LOCALIZED PATTERNS OF THE CUBIC-QUINTIC SWIFT-HOHENBERG EQUATIONS WITH TWO SYMMETRY-BREAKING TERMS

Annals of Applied Mathematics 2018年第1期34卷 94-110页

作者： Yancong Xu Tianzhu Lan Zhenxue Wei Dept.of Math. Hangzhou Normal University School of Computer Science and Software Engineering East China Normal University

Homoclinic snake always refers to the branches of homoclinic orbits near a heteroclinic cycle connecting a hyperbolic or non-hyperbolic equilibrium and a periodic orbit in a reversible variational system. In this paper, the normal form of a Swift-Hohenberg equation with two different symmetry-breaking terms （non-reversible term and non-k-symmetry term） are investigated by using multiple scale method, and their bifurcation diagrams are initially studied by numerical simulations. Typically, we predict numerically the existence of so- called round-snakes and round-isolas upon particular two symmetric-breaking perturbations.

Several vision-based structural health monitoring (SHM) approaches have been developed since early 1980s. With the advancement and wide availability of digital video cameras, compounded with the development and enhancement of image analysis methods, vision sensor as a new approach of using a video camera has become a viable alternative and/or complementary method to remotely capture the motions of the structure. This paper presents the methods of applying computer vision algorithms and the development of the software tool for extracting the displacements, strains, velocities and accelerations of the desired points or areas (templates) from video images, demonstrates the applications of the approach for monitoring a highway bridge, explains the challenges in developing robust and accurate vision sensor as an effective solution for SHM practice. © APWSHM 2018.

In recent years, the design of all-optical circuits has received a great attention among the researchers due to high-speed and low-power characteristics and compatibility with CMOS technology. Some combinational logic circuits like adders, subtractors, multipliers, multiplexers, which are useful in optical communication network in data centers and high-perform computers, have been designed using optical components. There are two different design styles, called as Design1 (based on conventional truth-table based approach) and Design2 (based on binary decision diagram). In this paper, four different all-optical multipliers have been explored for array multiplier and carry save adder (CSA)-based multiplier based on these two design styles, using semiconductor optical amplifier (SOA) based Mach-Zender interferometers (MZIs). Simulation results confirm that MZI-based CSA multiplier Design1) has the lowest optical cost and delay compared to those of other three multiplier designs (CSA multiplier - Design2, array multiplier - Design1, array multiplier - Design2) with a precision of 2 or more bits. Further, the proposed all-optical CSA multiplier designs outperform in terms of both optical cost and delay compared to the state-of-the-art designs of all-optical multipliers.

The Internet of Things (IoT), where internet connections are extended to every-day objects, enables collaboration, monitoring, and remote control. An IoT can make a home smart at least in the sense that those in it can be monitored. The question arises of how much and what kind of data are needed to monitor a person as they move about a smart home. This paper focuses on affordances, manifest possibilities for action provided by the environment (e.g., the appearance of a doorknob). Our thesis is that, since the same things are affordances for the monitored and monitoring persons, a little data goes a long way in monitoring a subject's interaction with affordances. This paper describes a scaled-down model of a floor in a smart home equipped with only passive infrared (PIR) motion sensors where nevertheless the data allows high-level interpretation of the subject's activities on that floor.

The Software engineering Body of Knowledge (SWEBOK) provides generally accepted knowledge for the software engineering profession. The SWEBOK had been designed to guide the in-house developers and software contractors but the current trend is that it is being used by the innovators. Thus, the SWEBOK has very little guidance for the emerging role. The focus of the innovators will be to improve the business processes as well as study the business practice to learn the concealed requirements of the customer. This paper is an attempt to analyze the existing proposals on the SWEBOK contents, structure, and make a proposal on what kind of contents it should have, and how it should be structured so that the innovators as well as in-house and software contractors can have proper guidance and can benefit from it.

Nowadays, Dynamic industries like tourism is a enhance to boost many countries economy in recent years. The hotel sector leads to a significant role among all aspects of the tourism industry. Online travel platforms, in association with hotel management, are a part of hotel E-tourism that helps users to make travel plans online, suggest precise recommendations in consideration with the earlier feedbacks upon hotel stay. From the past few months, the user roaming ratio falls rapidly due to the COVID-19 Pandemic across the globe. In a business concern, this Pandemic affects all tourism sectors, specifically in the hotels' occupancy. To retain business positions and attract the users in these problematic scenarios, hotel and travel platform management concerns about past preferences of users, which have a significant impact on gratification for a comfortable stay. The current market trends show that user reviews are playing a vital role to select a hotel based on a safe location. Our work tries to find and recommend the dimensions that contribute more towards higher satisfaction levels of users in Asian continental top tourism city hotels listed by the Master and VISA Inc survey with item collaborative filtering and regression techniques based on Tripadvisor reviews from social media in recent times. The outcome of the work is helpful for Asian continental hotel management to concentrate more on the dimensions for obtaining better reviews. From an online travel platform perspective, this work suggests the contexts for the travel recommender system to gain things effectively from users.

Project management core knowledge areas are known to all. Project Management Body of Knowledge (PMBOK) [6] has prepared these knowledge areas considering all types of projects in mind. Currently, we find that software projects have come with certain level of uncertainty. For many of the software projects which are in the phase of innovation have to user requirements, no budget and no specific time frame. Thus typical project management might not enough for such projects. In this paper, we have proposed additional knowledge area for software project management named Marketing Analysis. We strongly believe that adopting the activities of the proposed knowledge area software firms would be able manage their software project more efficiently and effectively.
