Agricultural productivity is something on which economy highly depends. This the one of reasons that disease detection in plants plays an important role agriculture field, as having are quite natural. If proper care not taken this area then it causes serious effects and due to respective product quality, quantity or affected. For instance a named little leaf hazardous found pine trees United States. Detection plant through some automatic technique beneficial reduces large work monitoring big...
This paper gives an overview of the BlueGene/L Supercomputer. is a jointly funded research partnership between IBM and Lawrence Livermore National Laboratory as part United States Department Energy ASCI Advanced Architecture Research Program. Application performance scaling studies have recently been initiated with partners at number academic government institutions, including San Diego Supercomputer Center California Institute Technology. massively parallel system 65,536 nodes based on new...
Power consumption on mobile phones is a painful obstacle towards adoption of continuous sensing driven applications, e.g., continuously inferring individual's locomotive activities (such as 'sit', 'stand' or 'walk') using the embedded accelerometer sensor. To reduce energy overhead such activity sensing, we first investigate how choice sampling frequency & classification features affects, separately for each activity, "energy overhead" vs. "classification accuracy" tradeoff. We find that...

Current algorithms for minimum-energy routing in wireless networks typically select minimum-cost multi-hop paths. In scenarios where the transmission power is fixed, each link has same cost and minimum-hop path selected. situations can be varied with distance of link, higher longer hops; energy-aware a large number small-distance hops. this paper, we argue that such formulation based solely on energy spent single misleading --- proper metric should include total (including expended any...
We propose MRPC, a new power-aware routing algorithm for energy-efficient that increases the operational lifetime of multi-hop wireless networks. In contrast to conventional algorithms, MRPC identifies capacity node not just by its residual battery energy, but also expected energy spent in reliably forwarding packet over specific link. Such formulation better captures scenarios where link transmission costs depend on physical distances between nodes and error rates. Using max-min...
We propose BreathPrint, a new behavioural biometric signature based on audio features derived from an individual's commonplace breathing gestures. Specifically, BreathPrint uses the signatures associated with three individual gestures: sniff, normal, and deep breathing, which are sufficiently different across individuals. Using these gestures, we develop processing pipeline that identifies users via microphone sensor smartphones wearable devices. In user performs gestures while holding...
We investigate the problem of making human activity recognition (AR) scalable-i.e., allowing AR classifiers trained in one context to be readily adapted a different contextual domain. This is important because technologies can achieve high accuracy if are for specific individual or device, but show significant degradation when same classifier applied context-e.g., device located at on-body position. To allow such adaptation without requiring onerous step collecting large volumes labeled...
The inclusion of the barometer sensor in smartphones signaled an opportunity for aiding indoor localization efforts. In this paper, we therefore investigate a possible use detecting vertically oriented activities. We start by showing accuracies various commodity measurement devices and challenges they bring forth. then show how to values build predictor that can detect floor changes mode (elevator, escalator, or stairs) used change floors with nearly 100% accuracy. validate these properties...
This article first surveys existing protocols for supporting IP mobility and then proposes an extension to the mobile architecture, called TeleMIP. Our architecture attempts achieve smaller handoff latency by localizing scope of most location update messages within administrative domain or a geographical region. TeleMIP is intended use in evolving third-generation wireless networks, introduces new logical entity, agent, which provides node with stable point attachment foreign network. While...

Intercropping soybean ( Glycine max L.) with sorghum Sorghum bicolor is common in the semiarid tropics of India. In most intercropping studies, little attention has been paid to belowground interaction and nutrient management other than N while assessing yield advantage. a 5‐yr field experiment (2000–2004), we evaluated impact fertilizer organic manures on below‐ aboveground interaction, competitive ability, economic viability this at Indian Institute Soil Science, Bhopal for deep Vertisol...
We address the problem of energy-efficient reliable wireless communication in presence unreliable or lossy link layers multi-hop networks. Prior work [1] has provided an optimal energy efficient solution to this for case where implement perfect reliability. However, a more common scenario --- layer that is not perfectly reliable, was left as open problem. In paper we first present two centralized algorithms, BAMER and GAMER, optimally solve minimum links. Subsequently distributed algorithm,...

This paper presents the initial design and performance study of MACA-P, a RTS/CTS based MAC protocol that enables simultaneous transmissions in multihop ad-hoc wireless networks. Providing such low-cost high access networks is an important enabler pervasive computing. MACA-P set enhancements to 802.11 DCF allows parallel many situations when two neighboring nodes are either both receivers or transmitters, but receiver transmitter not neighbors. Like 802.11, contains contention-based...
We explore the use of gesture recognition on a wrist-worn smartwatch as an enabler automated eating activity (and diet monitoring) system. show, using small-scale user studies, how it is possible to accelerometer and gyroscope data from accurately separate episodes similar non-eating activities, additionally identify mode (i.e., spoon, bare hands or chopsticks). Additionally, we investigate likelihood automatically triggering smartwatch's camera capture clear images food being consumed, for...
