EXPERIMENTAL ANALYSIS OF TURBULENT FLOW HEAT TRANSFER IN A RECTANGULAR DUCT WITH AND WITHOUT CONTINUOUS AND DISCRETE VSHAPED INTERNAL RIBS
"... In this present work, Experiments were performed to collect heat transfer and friction data for forced convection flow of air in rectangular duct with and without internal ribs. The analysis was conducted within the range of Reynolds number from 3000 to 18000. The horizontal rectangular duct was sub ..."

was subjected to constant and uniform heat flux. Experimental results for this configuration are reported for three different channels viz., smooth rectangular duct, rectangular duct with continuous V shaped ribs and rectangular duct with discrete V shaped ribs. The effects of internal ribs on the heat
GT200338622 EFFECTS OF DUCT ASPECT RATIOS ON HEAT/MASS TRANSFER WITH DISCRETE VSHAPED RIBS
"... ABSTRACT The present study investigates the effects of rib arrangements and aspect ratios of a rectangular duct simulating the cooling passage of a gas turbine blade. Two different Vshaped rib configurations are tested in a rectangular duct with the aspect ratios (W/H) of 3 to 6.82. One is the cont ..."

is the continuous Vshaped rib configuration with 60° attack angle, and the other is the discrete Vshaped rib configuration with 45° attack angle. The designed aspect ratio of the duct is obtained by changing the height with a fixed width of 150 mm. The square ribs (3 mm) with the pitch to height ratio of 10
The Immersed Interface Method for Elliptic Equations with Discontinuous Coefficients and Singular Sources
 SIAM J. Num. Anal
, 1994
"... Abstract. The authors develop finite difference methods for elliptic equations of the form V. ((x)Vu(x)) + (x)u(x) f(x) in a region in one or two space dimensions. It is assumed that gt is a simple region (e.g., a rectangle) and that a uniform rectangular grid is used. The situation is studied in wh ..."

Heat Transfer In TwoPass Rotating Rectangular Channels (AR=2:1) with Discrete VShaped and Discrete Angled Rib Turbulators
"... ABSTRACT This paper reports the heat transfer coefficients in a twopass rotating, rectangular channel with ribs, applicable to an internally cooled turbine blade. The channel aspect ratio is 2:1. Five different turbulators are studied: 45° angled ribs, Vshaped ribs, discrete 45° angled ribs, disc ..."

G: Models for Discrete Longitudinal Data
 and Chen 6 © 2012 by American Society of Clinical Oncology JOURNAL OF CLINICAL ONCOLOGY
"... This book covers a wide variety of statistical techniques for longitudinal data analysis. The authors, Geert Molenberghs and Geert Verbeke –both well known in this field – have extended their previous textbook (Verbeke and Molenberghs, 1997), mainly focused on linear mixed model for continuous data, ..."

, approximate numerical methods are shown for each model, including a description of its advantages and limitations. Many practical examples are provided in these sections. In addition, Section V presents a set of casestudies (Chapters 17 to 20) showing how different problems, mainly from the pharmaceutical
Large Deviations and Overflow Probabilities for the General SingleServer Queue, With Applications
, 1994
"... We consider from a thermodynamic viewpoint queueing systems where the workload process is assumed to have an associated large deviation principle with arbitrary scaling: there exist increasing scaling functions (a t ; v t ; t 2 R+ ) and a rate function I such that if (W t ; t 2 R+ ) denotes the wo ..."

In addition to standard models holding that attention can select spatial regions and visual features, recent work suggests that in some cases attention can directly select discrete objects.

Computing Simulations on Finite and Infinite Graphs

We show that 2D rectangular automata, which model discrete reactive systems with continuous environments, define effectively presented
