PODIO: recent developments in the Plain Old Data EDM toolkit

PODIO is a C++ toolkit for the creation of event data models (EDMs) with a fast and efficient I/O layer. It employs plain-old-data (POD) data structures wherever possible, while avoiding deep object-hierarchies and virtual inheritance. A lightweight layer of handle classes provides the necessary highlevel interface for the physicist. PODIO creates all EDM code from simple instructive YAML files, describing the actual EDM entities. Since its original development PODIO has been very actively used for Future Circular Collider (FCC) studies. In its original version, the underlying I/O was entirely based on the automatic streaming code generated with ROOT dictionaries. Recently two additional I/O implementations have been added. One is based on HDF5 and the other uses SIO, a simple binary I/O library provided by LCIO. We briefly introduce the main features of PODIO and then report on recent developments with a focus on performance comparisons between the available I/O implementations. We conclude with presenting recent activities on porting the well-established LCIO EDM to PODIO and the recent EDM4hep project.

A Generic Model of the World and Intelligence

The resurgence of interest in Artificial Intelligence and advances in several fronts of AI, machine learning with neural network in particular, have made us think again about the nature of intelligence, and the existence of a generic model that may be able to capture what human beings have in their mind about the world to empower them to present all kinds of intelligent behaviors. In this paper, we present Constrained Object Hierarchies (COHs) as such a generic model of the world and intelligence. COHs extend the well-known object-oriented paradigm by adding identity constraints, trigger constraints, goal constraints, and some primary methods that can be used by capable beings to accomplish various intelligence, such as deduction, induction, analogy, recognition, construction, learning and many others.In the paper we will first argue the need for such a generic model of the world and intelligence, and then present the generic model in detail, including its important constructs, the primary methods capable beings can use, as well as how different intelligent behaviors can be implemented and achieved with this generic model.

Situation Approach as Success Factor of Mobile Marketing

The success of Mobile Marketing is to a large extent dependent on two factors: (1) the situation appropriateness, where demands are made on the ability of the supplier to process all the central characteristics of a customer situation and turn them into an offer that is appropriate to the situation; (2) the economic success of the supplier depends on the economic potential of the situation and his accurate appraisal of it. The supplier therefore has to model both the specific features and the profit potential of the various customer situations at the right time and in the right way. This chapter is going to demonstrate that the success of Mobile Marketing measures can be guaranteed by a synergic interplay of market and result orientation. On the one hand customer situations are systemized and placed in the context of an integrated Customer Relationship Management system; on the other hand the evaluation of situations, reference object hierarchies, and the various levels of situation profit and loss statements are shown.
