Short-Term Bus Passenger Flow Prediction Based On Convolutional Long-Short-Term Memory Network, Jing Chen, Zhaochong Zhang, Linkai Wang, Mai An, Wei Wang

Journal of System Simulation

Abstract: To address the problem that the traditional short-time passenger flow prediction method does not consider the temporal characteristics similarity between the inter-temporal passenger flows, a shorttime passenger flow prediction model k-CNN-LSTM is proposed by combining the improved k-means clustering algorithm with the CNN and the LSTM. The k-means is used to cluster the intertemporal timeseries data, the k-value is determined by using the gap-statistic, and a traffic flow matrix model is constructed. A CNN-LSTM network is used to process the short-time passenger flows with spatial and temporal characteristics. The model is tested and parameter tuned by the real dataset. …

Gauss Circle Problem Over Smooth Integers, Ankush Goswami

School of Mathematical & Statistical Sciences Faculty Publications

For a positive integer 𝑛, let 𝑟2(𝑛) be the number of representations of 𝑛 as sums of two squares (of integers), where the convention is that different signs and different orders of the summands yield distinct representations. A famous result of Gauss shows that 𝑅(𝑥) ∶= ∑ 𝑛≤𝑥 𝑟2(𝑛) ∼ 𝜋𝑥. Let 𝑃(𝑛) denote the largest prime factor of 𝑛 and let 𝑆(𝑥, 𝑦) ∶= {𝑛 ≤ 𝑥 ∶ 𝑃(𝑛) ≤ 𝑦}. In this paper, we study the asymptotic behavior of 𝑅(𝑥, 𝑦) ∶= ∑ 𝑛∈𝑆(𝑥,𝑦) 𝑟2(𝑛) for various ranges of 2 ≤ 𝑦 ≤ 𝑥. For 𝑦 in a …

The Combined Role Of Microbes And Forages In Animal Productivity, K. Panke-Buisse

IGC Proceedings (1977-2023)

Agricultural systems, particularly ruminant systems, are underpinned by diverse, functional microbial communities—in the soil, forage, silo, and rumen. We have relied on the jobs they perform on our behalf, but only recently have we been able to look “under the hood” at the membership and mechanisms within these microbiomes and begin to think about optimization. Ensiling is a common method of forage preservation globally and represents a highly intensive intersection between forage and microbiology, which has been shown to have beneficial effects on forage quality and dairy animal performance. However, observations of enhanced productivity, especially in the context of inoculated …

Ruminant Agriculture: A Tool For Climate Change Mitigation, B. L. Peterson Munks, M. Rellaford, J. Shanahan, S. Urbanowitz, F. Wang, S. Wang, Y. Zhao, E. Bender

IGC Proceedings (1977-2023)

The quest to address and mitigate climate change has been dubbed a “wicked problem” as it involves many interconnected processes requiring a multifaceted, comprehensive approach. Animal agriculture contributes roughly 15% to CO2 equivalent (CO2e) emissions; as a result, a concerted effort is being made to develop and promote more climate-friendly production practices. These practices include species diversification in grasslands, improving grazing rotation, adding nitrogen amendments, and the use of feed additives to reduce enteric fermentation. Successful inter-seeding of legumes and deep-rooted native grasses increases soil organic carbon (SOC) pools in many systems by increasing the biological carbon inputs to the …

Also since 2012, the Alliance has monitored and reported endophyte purity …

Economic Value Of Improving Feed Efficiency Of Beef Cows On Pasture, J. T. Biermacher, J. K. Rogers, D. Lalman, A. Holder, R. S. Walker

IGC Proceedings (1977-2023)

Dry matter intake of beef cows is based on a percentage of body weight, so as mature cow size increases, intake increases. Feed efficiency, or the amount of feed required to produce gain or maintain production, has a direct impact to the producer. That is, as mature cow weight increases, yearly maintenance costs increases due to higher feed costs. However, variation in feed efficiency exists within population. Some large cows consume the same or less dry matter as a smaller cow, but produce a larger calf. Conversly, some smaller cows consume the same or more as a large cow but …
