Introduction: The need to model and understand reactions among aqueous organic compounds and biomolecules has led to a number of experimental studies to determine the thermodynamic properties of these compounds. Unfortunately, there is a paucity of data for important compounds at elevated temperatures and pressures (including the current known temperature limits for biological activity, 122°C [...

The design procedure of a compact ultra-wideband (UWB) stepped impedance resonator (SIR) low pass filter (LPF), is presented in this paper. A SIR LPF with 15.5 GHz cutoff frequency miniaturized by meander line technique is designed and it is shown that offsetting the stepped impedance resonators, as well as indenting the tap location greatly improve rejection bandwidth. By cascading multiple fi...

Since publication of DSM-IV in 1994, the prevalence of parent-reported diagnosed attentiondeficit/hyperactivity disorder (ADHD) has tripled to more than 10% of children. Although it is hard to know for sure whether ADHD is overdiagnosed, underdiagnosed, or misdiagnosed, it is argued that ADHD is especially prone to diagnostic inflation and overdiagnosis. Therefore, we propose a model of stepped...

This work demonstrates a microwave dual band bandpass filter using two L–shaped stepped impedance resonators (SIRs) and a coupled feed structure. The coupled feed structure can be a single sided or a double sided structure. Two sets of physical parameters are used to control the coupling coefficient and external quality factor. Thus, the specification, such as the central frequencies and the ba...

A novel weighted l2,1 minimisation algorithm for a high range resolution profile with stepped frequency radar is proposed. The raw stepped frequency pulse train is converted into jointly sparse multiple measurement vectors by using the sliding window technique. Then, by using the Capon cepstrum a support-related weighting matrix is designed to control the priority class of bases in the reconstr...

This letter presents a wideband tri-passband filter in which tri-section stepped-impedance shunt-stubs are used as tri-mode resonators, connected by transmission lines. Developed from the topology of quarter-wavelength stub filters, these filters have much wider passbands compared to many other designs published. The stepped-impedance stubs also contribute transmission zeros between the passban...

A patient-specific, stepped approach to topical and intranasal analgesic pharmacotherapy was effective in reducing refractory postherpetic neuralgia (PHN) not responding to the current standard of care for PHN. The use of topical analgesic therapy allowed for higher concentrations of medication locally while reducing the likelihood of systemic side effects common to the drugs used. No adverse e...

An axially symmetric radial waveguide power divider, which utilizes a specific Cycloidal-Like tapered transition between central coaxial launcher and waveguide, is presented in this paper. In order to broad the operation band, change of impedance investigated, an analytic expression for shape obtained. A simple electromagnetic modeling stepped matching network developed, its characteristics are...

In recent years, research has been conducted on reducing resistance by adding steps the bottom of high-speed craft. The most significant issue in design multi-stepped planing craft is selection an appropriate step configuration, i.e., geometry, location, and height. This requires a general knowledge hydrodynamic behavior each configuration. Although towing tank test effective method to predict ...
