Comparing herbicide application methods with See & Spray™ technology in soybean

New machine-vision technologies like the John Deere See & Spray™ could provide the opportunity to reduce herbicide use by detecting weeds and target-spraying herbicides simultaneously. Experiments were conducted for 2 yr in Keiser, AR, and …

A Review of Design of Experiments Courses Offered to Undergraduate Students at American Universities

Design of Experiments (DoE) is a relevant class to undergraduate students in the sciences, because it teaches them how to plan, conduct, and analyze experiments. In the literature on DoE, there are several contributions to its pedagogy, such as …

An integer programming approach for constructing maximin distance designs from good lattice point sets

Computer experiments can build computationally cheap statistical models to study complex computer models. These experiments are commonly conducted using maximin distance Latin hypercube designs (LHDs), generated using heuristic algorithms or …

Drying Techniques for Precooked Hybrid Rice to Ensure Quality of Instantized Rice

Background and objectives Due to the emergence of new hybrid rice cultivars, rice processors must refine their processing protocols to maintain the production of high-quality products. This is crucial for the instant rice processing industry. …

Mathematical programming tools for randomization purposes in small two-arm clinical trials: A case study with real data

Modern randomization methods in clinical trials are invariably adaptive, meaning that the assignment of the next subject to a treatment group uses the accumulated information in the trial. Some of the recent adaptive randomization methods use …

A Statistical Approach to Understanding How Inter-Kernel Moisture Content Variability Affects Rice Quality

Variability in moisture content between rice kernels due to the drying process within a harvest batch can result in irregularities in yields and the functional quality of the final product. Investigating strategies to achieve greater uniformity in …

Quality characteristic of instant rice produced using microwave-assisted hot air drying

It is of utmost importance for the instant rice processing sector to reassess its methodologies to enhance the overall quality of instantized rice products. This study aimed to analyze how the combination of microwave (MW) drying and convective …

Constructing two-level $Q_B$-optimal screening designs using mixed-integer programming and heuristic algorithms

Two-level screening designs are widely applied in manufacturing industry to identify influential factors of a system. These designs have each factor at two levels and are traditionally constructed using standard algorithms, which rely on a …

Systematic enumeration of two-level even-odd designs of strength 3

The first dedicated algorithm to enumerate even-odd designs of strength 3 is presented. Such designs cannot be constructed by folding over smaller designs, but they may permit simultaneous estimation of many more two-factor interactions than designs …

Systematic enumeration of definitive screening designs

Conference designs are $n \times k$ matrices, $k
