The topology

The main aim of this study is to investigate utilising root-like architectures to improve the interfacial strength of pin-integrated hybrid composite-metal structures. Joints are critical elements in aircraft structures and require special consideration due to their vital role in the structural integrity of airframes. Although bonded and bolted systems are used commonly in engineering applications, pinning technologies have shown tremendous potential for hybrid joints.

This research work first aims to develop a microgrid architecture integrating dispatchable and non-dispatchable distributed generation units in a series-cascaded manner. Existing control strategies for cascaded microgrids focus on dispatchable type generation only. However, adequate power sharing and voltage regulation of a microgrid containing mixed dispatchable and non-dispatchable cascaded generation units demand new control approaches to achieve operational performance and reliability comparable to the conventional parallel-topology microgrid.

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. Additively manufactured TPU mould is developed to cast complex concrete structures. A planar topologically optimized cantilever and a free-form 3D column are cast using the proposed TPU mould. Good surface quality is obtained for the cast concrete elements, and the moulds can be reused many times after cleaning.

Software-defined networking (SDN) represents a new structure of computer network that simplifies and improves network management by splitting the control plane and data plane. Since SDN is regarded as a new research issue, the application of SDN in practice faces some barriers. Most network devices such as routers and switches that implement SDN functionalities are expensive. An alternative solution in SDN research and experiments is to use network emulators. By using Mininet, an open source network emulator, this study simulates SDN implementations in different environments.

A problem being presented by us in [4] was "Is the Theorem 1.2 true for infinite topological spaces?". In this paper, we will solve the above problem by proving that Rational Squence Topological space is a T1-space, that has πgp-regularity but also non πgp-normality.

The additional network-modifying cation oxide breaking up this network by the generation of nonbridging O atoms and it has a slight effect on the topology of SiOx and OSiy units. Moreover, the diffusion of network- former atom in sodium-silicate melt is anomaly and diffusion coefficient for sodium atom is much larger than for oxygen or silicon atom. The simulation proves two diffusion mechanisms of the network-former atoms and modifier atoms.

Quantifying the multiple processes which control and modulate the extent of oral bioavailability for drug candidates is critical to accurate projection of human pharmacokinetics (PK). Understanding how gut wall metabolism and hepatic elimination factor into first-pass clearance of drugs has improved enormously. Typically, the cytochrome P450s, uridine 5′- diphosphate-glucuronosyltransferases and sulfotransferases, are the main enzyme classes responsible for drug metabolism.

Xuất hiện chính thức từ giữa thế kỷ XIX, Topology là một ngành toán học trẻ có ảnh hưởng đáng ghi nhận trong kiến trúc đương đại. Những lý thuyết hình học Topology, được thúc đẩy nhờ thành tựu của công nghệ kỹ thuật số, vật liệu mới và xây dựng, đã được áp dụng vào quá trình thiết kế kiến trúc theo nhiều cách tiếp cận nhằm sáng tạo những không gian kiến trúc mềm dẻo, đàn hồi, năng động, biến đổi liên tục với các hình thức kiến trúc tự do, dễ uốn, độc đáo và vô cùng mới mẻ.

In this paper, we focus on studying the mechanisms for routing in IP over WDM networks. Based on analyzing the routing mechanisms of overlay model, we propose a routing algorithm called MHLR (Min-Hop Lightpath Routing) which used for the case of traffic is routed on the virtual topology of IP layer. The objective of MHLR is minimize blocking probability of connection requests in the networks, improving on efficiently utilize the resource of WDM optical networks.
