Forty years ago, Viterbi published upper bounds on both the first error event (burst error) and bit error probabilities for Viterbi decoding of convolutional codes. These bounds were derived using a signal flow chart technique for convolutional encoders. In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 convolutional enc

In the present work, surface thermometry using a method based on the spectroscopy of inorganic luminescent material was applied in the afterburner of a full-size aircraft jet engine. The technique uses laser-induced emission from thermographic phosphors for nonintrusive remote temperature diagnostics in combustion applications with high sensitivity and accuracy. A phosphor material having suitable

Various forms of supply chain management (SCM) research have been carried out in many different manufacturing or industrial settings over the last decades. However, less research exist concerning supply chain management in the service industry. Yet, definitions of supply chain management as they pertain to the service industry are only slightly different than those definitions of SCM in manufactur

Popular Abstract in Swedish Dagens samhälle är väldigt beroende av fordon av olika slag. Aldrig förr har människor rest till olika delar av världen, så mycket som idag. Den enorma mängden resors och transporter som sker varje dag är en tung belastning för vår natur. Bilar och lastbilar, som ökar i antal varje dag, släpper ut giftiga avgaser på vägarna och flygplan förbrukar enorma mängder fossilt Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. Today there are several solutions to meet the demand for better fuel economy

In today's competitive society the difference between winning and disappearing might very well be dependent on who is first to release a new product or an update to an existing product to the market. The impact that this situation has on the design analysis department in a company is tremendous. It is a known fact, to everyone working with design analysis, that the demands on analyses from the pro

The sequence of 15.7 kb from the human semenogelin gene locus has been determined. Together with previously published sequences, this gives the structure of a 28-kb region encompassing the two semenogelin genes. The two transcription units are separated by 11616 bp intergenic DNA comprising more than 40% repetitive DNA sequences, predominantly located to a 4-kb block of L1 and Alu repeats. Two mor

This study explores a novel approach to utilizing waste biomass for syngas production, with the potential for carbon sequestration. An integrated biomass conversion process combining pyrolysis, CO2 reforming, and MILD combustion is proposed. In the proposed system, the bio-oil obtained from pyrolysis can be used in a reforming step, converting it into syngas with a suitable H2/CO ratio for chemica

The maximum drawdown of a stochastic process is the largest peak-to-troughdecline observed over a given horizon [0, T]. Using arguments from extremevalue theory, we derive the limiting distribution of the maximum drawdown fora Brownian motion with positive drift as T → ∞. We show that, after suitablecentering and scaling, the maximum drawdown converges in distribution to theGumbel law.
