The purpose of the present paper is to obtain some subordination-and superordination-preserving properties for multivalent function associated the differintegral operators defined on the space of normalized analytic functions in the open unit disk. The sandwich type theorem for the integral operator is also considered.
Abstract This article describes the design of on‐chip bandpass filter (BPF) with split ring resonators (SRRs) for millimeter wave application. SRR is one of the metamaterial structures commonly used in designing the passive component and is used to improve the performance of the device. In this design, the BPF is desi…
The sole objective of casting procedure is to provide a metallic duplication of missing tooth structure, with as great accuracy as possible. The ability to produce well fitting castings require strict adherence to certain fundamentals. A study was undertaken to comparatively evaluate the effect on casting accuracy by…

In textile industry, besides the conventional textile products, technical textile goods, that have been brought external functional properties into, are being developed for technical textile industry. Especially these products produced with weaving technology are widely preferred in areas such as sports, geology, medi…
Abstract A Fabry–Perot (FP) cavity antenna simultaneously producing a high‐gain, wide‐bandwidth, and high front‐to‐back ratio (FBR) is proposed. To reduce the back radiation, we enclosed all the openings of our antenna with folded metal walls having a length of approximately 0.2λ at a center frequency of 1.8 GHz, and…
This paper addresses the frequency response, the identification of the resonance frequencies as well as the transient response of transformer windings taking into account all possible inter-turn mutual inductances and capacitances. The mutual inductances and capacitances between any turn to all other turns, i.e., not…
The ability of three chemical oxidants(Fenton’s reagent, Potassium permanganate and Potassium persulfate) to degrade one of the recalcitrant non-hydrocarbon components of crude oil- the porphyrins at three different pH media was investigated in this work and the results showed that the oxidants removed less than 10% o…
A series of different experimental techniques were applied to quantify the effects both steady and unsteady pressure differential across a fabric had on the flow through the fabric. Static permeability measurements were made on four common nylon parachute fabrics over a range of fix pressure differentials to provide a…
Abstract In this article, a novel architecture of the tunable capacitor is proposed for low‐voltage applications. In order to reduce operation voltage by enhancing fringing electric fields, two finger‐patterned electrodes with zero spacing are vertically separated by employing a multilayer thin‐film dielectric of a pa…
The amino acid sequences of soluble, ordered proteins with stable structures have evolved due to biological and physical requirements, thus distinguishing them from random sequences. Previous analyses have focused on extracting the features that frequently appear in protein substructures, such as α-helix and β-sheet,…
Abstract A simplified dual composite right/left‐handed (SD‐CRLH) transmission line (TL) structure is proposed and analyzed in this article.The SD‐CRLH TL with only capacitor in series is a left‐handed (LH) highpass filter, while the SD‐CRLH TL with only inductor in series is a right‐handed (RH) lowpass filter. By comb…
Electrospinning is a broadly used technology to obtain polymeric nanofibers ranging from several micrometers down to several hundred nanometers for a wide range of applications. It offers unique capabilities to produce nanofibers with controllable porous structure. With smaller pores and higher surface area than regul…
A key question in the theory of high-temperature superconductivity is whether off-diagonal long-range order can be induced wholly or in large part by repulsive electronic correlations. Electron pairs on cuprate and the iron-based pnictide and chalcogenide alternant lattices may interact with a strong short-range Coulo…
Physicochemical description of numerous cell processes is fundamentally based on the energy landscapes of protein molecules involved. Although the whole energy landscape is difficult to reconstruct, increased attention to particular targets has provided enough structures for mapping functionally important subspaces as…
Nanostructured polymer composites have opened up new perspectives for multi-functional materials. In particular, carbon nanotubes (CNTs) have the potential applications in order to improve mechanical and electrical performance in composites with aerospace application. This study focuses on the viscoelastic evaluation…
Different ZnO nanostructured films were electrochemically grown, using an aqueous solution based on ZnCl2, on three types of transparent conductive oxides grow on commercial ITO (In2O3:Sn)-covered glass substrates: (1) ZnO prepared by spin coating, (2) ZnO prepared by direct current magnetron sputtering, and (3) comme…
Abstract This letter presents a novel compact dual‐bandstop filter based on composite right/left handed transmission line (CRLH‐TL) resonator. By tuning the length of the shunted stubs in the CRLH‐TL resonator, each of the two stopbands can be controlled independently. The resonant properties of CRLH‐TL resonators are…
Abstract An isotropy terahertz (THz) metamaterial for dual‐band operation is designed and fabricated. The proposed metamaterial is composed of periodically arranged double metallic rings, and negative permittivity is obtained in 298–388 GHz and 652–780 GHz bands. Transmission and reflection characteristics of the prop…
The implementation and evaluation of a high fidelity material model for dry fabrics is the main objective of this paper. Inflatable Aerodynamic Decelerators (IADs) and other airinflated structures quite often utilize woven fabrics due to their lightweight and high loading carrying capabilities. Design optimization of…
