background conservative surgical treatment has been the treatment of choice for early breast cancer. it allows feasible oncological treatment with a satisfactory cosmetic approach and fast recovery. however, in some cases mastectomy is necessary. this study proposes a surgical approach with only one surgical access through the same incision, which is in line with precepts mentioned above. it is...

The dual-airflow window could be used to conserve energy and improve indoor air quality in buildings because it works like a heat exchanger and can introduce outdoor air into buildings. In order to optimize the window design, this investigation used the orthogonal method to evaluate the importance of these 13 design parameters of the dual airflow window in energy conservation: outdoor air suppl...

In this paper, a new approach for optimizing disparity candidates space is proposed for the solution of dense stereo matching problem. The main objectives of this approachare the reduction of average number of disparity candidates per pixel with low computational cost and high assurance of retaining the correct answer. These can be realized due to the effective use of multiple radial windows, i...

This study investigated whether information retrieval can be improved if documents are divided into smaller subdocuments or passages, and the retrieval score for these passages are incorporated in the final retrieval score for the whole document. The documents were segmented by sliding a window of a certain size across the document. Each time the window stopped, it displayed/extracted a certain...

In this article, stream flow effectivness is based on hydraulic network studied in the shell-side of a shell and tube heat exchange as a case study. For an appropriate heat exchangers rating design to meet a specified duty, it's better to consider each stream flow separately. Using the hydraulic network principals, a set of the correlations for calculating different stream flow rates in the cro...

It is a demanding and time-consuming task to construct the side window mechanism of a car such that the deflections along the seals are minimized. The reason for this is that the window surface S delivered by the stylist, will in general not be movable in a proper way: It is required that the surface tightly moves along the seals. Deflections will necessarily occur no matter how much effort the...

Existing digital logic simulators typically depend on a discrete-time model of circuit behaviour. Whilst this approach is sufficient in many cases for the validation of the behaviour of synchronous circuits, it is not good at identifying glitches that are narrower than the available time resolution. Moreover, it is not generally feasible to accommodate uncertainty in delay time in such a way as...
