The behind-the-scenes story of how admen and sponsors helped shape broadcasting into a popular commercial entertainment medium. During the \"golden age\" of radio, from roughly the late 1920s until the late 1940s, advertising agencies were arguably the most important sources of radio entertainment. Most nationally broadcast programs on network radio were created, produced, written, and/or managed by advertising agencies: for example, J. Walter Thompson produced \"Kraft Music Hall\" for Kraft; Benton & Bowles oversaw \"Show Boat\" for Maxwell House Coffee; and Young & Rubicam managed \"Town Hall Tonight\" with comedian Fred Allen for Bristol-Myers. Yet this fact has disappeared from popular memory and receives little attention from media scholars and historians. By repositioning the advertising industry as a central agent in the development of broadcasting, author Cynthia B. Meyers challenges conventional views about the role of advertising in culture, the integration of media industries, and the role of commercialism in broadcasting history. Based largely on archival materials, A Word from Our Sponsor mines agency records from the J. Walter Thompson papers at Duke University, which include staff meeting transcriptions, memos, and account histories; agency records of BBDO, Benton & Bowles, Young & Rubicam, and N. W. Ayer; contemporaneous trade publications; and the voluminous correspondence between NBC and agency executives in the NBC Records at the Wisconsin Historical Society. Mediating between audiences' desire for entertainment and advertisers' desire for sales, admen combined \"showmanship\" with \"salesmanship\" to produce a uniquely American form of commercial culture. In recounting the history of this form, Meyers enriches and corrects our understanding not only of broadcasting history but also of advertising history, business history, and American cultural history from the 1920s to the 1940s.

Wireless energy harvesting enables the conversion of ambient energy into electrical power for small wireless electronic devices. This technology offers numerous advantages, including availability, ease of implementation, wireless functionality, and cost-effectiveness. Radio frequency energy harvesting (RFEH) is a specific type of wireless energy harvesting that enables wireless power transfer by utilizing RF signals. RFEH holds immense potential for extending the lifespan of wireless sensors and wearable electronics that require low-power operation. However, despite significant advancements in RFEH technology for self-sustainable wearable devices, numerous challenges persist. This literature review focuses on three key areas: materials, antenna design, and power management, to delve into the research challenges of RFEH comprehensively. By providing an up-to-date review of research findings on RFEH, this review aims to shed light on the critical challenges, potential opportunities, and existing limitations. Moreover, it emphasizes the importance of further research and development in RFEH to advance its state-of-the-art and offer a vision for future trends in this technology.

Efficient localisation plays a vital role in many modern applications of Unmanned Ground Vehicles (UGV) and Unmanned Aerial Vehicles (UAVs), which contributes to improved control, safety, power economy, etc. The ubiquitous 5G NR (New Radio) cellular network will provide new opportunities to enhance the localisation of UAVs and UGVs. In this paper, we review radio frequency (RF)-based approaches to localisation. We review the RF features that can be utilized for localisation and investigate the current methods suitable for Unmanned Vehicles under two general categories: range-based and fingerprinting. The existing state-of-the-art literature on RF-based localisation for both UAVs and UGVs is examined, and the envisioned 5G NR for localisation enhancement, and the future research direction are explored.

This article surveys the literature on miniature radio transmitters designed to track free-ranging wild animals using emitter-localization techniques. The articles covers the topics of power sources used in such transmitters, including miniature batteries and energy harvesting, techniques for generating the transmitted radio-frequency carrier, techniques for creating short radio pulses and more general on–off schedules, modulation in modern wildlife-tracking transmitters, construction, manufacturing, and tuning techniques, and recent trends in this area. The article also describes the recreation of the first successful wildlife-tracking transmitter, a nontrivial invention that had a profound impact on wildlife ecology, and explores its behavior.

In Tracking the Audience: The Ratings Industry From Analog to Digital, author Karen Buzzard examines the key economic, political, and competitive factors that have influenced ratings methods dominant in each of the markets for radio, TV, and the Internet, tracing the practice¹s history from its early beginnings up to its most recent advances. Beginning with the birth of the industry in 1929, Tracking the Audience traces the establishment of a standardized ratings &dquotecurrency&dquote as it evolved to meet the needs of the analog broadcast system, and explores the search for new gold standards necessitated by the devastating effects of the digital revolution. Buzzard examines key challenges to the established system by discussing the movement from traditional sampling methods to new, more transparent measurements. More than a history of the ratings industry itself, it also tracks the evolving business model for the broadcast industry. Tracking the Audience: The Ratings Industry From Analog to Digital shows how the development of conceptual tools designed to measure and package radio, TV, and Internet audiences is the result of a variety of historical factors. With a detailed examination of ratings providers, their methods, and their attempts to adjust to meet new demands a digital age, this volume explains how a standardized broadcast system of audience measurement ratings has evolved, and where it is going in the future.

Structural health monitoring (SHM) plays a critical role in ensuring the safety of large-scale structures during their operational lifespan, such as pipelines, railways and buildings. In the last few years, radio frequency identification (RFID) combined with sensors has attracted increasing interest in SHM for the advantages of being low cost, passive and maintenance-free. Numerous scientific papers have demonstrated the great potential of RFID sensing technology in SHM, e.g., RFID vibration and crack sensing systems. Although considerable progress has been made in RFID-based SHM, there are still numerous scientific challenges to be addressed, for example, multi-parameters detection and the low sampling rate of RFID sensing systems. This paper aims to promote the application of SHM based on RFID from laboratory testing or modelling to large-scale realistic structures. First, based on the analysis of the fundamentals of the RFID sensing system, various topologies that transform RFID into passive wireless sensors are analyzed with their working mechanism and novel applications in SHM. Then, the technical challenges and solutions are summarized based on the in-depth analysis. Lastly, future directions about printable flexible sensor tags and structural health prognostics are suggested. The detailed discussion will be instructive to promote the application of RFID in SHM.

Conventional thermal treatment in food processing relies on the transfer of heat by conduction and convection. One alternative to this conventional thermal treatment is radio-frequency (RF) heating in which electromagnetic energy is transferred directly to the heated product. The longer wavelengths of RF compared with microwaves are able to penetrate further into the food products resulting in more even heating. A review of RF heating for the food processing industry is presented here with an emphasis on scientific principles and the advantages and applications of RF. Applications of RF heating include blanching, thawing, drying, and processing of foods. RF heating represents considerable potential for additional research and the transfer of technology to the food processing industry. Computer simulation can be used to improve RF heating uniformity. Moreover, the heating uniformity in the rotated eggs is greater than in the static eggs. RF has also been used to blanch vegetables to increase ascorbic acid content to achieve the highest vitamin C levels. The use of the thawing technology has resulted in better quality of treated food. There has been increased interest in the RF-drying method due to the homogeneity of heating, greater penetration depth, and more stable control of the product temperature. RF-treated meat had improved quality and coagulation with acceptable taste and appearance. In addition, RF heating is used in pasteurization of yogurt and destruction of microorganisms in liquid and solid foods.
