Abstract:
The traditional elevator can only achieve vertical transportation task in the elevator shaft and can not achieve horizontal movement, which leads to that the elevator can not achieve horizontal transportation tasks in buildings. In order to further improve convenience and comfort of elevator transport, the new structure and operation mode of elevator are studied in this paper. Firstly, two types of building are defined: continuous type and discrete type. Then, based on the classification of building type, the structure and operation mode of elevator with function of vertical and horizontal travel are studied. In order to realize the horizontal movement of elevator for continuous buildings, horizontal motion of whole elevator or horizontal motion of car alone can be adopted. For buildings of discrete type, the feasible scheme is to separately drive the car horizontally run to realize the horizontal travel of elevator. The innovation design of elevator will have some help in the design and study of new elevator.

Abstract:
Abstract The economics of biogas plants have an impact on the justification of the industrial unit. The conditions of high-yielding high-quality biogas production are estimated on the basis of laboratory fermentation studies. In designing the laboratory fermenters, working conditions must be modelled. However, the biggest problem with the biological model is its size, because the magnitude is less than in industrial applications and therefore extremely sensitive to environmental influences. During the design, an important aspect is that the periodic mixing of the raw material can be done in the reactors as in the industry. This article shows the equipment based on empirical research.

Abstract:
A key to better geometric design of highways is designing horizontal curves conforming to driver behaviour. The values of side friction factors in the point mass formula, used for the design of the minimum radius of a horizontal curve, are based on the upper threshold of driver comfort. In the current guidelines, these driver comfort levels were established in research work carried out back in the 1930s. Recently, it was found that faster drivers tend to accept higher comfort thresholds to maintain their speed and minimize speed reduction between curve and tangent. An experiment was designed at Carleton University to collect newer data on driver behaviour including speed and lateral acceleration. The results confirmed the need to revise the values of side friction demand especially for sharp curves. In addition, a model was developed to determine the side friction factor to be used in design or in consistency evaluation of horizontal curves on rural roads and ramps.

Abstract:
Research has shown that vehicles shift laterally in the traffic lane during their entry to (or exit from) a horizontal curve. In addition, research indicates that most drivers momentarily adopt a path radius that is sharper than that of the roadway curve. A study was undertaken to investigate the causes of lateral shift and sharp path radii and to determine if they can be minimized (or eliminated) by modifying the horizontal curve transition design. From a review of the driver–vehicle control process, it was concluded that lane shift is due to unbalanced lateral accelerations that act on the vehicle as it enters the curve. These accelerations result from gravity, as effected through roadway superelevation, and side friction, caused by the steer angle of the vehicle. Kinematic models of lateral acceleration, velocity, and shift were developed. The calibrated models were used to develop design guidelines for superelevation rate and superelevation runoff location.

Abstract:
The objective of this paper is to provide analysis results of displacements and localized stresses in horizontal pressure vessels which were determined by using the three-dimensional finite element method. The analysis models utilized realistic geometry, including saddle supports, vessel heads and actual boundary conditions. The results give a detailed distribution of displacements and local stresses in the saddle support area, and show that the maximum stress is located at the horn of the saddle. A comparison of the results for different saddle locations, (A/L), was performed, and a reasonable location for the supports is suggested. Also, examples of parametric analyses and dimensionless design curves for calculating localized stresses are presented. The latter results should prove to be an invaluable aid in the generation of a new design code for horizontal vessels.

This paper presents a performance analysis of a horizontal axis wind turbine with an atypical design. The performance analysis was performed by a measurement in a low-speed wind tunnel. The atypical design of the horizontal axis wind turbine mimics the design of a radial turbine. The wind turbine was, however, simplified by “removing” the conventional stationary parts of the radial turbine, such as portion of the case or guide vanes. The paper describes the measurement test bed and compares the performance of this atypical wind turbine with more conventional designs.

Abstract:
This paper contains ground-motion prediction equations (GMPEs) for the vertical-to-horizontal spectral acceleration (V/H) ratio, and the methods for constructing vertical design spectra that are consistent with the probabilistic seismic hazard assessment results for the horizontal ground motion component. The GMPEs for V/H ratio consistent with the horizontal GMPE of Abrahamson and Silva (2008) are derived using the Pacific Earthquake Engineering Research Center's Next Generation of Ground-Motion Attenuation Models (PEER-NGA) database (Chiou et. al. 2008). The proposed V/H ratio GMPE is dependent on the earthquake magnitude and distance, consistent with previous models, but it differs from previous studies in that it accounts for the differences in the nonlinear site-response effects on the horizontal and vertical components. This difference in nonlinear effects results in large V/H ratios at short spectral periods for soil sites located close to large earthquakes. A method to develop vertical design spectra dependent on the horizontal component uniform hazard spectrum that accounts for the correlation between the variability of the horizontal ground-motion model and the variability of the V/H ratio ground-motion model is proposed.

Abstract:
Highway design consistency is one of the important criteria in selecting the geometric features of proposed or existing alignments of two-lane rural highways. Operating-speed (OS) profile models have been used to evaluate design consistency by trial and error. For a proposed new highway, however, there may be geometric and physical constraints, and selection of these elements by trial and error to achieve optimal design consistency would be difficult, if not impossible. This paper presents an optimization model that establishes highway horizontal alignment to achieve maximum design consistency based on the OS profile. The decision variables of the model include radius of horizontal curves, spiral curve lengths, length of speed-change (SC) segments, and acceleration and deceleration rates. The objective function of the model minimizes the mean OS difference or the maximum OS difference for successive geometric features along the highway section. Application examples and sensitivity analysis are presented to illustrate the capabilities of the model in evaluating improvement strategies and to ensure that the model produces sound optimum alignments. The proposed model, which complements existing optimization models that mainly address highway construction cost, should be of interest to highway practitioners and engineers.Key words: design consistency, highway, geometric, horizontal alignment, optimization modeling, speed profile.

Abstract. Flexibility and high production volumes are very important requirements in modern production lines. In most industrial processes, in order to reach high production volumes, the items are rarely stopped into a production line and all the machining processes are executed by synchronising the tools to the moving material web. "Flying saw" and "cross cutter" are techniques widely used in these contexts to increase productivity but usually they are studied from a control point of view. This work highlights the kinematic and dynamic synthesis of the general framework of a flying machining device with the emphasis on the driving system chosen and the design parameter definition, in order to guarantee the required performance in terms of flexibility and high production volumes. The paper develops and applies a flexibility oriented design to an horizontal wrapping machine.

Abstract:
This article describes a factorial experiment that is useful as a laboratory exercise in a research methods course. In the Howard–Dolman depth perception apparatus, two vertical rods are adjusted, using binocular or monocular vision, so they appear equidistant from the observer. The two rods can also be oriented horizontally, which allows a factorial design combining the factors of Viewing Condition (binocular and monocular) and Rod Orientation (vertical and horizontal). The exercise illustrates the nature of an interaction and the necessity of an additional analysis of simple main effects. It also provides a basis for understanding a perceptual problem in the real world—the difficulty of localizing horizontally extended stimuli such as power lines.

Abstract:
Revision of existing Yugoslav road-design standards, specifically in the area of road-design speed definition, required studying driver behavior in free-flow conditions in order to define drivers’ responses to the radii of horizontal curves. A specific approach with variable design speed for horizontal curves is discussed and is supported by speed measurements on roads. The pilot research was undertaken on several test sites on Yugoslav two-lane rural roads to collect reliable speed data related to characteristics of horizontal curves. Characteristics of test sites, experimental procedures, data collected, and results of data analyses are described. It is concluded that speeds of free-flow passenger cars show good correlation with radii and that actual design policy with a constant design speed underestimates speeds in radii less than 250 m. Thus, the variable design speed concept is a more realistic approach. Further research on more test sites is recommended.

Abstract:
In this paper, a design of FPGA-based 3D-TV horizontal parallax acquiring system is presented. The system will receive the stereoscopic video by a HD-SDI receiver GS2971, and outputs a video of horizontal parallax to a digital TV through a HDMI transmitter SiI9134. In this system, FPGA plays an important role that converts the stereoscopic video to the horizontal parallax video. In addition, a microcontroller is selected as the control center of the entire system. This system can get the horizontal parallax of the stereoscopic video in real time, and is helpful for the stereoscopic program producer to control the horizontal parallax of the 3D program.
