Smart implements by leveraging ISOBUS: Development and evaluation of field applications

Increased labor scarcity and input costs, as well as the demand for ecologically more sound control of growing conditions while maintaining yield and quality in both viticulture as well as horticulture have proliferated the requirements for the current technologies such as implements and autonomous vehicles used in these domains. The increasing employment of such technology, however, brings up the issue of compatibility, in terms of data exchange, connectivity, and communication between the implements and autonomous vehicles used. Besides that, conducting the connection and communication in a standardized means adds more complexity to the issue. To properly address the above-mentioned issue, this work focused on developing a middleware that introduced the ISO 11783 standard-based communication to the setup for both, a weeder robot and a combination of a sprayer and a retrofitted tractor. The developed middleware also considered the information exchange with external systems such as real-time decision-making sensor systems and a farming controller to accurately carry out the field applications of weeding and spraying. The correctness of the weeding quality computation and the spraying coverage indicating the performance of the developed setups were verified before conducting in-field applications. The subsequent in-field weeding application indicated an adequate evaluation of the weeding quality with a variation from 94 to 100 % and zeros in the regions of the weeding path where the weeding was not necessary. The assessment of the spraying applications based on the comparison between the prescribed and the as-applied information showed a mean value of 1.08×104 mm3 m-2 for the absolute deviation from the maximum prescribed rate. Further analyses indicated that the as-applied rate varied with a deviation of 10 % during the field application, which was below the defined threshold.

Perancangan Aplikasi Kompresi File Video Menggunakan Algritma SPIHT (Set Partioning In Hirarcical Tress)

Video files have a large enough capacity, and to access them takes a long time, so a data compression technique is needed. In this case the video file will be compressed using the SPIHT (Set Partitioning In Hierarchical Trees) algorithm, SPIHT (Set Partitioning In Hierarchical Trees) is a video file compression capable of achieving a high compression ratio. Problems that arise due to the large file size include the wasteful storage media used, as well as more time in terms of data exchange, data transfer over the internet is a big problem in Indonesia because of the very low download and upload speeds. To overcome this problem, data compression techniques are needed. The concept of compression was born as a real solution to problems regarding the space needed to store various digital files, including the MKV (Matroska Video) format video files. The compression technique is a technique that compresses files so that they become smaller in size while maintaining the quality of the representation of the file. Through the compression process of MKV (Matroska video) format video files using the SPIHT (Set Partioning In Hirarcical Tress) algorithm, it is hoped that in the future this compression system will have a major effect on video file storage and can increase storage and it is also hoped that this algorithm can be used for other objects to be compressed.

An Overview of EV Roaming Protocols

Roaming in electric mobility (EV roaming) enables EV users to make use of any charging station belonging to other networks with only a single user registration based on roaming agreement between operators. This paper presents an overview of the functionalities of the four major existing EV roaming protocols, namely the Open Charge Point Interface (OCPI), the Open InterCharge Protocol (OICP), the Open Clearing House Protocol (OCHP), and the eMobility Inter-operation Protocol (eMIP). This paper focuses on how each EV roaming protocol works in terms of data exchange with the Open Charge Point Protocol (OCPP) which is the de-facto protocol embedded in many charging stations available in the market. Related actors and their roles that are defined in each protocol will be presented. Examples are given in the form of a sequence diagram in order to depict the interaction between actors in the case of user registration, start a charging session, stop a charging session, and billing. This paper concludes that employing the sequence diagram is one effective method to achieve a fast learning curve while studying the EV roaming protocols.

Enhancing environmental and energy monitoring of residential buildings through IoT

Solutions for monitoring and control of the digital technologies in the residential and tertiary sector are lagging in terms of data exchange and easy deployment. The question arises whether current technologies allow cross-functional integration of data. This paper explores an IoT (Internet of Things) solution in controlling the HVAC system and monitoring of environmental, electric and comfort parameters in a real building. The implemented IoT solution proved to be flexible in terms of data exchange, deployment and debugging time in small and medium-size buildings and thus the IoT integration-based approach to be more efficient. This approach opens new possibilities for a wider set of beneficiaries. As future research, we are considering both extending our solution to other buildings within the university campus premises and on developing predictive analytics services.

Application of OSPF Network in Spanning Tree Protocol Method to Prevent Looping Routing

Network is a basic thing that must exist in an agency or company, because the network can facilitate us in terms of data exchange and data transfer. In this study the application of the OSPF network to the Spanning Tree Protocol method to maintain Looping Routing using the Graphical Network Simulator 3 (GNS 3) simulator is expected to be the main objective in facilitating work completion, especially in terms of communication system data collection. With the help of Routing which serves to determine the route traveled by a packet that originates from a source node to the destination node on the network. Open shortest path first (OSPF) is one of the dynamic routing protocols that uses a link-state algorithm to build and calculate the shortest path to all known destinations. STP functions as a protocol for managing connections using the spanning tree algorithm.

Assessment of model-based data exchange between architectural design and structural analysis

The emerging availability of numerous model-based design and analysis tools promises high interoperability in terms of data exchange, thus shorter planning cycles and higher design quality. However, seamless transfer of digital models across domains without significant data inconsistencies is still a major challenge in the practice. This paper aims to identify the procedural problems in the data transfer between architectural design and structural analysis and propose improvement.This study reviewed the current data exchange practices, and concluded that data exchange based on the industry foundation classes (IFC) is the most spread in the research and software tools supporting architecture, engineering and construction industry. The study also analyzed the processes which affect the IFC-based data exchange. The interoperability of software tools through IFC files was tested in a comparative study. The testing results are reflected on the processes influencing data exchange, identifying the procedural problems and recommending the improvements.Upon conducted analysis and testing, the authors propose the following strategies for the systematic improvement of the data exchange: (a) introducing interpretation rules in the data exchange standards; (b) focusing on multiple domain-specific building data schemas instead of on the integrated schema; and (c) developing a new certification process based on the domain-specific building data schema. The improvement proposal supported by the analysis provides a roadmap for the development of model-based exchange between architectural design and structural analysis.

FLAT: Federated lightweight authentication for the Internet of Things

Federated Identity Management schemes (FIdMs) are of great help for traditional systems as they improve user authentication and privacy. In this paper, we claim that traditional FIdMs are mostly cumbersome and then ill-suited for IoT. As a solution to this problem, we came up with Federated Lightweight Authentication of Things (FLAT), namely a federated identity authentication protocol exclusively tailored to IoT. FLAT replaces weighty protocols and public-key cryptographic primitives used in traditional FIdMs by lighter ones, like symmetric cryptographic primitives and Implicit Certificates. Our results show that FLAT can reduce the data exchange overhead by around 31% when compared to a baseline solution. Also, the FLAT Client, the role played by an IoT device in the protocol, is more efficient than the baseline Client in terms of data exchange, storage, memory, and computation time. Our results indicate that FLAT runs efficiently, even on top of resource-constrained devices like Arduino.

Privacy-driven Design of Learning Analytics Applications – Exploring the Design Space of Solutions for Data Sharing and Interoperability

Studies have shown that issues of privacy, control of data, and trust are essential to implementation of learning analytics systems. If these issues are not addressed appropriately systems will tend to collapse due to legitimacy crisis, or they will not be implemented in the first place due to resistance from learners, their parents, or their teachers. This paper asks what it means to give priority to privacy in terms of data exchange and application design and offers a conceptual tool, a Learning Analytics Design Space model, to ease the requirement solicitation and design for new learning analytics solutions. The paper argues the case for privacy-driven design as an essential part of learning analytics systems development. A simple model defining a solution as the intersection of an approach, a barrier, and a concern is extended with a process focussing on design justifications to allow for an incremental development of solutions. This research is exploratory of nature, and further validation is needed to prove the usefulness of the Learning Analytics Design Space model.
