Item Open Access Conceptualising, Defining and Remodelling Supply Chain Management; An Objective-Oriented Grounded Theory Approach(Cranfield University, 2018-11-15 09:23) Alkebaisi, HussainTechnical paper presented at the 2018 Defence and Security Doctoral Symposium.Although it has been more than three decades since the concept of Supply Chain Management (SCM) was first introduced, there are still significant attempts at, and a call for conceptualising, defining, remodelling and identifying the theory behind it. There is no consensus in the literature on a concise and precise definition of SCM. A rigorous theoretical framework has not yet been developed; the existing models like Supply Chain Operations Reference (SCOR) and the Global Supply Chain Forum (GSCF) models lack the details called for in a holistic model that encompasses the essence of SCM and integrates the best features of the existing models and covers their shortcomings.The argument in the literature is that: “research and practice would be improved if a single definition were adopted” (Mentzer et al., 2001); “closing the gap between SCM theory and actual practice would be the development of a single, unifying SCM framework that both incorporates the best aspects of the existing, widely used frameworks and addresses their current limitations” (Moberg et al., 2008).The literature has shown that most of the research methods and approaches which were used to solve these issues were process-oriented or business functions-oriented (Object-Oriented), that is, the focus was on what firms and organisations are doing, where they do it, or how they do it. However, there is no evidence in the literature that an Objective-Oriented approach has been investigated in resolving those theoretical issues, nor the Grounded Theory research methodology has been applied to that end. Some research papers, for instance, recommended the use of the Grounded Theory research methodology as it could lead to theorising SCM. Therefore, this research focuses on the application of the Grounded Theory research method through an Objective-Oriented line-by-line coding system which will employ multiple data resources including the literature, websites, recorded lectures and recorded interviews.This paper/presentation aims to introduce the gap identified in the literature as reported above to study to what extent the novel approach (Objective-Oriented Grounded Theory Approach) could contribute to resolving the use of a single framework approach that can be applied to multiple sectors. Through this approach, the researcher will be able to: conceptualise SCM, identify the theory behind it, define the concept precisely and concisely and develop a unified model that visualises SCM.Keywords – Supply chain management, Constructivist Grounded Theory, Objective-Oriented approach, Supply chain Management Conceptual Model.ReferencesMentzer, et al.

Water and particulates in fuel may lead to ice formation. The resulting ice formed may eventually block the fuel filters and feed pipes creating safety problems.In order to engineer a lasting solution to the problem of ice in jet fuel it is important to identify precisely the conditions and features that may exacerbate this phenomenon.This work will give a detailed account of the recent advances and technologies in the literature indicating conditions that might lead to the nucleation of water and ice in aircraft fuel systems. It will develop awareness of the key complexities associated with jet fuel chemistry. Furthermore, the work identifies the significant knowledge gaps that exist in the literature highlighting routes to be investigated for future research.Item Open Access Linear Inverse Problem (LIP) Optimisation for Remote Sensing Applications - Spectral Reconstruction(Cranfield University, 2018-11-15 13:26) Chatterjee, Ayan3MT presented at the 2018 Defence and Security Doctoral Symposium.Remote sensing applications like classification and target detection, particularly for high demanded applications such as the detection of difficult targets from cluttered scene, depends on relevant wavelengths of information. While multispectral imagery in airborne or spaceborne platforms consists of a few wavelengths far apart from each other (usually less than 20 bands), which is found not sufficient enough. This project explores new concepts for using not only spatial/spectral information, but also to extract new information from the few bands in the input data for an enhanced spectral mixture analysis.Item Open Access Non-Invasive Determination of Wall Structure and Material Using Synthetic Aperture Radar(Cranfield University, 2018-11-15 17:16) Elgy, James3MT presented at the 2018 Defence and Security Doctoral Symposium.Through-Wall remote sensing has become an area of great interest in both civilian and military sectors, with uses ranging from search and rescue to the assessment of the insulation used in building construction. Low frequency Synthetic Aperture Radar (SAR) is an attractive option due to its long-range, all-weather and non-destructive nature, with different radar modalities each providing useful information. Unfortunately, in a through-wall scenario, radar accuracy is inherently decreased due to the electrical properties of the wall material, leading to defocused and distorted images. Funded in part by Dstl, this research focuses on the remote determination of the thickness and refractive index of walls, through the use of different radar measuring geometries. In addition to providing useful auxiliary information, the knowledge of the wall properties can be used to improve the quality of through-wall SAR imagery and to address some of the fundamental limitations of the technology .
