This paper studies the reliability of infinite slopes in the presence of spatially variable shear strength parameters that increase linearly with depth. The mean trend of the shear strength parameters increasing with depth is highlighted. The spatial variability in the undrained shear strength and the friction angle is modeled using random field theory. Infinite slope examples are presented to ...

Using linear scaling theory, we study the behavior of response functions extrema in the vicinity of the critical point. We investigate how the speed of convergence of the loci of response function extrema to the Widom line depends on the parameters of the linear scaling theory. We find that when the slope of the coexistence line is near zero, the line of specific heat maxima does not follow the...

PURPOSE To perform ultraviolet (UV) macrophotography of the normal in vivo human cornea, establishing biometric data of the major component of UV absorption for comparison with the Hudson-Stähli (HS) line, the distribution of iron demonstrated by Perl stain, and cases of typical amiodarone keratopathy. METHODS Nonrandomized comparative case series of UV photographs of 76 normal corneas (group...

BACKGROUND Anterior cruciate ligament (ACL) loading during drop landing has been recently studied with a sagittal plane knee model developed by Kernozek and Ragan using mean anatomical and physiological parameters obtained from cadaveric and clinical data. It is unknown how estimates in ACL load may be altered due to variations in anatomical and physiological parameters used from other research...

Understanding digital lines comprises two components: i) determining whether a given digital set is a digital line segment, i.e. whether there exists a real straight line in IR2 that digitizes to it, and ii) recovering the space of straight lines which digitize to a given digital line segment. Although these problems have been extensively studied by researchers in computer vision and digital ge...

To study the influence of diet composition on regulation of body weight, we fed 21 weight-stable subjects (11 lean, 10 obese) high-carbohydrate (HC) and high-fat (HF) diets for 1 wk each. Although diet composition was fixed, total energy intake was unrestricted. Subjects had a higher energy intake on the HF (11,039 +/- 2700 kJ/d) than on the HC (10,672 +/- 2617 kJ/d) diet (P less than 0.05), bu...

In practical applications of item response theory (IRT), item parameters are usually estimated first from a calibration sample. After treating these estimates as fixed and known, ability parameters are then estimated. However, the statistical inferences based on the estimated abilities can be misleading if the uncertainty of the item parameter estimates is ignored. Instead, estimated item param...

In an axisymmetric CO2-N2-H2O gas dynamic laser, let ? denote the intersection of the vertical plane of symmetry with the upper part of the (supersonic) nozzle. To obtain a maximal small signal gain, some authors have tested several families of curves for ?. To find the most general solution for ?, an application of Pontryagin’s principle led to the conjuncture that the optimal ? must consist o...

The problem studied here is a member of a large class of on-line decision problems. The basic question is to choose from two possible alternatives at a given instance, for the use of an item. This choice is based solely on previous experience. One alternative di ers the permanent acquisition of the item (rents it) and has a small recurring xed cost (rent) associated with its use. The other choi...

As an integral component of sustainable manufacturing, recycling and remanufacturing have been gaining popularity in line with Green initiatives. While the importance of item-level information their success has been stressed, the potential of RFID technology in recycling/remanufacturing has not received much attention in the research literature. We attempt to address this gap by considering RFI...
