We review the recently published results from the CBI’s first season of observations. Angular power spectra of the CMB were obtained from deep integrations of 3 single fields covering a total of 3 deg and 3 shallower surveys of overlapping (mosaiced) fields covering a total of 40 deg. The observations show a damping of the anisotropies at high-l as expected from the standard scenarios of recomb...
PURPOSE This study quantified preschool children's optical quality in terms of their aberrations and modulation transfer function (MTF), and examined the dependence of MTF on pupil size and grating orientation. METHODS Aberrometry was used to measure Zernike coefficients in 34 Chinese preschool children (18 males, 16 females; aged 4.95-6.89 years; mean, 5.91 +/- 0.56). For each subject, after...
چکیده رقابت پذیری معیاری کلیدی برای ارزیابی درجه موفقیت کشورها،صنایع و بنگاهها در میدان های رقابتی سیاسی،اقتصادی و نجاری به حساب می آید.بدین معنی که هر کشور،صنعت یا بنگاهی که از توان رقابتی بالایی در بازارهای رقابتی برخوردار باشد،می توان گفت که از رقابت پذیری بالاتری برخوردار می باشد.در تحقیقات مختلف، رقابت پذیری در سه سطح ملی،صنعت و بنگاه مورد توجه قرار گرفته که در این میان سطح بنگاه از د...
We extend the analysis of the MAXIMA-1 cosmic microwave background (CMB) data to smaller angular scales. MAXIMA, a bolometric balloon experiment, mapped a 124 deg region of the sky with 10 resolution at frequencies of 150, 240 and 410 GHz during its first flight. The original analysis, which covered the multipole range 36 ≤ l ≤ 785, is extended to l = 1235 using data from three 150 GHz photomet...
We have observed collective spin-wave modes in inhomogeneously magnetized Ni0.81Fe0.19 thin-film stripes. The stripes, 18 nm thick and 2 mm wide, are studied in an in-plane magnetic field oriented along their short axes. When the magnetic field is on the order of the shape anisotropy field, the equilibrium magnetization near the stripe edges rotates 90 deg over a length scale of order 100 nm–1 ...
Long-period surface waves are used to map lateral heterogeneities of velocity and anisotropy in the upper mantle. The dispersion curves are expanded in spherical harmonics up to degree 6 and inverted to find the depth structure. The data are corrected for the effect of surface layers and both Love and Rayleigh waves are used. Shear wave velocity and shear polarization anisotropy can be resolved...
field experiments were conducted on an existing subsurface drainage system in roodasht region of esfahan, ian, to test the performance of drain spacing equations for transient flow. the water table profiles recorded from a series of observation wells indicated an essentially flat water surface. the effective hydraulic conductivity and the degree of anisotropy were calculated as 19.2 cm h-1 and ...
introduction low dose rate brachytherapy sources have been widely used for interstitial implants in tumor sites, particularly in prostate. dosimetric characteristics of a new irseed 125i brachytherapy source have been determined using the lif thermoluminescent dosimeter (tld) chips. materials and methods dose rate constant, radial dose function, and anisotropy function around the irseed 125i so...
at early stages of new product development, the effort tooptimize is low and effects on the whole innovation process are high.therefore, a deeper understanding of fuzzy front end and its successcan help firms to be more successful in developing new products. wepresented and tested a conceptual model of relationships among keyvariable sre lated to the fuzzy front end,execution phase of new produ...
