Wireless communication, identification and sensing technologies enabling integrated logistics: a study in the harbor environment

In the last decade, integrated logistics has become an important challenge in the development of wireless communication, identification and sensing technology, due to the growing complexity of logistics processes and the increasing demand for adapting systems to new requirements. The advancement of wireless technology provides a wide range of options for the maritime container terminals. Electronic devices employed in container terminals reduce the manual effort, facilitating timely information flow and enhancing control and quality of service and decision made. In this paper, we examine the technology that can be used to support integration in harbor's logistics. In the literature, most systems have been developed to address specific needs of particular harbors, but a systematic study is missing. The purpose is to provide an overview to the reader about which technology of integrated logistics can be implemented and what remains to be addressed in the future

Human-centred workplace: Re-finding physical document in an office workplace

Today’s typical busy schedules make it difficult for people to keep track, organize and search the documents they keep in their own office workplace. The consequences of less organized offices are often that people lose more time in searching for paper documents. To avoid the consequences of losing documents, some archive their physical documents according to their use and others place documents in highly visible areas. These strategies offer some comfort when searching the document, but the practice demands people to be somewhat organized. Even digital support for finding physical documents typically requires some organisation and order has observed. In this thesis, we describe a project that created a system, which does not require people to be orderly and aims at freeing people from the time-consuming job of sorting or sequencing their documents. The system generates and prints passive tags (Quick Response Code) on documents and uses cameras in the office to track changes in the document locations. The thesis describes the design, implementation and initial evaluation of the system ‘Human-centred workplace (HCW).

Towards Linking Virtual Models with Physical Objects in Construction using RFID:Review of Ontologies

Virtual models have in recent years proven their worth in practice relating to building design. Today virtual models of the complete project are created before the project is carried out in practice. The immediate advantages of this are great; it introduces fewer errors, gives a better production basis, improved clarity and enhanced communication methods compared to traditional 2D drafting methods. However, there is still much unutilized potential in the virtual models, especially in the construction and operation phases. It is expected that a digital link between the virtual models and the physical objects in the construction process can improve the information and knowledge handling from design to construction, operation and maintenance. The link can be created by use of Radio Frequency Identification (RFID) technology. This paper describes a review and assessment of existing ontologies relevant in relation to creating this link. The ontologies are categorised according to their applicability to specify technical services, resources, organisational relations, business processes and overall frameworks for ontology descriptions and their relations. It is concluded that, with few modifications the technical service and resource ontologies are applicable for industrial use and the meta, organisational and business process ontologies needs further development and industrial maturity to be applicable.

Valuation of online social networks - An economic model and its application using the case of Xing.com

Ubiquitous information technologies like RFID allow for immediate, extensive and fine-grained capture of real world information. Scalable and efficient networks for exchange of this vast amount of information amongst companies are crucial for the economic exploitation of benefits of ubiquitous information technologies. Existing networks bear several limitations like risks of single-point-offailures or bottlenecks, unequally distributed power and burdens as well as inflexibility through stringent structures and formats. In particular there is a need for improving the scalability of solutions and ensuring autonomy of network participants. In this paper we introduce a Peer-to-Peer-based architecture for exchanging distributed information, which are shared among participants of a supply chain facilitated with ubiquitous information technologies. This architecture builds on the wellestablished EPCglobal standards, but can be implemented as an autonomous network. Unlike other architectures it does not need central coordination mechanisms, because it is based on self-organizing Peer-to-Peer protocols. We argue that our architecture supports business processes especially of small and medium-sized enterprises better than other architectures. We provide a discussion about requirements for solutions and a simulation-based analysis of the proposed architecture

Paperspace : a novel approach to document management by combining paper and digital documents

Personal document management systems provide good support for storing and organizing digital documents. However, there are no computer tools that support organization of paper documents on our desks. We ran a study of people's organization of their office desk space with respect to their digital workspace. This study resulted in a set of requirements for a media bridging tool. Based on these requirements, we built a prototype media bridging tool called PaperSpace that uses computer vision to link paper and digital documents. The system also tracks piles of paper documents on the real desktop, and links those papers to digital documents stored in the computer. Digital documents can be sorted and grouped according to the physical layout of the corresponding papers on the desk. The system automatically creates digital piles of documents in a simulated desktop that reflect the paper piles on the real desktop. The user can access valuable information through the system, such as printing statistics, location of a printed document on the desk, and past projects and their documents. A two week user evaluation of the system showed interesting usage scenarios and future trends for improving user interaction

Tangible user interfaces : past, present and future directions

In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research

The current EU rules on bovine electronic identification systems: state of the art and its further development

Abstract. Regulation (EC) No 1760/2000 establishes a system for the identification of bovine animals and regulates the mandatory and voluntary labelling of beef and beef products. While bovine ear tags must bear an identifying code, the current European Union (EU) rules do not regulate electronic tags for bovine animal

RFID tags for the expedition of body part processing in large scale disaster victim identification incidents: A cost and feasibility pilot study

In 2001, over 2,000 lives were lost at the World Trade Center. Approximately 280,000 deceased victims were a result of the Asian tsunami of 2004, and 168 fatalities after the Oklahoma bombing in 1995. Whether the disaster incident is large or small, the legal responsibility falls on forensic investigators to positively identify every victim, for the purpose of returning the remains to their respective families. In forensic science and more specifically, disaster victim identification (DVI), an unforeseen incident can result in the demise of a mass of lives. Identifying the fallen victims is of vital importance. Highly skilled specialists and investigators are involved in the DVI processes in order to expedite the processing of body parts. However, a research gap remains in regard to the timeliness of human remain examinations at large scale DVI incidents. The expedition of DVI investigations is crucial as it impacts the number of positive identifications that are made, whilst issues such as decomposition may challenge forensic investigators. Radio Frequency Identification (RFID) technology is an advanced system that transmits a radio signal, in order to track and identify objects. This review aims to demonstrate how RFID technology has the ability to significantly decrease forensic examination and identification time of victims, through sub-dermal implantation of microchips into human remains. Although the cost of implementing RFID is a limitation, the technology has proven to be successful in several organisations on an international scale and has been effective through sub-dermal implantation in humans as well as animals. Through utilising RFID, forensic investigators and legal authorities will be equipped to conduct an expeditious DVI process and hence, determine a greater amount of positive deceased victim identifications
