Abstract:
We use the fixed beam moving stage (FBMS) electron beam lithography technique to pattern a 10 mm long slot waveguide with s-bend tapered double-tip couplers. The fabrication method solves two major limitations of the FBMS mode, namely, the requirement for fixed-width structures and the incidence of stage placement drift for patterns involving elements of different widths. This has been achieved by fracturing the outline of the structure into fixed-width elements of gradually increasing width and creating intermediate overlap areas between the elements to mitigate the stage placement drifts.

This paper deals with a robust RFSID (Radio Frequency Self IDentification) system for road-to-car communications. The RFSID-based system operates in Ku-band and consists of a fixed transmitter, located at the road side, and of a receiver unit placed on the moving target, i.e. a car in its first proposed application. A slotted waveguide antenna array is used to illuminate the moving object at the desired position, whereas a four-patch array antenna is adopted at the receiver side. Both the antennas have been designed using numerical simulations based on a Finite Difference Time Domain (FDTD) al

This paper studies the dynamic response of a cantilevered beam subjected to a moving moment and torque, and combination of them with a moving force. The moving loads are considered to traverse along the length of the beam either from fixed-to-free end or free-to-fixed end. The beam is considered to have constant material and geometric properties. The beam is modeled using the Rayleigh beam theory considering the rotary inertia effects. The Dirac-delta function used to model the moving loads in the governing partial differential equations (PDEs) has complicated the solution of the problem. The

The effect of bridge vibrationinduced bylive loads such as vehicles and pedestrians is an important factor of bridge fatigue damage. It takes much labor and material resource to perform vibration experiments on bridges subjected by real moving loads in field. In order to carry out laboratory experiments on bridges subjected by moving loads, a fixed load with harmonic vibration simulates a moving load on bridge in the beam theory. A simply supported bridge is considered in the present study. The dynamic responses of bridge under different loads are established by the analytic method. Amplitude

In this paper, we are concerned with a cantilevered Timoshenko beam. The beam is viscoelastic and subject to a translational displacement. Consequently, the Timoshenko system is complemented by an ordinary differential equation describing the dynamic of the base to which the beam is attached to. We establish a control force capable of driving the system to the equilibrium state with a certain speed depending on the decay rate of the relaxation function.

Abstract:
Due to safety problems of modern structures continuously becoming more serious, structural health monitoring (SHM) systems are attracting increasing attention. The huge amounts of data being generated by SHM systems every day are challenging to analyze. Due to data-driven methods only considering the changes in signals, they are well-suited for this problem. This study considered an application of a data-driven method, moving principal component analysis (MPCA), for damage detection and location for moving-load quasi-static responses of a beam. The MPCA is an adaption version of principal component analysis (PCA) in which a fixed-length window is used to limit the data length so that it has some advantages in adapting to damage detection. Both finite element model and experimentation were used to prepare the time series for detection. It was noted that the MPCA algorithm showed good performances on both numerical and experimental data.

Abstract:
Legal status of the underage parent comprises conflicting roles of a parent and a child in the same person. It triggers many legal issues primarily revolved around underage parents’ capability to exercise parental responsibility. Using their natural ability to bear the child, the underage parents actually step out of the boundaries of childhood moving into to world of adulthood despite of the fixed age limits accepted by the law in order to separate, somehow artificially, those two domains. Since life usually precedes the law, giving birth to a child by the underage parents creates a legal mess where the rights and interests of the various participants are at stake. However, the lawmakers are torn between two basic ideas to protect the rights of the newborn and to enable natural parents to acquire parental responsibility so they can perform their duties as parents. This has been shown to be quite complicated task involving the consideration of different concepts such as reproductive liberty, legal parenthood, active legal capacity and child’s rights. Those issues have been considered by the author having in mind the complex picture of child’s rights, comparative law and national substantive family law rules. The attention is also paid to the solutions proposed by the draftmakers of Serbian Civil Code which could be adopted in the near future.

Abstract:
This chapter distinguishes the audience’s role and perspective when attending a conventional concert/proscenium stage event and a site-specific performance. The primary difference is that, with site creation, both the experience and meaning of the piece are influenced by how the audience physically encounters the art, so you must decide early in your creative and production timeline how the audience will experience the physical site and where they will be situated in relation to the performers. Audience design is a key part of the performance concept. The chapter explains how staging the audience can support the work’s intention, emphasize the site’s physical properties, and create the best viewing sightlines for the performance and emphasizes that the physical selected site is the subject matter of the work. Therefore, the design of how an audience sees the site must be integrated into the fabric of the performance experience. A brief overview of different audience design models are described in detail: frontal or proscenium design; fixed place, pivoting audience; fixed audience, multiple views; mobile audience/promenade performance; self-directed promenade with unified conclusion; mobile audience in moving vehicles; extended promenade performances; and simultaneous performances. The chapter concludes with a discussion of ticketing and its impact on audience size and design.

Abstract:
This paper proposes a methodology to find the hyperparameter that minimizes the compliance of the topology using a univariate dynamic encoding algorithm for searches. The difficulty in topology optimization is that there are various parameters that affects the topology of the modeling design such as the size of the elements to be designed, skip level, Poissions’ ratio, volume fraction limit, penalization power, and filter size. In most studies, these parameters were fixed and topology optimization was performed until the compliance value (cost value) converged. However, the result of the final topology optimization changes according to the change of the value of the hyperparameter in the design stage, it is necessary to study the optimization according to the change of the hyperparameters. To solve this difficulty, this paper pro- poses the methodology for hyperparameter optimization using a univariate dynamic encoding algorithm for searches. The hyperparameters were optimized using the proposed method with three topology optimization problems (both 2D and 3D cantilever beam, and 3D wheel) to show the effectiveness of the proposed methodology.

Abstract:
The ability to visualise hidden structures in detail using 3-D volume data has become a valuable resource in medical imaging applications (Maintz &amp; Viergever, 1998). Importantly, the alignment of volumes enables the combination of different structural and functional information for diagnosis and planning purposes (Pluim, Maintz, &amp; Viergever, 2003). Transform optimisation, resampling, and similarity calculation form the basic stages of a registration process (Zitova &amp; Flusser, 2003): During transform optimisation, translation and rotation parameters which geometrically map points in the reference (fixed) image/volume to points in the sensed (moving) image/volume are estimated. Once estimated, pixel/voxel intensities which are mapped into nondiscrete coordinates are interpolated during the resampling stage. After resampling, a metric is used for similarity calculation in which the degree of likeness between corresponding volumes is evaluated (Tait &amp; Schaefer, 2008). Optimisation of the similarity measure is the goal of the registration process and is achieved by seeking the best transform. All possible transform parameters therefore define the search space. Due to the iterative nature of registration algorithms, similarity calculation represents a considerable performance bottleneck which limits the speed of time critical clinical applications.
