A Novel Method to Eliminate the Symmetry Dependence of Fiber Coils for Shupe Mitigation
It is a well-known fact that interferometric fiber optic gyroscopes (IFOGs)
are easily distorted by thermal effects and distortion results in the
degradation of the performance of these sensors. Changing the fiber coil
geometry, increasing the winding symmetry, adding fiber buffer layers around
the fiber coil, using different modulation methods for multifunctional
integrated optic chips (MIOCs), and using special types of fibers, such as
photonic crystal fibers (PCFs), are some alternative solutions for preventing
this degradation. This paper, theoretically and experimentally, investigates
not only how different types of fiber coil winding methods behave under
different rates of temperature change but also presents a novel method, to the
best of our knowledge, to eliminate the Shupe effect, without violating the
simplest IFOG scheme. This method rules out the importance of the winding
symmetry epochally and the need of any extra treatment for the fiber coil to
increase the thermal performance of the system. Regardless of the symmetry of
the fiber coil winding, the rate error due to the Shupe effect can be reduced
to about h for any rate of temperature change with this new
method according to the experimental results.Comment: Manuscript: 8 pages, 5 figures. Supplementary: 10 pages, 6 figure
Sexual life of women in the climacterium: A community-based study
Our purpose of conducting this community-based study was to determine sexual functions of women in climacterium and effects of menopausal symptoms on sexual functions. It was descriptive, cross-sectional, and community-based. The study sample consisted of 282 climacteric women. Menopause Rating Scale (MRS), Female Sexual Function Index (FSFI), and Sexual Satisfaction Scale for Women (SSS-W) were used for data collection. The total score was 13.42 +/- 8.82 for MRS, 18.73 +/- 9.79 for FSFI, and 82.56 +/- 18.07 for SSS-W. Seventy-nine-point four percent of the women had sexual dysfunction. While complaints typical of the climacteric period increased, sexual functions and satisfaction decreased
