In signal processing, the accuracy of speech recognition remains a thought-provoking challenge. The filter designs assist speech recognition systems in terms of improving accuracy by parameter tuning. This task is some degree of form filter’s narrowed specifications which lead to complex nonlinear problems in speech recognition. This research aims to provide analysis on complex nonlinear environment and exploration with recent techniques in the combination of statistical-based design and Support Vector Machine (SVM) based learning techniques. Dynamic Bayes network is a dominant technique related to speech processing characterizing stack co-occurrences. This method is derived from mathematical and statistical formalism. It is also used to predict the word sequences along with the posterior probability method with the help of phonetic word unit recognition. This research involves the complexities of signal processing that it is possible to combine sentences with various types of noises at different signal-to-noise ratios (SNR) along with the measure of comparison between the two techniques.","PeriodicalId":20643,"journal":{"name":"Proposed for presentation at the 2020 Virtual MRS Fall Meeting & Exhibit held November 27 - December 4, 2020.","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77399020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The standardization, functional and operational necessities of this framework are defined by the Wireless Innovation Forum. If an unavoidable shipborne radar appears on the channel, the channel must be vacated by the lower tier users. The timing constraints on CBRS is also stringent. Wireless stations transmit short beacon frames termed as heartbeat signals. These signals consist of the wireless channel encryption data, Service Set Identifier (SSID) and other credential data. These signals also transmit commands to vacate a channel. The heartbeat interval, timing constraint and domain proxy features are analyzed in this paper. CBSD renunciation and spectrum acquisition is performed with the help of domain proxy based communication. The CBRS-SAS channel allocation algorithm is further investigated. The communication interoperability and network robustness can improved with the introduction of secondary SAS and secondary domain proxy respectively.","PeriodicalId":20643,"journal":{"name":"Proposed for presentation at the 2020 Virtual MRS Fall Meeting & Exhibit held November 27 - December 4, 2020.","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79791306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study aimed at the general objective to investigate how non-technological food service innovation models create value in restaurants. The specific objective was to establish and explore the relationship between non-technological food service innovation models and value creation. The study used a cross-sectional descriptive survey research design which involved those hotel restaurants in Nairobi County that were registered with the Tourism Regulatory Authority (TRA) as at 2016. Multistage stratified sampling—as well as purposeful and random sampling techniques—were used with a sample size of 385 respondents. Data collection instruments included questionnaires, interview guide, and observation-checklist, achieving a response rate of 82.9%. The coded data was analysed using descriptive and inferential statistical data analytical methods. Hypotheses were tested using multinomial regression, t-test and chi-square. Food service innovation model had no significant relationship with value creation in restaurants (p-value of 0.554). The study concludes that there is a need for a systematic procedure/model for developing non-technological food service innovations. To these end the study proposes a new food service innovation model with new variable such as consultation of professionals. This will enable an innovative organizational culture and lead to significant cost savings in the food service industry, among other benefits.","PeriodicalId":20643,"journal":{"name":"Proposed for presentation at the 2020 Virtual MRS Fall Meeting & Exhibit held November 27 - December 4, 2020.","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91540832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work engagement subscales, vigour, dedication and absorption were measured against the participants’ age, level of education and marital status. A cross-sectional survey was done from a sample (n = 100) of female participants. A biographical questionnaire and The Utrecht Work Engagement Scale (UWES) were administered. Significant relationships were found on the vigour, dedication and absorption subscales. FoH female employees younger than 35, those with tertiary education and those without life partners displayed higher levels of wellbeing. Therefore work engagement levels vary with regards to age, marital and educational status. Human resource specialists for hotels could measure work engagement and apply it through in-house policies and supportive practices as well as defend these practices regarding their FOH female employees as female employees are the majority of employees within the hospitality industry. The workforce in South Africa is characterized by demographic diversity. The variances of work engagement are imperative as it enhances the guest experience and improves productivity and ultimately increases financial turnover for the hotels who operate in a very competitive market.","PeriodicalId":20643,"journal":{"name":"Proposed for presentation at the 2020 Virtual MRS Fall Meeting & Exhibit held November 27 - December 4, 2020.","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88590720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to identify variables influencing tourism grading and to use them to construct a Bayesian Model for increasing the number of tourism establishments. Data was collected using an online survey questionnaire developed using the Survey Monkey tool. A total of 87 responses were received from 60 non-graded and 27 graded tourism establishments. The results indicate six factors affecting tourism grading, namely cost of grading, grading benefits, simplicity/complexity of grading application process, government funding, training of prospective grading applicants and computer literacy. The results further indicate grading cost and grading benefits as the most important factors for increasing the number of tourism establishments. The study implies that using this model will assist grading professionals to make informed decisions on initiatives aimed at increasing the number of graded tourism establishments. The study is among the first on implementation of AI to increase tourism grading establishments.","PeriodicalId":20643,"journal":{"name":"Proposed for presentation at the 2020 Virtual MRS Fall Meeting & Exhibit held November 27 - December 4, 2020.","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78482135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
