Temporal Paul wavelet analysis for instantaneous phase extraction using shadow moiré technique is proposed. Unlike the Morlet wavelet, the Paul wavelet has less restriction on the adjustment of wavelet parameters and can provide an optimal time and frequency resolution for a particular application by selecting the proper parameters. The Paul wavelet is a complex wavelet and is suitable for processing the temporal intensity data obtained from the shadow moiré technique for the phase retrieval. The proposed method can extract the phase information related to the state of the dynamic object at every instant in temporal domain. The phase information is associated to the displacement, three-dimensional(3D) surface-profile and the instantaneous state of the dynamic object. In addition, the instantaneous frequency of vibrating object can be obtained using the scale of the wavelet ridge by direct integration without temporal and spatial phase unwrapping. Thus the phase unwrapping error can be avoided. An experiment is conducted on the central loaded beam to demonstrate the validity of the proposed technique. 3, record 5, English, - shadow%20moir%C3%A9%20technique

The term “moiré” is ... a French word referring to “an irregular wavy finish usually produced on a fabric by pressing between engraved rollers” (Webster’s 1981). In optics it refers to a beat pattern produced between two gratings of approximately equal spacing. It can be seen in everyday things such as the overlapping of two window screens, the rescreening of a half-tone picture, or with a striped shirt seen on television. The use of moiré for reduced sensitivity testing was introduced by Lord Rayleigh in 1874. Lord Rayleigh looked at the moiré between two identical gratings to determine their quality even though each individual grating could not be resolved under a microscope. ... Since Lord Rayleigh first noticed the phenomena of moiré fringes, moiré techniques have been used for a number of testing applications. Righi (1887) first noticed that the relative displacement of two gratings could be determined by observing the movement of the moiré fringes. The next significant advance in the use of moiré was presented by Weller and Shepherd (1948). They used moiré to measure the deformation of an object under applied stress by looking at the differences in a grating pattern before and after the applied stress. They were the first to use shadow moiré, where a grating is placed in front of a nonflat surface to determine the shape of the object behind it by using the shape of the moiré fringes. 4, record 5, English, - shadow%20moir%C3%A9%20technique

With the termination of SA [selective availability], ionospheric delay becomes the largest contributor to the GPS error budget(Shaw et al., 2000). As the ionosphere is a dispersive medium, it causes a delay to the GPS signal that is frequency dependent. Therefore, using a dual frequency receiver, we can combine the L1 and L2 measurements to generate the so-called ionosphere-free linear combination, which removes the ionospheric error. 4, record 9, English, - dual%2Dfrequency%20receiver

The learning theory of Thorndike represents the original S-R framework of behavioral psychology : Learning is the result of associations forming between stimuli and responses. Such associations or "habits" become strengthened or weakened by the nature and frequency of the S-R pairings. The paradigm for S-R theory was trial and error learning in which certain responses come to dominate others due to rewards. 3, record 10, English, - trial%20and%20error%20learning

The laser gyro need not be mechanically dithered. The same result may be achieved by optical devices. A Faraday cell is a piece of crystal, which changes the phase of a light wave traveling through it as a function of an applied magnetic field. The effect is nonreciprocal. A light beam traveling in one direction is advanced in phase, while a light beam traveling in the other direction is retarded in phase. Reversing the magnetic field reverses the effect. Changing the phase of the light beam has the same effect on frequency as changing the path length. This scheme eliminates the vibration problem, but retains the random walk angular position error. 2, record 12, English, - random%20walk

[...] si le rayon de Larmor de la particule est tel qu'il existe des valeurs de l'angle pour lesquelles la relation (3.16) est vérifiée, la particule subira alors une déflection qui fera varier son angle d'attaque, entraînant du même coup une déviation de sa trajectoire originelle. Le processus alors engagé amènera la particule à rencontrer d'autres résonances qui entraîneront alors une marche au hasard pour la particule. Cette marche au hasard est la base du processus diffusif qui veut qu'une particule perde rapidement le souvenir de sa trajectoire initiale. L'exemple présenté ici est évidemment simpliste (la relation 3.16 n'est pas [toujours valide]). Néanmoins, dans le cas des champs magnétiques chaotiques à trois dimensions, l'idée de résonance reste. Ainsi, il faudra que la particule suive une relation similaire à (3.16) pour qu'elle rencontre des résonances avec le chaos. Si le rayon de Larmor d'une particule est très inférieur (ou supérieur) à la plus petite longueur d'onde du champ chaotique, elle ne subira pas d'effets de diffusion spatiale ou angulaire. 3, record 12, French, - cheminement%20al%C3%A9atoire

La précision des centrales à inertie conditionne directement celle de la trajectoire du missile. En effet, la phase du vol pendant laquelle on peut guider le missile se limite à la phase propulsée, qui dure de 100 à 200 secondes, alors que la phase balistique (non propulsée), où le missile est soumis à la seule attraction terrestre, dure [...] de 1 000 à 2 000 secondes. Aujourd'hui, les limites technologiques des centrales inertielles de type pendulaire sont atteintes et il est envisagé d'utiliser d'autres types de capteurs pour améliorer la précision, tels que des accéléromètres à poutre vibrante. 2, record 13, French, - acc%C3%A9l%C3%A9rom%C3%A8tre%20%C3%A0%20lame%20vibrante

Il existe depuis une dizaine d'années de petits accéléromètres à coût acceptable. Il existe plusieurs grands principes : Muruta produit le Gyrostar, un prisme excité par piézo, utilisant la force de Coriolis qui donne trois vitesses angulaires. [...] Les autres fabricants utilisent des lames ou poutres vibrantes donnant des accélérations perpendiculaires aux plans de vibration. Un barreau vibrant lesté, est excité par un piézo, un deuxième piézo collé sur la face opposée de la lamelle recueille le signal de vibration. En cas d'accélération perpendiculaire au plan de la lame, la sinusoïde reçue est déformée, le mouvement étant accéléré dans le sens du déplacement, freiné dans l'autre. Les signaux excitation et réponse sont combinés dans un soustracteur, une manipulation donne un signal qui pilote un convertisseur à PWM (Pulse Width Modulation). Le rapport cyclique variable donne l'accélération. 3, record 13, French, - acc%C3%A9l%C3%A9rom%C3%A8tre%20%C3%A0%20lame%20vibrante
