A SMART AIR POLLUTION MONITORING SYSTEM

Air pollution affects our day to day activities and quality of life. It poses a threat to the ecosystem and the quality of life on the planet. The dire need to monitor air quality is very glaring, owing to increased industrial activities over the past years. People need to know the extent to which their activities affect air quality. This project proposes an air pollution monitoring system. The system was developed using the Arduino microcontroller. The air pollution monitoring system was designed to monitor and analyze air quality in real-time and log data to a remote server, keeping the data updated over the internet. Air quality measurements were taken based on the Parts per Million (PPM) metrics and analyzed using Microsoft Excel. The air quality measurements taken by the designed system was accurate. The result was displayed on the designed hardware’s display interface and could be accessed via the cloud on any smart mobile device

Ambiguity and Nominal Group Multiple Post modification in the Written English of Some Selected Nigerian Polytechnics

Semantic clarity and completeness of idea are two fundamental characteristics of virtually all forms of continuous writing especially essays, letters and reports. However, multiple post-modification of nominal groups often used to achieve clarity and brevity sometimes subjects ideas to ambiguity thereby making them to be susceptible to double or multiple semantic interpretations. This paper presents the outcome of a linguistic study of the continuous writing - essays, letters and reports in the scripts of eighty [80] students of The Federal Polytechnic, Ede, Nigeria offering English courses as compulsory minors. The paper identifies multiple post modification in the usage of the English nominal groups and their tendency to lead to ambiguity. A syntacticsemantic analysis of the ambiguous expressions resulting from multiple post modification is presented detailing the sources of ambiguities that arise. Finally, possible disambiguation methods are suggested especially for English as a second language writers and readers. African Research Review Vol. 2 (1) 2008: pp. 124-15
