Published: November 2021

During the COVID-19 pandemic, social education moved from face to face to online learning to discourage large gatherings and crowds from catching the spread of the virus. This state of urgency involved all the students including university students. This paper aims to study the impacts of Pandemic Covid19 and identified the relationships between online learning, learning at home and self-management towards Malay Language learning among the students in public universities during MCO and 2) to develop a predictive model in the relationships between online learning, learning at home and self-management towards Malay Language learning among the students in public universities during MCO. Four variables which are online learning, learning at home, self-management, and Malay Language learning were analyzed using SPSS and AMOS. About 279 students from public universities were involved as respondents. Descriptive analysis, Correlation Pearson analysis and structural equation modeling (SEM) were used to answer the research objectives. An analysis of correlation Pearson showed that there are significant values derived from the relationship between online learning and Malay language learning (r=.578, p=.000). There is also a significant relationship between self-management and Malay language learning (r=.368, p=.000). However, there is no relationship between learning at home and Malay Language learning (r=.026, p=.294). The predictive model achieved good fit values of RMSEA=.061, IFI=.937, CFI=.936, TLI=.925 and Chisq/df=2.001. The implementation of online learning as a new norm and platform in teaching and learning Malay Language among the students gave a positive impact in terms of technology usage. However, there are needs for improvement to be considered in providing a more useful platform to change from face to face in conventional ways similarly to advanced technology. Meanwhile, the predictive model can serve as a source of reference in evaluating Malay language learning by using technology and other indicators for the future, for the sake of student’s achievement.

Dvorak technique operationally used all over the world for estimating the tropical cyclone intensity is based on satellite observations. It involves image pattern recognition based on certain empirical rules along with the analyst interpretation of organized convection. The computer-based algorithm can minimize these subjective judgement discrepancies between different analysis centers estimating the same storm. This modified version is called Advanced Objective Dvorak Technique (AODT) and which is applicable for well-developed tropical cyclones. In this paper the performance of the AODT is evaluated on three cases of the year 2004 tropical cyclones. Comparative analysis indicates the technique to be competitive with, the Dvorak-based intensity estimates produced operationally by satellite analysts from tropical analysis centers.

The paper presents the methodology and trial results of the district level value-added dynamical-synoptic forecast for rainfall. The technique was tried for forecasting districtwise rainfall during Pre-monsoon, Southwest Monsoon and Post monsoon seasons of 2005. The constituent dynamical models were T-80, MM5, ETA of the National Centre for Medium Range Weather Forecasting (NCMRWF) and the MM5 model operational at India Meteorological Department, New Delhi. The dynamical predictions were prepared using the rainfall predictions of the constituent models by assigning different weights. The dynamical predictions were converted into value-added synoptic-weather forecasts by taking into account other inputs like circulation features, vertical velocity, satellite information, synoptic charts and climatology etc. The experience during 2005 has shown that the value-added dynamical-synoptic system can produce 24, 48, 72 hours district level rainfall forecast of greater skill than the skills of the constituent models.

Radiation fog over north India has been studied using current weather data of thirteen airports. There has been a tremendous increase in the fog formation over northern parts of India in recent years. An attempt has been made to study the adverse impact of fog on aeronautical operations at Indira Gandhi International (I.G.I.) airport as total number of flights diverted during 1997-98, 1998-99, 1999-2000, 2000-01, 2001-02, 2002-03 and 2003-04 were about 900. I.G.I. airport is provided with a very efficient Instrument Landing System (ILS) for Cat-I, Cat-II and Cat-III operations. The utility of Runway Visual Ranges (RVRs) required for low visibility operations, calculated from skopographs, for the last fifteen years, has been discussed. Satellite observations on fog have been found to be in fair agreement with the surface observations. Most catastrophic fog formations, which occurred over north India during 1998-99, were found to be due to the enormous amount moisture flow from a severe cyclone formed in the Arabian Sea as evidenced in satellite imagery. An attempt has also been made to establish a relation of maximum temperature and Relative Humidity anomaly with the duration of fog at I.G.I. airport, Lucknow airport, Varanasi airport and Amritsar airport.

Authors: Nguyen Tuan Nhu 
Published: November 2021

Abstract— To secure communication from the sender to the receiver in wireless networks, cryptographic algorithms are usually used to encrypt data at the upper layers of a multi-tiered transmission model. Another emerging trend in the security of data transmitted over wireless networks is the physical layer security based on beamforming and interference fading communication technology and not using cryptographic algorithms. This trend has attracted increasing concerns from both academia and industry. This paper addresses how physical layer security can protect secret data compare with the traditional cryptographic encryption and which is the better cooperative relaying scheme with the state of the art approached methods in wireless relaying beamforming network.Tóm tắt— Việc bảo mật truyền thông vô tuyến từ nơi gửi đến nơi nhận thường sử dụng các thuật toán mật mã để mã hoá dữ liệu tại các tầng phía trên trong mô hình phân lớp.
