Tech startups are integral drivers of economic growth in any economy, given their potential role and significance in employment generation, wealth creation, and aggregate output of a nation. However, most startups are ... -
Financing Strategies of Tech Startups in India: Determinants, Value, and Impact of VC Involvement
In recent years, the increased emphasis on digitalisation aided by advancements in technology has led to the growth of digital startups in India. Compared to non-digital startups, digital startups are those that focus on ... -
Finding A Subset Of Non-defective Items From A Large Population : Fundamental Limits And Efficient Algorithms
(2017-07-12)Consider a large population containing a small number of defective items. A commonly encountered goal is to identify the defective items, for example, to isolate them. In the classical non-adaptive group testing (NAGT) ... -
Finding the Way Back Home : A study of Spatial Orientation, Navigation and Homing Behaviour in the Social Wasp Ropalidia marginata
(2018-05-23)For most of the animals, if not all, finding their way to a particular place is crucial for survival. To address this challenge of way-finding, different animals have evolved with different homing strategies. Social ... -
