Optimal capacity management and planning in services delivery centers

This paper considers human server systems of queues that arise within the information technology services industry. We develop a two-phase stochastic optimization solution approach to effectively and efficiently address the capacity management and planning processes of information technology services delivery centers. A large collection of numerical experiments of real-world human server system environments investigates various issues of both theoretical and practical interest, quantifying the significant benefits of our approach as well as evaluating the financial-performance trade-offs often encountered in practice.     

Using the cloud to develop applications supporting geo-collaborative Situated Learning

Situated Learning stresses the importance of the context in which learning takes place. It has been therefore frequently associated with informal learning or learning outside the classroom. Cloud technologies can play an important role supporting this type of learning, since it requires ubiquitous computing support, connectivity and access to data across various scenarios: on the field, in the classroom, at home, etc. In this paper we first present the situated learning theory and how we can take advantage of services offered by Cloud Computing to implement computer applications implementing learning activities based on this theory, providing pertinent geographical information and discussion boards. Next we propose a software architecture schema which can be used as a basis for integrating existing cloud services into new applications supporting learning activities. Then we present two examples developed with this approach with its viability and advantages. These are discussed in the concluding chapter.     

Web服务的构建及其典型应用

Web服务基于标准的数据格式和协议,如XML、SOAP和HTTP,不同平台和操作系统的客户和服务端可以基于同样的协议,没有障碍地通信,Web服务客户端只需标识Web服务的位置及其可以调用的方法,就可以简单地使用Web服务。微软公司的.NET框架针对Web服务提供了广泛的支持。因此研究了.NET环境下Web Services的构建、处理流程,举例说明了Web服务的典型应用。     

基于WebServices和Ajax的实时传输系统架构

传统的Web系统无法满足用户的实时性要求,本文提出了基于Web Services和Ajax的Web数据实时传输系统,并进行了具体应用。传统的Web应用采用同步交互的方式,当负载较大而带宽较小时响应时间就会变长,甚至会出现超时现象。Web服务可以均衡Web服务器的负载,创建开放分布式系统;Ajax可以优化浏览器和服务器之间的数据传输,可以减少不必要的数据往返,减少带宽应用,减轻服务器的负担。结合二者可以有效地创建实时分布式Web系统,本文给出了二者结合进行数据传输的架构方案,并通过实例展示了其实现方法。
