Abstract:
Roller linear guides are key components in machine tool. The accuracy and efficiency of a machine toll are determined by the stiffness and friction torque of roller guide. This study proposes an improved design method for roller guide. The influences of the rollers profile on stiffness, stress distribution of roller linear guide are analyzed using finite element simulation. In this work, the design of the roller, slider, and the overall structure is modified. Moreover, experimental investigations on noise and sliding friction of roller linear guide are compared to validate the proposed design

Abstract:
In traditional studies of linear motion roller guide, the static stiffness is a main indicator to evaluate the mechanical behavior. However, the local contact profile between the roller and raceway surface, although very important to the precision maintenance, cannot be reflected in the measured value of static stiffness. In this article, a new indicator, named the real contact total length (RCTL), is proposed based on the Greenwood–Williamson model and the Hertz contact theory. In particular, an electric contact model is presented where the RCTL of linear motion roller guide without preload i

Abstract:
Two-dimensional device simulator of laser diodes has been introduced and its capability for a quantitative device design of 1.3-µm InGaAsP ridge-waveguide lasers has been shown. It has been quantitatively clarified that the current spreading in the cladding layer plays a key role in determining the threshold current. In addition, it is found that the nonradiative recombination exerts a significant influence not only on the threshold current but also on the carrier distribution in the active layer, that is, the lateral gain profile.

Abstract:
The lateral-mode behavior of a semiconductor-laser array is analyzed after including the effect of injected charge carriers on the active-layer dielectric constant. The wave equation is solved self-consistently and the lowest-threshold lateral mode is obtained by treating the whole array as one unit. The resulting mode profile incorporates the effects of gain guiding, carrier-induced index antiguiding, and built-in index guiding. The analysis is therefore applicable to gain-guided as well as index-guided arrays. Near and far fields for both kinds of array are obtained and compared with those o

Abstract Through the project we built a solid professional foundation beyond the Graduate Development Program, implemented competence assurance vetted through internal & external accreditation, provided a structured and transparent development route for professional staff, provided employees with more flexibility in career growth and strengthened Petroleum Development Oman's (PDO) professional in-house capabilities. In addition, we will be able to report on overall competency levels across PDO's functions to better determine focus areas for capability development. This paper presents how a

Abstract:
Intense laser beams of usual shape (gaussian profile and circular symmetry) carrying more than a critical power are known to break up into several self-focused spots when propagating through homogeneous Kerr type nonlinear media. This chaotic instability prevents all the previously envisaged applications of the intensity controlled refactive index changed exhibited by Kerr materials. When the nonlinear propagation is restricted to two dimensions, for example in a planar waveguide, it has been shown, some years ago that soliton effects induce stable self guided beams at suitable intensities.

Abstract:
A reduction of CO2 emissions of aero engines can only be achieved by a reduction in the fuel consumption. For turbofan engines a major key for this is an increase in the engine bypass ratio to enhance the propulsive efficiency. This leads to an increased mass flow in the bypass duct and hence higher contributions of the bypass duct system to the flow pressure losses and hence the engine fuel consumption. Additionally the turbofan core engine gets smaller in size and the overall diameter of the engine increases. This requires advanced engine mounting concepts, such as core mounted subsystems, w

Abstract:
Civil society organizations (CSOs) like yours often work with limited funds, time, and resources. There’s also a misperception that testing is expensive. We’d like to show you that this isn’t always the case. This guide presents some simple ways to test your messaging and campaigns to identify how to best achieve your desired results – all while preserving your resources. This guidebook is meant for advocacy, communications, research and programs teams. These can be officers, managers and directors working with nascent or even established CSOs, social enterprises and other non-profits. It is p

Abstract:
Background: Public behaviour and the new hostile threats • Civil contingencies planning and preparedness for hostile threats requires accurate and up to date knowledge about how the public might behave in relation to such incidents. Inaccurate understandings of public behaviour can lead to dangerous and counterproductive practices and policies. • There is consistent evidence across both hostile threats and other kinds of emergencies and disasters that significant numbers of those affected give each other support, cooperate, and otherwise interact socially within the incident itself. • In emerg
