Road Engineering Technology Standard (JTG B01-2003) suggests that checking compu-tations of movement speed for designers in designing the speed changing roads,climbing lane,superelevation limited roads is necessary. The road geometrical constitutional parameters such as plane and horizontal and vertical curve radius,gradient,superelevation,widening,stopping sight distance and indicative road signs etc.,are main factors of influencing the movement speed of vehicle. In order to solve the problem of continuity of movement speed,first should solve the continuity of road alignment,that is to solve the combined problem of road geometrical elements.

In response to the imperfections of current sequence alignment methods, originated from the inherent serialism within their corresponding electrical systems, a few optical approaches for biological data comparison have been proposed recently. However, due to their low performance, raised from their inefficient coding scheme, this paper presents a novel all-optical high-throughput method for aligning DNA, RNA, and protein sequences, named HELIOS. The HELIOS method employs highly sophisticated operations to locate character matches, single or multiple mutations, and single or multiple indels within various biological sequences. On the other hand, the HELIOS optical architecture exploits high-speed processing and operational parallelism in optics, by adopting wavelength and polarization of optical beams. For evaluation, the functionality and accuracy of the HELIOS method are approved through behavioral and optical simulation studies, while its complexity and performance are estimated through analytical computation. The accuracy evaluations indicate that the HELIOS method achieves a precise pairwise alignment of two sequences, highly similar to those of Smith-Waterman, Needleman-Wunsch, BLAST, MUSCLE, ClustalW, ClustalΩ, T-Coffee, Kalign, and MAFFT. According to our performance evaluations, the HELIOS optical architecture outperforms all alternative electrical and optical algorithms in terms of processing time and memory requirement, relying on its highly sophisticated method and optical architecture. Moreover, the employed compact coding scheme highly escalates the number of input characters, and hence, it offers reduced time and space complexities, compared to the electrical and optical alternatives. It makes the HELIOS method and optical architecture highly applicable for biomedical applications.

It is an unfortunate fact that most wafer processing steps degrade the quality of the stepper alignment marks rather than improve it. One example is the severe planarization requirements used in many VLSI processes. Furthermore, process development time, especially with respect to wafer alignment, has been reduced due to fab streamlining and cost of ownership issues. With these problems in mind Nikon has developed a commercially available alignment simulator to reduce stepper usage in alignment process development. The simulator can simulate Nikon's three different wafer alignment sensor and has five different simulation modes. The simulated alignment mark can have up to ten different process layers, the thicknesses of which can be varied simultaneously if need be. In addition, the geometry of each process layer can be made quite intricate so that complicated processes can be simulate.d The simulator uses scalar diffraction theory for high speed calculations, but which is still accurate when the mark width is larger than optimization which previously took weeks can now be done in days.

Currently,the highway alignment design in China adopts designed speed theory.Designed speed is a constant value.However,long term practice shows that the actual running speed of vehicle always varies with the change of highway alignment.Therefore the designed speed theory itself has some limitations.It needs to use the dynamic running speed to verify highway alignment design for safety,so as to ensure driving safety.Based on the actual design practices,the Paper studies the running speed theory inspection method for highway alignment design.

This work shows that the alignment echoes induced in a gas by two laser pulses bring information on collision-induced changes of the rotational speed, revealing that collisions reduce the echo amplitude all the more efficiently when the echo appears late. This is explained by the filamentation of the rotational phase space induced by the first pulse and the narrowing of the filaments with time

In this thesis, rapid transfer alignment algorithm for a helicopter launched guided munition is studied. Transfer alignment is the process of initialization of a guided munition’s inertial navigation system with the aid of the carrier platform’s navigation system, which is generally done by comparing the navigation data of missile and carrier’s navigation data. In the literature, there are different studies of transfer alignment, especially for aircraft launched munitions. One important problem in transfer alignment is the attitude uncertainty of lever arm between munition’s and carrier’s navigation systems. In order to overcome this problem, most of the studies in the literature do not use carrier’s attitude data in the transfer alignment, only velocity data is used. In order to estimate attitude and related inertial sensor errors, specific maneuvers of carrier platform are required which can take 1-5 minutes. The purpose of this thesis is to compensate the errors arising from the dynamics of the Helicopter, lever arm, mechanical vibration effects and inertial sensor error amplification, thus designing a transfer alignment algorithm under real environment conditions. The algorithm design begins with observability analysis, which is not done for helicopter transfer alignment in literature. In order to make proper compensations, characterization and modeling of vibration and lever arm environment is done for the helicopter. Also, vibration based errors of MEMS based inertial sensors are experimentally shown. The developed transfer alignment algorithm is tested by simulated and experimental data.

This paper introduces a new High-speed Alignment Software adopting Servo-based approach. It builds on the External Guided Motion (EGM) interface of ABB robots. A novel framework for data fusion and servo is proposed with the emphasis on its improvement to traditional approaches and adaptability to sensors with low frame rate (around 10Hz). Auto spatial- and time-synchronization functions help user to deploy the software with less effort and expertise. This software can be applied in both static alignment application and target tracking (dynamic alignment) cases. Experiment results show that accuracy for static alignment can be improved by 50% and time consumption reduced by 70%. And error for dynamic alignment is still at the same level when sensor frame rate is reduced from 200Hz to 15Hz. The proposed solution can be applied in various applications including 3D gluing, fly-picking and other tasks requiring ultra-high precision.

The frame aligner is a key part in a digital multiplexer/demultiplexer system. A novel error tolerant frame alignment methodology is presented in this paper. Analysis shows that this method complies with ITU-T recommendation and improves the performance. The parameters of frame aligner and framing pattern are carefully selected. Finally, the parallel realization of a frame aligner with the proposed method, which can lower the working frequency and power, is applied in an STM-4 system.

This study deals with roadside survey of impaired drivers. 460 drivers who passed through the observation sites were stopped and breath-tested. These drivers were selected randomly from the traffic flow once an interviewer was available. BAC and speed/alignment data were obtained, the latter being measured by a pneumatic tube device. The device has two parallel pneumatic tubes perpendicular to the traffic flow for the measurement of speed and two tubes aligned in a V pattern for the measurement of lateral placement. 32 (7%) of the drivers were legally impaired (80 mg% or greater), 28 (6,1%) had a BAC between 50 and 70 mg% and 400 (86,9%) had a BAC less than 49 mg%.

<p>We recorded the number of correct and incorrect alignments stratified by reported mapping quality for each dataset. We then calculated the cumulative number of correct and incorrect alignments from high to low mapping quality. We considered an alignment correct only if the leftmost position was within 50 bp of the position assigned by the simulator on the same strand according to the previous study of Bowtie2 to avoid soft-clipping artifacts.</p>
