Abstract

Briefly reviews previous literature by the author before presenting an original 12 step system integration protocol designed to ensure the success of companies or countries in their efforts to develop and market new products. Looks at the issues from different strategic levels such as corporate, international, military and economic. Presents 31 case studies, including the success of Japan in microchips to the failure of Xerox to sell its invention of the Alto personal computer 3 years before Apple: from the success in DNA and Superconductor research to the success of Sunbeam in inventing and marketing food processors: and from the daring invention and production of atomic energy for survival to the successes of sewing machine inventor Howe in co‐operating on patents to compete in markets. Includes 306 questions and answers in order to qualify concepts introduced.

Abstract

Describes how radio telemetry can interface with process control systems such as supervisory control and data acquisition [SCADA] and distributed control systems [DCS] greatly increasing their power and efficiency. Outlines the basis of radio telemetry, the behaviour of electromagnetic waves, frequency and wavelengths. Uses the water industry as an example of the use of a large scale and sophisticated SCADA system to provide date collection and control links over a large area. Concludes that the versatility of radio telemetry coupled with its cost‐effectiveness means that this technology can help to expand and improve communications in an increasing number of industries.

Abstract

Purpose

The purpose of this paper is to investigate the effect on time to complete a task depending on how a human operator interacts with a mobile‐robot. Interaction is investigated using two tele‐operated mobile‐robot systems, three different ways of interacting with robots and several different environments. The speed of a tele‐operator in completing progressively more complicated driving tasks is investigated also.

Design/methodology/approach

Tele‐operators are timed completing a series of tasks using a joystick to control a mobile‐robot. They either watch the robot while operating it, or sit at a computer and view scenes remotely on a screen. Cameras are either mounted on the robot, or so that they view both the environment and robot. Tele‐operators complete tests both with and without sensors. One robot system uses an umbilical cable and one uses a radio link.

Findings

In simple environments, a tele‐operator may perform better without a sensor system to assist them but in more complicated environments then a tele‐operator may perform better with a sensor system to assist. Tele‐operators may also tend to perform better with a radio link than with an umbilical connection. Tele‐operators sometimes perform better with a camera mounted on the robot compared with pre‐mounted cameras observing the environment (but that depends on tasks being performed).

Research limitations/implications

Tele‐operated systems rely heavily on visual feedback and experienced operators. This paper investigates how to make tasks easier.

Practical implications

The paper suggests that the amount of sensor support should be varied depending on circumstances.

Originality/value

Results show that human tele‐operators perform better without the assistance of a sensor systems in simple environments.

Abstract

DESIGN MTBF's under military airborne conditions are up to 10 times greater than those of present operational equipment. Reliability is enhanced through use of all solid‐state design whenever possible, electronic tuning and switching, a high reliability parts programme and application of multilayer and microelectronic circuits. Modular construction and planar functional packaging are employed. All units meet or exceed MIL‐E‐5400, class IX environmental requirements and are made by the Collins Radio Co.

Abstract

Purpose

The purpose of this paper is to investigate the effect of time delay on the ability of a human operator to complete a task with a teleoperated mobile‐robot using two systems, two different ways of interacting with the mobile‐robots and several different environments.

Design/methodology/approach

Teleoperators are observed completing a series of tasks using a joystick to control a mobile‐robot while time delays are introduced to the system. They sit at a computer and view scenes remotely on a screen. Cameras are either mounted on the robot or mounted externally so that they view both the environment and robot. Teleoperators complete the tests both with and without sensors. One robot system uses an umbilical cable and one uses a radio link.

Findings

In simple environments, a teleoperator may perform better without a sensor system to assist them but as time delays are introduced then there are more failures. In more complicated environments or when time delays are longer, then teleoperators perform better with a sensor system to assist. Teleoperators may also tend to perform better with a radio link than with an umbilical connection.

Research limitations/implications

Teleoperated systems rely heavily on visual feedback and experienced operators. This paper investigates the effect of introducing a delay to the delivery of that visual feedback.

Practical implications

The paper suggests that in simple environments with short time delays then the amount of sensor support should be small but in more complicated environments or with longer delays then more sensor support needs to be provided.

Originality/value

Results from imposing time delays on a teleoperated mobile‐robot are presented. Effects on the task of different ways of viewing activity on a computer display are presented, that is with cameras mounted on the robot or cameras mounted externally to view both the environment and robot. Results from using sensors to assist teleoperators are presented. The paper suggests that the amount of sensor support should be varied depending on circumstances.

Abstract

Purpose

The purpose of this paper is to investigate the effect on completion of mobile‐robot tasks depending on how a human tele‐operator interacts with a sensor system and a mobile‐robot.

Design/methodology/approach

Interaction is investigated using two mobile‐robot systems, three different ways of interacting with the robots and several different environments of increasing complexity. In each case, the operation is investigated with and without sensor systems to assist an operator to move a robot through narrower and narrower gaps and in completing progressively more complicated driving tasks. Tele‐operators used a joystick and either watched the robot while operating it, or sat at a computer and viewed scenes remotely on a screen. Cameras are either mounted on the robot to view the space ahead of the robot or mounted remotely so that they viewed both the environment and robot. Every test is compared with sensor systems engaged and with them disconnected.

Findings

A main conclusion is that human tele‐operators perform better without the assistance of sensor systems in simple environments and in those cases it may be better to switch‐off the sensor systems or reduce their effect. In addition, tele‐operators sometimes performed better with a camera mounted on the robot compared with pre‐mounted cameras observing the environment (but that depended on tasks being performed).

Research limitations/implications

Tele‐operators completed tests both with and without sensors. One robot system used an umbilical cable and one used a radio link.

Practical implications

The paper quantifies the difference between tele‐operation control and sensor‐assisted control when a robot passes through narrow passages. This could be an useful information when system designers decide if a system should be tele‐operated, automatic or sensor‐assisted. The paper suggests that in simple environments then the amount of sensor support should be small but in more complicated environments then more sensor support needs to be provided.

Originality/value

The paper investigates the effect of completing mobile‐robot tasks depending on whether a human tele‐operator uses a sensor system or not and how they interact with the sensor system and the mobile‐robot. The paper presents the results from investigations using two mobile‐robot systems, three different ways of interacting with the robots and several different environments of increasing complexity. The change in the ability of a human operator to complete progressively more complicated driving tasks with and without a sensor system is presented and the human tele‐operators performed better without the assistance of sensor systems in simple environments.

Abstract

This chapter examines elements of the regulatory framework in effect in the Brazilian Border Region and neighboring countries as they interact with elements of the culture industry. Located in what is referred to as the Southern Arc, the first city we examine, Foz do Iguaçu-PR, lies on the border between Paraguay and Argentina. The second city is Tabatinga-AM, part of the conurbation region made up by a Colombian city and including the Peruvian border, coming to be known as the Northern Arc.

Our research was produced through the triangulation of primary data obtained in two trips into the field, carried out in 2013 and 2014, secondary data (official and semi-official) and academic bibliography.

Although projects relating to border integration, citizenship and economic development do exist, they do not question or challenge a nationalistic and politicized regime of representation portraying border areas primarily as routes for cocaine traffic or home to terrorist cells. The representation regime disseminated by mainstream media thus reduces the rich color and dynamics of the region to impoverished tones of gray recognizable in terms of “the name of the other.”

This chapter provides a relevant contribution to our understanding of communication processes carried out in two different regions of Brazil, both of them located far from the spotlights of mainstream Brazilian media. We employ a theoretical framework that combines geography of communication with perspectives on communication in borderland regions.
