Traditional approaches for developing automation systems consider system itself hardly can be changed. Current challenges in automation applications include the need of autoreconfiguration in response to process changes or event triggering. In order to face these requirements, new automation methodologies are necessary. Component-based technologies, initially defined for achieving efficient, structured and reusable designs can also be used to achieve adaptation. In this work, an IEC 61499-based framework that uses the concept to deal with reconfiguration issues is presented. The final output of the framework is a distributed system IEC61499 compliant. A new concept, the communication channel, is introduced providing a new abstraction layer to deal with communication between components. The joint use of automation components and communication channels allows defining complex automation systems in an easy way.

This study examines teleworkers’ job satisfaction related to the use of and satisfaction with a variety of communication channels and workers’ personality type. U.S. teleworkers ( N = 384) completed an online survey and self-reported on dimensions of communication channel satisfaction, job satisfaction, and personality. Results indicated that extraversion, openness, agreeableness, and conscientiousness are positively correlated with job satisfaction. Additionally, significant moderating effects were found for the relationship between openness and phone and video communication, and agreeableness and phone communication on job satisfaction. Findings from this study yield important practical implications for organizations including suggestions for optimizing communication satisfaction for employees of differing personality types and recommendations to help organizations effectively hire and retain teleworkers.

Traditional Approaches

The data from remote sensing satellites provide opportunities to acquire information about land at varying resolutions and has been widely used for change detection studies. A large number of change detection methodologies and techniques utilizing remotely sensed data have been developed, and newer techniques are still emerging. In this paper, a novel supervised approach of change detection using Support Vector Machine (SVM) and super pixels is proposed. In the formulation of change detection, SVM is modeled as a binary classifier to get the final output as “Change” and “No-Change” information. A relevant feedback mechanism is also included in to the change detection strategy so that it adapts in accordance with user preferences. Both ground truth and relevance feedback are collected using the developed GUIs. Comparison of the proposed approach with three other techniques of change detection is done via the experiments conducted on three multitemporal datasets. It is observed that the supervised, super pixel based change detection strategy gives superior results compared to traditional approaches of change detection. It is also seen that the usage of relevance feedback fine-tunes the results of change detection and acts as a desirable post-change detection process.

BACKGROUND Data collected by health care organizations consist of medical information and documentation of interactions with patients through different communication channels. This enables the health care organization to measure various features of its performance such as activity, efficiency, adherence to a treatment, and different quality indicators. This information can be linked to sociodemographic, clinical, and communication data with the health care providers and administrative teams. Analyzing all these measurements together may provide insights into the different types of patient behaviors or more accurately to the different types of interactions patients have with the health care organizations. OBJECTIVE The primary aim of this study is to characterize usage profiles of the available communication channels with the health care organization. The main objective is to suggest new ways to encourage the usage of the most appropriate communication channel based on the patient’s profile. The first hypothesis is that the patient’s follow-up and clinical outcomes are influenced by the patient’s preferred communication channels with the health care organization. The second hypothesis is that the adoption of newly introduced communication channels between the patient and the health care organization is influenced by the patient’s sociodemographic or clinical profile. The third hypothesis is that the introduction of a new communication channel influences the usage of existing communication channels. METHODS All relevant data will be extracted from the Clalit Health Services data warehouse, the largest health care management organization in Israel. Data analysis process will use data mining approach as a process of discovering new knowledge and dealing with processing data extracted with statistical methods, machine learning algorithms, and information visualization tools. More specifically, we will mainly use the k-means clustering algorithm for discretization purposes and patients’ profile building, a hierarchical clustering algorithm, and heat maps for generating a visualization of the different communication profiles. In addition, patients’ interviews will be conducted to complement the information drawn from the data analysis phase with the aim of suggesting ways to optimize existing communication flows. RESULTS The project was funded in 2016. Data analysis is currently under way and the results are expected to be submitted for publication in 2019. Identification of patient profiles will allow the health care organization to improve its accessibility to patients and their engagement, which in turn will achieve a better treatment adherence, quality of care, and patient experience. CONCLUSIONS Defining solutions to increase patient accessibility to health care organization by matching the communication channels to the patient’s profile and to change the health care organization’s communication with the patient to a highly proactive one will increase the patient’s engagement according to his or her profile.

The article analyzes the influence of errors from elastic deformations on the accuracy of processing in the conditions of complex automation. Different variants of multi-tool processing are considered: parallel processing, when different tools are alternately, one after the other, involved in the processing of the workpiece surfaces, and parallel-sequential processing, when different surfaces of the workpiece are processed simultaneously by several tools located in the working position. Design automation in machine-building production is part of the complex problem of automation of engineering work in all areas of the functioning of a modern production system. Therefore, when creating design automation systems, its connections in the general complex of automation of engineering activities in the production cycle should be taken into account. In general, the automation of the engineer's work is task planning, design and technological preparation of production, and management of the production system. The choice of favorable cutting modes for multi-tool processing is a difficult task, since, along with taking into account the features of each individual tool, it is necessary to make a general analysis of the entire setup, i.e. the set of tools used on the machine, and the distribution of processing transitions among them. Machine-building production is currently characterized by the desire to constantly update the range of released products. The requirements of multi-product manufacture can be met under the condition of its automation, which covers both the automation of production preparation and management. The article provides recommendations for reducing the error from elastic deformations in the conditions of complex automation.

Use Of Social Media

Social media has become an integral part of many people's lives around the world. The main use of this communication channel is to connect with social circles. It is also widely used for commercial and business purposes. Governments are also keen to use social media as an alternative to the traditional communication channels. Nonetheless, when the level of use of social media in the government is compared to other fields, a clear gap becomes apparent. This chapter investigates the adoption of social media as a communication channel between citizens, public agencies and government departments; and considers a wide range of factors that affect the issue from the perspective of public agencies. This chapter presents an extensive literature review and proposes a framework that organises the critical factors that affect public agencies' efforts while implementing social media. We also provide a list of hypotheses to validate and evaluate the significance of these factors.

Various development and validation methods for cyber-physical systems such as Controller-Hardware-in-the-Loop (C-HIL) testing strongly benefit from a seamless integration of (hardware) prototypes and simulation models. It has been often demonstrated that linking discrete event-based control systems and hybrid plant models can advance the quality of control implementations. Nevertheless, high manual coupling efforts and sometimes spurious simulation artifacts such as glitches and deviations are observed frequently. This work specifically addresses these two issues by presenting a generic, standard-based infrastructure referred to as virtual component, which enables the efficient coupling of simulation models and automation systems. A novel soft real-time coupling algorithm featuring event-accurate synchronization by extrapolating future model states is outlined. Based on considered standards for model exchange (FMI) and controls (IEC 61499), important properties such as real-time capabilities are derived and experimentally validated. Evaluation demonstrates that virtual components support engineers in efficiently creating C-HIL setups and that the novel algorithm can feature accurate synchronization when conventional approaches fail.

Facilitating students' chemical literacy is a focal point of current science education. This study examines views of chemists and chemistry teachers on chemical literacy and, more broadly, on scientific literacy of four kinds of stakeholders: scientists, teachers, STEM students, and the educated public. We explored the views of 347 participants, representing the four stakeholder groups with diversified scientific literacy, and an Ask-a-Scientist public website as a communication channel for facilitating chemical literacy through posing questions. Research tools included interviews, open-ended questionnaires, and questions retrieved from the website. We found that the questions posed on the website expressed a range of levels of chemical literacy that the students had constructed. The stakeholder groups expressed diverse perspectives of their experiences using various types of communication channels, arguing for the need to encourage students to pose questions and receive scientists' responses. Our study is placed in the larger context of scientific literacy and communication channels, as it takes the example of chemical literacy, with a focus on communications among scientists and chemistry teachers in the context of an Ask-a-Scientist website. It has established a link between responses of various stakeholders and the literature definitions regarding scientific literacy with focus on chemical literacy. From a practical viewpoint, the study presents a productive communication channel for posing questions in the context of chemistry and other sciences. Methodologically, this study includes the design of tools for analyzing both the views of different stakeholders and for evaluating the complexity level of chemistry questions, which might serve chemistry educators.
