Abstract

Recently, Bike shop only sells bicycle in full bike or you can build it with components that suit you at the shop. However, these days many customer needs e-commerce web so that potential customers or buyers can shop online for their custom build bike. But if they want to see how it built, they have to see it on the shop or see other builds. The main idea of this study is to make a custom build simulation for bicycle web application for bike shop so that potential buyers could do a simulation first before they buy a custom build bike so that they know what components that suits them and know the weight, price and etc. The objective of this study is to make the potential buyer easier to find a bike that suits their needs. The methodology of system design in this study is using Rapid Application Development Method because the method could made the process very fast and always interact with the bike shop owner so that the application right on track. The website application was built by using MySQL Database and PHP programming language. The website is divided into 2 parts, which are one for customer and one for admin for maintaining the app. In this study use Spinwarrior bike shop for the example of the website implementation Index Terms: Bicycle, custom build, simulation, PHP, website.

Abstract

Institute for Research and Community Service, or called LPPM is a forum for researchers to conduct studies with internal and national scales. LPPM UMN is one of the institutions that provide the container for UMN researchers. However, in the LPPM UMN itself still does not have a webbased system that can be accessed anywhere. This website will be able to share knowledge amongst lecturers by downloading study results that have been done before. After collecting all the requirements, an application is designed using the Rapid Application Development for a limited time spent. The application is built by designing a website and applying MySQL database and PHP programming language with CodeIgniter framework 2.2.2. This website is divided into 3 parts; admins, reviewers, and researcher. Admins are able to see the whole proposal which is sent and appoint a reviewer for one of the proposals. Reviewers have some facilities to review research proposals that have been uploaded. Researchers are able to upload a research proposal. Index Terms - LPPM, Knowledge Management, Research, Website.

Abstract

Image segmentation is an important precursor to boundary delineation of medical images. One of the major challenges in applying automatic image segmentation in medical images is the imperfection in the imaging process which can result in inconsistent contrast and brightness levels, and low image sharpness and vanishing boundaries. Although recent advances in deep learning produce vast improvements in the quality of image segmentation, the accuracy of segmentation around object boundaries still requires improvement. We developed a new approach to contour evolution that is more intuitive but shares some common principles with the active contour model method. The method uses two concepts, namely the boundary grid and sparse boundary representation, as an implicit and explicit representation of the boundary points. We tested our method using lumbar spine MRI images of 515 patients. The experiment results show that our method performs up to 10.2 times faster and more flexible than the geodesic active contours method. Using BF-score contour-based metric, we show that our method improves the boundary accuracy from 74% to 84% as opposed to 63% by the latter method.
