Description: Attached is a zip file with an OpenGL/ES multi-texture rotating cube I used for a project last year. It rotates a cube and maps multiple textures to the surface, and implements a frame per second counter.-Attached is a zip file with an OpenGL/ES multi-texture rotating cube I used for a project last year.

Description: we present the first 3D discrete curvelet transform. This transform is an extension to the 2D
transform described in Cand`es et al..1 The resulting curvelet frame preserves the important properties, such
as parabolic scaling, tightness and sparse representation for singularities of codimension one. We describe three
different implementations: in-core, out-of-core and MPI-based parallel implementations. Numerical results verify
the desired properties of the 3D curvelets and demonstrate the efficiency of our implementations.

Description: This function implememts Soft Output Viterbi Algorithm in trace back mode
Input:
rec_s: scaled received bits. rec_s(k) = 0.5 * L_c(k) * y(k)
L_c = 4 * a * Es/No, reliability value of the channel
y: received bits
g: encoder generator matrix in binary form, g(1,:) for feedback, g(2,:) for feedforward
L_a: a priori information about the info. bits. Extrinsic info. from the previous
component decoder
ind_dec: index of the component decoder.
=1: component decoder 1 The trellis is terminated to all zero state
=2: component decoder 2 The trellis is not perfectly terminated.
Output:
L_all: log ( P(x=1|y) ) / ( P(x=-1|y) )

Description: ent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.-#import "mapView.h"
