With the deepening of research on network theory, scientists have gradually begun to adopt complex networks to look at complex systems in nature. A complex network is a network of a large number of closely related and interacting units. This paper believes that each component of the software can be abstracted into various algebraic components. These algebraic components are assembled into a software system. Its assembly process satisfies the configuration and fit characteristics in the topological space. Using algebraic components as the vertices of complex network graphs, the connection relationship between them is taken as the edge of the complex network graph. Using this new perspective, the software system is regarded as a complex network graph composed of algebraic components and their connection relationships. We have proved that the software system can be abstracted into the form of algebraic component expressions, and can find algebraic components that may have vulnerabilities based on the eigenvalues of complex networks.

In the rapid development of society today, along with the popularization of computer technology and the extensive application of the Internet, all walks of life are applying the computer management system to their own enterprises. As a member of the service industry, the hotel industry is also developing rapidly. In order to integrate the rapid development of computer network and hotel industry, to provide better service to consumers and to improve the management efficiency of hotels, hotel room information management systems have emerged. This article describes a management platform for hotel room's online booking and guest information using kendo UI front-end framework design. Using SSM (Spring, Spring MVC, MyBatis) framework to deal with background programs. The overall mission of system development is to ensure office staff can quickly and easily complete the hotel guest room management task, providing better and faster service for residents. The interface is simple and his operation is easy to maintain.

The tolerance of device morphology in wafer-level bonding through polymer-coated layer was investigated for the application of 3D integration. Several different pillar heights were fabricated on wafers to simulate the case of bonding with real devices on wafers. Overall, the wafer morphology with polymer-coated layer above devices less than 2 μm can achieve excellent bonding quality. Furthermore, undamaged carrier wafers can be obtained after laser-assisted de-bonding technology and post clean treatment. Based on bonding results, this research can provide a practical concept on device morphology for polymer-based temporary wafer-level bonding in 3D integration.

A novel amorphous silicon temporary bonding and corresponding laser assisted de-bonding technology are investigated for the improvement of 3D integration. Excellent bonding results with real device wafer with α-IGZO thin-film transistor are shown at the bonding temperature of 210°C, as well as outstanding performances for bonding strength, thermal stability, reliability and chemical resistance. Laser ablated amorphous silicon is proved stable and ultra-fast. Advantages of excellent bonding quality, lower cost and higher throughput demonstrate that this scheme can be a potential candidate in 3D integration platform.

A submicron photolysis polymer temporary bonding with ultra-fast laser de-bonding process of less than 20 s has been demonstrated where both photolysis polymer and polyimide are served as release layer and adhesive layer, respectively. In addition, the bonded structure provides high chemical resistance and mechanical strength for handling process. By measuring the electrical characteristics of devices before and after de-bond, it shows promising performance without degradation. Thus it can be a potential candidate for temporary bonding and de-bonding in 3D integration.

An ultra-fast temporary bonding and release process was investigated for the improvement of 3D integration. The bonding scheme composes of two different kinds of polymer for release layer and adhesive layer. The submicron release layer is a positive photoresist with the characteristic of high UV absorption induced into the de-bonding procedure within 20 s. In addition, the adhesive layer provides robust mechanical strength for the wafer thinning process. Based on results, this structure is a potential candidate for temporary bonding and de-bonding technique in 3D integration.

This paper proposes an novel idea to develop application. Different from traditional programming methods, users can design their application without long term training. The tool prevents syntax and semantic errors during design the application. Based on the proposed idea a total solution to develop application for android system is established. The system includes a cloud system, user management system, web base development tool and an auto deploy system. By means of simply drag and drop, users can design and deploy their application. The architecture also provides flexibility to change the application target with modify the language layer.

A novel boundary determination algorithm (BDA) for robust lane detection is presented. The algorithm can track a complete lane boundary based on partial lane edge points provided there exist sufficient orientation similarity there between. BDA mainly comprises two parts: (a) utilizing an edge detection method to extract orientations and coordinates of edge points; (b) repeatedly applying two circular masks, i.e., a probing circular mask followed by a tracing circular mask, to collect two separate sets of orientations of edge points and from which to sift out a primary orientation for tracking a curve as perceived by human eyes. The algorithm is characterized in that the probing circular mask acts to probe ahead for the tracing circular mask in order to avoid deviation from the right track.

Why edge feature is considered far most important for establishing a perceptual contour in human vision system is based on two dependent viewpoints (a) robust ability to define/extract edges from heterogeneous objects or textures and (b) a subsequent step to decide which edges are significant enough to be preserved for object perception, namely the perceptual edges. In this paper, we present a method not only capable of finding perceptual edges but also allowing them to be used for constructing contours with good continuity. The method mainly comprises two stages: (i) a linear mask filter and non-linear filters (median filter and morphology) are applied to obtain fine-and coarse-edge features, respectively. (ii) An algorithm based on Entropy-weighted Bayesian decision making used to determine perceptual edges is carried out. Extensive simulation results are provided to show noise resistance, and the capability of approximating human visual perception is revealed by testing results of gestalt images.

We propose subarea tree routing (STR), a new routing protocol for multihop wireless ad hoc networks. The novelty of the STR protocol is to divide the whole network into many subareas constructed as a result of establishing subarea trees. Its main idea is to identify root nodes by manual configuration or auto-discovery process firstly, then the root nodes originate the process of establishing subarea trees, and finally each node either joins in a subarea tree or become an interconnect node. STR belongs to hierarchical routing protocol and does not attempt to consistently maintain routing information in every node. Furthermore, through the use of tree?s intrinsic routing function, the STR protocol exhibits hybrid behavior of proactive and on-demand routing protocols. Our simulation results show that the proposed scheme achieves lower route discovery delays, lower route discovery load and better performance of normalized routing load in large, mobile, ad hoc networks as compared with AODV.
