An Efficient top- k Query Processing in Distributed Wireless Sensor NetworksIJMER
Wireless Sensor Networks (WSNs) are usually defined as large-scale, ad-hoc, multi-hop and
wireless unpartitioned networks of homogeneous, small, static nodes deployed in an area of interest.
Applications of sensor networks include monitoring volcano activity, building structures or natural
habitat monitoring. In this paper, we present the problem of processing probabilistic top-k queries in a
distributed wireless sensor networks. The basic problem in top-k query processing is that, a single method
cannot be used as a solution to the problem of top-k query processing because there are many types of
top-k query processing. The method has to be based on the situation, the classification and the type of
database and the query model. Here we develop three algorithms, namely, sufficient set-based (SSB),
necessary set-based (NSB), and boundary-based (BB), for inter- cluster query processing with bounded
rounds of communications. Moreover, in responding to dynamic changes of data distribution in the
overall network, we develop an adaptive algorithm that dynamically switches among the three proposed
algorithms to minimize the transmission cost.
This document summarizes an analysis of future energy scenarios for Ireland. It finds that transport and residential sectors currently demand the most energy. Business as usual would rely heavily on imported fossil fuels, posing security risks. Demand side management could reduce energy demand by 10% by 2040 through peak load management and efficiency improvements. The 202020+offshore scenario, involving renewable energy targets for 2020 and 2030, efficiency measures, and offshore wind and ocean energy, could reduce emissions 25% below business as usual levels by 2040. Key strategies include renewable feed-in tariffs, electric vehicles, biofuels, public sector efficiency targets, and offshore renewable development.

This document presents a new method for determining the true value of pi (π) based on the relationship between a square and its inscribed circle. The method involves calculating the areas of the square and circle, then the remaining corner area. Any π value used will resurrect in the decimal portion of the final calculation. Only one value - 3.14644660942 (derived from 14/4-2) - results in all decimals resurrecting accurately. Therefore, this "natural selection" method concludes this value is the true π.
The document provides photography tips including taking shots from different angles including eye level, shooting down, and shooting up.

This document discusses using electrical resistivity measurements to evaluate properties of expansive soils containing bentonite. Laboratory experiments were conducted mixing bentonite into clayey soil at ratios from 10-100% to produce samples with varying swelling potential. Field electrical resistivity measurements were taken using a four-electrode probe on the soil samples. Linear correlations were determined between electrical resistivity and various soil properties including liquid limit, plastic limit, shrinkage limit, swelling pressure, and maximum dry density at different bentonite ratios. The correlations allow direct estimation of soil properties from electrical resistivity measurements in the field without laboratory testing.

1) An analytical formulation to model the free vibration of sandwich beams with single or multiple delaminations, representing the beam as segmented Euler beams joined at delamination boundaries.
2) Experimental validation showing delaminations reduce natural frequency and change mode shapes compared to intact beams.
3) Finite element analysis in ANSYS correlating with experiments.
4) Use of strain plots to identify delamination location and extent, improving on prior methods. The formulation is extended to multiple delaminations, providing insights into their complex effects on sandwich composite behavior.

This document summarizes a research paper that proposes a novel reversible data hiding scheme using AES encryption. The scheme consists of three phases: 1) AES encryption of the original image, 2) data embedding by modifying parts of the encrypted image, 3) data extraction and image recovery by decrypting the encrypted image and extracting the hidden data. The scheme aims to securely hide data in images while allowing perfect recovery of the original image. Experimental results show the decrypted image has a high PSNR value of 55.11dB and the hidden data can be successfully extracted.

Methodology used for improving overall equipment effectiveness by Implementi...IJMER
The global marketplace is highly competitive and organizations who want to survive long-term, have to continuously improve, change and adapt in response to market demands. Improvements in
a company's performance should focus on cost cutting, increasing productivity levels, quality and
guaranteeing deliveries in order to satisfy customers. Total Productive Maintenance (TPM) is one
method, which can be used to achieve these goals. TPM is an approach to equipment management that
involves employees from both production and maintenance departments. Its purpose is to eliminate major
production losses by introducing a program of continuous and systematic improvements to production
equipment.

This document presents an experimental study on the parameters affecting the tribological performance of nano lubricant containing multi-walled carbon nanotubes (MWCNT) using design of experiments (DOE). Four factors were studied - MWCNT quantity, surfactant quantity, load, and speed. Experiments were conducted using a block and disk test setup to measure wear. The results showed that speed and MWCNT quantity had the greatest effect on wear, followed by surfactant quantity and load. The interaction between load and surfactant quantity and between load and MWCNT quantity were also significant. The study concluded that adding 0.05% MWCNT to the nano lubricant significantly reduced wear under different load and speed conditions

Position Determination of an Aircraft Using Acoustics Signal ProcessingIJMER
This paper deals with the determination of an aircraft position using the acoustic source
emitted from it. As per the experimental setup, sound energy emitted from the aircraft is captured with
the help of microphones and processed further using MATLAB toolbox and LABVIEW software.
Localization algorithm is sub divided into two categories, in which the first method involves time delay
estimation of acoustic source through simulation process and the second method is analyzing the
Doppler frequency shift from the aircraft sound. Using the above methods the navigation parameters
such as velocity, Height, Mach number, RPM of the propeller, Elevation angle and slant range will be
determined.
A Review of FDM Based Parts to Act as Rapid ToolingIJMER
Abstract: Fused Deposition Modeling (FDM) is one from basic Rapid Prototyping (RP) technologies
used in technical practice. In this contribution are presented basic information about parameters such
as layer thickness, part build orientation, raster angle, raster width and air gap. This study provides
insight into complex dependency of strength on process parameters. In this paper microphotographs
are used to show the mechanism of failure. The major reason for weak strength is attributed to
distortion within or between the layers.Developing a curved layer deposition methodology can
improve part quality by reduced lamination, reduction in the staircase effect which leads to improved
dimensional accuracy of the part. Less effort has been made to increase the range of FDM materials
to include metals or metal based composites with the help of metal based composite direct rapid
tooling will allow fabrication of injection moulding dies and inserts with desired thermal and
mechanical properties suitable for using directly in injection moulding machines for short term or
long term production runs.
