We show that the static force spectroscopy curve taken in an atomic force microscope is significantly modified due to presence of intrinsic cantilever instability which occurs as a result of its movement in a nonlinear force field. This instability acts in tandem with such instabilities as water bridge or molecular bond rupture and makes the static force spectroscopy curve (including 'jump-off-...

We report design and fabrication process of MEMS (Micro Electro Mechanical Systems) actuators for a new type of optical switch integrated with photonic crystal (PhC) waveguides. Thin film poly-silicon electrostatic microactuator (either a cantilever or a bridge style) is placed over a PhC waveguide to induce optical modulation by means of mechanical motion in the evanescent fields. For low volt...

a new design for replacing a missing anterior tooth is described. in this article, a lingually fixed partial denture, its advantages, disadvantages, indication and contraindications have been explained. the ability of this design to replace a single missing central or lateral incisor is discussed.

As a new construction method, the bridge horizontal rotation method can reduce impact of traffic under bridge. During bridge, overall structure will inevitably lead to vibration response due error contact surface spherical hinge. Due large weight and longer cantilever superstructure, at hinge be amplified girder end, which adversely affect stability structure. Taking 10,000-ton rotating as refe...

Segmental bridge construction is very common in Pakistan. However, the impact ofstructural system changes before and after completion of segmental achallenge major concern for stakeholders. Therefore, this study, stageanalysis was performed balanced cantilever technique to check safety andserviceability bridge. Through time dependent analysis, considering sequenceand creep deformation concrete,...

The resonant frequency and sensitivity of an atomic force microscope (AFM) cantilever with assembled cantilever probe (ACP) have been analyzed and a closed-form expression for the sensitivity of vibration modes has been obtained. The proposed ACP comprises an inclined cantilever and extension, and a tip located at the free end of the extension, which makes the AFM capable of topography at sidew...

The bridge of Shanghai Metro Line 10 over 6 is a U-shaped concrete single-box double-cell box beam continuous bridge. A novel method applied to construct the asymmetric cantilever prefabricated and assembled due limited construction space complex environment. Four mechanical state control methods are during T-shape structure process: tensioning pre-stressed steel strand, jacking by axial force ...
