A critical comparison of approaches to resource name management within the IEC common information model

Copyright @ 2012 IEEEElectricity network resources are frequently identified within different power systems by inhomogeneous names and identities due to the legacy of their administration by different utility business domains. The IEC 61970 Common Information Model (CIM) enables network modeling to reflect the reality of multiple names for unique network resources. However this issue presents a serious challenge to the integrity of a shared CIM repository that has the task of maintaining a resource manifest, linking network resources to master identities, when unique network resources may have multiple names and identities derived from different power system models and other power system applications. The current approach, using CIM 15, is to manage multiple resource names within a singular CIM namespace utilizing the CIM “IdentifiedObject” and “Name” classes. We compare this approach to one using additional namespaces relating to different power systems, similar to the practice used in CIM extensions, in order to more clearly identify the genealogy of a network resource, provide faster model import times and a simpler means of supporting the relationship between multiple resource names and identities and a master resource identity.This study is supported by the UK National Grid and Brunel University

Embedding Requirements within the Model Driven Architecture

The Model Driven Architecture (MDA) brings benefits to software development, among them the potential for connecting software models with the business domain. This paper focuses on the upstream or Computation Independent Model (CIM) phase of the MDA. Our contention is that, whilst there are many models and notations available within the CIM Phase, those that are currently popular and supported by the Object Management Group (OMG), may not be the most useful notations for business analysts nor sufficient to fully support software requirements and specification. Therefore, with specific emphasis on the value of the Business Process Modelling Notation (BPMN) for business analysts, this paper provides an example of a typical CIM approach before describing an approach which incorporates specific requirements techniques. A framework extension to the MDA is then introduced; which embeds requirements and specification within the CIM, thus further enhancing the utility of MDA by providing a more complete method for business analysis

Synchronously-pumped OPO coherent Ising machine: benchmarking and prospects

The coherent Ising machine (CIM) is a network of optical parametric oscillators (OPOs) that solves for the ground state of Ising problems through OPO bifurcation dynamics. Here, we present experimental results comparing the performance of the CIM to quantum annealers (QAs) on two classes of NP-hard optimization problems: ground state calculation of the Sherrington-Kirkpatrick (SK) model and MAX-CUT. While the two machines perform comparably on sparsely-connected problems such as cubic MAX-CUT, on problems with dense connectivity, the QA shows an exponential performance penalty relative to CIMs. We attribute this to the embedding overhead required to map dense problems onto the sparse hardware architecture of the QA, a problem that can be overcome in photonic architectures such as the CIM

An investigation into the effects of computer integrated manufacturing systems in the productivity of SMEs in Pakistan

The current dynamic and turbulent manufacturing environment has forced companies that compete globally to change their traditional methods of conducting business [Producer to consumer]. Recent developments in manufacturing and business operations have lead to the adoption of Computer Integrated Manufacturing (CIM) technologies that are based on systems and processes that support global competitiveness, especially for Small and Medium Enterprises (SMEs). Organizations and SMEs in particular need to re-evaluate every aspect of their manufacturing strategy and quickly move towards a CIM based environment where manufacturing technologies, business strategies and processes are integrated together. This paper highlights the development of a CIM adoption model that has resulted from empirical work generated from SMEs in Pakistan. The model consists of the parameters such as Top Management Support, System Integration, Marketing, and over all performance

I walk to see, I walk to know: Walking to Wongawol. An exhibition and I walk to see, I walk to know: Walking to Wongawol. An exegesis

The context of my embodied project, I Walk to See, I Walk to Know: Walking to Wongawol, is an exploration into 1) the absence of Western Desert Aboriginal narratives via the act of walking as knowing and 2) my recently discovered ancestral connections, which were historically erased by the state. The location of my project is Wongawol Station in the Western Desert, Western Australia, where my Indigenous ancestors lived, and whose lives I draw upon to make connections with the narratives and sensations of the desert landscape. I use the methodology of walking to investigate the interconnectivity between body and space/place and how this might be interpreted in relation to my research. For Nandi Chinna (2014), walking defines the body as the sensory vessel that can experience the dimensions of told and untold narratives of life on earth. I further explore the act of walking through the lens of rhythmanalysis—an approach that refers to how movement is a primary way of “engaging with the world” (Chen, 2013, p. 531). This is illustrated by works such as Raban’s Fergus Walking (Chen, 2013), a structural film that experiments within a nonbinary representation of walking within disrupted notions of time and space. Expanding on this idea, I have incorporated Derrida’s concepts of absence/presence within language/text, time and space as informed by his deconstructionism and nonbinary phenomenology to disrupt accepted literary and philosophical dichotomies. Indigenous film maker Thornton (2018) is also examined from the perspective of cinematography techniques in relation to body, memory, history and the land. Anselm Kiefer’s artworks, which convey the effects of Nazi Germany’s holocaust, allow a potent comparison reflecting “an intimate involvement with destruction and apocalypse [which acts] to provoke and keep memory alive” (Spies, 2016, p. 17). Underpinning my practice-led research are the writings of phenomenologists Merleau- Ponty (1962, 2012) and Heidegger (1962), who believe that the body and the world cannot be separated and that the body is essentially the primary place of knowing and interpreting the world (Merleau-Ponty, 2012): “my existence as subjectivity is identical with my existence as a body and with the existence of the world” (p. 431). The resultant dynamism and potentialities of working with materials to define the place/space of my ancestors comprises the act of walking, field notes, archives, photographic processes, ceramics and print processes. Further, the knowledge gained from acute immersive processes, experiential outcomes in situ and references to government documents characterises this exegesis as preparatory work towards a much larger body of research yet to be undertaken
