FM receiver systems which generally consist of analog components began to shift to more sophisticated devices. Software Defined Radio (SDR) is a software configurable radio receiving device. This paper describes the implementation of a complex differentiation FM receiver based on an SDR device. HackRF is an SDR device with a frequency band that can be used as a signal receiver from FM broadcast transmitters. The FM signal will be received by HackRF which serves to downconvert the signal. The FM signal is mixed with a complex exponential signal at a local frequency to be demodulated. The result of mixing these signals produces in-phase and quadrature signals. The signals are processed separately or can be called complex differentiation discriminators. These complex differentiation distinctions are described at each stage of the mathematical analysis. The results obtained from this differentiation complex FM receiver indicate that HackRF can be used as a complex differentiation FM receiver.","PeriodicalId":315172,"journal":{"name":"2021 International Research Symposium On Advanced Engineering And Vocational Education (IRSAEVE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131697518","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}

Cybergogy is a modernization educational technique based on the empowerment of Information and Communication Technology (ICT) that is unconstrained by place, time, culture, or country. The global Covid-19 pandemic had large-scale institutional and behavioral ‘shock effects' in a variety of human activities, including schooling. The quick shift from traditional classroom to online teaching and learning has driven the application of Cybergogy out of the present educational process. The purpose of this research is to identify the level of Cybergogy readiness in terms of cognitive, social and emotive factors and the significant differences between the demographic factor among technical students. The design of this study was descriptive with a quantitative approach. A total of 54 technical students from Faculty of Technical and Vocational Education (FPTV) at University Tun Hussein Onn Malaysia (UTHM) were random cluster selected as samples. A set of modified questionnaires from past studies were used as research instruments. The finding indicates that technical students slightly to moderately ready for online learning. Female students have a higher level of preparation for online learning than male students. According to this study, junior students in year one are more prepared for online classes than senior students since they are more interested in learning online. Students in the BBC program are more equipped for online learning than those in the BBB and BBG programs. When compared to a student who learns in a traditional approach, academic achievement is not as poor because the majority of students have good CGP As. Furthermore, students who study at home have a modest level of Cybergogy readiness.","PeriodicalId":315172,"journal":{"name":"2021 International Research Symposium On Advanced Engineering And Vocational Education (IRSAEVE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126893742","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}

When poling in a high humidity condition where the atmosphere is not controlled, the piezoelectric constant d33 was confirmed to be as small as a number [pC/N]. On the other hand, when the poling was performed while the humidity was controlled by injecting nitrogen gas or dry air, a relatively large value of several tens [pC/N] was confirmed. Also, the ultrasonic response of these samples was measured.

The major purpose is to create a Smart Augmented Reality (SAR) device that will make it easier for farmers to utilize cup sealers. As the lockout mechanism is known all over the world, food distribution has a vulnerability, Growers, in particular fruit farmers, benefit from the invention of this technique because fruit cannot be preserved for lengthy periods of time. Farmers can now simply pack Citrus Fruit into Cups that may last up to two months. The Cup Sealer SAR is a completely automatic cup sealer machine with a SAR mechanism that also includes a Bluetooth remote and AR-based instructions. Smart AR used in this study is the development of AR without markers, or AR without marker objects, the smart AR concept used is to detect objects that match the Cup Sealer then provide interaction with the object through the appearance of tutorials on using objects, design cup selaer and notifications if cup sealer machine is ready to use. The SAR Sealer Cup has also met the eligibility criteria for producing this product at an advanced stage, as evidenced by the degree of readability and product efficiency of 83.45 percent of 140 respondents, indicating that this product is very suited for usage. The results of the expert test were 87.25 percent, this is categorized as good when the test is tested by experts, you will find that the average results acquired from all testing carried out are 81 percent in terms of design and also the appearance that makes it easy for the user.
