This paper presents a direct implementation of Government-Binding theory in a parser for German, which faithfully models the modular structure of the theory. The modular design yields a flexible environment, in which it is possible to define and test various versions of principles and parameters. The several modules of linguistic theory and the parser proper are interleaved in parallel fashion ...

The closed-form solutions of surface roughness parameters for a theoretical profile consisting of elliptical arcs are presented. Parabolic and simplified approximation methods are commonly used to estimate the surface roughness parameters for such machined surface profiles. The closed-form solution presented in this study reveals the range of errors of approximation methods for any elliptical a...

the main design objective of axial compressor is the efficiency increasing, pressure ratio and weight loss. these three parameters are used as an objective function and they are computed according to adopted design procedures. in this paper, a design method is presented that named quasi-three-dimensional. physical flow conditions are applied to design by some constraints to avoid irrational res...

Broadband microstrip filter operating within 1.5GHz bandwidth at UHF range for RF communication systems has been designed, simulated, and implemented using a practical network parameter method. The design has been performed using the network parameter method with ABCD parameters, which simplified the analysis significantly. The analytical, simulated and measured results have been compared and e...

Some design parameters of a hydrazine-oxygen fuel battery operating in a zero G field are described in a digital computer programming treatment. The power balance for a battery employing a gas-producing electrode and an electrolyte pump is treated; optimum power densities and flow rates are established. INTRODUCTION WITHIN the last decade fuel cell technology has advanced from the research stag...

In the design and manufacture of mechanical devices, there are parameters whose values are determined by the manufacturing process in response to errors introduced in the device’s manufacture or operating environment. Such parameters are termed tuning parameters, and are distinct from design parameters which the designer selects values for as a part of the design process. This paper introduces ...

Tactons (tactile icons) are structured vibrotactile messages which can be used for non-visual information presentation. Information can be encoded in a set of Tactons by manipulating parameters available in the tactile domain. One limitation is the number of available usable parameters and research is ongoing to find further effective ones. This paper reports an experiment investigating differe...

(V S A M) is followed b y a qualitative discussion of performance expectations. V S A M data-set design parameters are discussed with respect to performance tradeofs. Analytic techniques are developed for relating some of the VSAM performance sensitivities to data set design parameters. The Virtual Storage Access Method (VSAM)' has been developed for use with virtual storage operating systems. ...

Development and use of ontologies is increasing, but hampered by new challenges, such as determining which ontologies to reuse and which language to use. Ontology development methodologies provide scenarios, but they do not address the dependencies between the permutations at the different stages in the development process. To improve the efficiency and effectiveness of this endeavour, we group...

The paper presents the effect of conductive or lossy silicon (Si) substrates on the frequency-dependent distributed series impedance transmission line (TL) parameters, R(ω) and L(ω). The frequency variations of these parameters of the microstrip line for four different conductivities of Si substrate are observed and compared. Keysight Technologies (formerly Agilent’s Electronic Measurement Grou...
