Latest Update (2nd November 2025):
In a historic moment for Indian sports, the Indian Women’s Cricket Team clinched the ICC Women’s Cricket World Cup title by defeating South Africa in a thrilling final. This victory not only marked a milestone in women’s cricket but also set new viewership records — the live audience peaked at over 190 million across broadcast and digital platforms.
This phenomenal rise in audience engagement highlights how trends in sports consumption are rapidly changing, with women’s cricket emerging as a mainstream spectacle. The integration of advanced AV technologies, immersive viewing experiences, and digital streaming innovations has played a key role in attracting diverse audiences and enhancing fan engagement across regions.
Projection mapping is a highly collaborative and layered process. It involves Creative vision – concept artists, storytellers, and designers building the idea. Technical expertise – 3D modelers, motion graphics artists, and programmers aligning content to real-world surfaces. Precision engineering – calculating projection angles, brightness, pixel pitch, and synchronization with sound and lighting. Team coordination – stage designers, content creators, and operators working together seamlessly. It’s never just “press a button” — it’s hours, days, sometimes months of planning, testing, and refining. The final show may last a few minutes, but behind it are countless hours of hard work. All the team member of this project respect and hats off to you for this wonderful job.

The Best way we can say that
Short-term AR/VR use can be engaging and even therapeutic (e.g., phobia treatment, training).
Long-term or heavy use may disrupt sensory integration, attention, and perception — exactly the “unsuitable for long term” experience which I have noticed (Alfa5 XR | The largest XR Sports center in the world).
Researchers recommend frequent breaks (every 20–30 min), limited daily exposure, and alternating with real-world sensory activities to keep the brain balanced.
La historia de la invención del altavoz es un relato fascinante de innovación, experimentación y transformación que ha influido profundamente en el mundo de la electroacústica, moldeando industrias como el entretenimiento, la comunicación, la arquitectura y la ingeniería.
1. Era Pre-Altavoz (Antes de 1870)La amplificación del sonido estaba limitada a métodos mecánicos:
-
-
2. Nacimiento del Concepto de AltavozSe usaban megáfonos, gramófonos y trompetas acústicas.
Se empleaban bocinas acústicas en los primeros fonógrafos.
📌 1877 – Thomas Edison y el Fonógrafo
El fonógrafo de Edison usaba un diafragma y una aguja para reproducir el sonido mecánicamente.
No había amplificación eléctrica, por lo tanto, el sonido era muy débil.
📌 1898 – Oliver Lodge
3. Primeros Altavoces Prácticos (Principios del Siglo XX)Desarrolló las primeras teorías sobre la reproducción electromagnética del sonido.
📌 1921 – Rice y Kellogg (General Electric)
Inventaron el altavoz dinámico de bobina móvil.
Esta es la tecnología principal que aún se utiliza hoy.
Fueron los primeros en usar una bobina electromagnética y un diafragma cónico para producir sonido amplificado.
📌 1925 – Patente del Altavoz Moderno
4. Adopción Comercial e InnovacionesChester W. Rice y Edward W. Kellogg patentaron el altavoz electrodinámico moderno.
📌 1926–1930s – Revolución del Sonido en el Cine

What is BIM and how it's different then CAD?
BIM stands for Building Information Modeling. It's a process that involves creating and managing digital representations of physical and functional characteristics of places. In simpler terms, BIM is a digital tool used in architecture, engineering, and construction industries for designing, visualizing, simulating, and managing building projects throughout their lifecycle.
BIM differs from CAD (Computer-Aided Design) in several ways:
Information-rich: While CAD primarily deals with 2D or 3D geometric representations, BIM goes beyond by incorporating additional information such as spatial relationships, geographic information, quantities, and properties of building components. This richer data allows for better decision-making throughout the lifecycle of a building.
Lifecycle management: BIM encompasses the entire lifecycle of a building, from conceptualization to demolition. It facilitates collaboration and coordination among various stakeholders including architects, engineers, contractors, and facility managers throughout the design, construction, and operation phases.
Interoperability: BIM encourages interoperability among different disciplines and software platforms. It enables seamless integration of various building components and systems, fostering better coordination and communication among project teams.
Simulation and analysis: BIM enables the simulation and analysis of various aspects of a building such as structural integrity, energy performance, lighting, and HVAC systems. This helps in optimizing design decisions and improving the overall performance of the building.
Visualization: BIM provides advanced visualization capabilities, allowing stakeholders to visualize the building in 3D and even experience virtual walkthroughs. This aids in better understanding and communication of design intent.
Overall, while CAD focuses primarily on creating geometric representations, BIM provides a more comprehensive approach by incorporating rich data and facilitating collaboration throughout the lifecycle of a building.
Thank you @Kelly Smith, for giving this easy to understand roadmap, useful for anyone desirous of attaining their certification goals. A quick tip from me to all who are preparing for their CTS - do reach out to others who may be preparing for their certification for learning collaboratively, or even those already certified to learn from their experience of having gone through the whole process!
Simples my tips for CTS.
1. Follow the Question properly.
2. Don't get hurry to give answers .
3. Flag the Questions in which you get confused.
4. I finished my exam in 1 hour. But take 2 hour to answer flag questions. Utilize full 3 hours of exam.
5. CTS is not only a exam or certification. Its about hows your attitude towards industry and it's practice you want follow.
6. So don't get nervous about exam. If you fails it's not mean you don't know anything. Try again and again. Is still have problem our master Gopal sir is always their to help you.
7. If anything resisting or confusing you from the language point then we have world wide volunteer team who can explain you engineering terms in simple language.
8. After CTS please use the standard as much as possible. Because for that only we are connected to eachother.
