Software systems are growing in size and complexity. Increased complexity often leads to decresed mainainability and bad modularity, and re-engineering tasks is often performed in order to increase the key qualities of the system. With the incentive of a growing attention to aspect-oriented programming, the efforts to devise new techniques for refactoring legacy system into an aspect-oriented d...

The fibula free tissue transplant has been used in mandibular reconstruction for several decades. Various techniques exist to shape and contour the fibula to restore continuity to the segmental mandible defect. Recently, virtual surgical planning has introduced the ability to use cutting guides to contour and create osteotomies for fibula free tissue reconstruction of the mandible. In this arti...

The number of total knee replacements is going to increase in coming decades. Hence there is a need for proper and accurate method of surgical techniques to avoid the complications such as instability and malalignment which leads to a secondary procedure. Use of Computer Navigation provides a more reliable source of intra operative measurement and corrections of deformity. Robotic and hand held...

Dependable computer based systems employing fault tolerance and robust software development techniques demand additional error detection and recovery related tasks. This results in tangling of core functionality with these cross cutting non-functional concerns. In this regard current work identifies these dependability related non-functional and cross-cutting concerns and proposes design and im...

In the successful branch-and-cut approach to combinatorial optimization, linear inequalities are used as cutting planes within a branch-and-bound framework. Although researchers often prefer to use facet-inducing inequalities as cutting planes, good computational results have recently been obtained using disjunctive cuts, which are not guaranteed to be facet-inducing in general. A partial expla...

This research aimed to determine when kinetic changes place greatest risk for noncontact ACL (anterior cruciate ligament) injury during football cutting in match play. Fourteen professional football players undertook three trials of a straight line run and sidestep cutting at 30° and 60° with standardised velocity on an approved football surface. Two types of standardised studded football boots...

In metal cutting industries, mathematical/statistical models are typically used to predict tool replacement time. These off-line methods usually result in less than optimum replacement time thereby either wasting resources or causing quality problems. The few online real-time methods proposed use indirect measurement techniques and are prone to similar errors. Our idea is based on identifying t...

The concerns of persistence and distribution commonly surface in many non-trivial applications are often cross-cutting in nature. It is widely accepted that both concerns can be effectively localized through aspect-oriented techniques, however, there exists very little real-world examples of this phenomenon. How can aspects help in building new distributed systems? How can aspects be used to de...

Artificial mosaics can be generated making use of computational processes devoted to reproduce different artistic styles and related issues. One of the most challenging field is the generation of an artificial mosaic reproducing some ancient and well known techniques starting from any input image. In this paper we propose a mosaic generation approach based on gradient vector flow (GVF) properly...

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...
