The promised land: costs and benefits of the NBN vision
Creators: name: Martin, Ian
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: The substance of the Governments NBN vision has settled on its importance as a productivity driver. Top-down productivity analysis of the NBN appear to be quite strongly positive while bottom-up cost benefit analyses (CBA) seem to be invariably negative. Proposals to build the FTTN version of the NBN were subject to evaluation, which found that none offered value for money. The second iteration of NBN, the FTTP version, was not subject to such an evaluation. Instead an independent CBA by Henry Ergas and Alex Robson in August 2009 suggests that the incremental benefits of the FTTP NBN do not justify the incremental costs. Productivity gains from high speed broadband may have declining marginal benefit and possible gains from the next set of industry developments may be quite different and harder to achieve compared with those achieved on fixed networks over the past 20 years. The lack of CBA on the NBN means that there is an unquantified risk. We consider the Governments inherent desire to off-lay this risk from the federal budget undermines telecommunications policy development, legislation and regulation. We argue such a distortion has the potential to undermine industry development for more than a decade as Government tries to protect a poorly evaluated investment decision, a pattern that has long undermined industry development in Australia.

description: One new cycloartane triterpene glycoside (1) was isolated from the whole plant of Beesia calthaefolia. Its structure was elucidated on the basis of extensive spectroscopic data analysis. Its inhibitory effect was measured by the classical pathway of the complement system, and compared with those of known related cycloartane glycosides 2 and 3, previously isolated by us from the same plant. Compounds 1 and 2 exhibited inhibitory activity of complement system with IC50 of 395.3 and 214 μM, respectively. The results suggested that OH at C-12, C-18 and C-15 along with the polarity could affect the inhibitory activity.

description: Energy-efficient machine learning models that can run directly on edge devices are of great interest in IoT applications, as they can reduce network pressure and response latency, and improve privacy. An effective way to obtain energy-efficiency with small accuracy drops is to sequentially execute a set of increasingly complex models, early-stopping the procedure for "easy" inputs that can be confidently classified by the smallest models. As a stopping criterion, current methods employ a single threshold on the output probabilities produced by each model. In this work, we show that such a criterion is sub-optimal for datasets that include classes of different complexity, and we demonstrate a more general approach based on per-classes thresholds. With experiments on a low-power end-node, we show that our method can significantly reduce the energy consumption compared to the single-threshold approach.

Beyond Network Neutrality: the state of play in Japanese telecommunication competition
Creators: name: Aizu, Izumi

Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: This paper describes the present information and communication technology (ICT) market in Japan and introduces some key policy issues currently impacting on the evolving broadband, mobile, Internet and next generation network market, and other issues likely to impact them in future. The paper argues that there is an implicit guiding principle behind several policy initiatives on these issues that might well be described as being based on the conceptual framework of 'Network Neutrality'. The paper further identifies some new policy issues, such as mobile content regulation, interconnection of the NGN and the Internet (IPv6), the introduction of Internationalised Domain Name (IDN) country code Top-Level Domain (ccTLD), and depletion of IPv4 address spaces. In order to accommodate these new policy challenges located in the upper layer of the communication architecture, this paper suggests extending the scope of Network Neutrality and examining the multi-stakeholder approach exercised at the Internet Governance Forum (IGF).

Collective patterns and stable misunderstandings in networks striving for consensus without a common value system

description: Collective phenomena in systems of interacting agents have helped us understand diverse social, ecological and biological observations. The corresponding explanations are challenged by incorrect information processing. In particular, the models typically assume a shared understanding of signals or a common truth or value system, i.e., an agreement of whether the measurement or perception of information is `right' or `wrong'. It is an open question whether a collective consensus can emerge without these conditions. Here we introduce a model of interacting agents that strive for consensus, however, each with only a subjective perception of the world. Our communication model does not presuppose a definition of right or wrong and the actors can hence not distinguish between correct and incorrect observations. Depending on a single parameter that governs how responsive the agents are to changing their world-view we observe a transition between an unordered phase of individuals that are not able to communicate with each other and a phase of an emerging shared signalling framework. We find that there are two types of convention-aligned clusters: one, where all social actors in the cluster have the same set of conventions, and one, where neighbouring actors have different but compatible conventions (`stable misunderstandings').

Sakurai's Object revisited: new laboratory data for carbonates and melilites suggest the carrier of 6.9 $μ$m excess absorption is a carbonate

description: We present new room-temperature 1100 - 1800 cm^{-1} spectra of melilite silicates and 600 - 2000 cm^{-1} spectra of three randomly orientated fine-grained carbonates to determine the possible carrier(s) of a 6.9~micron absorption feature observed in a variety of dense astronomical environments including young stellar objects and molecular clouds. We focus on the low-mass post-AGB star Sakurai's Object which has been forming substantial quantities of carbonaceous dust since an eruptive event in the 1990s. Large melilite grains cannot be responsible for the 6.9-micron absorption feature because the similarly-shaped feature in the laboratory spectrum was produced by very low (0.1 per cent by mass) carbonate contamination which was not detected at other wavelengths. Due to the high band-strength of the 6.9-micron feature in carbonates, we conclude that carbonates carry the astronomical 6.9~micron feature. Replacement of melilite with carbonates in models of Sakurai's object improves fits to the 6 - 7-micron Spitzer spectra without significantly altering other conclusions of Bowey's previous models except that there is no link between the feature and the abundance of melilite in meteorites. With magnesite (MgCO3), the abundance of 25-micron-sized SiC grains is increased by 10 - 50 per cent and better constrained. The mass of carbonate dust is similar to the mass of PAH dust. Existing experiments suggest carbonates are stable below 700~K, however it is difficult to ascertain the applicability of these experiments to astronomical environments and more studies are required.

description: There has been a lively debate surrounding the Australian Governments plan to build a fibre-based National Broadband Network. Unfortunately, a variety of urban myths about the NBN have evolved and spread over the past 12 months. Some of these myths are based on misunderstandings of the capabilities and limitations of broadband technology and some are out of alignment with experience in countries where broadband access is more advanced than in Australia. The objective of this article is to correct some of these misconceptions, to debunk some of the more common urban myths and to provide some basic facts for the lay person on the capabilities and limitations of various broadband technologies.

description: Access problems in Sweden have led the Swedish government to propose a bill of functional separation well ahead of the parallel process in the European Union. The proposed bill is a framework for imposing functional separation on an operator and does not answer, although implies affirmatively, whether functional separation actually should be imposed in Sweden. A related question is if functional separation could lead to a reduction in and help the removal of sector regulation. Structural measures have been used in general competition law to improve competitive conditions and experience can be drawn from this. Copyright 2008 Ola Bergstrm.

Indigenous culture and communications: can stakeholders build a better telephone service?
Creators: name: Morsillo, Robert
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: This paper explores the corporate and cultural complexities involved in developing a new communications technology solution, called Country Calling, for remote Indigenous community users. The starting point is the persistent very low take-up and maintenance of personal or household telephone services in these communities.A social construction of technology approach is used to review three primary questions.1. How is the current Standard Telephone Service culturally constructed with respect to remote Indigenous communities?2. How are users represented in the technology innovation process?3. How is a new technology solution negotiated between supplier constraints and user demands?It is important to explore these questions, which should allow for the more intelligent design of communications technologies and provide insights into what makes for successful technological innovation within the Australian telecommunications industry.The paper argues that best-practice public participation processes, which prioritise an understanding of the user environment, can provide for the construction of new technologies that will hopefully allow more people in Australia to stay connected.

description: The paper opens with the PMG as provider of a service to the public. Against the backdrop of a more competitive regime, consumer participation in telecommunications develops with the establishment of TACC and CTN, and later, funding for consumer representation by the Government. With two issues the consumer contracts code and mobile premium services issue, the strains on industry self-regulation and existing representations structures are evident. With the establishment of a new peak consumer body ACCAN, and renewed support from Government and the regulator, new understandings of the limits of industry self-regulation may be reached.

description: One new coumarin, 3,5-dihydroxy-7-O-α-L-rhamno pyranosyl-2H-chromen-2-one (1), was isolated from the whole plant of Sarcandra glabra. The structure was elucidated by spectroscopic methods. Our results indicated that 1 significantly inhibit nitric oxide (NO) production in LPS-induced RAW264.7 macrophages. RT-PCR analysis indicated it inhibited iNOS mRNA expression. In addition, Western blot analysis showed that 1 attenuated LPS-induced synthesis of iNOS protein in the macrophages. These results suggest that 1 could be potential anti-inflammatory agent by down-regulating iNOS expression.

description: Under the Australian Constitution, matters relating to communications are a national responsibility. However, until recently, there had been a broad consensus across the political parties about most communications policies, with the major exception of the privatisation of the former incumbent, Telstra.This consensus no longer holds. One of the issues raised by all sides in the recent election period was broadband, and there is no doubt that, now the election results are clear, Australia may actually be on the way to developing a broadband policy.This article reviews the background to the recent policy debate, and provides some comment on the issues that have been raised in the Election Campaign.

description: The rich body of physical theories defines the foundation of our understanding of the world. Its mathematical formulation is based on classical Aristotelian (binary) logic. In the philosophy of science the ambiguities, paradoxes, and the possibility of subjective interpretations of facts have challenged binary logic, leading, among other developments, to Gotthard Günther's theory of polycontexturality (often also termed 'transclassical logic'). Günther's theory explains how observers with subjective perception can become aware of their own subjectivity and provides means to describe contradicting or even paradox observations in a logically sound formalism. Here we summarize the formalism behind Günther's theory and apply it to two well-known examples from physics where different observers operate in distinct and only locally valid logical systems. Using polycontextural logic we show how the emerging awareness of these limitations of logical systems entails the design of mathematical transformations, which then become an integral part of the theory. In our view, this approach offers a novel perspective on the structure of physical theories and, at the same time, emphasizes the relevance of the theory of polycontexturality in modern sciences.

Liability of ISPs for end-user copyright infringements: the first instance decision in Roadshow Films Pty Ltd v iiNet Ltd (No 3)
Creators: name: Lindsay, David

description: In Roadshow Films Pty Ltd v iiNet [2010] FCA 24, Cowdroy J held that the ISP, iiNet, was not liable for authorising infringements of copyright committed by its subscribers downloading films by means of the BitTorrent peer-to-peer (P2P) system. This article critically analyses the decision of the trial judge, which is now on appeal to the full federal court, pointing out that key aspects of the reasoning are contrary to established law on authorisation liability, as well as to the text of the Copyright Act. As the article explains, while there are good grounds for an appeal, the outcome in the appeal court is far from certain. The article also examines the extent to which an ISP should be held liable for the infringing activities of its subscribers, concluding that this is a complex issue best dealt with by the legislature. If ISPs are to be given greater responsibility for the infringing activities of their subscribers, there may be a need for procedural safeguards to protect against unjust suspensions or terminations of subscriber accounts. In any case, the existing law on the indirect liability of Internet intermediaries, such as ISPs, is manifestly inadequate, and requires reform. Copyright 2010 David Lindsay.

description: This paper reviews the way that participatory media practices have been adopted by cultural institutions such as the Australian Broadcasting Corporation(ABC). A critique of the ABC's adoption of participatory media in relation to its strategy, positioning and charter is used to suggest that a clear framework for a distinctly public form of participatory media is required. By looking at the ABC's experimental social media site Pool, as an example of both the possibilities and challenges for the ABC, it is possible to start to define such a distinctly public form of participatory media.

description: Exploring the intersection of qualitative data analysis and generative artificial intelligence (AI), this presentation considers the current evolving landscape in qualitative software. Tracing the historical evolution of autocoding features in tools like NVivo and ATLAS.ti, the discussion expands to the these tools’ integration of OpenAI's GPT models. It considers novel applications beyond traditional sentiment and 'topic' identification for faster, hopefully robust, insights into qualitative data. Going beyond technical aspects, the session also addresses critical methodological considerations, examining the epistemological and theoretical challenges qualitative scholars face when considering removing the “close” from close reading in qualitative inference.
High-T$_c$ cuprates: a story of two electron subsystems

description: A review of the phenomenology and microscopy of cuprate superconductors is presented, with particular attention to universal conductance features, which reveal the existence of two electronic subsystems. The overall electronic system consists of $1+p$ charges, where $p$ is the doping. At low dopings exactly one hole is localized per planar copper-oxygen unit, while upon increasing doping and temperature, the hole is gradually delocalized and becomes itinerant. Remarkably, the itinerant holes exhibit identical Fermi-liquid character across the cuprate phase diagram. This universality enables a simple count of carrier density and yields comprehensive understanding of the key features in the normal and superconducting state. A possible superconducting mechanism is presented, compatible with the key experimental facts. The base of this mechanism is the interaction of fast Fermi-liquid carriers with localized holes. A change in the microscopic nature of chemical bonding in the copper-oxide planes, from ionic to covalent, is invoked to explain the phase diagram of these fascinating compounds.

description: Global efforts to address climate change increasingly focus on risk communication to encourage people's mitigation behaviour. This study investigates how risk communication influences evacuation behaviour, through repeated risk communications and stated preference surveys. In modelling the learning process of infrequent events like disasters, it is necessary to consider decision-making under uncertainty about future situations and the tendency to forget acquired information. We propose a recursive model that captures two decision dynamics relevant to infrequent events: proactive decision-making amid dynamically changing conditions and the learning and forgetting processes between events. The former is modelled using the recursive logit model on a time-expanded network, while the latter is represented by dynamic changes in utility and memory decay parameters. The estimation results indicate that risk communication generally promotes earlier evacuation to safer places. However, effective communication strategies and the duration of their effects differ based on individuals' perceived and actual risks.

description: The increment in GreenHouse Gases (GHGs) promotes high Global Warming Potential (GWP) due to the production and consumption of hydrofluorocarbons (HFCs) that diverts the aim toward the recycling and reclaiming of refrigerant gases. However, the presence of azeotrope in refrigerant mixtures restricts the recycling process. Therefore, in this work, the refrigerant R410A and R508B have been separated through the hybrid extractive distillation method by using [HMIM][TF2N] and [BMIM][BF4] as a solvent in ASPEN Plus. UNIFAC model has been used for the correlation of ionic liquid in ASPEN Plus. For thermodynamic properties, Cosmotherm has been used with the collaboration of TurbromoleX. The Vapor-liquid Equilibrium (VLE) data has been predicted by using the UNIFAC group contribution method. The Total Annual Cost (TAC) analysis with optimization has been performed. Besides that, the energy analysis has also been performed. In the overall separation process and (TAC) analysis, [BMIM][BF4] proves to be more efficient with high separation efficiency and minimal TAC requirements. Whereas, [HMIM][TF2N]/R508B provides less CO2 emission.

description: The paper analyzes the results of the introduction of the distance learning form (DLF) using electronic educational resources (EER) and the teacher's virtual classroom in primary school. The experiment took place within the framework of the "Smart Kids" All-Ukrainian project during the long quarantine caused by the COVID-19 pandemic. The educational process took place both synchronously and asynchronously. The present paper substantiates the model of organization of distance learning of primary school students using EER and outlines its three main components: the organization of learning, conducting online classes (explaining new material or practicing skills by students) and monitoring the quality of students' independent performance of tasks. The results of the experiment prove that it is necessary to provide teachers and students with computer equipment, Internet access, digital resources for teaching and assessment to implement DLF. It has been established that EER in distance learning can be used both on a regular basis - in each class, and periodically - to explain new material or train skills, the quality of tasks performed by students can be monitored in the virtual office of the teacher and shape an individual trajectory of students' development. The teachers identified the following main problems of DLF implementation: internet interruptions, problems with providing new computer equipment to students and some teachers; lack of state aid in providing EER to all participants in the educational process; limited access to students' computers during complete isolation due to online work of parents. Despite the outlined problems, the quality of distance learning of primary school students during the pandemic using EER was positively and highly assessed by teachers.

description: Objective: Lane changes with the intention to overtake the vehicle in front are especially challenging scenarios for forward collision warning (FCW) designs. These overtaking maneuvers can occur at high relative vehicle speeds and often involve no brake and/or turn signal application. Therefore, overtaking presents the potential of erroneously triggering the FCW. A better understanding of driver behavior during lane change events can improve designs of this human–machine interface and increase driver acceptance of FCW. The objective of this study was to aid FCW design by characterizing driver behavior during lane change events using naturalistic driving study data.Methods: The analysis was based on data from the 100-Car Naturalistic Driving Study, collected by the Virginia Tech Transportation Institute. The 100-Car study contains approximately 1.2 million vehicle miles of driving and 43,000 h of data collected from 108 primary drivers. In order to identify overtaking maneuvers from a large sample of driving data, an algorithm to automatically identify overtaking events was developed. The lead vehicle and minimum time to collision (TTC) at the start of lane change events was identified using radar processing techniques developed in a previous study. The lane change identification algorithm was validated against video analysis, which manually identified 1,425 lane change events from approximately 126 full trips.Results: Forty-five drivers with valid time series data were selected from the 100-Car study. From the sample of drivers, our algorithm identified 326,238 lane change events. A total of 90,639 lane change events were found to involve a closing lead vehicle. Lane change events were evenly distributed between left side and right side lane changes. The characterization of lane change frequency and minimum TTC was divided into 10 mph speed bins for vehicle travel speeds between 10 and 90 mph. For all lane change events with a closing lead vehicle, the results showed that drivers change lanes most frequently in the 40–50 mph speed range. Minimum TTC was found to increase with travel speed. The variability in minimum TTC between drivers also increased with travel speed.Conclusions: This study developed and validated an algorithm to detect lane change events in the 100-Car Naturalistic Driving Study and characterized lane change events in the database. The characterization of driver behavior in lane change events showed that driver lane change frequency and minimum TTC vary with travel speed. The characterization of overtaking maneuvers from this study will aid in improving the overall effectiveness of FCW systems by providing active safety system designers with further understanding of driver action in overtaking maneuvers, thereby increasing system warning accuracy, reducing erroneous warnings, and improving driver acceptance.

description: Against the backdrop of the Rudd government's 2007 election promise for a national wholesale broadband network to be operated under open access principles, this paper explores how the debate in the United States of America for 'open access' fell by the wayside by 2002/03 and was replaced by strident calls for 'network neutrality'. It analyses why this change of emphasis arose and how the opposing sides in the debate have taken network neutrality to mean whatever supports their case. The paper discusses possible lessons impacting on the evolving debate in Australia over the most appropriate regulatory regime underpinning the government's 2009 vision for this national wholesale broadband network to now be state-controlled.

description: A series of novel 3-substituted amino-4-hydroxycoumarin derivatives have been designed and synthesized as chitin synthase (CHS) inhibitors. All the synthesized compounds have been screened for their CHS inhibition activity and antimicrobial activity in vitro. The enzymatic assay indicated that most of the compounds have good inhibitory activity against CHS, in which compound 6o with IC50 of 0.10 mmol/L had stronger activity than that of polyoxins B, which acts as control drug with IC50 of 0.18 mmol/L. As far as the antifungal activity is concerned, most of the compounds possessed moderate to excellent activity against some representative pathogenic fungi. Especially, compound 6b was found to be the most potent agent against Cryptococcus neoformans with minimal inhibitory concentration (MIC) of 4 μg/mL. Moreover, the results of antibacterial screening showed that these compounds have negligible actions to some tested bacteria. Therefore, these compounds would be promising to develop selective antifungal agents.

description: Advances in mobile access broadband technology have a high potential to improve environmental sustainability both directly by enabling novel network deployment concepts and indirectly by changing the way people live and work. In this paper, improvements of the network topology enabled by ubiquitous broadband access are investigated. It is shown that a joint deployment of macro- and publicly accessible residential picocells can reduce the total energy consumption by up to 70% in urban areas. In addition the high potential of indirect effects of improving telecommunication networks, such as enabling teleworking and replacing business travel through video conferencing, is demonstrated and compared with the direct effects.

description: Distributed electricity generation has the potential to deliver sustainability benefits through dramatically increasing energy efficiency, as well as through encouraging the adoption of renewables. It is not without its problems however: two of the largest are the limited utility of the small amounts of power generated, and the lack of economic incentive to invest in small generators.This work discusses an electricity market, using broadband communications as its information infrastructure, specifically designed to make electricity generated by households and offices an attractive source of revenue and a viable source of power.

description: Most existing multi-document machine reading comprehension models mainly focus on understanding the interactions between the input question and documents, but ignore following two kinds of understandings. First, to understand the semantic meaning of words in the input question and documents from the perspective of each other. Second, to understand the supporting cues for a correct answer from the perspective of intra-document and inter-documents. Ignoring these two kinds of important understandings would make the models oversee some important information that may be helpful for inding correct answers. To overcome this deiciency, we propose a deep understanding based model for multi-document machine reading comprehension. It has three cascaded deep understanding modules which are designed to understand the accurate semantic meaning of words, the interactions between the input question and documents, and the supporting cues for the correct answer. We evaluate our model on two large scale benchmark datasets, namely TriviaQA Web and DuReader. Extensive experiments show that our model achieves state-of-the-art results on both datasets.

description: Developers frequently use APIs to implement certain functionalities, such as parsing Excel Files, reading and writing text files line by line, etc. Developers can greatly benefit from automatic API usage sequence generation based on natural language queries for building applications in a faster and cleaner manner. Existing approaches utilize information retrieval models to search for matching API sequences given a query or use RNN-based encoder-decoder to generate API sequences. As it stands, the first approach treats queries and API names as bags of words. It lacks deep comprehension of the semantics of the queries. The latter approach adapts a neural language model to encode a user query into a fixed-length context vector and generate API sequences from the context vector. We want to understand the effectiveness of recent Pre-trained Transformer based Models (PTMs) for the API learning task. These PTMs are trained on large natural language corpora in an unsupervised manner to retain contextual knowledge about the language and have found success in solving similar Natural Language Processing (NLP) problems. However, the applicability of PTMs has not yet been explored for the API sequence generation task. We use a dataset that contains 7 million annotations collected from GitHub to evaluate the PTMs empirically. This dataset was also used to assess previous approaches. Based on our results, PTMs generate more accurate API sequences and outperform other related methods by around 11%. We have also identified two different tokenization approaches that can contribute to a significant boost in PTMs' performance for the API sequence generation task.

description: In this study, an innovative hybrid process was proposed and examined as an alternative for nickel/cobalt separation from a synthetic pregnant leach solution. The first step was carried out by employing electrodeionization of a feed solution containing 950 ppm of nickel and 100 ppm of cobalt after adding EDTA to form (Ni-EDTA)−2 complex to suppress migration of nickel cations toward cathodic compartment. This process increased nickel percentage from 90.47 to 97 in the diluted feed solution. This solution was then subjected to cation exchanging process to adsorb the remaining cobalt cations, leading to a nickel purity of 99.7 wt% with an overall recovery 71.1%. On the other hand, the cathode rinse solution of EDI process which contained a major portion of the cobalt cations underwent three stages of extraction process using cyanex 272, resulting in recovery of 65.5 wt% of cobalt with a purity of 100%. It was seen that six stages of solvent extraction process were needed to reach the same purity of cobalt cations by the traditional extraction method. These findings highlight the superior performance of the proposed hybrid process, which not only yielded a relatively high recovery ratio but also ensured excellent purity of nickel and cobalt.

description: Frequent power failures can introduce significant packet losses during communication among energy harvesting batteryless wireless sensors. Nodes should be aware of the energy level of their neighbors to guarantee the success of communication and avoid wasting energy. This paper presents TRAP (TRAnsiently-powered Protocol) that allows nodes to communicate only if the energy availability on both sides of the communication channel is sufficient before packet transmission. TRAP relies on a novel modulator circuit, which operates without microcontroller intervention and transmits the energy status almost for free over the radiofrequency backscatter channel. Our experimental results showed that TRAP avoids failed transmissions introduced by the power failures and ensures reliable intermittent communication among batteryless sensors.
