The paraseismic effect due to civil structures construction may cause cracks in buildings around the source of the vibration. The vibrations velocities of the source transmitted to the surrounding buildings can be used as excitation to the numerical simulations. In the paper the case study of the assessment of the real civil structure dynamic simulation is presented. The response is evaluated and compared to the critical values in national standards.

By construction or by reconstruction of civil structures can be paraseismic load generated. This effect may causes cracks in buildings standing near the source of the vibrations. Numerical simulation is one of the possibilities how can be this problem analyzed. The vibrations velocities of source transmitted to the surrounding buildings can be used as excitation to the numerical simulations. In the paper is presented the case study of the assessment of the tension forces in load bearing cables in real civil structure. This estimation is based on theoretical and experimental dynamic equations comparison.

Abstract IR-OBIRCH (Infrared Ray – Optical Beam Induced Resistance Change) is one of the main failure analysis techniques [1] [2] [3] [4]. It is a useful tool to do fault localization on leakage failure cases such as poor Via or contact connection, FEoL or BEoL pattern bridge, and etc. But the real failure sites associated with the above failure mechanisms are not always found at the OBIRCH spot locations. Sometimes the real failure site is far away from the OBIRCH spot and it will result in inconclusive PFA Analysis. Finding the real failure site is what matters the most for fault localization detection. In this paper, we will introduce one case using deep sub-micron process generation which suffers serious high Isb current at wafer donut region. In this case study a BEoL Via poor connection is found far away from the OBIRCH spots. This implies that layout tracing skill and relation investigation among OBIRCH spots are needed for successful failure analysis.

Corporate Practice

The current graphical rhetoric of advertising includes everything from images of the globe borrowed from the US space program (for example, Hewlett-Packard Corp. computer systems), to pseudotribal renderings of a very different sort [for example, Minute Maid's (The Coca Cola Co.) Fruitopia]. The use of these images are part of what Goldman calls the economy of ‘commodity signs’, where produced meanings are linked to commodities through the medium of the print or broadcast advertisement. The increased incorporation of global images in Western advertising presents an opportunity to analyze the ideological underpinning of the ‘new global economy’. The sheer volume of purchased advertising space places these often confusing images before our eyes at an increasing pace, producing meanings which tend to obfuscate and fetishize discourse related to globalism. A decoding of specific advertisements with the use of the Hewlett-Packard Corporation as a case study, juxtaposed against the real spatial practices of the company will reveal ruptures, contradictions, and incoherence in advertising messages which appropriate the symbolic power of global images.

Effective Use

The process of designing a sail can be a challenging task because of the difficulties in predicting the real aerodynamic performance. This is especially true in the case of downwind sails, where the evaluation of the real shapes and aerodynamic forces can be very complex because of turbulent and detached flows and the high-deformable behavior of structures. Of course, numerical methods are very useful and reliable tools to investigate sail performances, and their use, also as a result of the exponential growth of computational resources at a very low cost, is spreading more and more, even in not highly competitive fields. This paper presents a new methodology to support sail designers in evaluating and optimizing downwind sail performance and manufacturing. A new weakly coupled fluid–structure interaction (FSI) procedure has been developed to study downwind sails. The proposed method is parametric and automated and allows for investigating multiple kinds of sails under different sailing conditions. The study of a gennaker of a small sailing yacht is presented as a case study. Based on the numerical results obtained, an analytical formulation for calculating the sail corner loads has been also proposed. The novel proposed methodology could represent a promising approach to allow for the widespread and effective use of numerical methods in the design and manufacturing of yacht sails.
