Current approaches to power management are based on operating systems with full knowledge of and full control over the underlying hardware; the distributed nature of multi-layered virtual machine environments renders such approaches insufficient. In this paper, we present a novel framework for energy management in modular, multi-layered operating system structures. The framework provides a unif...

C leanliness of parts and assemblies has always been an important factor for product yield in the disk drive industry. The challenge is that most disk drive parts are manufactured by conventional material processing methods, such as machining. stamping. and molding. Ultimately, the manufacturing process normally requiring the use of oils, coolants, and abrasive tools becomes the primary source ...

VMware ESX Server offers three choices for managing disk access in a virtual machine—VMware Virtual Machine File System (VMFS), virtual raw device mapping (RDM), and physical raw device mapping. It is very important to understand the I/O characteristics of these disk access management systems in order to choose the right access type for a particular application. Choosing the right disk access m...

to reduce the storing space and handling costs for hay/straw bales, recompressing the original bales after adequate hay drying is recommended. in this project, a recompression machine was designed, constructed and evaluated. solidwork and nastran software were employed to model, and to analyze the stresses in the components of the machine, respectively. the components of the machine consisted o...

The design of a high-performance, cost-eeective, machine for retrieving textual data is discussed in this paper. High performance and cost eeectiveness are achieved by a combination of low-cost hard disks, software ltering techniques, and a large amount of main memory. The discussion focuses on the signature processor, which is based on the partitioned signature le technique, and the mass stora...

The ability of object recognition system is to recognize a large number of objects constrained by a variety of factors such as the selection of a feature extraction method, quality of the images, and the classification models. This paper presents an approach to the recognition of complex shape objects using shape representation features. The shape representation features are the disk components...

In virtual machine environments each application is often run in its own virtual machine (VM), isolating it from other applications running on the same physical machine. Contention for memory, disk space, and network bandwidth among virtual machines, coupled with an inability to share due to the isolation virtual machines provide, leads to heavy resource utilization. Additionally, VMs increase ...
