Researchers have proposed that during visual search, a color singleton cannot capture attention in a bottom-up fashion (Jonides & Yantis, 1988). In the present study, we manipulated the size of the attentional window by asking participants to detect either a global (diffuse attention) or a local (focused attention) shape before starting the search for a nonsingleton target. We demonstrate that ...

This paper proposes a novel adaptive filtering scheme to remove impulse noise from images. The scheme replaces the corrupted test pixel with the median value of non-corrupted neighboring pixels selected from a window dynamically. If the number of non-corrupted pixels in the selected window is not sufficient, a window of next higher size is chosen. Thus window size is automatically adapted based...

We study the throughput vs. window-size behavior of the sliding-window protocolon a trunked byte-stream virtual circuit where the node service discipline is processor sharing, background traffic is Poisson with exponentially distributed message lengths, propagation times are a significant fraction of the total delay, and the channel error rate is negligible. For small windows, the throughput is...

Modern microprocessors schedule instructions dynamically in order to exploit instruction level parallelism. It is necessary to increase instruction window size for improving instruction scheduling capability. However, it is di cult to increase the size without any serious impact on processor performance, since the instruction window is one of the dominant deciding processor cycle time. The reas...

BACKGROUND To explore the diagnostic method in assessing the malignancy of pulmonary adenocarcinoma characterized by ground glass opacities (GGO) on computed tomography (CT). METHODS Preoperative CT data for preinvasive and invasive lung adenocarcinomas were analyzed retrospectively. GGO lesions that were detected on lung windows but absent using the mediastinal window were subject to adjustm...

customer service level is of prime importance in today competitive world and has various dimensions with delivery quality being one of the most important ones. delivery quality has several parameters such as deliver time window options, time window size, etc. in this paper we focus on one of these parameters, namely time window setting. it has a direct impact upon customer satisfaction and busi...

In commercial buildings in Lahore, artificial cooling systems are needed to attain the required comfort level due to high heat gain inside. Energy efficient window design is the only solution which can limit this cooling demand. This simulated study is carried out in order to obtain a desirable window size (WWR). The study is carried out by the interpretation of graphical data which is generate...

The problem of fast running max/min lters for arbitrary-size windows is addressed. The size of the lter window is increased to the least power of two greater than the given size and the input sequence is expanded. The running max/min computation uses a fast algorithm for power of two window sizes, as described in 1]. The computational complexity (comparisons per sample) of the proposed algorith...

Traffic smoothing for delivery of online VBR media streams is one of the most important problems in designing multimedia systems. Given an available client buffer, a window size and a window-sliding size, previous window-based online smoothing methods try to reduce peak bandwidth allocated in each window. However, as bandwidths allocated in different windows are minimized independently, these m...

BACKGROUND We aimed to clarify that the size of the lung adenocarcinoma evaluated using mediastinal window on computed tomography is an important and useful modality for predicting invasiveness, lymph node metastasis and prognosis in small adenocarcinoma. METHODS We evaluated 176 patients with small lung adenocarcinomas (diameter, 1-3 cm) who underwent standard surgical resection. Tumours wer...
