Most of the developed optical memory devices work within the ultraviolet and visible light illumination region. However, one of the most important illumination light sources is infrared (IR), which massively employed for data communication and information transfer, wireless networks, night visionary instrument, image sensory, medical diagnosis and variety of telecommunication devise. The development of optical memory devices with sensitivity to IR light sources provide undeniable opportunity for data storage and conversion in photonic circuits, artificial visual intelligence, and designing infrared optical devices by integration of low bandgap 2D materials in memory units. In this view, heterostructured MoS2/PbS van der Waals optical memory devices are introduced, which response efficiently under wide wavelength of 880 nm to 1940 nm (Figure 6.24f) [95]. The mechanism of heterostructured optical memory unit is based on the generation of photo-generated holes in PbS layer close to the interface of heterostructures. The injection of photo-generated carriers from PbS to the MoS2 film modulates the conductivity of MoS2 2D device (Figure 6.24f). It was reported that the high photoresponsivity of 1.2 × 104 A/W and the retention time of 104 s was observed with multilevel storage for this units [95].
Data Link Control for Optical Network

Higher layers: This layer consists of three planes – user plane, control plane and management plane. User plane: It provides for user information transfer along with associated controls which are flow control and error controlControl plane: It does call control and connection control functionsManagement plane: It also does management functions related to the system as a whole, providing coordination between all the planes and layer management managing functions relating to the resources and parameters residing in its protocol entities.
Network SwitchingConcepts
Published in Jerry C. Whitaker, Electronic Systems Maintenance Handbook, 2017
In the future telecommunication network infrastructure, both the narrowband services of today and emerging broadband services will be supported by an integrated B-integrated services digital network (B-ISDN). ATM has been adopted by the International Telecommunications Union (ITU-T) as the core technology to support B-ISDN transport. ATM is a high-speed, integrated multiplexing and switching technology that transmits information using fixed-length cells in a connection-oriented manner. Physical interfaces for the user-network interface (UNI) of 155.52 Mb/s and 622.08 Mb/s provide integrated support for high-speed information transfer and various communication modes, such as circuit and packet modes, and constant/variable/burst bit-rate communications.

The information exchange and control activities between people and machines occur via the human-machine interface; the various displays on the machine act on people, realising information transfer from machine to person. This process can be called human-machine interaction. This allows the interactivity of interpersonal communication. That is, people or things can achieve an effective dialogue with the machine. Interaction is the process of information transmission and the interface is the means by which this interaction is achieved (Strausser and Kazerooni 2011; Yin, Fan, and Xu 2012). Human-machine interaction should first help people to express their own opinions and ideas while simultaneously obtaining information, knowledge, and models from the machine. Therefore, the design of a human-machine interface and the interaction mode are a vital part of system design. Human-machine interface design should make usability the primary goal and obey the following principles: (1) place users under control; (2) reduce users’ memory burden; and (3) maintain interface consistency (Jeong-Su et al. 2003).
Information quality focused value stream mapping for the coordination and control of production processes
Published in International Journal of Production Research, 2021
For a structured implementation of the developed improved value stream, the necessary information flows to coordinate and control the process steps have to be modelled. To model information flows within a value stream map, Lewin et al. (Lewin, Voigtlander, and Fay 2017) defined which elements have to be represented. These are information source and sink, information transfer, information processing, and storage media. To accommodate for them, the structure and the icons of the classical VSM have been extended using additional icons, allowing a more detailed illustration of the information flows and considering IQ. The icons are illustrated in Figure 5, the resulting structure of the value stream map after the modelling of information flows is illustrated in Figure 6.
An analysis of the accuracy of the P300 BCI
Published in Brain-Computer Interfaces, 2018
The main measure of quality for the P300 speller is its accuracy: that is, the ratio between the number of correctly detected symbols to the number of attempted ones, which we will denote the symbol selection accuracy. Note that this quantity is not the accuracy of the single-trial classification problem described above (the ‘classification accuracy’): we consider every symbol rather than every stimulus. The specific method of estimating this ratio may vary from one study to another, and can be calculated either online or offline. Other quality measures include the Information Transfer Rate and the Practical Bit Rate [8,9], both of which attempt to represent the channel capacity of the BCI. While the information transfer rate and the practical bit rate hold a different meaning, they are both uniquely determined by symbol selection accuracy, so here we will address accuracy alone.
