Grounding robot motion in natural language and visual perception

Bronikowski, Scott Alan PhD, Purdue University, May 2016. Grounding Robot Motion in Natural Language and Visual Perception. Major Professor: Jeffrey Mark Siskind. The current state of the art in military and first responder ground robots involves heavy physical and cognitive burdens on the human operator while taking little to no advantage of the potential autonomy of robotic technology. The robots currently in use are rugged remote-controlled vehicles. Their interaction modalities, usually utilizing a game controller connected to a computer, require a dedicated operator who has limited capacity for other tasks. I present research which aims to ease these burdens by incorporating multiple modes of robotic sensing into a system which allows humans to interact with robots through a natural-language interface. I conduct this research on a custom-built six-wheeled mobile robot. First I present a unified framework which supports grounding natural-language semantics in robotic driving. This framework supports learning the meanings of nouns and prepositions from sentential descriptions of paths driven by the robot, as well as using such meanings to both generate a sentential description of a path and perform automated driving of a path specified in natural language. One limitation of this framework is that it requires as input the locations of the (initially nameless) objects in the floor plan. Next I present a method to automatically detect, localize, and label objects in the robot’s environment using only the robot’s video feed and corresponding odometry. This method produces a map of the robot’s environment in which objects are differentiated by abstract class labels. Finally, I present work that unifies the previous two approaches. This method detects, localizes, and labels objects, as the previous method does. However, this new method
Broadband adoption in Latin American countries: does geographic proximity matter?

This paper analyzes whether geographic proximity among countries can be a significant factor in explaining fixed and mobile broadband adoption in Latin America. To address the research question if neighbor effects could impact on the broadband penetration of a country, we estimate a Spatial Durbin panel data model over the period 2011-2015, for 18 Latin American countries. Results obtained suggest a significant spatial effect of the broadband penetration. In particular, results show positive spatial effects for fixed broadband (confirming previous studies in Europe) but negative spatial effects for mobile broadband adoption.
Improvements in the GISTEMP Uncertainty Model

We outline a new and improved uncertainty analysis for the Goddard Institute for Space Studies Surface Temperature product version 4 (GISTEMP v4). Historical spatial variations in surface temperature anomalies are derived from historical weather station data and ocean data from ships, buoys, and other sensors. Uncertainties arise from measurement uncertainty, changes in spatial coverage of the station record, and systematic biases due to technology shifts and land cover changes. Previously published uncertainty estimates for GISTEMP included only the effect of incomplete station coverage. Here, we update this term using currently available spatial distributions of source data, state‐of‐the‐art reanalyses, and incorporate independently derived estimates for ocean data processing, station homogenization, and other structural biases. The resulting 95% uncertainties are near 0.05 °C in the global annual mean for the last 50 years and increase going back further in time reaching 0.15 °C in 1880. In addition, we quantify the benefits and inherent uncertainty due to the GISTEMP interpolation and averaging method. We use the total uncertainties to estimate the probability for each record year in the GISTEMP to actually be the true record year (to that date) and conclude with 87% likelihood that 2016 was indeed the hottest year of the instrumental period (so far).
Preliminary Report of Light Pollution in Indonesia Based on Sky Quality Observation

We observed night sky quality in several LAPAN stations (Agam, Bandung, Pontianak, Sumedang, Garut, Pasuruan, and Biak) which were conducted from April until July 2018 using Unihedron Sky Quality Meter LU-DL type. Observational data from all of the observational points were then sent regularly to a centralized database for further use. Although most of the measurements were done in overcast conditions, we were able to determine the representative clear sky brightness statistically. The results showed that the light pollution level of the most of the stations are moderate (the values at Biak, Agam, Sumedang, and Pontianak are 20.0, 19.5, 19.6, and 17.7 mpsas respectively) and the stations which are located near or in cities are high (Bandung and Pasuruan with 17.1 and 18.0 mpsas, respectively). In a particular station (Garut) the light pollution is low (20.6 mpsas), so it is good to make this spot to be a location of astrotourism.
Determinants of Distribution of Large Mammals in Seti River Basin, Tanahun District of Western Nepal

Forest landscape in Seti River basin of Western Nepal is not conserved within the protected area network. Wildlife habitats in Seti River basin are more vulnerable due to high anthropogenic disturbance and habitat fragmentation. Present study mainly focused to evaluate the major factors that determine the distribution of large mammals in Seti River basin by walking through 34 line transects that covered a total of 59.89 km. The distribution of large mammals was greatly affected by habitat types, human disturbances, topography and altitude. Himalayan gorals were recorded in the steep grass covered areas where as Muntjacs were found in most of the habitats and slopes. There was low occurrence of all species nearer to the settlements and roads. Besides, water sources played a vital role in distribution of wildlife, as there were more occurrences of signs of large mammals nearby water resources. In the study area, community forests played a major role in the conservation of viable population of large mammals. However, habitat fragmentation due to scattered human settlements and degradation of foraging grounds such as grasslands by succession and invasion of alien plant species added more threats to the survival of large mammals. Therefore, such situation can be improved through the protection of connecting forest patches and scientific management of forests and grasslands.
Note on the Amphibians and Reptiles of the Mungbwalu (Ituri Province) and Mutwanga (Province of North-Kivu) in DRC

The Democratic Republic of Congo's forests are rich and diversified in biodiversity, particularly in high-altitude regions where they are reputed to be very rich in animal and plant biological diversity, particularly amphibians. Nevertheless, this fauna has not been well documented so far, mainly because of the lack of expertise in this field in the DRC. To contribute to this area, an inventory of amphibians and reptiles had been carried out in the Ituri forest and Mutwanga. We note that the herpetofauna of this region has never been the subject of a recent and thorough study. In order to analyse its biodiversity, 4 sites far from each other, all located in the primary forest, had been sampled. To achieve this, data collection was carried out during the dry season from 25 December 2014 to 12 January 2015 (18 days). The prospecting of the sites took place day and night in view and during the hearing. Amphibians and reptiles had been caught by hand and with the snake stick. All specimens had been digitized, fixed in formaldehyde (10%) and then preserved in alcohol (70%). Muscle necropsies were preserved in Eppendorf tubes containing absolute alcohol (96%). In total, 182 amphibian specimens divided into 32 species, 4 families, all belonging to the Order of the Anurans and 37 reptile specimens diversified into 18 species, 7 families and grouped into two Orders were recorded. The species capture: Hymenochirus boulengeri, Hyperolius rossii, Amietia desaegeri, Amietia ruwenzorica, Xenopus lenduensis and Xenopus ruwenzoriensis were interesting because these species remain poorly documented in the region.

Spatial and Temporal Evolution of Low Water Flows in the Sassandra River Catchment Area in Cote d’Ivoire

In a context of climate change and declining water resources, knowledge of low flow is essential. Present study deals with the spatial and temporal evolution of the streams low flow in Sassandra river. In the study, 12 stations of the Sassandra sub-basins (Sassandra, N’zo, Lobo, and Davo) were selected according to the availability and quality of long-term data. Annual, monthly and daily low flow data from twelve hydrological stations of the Sassandra watershed were used and cover the period from 1970 to 2015. The methodology used is concerned with extracting the low flow data and analyzing and evaluating the trends (Mann-Kendall) and change-point (cumulate sum) of low flow data. Statistical tests are applied to the mean and variance of the low-flow series. The results of the statistical tests show more trends and change points on the mean than on the variance. Significant trends show an increase in low flow waters. The significant change point detected by the cumulative sums test generally occurs between 1990-2007. In addition, tributaries are more affected by significant trends and change point detection than Sassandra river.
Chirp-type solutions to Schrödinger Equations

In this thesis, we focus on the search of solutions to the Schrodinger Equation that are, for any fixed time, the so-called "chirp" functions. Namely, we look for explict solutions, which take the form of superposition of "chirps", to both the homogeneous and the non-homogeneus Cauchy Problem for the Free Particle Schrodinger Equation and the Quantum Harmonic Oscillator Schrodinger Equation, as well. We point out that the proofs of our results, just based on classical differential calculus, perfecty match with the latest ones on the propagation of the Gabor wave front set for the Schrodinger Equation, founded on Pseudo-differential Theory.

A comparison of radio capture models and their effect on wireless LAN protocols

Examines the effect of radio capture on the performance of radio frequency wireless local area networks (LANs). In many wireless LANs, multiple remote stations may simultaneously attempt to transmit data packets. Due to the capture effect, differences in received power levels can result in the successful reception of a packet in the presence of contending transmissions. The authors compare several types of radio capture models and investigate their effects on the slotted Aloha protocol, which is a component protocol of more complex multiple access protocols that are used in wireless LANs. Specifically, they analyse a vulnerability circle capture model as well as a more detailed model that includes the cumulative effect of the interference power generated by multiple contending remote stations. The effects of Rayleigh fading, shadowing, and different spatial distributions of remote stations are also considered. <<ETX>>
The Impact of Biological Bedforms on Near‐Bed and Subsurface Flow: A Laboratory‐Evaluated Numerical Study of Flow in the Vicinity of Pits and Mounds

The complex surface topography of river substrates controls near‐bed hydraulics and drives the exchange of subsurface and surface flow. In rivers, the topographic structures that are studied are usually formed by the flow, but it is known that many animals also create biogenic bedforms, such as pits and mounds. Here, a large‐eddy simulation model of flow over a pit and a mound is evaluated with flume experiments. The model includes actual bedform topography, and the topographic complexity of the surrounding bed surface. Subsurface grains are organized in a body‐centered cubic packing arrangement. Model evaluation showed strong agreement between experimental and modeling results for velocity (R2 > 0.8) and good agreement for Reynolds stresses (R2 > 0.7), which is comparable to other similar studies. Simulation of the pit shows that the length of the downwelling region is smaller than the upwelling region and that the velocity magnitude is higher in the downwelling region. Simulation of the mound reveals that the flow is forced into the bed upstream of the mound and reemerges near the top of the mound. The recirculation zone is limited at the leeside of the mound. With increasing Reynolds number, the depth of the upwelling region at the leeside of the mound increases. The analysis of shear stress indicates that sediments on the upstream edge of the pit and on the downstream face of the mound are relatively unstable. These results demonstrate the effect of biogenic structures on the near‐bed flow field, hyporheic exchange, and sediment stability.
Microbiological Quality Assessment of Commercially and Laboratory Prepared Orange Juice

Orange juice has become one of the most widely accepted natural beverages due to its invigorating flavours, source of quick energy in the form of natural sugars and its nutrient which support the growth of acid tolerant bacteria, yeasts and moulds. Present investigation was conducted to study the microbiological examination of commercially and freshly prepared orange juices. Freshly prepared orange juices were pasteurised, carbonated, concentrated and chemically treated with a preservative (sodium metabisulphite) and stored under, freezer, refrigeration and ambient temperature for 90 days. The pH ranged from 3.0 to 4.5 for the commercially, fresh and stored samples respectively. The total bacterial load ranged from 1.6x105 to 3.6x106 and the total yeast cell counts ranged from 1.7x104 to 4.8x106 cfu/ml for the commercially, freshly and stored samples. Twenty-two microbial species including 5 bacterial isolates, 6 yeast isolates and 11 isolates of mould were isolated from the orange juices. The bacterial isolates identified from the samples were Bacillus megaterium, Bacillus cereus, Bacillus pantothenticus, Bacillus aeruginosa and Escherichia coli. The fungal isolates were Saccharomyces cerevisiae, Saccharomyces rouxii, Saccharomyces telluris, Blastomyces sp, Aspergillus sp, Mycelia sp, Chrysosporium sp, and Trichoderma sp. Among the bacterial isolates, Bacillus sp was the predominant, while the fungi Saccharomyces sp and Mycelia sp were the predominant fungi and accounted for five out of 11 isolates. The isolates of bacteria, yeasts and moulds appear to be persistent throughout the period of this study and could be used as indicators of microbial quality. A safe microbial load and reduction in contamination of orange juice /fruit juices can be achieved by combination of processing methods such as chemical preservatives with pasteurisation,concentration with carbonation under controlled microbiological environments such as freezer and refrigeration temperatures.
Understanding the effects of grazing and prescribed fire on hydrology of Kentucky bluegrass–dominated rangelands in the northern Great Plains

According to National Resources Inventory data, Kentucky bluegrass (Poa pratensis L.) is now present in over 85% of the areas sampled. This invasive, perennial, cool season grass can serve to stabilize soils and increase site stability; however, it also alters nutrient flows, soil structure, and plant community composition, ultimately degrading biotic integrity. In addition, Kentucky bluegrass alters the hydrologic function of an area by changing root structure and the way in which water flow is captured and released back into the ecosystem. To clarify the effect of Kentucky bluegrass on hydrological characteristics of invaded sites, rainfall simulation experiments and hydrophobicity measurements with water drop infiltration time and molarity of ethanol droplet tests were conducted at three locations all within the same ecological site in the northern Great Plains. Rainfall simulation experiments were performed on 24 large plots (6 × 2 m) at 63.5 mm h−1 and 127 mm h−1 intensities and on 16 small plots (0.7 × 0.7 m) at 63.5 mm h−1 and 103 mm h−1. Rainfall was maintained on the large plots until 10 minutes of steady-state runoff was measured or for a maximum of 30 minutes in the absence of runoff, while on the small plots, rainfall duration was set at 25 minutes. The soil layer was divided into four strata (litter, thatch, root mat, and mineral soil), which were physically separated for their hydrophobic behavior in laboratory and field water drop penetration tests and molarity analyses. Our results indicate that on dry soil strata, water drop penetration time increased by 20 seconds on litter and 3 seconds on thatch for every percentage point increase in Kentucky bluegrass in the vegetation, confirming the close association between this grass species and the development of soil hydrophobicity. Rainfall simulation on dry soils (less than 20% volumetric water content) also revealed that the time needed to initiate runoff was shortened by 5 minutes, and the runoff ratio increased by 0.004 for every percentage point increase of Kentucky bluegrass in the vegetation cover. Hydrophobicity dramatically declined in the thatch layer by a factor of 4 and was completely absent from the litter layer after wetting. In contrast to the rainfall simulations on dry soils, wet runs (volumetric water content ≥20%) showed a beneficial effect of Kentucky bluegrass on hydrologic response with delayed runoff by 5 minutes and reduced runoff ratios by 0.003 for 1% increase in Kentucky bluegrass in the vegetation cover. Prescribed fire increased litter hydrophobicity, but this did not adversely affect hydrologic response. This study highlights the need for further research contrasting detrimental effects of Kentucky bluegrass on hydrologic response in dry soil conditions with the beneficial effect of this grass on infiltration under wet conditions to better predict the overall ecohydrological outcome of an invasion by this grass species.

Laboratory Study of the Geotechnical Properties of Abraded Railway Ballast with Natural and Clay Mix Fouling

LABORATORY STUDY OF THE GEOTECHNICAL PROPERTIES OF ABRADED RAILWAY BALLAST WITH NATURAL AND CLAY MIX FOULING MAY 2019 ANDREW ROHRMAN, B.S., NORTHEASTERN UNIVERSITY M.S., UNIVERSITY OF MASSACHUSETTS AMHERST Ph.D., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor Carlton L. Ho With 140,000 miles of active track, railroad freight is the largest method of transporting goods in the United States. An important component of the railroad substructure is the gravel-size aggregate placed below the tracks, called ballast. The ballast is responsible for draining water away from the track, resisting forces from traffic loading, maintaining track position, and reducing loads to acceptable pressures for the subgrade. Ballast is typically selected to be highly angular and uniformly graded, but these characteristics are constantly changing under dynamic traffic loading. As the ballast is loaded, the particles abrade against each other, grinding off stone dust and breaking off larger corners. This process reduces the angularity of ballast and also contributes to fouling, which is finer grained materials entering the voids of the ballast. Fouling generally reduces the strength of ballast, particularly when water is present, as it prevents the water from draining away from the track. This study aims to better understand the influence of both fouling content and ballast particle angularity on the strength properties and deformation characteristics of ballast. This is achieved through a series of laboratory tests using ballasts of different angularity and different fouling types, from which the results are directly compared to one another. Additionally, to better understand the particle packing structure of ballast-fouling mixtures, a series of minimum and maximum density tests have been performed on
