In this paper,instruction level optimization by exploiting SSE2 instructions is proposed to speed up the time-critical modules in H.264 ***2 instruction set to execute a large number of small-size native data type operations in parallel to improve the real-time multimedia data processing *** contributions of the paper are manifold:Firstly,the paper shows SSE2 instruction ***,we describe the complexity analysis and theory of H.264 key modules such as integer DCT, invert integer DCT and the sum of absolute transformed difference(SATD).Thirdly,the proposed approach is applied to H.264 video encoding and the experimental results show up to 13%speedup without degrading video quality,compared with results of the original encoder in H.264.

This paper mainly presented a research in which a GPRS-based environment monitoring system(GEMS) was developed to collect meteorological data influencing apple *** data collected are transmitted to a web server through GPRS service,and meanwhile replicated and stored in a SD card for avoiding the *** system has been deployed into 5 different main apple production regions in Yunnan province. Via two-year test,the research showed that GEMS is functional as regards to monitoring the environmental factors which influence apple production,which hence provide real-time service for registered farmers to guide their work.

Passengers' luggage is being reported missing in large amounts yearly at airports around the world due to several reasons. It causes tension to passengers at the destination airports and incurs excessive insurance costs for the airlines. An airport luggage protection system is presented in this paper to serve as a solution to this problem. The presented system ensures that passengers will exit the airport with only their own luggage. The system is based mainly on the RFID(radio frequency identification) technology. RFID tags, placed on both the passenger's ticket and luggage, will contain electronically stored encrypted information captured by scanning luggage tags with a barcode reader. In addition, a camera is used to capture the image of passenger's ticket and software tools developed for image processing are utilized to obtain data for a reference database. A prototype system has been developed and successfully tested.

The connectives are essentially the logical operations on propositions,two valued logic system is homomorphic with the Boolean algebra <{0,l},┐,∨,∧>,so all connectives may be defined by the truth value functions on {0,1}.In probabilistic logic,any function on[0,1]isn't true of all propositions because of propositional meanings.A probabilistic logic system is the logical description of a probabilistic space,the event domain in a probabilistic space is a set algebra,and probabilistic logic system is a Boolean algebra homomorphic with set *** connectives can be defined exactly by set functions on event domain instead of the truth value functions on[0,1].The classical formal system of propositional calculus is applicable to probabilistic propositions completely.

A class of discrete-time,dynamic supergames played by infinitely many players on tree is *** player plays a number of two-person games with her neighbors simultaneously and updates her strategy stochastically based on the information from her neighbors' strategies and the payoff she gets. Under the conditions of the pre-specified updating rules and the transition probabilities,the relevant strategy evolution process of the supersgame is proved to be a reversible Markov chain. The invariant Gibbsian measures which represent the long-run equilibrium plays with binary strategy and symmetric payoffs are *** are well known Ising models on trees which exhibit phase transition phenomena in certain cases.
