Few-Shot Remote Sensing Novel View Synthesis with Geometry Constraint NeRF

Novel View Synthesis (NVS) is an important task for 3D interpretation in remote sensing scenes, which also benefits vicinagearth security by enhancing situational awareness capabilities. Recently, NVS methods based on Neural Radiance Fields (NeRFs) have attracted increasing attention for self-supervised training and highly photo-realistic synthesis results. However, it is still challenging to synthesize novel view images in remote sensing scenes, given the complexity of land covers and the sparsity of input multi-view images. In this paper, we propose a novel NVS method named FReSNeRF, which combines Image-Based Rendering (IBR) and NeRF to achieve high-quality results in remote sensing scenes with sparse input. We effectively solve the degradation problem by adopting the sampling space annealing method. Additionally, we introduce depth smoothness based on the segmentation mask to constrain the scene geometry. Experiments on multiple scenes show the superiority of our proposed FReSNeRF over other methods.

Methodology for Developing an IoT-based Parking Space Counter System using XNO

The Blockchain-IoT integration is treated as the future technological value by many adopters despite the cost or complexity involved. But, there are technological advancements brought in by communities that make solutions affordable and simple to the fact that they can be used in applications such as parking space counters. This research portrays use of XNO which is a digital currency in an alternative way to keep track of available parking spaces via IoT nodes installed at entry and exit points of parking lots. The available parking spaces data using this approach can be displayed on LED boards at the entry point of the parking lots and on a website for remote status view. An add-on for this research is the issue of entry tickets with timestamp and unique ID by using the block data during asset transfer. This research can be further enhanced for collection of parking fees by the help of IoT nodes at the exit points of the parking lots.

Rural and remote psychologists’ views on provisional psychologist supervision

ABSTRACT Objective South Australia’s rural and remote psychology workforce is experiencing shortages. However, in seeking to place provisional psychologists in rural settings, universities have found it difficult to recruit supervising psychologists. This study seeks to understand what rural and remote psychologists view as the barriers and facilitators of supervising provisional psychologists. Method A qualitative research methodology was used. Ten rural or remote psychologists participated in semi-structured interviews. Data were analysed using reflexive thematic analysis. Results Barriers and Facilitators were explained by participants, including three sub-themes to Facilitators not previously reported in the literature: Benefits, Ownership, and Motivation. All participants expressed altruistic motivations for supervision however factors such as the Medicare rebate rates, feelings of division within the profession of psychology, and confusion about required qualifications to supervise acted as deterrents to offering supervision. Differences were evident between supervision in public and private practice contexts. Conclusions The findings from this study warrant further exploration and action from the profession and government. Proposed solutions to the barriers identified include government funding for supervision, equalising the Medicare rebate items, and better promoting the benefits of supervising. This research offers novel insight into the views of rural psychologists on supervision and professional commitment more broadly.

Remote infrared view of JET divertor compatible with D-T operations

A remote viewing system located outside the biological shield wall to image the divertor region in JET is presented here. This paper focuses on the optical and mechanical designs of the installation of a line of sight which is capable of imaging the divertor over an optical distance of approximately 31 m. In addition, it includes the experience obtained during operations and it demonstrates its successful performance. This line of sight was the second viewing system used during the D-T campaign and it follows from the paper dedicated to the remote wide angle view line of sight which is also compatible with D-T operations and includes common elements to the construction of the two lines of sight. The main novel feature is the design in house of two glass reinforced plastic kinematic mounts standing vertically to each accommodate a mirror of 500 mm in diameter.

Neural Radiance Fields for High-Resolution Remote Sensing Novel View Synthesis

Remote sensing images play a crucial role in remote sensing target detection and 3D remote sensing modeling, and the enhancement of resolution holds significant application implications. The task of remote sensing target detection requires a substantial amount of high-resolution remote sensing images, while 3D reconstruction tasks generate denser models from diverse view perspectives. However, high-resolution remote sensing images are often limited due to their high acquisition costs, a scarcity of acquisition views, and restricted view perspective variations, which pose challenges for remote sensing tasks. In this paper, we propose an advanced method for a high-resolution remote sensing novel view synthesis by integrating attention mechanisms with neural radiance fields to address the scarcity of high-resolution remote sensing images. To enhance the relationships between sampled points and rays and to improve the 3D implicit model representation capability of the network, we introduce a point attention module and batch attention module into the proposed framework. Additionally, a frequency-weighted position encoding strategy is proposed to determine the significance of each frequency for position encoding. The proposed method is evaluated on the LEVIR-NVS dataset and demonstrates superior performance in quality assessment metrics and visual effects compared to baseline NeRF (Neural Radiance Fields) and ImMPI (Implicit Multi-plane Images). Overall, this work presents a promising approach for a remote sensing novel view synthesis by leveraging attention mechanisms and frequency-weighted position encoding.

A Remote View into the Classroom: Analyzing Teacher Use of Digitally Enhanced Educative Curriculum Materials in Support of Student Learning

ABSTRACT When integrated into online curriculum modules for students, educative curriculum materials (ECMs) can enhance teachers’ enactment of these modules. This study investigated (1) the use of digitally enhanced ECMs built into an online plate tectonics curriculum module by teachers with different backgrounds and teaching experience, (2) the relationship between teachers’ use of ECMs and student learning gains, and (3) teacher reflections on the value of the ECMs they used. We studied 26 teachers who taught middle and high school students (n = 1,098) by analyzing teacher log files automatically generated by the ECMs, teacher reflections collected with post-implementation surveys and interviews, student log files, and student learning gains from pretest to posttest. Results indicate that (1) there were large variations in the amounts and types of ECM features teachers accessed, (2) middle school teachers accessed significantly more ECM features than high school teachers p < .01, (3) students of teachers who used ECMs during class time made significantly higher learning gains than students of teachers who used them only before and/or between class time, p < .05, and (4) teachers most valued ECM features on student assessment. An overall non-significant, but positive, correlation between the total teacher interactions with ECMs and student learning gains was observed, r = 0.20, p = .32.

Remote wide angle view broad wavelength viewing system compatible with D-T operations in JET

Imaging diagnostics in Joint European Torus have become essential in the study of plasma wall interactions and the protection of the plasma facing components. During deuterium operations, the location of these diagnostics was at close proximity to the vessel. However, for the 50–50 deuterium-tritium operation, the neutron yield impact onto the electronics of these imaging diagnostics would have caused them to fail completely at these locations. Shielding these systems from neutrons is achieved by relocating a selected number of these imaging systems to outside the Torus Hall (i.e. to the other side of the biological shield wall). The relocation encompasses the construction of two new lines of sight crossing through the biological shield wall and each of them using an optical relay which extends to separate ports in the machine. This article starts with a brief description of two new viewing systems. However, it focuses on the optical modelling and engineering design of one of them which is a multiple camera system producing a wide angle view (WAV) of the inside of the vessel. This WAV system has been used successfully during the recent D-T campaign. It operates in a broadband wavelength range extending from the visible to the middle infrared. It also incorporates a novel in-house horizontal kinematic mirror mount made from glass reinforced plastic as part of the optical relay. The operational stability of the WAV system has also been assessed and some post design improvements implemented.

A Remote Sensing View of the 2020 Extreme Lake-Expansion Flood Event into the Peace–Athabasca Delta Floodplain—Implications for the Future SWOT Mission

The Peace–Athabasca Delta (PAD) in western Canada is one of the largest inland deltas in the world. Flooding caused by the expansion of lakes beyond normal shorelines occurred during the summer of 2020 and provided a unique opportunity to evaluate the capabilities of remote sensing platforms to map surface water expansion into vegetated landscape with complex surface connectivity. Firstly, multi-source remotely sensed data via satellites were used to create a temporal reconstruction of the event spanning May to September. Optical synthetic aperture radar (SAR) and altimeter data were used to reconstruct surface water area and elevation as seen from space. Lastly, temporal water surface area and level data obtained from the existing satellites and hydrometric stations were used as input data in the CNES Large-Scale SWOT Simulator, which provided an overview of the newly launched SWOT satellite ability to monitor such flood events. The results show a 25% smaller water surface area for optical instruments compared to SAR. Simulations show that SWOT would have greatly increased the spatio-temporal understanding of the flood dynamics with complete PAD coverage three to four times per month. Overall, seasonal vegetation growth was a major obstacle for water surface area retrieval, especially for optical sensors.

Validation and implementation of Aperio LV1 remote live view telepathology system for intraoperative frozen section diagnosis

IntroductionTelepathology (TP) allows for remote slide review with performance comparable to traditional light microscopy. Use of TP in the intraoperative setting allows for faster turnaround and greater user convenience by obviating the physical presence of the attending pathologist. We sought to perform a practical validation of an intraoperative TP system using the Leica Aperio LV1 scanner in tandem with Zoom teleconferencing software. MethodsA validation was performed in accordance with recommendations from CAP/ASCP, using a retrospectively identified sample of surgical pathology cases with a 1 year washout period. Only cases with frozen-final concordance were included. Validators underwent training in the operation of the instrument and conferencing interface, then reviewed the blinded slide set annotated with clinical information. Validator diagnoses were compared to original diagnoses for concordance. Results60 slides were chosen for inclusion. 8 validators completed the slide review, each requiring 2 h. The validation was completed in 2 weeks. Overall concordance was 96.4%. Intraobserver concordance was 97.3%. No major technical hurdles were encountered. ConclusionValidation of the intraoperative TP system was completed rapidly and with high concordance, comparable to traditional light microscopy. Institutional teleconferencing implementation driven by the COVID pandemic facilitated ease of adoption.

Effects of tracker location on the accuracy and precision of the Gazepoint GP3 HD for spectacle wearers.

Remote view eye-tracking systems are prone to errors when used on spectacle wearers due to reflections from the lenses and frame that result in inaccurate tracking. Traditionally, these trackers are situated below a computer monitor and the viewer's eye moments are recorded while they view the screen. Reflections may be influenced by the pantoscopic tilt of the spectacles, whereby the tilt angle causes incident light to be reflected to the camera. To overcome this problem, we propose mounting the tracker above the monitor to avoid these reflections and test the accuracy and precision of subjects with single vision spectacles, multifocals, and no correction, using both mounting positions. Experimental results showed that this alternate position had overall worse accuracy (4.06° ± 0.13) and precision (0.67° ± 0.05) compared to the standard configuration (2.15° ± 0.06 vs. 0.50° ± 0.03), with more invalid readings (5.91 vs. 19.19%) for single vision lens wearers. Multifocals performed better for the top-mounting position for the top portion of the monitor, suggesting higher-order aberrations from the bottom portion of the lens negatively impact data quality. Higher pantoscopic tilt angles displayed an improved accuracy for this alternate position (r(9) = - 0.69, p = 0.02), with superior accuracy for tilt angles greater than 14° compared to the standard configuration. This study quantifies the impact of spectacle wear on eye-tracking performance and suggests other alternate mounting positions may be viable in certain situations.

Connections, community and context: The importance of post-boarding school pathways and re-engagement for remote Aboriginal students

For many remote Aboriginal Australian students, periods of time during their secondary education are spent living away from home at a boarding school. While financial, political and community support is burgeoning for boarding models that provide scholarships, sports programs or accommodation for Aboriginal and Torres Strait Islander students, very little academic research or evidence exists that examines the experiences of students post-boarding. This paper forms part of a broader doctoral research study, but specifically focuses on how past students, families and communities from remote South Australia view the outcomes of boarding. Using a Grounded theory design, thematic analysis of 32 semi-structured interviews with past students, families and community members led to the identification of three main themes: connections (early exits), community (re-engaging in education), and context (employment in remote communities). Findings indicated that outcomes are not linear nor easily defined. Developing a theory of change was recommended as a future approach to help families, students and remote schools to clearly define goals and measures of success for each student, recognising a range of interpretations and conceptions of ‘success’, and adapting these goals as necessary.

Remote Sensing Novel View Synthesis With Implicit Multiplane Representations

Novel view synthesis of remote sensing scenes is of great significance for scene visualization, human-computer interaction, and various downstream applications. Despite the recent advances in computer graphics and photogrammetry technology, generating novel views is still challenging particularly for remote sensing images due to its high complexity, view sparsity and limited view-perspective variations. In this paper, we propose a novel remote sensing view synthesis method by leveraging the recent advances in implicit neural representations. Considering the overhead and far depth imaging of remote sensing images, we represent the 3D space by combining implicit multiplane images (MPI) representation and deep neural networks. The 3D scene is reconstructed under a self-supervised optimization paradigm through a differentiable multiplane renderer with multi-view input constraints. Images from any novel views thus can be freely rendered on the basis of the reconstructed model. As a by-product, the depth maps corresponding to the given viewpoint can be generated along with the rendering output. We refer to our method as Implicit Multiplane Images (ImMPI). To further improve the view synthesis under sparse-view inputs, we explore the learning-based initialization of remote sensing 3D scenes and proposed a neural network based Prior extractor to accelerate the optimization process. In addition, we propose a new dataset for remote sensing novel view synthesis with multi-view real-world google earth images. Extensive experiments demonstrate the superiority of the ImMPI over previous state-of-the-art methods in terms of reconstruction accuracy, visual fidelity, and time efficiency. Ablation experiments also suggest the effectiveness of our methodology design. Our dataset and code can be found at https://github.com/wyc-Chang/ImMPI

Remote-only monitoring for patients with cardiac implantable electronic devices: a before-and-after pilot study.

Background:Outcomes for patients with cardiac implantable electronic devices are better when follow-up incorporates remote monitoring technology in addition to in-clinic visits. For patients with implantable devices, we sought to determine the feasibility, safety and associated health care utilization of remote-only follow-up, along with its effects on patients’ quality of life and costs.Methods:This multicentre before-and-after pilot study involved patients with new or existing pacemakers or implantable cardioverter defibrillators. The “before” phase of the study spanned the period October 2015 to February 2017; the “after” phase spanned the period October 2016 to February 2018. The exposure was remote-only follow-up in combination with Remote View, a service that facilitates access to device data, allowing device settings to be viewed remotely to facilitate remote programming. Outcomes at 12 months were feasibility (adherence to remote monitoring), safety (rate of adverse events) and health care utilization (remote and in-clinic appointments). We also assessed quality of life, using 3 validated scales, and costs, taking into account both health care system and patient costs.Results:A total of 176 patients were enrolled. Adherence (defined as at least 1 successful remote transmission during follow-up) was 87% over a mean follow-up of 11.7 (standard deviation 2.2) months. There was a reduction in in-clinic visits at specialized sites among patients with both implantable defibrillators (26 v. 5, p < 0.001, n = 48) and pacemakers (42 v. 10, p < 0.001, n = 51). There was no significant change in visits to community sites for patients with defibrillators (13 v. 17, p = 0.3, n = 48). The composite rate of death, stroke, cardiovascular hospitalization and device-related hospitalization was 7% (n = 164). No adverse events were linked to the intervention. There was no change in quality-of-life scales between baseline and 12 months. Health care costs were reduced by 31% for patients with defibrillators and by 44% for those with pacemakers.Interpretation:This pilot study showed the feasibility of remote-only follow-up, with no increase in adverse clinical outcomes and no effect on quality of life, but with reductions in costs and health care utilization. These results support progression to a larger-scale study of whether superior effectiveness and reduced cost can be achieved, with preservation of safety, through use of remote-only follow-up.

Media Ecologies of the ‘Extractive View’

Abstract Extraction displaces materials and reorganises habitats by accumulating resources – a process that renders populations and natural reserves as extractable data to be mobilised in systems of metabolic exchange. In contemporary practice, collecting, sorting, and processing this data require a complex interoperability between sensors, computing platforms, and databases before they are made into earth observation images. Following the scholarly research on the instrumentality of aerial survey in histories of extractive colonialism, this essay sheds light on the extractive capacity of remote sensing technologies in contemporary mining industries. Engaging with the media infrastructures of resource exploration, the inquiry revisits Heidi Scott’s theory of ‘colonialism’s vertical third dimension’ and extends it from the physical to the sensory, numerical, and temporal domains of extractivism. After Sean Cubitt’s classification of mediated earth observation, the three geomedia, the discussion is organised in three parts: electromagnetic sensing, numerical translations, and financial futures. A media-archaeological analysis of earth observation systems brings forth the extractive codes of the remote view by revealing its selective, vectoral, and speculative capacities in tapping the earth and ordering its resources into materials of exchange. Keywords: extractive view, mining industries, remote sensing, geomedia, digital image, aerial surveillance, urbanisation, datafication

Remote view of education, teacher, student and school concepts in teacher training

In this study, the experiences, feelings and thoughts of the instructors working in the teacher training program about distance education were examined. Therefore, the research is a phenomenological study. A focus group discussion was held. The study group of the research consisted of 5 volunteer lecturers. Faculty members criticize the university's preferred learning management system that allows limited communication. He argues that this provides opportunities for education rather than education. According to the instructors, the students perceived the individual learning preference, which is the most basic advantage of distance education, as irresponsibility rather than freedom. In summary, according to the instructors, interaction and role models are needed in the learning environment. In addition, technical and psychological preparation is important for a successful distance education.

코로나시대 물류 서비스 관련 분야 직장인의 언택트 업무 사례 연구

The purpose of this study was to research the status of logistic service-related workers about untact works by case study in the Era of COVID-19. An experimental design was used by case analysis of interviews with ten office workers from May to June 2020. The results of this research were divided into three categories: work environment, work management and work effect. First, teleworking has a significantly positive influence on business efficiency about work environment. ZOOM, One drive, Skype, Chatbot, Microsoft Teams and Remote view are used as collaborative applications. Second, work instructions in documents are needed such as e-mail and messenger using information and communication technology about work management. Third, the strong points of teleworking are both high work efficiency and job satisfaction about work effect. The weak points of teleworking are both very low-technology and misunderstanding about work effect. The result offer some insights into the case study of logistic service-related workers about untact works. Based on the results, the implications and the limitations of this study were discussed.

Research on Remote GPS Common-View Precise Time Transfer Based on Different Ionosphere Disturbances.

Propagation path delays are a major error for the remote precise time transfer of common view; these path delays contain the ionosphere and troposphere impact, while the contributions of the ionosphere and the troposphere from common-view satellites to receivers on the ground tend to become uncorrelated when the distance between these receivers increases. In order to select the appropriate ionospheric correction method for common view under different distances between receivers, a detailed test using multi-source data under different ionosphere disturbances are carried out in this paper. Here, we choose three different ionosphere disturbance methods and analyze the advantages and disadvantages of these methods for common-view time transfer and time comparison. At last, we put forward a suitable ionospheric correction method for different distances common view. The RMS shows that the method proposed for 3000 km remote common view can achieve 2.5 ns.

Feasibility and acceptability of internet-delivered parent-child interaction therapy for rural Australian families: a qualitative investigation.

Parent-child interaction therapy (PCIT) is an evidence-based parent management training program for the treatment of childhood disruptive behaviour disorders (DBDs). In Australia, however, due to a lack of services in regional, rural and remote areas, the program is not accessible to all families who might benefit. Preliminary evidence demonstrates that telehealth technologies can be leveraged to deliver PCIT via internet (I-PCIT) to urban families. It is not known, however, to what extent I-PCIT is acceptable and effective for regional and remote families, who are traditionally underserved and face a range of stressors unique to living outside major cities. The present study represents the first qualitative investigation into the experience of I-PCIT for rural or regional Australian families. Qualitative interviews were conducted with 10 parents who were living in regional, rural and remote areas of New South Wales (NSW), Australia, and who were referred to an I-PCIT program for treatment of DBD in a child aged 2-4 years. Thematic analysis yielded two pre-treatment themes: motivation for seeking treatment and barriers to previous service access. Three overarching themes were identified in post-treatment interviews: positive outcomes, valuable program components and challenges and acceptability of internet delivery. Results demonstrate that consumers from regional, rural and remote NSW view I-PCIT as an acceptable and effective treatment of childhood DBD, bolstering preliminary evidence about the utility of internet technologies to deliver the high-quality results of PCIT. While internet connection issues were a hindrance to treatment for some participants, all parents reported meaningful positive outcomes for both child and parents. The study highlights that I-PCIT effectively expands the reach of mental health services to Australian communities that previously could not access clinic-based parenting services.

BISMILLAH, SAYA MENIKAH Studi Kasus Pembentukan Keluarga pada Pasangan Mahasiswa

Every human being has a requirement to overcome loneliness. In accordance with the theory of early adult development, one of the ways to against it is to build a family. But, couples who did it while just a college student has a complex challenge, especially if deciding taaruf because of religious rules that prohibit relationships before marriage. The aim of this research is to understand the psychological dynamics of college students in building a family through the taaruf process.This research uses the qualitative method with a case study approach. Researchers involve two subjects of college students who have been married. Data collection was done by interview, observation, and focus group discussion. Couples who build a family by taaruf process, through four stages, there are understanding relations concept, introductions, taaruf, and marriage. They made the interaction in line with Islamic rules that do not allow courtship. The introduction made only a remote view. During the process of taaruf, there is no direct communication to avoid romantic shade. The wedding process becomes an important epiphany in life. Marriage is perceived as a social support that positively affects academic responsibility. Taaruf may be an alternative choice to avoid relationship which is not appropriate with religious rules. College students who decide to build a family, especially through the taaruf process, need to ensure their readiness in academic responsibility.

PILOT STUDY TO ASSESS THE FEASIBILITY OF REMOTE ONLY FOLLOW-UP FOR CARDIAC IMPLANTABLE ELECTRONIC DEVICES

Remote monitoring (RM) coupled with in-clinic follow-up is cost-effective and superior to solely in-clinic follow-up for both pacemakers (PMs) and implantable defibrillators (ICDs). Remote View technology permits specialised sites to program ICDs of patients off site. We sought to determine the feasibility of remote only follow-up, eliminating scheduled clinical visits and travel to specialised sites.
