Localising urbanism

<p>This research began as a personal dissatisfaction with how the notion of indeterminacy very commonly gets used in contemporary landscape architectural design discourse and practice, most strongly associated with but not limited to what gets termed ‘landscape urbanism’. The dominant use of this notion is associated with design preoccupations such as change over time, bodily movement, the inability to predict, allowing for change and ecological growth or succession - and uses of representation related to these ideas. Peter Connolly has termed this conception the ‘abstract’ notion of indeterminacy. This notion was inspired by the writings of Deleuze and Guattari, however Connolly’s examination of the literature, and my field studies and design investigations point to an alternative version, a ‘concrete’ notion of indeterminacy¹ as being more relevant to designers. The abstract version will only ever be indirectly relevant to the human involvement in landscape. The ‘concrete’ is affectual and intensive and is directly relevant to human spatiality and life. Instead of change in space or over time, the concrete version is, in contrast, about the liveliness and shiftiness of affect (the shiftiness of affects / affordances, / propensities / capabilities…)—the shiftiness of powers. This research attempts to move beyond the attractive ambiguity and confusion associated with the abstract version and engage with the concrete ‘indeterminacy-of-affect’ by focusing on a very restricted realm of small urban spaces, which might be considered incidental spaces, in Wellington city. Through this intentionally limited attempt to directly engage with concrete indeterminacy there emerged, a way to engage with a type of localness associated with these spaces. This process has involved the development of aesthetic and representational techniques and it is suggested that this work is not just relevant to the question of indeterminacy and the local, but is very relevant to the newly emergent interest by landscape architects in design aesthetics².</p>

Eigenvalue bounds for non-selfadjoint Dirac operators

We prove that the eigenvalues of the n-dimensional massive Dirac operator $${\mathscr {D}}_0 + V$$ D 0 + V , $$n\ge 2$$ n ≥ 2 , perturbed by a potential V, possibly non-Hermitian, are contained in the union of two disjoint disks of the complex plane, provided V is sufficiently small with respect to the mixed norms $$L^1_{x_j} L^\infty _{{\widehat{x}}_j}$$ L x j 1 L x ^ j ∞ , for $$j\in \{1,\dots ,n\}$$ j ∈ { 1 , ⋯ , n } . In the massless case, we prove instead that the discrete spectrum is empty under the same smallness assumption on V, and in particular the spectrum coincides with the spectrum of the unperturbed operator: $$\sigma ({\mathscr {D}}_0+V)=\sigma ({\mathscr {D}}_0)={\mathbb {R}}$$ σ ( D 0 + V ) = σ ( D 0 ) = R . The main tools used are an abstract version of the Birman–Schwinger principle, which allows in particular to control embedded eigenvalues, and suitable resolvent estimates for the Schrödinger operator.

ABSTRACT KOROVKIN THEOREMS VIA RELATIVE MODULAR CONVERGENCE FOR DOUBLE SEQUENCES OF LINEAR OPERATORS

We will obtain an abstract version of the Korovkin type approximation theorems with respect to the concept of statistical relative convergence in modular spaces for double sequences of positive linear operators. We will give an application showing that our results are stronger than classical ones. We will also study an extension to non-positive operators.

Extractive and Abstractive Text Summarization Techniques

Text summarization generates an abstract version of information on a particular topic from various sources without modifying its originality. It is essential to dig information from the large repository of data, thereby eliminating the irrelevant information. The manual summarization consumes a large amount of time and hence an automated text summarization model is required. The summarization can be performed from a single source or multiple sources. The Natural Language Processing (NLP) based text summarization can be generally categorized as abstractive and extractive methods. The extractive methods mine the essential text from the document whereas the abstractive methods summarize the document by rewriting. The extractive summarization methods rely on topics and centrality of the document. The abstractive techniques transform the sentences based on the language resources available. This paper deals with the study of extractive as well as abstractive strategies in text summarization. Overall objective of this paper is to provide a significant direction to the researchers to learn about different strategies applied in text summarization.

MAPF Scenario: Software for Evaluating MAPF Plans on Real Robots

Multi-Agent Path Finding (MAPF) deals with finding collision free paths for a set of agents (robots) moving on a graph. The interest in MAPF in the research community started to increase recently partly due to practical applications in areas such as warehousing and computer games. However, the academic community focuses mostly on solving the abstract version of the problem (moving of agents on the graph) with only a few results on real robots. The presented software MAPF Scenario provides a tool for specifying MAPF problems on grid maps, solving the problems using various abstractions (for example, assuming rotation actions or not), simulating execution of plans, and translating the abstract plans to control programs for small robots Ozobots. The tool is intended as a research platform for evaluating abstract MAPF plans on real robots and as an educational and demonstration tool bridging the areas of artificial intelligence and robotics.

Cyber Security Techniques for Internet of Things (IoT)

The purpose of the cyber security policy is to provide guidelines on how to secure public and private resources from cyberattacks. IoT devices are having challenges managing the personal information they collect and helps to people understand that information is managed by a system. Digital twins enhance development by allowing developers to directly manipulate the device's abstract version using programming instructions. It is required to think about possible attack vectors when tuning cyber security for the IoT environment concerns. So, a security administrator is required to think the about possible vulnerabilities of the environment. Supervision and protocols must also be developed for suppliers, manufacturers, vendors, etc. The deployment of consumer understanding to make best use of “smart” strategy, using their own “smart” minds is required. There is a need for a framework or other types of guidance for assessing IoT cyber security to provide an informed approach to securing devices and the ecosystems in which they are set up.

DE ZOLT’S POSTULATE: AN ABSTRACT APPROACH

A theory of magnitudes involves criteria for their equivalence, comparison and addition. In this article we examine these aspects from an abstract viewpoint, by focusing on the so-called De Zolt’s postulate in the theory of equivalence of plane polygons (“If a polygon is divided into polygonal parts in any given way, then the union of all but one of these parts is not equivalent to the given polygon”). We formulate an abstract version of this postulate and derive it from some selected principles for magnitudes. We also formulate and derive an abstract version of Euclid’s Common Notion 5 (“The whole is greater than the part”), and analyze its logical relation to the former proposition. These results prove to be relevant for the clarification of some key conceptual aspects of Hilbert’s proof of De Zolt’s postulate, in his classical Foundations of Geometry (1899). Furthermore, our abstract treatment of this central proposition provides interesting insights for the development of a well-behaved theory of compatible magnitudes.

DENSITY, SMITAL PROPERTY AND QUASICONTINUITY

Based on the abstract version of the Smital property, we introduce an operator$DS$. We use it to characterise the class of semitopological abelian groups, for which addition is a quasicontinuous operation.
