one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
this thesis is going to delineate the concept of the reader as implied in 18th century literary theory; based on the study of the major reader oriented elements of criticism of the age-taste, the sublime, and aesthetic pleasure-its aim is to explain what sott of reader is implied and what kind of response on the part of the reader is proposed in 18th century english literary theory and aestheti...
a specific form of the inertial law is presented by which we can gain a deeper insight into the essence of mass and inertia. in this modified theory, there is no need to keep the concept of absolute space and newton's third law as principles, by introducing a convenient form for gravitational law the coupling constant g becomes a function of inertial parameters of the universe
In this letter, it is shown that dark energy is contributed by riccion (a particle concept for physical aspect of the Ricci scalar curvature) in a natural way without any input in the theory for it. It is in contrast to other models, where an idea for dark energy is introduced in the beginning of the theory. Interestingly, it is found that dark energy density, obtained here, decreases with the ...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
We measured Newton's gravitational constant G using a new torsion balance method. Our technique greatly reduces several sources of uncertainty compared to previous measurements: (1) It is insensitive to anelastic torsion fiber properties; (2) a flat plate pendulum minimizes the sensitivity due to the pendulum density distribution; (3) continuous attractor rotation reduces background noise. We o...
Progress and plans are reported for a program of gravitational physics experiments using cryogenic torsion pendula undergoing large amplitude torsional oscillation. The program includes a UC Irvine project to measure the gravitational constant G and joint UC Irvine– U. Washington projects to test the gravitational inverse square law at a range of about 10 cm and to test the weak equivalence pri...
Multidimensional cosmological models with factorizable geometry and their dimensional reduction to effective four-dimensional theories are analyzed on sensitivity to different scalings. It is shown that a noncorrect gauging of the effective four-dimensional gravitational constant within the dimensional reduction results in a non-correct rescaling of the cosmological constant and the gravexciton...
postcolonial feminism, also dubbed as third world feminism, is an innovative approach, demonstrating the way women of colonized countries suffer from both native patriarchies and imperial ideology. also due to this double-colonization, postcolonial feminists contend that third world women are subjected to both colonial domination of empire and male domination of patriarchy. while western femini...
