Teaching equipment of newton’s second law
Mechanic is the branch of physics that is responsible for the study of the movement and balance of bodies in a system, within this can also be considered the bodies at rest. For the first case the scientist Isaac Newton considered the study of the movement of bodies, where he defines that any physical system which is subjected to different actions, as long as such actions are not nullified, will result in a change in the state of the body. The force is the magnitude that quantitatively measures the intensity, direction and direction of that interactions, having said that, if the summation of all forces of a system is different from zero, it can be concluded that the system will be in motion and therefore have an associated acceleration. Based on the above definition, was executed by the research group Design and Construction of Prototypes for Demonstration Experiments (DICOPED) in the design and construction of a prototype that allows to verify the Newton’s Second Law, looking to develop an autonomous, robust and low-cost prototype, that allows the use of the technology and tools present in the means, encourage and facilitate the teaching of basic concepts but no less important of physics to students of basic and higher education.

Prototyping for designers : developing the best digital and physical products
Prototyping and user testing is the best way to create successful products, but many designers skip this important step and use gut instinct instead. By explaining the goals behind prototyping - and demonstrating how to prototype for both physical and digital products - this practical book helps beginning and intermediate designers become more comfortable with creating and testing prototypes early and often in the process.

DISCOURS LÉGER SUR LES ORGUES À VENT VARIABLE
Bien plus tard, l'invention de l'harmonium est aussi venue de ce désir d'expression, deffets sonores: le but en était bien de pouvoir, avec un instrument à touches, jouer aussi souplement et aussi expressivement que sur un instrument à cordes ou à vent. Daniel Glaus, ancien organiste du Munster de Berne, a fait construire (avec les facteurs d'orgues Peter Kraul, Johannes Róhrig et Daniel Debrunner) un(e) «Forschungsorgel» (orgue de recherches) appelé(e) «winddynamisch» décliné en plusieurs prototypes. || s'agissait de travailler sur la pression et la quantité d'air utilisé pour obtenir cette dynamique du vent, et M. Glaus, avec ses acolytes, a lancé un projet de recherche en 1999, réalisant des prototypes au début des années 2000, jusqu'au Prototype Ill que l'on voyait à Berne qui date de 2008. Mais l'ennui est évident : si vous soufflez plus fort, votre instrument monte, et si vous baissez la pression, il descend, car les tuyaux d'orgues ne peuvent guère se compenser avec les lèvres ou les doigts. Linstrument de M. Glaus possède plusieurs manières d'influencer le vent: on voit sur les photographies au moins trois pédales « d'expression »; en outre, on a cherché à travailler sur la profondeur de la course des touches, sur des tirants de registres ou autres objets mobiles qui se manipulent de diverses manières, ou sur des appareils électriques agissant sur la vitesse de la soufflerie ; bref, une infinie variété de systèmes. Car l'expression doit être expressive et on n'aura jamais vu une musique classique devenir encore plus belle par usage de ces inventions: Ce piano possédait un registre de flÛte dont on pouvait modifier le son en enfonçant plus ou moins les touches. Le mécanisme à genou pour les flÛtes que l'on peut faire jouer plus fort sans que le ton ne monte n'est malheureusement pas exactement décrit. ll y avait probablement deux mécanismes: celui qui contrôlait la force du vent, et celui qui compensait les modifications de hauteur des notes. Certes, on ne peut pas prouver qu'il ait connu les registres à vent variable dans le style de Stein et de Späth, mais on constate que la facture d'orgues de sa région évolue fortement vers des nouveautés plus expressives et plus souples. -

P150 Translating Recommendations Into Clinical Decision Support: Cancerlinq Prototype Experience
Background The Guideline Elements Model (GEM) has been widely used to translate natural language clinical practice guidelines (CPGs) into clinical decision support (CDS) using a highly replicable, guideline-centric approach. A CPG recommendation-to-CDS translation process, which uses GEM-processed content to support an oncology rapid learning system (RLS) prototype, is examined here. Objectives To develop rules for a breast cancer-specific CDS prototype using GEM-processed guideline content. Methods We created five breast cancer patient scenarios with expert input from oncologists based on nine published CPGs. Using the Yale Center for Medical Informatics-developed GEM Cutter III editor, we parsed the narrative CPG recommendations into an XML-based, machine-readable format. GEM-processed content was then encoded into a Drools business rule management system to develop an integrated platform prototype for rules, workflow, and event processing. We used meta-tags to create value sets for key components of each recommendation by selecting terms from UMLS vocabularies, including SNOMED CT and LOINC. Results Forty-five recommendations spanning nine CPGs were processed and converted into Drools rules. We identified 138 decision variables and 91 actions within the selected recommendations. From these, we encoded 148 concepts associated with value set meta-tags and 238 decision rules. Discussion The level of difficulty required to encode the recommendations was directly related to the specificity, complexity, and decidability of each recommendation; there was significant variability among the recommendations. Implications for Guideline Developers/Users CPG developers may need new processes in order to optimise recommendations for incorporation into CDS systems.

A generalizable framework for urban building energy model archetype generation using k-prototypes mixed-data clustering
Developing building archetypes from urban data is essential for urban building energy modeling (UBEM), yet current approaches lack generalizability, particularly regarding categorical data. This paper compares k-means, k-medoids, and k-prototypes clustering using Zurich’s building registry to evaluate the impact of preprocessing and algorithm choice. Results show preprocessing had limited effect on clustering, while k-prototypes—capable of handling numerical and categorical data concurrently—produced practical, interpretable clusters. The method’s simplicity and robust handling of mixed-type data suggest k-prototypes can streamline UBEM archetype generation workflows.

A Word Sense Disambiguation Model for Amharic Words using Semi-Supervised Learning Paradigm
The main objective of this research was to design a WSD (word sense disambiguation) prototype model for Amharic words using semi-supervised learning method to extract training sets which minimizes the amount of the required human intervention and it can produce considerable improvement in learning accuracy. Due to the unavailability of Amharic word net, only five words were selected. These words were atena (...), derese (...), tenesa (...), bela (...) and ale (...). A separate data sets using five ambiguous words were prepared for the development of this Amharic WSD prototype. The final classification task was done on fully labelled training set using Adaboost, bagging, and AD tree classification algorithms on WEKA package.

Sperimentare, sviluppare e provocare: il prototipo come strumento del progetto
Nelle Scuole di Architettura, come il MIT - Massachusetts Institute of Technology - o l'ETH di Zurigo, la prototipazione fisica rappresenta unesperienza di didattica efficace, il metodo formativo si basa sull'\"imparare facendo\" e i laboratori costituiscono le \"officine\" in cui realizzare \"al vero\" l'idea architettonica (Paris, 2017). Nei Design-Build projects, sviluppati in tutto il mondo come strategia di architectural education, gli studenti sviluppano e costruiscono in scala reale vere e proprie strutture edilizie (Folic et al., 2016). In particolare, stimolo per la progettazione tecnologica la tassonomia proposta da Stan Ruecker in relazione alle Digital Humanities (Ruecker, 2015) che individua tre diverse categorie di prototipi a seconda dellobiettivo per cui vengono realizzati: experiment, development and provocation prototypes. Un team di docenti e studenti della Scuola di Architettura del Politecnico di Torino, in collaborazione con l'associazione culturale Atelier Mobile e l'artista Carlos Valverde, ha sviluppato una proposta di architettura effimera in grado di valorizzare uno spazio residuale della cittå di Torino all'interno del cosiddetto Bunker, un ex area industriale dismessa alla fine degli anni '80, situata a Nord della cittå di Torino.
