description: The ACM A.M. Turing Award is commonly acknowledged as the highest distinction in the realm of computer science. Since 1960s, it has been awarded to computer scientists who made outstanding contributions. The significance of this award is far-reaching to the laureates as well as their research teams. However, unlike the Nobel Prize that has been extensively investigated, little research has been done to explore this most important award. To this end, we propose the Turing Number (TN) index to measure how far a specific scholar is to this award. Inspired by previous works on Erdos Number and Bacon Number, this index is defined as the shortest path between a given scholar to any Turing Award Laureate. Experimental results suggest that TN can reflect the closeness of collaboration between scholars and Turing Award Laureates. With the correlation analysis between TN and metrics from the bibliometric-level and network-level, we demonstrate that TN has the potential of reflecting a scholar's academic influence and reputation.

description: We give a spinorial characterization of isometrically immersed surfaces into 3-dimensional homogeneous manifolds with 4-dimensional isometry group in terms of the existence of a particular spinor, called generalized Killing spinor. This generalizes results by T. Friedrich for $\R^3$ and B. Morel for $\Ss^3$ and $\HH^3$. The main argument is the interpretation of the energy-momentum tensor of a genralized Killing spinor as the second fondamental form up to a tensor depending on the structure of the ambient space

description: We investigate the behaviour of randomly cross-linked (co)polymer blends using a combination of replica theory and large-scale molecular dynamics simulations. In particular, we derive the analogue of the random phase approximation for systems with quenched disorder and show how the required correlation functions can be calculated efficiently. By post-processing simulation data for homopolymer networks we are able to describe neutron scattering measurements in heterogeneous systems without resorting to microscopic detail and otherwise unphysical assumptions. We obtain structure function data which illustrate the expected microphase separation and contain system-specific information relating to the intrinsic length scales of our networks.

This paper proposes a complete equivalent model approach for the real-time simulation of a hybrid 3-level and modular multilevel converter.
Real-time simulation is a crucial but complicated task for fast control prototyping of high-power converters. Detailed semiconductor device-based model simulates a large number of switching events at a small time step, which requires large computational effort and is thus challenging for real-time simulation. This paper proposes a complete equivalent model (CEM) approach for the real-time simulation of a hybrid 3-level and modular multilevel converter (H3LC). The presented CEM simplifies the detailed equivalent model (DEM) of the H3LC and facilitates the implementation of real-time simulation. A central processing unit (CPU) and field-programmable gate array (FPGA) based simulation is presented whereby the massive parallel computing power of the FPGA enables the simulation of the H3LC's three-level T-type converter and the hundreds of series-connected full-bridge submodules. The rest of the converter system, including the converter controls, the AC grid, and the measurement of the AC currents are implemented within the CPU model. The FPGA-based converter model is interfaced with the CPU model using controlled voltage sources to represent the AC- and DC-side equivalent voltages of the H3LC. The OP5700 real-time digital simulator from OPAL-RT Technologies is used to realize the CPU-FPGA real-time simulation, which is verified by the offline MATLAB/Simulink Simscape model.

In This Issue - How the Land Down Under Is Leading the Way. Six excellent articles, representing early successes, remaining challenges, and ongoing efforts, provide a broad perspective of Australia’s power system transformation.
This issue of IEEE Power & Energy Magazine is set in Australia. Back then, the existential driver was the nuclear arms race and the possibility of planned or accidental annihilation. Although that threat remains, another is transforming the energy industry and electric power systems. The driver is climate change and the related efforts to reduce greenhouse gas emissions. Significant investments in alternative generation sources are dramatically changing the dynamics of operating the Australian grids. Higher penetrations of variable renewable resources and inverter-based resources (IBRs), such as batteries, are necessary to reach the regional emission goals. The changes that Australia is experiencing, and their plans to further reduce emissions, resonate with the transformations occurring in other parts of the world. What makes Australia unique is its large, electrically isolated area composed of two regionally controlled grids with local and overarching government policies. Although the issues are complex, Australia presents a microcosm for looking at a variety of dimensions where the energy transformation is occurring arguably more quickly. The diversity of issues covers the operation and planning of the power grids, their market coordination mechanisms, and the government policy and regulatory structures put in place to guide change and the interactions of the constituents.

Potential-Based Large-Signal Stability Analysis in DC Power Grids With Multiple Constant Power Loads

Publisher: name: IEEE
Year: 2021

We propose for the first time a comprehensive hyperlocal large-signal stability analysis that is adaptable to large-scale complex power grids.
The increasing adoption of power electronic devices may lead to large disturbance in DC power grids. Traditionally, the Brayton-Moser mixed potential theory is utilized to address large-signal stability (LSS) analysis. However, this theory proposes sufficient criteria only for large-signal global stability, which provides general but fuzzy information about the stability of DC microgrids. To solve this issue, we propose for the first time a comprehensive hyperlocal large-signal stability analysis (HL-LSS) that is adaptable to large-scale complex power grids. The novel proposed analysis studies the complex situation in nonlinear DC grids with multiple equilibrium points, including stability analysis of each equilibrium point and convergence analysis of state trajectories. The region of attraction (ROA) of microgrids is also estimated.

This paper presents a highly automated, novel method to enhance the accuracy of utility distribution feeder models to capture their performance by matching simulation results with corresponding field measurements.
Reliable and accurate distribution system modeling, including the secondary network, is essential in examining distribution system performance with high penetration of distributed energy resources (DERs). This paper presents a highly automated, novel method to enhance the accuracy of utility distribution feeder models to capture their performance by matching simulation results with corresponding field measurements. The method is demonstrated using an actual feeder from an electrical utility with high penetration of DERs. The method proposed uses advanced metering infrastructure (AMI) voltage and derived active power measurements at the customer level, and data acquisition systems (DAS) measurements at the feeder-head, in conjunction with an AC optimal power flow (ACOPF) to estimate customer active and reactive power consumption over a time horizon, while accounting for unmetered loads. The ACOPF uses the measured voltage magnitudes, derived active power measurements, and the feeder head measurements to obtain a complete active power and reactive power capture of the feeder loads. Additionally, the method proposed estimates both voltage magnitude and angle for each phase at the unbalanced distribution substation. The accuracy of the method developed is verified in two stages: by comparing the time-series power flow results obtained from the enhancement algorithm with OpenDSS results and with the field measurements available. The proposed approach seamlessly manages the data available from the optimization procedure through the final model verification automatically.
Foxtailing of Pinus caribaea var. hondurensis in peninsular Malaysia : frequency, growth rate and specific gravity
Creators: name: Ibrahim, Zakaria
Publisher: name: University of British Columbia
Year: 2010

description: Foxtailing is a common feature in the plantations of Pinus caribaea var. hondurensis Barrett and Golfari in Peninsular Malaysia. Frequency of foxtailing in Kemasul and Ulu Sedeli pine plantations, aged between 1 to 8 years, was found to vary between 4.3 to 36.0 percent. Ulu Sedeli plantation has 5.3 percent more foxtail than in Kemasul plantation. This study indicates that the occurrence of foxtailing varies with site and age. The most common form of foxtailing is the sub-terminal foxtail which constitutes about 60.0 percent of the foxtail population. The increasing proportion of sub-terminal to terminal foxtail with age of the trees suggests that foxtailing is a plastic trait. Average total height of foxtailed trees was greater than normal trees at all ages, however, larger diameters were evident only during the juvenile stage. The specific gravity of foxtailed trees was found to be slightly less dense than that of normal trees though the difference was not significant. Although breeding of true terminal foxtail trees may hold some promise of economic gains, the inherent limitations and foreseen problems render such proposition to be not feasible. Selection against foxtailing will continue to be a more practicable approach. Some future research studies on foxtailing are proposed: juvenile-mature correlation studies, long term growth and wood quality studies.
Possible economic consequences of air pollution on timber markets in certain European countries

Publisher: name: University of British Columbia

description: Traditional forest devastations in the Federal Republic of Germany (FRG) have in the past resulted in trade restrictions and price declines. The recent dieback problem in the FRG will result in a high quantity of salvage which will occur not only once but throughout several successive years. The situation in neighbouring countries is similar which will increase the problem for the FRG. Forest industries in dieback-affected countries will be able to increase roundwood consumption and exports. An aggravated dieback problem will result in price declines of forest products and/or trade restrictions. The planned implementation of trade restrictions by the European Economic Community (EEC) and/or the FRG due to dieback will be contrary to the General Agreement on Tariffs and Trade (GATT). Price declines and/or trade restrictions will affect Canadian exporters through reduction of exports to Europe. Canadian exports to other world markets may also be reduced due to increased competition by European exporters and former exporters to the European market.

This paper presents a comprehensive analysis of the converter-driven stability issues (fast- and slow- interactions) in power systems with root cause analysis.
New grid devices based on power electronics technologies are increasingly emerging and introduce two new types of stability issues into power systems, which are different from traditional power system stability phenomena and not well understood from a system perspective. This paper intends to provide the state of the art on this topic with a thorough and detailed review of the converter-driven stability issues in partial or all power electronics-based grids. The underlying and fundamental mechanisms of the converter-driven stability issues are uncovered through different types of root causes, including converter controls, grid strength, loads, and converter operating points. Furthermore, a six-inverter two-area meshed system is constructed as a representative test case to demonstrate these unstable phenomena. Finally, the challenges to cope with the converter-driven stability issues in future power electronics-based grids are identified to elucidate new research trends.

A white paper on Microgrids: Utility Challenges and Opportunities
The wide spread penetration of DERs across the transmission and distribution system along with recent developments in storage technologies, microgrids have emerged as one of the key domains in smart grid when we talk about system resiliency and reliability. With further participation of various market players MicroGrids concept has become an opportunity but also a challenge for some traditional and regulated utilities. It all depends upon the business strategy and future sustainability for any utility as to how they take it. The current whitepaper addresses many such aspects of MicroGrids,  components and characteristics, their operation, control and management with specific attention paid to microgrid opportunities for utilities through various business and operating models like DBOOM (Design, Build, Own, Operate, and Maintain) and public-private partnerships.

The complexion of power systems operations and planning is changing as solar and wind generation resources replace fossil fuels. Simultaneously, the electrification of fossil-based end uses is increasing the system load. Photovoltaic and wind resources are inverter-based, variable generation. Their voltage and frequency control mechanisms are fundamentally different than those of synchronous machines with a large spinning mass. A transition from fossil fuel dominated power systems requires rethinking operating principles and planning processes that have become engrained in grid management. New, unfamiliar operating paradigms can threaten power system reliability and stability. High-renewable system integration issues, exacerbated by increasing electricity demand, deserve careful study with early remedies to avoid dramatic socioeconomic impacts.

Decomposing Transmission Constraints for Decentralized Power System Optimization (Slides)
Creators: Feng Qiu
Publisher: name: IEEE
Year: 2022

One of the most complicating factors in decentralized optimization for power systems is the modeling of power flow equations. Existing formulations for direct current (or DC) power flows either have limited scalability or are very dense and unstructured, making them unsuitable for large-scale decentralized studies. In this work, we present a novel DC power flow formulation, based on sparsified injection shift factors, which has a decomposable block-diagonal structure, scales well for large systems, and can efficiently handle N-1 security requirements. Benchmarks on Multi-Zonal Security-Constrained Unit Commitment problems show that the proposed formulation can reliably and efficiently solve instances with up to 6,515 buses, with no convergence or numerical issues.

description: We analyze the relevance of finite-size effects to the electronic structure of long graphene nanoribbons using a divide and conquer density functional approach. We find that for hydrogen terminated graphene nanoribbons most of the physical features appearing in the density of states of an infinite graphene nanoribbon are recovered at a length of 40 nm. Nevertheless, even for the longest systems considered (72 nm long) pronounced edge effects appear in the vicinity of the Fermi energy. The weight of these edge states scales inversely with the length of the ribbon and they are expected to become negligible only at ribbons lengths of the order of micrometers. Our results indicate that careful consideration of finite-size and edge effects should be applied when designing new nanoelectronic devices based on graphene nanoribbons. These conclusions are expected to hold for other one-dimensional systems such as carbon nanotubes, conducting polymers, and DNA molecules.

This paper investigates the voltage stability of a power system where a load center is supplied by the grid through a transmission system along with an inverter-based generation located close to the load center.
Inverter-based power sources are increasingly being connected to the power system due to the global drive towards renewable generation. This paper investigates the voltage stability of a power system where a load center is supplied by the grid through a transmission system along with an inverter-based generation located close to the load center. It is also assumed that there is no additional reactive power compensation at the load center and voltage control at Point of Common Coupling (PCC) is done by the inverter. This is challenging as the inverter has an added duty. If the inverter controllers are not designed properly, the inverter could reach its current limit following to contingencies rendering it unable to support the voltage at the PCC. This is due to the fact that once the current limit is reached, the inverter ceases to function as a voltage source. When the voltage at the PCC is not supported, the active power transfer capability of both the inverter and the grid will be reduced. An effective control method is required under such circumstances to handle the active and reactive components of the inverter current. Various strategies exist for controlling the active and reactive components of the inverter current while preserving the current magnitude at the rated value. The necessity of an adequate control strategy to sustain long-term voltage stability following a system contingency is emphasized in this research. This paper further discusses three candidate control strategies and the effectiveness of the reactive current prioritizing approach as a solution for operation upon system contingencies.

description: Advancing maturity in mobile and legged robotics technologies is changing the landscapes where robots are being deployed and found. This innovation calls for a transformation in simultaneous localization and mapping (SLAM) systems to support this new generation of service and consumer robots. No longer can traditionally robust 2D lidar systems dominate while robots are being deployed in multi-story indoor, outdoor unstructured, and urban domains with increasingly inexpensive stereo and RGB-D cameras. Visual SLAM (VSLAM) systems have been a topic of study for decades and a small number of openly available implementations have stood out: ORB-SLAM3, OpenVSLAM and RTABMap. This paper presents a comparison of these 3 modern, feature rich, and uniquely robust VSLAM techniques that have yet to be benchmarked against each other, using several different datasets spanning multiple domains negotiated by service robots. ORB-SLAM3 and OpenVSLAM each were not compared against at least one of these datasets previously in literature and we provide insight through this lens. This analysis is motivated to find general purpose, feature complete, and multi-domain VSLAM options to support a broad class of robot applications for integration into the new and improved ROS 2 Nav2 System as suitable alternatives to traditional 2D lidar solutions.

The purpose of this paper is to review new or improved methods related to generator ground fault protection. Established stator ground fault protection schemes as referenced in IEEE Guides C37.101-2006 and C37.102-2006 are proven to be effective under the most common failure modes but may fall short in detecting faults that develop due to arcing faults or via uncommon mechanisms such as broken conductors. This paper discusses the limitations of existing protection schemes and presents several new approaches that could be considered to complement traditional ground fault protection schemes in high impedance grounded generators.

Itinerant ferromagnetism in the multiorbital Hubbard model: a dynamical mean-field study

description: In order to resolve the long-standing issue of how the itinerant ferromagnetism is affected by the lattice structure and Hund's coupling, we have compared various three-dimensional lattice structures in the single- and multiorbital Hubbard models with the dynamical mean-field theory with an improved quantum Monte Carlo algorithm that preserves the spin-SU(2) symmetry. The result indicates that {\it both} the lattice structure and the d-orbital degeneracy are essential for the ferromagnetism in the parameter region representing a transition metal. Specifically, (a) Hund's coupling, despite the common belief, is important, which is here identified to come from particle-hole scatterings, and (b) the ferromagnetism is a correlation effect (outside the Stoner picture) as indicated from the band-filling dependence.

description: FPGAs are quickly becoming available in the cloud as a one more heterogeneous processing element complementing CPUs and GPUs. There are many reports in the literature showing the potential for FPGAs to accelerate a wide variety of algorithms, which combined with their growing availability, would seem to also indicate a widespread use in many applications. Unfortunately, there is not much published research exploring what it takes to integrate an FPGA into an existing application in a cost-effective way and keeping the algorithmic performance advantages. Building on recent results exploring how to employ FPGAs to improve the search engines used in the travel industry, this paper analyses the end-to-end performance of the search engine when using FPGAs, as well as the necessary changes to the software and the cost of such deployments. The results provide important insights on current FPGA deployments and what needs to be done to make FPGAs more widely used. For instance, the large potential performance gains provided by an FPGA are greatly diminished in practice if the application cannot submit request in the most optimal way, something that is not always possible and might require significant changes to the application. Similarly, some existing cloud deployments turn out to use a very imbalanced architecture: a powerful FPGA connected to a not so powerful CPU. The result is that the CPU cannot generate enough load for the FPGA, which potentially eliminates all performance gains and might even result in a more expensive system. In this paper, we report on an extensive study and development effort to incorporate FPGAs into a search engine and analyse the issues encountered and their practical impact. We expect that these results will inform the development and deployment of FPGAs in the future by providing important insights on the end-to-end integration of FPGAs within existing systems.
Variation in resistance and virulence in the disease interaction between Melampsora rust (M. occidentalis) and black cottonwood (Populus trichocarpa)
Creators: name: Hsiang, Tom
Publisher: name: University of British Columbia
Year: 2010

description: Disease severity, as expressed by spore production rate was compared in a test of fourteen clones of black cottonwood (Populus trichocarpa) by ten isolates of Melampsora rust (M. occidentalis), all collected from their natural pathosystem. Spore production rate was measured by average daily production on leaf disks during twice the latent period in days. The overall average uredospore production during the time from inoculation to twice the latent period was 650 spores/disk/day. Latent period ranged from 6 to 12 days with a median at 8 days. Clones as well as isolates differed significantly in their contributions to spore production rates, while there was no indication of specific differential interaction. The lack of qualitative resistance and virulence indicates that qualitative interactions do not play a major role in disease in this natural pathosystem. This finding holds the promise that black cottonwood resistance will not be devastatingly overcome when used in plantations.
