title: PDF2LaTeX: A Deep Learning System to Convert Mathematical Documents from PDF to LaTeX
abstract: The mathematical contents of scientific publications in PDF format cannot be easily analyzed by regular PDF parsers and OCR tools. In this paper, we propose a novel OCR system called PDF2LaTeX, which extracts math expressions and text in both postscript and image based PDF files and translates them into LaTeX markup. As a preprocessing step, PDF2LaTeX first renders a PDF file into its image format, and then uses projection profile cutting (PPC) to analyze the page layout. The analysis of math expressions and text is based on a series of deep learning algorithms. First, it uses a convolutional neural network (CNN) as a binary classifier to detect math image blocks based on visual features. Next, it uses a conditional random field (CRF) to detect math text boundaries by incorporating semantics and context information. In the end, the system uses two different models based on a CNN LSTM neural network architecture to translate image blocks of math expressions and plaintext into the LaTeX representations. For testing, we created a new dataset composed of 102 PDF pages collected from publications on arXiv.org and compared the performance between PDF2LaTeX and the state of the art commercial software InftyReader. The experiment results showed that the proposed system achieved a better recognition accuracy (81.1% measured by the string edit distance between the predicted LaTeX and the ground truth.

title: Water Testing Natural Rubber Latex Condoms: A Comparison of Surveillance Test Methods
abstract: Manufacturers, consumers, and regulators use various water test methods to test the integrity of the barrier offered by natural rubber latex condoms. The purpose of this study is to analyze three alternative water test methods and determine which is the best method for detecting holes in condoms. Three types of holes (laser, acupuncture, and 28 gage insulin needles) approximating defects that occur in condoms, were placed in condoms and then into equal size test sets for testing by six laboratories for the purpose of evaluating the three alternative methods: the ASTM method, the ISO/FDA method, and the CSI/FHI method. Each method shares a hang portion for 1 min, and then uses a different form of manipulation; either elevate (ASTM) roll (ISO/FDA) or squeeze (CSI/FHI) The interlaboratory study data indicate the CSI/FHI is the most sensitive method for locating holes in condoms, becoming more sensitive as the defect approaches the closed end.

title: Determination of burst initiation location and tear propagation velocity during air burst testing of latex condoms
abstract: The stress testing of latex condoms by an air burst procedure has been slow in gaining industry acceptance because questions have been raised regarding the influence of the test apparatus on the likelihood of breakage occurring where the condom is attached to the inflation device. It was desired to locate the areas at which the condoms tend to burst and thus corroborate or disprove these claims. Several factors associated with the bursting condom demanded the use of special instrumentation to detect arid study the burst initiation process. Microsecond duration electronic flashes were used for the initial stages of the investigation. Although the absolute point of initiation of a given burst could not be photographed, these high speed studies tend to indicate that the most likely place for high quality condoms to break is not where they are attached to the inflation device but at an intermediate area between the base and the tip of the condom. In addition, tear propagation characteristics and velocities were determined with a delayed flash technique, a double slit strip method and a rotating drum framing camera.

title: HEtest: A Homomorphic Encryption Testing Framework
abstract: In this work, we present a generic open source software framework that can evaluate the correctness and performance of homomorphic encryption software. Our framework, called HEtest, automates the entire process of a test: generation of data for testing (such as circuits and inputs) execution of a test, comparison of performance to an insecure baseline, statistical analysis of the test results, and production of a LaTeX report. To illustrate the capability of our framework, we present a case study of our analysis of the open source HElib homomorphic encryption software. We stress though that HEtest is written in a modular fashion, so it can easily be adapted to test any homomorphic encryption software.

title: Technical Note: A new phantom design for routine testing of Doppler ultrasound.
abstract: The objective of this project is to demonstrate the principle and operation for a simple, inexpensive, and highly portable Doppler ultrasound quality assurance (QA) phantom intended for routine QA testing. A prototype phantom has been designed, fabricated, and evaluated. The phantom described here is powered by gravity alone, requires no external equipment for operation, and produces a stable fluid velocity useful for quality assurance. Many commercially available Doppler ultrasound testing systems can suffer from issues such as a lengthy setup, prohibitive cost, nonportable size, or difficulty in use. This new phantom design aims to address some of these problems and create a phantom appropriate for assessing Doppler ultrasound stability.  The phantom was fabricated using a 3D printer. The basic design of the phantom is to provide gravity powered flow of a Doppler fluid between two reservoirs. The printed components were connected with latex tubing and then seated in a tissue mimicking gel. Spectral Doppler waveforms were sampled to evaluate variations in the data, and the phantom was evaluated using high frame rate video to find an alternate measure of mean fluid velocity flowing in the phantom.  The current system design maintains stable flow from one reservoir to the other for approximately 7 s. Color Doppler imaging of the phantom was found to be qualitatively consistent with laminar flow. Using pulsed spectral Doppler, the average fluid velocity from a sample volume approximately centered in the synthetic vessel was measured to be 56 cm/s with a standard deviation of 3.2 cm/s across 118 measurements. An independent measure of the average fluid velocity was measured to be 51.9 cm/s with a standard deviation of 0.7 cm/s over 4 measurements.  The developed phantom provides stable fluid flow useful for frequent clinical Doppler ultrasound testing and attempts to address several obstacles facing Doppler phantom testing. Such an ultrasound phantom can make routine testing more approachable for institutions that wish to initiate a Doppler QA program or complement a previously existing QA program.

title: Determining optimal quality distribution of latex weight using adaptive neuro fuzzy modeling and control systems
abstract: This paper introduces a systematic approach for the design of an adaptive neuro fuzzy inference system (ANFIS) for latex weight control of level loop carpets. In high production volume of some industries, manual control could lead to undesirable variations in product quality. Therefore, process parameters require continuous checking and testing against quality standards. One way to overcome this problem is to use statistical process control by which a complete elimination of variability may not be possible. Fuzzy logic (FL) control is one of the most significant applications of fuzzy logic and fuzzy set theory. Fuzzy if then rules (controllers) were developed in a systematic way that formed the backbone of the neuro fuzzy control system. The developed ANFIS was able to produce crisp numerical outcomes to predict latex weights. The neuro fuzzy system behaved like human operators. ANFIS outcomes were encouraging because they provide a more efficient and uniform distribution of latex weight and seemed to be better than the other statistical process control tools. FL controllers provide a feasible alternative to capture approximate, qualitative aspects of human reasoning and decision making processes.
