Snakes are active contours in the 2d image plane. Starting from an initial estimate of a curve's shape and position they move to salient image features in an iterative process driven by minimization of an energy function. The twin snakes concept is an extension to traditional snakes. Twin snakes are designed for detecting two parallel contours simultaneously and are useful for line extraction i...

The building sector accounts for over 40% of global energy consumption, and many buildings are old inefficient. However, the current pace renovation is not sufficient to make a tangible impact. A new strategy needed accelerate process. Renovation at district level use digital tools, such as twin (DT) city district, can provide solution. This paper proposes novel approach block using renewable s...

BACKGROUND The use of functional appliances for the correction of retrognathic mandible is very common in orthodontics. Similar appliances known as oral appliances are also frequently used in adults for the treatment of mild to moderate obstructive sleep apnea (OSA). Many studies have reported improvement of pharyngeal airway passage (PAP) dimensions following functional appliance therapy in ch...

A block graph is a graph whose blocks are cliques. A block duplicate (BD) graph is a graph obtained by adding true twins (i.e., adjacent vertices with the same closed neighborhood) to vertices of a block graph. If each cut-vertex belonging to three or more blocks in the block graph receives at most one true twin, the resulting graph is called a restricted block duplicate (RBD) graph. BD and RBD...

The multiple relationships within kinships of adult monozygotic twins permit incisive analyses to be made of genetic and environmental effects on behavioral traits. Data from families of 65 monozygotic twin pairs yield evidence of genetic variance on the Block Design Test, a nonverbal measure of general intelligence.

Two case reports illustrate the effective treatment of Class II division 2 malocclusion with modifications to the Twin Block appliance. This approach may reduce the total treatment time and reduce the need for extra-oral anchorage. In each of the cases presented treatment has been carried out on a non-extraction basis with full correction of the malocclusion.

Ultrasound has revolutioned the care of women carring twins. First trimester evaluation is the best time to determine chorioniocity and amnioniocity in multiple gestations. First trimester diagnosis is based on the number of gestational sacs, amnions and yolk sacs. Growth rate in multiple multiple gestations during the fist and early second trimesters parallels the growth rate of singleton preg...
