Radio access technologies (RATs) are a key topic in railways, enabling them better service rendering terms of shorter headways between trains, higher safety levels and customer satisfaction. Very often, these railway RATs need lot time to be developed, tested put into service, which implies lack efficiency bottlenecks the evolution systems. To solve this situation, an emulation platform that co...

A knowledge on the pullout forces of degradable craniomaxillofacial screws is essential in designing pediatric cranial implants. Herein, four non-identical commercially available composed different aliphatic polyesters were fixated to 3D-printed poly(l-lactide) screw hole test rig and onto a bone substitute material using manual tapping ultrasonic welding fixation techniques. method for mechani...

Digital filters have three components: (1) unit delays, (2) multipliers, and (3) adders. These components can be implemented by using (1) a Bragg cell as a tapped delay line, (2) optical multiplication using the Bragg cell transmittance, and (3) photodetectors. Multiplexing techniques are shown to increase geometrically the data handling capacity of such filters. An architecture for a 2-D digit...

Knowledge resources exist everywhere within organizations and communities. There is great hope that in addition to formalized and standardized resources that these collectivities regularly use (e.g., databases, standard operating procedures, and software processes), other knowledge resources can similarly be tapped. However, the expertise of an organization or the everyday communication flows a...

This article describes a flexible architecture for Real-Time Granular Synthesis that accommodates a number of Granular Synthesis variants including Tapped Delay Line, Stored Sample and Synthetic Grain Granular Synthesis in both Pitch Synchronous and Asynchronous forms. Three efficient algorithms for generating grain envelopes are reviewed and two methods for generating stochastic grain onset ti...

Simplified broadband beamformers can be constructed by sharing a single tapped-delay-line within a narrowband subarray. This paper discusses the use of fractional delay filters to a steering in the digital domain. For the narrowband subarrays, an optimisation approach is proposed to maintain an off-broadside look direction constraint as best as possible across a given frequency range. We demons...

was applied to his neck by a kabiraj, and during the next six weeks he tried various drugs without effect. At the end of two months he left his home and went to the Sambalpur hospital, where the swelling on his neck was thrice tapped by the Civil Surgeon. On each occasion a milkwhite fluid was drawn off, and rapidly accumulated again in the course of a few days. After a month at Sambulpur he ca...

It would be convenient if gigantic reservoirs of molecular hydrogen H2(g) existed in the earth’s crust that could be safely tapped as an energy source. Instead, most hydrogen found near the earth’s surface is bound up in water as protons, H(aq) that must be reduced before utilization as a fuel (1). When the electrons for proton reduction come from the oxidation of water to O2(g), this redox che...

Wideband CDMA systems with orthogonal spreading codes suffer severely due to the loss of orthogonality by multipath propagation. This yields Multiple Access Interference (MAI) which gravely reduces the performance of classical systems with Rake-receivers. In our approach we attempt to restore orthogonality again by using a fractional T-equalizer. The results are compared with a system using the...
