In the Multi-Spreader Crane Scheduling Problem (MSCSP), containers with identical dimensions but variable weights are arranged along a grid. A multi-spreader crane is used to lift all containers. The has m > 1 modes. When it in p th mode, can remove adjacent same row at time as long total weight of does not exceed loading capacity ? . Such takes h minutes. It also c , q minutes for switch from ...

Intracanal metallic obstructions that block any further treatment often prevent the clinician from achieving total cleanliness of the root canal system. For the retrieval of these obstructions, most of the methods described suggest creating and enlarging a space around the obstruction to loosen it before its retrieval. This article describes a technique that consists of mechanical abrasion of t...

We propose a realistic generalization of the Maki-Thompson rumour model by assuming that each spreader ceases to propagate the rumour right after being involved in a random number of stifling experiences. We consider the process with a general initial configuration and establish the asymptotic behaviour (and its fluctuation) of the ultimate proportion of ignorants as the population size grows t...

Large marine foundation piles are an important part of offshore structural pile foundations, and their lifting operations have always been a major problem in the construction structures. Based on IHC’s bilateral spreader, this paper proposes scheme “internal external clamping type variable diameter spreader”. It solves poor adaptability spreaders to same specification different pipe diameters. ...

Figure ]. A: After the deflected dorsal segment of the septum is separated vertically from the remainder of the septum, a 3.0-mm Skeeter drill is used to create two small holes in the nasal bone on the side opposite the direction of the deflection. B: The ends of the separated septum are sutured into position with a horizontal mattress suture that is passed through the holes in the nasal bones....
