Inspired by recent TSG GERAN (Technical Specification Group GSM EDGE Radio Access Network) contributions, we propose a multiple–input multiple–output (MIMO) transmission scheme for GSM/EDGE (Enhanced Data Rates for GSM Evolution) with two antennas on each side. Performance is compared to that of single–antenna transmission with one and two receive antennas, respectively. Also, an approximation ...

This study was aimed to investigate the fundus changes of patients with pregnancy-induced hypertension syndrome (PIHS) using optical coherence tomography (OCT) technology and contrast sensitivity (CS) tests.Ninety-eight patients with PIHS underwent routine eye examinations including vision correction, fundus examination, OCT, and CS tests. The CS test was performed at low, medium, and high freq...

We present here a new ultrasonic diagnosis technique in natural, porous rocks. This method, based on the ultrasonic velocity changes, allows us to measure the transient spacial distribution of two liquids (water and oil) in a sandstone.

Abstract In this paper we study removable singularities for solutions of the fractional heat equation in spacial-time space. We introduce associated capacities and some its metric geometric properties.

In the process of constructing and applying the GIS, the data is the object of the GIS operation and the basis of the science decisionmaking and analysing so that the data quality is determined the success or failure of the whole system application. Any indeterminations in the data layers can diffuse through analysing and combining with other error source. It makes risks to decisionmaking. The ...

In this present study, we fabricated an LSI-based amperometric chip device with highly temporal and spacial resolution for electrochemical imaging, applied to detection of alkaline phosphatase (ALP) activity and respiration activity of embryonic stem (ES) cells.

We consider the problem of determining a pair of functions (u, f) satisfying the heat equation ut−∆u = φ(t)f(x, y), where (x, y) ∈ Ω = (0, 1)× (0, 1) and the function φ is given. The problem is ill-posed. Under a slight condition on φ, we show that the solution is determined uniquely from some boundary data and the initial temperature. Using the interpolation method and the truncated Fourier se...

The new concept of multinode moment matching (MMM) is introduced in this paper. The MMM technique simultaneously matches the moments at several nodes of a circuit using explicit moment matching around = 0. As compared to the well known single-point moment matching (SMM) techniques (such as asymptotic waveform evaluation), MMM has several advantages. First, the number of moments required by MMM ...

The direct benefits of infrastructure in developing countries can be large, but if new infrastructure induces in-migration, congestion of other local publicly provided goods may offset the direct benefits. Using the example of rural household electrification in South Africa, we demonstrate the importance of accounting for migration when evaluating welfare gains of spatial programs. We also prov...
