description: Just-in-time supply chains have become increasingly popular in past decades. However, these are particularly vulnerable when logistic routes are blocked, manufacturing capacities are limited or customs are under strain, as has been seen in the last few years. The principle of just-in-time delivery requires a coordinated production and material flow along the entire supply chain. Challenges in the supply chain can lead to various disruptions, so that certain manufacturing jobs must be changed, postponed or cancelled, which will then impact supply down the line up to the consumer. Nowadays, many planning and control processes in the event of a disturbance are based on the procedural knowledge of employees and undertaken manually by those. The procedures to mitigate the negative effects of disturbances are often quite complex and time-critical, making disturbance management highly challenging. In this paper, we introduce a real-world use case where we automate the currently manual reschedule of a production plan containing unavailable jobs. First, we analyse existing literature regarding the classification of disturbances encountered in similar use cases. We show how we automate existing manual disturbance management and argue that employing stochastic optimization allows us to not only promote future jobs but to on-the-fly create entirely new plans that are optimized regarding throughput, energy consumption, material waste and operator productivity. Building on this routine, we propose to create a Bayesian estimator to determine the probabilities of delivery times whose predictions we can then reintegrate into our optimizer to create less fragile schedules. Overall, the goals of this approach are to increase robustness in production planning and control.

Banks and banking

description: The consequences of bank distress for the economy during the Depression remain an area of unresolved controversy. Since John M. Keynes (1931) and Irving Fisher (1933), macroeconomists have argued that bank distress magnified the extent of the economic decline during the Depression. As the intermediaries controlling money and credit, banks were in a special position to transmit their distress to other sectors. But the mechanism through which banking distress mattered for the economy has been hotly contested.

description: We investigate the effects induced by spin polarization in the contacts attached to a serial double quantum dot. The polarization generates effective magnetic fields and suppresses the Kondo effect in each dot. The super-exchange interaction ($J_{\mathrm{AFM}}$), tuned by the inter-dot tunnelling rate $t$, can be used to compensate the effective fields and restore the Kondo resonance when the contact polarizations are aligned. As a consequence, the direction of the spin conductance can be controlled and even reversed using electrostatic gates alone. Furthermore, we study the associated two-impurity Kondo model and show that a ferromagnetic exchange coupling ($J_{\mathrm{FM}}$) leads to an effective spin-1 exchange-anisotropic Kondo model which exhibits a quantum phase transition in the presence of partially polarized contacts.

description: These guidelines on co-design toold are a deliverable within LOOPER (Learning Loops in the Public Realm), a JPI Europe funded research project with Living Labs in Brussels, Manchester and Verona. The aim of this project is to build a participatory co-creation methodology and platform to demonstrate ‘learning loops’, bringing together citizens, stakeholders and policy-makers to iteratively learn how to address urban challenges such as road safety, traffic calming, air and noise pollution. This deliverable provides an analysis and evaluation of online, digital and face-to-face tools that can enhance a co-creation process in Living Labs, and in particular the co-design stage. These guidelines provide both an overview on the breadth of tools available and 21 in-depth factsheets on tools that are promising for LOOPER. As the Living Labs become more concrete, resources can be chosen according to the evolving needs. Methodologically, this review is based on an online scoping of potential tools using a broad set of keywords. Selection of tools may therefore be impacted by the subjective bias of the authors and dependent of a given tool’s publicity online. A table with all reviewed tools can be found in the appendix. For face-to-face interaction, a wealth of handbooks has been found. A good start are the introductory chapters of the Participatory Methods Toolkit by the King Bauduin Foundation, followed by a look-over of the 23 methods in the Collective Action Toolkit by Frog Design or the bootcamp bootleg of Stanford’s d-school. The urb@exp LAB kit can be employed at the inception of the Living Lab or if direction and structure is lacking during its implementation. When reaching the creative stage, Stanford’s virtual crash course can be a great engaging 90-minute activity for participants to provide them with creative energy and methods to tackle their problems. Online co-creation tools have a great variety of functionalities that can be incorporated into online co-creation platforms. As communication is of vital importance in the co-creation process, a co-creation platform should always include a messaging and spatial commenting functionality. Which other tools are most useful depends on the needs of a platform, the technical knowledge of participants and practitioners, and available financial resources. For ready-to-use co-creation solutions, take a look at TransformCity and Citizenlab.

description: We explain the origins of the Panic of 1857, examine its spread, and compare state banking systems's responses. We describe the decline in western land and railroad investments and the consequent stress on securities brokers and banks in eastern cities, and trace the transmission of the shock to other regions. Bank performance depended not only on regional conditions and links to eastern banks, but on the ability to coordinate behavior. Southern branch banks and coinsuring banks in Ohio and Indiana were particularly successful.

description: Particles that are heavy compared to the electroweak scale ($M \gg m_W$), and that are charged under electroweak SU(2) gauge interactions display universal properties such as a characteristic fine structure in the mass spectrum induced by electroweak symmetry breaking, and an approximately universal cross section for scattering on nuclear targets. The heavy particle effective theory framework is developed to compute these properties. As illustration, the spin independent cross section for low-velocity scattering on a nucleon is evaluated in the limit $M \gg m_W$, including complete leading-order matching onto quark and gluon operators, renormalization analysis, and systematic treatment of perturbative and hadronic-input uncertainties.

description: Industrial energy systems are being transformed to decrease energy costs, reduce emissions, and ensure security of supply. The increasing integration of renewable energies and industrial waste heat leads to complex and interconnected industrial energy systems. At the same time, the decarbonization of the heating sector is still in its infancy and possibilities are discussed to make excess heat from industrial companies available for building supply via district heating networks or to use district heating for thermal energy supply in the industrial sector. In this paper, we present an optimization-based investment planning approach to calculate the optimal dimensioning of a potential heat transfer station connecting industrial sites to district heating systems. The approach is based on a model library that includes typical components of industrial energy systems. Moreover, it integrates different energy demands such as heating, cooling, or electricity of production systems and sites as well as waste heat of production processes depending on predominant temperature levels. The approach manages to include transformation strategies of the industrial energy system by integrating different scenarios using regret optimization, giving decision makers a better overview of the impact of the investment in a heat transfer station on the overall factory planning. The approach is applied to the planning process of an industrial company. In the use case, a positive net present value shows the benefits of an investment in a heat transfer station. Moreover, energy costs and carbon dioxide emissions can be reduced over the planning horizon and through the higher utilization of waste heat as well as the more efficient use of energy systems.

description: Industrial direct current (DC) microgrids offer multiple advantages for production factories. They enable higher energy and resource efficiency not only for the production energy supply but also for integrating renewable energy resources. The basic control method of DC microgrids, namely droop control, fits the industrial application due to its decentralized and robust nature. However, in the case of droop control, the DC bus voltage deviates from the nominal value for slowly fluctuating load situations. For this reason, an additional control level for voltage restoration, called secondary control or source management, is necessary. This paper presents hierarchical control for voltage restoration in industrial DC microgrids. The control shifts the current supplied to the DC bus in case the load increases over or decreases below a defined voltage band for a certain period. In addition, the designed control is tested on a real industrial DC microgrid which includes typical industrial loads of up to 50 kW, such as robots of different sizes and CNC machine tools. The control performance with different parameters of the source management is assessed. The results show that the designed control restores the voltage level without creating instabilities in the microgrid for all tested scenarios.

description: While the shooting [in Tucson, Arizona] was in some respects one very unstable man acting alone, it is also intellectually and politically dishonest to ignore the political context in which this happens. As our politics became increasingly saturated with violent images, use of the term revolution, replacing the word stop or block with kill, threats by candidates that if elections did not turn out their way it might be necessary to resort to violence, the chances of something like this happening grew. Military analogies have long been part of the language of political campaigns in the US, but in the last few years this rhetoric has moved to a different level. While the right wing should not be blamed for this incident, they probably should take this opportunity to take a closer look at the potential consequences of what they have been saying and doing these last two years, but so far they have not.

description: External factors such as climate change and the current energy crisis due to global conflicts are leading to the increasing relevance of energy consumption and energy procurement in the manufacturing industry. In addition to the growing call for sustainability, companies are increasingly struggling with rising energy costs and the reliability of the power grid, which endangers the competitiveness of companies and regions affected by high energy prices. Appropriate measures for energy-efficient and, not least, energy-flexible production are necessary. In addition to innovations and optimizations of plants and processes, digital energy platforms for the visualization, analysis, optimization, and control of energy flows are becoming essential. Over time, several digital energy platforms emerged on the market. The number and the different functionalities of the platforms make it challenging for classic manufacturing companies to keep track and select the right digital energy platform. In literature, the characteristics and functionalities of digital energy platforms have already been identified and structured. However, a classification of existing platforms into archetypes makes it easier for companies to select the platforms providing the missing functionality. To tackle this issue, we conducted an explorative and data-driven cluster analysis based on 49 existing digital energy platforms to identify digital energy platform archetypes and derive implications for research and practice. The results show five different archetypes that differ primarily in terms of functionalities on energy market integration. The identified archetypes provide a well-founded overview of the similarities and differences of digital energy platforms. Decision makers in manufacturing companies will benefit from the archetypes in future analyses as decision support in procurement processes and modifications of digital energy platforms.

description: The failure of the super committee to agree to a compromise that would lead to reigning in the national debt and spearhead a more balanced budget could only have come as a surprise to somebody who has spent the last decade or so living under a rock. The notion that a smaller bipartisan microcosm of congress could resolve these problems and reach an effective compromise was always something of a fantasy. The super committee quickly devolved into a mixture of partisan grandstanding and posturing, predictable and tiresome ultimatums about taxes, muscle flexing by powerful lobbies and a complete absence of political courage. In short, it looked quite a bit like congress has over the past few years.

description: Industrial manufacturing plants, including machine tools, robots, and elevators, perform dynamic acceleration and braking processes. Recuperative braking results in an increased voltage in the machines' direct current (DC) links. In the case of a diode rectifier, a braking resistor turns the surplus of energy into lost heat. In contrast, active rectifiers can feed the braking energy back to the AC grid, though they are more expensive than diode rectifiers. DC link-coupled energy storage systems are one possible solution to downsize the supply infrastructure by peak shaving and to harvest braking energy. However, their control heavily depends on the applied load profiles that are not known in advance. Especially for retrofitted energy storage systems without connection to the machine control unit, load profile recognition imposes a major challenge. A self-tuning framework represents a suitable solution by covering system identification, proof of stability, control design, load profile recognition, and forecasting at the same time. This paper introduces autonomous load profile recognition in industrial DC links using an audio search algorithm. The method generates fingerprints for each measured load profile and saves them in a database. The control of the energy storage system then has to be adapted within a critical time range according to the identified load profile and constraints given by the energy storage system. Three different load profiles in four case studies validate the methodology.

description: We study the spatio-temporal evolution of wave packets in one-dimensional quasiperiodic lattices which localize linear waves. Nonlinearity (related to two-body interactions) has destructive effect on localization, as recently observed for interacting atomic condensates [Phys. Rev. Lett. 106, 230403 (2011)]. We extend the analysis of the characteristics of the subdiffusive dynamics to large temporal and spatial scales. Our results for the second moment $m_2$ consistently reveal an asymptotic $m_2 \sim t^{1/3}$ and intermediate $m_2 \sim t^{1/2}$ laws. At variance to purely random systems [Europhys. Lett. 91, 30001 (2010)] the fractal gap structure of the linear wave spectrum strongly favors intermediate self-trapping events. Our findings give a new dimension to the theory of wave packet spreading in localizing environments.

description: The best thing Obama can do in this speech is to reassert his relevance by speaking frankly about the economy, stressing his awareness of the problems more than the bills he has passed since becoming president. He also can use this speech not as an opportunity to, yet again, recommit himself to reaching across the aisle and working with the Republicans, but to remind the Congress and the country that Obama is the one nationally-elected official and that he remains more popular than either party in congress. He can do this by challenging the Republican Party, not to support Obama's agenda, but to work with him in putting partisan interests aside in favor of doing what is good for the country. The president needs to demonstrate to the American people and to Congress that he is a leader and is going to act like one. President Obama can do this best not through listing accomplishments or proposals, but by striking a tone that indicates both an understanding of the problems and fierce urgency of addressing them rather than backing down after the shellacking. This approach will require some political courage and will come with some short-term consequences, but the easy option is to play nice and sink into political irrelevance.
High-performance real-time motion control for precision systems
Creators: name: Smeds, Kristofer S.
Publisher: name: University of British Columbia
Year: 2011

description: Digital motion controllers are used almost exclusively in automated motion control systems today. Their key performance parameters are controller execution speed, timing consistency, and data accuracy. Most commercially available controllers can achieve sampling rates up to 20kHz with several microseconds of timing variation between control cycles. A few state-of-the art control platforms can reach sampling rates of around 100kHz with several hundred nanoseconds of timing variation. There exist a growing number of emerging high-speed high-precision applications, such as diamond turning and scanning probe microscopy, that can benefit from digital controllers capable of faster sampling rates, more consistent timing, and higher data accuracy. This thesis presents two areas of research intended to increase the capabilities of digital motion controllers to meet the needs of these high-speed high-precision applications. First, it presents a new high-performance real-time multiprocessor control platform capable of 1MHz control sampling rates with less than 6ns RMS control cycle timing variation and 16-bit data acquisition accuracy. This platform also includes software libraries to integrate it with Simulink for rapid controller development and LabVIEW for easy graphical user interface development. This thesis covers the design of the control platform and experimentally demonstrates it as a motion controller for a fast-tool servo machine tool. Second, this thesis investigates the effect of control cycle timing variations (sampling jitter and control jitter) on control performance, with an emphasis on precision positioning degradation. A new approximate discrete model is developed to capture the effects of jitter, enabling an intuitive understanding of it's effects on the control system. Based on this model, analyses are carried out to determine the relationship between jitter and positioning error for two scenarios: regulation error from jitter's interaction with measurement noise; and tracking error from jitter's interaction with a deterministic reference command. Further, several practical methods to mitigate the positioning degradation due to jitter are discussed, including a new jitter compensator that can be easily added to an existing controller. Through simulations and experiments performed on a fast-tool servo machine tool, the model and analyses are validated and the positioning degradation arising from jitter is clearly demonstrated.

description: Hidden Markov models (HMMs) permit a natural and flexible way to model time-sequential data. The ease of concatenation and time-warping algorithms implementation on HMMs suit them very well for segmentation and content based audio classification applications, as is clear from their extended and successful use on speech recognition applications. Speech has a natural basic unit, the phone, which normally delimits the number of models to one per phone. Moreover, knowledge of the speech structure facilitates the choice of the model parameters. When modeling generic audio, on other hand, the lack of a natural basic unit, and the absence of a clear structure, make the selection and the parameter estimation of an optimal set of HMMs difficult. In this paper we present different approaches to select and estimate the HMM parameters of a set of representative generic audio classes. We compare these approaches in the context of a content- based classification application using the MuscleFish database. The models are first found through frame clustering or by traditional EM techniques under some specific selection criteria, such as the Bayesian information criterion. Further discriminative training of the initial models considerably improve their performance in the content-based classification task, obtaining results comparable with the ones obtained, for the same task, by inherently discriminative classification methods, such as support vector machines, while preserving the intrinsic flexibility of HMMs.

description: We propose an algebraic lattice supersymmetry formulation which has an exact supersymmetry on the lattice. We show how lattice version of chiral conditions can be imposed to satisfy an exact lattice supersymmetry algebra. The species doublers of chiral fermions and the corresponding bosonic counterparts can be accommodated to fit into chiral supermultiplets of lattice supersymmetry and thus lattice chiral fermion problem does not appear. We explicitly show how N=2 Wess-Zumino model in one and two dimensions can be formulated to keep exact supersymmetry for all super charges on the lattice. The momentum representation of N=2 lattice chiral sypersymmetry algebra has lattice periodicity and thus momentum conservation should be modified to a lattice version of sine momentum conservation, which generates nonlocal interactions and leads to a loss of lattice translational invariance. It is shown that the nonlocality is mild and the translational invariance is recovered in the continuum limit. In the coordinate representation a new type of product is defined and the difference operator satisfies Leibnitz rule and an exact lattice supersymmetry is realized on this product.

description: Tandem acoustic modeling consists of taking the outputs of a neural network discriminantly trained to estimate the phone-class posterior probabilities of speech, and using them as the input features of a conventional distribution-modeling Gaussian mixture model (GMM) speech recognizer, thereby employing two acoustic models in tandem. This structure reduces the error rate on the Aurora 2 noisy English digits task in more than 50% compared to the HTK baseline. Even though there are some reasonable hypothesis to explain this improvement, the origins are still unclear. This paper introduces the use of visualization tools for error analysis of some variations of the tandem system. The error behavior is first analyzed using word-level confusion matrices. Posteriorgrams (displays of the variation in time of per-phone posterior probabilities) provide for further analysis. The results of corroborate our previous hypothesis that the gains from tandem modeling arise from the very different training and modeling schemes of the two acoustic models.

description: The interaction between a high-frequency dilational mode of a thin dielectric film and an optical cavity field is studied theoretically in the membrane-in-the-middle setup. A derivation from first principles leads to a multi-mode optomechanical Hamiltonian where multiple cavity modes are coupled by the thickness variation of the membrane. For membrane thicknesses on the order of one micron, the frequency of this dilational mode is in the GHz range. This can be matched to the free spectral range of the optical cavity, such that the mechanical oscillator will resonantly couple cavity modes at different frequencies. Furthermore, such a large mechanical frequency also means that the quantum ground state of motion can be reached with conventional refrigeration techniques. Estimation of the coupling strength with realistic parameters suggests that optomechanical effects can be observable with this dilational mode. It is shown how this system can be used as a quantum limited optical amplifier. The dilational motion can also lead to quantum correlations between cavity modes at different frequencies, which is quantified with an experimentally accessible two-mode squeezing spectrum. Finally, an explicit signature of radiation pressure shot noise in this system is identified.

Spin-orbit coupled Fermi liquid theory of ultra-cold magnetic dipolar fermions

description: We investigate Fermi liquid states of the ultra-cold magnetic dipolar Fermi gases in the simplest two-component case including both thermodynamic instabilities and collective excitations. The magnetic dipolar interaction is invariant under the simultaneous spin-orbit rotation, but not under either the spin or the orbit one. Therefore, the corresponding Fermi liquid theory is intrinsically spin-orbit coupled. This is a fundamental feature of magnetic dipolar Fermi gases different from electric dipolar ones. The Landau interaction matrix is calculated and is diagonalized in terms of the spin-orbit coupled partial-wave channels of the total angular momentum J. The leading thermodynamic instabilities lie in the channels of ferromagnetism hybridized with the ferronematic order with J = 1+ and the spin-current mode with J = 1-, where + and - represent even and odd parities, respectively. An exotic propagating collective mode is identified as spin-orbit coupled Fermi surface oscillations in which spin distribution on the Fermi surface exhibits a topologically nontrivial hedgehog configuration.

description: Sustainability is getting more and more attention in society, industry, and research. Companies are increasingly focusing on sustainable practices to meet different requirements. Industrial maintenance, which tends to be considered sustainable, is now more frequently examined in research for its actual sustainability, and various approaches to the design of maintenance are being presented. In this context, the term sustainable maintenance is not uniformly defined. There are different underlying assumptions about the term sustainability within the maintenance function itself, whether it is a support-function to enable sustainable manufacturing or a standalone function to improve sustainability in manufacturing companies by itself. For this reason, this study defines the term Sustainable Maintenance based on previous publications. For this purpose, a systematic literature review of 46 publications identified as relevant to the topic is conducted, and then a definition is derived via the Genus Proximum et Differentia Specifica by Aristotle through the distinction of sustainable maintenance from traditional maintenance.
