In this work, we first define intuitionistic fuzzy parameterized soft sets (intuitionistic FP-soft sets) and study some of their properties. We then introduce an adjustable approaches to intuitionistic FP-soft sets based decision making. Finally, we give a numerical example which shows that this method successfully works. © 2014 Elsevier B.V. All rights reserved. Source

In this paper, a novel solid phase supported Schiff base ligand (L 1: MDPMP) was prepared from 2-hydroxy-5-((2-methoxyphenyl)diazenyl) benzaldehyde (L: HMDB) and silica-gel, activated with 3- aminopropyltriethoxysilane (APTES). Cu (II), Co (II), Ni (II) and Mn (II) complexes of silica-supported ligand (L1: MDPMP) were obtained. The ligand and its four metal complexes were characterized by using NMR ( 1H and 13C), FT-MIR/FIR, elemental analysis, ICP-OES, TGA and Scanning Electron Microscope (SEM). Their catalytic performances in catalytic oxidation of cyclohexane were investigated for the selective oxidation of cyclohexane under microwave power. Silica-supported L1-Cu (II) complex was observed well selective catalytic properties for the oxidation of cyclohexane to cyclohexanol and cyclohexanone. © 2014 Elsevier B.V. All rights reserved.

Knowledge sharing barriers reduce the propensity of individuals to share knowledge and produce innovation behaviour. Thus, identifying barriers and their impact on knowledge sharing and individual innovation behaviour is a potential research area to study. Considering lack of studies in the literature, this study provides further evidence regarding the implications of knowledge sharing barriers in the workplace. Data was collected from eighty three academic staff in a higher education institution and analysed with Smart PLS. The results showed that organisation related knowledge sharing barriers are negatively related to knowledge collecting and knowledge donating. The result also indicates that individual knowledge sharing barriers have negative effect on individual innovation behaviours. There was no link found in this study between knowledge sharing and individual innovation behaviour. These findings provide empirical evidence to the further development of knowledge management and innovation research, and insights regarding how to better implement knowledge sharing and foster innovation behaviour in organisations.

This study numerically and experimentally introduces and investigates H-shaped metamaterials (MTMs) with negative refractive index on the coupling effect of a split ring resonator at the microwave X-band frequencies. The proposed models, consisting of one and two H-shaped MTMs structures, are designed in X-band for modern radar applications. The MTM structures show strong resonance at a range between 8 and 12 GHz. In addition, the effective constitutive parameters are revealed by using a retrieval procedure to verify the negative refraction phenomena of the proposed models. Furthermore, in order to verify the MTM characteristics of the structures, surface current distributions are realized. It can be seen that the structures can be efficiently used for filters, radar applications and so on in a certain frequency regime. © 2015 The Minerals, Metals & Materials Society Source

In this letter, a new group of elements of double and triple strips are proposed. Instead of a single perfectly conducting strip, a group of multiple strips constitutes a unit cell. In this case, the group is periodic, not the individual elements. The fraction of electromagnetic power reflected (reflectance) and transmitted (transmittance) of a new type of freestanding frequency selective surface (FSS), made of the group of elements per periodic cell, is examined theoretically for transverse magnetic (TM) polarization. The electric field integral equation (EFIE) technique with the subdomain overlapping piecewise sinusoidal (PWS) basis functions are employed to compute the unknown current coefficients induced on the metallic elements. It is observed that the spectral characteristic of single-strip FSS is enhanced by using periodic group cells. There exist transmission bands that allow full energy transfer for unequal lengths of double and triple strips. Double and triple resonances appeared in the event of unequal strip lengths. Since it is observed multiple resonances, the structure can be used in multiband antenna applications and subreflector systems. The computed results of strip FSS are compatible with the measured and calculated results in literature. © 2011 IEEE. Source
