In this paper a review of different semiconductor-type gas sensors is
presented. The different types of gas sensors from various companies
like Hanwei, Libelium, Sandbox Electronics and Sensor Tech SGX are
discussed along with their technical specifications. Environment is
surrounded by various sorts of gases cum pollutants and it is utmost
necessary to keep a efficient check on them as these gases can cause
trouble to the health of human beings and pollute environment
drastically. The main objective of this research paper is to present all
sorts of gas sensors which are based on semiconductors and to generate
awareness regarding which sensor is best for which detection. However,
for more improved sensitivity and selectivity for these sensors, future
trends and outlook for researchers is also suggested. The paper can also
act as base for researchers to get hold of these sensors to develop a
market ready product like drone or robot for Environmental Gas

In the article, a new algorithm for finding coefficients that determine
significance extent of the values of geometric characteristics that are
used for determination of racial and ethnic identity of human is
proposed. It is explained that the calculation of coefficients which
determine the importance extent of the values of geometric
characteristics is important in several respects. The determination of
coefficients that indicate the importance extent of geometric
characteristics causes reduction in numbers of values of geometric
characteristics that don’t have particular importance and in time that
is spent for the identification and improvement of identification
