A Constrained Kalman Filter for Wi-Fi-Based Indoor Localization with Flexible Space Organization

This paper presents a constrained Kalman filter for Wi-Fi-based indoor localization. The contribution of this work is to introduce constraints on the object speed and to provide a numerically optimized form for fast computation. The proposed approach is suitable to flexible space organization, as in warehouses, and when objects can be spun around, for example barcode readers in a hand. We experimented with the proposed technique using a robot and three devices, on five different journeys, in a 6000 m2 warehouse equipped with six Wi-Fi access points. The results highlight that the proposed approach provides a 19% improvement in localization accuracy.

Constructing Culturally-Authentic Differentiated Access Points Using the Content Imperatives

The need to create culturally authentic and specific learning experiences is a call to action that all teachers must answer. Current definitions of differentiation either avoid or exclude topics of culture and race. These definitions are incomplete and must be expanded if the needs, interests, abilities, and cultural assets of gifted learners are to be addressed in a classroom. Under this expanded definition, differentiation strategies must be culturally authentic and purposefully integrated into the opportunities provided to gifted learners. It is incumbent upon teachers to reorient differentiation strategies they employ with gifted and advanced learners, so they become culturally authentic and contextually relevant. This chapter provides the reorientation of one differentiation strategy: the content imperatives. This chapter (1) defines the content imperatives, (2) demonstrates how they can be used as the catalyst for honoring the funds of knowledge that students bring into any learning experience, and (3) creates culturally-authentic access points into content for all learners.

Modeling in the OMNET ++ environment of connection processes in Wi-Fi networks

Предложен подход к разработке в среде OMNeT++ INET простейшей имитационной модели инфраструктурного режима функционирования Wi-Fi сети, который позволяет проводить подробный анализ функционирования таких сетей, а также строить и анализировать временные диаграммы взаимодействия всех элементов сети. Разработанную модель можно использовать как базовую для формирования более сложных моделей с произвольным числом мобильных клиентов, позволяя определять необходимое количество точек доступа и мест их размещения для обеспечения полноценного покрытия зоны мониторинга лесной территории. An approach to the development in the OMNeT ++ INET environment of the simplest simulation model of the infrastructure mode of Wi-Fi network operation is proposed, which allows a detailed analysis of the functioning of such networks, as well as to build and analyze the time diagram of the interaction of all network elements. The developed model can be used as a base for the formation of more complex models with an arbitrary number of mobile clients, allowing you to determine the required number of access points and their locations to ensure full coverage of the monitoring area of the forest area.

Mindfulness Access Points in General Music: Singing, Breathing, and Self-Awareness

The purpose of this column is to promote the use of focused breathing and singing as access points to improved student self-awareness in the general music classroom. Singing is a holistic activity with the healing potential to improve and transform many traumatic life experiences endured by our students. Similarly, mindfulness breathwork is a holistic approach used to enhance self-awareness in the moment and can reduce anxiety. Both pursuits have the potential to help students overcome difficulties of fear, stress, and anxiety. Both practices expose participants to new ways of understanding themselves and the world around them while creating important access points to mindfulness and self-awareness.

Will Online Banking Sustain in Bhutan Post Covid-19? A Quantitative Analysis of The Customer E-Satisfaction and E-Loyalty in The Kingdom of Bhutan

Online Banking has received a boost during Covid 19. It is believed that the cultured sector of the population has quickly adopted online banking since the outbreak of the virus. Online banking not only provides a platform for performing financial transactions but also acts as a medium of communication between the bank and the customer. Unlike rest of the world, perception of online banking came slightly late in the Kingdom of Bhutan, which already had a good network of banking access points for its populace, enabling the physical banking. However, due to lockdown observed in the aftermath of Covid-19, the online banking has established development in the country. In the present study, the researchers have confidence in that if the customer satisfaction can be ensured amongst the existing users of the online banking, then they will become dependable to such platform and would continue even in the post Covid-19 time. This study is imperative as the banking system of Bhutan has spent a significant number of resources in obtaining and implementing the online banking system, and sustainability of the system will be a point of concern for the decision makers.

Wireless Terrestrial Backhaul for 6G Remote Access: Challenges and Low Power Solutions

Despite developments in communication systems over the last few decades, a digital divide exists in the unconnected part of the world. The latter is characterized by large distances to internet access points, underdeveloped infrastructure, sparse populations, and low incomes. This concern of digital divide is raised in the sixth generation’s (6G) initial vision as an extremely important topic. However, it is important to understand affiliated challenges and potential solutions to achieve this vision. Motivated by the recent backhaul link forecasts that expect a dominance of the microwave technology within the backhauling market, this paper studies the potential of a low-power terrestrial microwave backhaul from the sufficient-data-rate and solar powering perspective. Competing technologies (e.g., fiber) may not be energy efficient and commercially viable for global connectivity. Since rural and remote areas may not have grid power, we look at the viability of alternative sustainable sources, in particular solar power, to power the wireless backhaul in 6G. In addition, we also explore services for the operators and users to use the system efficiently. Since the access points are connected to backhaul, we also compare the two prominent solutions based on low-power small-radius cells and a mega-cell that covers a large area and show insights on the power autonomy of the systems. In the end, we propose directions for research and deployment for an inclusive connectivity as a part of future 6G networks.

Pengembangan Sistem Pemantauan dan Deteksi Serangan pada Ekosistem Rumah Cerdas

It is predicted that the growth of smart devices installed in the smart home ecosystem will increase in the future. Smart devices that are connected to each other using wired or wireless networks that have the potential for security holes are attacked by threat actors. Whereas a house is a place that provides comfort for its residents. An attack on the smart home ecosystem allows the operation of the smart home ecosystem to be disrupted or personal information stolen to be used by irresponsible parties. To face the high wave of smart home implementation in the future with potential security holes that always accompany it. This is in accordance with the principle that no system is 100% secure. In this study, attacks on wireless networks can be detected as anomalous traffic. Monitoring and detection in the smart home ecosystem involves supporting components such as sensors, access points, gateway collectors and analysis stacks.
