description: Purpose - The purpose of this work is to determine dependence of the separative power of the Iguassu gas centrifuge (GC) on the velocity of the rotor. Design/methodology/approach - The dependence is determined by means of computer simulation of the gas flow in the GC and numerical solution of the diffusion equation for the light component of the binary mixture of uranium isotopes. 2D axisymmetric model with the sources/sinks of the mass, angular momentum and energy reproducing the scoops was explored for the computer simulation. Parameters of the model correspond to the parameters of the so-called Iguassu centrifuge. The separative power has been optimised in relation to the pressure of the gas, temperature of the gas, the temperature drop along the rotor, power of the source of angularmomentum and energy, feed flow and geometry of the lower baffle. Findings - In the result, the optimised separative power depends only on the velocity, length and diameter of the rotor. The dependence on the velocity is described by the power law function with the power law index 2.6 which demonstrate stronger dependence on the velocity than it follows from experimental data. However, the separative power obtained with limitation on the pressure growth with the velocity depends on the velocity on the power similar to 2 which well agree with the experiments. Originality/value - For the first time, the optimised separative power of the GCs have been calculated via numerical simulation of the gas flow and diffusion of the binary mixture of isotope.

description: We show that nuclear motion of Rydberg atoms can be induced by resonant dipole-dipole interactions that trigger the energy transfer between two energetically close Rydberg states. How and if the atoms move depends on their initial arrangement as well as on the initial electronic excitation. Using a mixed quantum/classical propagation scheme we obtain the trajectories and kinetic energies of atoms, initially arranged in a regular chain and prepared in excitonic eigenstates. The influence of off-diagonal disorder on the motion of the atoms is examined and it is shown that irregularity in the arrangement of the atoms can lead to an acceleration of the nuclear dynamics.

description: The main objective of this article are two-fold. First, we introduce some general principles on phase transition dynamics, including a new dynamic transition classification scheme, and a Ginzburg-Landau theory for modeling equilibrium phase transitions. Second, apply the general principles and the recently developed dynamic transition theory to study dynamic phase transitions of PVT systems. In particular, we establish a new time-dependent Ginzburg-Landau model, whose dynamic transition analysis is carried out. It is worth pointing out that the new dynamic transition theory, along with the dynamic classification scheme and new time-dependent Ginzburg Landau models for equilibrium phase transitions can be used in other phase transition problems, including e.g. the ferromagnetism and superfluidity, which will be reported elsewhere. In addition, the analysis for the PVT system in this article leads to a few physical predications, which are otherwise unclear from the physical point of view.

description: In Carnegie Mellon University’s CyberScout project, we are developing mobile and stationary sentries capable of autonomous reconnaissance and surveillance. In this paper, we describe recent advances in the areas of efficient perception algorithms (detection, classification, and correspondence) and mission planning. In detection, we have achieved improved rejection of camera jitter and environmental variations (e.g., lighting, moving foliage) through multi-modal filtering, and we have implemented panoramic backgrounding through pseudo-real-time mosaicing. In classification, we present methods for discriminating between individuals, groups of individuals, and vehicles, and between individuals with and without backpacks. In correspondence, we describe an accurate multi-hypothesis approach based on both motion and appearance. Finally, in mission planning, we describe mapbuilding using multiple sensory cues and a computationally efficient decentralized planner for multiple platforms.
Predicting Mass Killings: Enhancing Theoretical Value of Models Through Complementary Techniques
Creators: name: Abbott, Rebecca
Publisher: name: University of Illinois at Chicago
Year: 2024

description: This dissertation attempts to improve accuracy and utility of forecasts of mass killings by proposing two ways in which forecasts can be reconnected to theory. The first solution offered is using Confirmatory Factor Analyses (CFA) to build measures of popular predictors in forecasts. The second solution is a demonstration of four post-hoc methods for extracting insights into black box machine learning models. Results indicate that these two solutions can improve forecast accuracy as well as utility to researchers by connecting forecasts to theorized constructs.

description: Snowlines are key ingredients for planet formation. Providing observational constraints on the locations of the major snowlines is therefore crucial for fully connecting planet compositions to their formation mechanism. Unfortunately, the most important snowline, that of water, is very difficult to observe directly in protoplanetary disks due to its close proximity to the central star. Based on chemical considerations, HCO$^+$ is predicted to be a good chemical tracer of the water snowline, because it is particularly abundant in dense clouds when water is frozen out. This work maps the optically thin isotopologue H$^{13}$CO$^+$ ($J=3-2$) toward the envelope of the low-mass protostar NGC1333-IRAS2A (observed with NOEMA at ~0.9" resolution), where the snowline is at larger distance from the star than in disks. The H$^{13}$CO$^+$ emission peaks ~2" northeast of the continuum peak, whereas the previously observed H$_2^{18}$O shows compact emission on source. Quantitative modeling shows that a decrease in H$^{13}$CO$^+$ abundance by at least a factor of six is needed in the inner ~360 AU to reproduce the observed emission profile. Chemical modeling predicts indeed a steep increase in HCO$^+$ just outside the water snowline; the 50% decrease in gaseous H$_2$O at the snowline is not enough to allow HCO$^+$ to be abundant. This places the water snowline at 225 AU, further away from the star than expected based on the 1D envelope temperature structure for NGC1333-IRAS2A. In contrast, DCO$^+$ observations show that the CO snowline is at the expected location, making an outburst scenario unlikely. The spatial anticorrelation of the H$^{13}$CO$^+$ and H$_2^{18}$O emission provide a proof of concept that H$^{13}$CO$^+$ can be used as a tracer of the water snowline.

description: We extend previous work on the minimal D-term inflation model modified by Right-Handed (RH) sneutrino fields to include additional inflaton-sector SUGRA corrections and two-field inflation effects. We show that SUGRA corrections simultaneously allow n_{s} to be within 3-year WMAP limits and the cosmic string contribution to the CMB power spectrum to be less than 5%. For gauge coupling g < 1, the CMB contribution from cosmic strings is predicted to be at least 1% while the spectral index is predicted to be less than 0.968 for a CMB string contribution less than 5%. Treating the inflaton-RH sneutrino system as a two-field inflation model, we show that the time-dependence of the RH sneutrino field strongly modifies the single-field results for values of RH sneutrino mass m_Φ > 0.1 H. The running spectral index is α= -0.0002 when m_Φ < 0.1 H but increases to positive values as m_Φ/H increases, with α> 0.008 for m_Φ > 1.0 H.

description: We analyse the dewetting of printing plates for gravure printing with well-defined gravure cells. The printing plates were mounted on a rotating horizontal cylinder that is half immersed in an aqueous solution of the anionic surfactant sodium 1-decanesulfonate. The gravure plates and the presence of surfactants serve as one example of a real-world dewetting situation. When rotating the cylinder, a liquid meniscus was partially drawn out of the liquid forming a dynamic contact angle at the contact line. The dynamic contact angle is decreased on a structured surface as compared to a smooth one. This is due to contact line pinning at the borders of the gravure cells. Additionally, surfactants tend to decrease the dynamic receding contact angle. We consider the interplay between these two effects. We compare the height differences of the meniscus on the structured and unstructured area as function of dewetting speeds. The height difference increases with increasing dewetting speed. With increasing size of the gravure cells this height difference and the induced changes in the dynamic contact angle increased. By adding surfactant, the height difference and the changes in the contact angle for the same surface decreased. We further note that although the liquid dewets the printing plates some liquid is always left in the gravure cell. At high enough surfactant concentrations or high enough dewetting speed, the dynamic contact angles in the structured surface approach those in flat surfaces. We conclude that surfactant reduces the influence of surface structure on dynamic dewetting.

Causal viscous hydrodynamics in 2+1 dimensions for relativistic heavy-ion collisions

Year: 2007

description: We explore the effects of shear viscosity on the hydrodynamic evolution and final hadron spectra of Cu+Cu collisions at ultrarelativistic collision energies, using the newly developed (2+1)-dimensional viscous hydrodynamic code VISH2+1. Based on the causal Israel-Stewart formalism, this code describes the transverse evolution of longitudinally boost-invariant systems without azimuthal symmetry around the beam direction. Shear viscosity is shown to decelerate the longitudinal and accelerate the transverse hydrodynamic expansion. For fixed initial conditions, this leads to a longer quark-gluon plasma (QGP) lifetime, larger radial flow in the final state, and flatter transverse momentum spectra for the emitted hadrons compared to ideal fluid dynamic simulations. We find that the elliptic flow coefficient v_2 is particularly sensitive to shear viscosity: even the lowest value allowed by the AdS/CFT conjecture, eta/s=1/4pi, suppresses v_2 enough to have significant consequences for the phenomenology of heavy-ion collisions at the Relativistic Heavy Ion Collider. A comparison between our numerical results and earlier analytic estimates of viscous effects within a blast-wave model parametrization of the expanding fireball at freeze-out reveals that the full dynamical theory leads to much tighter constraints for the specific shear viscosity eta/s, thereby supporting the notion that the quark-gluon plasma created at RHIC exhibits almost ``perfect fluidity''.

Starting from FRW spaces we specialize to a de Sitter spacetime and derive its inflationary power spectrum which we find to be almost flat. We finally investigate some consequences of requiring the existence of a unitary boundary conformal field theory in the framework of the dS/CFT correspondence.

description: We reconsider the Euclidean version of the photon number integral introduced in ref 1. This integral is well defined for any smooth non-self-intersecting curve in $\R^N$. Besides studying general features of this integral (including it s conformal invariance), we evaluate it explicitly for the ellipse. The result is $n_{ellipse}=(ξ^{-1}+ξ)π^2$, where $ξ$ is the ratio of the minor and major axes. This is in agreement with the previous result $n_{circle}=2π^2$ and also with the conjecture that the minimum value of $n$ for any plane curve occurs for the circle.

While in (In,Mn)Sb conventional Andreev reflection has been demonstrated, in (Ga,Mn)As quasiparticle density of states (DOS) broadening has been observed, possibly due to inelastic scattering effects. Here, we investigate the spin polarization, magnetic, and transport properties of epitaxially grown (Ga,Mn)Sb films with the Curie temperature of ~ 10K. The spin polarization of 57+/-5% was measured. Spectrum broadening in (Ga,Mn)Sb has also been observed.

description: We present a novel method for reconstructing the shape of an object from measured gradient data. A certain class of optical sensors does not measure the shape of an object, but its local slope. These sensors display several advantages, including high information efficiency, sensitivity, and robustness. For many applications, however, it is necessary to acquire the shape, which must be calculated from the slopes by numerical integration. Existing integration techniques show drawbacks that render them unusable in many cases. Our method is based on approximation employing radial basis functions. It can be applied to irregularly sampled, noisy, and incomplete data, and it reconstructs surfaces both locally and globally with high accuracy.

description: We explore the glassy dynamics of soft colloids using microgels and charged particles interacting by steric and screened Coulomb interactions, respectively. In the supercooled regime, the structural relaxation time $τ_α$ of both systems grows steeply with volume fraction, reminiscent of the behavior of colloidal hard spheres. Computer simulations confirm that the growth of $τ_α$ on approaching the glass transition is independent of particle softness. By contrast, softness becomes relevant at very large packing fractions when the system falls out of equilibrium. In this non-equilibrium regime, $τ_α$ depends surprisingly weakly on packing fraction and time correlation functions exhibit a compressed exponential decay consistent with stress-driven relaxation. The transition to this novel regime coincides with the onset of an anomalous decrease of local order with increasing density typical of ultrasoft systems. We propose that these peculiar dynamics results from the combination of the non-equilibrium aging dynamics expected in the glassy state and the tendency of colloids interacting through soft potentials to refluidize at high packing fractions.

Hydrologic Performance of Green Infrastructure across Climate Regions
Creators: name: Puengpapat, Peerawat
Publisher: name: University of Illinois at Chicago
Year: 2024

description: As a climate change adaptation strategy, numerous countries worldwide have implemented Green Infrastructure (GI) to attenuate the volume of stormwater runoff. The primary objective of this thesis is to compare the performance of seven GI types across six climate zones within the contiguous United States, categorized by the IPCC climate regions. The EPA Storm Water Management Model (SWMM) was used to simulate the following seven GI types: (1) bioretention cells, (2) infiltration trenches, (3) permeable pavement, (4) rain barrels, (5) vegetative swales, (6) rain gardens, and (7) green roofs. Additionally, the Python Stormwater Management Model (PySWMM) was incorporated into the analysis framework to conducte the simulations using a combination of random parameter values within a specified range that represents the characteristics of GI. The percentage of GI implementation was studied included runoff (m³) and peak flow rates (m³/s) at the catchment and outlet, respectively.
Permeable pavement performed best with a runoff volume reduction around 50% and a peak flow reduction of roughly 60%. Green roofs were effective in reducing runoff and lowering peak flow rates by approximately 30%. Bioretention cells and rain gardens ranked third, reducing runoff volume by about 24% and lowering peak flow rates by approximately 22%. Infiltration trenches came next, reducing runoff volume by about 22% and peak flow rates by 20%. Rain barrels and vegetative swales were seldom effective. Vegetative swales reduced peak flow by 15% but had minimal impact on volume, decreasing it by less than 1%. Rain barrels were similarly ineffective, with reductions of less than 3% for both performance metrics.
The effectiveness of GI is significantly influenced by the climatic characteristics of a region. For permeable pavement and green roofs, their performance declines notably in moist regions, with the order of performance as follows: Cool temperature regions outperform warm temperature regions, and warm regions outperform tropical regions. Vegetative swales consistently exhibit inferior performance in the tropical and moist (TM) region. In contrast, the overall results for bioretention cells, infiltration trenches, rain barrels, and rain gardens do not exhibit significant changes across various climate regions.

description: Long Gamma Ray Bursts (GRBs) constitute an important tool to study the Universe near and beyond the epoch of reionization. We delineate here the characteristics of an 'ideal' instrument for the search of GRBs at z>6-10. We find that the detection of these objects requires soft band detectors with a high sensitivity and moderately large FOV. In the light of these results, we compare available and planned GRB missions, deriving conservative predictions on the number of high-z GRBs detectable by these instruments along with the maximum accessible redshift. We show that the Swift satellite will be able to detect various GRBs at z>6, and likely at z>10 if the trigger threshold is decreased by a factor of ~2. Furthermore, we find that INTEGRAL and GLAST are not the best tool to detect bursts at z>6: the former being limited by the small FOV, and the latter by its hard energy band and relatively low sensitivity. Finally, future missions (SVOM, EDGE, but in particular EXIST) will provide a good sample of GRBs at z>6 in a few years of operation.

Real-Time Scheduling of Sensor-Based Control Systems

description: Many sensor-based control systems are dynamically changing, and thus require a flexible scheduler. The rate monotonic (RM) real-time scheduling algorithm does not support such dynamic systems very well. On the other hand, with earliest-deadline-first (EDF) and minimum-laxity-first (MLF) dynamic scheduling algorithms, a transient overload in the system may cause a critical task to fail, which is certainly undesirable. This paper proposes a new real-time scheduling algorithm, which we call maximum-urgency-first (MUF), which combines the advantages of the RM, EDF, and MLF algorithms. Like EDF and MLF, MUF has a schedulable bound of 100% for the critical set. And like RM, a critical set can be defined that is guaranteed to meet all its deadlines. The MUF algorithm also allows the scheduler to detect three forms of deadline failures, and call failure handler routines for tasks which fail to meet their deadlines.The MUF scheduler has been implemented as the default scheduler of CHIMERA II, a real-time operating system being used to control sensor-based control systems both at Carnegie Mellon University and elsewhere. There are still many issues to be addressed with regards to the MUF algorithm. This paper also presents those issues, with possible approaches that should be investigated further.

description: Extensions of the MSSM generically feature gauge singlet Higgs bosons. These singlet Higgs bosons have tan(beta)-enhanced Yukawa couplings to down-type quarks and leptons at the one-loop level. We present an effective Lagrangian incorporating these Yukawa couplings and use it to study their effect on singlet Higgs boson phenomenology within both the mnSSM and NMSSM. It is found that the loop-induced couplings represent an appreciable effect for the singlet pseudoscalar in particular, and may dominate its decay modes in some regions of parameter space.

description: We present a new Python library called vaex, to handle extremely large tabular datasets, such as astronomical catalogues like the Gaia catalogue, N-body simulations or any other regular datasets which can be structured in rows and columns. Fast computations of statistics on regular N-dimensional grids allows analysis and visualization in the order of a billion rows per second. We use streaming algorithms, memory mapped files and a zero memory copy policy to allow exploration of datasets larger than memory, e.g. out-of-core algorithms. Vaex allows arbitrary (mathematical) transformations using normal Python expressions and (a subset of) numpy functions which are lazily evaluated and computed when needed in small chunks, which avoids wasting of RAM. Boolean expressions (which are also lazily evaluated) can be used to explore subsets of the data, which we call selections. Vaex uses a similar DataFrame API as Pandas, a very popular library, which helps migration from Pandas. Visualization is one of the key points of vaex, and is done using binned statistics in 1d (e.g. histogram), in 2d (e.g. 2d histograms with colormapping) and 3d (using volume rendering). Vaex is split in in several packages: vaex-core for the computational part, vaex-viz for visualization mostly based on matplotlib, vaex-jupyter for visualization in the Jupyter notebook/lab based in IPyWidgets, vaex-server for the (optional) client-server communication, vaex-ui for the Qt based interface, vaex-hdf5 for hdf5 based memory mapped storage, vaex-astro for astronomy related selections, transformations and memory mapped (column based) fits storage. Vaex is open source and available under MIT license on github, documentation and other information can be found on the main website: https://vaex.io, https://docs.vaex.io or https://github.com/maartenbreddels/vaex

As an example, we show that left- and right-handed chiral molecules starting in the same initial states can evolve into different final states by a purely dynamic transfer process. That means, left- and right-handed molecules can be distinguished purely dynamically.

description: Charge transfer (or exchange) reactions between hydrogen atoms and protons in collisionless shocks of supernova remnants (SNRs) are a natural way of producing broad Balmer, Lyman and other lines of hydrogen. We wish to quantify the importance of shock-induced, non-thermal hydrogen emission from SNRs in young galaxies. We present a method to estimate the luminosity of broad ($\sim 1000$ km s$^{-1}$) Ly$α$, Ly$β$, Ly$γ$, H$β$ and P$α$ lines, as well as the broad and narrow luminosities of the two-photon (2$γ$) continuum, from existing measurements of the H$α$ flux. The expected broad Ly$α$ luminosity per object is at most $\sim 10^{36}$ erg s$^{-1}$. In principle, broad, ``non-radiative'' Ly$α$ from SNRs in young galaxies can be directly observed in the optical range of wavelengths. However, by taking into consideration the different rates between core collapse and thermonuclear supernovae, as well as the duration we expect to observe such Ly$α$ emission from SNRs, we expect their contribution to the total Ly$α$ luminosity from $z \sim 3$ to 5 galaxies to be negligibly small ($\sim 0.001 %$), compared to the radiative shock mechanism described by Shull & Silk (1979). Though broad, non-thermal Ly$α$ emission has never been observed, these photons are produced in SNRs and hence the non-radiative Ly$α$ luminosity is a part of the intrinsic Ly$α$ spectrum of young galaxies.

Prevalence of Chronic Kidney Disease of Undetermined Causes (CKDu) in a Sugarcane Growing Region of Kenya

description: Background: Epidemics of chronic kidney disease of undetermined causes (CKDu) among young male agricultural workers have been observed in many tropical regions. Western Kenya has similar climatic and occupational characteristics as many of those areas. The study objectives were to characterize prevalence and predictors of CKDu, such as, HIV, a known cause of CKD, in a sugarcane growing region of Kenya; to estimate prevalence of reduced estimated glomerular filtration rate (eGFR) and CKDu across occupational categories and to evaluate if physically demanding work or sugarcane work are associated with reduced eGFR. The third objective was to assess the association between eGFR based on the Household Water Insecurity Experiences (HWISE) Scale and urine specific gravity, a crude indicator of hydration status.

Methods: The Disadvantaged Populations eGFR Epidemiology Study (DEGREE) protocol was followed in a cross-sectional study conducted in Kisumu County, Western Kenya. Multivariate logistic regression was performed to identify predictors of reduced eGFR.

Results: Among 782 adults the prevalence of eGFR <90 was 9.85%. Among the 612 participants without diabetes, hypertension, and heavy proteinuria the prevalence of eGFR <90 was 8.99% (95%CI 6.8%, 11.5%) and 0.33% (95%CI 0.04%, 1.2%) had eGFR <60. Among the 508 participants without known risk factors for reduced eGFR (including HIV), the prevalence of eGFR <90 was 5.12% (95%CI 3.4%, 7.4%); none had eGFR <60. Significant risk factors for reduced eGFR were sublocation, age, body mass index, and HIV. No association was found between reduced eGFR and work in the sugarcane industry, as a cane cutter, or in physically demanding occupations. Urine specific gravity (dehydration) and the Household Water Insecurity Experiences (HWISE) Scale were not associated with reduced eGFR, but water insecure households determined from the HWISE Scale, were significantly associated with urine specific gravity ≥1.020 (dehydrated) in an unadjusted model.

Conclusion: CKDu is not a common public health problem in this population, and possibly this region. We recommend that future studies should consider HIV to be a known cause of reduced eGFR. Factors other than equatorial climate and work in agriculture may be important determinants of CKDu epidemics.

description: We find that the heat capacity of a strongly correlated metal presents striking changes with respect to Landau Fermi liquid theory. In contrast with normal metals, where the electronic specific heat is linear at low temperature (with a T^3 term as a leading correction), a dynamical mean-field study of the correlated Hubbard model reveals a clear kink in the temperature dependence, marking a rapid change from a low-temperature linear behavior and a second linear regime with a reduced slope. Experiments on LiV2O4 support our findings, implying that correlated materials are more resistive to cooling at low T than expected from the intermediate temperature behavior.

description: Abstract

Objectives- The main objectives of the study are to translate and explore the factor structure of Sports Anxiety Scale (SAS-2) as well as to compare the multidimensional sports anxiety of participants on the basis of their gender. Method-This research is consisted of two studies. In the first study SAS-2 was translated in Urdu language. In the second study Exploratory Factor Analysis was run on a data set collected from 437 athlete adolescents whereas for Confirmatory Factor Analysis 525 participants were selected conveniently. Results- Urdu version reached up to acceptable levels of internal consistency (α=0.92) cross language validation and factorial validity. EFA showed 3-factor structure named as Somatic, Worry and Concentration Disruption and further this structure was confirmed by CFA showing good model fit χ2 (96) = 293.81, p < .001, NFI = .92, CFI = .98, GFI = .95, RMSEA = .05).  Girls athlete exhibited higher levels of Somatic, worry and Concentration-Disruption Anxiety as compared to their boys counterparts. Conclusion- The results showed that Urdu translated version of SAS-2 for Pakistani adolescents is a reliable and valid measure however the scale needs further validation.

description: The timing of sensor-based control systems is crucial. Critical servo-level periodic tasks that fail to meet their deadlines result in losing data or missing control cycles. This can lead to a loss in performance in the best case, and can cause serious damage to equipment or human injury in the worst case. It is therefore critical that the timing of these systems is predictable and controllable. A dynamically reconfigurable system can change in time without the need to halt the system. Such systems may have many sensors or actuators, only a subset of which are used at any time. Alternately the same hardware is used in a different configuration. In this paper we propose the maximum-urgency-first algorithm, which can be used to predictably schedule dynamically changing systems. We show that it is a significant improvement over the rate monotonic algorithm, which can only be used to schedule static systems. The maximum-urgency-first scheduler has been implemented as the default scheduler of CHIMERA II, a real-time operating system being used to control sensor-based control systems both at Carnegie Mellon University and elsewhere.
Crossing the phantom divide in an interacting generalized Chaplygin gas

description: Unified generalized Chaplygin gas models assuming an interaction between dark energy and dark matter fluids have been previously proposed. Following these ideas, we consider a particular relation between dark densities, which allows the possibility of a time varying equation of state for dark energy that crosses the phantom divide at a recent epoch. Moreover, these densities decay during all the evolution of the Universe, avoiding a Big Rip. We find also a scaling solution, i.e. these densities are asymptotically proportional in the future, which contributes to the solution of the coincidence problem.

description: By examining asymptotic behavior of certain infinite basic ($q$-) hypergeometric sums at roots of unity (that is, at a "$q$-microscopic" level) we prove polynomial congruences for their truncations. The latter reduce to non-trivial (super)congruences for truncated ordinary hypergeometric sums, which have been observed numerically and proven rarely. A typical example includes derivation, from a $q$-analogue of Ramanujan's formula $$ \sum_{n=0}^\infty\frac{\binom{4n}{2n}{\binom{2n}{n}}^2}{2^{8n}3^{2n}}\,(8n+1) =\frac{2\sqrt{3}}π, $$ of the two supercongruences $$ S(p-1)\equiv p\biggl(\frac{-3}p\biggr)\pmod{p^3} \quad\text{and}\quad S\Bigl(\frac{p-1}2\Bigr) \equiv p\biggl(\frac{-3}p\biggr)\pmod{p^3}, $$ valid for all primes $p>3$, where $S(N)$ denotes the truncation of the infinite sum at the $N$-th place and $(\frac{-3}{\cdot})$ stands for the quadratic character modulo $3$.

description: This paper presents a new formulation of the artificial potential approach to the obstacle avoidance problem for a mobile robot or a manipulator in a known environment. Previous formulations of artificial potentials, for obstacle avoidance, have exhibited local minima in a cluttered environment. To build an artificial potential field, we use harmonic functions which completely eliminate local minima even for a cluttered environment. We use the panel method to represent arbitrarily shaped obstacles and to derive the potential over the whole space. Based on this potential function, we propose an elegant conml strategy for the real-time control of a robot. We test the harmonic potential, the panel method and the control strategy with a bar-shaped mobile robot and a 3 dof planar redundant manipulator.
