Exploiting high-precision AoA estimation method using CSI from a single WiFi station

The accuracy of estimating the angle of arrival (AoA) using wireless fidelity (WiFi) channel state information (CSI) has been a topic of intense interest in the fields of the Internet of Things, location-based services, etc. We propose a high-precision method of AoA estimation of the direct path (DP) using WiFi CSI from a single station. It contains three stages: data preprocessing, AoA-time of flight (ToF) joint estimation for all paths, and the DP's AoA estimation. Firstly, phase calibration, linear transform, and multiple-layer filtering are accordingly conducted after CSI collection in the preprocessing stage to output the denoised CSI. Then, the AoA and ToF values for all paths are simultaneously obtained utilizing a spatial smoothing multiple signal classification (MUSIC) algorithm. Finally, the density-based spatial clustering for noise applications (DBSCAN) algorithm divides all the AoA and ToF values into several clusters. The target cluster that meets the requirements of maximum counts and minimum mean ToF is subsequently selected. The weighted centroid AoA value of the target cluster is regarded as the AoA of the DP. AoA estimation experiments using different sampling packets are conducted in a small conference room with an Intel 5300 network interface card along a straight line. The proposed method could recognize the DP with a rate of 100 percent and estimate the AoA of the DP with a mean absolute error of 2° and root mean square error of 2.82° Compared with SpotFi and hierarchical clustering–logistic regression systems, the proposed method improves AoA estimation accuracy by at least 75 %. Therefore, the proposed method could achieve a high-precision estimation of the AoA of the DP in the case 26 of different short distances.

Can the infection risk in elevators be negligible? A comparative study of airborne infection probability in elevators and conference rooms

People in crowded and poorly ventilated elevators are at risk of respiratory infection. However, due to the short duration of the elevator ride, the transmission of respiratory diseases in elevators does not get enough attention. To evaluate the infection risk, this study investigated the airborne transmission of respiratory diseases in the hospital elevator by comparison to the conference room. A validated computational fluid dynamics (CFD) model was adopted to simulate airflow, temperature and tracer gas dispersion in the elevator and conference room. We used Wells-Riley model to evaluate the infection probability of the susceptible persons. In addition, the influences of source patient posture and ventilation strategy on the transmission of tracer gas were analyzed. The results showed that the infection probability in the elevator with 5 min (average 2.70%) was higher than that in the conference room with 50 min (average 1.77%). The effects of source patient posture and ventilation strategy on the infection probability in the elevator were more significant than those in the conference room. Local air circulation could gather the tracer gas inside a confined space in the elevator and led to a high infection probability. The infection risk of respiratory diseases in the elevator was non-negligible.

Impact of contextual and lip-sync-related visual cues on speech intelligibility through immersive audio-visual scene recordings in a reverberant conference room

Recent hearing research has benefitted from the latest Virtual Reality systems that allowed the reproduction of immersive Audio-Visual scenarios to achieve more ecological listening tests. Indeed, efforts have been spent to identify the aspects that convey actual ecological validity, particularly investigating the effects of visual cues and self-motion on Speech Intelligibility through tests mainly based on simulated scenes. However, work must still be addressed when sceneries developed through real recordings inside reverberant environments are concerned. This study used 3rd-order ambisonics recordings and stereoscopic 360° videos inside a reverberant conference hall to create three virtual audio-visual scenes where speech intelligibility tests were performed, introducing informational noise from different angles. A 16-speaker spherical array synced with a headmounted display was used to administer the immersive tests to 50 normal-hearing subjects. Firstly, tests only composed of the auditory scenes were compared, based on the achieved scores, with tests also providing contextual and positional source-related visual cues, both with and without self-motion, for a total of four different test configurations. Then, to complete the investigation of the visual cues' impact on speech intelligibility, ten normal-hearing subjects were recruited to performaudio-visual tests incorporating lip-sync-related visual cues for the target speech.

Original Research: Alarm Fatigue: Exploring the Adaptive and Maladaptive Coping Strategies of Nurses.

To improve patient safety, hospitals use alarm notification systems to increase nurses' real-time situational awareness of a patient's condition. Such alarms are critical to nurses' clinical decision-making and prioritization, thus helping to improve patient care and care efficiency. But the frequent and often simultaneous ringing of alarms, including many that are false, nonemergent, or nonactionable, has led to overwhelm, alarm distrust, and desensitization, resulting in alarm fatigue. This study aimed to explore oncology nurses' lived experiences with alarms and the adaptive and maladaptive strategies they use to cope with alarm fatigue. This qualitative, phenomenological study was guided by the theoretical framework of the Roy Adaptation Model. A purposive sample of nine nurses was recruited from two oncology units at a large midwestern Magnet hospital in the United States. Qualitative data were collected using a six-question, semistructured interview guide. Interviews were conducted either face-to-face in a private conference room on the unit or via the online videoconferencing platform Zoom. Data analysis yielded five themes, the most prominent being the high volume and frequency of alarms . Nurse participants reported adopting more maladaptive than adaptive coping strategies. Overall, they felt that the high frequency of false, nonemergent, and nonactionable alarms disrupted their workflow and contributed to a general desensitization to alarms. This study's findings offer valuable insight into the problem of alarm fatigue among nurses. Practical measures are urgently needed to reduce nurses' cognitive overload; shift nonnursing responsibilities to other staff; and implement efficiency-focused process changes, such as reengineering workflows to minimize interruptions. Every effort should be made to redesign protocols to reduce alarm fatigue, including by decreasing the number of false, nonemergent, and nonactionable calls and alarms.

Optimal operation strategy predictive control for an integrated radiant cooling with fresh air system based on machine learning

Radiant cooling systems are widely valued for their great comfort and energy-saving potential. However, they still face the risk of condensation in the early stages of operation, especially in case of random occupancy and intermittent operation. This study aims to avoid unacceptable discomfort durations in randomly occupied rooms that installed integrated radiant cooling and fresh air system while consuming as little energy as possible. This paper firstly compares the effects of adopting only the setback or standby cooling strategy in a randomly occupied conference room by simulation. The simulation results demonstrate the necessity for predicting optimal operation strategy. Subsequently, optimal operation strategy predictive models were built using three machine learning algorithms on three datasets. The evaluation results of the models indicate the feasibility of using data from neighbouring cities to improve the generalisation ability of the target city model. Finally, the best one of models was used to predict optimal operation strategy and achieved good results: discomfort durations of 97.56% of the conferences were within the acceptable range. Additionally, compared to only adopting the standby cooling strategy, the radiant cooling system operating time was reduced by 8.88%, and the total energy consumption was reduced by 28.85 kWh. In this study, a model to predict optimal operation strategy is proposed. By simulating and analysing from both comfort and energy perspectives, the optimal operation strategy predictive control method effectively limits the discomfort duration and reduces energy consumption and radiant system runtime. This study provides an example of practical engineering and machine learning applications for radiant cooling systems.

Live Streaming of the Professor's Ward Rounds in Undergraduate Neurology Education: Usability Study.

Although neurology department ward rounds are among the most important medical education exercises in Japan, they have several issues. Patients may find it unpleasant to undergo repeated neurological tests, especially when in the presence of several students. Only the front row of students can closely observe the examination findings; moreover, students were prohibited from contacting patients altogether during the COVID-19 pandemic. One possible solution is to use commercial videoconferencing systems. However, Japanese patients are reluctant to have their medical information or video footage of them sent outside of the hospital via the internet. The study aimed to confirm the feasibility of conducting remote teaching rounds using an in-house web conferencing system in which the patients' personal data are securely protected. This study also explored whether using remote rounds alongside face-to-face participation would enhance learning. We created an on-premises videoconferencing system using an open-source app. To perform video ward rounds, the professor wore a wireless microphone while leading routine in-person rounds and the attending physician carried a tablet device linked to a web conference, allowing students in another room to watch the rounds on a live stream. In total, 112 of 5th-year students who entered their 1-week neurology rotation between 2021 and 2022 were instructed to participate in 1-hour in-person and remote rounds. Students were given questionnaires to evaluate their satisfaction and the educational effects of the remote rounds. The remote ward rounds were conducted easily with no interference with the in-person rounds, nor any complaints from the patients. Each examination technique was explained by another teacher to the students who participated in remote rounds in the conference room. Characteristic neurological findings, such as plantar reflexes (Babinski sign), which are usually seen only by close observers during in-person rounds, could be visualized under magnification by all students. The postexperience survey (82/112, 73% response rate) showed that the mean score of participants' satisfaction was 3.94 (SD 0.83; excellent 5 and poor 1). No participant scoring 1 was noted. The proportion of students who observed 6 representative abnormal neurological findings (Babinski sign, hyperreflexia, cerebellar ataxia, involuntary movement, muscular weakness, and abnormality in sensory examination) increased by 22% (18/82, range 13-24) compared to in-person rounds alone. When self-rating the learning value, 43% (35/82) of the students answered that remote rounds are equally as valuable as in-person rounds, while 32% (26/82) preferred remote rounds. Live-streaming of neurology ward rounds using a secure in-house web conferencing system provides additional learning experience without concerns regarding leakage of patient information. This initiative could enhance neurology learning before entering a clinical clerkship.

Culinary Medicine and Teaching Kitchens: Dietitians Leading Innovative Nutrition Training for Physicians.

The objective of this evaluation was to determine the impact of a pop-up Teaching Kitchen (TK) at a national cardiovascular conference. The 60-minute session was hosted in a hotel conference room and led by two registered dietitians. Participants prepared 12 recipes, enjoyed a family-style meal, and explored nutrition behaviour change strategies for patients. Using Likert-scaled and open-ended questions, pre-/post-online surveys assessed change in perceived nutrition counselling skills, attitudes, and confidence; post-survey also assessed effectiveness of session components and further training needs. Pre-survey response was 72% (18/25). Twenty-one participants attended the event (14 pre-registrants, six from waitlist, and five drop-ins); 81% completed the post-survey. Positive shifts were reported in nutrition competence, particularly attitudes towards using recipes in nutrition counselling, and increased skills and confidence discussing eating on a budget and SMART (Specific, Measurable, Achievable, Relevant, and Time-Bound) goal setting with patients. Components of the TK session that enhanced nutrition competence were key patient messages and the shared meal. Preparing and eating together in a hands-on format was most enjoyable. Promoting healthy eating behaviours requires understanding the complexity of individual and societal food literacy. With high physician interest, dietitians are well positioned to deliver culinary medicine interventions and support physicians' confidence in health promotion and chronic disease prevention and management.

(Invited) Fruitful and False Analogies between Polymer Electrolyte Fuel Cells and Electrolyzers

In the past 20 years polymer electrolyzer membrane fuel cells (PEMFCs) received great attention as a clean alternative for powering mobility and stationary applications. Resultingly, there has been a rich amount of research by public, private and university investigators particularly focusing on membranes, catalysts, transport and cost. Yields of great advances were made, though scant attention was given to the generation of this hydrogen and polymer electrolyte membrane water electrolysis (PEMWE) was the neglected stepsister, sentenced to back chapters, footnotes, and small conference rooms. Now however the opportunity for hydrogen generated from renewables, "green hydrogen" has been widely seen as an opportunity to not only provide hydrogen for these PEMFC applications, but also seemingly intractable CO2 emitters as ammonia generation and steel and petroleum refining. As numerous government agencies have announced eye-popping targets for green electrolysis and the complementary research funding, the temptation is to take the beautiful evening gown woven of PEMFC research and adorn the overlooked stepsister. .Zealous PEMFC researchers have not surprisingly reversed course and focused attention on making, rather than consuming hydrogen. Exploitation of the PEMFC and PEMWE analogy is tempting, as many of the materials and reactions are the same or similar. Noteworthy, there are the polymer electrolyte membrane, expensive PGM catalysts, a very fast hydrogen reaction and very slow oxygen reaction. Yearning for faster kinetics and facile heat management, both also have pushed operation to higher temperatures and suffer the accelerated degradation that goes with it. Using these analogies has has generated some benefits, particularly in lower catalyst loading and conductive membrane resistance. Keeping in mind the differences is key however, as PEMWE will generally need to operate at much higher currents, under higher pressures, for far longer durations.This talk will look at what PEMWE has and has the potential to learn from PEMFC research. We will look at materials, their key aspects and how optimizing for each is different, with a focus on costs, the use of hydrocarbon materials, chemical and mechanical durability strategies and recycling. Use cases will also be explored, particularly how the need for high hydrogen production pressures (>30 bar) changes the electrode assembly as well as the balance of stack.

Perancangan Tata Udara Menggunakan Metode Cooling Load Tempreture Difference (CLTD) Pada Studi Kasus Proyek X

This research is related to the design of air conditioning using the Cooling Load Temperature Difference (CLTD) method in the case study of Project X. One of the methods used is the Cooling Load Temperature Difference (CLTD) method. This method considers factors such as wet-bulb temperature, dry-bulb temperature, and air velocity to calculate the room cooling load. This research applies the CLTD method to a case study project in Jakarta with an air conditioning system in office buildings. This case study provides an example of the practical application of the CLTD method that is beneficial for practitioners in the field of air conditioning engineering. To implement the CLTD method, data from field studies such as room conditions, temperature, and humidity of the room and environment are needed. Next, calculations are made using the CLTD formula adjusted to the position of the sun in each room. The CLTD calculation results show that the highest sensible load is in the Boardroom, while the highest latent load is in the Conference Room. The design of the cooling system with the CLTD method shows optimal results and meets the requirements. The AC capacity calculated accurately and considering K4L factors results in an efficient, safe, and environmentally friendly cooling system.

Multi‐band millimetre wave indoor directional channel measurements and analysis for future wireless communication systems

AbstractSingle‐input single‐output (SISO) three‐dimensional (3D) wideband indoor directional measurements collected in a factory environment and an office environment at 38 and 70 GHz are presented. 3D single‐input multiple‐output (SIMO) dual polarised measurements with 1 × 2 antenna configurations were also carried out in a meeting room, a conference room, and an office room at the 60 GHz band. The measurements cover both azimuth and elevation by rotating the directional antenna (RDA) at the receiver side. Different statistical channel parameters such as power delay profile, power angle profile, root‐mean‐square delay spread, angular spread, and path loss were estimated for different possible antenna orientations between the transmitter and the receiver, which include line‐of‐sight, obstructed line‐of‐sight, and non‐line‐of‐sight. The polarisation effects on path loss models and the delay and angular spread models based on the surface area of the environment are studied. The results will be valuable for the design of indoor millimetre wave cellular networks.

Investigation of a DNA tagged aerosol tracer method for In Situ evaluation of germicidal UV air cleaner effectiveness

Transmission of respiratory pathogens occurs primarily in indoor settings, interventions to reduce the risk of their transmission include increases in outdoor air introduction, filtration, and ultraviolet germicidal irradiation (UVGI). However, validating these interventions is challenging, particularly in actual applications. This study introduces an aerosol tracer system utilizing DNA as tracer molecule, aimed at quantitative characterization of the performance of indoor air cleaning systems. Two DNA tracers, designed one to be relatively UV-resistant and another relatively UV-sensitive, were employed to assess air quality changes related to filtration and ventilation and the contributions of UVGI fixtures in various built environments. We conducted controlled UV exposure experiments of DNA-tagged tracers on foil coupons, aerosolization studies in a test chamber, and in a commercial building conference room. The DNA tracer results provided insights at the point of sampling into the effects of complex airflow dynamics. Additionally, a way to scale the DNA tracer results to MS2 bacteriophage is proposed. Four distinct UV devices challenged with MS2 in a chamber test produced equivalent clean airflow rates of 13–147 CFM. Scaled equivalent clean airflow rates in a commercial building setting using the UV-sensitive tracer varied from 47 percent less to 101 percent more than the chamber results, possibly due to differences in airflow patterns, equipment configuration, and other factors. Our findings provide quantitative understanding of the interaction between UV-sensitive aerosols and the built environment, with implications for environmental monitoring, measuring UVGI fixture impact in field settings, and addressing current technologies limitations for assessing UVGI disinfection efficacy.

Improvement of Dynamic Characteristics of Purpose-Built Vehicles Using Semi-Active Suspension System.

The diversification of mobility into services such as smart stores and conference rooms has accelerated the development of purpose-built vehicles (PBVs)-vehicles designed for specific purposes that utilize an extended electric vehicle chassis and autonomous driving technology. Despite the standards on speed bump dimensions stipulated by the National Land Transportation Act of the Republic of Korea, real-world speed bumps feature varying widths and heights that deviate from these standards. In this study, a velocity equation was derived via regression analysis to achieve the desired dynamic characteristics for a PBV passing over speed bumps with varying shapes through two types of semi-active suspension control: proportional-integral-differential (PID) and linear-quadratic-regulator (LQR). For a cargo-transport PBV, the PID and LQR controllers increased the velocity by 23.74% and 50.74%, respectively, under different speed bump widths and by 19.44% and 38.31%, respectively, under different speed bump heights. Moreover, an analysis of the vibration dose value (VDV), an indicator of ride comfort, revealed that the VDVs calculated using the velocity equation were within an acceptable error range of 10% above the target VDV. These findings provide insights into the speed control required for different types of autonomous PBVs to ensure ride comfort, as well as minimize the driving duration, depending on the specific purpose of the vehicle.

Irradiate the knowledge gap: Empowering residents for blood product selection at Albany Medical Center.

e23236 Background: Transfusion-associated graft versus host disease (ta-GvHD) poses risks for immunocompromised patients. Indications for irradiated blood products include hematological malignancies and bone marrow transplant cases. In instances of severe acute pancytopenia, the initial contact at the emergency room (ER) is typically a nurse, followed by the ER physician. Patients referred from the local private practice, New York Oncology and Hematology (NYOH) office to our local hospital, Albany Medical Center (AMC), often bring comprehensive paper charts, but those coming directly from home frequently lack necessary documents, relying on the medical teams' expertise to ensure appropriate blood product selection. We aim to improve understanding of transfusion products and their indications. Methods: An initial pre-survey questionnaire was sent to internal medicine residents. Of the 33 responses received, 87.9% were aware of the need for irradiated blood products in hematological malignancies, 66.6% knew it was not required for solid tumors, and only 57.6% knew about the need for CAR-T patients. Additionally, only 15.2% knew where to find information on selecting irradiated blood products at AMC. The analysis highlighted a significant knowledge gap in transfusing irradiated blood products for hematological and oncological malignancies. In response, a user-friendly educational resource was created and displayed in residents' conference rooms during inpatient rotations, with plans for intermittent educational sessions over the next months. A comprehensive educational initiative addressed this aspect of patient care within the inpatient service, distributing detailed materials and discussions with the internal medicine residents at AMC. The focus was on emphasizing the critical requirement for irradiated blood products in specific clinical scenarios, particularly when managing patients with hematological malignancies and other conditions where irradiated blood is medically indicated. Results: A follow-up survey, conducted four months after distributing educational material on medicine floors, included responses from 27 internal medicine residents. Notably, 100% and 88.9% were knowledgeable about the necessity of irradiated blood products in hematological malignancies and bone marrow transplant recipients, respectively. Additionally, 24 out of 27 residents were aware that irradiated products are unnecessary for solid tumor malignancies in adult patients. All residents knew where to find information on blood product selection at AMC, and 92.6% found the education material helpful. Conclusions: Improved knowledge among residents underscores our commitment to patient care. We aim to extend education on irradiated blood product necessity beyond our residency program. Our long-term vision is to broaden this critical knowledge across the healthcare community at AMC.

Implementation and Outcomes of Outdoor Science Education in an Urban Setting on Primary and Intermediate Level Students with Emotional and Behavioral Disorders

The term nature deficit disorder describes the “human costs of alienation from nature” (Louv, 2019). While not meant to be a medical diagnosis, Louv argues that the condition has, “profound implications, not only for the health of future generations but for the health of the earth itself” (Louv, 2008). Children most at risk are those who live or go to school in an urban setting, as well as students diagnosed with Emotional and Behavioral Disorders (EBD). Students diagnosed with EBD are often kept indoors as their teachers and caretakers are frequently trained in the indoor use only of behavior management techniques (Riden et al., 2022). This means that during professional development training, any that pertain to behavior management techniques, procedure, or protocol are routinely taught inside of a classroom, conference room, or recently home office, using an indoor scenario (classroom, auditorium, cafeteria, etc.) as an example of when and how to use these behavior management tools. Outdoor professional development, equipping students with natural tools that can help improve not only their physical but also their mental health, as well as connecting students with nature in a way that teaches them to advocate for the health of the earth, thus becoming citizen stewards are all themes that are part of the massive, currently dysfunctional system that is outdoor education in schools. This study shows that when students are encouraged to interact with nature on their own terms on-task behaviors and motivation increase. Students also retained lesson information and asked follow-up questions after the lesson when taught outside using hands-on activities.

Flexible Self-Powered Low-Decibel Voice Recognition Mask.

In environments where silent communication is essential, such as libraries and conference rooms, the need for a discreet means of interaction is paramount. Here, we present a single-electrode, contact-separated triboelectric nanogenerator (CS-TENG) characterized by robust high-frequency sensing capabilities and long-term stability. Integrating this TENG onto the inner surface of a mask allows for the capture of conversational speech signals through airflow vibrations, generating a comprehensive dataset. Employing advanced signal processing techniques, including short-time Fourier transform (STFT), Mel-frequency cepstral coefficients (MFCC), and deep learning neural networks, facilitates the accurate identification of speaker content and verification of their identity. The accuracy rates for each category of vocabulary and identity recognition exceed 92% and 90%, respectively. This system represents a pivotal advancement in facilitating secure and efficient unobtrusive communication in quiet settings, with promising implications for smart home applications, virtual assistant technology, and potential deployment in security and confidentiality-sensitive contexts.

Development of Virtual Tours for Understanding the Built Environment of an Educational Building

Though we spend a significant amount of time in indoor and built environments as general occupants of residential or commercial spaces, we do not necessarily know how the heating, cooling, and ventilation services work in our occupied spaces. As the mechanical systems of buildings become more complex for energy saving and better indoor air quality, it is beneficial for occupants to learn more their built environment so that they can cooperate effectively for the building’s performance. In this context, the purpose of this research is to develop and evaluate how virtual reality (VR) technology can support occupants in understanding their built environment. An educational building on campus was selected for the development as it provides familiar spaces for potential participants in this research. This research was carried out in two stages. In Stage One, we, as researchers in mechanical engineering, explored the workflow for VR development and developed VR tours for four spaces: a classroom, an auditorium, a conference room, and a mechanical room. In Stage Two, we conducted a survey study to examine the VR experience from the perspective of users. In this survey study, we recruited 34 participants from engineering students/graduates, industry participants, and a sustainability group. The participants generally indicated a positive experience with the VR tours, although the quiz scores on the VR content were weak. From our reflection, we consider that positive and effective VR experiences for the education of the built environment require collaboration from three domains: (1) mechanical systems of buildings, (2) VR technology, and (3) pedagogy.

Exploiting channel state information of WiFi signal for human activity detection: an experimental study

Ubiquitous computing aims to seamlessly integrate computing into our daily lives, and requires reliable information on human activities and state for various applications. In this paper, we propose a device-free human activity recognition system that leverages the rich information behind WiFi signals to detect human activities in indoor environments, including walking, sitting, and standing. The key idea of our system is to use the dynamic features of activities, which we carefully examine and analyze through the characteristics of channel state information. We evaluate the impact of location changes on WiFi signal distribution for different activities and design an activity detection system that employs signal processing techniques to extract discriminative features from wireless signals in the frequency and temporal domains. We implement our system on a single off-the-shelf WiFi device connecting to a commercial wireless access point and evaluate it in laboratory and conference room environments. Our experiments demonstrate the feasibility of using WiFi signals for device-free human activity recognition, which could provide a practical and non-intrusive solution for indoor monitoring and ubiquitous computing applications.

Implementation of Energy Efficiency and Visual Comfort in Malang’s Foreign Exchange Office Lighting

The Victory International Futures office is running on foreign exchange. It is located in East Java, Indonesia, in Malang. The furniture in this office has an HPL finish, which is typically dark and has a brown cotton color. The light source’s reflections will be lessened as a result. The southeast-facing Victory International Futures building has good lighting. However, the lighting may be improved due to the limited artificial lighting offered in some areas and the absence of windows, which prevents daytime sunshine from reaching its full potential. Using windows where none are present results in an improper exchange of air coming in and going out. This study intends to ascertain the effects on workers caused by the influence of office air circulation and light intensity. This study’s technique, a case study, requires that we visit the office right away. Data gathering methods included surveys, interviews, and using the Light Metre program to gauge light intensity. According to the test results, the typical room has more light than it needs at night. Through smart lighting, this research proposes designs to enhance the quality of conference room interiors, particularly lighting design. A standard light distribution of 73,9 lux is achieved by simulating one type of lamp already present in the space using the Light Metre application.
