Selection of Optimal Threshold in Digital Images using Collision Entropy and Min Entropy
Abstract: AbstractImage segmentation partitions an image into multiple segments based on properties of discontinuity and similarity. Thresholding is one of the important methods for image segmentation. It is used to discriminate foreground from the background of an image. The selection of suitable threshold value in the image is a challenging task. Thresholding value depends upon the randomness of intensity distribution of the image. Entropy is a parameter to measure the randomness …

Composite Gel-Fibers and Solid-State-Processed Tapes Based on Disentangled Ultra-High Molecular Weight Polyethylene and Electrically Conductive Carbon Black: a Comparative Study
Abstract: In this study, oriented nanocomposite gel-spun fibers and solid-state-processed tapes were manufactured and analyzed. The fibers and tapes were produced using a specific type of nascent disentangled ultra-high molecular weight polyethylene (UHMWPE) reactor powder. As the filler, commercially available electrically conductive carbon black (CB) was used. The ultra-high filler content values up to 75 wt.% were achieved for the UHMWPE/CB gel-spun fibers, while the degree of filling was limited (up …

Assessment of Liquefaction Potential Index for Sylhet City considering Maximum and Average Amplification Factor
Abstract: Soil liquefaction often occurs in saturated or partially saturated silty or sandy soil when an earthquake generates dynamic cyclic stress in the soil mass, reducing shear strength and stiffness. This study aims to assess the seismic soil liquefaction hazard potential for Sylhet City using shear wave velocity profiles of 49 boreholes. Factor of Safety (FOS) was evaluated taking into account shear wave velocity and maximum intensity of surface acceleration corresponding …

Removal of Blotches and Impulse Noise in Gray Scale Images Using Non-linear Algorithm
Abstract: An image consists of artifact, which appears in an image that is actually not present in the original imaged object. An image artifact (noise) is sometimes the result of improper operation of the imager, and other times a consequence of natural processes or properties of the human body. Blotches (bulk noise) and impulses are the artifacts where blotch can be either bright or dark spots and impulse can be salt …

ENERGY LOSSES IN FLOATING OFFSHORE WIND TURBINE WITH VARIABLE WIND DIRECTION
Abstract: The paper analyses the effects of the variation of wind direction onto the performance of a floating offshore wind turbine (FOWT). The evolution of the Cp coefficient is developed as a function of the velocity of the yaw angle correction when realigning the FOWT after a wind direction change. The results are computed for velocities correction of the yaw angle between 1º/min and 5º/min. A maximum drop of the Cp …

Building a Resilient Climate Regulatory Ecosystem for Nigeria
Abstract: Terrestrial ecosystems, which store more carbon than the atmosphere, are vital to influencing carbon dioxide-driven climate change. Climate and land-use change are critical and interlinked components of the Carbon budget in human-dominated landscape, using the InVEST model maps of land use and stocks in four Carbon pools (aboveground biomass, belowground biomass, soil, dead organic matter) are used to estimate the amount of Carbon currently stored in the landscape and the …

Liquefaction Behavior of Clean Sand for Various Sample Sizes Using Triaxial Tests
Abstract: A total of 54 isotropically consolidated un-drained triaxial compression tests on various sample sizes were conducted to study the effect of sample size on liquefaction behavior of clean sand. Specimens were prepared using moist placement and dry deposition methods with different initial relative densities and tested for different confining pressures. It was observed that as the sample size increases, deviator stress also increases. Peak value of deviator stress increased as …

Effect of Construction Load on RC Floor Slab
Abstract: In reinforced concrete building structures, floors are added from bottom to top sequentially.The load due to construction of new floor is transferred to the lower floor slab through shoring. Different construction practices are adopted at work sites for the transfer of this load. The effect of construction practices was reviewed. The threshold value for bending moment under construction load is marked to provide the caution against the possible failure of …

Design and Evaluation of Nano-cantilever Beam for Sensing Application
Abstract: Sensor array offers several advantages such as selectivity enhancement towards analytes,multiple component analysis etc. In case of an array system, we see that one cantilever beamcan be set as a reference, while the other beams are subjected to varying loads. As a result,even a very small deflection would be detected with the help of adjacent beams, henceenhancing the sensitivity of the cantilever. By using an array of beams with differentfunctionalization …
