Scatterer size estimation is useful when characterizing tissue using ultrasound. In all previous studies on scatterer size, the estimations are performed in the frequency domain and are thus subjected to a trade off in time-frequency resolution. This study focused on the feasibility of estimating scatterer size in the time domain using only the ultrasound center frequency, assuming a Gaussian-shap

The LHCb system requires high efficiency muon detection into LHC bunch crossing: 95% into a 25 ns time window. To reach such efficiency many parameters of the detector readout apparatus have to be calibrated and adjusted and its channels must be aligned in time. In addition, essential characteristics must be monitored to guarantee a good working condition of the apparatus (to avoid loss of efficie

The majority of microarray studies evaluate gene ex- pression differences between various specimens or con- ditions. However, the causes of this variability often re- main unknown. Our aim is to identify underlying causes of these patterns, a process that would eventually enable a mechanistic understanding of the deregulation of gene expression in cancer. The procedure consists of three phases: pr

Pre-experimental familiarity can have paradoxical effects on episodic memory. Knowledge of the stimulus domain usually enhances memory, but word frequency - a presumed correlate of prior experience - is negatively related to recognition accuracy. The present study examined episodic recognition of names and its relation to two measures of pre-experimental knowledge, name frequency, and fame. Freque

This paper presents theory and algorithms for covariance analysis and stochastic realization without any minimality condition imposed. Also without any minimality conditions, we show that several properties of covariance factorization and positive realness hold. The results are significant for validation in system identification of state-space models from finite input-output sequences. Using the R

Two methods for estimating the sensor offset of a cylinder pressure transducer are developed. Both methods fit the pressure data during pre-combustion compression to a polytropic curve. The first method assumes a known polytropic exponent, and the other estimates the polytropic exponent. The first method results in a linear least-squares problem, and the second method results in a nonlinear least-

Book abstract: The book reviews recent observations of non-evolved and evolved binary populations in clusters and the field with special emphasis on statistical biases, incompleteness and distribution functions. Different binary types are considered: cataclysmic variables, super-soft X-ray sources, double degenerate binaries, Algol-type binaries, Be binaries, X-ray binaries, and Wolf-Rayet binarie

538 vocalisations from three domestic cats were collected and used in a phonetic pilot study in order to test some recording and anal- ysis methods normally used with human speech. Based on auditive analysis, the vocalisations were categorised into five types and analysed for duration and F0. The most common type was a combined murmur and miaow. Similar mean type durations were found in all three

Abstract in Undeterminedhis paper focuses on the experimental evaluation and design of a magnetic core of a modular segment for a synchronous machine with a laminated wave-winding. The advantageous features of laminated windings, which are the simple production and the high winding fill factor with a good net shape, are optimized towards high torque capability. The focus in this study lies on the

What does love have to do with gaming? As games have grown in complexity, they have increasingly included narratives that seek to engage players with love in a variety of ways. While media attention often focuses on violent emotions and behavior in gaming, love has always been central to the experience. We love to play games, we have titles that we love, and sometimes we love too much or love terr

This paper attempts to address the failings of a predominant paradigm in IS research and practice that emphasises technological determinism. This paradigm makes use of a false belief in the power of rationality in organizational decision-making, and a mythology in which organizational actors can be viewed as passive ‘users’ of technology. We wish to create a discussion of the nature and role of pr

Control systems design has traditionally been treated separately from the design of its software and hardware implementation. The increasing use of embedded control in for example distributed, safety critical and mass-produced systems has caused an increasing need for the simultaneous consideration of the control system and its implementation platform during development To this end, there is a nee

Speckle is an unwanted noise in ultrasound images, and appears as returning echoes are coherently summed over the transducer surface. In Doppler applications, the total power of the received spectrum varies in a manner similar to speckle. This paper investigates the correlation of continuous-wave (CW) Doppler signals obtained from simultaneously transmitted carrier frequencies, when a slowly flowi
