We describe the thermal modeling of a crate hosting boards with Associative Memories (AM) designed for the Fast Tracker Trigger (FTK) system of the ATLAS detector at the CERN Large Hadron Collider. FTK is a highly paralleled hardware system designed to provide global tracks reconstructed in the inner detector. The hardware system is based on AM for pattern recognition and fast FPGAs for track ...

With the development of micro and nanotechnologies, integrated structures based on piezoelectric thin films are widely investigated and their characterization become a crucial issue for the development of new applications. A laser interferometry is here used to assess the mechanical response in quasistatic regime of a piezoelectric sample. To complete this experimental approach, a numerical ...

定量分析生物颗粒形态的变化可以为疾病诊断提供依据。例如血红细胞形态的变化常常会伴随有相应的血液疾病，细胞的癌变常常伴随有细胞核形态的变化等等。无标记的光学显微成像技术已经可以对生物颗粒的尺度和形状进行直接测量。光声显微成像技术 (PAM) 利用生物颗粒固有的吸光本领，已经可以对单个生物颗粒（如细胞和细胞器）进行成像。 最近，光声流式仪(the photoacoustic flow-cytometry)已经实现了对单个生物颗粒进行连续检测。然而，为了在大量的生物颗粒中快速检测生物颗粒的形貌，最好的方法是并非对其进行直接成像，而是采用高频光声显微技术，它的分辨率来源于实际测量与光声功率谱的分析。 光声功率谱分析需要通过计算建模来获取。我们使用 COMSOL Multiphysics® 有限元分析软件的声学模块用来建模 MFC7 细胞核的光声功率谱 ...

Organic-rich shale resources remain an important source of hydrocarbons considering their substantial contribution to crude oil and natural gas production around the world. Moreover, as part of mitigating the greenhouse gas effects due to the emissions of carbon dioxide (CO2) gas, organic-rich shales are considered a possible alternate geologic storage. This is due to the adsorptive properties ...

Micro-machined ultrasound transducers have a wide range of applications. As a sensor or actuator they can be used for measuring fluid speed and direction, to mix and excite particles (sonication), for taking images (ultrasonography), for non-destructive testing and many other purposes in wide variety of fields. For this particular study, a simplified model of micro-machined piezoelectric ...

This paper describes the use of structural mechanics capabilities within COMSOL to explore new cooling catheter designs. Cooling catheters may be used to save ischemic tissue resulting from strokes or heart attacks. Typical guide catheters use metallic braiding to ensure torsional strength. Braiding, however, displaces space for flows and limits design options. To explore alternatives to ...

Thermal ablation in the head and neck requires accurate thermal dose delivery to target tissue while protecting the structure and function of nearby tissue and organs. In this study, we present a method that allows importing Computed Tomography (CT) scans to COMSOL, in order to model accurately the expected pathological outcomes prior to thermal ablation treatment. Thermal ablation of a virtual ...

The present work focuses on modeling a new experimental technique: Scanning Electro-chemical Potential Microscopy (SECPM), which is used to probe the potential profile of the electric double layer (EDL). We used an electrostatic approach to compute the EDL potential measured within the metallic probe. Also, we investigated the effect of the interaction of the electrode/probe double layers on the ...

In volcanic areas, the presence of heterogeneous materials and high temperatures affect the rheological behaviour of the Earth's crust that calls for considering the anelastic properties of the medium surrounding the magmatic sources. A thermo-mechanical numerical model is performed for evaluating the temperature dependency of the elasto-plastic solution. Both temperature distributions and ...

This paper presents a novel methodology towards the design, analysis, and the fabrication process involved in developing a cost effective method to create a piezoelectric actuator by means of the flexoelectric effect. The basic physical equations of the flexoelectric effect and the qualitative analysis of the flexoelectric actuator are done using COMSOL Multiphysics. This effect is used to align ...
