Topic models based on latent Dirichlet allocation and related methods are used in a range of user-focused tasks including document navigation trend analysis, but evaluation the intrinsic quality topic model topics remains an open research area. In this work, we explore two automatic single whole models, provide recommendations best strategy for performing tasks, addition to providing open-source toolkit evaluation.

We present simulation results of flow-induced vibrations an infinitely long flexible cable at Reynolds numbers Re = 100 and 200, corresponding to laminar early transitional flow states, respectively. The question as what motions patterns prevail is investigated in detail. Both standing wave travelling responses are realized but general the preferred response. A response produces interwoven pattern vorticity, while a oblique vortex shedding. sheared inflow mixed wave/travelling chevron-like...

Apparent second-order rate coefficients have been determined for the reactions at 37 °C of diazodiphenylmethane with benzoic acid in 19 donor aprotic solvents. Values various initial concentrations acid, c, are analysed terms equation k(obs)=k0+k′c. Reactions acetic and deuteriated (PhCO2D MeCO2D) also studied. We conclude that k0 corresponds to reversible formation a complex between monomeric its subsequent breakdown products, while k′ reaction small amount highly reactive form an...

The objective of this study was to investigate the ability image color features predict subjective pork scores. Subjective and instrumental were assessed on bloomed, cross-sectional surface longissimus thoracis et lumborum chops. Images chop samples acquired using a computer vision system, 18 (mean standard deviation R, G, B, H, S, I, L*, a*, b*) extracted for inclusion in partial least squares (PLS) support vector machine (SVM) regression models. For scores 2, 3, 4, 5, accuracies 50.4,...

The objective of this study was to investigate the effects seasonal environment, transport conditions, and time in lairage on pork quality serum cortisol concentrations. Market hogs were slaughtered during winter (n = 535), spring 645), summer 644), fall 488). Within season, randomly assigned treatments a 2 × factorial arrangement, with deck locations (top vs. bottom) durations (3 h 6 h). Blood samples collected at exsanguination for analysis concentration. Loins 24 postmortem assessment....

We report kinetic studies on the reaction of a latex agglutination immunoassay used to quantify phenytoin in serum. In this assay, polystyrene particles with covalently attached analog react an antiphenytoin monoclonal antibody form light-scattering aggregates, rate being decreased by addition from sample. absence free (sample) phenytoin, did not exhibit maximum presence excess antibody, i.e., equivalence point. Furthermore, was inhibitable even when latter added after had begun. Most...

Apparent second-order rate coefficients have been determined for the reactions at 37 °C of diazodiphenylmethane with benzoic acid in 11 aprotic solvents which dimeric form predominates. Depending on solvent chosen, k(obs) shows one several forms dependence upon initial concentration acid, c. The mechanism previously developed reaction donor is applied and adapted to situation largely dimeric. Besides processes involving monomer dimer, kinetics suggest participation a reactive multimer,...

The purpose of this benchmarking study is to quantify pork quality variation in the retail self-serve meat case and provide information that can be used implement changes necessary meet National Pork Board SMART objective reducing having a subjective color score 1 or 2 by 10% year 2020. was benchmark from top 3 major retailers supermarkets each market area across United States according 2013 Progressive Grocer Marketing Guidebook (Stagnito Media, 2013). A total 133 supermarkets, representing...

This paper presents some of the challenges unique to a multi-mode transceiver supporting LTE and LTE-Advanced. Implications combining 2G, 3G 4G in single lineup are discussed. RF problems specific support discussed technical examples given. Specific solutions provided for duplex offset IIP2 receiver using calibration. Multiple transmit shown counter intermodulation issue resulting from inherent sideband problem caused by low RB count signaling.

The increasing interest in the measurement of serum C-reactive protein relation to risk stratification patients with chest pain has demonstrated need for more sensitive routine methods and an accurate definition reference range. We report determination a range samples from 491 blood donors using particle enhanced turbidimetric immunoassay that been modified offer better imprecision within median values were found be 2.40 2.20 mg/l males females, respectively 95th percentile 1.20-5.20...

Rate coefficients have been determined for the reactions at 30 °C of diazodiphenylmethane with cinnamic acid and meta-substituted acids (substituents: Me, Cl, or NO2) in 12 alcohols, ethyl acetate, acetone.The alcohols show a good linear free-energy relationship corresponding benzoic acid. The solvent effect can be interpreted terms dielectric constant influence hydrogen bonding. Multiple correlation three suitable parameters is quite successful. Comparisons are made phenylacetic system.The...

The objective of this study was to investigate the usefulness pork loin color image features in predicting two-tone grade according L* value. Nine (specifically, means for ratios R, G, B, L*, a*, b*, H, S and I) were extracted from 3 different spaces (RGB (Red, Green Blue), CIE LAB (L*: luminance; a*: green red; b*: blue yellow) HIS (Hue, saturation Intensity)). Color a laboratory-based high-quality camera imaging system. Objective (CIE a* b*) measured using Minolta Colorimeter, calibrated...

The objective of this project was to develop a computer vision system (CVS) for measurement pork loin under industry speed requirement. Color images samples were acquired using CVS. Subjective color and marbling scores determined according the National Pork Board standards by trained evaluator. Instrument crude fat percentage used as control measurements. Image features (18 features; 1 feature; 88 texture features) extracted from whole images. Artificial intelligence prediction model...
