MIMO Technology consists of equipping a base station with a large number of antennas to serve many active users. Through MIMO Technology, the ability to concentrate transmitted signal energy in very short spaces would result in huge increases in system capacity. While this new concept provides some fascinating benefits, it creates a new tension that has drawn both academia and industry attention. Channel state information acquisition, channel feedback, instant reciprocity, statistical reciprocity, architecture and hardware impairments are few of them. This paper presents a survey on Spatially Modulated Massive MIMO's historical development.

In this paper, the authors have discussed the fire sensing technologies and what is essential for the discrepancies in the development of hardware and algorithm. The review presents an overview of the existing stateof-the-art practices in the area of fire sensing and control system and it is focused mainly on the excellent capability to detect fire, reduce the detection of false positives, the ability to notify the occupants, passes the information and status of the fires to the fire department, and automatic control capability of the occupants' safety and controlling functions. The major elements of the fire moment like surrounding heat, flame, smoke, and gases level are discussed with their merits, demerits, measurement benchmarks, and measuring the span of the parameters. The reasons and controlling parameters of the fire in commercial and residential buildings are also discussed. Research articles on fire sensing technologies although acknowledged the above concerns. However, importance of robust systems that address all or most of the above-stated benchmarks still remains a challenge and partially addressed. To address the gaps, a modified fire sensing and control system concept has been proposed.

All the relations are found to be identical. The computation has been done on six geological solids and three metals with the help of these relations. All the relations are quite successful in representing the volume and the thermal expansivity as a function of temperature. However, the relation obtained with the help of Tait EOS (Equation of State) is found to be better.

The results so obtained are compared with the available data. The agreement is very good in the whole pressure range of present study. Further, the pressure corresponding to the melting maximum in helium is found to be 17800 kbars.

The model so developed has been applied in 38 liquids. The computed results have been found to be in very good agreement with the experimental data in case of each liquid. The minimum and the maximum ranges of viscosity studied in the present paper are 0.054–0.515cp in CO2 and 16.9–57200.0cp in 2-ethylhexyl-benzoate, respectively. It is interesting to note that the relation is found valid even in the liquid in which the viscosity varies by a factor of 3400, i.e., 2-ethylhexyl-benzoate.
