We construct unconditionally stable, unconditionally uniquely solvable, and secondorder accurate (in time) schemes for gradient flows with energy of the form ∫ Ω(F (∇φ(x))+ 2 2 |Δφ(x)|2) dx. The construction of the schemes involves the appropriate combination and extension of two classical ideas: (i) appropriate convex-concave decomposition of the energy functional and (ii) the secant method. A...

Slope stability analysis is one of the most important problems in mining and geotechnical engineering. Ignoring the importance of these problems can lead to significant losses. Selecting an appropriate method to analyze the slope stability requires a proper understanding of how different factors influence the outputs of the analyses. This paper evaluates the effects of considering the real geom...

OBJECTIVES Once weekly dosing of alendronate has been shown to provide equivalent efficacy to once daily dosing for treatment of osteoporosis in postmenopausal women. Whether patients will prefer weekly dosing to daily dosing for a chronic condition such as osteoporosis has not been studied. The aim of this international study was to assess preference for the weekly or daily dosing regimen of a...

The seepage and slope stability are very important and necessary in the dam dirt are, therefore, in this context, numerous applications to predict and calculate the rate of leakage has been prepared that than the experimental time and cost savings for the analysis of liquids before construction of earth dams need. In this study, safety factors for slope stability software Kaboodwal  plaxis two-...

• Two auditors: one to ask open questions, the other as witness and scribe. • Interview staff individually, establishing their knowledge of trial procedures and incident. Note conflicting information. • Establish key facts: 1. Were participants real and eligible? 2. Did they consent? 3. Are test/clinical measurements/data valid? 4. Was appropriate treatment/intervention given? 5. Was follow-up ...

recently the stepped spillways have been used as an appropriate solution for energy dissipation. in the present study, siahbisheh dam spillway is simulated by using computational fluid dynamic (cfd), in which the mixture method and reynolds stresses model (rsm) turbulence model is used. in the first modeling series the over all steppes slope is constant. the number of the steps is increased to ...

An overview is given of a series of classification systems used for rock slope stability analyses. Calculation methods and parameters used seem not always appropriate for slopes stability and could be improved. Based on this evaluation some new ideas developed of how a system for slope stability assessment could be designed without inherited legacies as parameters related to underground excavat...

dx. The construction of the schemes involves an appropriate extension of Eyre’s idea of convex-concave decomposition of the energy functional. As an application, we derive unconditionally stable and convergent schemes for epitaxial film growth models with slope selection (F (y) = 1 4 (|y| − 1)) and without slope selection (F (y) = − 1 2 ln(1 + |y|)). We conclude the paper with some preliminary ...

A "step dynamics" model is developed for mound formation during multilayer homoepitaxy. Downward funneling of atoms deposited at step edges is incorporated and controls mound slope selection. Behavior of the selected slope differs from that predicted by phenomenological continuum treatments where the lateral mass current vanishes identically. Instead, this current is shown to vary periodically ...

Patient choice is becoming the centre of health policy in the UK and other countries. But there is ambiguity about what choice means. As the term is used in everyday life, choice is the foundation of the doctrine of patient consent. The doctor is responsible for choosing appropriate treatment, and the patient is responsible for choosing (for consenting to or refusing) what is offered and accept...
