In this paper, firstly the time-constant of an integrator is described in continuous as well as in the discrete-time domains. Further, a simple relation is expressed to find the time-constant of an integrator from continuous-time domain to discrete-time domain or vice-versa. Thereafter, the microwave integrators of different time-constants are obtained by optimizing the characteristic impedance...

This paper presents a radio-frequency (RF) antenna as sensor to detect Horseradish peroxidase (HRP). At the core of proposed approach is graphene film deposited on stub connected an RF antenna. The doctor bladed stub. then properly chemically functionalized in order presence We validate proof-of-concept operation HRP concentration detection by measuring frequency shift reflection coefficient us...

1. Introduction Leaky-wave antennas based on an open-waveguide structure without partly physical cut become a candidate of millimeter-wave antennas because asymmetry of the structure can easily produce a radiation along its length due to a leaky mode. One of these open waveguides for antenna purposes is the stub-loaded ridge-rectangular waveguide, which consists of a ridge-rectangular waveguide...

Interconnection across administrative boundaries prompts the need for comprehensive policy enforcement (i.e., access control) with respect to inter-domain packet traac. Due to the nature of the communication services they provide, stub and transit domains require diierent mechanisms for policing inter-domain traac. This paper addresses the design of a policy enforcement mechanism geared speciic...

background:  the purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   methods:  this is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. the average time between implantation and removal was 23 month...

This paper introduces a design method of simple bandpass (BP) negative group delay (NGD) topology. The fundamental specifications BP NGD function are defined. passive topology consists parallel resistance associated with an open-ended microstrip stub. properties and characterization respect to the constituting stub parameters established. validations performed theoretical calculated simulated G...

In this paper we present Three-Valued Spatio-Temporal Logic (TSTL), which enriches the available spatio-temporal analysis of properties expressed in Signal Spatio-Temporal Logic (SSTL), to give further insight into the dynamic behaviour of systems. Our novel analysis starts from the estimation of satisfaction probabilities of given SSTL properties and allows the analysis of their temporal and s...

The Singwi, Sjölander, Tosi, Land (SSTL) approach is generalized to study the spin–correlation effects in a one dimensional electron gas. It is shown that the SSTL approach is capable of generating results comparable to the more widely used STLS approach. e-mail: [email protected] e-mail: [email protected]

The brain's sensory processing systems are modified during perceptual learning. To learn more about the spatial organization of learning-related modifications, we trained rats to utilize the sensory signal from a single intact whisker to carry out a behavioral task. Once a rat had mastered the task, we clipped its "trained" whisker and attached a "prosthetic" one to a different whisker stub. We...
