Deploying the new generation ”Internet Protocol” (IPv6) over 802.16-based wireless networks is facing an important challenge as the IEEE 802.16 standard is failing to support IPv6 functionalities. In fact, unlike the other 802 standards, the IEEE 802.16 is based on a point-tomultipoint (PMP) communication model, where no direct connection (at the MAC layer) is possible between two stations, all...

In this study, we describe an auto-calibration algorithm with fixed but unknown camera parameters. We have modified Triggs’ algorithm to incorporate known aspect ratio and skew values to make it applicable for small rotation around a single axis. The algorithm despite being a quadratic one is easy to solve. We have applied the algorithm to some artificial objects with known size and dimensions ...

Sen, Pathologist of the Sambhunath Pandit Hospital. I must admit that I have no first-hand acquaintance with the literature of auto-haemic therapy. At the same time, the subject appears to be an extraordinaril...

Binary codes can be used to speed up nearest neighbor search tasks in large scale data sets as they are efficient for both storage and retrieval. In this paper, we propose a robust auto-encoder model that preserves the geometric relationships of high-dimensional data sets in Hamming space. This is done by considering a noise-removing function in a region surrounding the manifold where the train...

Auto-encoder is a special kind of neural network based on reconstruction. De-noising auto-encoder (DAE) is an improved auto-encoder which is robust to the input by corrupting the original data first and then reconstructing the original input by minimizing the reconstruction error function. And contractive auto-encoder (CAE) is another kind of improved auto-encoder to learn robust feature by int...

The current work deals with the efficient physical design of patch antennas given the desired parameters like resonant frequency , feed point position , substrate thickness , relative permittivity , input impedance (= + ), and efficiency . Based loosely on the analogy of perception of the human brain, a neurocomputing network has been designed, consisting of two distinct phases, namely, the tra...

BACKGROUND Auto-positive end-expiratory pressure (auto-PEEP) may substantially increase the inspiratory effort during assisted mechanical ventilation. Purpose of this study was to assess whether the electrical activity of the diaphragm (EAdi) signal can be reliably used to estimate auto-PEEP in patients undergoing pressure support ventilation and neurally adjusted ventilatory assist (NAVA) and ...

BACKGROUND Off-line calculation of the pulse pressure variation (PPV(ref)) has repeatedly been shown to be a reliable predictor of fluid responsiveness in mechanically ventilated patients. This study was designed to assess the ability of two algorithms for automated calculation of PPV (PPV(auto)) (Intellivue MP 70) and stroke volume variation (SVV(auto)) (FloTrac/Vigileo) to predict fluid respo...

We consider the hyperbolic generalization of Burgers equation τ u tt − κu xx + A uu x + B u t + H u x = f (u). For some special combination of parameters we succeed to find the subset of exact solutions to this equation, where the auto-Bäcklund transformation u(x, t) = M (x, t)Exp(h(x, t)) + Q(x, t) Exp(h(x, t)) + 1 to classical Burgers equation is still valid. As an example the bi-soliton solu...
