Transactions are contracts that guarantee a consistent, transparent, individual system state transition and their use is widespread in many different kinds of computing systems. Some well known standards (e.g. CORBA) include the specification of services that provide transactional properties. In this paper, we present a formal method for the systematic synthesis of transactional middleware base...

The preparation of a planar FeRh thin film using a focused ion beam (FIB) secondary electron microscope (SEM) for the purpose of in situ transmission electron microscopy (TEM) is presented. A custom SEM stub with 45° faces allows for the transfer and milling of the sample on a TEM heating chip, whilst Fresnel imaging within the TEM revealed the presence of the magnetic domain walls, confirming ...

We designed and constructed a novel, compact tri-band monopole antenna for intelligent devices. Multiband behavior was achieved by placing inverted-L shaped stubs of various lengths in triangular fed coplanar waveguide. The resonance frequency each band can be controlled varying the length corresponding stub. Three bands, at 2.4 (2.37–2.51), 3.5 (3.34–3.71), 5.5 (4.6–6.4) GHz, were easily obtai...

A planar compact bandstop filter (BSF) and a miniaturized resonator structure are presented along with its analytical equation to obtain resonance. The resonator is miniaturized by means of a shorted-stub which is loaded to a closed-loop resonator. Design and implementation of a 2.1 GHz BSF with 6% fractional bandwidth is presented.

In this paper an rectangular patch with parasitic stub whose edge have been cut , with two slots near the feedline has been proposed. The antenna is designed using HFSS software. The designed antenna shows wideband characteristics having simulated bandwidth of 96 %.The overall dimension of the antenna are 35×35×1.6 mm 3 .This antenna obtained maximum gain of 9.55dB having VSWR is less than 2. K...

• influences due to handling problems, distractions from environment or no unifying screen resolution. • participants might be used to TRA (a few trials of level 1 to 3 participants provide evidence) Future Work: • compare TRA layouts with layouts supporting 1/4SHPEDs [4] • with short “breaks" between serving graphs we may use the same graph in both models • investigate other stub sizes and mor...

Feature interaction (FI, in short) is a functional conflict among multiple telecommunication services, which is never expected from services in isolation. Detecting all possible FIs is an expensive and even infeasible task, due to the combinatorial explosion in the number of service combinations and scenarios. To reduce the cost of FI detection, FI filtering is known as a low-cost process condu...

Novel lumped dual-frequency impedance transformers (DFITs) for arbitrary frequency dependent complex loads (FDCLs) are synthesized using the concepts of capacitive and inductive inverters. Such a dual-frequency impedance transformer is constructed with one Pi-shaped lumped inverter and two shunt susceptance blocks at two sides, and get simplified after susceptance merging. The shunt susceptance...

Edge bundling is a technique to reduce clutter by routing parts of several edges along a shared path. In particular, it is used for visualization of geographic networks where vertices have fixed coordinates. Two main drawbacks of the common approach of bundling the interior of edges are that (i) tangents at endpoints deviate from the line connecting the two endpoints in an uncontrolled way and ...

We have studied the quantum transmission properties of serial stub and loop structures. Throughout we have considered free electron networks and the scattering arises solely due to the geometric nature of the problem. The band formation in these geometric structures is analyzed and compared with the conventional periodic potential scatterers. Some essential differences are pointed out. We show ...
