Abstract:
Paper plane has a high potential to be upgraded as a Micro Air Vehicle (MAV). Due to its simplicity, paper plane offers easier design option compared to the biological inspired designs as shown in recent MAV development. However, researchers have underestimate and overlook the basic aerodynamic performance induced by these paper planes. This is due to its common usage as toys and wide range of paper plane design. Thus, the objective for current work is to analyse and compare the aerodynamics forces and its performance for selected paper plane design known as Glider, Wide Stunt Glider Plane and

Abstract:
The O-ring paper plane is viewed as another option of paper planes that have potential to be upgraded as Micro Air Vehicle (MAV). Despite the complexity of the closed wing design, the O-Ring (OR) paper planes are easy to develop by following a certain origami technique. However, the aerodynamics performances for such closed wing design is still open to be explored before it can be upgraded for MAV usage. The aerodynamics complexity of closed wing design combined with various hoop sizing may induced complicated aerodynamics performance for OR paper planes. Thus, the objective of this research i

Abstract:
Simultaneous localization and mapping (SLAM) is a fundamental problem for various applications. For indoor environments, planes are predominant features that are less affected by measurement noise. In this paper, we propose a novel point-plane SLAM system using RGB-D cameras. First, we extract feature points from RGB images and planes from depth images. Then plane correspondences in the global map can be found using their contours. Considering the limited size of real planes, we exploit constraints of plane edges. In general, a plane edge is an intersecting line of two perpendicular planes. Th

The shear strength of the smooth plane is less, and the plane with interlock partly is larger.

Firstly, this paper builds the trajectory model of missile in vertical plane. Secondly, this paper chooses missile control method. Thirdly, the Runge-Kutta method and matlab are used to verify the correctness. And to further analyze the law of motion parameters changed with

Abstract:
The Sierpinski Triangle (ST) is a fractal which has Haussdorf dimension [Formula: see text] that has been studied extensively. In this paper, we introduce the Sierpinski Triangle Plane (STP), an infinite extension of the ST that spans the entire real plane but is not a vector subspace or a tiling of the plane with a finite set of STs. STP is shown to be a radial fractal with many interesting and surprising properties.

Abstract:
We continue to study the cocongruence of -dimensional planes us­ing the Cartan — Laptev method. In an -dimensional projective space , the cocongruence of -dimensional planes can be given by the following equations . Compositional clothing of a given cocongruence by fields of ()-planes : and points allows one to define connections of three types in the associated bundle. In the present paper, parallel transports of an analogue of Cartan plane are studied in the connections of three types. It is proved 4 theo­rems: 1.

Abstract:
The Kurdjumow -Sachs mechanism of martensite transformation is investigated in detail in this paper. The distortion matrixes of the first shear, the second shear and lineal adjustment according to the K-S mechanism are calculated. From the lattice distortion matrix, we can obtain invariant normal planes. According to the assumption that the habit plane is constructed with some of the invariant normal planes, the macroscopic habit plane (225)A is also discussed. The results show that the K-S mechanism can account for the relief effects, habit plane, orientation relationship and the change of st
