F-OFDM in a novel form for analyzing 5G networks
The need for internet of things (IoT) and machine-to-machine communication (MTC) has been growing rapidly all across the world. To meet the client's needs, many literature reviews were undertaken in several countries. Orthogonal frequency division multiplexing (OFDM), Universal Filtered Multi-Carrier (UFMC), filter-bank multicarrier offset construction amplitude modulation (FBMC-OQAM), generalized frequency division multiplexing (GFDM), and others are candidates for LTE, LTE advance, and 5G, according to the majority of the researchers. However, because it is sensitive to propagation and noise, such as amplitude, with a huge dynamic range, it requires RF power amplifiers with a high peak to average power quantitative relationship; consequently, it is not recommended for LTE, LTE advance, or 5G. As a result, the same concerns were addressed by introducing innovative type filtered orthogonal frequency division multiplexing (F- OFDM), which was the subject of this study. In addition, F-OFDM mathematical models were constructed and simulated in the MATLAB software environment. To validate the proposed innovative F-OFDM, OFDM was compared. For innovative F-OFDM, the simulated result was 0.00083333 bit error rate (BER). Furthermore, the bit error rate (BER) of F-OFDM over OFDM was 89.4 percent, and the peak to average power ratio was 17 percent. The simulation results unmistakably show that the suggested innovative F-OFDM is the greatest fit for LTE, LTE advanced, and 5G contenders
Mathematical Modeling: A Study of Corruption among Students of Nigeria Tertiary Institutions
Corruption is a slow poison damaging students and consequently societies and nations, virtually, all students of Nigerian tertiary institutions are exposed to corruption. In this study, an attempt is made to formulate the dynamics of corruption among students of Nigerian tertiary institutions. We describe mathematical modeling of corruption among students using an epidemiological compartment model. The population at risk of adopting corrupt ideology was divided into four compartments: S(t) is the susceptible class, E(t) is the Exposed class, C(t) is the Corrupted class and P(t) is the punished class. The positivity and boundedness of the model were established. The model possesses both corruption-free and endemic equilibrium. Likewise, the model exhibits threshold dynamics characterized by the basic reproduction number R0. The numerical implementation of the model reveals that corruption will persist among Nigeria students if the root cause were not eradicated
Proposed Taxonomy of Strategies for Translating English Proverbs into Arabic
The present study aimed to provide a proposed taxonomy of strategies for translating English proverbs into Arabic. The proposed taxonomy classified the strategies for the Arabic translation of English proverbs into five, depending on the form and meaning of proverbs and the availability of equivalent proverbs in Arabic. The strategies are an exact match between English and Arabic proverbs, a match except for key culture-specific and environment-specific words, a complete mismatch in form with intact meaning, equivalent lines of Arabic poetry to some English proverbs and literal translation with or without an explanation. The taxonomy was applied to a sample of English proverbs with their Arabic equivalents per the classification of translation strategies suggested in this study
Negation in American Discourse: A Socio-Cognitive Study
The present study cognitive aims to investigate the negation phenomenon in American political discourse under Critical Discourse Analysis (CDA) principles. The research sample includes two speeches given by Clinton and Trump in their election campaigns in 2016. Since the nature of the study follows the social-cognitive approach, the researcher adopted two models of analysis to achieve the study’s objectives: First, the theoretical framework of MST (developed by Fauconnier (1994), Fauconnier and Sweetser (1996) to examine meaning construction resulting from building different levels of negative mental spaces by two different genders the selected speeches. Second, pragmatic model to examine the role of gender from the functional perspective of negation, five pragmatic strategies here are adopted, namely, Speech Act, off-record, on-record, presupposition (based on the politeness model of Brown and Levinson, 1987), and violation of Grice’s maxims (1975). The study follows a qualitative method in the analytical interpretation of data to understand the negative impact of a contextual model and subjective model (personal ideology and knowledge) and quantitative analysis to find out the frequencies and the types of negatives. The findings show that both genders are biased to use negatives in their election campaigns to damage f each other’s face, and both similarly succeed in using pragmatic strategies within the scope of negative spaces, with some differences to mention
A contrastive perspective on Moroccan learners’ (in) directness in their interlanguage requests: Cross-cultural and pedagogical implications
This study investigated interlanguage request performance by Moroccan learners of English (MLs) from a contrastive perspective. More specifically, it explored how MLs’ interlanguage requests converged or diverged from English Natives’ (ENs) requests in the use of strategy types and (in) directness. First, a contrastive pragmatic analysis of requests by Moroccan natives (MNs) and ENs is deemed necessary to provide native baseline data and establish MNs’ and ENs’ pragmatic norms of request performance. Second, an interlanguage request analysis is conducted to reveal the pragmatic features of MLs’ requests. The three sets of data for this study were collected via an open questionnaire as it serves the purpose of this investigation. The results revealed that MLs deviated from the ENs’ pragmatic norms of (in) directness, mostly by falling back on their native pragmatic norms, which bears testimony to pragmatic transfer. Requests do not seem to be conceived of in the same way by MNs and ENs, and MLs transferred their native request conception when performing in English. MLs used more direct strategies. The study predicts instances of cross-cultural misunderstanding and pragmatic failure in intercultural encounters between MLs and ENs, which is likely to cause undesirable cross-cultural clichés and stereotypes. The paper suggests some pedagogical implications to alleviate this problem among MLs.
The Pragmatics of Phatic Utterances and Pleasantries in Nigerian Students Unionism: Phatic Utterances in Nigerian Students Unionism
The apex body of students in any tertiary institution in Nigeria is student union which is led by students and for the students. Over the years, a unique pattern of greeting has evolved in Students Unionism. Student leaders tend to exhibit various phatic communions to develop and maintain social relationship. Extant studies on student union in the Nigerian context have largely addressed the phenomenon from the sociological and political perspectives with little attention paid to it from a linguistic perspective. This study, therefore, investigates the pragmatic functions of phatic utterances and pleasantries among student leaders in selected Nigerian tertiary institutions. Data was gathered from six tertiary institutions in the south-western part of Nigeria through observation and interview methods. Using Mey’s Pragmatic Act theory as the analytical tool, it was revealed that seven major functions are achieved with the phatic communion in Students Unionism. These include disclosure of political position, prayer invocation, placement by hierarchical status, assertion of loyalty and support, incitation of special recognition, issuance of warning and unveiling personality traits of student leaders. These are achieved through the deployment of pragmatic tools such as used are speech acts, physical acts and prosody in the activity part and in the textual part, reference (REF), inference (INF), metaphor (MPH) and Shared Social/Situation Knowledge (SSK) are deployed. These phatic communions are intentionally and uniquely used in the domain of Students Unionism to communicate a lot of messages in the achievement of their desired goa
Contributions of Business Intelligence (BI) on Decisions Programming for Telecommunications Companies in Yemen
This study aimed at studying the contributions of the BI on decision programming. The study was performed in three telecommunication companies in Yemen, namely Sabafon, MTN and Yemen Mobile. Companies’ managers as well as IT specialists were selected to expose their views and describe the awareness of the BI and its impact on decision programming. Questionnaire and observation were the best techniques for this study to collect the accurate data. Furthermore, data was statistically analyzed using descriptive statistics tools, MANOVA and Univariate ANOVA test. The empirical findings reveal the role and positive impact of BI on decisions programming at the same time companies do not implement the new technologies that are appropriate for enhancing the BI. Hence it was recommended that companies should start applying machine learning and develop digital dashboards to illustrate all required data and information which cover all companies’ area
Self-Efficacy and Achievement of Students in the Government Schools of Rawalakot Azad Kashmir
Self-viability is a vigorously explored theme inside the instructive discipline and is an essential mark of extensive-term execution and adequacy. Our public preparing gadget needs great fledgling educators possessing awesome feelings of viability and genuine instructing limit. The exhibited understudy educator execution appraisal is being utilized the nation over as a method for evaluating the preparation of student instructors for a hit calling in tutoring. Since self-adequacy is most intensely associated with early audits, it's crucial to comprehend the researcher's self-viability. This ganders found that the connection between self-viability and achievement rating toward the finish of the test, understudies inside the public authority resources of Rawalakot is standard. Self-adequacy in sure understudies changed into saw to diminish later inward accommodation while given remarks on advancement and execution. All people had been demonstrated to increment in self-adequacy from the beginning of the student as far as possible accurate to form fundamentally dependent on the writing evaluation. Understudy mentor execution is contrarily related to the other in self-viability from the start to the stop of understudy training. These outcomes show that the more the exchange self-viability from the start of the instructing as far as possible, the reduction a researcher performs at the achievement. This likewise proposes that when the other in self-adequacy is less, satisfaction execution is extra
Students’ Social Media Access, Sources, and Reasons for Utilization: Basis for Integration in the Curriculum
This study investigated access through devices, internet sources, and reasons for using social media among purposively selected students in a tertiary education institution in Cebu, Philippines. This mixed qualitative-quantitative study used a survey and interview to gather data. The study found that the top three access devices were android phones, desktop computers in internet cafés, and personal laptops. In contrast, the top three internet sources were smartphone data plans, Wi-Fi connections in internet cafes, restaurants, coffee shops, etc., and Wi-Fi connections in school. The top reason for using social media was to get news and information and to learn about significant events, people, and places. It was concluded that the students were highly engaged in social media using their devices. Internet access allowed them to perform tasks in their accounts for several reasons. The findings can serve as the basis for technology and social media integration in the curriculum.
Self-esteem and its Relationship to English Oral Performance among Yemeni EFL Undergraduate Learners
The present study aims to explore the level of self-esteem among the Yemeni EFL university students and find out whether female and male significantly vary in their self-esteem. It also examines the level of the Yemeni Arabic speaking EFL university students in English oral performance and its relationship with their self-esteem. For the data collection, three instruments have been used. First, 50 Yemeni EFL undergraduate students (female=38; male=12) completed the self-esteem scale (SES) developed by the researcher along with the standardized Self-esteem Scale by Rosenberg(1965). Then, an oral test was set to test students' performance in English speaking skill. The third tool is a spoken test checklist prepared to score the students’ oral performance. The data collected were statistically processed by using SPSS. The results obtained show that: (a) Yemeni EFL undergraduate learners show high self-esteem degree (M=2.90 (out of 5), percentage73%) in both dimensions (c) No significant differences have been found between females’ and males’ self-esteem, (d) There is a very slight difference between female and male towards their own perception towards themselves, but it is not significant, (e) The level of Yemeni EFL undergraduate learners in speaking skill is a bit low (M= 9.94 (out of 20); SD=2.4; percentage 49.4%), (f) There is a significant relationship between self-esteem and spoken performance by Yemeni EFL learners (r=.365, p-value=.009<0.01). As a whole, this study contributed to the ESL/EFL by providing information on Yemeni Arabic speaking undergraduate female and male EFL learners in terms of their self-esteem and their oral communication performance
