The joining process of seam bond is used in automobile construction because of the non-visible joints on mounted parts such as doors, hoods or luggage compartment doors. With these components, a structure-providing inner panel is joined with the outer panel, which is visible to the customer. Besides providing stability, particularly in the event of a crash, the joining level is also filled with...

Abstract The industrial production of 3D printing is known as additive manufacturing (AM), in which a computer controls the process producing objects. Although x-ray computed radiography (XCT) extensively used quality control and testing products, gamma-ray capabilities for these applications still need to be investigated. This study aimed evaluate performance using americium-241 (Am-241) gamma...

This note is concerned with the stabilization of control systems using an estimated state feedback. The global stabilization problem for a relatively broad class of nonlinear plants is discussed. Moreover, using the “input to state stability” property introduced by Sontag [l-4] and detectability condition, we show that the system citn be globally asymptotically stable using a state detection. @...

A new method is proposed to check the detectability for a class of rectangular linear time invariant descriptor systems. The method is based on the properties of restricted system equivalent, derived here from a given descriptor system by means of simple matrix theory. Equivalence between the detectability of a given descriptor system and that of a normal system is established. The proposed res...

The relative detectability of three potentially optimal visual signals derived on the basis of statistical decision theory was measured and compared with that of a one-dimensional analog of the most detectable signal found by Watson et al. [Invest. Ophthalmol. Vis. Sci. Suppl. 20, 178 (1981)]. The latter signal was marginally easier to detect than the other three, but the small differences in d...

This study is part of a project to develop image discrimination models that can predict the detectability of target signals in color images. Image discrimination models take as input two images and predict the number of just-noticeable differences (JNDs) between the images. If one image is a background image and the other image has the identical background plus a target image, the model predict...

OBJECTIVE The aim of this study was to investigate the lesion detectability of a gamma camera based coincidence detector system (c-PET system) in comparison to the dedicated PET system (d-PET system), and thereby clarify the feasibility of the clinical application of this system and also describe any factors influencing the lesion detectability of the c-PET system. METHODS We examined 74 pati...

Advances in sensor and communication technologies have made it possible to manufacture small sensors with sensing, processing, and wireless communication capabilities in a costeffective fashion. A sensor network can be formed by deploying specialized sensors in the region of interest to perform certain sensing and networking tasks. Application scenarios of wireless sensor networks include battl...

If the spatial section of the universe is multiply connected, repeated images or patterns are expected to be detected observationally. However, due to the finite distance to the last scattering surface, such pattern repetitions could be unobservable. This raises the question of whether a given cosmic topology is detectable, depending on the values of the parameters of the cosmological model. We...
