Using ant colony algorithm to solve TSP (traveling salesman problem) has some disadvantages as easily plunging into local minimum, slow convergence speed and so on. In order to find the optimal path accurately and rapidly, an improved ant colony algorithm is proposed. Experimental results show that the improved ant colony algorithm has better effectiveness for TSP problems solutions.

Hyperpycnal (negatively-buoyant) river inflow into lakes and oceans often develops three-dimensional (3D) plunging flow patterns when laterally unconfined. To determine the 3D pattern characteristics, laboratory experiments of unconfined on a sloping bed were carried out using salinity to control density difference. The complemented by numerical modeling based high-resolution Computational Flui...

Delaminasi adalah sebuah ukuran dari area rusak sekitar lubang (Abdullah, 2019). tinggi bisa mengakibatkan kekuatan struktur yang berkurang. Dalam penelitian ini, akan dilakukan drilling dengan parameter permesinan sesuai dalam kaedah permesinan, selanjutnya observasi citra makro terhadap dihasilkan. Pengujian pada material serat gelas 5 layer, pahat diameter 6.3 mm. Parameter menggunakan varia...

A 32-year-old male patient who was HIV positive presented at the Wits Oral Health Centre complaining of a large swelling of the left submandibular region of three years' duration. The swelling was nontender, soft and doughy on palpation and appeared to be crossing the midline. Bilateral submandibular and submental lymphadenopathy was present. Intraorally the lesion caused considerable elevation...

This paper presents an initial survey of the properties of accretion flows in the Kerr metric from three-dimensional, general relativistic magnetohydrodynamic simulations of accretion tori. We consider three fiducial models of tori around rotating, both prograde and retrograde, and nonrotating black holes; these three fiducial models are also contrasted with axisymmetric simulations and a pseud...

 In this paper, we aresupposed to introduce the definitions of n-fold commutative, andimplicative hyper K-ideals. These definitions are thegeneralizations of the definitions of commutative, andimplicative hyper K-ideals, respectively, which have been definedin [12]. Then we obtain some related results. In particular wedetermine the relationships between n-fold implicative hyperK-ideal and n-fol...

SUPPLEMENTARY FIG. S1. (A) Schematic representation of the position of the nodule. (B) Longitudinal B-mode ultrasound (US) image showing the left inferior pole of the thyroid (white arrow) with a small (Thy2) nodule next to a symptomatic (Thy2) nodule attached to it and partly plunging (asterisk).
