Facilitating Internet of Things on the Edge

The evolution of electronics and wireless technologies has entered a new era, the Internet of Things (IoT). Presently, IoT technologies influence the global market, bringing benefits in many areas, including healthcare, manufacturing, transportation, and entertainment. Modern IoT devices serve as a thin client with data processing performed in a remote computing node, such as a cloud server or a mobile edge compute unit. These computing units own significant resources that allow prompt data processing. The user experience for such an approach relies drastically on the availability and quality of the internet connection. In this case, if the internet connection is unavailable, the resulting operations of IoT applications can be completely disrupted. It is worth noting that emerging IoT applications are even more throughput demanding and latency-sensitive which makes communication networks a practical bottleneck for the service provisioning. This thesis aims to eliminate the limitations of wireless access, via the improvement of connectivity and throughput between the devices on the edge, as well as their network identification, which is fundamentally important for IoT service management. The introduction begins with a discussion on the emerging IoT applications and their demands. Subsequent chapters introduce scenarios of interest, describe the proposed solutions and provide selected performance evaluation results. Specifically, we start with research on the use of degraded memory chips for network identification of IoT devices as an alternative to conventional methods, such as IMEI; these methods are not vulnerable to tampering and cloning. Further, we introduce our contributions for improving connectivity and throughput among IoT devices on the edge in a case where the mobile network infrastructure is limited or totally unavailable. Finally, we conclude the introduction with a summary of the results achieved

Desarrollo de un modelo de simulación de realidad virtual usando un dispositivo portable en un entorno virtual

The world population is aging, The quality life in elder people deteriorates with age, this is because of the sedentary lifestyle in which they live, consequently these countries must adapt much more rapidly to this aging. Therapy and Physical activity helps to improve health and well-being in the elders, bringing longevity and improves their life quality. The Technology has been used as a tool in various fields and there are some applications that have been developed to encourage sports through entertainment. Nintendo Wii and Kinect games had a positive impact on the overall well-being of the elderly, compared to a other group that played traditional board games. The life quality of the elderly is impaired by the lack of physical activity, entertainment and lack of memory use. This work aims to solve this problem with the implementation of a system that promotes physical activity through body movements, generate entertainment through the control of a drone in a virtual environment and promote memory through remembering movement patterns that is due perform to be able to control the virtual Drone correctly. This work makes use of wireless devices, wearable, light and with IMU sensors integrated in order to generate a body area network system that scans each arm movement and sends that information through Bluetooth Low Energy (BLE) technology to a virtual environment and control an UAV (Unamed Aereal Vehicle) remotely. The proposed system includes a 3D simulator that uses VR glasses for an immersive visualization in a virtual world, 2 Raspberry Pi devices with Sense HAT board integrated as hand controls, these plates are equipped with an IMU sensor that is responsible for the arms movement monitoring. This proposal allows an interconnection of portable devices through wireless technology and combine them with immersive virtual environments to generate a system that emulates the control of a Drone in a simulated environment. In order to adapt the system and focus on older people, it is proposed to implement 2 visualization modes and 2 difficulty modes, the visualization modes determine the perspective in which the user looks at the environment while the user controls the Drone, The First perspective, is defined by a third person camera system, where the user is layers of watching the Drone while controlling it and the second mode corresponds to a first person camera system, where the user's eyes are in the same drone position, this mode allows appreciate the environment in a better way, but does not allow to visualize the UAV. In the performed tests, each user had his / her own preferences, some of them liked to use the simulator with first persona camera configuration and others with third person camera configuration. this way the system is designed to adapt to the visualization mode of each individual. With respect to the difficulty modes, the simulator offers the possibility to use the maneuver the drone through 2 mechanisms, in easy mode, where the user only needs to make 4 movements between both hands and the difficult mode where the user requires 6 movements between both hands in order to have a total drone control, this allows the user to develop cognitive skills (Eye-hand coordination) and improve physical and mental health, when using this system. Through the tests of latency, it is determined that the transmission of data through Bluetooth Low Energy is extremely fast which means that the movements of hands that the user performs become real motions of the Virtual Drone in real time. A real time simulator is a system that offers reaction times similar to reality, this determines the efficiency of the simulator when it is used as training before using a real Drone. Performed tests with older adults reveal an evolution of skills when using the system progressively in each of the different modes of use. The interest, the entertainment and the physical activity that the system promotes in the elderly, is enough to improve their quality of life by contributing in the reduction of the sedentary, promoting the physical activity and mental state. To achieve the implementation of this system we propose a parallel development of a native Android application that makes use of the same system of body area networks of sensors to maneuver a real dron (Phantom 4) using only the movement of hands, with the object of validate the functions and movements of the virtual drone based on the movements of the real dron under the same control mechanism

Cognitive Decay And Memory Recall During Long Duration Spaceflight

This dissertation aims to advance the efficacy of Long-Duration Space Flight (LDSF) pre-flight and in-flight training programs, acknowledging existing knowledge gaps in NASA\u27s methodologies. The research\u27s objective is to optimize the cognitive workload of LDSF crew members, enhance their neurocognitive functionality, and provide more meaningful work experiences, particularly for Mars missions.The study addresses identified shortcomings in current training and learning strategies and simulation-based training systems, focusing on areas requiring quantitative measures for astronaut proficiency and training effectiveness assessment. The project centers on understanding cognitive decay and memory loss under LDSF-related stressors, seeking to establish when such cognitive decline exceeds acceptable performance levels throughout mission phases. The research acknowledges the limitations of creating a near-orbit environment due to resource constraints and the need to develop engaging tasks for test subjects. Nevertheless, it underscores the potential impact on future space mission training and other high-risk professions. The study further explores astronaut training complexities, the challenges encountered in LDSF missions, and the cognitive processes involved in such demanding environments. The research employs various cognitive and memory testing events, integrating neuroimaging techniques to understand cognition\u27s neural mechanisms and memory. It also explores Rasmussen\u27s S-R-K behaviors and Brain Network Theory’s (BNT) potential for measuring forgetting, cognition, and predicting training needs. The multidisciplinary approach of the study reinforces the importance of integrating insights from cognitive psychology, behavior analysis, and brain connectivity research. Research experiments were conducted at the University of North Dakota\u27s Integrated Lunar Mars Analog Habitat (ILMAH), gathering data from selected subjects via cognitive neuroscience tools and Electroencephalography (EEG) recordings to evaluate neurocognitive performance. The data analysis aimed to assess brain network activations during mentally demanding activities and compare EEG power spectra across various frequencies, latencies, and scalp locations. Despite facing certain challenges, including inadequacies of the current adapter boards leading to analysis failure, the study provides crucial lessons for future research endeavors. It highlights the need for swift adaptation, continual process refinement, and innovative solutions, like the redesign of adapter boards for high radio frequency noise environments, for the collection of high-quality EEG data. In conclusion, while the research did not reveal statistically significant differences between the experimental and control groups, it furnished valuable insights and underscored the need to optimize astronaut performance, well-being, and mission success. The study contributes to the ongoing evolution of training methodologies, with implications for future space exploration endeavors

Enhanced Living Environments

This open access book was prepared as a Final Publication of the COST Action IC1303 “Algorithms, Architectures and Platforms for Enhanced Living Environments (AAPELE)”. The concept of Enhanced Living Environments (ELE) refers to the area of Ambient Assisted Living (AAL) that is more related with Information and Communication Technologies (ICT). Effective ELE solutions require appropriate ICT algorithms, architectures, platforms, and systems, having in view the advance of science and technology in this area and the development of new and innovative solutions that can provide improvements in the quality of life for people in their homes and can reduce the financial burden on the budgets of the healthcare providers. The aim of this book is to become a state-of-the-art reference, discussing progress made, as well as prompting future directions on theories, practices, standards, and strategies related to the ELE area. The book contains 12 chapters and can serve as a valuable reference for undergraduate students, post-graduate students, educators, faculty members, researchers, engineers, medical doctors, healthcare organizations, insurance companies, and research strategists working in this area

Semantic location extraction from crowdsourced data

Crowdsourced Data (CSD) has recently received increased attention in many application areas including disaster management. Convenience of production and use, data currency and abundancy are some of the key reasons for attracting this high interest. Conversely, quality issues like incompleteness, credibility and relevancy prevent the direct use of such data in important applications like disaster management. Moreover, location information availability of CSD is problematic as it remains very low in many crowd sourced platforms such as Twitter. Also, this recorded location is mostly related to the mobile device or user location and often does not represent the event location. In CSD, event location is discussed descriptively in the comments in addition to the recorded location (which is generated by means of mobile device's GPS or mobile communication network). This study attempts to semantically extract the CSD location information with the help of an ontological Gazetteer and other available resources. 2011 Queensland flood tweets and Ushahidi Crowd Map data were semantically analysed to extract the location information with the support of Queensland Gazetteer which is converted to an ontological gazetteer and a global gazetteer. Some preliminary results show that the use of ontologies and semantics can improve the accuracy of place name identification of CSD and the process of location information extraction

Achieving zero accidents: a study of the influences of Indonesian national and military organisational cultures on aviation safety

Accident prevention in the aviation industry requires not only a good safety management system (SMS) but also the right safety culture that makes safety systems work. Research shows that safety culture in an organisation is greatly influenced by national and organisational cultures. However, much of the safety research has focused more on safety climate which measures perceptions and attitudes of workers in regard to safety. Moreover, most of the safety climate research has been conducted using a quantitative approach, which cannot uncover the basic assumptions of the culture itself. In addition, the impact of national and military culture on aviation safety has not been addressed in the small amount of safety climate research which has been conducted in military organisations to date. One of the rationales for conducting this study is a growing concern regarding aircraft accidents that occur every year even though Indonesian military organisations have implemented safety management systems. This research was intended to examine the influence of Indonesian national culture and military organisational culture on aviation safety, particularly in the adoption and implementation of the SMS. The adoption and the implementation of an SMS have not made a significant impact since the organisation still experiences aircraft accidents. As the SMS is predominantly based on Western concepts of management, this study attempted to identify the characteristics of the Indonesian national and military organisational culture that influence the implementation of the program. Furthermore, this study investigated and identified the perception and behaviour of the military personnel and how management manages safety issues within the organisation. This study employed a qualitative research design, comprising multiple case studies. An ethnography-style research approach was adopted in order to acquire an understanding of the basic assumptions of a culture that drive people to a particular behaviour. In-depth semi-structured interviews, observations, and document analysis were the techniques used to gather data. Twenty-seven military personnel from four different operational air units participated in this research. The participants come from various backgrounds in terms of corps, ranks, and positions within their respective units. Thematic analysis was applied in this study and six phases of analysis, proposed by Braun and Clarke (2006) and Clarke et al. (2015), were used as guidance. Analysis of the findings showed that the Indonesian military culture has been much influenced by its national culture. Moreover, the unique characteristics of the Indonesian national and military cultures have significant influences on military aviation safety. Several characteristics of the Indonesian national culture, most of which have their origin in Javanese culture, such as hierarchical structure, authoritarian structure, rukun/harmony, unggah ungguh/manner, sungkan/reluctant, and asal bapak senang (ABS)/as long as the boss is happy, have impeded the implementation of the SMS and the promotion of safety culture. Similarly, some characteristics of the Indonesian military organisational culture such as punishment and reward, blame culture, class/rank structure, and siap/can-do culture are factors that obstruct the promotion of a safety culture and the implementation of an SMS. In addition to those cultural factors, the lack of safety education and training, and various perceptions of what constitutes safety have created a situation in which individual safety awareness has declined. However, one interesting finding reveals that there is a tendency for rules and procedures to become another alternative method for dealing with uncertainty. The unit personnel believe that rules and procedures can assist them to cope with uncertainty, in addition to their religious and spiritual beliefs. This study offers some contributions to knowledge and has the capacity to provide recommendations for Indonesian military organisation regarding its safety program. First, this is an empirical study that provides insight into how the cultural factors influence the implementation of the safety management systems and the promotion of a safety culture in Indonesia. Through this study, an in-depth understanding was acquired of the impacts of the unique military organisational culture on the adoption of Western concepts of management. It is expected that this study will extend various research on safety culture. Second, the findings of the study indicate that one cultural dimension - coping with ambiguity or uncertainty avoidance - is not consistent with Hofstede and GLOBE’s description. In addition to religious and spiritual beliefs, the findings indicate that the increased use of rules and clearly-defined procedures are an additional means of coping with uncertainty. Third, this study recommends that the Indonesian military organisation integrate cultural factors into its organisation safety system, which is essential if the organisation is to successfully implement the SMS, promote a safety culture, and improve its safety
