Human Identification with their VOC Distribution Through CMS – SEN Model

Smell printing or odor printing is a novel morphological characteristic that an object can be defined by its odor. Human body odor is one such biological trait that yields less error rate of 15% among other biometrics. The human odor printing or smell printing possesses significance against the world towards screening of security checkpoint, searching for survivals under rubbles, investigating criminals, and many more. Cogno-monitoring system (CMS) is a specific prototype to furnish two essential processes -odor analysis and odor encoding through the Sensing-Encoding-Notifying (SEN) model to give the sensitivity and specificity score among the individuals. Human body odor can be interpreted as the alliance of various volatile organic compounds (VOCs) and they are recognized, classified in the encoding process. This article exhibits a detailed analysis of the traditional detection methods including bioanalysis concerning the human body human body odor experimented with 6 people. By applying principal component analysis along with random forest classifier, the VOCs distribution of the individuals is measured. This work calculates that 18.7% of VOCs are having a match with all the individuals which become the plinth for the identification of humans.

Analysis of Air, Water and Noise Level Quality Due to Industrials Activities in Aceh Province

Air pollution throughout the world, in general, has been at a very alarming rate with the increase in industrial and human activities. In Indonesia, the level of air pollution caused by various industries, especially from motor vehicles, is no longer a secret. Particularly, in the province of Aceh, air, water, and air noise quality in recent years have resulted in deteriorating health for humans and living things. This research analyzed air quality, water odor, and air noise level in the Aceh Province. The results for air quality analysis show an increase in emissions. The noise level of the three regions analyzed is still below the thresholds set. Meanwhile, the results of water odor analysis show its level has exceeded the thresholds set by the Ministry of Environment. Therefore, industrial activities can have an impact on the environment when they are not managed appropriately.

Effects of Olfactory Stimulation on Past and Future Thinking in Alzheimer’s Disease

Several studies have demonstrated that Alzheimer’s disease (AD) is associated not only with difficulty in remembering past events but also with a compromised ability to imagine future ones. Recent empirical research has also demonstrated that odor is an effective cue to alleviate difficulty in remembering past events in AD. We investigated whether odor exposure would help AD patients to imagine future events. To this end, we invited AD patients and control participants to evoke past and future events after odor exposure or without odor. Analysis showed that AD patients and control participants produced more specific and more emotional past and future events after odor exposure than without odor. However, odor exposure did not improve the retrieval time for future thinking in AD participants. This study is the first to demonstrate positive effects of odor exposure on the ability of AD patients to project themselves into the future.
