The heat flux on the divertor plate of a fusion reactor is probably one of the most limiting constraints on its lifetime. The current heat flux profile on the outer divertor plate of a device like the International Thermonuclear Experimental Reactor (ITER) is highly peaked with narrow profile. The peak heat flux can be as high as 30-40 MW/m 2 with full width at half maximum (FWHM) of the order ...

The influence of series elastic structures on the dynamics of the contractile machinery was examined in the gastrocnemius medialis (GM) of five male Wistar rats, with respect to enhancement of work of a muscle-tendon complex after active stretch. Imposed isotonic and isokinetic contractions were preceded by either an isometric phase (PI) or an active stretch (PS). The effects of fibre length di...

When analysing binary data, the ease at which one can interpret results is very important. Many existing methods, however, discover either models that are difficult to read, or return so many results interpretation becomes impossible. Here, we study a fully automated approach for mining easily interpretable models for binary data. We model data hierarchically with noisy tiles—rectangles with si...

This paper describes a Minimum Message Length (MML) approach to nding the most appropriate Hidden Markov Model (HMM) to describe a given sequence of observations. A MML estimate for the expected length of a two-part message stating a speci c HMM and the observations given this model is presented along with an e ective search strategy for nding the best number of states for the model. The inform...

Tracer testing has been used to obtain hydraulic properties in a reservoir system and may help characterize the fracture networks inside the reservoir. Numerous studies at various scales have shown that the distribution of many fracture properties (i.e., length, displacement) follows a power law scaling with some cutoffs. Fractal dimension is useful to evaluate the geometric characteristics of ...

The threshold voltage and current necessary for ventricular defibrillation was measured in dogs using capacitor-discharge and half-sinusoidal pulses of current of various durations. From these quantities the electrical strength required for defibrillation was determined and expressed as energy, peak current, and charge per gram of heart. The optimum current duration depends on the criterion sel...

fracture system in carbonate reservoirs is very complex. understanding the features of fractures such as dip, strike and the other parameters can help to distinguish the behaviour of reservoir in any exploration and production plan. image log is the best way to investigate feature planes like fracture and bedding. image log in one of drilled well #10x393 of bangestan reservoir in gachsaran oilf...

converting the organic wastes and losses into compost is an appropriate technique to stabilize organic materials. one of the limitative factors in transporting and storing the composts is their low specific mass which usually leads to increase costs in their processing. to overcome this limitation, several methods such as pelleting have been proposed especially for efficient processing of powde...

Anti-collision mechanisms in RFID, including current standards, are variations of Aloha and Frame Slotted Aloha (FSA). The identification process starts when the reader announces the length of a frame (in number of slots). Tags receive the information and randomly choose a slot in that cycle to transmit their identifier number. The best performance of FSA always requires working with the optimu...
