Abstract: An inset feed microstrip patch antenna is designed to increase the bandwidth and return loss. RT-Duriod with dielectric constant of 4.4 is used as a substrate for the proposed antenna. RT-Duriod is a having a lowest dielectric constant and can reduce the dielectric losses associated with microstrip patch antenna. This antenna is useful for 2.4 GHz frequency, which comes under ISM (Ind...

Communication Systems are being investigated for S, C, X and Ku bands. For portable systems, the size and cost of the antenna are of great importance. Microstrip antennas show promise due to their small and conformal features, and their ability to be mass manufactured. The bandwidth and return losses are also of great importance. A project is currently underway to examine the characteristics of...

Gene expression analysis is currently carried out using three methods that provide complementary data: microarrays, RNA-Seq, and RT-qPCR. Microarrays provide comprehensive whole-genome coverage in single experiments, with rapid data acquisition and results at a low price per sample. RNA-Seq provides the most comprehensive data across all RNA transcripts present in a sample. However, RNA-Seq als...

This paper describes a requirement of task skill in a service field, and a few task skill studies using our task skill transfer method. In a previous research, we have proposed a task skill transfer method using a bilateral teleoperation. In this method, it is assumed that a robot arm is implemented by the hybrid impedance/force control, and is able to execute a task by a suitable trajectory of...

In Central Aragón (NE Spain), where strong and dry winds are frequent all year round, fallow lands are susceptible to wind erosion due to insufficient crop residues on the surface and loose, finely divided soils by multiple tillage operations. Effects of conventional tillage (CT — mouldboard ploughing followed by a compacting roller) and reduced tillage (RT — chisel ploughing) on soil surface p...

AADL (Architectural Analysis and Design Language) is a textual and graphical language used to design and analyze software architecture of embedded real time systems. Many tools and models provide semantics and precise meaning for AADL architecture behavior. However, they are not supported by a well defined formal semantics. This paper suggets Rewriting Logic via its practical language Maude as ...

Environmental matrices are highly diverse in their composition and range from simple (e.g. water) to highly complex (e.g. organic soils/biosolids). Analysis of microbial gene expression from such substrates is done for variety of purposes which could range from bio-surveillance to elucidation of biological function of a target microbe. Quantitative real-time PCR (RT-qPCR) has become a technique...

An architecture for a Real-Time Volume Rendering Engine (RT-VRE) is given, capable of computing 750 x 750 x 512 samples from a 3D dataset at a rate of 25 images per second. The RT-VRE uses for this purpose 64 dedicated rendering chips, cooperating with 16 RISC-processors. A plane interpolator circuit and a composition circuit, both capable to operate at very high speeds, have been designed for ...

A theoretical basis is established for relating the incidence of relatively 'high' and 'low' »ring-current« intensities (as encountered, for example, in the central rings of peropyrene (I) and perylene (II), respectively) to intuitive Valence-Bond ResonanceTheory (VB-RT) ideas about 'bond fixation'. In the present treatment, this aim is not achieved by devising a »ring-current« formalism that i...

OBJECTIVE To report an unusual combination of paraglenoid labral cyst and labral tear with chondral defect of the humeral head. CLINICAL PRESENTATION AND INTERVENTION A 34-year-old man presented with right shoulder pain. Conventional MR imaging showed paraglenoid labral cyst. MR arthrography revealed a humeral chondral defect and labral tear associated with paraglenoid labral cyst, and a defe...
