Audio-form presentation of text messages

Abstract: A text message generated at a sending device is converted into audio form by a message-conversion system for delivery to a target recipient. This conversion is effected in a manner enabling emotions, encoded by indicators embedded in the text message, to be expressed through multiple types of presentation feature in the audio form of the message. The mapping of emotions to feature values is pre-established for each feature type whilst the sender selection of one or more feature types to be used to express encoded emotions is specified by type indications inserted into the message at its time of generation.

A system, method and article of manufacture for processing a plurality of transactions from a single initiation point on a multichannel, extensible, flexible architecture

Abstract: An architecture for processing a plurality of transactions from a single point of initiation is disclosed. The initiating computer selects a terminal identification token, and associates the token with a transaction request, thereby ensuring the association of the transaction with a unique terminal identification despite being originated by the same terminal. The tokens are obtained from a token table, which contains a row for each token defined to the system. The table includes a column for the token, a column that identifies a system with which the token may be used, and a column that identifies a date and time field indicating when a particular token was selected for use. A null value in the date-time field indicates that the token for that row is not in use. A query operation selects a token with a null date-time value, and a set operation sets the date-time value to the then-current time to mark it in use. At the conclusion of the transaction, a set operation sets the date-time value to null, enabling the token to be reused for another non-concurrent transaction.

Embedding web access functionality into a device for user interface functions

Abstract: Web access functionality is embedded in a device to enable low cost widely accessible and enhanced user interface functions for the device. A web server in the device provides access to the user interface functions for the device through a device web page. A network interface in the device enables access to the web page by a web browser such that a user of the web browser accesses the user interface functions for the device through the web page.

Minerva: An automated resource provisioning tool for large-scale storage systems

Abstract: Enterprise-scale storage systems, which can contain hundreds of host computers and storage devices and up to tens of thousands of disks and logical volumes, are difficult to design. The volume of choices that need to be made is massive, and many choices have unforeseen interactions. Storage system design is tedious and complicated to do by hand, usually leading to solutions that are grossly over-provisioned, substantially under-performing or, in the worst case, both.To solve the configuration nightmare, we present minerva: a suite of tools for designing storage systems automatically. Minerva uses declarative specifications of application requirements and device capabilities; constraint-based formulations of the various sub-problems; and optimization techniques to explore the search space of possible solutions.This paper also explores and evaluates the design decisions that went into Minerva, using specialized micro- and macro-benchmarks. We show that Minerva can successfully handle a workload with substantial complexity (a decision-support database benchmark). Minerva created a 16-disk design in only a few minutes that achieved the same performance as a 30-disk system manually designed by human experts. Of equal importance, Minerva was able to predict the resulting system's performance before it was built.

Tycoon: An implementation of a distributed, market-based resource allocation system

Abstract: Distributed clusters like the Grid and PlanetLab enable the same statistical multiplexing efficiency gains for computing as the Internet provides for networking. One major challenge is allocating resources in an economically efficient and low-latency way. A common solution is proportional share, where users each get resources in proportion to their pre-defined weight. However, this does not allow users to differentiate the value of their jobs. This leads to economic inefficiency. In contrast, systems that require reservations impose a high latency (typically minutes to hours) to acquire resources. This paper describes Tycoon, a market based distributed resource allocation system based on proportional share. The key advantages of Tycoon are that it allows users to differentiate the values of their jobs, its resource acquisition latency is limited only by communication delays, and it imposes no manual bidding overhead on users. Experimental results using a prototype implementation of the design are included.
