With the advancement of wireless communication technology, the number of wireless network terminals has exploded, and various new business scenarios have emerged. The 6G mobile communication technology not only surpasses 5G standards in terms of transmission rate, delay, power and other performances, but also extends the communication range to multiple fields such as air, ground, ocean, etc., which greatly promotes Unmanned Aerial Vehicle (UAV) communication technology research and development. Compared to terrestrial networks, UAV communication has advantages such as high flexibility and easy deployment. However, there are still many problems and challenges in practical applications. In this paper, we will first introduce the functions and application scenarios of UAV communication, then discuss the current challenges and related technical research, and finally look forward to the future development prospects.

This study aims to shed light on the conceptual implications of emerging media or emergent media from a transdisciplinary perspective. Drawing on the philosophical thoughts of complex dynamic systems and emergentism, this study reviews the literature across various disciplines bearing on emerging media and illustrates the value of invoking the concept to understand the fast-evolving communication technologies. Emerging media is defined as complex dynamic systems that are constituted through and in communication practices, suggestive of both materiality and sociality, and characterized by emergent processes. By emphasizing a conceptualization of media as dynamic, emergent, relational, and situated systems, this study calls for empirical studies of emerging media employing a transdisciplinary approach.

This paper explores how a future – as something that can only be imagined but can inspire entrepreneurial action – can attract economic capital. We integrate Dor's (2015) model of language as a communication technology for the instruction of imagination with Bourdieu's theory of practice to account for how an entrepreneur's words can hold sway over an investor by virtue of meaning something significant. We introduce opportunity capital as the symbolic significance of the entrepreneur's future-venture story and the exchange counterparty to the investor's economic capital. Our portrayal of the future as a symbolic phenomenon inducing action by others offers foundational insights to research on the early stages of venturing and the acquisition of resources by entrepreneurs.

This article considers opportunities for election knowledge communication and voter education in technical communication pedagogies. Drawing on three projects – the “Advocacy White Paper,” “Technical Instructions & Infographic Design,” and “Non-Profit Social Media Content Strategy” projects – the article considers how technical communication instructors can design pedagogies that engage civic exigencies related to democracy. The article argues that technical communicators should make election knowledge communication and voter education priorities in their pedagogies, practices, and discipline. [ABSTRACT FROM AUTHOR]

Emerging reconfigurable metasurfaces offer various possibilities for programmatically manipulating electromagnetic waves across spatial, spectral, and temporal domains, showcasing great potential for enhancing terahertz applications. However, they are hindered by limited tunability, particularly evident in relatively small phase tuning over 270°, due to the design constraints with time‐intensive forward design methodologies. Here, a multi‐bit programmable metasurface is demonstrated capable of terahertz beam steering facilitated by a developed physics‐informed inverse design (PIID) approach. Through integrating a modified coupled mode theory (MCMT) into residual neural networks, the PIID algorithm not only significantly increases the design accuracy compared to conventional neural networks but also elucidates the intricate physical relations between the geometry and the modes. Without decreasing the reflection intensity, the method achieves the enhanced phase tuning as large as 300°. Additionally, the inverse‐designed programmable beam steering metasurface is experimentally validated, which is adaptable across 1‐bit, 2‐bit, and tri‐state coding schemes, yielding a deflection angle up to 68° and broadened steering coverage. The demonstration provides a promising pathway for rapidly exploring advanced metasurface devices, with potentially great impact on communication and imaging technologies. [ABSTRACT FROM AUTHOR]

The application of wireless communication principles and scenarios in the field of intelligent logistics has triggered innovation and patent output in the wireless communication domain. This study analyses the patent network of wireless communication collaborative innovation in the logistics field, covering the period from 2000 to 2020, and identifies the main innovation entities and changes in the network structure. The number of patent holders increased from 14 individuals in 2000–2006 to 525 individuals in 2014–2020, with universities taking the lead followed by enterprises and research institutions. The node degree grew 150 times, from 6 to 1500. However, the network density decreased from 0.0659 to 0.0109, indicating that despite the increase in the number of innovation entities, the collaboration among them is not close. The overall network centrality is relatively low, but some central nodes emerged in the later stage of the study, including universities, research institutions, and state-owned enterprises. The study suggests the need to strengthen collaborative innovation activities and knowledge sharing as the network continues to expand. In terms of the distribution of underlying technologies, "wireless communication in logistics" primarily focuses on technologies such as NEW RADIO (NR), NEW CORE (NC), and LTE.

Time-sensitive networking (TSN) is a kind of network communication technology applied in fields such as industrial internet and intelligent transportation, capable of meeting the application requirements for precise time synchronization and low-latency deterministic forwarding. In TSN, cyclic queuing and forwarding (CQF) is a traffic shaping mechanism that has been extensively discussed in the recent literature, which allows the delay of time-triggered (TT) flow to be definite and easily calculable. In this paper, two algorithms are designed to tackle the start time planning issue with the CQF mechanism, namely the flow–path–offset joint scheduling (FPOJS) algorithm and congestion-aware scheduling algorithm, to improve the scheduling success ratio of TT flows. The FPOJS algorithm, which adopts a novel scheduling object—a combination of flow, path, and offset—implements scheduling in descending order of a well-designed priority that considers the resource capacity and resource requirements of ports. The congestion-aware scheduling algorithm identifies and optimizes congested ports during scheduling and substantially improves the scheduling success ratio by dynamically configuring port resources. The experimental results demonstrate that the FPOJS algorithm achieves a 39% improvement in the scheduling success ratio over the naive algorithm, 13% over the Tabu-ITP algorithm, and 10% over the MSS algorithm. Moreover, the algorithm exhibits a higher scheduling success ratio under large-scale TSN. [ABSTRACT FROM AUTHOR]

Switching-mode power amplifiers have provided unprecedented opportunities for modern wireless communication technology. However, its single-ended structure suffers from significant harmonic interferences on signal transmission; in some cases, higher return loss caused by the impedance mismatch may damage or even destroy the device directly. Here it shows, analytically and experimentally, a broadband push–pull parallel-circuit (PC) Class-E power amplifier (PA) which can present high efficiency and flatness gain over a wide frequency range. Based on the broadband capability of the proposed structure, a highly-efficient push–pull PC Class-E PA combining single reactance compensation technique and Chebyshev low-pass impedance matching network (MN) is designed and fabricated. Experimental results demonstrated that a drain efficiency of 93.71–94.62% operating from 7.0 to 9.4 MHz, as well as output power (Pout) of 42.1–44.57 dBm and power gain of 14.1–16.57 dB are obtained. The measurement results show good agreements with the simulation results, which may be a potential candidate for electronic article surveillance (EAS) applications operating in the high-frequency band.

With the development of communication technology that makes online transactions easier, there is also an increased risk of disintermediation—sellers and buyers circumventing a platform to transact directly—in online two-sided marketplaces. Such disintermediation may lead to significant revenue loss for online platforms. However, it remains unclear how the characteristics of platforms affect their vulnerability to disintermediation. Using the blockade of Skype in mainland China as a natural experiment, this study examines how online communication technologies affect disintermediation and transaction outcomes in a large U.S. online freelance marketplace. The results show that restricting this alternative communication technology, which platforms struggle to monitor, reduces disintermediation by around 18%. This effect is potentially due to economic frictions in transactions, as the reduction in disintermediation is greater for high-transaction-cost jobs, such as time-sensitive jobs, communication-intensive jobs, and high-skilled jobs, as well as for cost-sensitive users, such as experienced users and personal users as opposed to enterprise users. With these results, platforms can reduce disintermediation risks when making investment and market entry decisions. This paper was accepted by D. J. Wu, information systems.

It is expected that 6G communication technology will achieve a peak data rate capability of 1 Tbit/s. One way of reaching this goal is to employ THz frequencies for carrying wireless signals. THz frequencies have large continuous bandwidths which allow for high data rate signals. In order to support the development of THz communications and accompanying technologies, a 6G THz Communications Testbed has been set-up at the National Physical Laboratory. In this paper, the best signal performance for a variety of different baud rates and modulation schemes is explored for both a direct connection between the waveform generator and measuring oscilloscope and for several different Over-The-Air (OTA) path lengths up to 4 m specular Non-Line-of-Sight. For the direct connection, signals of up to 210 Gbit/s were achieved and data rates of up to 150 Gbit/s were achieved for OTA transmission. [ABSTRACT FROM AUTHOR]

This article explores the usage and implications of the term “transnational” in research articles published in the prominent journal of Technical Communication from 2013 to 2023. Employing content analysis techniques, metasynthesis, and transrhetorical reading as self-reflective methods, this research reveals the diverse ways in which transnational is employed. The findings of this study suggest the adoption of transnational feminist frameworks to advance the goal of social justice in Technical and Professional Communication (TPC). [ABSTRACT FROM AUTHOR]

AbstractThis exploratory interpretative qualitative study aimed to investigate environmental factors influencing “in the moment” decisions about use of graphic symbols or spelling in face-to-face communicative interactions, by adolescents who use communication aids and are learning how to spell. The participants were six adolescents who used speech generating devices and their mothers. Data collection consisted of seven to eight communicative interactions between adolescents and their mothers and follow up interviews with the participants. Each dyad took part in three Zoom sessions. Researchers identified the communication mode shifts between graphic symbols and spelling during interactions and subsequently discussed with participants the reasons for these shifts. The interview data were analyzed using Charmaz’s constructivist grounded theory approach to coding. The analysis revealed three themes explaining environmental factors relevant to choosing spelling or graphic symbols in communicative interactions, which were: (a) features of the communication aid; (b) communication partner’s skills and their knowledge of the shared experience; and (c) opportunities to practice and use spelling. The findings provide insights into the importance of providing opportunities to practice and use spelling, communication partner’s skills and knowledge of shared experience and communication aid technology design which can help to facilitate spelling during communicative interactions.

Nonprofit organizations exist in a unique tension between survival and distinctiveness. Relying on interviews with staff members at hunger relief nonprofit organizations, we investigate how these nonprofits’ communication and rhetorical practices are being shaped by the tension between survival and distinctiveness, as well as the pressures/impulses of civic action, voluntarism, professionalism, and commercialism. Ultimately, we present a more nuanced understanding of how technical communication happens within nonprofits, specifically within the hunger relief sector, as well as offer takeaways for researchers, instructors, students, and community partners.

Numerous contemporary work teams encompass both virtuality, marked by geographically dispersed members relying on technology for communication, and fluidity, involving the rapid assembly of members with limited prior experience for immediate, time-sensitive tasks. Instances include global virtual teams, military command and control teams, and similar contexts in which rapidly assembled distributed teams are prevalent. However, research on fluid virtual teams remains scarce. In this article, we expound upon the concept of team fluidity, explain how fluid virtual contexts influence team dynamics, and explore the implications for effectively supporting fluid virtual teams.

The fast growth of communication technology has brought nations and their cultures closer together, and the demand for cross-language communication has risen tremendously. There is a different learning method to connect the source language to the target language in which unsupervised learning is a blessing for low-resource languages. The unsupervised machine translation is always problematic to those languages which are morphologically rich and low resources languages. Morphologically rich and low-resource language does not provide good results in machine translation if the translation is from morphologically less complex language to morphologically more complex languages. In this paper, we have improved the unsupervised neural machine translation by tackling the ambiguity problem and the quality of pseudo-parallel sentence pairs generated through back-translation for morphologically rich languages. The ambiguity problem is solved by taking the cross-lingual sense embedding at the source side instead of cross-lingual word embedding. By giving more weight to better pseudo-parallel sentence pairs in the back-translation step, the quality of pseudo-parallel sentences is increased. Different evaluation metrics have been used to check the robustness of the model and compared with different baseline models. The experiment is performed on different morphologically rich languages English-Hindi, English-Tamil, English-Telegu, and one low-resource endangered kangri language. [ABSTRACT FROM AUTHOR]

As immersive technology grows in popularity, universities are developing academic innovation labs (AIL) that often introduce students to virtual reality (VR) and other emerging cross reality applications. Although these labs help educate students on emerging technology, a more critical eye is needed to examine user experience (UX). This article reports on a qualitative, multimethod study that employed a talk-aloud UX protocol to gather data on VR users' experience at the University of Connecticut's OPIM Research Lab. To fully define and contrast this data, we juxtapose these individual narratives with rhetorical analysis of marketing discourse, as presented by VR platform HTC Vive, Google's VR application Tilt Brush, and the Research Lab's promotional material. Based on our findings, we assert that sociotechnical imaginaries as constructed by promotional material often reduce the complexities of immersion in user experience. Such marketing rhetoric creates "top-down" imaginaries that contrast with "bottom-up" imaginaries generated in user experience, reinforcing the complex and fluid definitions of immersion. The resulting study has practical implications for stakeholders across higher education, especially in the context of innovation labs, as well as for technical and professional communication educators and practitioners.

Since its release in late 2022, ChatGPT and subsequent generative artificial intelligence (GAI) tools have raised a wide variety of questions and concerns for the field of technical communication: How will these tools be incorporated into professional settings? How might we appropriately integrate these tools into our research and teaching? In this review, we examine research published in 2023–2024 addressing these questions (N = 28). Overall, we find preliminary evidence that GAI tools can positively impact student writing and assessment; they also have the potential to assist with some aspects of academic and medical research and writing. However, there are concerns about their reliability and the ethical conundrums raised when they are used inappropriately or when their outputs cannot be distinguished from humans. More research is needed for evidence-based teaching and research strategies as well as policies guiding ethical use. We offer suggestions for new research avenues and methods. [ABSTRACT FROM AUTHOR]

The six-step teaching mode has successfully improved students' independent learning ability, practical operation ability, teamwork spirit, and innovative thinking. The application of this mode in modern communication technology majors has a remarkable effect. This paper discusses the applicability of the six-step teaching mode in the contemporary communication technology specialty. It also discusses the implementation strategies of the six-step approach based on the online-offline hybrid mode, including creating an interactive problem situation to stimulate learning interest, utilizing multiple resources to support independent inquiry, building an online-offline collaboration platform to promote cooperation and communication, and designing innovative project tasks to guide innovative thinking. These strategies aim to effectively enhance the comprehensive ability of modern communication technology students and promote their overall development, which is of great significance for educational reform and practice.

In this letter, we consider a system based on LoRa (Long Range), which is one of the widely used IoT (Internet of Things) communication technologies. Recently, as the application areas of LoRa have expanded from low-speed to high-speed moving objects, an increase in error rates due to Doppler shift in high-speed environments has been reported. To address this issue, this letter proposes a new LoRa modulation scheme where information is conveyed by varying the frequency difference between two chirp signals. Additionally, an efficient demodulation algorithm is proposed to successfully demodulate information at the receiver even in the presence of residual carrier frequency offset. Numerical results demonstrate that the proposed LoRa modulation scheme can guarantee low error rates in mobile environments. [ABSTRACT FROM AUTHOR]

This study empirically examines the antecedents to users' intention to follow brands on the two most popular social media platforms, that is, Facebook and Instagram. Using the existing body of knowledge, a conceptual model was developed. Users appear to follow brands on Facebook and Instagram for different gratifications. The findings show that consumers who utilize social media platforms to follow brands perceive their usage as convenient and fruitful. Second, social circle pressure has a great impact on users in social media engagement with brands. Lastly, advertisers should design social media campaigns that provide value to consumers.

The social justice turn of the last two decades has spurred significant scholarship, but much remains to be done to gauge the impact of social justice scholarship on programmatic and curricular efforts. Programmatic and curricular development provides the primary, most important platform and “nurturing ground for promoting and enacting social justice” (p. 39), and that should engage our attention. This article is one such attempt, even if small, at contributing to this work by investigating justice, equity, diversity, and inclusion (JEDI) initiatives in introductory TPC classes across institutions in TPC programs nationwide. It reports the results of a survey of instructors of introductory TPC courses across US institutions as well as an analysis of syllabi used by those instructors. Noting a multiplicity of macro- and micro-level challenges to JEDI work, the authors call for increased and targeted curricular discussion of JEDI as well as focused support and training for instructors at the institutional and programmatic levels.

The Named Data Networking (NDN) is currently an important future network framework, and the mobility issue of producers within NDN is a primary challenge. However, in environments characterized by frequent producers mobility, traditional producer mobility support schemes still encounter issues such as excessive consumer delays and interest packet loss. With the development of The 6th generation communication technology (6G), integrating ground networks with satellites has emerged as a potential solution to address the aforementioned problems. In this paper, we propose an NDN producer mobility support scheme based on multi-satellite data depot, named MsDD. The proposed scheme proactively caches producer data into a data depot built on a low-earth orbit satellite constellation to minimize the impact of NDN producer mobility on network performance. We design data depot construction strategy, in-network caching strategy, and routing strategy based on forwarding hint to facilitate effective communication in satellite networks. Experimental results using ndnSIM demonstrate that compared with other existing schemes, MsDD can effectively shield the impact of producer mobility on consumer delay, delivery ratio, and signaling overhead, and MsDD has a clear advantage in terms of consumer delay and delivery ratio.

Objectives Design Methods Results Conclusions The objective of this study was to explore therapists' new‐found experiences of what works in successful cases of teletherapy.This was a qualitative study of therapists' experiences, making their implicit knowledge explicit and systematised.Twelve therapists were recruited via posts on social media and via the interviewers' professional networks. The therapists were interviewed at their office or via Zoom using a semi‐structured interview guide. The interviews were analysed using inductive, reflexive thematic analysis.The therapists described a number of interacting favourable factors, together contributing to successful remote treatments. Establishing a good therapeutic relationship and cooperation was a general success factor common to in‐person and remote treatments. Specific factors included well‐functioning communication technology, co‐creating a sense of co‐presence, safeguarding therapeutic boundaries adjusted to the remote setting, finding ways of compensating for the loss of several cues available in an in‐person setting and the patient being motivated for a remote therapeutic endeavour.In the successful cases, therapists in this study seem to have developed specific skills to counteract the inherent challenges and to benefit from the advantages specific to the remote setting. In the post‐pandemic era, when hybrid and remote therapeutic modalities become increasingly common, these specific skills and mechanisms have to be included in psychotherapy training programmes, supervision and continuing education.

The Terahertz (THz) band is seen as one of the potentially essential technologies to meet the data throughput requirements of terabits per second (Tbits) in future networks. Considering vehicular communication in particular, the current vehicular communication technologies cannot cope with the rapidly increasing data traffic. To deliver increased capacity and data rate with reduced latency, new technologies and methodologies are therefore required. It is recognized that one possible technology to meet these needs is THz technology. Since the change in distance between vehicles due to their speed affects THz communication, channel modeling was carried out for single-lane and multi-lane vehicular communication scenarios in this study. The system's performance was also examined. Performance metrics were determined as path loss, signal-to-noise ratio (SNR), capacity and bit error rate (BER). While performing these analyses, the absorption of THz waves is taken into account and the High-Resolution Transmission Molecular Absorption Database (HITRAN) was used to model it. As a result, the most appropriate circumstances for successful vehicular communication have been identified and studied. [ABSTRACT FROM AUTHOR]

Chatting is a technical means of communication used to connect individuals and ideas. There is a significant increase in chat applications and their users since last decade. However, the majority of these applications do not ensure end-to-end security for users. This paper presents the procedure to design an end-to-end chat application that guarantee secure communication. In this application, users can communicate with each other via server with secure memory storage. The proposed architecture focuses on end-to-end encryption of messages, such that the messages are only visible in the sender's and receiver's devices. There is no third-party interference in the communication. This approach reduces the network traffic and provides dedicated communication. [ABSTRACT FROM AUTHOR]

Communication technology helps protesters organize, but also allows the government to monitor and repress their actions. We study this trade‐off in a model where protesters want to show up at the same time and place, but also want to avoid government forces. If leaders of a movement can send messages observed only by other protesters, they can successfully coordinate on a variety of sites and force the government to spread resources thin, helping the success of the movement. If the government always observes the messages too, protesters can do no better than always going to a “focal site” knowing that the government will send all resources there as well, and thus experience higher levels of repression for the sake of coordinating tactics. Intermediate cases where messages are partially observed generate dynamics where new technologies and media that are relatively known to other protesters and not the government are used until the government can reliably infiltrate them and the protesters move on to a new medium. When some protesters are more informed than others, the model can explain protest tactics observed in recent prominent cases like having smaller “parallel” protests at the same time but different location of the main gathering.

Modern optical systems are important components of contemporary electronics and communication technologies, and the design of new systems has led to many innovative breakthroughs. This paper introduces a novel application based on deep reinforcement learning, D3QN, which is a combination of the Dueling Architecture and Double Q-Network methods, to design distributed Bragg reflectors (DBRs). Traditional design methods are based on time-consuming iterative simulations, whereas D3QN is designed to optimize the multilayer structure of DBRs. This approach enabled the reflectance performance and compactness of the DBRs to be improved. The reflectance of the DBRs designed using D3QN is 20.5% higher compared to designs derived from the transfer matrix method (TMM), and these DBRs are 61.2% smaller in terms of their size. These advancements suggest that deep reinforcement learning, specifically the D3QN methodology, is a promising new method for optical design and is more efficient than traditional techniques. Future research possibilities include expansion to 2D and 3D design structures, where increased design complexities could likely be addressed using D3QN or similar innovative solutions.

The joint utilization of the Fifth Generation Communications Technology (5G) and the Global Navigation Satellite System (GNSS) serves as a promising solution to address the challenges associated with insufficient visible satellites and lower observation quality in urban environments. 5G allows for the angle and distance measurements, augmenting the performance of Real-Time Kinematic (RTK) positioning. To quantify the improvement of 5G observations on RTK positioning, this paper proposes a float solution gain factor and the Ambiguity Dilution of Precision (ADOP) gain factor. Based on these gain factors, the theoretical analysis and simulation are performed. This study designs an extended Kalman filter for 5G-assisted BeiDou Navigation Satellite System (BDS) RTK positioning, employing both the Full Ambiguity Resolution (FAR) and Partial Ambiguity Resolution (PAR) modes. Our experiment verified the effectiveness of 5G-assisted BDS RTK positioning in mitigating outlier occurrences and improving the ambiguity fixing rate as well as the positioning accuracy. In the FAR and PAR modes, the Three-Dimensional (3D) spatial accuracy increased by 48% and 18.8%, respectively, and the results are consistent with theoretical analysis based on gain factors. The fixing rate of RTK increased from 11.11% to 13.93%, while it increased from 32.58% to 44.43% for the PAR mode. The assistance of 5G observations reduced the median error for the FAR mode from over 1.3m to 0.9 m, and the third quartile from 2.1m to 1.05 m. For the PAR mode, the median error decreased from 0.5m to 0.12 m, and the third and fourth quartiles decreased from 0.65m to 0.38 m. [ABSTRACT FROM AUTHOR]

This research talked - about the concept of atheism in the Qur’anic context, ways to respond to it, and mentioned its causes, through two aspects: First: a Qur’anic theory. Second: a contemporary scientific one bearing a late chronological character. The questions of this research are: What is the concept of atheism, and What is the difference between the past concept and the contemporary concept? What are the images of atheism in the Qur’an that explain its concept? What is the Quranic approach in responding to atheists? What are the causes of atheism, and what are the ways to disprove it in light of the Holy Qur’an? What is its danger and what are its effects? The research is based on the original transmitted method that depends on collecting correct information from its original sources, as well as the analytical method and the deductive method.

With the increasing demand for marine biosensing and water–air collaborative rescue in national production and life, establishing a robust cross-medium communication link has become one of the hotspots. Among them, microwave acoustic cross-medium uplink communication technology has been widely studied for its advantages of being able to be used all day and in all weather, there being no need for relay, and having high concealment. The principle is to extract the frequency of the acoustic water surface waves from the phase history of the radar echoes. However, wave interference can cause discontinuity of the phase history, resulting in difficulty in extracting the acoustic water surface waves and an increase in bit error rate (BER). This article analyses the reasons for the discontinuity of phase history and innovatively proposes a method for extracting acoustic water surface waves based on phase compensation. The discontinuity points of the phase history are compensated based on whether the range bin changes. Then, low-frequency water surface fluctuations and discontinuity points are filtered out through second-order differential joint outlier removal, which can effectively reduce the influence of phase history discontinuity on time–frequency analysis and communication decoding. The effectiveness of the proposed method was verified through simulations and experiments. The experimental results indicate that the BER of the proposed method is 25% of that of the Wavelet–Kalman Filtering method. The proposed method provides a new approach for microwave acoustic cross-medium uplink communication. [ABSTRACT FROM AUTHOR]

As digital technologies rapidly evolve, updating and enhancing models of digital literacy pedagogy in technical and professional communication (TPC) becomes more urgent. In this article, we use “digital life” to conceptualize the ever-changing ways of knowing and being in postinternet society. Using collaborative autoethnography, we investigate features of threshold concepts in TPC pedagogy that may support models of digital literacy that are resistant to tools-based definitions, foster student agency, and facilitate accessibility, equity, and justice.

With the development of wireless communication technology, Ultra-Wideband (UWB) has become an important solution for indoor positioning. In complex indoor environments, the influence of non-line-of-sight (NLOS) factors leads to increased positioning errors. To improve the positioning accuracy, fuzzy iterative self-organizing data analysis clustering algorithm (ISODATA) is introduced to process a large amount of UWB data to reduce the influence of NLOS factors, and to stabilize positioning error within 2 cm, enhances the accuracy of the positioning system. To further improve the running efficiency of the algorithm, FPGA is used to accelerate the key computational part of the algorithm, compared with running on the MATLAB platform, which improves the speed about 100 times, enhances the algorithm's computational speed dramatically.

This article focuses on analogue postcards as a communicative and artistic tool for potentially engaging nostalgically with the past, present, and future. It poses questions about the experience of time and place in a specific setting (the city of Montreal, Canada), as well as in a specific project that looks at cultural mediation in public spaces. During the summer of 2017, Comptoir public, an organization that works with artists and cultural mediators, launched the project "Postes du futur" (Mail from the Future). The organizers asked Montrealers to write a postcard to a recipient of the sender's choosing, so that it will be mailed in 2042 during the celebration of Montreal's 400th anniversary (i.e., 25 years later). One of our main findings is that most of these postcards will be sent to the current addresses of future recipients. Choosing one's home as one of the settings to write to and to write about finally made it possible to connect to the historical and medical meaning of nostalgia: the homesickness, the yearning for a place of one's own, for a space we now miss prospectively on in the future. Home, where people live their lives, is not yet "lost" or "left behind." But anticipating its loss and transfer to others becomes one of the primordial factors shaping instantaneous nostalgia and its expression—a future in which postcard senders are no longer present or even alive. The issue of the finiteness and the irreversibility of time is usually an indicator of past-oriented nostalgia. In our case, it is projected toward the future. The printed, analogue postcard becomes the writing space that leaves room for anticipated and anticipatory nostalgia and for imagining future communication technologies. [ABSTRACT FROM AUTHOR]

This study examines whether the use of Internet‐based communication technologies during election campaigns helps candidates to be elected to parliament and improves their perception of being able to win national elections. Using data from the 2013 Italian Candidate Survey, estimation results show that the use of a personal website and Twitter during the electoral race significantly improves candidates' perceptions of winning nationwide election and their likelihood of being elected to parliamentary office.

With the rapid development of wireless technology and Mobile communication technology worldwide, Mobile Learning represents a new learning trend in the field of higher education, and has gradually become the development trend and research hotspot of independent learning and lifelong learning. Based on modern wireless network mobile communication terminal technology, this paper proposes a Granott model-driven mobile learning system. Firstly, the Granott model is studied and analyzed, and the ubiquitous computing with physical integration and spontaneous interoperation is used to control the Android mobile terminal, which greatly improves the interactivity of M-Learning. Then JSON is selected to optimize the data transmission format in Ajax, and j Query is used to parse JSON data. Ajax + JSON + j Query can shield the complexity of DOM parsing XML files, greatly shorten the data transmission time and improve the efficiency of Granott model. Finally, the Fast kernel density estimation (Fast KDE) algorithm is introduced to compress the data transmitted by Ajax + JSON + j Query, so as to obtain a reasonable number of training samples. Through experiments and relevant data analysis, the proposed mobile learning system based on modern wireless network mobile communication terminal technology, optimized by JSON and Fast KDE algorithm, driven by Granott model, can efficiently complete the learning task, and improve the ubiquity, interactivity, timeliness of mobile learning.
