Consonant (De)gradation in Ingrian?
<p>This paper will present a dual method toward data enrichment for low-resource languages. Using Yoyodyne -- a Fairseq-inspired neural library for small-vocabulary sequence-to-sequence generation -- a morphological generation task was tested across labeled data encompassing multiple stages of …

Impact of Aggregate Gradation on Airfield (P-401) Asphalt Mixture
… Administrations' (FAA) current asphalt mixture gradation specification limits are finer, and the allowable ranges are more restrictive than control points for similar nominal maximum aggregate size mixtures within the Superpave mix design methodology. Ensuring the gradation specification limits …

Aggregate gradation impacts on fresh properties of 3D concrete printing mixtures
… framework exists to optimize aggregate gradation and paste volume, thereby reducing cement content, to meet targeted fresh property requirements for printability. This research study employed an experimental central composite design to quantify the effects of sand fineness and sand …

Application of layout and topology optimization using pattern gradation for the conceptual design of buildings
… constraints, in particular pattern gradation and repetition, in the context of layout optimization. By placing constraints on the design domain in terms of number and size of repeating patterns along any direction, the conceptual design for buildings is facilitated. To substantiate …

Optimizing the content and gradation of recycled tyre rubber particles to improve cracking resistance of concrete mortars
Concrete structures are designed to be sustained for a specific service life time. When some of these structures age, they undergo deterioration due to their exposure to harsh environmental conditions and thus their structural and aesthetic functionalities get compromised. In order to restore such …

Evaluation of ultrasound method for determining aggregate gradations in asphaltic concrete mixes
… method, ultrasound, to detect aggregate gradation differences in asphaltic concrete pavements. Empirical data had previously been used to suggest that the more coarse the gradation, the less incidence's of rutting. It is my thesis that the more coarse the gradation, the higher the …

“HERE THEY ARE IN THE LOWEST STATE OF SOCIAL GRADATION —ALIENS—POLITICAL—MORAL—SOCIAL ALIENS, STRANGERS, THOUGH NATIVES”: REMOVAL AND COLONIZATION IN THE OLD NORTHWEST, 1815-1870
… and Illinois traded in fears of racial degradation and national security as a means to generate fiscal support and positive public opinion for legislation and policies that attempted to create a white republic. Colonizationists appropriated imperial relocation solutions to the domestic …

Investigation of Coarse Aggregate Morphology Affecting Hot Mix Behavior Using Image Analysis
The coarse aggregate size, gradation and morphologies affect behaviors of asphalt mixes, however, the relationship is not yet well understood due to the lack of quantitative measurement of these important physical properties. Research work of this thesis aims at quantifying the size, gradation and …

Analysis of Fine Asphalt Concrete Mixture Gradations from Various Sources to Enhance Durability
… the durability of asphalt mixtures, is the gradation. This thesis will look into the effect of fine aggregate dense gradations on asphalt mixture durability for sources from the state of Nevada. Based on the available literature, finer gradation asphalt mixes have lower air void content and …

ANALYTICAL MODELING OF RUTTING POTENTIAL OF ASPHALT MIXES USING HAMBURG WHEEL TRACKING DEVICE
… is affected by AC temperature, mixture type, gradation, aggregate type, binder type and so on. There is no complete research in the literature which examined all these factors at the same time. This study evaluated the above mentioned factors in the deformation behavior of AC. Thin AC …

Asphalt Mixture Design Concepts to Develop Aggregate Interlock
… packing concepts to analyze the combined gradation and relate the packing characteristics to the mixture volumetric properties and compaction characteristics. The presented concepts include an examination of aggregate packing and aggregate interlock, blending aggregates by volume, a new …

Role of Aggregate Packing in Segregation Resistance and Flow Behavior of Self -Consolidating Concrete
… smaller aggregate size, continuous aggregate gradation, lower aggregate density, and higher paste viscosity and yield stress reduce dynamic segregation. Among these factors, aggregate size, gradation, density, and paste rheology have bigger effects than aggregate volume and initial concrete …

Investigating Use of Aggregate Density to Develop Design Aggregate Structure for Asphalt Concrete Mixtures
… Bailey Method was used to choose gradations and the selected research methodology supported the evaluation of the Bailey Method as a means for estimating changes in mix volumetric properties with changes to aggregate gradation. Aggregate density at various locking point …

Effects of maximum particle size and sample scaling on the mechanical behavior of mine waste rock; a critical state approach
… northwest of Elko, Nevada. The collected field gradation was scaled using the parallel gradation technique in order to most accurately reproduce the fabric of the collected field material in the laboratory. The two MWR materials were shown to have drastically different mineralogy, which may be …
