In this piece we take a brief peek at the possible world of robotic companions. In such a world, robots are adopted as butlers in our homes, as baby watchers, as friends and in general as life companions. For example, Helen lives with a robotic companion named Schpuffy. In the morning, Schpuffy checks Helen's schedule and finds out she has an appointment with a neighbor to take a walk at 8:30 a.m. Schpuffy recognizes that it takes 30 minutes for her to prepare to go for a walk and wakes her up at 8:00 a.m. After she gets up, Schpuffy reminds Helen of her appointment at 8:30 a.m. While she gets dressed, Schpuffy lets her know that current weather is very cold and suggests that she wear thermal clothing. When she's about to leave the house, Schpuffy says "good bye" to her and locks the door as she leaves. Schpuffy hasn't gained majored acceptance. It's not in every home or even in a tiny fraction of homes. However, it's a bold new research that is taking shape with early commercial products already hitting the marketplace. It could soon be the chief appliance in your home, or the new interface technology for smart spaces. 相似文献

Scene change detection techniques for video database systems 总被引:1,自引:0,他引:1

Scene change detection (SCD) is one of several fundamental problems in the design of a video database management system (VDBMS).
It is the first step towards the automatic segmentation, annotation, and indexing of video data. SCD is also used in other
aspects of VDBMS, e.g., hierarchical representation and efficient browsing of the video data. In this paper, we provide a
taxonomy that classifies existing SCD algorithms into three categories: full-video-image-based, compressed-video-based, and
model-based algorithms. The capabilities and limitations of the SCD algorithms are discussed in detail. The paper also proposes
a set of criteria for measuring and comparing the performance of various SCD algorithms. We conclude by discussing some important
research directions. 相似文献

Fifteen Baladi and 20 Angora intact males raised together from birth until 8 months of age were grown on a commercial concentrate mixture fed at the rate of 0·6 kg/head/day with chopped wheat straw fed at 0·5 kg/head/day for 14 weeks. Body measurements were taken before slaughter and carcass measurements and offal weights after it. The right sides of all carcasses were dissected into cuts, weighed and deboned. Fat was separated from the 9-10-11 rib joints and estimated. The two breeds did not significantly differ in birth weight, weaning weight, carcass weight, dressing percentage, most body measurements, all carcass measurements and most offal weights. Sigmificant differences were only found in body length, height at withers, weights of spleen and kidney fat. However, the Baladi had significant heavier loin and shoulder (P < 0·05) and breast and flank (P < 0·05) than the Angora which had heavier legs (P < 0·05). The carcasses of the two breeds had very similar percentage of edible meat (68·38 versus 68·65), lean (57·47 versus 57·38) and fat in the rib joint (10·91 versus 11·27). 相似文献

This paper examines channel choice and the digital divide in Egyptian electronic government or e-government. Citizens have access to a variety of service delivery channels when they initiate contact with their government, ranging from e-government to more traditional channels such as the phone and in-person visits to a government office. This paper examines the extent of use of both contact channels for citizens and the impact of the digital divide on channel use. A public opinion survey of Egyptian citizens was analyzed, and the results showed that there was a digital divide in the use of e-government by citizens. The digital divide also extended to other contact channels such as the phone and when citizens used multiple contact channels for public service delivery. The results of this study imply that for the development of e-government, especially in the context of a developing country such as Egypt, policy-makers need to understand that e-government is one of many channels that citizens can use when they initiate contact with their government. The results of this study should encourage policy-makers to recognize the importance of public service delivery in a multichannel environment. 相似文献

In this article, the corrosion behavior of Cu? Fe and Cu? Al? Fe was studied in H2SO4 solutions in the absence and presence of different concentrations of some inorganic additives, Na2MoO4, K2Cr2O7, KIO3, and Na2B4O7. The techniques of measurements used were open‐circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy. The polarization measurements indicated that the corrosion current, Icorr, of Cu? Fe is less than that of Cu? Al? Fe. The investigated additives in H2SO4 shifted Ecorr to more positive values and increases Icorr. Impedance measurements indicated that Nyquist plots for Cu? Fe may be regarded as a semi‐circle in early stages of immersion and tends to be a part of semi‐circle with elapse of time and a well‐defined inductive loop appears. In case of Cu? Al? Fe, the Nyquist plots tends to be semi‐circle or depressed semi‐circle. The values of Rp for Cu? Fe are higher than those for Cu? Al? Fe. On the other hand, the values of Cdl for Cu? Fe are lower than those obtained for Cu? Al? Fe. The presence of these additives in H2SO4 solutions decreases the values of polarization resistance (Rp) and increases the values of corrosion current density (Icorr) and capacitance of double layer (Cdl). 相似文献
