The Future of Artillery in 21st Century Warfare

The article visualises the future of Artillery in the 21st century. It brings out the requirement of Artillery in the nine conflicts till datein the 21st Century. It is observed that Artillery is required to perform three primary tasks: First, Surveillance and Target Acquisition; second, engagement of targets; and third, post-strike damage assessment. The future battlespace would be non-linear with the need for simultaneous engagement in the close, intermediate, and depth areas. Based on these aspects, one arrives at the future profile of Artillery and the equipment needed for the task. This results in the type of regiments and their equipment in the Indian context. The Surveillance and Target Acquisition (SATA) Regiments, Gun Regiments, Mortar Regiments, Rocket Regiments, and BrahMos supersonic Cruise Missile Regiments would compose the future set up of Artillery. In view of this, the paper will discuss, ammunition, the weapon of the Artillery; and the aspects of Precision Guided Munitions, Loitering Munitions as also the Long Range ammunition being developed by BAE System, and Lockheed Martin

Futuristic Technologies and Weapon Systems of the 21st Century

Technology is the application of scientific knowledge for practical purposes that involves development, processing, and management. Technology is dynamic and keeps on improving at a high speed. Currently, we are in the Information Age and a variety of advanced technologies are being used in our day-to-day life. For instance, in communications technology, today the phone can prepare a PowerPoint presentation, construction material are being fabricated on 3D computers, blood can be tested without samples, a guitar can be played using an application and learning can be done by Artificial Intelligence —exemplifying the advancement under the use of technology

Characterization of Landraces of rice following DUS guidelines

For the establishment of the distinctness among fifty one landraces of rice, fortysix characters were used. Characterization of fifty one landraces of rice was done using 46agro-morphological traits following Distinctiveness, Uniformity and Stability test (DUS)during kharif season of 2008 2009 and 2010 at the Zonal Adaptive Research Station,Krishnagar, Nadia, West Bengal. Out of fifty one varieties studied, twenty seven werefound to be distinctive on the basis of twenty two essential and twenty four additionalcharacters. This study will be useful for breeders, researchers and farmers to identify andchoose the restoration and conservation of beneficial genes for crop improvement andalso to seek protection under Protection of Plant Varieties and Farmer’s Rights Act

Some Aspects in the Design of Sonar Domes

The importance of vibro-acoustic characteristics in the design of hitherto conventional Sonar Domes is discussed. A practical method of studying full scale domes for their vibro-acoustic characteristics is suggested

Aspects of Network Harmonic Impedance Modelling in High Voltage Distribution Networks

This paper evaluates the performance of five leading power system analysis softwares in terms of network harmonic impedance calculation for High Voltage distribution grids. Based on a set of systematic case studies the first part of the work presents a comparative analysis of the software packages in calculation of first resonance point. The different network element models and load models and their impact on the resonance parameters are discussed in detail. The second part of the research work assesses the sensitivity of the resonance parameters (impedance magnitude and frequency) depending on the change of certain network model parameters and compares the results amongst the different software packages. This gives an idea about the robustness of frequency and magnitude response at the resonance point and points out the most sensitive parameter in a HV network
