This paper describ esa new search algorithm, Dual Dijkstra Search. F roma given initial and nal conguration, Dual Dijkstra Search nds various paths which have di er enttop olo giessimultaneously. This alo grithm allows you to enumerate not only the optimal one but variety of meaningful candidates among local minimum paths. It is based on the algorithm of Dijkstra[10], which is populary used to ...

statement of the problem: the stability of orthodontic treatment depends on preserving the patient’s pretreatment arch form and arch size during and after treatment. purpose: this investigation was aimed to study the size and shape of iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...

intra-oral appliances such as transpalatal arch and nance appliance fail to resist against forces that tend to loosen the anchorage. the infirmity arises due to the long lever arm and the mesial force that is perpendicular to the long axis of the appliance. the butterfly arch is presented here as an intra-oral appliance that withstands the mesially directed forces with a mechanism that puts str...

South Africa is a cornucopia of the platinum group metals particularly platinum and palladium. These metals have many unique physical and chemical characteristics which render them indispensable to technology and industry, the markets and the medical field. In this paper we carry out a holistic investigation on long memory (LM), structural breaks and stylized facts in platinum and palladium ret...
