacognitive online reading methods before and after the Covid-19 outbreak. A study was conducted to investigate whether EFL university students' use of metacognitive reading methods had changed before and after the Covid-19 pandemic, and if so, what had changed. This study employed mixed-methods research utilizing quantitively and qualitative research designs.  Testing the significant difference on the reading strategies of the students using t-test, the result revealed there is a significant difference on the reading strategies of the students. This indicates that during COVID 19 the students were able to attain a very high level of reading strategies compared during the pre-pandemic era which is attributed to the adoption of online learning where the mode of instruction is taken virtually and reading references among the students were mostly taken thru online access. On the qualitative context utilizing exploratory sequential design, revealed that EFL students were able to better their metacognitive online reading strategies during the COVID 19 as reflected in four themes: easier access of reading materials, flexibility of time and space, characteristics of e-books, and issues on the disruption of reading concentration brought by online reading activities. As a result, there is a perceived need to improve EFL students' metacognitive understanding of online reading techniques and help them become better online English readers. Helping students develop their metacognitive awareness of online reading methods and helping them master their metacognitive reading strategy usage are two approaches to help EFL students better comprehend online texts
