The design of network elements for real-time control networks requires careful consideration of the fundamental timing requirements. The use of a timed automata approach for modelling and verifying the timing requirements promises to be beneficial. In this work a case study approach is shown where a model of the packet scheduler component for a network switch element is developed, based on a ti...

This paper presents a meshing algorithm for domains with internal boundaries. It is an extension of the gridding algorithm presented by Persson and Strang. The resulting triangulation matches all boundaries, and the triangles are all nearly equilateral. Equilateral triangles are beneficial for a finite volume discretization, as fluid flow between elements of very different size is only possible...

BACKGROUND Depression may induce malnutrition, but, as a paradoxical hypothesis, malnutrition may induce depression. This relationship, of course, depends on how we define malnutrition. CURRENT KNOWLEDGE Rubidium is a trace element strongly linked with depression, and is deficient in uremia sufferers. However, in uremic patients, rubidium deficiency is more evident during predialysis, as it i...

The worldwide demand for green energy systems is evident. In this context, wind energy converters will play a paramount role. Extending the service life of a wind energy converter translates into significant economic savings as well as ecological earnings. New opportunities for the management and operation of the wind energy converters make it beneficial to know the structural condition and the...

It is rare to find human populations exposed to a single malaria parasite species – in most endemic areas, at least three Plasmodium species co-exist. Here, we briefly review mixed species infection in malaria, and discuss apparently disparate clinical and epidemiological observations of Plasmodium falciparum and Plasmodium vivax, now equally prevalent in Thailand, which suggest that an ‘entent...

Boron is the fifth element in the periodic table of elements and has a number of important functions. The borate minerals have been known for thousands of years and have varied history from the deserts of Tibet to the alchemists of the middle ages. Boron occurs in most foods produced from plants. Since 1989 its nutritional value has been debated. Boron plays several biochemical roles in animals...

This paper evaluates an access selection architecture able to handle heterogeneous technologies. We establish a generic access selection algorithm, which assigns different weights to the constraints established by both the network and the terminal. In addition, we improve the traditional operation by allowing multi-hop extensions, by means of which an end-user may reach an Access Element (i.e. ...

Parkinson's disease is a degenerative of the nervous system. An important element in treatment neurorehabilitation. One forms neurorehabilitation may be biofeedback. The above technique uses electronic devices that allows an individual to learn how change body's function order reduce clinical symptoms and improve health. Previous studies have confirmed biofeedback has beneficial effect on healt...

The aim of this paper is to introduce a new family low-profile resonators and filters that achieve high performance low insertion loss without the need for post-production tuning. resonator termed ceramic-element based distributed consists matrix subwavelength-length ceramic posts connected in inter-digital fashion top bottom ground planes. Such disposition elements beneficial two main reasons....
