Bibliographic record
Abstract
RESUME La societe technique PolyOrbite de l’Ecole Polytechnique de Montreal entreprend de concevoir un nanosatellite ayant une taille de 30cm*10cm*10cm et un poids de 4 kg, appele ORU-S. Le lancement du satellite est prevu pour 2020 avec deux charges utiles independantes dont un incubateur miniaturise. Le but de l’incubateur est de mener une experience botanique dans l’espace afin d’etudier l’effet de la microgravite sur la croissance de la plante comestible Medicago truncatula. Depuis les annees 90, les plateformes de nanosatellites ont pris de l’essor, mais les travaux de recherche effectues dans le domaine des serres miniaturisees et de la botanique spatiale restent limites. A ce jour, aucun projet n’a reussi a faire croitre une plante comestible dans un nanosatellite. Ce memoire de maitrise presente le design conceptuel d’un incubateur miniaturise. Cet incubateur est un laboratoire in situ qui permet la germination d’une plante en suivant et controlant les parametres environnementaux pour fins de recherche scientifique. Apres la validation du cahier des charges, un design conceptuel est realise avec plusieurs concepts potentiels en appliquant la Conception Axiomatique. En outre, a cause de la multidisciplinarite du probleme de design, la determination du « meilleur » est effectuee en appliquant le Profil Multicritere Mecatronique (MMP) developpe par l’equipe du Prof. Achiche. La solution presentee, dans ce memoire, est un incubateur pressurise compose de quatre sous-systemes : systeme de culture, systeme de controle de temperature, systeme d’approvisionnement et systeme d’inspection. Les trois premiers systemes fournissent les conditions necessaires a culture, soient une source d’illumination, une temperature convenable et une quantite satisfaisante de solutions nutritives qui permettent la croissance de la plante. Alors que le systeme d’inspection, il assure l’obtention et l’enregistrement des donnees pour les tâches de controle pour supporter la recherche scientifique dans ce domaine. Les travaux futurs se concentreront sur l’approfondissement de la conception optimale en utilisant des fonctions specifiques pour resoudre des problemes comme la gestion d’espace. Mener une experience terrestre dans un prototype basant sur la conception sera aussi interessant afin de verifier la fonctionnalite du design.----------ABSTRACT The technical association PolyOrbite of Ecole Polytechnique de Montreal is developing a nanosatellite with a size of 30cm*10cm*10cm and a weight of 4 kg, called ORU-S. This satellite will launch in 2020 with two independent payloads including a miniaturized incubator which is considered to conduct a botanical experiment in space to study the effect of microgravity on the growth of the plant Medicago truncatula. Despite the growth in popularity of the CubeSat platform from 1990, research in the areas of miniaturized greenhouses and astrobotany has been very limited. It seems that no project has made to grow a plant in space in a nanosatellite. So, this thesis presents a conceptual design of the miniaturized incubator being an in-situ laboratory that allows germination of the plant by monitoring and controlling the environmental parameters for scientific research. After the validation of the requirements specification, we implemented a preliminary design with several potential concepts by applying Axiomatic Design. In addition, because of the multidisciplinarity of the design problem, the determination of the best concept is carried out by applying the Multi-criteria Mechatronics Profile developed in the laboratory of Prof. Achiche. The solution presented in this thesis is a pressurized incubator consisting of four subsystems: cultivation, temperature control, supply, and inspection systems. The first three systems provide the necessary conditions for the plant: a source of illumination, a suitable temperature, and a satisfactory amount of nutrient solutions that allow the growth of the plant. As for the inspection system, it ensures data collection for control and scientific research. Future work will deepen the design using specific functions to solve problems such as space and layout management. Conducting a ground experience in a prototype based on the design will also be interesting to verify the functionality of the developed design.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
