3G中的QoS结构及无线资源分配策略

在3G（第3代移动通信系统）中，为了给不同类型的业务提供不同级别的端到端QoS，网络资源必须进行合理分配。QoS和资源分配是密不可分的，而无线资源分配显得尤为重要。文中提出了UMTS的QoS结构，分3部分对空中接口部分的QoS（即无线资源分配策略问题）进行了讨论：首先提出了一种RRA算法，接着讨论了W－CDMA和TD－CDMA系统的无线资源分配问题，最后讨论了下行链路及上行链路的呼叫允许控制（CAC）。     

ATM网络中CBR业务连接允许控制机制

该文提出了一种基于有限容量缓冲区下CBR业务信元丢失率和最小速率替换的线性近似连接允许控制机制，与原有的CAC机制相比，该文的CAC机制存在两个方面的改进：一方面，使用更合理、精确的CLR表达式，从而能够作出更为准确的连接允许判断：另一方面，能够提供服务质量服务。

New developments in speciality polymers: polymeric stabilizers

Many new speciality polymers have been developed in the last few years. In this paper polymeric stabilizers (antioxidants, flame retardants and ultraviolet stabilizers) will be discussed. Polymeric antioxidants of the hindered-phenol type, copolymers of 2,6-ditertiarybutyl-4-vinyl(or isopropenyl)phenol with styrene, methyl methacrylate, or more importantly butadiene or isoprene have been prepared; hydrogenation of the latter copolymers gave copolymers of the two polymerizable phenolic antioxidants with ethylene or ethylene/propylene. The polymeric antioxidants have been blended with diene polymers and selected polyolefins and have improved the long-term oxidative stability of these polymers. Polymeric flame retardants have been prepared by copolymerizing styrene and/or acrylonitrile with acrylates and methacrylates of aliphatic bromine-containing alcohols or bromine-containing phenols. Polymers with polymer-bound flame retardants have a higher limiting oxygen index compared with the original polymer. A new class of polymerizable ultraviolet stabilizers has also been developed; these stabilizers are styryl, α-methylstyryl, acryloyl and methacryloyl derivatives of 2(2-hydroxyphenyl)2H-benzotriazoles. These monomers have been copolymerized with styrene, acrylates and methacrylates. 2(2-Hydroxyphenyl)2H-benzotriazoles substituted in the 4 position of the benzotriazole ring with hydroxyl, acetoxy or carboxyl groups suitable for incorporation into polyesters, polycarbonates, polyamides and epoxy resins have also been synthesized. All 2(2-hydroxyphenyl)2H-benzotriazole ultraviolet absorbers and the polymers into which they are incorporated have high light absorbency with γ_max between 330 and 350 nm and extinction coefficients in some cases as high as 4.5 × 10⁴ 1 mol^?1 cm^?1.     

澳大利亚2001～2002年度Internet业务市场回顾

在2001－2002年度中，澳大利亚Internet用户已超过总人口的50％。用户订购业务的类型有较大程度的变化，按月、季度和年度订购Internet业务的用户数量不断增长，免费订房、按小时付费和按容量接入的用户在减少。网上商业交易和政府业务在增加，政府积极实施公共Internet接入项目。澳大利亚各州和地区的ISP及相应的接入点数量逐渐减少，通信基础设施则进一步改善。

基于地理信息共享构建的流域生态环境分布式评价系统

流域生态环境评价是水利工程建设及评估的一个重要方面,目前,国内外流域管理机构都在积极开展该领域的研究和组织实施工作。在我国,由于流域管理机构之间信息孤岛现象严重,获取信息、特别是时间或空间上的连续信息非常困难,因此在研究大范围、长周期的生态环境影响评价方面受到非常严重的制约。文中以web service技术为基础,考虑构建完全基于服务的地理信息共享系统,以解决我国流域机构中目前普遍存在的空间信息共享、特别是互操作难题,并且以湖北省区域作为范例构建一个多服务器、多模型的服务系统原型,实现了在该区域内进行流域生态环境评价。     

Bacteriological Safety of Swine Carcasses Treated with Reconditioned Water

Swine carcass microflora were evaluated for selected foodborne pathogens after exposure to reconditioned water during scalding, dehairing, and polishing operations. Reused water had been reconditioned and chlorinated. Rodac plates applied to hams were used to assess carcass microflora. Water samples were enumerated using membrane filtration or spiral plating. Sampling was at mid-week throughout the year. Total aerobic plate counts on hams were unaffected by treating with potable or reconditioned waters. No differences were observed for staphylococci, enterics, fecal streptococci, Listeria monocytogenes, coliforms, and Aeromonas levels. A preevisceration potable water carcass wash reduced the bacterial load, regardless of initial treatment. Bacterial counts on carcasses paralleled those in water. Reuse is an alternative to potable water for initial slaughter operations without diminishing bacteriologic safety.
