5G in Space

CADDZOOM

The fifth generation of mobile communication is on its way to bridge the numerous gaps by its preceding technologies. Most of the network issues arise when people wish to watch 4K videos, video chat or when they want to interact with the different IoT devices.

Similar problems occur in the satellite communication mechanism. As more and more satellites are launched into the space, they face issues in transferring data. The 5G technology can easily resolve such issues.

  • 5G uses high frequency for establishing communication between different devices.
  • These frequencies are in the range of 30 to 300 GHz.

Millimeter Wave Satellite

To make the communication better, researchers from the European Space Agency (ESA) are making efforts to develop satellites that will communicate on millimeter-wave frequencies. These satellites are named as W-Cube. Some of their features are:

  • Communication devices installed in these satellites will test and use the 75 GHz frequency band.
  • The body of these satellites will be based on Reaktor’s Hello World CubeSat platform.
  • They will weigh less than 5kg.

Finland based Reaktor Space Lab and the VTT Technical Research Centre will develop these satellites. The signals transferred by them will be observed at the measurement station in Graz, Austria. This technology will provide a unique opportunity to achieve high expertise in the field of telecommunication in the space.

Course on HVAC and Job Opportunities

CADDZOOM

HVAC refers to the technology that deals with heating, ventilation, and air conditioning for indoors and vehicles. The branch of HVAC system design is a sub-discipline of mechanical engineering which is based on the principles of thermodynamics, heat transfer, and fluid mechanics.

Rapid advancement in the technology increased the need for more professionals in this field. The HVAC technicians play a vital role during the installing and servicing the systems. These professionals control the air temperature and its quality in a building.

Aspiring candidates who wish to make a career in the field of HVAC can take a course through certification, diploma, associate’s or bachelor’s degree programs. Different levels of HVAC courses have similar curriculum with course durations ranging from 12 months to 2 years. The HVAC course covers topics such that:

  • Electrical Heating
  • Power and Resistance
  • Water Volume
  • Pollution
  • Green Technology
  • Cost Efficiency

Heating and Air Conditioning Training

A few years ago, most of the heating, ventilating and air conditioning technicians received on-the-job training. However, with the rapid advancement in the technology, the technicians are now offered training through classroom study, internships and apprenticeships.

Candidates who receive these training learn how to install, repair and maintain ventilation, heating, refrigeration and air conditioning systems. While some comprehensive training programs include all of these systems, other may focus only on some specific areas.

Highlights of the HVAC training:

  • It is usually a combination of classwork and hands-on training.
  • Students may explore topics like electrical design, commercial heating, circuitry, and air conditioning systems.
  • They may also learn principles of system design and refrigeration.

HVAC can provide some amazing job opportunities for the candidates who wish to make a career in this field. HVAC is a thriving career and gives a great job satisfaction for people who are interested in this field. Some of the opportunities in HVAC are:

  • HVAC Service Technicians
  • HVAC Mechanical Engineers
  • Project Managers
  • HVAC Service Managers
  • Sales and Administrative Coordinators
  • HVAC Control Technicians
  • Maintenance Supervisors
  • Quality Assurance Specialists
  • Executive Level Professional Managers

HVAC job opportunities are highly demanding and lucrative as people are making comfort as their priority. Engineering candidates can easily grab these job roles soon after completing a short-term or a long-term course in HVAC. The best part of the HVAC profession is, it adds comfort to people’s lives.

Fourth Industrial Revolution: How Engineers can Stay Prepared

CADDZOOM

Like the first industrial revolution, which introduced the use of steam in the production industry. The second which included electric power, and the third that introduced IT, the fourth industrial revolution is set to bring new changes in the field of technology. Although it is difficult to define its possible alignment with the engineering world, we can expect some drastic changes in the events and be prepared to embrace them.

Here are five ways in which the engineers can prepare themselves for it:

  • They need to be more attentive and constantly upgrade their skills to stay competitive.
  • Engineering professionals have to look for ways that include low production costs and high-profit returns.
  • It is important for them to stay continuously updated with the technology.
  • The engineers need to stay open to the changing communication mechanisms and technology.
  • The revolution may change the ways in which work gets done, therefore staying flexible towards work is important for the engineering professionals.

Innovation Engineering on its Way

CADDZOOM

Today’s thriving engineering technologies have been surprising us constantly. And, with the changing technologies, we can still expect how things change across different technology domains and industries. Here are ten most groundbreaking innovations in engineering that gives it a new definition.

3D Printing: The computers here converts the digital image of the model into a tangible physical product. The technology can print almost anything by laying layers of materials with the help of 3D printers.

Floating Train tracks: Researchers are now working to develop steel platforms on which trains can pass. These will have flexible bearings that will let the light rail tracks stay in a line. 

 

A Roof that closes like a Camera: One of the Atlanta’s newest stadium, now has a set of eight 500 ton steel petals that unfurl 200 feet above the ground. They can shut quickly in nine minutes shielding the players and the fans from the weather outside.

 

Replicating the Robot Arms: Robotic arms can now reassemble clones for itself and is cheaper than most of its market competitors.

AquaRefining: The method uses an electrochemical system to dissolve the Lead at room temperature without smelting harmful emission which occurred in the traditional methods.

Genetic Code printing: The new Digital-to-Biological Converter is now able to print genetic code following the digital instructions.

Synthetic Spider Silk: This fabric is developed artificially using yeast and is later spun into fabric using machines. These are the renewable protein-based fibers now available as a merchandise.

Thin Rail Roller-coaster: Designers are now using durable and less amount of steel to develop the Raptor Track roller coaster which easily fit into the intended spaces and offers a highly smooth ride.

Floating Wind Farm: Scotland is now using a floating wind farm to generate power from wind. Although they are currently close to the seashore, researchers are working to install them at farther distances where the winds are strong.

Underwater Snake Bots: The technology can be stationed on the seabed to repair infrastructure damages.

Nasa’s 2020 Mission: The Mars Helicopter

CADDZOOM

NASA is working on its next mission to launch a helicopter to the Mars. The project is scheduled in July 2020. The project is in the development phase at NASA’s Jet Propulsion Laboratory (JPL) since the year 2013. Some of its features are:

  • The Mars helicopter will weigh around 1.8 kg and will be designed to operate in the planet’s extremely thin atmosphere.
  • Earth, being several light minutes away, the helicopter will be highly autonomous.
  • It will receive and operate on the commands from the ground to share information.

The Mars helicopter is a high risk- high reward project and if successful, it may open new opportunities in interplanetary exploration.
