Archaeological Testing In An Area South of Olmos Dam, San Antonio, Texas

During November of 1977, five days of archaeological testing were carried out by personnel from the Center for Archaeological Research, The University of Texas at San Antonio, directly south of Olmos Dam, San Antonio, Texas (see Fig. 1). The testing was done under the supervision of Dr. Thomas R. Hester, Director, and Jack D. Eaton, Assistant Director, and was performed under the terms of a contract between CAR and the San Antonio River Authority. The project conforms to the provisions outlined in the E.D.A. Special Terms and Conditions (III 3a), Grant Number 08-19-01911. Antiquities Permit #161 was obtained from the Texas Historical Commission before field work commenced

Archaeological Testing in the Devine Road Area North of Olmos Dam, San Antonio, Texas

During late January and early February 1978, archaeological testing was carried out in an area north of Olmos Dam, San Antonio, Texas (see Fig. 1) by personnel from the Center for Archaeological Research (CAR), The University of Texas at San Antonio. This work was performed under contract between CAR and the San Antonio River Authority. The area tested consisted of 16 acres bounded by Olmos Dam to the south, Devine Road to the west and Olmos Creek to the north and east. The objective of the testing was to determine whether any historic or prehistoric resources were present and, if so, to evaluate their significance prior to the use of the location as a borrow pit during the planned renovation of Olmos Dam. During the construction of Olmos Dam in the 1920s, a prehistoric site, 41 BX 1, was uncovered and mostly destroyed. Current testing in this area was designed to determine if any part of the site was left intact and to make recommendations for mitigation or protection. The archaeological testing was performed under the supervision of Dr. Tomas R. Hester, Director and Mr. Jack D. Eaton, Assistant Director, of CAR. The field work was directed by Cristi Assad with the assistance of Augustine Frkuska, Rebekah Halpern and Robert F. Scott. All notes, maps and materials collected are on file at the Center for Archaeological Research

Design and Optimization of a Low DC Offset in Implanted System for ENG Recording Based on Velocity Selectivity Method

The major target of this paper is the design of advance signal processing system based on minimized length of bits required for digital-to-analogy converter (DAC) for velocity selectivity recording (VSR) approach. The main application of this device is peripheral nerves recording (electroneurogram-ENG) by exploring a spectral analysis for the propagation of neural activities in the velocity domain recording using VSR in implantable application. This research adapted a flexible, compact, andnbspenergynbspefficient dc offset removal circuit. An optimization design has been used based on best possible process involving linearity and area is thus suggested. The system process acquired using this approach were characterized as having a 10-bit signal processing for DAC resolution, with 1.4 mA rms output current, with minimum size around 0.02 mm2nbspof chip area, using FPGA board as prototype design. This paper also explores the design temperature vibration in online recording minimization the output DC offset decrease the heat emission which is significantly for long term implementation applications. This study proposed an analysis circuit configuration demonstrate that this approach could achieve a small DC offset error, with small size required

A few-shot graph Laplacian-based approach for improving the accuracy of low-fidelity data

Low-fidelity data is typically inexpensive to generate but inaccurate. On the other hand, high-fidelity data is accurate but expensive to obtain. Multi-fidelity methods use a small set of high-fidelity data to enhance the accuracy of a large set of low-fidelity data. In the approach described in this paper, this is accomplished by constructing a graph Laplacian using the low-fidelity data and computing its low-lying spectrum. This spectrum is then used to cluster the data and identify points that are closest to the centroids of the clusters. High-fidelity data is then acquired for these key points. Thereafter, a transformation that maps every low-fidelity data point to its bi-fidelity counterpart is determined by minimizing the discrepancy between the bi- and high-fidelity data at the key points, and to preserve the underlying structure of the low-fidelity data distribution. The latter objective is achieved by relying, once again, on the spectral properties of the graph Laplacian. This method is applied to a problem in solid mechanics and another in aerodynamics. In both cases, this methods uses a small fraction of high-fidelity data to significantly improve the accuracy of a large set of low-fidelity data

Recovery of cellular traction in three-dimensional nonlinear hyperelastic matrices

The traction exerted by a cell on the extra-cellular matrix (ECM) is critical to understanding and manipulating important biological processes such as stem cell differentiation, cancer cell metastasis, and embryonic morphogenesis. This traction is typically quantified through traction force microscopy (TFM). In TFM, the displacement of select markers inside the ECM is tracked, and is used in conjunction with an elasticity problem to reconstruct the traction field. Most applications of this technique thus far have assumed that the matrix behaves as a linear elastic solid that undergoes small deformation and infinitesimal strains. In this manuscript, we develop and implement a robust and efficient TFM methodology that overcomes these limitations by accounting for geometric and material nonlinearities in the ECM. We pose the TFM problem as an inverse problem and develop efficient adjoint-based minimization techniques to solve it. We test the effect of measurement noise on the proposed method, and examine the error incurred by not including nonlinear effects when solving the TFM problem. We present these results for in-silico traction fields that are applied to realistic geometric models of microglial and neuronal cells

Using Animated Infographics to Educate Starters on the Saudi Labor and Workmen Law

The present study aims to educate starters to work on the Saudi Labor and Workmen Law and making a proposal to educate them by employing animated infographics. It also defines the quality of the animated infographics from the perspective of the target group to educate starters to work on the Saudi Labor and Workmen Law. Therefore, the authors selected and designed animated infographics using Vyond software of the most important articles in the implementing regulation of the Saudi Labor and Workmen Law from signing to terminating a work contract to educate the fresh graduates and starters in Saudi Arabia. They also developed and applied a questionnaire to (50) fresh graduates and starters to measure the feasibility of employing animated infographics in raising their awareness of the Saudi Labor and Workmen Law. The results showed that the animated infographic proved effective in raising the awareness of the participants of the Saudi Labor and Workmen Law. The authors recommended the need to employ animated infographics in educating starters on the developments of the Saudi Labor and Workmen Law to enhance learning. They also recommended that the field training supervisors should use the designed animated infographic in developing the programs of graduate qualification for the labor market
