A modified ray approach isused to model the slot lens for determining V(z) and the results are compared with experiment for several materials. The slot lens is also used to obtain V(z) of ycut quartz for a number of slot orientations relative to the crystalline x axis. The Rayleigh wave velocity as a function of propagation direction is then deduced from these measurements and compared with acc...

We study the matching characteristics of a rectangular slot located in the farthest upper part of a ground plane. First, we investigate the effect of geometrical parameters including the length and width of the slot, the ground plane height, and feed point position on the input impedance. In turn, we consider the matching between the slot and a 50 feed and examine impedance-matched frequencies ...

In this paper, an efficient implementation of the spectral domain moment technique is presented for computing the self and mutual coupling between slot antennas on a dielectric half-space. It is demonstrated that by the proper selection of the weighting functions in the method of moments, the analytic evaluation or simplification of the transverse moment integrals is enabled. This results into ...

Automatic parking systems consist of three core technologies: target position designation, path planning, and path tracking. Target position designation methods can be divided into four categories: user interface-based, parking slot marking-based, free space-based, and infrastructure-based. Considering the fact that parking assist systems are expected to be used mainly in urban situations, reco...

The subject of this paper is the analysis of a discrete-time queueing model with infinite capacity, a single server serving exactly one packet per slot and with N input lines. On each of these input lines, there are messages arriving to the system that consist of exactly m packets. The important feature of this model however, is the fact that the packets of a message do not all enter the system...

We describe two tasks—named entity recognition (Task 1) and template slot filling (Task 2)—for clinical texts. The tasks leverage annotations from the ShARe corpus, which consists of clinical notes with annotated mentions disorders, along with their normalization to a medical terminology and eight additional attributes. The purpose of these tasks was to identify advances in clinical named entit...

This paper describes the system implemented by the NLP GROUP AT UNED for our first participation in the Knowledge Base Population at the Text Analysis Conference (TACKBP). For this Slot Filling Task, our approach was to design a distant supervised learning system, which was then specialized for the Regular Slot Filling and Full Temporal Slot Filling subtasks. From the initial Knowledge Base and...

We propose a new approach to developing a tractable affective dialogue model for general probabilistic frame-based dialogue systems. The dialogue model, based on the Partially Observable Markov Decision Process (POMDP) and the Dynamic Decision Network (DDN) techniques, is composed of two main parts, the slot level dialogue manager and the global dialogue manager. Our implemented dialogue manage...

Practical aspects of designing microstrip-slot couplers on an AI ~03 ceramic substrate (e, = 9.8) are treated in supplementation of the theoretical analysis of the coupler presented in Part I. Comparison with implemented couplers yields rules for specification of the reference planes at the ends of the coupling section and for the appropriate choice of definition for the slot-line characteristi...

We design, fabricate and experimentally demonstrate a highly efficient adiabatic mode converter for coupling light into a silicon slot waveguide with a slot width as large as 320 nm. This strip-to-slot mode converter is optimized to provide a measured insertion loss as low as 0.08 dB. Our mode converter provides 0.1 dB lower loss compared to a conventional V-shape mode converter. This mode conv...
