Contaminant transport analysis was performed for four selected solid waste landfill designs using the computer code POLLUTE. The diffusion coefficients were determined for the natural soils (aquitard) and compacted soils from the Urumia landfill site, using the diffusion tests. These coefficients along with the geometrical, physical, and chemical parameters of the natural soil and engineered la...

Through Strand7 ABAQUS finite element analysis, geometrical layout beam material effects on are thor...

Brilliant beams of hard x-rays, with geometrical cross-sections below 50×50 nm, are a standard research tool for synchrotron users. With the advent of lower emittance sources, such as NSLSII, Petra III and Max IV, and planned upgraded lattices, such as APS-2, SPING8-II, ESRF II and DLS II, nanofocusing optics operating in transmission mode will become more competitive than they are currently. I...

Partial shading in photovoltaic modules is an important reliability and performance concern for all photovoltaic technologies. In this paper, we show how cell geometry can be used as a design variable for improved shade tolerance and performance in monolithic thin film photovoltaic modules (TFPV). We use circuit simulations to illustrate the geometrical aspects of partial shading in typical mon...

Art in the twentieth century was associated with all aspects of life between cultural, intellectual and social, end nineteenth beginning century, which witnessed a great revolutionary transformation science, industry technology And Nouveau appeared, is an art that combines fine arts applied without mimicking nature, but translating it into expressive lines spaces to enrich decorative aspect rea...

In this work, the natural geometric relation between the space time block code design for the unknown channel at the receiver and its counterpart design for the known channel at the receiver is exploited, to establish an estimate on the corresponding diversities. This leads to a decomposition result and splits the code design problem into two complexity reduced sub tasks. Moreover a geometrical...

I present an Hipparcos color-magnitude diagram (CMD) that is color-coded by transverse velocity v ⊥. This illustrates the connection between the photomet-ric and kinematic properties of various stellar populations in a manner that is particularly suitable to introductory astronomy courses.

The purposes of inlet and outlet devices for rotary blood pumps, including inducers and diffusers for axial pumps, inlet and exit volutes for centrifugal pumps, and inlet and outlet cannulas, are to guide the blood into the impeller, where the blood is accelerated, and to convert the high kinetic energy into pressure after the impeller discharge, respectively. The designs of the inlet and outle...

In this work, the geometric relation between space time block code design for the coherent channel and its noncoherent counterpart is exploited to get an analogue of the information theoretic inequality I(X;S) I((X;H);S) in terms of diversity. It provides a lower bound on the performance of non-coherent codes when used in coherent scenarios. This leads in turn to a code design decomposition res...
