Abstract:
There is a simple distributed optical fiber sensing system which is used to monitor vibration signal, having an additional sub-loop coupled with main ring by a 3dB coupler. This paper compares three outputting interfered beams, each of them traveling in the sub-ring 0, 1, 2 times separately. Using the simultaneous equations produced by those three outputs, it finds the relation between the interference lights and vibration signal's characteristics, such as frequency, amplitude and position. Through simplify and calculating, vibration position of long pipeline is to be achieved finally.Keywords:

In this paper, we describe an innovative method to form an ultralong ultralow loop for wire bonding. A resister was used to form kinks and simplify the capillary trace, which yielded a loop-like "n"-shape with two kinks immediately above the first and second bonds that can support the entire long-span loop. A 3-D finite element model was developed to simulate the n-loop formation, and the loop profiles of an n-loop, M-loop, and standard loop were compared. In this paper, we show that this novel n-loop can almost halve the looping time compared to that for the M-loop; and the n-loop can avoid wire sag for a 5000-μ m-long span. Furthermore, the loop height and wire verticality near the second bond can be modified by regulating the horizontal and vertical positions of the resister.

A loop (Q, ·) is called a Basarab loop if the identities: (x · yxρ) · (xz) = x· yz and (yx) · (xλz · x) = yz · x hold. A Basarab loop was shown to be a group if and only if it is a cross inverse property loop or its middle inner mapping is automorphic in action.Some algebraic properties of the left, right and middle inner mappings of a Basarab loop were explored. The algebraic properties of some bi-variate functions defined on a Basarab loop Q were established and these were used to explore the properties ofsome important mono-variate functions defined on Q. In addition, these bi-variate functions aided the establishment of fine-tuned necessary and sufficient conditions fora loop to be a left (right) Basarab loop, and Basarab loop in relations to left (right) CC-loop, and CC-loop, respectively. Some subloops of a Basarab loop were shown tobe characterized by the mono-variate functions. New characterizations of the centrum of a Basarab loop were obtained.

A natural extension of the loops we have used so far is a construction which has a loop within a loop, within a loop, and so on. This type of construction is referred to as nested loops, because each loop nests inside another loop. The terms outer loop and inner loop are used to describe a loop containing another loop, and a loop which is inside another loop, respectively. Program 7.1 shows a program with two loops.

This article discusses the relative advantages of a newly designed transfer loop which tends to obviate defects inherent in the traditional wire loop. Characteristics of the new transfer loop are discussed and compared to the traditional wire loop. The article discusses a series of transfers that were made to determine the range of inoculum delivered by the loops under both conditions of use: in the first series, twenty transfers were made with a commercial, prefabricated loop, submerging only the loop end and not its shank in the broth; in the second series, twenty transfers were made with the new stainless steel loop, submerging only the loop end and not its shank in the broth; and, in the third series, twenty transfers were made with the new stainless steel loop, inserting the loop to the bottom of the broth tube, and withdrawing it with the loop end held perpendicular to, and in contact with, the side of the tube. The loop was similarly inserted to the bottom of the distilled water tube to remove the entire amount carried by the loop.

Abstract Closing loops are used in orthodontics to apply forces on teeth and cause them to move in a desired direction. The objective of this study was to investigate the effect of loop geometry and position on loop properties. Using finite element analysis, loop response was simulated for three closing loop designs (vertical, T‐, and L‐loop) at thirteen loop positions. Loop length and height were 14 and 10‐mm, respectively. Loop properties (horizontal load/deflection, vertical force, and moment‐to‐force ratio M/F) on both ends were measured at 100 and 200 g force activation or when moving both ends 2‐mm together. It was found that the pattern of changes in loop properties with loop position was similar for the vertical and T‐loop. They reached their maximum M/F‐ratios of 5.5 and 7.3, respectively, at the ends closest to 1/5 or 4/5 off‐center loop positions. M/F‐direction at an end changed when the loop was about 2/3 away (vertical loop) or 4/5 (T‐loop). The L‐loop behaved differently, reaching its maximum 8.7 M/F‐ratio (200 g activation) when centered. M/F‐direction only changed at the opposite end of the L‐loop direction, and occurred when the loop was centered. This study showed that loop properties depended on loop shape, position and activation. The way properties changed with loop position depended on their designs. Clinicians should consider the specific characteristics of each loop configuration for desired tooth movements.
