The first aim of the present study is to validate an extended technology acceptance model (TAME) on the data derived from the faculty members of a university in an ongoing, computer mediated work setting. The study extended the original TAM model by including an intrinsic motivation component — computer self efficacy. In so doing, the study asses

The use of lipase in hydrophilic solvent is usually hampered by inactivation. The solvent stability of a recombinant solvent stable lipase isolated from thermostable Bacillus sp. strain 42 (Lip 42), in DMSO and methanol were studied at different solvent-water compositions. The nzymatic activities were retained in up to45% v/v solvent compositions.

Vibration suppression is crucial for applications in engineering particularly for aircraft systems. A hybrid control approach comprising a feedforward intelligent command shaping technique inverse-model based PID feedback control is presented in this paper. The proposed augmented control scheme is used to control both the flexible motion and rigid

Artificial intelligence techniques, such as neural networks and fuzzy logic have shown promising results for modelling of nonlinear systems whilst traditional approaches are rather insufficient due to difficulty in modelling of highly nonlinear components in the system. A laboratory set-up that resembles the behaviour of a helicopter, namely twin r

Control of vibration suppressions is crucial for applications in engineering particularly in the area of aircraft system. A hybrid control approach encompasses of using a feedforward intelligent command shaping technique with combination of intelligent PID feedback control is presented in this paper. The advantage of using command shaping is to red

In the title compound, C20H21BrN2O2, the bromophenyl ring is twisted by 40.13 (8)� from the benzimidazole mean plane and the Br atom deviates by 0.753 (1) A ˚ from that plane. The sec-butyl group is disordered over two conformations in a 0.898 (5):0.102 (5) ratio. In the crystal, molecules related by translation along [110] are linked into chain

Magnetic materials are generally categorized into two categories, soft or hard. Soft magnetic materials are characterized by large permeability and very small coercivities while the hard one are frequently used in permanent magnet applications and are characterized by large saturation magnetizations and large coercivities. Soft and hard magnetic ma

Inductance is a property exhibited by a circuit element, called inductor. This property is a result of a changing magnetic field associated with a coil of given number of turns wounded on air core or core of some materials. Accordingly inductance depends on the geometrical dimensions, and the turns and the core used. Invariably the most important c

The on-going development in the field of sensors applications has opened up several possibilities for significant improvements in the advancement of bio-implantable devices or medical equipment. Some researchers have designed and developed inductive sensors for various applications such as tongues drive system enabling a person with severe disabili
