Abstract:
Abstract Fifty of Idaho's forest resource managers were queried about their outlook for sawtimber harvests and issues impacting future harvest levels. Identical questionnaires were sent to managers representing national forests, other public lands, forest industry, and nonindustrial private lands. Managers were first asked to estimate the impacts of 12 specific issues on past and future harvest levels, and then to provide estimates of future harvest levels for the lands directly under their control or jurisdiction. Managers expected sawtimber harvests in Idaho to decline through the year 2000. Idaho harvest levels between 1994 and 1996 were expected to fall 4.6% from average levels in the base period of 1991-1993, with further declines of 14.6% expected in 1997-2000. Across all ownerships, the most significant issues expected to affect harvest levels in Idaho are threatened, endangered, and sensitive species; cumulative impacts; and new forestry techniques. West.

Abstract:
As technological advances continue to help more people make connections with the entire world, students must understand how to use and interpret information shown in different maps of the world (Geography Education Standards Project 1994; Freese 1997). However, mental-mapping research suggests that students in the United States have major misconceptions about proportions, locations, and perspective when they work with maps (Dulli and Goodman 1994; Stoltman 1991).

Abstract:
This paper studies the negation construction in musgum language.We collect the musgum data on negation from native users and analyse them in terms of Kayne’s (1994) antisymmetry and Rizzi’s (1997) split CP approaches. We identify the free negation element (á:à) and several negation markers (kài, kirkài, kài tiŋ and kirkài tiŋ) that close independent and complex clauses. In complex structures with completive and relative clauses, the main clause cannot contain a negation marker. In complex structure with adverbial clause, negation marker can be present in main and adverbial clauses. We discover that Negation Phrase is the highest projection, higher than Force Phrase, rejecting the split‐CP projections order of Rizzi (1997). When the negation head is generated, Inflexion Phrase is subject to heavy pied‐piping. It occupies the specifier of Negation Phrase.

Abstract:
In the lizard, Ctenophorus ornatus, anatomical studies have revealed that optic axons regenerate to visual centers within 2 months of nerve crush but that, from the outset, the regenerated projections lack topographic order (Beazley et al., 1997; Dunlop et al., 1997b). Here we assess the functional topography of the regenerated retinotectal projections by electrophysiological recording of extracellular multiunit responses to visual stimulation and by observing the lizards' ability to capture live prey. At the completion of the electrophysiology, DiI was applied locally to the retina and the topography of the tectal projection later assessed. Electrophysiology revealed that, at 2–4.2 months, responses were weak and habituated readily; no retinotopic order was detected. Between 4.5–6 months, responses were more reliable and the majority of lizards displayed a crude retinotopic order, especially in the ventro-temporal to dorso-nasal retinal axis. Although responses were variable between 6–9 months, they tended to be more reliable again thereafter. However, from 6–18 months, the projection consistently lacked topography with many retinal regions projecting to each tectal locus. Lizards, including those with electrophysiological evidence of crude retinotopy, were consistently unable to capture live prey using the experimental eye. Labelling with DiI confirmed the absence of anatomical retinotopy throughout. Taken together, the electrophysiological and anatomical data indicate that retinotopically appropriate axon terminals (or parts thereof) are transiently active whilst inappropriately located ones are silent. Presumably in lizard map-making cues fade with time and/or the mechanisms are lacking to stabilize and refine the ephemeral map. Moreover, the transient retinotopy is insufficient for useful visual function.

Abstract. The main objective of the paper is to understand the contributions to the uncertainty in low flow projections resulting from hydrological model uncertainty and climate projection uncertainty. Model uncertainty is quantified by different parameterizations of a conceptual semi-distributed hydrologic model (TUWmodel) using 11 objective functions in three different decades (1976–1986, 1987–1997, 1998–2008), which allows disentangling the effect of modeling uncertainty and temporal stability of model parameters. Climate projection uncertainty is quantified by four future climate scenarios (ECHAM5-A1B, A2, B1 and HADCM3-A1B) using a delta change approach. The approach is tested for 262 basins in Austria. The results indicate that the seasonality of the low flow regime is an important factor affecting the performance of model calibration in the reference period and the uncertainty of Q95 low flow projections in the future period. In Austria, the calibration uncertainty in terms of Q95 is larger in basins with summer low flow regime than in basins with winter low flow regime. Using different calibration periods may result in a range of up to 60 % in simulated Q95 low flows. The low flow projections show an increase of low flows in the Alps, typically in the range of 10–30 % and a decrease in the south-eastern part of Austria mostly in the range −5 to −20 % for the period 2021–2050 relative the reference period 1976–2008. The change in seasonality varies between scenarios, but there is a tendency for earlier low flows in the Northern Alps and later low flows in Eastern Austria. In 85 % of the basins, the uncertainty in Q95 from model calibration is larger than the uncertainty from different climate scenarios. The total uncertainty of Q95 projections is the largest in basins with winter low flow regime and, in some basins, exceeds 60 %. In basins with summer low flows and the total uncertainty is mostly less than 20 %. While the calibration uncertainty dominates over climate projection uncertainty in terms of low flow magnitudes, the opposite is the case for low flow seasonality. The implications of the uncertainties identified in this paper for water resources management are discussed.

The ANOVA assessment of the relative contribution of the three main variance components (i.e. climate scenario, decade used for model calibration and calibration variant representing different objective function) to the low-flow projection uncertainty shows that in basins with summer low flows climate scenarios contribute more than 75 % to the total projection uncertainty. In basins with a winter low-flow regime, the median contribution of climate scenario, decade and objective function is 29, 13 and 13 %, respectively.

Abstract:
Category: Ankle Arthritis Introduction/Purpose: Ankle arthrodesis is commonly performed for patients with end stage ankle arthritis. However, with improvements in long-term outcomes following total ankle arthroplasty it is possible that rates of ankle arthrodesis will decrease as utilization of ankle arthroplasty increases. The purpose of this study is to assess the current and future trends of ankle arthrodesis utilization. Methods: National Inpatient Sample (NIS) data from 1997-2014 was used to identify trends in the utilization of ankle arthrodesis. United States Census Bureau data from 1997-2014 was used to identify historical population data and future population estimates. A linear regression model was created using Mathematica v11.3 to project future demand for ankle arthrodesis. The data was stratified to show past and future trends based on gender and age. Results: The overall utilization rate of ankle arthrodesis remained relatively constant from 5897 procedures in 1997 to 5330 procedures in 2014. The overall demand for ankle arthrodesis is expected to increase slightly by 15 percent with 6141 procedures projected in 2045. Stratified by age groups, the number of procedures is predicted to decrease by 75% in ages 18-44 and 6% in ages 45-64, and predicted to increase by 133% in ages 65-84 by 2045. Stratified by gender, ankle arthrodesis is predicted to increase by 47% in males and decrease by 14% in females in 2045. Conclusion: Based on our projection model, the rate of ankle arthrodesis is predicted to stay relatively stable overall but decrease in younger populations. A projected increase in total ankle arthroplasty will likely contribute to decreased utilization of ankle arthrodesis. However, ankle arthrodesis will still be a valuable tool in the surgeon’s armamentarium to treat ankle arthritis.

Neurophysiol. 78: 2221–2225, 1997. One proposed role of the superior colliculus (SC) in oculomotor control is to suppress or excite the activity of brain stem omnipause neurons (OPNs) to initiate or terminate saccades, respectively. Although connections from the SC to the OPNs have been demonstrated, the spatial distribution and discharge characteristics of the projecting neurons from the SC remain unknown. We mapped the spatial distribution of the deeper-layer neurons of the SC by stimulating the region of the OPNs to identify antidromic projections and found that the density of direct projections from the SC to the OPNs was greatest in the most rostral region and decreased gradually for more caudal sites. On the basis of saccade-related discharge characteristics, the antidromically driven neurons were predominantly fixation and buildup neurons. The spatially distributed SC projections to the OPNs and the discharge characteristics of the SC neurons suggest that the direct projections from SC to OPNs are excitatory. Finally, we propose how excitation and disfacilitation from SC activity can contribute to modulation of OPN response and control saccades.

Abstract:
The kernel of the semantic representation of a predicate in Role and Reference Grammar (RRG) is based on its characterization in terms of an Aktionsart typology based on Vendler’s (1957) classes plus some additional elements from Smith (1997) and Dowty (1979). This means that event structures are mainly considered a lexical phenomenon pertaining to predicates, and only occasionally higher predicational structures are considered in event construction. Even though this approach is adequate to a great extent, there are still some problems in the approach taken in RRG. The most significant drawback is that non-lexical aspects appear intermingled with predicate-only features, which leads to misinterpretations and misclassifications of predicates. Consequently, it sees more sensible to bring a functional model of grammar like RRG to a compromise position and, thus, consider in what ways different units identified as belonging to the different layers in RRG’s syntactic projections ‘conspire’ in the final aspectual characterization of events. In this line, this paper will propose a classification of aspectual features in terms of the levels found in the functional projection of the clause as devised in RRG, namely the Predicate Level (the domain of Aktionsart typology), the Nucleus (where morphological aspect has scope) and the Core (the locus for what will be described as ‘aspectuality’ features).

The adult male and pupa of a new species of the genus Neoatriplectides Holzenthal, 1997, are described and figured based on specimens collected in the Mantiqueira Mountain Range, southeastern Brazil. A male of Neoatriplectides desiderata, sp. nov., was associated with the unidentified larva described by Holzenthal, 1997. The new species is differentiated from N. froehlichi Holzenthal, 1997, mainly by the division of abdominal segment X into 2 triangular projections, absent in N. froehlichi. The pupal description is the first for this genus.

Abstract:
Enrollment projections are used by school administrators to predict the number of students expected to attend a school district within a defined period of time. This dissertation examines methods used for making enrollment projections and seeks to improve these methods through the application of geographic principles. The presented thesis challenges the existing aspatial framework used to calculate grade progression rates, arguing that a spatial framework improves projection accuracy. Grade progression rates are the critical element in enrollment projections and this dissertation's major contribution is the analysis of four different grade progression rate calculations at the school district level. This dissertation also argues that grade progression rates represent spatial relationships of migration that exist between adjacent school districts and uses these spatial relationships to create a new spatial Bayesian approach. This dissertation demonstrates that geographic methods can be successfully integrated to improve enrollment project accuracy through the reduction of the small number problem. In addition, this research identifies the importance of smoothing effects of the modified cohort progression method when compared to Bayesian approaches.

Abstract:
Working as an architect means being able to see the main issues of a design, examining with objectivity the possible solutions and finally grasp the technical means necessary to accomplish the project. I think that it is important for an architect to be involved in the entire course of a project, since the process of "building" is a simultaneous rather than a sequential one. My architectural education and my work experience as an intern in architecture firms in Germany prepared me well for practice. It covered many technical issues and equipped me with the fundamentals of architectural assembly. Graduate education in the United States provided me with the academic environment to investigate my interests more deeply and to discover my personal strengths. It gave me the opportunity to formulate a mature and coherent position in my thinking and making. I still cannot explain everything intellectually, since many ideas are intuitively derived or spring from my sub-consciousness. But my theoretical and practical background combined with sincere feedback from my classmates and committee members provided the necessary climate to develop and elaborate architectural ideas. I see life as a continuous course of learning, where personal growth not only strengthens my confidence, but also contributes to the discipline of architecture and to society at large. An architect has a special responsibility towards society as he/she translates the spirit of time into the built cultural environment.

Full text
Abstract:
This thesis examines questions of the continued significance of national cinemas and identities, focussing on the case of Scottish cinema. As a small, devolved nation with relative autonomy from the United Kingdom, Scotland presents an interesting case for how films are labelled with a national identity, as Scottish films can also often be understood in a British, European, and even global context. Rather than attempting to construct a working model of Scottish cinema based on representation or production context, I ask how films have been constructed as Scottish. I approach the concepts of Scotland and Scottish film as sets of meanings that are subject to change over time and in different contexts. This facilitates a perspective which asks in what ways Scotland and Scottishness is constructed in film. I examine how multiple identities are balanced in the filmic construction of Scotland first by considering how Scottish films—both those made in and which are about Scotland—from the early 1980s to the present construct Scottish identities. I will consider the way these films explored ‘traditional’ Scottish identities in the 1980s, Scottish masculinity in the 1990s, and Scottish identities based on ethnicity and gender in the 2000s and 2010s. Second, I look at how these films are received as Scottish by examining reviews and other press materials to determine how the Scottishness of the films considered is discursively constructed for potential audiences.

Full text
Abstract:
This thesis uses Higson’s (2000) approach to national cinemas (that they look inward and outward to define their boundaries) to investigate how Spanish stardom interacted with the national between 1992 and 2007. The thesis examines four specific stars as case studies, and finds that there is a correlation between the cinema produced and the stars created, and that stars are as reflective of their national cinema as they are of current cultural perceptions and conceptions of nationness. The thesis therefore provides a detailed investigation of contemporary Spanish stardom within the framework of the interrelations between Spanish cinema and the four chosen stars in their reflections and projections of the national. Perriam (2003), Babington (2001), and Vincendeau (2000) show that the relationship between stars and the national informs the shape and content of their stardom, but this thesis argues that stars negotiate industrial imperatives as well as the cultural contexts of their nation; the national, cultural, and industrial converge in the star image. In investigating the stardom of Javier Bardem, Penélope Cruz, Eduardo Noriega, and Paz Vega –who emerged at different points during the period– this thesis finds that the manner in which Spanish stars interacted with the national onscreen gradually changed owing to factors specific to the Spanish film industry in this era. Textual analysis of star images and performances and cultural contextualisation are employed to argue that as the influences within Spanish cinema have become more culturally diverse, and the boundaries of ‘Spanish cinema’ have expanded, newer Spanish stars are less obviously ingrained with Spanishness and their reflections and projections of the national become less overt. Although this is suggestive of a gradual dilution of national characteristics within Spanish cinema and stardom, this thesis finds that the newer stars nonetheless still reveal something of their changing Spanish culture and society.

Abstract:
Abstract The effort/motion approach has been developed for use in designing, simulating and controlling multibody systems. Some aspects of each of these topics are discussed here. In the effort/motion formulation two sets of equations based on the orthogonal projections of a dimensional gauge invariant form of Newton’s Second Law occur. The projections are onto the normal and tangent directions of a dimensional gauge invariant constraint surface. The paper shows how these equations are obtained for a particular linkage with redundant effort and motion actuation. Two alternative Runga-Kutta based approaches for numerical simulation of the effort/motion equations are developed and applied in simulating the motion and determining the effort generated in the example linkage under various conditions. Oscillation about equilibrium positions, solutions with constant motion and with constant effort are given as examples of the approach.

Full text
Abstract:
Abstract As the extensive use of solid models becomes widespread, it is important to have a mechanism by which existing engineering drawings can be converted into solid models. Therefore, a geometric assistant which can aid in the construction of solid models is beneficial. In this paper, we present key operations for a system called the Assistant for the Rapid Construction of Solids (ARCS), that provides this assistance given a set of two orthographic views. ARCS is based on the Visual Reasoning Tutor (VRT), a system we developed that provides users with the geometric framework to build polyhedral solids from their orthographic views. However, the geometric domain of ARCS encompasses non-polyhedral solids with cylindrical and spherical surfaces, such as those found in typical mechanical parts. We have devised the Cylindrical and Spherical Warping operations to create cylindrical and spherical surfaces, which use interactive computer graphics that guide a human user to build non-polyhedral faces of a solid. These operations are then illustrated with an example using ARCS to create the solid model of a typical mechanical part from its orthographic projections.

Abstract:
Abstract This paper presents a multi-index variable time step method for the integration of the equations of motion of constrained multibody systems in descriptor form. The basis of the method is the augmented Lagrangian formulation with projections in index-3 and index-1. The method takes advantage of the better performance of the index-3 formulation for large time steps and of the stability of the index-1 for low time steps, and automatically switches from one method to the other depending on the required accuracy and values of the time step. The variable time stepping is accomplished through the use of an integral of motion, which in the case of conservative systems becomes the total energy. The error introduced by the numerical integrator in the integral of motion during consecutive time steps provides a good measure of the local integration error, and permits a simple and reliable strategy for varying the time step. Overall, the method is efficient and powerful; it is suitable for stiff and non-stiff systems, robust for all time step sizes, and it works for singular configurations, redundant constraints and topology changes. Also, the constraints in positions, velocities and accelerations are satisfied during the simulation process. The method is robust in the sense that becomes more accurate as the time step size decreases.

Full text
Abstract:
Abstract The well-known pictorial drafting technique of isometric drawing is here generalized in two ways, called “isoclinal” and “axial”, or collectively, “symmetric”. Although the isoclinal projection preserves the useful property of foreshortening adjacent edges equally, and the axial projection foreshortens adjacent edges equally, the directions for these projections usually differ from that for isometric projection. Formulas are derived for the isoclinal and axial directions and their foreshortening factors and rotation matrices. Although intended for three-dimensional computer-aided design, the symmetric projections can also be performed on a drawing board with a protractor. Graphic examples involving design of non-rectangular connectors for three skew structural members and adjacent plates in space are presented.

Full text
Abstract:
Recent projections foster the belief that small high temperature heat exchanged gas turbines incorporating ceramic rotors, and ceramic exhaust beat exchangers, may eventually have thermodynamic efficiencies competitive with Diesel cycle engines. Small high speed Brayton cycle gas turbine turbogenerators on the near term verge of production will indeed have improved thermal efficiencies, but ceramic material technology has not yet matured to the engine production stage. Although thermal efficiency is a dominant driver, manufacturing costs and long term engine durability are still a major concern to the engine manufacturer. As a consequence the thermodynamic performances of small gas turbines are still, in this last decade of the 20th century, primarily constrained by the temperature limits of the metallic stator/rotor and metallic heat exchanger. This paper reviews optimum thermo-economic design considerations for a small 50 KW output turbogenerator, covering the effect of cycle performance parameters on, engine configuration, rotational speeds engine weight, manufacturing and direct operating costs. The effect of design pressure ratio on part load thermal efficiency is also addressed for applications with extended operating time at low output powers.

Full text
Abstract:
Abstract This paper describes an algorithm to generate 3-D solid models of objects from their orthographic projections. This approach is entirely different from the earlier bottom-up approaches. Instead of generating the 3-D vertices, edges and faces sequentially, this approach considers an object to be the boolean combination of a number of elementary objects, which are 2.5D solids. The elementary objects are formed by decomposing a given view into loops and sweeping each loop perpendicular to the direction of projection. This algorithm can handle objects whose projections have curved edge(s) in one view of the orthographic projection. It is believed that proper extension of this algorithm can handle sectional views and multiple views, which has not been addressed in the bottom-up approach.

Abstract:
Abstract Feature modelling is now being used quite extensively in the context of manufacturing of parts. It is shown that the use of features in product models, instead of geometric information only, can be very useful in assembly as well. This is done by introducing two types of assembly features, handling and connection features, and by outlining their usability in several assembly planning modules. It is also shown that in assembly feature modelling the concept of internal freedom of motion can be profitably used. Internal freedom of motion can be represented with visibility maps, which can be transformed using the central projection method. An extension of the central projection method, projecting a visibility map onto a cube, is described.

Abstract:
This review focuses on modern energy attributes and to identify alternative energy source and technology that satisfy energy trilemma requirements. The results and findings of the study show that photovoltaic (PV) solar cells technologies have the potentials of satisfying the global energy quest if deployed more. This study x-rays the different PV cells technologies in terms of generation chronology, power conversion efficiencies (PCE), (EPBT), present status and outlook. This study harmonises many photovoltaic performance indexes from review as follow: PV module power conversion efficiencies (PCE) of solar cells: lab -mono-Si (26.7%), multi-Si (22.3%), CIGS (21.7%), for and CdTe (21.0%); commercial - mono-Si (17%), CdTe (16.0%); energy payback time (EPBT) in Europe, 1–1.5 years and 1.5–3.5 years for thin film and crystalline silicon PV systems, respectively, 3 months and 8 months for perovskite (PSC) and CdTe solar cells respectively. The price of PV has drastically declined from $76/W in 1997 to $0.3/W in 2015. By 2050 and 2100, PV solar technology is expected to provide 20% and over 60% of the world’s energy supply, respectively. This will account for 50% CO2 emissions reduction globally. The projections depend on further improvement on the performance indexes and lifetime, series resistance, and optical properties. CdTe technology performs better than other technologies at elevated temperature, hence, recommended for tropical regions.
