When information is abundant, it becomes increasingly difficult to fit nuggets of knowledge into a single coherent picture. Complex stories spaghetti into branches, side stories, and intertwining narratives. In order to explore these stories, one needs a map to navigate unfamiliar territory. We have developed a methodology for creating structured summaries of information, which we call metro ma...

Automatic discovery of physical topology plays a crucial role in enhancing the manageability of modern metro Ethernet networks. Despite the importance of the problem, earlier research and commercial network management tools have typically concentrated on either discovering logical topology, or proprietary solutions targeting specific product families. Recent works have demonstrated that network...

We introduce the Periodic Metro Scheduling (PMS) problem, which aims in generating a periodic timetable for a given set of routes and a given time period, in such a way that the minimum time distance between any two successive trains that pass from the same point of the network is maximized. This can be particularly useful in cases where trains use the same rail segment quite often, as happens ...

Non-metro Missouri has observed a net in-migration in the last decennial period and great part of these immigrants are Latinos. The literature contends that Latinos are being pulled into the rural areas by large agricultural operations and pushed out of urban areas by harsh “context of reception” immigration laws, and low job availability. A livelihood framework factors explaining vulnerabiliti...

Future bimodal fiber-wireless (FiWi) access-metro networks may deploy both radio-over-fiber (RoF) and radio-andfiber (R&F) technologies. RoF networks are rapidly becoming mature, but they fall short of interworking with distributed wireless MAC protocols such as DCF in widely deployed IEEE 802.11 WLANs. While R&F networks are able to avoid this limitation by means of protocol translation at the...

We look at the problem of using accelerometer in smartphones to detect whether the user is at a metro train station or in a metro train. Currently, we have solutions to detect simple activities, such as sitting or walking. Our work for this thesis investigates the more complex problem of discerning “in-train” from “in-metro-station” activities which internally are composed of several simple act...

Hydrogel-based bioadhesives have emerged as alternatives for sutureless wound closure, since they can mimic the composition and physicochemical properties of the extracellular matrix. However, they are often associated with poor mechanical properties, low adhesion to native tissues, and lack of antimicrobial properties. Herein, a new sprayable, elastic, and biocompatible composite hydrogel, wit...

This paper presents a BIM-based Risk Identification Expert System (B-RIES) for metro construction, composed of three main built-in subsystems: BIM extraction, knowledge base management, and risk identification subsystems. The engineering parameter information related to risk factors is extracted from the BIM of a specific project where the IFC standard plays a bridge role between the BIM data a...

The travel patterns of senior citizens in Seoul were analyzed using Automatic Fare Collection (AFC) data. The focus was specifically on mode choices and transfer patterns. The results showed that 99% of trips made by senior citizens (individuals over 65 years old), who were given free subway transit passes, consisted of single-mode trips. The average travel time was 31 minutes, and subway trave...

BACKGROUND Demonstrating the equivalency between the traditional metro-based clerkships within close proximity to the academic health center and the nontraditional rural preceptorships is important. The University of Minnesota has had a 9-month longitudinal rural elective for third-year medical students for 40 years, the Rural Physician Associate Program (RPAP). In the metro area, traditional s...
