Problem Definition

Problem 1:

With the development of next generation wireless communication system, development in personal computing devices and wide use of mobile and other hand handheld devices are increasing with multimedia technology, thereby increasing the population of MANET. Tasks maintaining the good performance of these networks present a number of technical obstacles.

Some of the obstacle which needs to be taken care of to accomplish acceptable performance benchmarks are as follows:

  • An efficient task scheduling with load balancing
  • Bandwidth estimation
  • Efficient power management
  • Maintenance of non functional parameters

 Problem 2:

The cloud aims to offer distributed, virtualized and elastic resource as utilized by the end users. The power of virtualization enables the enterprises to lease computing power in the form of virtual machines to the user.

Broadly we can categorize the issues in three parts:

Issue 1: “Shooting through the roof”- power consumption.

Issue 2: Quality of Service (QoS) as per user expectation.

Issue 3: Load balancing and dynamic resource allocation in the nodes

It is indeed challenging to address the above mentioned problems while maintaining acceptable levels of QoS. The power of Virtualization has proven useful for on-demand service provisioning and addressing the challenges of utility as of computing and elasticity nature.

Problem 3:  Machine Learning Approach to understanding Astrophysical Data: The Final Frontier:: Novel algorithmic study.

The problem of Supernova classification (identifying the type of supernova from their spectra, ex type 1a, type 1b, type 2, etc.), and are interested in applying machine learning techniques to solve this problem. Briefly, the main challenge of this problem is the fact that the supernova itself change over time. That is, it can belong to different type depending on when it is observed.  Another challenge of this problem is that we have a small dataset, usually in the order of hundred. Supernovae are important in cosmology because maximum intensities of their explosions could be used as “standard candles”. Briefly, it helps astronomers indicate the astronomical distances.

The problem is pivoted around two major challenges in data estimation and analysis.

→ Parameter estimation using complex models

→ Data analysis of noisy, nonstandard data types.

Problem 4:Life Information Score: Exploring the probability of Life and its complexities in Exoplanets :: A Novel Computing Model

An extrasolar planet, or exoplanet, is basically a planet outside the Solar System. As far as it is understood, an ultimate goal is to discover the Earth 2.0, those extrasolar planets that orbit in the habitable zone where it is possible liquid water to exist on the surface. The detection of exoplanets itself is very difficult, let alone the extraction of molecular composition of the planets, because planets are extremely faint compared to their parent stars. The problem opens up many questions which are not only related to Physics but Computing, among other fields!
