Abstract- This paper deals with the Wavestar WEC with different buoy geometry. Two spherical and conical geometries are compared in single numbers as well as linear and circular arrays. The boundary element method and radiation/diffraction theory have been used to study the power performance of the Wavestar wave energy converter. For validation of numerical simulation in ANSYS/AQWA, the heave position and velocity for with and without case study compare with experimental data. Single Wavestar with spherical and conical geometry under different wave periods investigated and then two linear and circular arrays for both considering geometries compared with each other. The result shows that the maximum power of the conical geometry has higher than that of the spherical geometry for a single WEC at a wave period of 7s. A similar result was found on the Wavestar array. In addition, it found that with increasing incident wave period, the difference between the absorbed powers decreases, while in shorter wave periods, there is a significant difference.

Keywords- Wave Energy Converter, Wavestar, Spherical, Conical, Linear and Circular Array and Power Production.

Abstract- Wheels Intelligent wheelchair systems implemented for patient monitoring are mobile aids for people with special abilities, while constantly monitoring the essential physical parameters of the user. To accommodate different disabilities, four wheelchair control interfaces have been developed, namely eye detection control, gesture capturing control, joystick-based control and voice recognition control. The camera is used to take pictures of the eyeballs. The remaining three modes also provide wheelchair motion control. Ultrasonic sensors are used to implement anti-collision mechanisms. In a wheelchair, monitoring of temperature and heart rate is provided. If any parameter is outside safe limits, the system alert with the appropriate medical facility and selected personnel of the wheelchair user. The final project is a support technology like no other that makes the user's life easier and more relaxed.

IoT Based Pollution Detection System

Shaheer Bin Ijaz, Ayesha Khan

University of Engineering and Technology, Lahore

Abstract- An application is developed which addresses this problem by visualizing the collected air pollution data. It generates graphs which show different intensities of particulate matter at different locations. Some other features like giving necessary precautions suggested by W.H.O according to the current AQI Level which provides a good user experience with the application. Other main features include data visualization, future AQI prediction. At every data point date and time is specified which shows that on which date and at what time data is gathered. The device collects data and pre-process it in real-time and sends it to the cloud storage and then that data is being fetched by the apps and being displayed using graphs. A model is trained on the collected data to give future prediction and forecasting. Moreover, necessary health precautions according to the current AQI, suggested by W.H.O are also provided.

Keywords- Pollution Detection System, IoT-Based, Forecasting, Solutions and Locations

Abstract- METAVERSE, it’s a technology that will change the coming internet of things. Evolutions of virtual worlds where the user can meet up, shop, invest, play games and many more. This technology is the merger of many technologies like artificial intelligence, virtual reality, augmented reality Extended reality XR and global chain of internet which will be governed by the block chain. Against every transaction the NFTs (Non-Fungible Tokens) will be created for the specific user. By owning a wallet with access to your private keys, you can instantly prove ownership of activity or an asset on the block chain. Here the major elaboration of these technologies merger how they will interact with each other to make a proper virtual environment.
