Abstract—In this paper, it took Suzhou University of Science and Technology as an example, designed a real-time virtualcampus roaming system. It discussed the three-dimensional modeling of buildings, gates, roads, bridges, surrounding lawns, trees and other objects on campus, and implemented the data change between 3ds max and VRMLPad. At the same time, it used a model with kinds of texture maps, multi-resolution hierarchy, and achieved the scene using DEF/USE ways of VRML language. This paper focuses on some questions, such as a variety of scene building, scene model and mapping methods, code conversion, optimization techniques, interactive programming based on the triggers, cruise, controlling viewpoints, communication between JAVA and scene etc.
A research approach was adopted in the implementation of this system, from whence a workable circuit was designed. The design was done using embedded system technology. This is to reduce component count, keep the system simple and cost effective. . The system is capable of enhancing level measurement and control. The completed work had been tested and worked satisfactory.
The hardware implementation is performed for the designed values and tested. The gate pulses for a duty ratio of 50% and at a frequency of 31 kHz are generated using Arduino Uno Microcontroller. Also from the hardware implementation, it can be seen that the ripple in the total inductor current is reduced by half, which is from 940m of ripple current of conventional boost converter to a peak-to- peak of 400m for the 2-phase IBC.Thus the 2-phase IBC is able to achieve the objectives of reducing the size of the passive components and decreasing the ripple in input current thus achieves a higher efficiency.
Construction project planning has been considered as a critical process in the early project phases that determines the successful implementation and delivery of project. During this stage, project planners need to develop main construction strategies, to establish construction path and assembly sequences, to arrange construction methods and resources required for the execution of work packages. The Building Information Modeling (BIM) is an architectural, engineering and construction workflow of utilizing information which has been loaded into a building design project. The information in a virtual model is commonly utilized in the areas of building design and engineering, material takeoff and cost estimating. Industry focus continues to be on the 3D value of a model which allows the building team to better plan, design, visualize, and construct the built environment. (J. Vinoth Kumar and Mahua Mukherjee (1). Department of Architecture and Planning, Indian Institute of Technology, Roorkee, India. (IIT), reported (3rdNov 2009).These sophisticated 3D computer models allow the project team to see the finished project before any construction work begins, resolve. Construction clashes, and ensure that every team member understands the design exactly as it was intended. On the job site, BIM allows us to save time, save money, and build higher quality projects through
Engling Yeo et al (2003) compared four different structures for the implementations of the ACS recursion. These inferences are applicable to the implementations of both soft and hard - decision Viterbi decoders. It was found that architectural retiming and transformation of the ACS structures with modification of the register exchange provided the highest throughput without excessive area and power penalties. Although the SOVA has less complexity than the MAP decoder, it still has higher power consumption than the hard- output Viterbi decoder. In practical high performance iterative decoders, the power could be lowered through custom circuit design and technology scaling .
Methods/design: The HDVW Pilot Study will enroll consecutive PD and HHD patients who fulfilled any one of our inclusion criteria: 1. following discharge from hospital, 2. after interventional procedure(s), 3. prescription of anti-microbial agents, or 4. following completion of home dialysis training. Clinician-led telephone interviews are performed weekly for 2 weeks until VW discharge. Case-mix (modified Charlson Comorbidity Index), symptoms (the modified Edmonton Symptom Assessment Scale) and patient satisfaction are assessed serially. The number of VW interventions relating to eight pre-specified domains will be measured. Adverse events such as re-hospitalization and health-services utilization will be ascertained through telephone follow-up after discharge from the VW at 2, 4, 12 weeks. The VW re-hospitalization rate will be compared with a contemporary cohort (matched for age, gender, renal replacement therapy and co-morbidities). Our protocol has been approved by research ethics board (UHN: 12-5397-AE). Written informed consent for participation in the study will be obtained from participants. Discussion: This report serves as a blueprint for the design and implementation of a novel health service delivery model for home dialysis patients. The major goal of the HDVW initiative is to provide appropriate and effective supports to medically complex patients in a targeted window of vulnerability.
The rocker-bogie suspension design has become a proven mobility application known for its superior vehicle stability and obstacle-climbing capability Following several technology and research rover implementations, system was successfully flown as part of Mars Pathfinder’s Sojourner rover. When the Mars Exploration Rover (MER) Project was first proposed, the use of a rocker-bogie suspension was the obvious choice due to its extensive heritage. The challenge posed by MER was to design a lightweight rocker-bogie suspension that would permit the mobility to stow within the limited space available and deploy into a configuration that the rover could then safely use to egress from the lander and explore the Martian surface .

"Campus card" system as an important part of the construction of digital campus, has been popular in major universities. But these storage data do not cause the attention of the majority of managers, most users only concerned about the function of the system, and generated data of the management with not enough attention, there is no analysis of these data implied information. Most of the student management systems used in Colleges and universities do not have the data analysis function of students' campus activities, and so far there is no relatively mature scheme for the analysis of student campus activities. We use data mining technology to mining the campus data generated in the process of using “campus card" system, and using the algorithm of clustering analysis to get the deep information of data, so as to provide more convenient and perfect digital service for school management.
It will also be seen that there is a smoothing capacitor placed on the output. This serves to ensure that the voltage does not vary appreciable, especially during and switch transition times. It will also be required to smooth any switching spikes that occur.Quasi square wave converter- quasi square wave resonant converter also known as quasi resonant converter allow the design of fly-back The subscript for SMPS with a reduced and an improved efficiency at full load. However as the switching frequency when load decrease the frequency excursion must be limited to avoid additional switching losses.
The charge controller intended to design and implement in this research work is a small power charge controller. Figure 2.6 shows the block diagram of the charge controller. The charge controller is built around semiconductor switches (silicon controlled rectifier-SCR) rather the electromechanical switches (relays). The microcontroller is used to control the overcharging of the battery, to display the battery voltage continuously and to make audible alarm when the battery is fully charged. Firstly the battery is charged using high current through the SCR. When the battery almost reaches its full terminal voltage (full charge) high current charging is cut off and slow charging (trickle charging) is still done. At full charge condition the charging is totally cut out by the control of the microcontroller. The current coming from the wind turbine through the converter circuit is diverting to another load (e.g. lamp). By this means the overcharging of the battery is prevented. The constructed charge controller can charge the 12 V battery with up to 6 A of current. The amount of charging current can be increased by changing some components in the charge controller without any difficulty.
and deployment of an enterprise network. With the innovation and diffusion of new technology such as Universal computing, Enterprise mobility, E-commerce and Cloud computing, the network security has still remained as an ever increasing challenge. A Campus network is an important part of campus life and network security is essential for a campus. Campus network faces challenges to address core issues of security which are governed by network architecture. Secured network protects an institution from security attacks associated with network. A university network has a number of uses, such as teaching, learning, research, management, e-library, result publishing and connection with the external users. Network security will prevent the university network from different types of threats and attacks. The theoretical contribution of this study is a reference model architecture of the university campus network that can be followed or adapted to build a robust yet flexible network that responds to the next generation requirements. A hierarchical architecture of the campus network is configured with different types of security issues for ensuring the quality of service. In this project, a tested and secure network design is proposed based on the practical requirements and this proposed network infrastructure is realizable with adaptable infrastructure.
As is detailed later (see section 5.1), the use of several standard, conventional virtual reality features—such as 3D geometry, stereo vision, and head-tracking—were rejected from this project after it was ascertained that they would yield minimal benefit or contribution to the painter training process, yet incur substantial cost in implementation time and detriment to trainer-observer interaction. Instead, it was decided to emphasize visual characteristics of the paint coat—specifically its on-surface behavior (cohesiveness, flow, drying, etc) and visual properties (atomization, reflections, texture, etc)—as they represent the visual feedback elements which paint sprayers are trained to recognize and respond to. The ETRI system does not incorporate these features.
As described earlier, the basic design of this metal detector is a Induction Balance (IB) design. Although multiple coils can be used for a IB metal detector, the system chosen for this group was a two coil design, for simplicity in design and construction. The circuit composes of three basic blocks. The first block consists of oscillator, driver transistor and transmitter coil. The second block consists of receiver coil, signal amplifier, rectifier and sampling capacitor. The last block is made up of display driver and buzzer for audio visual indication (LED array and buzzer). The block diagram of Simple Metal Detector is shown in Fig. 1.
In the IT field, calculus is one of the most important subjects, and the knowledge learnt in advanced mathematics helps students to acquire Calculus more easily as well as providing a smooth transition from secondary to tertiary education. With the low enrolment in and insufficient knowledge about advanced mathematics, students encounter problems in learning calculus at post-secondary level. This project aims to design and implement a m Learning curriculum for calculus, and then examine the effectiveness of this m Leanring tool as a supplement to normal teaching in enhancing students’ academic performance in calculus and calculus-related subjects.

Using Autodesk Revit software to build model relied on BIM technology and Skyline software to design the spatial database relied on 3DGIS technology. A 3D visualization campus information system called smart campus was constructed, which provides feasible solutions for constructing smart campus.
Although MDA has been in use since 2001, model-based engineering is still at an early stage of development and it is unclear whether or not it will have a significant effect on software engineering practice. The main arguments for and against MDE are: 1. For MDE Model-based engineering allows engineers to think about systems at a high level of abstraction, without concern for the details of their implementa- tion. This reduces the likelihood of errors, speeds up the design and implemen- tation process, and allows for the creation of reusable, platform-independent application models. By using powerful tools, system implementations can be generated for different platforms from the same model. Therefore, to adapt the system to some new platform technology, it is only necessary to write a transla- tor for that platform. When this is available, all platform-independent models can be rapidly rehosted on the new platform.

Graphi soft in 1986 introduced its new software as a solution for virtual building. This software, Archi cad, was really a drastic improvement in CAD programs of that time since Archicad allowed the creation of three dimensional (3D) models of projects (Dey, 2010). The terms Building Information Modeling and Building In- formation Model and the acronym of BIM were wide- spread when Autodesk released the "Building Informa- tion Modeling” (Autodesk, 2003).
