Technical science and innovation

This article addresses the issue of errors occurring in high-speed production lines, particularly those caused by misalignment or incorrect positioning of manufactured objects. Although production lines have significantly enhanced industrial efficiency worldwide, they are not immune to mistakes, especially under rapid operation conditions. To mitigate these errors without human intervention, the proposed solution integrates photodetector sensor matrices with robotic manipulators. The system uses high-resolution photodetector arrays, such as the Hamamatsu S13774 CMOS Linear Image Sensor, to capture shadows of objects on the production line, converting these into numerical data. This data is then processed using Principal Component Analysis (PCA) and …

Real-Time Likelihood Map Generation To Localize Short-Duration Gamma-Ray Transients, Jeremy Buhler, Marion Sudvarg

Computer Science Faculty Research & Creative Works

High-energy transient astrophysical phenomena, such as supernovae and binary neutron star mergers, benefit from a multi-wavelength investigation in which a space- or balloon-based omnidirectional telescope detects and localizes early high-energy emissions (such as a gamma-ray burst), then alerts a narrow-field follow-up instrument to observe the source. The high-energy telescope must provide a map that assigns to each sky location a likelihood that the source appears there. To issue prompt alerts despite limits on communication bandwidth and latency, it is desirable to compute this map aboard the high-energy telescope, but doing so requires rapid response while computing under stringent size, weight, …

Effect Of Real Quest Outdoor Learning On High School Students Climate Literacy, Siti Aisah, Abdul Hakim, Puardmi Damayanti

Jurnal Pendidikan Sains

This study investigates the influence of the Real Quest Outdoor Learning (ReQOL) model, which encompasses knowledge, attitudes, and behavior, on the climate literacy of high school students. A quasi-experimental design was performed with a non-equivalent control group; thus, a sample consisting of an experimental class (n = 34) and a control class (n = 32) was used. A one-way ANOVA test was used to test the differences between pretest and post-test scores at a 0.05 significance level. The basic knowledge on climate in the experimental group increased significantly (sig < 0.001), while the change in attitudes and behaviors was insignificant (sig = 0.339 and sig = 0.447, respectively). The fact that attitude and behavior did not improve significantly during the experiment can be justified by the existing Adiwiyata programme in schools. These findings indicate that the ReQOL model is a good way to help students understand climate issues better. Adding discovery-based outdoor learning to science classes has the potential to make students more aware of environmental issues and lay the groundwork for the development of responsible behavior. This underscores the scientific contribution and educational importance of the development of climate literacy within the curriculum.

Locally Integral Involutive Po-Semigroups, José Gil-Férez, Peter Jipsen, Melissa Sugimoto

Mathematics, Physics, and Computer Science Faculty Articles and Research

We show that every locally integral involutive partially ordered semigroup (ipo-semigroup) A=(A,≤,⋅,∼,−), and in particular every locally integral involutive semiring, decomposes in a unique way into a family {Ap:p∈A+} of integral ipo-monoids, which we call its integral components. In the semiring case, the integral components are unital semirings. Moreover, we show that there is a family of monoid homomorphisms Φ={φpq:Ap→Aq:p≤q}, indexed over the positive cone (A+,≤), so that the structure of A can be recovered as a glueing ∫ΦAp of its integral components along Φ. Reciprocally, we give necessary and sufficient conditions so that the Płonka sum of any family …
