Boost Business Efficiency with Professional Data Entry Services
In today’s digital-first world, businesses generate and handle massive amounts of data every day — customer records, sales data, inventory logs, survey results, and much more. But raw data has no value unless it is well-organized, accurate, and easily accessible. That’s where professional data entry services come in.
By outsourcing data entry tasks to experts, businesses can streamline operations, reduce manual errors, and improve overall efficiency — while focusing their internal resources on core activities like growth and customer engagement.
What Are Data Entry Services?
Data entry services refer to the process of converting information from various formats (handwritten, scanned, PDF, image, or audio) into structured, digital formats such as Excel sheets, CRM databases, or cloud storage systems. This work may be done online or offline, manually or using automation tools, depending on the client’s requirements.

based on assumption that failure of such a weld is by shear on the
effective area whether the shear transfer is parallel to or
perpendicular to the axis of the line of fillet weld. In fact, the
strength is greater for shear transfer perpendicular to the weld axis;
however, for simplicity the situations are treated the same.最新版美国威斯康星大学河城分校毕业证（鲍奥搁贵毕业证书）原版定制

Velocite aerodynamics consulting
- 1. Velocite Aerodynamics Consulting CFD Simulations and Design
- 2. Examples of aerodynamic design Aero Not aero
- 3. Why consider aerodynamics? Functional benefits ● reduced drag ● improved handling ● improved brake cooling Business benefits ● better marketing story ● more OEM wins ● unified design language ○ reduced tooling costs ○ reduced part count ● create unique products
- 4. What do we do? ● Use computational fluid dynamics (CFD) to simulate external airflow over an object ○ Bike, brake, wheel, handlebars, fork, etc. ● Give advice and guidance on aerodynamic design ○ Is your design aero? We can make it so. ● Provide aerodynamic designs ○ Do you need a new aero product? We can design it.
- 5. Computational Fluid Dynamics (CFD) What is CFD? ● in aerodynamics, CFD delivers visual and numerical analysis of airflow around the object ● Unlike wind tunnel studies, CFD allows visualization of airflow and makes rational aerodynamic design possible
- 6. CFD versus wind tunnel CFD ● visualization of airflow ● used for design and development ● results not dependant on external conditions ● in Velocite’s case, results also not dependant on problem or operator ● good for marketing in the bicycle industry ● more expensive Wind tunnel ● used for verification of assumptions or design, not for development ● results depend on operator, experiment setup, day to day conditions, wind tunnel setup ● faster results ● great for marketing in bicycle industry ● cheaper (as used by the bicycle industry)
- 7. Who uses CFD? Since the 1970’s everyone in aerospace industry relies on CFD for primary design and development
- 8. Velocite CFD versus others Velocite ● Lattice-Boltzmann with LES turbulence model ● transient flow simulations Complex, computationally much more demanding. Not possible to run on a workstation. Other ● Navier-Stokes with K-ε → DES models ● generally steady state simulations Much simpler and computationally less demanding. Workstation level.
- 9. Examples Lattice-Boltzmann LES, transient. Velocite standard Navier-Stokes K-ε, steady state. Industry standard
- 10. Example Airflow detail: front brake location Rotating wheel simulation: 42 km/h @ 12 degrees angle of attack. 132 million cells, 20 thousand time steps. Front view Rear view
- 11. Example Airflow detail: short conclusion ● Layer of air adheres to the surface of the wheel and has direction vector that follows the rotational vector of the wheel ● Bulk airflow vector is aligned with the apparent wind direction ● High air pressure is observed on the front faces of the fork - this is especially significant at yaw Conclusion: brake shape and mounting location or integration impacts the overall bicycle aerodynamics
- 12. More examples: Velocite YouTube channel ● Three spoke wheel simulation ○ http://youtu.be/Qb9VkYOdCBw ● Airflow around water bottles: ○ http://youtu.be/g08s7hR70ok ● Velocite RT50 wheels ○ http://youtu.be/mGGm1gEJd8U ● Ahmed body validation example ○ http://youtu.be/2I0t5FHKHYc
- 13. How accurate or reliable is our CFD? ● We use custom made software developed for Velocite by a team of scientists at The University of Geneva, Switzerland ● Velocite CFD expertise was developed through our past and current work with: ○ Acer Computers ○ NARL NCHC (National Center for High Performance Computing) division ○ NCKU (National Cheng Kung University) in Tainan
- 14. Advantages of Velocite method ● Much higher resolution ○ allows better design decisions ● More realistic results ○ not idealized, nothing is hidden or smoothed over ● Correctly simulates downstream airflow ○ can determine how design changes impact the rest of the bicycle ● Can use actual physical 3D model ○ no separate meshing or preparation step
- 15. How can our service benefit you? We can help you design your new world class aero product If you already have a product, but no data we can help you validate your design We can make the all-important CFD simulation images, videos and data Design Validation Marketing
- 16. Velocite CFD offer ● Simulate 3D airflow around any number of parts, including rotating wheels, or cranks ○ variable airspeed, variable angle of attack, variable rotational, or periodic velocity, as required ○ Simulation runs on our in-house compute cluster in Taiwan ● Provide detailed aerodynamics analysis and design recommendations, numerical data, images and videos as required ● Competitive pricing that can suit any design and development budget
