Projects by Joshua Sylvain de Miranda, grade 10 at Tyger Valley College and Este-Lize Graham grade 10 at Hoërskool Menlopark, both in Pretoria, were selected to exhibit at the OKSE2F while competing against 600 other participants at the Eskom Expo for Young Scientists International Science Fair (ISF) in October 2017. Joshua won first prize/gold medal in the chemistry category while Este-Lize won second prize/ silver medal in the biology category.

Waheed Amanjee, a grade 11 learner from Creston College in Port Shepstone won second prize/ silver medal in the engineering- energy category at the science fair. He was selected for his impressive research entitled: FootBit: Step into the Future. His project is inspired by the need for efficient renewable energy sources worldwide. There is a dire need for innovative and efficient renewable energy sources so more people can have access to electricity. The problem is that most present forms of renewable energy are reliant on sources that humans are not in control of and are usually very expensive.

The device that Waheed came up with is simple, effective and economical. The range of energy harvested on the shoe sole, is able to power a 50V LED light, Arduino and charge a battery. “This invention will assist in reducing the human species’ carbon footprint and place Africa on the forefront of innovation in renewable energy.” says Waheed.

In March this year, Waheed was selected to represent Africa at OKSE2F after taking first place in the Innovation Category at the Buskers Festival in Zambia.

For his project titled, “Fire Redundancy Effect of Non-toxic Chemicals”, Joshua aimed to develop a flame retardant that would delay the spread of fires in informal settlements. “The research involved investigating the variables that affect the behaviour of fire, the dangers and obstacles that fire departments face when responding to fires in informal settlements and going into informal settlements to investigate building materials used and how flame retardants could delay the spread of fires,” says Joshua. Joshua determined that using a solution of Borax and Boracic Powder as a flame retardant on building materials would delay the spread of fires.

The project Este-Lize exhibited at  OKSE2F is entitled “Can laser light enhance cell division?”, and seeks to explore the effects of using a continuous wave laser to irradiate TZM-bi cells at a fluency or power density of 5J/cm2. “The irradiated cells were compared to the non-irradiated cells of the control group to determine if laser interaction with cells can enhance or inhibit cell division. The outcome of this project will provide a clearer understanding of the effects that lasers have on cellular processes taking place within cells at in-vitro level,” says Este-Lize.

OKSE2F aims to bring together high school students from all around the world to present their scientific and technological researches and to make them share their culture. To this end, young people are invited to exhibit their research projects in the fields of physics, chemistry, biology, engineering, energy, mathematics-computer and robotics.

“Every year we are impressed by the ingenuity shown by the participants at Eskom Expo. Their commitment to finding innovative solutions to society’s most pressing problems such as sustainability is admirable. Eskom Expo recognises and rewards their contribution to the global knowledge base,” says Executive Director of the Eskom Expo, Parthy Chetty.

OKSE2F and the Eskom Expo are both organisations that invite young people to present their projects on their platforms and to make social and cultural exchanges with their peers from all over the world. The science fair took place from 4 – 10 June.

“At Eskom we have a huge need for talented scientists and engineers and by supporting the Eskom Expo we are able to invest in developing a pipeline of talented technical specialists. The Eskom Expo isn’t just about cultivating an interest in the sciences but through strategic support we encourage young scientists to pursue their interest at a tertiary level. This long-term vision means that in a few years’ time these scientists will begin to serve South Africa in areas beset by a scarcity of skills,” says Thava Govender, Eskom Group Executive: Transmission and Acting Group Executive Sustainability & Risk.

Auto rivals team up for connected car demo

Rivals BMW, Ford and Groupe PSA, maker of Peugeot and Opel cars, have teamed up with the 5G Automotive Association (5GAA), Qualcomm Technologies and Savari for Europe’s first live demonstration of C-V2X direct communication technology operating across vehicles from multiple auto manufacturers.

The live demonstration also featured a live showcase of C-V2X direct communication technology operating between passenger cars, motorcycles, and roadside infrastructure. C-V2X is a global solution for vehicle-to-everything (V2X) communication in support of improved automotive safety, automated driving and traffic efficiency.

The demonstration exhibited the road safety and traffic efficiency benefits of using C-V2X for Vehicle-to-Vehicle (V2V) collision avoidance, as well as Vehicle-to-Infrastructure (V2I) connectivity to traffic signals and Traffic Management Centers (TMC). C-V2X was operated using real-time direct communications over ITS spectrum and demonstrated its ability to work without cellular network coverage, and underscores its commercial readiness for industry deployment as early as 2020. Superior performance and cost-effectiveness compared to other V2X technologies, along with forward-compatibility with 5G, make C-V2X direct communications a preferred solution for C-ITS applications.

Six demonstrations were shown including: Emergency Electronic Brake Light, Intersection Collision Warning, Across Traffic Turn Collision Risk Warning, Slow Vehicle Warning and Stationary Vehicle Warning, Signal Phase and Timing / Signal Violation Warning and Vulnerable Road User (pedestrian) Warning. The vehicles involved included two-wheel e-scooters provided by BMW Group, and automotive passenger vehicles provided by Ford, Groupe PSA, and BMW Group, all of which were equipped with C-V2X direct communication technology using the Qualcomm® 9150 C-V2X chipset solution.  V2X software stack and application software, along with roadside infrastructure, were provided by industry leader, Savari.

C-V2X is globally supported by a broad automotive ecosystem, which includes the fast growing 5GAA organization.  The 5GAA involves over 85 global members comprised of many leading automakers, Tier-1 suppliers, software developers, mobile operators, semiconductor companies, test equipment vendors, telecom suppliers, traffic signal suppliers and road operators.  

Cellular modems will be key to the C-V2X deployment in vehicles to support telematics, eCall, connected infotainment and delivering useful driving/traffic/parking information. As C-V2X direct communication functionality is integrated into the cellular modem, C-V2X solutions are expected to be more cost-efficient and economical over competing technologies, and benefit from accelerated attach rates.  C-V2X direct communication field validations are currently underway in Germany, France, Korea, China, Japan and the U.S.

C-V2X currently stands as the only V2X technology based on globally recognized 3rd Generation Partnership Project (3GPP) specifications, with ongoing evolution designed to offer forward compatibility with 5G.  C-V2X also leverages and reuses the upper layer protocols defined by the automotive industry, including the European Telecommunications Standards Institute (ETSI) organization. C-V2X includes two complementary transmission modes: 

  • Direct communication as shown in this demonstration for V2V and V2I use cases
  • V2N network communication, which leverages mobile operators for connectivity and delivers cloud-based services, including automated crash notification (ACN, as mandated by eCall), hazard warnings, weather conditions, green light optimal speed advisory (GLOSA), parking spot location, and remote tele-operation to support automated driving, to name a few.

“This demonstration builds on the successful C-V2X showcase we organised with our members Audi, Ford and Qualcomm in Washington DC in April, said Christoph Voigt, Chairman of 5GAA.

“We are excited to witness the growing momentum behind this life-saving technology and to see our members working together to deploy C-V2X, and to make it hit the road as soon as possible.”  

“The BMW Group introduced the first C-ITS use cases already in 2013 with the market introduction of the BMW i3. Today most of envisaged C-ITS use-cases are already institutionalized. With the implementation of C-V2X, the BMW Group accomplishes the last set of the puzzle with a practical path to C-ITS showing quick benefits,” said Christoph Grote, Senior Vice President Electronics, BMW Group. 

“With its ability to safely and securely connect vehicles, along with its evolution into 5G, C-V2X is integral to Ford’s vision for future transportation in which all cars and infrastructure talk to each other,” said Thomas Lukaszewicz, Manager Automated Driving, Ford of Europe. “We are very encouraged by preliminary test results in Europe and elsewhere which support our belief that C-V2X direct communications has superior V2X communication capabilities.”

“We’re moving forward with seamless communication between cars and their environment for enhancing road safety, as well as our customers’ safety,” said Carla Gohin, Group PSA’s Vice President for Research and Advanced Engineering. “Following the first European C-V2X direct communications demonstration we hosted with Qualcomm Technologies last March, we’re pleased to work with leading automotive and technology companies today to highlight that C-V2X interoperability is a reality.” 

“This demonstration of interoperability between multiple automakers is not only another milestone achieved towards C-V2X deployment, but also further validates the commercial viability and global compatibility of C-V2X direct communications for connected vehicles,” said Enrico Salvatori, senior vice president & president, Qualcomm Europe and MEA. “We look forward in continuing to work alongside leaders in the automotive industry, like the 5GAA, BMW Group, Ford, Groupe PSA and Savari, to help advance the automotive industry’s shift towards a safer, connected and more autonomous future.” 

“As one of the V2X pioneers, our company is extremely pleased to continue to help enable the next step in the V2X revolution that we helped start back in 2008,” said Ravi Puvvala, CEO of Savari. “For the last year and a half, the Savari team has worked diligently alongside the dedicated C-V2X engineers in the 5GAA partnership. The resulting string of increasingly impressive demonstrations is continuing to convince the world that C-V2X will soon be deployed around the world.”

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entires via Twitter, so please don’t enter through the comments section of this article.)

2. Tell us on Twitter, via @GadgetZA, mentioning @Takealot in your posting, how many Watts the Poster Heater consumes.

cleardot.gif3. The competition closes on 31 July 2018.

4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.
