Abstract:

AbstractWe present the first VLBA maps of Galactic H ɪ opacity towards the QSO 3C 138. The maps show significant opacity structure down to angular scales of 20 mas, which implies density structures in the cold neutral medium on physical scales of 10 AU or less

Abstract:

Clark & Thornton (C&T) have demonstrated the paradox between the opacity of the transformations that underlie relational mappings and the ease with which people learn such mappings. However, C&T's trading-spaces proposal resolves the paradox only in the broadest outline. The general-purpose algorithm promised by C&T remains to be developed. The strategy of doing so is to analyze and formulate computational mechanisms for known cases of recoding.

Abstract:

Thermal inertia, which represents the resistance to change in temperature of the upper few centimeters of the surface, provides information to help understand the surficial geology and recent processes that are potentially still active today. It cannot be directly measured on Mars and is therefore usually modelled. We present a new analytical method based on Apparent Thermal Inertia (ATI), a thermal inertia proxy. Calculating ATI requires readily available input data: temperature, incidence angle, visible dust opacity, and a digital elevation model. Because of the high spatial resolution, the method can be used on sloping terrains, which makes possible thermal mapping using THEMIS in nearly any area of Mars. Comparison with results obtained by other approaches using modeled data shows similarity in flat areas and illustrates the significant influence of slope and aspect on albedo and diurnal temperature differences.

Abstract:

Located at the heart of the University of South Carolina campus is the historic Horseshoe—originally the South Carolina College campus (est. 1801)—a site whose construction during the antebellum years relied on enslaved labor. Ghosts of the Horseshoe is a cross-College, collaborative “critical interactive” for iPad that features the Horseshoe campus and endeavors to make visible this unacknowledged history. The application uses as its dedicated navigational interface a historic 1884 Sanborn Fire Insurance map of the site; participants can also activate a Google Map overlay of the site and determine its degree of opacity with respect to the archival map image. Importantly, however, the two maps do not actually “map” onto each other. This serves as a first mis-mapping of several mis-mappings. This article considers how such mis-mappings, involving geo-locative contingencies, representational disjunctions, and potential dis-locations, mediate site-specific explorations and, as such, make possible alternative historiographic understandings of place.

Abstract:

This chapter concludes, summarizing key findings concerning prosodic weight and raising issues for further research. It compares three approaches to weight-sensitivity in phonology, namely, categorical mapping constraints (such as WEIGHT-TO-STRESS), phonetic discriminant analysis (which identifies optimal criteria), and direct phonetics–phonology interface approaches (such as $t$-to-Stress, where $t$ is a numerical weight percept). Advantages and pathologies of each approach are discussed, pointing towards a possible eventual synthesis. The chapter also includes sections treating the opacity of weight criteria, the domain of the weight percept (which is argued to include parts of onsets by way of p-centers), and the varying degrees of categoricity vs. gradience found in different types of phenomena, where the incidence of gradience tends to correlate with domain size.

Abstract:

The opacity of AI systems' decision making has led to calls to modify these systems so they can provide explanations for their decisions. This chapter contains a discussion of what these explanations should address and what their nature should be to meet the concerns that have been raised and to prove satisfactory to users. More specifically, the chapter briefly reviews the typical forms of AI decision-making that are currently used to make real-world decisions affecting people's lives. Based on concerns about AI decision making expressed in the literature and the media, the chapter follows with principles that the systems should respect and corresponding requirements for explanations to respect those principles. A mapping between those explanation requirements and the types of explanations generated by AI decision making systems reveals the strengths and shortcomings of the explanations generated by those systems.

Abstract:

Colors are described by three components RGB and alpha component. This component adds additional realism in the computer scene and means opacity. Alpha mapping is a process that regulates objects transparency. This is an often used and successful process. This effect is rather simple. The realization requires few and simple resources. Such modern graphics libraries as DirectX, OpenGL and WebGL have powerful opportunities to implement a light mapping. For the realization we can use powerful graphical library DirectX and OpenGL. There is also an opportunity to use the graphic library for the internet WebGL.

Abstract:

The Improved Stratospheric and Mesospheric Sounder (ISAMS) is a limb-viewing infrared radiometer which measures thermal emission in 24 spectral bands, using both wideband (WB) and pressure modulator radiometer (PMR) techniques (Taylor, 1983). This enables the daily mapping over much of the Earth of temperature, the concentrations of 8 chemical species (water vapour, methane, ozone, nitric acid, nitrogen dioxide, nitric oxide, dinitrogen pentoxide, carbon monoxide) and aerosol opacity in the stratosphere and mesosphere. The instrument has eight separate focal planes, each consisting of a 4-element detector array, which are cooled by two mechanical coolers.

Abstract:

Abstract The measurement of particle plume and curtain temperatures in particle-laden gravity-driven flows presents a unique challenge to thermometry due to the flow’s transient and stochastic nature. Earlier attempts to assess the bulk particle temperature of a plume using intrusive and non-intrusive methods have produced very limited success. Here we describe a non-intrusive method using a high-speed IR camera (ImageI8300 from Infratec) and a visible-light camera (Nikon D3500) to produce indirect particle temperature measurements. The IR camera produces thermogram sets mapping the apparent particle temperature, while the visible-light image sets allow for the calculation of the plume opacity as a function of flow discharge position. An in-house post-processing algorithm based on Planck’s radiation theory was developed to compute the true particle temperature which is a function of the apparent temperature (thermograms) and the plume opacity obtained from the visible-light images. To validate these results, a series of lab-scale tests generating particle curtains of known dimensions at various temperatures were performed. The lab-scale tests were conducted using a small particle receiver which is equipped with thermocouples to measure the temperature directly. Using the recorded thermocouple data, a particle temperature function can be derived empirically, based on the lumped capacitance model for a free-falling sphere. The empirical particle temperature function is then compared with the temperature data measured using the methodology outlined in this work yielding agreement of the bulk particle temperature of the plume. The methods described here will be developed further to estimate the heat losses from the falling particle receiver at Sandia National Labs.
