Abstract:
The adoption and widespread use of unmanned aerial vehicles (UAVs) is constantly increasing in many areas. This is due to the ability of drones to record and relay real-time video and images along with the ability to fly and carry cargo. However, when using drones, a number of problems arise, because outsiders can gain access to information transmission channels to meet their own needs. Information attacks on UAVs lead to significant consequences, including commercial and non-commercial losses. The purpose of this work is to study UAVs and their vulnerability and protection during flight. To a

Abstract:
Multi-input multi-output wireless mesh networks (MIMO WMNs) act as backbone broadband networks for ubiquitous access. Topology model is a crucial factor in interference avoidance, simplifying channel allocation, and discussing optimal scheduling and routing. Cartesian product of graphs (CPG) is introduced for MIMO WMN as a virtual topology. By putting orthogonal channels into different channel layer meshes, some conclusions are explored on channel allocation, routing and scheduling. A path coherent realization is composed of combinatorial edges over multiple channels for all hops. Some importa

Abstract:
The provision of mobile cloud service calls for a wireless access infrastructure that offers high bandwidth to mobile users. Among all enabling technologies, wireless mesh networks (WMNs) have the advantage of low deployment cost and widely available user equipments. To provide more bandwidth, access points in WMNs are commonly equipped with multiple wireless interfaces (radios) that can operate on multiple non-overlapping channels in parallel. The objective of channel assignments in a multi-channel, multi-radio MWN is to reduce co-channel interference experienced by links so as to increase ne

In this paper the authors are focused on channel identification and equalization for Multi-Carrier Code Division Multiple Access (MC-CDMA) system. For this, they identify the impulse response of two practical selective frequency fading channels called Broadband Radio Access Network (BRAN A and BRAN B) normalized by the European Telecommunications Standards Institute (ETSI). To identify the channel parameters, they have the positive definite kernels to build on algorithm. The simulations show that the presented method confirms the good performance for different SNR values. In part of equalizati

The use of the channel by unlicensed users should not result in more than acceptable interference level to the licensed users, if interference occurs. The sense and react strategy by unlicensed users sometimes does not lead to acceptable level of interference while maintaining an acceptable data transfer rate for the unlicensed users.

Abstract:
This method enables participants to create a visual map of the key resources and assets in their community, organisation, workplace etc, that are important for their wellbeing and thriving. It is designed to encourage marginalised groups to visually represent and reflect on these resources and the power relations that shape who accesses and controls resources. They map and rank the actors who have more/less power, control and access, and discuss the reasons behind these differences. Finally, a discussion of possible strategies and actions for change can be facilitated.

Abstract:
EnviroScience, Inc. (EnviroScience) was contracted by the National Park Service (NPS) to design and implement a study plan to inventory the headwater stream resources within the Cuyahoga Valley National Park (CUVA). The parameters and expectations of the study are described in a Statement of Work (SOW) developed by NPS staff (NPS, 2021) to collect and analyze data to guide decision-making in the development of management plans to protect these resources within CUVA. The headwater stream inventory was comprised of three components to evaluate the resources as follows: 1. habitat and biological

Abstract:
Bhutan’s schools maintained their relatively strong performance during the pandemic as access to remote learning, the opening of boarding facilities, and moves to prioritize education for secondary school pupils prevented performance gaps widening. This brief shows how Bhutan tried to minimize the impact of school closures on students, provided social safety nets to vulnerable households, and offered a mix of remote learning methods including television and internet. Analyzing exam grades for the Dzongkha national language, English, and science, it shows how the compensatory actions and steps

Abstract:
Remote sensing using Synthetic Aperture Radar (SAR) offers powerful methods for monitoring ground deformation from both natural and anthropogenic sources. Advanced analysis techniques such as Differential Interferometric Synthetic Aperture Radar (DInSAR), change detection, and Speckle Offset Tracking (SPO) provide sensitive measures of ground movement. With both the RADARSAT-2 and RADARSAT Constellation Mission (RCM) SAR satellites, Canada has access to a significant catalogue of SAR data. To make use of this data, the Canada Centre for Mapping and Earth Observation (CCMEO) has developed an au

Abstract:
In this paper, we examine whether acquiring citizenship improves the economic assimilation of Canadian migrants. We took advantage of a natural experiment made possible through changes in the Canadian Citizenship Act of 2014, which extended the physical presence requirement for citizenship from three to four years. Using quasi-experimental methods, we found that delaying citizenship eligibility by one year adversely affected Canadian residents' wages. Access to better jobs explains a citizenship premium of 11 percent in higher wages among naturalized migrants. Our estimates are robust to model

Abstract:
On August 13, 2017, the Philippine government enacted into law the Universal Access to Quality Tertiary Education Act (UAQTE) or Republic Act 10931, also known as Free Tuition Law, which mandates all public higher education institutions (HEIs) and government-run technical-vocational institutions (TVIs) to provide free quality tertiary education among eligible Filipino students. This long-awaited policy aims to increase access to tertiary education, particularly for students from poorer households. These goals are intended to be achieved through the implementation of four component programs und
