Inflationary tendencies of public debt have been the cause an unsettling debate among policymakers in Nigeria. Using autoregressive distributed lag (ARDL) framework, this study attempts to investigate impact total on inflation Nigeria for period 1983–2018. The cointegrating regression results reveal evidence a stable long-run relationship inflation, debt, money supply, interest rate, economic g...

This paper presents new techniques for fast view frustum culling. View frustum cullers (VFCs) are typically used in virtual reality software, walkthrough algorithms, scene graph APIs or other 3D graphics applications. First we develop a fast basic VFC algorithm. Then we suggest and evaluate four further optimizations, which are independent of each other and works for all kinds of VFC algorithms...

this paper studies the effect of flexible linear torso on the dynamics of passive quadruped bounding. a reduced-order passive and conservative model with linear flexible torso and springy legs is introduced. the model features extensive spine deformation during high-speed bounding, resembling those observed in a cheetah. fixed points corresponding to cyclic bounding motions are found and calcul...

this paper presents evidence on mesozoic inversion of basin bounding faults within the taleqan-gajereh-lar paleograben (tglp) in central alborz range. for this purpose, well documented stratigraphy data across the tglp together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. the tglp has evolved through the early and mi...

This paper presents optimizations for faster view frustum culling (VFC) for axis aligned bounding box (AABB) and oriented bounding box (OBB) hierarchies. We exploit frame-to-frame coherency by caching and by comparing against previous distances and rotation angles. By using an octant test, we potentially halve the number of plane tests needed, and we also evaluate masking, which is a well-known...
