In recent years, insects have emerged as a promising substitute for traditional feedstocks in biogas production due to their high protein and lipid content, rapid growth rate, and low environmental impact. This literature review aims to provide an overview of the advances in insect employment for sustainable energy generation. It presents a comprehensive analysis of the existing literature, highlighting the potential of insects as viable and renewable biogas sources, the challenges associated with insect rearing and processing, and the technological innovations in optimizing their utilization. The review also discusses the economic viability and environmental benefits of employing in-sects in biogas production and future research directions in this emerging field. The nutrient content of fermentable or biodegradable organic materials will serve as an ingredient in the production of biogas/biomethane. Nutrient-rich insect frass will eliminate the need for co-digestion with another feedstock, as previously examined. Currently, insect waste is not a familiar feedstock for biogas production, as its first utilization dates back to 2018, when 177-225 mL/g TS of biomethane was realized.","PeriodicalId":388003,"journal":{"name":"Journal of Studies in Science and Engineering","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128046434","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}

There are many ways to find the modulation type, but only a few good ways to deal with signals with a lot of noise. This study comes up with a way to test how well different machine learning algorithms can handle noise when detecting digital and analogue modulations. This study looks at the four most common digital and analogue modulations: Phase Shift Keying, Quadrature Phase Shift Keying, Amplitude Modulation, and Morse Code. A signal noise rate from -10dB to +25dB is used to find these modulations. We used machine learning algorithms to determine the modulation type like Decision Tree, Random Forest, Support Vectors Machine, and k-nearest neighbours. After the IQ samples had been converted to the amplitude of samples and radio frequency format, the accuracy of each method looked good. Still, in the format of the sample phase, each algorithm's accuracy was less. The results show that the proposed method works to find the signals that have noises. When there is less noise, the random forest algorithm gives better results than SVM, but SVM gives better results when there is more noise.","PeriodicalId":388003,"journal":{"name":"Journal of Studies in Science and Engineering","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131536287","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 results of measuring the effects of using a ventilator between the concrete slabs and gypsum boards indicated that the moving air in the layer between slabs by using the ventilation process has more effect in cooling roofs and the room temperature had less than that of slabs that do not use ventilation, and so using baffle shape gypsum board as the secondary slabs for air turbulence to increase air velocity, the number of mass flow rates have more efficient in the cooling process and fast the cooling process, the surface temperature was reduced by (4.5oC and 3.6 oC) with the mass flow rates of (3.5kg/s) and (2kg/s) respectively, this is due to moving air makes roof slab cool and loss the heat that transfers through the slabs, so using this technique for an exciting roof is a good choice","PeriodicalId":388003,"journal":{"name":"Journal of Studies in Science and Engineering","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133708713","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 paper emphasized the role of architecture in facilitating a therapeutic process for drug addicts in rehabilitation centre design as one of the solutions to this problem. Architectural spaces undoubtedly affect and influence the actions and attitudes of users. The study aims to integrate therapeutic techniques in rehabilitation centre design with enhanced spatial efficiency for holistic patient treatment to integrate them back into society. The methodology of the study is both theoretical and practical, involving a literature review, appraisal of case studies; observations, use of interviews and architectural design principles to formulate and produce a design model for a rehab centre in Calabar, Nigeria. Findings revealed that there are no known well-designed centres to rehabilitate victims of drug addiction in Calabar, Nigeria. The few centres available function as detention and discriminating spaces. The study concludes that rehab centres that focus on the therapeutic healing principles approach, which deals with patients’ mental, psychological, social and spiritual needs, should be developed in Calabar and other cities in Nigeria for swift rehabilitation of addicts.\u0000 ","PeriodicalId":388003,"journal":{"name":"Journal of Studies in Science and Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121128001","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}
