A new tool for studying the process of carbon nanotube chemical vapor deposition (CVD) synthesis is described. By rotating the substrate in situ during the CVD process, the orientation of floating nanotubes with respect to the substrate is changed by interaction with the gas stream. Nanotubes lying on the surface of the substrate, however, will maintain their relative orientation. As a result d...

In the study of PetaFlop project, Processor-In-Memory array was proposed to be a target architecture in achieving 10 floating point operations per second computing performance. However, one of the major obstacles to achieve the fast computing was interprocessor communications, which lengthen the total execution time of an application. A good data scheduling, consisting of finding initial data p...

The pagination problem of complex documents is in placing text and floating objects on pages in such a way that each object appears close to, but not before, its text reference. Current electronic formatting systems do not offer the pagination quality provided by human experts in traditional bookprinting. One reason is that a good placement of text and floating objects cannot be achieved in a s...

Fast Fourier Transform (FFT) processors employed with pipeline architecture consist of series of Processing Elements (PE) or Butterfly Units (BU). BU or PE of FFT performs multiplication and addition on complex numbers. This paper proposes a single BU to compute radix-2, 8 point FFT in the time domain as well as frequency domain by replacing a series of PEs. This BU comprises of fused floating ...

Eutrophic aquatic habitats are characterized by the proliferation of vegetation leading to a large standing biomass that upon decomposition may create hypoxic (low-oxygen) conditions. This is indeed the case in nutrient impacted estuaries of Prince Edward Island, Canada, where macroalgae, from the genus Ulva, form submerged ephemeral mats. Hydrological forces and gases released from photosynthe...

The purpose of writing this review on floating drug delivery systems (FDDS) was to compile the recent literature with special focus on the types of floating drug delivery systems, principal and mechanism of floatation to achieve gastric retention. Drug delivery systems are those that float immediately upon contact with gastric fluids present promising approaches for increasing the bioavailabili...

Nonlinear interactions among incident wave, tank-sloshing and freely floating body coupled motion are investigated. The fully nonlinear sloshing and body-surface nonlinear free surface hydrodynamics is simulated using a non-uniform rational B-spline higher-order panel method (NURBS) in time domain based on the potential theory. A robust and stable improved iterative procedure, iterative semi-im...

Floating matrix tablets of losartan potassium were developed with an aim to prolong its gastric residence time and increase the bioavailability of drug. Rapid gastrointestinal transit could result in incomplete drug release from the drug delivery system above the absorption zone leading to diminished efficacy of the administered dose. The tablets were prepared by wet granulation technique, usin...

Public transportation has been one of the most important research fields in the two last decades. The purpose of this paper is to create a schedule for public transport fleets such as buses and metro trains with the goal of minimizing the total transfer waiting time. We extend previous research works in the field of transit schedule with considering headways of each route as decision variables....

Embedded CPUs typically use much less power than desktop or server CPUs but provide limited or no support for floating-point arithmetic. Hybrid reconfigurable CPUs combine fixed and reconfigurable computing fabrics to balance better execution performance and power consumption. We show how a Stretch S6 hybrid reconfigurable CPU (S6) can be extended to natively support double precision floating-p...
