I need a full set of 2-D manufacturing drawings for four plastic plate designs: one flat rectangle with two holes, the same rectangular plate doubled with a single 45° fold between each half, one flat rectangle with four holes, and one flat rectangle with six small holes and one large hole. From these three foundations I have ten straightforward variants of size or hole-pattern changes, so the total package comes to fourteen individual plates. Each drawing must show finished outside dimensions, hole diameters, centre-to-edge/centre-to-centre measurements, and, in the folded part, the precise bend line. A simple note that standard workshop tolerances apply. Deliverables (one file per plate): PDF with clear dimensions, title block, and A3/Letter sheet size Please include an initial draft for my review, one revision cycle for each shape, and the final locked-down drawing set. Autodesk Inventor, Fusion 360, SolidWorks, or any equivalent CAD tool is fine.

I’m a complete beginner in SketchUp and need focused coaching that shows me just the essentials for exterior structures. My goal is to model basic building shells so I can later add scaffolding around them; interior details, windows, and other features are not required. Here’s exactly what I want to master: • Building and aligning exterior walls • Creating and adjusting roofs (simple pitched or flat) • Organizing the model so it’s ready for separate scaffolding work later Format & schedule – Live lessons only, delivered online via video call (Zoom, Meet, or similar). – You’ll demonstrate each step, then watch me replicate it and correct any mistakes in real time. – Short homework exercises between sessions would be helpful to reinforce the concepts. Ideal tutor Someone patient, clear, and experienced with SketchUp’s core drawing, push/pull, grouping, and component tools—especially for architectural exteriors. Experience teaching beginners is a big plus. Deliverables 1. A series of live online sessions (propose a session count and duration). 2. Any practice files or reference guides you typically provide students. 3. A final review session confirming I can independently create an exterior shell with walls and a roof. If this straightforward, exterior-only training fits your expertise, please outline your teaching approach, estimated hours, and availability.

I would like a full TFET study carried out in Cogenda Visual TCAD that covers both 2-D and 3-D device representations. My end goal is to arrive at a structure—and a small demonstration circuit—whose operating point clearly illustrates ultra-low power consumption. Here’s what I need from you: • Build the TFET geometry in the tool, choose appropriate materials and doping profiles, then sweep critical design parameters until the device meets a low-power operating target (sub-threshold swing and leakage will be the key figures I’ll look at). • Run complete electrical simulations in 2-D first, then extend the validated setup to 3-D so I can compare dimensional effects. • Supply all Cogenda project files, meshes, command scripts, and export any plots of I-V curves or energy band diagrams that you generate. • Summarise the methodology and findings in a concise report so I can reproduce or modify the work later. I already have Visual TCAD installed, so if you keep the workflow native to the software—using the built-in mesh generator, solver settings, and visualisation tools—I will be able to verify everything quickly. Acceptance criteria – 2-D and 3-D simulation files open without errors in the current release of Cogenda Visual TCAD. – Report shows at least one TFET operating point that achieves noticeably lower static power than an equivalently sized MOSFET baseline. – All key steps (geometry, meshing, physics models, bias conditions) are documented. If this is clear and feasible for you, let me know how soon you can deliver the initial 2-D results so we can iterate.

Project Title Structural Analysis of a Building Using the Finite Element Method (FEM) Based on a 3D Model Developed in Revit Description Within the framework of an academic project, I aim to carry out a structural analysis of a building using the Finite Element Method (FEM) with the software Abaqus. I currently have a 3D model developed in Revit, derived from a three-dimensional survey, which serves as the geometric basis for the numerical simulations. The objective is to evaluate the structural behavior of the building in its initial state, as well as its response under seismic loading. Scope of Work The selected freelancer will be responsible for: Model Preparation for Abaqus Geometric simplification of the 3D Revit model Cleaning and adaptation of the model for FEM analysis Selection of the appropriate modeling approach (solid, shell, or mixed) Definition of Mechanical Assumptions Material properties Boundary conditions Behavioral assumptions adapted to existing buildings Numerical Simulations Initial state analysis under permanent loads (self-weight) Seismic analysis (equivalent static or dynamic approach, to be defined) Extraction of results: displacements, stresses, and critical zones Results Interpretation Critical analysis of the structural behavior Identification of vulnerable zones Expected Deliverables Fully functional Abaqus model (.cae) Results of the different simulations Explanatory technical report, including: Model preparation steps Adopted assumptions Calculation parameters Illustrations and screenshots from Abaqus Report written in English or French Required Profile Engineer or researcher in civil engineering / structural mechanics Proven proficiency in Abaqus Experience in FEM analysis of existing buildings Ability to clearly explain and justify methodological choices (academic context) Additional Information Approximate building area: 310 m² Academic-oriented project, requiring methodological rigor and clarity

Our YouTube channel is expanding into a new series of Tamil nursery-rhyme videos and I need a skilled 3D animator to bring each song to life. Every episode will run 3-5 minutes and must feel bright, playful, and unmistakably cartoonish—think bold colors, expressive faces, and exaggerated motion that keeps toddlers glued to the screen. I already have a couple of recurring mascots; they’ll appear throughout the series. For the remaining roles you’re free to design brand-new, culturally resonant characters that fit the rhyme’s story. I’ll supply the lyrics, audio track, and reference sketches for my existing cast, then give clear notes on mood and pacing for each rhyme. You’d be handling the pipeline end-to-end—modeling, rigging, animation, lighting, and final render—so comfort with tools like Blender, Maya, or 3ds Max (plus After Effects or Premiere for the final cut) is essential. Lip-sync to the Tamil vocals, basic sound effects, and a simple two-line subtitle burn-in round out the polish I’m after. Deliverables per episode • Storyboard & character sheet for approval • Fully animated 3D video (1920 × 1080, MP4, 30 fps) synced to the supplied Tamil track • Source project files and textures Once each milestone is approved, we’ll roll straight into the next rhyme so the workflow stays smooth. If you love kids’ content and have a reel that proves it, let’s build this series together.

Necesito a alguien que transforme logotipos en archivos vectoriales listos para mecanizado CNC de moldes de aluminio destinados a parches y llaveros de plastisol. No se trata solo de “vectorizar”: el resultado debe ser fabricable sin ajustes adicionales en taller. Requisitos técnicos clave • Vectores cerrados y limpios, entregados en DXF y SVG. • Escala real en milímetros. • Detalles menores a 0,4 mm eliminados o fusionados. • Radio interno mínimo de 0,5 mm. • Paredes de color bien definidas con separación aproximada de 0,5 mm para las cavidades del molde. • Curvas suaves con pocos nodos para optimizar el fresado. • Compatibilidad directa con Aspire (preferente) y, de ser posible, Fusion 360. Flujo de trabajo Envío el logotipo (generalmente PNG o JPG). Tú devuelves el archivo DXF/SVG conforme a las especificaciones. Cuando la colaboración funcione bien habrá trabajo cada semana. Para evaluar tu propuesta, indícame: 1. Ejemplos de DXF que ya hayas usado en CNC. 2. Tu precio por cada diseño. 3. Tiempo estimado de entrega habitual. Si cumples con la simplificación máxima manteniendo los rasgos principales y conoces Aspire, podemos empezar de inmediato. ¡Espero tu portafolio y condiciones!
