Abstract

Purpose

The purpose of this paper is to acquaint a wide audience of readers with some of the unique remote sensing and navigation capabilities of animals.

Design/methodology/approach

Biomimetic comparison of remote sensors evolved by animals and sensors designed by man. The study and comparison includes thermal infrared sensors used by snakes, echolocation used by bats and dolphins, and navigation methods used by birds. Countermeasures used by prey to avoid capture are also considered.

Findings

Some animals have remote sensing and navigation capabilities that are considerably more efficient than those provided by the human body or designed by man.

Practical implications

Sensor designers may be encouraged to use the biometic approach in the design of new sensors.

Social implications

The paper provides a better understanding of animal behaviour, especially their unique abilities to remotely sense, echolocate and navigate with high accuracy over considerable distances.

Originality/value

The paper presents a comparison of remote sensors used by animals with those developed by humans. Remote sensor designers can learn to improve their sensor designs by studying animal sensors within a biomimetic framework.

This paper aims to review the critical technology development of avian radar system at airports.

Abstract

Purpose

This paper aims to review the critical technology development of avian radar system at airports.

Design/methodology/approach

After the origin of avian radar technology is discussed, the target characteristics of flying birds are analyzed, including the target echo amplitude, flight speed, flight height, trajectory and micro-Doppler. Four typical airport avian radar systems of Merlin, Accipiter, Robin and CAST are introduced. The performance of different modules such as antenna, target detection and tracking, target recognition and classification, analysis of bird information together determines the detection ability of avian radar. The performances and key technologies of the ubiquitous avian radar are summarized and compared with other systems, and their applications, deployment modes, as well as their advantages and disadvantages are introduced and analyzed.

Findings

The ubiquitous avian radar achieves the long-time integration of target echoes, which greatly improves detection and classification ability of the targets of birds or drones, even under strong background clutter at airport. In addition, based on the big data of bird situation accumulated by avian radar, the rules of bird activity around the airport can be mined to guide the bird avoidance work.

Originality/value

This paper presented a novel avian radar system based on ubiquitous digital radar technology. The authors’ experience has confirmed that this system can be effective for airport bird strike prevention and management. In the future, the avian radar system will see continued improvement in both software and hardware, as the system is designed to be easily extensible.

Abstract

Purpose

This paper aims to analyze the contradictions between telecommunications regulation and environmental law in America, via coverage of the problem of large numbers of birds being killed at communications towers.

Design/methodology/approach

Via statutory, legal, and qualitative analysis, this article provides an analysis of Federal Communications Commission (FCC) compliance with environmental statutes and the conflicts that arise between the agency's mandate to maintain a robust telecommunications network and its statutory responsibilities for environmental protection.

Findings

Every year, millions of birds are killed at communications towers. In 1999, the US Fish and Wildlife Service issued guidelines urging the FCC to take action on this problem, as required by various environmental statutes. The FCC ignored the guidelines for several years and defeated the American Bird Conservancy in court when that group sued for observance of the guidelines, but this ruling was later overturned on appeal. The FCC has exhibited a pattern of responding to these developments years after the fact while obfuscating its previous history of non‐compliance and non‐cooperation. As of early 2012 no viable solution to the avian mortality problem has been proposed.

Practical implications

The FCC is required to comply with federal environmental statutes and regulations. However, citizens wishing to dispute FCC environmental compliance will face challenges arising from conflicting statutes and inconsistencies in federal agency behavior.

Originality/value

There has been very little research on the intersection of environmental law and telecommunications regulation, and the particular matter of avian mortality at communications towers has only been analyzed by ornithologists and environmental scientists.

Abstract

Purpose

The purpose of this paper is to develop a novel type of full‐size flight control iron bird based on a passive electronic hydraulic servo loading system.

Design/methodology/approach

On the basis of mathematical modeling of passive loading system math model, the detailed design process of the flight control iron bird is presented. Subsequently, the system digital simulation and physical verification are also given.

Findings

Experimental results show that the proposed approach can reduce the redundant forces and improve the system dynamic and force‐tracking accuracy.

Practical implications

This newly‐developed flight control iron bird system has been successfully applied in the flight control system design of some fighters.

Originality/value

The proposed approach for flight control iron bird is new and significant for the design of fighter flight control systems.

Abstract

Purpose

The purpose of this paper is to review computational techniques that differ from the familiar “von Neumann” or “Turing” model. The review is prompted by an issue of ERCIM News in which a variety of current projects is reviewed, but attention is also given to earlier computational schemes that were important in the development of cybernetic ideas. The early work was aimed at simulation of biological mechanisms, but accepting neurons as complete entities. The current projects now reviewed fall under two headings, one relating to biology, but differing from the earlier studies in giving attention to internal cellular mechanisms. The other heading is quantum computing, which at first sight seems distinct from the first. Attention is drawn to a paper by Ball in 2011that narrows this apparent gap by indicating important connections between quantum physics and biology.

Design/methodology/approach

The aim is to review developments on the internet, especially those of general cybernetic interest.

Findings

The material from the special issue of ERCIM News refers to ongoing research that offers, in the biological context, new computing paradigms with capacity for adaptation and self‐organisation, and in the quantum context super‐fast computing and security.

Practical implications

In addition to the above, two‐way interaction is claimed to give fresh insight into biological mechanisms.

Originality/value

It is hoped this is a valuable periodic review.

Abstract

Purpose

Recent reports based on the sustainable development goals (SDGs) have revealed that no country is in line with achieving the targets of the 2030 Agenda for sustainable development, with the slowest progress being witnessed mainly on goals that are focused on the environment. This study examines environmental performance indicators for assessing the sustainability of building projects.

Design/methodology/approach

The study uses an explanatory sequential design with an initial quantitative instrument phase, followed by a qualitative data collection phase. An extensive critical comparative review of the literature resulted in the identification of ten environmental sustainability indicators. One hundred and sixty-seven questionnaire responses based upon these indicators from the Ghanaian construction industry were received. Data were coded with SPSS v22, analysed descriptively, and via inferential analysis. These data were then validated through semi-structured interviews with six interviewees who are fellows of their respective professional bodies, a senior academic (professor in construction project delivery) and a government official. Data obtained from the semi-structured validation interviews were analysed through the side-by-side comparison of the qualitative data with the quantitative data.

Findings

The findings from the study suggest that all the indicators were important in assessing building projects' environmental sustainability across the entire life cycle. Key among the identified indicators is the effects of the project on “water quality, air quality, energy use and conservation, and environmental compliance and management”. The interviewees further agreed to and confirmed the importance of these identified indicators for assessing the environmental sustainability of building projects in Ghana.

Originality/value

Compared to existing studies, this study adopts the exploratory sequential design to identify and examine the critical indicators in assessing the environmental sustainability across the entire lifecycle of building projects in a typical developing country setting, i.e. Ghana. It reveals areas of prime concern in the drive to place the local construction industry on a trajectory towards achieving environmental sustainability.

Abstract

Observation, either for defence or navigation, has been an objective for man down the centuries. Prehistoric man and medieval lord built settlements and castles on high ground for a clear view of the approaches. At sea, crowsnests were added to masts to aid navigation. Towards the end of the last century armies used manned balloons for battlefield observation. In the First World War aircraft were used for this purpose. With the development of space rockets came satellites, providing man with the ultimate in navigation aid, military observation, telecommunications and meteorlogical observation.

Abstract

Purpose

This paper aims to provide an insight into robot developments that use bioinspired design concepts.

Design/methodology/approach

Following a short introduction to biomimetics, this paper first provides examples of bioinspired terrestrial, aerial and underwater robot navigation techniques. It then discusses bioinspired locomotion and considers a selection of robotic products and developments inspired by snakes, bats, diving birds, fish and dragonflies. Finally, brief concluding comments are drawn.

Findings

The application of design concepts that mimic the capabilities and processes found in living creatures can impart robots with unique abilities. Bioinspired techniques used by insects and other organisms, notably optic flow and sunlight polarisation sensing, allow robots to navigate without the need for methods such as simultaneous localisation and mapping, GPS or inertial measurement units. Bioinspired locomotion techniques have yielded robots capable of operating in water, air and on land and in some cases, making the transition between different media.

Originality/value

This shows how bioinspired design concepts can impart robots with innovative and enhanced navigation and locomotion capabilities.

Abstract

The adaptation of conventional robots to construction sites is fraught with problems. Most significant of these are in relation to positioning, means of collision avoidance, and appropriate navigation strategy. This paper reviews the different levels of navigational autonomy that are possible and describes the system requirements for each. A taxonomy based on the concept of a Mobility Automation Level (MAL) is proposed. Each level is described and the requirements from a robot design perspective are discussed. Finally, a case study, based on an excavator with autonomously optimised movement, known as LUCIE, is used to illustrate some of the design criteria previously described and discussed.
