Abstract

Purpose

The purpose of this paper is to explore the possible roles of active tails for steady-state legged locomotion, focusing on a design principle which simplifies control by decoupling different control objectives.

Design/methodology/approach

A series of simple models are proposed which capture the dynamics of an idealized running system with an active tail. These models suggest that the overall control problem can be simplified and effectively decoupled via a proper tail design. This design principle is further explored in simulation using trajectory optimization. The results are then validated in hardware using a one degree-of-freedom active tail mounted on the quadruped robot Cheetah-Cub.

Findings

The results of this paper show that an active tail can greatly improve both forward velocity and reduce body-pitch per stride while adding minimal complexity. Further, the results validate the design principle of using long, light tails compared to shorter heavier ones.

Originality/value

This paper builds on previous results, with a new focus on steady-state locomotion and in particular deals directly with stance phase dynamics. A novel design principle for tails is proposed and validated.

Abstract

Gives an account of Norbert Wiener’s works and how they influenced the author. The seminal Cybernetics or Control and Communications in the Animal and Machine introduces the scientific world to the notion of cybernetics and indeed, according to the author, split it down the middle. Goes on to describe Wiener’s other major works and the impact they had not only on the author but also on other writers, researchers and scientists. Concludes with a brief description of how the author helped Wiener to arrange a European trip in 1964.

Abstract

Purpose

The purpose of this paper is to target the problem of awareness of the history of cybernetics as a field with different actors inside and outside cybernetics. It provides a short overview on research and literature during the last two decades and pleads for a multiplicity of historical views.

Design/methodology/approach

Historical research, review of literature.

Findings

While it can be found that there was a growing historical interest in cybernetics, this cannot be claimed for the history of the American Society of Cybernetics (ASC) as an organization and a productive network. One reason seems to be the lack of archival sources. The article provides a proposal to reconstruct such an archive for the history of the ASC.

Originality/value

Stimulation of historical awareness for and in cybernetics.

Abstract

Purpose

Nowadays, to design the information security mechanism for computing and communication systems, there are various approaches available like cryptographic approach, game-theoretic approach, quantitative–qualitative analysis-based approach, cognitive-behavioral approach, digital forensic-based approach and swarm computing-based approach. The contemporary research in these various fields is independent in nature. The purpose of this paper is to investigate the relationship between these various approaches to information security and cybernetics.

Design/methodology/approach

To investigate the relationship between information security mechanisms and cybernetics, Norbert Wiener’s concepts and philosophy of the cybernetics have been used in the present work. For a detailed study, concepts, techniques and philosophy of the cybernetics have been extracted from the books of Norbert Wiener titled “The human use of human beings” and “Cybernetics or control and communication in the animal and the machine”.

Findings

By revisiting the concepts of the cybernetics from the information security perspectives, it has been found that the aspects of information security and the aspects of cybernetics have great bonding.

Originality/value

The present paper demonstrates how bonding between cybernetics and information security can be used to solve some of the complex research challenges in information security area.

Abstract

Over the past eight years, the MELVYL catalog has become one of the largest public access catalogs in the world, and now plays a central role in providing access to the library resources of the University of California. Currently, under heavy load, the MELVYL catalog supports many hundreds of simultaneous terminal connections, servicing over a quarter of a million queries a week and displaying more than two million records a week to its user community. This article discusses the history of the network that has supported the MELVYL catalog from the early days of its prototype to the present. It also describes both the current technical and policy issues that must be addressed as the network moves into the 1990s, and the roles that the network is coming to play in integrating local automation, the union catalog, access to resource databases, and other initiatives. Sidebars discuss the TCP/IP protocol suite, internet protocol gateways, and Telenet and related inter‐operability problems.

Abstract

Although there is great potential for diversity, library and information science (LIS) is a relatively homogenous profession. Increasing the presence of librarians of color may help to improve diversity within LIS. However, recruiting ethnic minorities into LIS has proven to be difficult despite various initiative including scholarships, fellowships, and locally focused programs. The central questions explored in this research can be divided into two parts: (1) Why do ethnic minorities choose librarianship as a profession? (2) What would motivate members of minority groups to join a profession in which they cannot see themselves?

The research was conducted through semi-structured, qualitative interviews of 32 ethnic minority students from one of four ethnic minority groups (African American, Asian American, Hispanic/Latino, and Native American) currently enrolled in an LIS graduate program. Eleven themes emerged from the data: libraries, librarians, library work experience, LIS graduate program, career plans and goals, education and family, support, mentors, ethnicity and community, acculturation, and views of diversity.

The findings seem to support many assumptions regarding expectations and career goals. The findings related to libraries, librarians, mentors, and support illustrate that many recruitment initiatives are starting in the right place. However, the most noteworthy findings were those that centered on identity, acculturation, and diversity because they dealt with issues that are not often considered or discussed by many in the profession outside of ethnic minority organizations.
