This article is devoted to the discussion of the initial results of a research project devoted to the development of a magneto induction communication system, as well as the study of the main goal of the research at the moment: the search for profitable ways to build and transmit data. Based on the above goal, the physical meaning of the proposed method based on the electrohydraulic Yutkin effect was considered, which can be used to retransmit a signal under water between a network of antennas to increase the range of transmitted information. The creation of an experimental network of receiving and transmitting devices with a set of antennas will be the first step towards further research in the field of promising underwater wireless communications for use in the agro-industrial complex (AGP). The information presented in the text is recommended to a narrow circle of specialists, primarily in the field of information transmission, development of modern means of communication.

Abstract The simulation and investigation of a 32×10 Gb/s WDM all–optical bidirectional hybrid communication system for outdoor applications is presented in this article via multidisciplinary softwares. In order to track the system condition, a strain sensor based on fiber Bragg grating (FBG) is integrated in–line with the fiber optic link (FO–link). Then, a free space optical link (FSO–link) with 4–channel is simulated to act backup or rescue to the FO–link in the event of disaster or bombing. The FO–link is working well until the strain reach to 180 µε, after that the FO–link has degraded. Therefore, an optical switch is incorporated in between these systems (FO–link & FSO–link) to turn–on the FSO–link which act as a backup system to FO–link and maintains the continuity of the data transmission. According to the hybrid link results, there is an efficient enhancement in the Q–factor as compared with the FO–link even when there is heavy rain.

This article describes some suggestive findings on how young adults in Tokyo use mobile- and PC-based Internet resources outside of work or school. The primary interest is to explore leisure activities – and most notably, leisure outings – and how they are supported online. The findings presented here are initial results from an extensive research project designed to explore how Tokyo youth spend leisure time, and how they tend to coordinate, plan, and otherwise support leisure activities. The ultimate goal of the project is to help identify issues and opportunities for designing new online media to support leisure activities, especially leisure outings.

Grinnell College participated in ACRL’s first cohort of Assessment in Action (AiA), undertaking a mixed-methods action research project to assess the effectiveness of librarian-led research literacy sessions in improving students’ research skills. The quantitative data showed that the quality of students’ sources did not markedly improve following a research literacy session, while the qualitative data indicated that many students were able to state and describe important research concepts they learned. This article profiles the development of Grinnell’s AiA project and discusses how Grinnell’s librarians responded when the initial results led to more questions rather than to satisfactory answers.

In China, with the deepening of the reform of industrial structures, the improvement of technological innovation has become a key issue. This is not only related to whether the strategic development of Chinese science and technology can be achieved, but also whether the Chinese economy and high-quality human capital can develop sustainably. Based on the theoretical boundary of sustainable development—free transfer of information—we see that sticky wages are the embodiment of information dissemination. Under the dual effects of profit-seeking behavior and information barriers, the relationship between the sticky wages of technological innovation talents (TIT), as the most profitable labor force, and technological innovation efficiency (TIE) has become more complex, and so far we still have a limited understanding of it. We explore this issue in an empirical study by using a two-stage chain Data Envelopment Analysis (DEA) of TIE followed by modifying the wages of TIT; finally, we build a collaborative evolution model with spatial effects on a large dataset (from 2007 to 2016). The results show that the overall Chinese TIE is relatively low, and in the central and western regions the TIE has been seriously reversed; there are also divergences in the TIE at different stages in the regions we focus on. As the output of technological innovation, except for initial results (such as patents), the more important value is whether it has an ability to transform the initial results into production, and the core of it is whether it can match the market environment and technology transfer system (for example, market mechanism, transformation incentive mechanism, and institutional mechanism). So, considering these aspects, the central and west of China are obviously insufficient, while the east has obvious advantages; this can also explain the results of spatial diffusion, namely, in the eastern region it is higher than in other areas, but the gap between them is gradually narrowing; lastly, from the perspective of synergy, the wage stickiness of TIT in the central region is larger than that of the eastern and western regions, and the evolutionary relationship in the former is “extruding” while in the latter it is “cooperative.” Mainly due to the popularity of the eastern innovation network and the initial state of the west, the barriers of information transmission are relatively low, while the central part is undergoing economic transformation, so its extreme demand for TIT has pushed up the cost of information transmission.

This Major Research Project (MRP) aims to investigate the impact of the on-demand economy, millennials’ digital habits, and the emergence of super apps on the restaurant-finding process. Currently, restaurant-goers are presented with multiple specialty applications to complete different tasks when evaluating restaurants. The current process of deciding on a restaurant is both time-consuming and inefficient. This project aims to propose a solution to this problem in the form of an early-stage super app called Palate. Palate is a mobile application that aims to streamline the process of discovering restaurants from the moment a restaurant-goer begins their search to the moment they confirm a reservation. This paper will discuss design principles, theories of the on-demand economy, restaurant-goers digital habits, super apps and the rationale for designing a restaurant super app interface.

To solve the problem of image information transmission delay in the network multimedia teaching system, the compression and multicast solutions are put forward on the basis of usual screen blocking skill of data. According to the characteristics of the multimedia teaching system, the screen changes typically little at smaller intervals. It means that only a few screen blocks, which are changing, are needed to be transferred by screen blocking skill. At the same time, the network video data transmission volume is further curtailed through compression and multicast so that the multimedia information network transmission delay is decreased. The minimal buffer size for allocation is determined to ensure the smooth transmission of video data in the multimedia teaching system.

Over the years, the overdependence on Wireless Fidelity (Wi-Fi) for data transmission necessitated the need for an alternate and more reliable means of communication, hence, Light Fidelity (Li-Fi). It involves the use of Light Emitting Diode to transmit data by blinking (i.e. switching them on and off) at a speed not noticeable to the eye. This paper proposed the development of the Li-Fi system using off the shelf electronic components. This would make the system an indispensable means of communication in the nearest future. This data transmission system is different from those in existence because expensive components were not in the design, invariably reducing the overall cost of the implementation. Keywords: Light Fidelity (Li-Fi), Wireless Fidelity (Wi-Fi) Optical communication, Telecommunication

Abstract - In the 20th century this distance is still a constraint in efforts to measure and retrieve data. In an efficiency effort, a long distance measuring device is required. One method to measure from a distance is to use the Telemetry method. Telemetry is a method for measuring a variable in which monitoring is done remotely. The use of telemetry can be used to transmit data from the flowmeter sensor to be received by the receiver. This study discusses the effect of obstacles on transmitter work to send data to the receiver and test the accuracy of the flowmeter sensor. From this study it can be concluded that the effective distance of data transmission depends on the obstacle, the farthest distance is the moment without obstacles, then decreases when there is a hitch, and will decrease again when one receiver or transmitter is placed in a closed room. And for the accuracy of the sensor, the percentage of accuracy is low at the time of the slow water current, and vice versa high accuracy is obtained when the water current is fast. Based on the research we poured in this journal, water flow measurements using RF Arduino-based 433MHz Modules can measure the flow of water at a distance of up to 35meter with an average error of only 4.1%.

One of the challenges as well as opportunities for the success of wireless communication in the 21st century is the standardization that, in a simplified term, defines how specific technologies are used in a particular wireless communication system. Standardization goes beyond a technical decision made by engineers. This chapter first examines the history and the status of standardization in wireless communications in the world. Global cooperation and competition among different standards are then examined. Finally, the chapter analyzes ITU’s efforts on the 3G standardization that aim to bring harmony among the world’s wireless communication developers and providers.
