Diffusive transport is characterized by the scaling law (length)^{2}∝(time). In this paper we show that this relationship is significantly altered in curved analog spacetimes. This circumstance provides an opportunity to tailor diffusion: by a suitable design of the analog metric, it is possible to create materials where diffusion is either faster or slower than in normal media, as desired. Thi...

The topic of this communication is contentbased retrieval of 3D objects represented as triangle meshes in the framework of MPEG-7. The idea consists of the use of suitable descriptors, which capture 3D shape. The descriptors are invariant with respect to translation, rotation, scaling, and reflections and robust with respect to level-of-detail. The presented analysis of 3D mesh models possesses...

High-performance processors are becoming increasingly power bound with technology scaling. Dynamic voltage and frequency scaling (DVFS) has emerged as an efficient method of reducing power consumption by lowering the operating voltage and frequency of a processor. We propose a multicore memory-aware DVFS scheme based on VSV, a uniprocessor DVFS algorithm that throttles a core based on L2 cache ...

abstract     the major constraints of agricultural production in the south western coastal areas of bangladesh are soil and water salinity of varying degrees, lack of fresh water for irrigation, slow soil drying pattern which are being augmented further due to climate change, requires suitable options of farming systems and component technologies. the major constraints and potentials of agricul...

an 8-year old boy with polyarthritis and nail involvement is presented in this report. nail involvement in reiter's syndrome is a rare condition that may include painless erythematous nduration of the base of the nail fold; subungual parakeratotic scaling and thickening opacification, ridging of the nail plate.

Hybrid fiber reinforced concrete (HFRC) consisting of two or more different types of fibers has been widely investigated because of its superior mechanical properties. In the present study, the effect of the addition of steel (0.25%, 0.5%, 0.75%, and 1% of concrete volume) and Polypropylene (0.2%, 0.4%, and 0.6% of concrete volume) fibers on the surface scaling resistance of concrete, depth of ...

In many applications that require physical interaction with humans or other physical environments, passivity is a useful property to have in order to improve safety and ease of use. Many mechatronic applications (e.g. teleoperators, robots that interact with humans) fall into this category. In this paper, we develop an approach to design passifying control laws for mechatronic components from a...

introduction:  the  advent  of  dual-modality  pet/ct  scanners  has  revolutionized  clinical  oncology  by  improving lesion localization and facilitating treatment planning for radiotherapy. in addition, the use of  ct images for ct-based attenuation correction (ctac) decreases the overall scanning time and creates  a noise-free  attenuation  map  (6map).  ctac  methods  include  scaling,  s...

Treatment and disposal of waste radioactive ion exchange resins is one of the most urgent problems for nuclear industries in China. Cement solidification technology has many advantages, such as requiring simple equipment, easy scaling-up, low working temperature, no trouble of gas cleaning and low cost. It is a suitable technology for treatment of waste radioactive resins, and has been widely u...

Miniaturization of microelectromechanical systems (MEMS) based devices can be achieved by flip chip assembly directly onto a flexible circuit substrate. The main goal of this work was the selection of a suitable bonding material and process to enable scaling down of MEMS sensorized devices for biomedical applications. Finally, the heat bondable anisotropic conductive film 5552R (3M) allowed mec...
