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 ...

In a modern IC design, the capability of predicting the temperature profile is critically important as well as cooling and related thermal problems are the principal challenges. To address these challenges, thermal analysis must be embedded within IC synthesis. This paper presents thermal analysis of the FCBGA chip with a 4mm×4mm×0.3mm silicon die. The silicon die dissipates heat flux of ...

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding with analytes in patient samples in order to generate a visual signal if disease-specific antigen is ...

Confinement systems for nuclear waste are usually designed to perform and ensure safety in view of all the assumed design basis events, including fires. Considering waste typology and radioactivity, the goal of the confinement system design is to protect the content of the steel drums against a two hours fire event. At this aim Sogin has chosen to use Fiber Reinforced Concrete (FRC) shells. ...

The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. The strategy is presented, in order to perform a computation that correctly takes the physics into account. In ...

The research project under which the COMSOL simulations are performed deals with multilayer and fine thermal control of an optical reference cavity for space applications. The cavity, made of Ultra Low Expansion glass (Corning ULE), must be kept close to the zero expansion temperature of the glass (close to room temperature). The target can only be met by active control, while leaving the cavity ...

Micro heat sinks can be widely used for cooling in modern microelectronic high heat flux components where the amount of heat generated sometimes exceeds the limit which the system can withstand. Microstructures when introduced into the channels of heat sinks in form of micro fins enhance the heat transfer performance of the heat sinks further. Copper heat sinks with different types of micro fins ...
Multiphysics Between Deep Geothermal Water Cycle, Surface Heat Exchanger Cycle and Geothermal Power Plant Cycle

Within the framework of Groß Schönebeck project in the North German Basin of Germany, multiphysics between deep geothermal reservoir, boreholes, heat exchangers and power plant is crucial to study lifecycle behavior of each component thereafter a later coupling to study lifecycle and recovery of the overall geothermal system. Study is divided into geothermal water cycle, surface heat exchanger ...

A requirement of the building envelope is to act as environmental separator. Energy is one component that we sometimes wish to control. How can this yield passive benefits such as solar heating? This research focuses on control of thermal radiation energy, and the role windows play as transfer medium between indoor and outdoor environments. A novel concept for passively controlling solar ...

Continuous heat treatment is employed in food industry as a key step in the production of selected products, like dairy desserts. The evolution of an aqueous suspension of starch granules along an existing heat exchanger is here studied by 3D modeling of fluid flow, heat transfer and transformation. 3D modeling puts in evidence the role played by the curved tubes (bends) situated between ...
