Emission Sampler Wireless Communication

Janjua, Ghalib (Principal Investigator) Ayub, Ahmad (Co-investigator)

This is £5000.00 Student Innovation Voucher Award.

Technological advances in wireless communication have paved the way for the development of miniaturized, low-cost, and power-efficient wireless networking devices. The extensive demand for internet of things applications have created new networking challenges, which have encouraged the development of a new paradigm of networking devices. The design of a networking device is influenced by factors like scalability, energy consumption, and environment and depends on the applications. In a wireless sensing device, the main activities are sensing, processing, and communication, and out of these behaviours, most of the energy is spent on communication purposes. Energy conservation is thus a dominant factor in wireless networking devices. Routing strategy selection is very important for the ensured delivery of transmission packets.

The LoRa technology provides long-range coverage and extremely low power consumption by using Chirp spread-spectrum modulation techniques. A lot of work has been done on LoRa technology since its emergence with the potential to revolutionise modern low-power communication. This project is providing a comparison of state-of-art communication technology and the implementation of a unique solution for lora based drone communication system for Emission sampler devices.

Emission Sampler

Janjua, Ghalib (Principal Investigator) Ayub, Ahmad (Co-investigator)

This is £5000.00 Standard Innovation Voucher Award

A greener environment is essential for future sustainable development. It is vital to phaseout greenhouse gas emissions from maritime transport to be a cost-effective way for international trade and development. As a pathway towards decarbonizing the shipping industry, port authorities and shipowners are currently required to monitor and control maritime vessels’ emissions to allow moving forward a clean energy transition and tackling climate change. The main aim of this project is to develop an emissions sampler circuit to provide real-time measurements of CO2 gases emissions to help the port authorities to monitor and regulate the level of harmful emissions in maritime ecosystem. A sampler circuit has been designed based on non-dispersive infrared sensor (NDIR) technology and interfaced with a programmable microcontroller and indicator devices to detect and monitor the range of CO2 concentrations within a certain environment. An experimental prototype has been developed and tested to validate the sampler circuit, demonstrating the effectiveness of the NDIR selected sensor technology in providing accurate measurements of CO2 concentrations along with ambient temperature and humidity.

Innovair is looking to develop a land mine sensing system with Halo Trust to support demining in Africa. At this stage Innovair are looking to review different technologies to detect different mines (plastic, metal, different structures such as air gaps etc.) from higher distances, as they are aiming to deploy the sensors on drones to cover large unreachable areas.

Ice Rink Energy Project

Ice rinks consume large amounts of energy for lighting, heating, forming ice surfaces, ventilation and operating refrigeration equipment. In addition, they require careful balancing of heating (for user comfort) and cooling (for ideal ice conditions). Inverness Ice Rink have identified a need for more efficient solutions which will be adaptable for the various cooling demands by their users. The ice surface requires low temperature, while the area of the spectators and the athletes need a relatively comfortable temperature. Lighting energy consumption is the third largest energy in the ice arenas. Ice rink refrigeration is a complex system meant to precisely keep temperatures appropriate to the needs of the facility.
The aim of this project is to identify suitable options to find the best and most affordable one for the Ice Centre which will maximise operational savings and provide the flexibility to adapt to user requirements and one which will minimise the effects of a refrigeration breakdown.
Project goals include:
• Developing an innovative energy efficiency solution of the ice rink to minimise the energy consumption since this sector is the largest contributor to energy consumption.
• Developing a more efficient solutions, adaptable for various heating and cooling demands, with a possibility of integrating renewable energy technology and hydrogen battery storage.

Wind Turbine Prototype

Islam, Sheikh (Principal Investigator) Ayub, Ahmad (Co-investigator) Sellami, Nazmi (Co-investigator)

This is £5000.00 Standard Innovation Voucher Award

Four turbine designs (i.e. A, B, C and D) were tested at different wind speed and power produced by the turbines are shown in the report. Turbine D performs better compared to other two turbine designs.
The turbine designs show potential for future application and further testing is required to develop a full scale model. While the effect of environmental condition has not been explored in these experiments, in order to increase the power output of the turbine, a sensitivity on the geometric design parameters needs to also be explored. The effect of major design parameters could be explored using computational fluid dynamics (CFD) and goal driven optimisation techniques. The turbine performance could then be predicted for different altitudes and upstream deflector systems to increase the oncoming wind. An optimised design could also be proposed from the simulation predicted results. A full-scale model could be tested for a long-term operation using a torque sensor, motor and braking assembly. Further CFD modelling and experiments could be carried out to evaluate the potential use this design as a tidal turbine.
