title: Modular synthesis of discrete controllers

authors: Malik, Petra

abstract: This paper presents supervisory control theory in a process-algebraic setting, and proposes a way of synthesising modular supervisors that guarantee nonblocking. The framework used includes the possibility of hiding actions which results in nondeterminism. As modularity crucially depends on the process equivalence used, the paper studies possible equivalences and points out that, in order to be consistent with respect to the nonblocking property and to supervisor synthesis, a conflict-preserving equivalence must be used. It applies the results to synthesise nonblocking modular supervisors for a manufacturing system.

title: Estimation of fungal biomass and lipid production by morphological characteristics of Mucor rouxii

authors: Fu, Chun-Chong

subjects: image analysis

abstract: This study presents methodology for estimating biomass and lipid production by Mucor rouxii via image analysis. Morphological variations in M. rouxii in relation to its biomass and lipid production were investigated using image analysis. Two parameters were used to characterize fungal morphology: fungal area per unit volume of the culture broth (Af; cm2/ml) and fungal pellet circularity skewing (SK). These two parameters were correlated with both fungal biomass and lipid production and were used to develop an empirical model. This empirical model was further applied to estimate biomass yield and lipid production by M. rouxii under diverse culture conditions. Model predictions for fungal biomass and lipid production were in agreement with experimental results, indicating the reliability of image-based methodology. Thus, image-based methodology can be used to estimate fungal biomass and lipid production.

title: Indigenous Peoples and the State - International Perspectives on the Treaty of Waitangi [Book Review]

authors: Te Aho, Linda

abstract: Just over thirty years ago, in the High Court decision Huakina Development Trust v Waikato Valley Authority, Justice Chilwell famously stated: “There can be no doubt that the Treaty is part of the fabric of New Zealand society.” ¹ At a symposium celebrating 30 years of the Huakina decision, Tom Bennion described the judgment as “a marker, a significant new structure sticking out in the legal landscape, indicating the shape of arguments to come.” This collection of work brings together a range of arguments for our time concerning the meaning and importance of the Treaty of Waitangi, shaped by different perspectives on its context and history.
