Human-Device Interaction in the Life Science Laboratory.

The interaction of the human user with equipment and software is a central aspect of the work in the life science laboratory. The enhancement of the usability and intuition of software and hardware products, as well as holistic interaction solutions are a demand from all stakeholders in the scientific laboratory who desire more efficient workflows. Shorter training periods, parallelization of workflows, improved data integrity, and enhanced safety are only a few advantages innovative intuitive human-device-interfaces can bring. With recent advances in artificial intelligence (AI), the availability of smart devices, as well as unified communication protocols, holistic interaction solutions are on the rise. Future interaction in the laboratory will not be limited to pushing mechanical buttons on equipment. Instead, the interplay between voice, gestures, and innovative hard- and software components will drive interactions in the laboratory into a more streamlined future.

Study of Sharing Patient Information by Nurses Between Inpatient and Outpatient Wards in Japan.

Shortening hospital stays increases communication needs between nurses in inpatient and outpatient wards. Smooth information sharing is required to reduce the workload of nurses and improve the quality of patient care. However, electronic medical records (EMR) system does not have sufficient functions to support information sharing between wards, because EMR has been developed mainly for recording. This study led to three improvements; unified communication tool, common patient list linked to EMR, and outpatient nursing diagnosis.

QSPCA: A Two-Stage Efficient Power Control Approach in D2D Communication for 5G Networks

The existing literature on device-to-device (D2D) architecture suffers from a dearth of analysis under imperfect channel conditions. There is a need for rigorous analyses on the policy improvement and evaluation of network performance. Accordingly, a two-stage transmit power control approach (named QSPCA) is proposed: First, a reinforcement Q-learning based power control technique and; second, a supervised learning based support vector machine (SVM) model. This model replaces the unified communication model of the conventional D2D setup with a distributed one, thereby requiring lower resources, such as D2D throughput, transmit power, and signal-to-interference-plus-noise ratio as compared to existing algorithms. Results confirm that the QSPCA technique is better than existing models by at least 15.31% and 19.5% in terms of throughput as compared to SVM and Q-learning techniques, respectively. The customizability of the QSPCA technique opens up multiple avenues and industrial communication technologies in 5G networks, such as factory automation.

Interconnection In the Convergence Era (IP-BASED Interconnection Regulation Challenges)

The IP age of networks and services is increasing very quickly. Starting from its VoIP, NGN, and IMS to today's IP services landscape, which includes fixed and mobile high-definition (HD) voice, HD video calling, unified communications (UC), video conferencing, and telepresence, cooperation, instant messaging (IM), and the rich communication suite (RCS). Convergence is one of the most significant current trends in the ICT sector. It has changed the way services are delivered and obscured the distinction between fixed and mobile services. The transition to Next-Generation Networks (NGN) is the most important next phase in the ICT sector's convergence-driven evolution. In the realms of NGN, VoIP, and IMS, there is no PSTN equivalent; instead, there are "IP islands " that locate the total value of an IP service. The next basic step is to expand the arrive of those services across a totally interconnected cross-network premise in order to maximize their overall esteem among their target audiences. The liberalization of infrastructure services depends on managing the interconnection interface between the competitive and regulated sectors. These paper outlines regulation issues raised by IP-based interconnection and examine the current practices and procedural ways that being developed to address these concerns.

Observer-Based Spacecraft Formation Coordinated Control via a Unified Event-Triggered Communication

This article addresses the formation tracking control problem for multiple spacecraft systems subject to limited communication resources and external disturbances. Considering that only a subset of the follower spacecraft can have access to the motion states of the dynamic leader, an event-based distributed observer is first developed to reconstruct the leader's information. Subsequently, to achieve the accompanying flight of the follower spacecraft around the leader with a desired formation configuration, for each follower spacecraft, a distributed event-triggered coordinated controller is proposed. In particular, by embedding simultaneously the position information and observer output into the triggering function, a novel unified event-triggered mechanism is designed to schedule information transmission in multiple spacecraft systems. The salient characters of the distributed coordinated control scheme are twofold: unnecessary occupancy of communication resources can be avoided significantly; and asymptotic stability of the whole closed-loop system is guaranteed without resorting to the separation principle. Finally, numerical simulations are carried out to illustrate the efficiency of the theoretical results.

4C: A Computation, Communication, and Control Co-Design Framework for CAVs

Connected and autonomous vehicles (CAVs) are promising due to their potential safety and efficiency benefits, and have attracted massive investment and interest from government agencies, industry, and academia. With more computing and communication resources available, both vehicles and edge servers are equipped with a set of cam-era-based vision sensors, also known as Visual IoT (VIoT) techniques, for sensing and perception. Tremendous efforts have been made to achieve programmable communication, computation, and control. However, they are conducted mainly in silo mode, limiting the responsiveness and efficiency of handling challenging scenarios in the real world. To improve the end-to-end performance, we envision that future CAVs require co-design of communication, computation, and control. This article presents our vision of the end-to-end design principle for CAVs, called 4C, which extends the VIoT system by providing a unified communication, computation, and control co-design framework. With programmable communications, fine-grained heterogeneous computation, and efficient vehicle controls in 4C, CAVs can handle critical scenarios and achieve energy-efficient autonomous driving. Finally, we present several challenges to achieving the vision of the 4C framework.

Bandwidth assessment of scheduled and unscheduled communication in hybrid networked control system

ABSTRACT The large integrated industrial applications require unified communication to combine data from multiple domains forming a hybrid network. The scheduling of network access time to multi-domain data in an industrial hybrid network is a challenging task. This paper extends the contribution of the network model mentioned in the literature to assess the bandwidth of both the scheduled and unscheduled communication in hybrid networked control systems. This paper's contribution includes four phases as follows: a) simulation of a hybrid networked control system (h-NCS) consists of four domains with different bandwidth allocations for an application of transmitting a data packet over a network stack from wired node to the wireless node. b) the mathematical demonstration of TCP and IEEE802.11b related to domains incorporated in h-NCS for data transmission. c) the normalisation of the bandwidth of the network access time for both scheduled and unscheduled data packets of h-NCS by implementing Dempster’s rule of combination. d) comparison analysis of proposed h-NCS with the traditional NCS for network access time utilised by both the scheduled and unscheduled data transmission.

Development of Drone-Mounted Multiple Sensing System with Advanced Mobility for In Situ Atmospheric Measurement: A Case Study Focusing on PM2.5 Local Distribution.

This study was conducted using a drone with advanced mobility to develop a unified sensor and communication system as a new platform for in situ atmospheric measurements. As a major cause of air pollution, particulate matter (PM) has been attracting attention globally. We developed a small, lightweight, simple, and cost-effective multi-sensor system for multiple measurements of atmospheric phenomena and related environmental information. For in situ local area measurements, we used a long-range wireless communication module with real-time monitoring and visualizing software applications. Moreover, we developed four prototype brackets with optimal assignment of sensors, devices, and a camera for mounting on a drone as a unified system platform. Results of calibration experiments, when compared to data from two upper-grade PM sensors, demonstrated that our sensor system followed the overall tendencies and changes. We obtained original datasets after conducting flight measurement experiments at three sites with differing surrounding environments. The experimentally obtained prediction results matched regional PM trends obtained using long short-term memory (LSTM) networks trained using the respective datasets.

Microgrid monitoring system based on aliyun

With the increasing demand for energy, microgrid security is becoming more and more important. Therefore, how to monitor the microgrid effectively and continuously has received great attention. If the real-time on-line evaluation is realized, it is possible to improve the performance of power generation and load distribution. The current microgrid monitoring system is only to establish a monitoring center, and then send the information to the center through the equipment. However, staff need to be stationed in the monitoring center, the labor cost is too high. The scheme of microgrid monitoring system proposed in this paper makes a reasonable application of Aliyun technology. The information and data collected by the local device is passed into the gateway by specifying a unified communication protocol. The local device can provide the power, waveform and operation status of the whole power grid, in addition to displaying the power of the whole system, it also displays the power information of each element separately. The gateway then transmits the data through the optical fiber and wireless network to the CVM through the conversion protocol, and the operation of the microgrid can be monitored in real time by using external devices.

It is concluded that there is no epidemiological prevention and combat planning on the campus and surroundings and that it is necessary to strengthen the unified and integrated communication channel between institutions and the community.

IMPACT OF ICT ON DEVELOPMENT OF COMMUNICATION SKILLS OF PROSPECTIEVE TEACHERS

ICT is an extensional term for Information technology that stresses the role of unified communication and integration of telecommunications with computers as well as necessary software and hardware tools. Soft Skills are characteristic traits and interpersonal skills that identifies a person’s relationship with others. Certain examples of Soft Skills are Communication, Instructions, Mentoring etc. According to M. Bridget Duffy “Rather than making technology the center piece of care, it’s time to start using it to restore human connections and return people to purpose. The interplay between humans and technology goes to the heart of larger issues, in which soft skills play a key role. The most striking and latest innovations in the field of education is the integration of ICT in education. It has expanded the range of resource available for any subject- specific learning. Teachers play a pivotal role in developing the future generation of students. Therefore, they have to be properly guided so that they could enhance their competences. Proper educational training is the key element to move towards sustainability. This paper emphasizes on the importance and development of Soft Skills with the help of ICT, in the prospective teachers. So, that they can achieve professional competence. This study is based on quantitative research approach. The population of the study was prospective teachers of Patna. 100 samples from 4 different colleges of Patna were selected randomly. Self constructed and validated tools were used for data collection. Findings of the study shows that that there is significant difference in mean scores of communication skills on the basis of gender and their educational qualification while there is no significant difference in mean scores of communication skills on the basis of their marital status of prospective teachers. Significant relationship was found in the score of ICT and Communication skills of prospective teachers.

Modeling of quality of experience for web-based unified communications with perceptual dimensions

The integration of heterogeneous communication services and devices has led to paradigm shift towards unified communications, which promise to improve productivity and lifestyle by creating the digitally connected life and work environment. The increasing use of various devices for accessing web-based rather than native unified communication is expected to initiate the rise of interest among various parties included in the service delivery chain in comprehension of the influence of different perceptual dimensions on user’s quality of experience. This paper presents a multidimensional analysis of quality of experience for web-based unified communication. The contribution of the paper is twofold. First, the multidimensional model, which quantifies the mutual relations between quality of experience and numerous perceivable dimensions of the experience that determine its quality is proposed. Second, the importance of distinct dimensions in terms of overall user perceived quality of experience for web-based unified communication is identified.

An Augmented Infocommunication Model for Unified Communications in Situational Contexts of Collaboration

Aim/Purpose: In this work, the authors propose an augmented model for human-centered Unified Communications & Collaboration (UC&C) product design and evaluation, which is supported by previous theoretical work. Background: Although the goal of implementing UC&C in an organization is to promote and mediate group dynamics, increasing overall productivity and collaboration; it does not seem to provide a solution for effective communication. It is clear that there is still a lack of consideration for human communication processes in the development of such products. Methodology: This paper is sustained by existing research to propose and test the application of an augmented model capable of supporting the design, development and evaluation of UC&C services that can be driven by the human communication process. To test the application of the augmented model in UC&C service development, a proof-of-concept mobile prototype was elaborated upon and evaluated, making use of User Experience (UX) and user-centred methods and techniques. A total of nine testing sessions were carried out in an organizational communication setup and recorded with eye tracking technology. Contribution: The authors argue that UC&C services should look at the user’s (human) natural processes to improve effective infocommunication and thus enhance collaboration. Authors believe this augmented version of the model will pave the way improving the research and development of useful and practical infocommunication products, capable of truly serving users’ needs. Findings: On evaluation of the prototype, qualitative data analysis uncovered structural problems in the proposed prototype which hindered the augmented model’s elements and subsequently, the user experience. Five out of eighteen identified interaction issues are highlighted in this paper to demonstrate the proposed augmented model’s validity, applied in UC&C services evaluation. Recommendations for Practitioners: Considering and respecting the user’s natural communication processes, practitioners should be able to propose and develop innovative solutions that truly enable and empower effective organizational collaboration. UC&C functionalities should be designed, taking the augmented model’s proposed elements and their pertinence in representing the human interpersonal communication phenomena into consideration, namely: Social Presence; Immediacy of Communication; Concurrency and Synchronicity. Recommendation for Researchers: This paper intends to demonstrate that the adoption and use of UTAUT technology characteristics, in conjunction with Synchronicity proposition, can be considered as a reference for human-centric design and the evaluation of UC&C systems. Impact on Society: To highlight the need to develop further research on this important topic of human collaboration mediated by technology inside organizations. Future Research: This research focused its attention on communication functionalities. However, collaboration can potentially be affected by other services that may be included in a UC&C system, such as scheduling, meetings or task management. Future research could consider employing this augmented model to evaluate such systems or proof-of-concept prototypes.

Opis postupka tunelovanja Q signalizacije u privatnim telekomunikacionim mrežama

Introduction/purpose: The article should specify the network signaling type Q-SIG, which is standardized especially for implementation in digital telecommunication networks of integrated services (ISDN), emphasizing the possibility of its further application in the Private Telecommunications Network of Integrated Services of the Serbian Armed Forces (PISN of SAF), i.e. in the Private Automatic Telephone Network of the Serbian Armed Forces (PATN of SAF). Methods: An analysis of the existing standards was performed: ECMA355 and ECMA-336 and a synthesis of the possibilities of their application in the PATN of SAF. Results: The procedure for the application of Q-SIG is processed in a situation when the peripheral parts of the PISN of SAF, which operate on the principle of transmission and circuit switching by TDM (Time Division Multiplexing), are connected via a central Core network with the IP (Internet Protocol), which operates on the principle of packet transmission and switching with the SIP (Session Initiation Protocol). A method of the application of the tunneling of encapsulated Q-SIG messages through the IP network, defined by ECMA-355 Standard, has been developed. The necessary functions for mapping the transmission of tunneled signaling messages Q-SIG and mapping voice (and other audio) information to media streams during VoIP (Voice over IP) communication through that network, which are defined by ECMA-336 Standard, are described. Conclusion: The application of ECMA-355 and ECMA-336 Standards is a new solution in the PATN of SAF with the use of the IP network to connect the IP PINX using the Q-SIG tunneling procedures and mapping functions for their transmission and transmission of audio signals. This then opens up a whole range of new possibilities that, with the growth of the Core network and their application, will rapidly contribute to the creation of a broad Telecommunication information system backbone for the implementation of real-time multimedia communications and the transition to Unified Communications (UC).

Fiber-optic communication line application for towed underwater vehicles

Utilization of towed unmanned vehicles for seabed relief survey in real time requires the use of technologies that allow high-speed, stable data transfer between the underwater towed body and the carrier vessel. This paper discusses technical solutions used to provide a unified communication system based on fiber optic technologies for towed vehicles manufactured in Institute of oceanology.

Integrated Robotics Architecture with Kansei Computing and its Application

Robots communicating with humans have been widely utilised in our society. This type of communication can be limited when only one robot is involved. Meanwhile, expressing the same unified mood and emotion is difficult when several robots are working. Furthermore, realising expressions representing different cultures in the context of a global society is also challenging. To address these issues, we propose an integrated robot architecture (IRA) providing a communication environment, in which various robots and devices can be combined. In this architecture, meta-level messages are communicated between various kinds of devices using a unified communication protocol. The framework of Kansei computing is integrated for realising non-verbal expression. This method makes it possible to express emotions with colours synchronised with each utterance, according to the characteristics of the device and required culture. This paper also presents a system prototype and verifies its feasibility.
