AN ECONOMIC EVALUATION OF LOW INVESTMENT SWINE PRODUCTION SYSTEMS
No full textThis publication summarizes an evaluation of smaller and lower investment swine production systems. The systems analyzed range from pasture operations with production during the warmer months to rather intense year-round use of remodeled buildings. In each case the system emphasizes use of facilities that can be constructed and remodeled by the farm operator. The report includes one section for each type of hog production: feeder pig production, farrow-to-finish operations and hog finishing.Livestock Production/Industries,
Design and FPGA implementation of a high-speed transposed Farrow structure for arbitrary resampling in digital receivers
No full textSample rate conversion is a fundamental operation performed in the digital front-end of software-defined radio and all-digital receivers. Within this context, polynomial-based filters, such as the Farrow structure and its variants, are a sound solution when arbitrary resampling is required. This paper presents a design methodology and the results of the implementation on a field-programmable gate array (FPGA) device for a high-speed transposed Farrow structure based on a novel parallel architecture. The implemented architecture supported an input sample rate of up to 2.184 GHz with moderate utilization of the FPGA resources. Furthermore, signal-to-noise ratio and spurious-free dynamic range values higher than 87 dB and 98 dB were reported over a wide range of sample rate conversion factors. Our results may suggest an improvement in the tradeoff between flexibility, complexity and throughput compared with previous work in the field

Dynamics of subclinical Salmonella infections in farrow-to-finish pig herds
No full textThe study objective was to investigate patterns of Salmonella shedding in finishing pigs. In each of 3 farrow-to-finish herds (A, B, and C), one cohort of fattening pigs (n=102, n=120, n=96, respectively) was selected.</p
Generating an Equation to Predict Post- Farrow Maternal Weight in Multiple Parity Sows
No full textost-farrow maternal weight is required when partitioning maternal and fetal weight gains throughout gestation. Equations were developed from the analysis of 150 females (Line 1050, PIC, Hendersonville, TN) to predict the weight of conceptus by difference of pre- and post-farrowing weight change in multi-parity sows. Females were individually weighed as they were moved into the farrowing house at d 110 to 112 of gestation and again at 12 to 24 h after farrowing. Data were divided into 4 groups: (1) parity 1 sows; (2) parity 2 sows; (3) parity 3 sows; and (4) parity 4+ sows. Each group tested 3 predictor variables: pre-farrow weight, total born, and difference in days between the pre- and post-farrow weights. Prediction equations were then developed using models with significant terms based on the Bayesian Information Criterion (BIC). The optimum equations to predict maternal body weight were similar for all parities except for the intercept (b) and can be described as:Post-farrow maternal body weight (lb) = b + (0.897 × pre-farrow BW, lb) - (1.118 × total born, n) + (6.87 × days pre to post-farrow, d)Where the intercept (b) for parities 1, 2, 3, and 4+ were -5.93, 5.15, 11.90, and 32.31, respectively.The prediction equations were then used to estimate post-farrow maternal BW using 332 mixed parity sows (PIC 1050). Pre-farrow weights were taken on d 113 of gestation and maternal BW was taken within 24 h of farrowing. On average, the predicted postfarrow maternal BW was overestimated by 3.3 lb of the actual. Management practices differed in how females were fed from the validation experiment, possibly contributing to the overestimating of post-farrow maternal BW. This indicates that further evaluation of the equation is needed to see if the difference is due to litter size, parity distribution, or feeding management practices
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A Typology for OER Business Models
No full textThis paper provides an update on activity in the innovation and business models strand of the ENCORE+ project. A range of business models that support or draw on open educational resources (OER) have been proposed. This paper reviews models that have been proposed (Tlili et al., 2020; Padilla Rodriguez et al., 2018; Belleflamme & Jacqmin, 2015; Ubachs & Konings, 2016; and Farrow, 2019) and suggests a synthesis into one typology of OER business models. The ENCORE+ OER Business Model Typology has been developed as part of a wider effort to understand and evaluate economically sustainable approaches to OER as well as to formulate OER value propositions for different stakeholders. In related work, a range of OER innovation case studies (N=48) are being prepared for publication. These will illustrate different instances of innovation with OER and show how OER actors understand their value proposition to different audiences
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
