Abstract Greedy strategy is an algorithm thinking with local optimization as the core idea, but only when problem has no after-effect, global can be achieved. Therefore, greedy not first choice for researchers to solve problem. Based on strategy, this paper adds mechanism of reverse correction thinking, transfers optimal solution solution, and puts forward a compound integrating thinking. actua...

Many segmentation techniques have been published, and some of them have been widely used in different application problems. Most of these segmentation techniques have been motivated by specific application purposes. Unsupervised methods, which do not assume any prior scene knowledge can be learned to help the segmentation process, and are obviously more challenging than the supervised ones. In ...

The conclusion of classical Debye-Hückel theory that a phase separation may occur in highly unsymmetrical plasmas or electrolytes is shown to be false and to arise from a serious error in the treatment of the interaction of pairs of the most highly charged ions. After an approximate correction for this error, no phase separation is predicted. Specific application to iron in the solar plasmas is...

This is a correction to the proof of Theorem 2.1 of [1]. An error occurred in the " proof " of Lemma 2.2, which is false. The following should replace the proof of (c) (Sect. II, p. 821ff.), which will correct the proof of the theorem: The initial condition is satisfied by the summand in (2.3) coming from the identity permutation id. So what we have to show is σ =id C r

Speeded-Up Robust Feature (SURF) is commonly used for feature matching in stereovision because of their robustness towards scale changes and rotational changes. However, SURF feature cannot cope with large viewpoint changes or skew distortion. This paper introduces a method which can help to improve the wide baseline’s matching performance in term of accuracy by rectifying the image using two v...

The ability to reason about another person’s mental states, such as belief, desires and knowledge – first-order theory of mind – develops between the ages three and four. On the other hand, children need one or two more years to reason about a person who reasons about another person – secondorder theory of mind. Is it possible to accelerate the development of theory of mind? There are several t...

median cleft is the midline cleft of the lip. it develops due to incomplete or failed fusion of the median nasal prominence. it can present with minimal deformities such as involvement of the vermilion border, or complex clefting of the midline structures and brain. median clefts are broadly classified as true and false clefts. this case report describes a rare case of median cleft of the upper...

Pulmonary arterial hypertension (PAH) is a frequent complication of congenital heart disease as a consequence of altered pulmonary hemodynamics with increased pulmonary blood flow and pressure. The development of pulmonary vascular disease (PVD) in this patient population is an important concern in determining operative strategy. Early, definitive surgical repair, when possible, is the best the...
