Abstract

Purpose

The purpose of this paper is to design a compact, light and relatively inexpensive navigation and guidance system capable of providing the required navigation performance (RNP) in all phases of flight of small unmanned aircrafts (UA), with a special focus on precision approach and landing.

Design/methodology/approach

Two multi-sensor architectures for navigation and guidance of small UA are proposed and compared in this paper. These architectures are based, respectively, on a standard extended Kalman filter (EKF) approach and a more advanced unscented Kalman filter (UKF) approach for data fusion of global navigation satellite systems (GNSS), micro-electro-mechanical system (MEMS)-based inertial measurement unit (IMU) and vision-based navigation (VBN) sensors.

Findings

The EKF-based VBN-IMU-GNSS-aircraft dynamics model (ADM) (VIGA) system and the UKF-based system (VIGA+) performances are compared in a small UA integration scheme (i.e. AEROSONDE UA platform) exploring a representative cross-section of this UA operational flight envelope, including high-dynamics manoeuvres and CAT-I to CAT-III precision approach tasks. The comparison shows that the position and attitude accuracy of the proposed VIGA and VIGA+ systems are compatible with the RNP specified in the various UA flight profiles, including precision approach down to CAT-II.

Originality/value

The novelty aspect is the augmentation by ADM in both architectures to compensate for the MEMS-IMU sensor shortcomings in high-dynamics attitude determination tasks. Additionally, the ADM measurements are pre-filtered by an UKF with the purpose of increasing the ADM attitude solution stability time in the UKF-based system.

Abstract

Purpose

Th purpose of this paper is to represent the role of social capital for the knowledge management system (KMS) in the kind of literature which is related to the topics in the creative industry.

Design/methodology/approach

This paper uses conceptual and literature study with empirical quantitative and qualitative investigation to validate. As some literature states that KMS is an organizational process and tool for acquisition, conversion, application and protection of existing knowledge as a way to use, develop and manage it which comes from internal and external organizations.

Findings

Literature shows that for some organizations, knowledge is gained through research and development (R&D) of the internal organization. In contrast, the creative industry requires knowledge that is derived from social capital such as social environment and community. The social environment and community (social capital) will provide knowledge that is required for the existence of the creative industry in producing the creative product that may represent the social context in which the creative industry exists. This study uses a meta-analysis as a tool of analysis to classify previous research and studies regarding the roles of social capital for KMS in the creative industry that were used as the cornerstone of the research.

Originality/value

Studies in the creative industry previously show that knowledge is a collaboration of tacit knowledge and explicit knowledge which is gained from various the creative classes within the industry. As a renewable resource-based industry, creativity, skill and talent are resources that are used to be commercialized to gain wealth for not only big industries but also for micro, small and medium economies (UMKM) that mostly done by communities, to create employment through the exploitation of intellectual property. Therefore, the creative industry can be meant as a knowledge-based industry that requires the application of KMS in its operation.

Abstract

Purpose

This paper aims to build on Fred Beard’s study of the world’s archives to identity historical advertising and marketing ephemera, published in this journal in 2018, by focussing on resources available in Europe to augment his survey.

Design/methodology/approach

Online searching, supplemented by literature emanating from the business archive sector, led to the identification of 177 repositories or online sites in Europe holding advertising and marketing archives of significance for researchers. These are set out in two accompanying tables.

Findings

A wide diversity of European archives that are open to researchers is revealed in this paper. Many are the archives of the business themselves, but a number of collecting repositories are also listed, brought together for the first time.

Research limitations/implications

This paper focusses solely on Europe but does not claim to be comprehensive, as the study was time-limited and readers will, no doubt, know of resources that the author has missed. The findings relate mostly to Western Europe, so there is scope for further study to encompass archives in the former eastern bloc. Exploration of sources in Africa, Asia and Latin America would further supplement Beard’s original study.

Originality/value

This research brings together the broadest list of advertising and marketing sources open to researchers in Europe published to date. As Beard’s focus was more on the Americas, this examination redresses the balance with an array of European sources which, it is hoped, will contribute to the greater use of many little-known or under-researched resources by researchers across the world.
