Various technical studies by 3GPP have addressed NTN-based implementations and have significantly studied satellite-based scenarios. However, the study does not sufficiently address HAPS or multi-HAPS based scenarios specifically. Though HAPS, is captured under Unmanned Aerial Systems (UAS), it has unique operational realities that set it apart from other NTN platforms. For instance, HAPS come in different variants of fixed-wing, balloons and airships. This paper highlights the need for expanded studies specifically aimed at HAPS for more seamless integration. The work also analyses the Doppler effect associated with fixed-wing HAPS systems to further demonstrate how operational scenarios may differ for these platforms and the need for targeted studies. HAPS is expected to contribute significantly to the NTN-based implementations and may require more specialised considerations within the 3GPP NTN technical specification process, especially for 5G and beyond 5G (B5G) networks.","PeriodicalId":154311,"journal":{"name":"International Journal of Information, Communication Technology and Applications","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127243847","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}

Many disaster management systems often lack the capability to cope with the complexity and uncertainty. In this investigation on the use of ICTs in natural disaster management we discuss the disasters that Kabale has experienced and how ICTs are used in the disaster management processes. The paper concludes that although there are some types of ICTs used, ICT infrastructure is still under-developed in Kabale district. There is a need to increase the level of ICT usage such that natural disaster management can realize its full potential.","PeriodicalId":154311,"journal":{"name":"International Journal of Information, Communication Technology and Applications","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114330418","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}

This paper reviews the extraction of evidence from virtualized RAM in the Cloud context on two virtual machines. Such evidence informs network system fault correction, and attack diagnosis. The contribution of this research is to promote an awareness of valuable evidence held in Cloud virtual machines, where it is located, and the extraction tools kits required. A challenge for network investigators is the variation in distributed network architecture and protocols. There is little consistency in the Cloud environment beyond proprietary dominance of Cloud services, and vendor virtualization provisions. This exploratory research takes up this challenge and demonstrates a working solution to the extraction of data in Cloud distributed networks.","PeriodicalId":154311,"journal":{"name":"International Journal of Information, Communication Technology and Applications","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127434003","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}
