description: We consider the ramp metering problem for a freeway stretch modeled by the Cell Transmission Model. Assuming perfect model knowledge and perfect traffic demand prediction, the ramp metering problem can be cast as a finite horizon optimal control problem with the objective of minimizing the Total Time Spent, i.e., the sum of the travel times of all drivers. For this reason, the application of Model Predictive Control (MPC) to the ramp metering problem has been proposed. However, practical tests on freeways show that MPC may not outperform simple, distributed feedback policies. Until now, a theoretical justification for this empirical observation was lacking. This work compares the performance of distributed, non-predictive policies to the optimal solution in an idealised setting, specifically, for monotonic traffic dynamics and assuming perfect model knowledge. To do so, we suggest a distributed, non-predictive policy and derive sufficient optimality conditions for the minimization of the Total Time Spent via monotonicity arguments. In a case study based on real-world traffic data, we demonstrate that these optimality conditions are only rarely violated. Moreover, we observe that the suboptimality resulting from such infrequent violations appears to be negligible. We complement this analysis with simulations in non-ideal settings, in particular allowing for model mismatch, and argue that Alinea, a successful, distributed ramp metering policy, comes close to the ideal controller both in terms of control behavior and in performance.

description: We propose the existence of a lower bound on the energy of pure neutron matter (PNM) on the basis of unitary-gas considerations. We discuss its justification from experimental studies of cold atoms as well as from theoretical studies of neutron matter. We demonstrate that this bound results in limits to the density-dependent symmetry energy, which is the difference between the energies of symmetric nuclear matter and PNM. In particular, this bound leads to a lower limit to the volume symmetry energy parameter $S_0$. In addition, for assumed values of $S_0$ above this minimum, this bound implies both upper and lower limits to the symmetry energy slope parameter $L$, which describes the lowest-order density dependence of the symmetry energy. A lower bound on the neutron-matter incompressibility is also obtained. These bounds are found to be consistent with both recent calculations of the energies of PNM and constraints from nuclear experiments. Our results are significant because several equations of state that are currently used in astrophysical simulations of supernovae and neutron star mergers, as well as in nuclear physics simulations of heavy-ion collisions, have symmetry energy parameters that violate these bounds. Furthermore, below the nuclear saturation density, the bound on neutron-matter energies leads to a lower limit to the density-dependent symmetry energy, which leads to upper limits to the nuclear surface symmetry parameter and the neutron-star crust-core boundary. We also obtain a lower limit to the neutron-skin thicknesses of neutron-rich nuclei. Above the nuclear saturation density, the bound on neutron-matter energies also leads to an upper limit to the symmetry energy, with implications for neutron-star cooling via the direct Urca process.

Energy harvesting for heavy haul rail application

Year: 2017

description: Heavy haul vehicles operating in remote regions are particularly vulnerable to compounding deterioration due to the high levels of mechanical stress during operation coupled with low levels of maintenance inspection. The application of structural health monitoring is appealing in this operating environment due to its autonomous nature, and the potential cost savings due to early detection of mechanical damage. Without any monitoring system in place, predicting the reliability and mechanical failure modes of heavy haul rail vehicles is difficult. However autonomous structural health monitoring systems such as the Instrumented Ore Car (IOC) allow early detection of rail and vehicle anomalies to minimise damage and reduce the risk of derailment leading to significant down time and cost. A particular issue experienced by wireless systems is the lack of electrification. Primary batteries are often the easiest solution however they are typically not suitable due to their limited energy capacity and high maintenance cost. A more appealing solution is energy harvesting from local sources of waste energy. The ambient operating environment of heavy haul rail vehicles were examined with the aim of finding a suitable source of waste energy, and potential transduction approaches were considered. It was decided that vibration energy harvesting using electromagnetic transduction was the most suitable energy harvesting method. An inertial based 1-DoF electromagnetic energy harvester was designed and manufactured to generate practical levels of power (typically in the range of 10 - 100 mW for structural health monitoring sensor systems). The device was designed using finite element analysis and tested in the laboratory using sinusoidal and PSD input based on measured railcar vibration. A substantial amount of power was generated using the 1-DoF device with experimental results agreeing well with model predictions. Furthermore to improve power generation for heavy haul rail application, a second design was introduce utilising a 2-DoF coupled oscillating system. The 2-DoF design demonstrated significant improvements to the power generation and was installed on the railcar to provide an in-service demonstration and to validate the experimental and model predictions.

description: The static region outside the event horizon of an asymptotically anti de Sitter black hole has a conformal timelike boundary $\mathscr{I}$ on which boundary conditions have to be imposed for the evolution of linear fields from initial data to be a well posed problem. Only homogeneous Dirichlet, Neumann or Robin conditions preserve the action of the background isometry group on the solution space. We study the case in which the modal decomposition of the linear field leads to potentials not diverging at the conformal timelike boundary. We prove that there is always an instability if Robin boundary conditions with large enough $γ$ (the quotient between the values of the derivative of the field and the field at the boundary) are allowed. We explain the origin of this instability, show that for modes with nonnegative potentials there is a single unstable state and prove a number of properties of this state. Although our results apply in general to 1+1 wave equations on a half infinite domain with a potential that is not singular at the boundary, our motivation is to analyze the gravitational stability of the four dimensional Schwarzschild anti de Sitter black holes (SAdS${}_4$) in the context of the black hole non modal linear stability program initiated in Phys.\ Rev.\ Lett.\ {\bf 112}, 191101 (2014), and the related supersymmetric type of duality exchanging odd and even modes. We prove that this symmetry is broken except when a combination of Dirichlet conditions in the even sector and a particular Robin condition in the odd sector is enforced, or viceversa, and that only the first of these two choices leads to a stable dynamics.

description: III-Nitride based materials have gained prominence for various applications, especially in the field of optoelectronics research for their many attractive properties like a direct and wide band-gap. Further spintronics has been a key component of the research roadmap in recent times along with nanostructured semiconductors for possible performance enhancements. Therefore, we have used the III-Nitride based semiconductor for preparing the Cr-doped dilute magnetic semiconductor (DMS) and subsequently the spin-LED to verify spin injection till 200 K with the DMS. We could make a superluminescent LED with a InGaN-based nanowire device as well as a room temperature nano-laser by incorporating external reflecting elements, wherein the nanowires were prepared by a novel method. In future, work in the direction of studying the transient electron and spin dynamics in the 1-D nanostructures and integrating the DMS to inject spin polarized carriers into the nanowire laser would be interesting and fruitful with many practical applications.

Formation of inner planets in the presence of a Cold Jupiter: orbital evolution and relative velocities of planetesimals

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: We investigate the orbital evolution of planetesimals in the inner disk in the presence of nebula gas and a (proto-) cold Jupiter. By varying the mass, eccentricity, and semi-major axis of the planet, we study the dependence of the relative velocities of the planetesimals on these parameters. For classic small planetesimals ($10^{16}-10^{20} $g) whose mutual gravitational interaction is negligible, gas drag introduces a size-dependent alignment of orbits and keeps the relative velocity low for similar-size bodies, while preventing orbital alignment for different-size planetesimals. Regardless of the location and the mass ratio of the planetesimals, increasing the mass and eccentricity or decreasing the orbital distance of the planet always leads to higher relative velocities of planetesimals. However, for massive planetesimals, the interplay of viscous stirring, gas damping, and secular perturbation results in lower velocity dispersion of equal-size planetesimals when the planet is more massive or when it is located on a closer or more eccentric orbit. The random velocities of such planetesimals remain almost unperturbed when the planet is located beyond Jupiter's current orbit, or when it is less massive or less eccentric than Jupiter. Unlike small planetesimals, such large planetesimals can grow in a runaway fashion as in the unperturbed case. Our results imply that the presence of a cold Jupiter does not impede the formation of inner rocky planets through planetesimal accretion, provided that the planetesimals are initially large.

description: Functional spintronic devices rely on spin-charge interconversion effects, such as the reciprocal processes of electric field-driven spin torque and magnetization dynamics-driven spin and charge flow. Both damping-like and field-like spin-orbit torques have been observed in the forward process of current-driven spin torque and damping-like inverse spin-orbit torque has been well-studied via spin pumping into heavy metal layers. Here we demonstrate that established microwave transmission spectroscopy of ferromagnet/normal metal bilayers under ferromagnetic resonance can be used to inductively detect the AC charge currents driven by the inverse spin-charge conversion processes. This technique relies on vector network analyzer ferromagnetic resonance (VNA-FMR) measurements. We show that in addition to the commonly-extracted spectroscopic information, VNA-FMR measurements can be used to quantify the magnitude and phase of all AC charge currents in the sample, including those due to spin pumping and spin-charge conversion. Our findings reveal that Ni$_{80}$Fe$_{20}$/Pt bilayers exhibit both damping-like and field-like inverse spin-orbit torques. While the magnitudes of both the damping-like and field-like inverse spin-orbit torque are of comparable scale to prior reported values for similar material systems, we observed a significant dependence of the damping-like magnitude on the order of deposition. This suggests interface quality plays an important role in the overall strength of the damping-like spin-to-charge conversion.

description: Illusie has suggested that one should think of the classifying group of $M_X^{gp}$-torsors on a logarithmically smooth curve $X$ over a standard logarithmic point as a logarithmic analogue of the Picard group of $X$. This logarithmic Picard group arises naturally as a quotient of the algebraic Picard group by lifts of the chip firing relations of the associated dual graph. We connect this perspective to Baker and Norine's theory of ranks of divisors on a finite graph, and to Amini and Baker's metrized complexes of curves. Moreover, we propose a definition of a combinatorial rank for line bundles on $X$ and prove that an analogue of the Riemann-Roch formula holds for our combinatorial rank. Our proof proceeds by carefully describing the relationship between the logarithmic Picard group on a logarithmic curve and the Picard group of the associated metrized complex. This approach suggests a natural categorical framework for metrized complexes, namely the category of logarithmic curves.

description: Villages are the backbone of the nation and a smart village means such a village that can provide various services needed in day-to-day life to the villagers effectively and efficiently. The overall objective of this research is to assess the practicability of the smart village in the hilly region of Nepal with a special reference to Sandakpur Rural Municipality. The study covered the locality within Maipokhari and Sulubung village of Sandakpur Rural Municipality. A scheduled questionnaire survey was done with 45 respondents under the pandemic of COVID-19 to find the present status of the health, education, governance, services, water supply, irrigation in the area along with their perception of smart village practicability. From the literature review of the various paper about smart villages throughout the world, some of the characteristics were adopted and these were assessed in the study area. Five points Likert scale was used on ranking smart village feature and Chi-Square test is done to determine the significance of respondent’s opinions for the variables from the collected data followed by benefit-cost ratio, NPV and IRR for economic feasibility. After the analysis of data with the Five-Point Likert Scale, ratings on smart features like Smart Utilization of Resources, Smart Living, Smart Governance, Smart Village Services, Smart Technology, Smart Tourism, and Gender Equity and Women Equity were given as Fair (2.82), Fair (3.02), Fair (2.93), Fair (3.17), Fair (3.2), Good (2.42) and Poor (3.46) respectively. The chisquare test showed that the majority of respondents supported the perspective toward Smart Village features as fair. B/C ratio was found as 4.98 and 2.85 at 6.5% and 10% discount rate, NPV was found as Rs 1,550,474,977 and Rs 715,758,502.7 at 6.5% and 10% discount rate and IRR was found as 18.32 % for 30 year analysis period which assures smart village can be a better option for the sustainable village. Smart villages can only be possible with long-term planning, strategy and investment. With the adoption of features of the smart village, the study area can be converted into a smart village but it may take time to incorporate these features completely. Only with a gradual development of infrastructures and facilities, Maipokhari and Sulubung villages of Sandakpur Rural Municipality and even other villages can be developed as smart village. But the different village has a different characteristic, so the development model of one village could be only a reference for the further analysis of a particular village.

Development of space frame structures using pultruded GFRP components
Creators: name: Yang, Xiao
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Fiber reinforced polymer (FRP) materials are well known for their excellent properties such as high strength, light weight and corrosion resistance. Compared with other reinforcements, the use of glass fibers further reduces raw material costs and introduces environmentally friendly characteristics such as low energy consumption and low carbon dioxide emissions. Pultrusion is a continuous and highly economical manufacturing method for producing constant cross-section FRP structural profiles. All the above advantages encourage the use of pultruded glass fiber reinforced polymer (GFRP) materials for civil engineering applications. However, compared with steel, GFRP materials have lower elastic modulus, lower shear strength, and poor ductility. The low elastic modulus poses a concern for design serviceability considering the low material stiffness. The low shear strength implies that premature shear failure may prohibit full utilization of the material’s potential. The lack of material ductility may prevent the incorporation of pre-failure warnings. It seems, however, that these disadvantages can be overcome at the structural level by incorporating pultruded GFRP profiles into a space frame configuration, as a structural form with high inherent structural stiffness because of the load distribution in a three-dimensional configuration. The structural members in a space frame are subjected mainly to axial rather than shear loading. Besides, space frame structures assembled by linear elastic FRP materials can achieve large nonlinear deformation behavior at structural level through progressive buckling of the members in compression. In this PhD study, a connection system is developed to integrate the pultruded GFRP profiles into a space frame structure and the mechanical performance of the resulting space frame is explored.

description: Using a braid group representation based on the Temperley-Lieb algebra, we construct braid quantum gates that could generate entangled $n$-partite $D$-level qudit states. $D$ different sets of $D^n\times D^n$ unitary representation of the braid group generators are presented. With these generators the desired braid quantum gates are obtained. We show that the generalized GHZ states, which are maximally entangled states, can be obtained directly from these braid quantum gates without resorting to further local unitary transformations. We also point out an interesting observation, namely for a general multi-qudit state there exists a unitary braid quantum gate based on the Temperley-Lieb algebra that connects it from one of its component basis states, if the coefficient of the component state is such that the square of its norm is no less than $1/4$.

description: Historical photos are valuable for their cultural and economic significance, but can be difficult to identify accurately due to various challenges such as low-quality images, lack of corroborating evidence, and limited research resources. Misidentified photos can have significant negative consequences, including lost economic value, incorrect historical records, and the spread of misinformation that can lead to perpetuating conspiracy theories. To accurately assess the credibility of a photo identification (ID), it may be necessary to conduct investigative research, use domain knowledge, and consult experts. In this paper, we introduce DoubleCheck, a quality assessment framework for verifying historical photo IDs on Civil War Photo Sleuth (CWPS), a popular online platform for identifying American Civil War-era photos using facial recognition and crowdsourcing. DoubleCheck focuses on improving CWPS's user experience and system architecture to display information useful for assessing the quality of historical photo IDs on CWPS. In a mixed-methods evaluation of DoubleCheck, we found that users contributed a wide diversity of sources for photo IDs, which helped facilitate the community's assessment of these IDs through DoubleCheck's provenance visualizations. Further, DoubleCheck's quality assessment badges and visualizations supported users in making accurate assessments of photo IDs, even in cases involving ID conflicts.

description: We investigate the stability and critical velocity of a weakly interacting Bose gas flowing in a random potential. By applying the Bogoliubov theory to a disordered Bose system with a steady flow, the condensate density and the superfluid density are determined as functions of the disorder strength, flow velocity, and temperature. The critical velocity, at which the steady flow becomes unstable, is calculated from the spectrum of hydrodynamic excitation. We also show that in two dimensions the critical velocity strongly depends on the system size.

description: This research considers the effect of reward system on organizational performance. Reward programs helps organizations to motivate its employees in order to attain the organization identified goals and objectives. Many organizations face the dilemma around what the ideal reward strategy should be in place in order to increase the motivation of employees and as well as the organizational performance. The purpose of this research was to investigate the effect of reward system on organizational performance. A questionnaire was developed us ing reward categories from the Worldat Work Total Reward Model. This was distributed to recruit professional to accountant level of employees found at Addis Ababa branch using simple random sampling of Carlvalho's sample determination method. Data was gathered to comprehend the satisfaction level of employees on financial and non-financial reward provided by the bank and effect of reward system on organizational performance. A sample of 67 respondents participated in the survey and their opinion was analyzed using SPSS version23. The result of the survey indicated that the Majority of respondents were not satisfied with both the financial and non financial reward proved by the bank. However, the majority of the respondents agreed that financial and nonfinancial reward have a direct effect on employee motivation as well as organizational performance. Accordingly, the necessary conclusion was drawn and recommendation suggested for corrective action to be taken in the future by the Bank.

description: Fermion soliton stars are a motivated model of exotic compact objects in which a nonlinear self-interacting real scalar field couples to a fermion via a Yukawa term, giving rise to an effective fermion mass that depends on the fluid properties. Here we continue our investigation of this model within General Relativity by considering a scalar potential with generic asymmetric vacua. This case provides fermion soliton stars with a parametrically different scaling of the maximum mass relative to the model parameters, showing that the special case of symmetric vacua, in which we recover our previous results, requires fine tuning. In the more generic case studied here the mass and radius of a fermion soliton star are comparable to those of a neutron star for natural model parameters at the GeV scale. Finally, the asymmetric scalar potential inside the star can provide either a positive or a negative effective cosmological constant in the interior, being thus reminiscent of gravastars or anti-de Sitter bubbles, respectively. In the latter case we find the existence of multiple, disconnected, branches of solutions.

Curriculum Proximal Policy Optimization with Stage-Decaying Clipping for Self-Driving at Unsignalized Intersections

description: Unsignalized intersections are typically considered as one of the most representative and challenging scenarios for self-driving vehicles. To tackle autonomous driving problems in such scenarios, this paper proposes a curriculum proximal policy optimization (CPPO) framework with stage-decaying clipping. By adjusting the clipping parameter during different stages of training through proximal policy optimization (PPO), the vehicle can first rapidly search for an approximate optimal policy or its neighborhood with a large parameter, and then converges to the optimal policy with a small one. Particularly, the stage-based curriculum learning technology is incorporated into the proposed framework to improve the generalization performance and further accelerate the training process. Moreover, the reward function is specially designed in view of different curriculum settings. A series of comparative experiments are conducted in intersection-crossing scenarios with bi-lane carriageways to verify the effectiveness of the proposed CPPO method. The results show that the proposed approach demonstrates better adaptiveness to different dynamic and complex environments, as well as faster training speed over baseline methods.

General calculation of the cross section for dark matter annihilations into two photons

description: Assuming that the underlying model satisfies some general requirements such as renormalizability and CP conservation, we calculate the non-relativistic one-loop cross section for any self-conjugate dark matter particle annihilating into two photons. We accomplish this by carefully classifying all possible one-loop diagrams and, from them, reading off the dark matter interactions with the particles running in the loop. Our approach is general and leads to the same results found in the literature for popular dark matter candidates such as the neutralinos of the MSSM, minimal dark matter, inert Higgs and Kaluza-Klein dark matter.
