    The paper presents advanced mission management system (MMS) for unmanned aerial vehicles, based on integrated modular avionics (IMA) architecture. IMA architecture enables the MMS to host high end functions for autonomous navigation and attack. MMS is a collection of systems to execute the mission objectives. The system constitutes mission computer (MC), sensors and other sub-systems. The MMS-MC needs to execute advanced algorithms like terrain referenced navigation, vision-aided navigation, automatic target recognition, sensor fusion, online path planning, and tactical planning for autonomy and safety. This demands high-end architecture in terms of hardware, software, and communication. The MMS-MC is designed to exploit the benefits of IMA concepts such as open system architecture, hardware and software architecture catering for portability, technology transparency, scalability, system reconfigurability and fault tolerance. This paper investigates on advanced navigation methods for augmenting INS with terrain-referenced navigation and vision-aided navigation during GPS non-availability. This paper also includes approach to implement these methods and simulation results are provided accordingly, and also discusses in a limited way, the approach for implementing online path planning.Defence Science Journal, Vol. 64, No. 5, September 2014, pp.438-444, DOI:http://dx.doi.org/10.14429/dsj.64.599

    Exclusive breastfeeding (EBF)—giving infants only breast-milk for the first 6 months of life—is a component of optimal breastfeeding practices effective in preventing child morbidity and mortality. EBF practices are known to vary by population and comparable subnational estimates of prevalence and progress across low- and middle-income countries (LMICs) are required for planning policy and interventions. Here we present a geospatial analysis of EBF prevalence estimates from 2000 to 2018 across 94 LMICs mapped to policy-relevant administrative units (for example, districts), quantify subnational inequalities and their changes over time, and estimate probabilities of meeting the World Health Organization’s Global Nutrition Target (WHO GNT) of ≥70% EBF prevalence by 2030. While six LMICs are projected to meet the WHO GNT of ≥70% EBF prevalence at a national scale, only three are predicted to meet the target in all their district-level units by 2030

    Among other sectors the Industrial sector has not been any exception during the pandemic that shook the entire world.In India especially the fourth cadre people of Industries i.e the laborers faced the harsh situations in their life to even survive without employment.Many sectors along with the business sector where Medium and small scale Industries faced a very crucial times during the lock-down that was imposed in India where remarkable changes were seen in almost every employees life.Many of the laborers were compelled to leave the job and migrate to their hometown as there was a layoff in their Enterprises and some were even closed or are on the verge of closure due to no production and money crunch as well.This Research paper encompass those parameters on the bases of which the Small and Medium scale Industries were running short of finance or were temporarily closed. Studies and surveys shows that approximately 95% firms were impacted negatively due to national lockdown imposed in April 2020, 70% of businesses remained disrupted till August 2020. Even after progressive unlocking, reports suggest that almost 40% businesses remained interrupted till the end of February 2021.</jats:p

    In order to distinguish their brand companies are trying to be more strategic and adding innovative features in their product offerings. But in today’s time product differentiation exclusively on basis of product attributes is not going to help companies in long run. Subsequently, marketers are inventing different communication strategies to help brands stand out (La Ferle et al., 2013). Cause related marketing has become a new buzz word in the world of marketing communication techniques. Purpose: The main purpose of this paper is to find impact of Cause Related Marketing (CRM) campaigns on consumer attitude and further the study also provides an analysis of comparative impact of cause related marketing and sales promotion on consumer attitude. Methodology: For the collection of primary data, structured questionnaires were distributed among respondents. A total of 300 respondents were initially contacted, out of which total of 270 responded back. The comparative analysis was done on the basis of Wilcoxon signed rank test. Findings: The result of the study shows that the consumer has more positive attitude towards cause related marketing as compare to the sales promotion strategy. Implications: From the analysis, it is observed that a company can gain more consumer attention if much emphasize can be given in designing cause related marketing strategy, this will provide an opportunity to company to become a socially responsible citizen.</jats:p
