Design & development of a simulation system for ballistic missile
The computation of the positioning and launching parameters wrt time, for missile system is done by the interface unit called Intercept missile unit (IMU) controlled by computer. When the trajectory is simulated using six degree of freedom to estimate the velocity and location at any instant, this simulation helps in estimation of position coordinates (x, y, z) & angular rotations φ, θ, ø w.r.t time. Aim of this paper is to calculate accurate parameters in computation of trajectory estimation. This proposed algorithm is applicable for Pre-selected range technique. The computed parameters help in deciding kinetic energy to missile for correct hit to target. The proposed simulation were implemented with the experimented data generated for missile having approximate 5 ft diameter with initial power 900ft/s. Apart of this a comparative analysis of proposed simulation with already existing simulations is shown in Table I. Actual developed GUI is shown Fig. 3, which give a clear idea about the merit of this approach. So, this investigation helps to determine the trajectory arcs for missile to hit target accurately.

Dawn or dusk of the 5th age of research in educational technology? A literature review on (e-)leadership for technology-enhanced learning in higher education (2013-2017)
The aim of this article is to establish the extent to which the concept of e-leadership has taken off as a lens through which to study leadership for technology-enhanced learning (TEL) in higher education. Building on a previous study conducted in 2013, this article thus covers an exploratory review of the literature for the period 2103-2017. It analyses 49 articles which explore both the specific concept of e-leadership as well as other work dealing more generally with leadership and organisational change for TEL in higher education. The findings show that while none of the empirical studies identified in the literature refer explicitly to e-leadership, there are a number of interesting insights to be found in the theoretical articles. The results also highlight the widely different interpretations and applications of the concept of e-leadership and the consequent need for the definition to be refined. The paper concludes with recommendations for further multidisciplinary research at the intersection of the fields of educational technology and educational management, focusing on values, strategy, organisation and leadership interactions at meso level, the economy and public policy at macro level, and teaching and learning at the micro level, as well as for research in Leadership Development for TEL.
