In this paper we present a new methodology where teachers take into consideration the students’ perspective to find weaknesses in the educational system. By using this method, the system is capable to have a broad view and can adapt the school to meet the incredible pace of technology change. Our proposal here is to create a platform that is able to collect information from students' moods, using RFID tags to represent three different moods. Students can click on them to express how they feel.

Hierzu wurden Standards für den Aufbau und den Betrieb eines solchen multimedialen Museums entwickelt. Zentrales Element der Ausstellung ist die Mobilität der einzelnen Module und die stringente Ausrichtung auf die Bedürfnisse der Zielgruppen. Das Konzept des mobilen Museums ermöglicht eine jugendgerechte Wissensvermittlung unter Einbeziehung spielerischer Ansätze, die eine Möglichkeit der direkten Teilnahme bietet. So wird die mobile Ausstellung attraktiver und die User Experience gesteigert.

An Efficient Algorithm for RFID Reader Positioning for Coverage of Irregularly-Shaped Areas

These applications involve locating all tagged items automatically using available RFID readers. RFID readers are of two types, fixed and mobile. The number of readers required to cover an area depends on factors such as the properties of the reader, tag and the shape of the area to be covered.

This paper presents an algorithm to find the minimum number of fixed RFID readers required for complete coverage of an area of irregular shape. This approach, which applies the Graham’s scan algorithm of computational geometry, can be used for buildings, warehouses, etc., of any shape. The algorithm determines the required number of readers by considering the interrogation range of the reader. A methodology of forming the convex hull/polygon covering the irregular area, and subsequently placing the readers at specified locations within the polygon based on the properties of the reader is discussed here.

A sample tiling of an irregularly shaped floor space is shown as an example, and applications of the tiling algorithm are indicated by giving verbal sketches of automation systems for a food court, a parking lot, and an airport baggage tracking system that can make use of it.

RFID (Radio Frequency Identification) growth in daily life

identify and track assets: paper and pencil or similar
manual record keeping techniques; bar code techniques
using printed paper or plastic labels with laser readers.
Barcode labels use light beams which cannot read
through dirt, or around corners or through walls, or at
distances significantly greater than six inches. Bar code
was thus limited to clean environments with a direct line
of sight from the reader, and the reader had to be close
to the label. The development of radio frequency
techniques promised to overcome these limitations and
with the introduction of the Radio Frequency
Identification products, this promise became reality. By
this paper we hope to provide an insight into this new
field of wireless technology.

APDL: A Reference XML Schema for Process-centered Definition of RFID Solutions

Indeed, the latter comprise various middleware modules (e.g., data collection and filtering, generation of business events, integration with enterprise applications), which must be deployed and configured independently. In this paper we introduce APDL (AspireRFID Process Description Language), an XML based specification for describing and configuring RFID solutions. Using APDL one can minimize the steps and effort required to integrate and configure an RFID solution, since it unifies all the configuration parameters and steps comprising an RFID deployment. APDL supports several configuration parameters defined in the scope of the EPCglobal architecture and related standards. However, it extends beyond the EPCglobal architecture, to a wider class of RFID solutions. Furthermore, APDL is amendable by visual tools, which obviates the need to carry out low-level programming tasks in order to deploy an RFID solution. These tools are also presented and evaluated in the paper.

The behavior of the algorithm is presented in detail, and its performance is evaluated through a set of simulation experiments. It is demonstrated that the algorithm constitutes an efficient approach to the reader anti-collision problem, especially in dense and lively environments.

potential to simplify and make more robust the tracking of parts or
part carriers through manufacture, storage, distribution and ultimately
the supply chain. RFID control is based on unique RFID transponder tags being attached to parts and used to identify the
part as it moves through the factory or warehouse. Although RFID
dramatically simplifies the process of tracking parts, there are certain
situations that can lead to uncertainty about the true location of
the part. This paper looks at two such situations: a robotic storage stack
and a medicine cabinet. Both cases of uncertainty are successfully
resolved by using a statistical filter. This work may lend itself to
extensions and generalisations using Partially Observable Markov
Decision Process (POMDP) models.

WAL-MART'S USE OF RFID IN GLOBAL SUPPLY CHAIN MANAGEMENT

Just in Time (JIT) ordering enables Wal-Mart to decrease the costs associated with inefficient inventory decisions and handling. Ordering and sales are more closely aligned, decreasing the intensity of Bullwhip effects. Problems associated with RFID, however, include the monetary costs and the ethical questions that are brought up about the technology. Suppliers may be reluctant to spend upwards of $200,000 on necessary software and consumer advocacy groups worry that RFID data could potentially be put to unethical uses. International suppliers may find it even more difficult to justify RFID implementation expenses and global consumers may be even more reluctant to risk privacy violations. A potential solution is for Wal-Mart to share costs with suppliers and work in conjunction with consumer groups globally to ensure proper data security.

Factors affecting RFId adoption in a vertical supply chain: the case of the silk industry in Italy

Despite this rising interest, the diffusion pattern of RFId systems in the vertical SCs has been only scarcely addressed and theoretical contributions explaining dynamics and drivers are still missing. This study shows that the diffusion of innovation theory can be effectively used to explore these questions in a vertical SC. However, three major considerations emerged: (1) the factors influencing, facilitating or inhibiting the adoption process change over time and during the adoption process; (2) facilitators such as business associations play an important role in the SCs composed of small and medium enterprises; and (3) the position of adopters within the SC greatly influences the diffusion process.
