A new technique called sequential window learning (SWL), for the construction of two-layer perceptrons with binary inputs is presented. It generates the number of hidden neurons together with the correct values for the weights, starting from any binary training set. The introduction of a new type of neuron, having a window-shaped activation function, considerably increases the convergence speed...

This paper studies TCP performance over multihop wireless networks that use the IEEE 802.11 protocol as the access method. Our analysis and simulations show that, given a specific network topology and flow patterns, there exists a TCP window size W , at which TCP achieves best throughput via improved spatial channel reuse. However, TCP does not operate around W , and typically grows its average...

This paper presents our basic approach to creating Proposition Bank, which involves adding a layer of semantic annotation to the Penn English TreeBank. Without attempting to confirm or disconfirm any particular semantic theory, our goal is to provide consistent argument labeling that will facilitate the automatic extraction of relational data. An argument such as the window in John broke the wi...

Transport layer and application layer of network stack use end-to-end adaptation protocols (e.g., TCP and bitrate-adaptive video) to achieve high performance by continuously adapting endpoint behavior to changes of network conditions. The traditional belief is that these protocols must be run independently by endpoints to achieve desirable performance. In essence, they use reactive logic trigge...

We studied the Rose Window instability phenomenon on a layer of low conducting liquid (e.g. oil) that is exposed under corona discharge. Most of the current researches focus on deducting qualitative descriptions of this phenomenon in fluid mechanical aspect, but lacks experiments and the study of micro mechanism of the forming of cellular structure. In this thesis, a series of verification expe...

window analysis is a known technique to evaluate performance during the time periods based on data envelopment analysis. in application of window analysis is assumed that efficient frontier have not changed during the periods in the study. unlike the window analysis, malmquist index tries to identify difference between efficient frontiers and separated them. but the means of different frontier ...

Abstract The epitaxial GaAs substrate lift-off (ELO) technique is widely used to produce thin film III–V semiconductor optoelectronic devices. However, the hydrofluoric (HF) acid in process forbids incorporation of active AlGaAs device layers with high Al content due its selective etching. In this work, a new ELO method presented, which allows for protection against HF attack. here prepare and ...

The AlGaInP window layers with different growth modes of Al in (AlxGa1−x)0.5In0.5P were prepared to investigate the effect on photoelectric properties red LEDs. experimental results show that forward voltage LEDs n-window layer ridge gradient content was 30 mV (x = 0.15) and 190 0.45), respectively, which are lower than without samples. Meanwhile, light output power LED is 12.3% 3.6% 0.45) high...

Objective(s): The energy resolution of a cadmium-zinc-telluride (CZT) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional Anger type detector which is 10%. Also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. In this study, we used a semiconductor detector and examined the ef...
