The safety of powered two wheelers (PTWs) is an important concern for public authorities and road administrators. In France, even though road safety has improved since 2002, the number of accidents involving PTWs is still high. If we look at the figures, PTWs represent only 1% of the traffic but 28% of the deaths on the road. This shows that the risk of getting killed on a motorbike is 24 times greater than in a car. Over the past few years, there has been a significant rise in the number of PTWs, but there is still a lack of information on this class of vehicle. It is, therefore, difficult to study the interactions of PTWs with other road users and with the road infrastructure. The state-of-the-art study conducted in 2009 showed that there is no technical solution as such that can be adapted to measure this category of vehicle in traffic (unlike cars and trucks), so research in this domain has not greatly advanced, which is an issue of concern. In this paper we propose using a rangefinder to detect PTWs in traffic, a new method that shows promising results.

Adaptive filter is a primary method to filter ECG signal, because it does not need the signal statistical characteristics. In this paper we present a novel adaptive filter for removing the artifacts from ECG signals based on Constrained Stability Least Mean Square (CSLMS) algorithm. This algorithm is derived based on the minimization of the squared Euclidean norm of the difference weight vector under a stability constraint defined over the posteriori estimation error. The adaptive filter essentially minimizes the mean-squared error between a primary input, which is the noisy ECG, and a reference input, which is either noise that is correlated in some way with the noise in the primary input or a signal that is correlated only with ECG in the primary input. Different filter structures are presented to eliminate the diverse forms of noise. Finally, we have applied this algorithm on ECG signals from the MIT-BIH data base and compared its performance with the conventional LMS algorithm. The results show that the performance of the CSLMS based algorithm is superior to that of the LMS based algorithm in noise reduction.

A compact CPW-fed planar monopole antenna for ultra-wideband applications is presented and investigated. The proposed antenna with a small size of 20 mm ×26 mm × 1.6 mm is composed of a staircase shaped radiating element fed by a CPW feed line, and an inverted stair-style ground. The measured results agree reasonably with the simulated ones. The proposed antenna yields a wide bandwidth ranging from 3.1 to 11.4 GHz with return loss less than −10 dB with monopole like radiation pattern and stable antenna gain

With its vast unlicensed spectrum of 5 GHz and data speed of up to 2.5 GHz, 60 GHz is envisaged for short range communication in indoor environments. It is driven by the demand for broadband wireless applications such as IPTV, high definition television (HDTV), even uncompressed video. However, in such networks, handoffs are performed frequently due to the small cell (due to smaller range) and the time available for completing a handoff process is short. In order to make a successful handoff, predicting the next location of the mobile user is an important step. It can also enable the system to adapt resources and improve the Quality of Service. In indoor environment, people tend to repeat their movements and also have their selected places, such as offices, libraries, etc., and thus have daily movement patterns. Thus, the system can find their habits from the past. To exploit such patterns, this paper proposes a method using Hidden Markov Model as a learning technique to predict next location of the user. For particular data sets, our experimental results show that the prediction accuracy is up to 81.4% for regular employees and 54.6% for a guest.

This paper presents the optimization of length of an optical fiber grating for maximum reflectivity and minimum side lobe strength. The performance of fiber Bragg grating mainly depends on grating length and change in refractive index. Change in refractive index plays a crucial role in side lobe strength; it increases with increase in change in refractive index. It is mainly due to abrupt change in refractive index at the two edges of the grating. The wavelength chosen for analysis is from the third window to minimize the attenuation. The reflection spectra with different lengths and change in refractive index were analyzed. The simulations are based on solving coupled mode equations by transfer matrix method and the optimized parameters are obtained.

This paper presents an approach for calculating coupling efficiency in a holey fiber holographic coupler system. There are two main contributions of this work. First, the current work is an attempt to analyze the coupling efficiency between two holey fibers for the first time using a holographic coupler. Second, our numerical analysis provides some insight for optimizing the coupling efficiency between two holey fibers by changing the relative hole size, diameter of the core of the fiber. Further our results are found to be in good agreement with results of coupling efficiency due to splicing in literature qualitatively.

Wireless backhaul systems have been considered as a promising candidate of beyond 3G wireless broadband system for mobile communications. The achievable transmission performance over radio relay channel depends on antenna directivity and radiation patterns of each antenna element. To improve the transmission performance and keep radio relay channel in an acceptable condition, it is effective to control the antenna directivity by employing multi-antenna signal transmission and reception. In this paper, we propose a simple method to extend the existing single antenna relay node based on IEEE802.11a to multi-antenna system, where a cross polarized multi-antenna is applied to the existing relay nodes as external equipment. The multi-antenna system is controlled by detecting the antenna control information assigned to the lengths of the packets transmitted from the existing node. The proposed method does not require special change of the existing system such as hardware design on multi-antenna configuration. We also developed a prototype base/relay node with optional multi-antenna equipment and confirmed the effectiveness of the proposed method by experiment. To clarify the effectiveness of the proposed multi-antenna system in wireless backhaul networks, we evaluate throughput performance by system level simulations. Simulation results ensure that the proposed multi-antenna system with highly efficient packet forwarding protocol, called Intermittent Periodic Transmit (IPT), improves throughput performance of the radio relay transmission in wireless backhaul as compared with conventional omni-directional antenna system.

In this paper we present a system which automatically generates a 3D face model from a single frontal image of a face with the help of generic 3D model. Our system consists of three components. The first component detects the features like eyes, mouth, eyebrow and contour of face. After detecting features the second component automatically adapts the generic 3d model into face specific 3D model using geometric transformations. Our system allows the rotation and zooming of 3D model and generation of texture. Animation is produced using 3D shape morphing between the corresponding face models and blending the corresponding textures. Our system has the advantage that it is fully automatic, robust and fast. It can be used in a variety of applications for which the accuracy of depths are not critical such as games, avatars, face recognition etc. We have tested and evaluated our system using database BU-3DFE.

This work describes a 9bit 200MSPS 0.18µm CMOS process four-stage parallel pipeline ADC with 2.5 bit per stage. Primary objective of the design has been to make a trade-off between power consumption and resolution while keeping the sampling rate high. The parallel-pipeline architecture was best fit for such requirements. A new sub-ADC scheme has been introduced here to remove possible switch generated charge injection error in order to maintain good overall accuracy. The designed ADC in this paper employs parallel architecture based on double sampling sample hold topology (DSSH) and shares the OTA between the same stages of two channels of the ADC. The ADC achieves 55.5dB SNDR and 41.3dB SFDR with 29.5mW power consumption from 1.8 V supply. The resulting FOM is 0.304 PJ/conversion step. The high speed specification of the system requires the design of low offset comparator.
