IN T R O D U C T IO N In recent years there has been a growing concern about the rapidly deteriorating environment in the urban areas of this country in terms of air, water, and noise pollution. Automobile transportation has been found to be a significant factor in the deterioration of the urban environment, particularly in regard to air pollution. In general, con­ sidering the total tonnage of...

Air pollution has received considerable attention by local and global communities (Wald et al, 1999). Many major cities have established air quality monitoring stations but these stations tend to be scarcely distributed and do not provide sufficient tools for mapping atmospheric pollution since air quality is highly variable (Wald et al, 1999). Satellite remote sensing is a valuable tool for as...

air conditioning is widely applied for the improvement of standard of living in human life. this present investigation focused on the prediction of indoor air quality characteristics of air conditioned car using fuzzy logic algorithm. the conditioned space was selected and the experiments were planned as per design of experiments to study the effect of human load, fresh air supply and air veloc...

The review article by Xie and colleagues examines the impact of noise and noise reduction strategies on sleep quality for critically ill patients. Evaluating the impact of noise on sleep quality is challenging, as it must be measured relative to other factors that may be more or less disruptive to patients' sleep. Such factors may be difficult for patients, observers, and polysomnogram interpre...

In this study, results of a variety of ML algorithms are tested against artificially polluted datasets with noise. Two noise models are tested, each of these studied on a range of noise levels from 0 to 50algorithm, a linear regression algorithm, a decision tree, a M5 algorithm, a decision table classifier, a voting interval scheme as well as a hyper pipes classifier. The study is based on an e...

After high-level disinfection of gastrointestinal endoscopes, they are hung to dry in order to prevent residual water droplets impact on patient health. To allow for quick drying and clinical reuse, some endoscopic units use a high pressure air jet (HPAJ) to remove the water droplets on the endoscopes. The purpose of this study was to evaluate the excessive noise exposure with the use of HPAJ i...

BACKGROUND Ototoxic effects of carbon monoxide exposure: a review. AIM To analyze the literature on hearing and Carbon Monoxide (CO). METHODS To describe the physical properties, the absorption, distribution and metabolism of CO, as well as its origin, production, sources and the international standards for occupational exposure. Several studies about the effects of CO exposure to the audit...

This note is concerned with the effects of random noise interference in television transmission systems. Such systems are finding increasing application in surveillance and telefactor systems. Numerous results which have been scattered throughout the literature are collected and unified. Three topics are covered: 1. The calculation of the video signal-to-noise ratio for the commonly used televi...

In this paper, we introduce a cross-layer diversity framework for multi-air interface wireless communication devices. As an initial step, we focus on devices, of the cellular phones type, that have both longrange relatively low-rate communication air-interface (e.g., GSM) and short-range high-rate communication air-interface (e.g., IEEE802.11). The devices can cooperate through the energy-effic...

In most large cities of the developing world, urban air pollution has worsened, which has been detrimental to the health of their populations. At the same time, it is difficult for lay people to sense the level of air quality with bare human perception as air pollutants are mostly invisible and odorless. We believe that computing technologies can help increase awareness of urban air quality. To...
