An Evaluation Approach For Interactions Between Abstract Workflows And Provenance Traces, Leonardo Salayandia, Ann Q. Gates, Paulo Pinheiro Jun 2012

An Evaluation Approach For Interactions Between Abstract Workflows And Provenance Traces, Leonardo Salayandia, Ann Q. Gates, Paulo Pinheiro

Departmental Technical Reports (CS)

In the context of science, abstract workflows bridge the gap between scientists and technologists towards using computer systems to carry out scientific processes. Provenance traces provide evidence required to validate scientific products and support their secondary use. Assuming abstract workflows and provenance traces are based on formal semantics, a knowledge-based system that consistently merges both technologies allows scientists to document their processes of data collection and transformation; it also allows for secondary users of data to assess scientific processes and resulting data products. This paper presents an evaluation approach for interactions between abstract workflows and provenance traces. The claim is …


Estimating Correlation Under Interval And Fuzzy Uncertainty: Case Of Hierarchical Estimation, Ali Jalal-Kamali May 2012

Estimating Correlation Under Interval And Fuzzy Uncertainty: Case Of Hierarchical Estimation, Ali Jalal-Kamali

Departmental Technical Reports (CS)

In many situations, we are interested in finding the correlation ρ between different quantities x and y based on the values xi and yi of these quantities measured in different situations i. The correlation is easy to compute when we know the exact sample values xi and yi. In practice, the sample values come from measurements or from expert estimates; in both cases, the values are not exact. Sometimes, we know the probabilities of different values of measurement errors, but in many cases, we only know the upper bounds Δxi and Δyi on …


Semi-Heuristic Target-Based Fuzzy Decision Procedures: Towards A New Interval Justification, Christian Servin, Van-Nam Huynh, Yoshiteru Nakamori May 2012

Semi-Heuristic Target-Based Fuzzy Decision Procedures: Towards A New Interval Justification, Christian Servin, Van-Nam Huynh, Yoshiteru Nakamori

Departmental Technical Reports (CS)

To more adequately describe human decision making, V.-N. Nuynh, Y. Nakamori, and others proposed a special semi-heuristic target-based fuzzy decision procedure. A usual justification for this procedure is based on the selection of the simplest possible membership functions and "and"- and "or"-operations; if we use more complex membership functions and "and"- and "or"-operations, we get different results. Interestingly, in practical applications, the procedure based on the simplest choices most adequately describes human preferences. It is therefore desirable to come up with a justification that explains this empirical fact. Such a justification is proposed in this paper


How To Define Average Class Size (And Deviations From The Average Class Size) In A Way Which Is Most Adequate For Teaching Effectiveness, Olga Kosheleva, Vladik Kreinovich May 2012

How To Define Average Class Size (And Deviations From The Average Class Size) In A Way Which Is Most Adequate For Teaching Effectiveness, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

When students select a university, one of the important parameters is the average class size. This average is usually estimated as an arithmetic average of all the class sizes. However, it has been recently shown that to more adequately describe students' perception of a class size, it makes more sense to average not over classes, but over all students -- which leads to a different characteristics of the average class size. In this paper, we analyze which characteristic is most adequate from the viewpoint of efficient learning. Somewhat surprisingly, it turns out that the arithmetic average is the most adequate …


Toxicity Of Tio₂ Nanoparticles In The Genomic Dna Of Cucurbita Pepo, Fabiola Moreno-Olivas^, Vincent Gant, Isaac Montes, Hiram Castillo-Michel, Kyle L. Johnson, Jose R. Peralta-Videa, Jorge L. Gardea-Torresdey* Apr 2012

Toxicity Of Tio₂ Nanoparticles In The Genomic Dna Of Cucurbita Pepo, Fabiola Moreno-Olivas^, Vincent Gant, Isaac Montes, Hiram Castillo-Michel, Kyle L. Johnson, Jose R. Peralta-Videa, Jorge L. Gardea-Torresdey*

COURI Symposium Abstracts, Spring 2012

The nanomaterial industry is growing very fast and nanoparticles (NPs) are used in variety of instruments and goods. NPs can reach the plants through different manners; though, little is known about their impact on food crops and the possible effects in the food chain are unknown. In this research, the possible genotoxic effects of TiO2 NPs on zucchinis (Cucurbita pepo) were studied. Seven-day old hydroponically grown zuchinnis plants were treated for 7 days with TiO₂ NPs suspended in the nutrient solution at concentrations varying from 0 to 50 mg/L. Random amplified polymorphic DNA assay was performed and showed the …

Impact Of Cerium Oxide Nanoparticles On Cilantro (Coriandrum Sativum), Ana C. Barrios^, Maria I. Morales, Cyren M. Rico, Jose R. Peralta, Jorge L. Gardea-Torresdey Apr 2012

Impact Of Cerium Oxide Nanoparticles On Cilantro (Coriandrum Sativum), Ana C. Barrios^, Maria I. Morales, Cyren M. Rico, Jose R. Peralta, Jorge L. Gardea-Torresdey

COURI Symposium Abstracts, Spring 2012

The impact of nanoparticles (NPs) on edible plants is currently a theme of great concern. Cerium oxide NPs (CeO2 NPs) are widely used in biomedical applications, fuel additives, and other consumer products. Studies have shown that these NPs are associated with liver damage. In addition, studies from our research group have also shown that CeO2 NPs are stored in plant tissues without modification. Thus, these NPs could be distributed in the food chain through edible plants, posing a threat for human health. Cilantro (Coriandrum sativum) is a very important culinary and medicinal plant worldwide. It is …

Generating Minimal Pair-Wise Covering Test Suites, Luis C. Gutierrez ^, Martine Ceberio *

COURI Symposium Abstracts, Spring 2012

Software is ubiquitous and needs to be reliable. Software testing therefore plays an important role in software development. Proper testing a software system informs about its quality and reliability so as to prevent unexpected behavior during system execution. One of the methods to prevent failures consists in testing a system under different input values, but when all possible input values are tested, an impractical number of test cases might result. In software testing, pair-wise testing is a combinatorial technique which uses combination of pair input values to generate test cases. Using pair-wise testing dramatically reduces the number of test cases, …
