Meat color recognition using machine vision
New technologies are being developed to give an ease to the human in a variety
of different field each and every day. Food industry is the key of development that led
to the rise of human civilization. The development of food industry dealt with the
husbandry of domesticated animal and plants creating food surpluses that enabled the
development of more densely populated and stratified societies. The study of food is
very important that improves the quality of human's life. When it comes to classify and
grade a meat, the color of fresh meat is a sensory indicator of which affects the
consumers behavior, especially the consistency of meat color and musculature. Other
factors that influence consumers purchasing include security, nutrition and taste. There
has been no report that grades the meat freshness in the process of meat delivery. Most
of the meat freshness is grading manually by using the human eyesight at the meat's
color and quantity of fats. A parameter to show the freshness of meat has only been
analyzed manually using a human's eyes. This is some kind of difficult method when
making a right decision whether the meat is fresh or not. In order to overcome this
problem, meat grading method has been studied to show the mathematical calculation
on the change of color hue, saturation, and intensity (HSI) values. This study focuses on
grading system design that helps to characterize the meat freshness according to its
color. Using a MATLAB Graphical User Interface (GUI) program, it can analyzes the
color of the meat that being inspected. The theory of this program includes the
calculation of the mean values and histograms, and the final result. This system is
capable of classifying meat freshness
NASTRAN structural model for the large 64-meter antenna pedestal. Part 2: Improved model
Static analysis and a computer structural model for the large 64-m antenna pedestal are developed using the MSC version of the NASTRAN program. This improved pedestal model includes the launch areas and the actual pressure pattern of the oil under the hydrostatic bearing pad. The results obtained from the new improved model have indicated that the deflections due to pad loads are in good agreement with field measurements. The top surface deflection of the pedestal obtained from the NASTRAN model is used as an input to the oil film computer program to determine the minimum oil film thickness under the pad
Nonlinear, relativistic Langmuir waves in astrophysical magnetospheres
Large amplitude, electrostatic plasma waves are relevant to physical processes occurring in the astrophysical magnetospheres wherein charged particles are accelerated to relativistic energies by strong waves emitted by pulsars, quasars, or radio galaxies. The nonlinear, relativistic theory of traveling Langmuir waves in a cold plasma is reviewed. The cases of streaming electron plasma, electronic plasma, and two-streams are discussed
Buckling analysis of the quadripod structure for the NASA 70-meter antenna
As part of the effort to extend the diameter of three Deep Space Network large earth antennas from 64 meters to 70 meters, a slim profiled quadripod structure was designed to support a 7.7 meter diameter subreflector for the 70 meter antenna. The new quadripod design, which particularly emphasizes reduced radio frequency blockage, is achieved by means of a narrow cross sectional profile of the legs. Buckling analysis, using NASTRAN, was conducted in this study to verify the safety margin for the quadripod structural stability
Same-sign single dilepton productions at the LHC
We examine the same-sign single dilepton productions of
in high-energy proton-proton
collisions at the Large Hadron Collider (LHC) in models with doubly charged
Higgs scalars as well as heavy Majorana neutrinos. We demonstrate that these
spectacular productions can be detected at the LHC for a class model in which
the doubly charged Higgs scalars couple only to the right-handed charged
leptons. The ranges of the possible doubly charged Higgs masses and mixings to
observe the processes at the LHC are discussed.Comment: 10 pages, 5 figure
HII Regions, Embedded Protostars, and Starless Cores in Sharpless 2-157
We present arcsecond resolution 1.4mm observations of the high mass star
forming region, Sharpless 2-157, that reveal the cool dust associated with the
first stages of star formation. These data are compared with archival images at
optical, infrared, and radio wavelengths, and complemented with new arcsecond
resolution mid-infrared data. We identify a dusty young HII region, numerous
infrared sources within the cluster envelope, and four starless condensations.
Three of the cores lie in a line to the south of the cluster peak, but the most
massive one is right at the center and associated with a jumble of bright radio
and infrared sources. This presents an interesting juxtaposition of high and
low mass star formation within the same cluster which we compare with similar
observations of other high mass star forming regions and discuss in the context
of cluster formation theory.Comment: accepted to ApJ; 6 pages, 3 figure
