INTRODUCTION Osteochondromas are benign tumours of the skeletal system. Their commonplace of occurrence is around growing ends of long bones like lower end of femur and upper end of tibia, but literature describing their incidence around flat bones of body like pelvis, scapula and small bones of hand, foot is rare. CASE REPORT We describe two cases of osteochondromas at unusual sites, one on ...
Parabolic concentrator mirrors are an important component of many solar energy systems, particularly solar mirror collectors. Precision parabolic mirrors are expensive to fabricate and to transport. Here, a new concept for designing and fabricating precision parabolic mirrors is presented. The mirror is formed from a thin flat very flexible metal sheet with a highly reflective surface. Attached...
Expansions of the gravitational field arising from the development of asymptotically Euclidean, time symmetric, conformally flat initial data are calculated in a neighbourhood of spatial and null infinities up to order 6. To this ends a certain representation of spatial infinity as a cylinder is used. This set up is based on the properties of conformal geodesics. It is found that these expansio...
The Lyme disease spirochete, Borrelia burgdorferi, swims by undulating its cell body in the form of a traveling flat wave, a process driven by rotating internal flagella. We study B. burgdorferi's swimming by treating the cell body and flagella as linearly elastic filaments. The dynamics of the cell are then determined from the balance between elastic and resistive forces and moments. We find t...
Means-ends analysis is a seemingly well understood search technique, which can be described, using planning terminology, as: keep adding actions that are feasible and achieve pieces of the goal. Unfortunately, it is often the case that no action is both feasible and relevant in this sense. The traditional answer is to make sabgoals out of the preconditions of relevant but infeasible actions. Th...
This paper describes our English Speech-to-Text (STT) system for the 2011 IWSLT ASR track. The system consists of 2 subsystems with different front-ends—one MVDR based, one MFCC based—which are combined using confusion network combination to provide a base for a second pass speaker adapted MVDR system. We demonstrate that this set-up produces competitive results on the IWSLT 2010 dev and test s...
Kenmotsu geometry is a valuable part of contact with nice applications in other fields such as theoretical physics. In this article, we study the statistical counterpart manifold, that is, manifold some related examples. We investigate curvature properties manifolds. It has been shown not Ricci-flat by constructing counter-example. Finally, prove very well-known Chen-Ricci inequality for subman...
In this paper, we review Icarus, a cognitive architecture that utilizes hierarchical skills and concepts for reactive execution in physical environments. In addition, we present two extensions to the framework. The first involves the incorporation of means-ends analysis, which lets the system compose known skills to solve novel problems. The second involves the storage of new skills that are ba...
This paper employs Data Envelopment Analysis to measure for the first time the performance of Greek domestic equity mutual funds over four different one-year horizons and for the whole four-year period. In particular, the model used examines whether fund managers employ inputs (i.e. assets, loads, and risk) efficiently to produce output (returns). The results demonstrate that the efficient fund...
