Since there is no model available for mixed differential-mode and common-mode transmission, this report gives a measurement setup to determine the channel transfert function of the differential-mode and common-mode channels, as well as the leaked channel from the differential-mode to the common-mode and conversely at the transmitting end and the receiving end. This measurement setup consists of...

Natural and artificial materials including rocks and cement-based materials such as concrete and cement mortar are affected both physically and chemically by various natural factors known as weathering factors. The freeze-thaw process, as a weathering factor, considerably affects the properties of rocks and concrete. Therefore, the effect of the freeze-thaw process on the physical and mechanica...

Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...

A DECT/Bluetooth multi-standard front-end with adaptive image rejection is described. The front-end is designed and simulated in 0.18 μm CMOS technology. Using a multi-band LNA with zero external components full integration of the front-end is achieved. In high image-reject DECT mode it has a NF of 10 dB consuming a current of 47 mA, while in low image-reject DECT mode a NF of 5 dB is obtained ...

Multiple description (MD) video coding can be used to reduce the detrimental effects caused by transmission over lossy packet networks. A number of approaches have been proposed for MD coding, where each provides a different tradeoff between compression efficiency and error res...

Most application-level data units are too large to be carried in a single packet and must be segmented for network delivery. To an application, the end-to-end delays and loss rate of its data units are more relevant measures of performance than ones speciied for individual packets. From this observation, we introduced the concept of a burst (which subsumes the concept of a block in the ATM lite...

The purpose of this paper is to provide a simple evaluation formula for the asymptotic tail probability of the end-to-end backlog in a packet network with a wide range of traffic flows including fractional Brownian motions (fBms). In the previous paper, the authors proposed the concept of tractable effective bandwidth (tEBW). It is the effective bandwidths (EBWs) of one type and can carry out t...

We experience a major paradigm change in mobile networks. The infrastructure of cellular networks becomes mobile as it is densified by using mobile and nomadic small cells to increase coverage and capacity. Furthermore, the innovative approaches such as green operation through sleep scheduling, user-controlled small cells, and end-to-end slicing will make the network highly dynamic. Mobile cell...

A compact empirical mode decomposition (CEMD) is presented to reduce mode mixing, end effect, and detrend uncertainty in analysis of time series (with N data points). This new approach consists of two parts: (a) highest-frequency sampling (HFS) to generate pseudo extrema for effective identification of upper and lower envelopes, and (b) a set of 2N algebraic equations for determining the maximu...
