Non-Linear Spectral Unmixing Of Moon Mineralogy Mapper (M3 ) Data, Keshav Dev Singh, Ramakrishnan Desikan
Innovative Research Publications IRP India
Most of the approaches to solve the unmixing problem are based on the Linear Mixing Model (LMM) which is questionable. Therefore, nonlinear spectral model is generally used to study the effects of multiple scattering in the complex surfaces. In this paper, we have demonstrated the application of Radiative Transform Equation (RTE) based Hapke multi scattering model. The Hapke model based non-linear spectral unmixing is carried out on a Moon Mineralogy Mapper (M3 ) data. The values of six non-linear Hapke's model parameters are estimated using a MATLAB based algorithm after optimizing the Hapke corrected M3-Endmembers and modeled spectra through minimum …

Energy Aware Forwarding In Content Centric Based Multihop Wireless Ad Hoc Networks, Rana Asif Rehman, Byung-Seo Kim
Energy Aware Forwarding In Content Centric Based Multihop Wireless Ad Hoc Networks, Rana Asif Rehman, Byung-Seo Kim
Rana Asif Rehman
Content centric networking (CCN) is a newly proposed futuristic Internet paradigm in which communication depends on the decoupling of content names from their locations. In CCN-based multihop wireless ad hoc networks, the participating nodes show dynamic topology, intermittent connectivity, channels fluctuation, and severe constraints such as limited battery power. In the case of traffic congestion, the affected nodes die early owing to the shortage of battery power. Consequently, all pending request entries are also destroyed, which further degrades the network performance as well as the node working lifetime. In this study, we have proposed a novel energy aware transmission scheme …

Electronics Elements
We know trash is an enormous problem in the world since trash does not only affect just humans but it also affects living creatures in general. The biggest contributor of trash in the United States is food waste. Food waste is produced by every human and the amounts of food waste is astonishing. Americans throw away almost half of the food that they buy, which is almost worth $165 billion per year. Food waste which end up in landfills and incinerators produces methane which is a greenhouse gas and can contribute to global warming. Trash in general and food waste …

An Intelligent Attitude Determination And Control System Concept For A Cubesat Class Spacecraft, Jeremy Straub
Jeremy Straub
An attitude determination and control system (ADCS) is used to orient a spacecraft for a wide variety of purposes (e.g., to keep a camera facing Earth or orient the spacecraft for propulsion system use). The proposed intelligent ADCS has several key features: first, it can be used in multiple modes, spanning from passive stabilization of two axes and unconstrained spin on a third to three-axis full active stabilization. It also includes electromagnetic components to ‘dump’ spin from the reaction wheels.

Not Just A Tool. Taking Context Into Account In The Development Of A Mobile App For Rural Water Supply In Tanzania, Robert Hoppe, Anne Wesselink, Rob Lemmens
Robert Hoppe
The 'eGovernance' hype around the potential of mobile phone and geoweb technologies for enhancing 'good governance' is soaring. In East Africa, the extensive use of mobile telephony adds to the imagined promises of ICT. We reflect on the assumptions made by the proponents of such tools, using our own action research project as an example. We took great care to consider context in the development of software for enhancing empowerment and accountability in rural water supply in Tanzania. However, we found that the rural water supply context in Tanzania is much more complex than the contexts for which successful mApps …

Ndn-Crahns: Named Data Networking For Cognitive Radio Ad Hoc Networks, Rana Asif Rehman, Jong Kim, Byung-Seo Kim
Rana Asif Rehman
Named data networking (NDN) is a newly proposed paradigm for future Internet, in which communication among nodes is based on data names, decoupling from their locations. In dynamic and self-organized cognitive radio ad hoc networks (CRAHNs), it is difficult to maintain end-to-end connectivity between ad hoc nodes especially in the presence of licensed users and intermittent wireless channels. Moreover, IP-based CRAHNs have several issues like scalability, inefficient-mapping, poor resource utilization, and location dependence. By leveraging the advantages of NDN, in this paper, we propose a new cross layer fine-grained architecture called named data networking for cognitive radio ad hoc networks …

A Software Defined Radio Communications System For A Small Spacecraft, Michael Hlas, Jeremy Straub, Ronald Marsh
Jeremy Straub
Software defined radios (SDRs) are poised to significantly enhance the future of small spacecraft communications. They allow signal processing to be performed on a computer by software rather than requiring dedicated hardware. The OpenOrbiter SDR (discussed in [1] and refined in [2]) takes data from the flight computer and converts it into an analog signal that is transmitted via the spacecraft antenna. Because the signal processing is done in software, the radio can be easily reconfigured. This process is done in reverse for incoming transmissions, which are received by the SDR and decoded by software. Figures 1 and 2 provide …
