My current Unreal Engine project is stalled because two key gameplay systems are failing. First, character movement no longer responds crisply to player input. Inputs are occasionally dropped or delayed, and the pawn does not accelerate, decelerate, or change direction ...follow what was fixed. • Share the updated project files for verification and testing. If you prefer to convert any of these blueprints to C++ for performance or readability, let me know; I’m open to improvements so long as everything compiles and runs in 5.3. Acceptance criteria: after your fix, my QA checklist—built around input latency tests and dummy-enemy hit detection—must pass without regression.

...validate every screen, workflow, and edge-case before it reaches users. You will take full ownership of quality assurance—planning the test strategy, running focused cycles, and guiding me on anything that could compromise stability or user experience. The exact blend of techniques is up to you. If a deep manual sweep is the fastest way to uncover usability flaws, let’s do it. Should automated regression or performance stress-tests add real value, I’m happy to lean on tools such as Appium, Selenium, or JMeter. Whether the build targets iOS, Android, or both, your process should fit naturally into the current development rhythm.

The work will cover data preprocessing and basic exploratory data analysis to understand sensor behavior and engine degradation patterns. Rolling and derived features will be created to improve model performance, followed by an engine-wise train/test split to ensure proper evaluation. A Linear Regression model will be implemented as a baseline, along with a Random Forest or XGBoost model for improved prediction performance. Models will be evaluated using MAE and RMSE, with basic RUL-focused error analysis to understand prediction accuracy.

Scope at a glance • Review existing electrical design, spot weak points, propose improvements • Develop or optimise the control software (C/C++, Python, or ladder logic—whichever best fits) • Support bench-top testing and provide concise build notes so our technicians can reproduce your work Additional Details: A motorized (24VDC M+Encoder) toothed belt linear guide with pneumatic gripper combined with a paternoster system using a 230 VCA motor and 14 sensors. Overall setup involves approximately 16 I/O. Deliverables will be considered complete when the updated schematics, compiled code, and a short commissioning guide are handed over and our in-house tests pass without errors. Let me know your preferred toolchain ...

I will supply clear dimensional sketches of the steel component along with the static load distributions that it must withstand. From those hand drawings I need you to recreate the geometry in your preferred FEA-capable package—ANSYS, SolidWorks Simulation, Abaqus, or another fully-licensed tool you trust—mesh it appropriately, and run a complete linear static analysis. The finished work should give me: • A clean CAD model that reflects every dimension shown in my sketches. • Screenshots of the mesh and boundary-condition setup so I can see exactly how the loads and constraints were applied. • Result plots for stresses, displacements, and load concentrations, with the critical zones clearly marked. • A concise written report (PDF) summarising ...

I have a clean quantitative dataset and need the key findings distilled into a concise two-page report. Using SPSS, please run a t-test, one-way ANOVA, and a standard multiple regression, then translate the output into plain-language insights that a non-statistician can follow. The report should: • Summarise the rationale, assumptions checked, test statistics, effect sizes, and exact p-values. • Highlight practical meaning of the results, not just significance. • Include any relevant SPSS tables or graphs pasted neatly (they may sit in an appendix if space is tight). Deliverables 1. .sav file with syntax or a reusable .sps script showing every step. 2. Two-page PDF or Word document containing the narrative interpretation. I consider the job complete when ...

...canonical structure that the rest of the application should depend on. From there, the work becomes controlled: — stabilize tenant boundaries and persistence — align APIs with the canonical model — migrate existing relationships safely — reconnect documents, forms, and configuration workflows — eliminate duplicated logic rather than adding another abstraction layer — protect critical flows with regression tests — leave the architecture understandable for whoever works on the system next I am particularly interested in projects like this because they require more than writing code. They require understanding the operational system behind the code and deciding what should remain, what should disappear, and what must become the permanent ...

...Building façade • Large floor-to-ceiling windows that read as continuous glass bands • Strong, straight lines and a minimalist material mix (think smooth render, metal, or concrete accents) • Night-time lighting concept that highlights the geometry without adding visual noise 2. Outdoor landscape layout • A generous green lawn as the anchor • Discreet water features (a linear reflecting pool or slim rill that echoes the façade lines) • A relaxed seating area that feels integrated, not tacked on—ideally shaded and oriented toward the water element 3. External boundary wall • Same modern language as the house, with privacy in mind but no heavy ornamentation • Cohesive lighting ...
