Pattern Recognition and Machine Learning

Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

We present Bungie, an approach based on applicationlevel protocols that precisely capture the causality inherent to the interactions among agents. We show through patterns and examples how Bungie provides abstractions for achieving fault tolerance.

Bungie: Improving Fault Tolerance via Extensible Application-Level Protocols

Current approaches of specifying business processes describe the implementation of a process rather than the interactions that are expected from the agents that participate in it. This means that the specification is neither flexible, nor reusable. We propose an approach of developing business processes from commitment-based protocols. Our approach results in protocols that are reusable across applications and processes that are flexible. An essential ingredient of our approach is developing an operational semantics of commitments that allows contextual (policy-specific) reasoning about them.

Commitments for Flexible Business Processes

Multiagent systems (MAS) are an important paradigm for building complex systems, especially cooperative information systems. Despite much interest in MAS construction, there has not been sufficient progress on the corresponding conceptual modeling representations and techniques. We believe that further extensions to conceptual modeling to include aspects of actions and organizations will be essential for MAS development. These goals are broader than conceptual modeling is traditionally understood, but are essential to deal with the interactive and dynamic aspects of modern applications. We describe an approach termed interaction-oriented programming, which incorporates functionality geared toward coordination, commitment management, and collaboration. This functionality is naturally thought of as providing a conceptual metamodel for describing MAS. We suggest some preliminary methodologies pertaining to the design of coordination and commitment requirements.

Conceptual Modeling for Multiagent Systems: Applying Interaction-Oriented Programming.

BSPL, the Blindingly Simple Protocol Language, is a recent approach for declaratively expressing service communication protocols that involves only two main constructs: a way to specify a message as an atomic protocol and a way to compose protocols. BSPL supports the Local State Transfer architectural style for decentralized service enactment. BSPL offers significant gains in expressing protocols (i.e., specifications) that decouple participants in service engagements (i.e., agents) as much as possible given the causal constraints induced from the information exchanged by them. Importantly, BSPL relies exclusively on how appropriate information flows are induced from the specification. This paper proposes Bliss, a conceptual model for interaction that is based on information flow. The idea behind Bliss is to incrementally develop the information needed to complete the social object that a protocol computes. Bliss yields simple steps to help ensure that the resulting protocol adequately captures the given requirements with respect to the social object.

Bliss: Specifying Declarative Service Protocols

which are substantially larger than those reached by traditional computers. Communicators are small handheld devices that combine the features of PDAs and palmtop computers with those of telephones. Communicators are widely believed to be the next big wave of devices with projected worldwide market penetration exceeding that of conventional desktop computers. Because of their being ready at hand as people go about their daily business, Communicators provide a natural platform on which to conduct e-commerce. However, Communicators pose major technical challenges because of their physical limitations and likely modes of usage. They offer small screens for presentation, difficult input, low bandwidth, and intermittent and unreliable connectivity. Further, people use their Communicators while on the run, in awkward settings, and may break, lose, or have their Communicators stolen. We describe an approach that addresses the above challenges while retaining the convenience of using Communicators. This approach integrates innovations in user interfaces and backend systems for information access and transactions. Norman argues forcefully that information appliances (or “invisible computers”) of the sort of communicators can fundamentally be more usable and thus more popular than traditional computers [5]. We agree with this assessment and think of communicators and their relatives as becoming ever more popular. (We revisit other aspects of Norman’s position in section 4.4.) As communicators (and related devices such as palmtops and PDAs) become more prevalent, it is natural that they will be used to conduct electronic commerce. Indeed, because communicators are carried by people all the time, in many cases, communicators are likelier to be used for e-commerce than traditional desktop computers. E-Commerce involves a number of activities. Of these, the following are especially relevant from the perspective of the consumer:
