this paper showed the results of a qualitative investigation that looked into intracultural communication between brazilian teachers and students of english, and intercultural communication between american teachers and brazilian students of english. the aims were to identify and describe contextualization cues used by both brazilian and american speakers of english, and to connect these cues w...

this paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (uwb) wireless communication and target detection applications, respectively, operating in the frequency span of 3 ghz to 11 ghz. a prototype was fabricated and then measured based on optimal parameters. the results of reflection coefficient (s11) and radiation patt...

BACKGROUND Graphical probabilistic models have the ability to provide insights as to how clinical factors are conditionally related. These models can be used to help us understand factors influencing health care outcomes and resource utilization, and to estimate morbidity and clinical outcomes in trauma patient populations. STUDY DESIGN Thirty-two combat casualties with severe extremity injur...

according to leading authorities in the training system of islam, the reason for man's creation is the achievement of absolute perfection. given that on the one hand the wise creator must not have any impossibility in his purpose and the purpose from the wise must be possible and attainable and on the other hand man is a thinking creature and he never sets the impossible as his goal, the a...

We propose a multichannel residual cross-talk cancellation strategy to operate in environments where each microphone signal is dominated by one of several simultaneously active sound sources, like in a call-center scenario. The method relies on a two-step adaptive filtering scheme derived from an established GSC structure. The filter updates are performed in the frequency domain to allow an eff...

We propose a simple and straightforward way of creating powerful image representations via cross-dimensional weighting and aggregation of deep convolutional neural network layer outputs. We first present a generalized framework that encompasses a broad family of approaches and includes cross-dimensional pooling and weighting steps. We then propose specific non-parametric schemes for both spatia...

Computing over cross product rings has several advantages for VLSI signal processing [1]. These include the reduction of clock skew problems, natural fault tolerance [2], and ease of testing [3]. More traditional advantages include the promise of high speed arithmetic because of the removal of the carry, but the former advantages, we feel, are the most important. Although application areas are ...
