A mixture theory is developed for multi-component micropolar porous media with a combination of the hybrid mixture theory and the micropolar continuum theory. The system is modeled as multi-component micropolar elastic solids saturated with multi- component micropolar viscous fluids. Balance equations are given through the mixture theory. Constitutive equations are developed based on the second law of thermodynamics and constitutive assumptions. Taking account of compressibility of solid phases, the volume fraction of fluid as an independent state variable is introduced in the free energy function, and the dynamic compatibility condition is obtained to restrict the change of pressure difference on the solid-fluid interface. The constructed constitutive equations are used to close the field equations. The linear field equations are obtained using a linearization procedure, and the micropolar thermo-hydro-mechanical component transport model is established. This model can be applied to practical problems, such as contaminant, drug, and pesticide transport. When the proposed model is supposed to be porous media, and both fluid and solid are single-component, it will almost agree with Eringen's model. 展开更多

This paper presents an overview of the recent progress of potential theory method in the analysis of mixed boundary value problems mainly stemming from three-dimensional crack or contact problems of multi-field coupled media. This method was used to derive a series of exact three dimensional solutions which should be of great theoretical significance because most of them usually cannot be derived by other methods such as the transform method and the trial-and-error method. Further, many solutions are obtained in terms of elementary functions that enable us to treat more complicated problems easily. It is pointed out here that the method is usually only applicable to media characterizing transverse isotropy, from which, however, the results for the isotropic case can be readily obtained. 展开更多

After the birth of quantum mechanics, the notion in physics that the frequency of light is the only factor that determines the energy of a single photon has played a fundamental role. However, under the assumption that the theory of Lewis-Riesenfeld invariants is applicable in quantum optics, it is shown in the present work that this widely accepted notion is valid only for light described by a time-independent Hamiltonian, i.e., for light in media satisfying the conditions, ε(t) = ε(0), u(t) = u(0), and σ(t) = 0 simultaneously. The use of the Lewis Riesenfeld invariant operator method in quantum optics leads to a marvelous result: the energy of a single photon propagating through time-varying linear media exhibits nontrivial time dependence without a change of frequency. 展开更多

Instead of studying the impact of media on society,the traditional"top down"orientation of most communication studies scholars,this keynote presentation adopted the opposite perspective,exploring the"bottom-up"impact of"society"on"media".Unlike conventional"agenda-setting theory",which suggests that nationally prominent news media set issue"agendas"for other news media and public opinion,and also unlike the"guard dog"view that media essentially protect the interests of political and economic elites,the"community structure theory"explores links between different community(typically city or nation-state)demographics and variations in reporting on critical health concerns.Summarizing his scholarship on health communication presented and published over decades,the speaker outlined community structure theory's illumination of two overall patterns in US and cross-national coverage of health communication issues.In US coverage,broad measures of economically"buffered"privilege(educational,income,or occupational advantage)are linked to"favorable"or"government responsibility"coverage of health issues,and specific measures of"health"privilege(physicians,hospitals)are connected to"favorable"or"government responsibility"coverage promoting selected health issues.In cross-national coverage,specific measures of national"health vulnerability"(such as percent without improved water access,infant mortality rate)are linked to"government"responsibility coverage for selected health issues(human trafficking,water handling/contamination).In addition,broad measures of"macro"vulnerability conditions(agricultural dependence,political instability)are associated with"government"responsibility coverage for a wide range of health issues(genetically modified foods,drug trafficking,condom promotion,and food security).Overall,community structure theory's"bottom up"perspective reveals how the vulnerable are empowered by their demographic alignment with variations in health communication. 展开更多

Software development teams communicate differently by using a variety of communication tools. Successful communication leads to competitive software based on clear and quickly delivered re-quirements, as well as smoothness in bug reporting and explanation. Agile and Waterfall software development approaches have both addressed the importance of communication for their process. However, neither Agile nor Waterfall has guaranteed communication effectiveness during their development lifecycle. In this study we highlight the main differences between Agile and Waterfall approaches in the light of Media Richness Theory (MRT). We also identify the preferred commu-nication tools during a project’s lifecycle using both Agile and Waterfall models separately. A mixed-method approach was employed in this study incorporating quantitative and qualitative data from interviews and a multilingual web-based survey. The results are presented descriptively and statistically and a rank ordering of communication tools based on our participants’ preferences leads to a better understanding of how to select the best tool in a given situation. Thus a new updated MRT ranking model tailored for software development environment was developed, as well as, we conclude that communication tools are employed differently based on project stages and team member’s role. These differences in using communication tools could be also attributed to the type of transferable information or personal preferences. 展开更多
