One of the main challenges in the development of tools and methodologies for a multiprocessor realtime embedded system is to reuse already developed software, but at the same time obtaining low memory footprint, low energy consumption, and minimal area, obviously addressing the real-time constraints. This work aims to face these problems at the middleware level.We show that adaptations in the platform architecture, for instance exploring hardware implementations of middleware services, such as task scheduling and communication, can drive better gains in application requirements like energy and performance, which are essential for embedded applications. This approach is coupled with a high flexibility in choosing either a hardware or a software implementation, because services are encapsulated into objects and the application development and the design space exploration at middleware level can be performed independently from each other, in a fully transparent way. Furthermore, the use of the object-oriented approach reduces time-to-market and development costs.

Advances in technology call for a parallel evolution in the software. New techniques are needed to support this dynamism, to track and guide its evolution process. This applies especially in the field of embedded systems, and certainly in Wireless Sensor Networks (WSNs), where hardware platforms and software environments change very quickly. Commonly, operating systems play a key role in the development process of any application. The most used operating system in WSNs is TinyOS, currently at its TinyOS 2.1.2 version. The evolution from TinyOS 1.x and TinyOS 2.x made the applications developed on TinyOS 1.x obsolete. In other words, these applications are not compatible out-of-the-box with TinyOS 2.x and require a porting action. In this paper, we discuss on the porting of embedded system (i.e., Wireless Sensor Networks) applications in response to operating systems’ evolution. In particular, using a model-based approach, we report the porting we did of Agilla, a Mobile-Agent Middleware (MAMW) for WSNs, on TinyOS 2.x, which we refer to as Agilla 2. We also provide a comparative analysis about the characteristics of Agilla 2 versus Agilla. The proposed Agilla 2 is compatible with TinyOS 2.x, has full capabilities and provides new features, as shown by the maintainability and performance measurement presented in this paper. An additional valuable result is the architectural modeling of Agilla and Agilla 2, missing before, which extends its documentation and improves its maintainability.

Network security technology ensures secure data transmission in network. Meanwhile, it brings extra overhead of security system in terms of cost and performance, which seriously affects the rapid development of existing high-speed encryption systems. The existing encryption technology cannot meet the demand of high security, low cost and high real-time. For solving above problems, an ECC encryption engine architecture based on scalable public key cipher and a high-speed configurable multiplication algorithm are designed. The algorithm was tested on FPGA platform and the experiment results show that the system has better computation speed and lower cost overhead. By comparing with other systems, our system has benefits in terms of hardware overhead and encryption time ratio

Administrative Responsibility

The article is devoted to the consideration of problematic aspects of the implementation of administrative responsibility for non-payment of child support, is used in the form of socially useful work. In particular, the essence of this type of administrative penalty is revealed. The study focuses on the problematic issues that arise in the implementation of the imposed administrative responsibility in the form of socially useful work. A number of problems concerning the legal application of Article 183-1 of the Code of Ukraine on Administrative Offenses (hereinafter – the Code of Administrative Offenses) and ways of their solution have been outlined. Amendments to the current legislation of Ukraine are proposed in order to improve the implementation of resolutions in cases of administrative offenses. In particular, it is proposed to monitor the workload of the staff of the territorial bodies of the State Executive Service in Ukraine and analyze their staffing standards and functional responsibilities for the preparation of materials under Article 183-1 of the Code of Administrative Offenses. In addition, it was proposed to improve the organization of the performance of socially useful work by local governments by conducting appropriate explanatory work and methodological assistance to local governments in organizing the solution of this issue. The article proposes to transfer control functions to the executive body, and to improve the duty imposed on local governments to provide socially useful work is to improve, including amendments to the labor legislation of Ukraine. It is noted that when drawing up an administrative offense or making a decision in the case, it is necessary to find out the presence or absence of circumstances that for good reasons made it impossible for the debtor to pay child support, or the existing alimony arrears for the past period. The expediency of development of methodical recommendations for local self-government bodies concerning the order of definition and performance of socially useful works is substantiated.

Traditionally, routers and other network devices encompass both data and control functions in most large enterprise networks, making it difficult to adjust the network infrastructure and operation to large-scale addition of end systems, virtual machines, and virtual networks in industrial comprehensive automation. A network organizing technique that has come to recent prominence is the Software-Defined Network (SDN). A novel SDN based industrial control network (SDNICN) was proposed in this paper. Intelligent network components are included in a SDNICN. Switches in SDNICN provided fundamental network interconnection for the whole industrial control network. Network controller is used for data transmission, forwarding and routing control between different layers. Service Management Center (SMC) is essentially responsible for managing various services used in industrial process control. SDNICN can not only greatly improve the flexibility and performance of industrial control network but also meet the intelligence and informatization of the future industry.

The aim of the paper is to identify and discuss the suitability of the corporate governance structure of the Cooperative Banking Group (CBG) for preserving the distinctive characteristics of the cooperative credit banks (CCBs), such as mutuality and localism, as well as for guaranteeing the levels of capitalization, respecting the overall performance objectives. The analysis methodology uses a case study. The paper provides some reflections on the possible impacts of a radical change in the Italian cooperative credit system following the 2016 reform. The pilot model needs further adjustments in itinere, based on rigorous empirical tests conducted to confer on it the characteristics of universal applicability in the context of the CCBs. The major contribution of the paper is evident from the resulting interpretative process; the analysis conducted on a case study allows us to highlight the importance of the organizational dimension in the CCBs; the performances achieved by these, although with some distinctions throughout the Italian territory, are the result of the adequacy of the governance structures and the corporate control functions, which, even when partly outsourced, are always rigorously inspired by the logic of interconnection among those responsible for the functions themselves

The Relationship

The rapid development of economy brings serious environmental pollution problem. Green innovation, as the connection point between government environmental regulation measures and sustainable green development of enterprises, has become one of the important choices for the transformation and development of enterprises. Based on the classic model of “prisoner’s dilemma” in game theory, this paper deeply analyzes the relationship between green innovation and performance. It is found that it is easy to get into trouble if only relying on the spontaneous green innovation within the enterprise. Applying appropriate pressure outside the enterprise can promote the change of green innovation and bring long-term benefits to the enterprise.

Contemporary computer systems used in the industry are characterized by both an increase in the scale of supported industrial processes measured by the number of control devices and the increasing demand for information describing the underlying processes measured by the number of tags used in Supervisory Control and Data Acquisition (SCADA) systems and Manufacturing Execution Systems (MES). Classical industrial data servers based on the PC architecture are unreliable, expensive to operate and difficult to manage. The alternative is a new standard OPC UA communication interface that simplifies the communication protocol and increases the flexibility of the process data description which allow for the direct implementation of OPC UA servers in embedded devices. This paper presents an innovative approaches in the field of industrial data servers which are used for communication between control systems and SCADA or MES systems. The prototype industrial data server architecture has been implemented, run and tested on the platform of embedded system based on FPGA matrix with built-in FPGA Microblaze processor. The presented experimental results allow to evaluate the applicability of the proposed solution, the limits of the presented architecture and may be used for the improvement of the embedded industrial data servers' structure in subsequent implementations.

With the rapid development of IoT technology in recent years, higher requirements have been put forward for wireless communication technology. Low Power Wide Area Network (LPWAN) technology is emerging rapidly, the technology is characterized by low power consumption, low bandwidth, long-distance, and a large number of connections, and is specifically designed for Internet of Things applications. LoRa (Low Power Long Range Transceiver), as a typical representative of LPWAN technology, has been widely concerned and studied. This paper analyzes the performance of LoRa modulation in the tree topology network and analyzes the performance of LoRa modulation in the imperfect environment for point-to-point communication and multipoint-to-point communication. From theoretical analysis and performance simulation, it can be seen that the influence of frequency offset or multipath fading on LoRa signal is very obvious. However, when LoRa modulation is used for networking, multi-user interference will be introduced. Under the influence of many imperfect factors, the signal receiver performance of LoRa modulation will be difficult to guarantee. Because of these effects, Coordinated Multiple Points based on Timing Delay (DCoMP) is presented. Multiple nodes close to each other send the same data to the target node. Due to the inaccurate synchronization between nodes, there will be a certain relative delay when sending signals to the same target node. After the receiving node combines the signals of multiple nodes according to different relative delays, the reception performance of the signals can be improved. At the same time, the cooperative node can also actively adjust the signal sending time to improve the reception performance of the receiving node signal merging algorithm. LoRa modulation, by using DCoMP transmission, improves the reception of signals and thus the overall capacity of the system. Through the analysis of multipoint communication and single point communication, this paper is of great help to LoRa network deployment.
