IoT technology is widely applied to many areas, including agriculture. The smart farming design and implementation deal with farm operations and management effectively. The aim of this research enables supporting a vermiculture smart farming kit based on IoT technology. The layered architecture design is represented to support the deployment of sensors, networks, monitoring systems, data collections, and watering decision system. Information flow diagram is proposed to improve how the web application of our smart kit system can implement based on the system requirements. The evaluations of the smart kit are investigated to deal with consistency and effectiveness comparing between a traditional and the smart kit of earthworm vermicomposting. The gaps of farmers' needs can be satisfied to advance the better solutions of the smart farming kit.

The authors cannot comprehensively determine all of the vulnerabilities to an attack only from requirements descriptions. To resolve the problem, the authors propose a method for eliciting security requirements using the information about system architecture. The authors convert a use-case description into a variation of a data flow diagram called an asset-flow diagram (AFD). The authors then refine the AFDs based on a processor deployment diagram (PDD), which gives information about a system architecture. By using vulnerabilities patterns to an attack, the authors distinguish vulnerabilities to the attack that can be identifiable in AFDs from remaining vulnerabilities to the attack. To prohibit the former vulnerabilities, security requirements are defined as countermeasures and/or modification of existing requirements. To prevent the latter vulnerabilities, security requirements are defined as design and implementation constraints. Through an evaluation of a web application, the authors show that our method enables us to elicit security requirements against several different attacks in different system architectures.

System Information

The purpose of this paper is to present the design and implementation of a system that combines the hardware with the software resulting in an intelligent system of sockets that can be controlled and monitored remotely. The Arduino Mega 2560 performs the basic function and provides the information gathered from the sensors (Hall effect current sensor, motion sensor, dual temperature and humidity sensor). General system information is displayed locally on an LCD screen. The system protects the connected equipment by disconnecting the power supply in case of hazard; but can also be controlled remotely via a web application by the user.

Configuration Methodology

Low-carbon product design involves a redesign process that requires not only structural module modification, but more importantly, generating innovative principles to solve design contradictions. Such contradictions include when current design conditions cannot satisfy design requirements or there are antithetical design goals. On the other hand, configuration tasks in the reconfiguration process are interdependent, which requires a well-scheduled arrangement to reduce feedback information. This study proposes an effective configuration methodology for low-carbon design. Firstly, configuration tasks and configuration parameters are designated through quality characteristics, and the directed network along with the associated values of configuration tasks are transformed into the design structure matrix to construct the information flow diagram. Then, the Extenics-based problem-solving model is presented to address design contradictions: low-carbon incompatibility and antithetical problems are clarified and formulated with a basic-element model; extensible and conjugate analysis tools are used to identify problematic structures and provide feasible measures; the Gantt chart of measures execution based on the information flow diagram is constructed to reduce feedback and generate robust schemes with strategy models. The methodology is applied to the vacuum pump low-carbon design, the results show that it effectively solves contradictions with innovative design schemes, and comparative analysis verifies the performance of Extenics.

Information And Communication

Transaction cost theory has often been used to support the use of information and communication technology (ICT) to reduce imperfection in the economic system. Electronic markets and hierarchies have repeatedly been described as solutions to inefficiencies in the organisation of transactions in complex and uncertain settings. Far from criticising this assumption, this paper highlights the limits associated with this application of transaction cost theory that has been prevalent in IS research. Building on the concepts first proposed by Ciborra, the paper argues that information-related problems represent only some of the elements contributing to transaction costs. These costs also emerge due to the interdependencies among the various factors contributing to their growth. The study of the consequences associated with ICT design and implementation, grounded in transaction cost theory, should consider the overall implication associated with the adoption and use of ICT and not only the direct effect on problems associated with information flow, distribution, and management.

Abstract System requirements and system design for integrating a production rule program and a computer aided design system are presented. An implementation using a commercially available graphics modeling system is described. A “suggestive mode” interface is programmed as an example with application to design for automated assembly. Initial use of the implementation indicates that encoding production rules is more difficult than with conventional text-only knowledge-based systems, but that this system is a more effective way to use artificial intelligence techniques in design.
