La Ambivalencia Del Discurso Indigenista En La Nueva Narrativa Ecuatoriana

AbstractIndigenists such as the Ecuadorian novelist Jorge Icaza criticized the exploitation of the autochthonous population. However, this early indigenism of the nineteen thirties was characterized by an ambivalent discourse which explicitly condemned economic and political injustice, while implicitly revealing the influence of a negative attitude towards the Amerindians. In the neoindigenist novel of Gustavo Alfredo Jacome (1979), the depiction of an educated Amerindian gives rise to two different types of ambivalence. The indigenous protagonist is torn between a deep attachment to his culture, which he wants to preserve, and a condescending attitude towards his own people, who have not been able to educate themselves in Western institutions. At the same time, his knowledge of certain political theories leads to a problematical and ambiguous identification between the exploited Amerindians, Latin Americans in general whom he presents as victims of imperialism, and unsuccessful Communists of the entire w...

Reconfigurable flight control via multiple model adaptive control methods

An aircraft flight control system with reconfigurable capabilities is considered. A multiple model adaptive controller (MMAC) is shown to provide effective reconfigurability when subjected to single and double failures of sensors and/or actuators. A command generator tracker/proportional-plus-integral/Kalman filter (CGT/PI/KF) form of controller was chosen for each of the elemental controllers within the MMAC algorithm and each was designed via LQG synthesis to provide desirable vehicle behavior for a particular failure status of sensors and actuators. The MMAC performance is enhanced by an alternate computation of the MMAC hypothesis probabilities, use of maximum a posteriori probability (MAP) versus Bayesian form of the MAC (or a modified combination of both), and reduction of identification ambiguities through scalar residual monitoring for the case of sensor failures. >

Gas Chromatographic Analyses of Complex Hydrocarbon Mixtures Void of n-Paraffin Retention Index Markers Using Joint Mass Spectral and Retention Index Libraries

Complex hydrocarbon mixtures are analyzed by a gas chromatographic/mass spectrometric (GC/MS) method. Information from both a mass spectral library and a relative retention index library is used to identify the constituents of the mixtures. The ability of the mass spectral library to solve ambiguous retention index identifications and the ability of the retention index library to choose proper identifications from a ranking of mass spectral identifications is shown. A unique computer algorithm that allows the use of a Kovats retention index system on samples that do not contain a contiguous spectrum of the n-paraffins is demonstrated.

Resolution enhancement of backward propagated images by wavefield orthogonalization

Backward propagation is a convolution-type reconstruction algorithm designed for coherent holographic imaging which is commonly performed by frequency-domain filtering. When the size of the receiving apertures is small, image resolution is degraded due to the uncertainty caused by the incomplete measurement of the wavefield in addition to the limitation corresponding to the narrow spatial-frequency bandwidth. In this paper, the ambiguity of target identification is regarded as a result of nonorthogonal correlations of the wavefield signatures corresponding to distinct target locations. A resolution enhancement algorithm is presented by wavefield orthogonalization to uncorrelate the wavefield patterns to achieve resolution improvement on backward propagated images.

NTSC Color-Field Identification

There are four different color fields in an NTSC color signal, which are exactly defined by EIA RS170A. This paper argues that field identification derived from a comparison of horizontal sync, vertical sync, and subcarrier will always have an ambiguity of field identification. It further argues that if the video signal had an independent identification of color field, the system subcarrier phase could then be adjusted correctly in relation to horizontal sync at every source. An appropriate independent field identification flag would also provide the means to measure accurately the sync to subcarrier phase relationship using only a standard waveform monitor. Broadcast manufacturers of videotape equipment and digital equipment presently claim color-field recognition based on measurement of SCH (the sync to subcarrier relationship). It is suggested that an independent identification of the proper color field, irrespective of SCH, is the ultimate solution to the problem.

Concentric-Sphere Design for Spacing of Tag-Gas Isotopic Ratios

An analytical tag-design scheme is presented that can be used to compute the isotopic compositions for a system of tag nodes, used to identify failed fuel assemblies in reactors with gas-bonded nuclear fuels. The tag nodes are located uniformly across the surfaces of two concentric spheres. This design minimizes the possibility of ambiguous leaker identification in the event of double-assembly failures, while reducing the enrichment requirements for the noble gases used to create the tags. Reducing the enrichment requirements lowers the overall tag costs and makes the design particularly well suited for reactors requiring large numbers of distinct tags.

Adolescent Rebellion in the Kibbutz

The kind of changes that have appeared in adolescent rebellion phenomena in the kibbutz these past 10 years ate discussed from the sociocultural viewpoint. The frequency and expressions of the rebellion are conceived as connected closely with the interpersonal, family, social, and cultural context in which the adolescent exists. The increase of adolescent rebellion in the kibbutz seems to have occulted concurrently with the changes that have taken place in the surrounding environment making the system of values and norms in the life of the commune less clear and less valid. These changes have turned the adult society into a more ambiguous identification model than it was prior to the early 1960s.

Pseudo-maximum-likelihood speech pitch extraction

The pitch of a voiced speech segment may be estimated by minimizing the squared error in approximating the segment by the repeated weighted average of successive assumed pitch periods, after a maximum-likelihood solution originally due to Slepian. A modification is proposed which allows use of an arbitrary window function and corrects two faults of the likelihood function noted by Noll: a linear baseline rise and ambiguous identification of the proper peak. Computationally, the entire formulation is in the time domain. Results are presented for speech both before and after bandpass filtering to simulate telephone transmission. Comparison of these two cases implies that the algorithm is effective for speech in which the fundamental frequency itself is missing.

Symmetrization Effects in Spectator Momentum Distributions

The traditional identification of the slow nucleon as the in deuteron-breakup collisions is shown to be valid only when there is a significant difference in the speeds of the two nucleons. When both have similar speeds, symmetrization effects cannot be ignored. These effects will be particularly important (a) for low-momentum-transfer events and (b) for high-momentum spectator events. A new comparison technique free of these difficulties is suggested. By studying the transverse momentum spectrum for both final-state nucleons, one avoids ambiguous identification. In addition, the effect of the interference in such a distribution reveals the spatial symmetry of the final two-nucleon state. From this information it is possible to determine the relative contributions of spin-flip and -nonflip processes, and thereby to reconstruct the free-nucleon scattering accurately.

On a probabilistic interpretation of expansion coefficients in the non-relativistic quantum theory of resonant states

Abstract It is suggested that “complex probabilities” appearing in eigenfunction expansions involving resonant states can be interpreted in terms of two real probabilities. This is shown to be consistent with identification ambiguities due to the finite lifetime of such states.

Identification of charged particles by combination of the magnetic analysis and the ΔE, E method

A new method for detecting nuclear reaction products with Z ≲ 10 is described where the combination of the magnetic analysis and the ΔE, E method has been applied. The use of a telescope consisting of thin and thick detectors in the output focus of the magnetic analyzer eliminates the ambiguity of particle identification with magnetic analyzer due to various charge states and improves the mass resolution of the ΔE, E method.
