Abstract

THE eleventh annual meeting of the Institute was for the first time held simultaneously in three centres—in New York City at Columbia University, in Detroit at Rackham Educational Memorial, and in Los Angeles at the University of Southern California—from January 25 to 29. The purpose of the three simultaneous meetings was to minimize travel by executives and engineers from important war jobs in the present emergency. The same programme was offered at all three centres, papers being sometimes presented by proxies—experts in the same field as far as possible. In spite of the fact that attendance was divided between three centres, there was splendid representation at each place and a wide range of subjects was covered in the many papers. Naturally these were restricted more to analysis, and technology and information as to the latest design or production features of current aircraft or engines was withheld. The same ban applied to striking developments in accessories, instruments and armaments. All papers had to be approved by the Army or Navy and to be read substantially as written. While off‐the‐record discussions were permitted, these discussions were not made public. In particular there was a ban on comparisons between foreign and American materials, equipment or methods. The formula for control of comparison performance stated that the manufacturer's smooth curve calibrations and performance figures might be quoted, but no Wright field performance figures or data could be revealed. In spite of such restrictions a tremendous amount of valuable technical information was presented to the assembled engineers.

Abstract

Purpose – The purpose of this research is to design and build a wild animal pest repellent device with combination of passive infrared (PIR) sensor and ultrasonic signal based on microcontroller as system controller. The PIR sensor is used to detect the presence of wild animal objects and ultrasonic signals to interfere with the hearing.

Design/Methodology/Approach – The design of the system is built based on microcontroller as the system controller. The system as a whole includes hardware and software. The design of hardware consists of the system design on the transmitter side and the system design on the receiver side, while the software in the of system are algorithms using C language programming.

Findings – The resulting repellent device can detect animals approaching up to a distance of 5 m and may interfere with its hearing with a 40 kHz ultrasonic frequency up to a distance of 20 m. The system also uses remote monitoring devices using 433 MHz radio frequency up to a distance of 60 m.

Research Limitations/Implications – Each animal has different hearing frequencies, as well as some wild animals, but the hearing frequencies of wild animals are generally at ultrasonic frequencies. The frequency of animal hearing may vary from audio frequency to ultrasonic frequency, so ultrasonic wave emission testing with varying frequencies is required.

Practical Implications – This research combines systems on transmitters and receivers, with real-time monitoring of wild animal positions, and it can be possible to monitor the position of more detailed animals by installing more types of sensors as well as increasing the number of sensors.

Originality/Value – This paper may provide additional insight into the hearing frequencies of animals and may also serve as comparable papers for similar studies.

Abstract

Purpose

To provide practitioners of management a sense of the importance of strategically leveraging the current and historic development of radio frequency identification (RFID) in order to find inexpensive applications of radio frequency‐based (RF) technologies in many areas.

Design/methodology/approach

A review of the applied literature on RFID, as well as from practical experience, resulted in a basic model of viewpoint to understand the nature of the emergent RF‐based industry.

Findings

Wal‐Mart and other cost sensitive and value chain progressive companies' usage of RFID‐based technology should revolutionize the method that companies' track inventory. However, some of the disadvantages include costs, training, product label and supplies, and privacy infringement. One asset to companies like Wal‐Mart is pallet tracking because it improves on‐time inventory delivery. This helps Wal‐Mart since they rely on just‐in‐time ordering.

Research limitations/implications

RFID is currently used in many industries such as transportation and distribution, manufacturing and processing, and security and law enforcement. The advantages RFID gives to companies are the following: enhanced record management, customer behavior patterns, and accurate inventory tracking.

Practical implications

This paper describes RFID and its implementation process in an academic manner, some disadvantages of RFID, and examples of how the technology can improve customer relationship management (CRM) are discussed. Originality/value – This form of identification can be used in large stores like Wal‐Mart to receive real time information. By implementing RFID, companies will create a fully integrated supply chain system. Traditionally, many supply chain management (SCM) research has simply viewed RF‐based technology as a technological innovation, not a transformational event as this paper presents.

Abstract

Purpose

The available literature suggest that the research on radio frequency identification (RFID)-related issues is largely concentrated on technical, organizational and implementation aspects, and comparatively lesser attention has been invested in understanding the use aspect of such library management systems. The purpose of this paper is to gain an understanding into the factors that influence the use of RFID systems in the library context by empirically testing the relevant constructs from the extended technology acceptance model (TAM).

Design/methodology/approach

A questionnaire-based survey approach was employed for collecting the relevant data from 197 respondents. The respondents were the active users of a RFID-based library system.

Findings

Findings from this study suggested that perceived usefulness and system quality positively influence the user attitude, and user attitude and system quality significantly influence the use of the RFID services. The paper concludes with outlining the salient points, limitations, and future research directions.

Originality/value

The paper evaluates the role of a set of innovation attributes on the acceptance of RFID integrated systems in libraries. Owing to the scant literature availability in empirical investigations on adoption of RFID systems in libraries, the findings from this paper add value to the existing literature in this field, and also to the literature on the TAM model, with the empirical findings being of use to the aspirant libraries looking toward integrating RFID enabled systems.

Abstract

Provides an examination of the importance of barter in the radio industry based on a systematic random sample of 195 radio stations within the continental USA. Describes how data were collected to assess the prevalence of barter in the industry. Analyzes the managerial decisions pertaining to barter to provide basic understanding of barter programming and its role in the station manager’s strategic planning. Concludes that station managers are using barter more and more to reinforce their product offerings and reduce the squeeze on cash flow. Providing programming that hits the right people continues to be a challenge for station managers.
