Numerical Investigation of Missile Strike over an Unmanned Aerial Vehicle
Abstract: Objectives: The present work deals with the impact analysis of missile over an unmanned aerial vehicle (UAV), the missile is made to strike on the UAV with various angles on the different locations and structural behaviour of the UAV will be investigated through the intended work. Novelty: There is very limited data concerning structural failure modes caused by impact and explosion loading on an UAV due to missiles. Method: The …

Radon Studies for Uranium Exploration, Environment Health Hazards and Earthquake Prediction
Abstract: During 1975, when my research laboratory in Geochronology became operational in Punjabi University, Patiala, I came in contact with Robert McCorkell, a geologist of Carleton University in Ottawa, Canada. He helped me a lot in sending literature concerning my research in inter-disciplinary areas of my choice. He suggested that using simple instrumentation, one can start some research activity in Radon monitoring in soil and groundwater. On the basis of his …

Historical Review of Ionosphere in Perspective of Sources of Ionization and Radio Waves Propagation
Abstract: Before the discovery of ionosphere, the electronic communication was not possible at a distance greater than 100 km due to the curvature of Earth; but after its discovery, the ionospheric wave propagation made possible the electronic communication at even more than 3000 km via reflection of radio waves through ionosphere. The ionosphere is electrically neutral, ranging from 50 to 1000 km in altitude and outer limit can exceed to 3000 …

Heavy Ion Radiation Damage Track Studies in SSNTDs (Polymers, Glasses and Minerals) and Single Activation Energy Model
Abstract: My training in Marie and Pierre Curie University, Paris for the identification of relativistic particle tracks in nuclear emulsions came handy for shifting to Heavy ion track studies in solid state nuclear track detectors (SSNTDs). Track formation mechanism in both may be different, but the basic nature of phenomenon by which the tracks are produced remains essentially the same. All charged particles produce ionisation of the medium and lose energy …

Modelling of Flood in Lagos using Artificial Neural Network
Abstract: Flooding events have caused havoc to live and properties in recent times. Flooding could be caused by several factors some of which are rainfall, temperature, and relative humidity, which lead to rise in water level. The method of artificial neural networks (ANN) was used in this work to model flood occurrence in Lagos, Nigeria. Meteorological data were collected from the Nigeria Meteorological Agency (NIMET) and Nigeria Hydrological survey Agency (NHSA) …

The Study of Temporal Variations in Ionosonde foF2 and GPS TEC at Multan and Islamabad during Low and High Solar Activity in Solar Cycle 24
Abstract: The study of temporal variations in critical frequency of the F2 layer (foF2) and total electron content (TEC) calculated from satellites of GPS (Global Positioning System) has been conducted at Multan (Geog. Lat: 30.16°N, long: 71.53°E) and Islamabad (33.66°N, 73.23°E) during low solar activity (LSA) year 2009 and relatively high solar activity (HSA) year 2012 of solar cycle (SC) 24. In general, it has been observed that the diurnal variations …
