high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

In many large-scale enterprise information system solutions, process design, data modeling and software component design are performed relatively independently by different people using various tools and methodologies. This usually leads to gaps among business process modeling, component design and data modeling. Currently, these functional or non-functional disconnections are fixed manually, w...

Gravity drainage is the main mechanism which controls the oil recovery from fractured reservoirs in both gas-cap drive and gas injection processes. The liquid bridge formed between two adjacent matrix blocks is responsible for capillary continuity phenomenon. The accurate determination of gas-liquid interface profile of liquid bridge is crucial to predict fracture capillary pressure precisely. ...

In current AASHTO design practices, bridges are designed on an elemental basis. AASHTO code specifies that each structural element is to be designed for the loads it will experience during the life of the bridge. The calculated loads are enveloped to produce maximum loads. This approach, elemental design, is structurally sound, in general conservative, and has resulted in the design and constru...

OBJECTIVES To assess the impact of a program to integrate introductory pharmacy practice experiences with pharmaceutical science topics by promoting active learning, self-directed learning skills, and critical-thinking skills. DESIGN The Learning Bridge, a curriculum program, was created to better integrate the material first-year (P1) students learned in pharmaceutical science courses into t...

past earthquakes have demonstrated that old rc bridges may be seismically vulnerable. bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. in this research an existing concrete bridge representative of the most common bridges in the highway system in iran are studied. push over and nonlinear ...

5 On September 18th 2008, a replacement for the previously collapsed I-35W bridge opened 6 to the public. Consequently, travelers were once again confronted with the opportunity to find 7 better alternatives. The traffic pattern of the Minneapolis road network was likely to read8 just, because of the new link addition. However, questions arise about the possible reasons (or 9 components in the ...

In this paper, full scale load test of a horizontally curved steel box-girder bridge is carried out in order to detect structural defects, which reportedly result in unwanted vibrations in nearby buildings. The bridge is tested under the passage of six heavy vehicles at different speeds, so as to determine its static and dynamic responses. A total number of one hundred and two (102) sensors are...

Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronary arteries is very rare. We present a patient with more than one myoc...

In current bridge aeroelastic analysis frameworks, predictions of flutter instability and buffeting response to wind fluctuations are treated as two separate procedures. The flutter instability is analyzed through the solution of a complex eigenvalue problem, offering information on how the self-excited forces influence bridge dynamics, especially the modal damping, and eventually drive the bri...
