The Impact of the Two World Wars

Abstract: The First World War seems to have come as a shock to the government of Britain. In spite of the increasingly large public expenditures of the previous three decades on the Royal Navy, and in spite of the emergence of its own military-industrial complex, Britain entered the First World War almost wholly unprepared for it. This sprang largely from the inability of Britain’s military advisers to consider anything but past glories, glories, moreover, of the 18th century rather than the 19th. As French’s (1986) investigations reveal, Liberal military policies in 1914 reiterated those of the 18th century in giving primacy to the role of the Navy to keep the seas open, and to financial and banking support of continental allies whose armies would do the main land-fighting. Britain went into the war with a Navy confident of a short, sharp and successful engagement with the German fleet, and a small professional army not expecting to be called out but grooming their horses just in case. In the event, the German fleet proved equal to the British, the Army had to be massively expanded via conscription and Britain’s ability to fund and manage the finances of its allies collapsed only marginally less quickly than did theirs.

Information technology: catalyst for change in history teaching in schools

Abstract: Databases are commonly used in schools in the U.K. in teaching history. The computer can enable new sources to be introduced to pupils and encourage them to develop skills in statistical analysis. However, the potential exceeds the practice since many history teachers are untrained in statistical techniques. Discussion of the use of a particular data base package. Pride's Purge, suggests ways in which history teachers can be introduced to the techniques of quantitative analysis in order to raise their students' levels of attainment in constructing causal explanations in history. The design and development of the package illustrates an approach to inservice training in both information technology and an academic discipline.

Numerical Modelling of Flood Inundation and Run-Up along the Banks of Pamba River, South West Coast of India

Abstract: The state of Kerala was in the shadow zone of several natural disasters But the disasters which happened during the last two decades changed our perceptions and preconceived notions Before two decades, for Keralites the term disaster was a matter of strange science fiction books, Hollywood cinemas or the things which were happening on the other side of the globe or planet The tsunami of December 26, 2004, Ockhi of 2017, Kerala Floods of 2018 and its replicated version in 2019 exposed our vulnerabilities During the event of 2018 Kerala Floods, the need for a Flood Warning System (FWS) in Kerala was badly felt Though there are many components for a FWS, the main component of a FWS is the prediction of inundation and run-up along the banks of rivers/ water bodies This component can only be accomplished through the process of numerical modelling Numerical modelling is an efficient tool for estimating the past events and predicting the future ones Through numerical modelling different scenarios of possible flood generating permutations and combinations will be carried out and hence in the event of a real time flood warning a closest matching will be picked from these, which will be subsequently used for mitigation The results of numerical modelling will be the base for creating vulnerability maps which will be used for mitigation and rehabilitation This investigation numerically simulates the possible flood rising inundation and run-up along the banks of Pamba River situated on the south west coast of India The model results suggest that extreme rain fall events alone cannot inundate the banks of Pamba River, whereas external discharges emanating from dams, tidal reflections from the oceans etc could inundate the terrain The investigation also recommends several components for successfully establishing a flood warning system in Kerala with specific reference to Kerala floods 2018 How to cite this article: Praveen SS, Babu VS, Vijayan A, Babu SS Numerical Modelling of Flood Inundation and Run-Up along the Banks of Pamba River, South West Coast of India J Adv Res Alt Energ Env Eco 2020; 7(1): 8-14 DOI: https://doiorg/1024321/24553093202002

Wavelength Variation Approach in Single Mode-Multimode-Single Mode Optical Fiber as a Bending Sensor

Abstract: Multimode interference in optical waveguides has interesting self-imaging properties, which have extensively been investigated and utilized in many integrated optical devices. Multimode interference has also been explored in optical fibers in order to realize fiber devices, including sensors. A basic structure of these devices has been the Single mode –Multimode – Single mode (SMS) fiber section concatenation. This dissertation describes theoretical and numerical investigations on multimode interference (MMI) devices using a single mode-multimode-single mode (SMS) fiber structure for possible use as bending sensor using wavelength variation technique. Several aspects of the SMS edge filters have been investigated, including the effect of bending the SMS fiber cores due to fabrication tolerances, polarization dependence, and temperature dependence. These aspects can impair the performance of a wavelength measurement system. There are several approaches which have been proposed and demonstrated to achieve high resolution and accuracy of wavelength measurement. Bending effects due to the splicing process on the spectral characteristics of SMS fiber structure are investigated experimentally with the help of MATLAB. A limit for the tolerable of the cores of an SMS fiber structure based sensor is proposed, beyond which the fiber spectral performance degrades unacceptably. We use Wavelength variation approach by which we can measure the bending more accurately in optical waveguide, as compare to recent sensors. Due to the power loss the power transmission is decreases and efficiency also reduces. So by wavelength variation approach we developed an efficient spectrometer capable of performing a wide variety of coherent multidimensional measurements at optical wavelengths. In this approach we fixed the power and calculate the variation in the wavelength to sense the bending accurately. We apply our algorithm for performing several comparison considerations which shows the performance of our algorithm which is better in comparison to the previous work.

Identification of critical geo-morpho units using GIS - a study in a micro-watershed of Karamana river Basin.

Abstract: The terrain characteristics of an area have an enormous impact on the natural environment as well as socio-economic activities. GIS based terrain models can provide a spatial element with the analysis of variables such as slope, aspect and watershed or catchment area. The present study aims to understand the terrain aspects of a small micro watershed of Karamana river with the perspective of water shed management in the area. This study was carried out using FOSS GIS to understand the basic principles and utility of this tool in identifying critical geo-morpho units in the area. Thus, compound terrain attributes such as L S factor, total curvature, convergence index and Terrain Ruggedness Index (TRI) were computed for the study area. It is hoped that the information provided in this work will be of use in implementing conservation and management strategies for the river systems of Kerala in general and the Karamana river in particular.
