We provide a formal framework for studying broadcasting schemes and design a family of schemes for broadcasting popular videos, called the Greedy Diskconserving Broadcasting (GDB) scheme. We analyze the resource requirements for GDB, i.e., the number of server broadcast channels, the client storage space, and the client I/O bandwidth required by GDB. The analysis shows that GDB exhibits a trade...

Applications running on a large distributed system face a dynamically changing environment. Thus, an application needs to adapt to new conditions or it will fail to continuously meet its specification. This is especially crucial if the application needs to implement a certain quality of service (QoS). Object-based middleware systems like CORBA implementations are currently not able to directly ...

Federated incremental learning best suits the changing needs of common Federal Learning (FL) tasks. In this area, large sample client dramatically influences final model training results, and unbalanced features are challenging to capture. paper, a federated framework is designed; firstly, part data preprocessed obtain initial global model. Secondly, help get importance whole each client, enhan...

In this article we argue that to provide compelling data-driven services to the mobile user, one often needs to deploy a customized client application on the mobile device. This client application usually has to communicate with applications running on a server “back-end”. To expedite the development of wireless services, companies are using mobile middleware platforms to connect mobile Java ap...

The information systems manager is often constrained by maintaining a certain threshold amount of memory for an organization. However, this requires more than technical and managerial resolutions, encompassing knowledge management for the group, eliciting tacit knowledge from the end users, and pattern and time series analyses of utilization for various applications. This paper proposes a frame...

Additional discussion of when a server should and should not advertise the STARTTLS extension (section 5) Changed the requirements on SMTP clients after receiving a 220 response.
