attachment of children to their parents and their separation are two important growth processes which are summoned up in teens again and become more important. the present research tends to find out either the processes of attachment and separation among girls and boys take place in different ways or gender can affect the relationship between these two processes. to this end 300 students of the...

fracture of the proximal humerus associated with vascular injury has rarely been reported in children, and only two cases have been reported in the literature. in adults this combination has been reported more frequently. we present the case of a 14 year old boy with proximal humeral epiphyseal separation and axillary artery injury.

separation anxiety disorder (sad) is characterized by developmentally inappropriate and excessive anxiety concerning separation from home or those to whom the individual is attached. literature suggests that child attachment and anxiety symptoms are related. the aim of this study is to discover which symptoms of separation anxiety were associated with avoidant and/or ambivalent attachment. a to...

the separation of olefin/paraffin mixtures is an important process in petrochemical industries, which is traditionally performed by low temperature distillation with a high-energy consumption, or complex extractive distillationand adsorption techniques. membrane separation process is emerging as an alternative for traditional separation processes with respect to low energy and simple operation....

Separation Algebras serve as models of Separation Logics; Share Accounting allows reasoning about concurrent-read/exclusive-write resources in Separation Logic. In designing a Concurrent Separation Logic and in mechanizing proofs of its soundness, we found previous axiomatizations of separation algebras and previous systems of share accounting to be useful but imperfect. We adjust the axioms of...

Separation and localisation of P300 sources and their constituent subcomponents for both visual and audio stimulations is investigated in this paper. An effective constrained blind source separation (CBSS) algorithm is developed for this purpose. The algorithm is an extension of the Infomax BSS system for which a measure of distance between a carefully measured P300 and the estimated sources is...

We present a multiple antenna system for industrial, scientific, and medical (ISM)-band transmission (MASI). The hardware demonstrator was developed and realized at our institute. It enables multiple-input multiple-output (MIMO)-communication applications and is capable of transmiting arbitrary signals using 8 transmit and 8 receive antennas in parallel. It operates in the 2.4GHz ISM-band. The ...

We address the problem of blind source separation in the underdetermined mixture case. Two statistical tests are proposed to reduce the number of empirical parameters involved in standard sparsenessbased underdetermined blind source separation (UBSS) methods. The first test performs multisource selection of the suitable time-frequency points for source recovery and is full automatic. The second...

A class of methods based on multichannel linear prediction (MCLP) can achieve effective blind dereverberation of a source, when the source is observed with a microphone array. We propose an inventive use of MCLP as a pre-processing step for blind source separation with a microphone array. We show theoretically that, under certain assumptions, such pre-processing reduces the original blind rever...
