Optimizing Course Offerings In A Science Department, Yu Kay Law

Academic Chairpersons Conference Proceedings

We will discuss how enrollment data and faculty/advisor input can be used to maximize schedule efficiency in course offerings and providing for student success. We will also discuss how best to monitor and rearrange course schedules in light of actual enrollment.

A Dynamic Run-Profile Energy-Aware Approach For Scheduling Computationally Intensive Bioinformatics Applications, Sachin Pawaskar, Hesham Ali

Computer Science Faculty Proceedings & Presentations

High Performance Computing (HPC) resources are housed in large datacenters, which consume exorbitant amounts of energy and are quickly demanding attention from businesses as they result in high operating costs. On the other hand HPC environments have been very useful to researchers in many emerging areas in life sciences such as Bioinformatics and Medical Informatics. In an earlier work, we introduced a dynamic model for energy aware scheduling (EAS) in a HPC environment; the model is domain agnostic and incorporates both the deadline parameter as well as energy parameters for computationally intensive applications. Our proposed EAS model incorporates 2-phases. In …

Dynamic Energy Aware Task Scheduling For Periodic Tasks Using Expected Execution Time Feedback, Sachin Pawaskar, Hesham Ali

Computer Science Faculty Proceedings & Presentations

Scheduling dependent tasks is one of the most challenging problems in parallel and distributed systems. It is known to be computationally intractable in its general form as well as several restricted cases. An interesting application of scheduling is in the area of energy awareness for mobile battery operated devices where minimizing the energy utilized is the most important scheduling policy consideration. A number of heuristics have been developed for this consideration. In this paper, we study the scheduling problem for a particular battery model. In the proposed work, we show how to enhance a well know approach of accounting for …

Irrigation Scheduling Of Drip-Irrigated Tomatoes Using Class A Pan Evaporation, Öner Çeti̇n, Osman Yildirim, Demet Uygan, Hasan Boyaci

Turkish Journal of Agriculture and Forestry

This study was carried out to investigate the irrigation schedule of drip-irrigated tomatoes (Lycopersicon esculentum cv. Dual Large, F 1) using Class A pan evaporation. Tomatoes plants were grown in a clay soil in the experimental fields of the Research Institute of Rural Services in Eskişehir between 1998 and 2000. Irrigation water was applied as a certain ratio of Class A pan evaporation (k_{pc} = 0.50, 0.75, 1.00, and 1.25) with different irrigation intervals (2, 4, and 6 days). Significant differences in fruit yields were obtained between the treatments, except for in 1998. Maximum marketable fruit yield was found at …

G97-1324 Beef Cattle Implant Update, Dicky D. Griffin, Terry L. Mader

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the mechanism of action and use strategies for growth promoting implants, including expected responses and cost analysis.

Introduction

Growth promoting implants have been used extensively in beef production for over 30 years. Significant changes in implants and implanting strategies have occurred. Prior to 1987, available implants were estrogenic agents which metabolically enhanced nutrient use to enhance growth. These products improved feed efficiency 5-10 percent and daily gains from 5-15 percent. In 1987, the androgenic (tissue building) agent, trenbolone acetate, was approved for use in growth promoting implants. This compound had an additive effect with existing estrogenic implants. …

Nf91-39 Precipitation And Sprinkler Irrigation Monitoring For Managing Irrigation Scheduling, Steve Meyer, Kenneth Hubbard

University of Nebraska-Lincoln Extension: Historical Materials

This NebFact discusses precipitation and sprinkler irrigation monitoring for managing irrigation scheduling.

Ec89-723 Irrigation Scheduling Using Soil Moisture Blocks In Silty Soils, William L. Kranz, Dean E. Eisenhauer

University of Nebraska-Lincoln Extension: Historical Materials

Irrigation takes some risk out of crop production by providing a reliable source of water that allows the producer to manage soil water. Monitoring soil water is fundamental to determining how much irrigation water should be applied, and when the soil is able to store the amount of water to be applied.

This publication describes how to use soil mositure blocks to schedule irrigations in fine textured soils.

G85-753 Irrigation Scheduling Using Crop Water Use Data, C. Dean Yonts, Norman L. Klocke

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes using the "checkbook" method to schedule irrigations based on crop water use data.

Irrigation scheduling determines when and how much water to apply to meet crop demand. Soil water status and current crop water use are key factors for scheduling irrigations. Field observations and crop growth stage are important, but scheduled irrigations result in better rainfall use while avoiding crop water stress or excessive irrigation.

Alfalfa Production As Related To Irrigation Scheduling: An Economic Perspective, Craig L. Israelsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study analyzed the economics of irrigation scheduling for alfalfa hay in the Cache Valley, Utah area. Yield, evapotranspiration (ET) and irrigation drainage loss, along with the costs and returns per acre attributable to irrigation scheduling, were simulated through the use of a computerized plant growth model. The model created yearly "irrigation schedules" for alfalfa hay based on actual climatic, soil and plant characteristic data from the Utah State University Greenville Experiment Station. The model calculated the irrigation schedules based on a soil-water balance equation which never allowed the available soil water to go below the crop stress point.

The …

G77-340 Scheduling Irrigation By Electrical Resistance Blocks, Paul E. Fischbach

University of Nebraska-Lincoln Extension: Historical Materials

Delay of irrigation for a few days during a critical part of the growing season can be expensive. A week's delay in supplying irrigation water to corn or grain sorghum can reduce potential yield more than 30 bushels per acre.

Several methods are available to help you schedule the right amount of water at the right time. One of these methods uses electrical resistance blocks discussed in this NebGuide.
