[Industry research] AdHoc DL : 0: Ad Hoc网是一种不依赖于任何固定基础设施、没有中心控制节点、计算资源受限的新型无线移动网络.基于ECC(elliptic curves cryptography),提出了一个新的适用于Ad Hoc网的具有口令认证和共享口令进化的多方密钥协商方案.口令的一个功能是作为共享信息认证移动节点的密钥,另一个功能是作为对称密钥加密移动节点间的交互信息.共享口令进化机制保证每次认证节点密钥和协商会话密钥时口令的新鲜性和安全性,从而既减轻了移动节点的计算量和存储负担,又实现了移动节点之间的密钥认证和信息加密.新方案具有抗中间人攻击、抗重放攻击、密钥独立和前向安全等多种安全特性.

[Industry research] gardnertimingdetector DL : 0: This paper presents the simulation performance of the all-digital symbol timing recovery using the Gardner Timing Error Detector over π/4-DQPSK modulation. The open loop statistics, the S-curve and the normalized timing error variance, were investigated to show the stable tracking performance of the system. The symbol timing recovery has a second order loop transfer function, which was able to track down phase, and frequency offsets. Modulation was observed to have a performance of 2 dB lower from the theoretical BER curve.

[Industry research] Bezier.pdf DL : 0: The Bézier curve is one of the most commonly used parametric curves in CAGD and Computer Graphics and has many good properties for shape design. Developing more convenient techniques for designing and modifying Bézier curve is an im- portant problem, and is also an important research issue in CAD/CAM and NC technology fields. This work investigates the optimal shape modification of Bézier curves by geometric constraints. This paper presents a new method by constrained optimi- zation based on changing the control points of the curves. By this method, the authors modify control points of the original Bézier curves to satisfy the given constraints and modify the shape of the curves optimally. Practical examples are also given.

[Industry research] NN DL : 0: To improve efficiency, PV system must operate on maximum power point (MPP) so necessary to determine it. Thus, when a direct connection is carried out between the source and the load, the output of the PV module is seldom maximum value and the operating point is not optimal. To overcome this problem, it is necessary to add an adaptation device, an MPPT controller with a DC/DC converter between the source and the load, Fig. 8 [8]. The characteristics of a PV system vary with temperature and irradiance, Fig. 3, 4, 5, 6. Therefore, an MPPT controller is also required to track the new modified maximum power point in its corresponding curve to arrange PV system operate at peak power point so that maximum power can be delivered to load. Whenever, a variation in temperature and/or irradiance occurs.
