Abstract—This paper summarizes the current state of the art and recent trends in software engineering economics. It provides an overview of economic analysis techniques and their applicability to software engineering and management. It surveys the field of software cost estimation, including

, and the multiple networks include 3GPP and WLAN type networks. The report covers the diverse usage models with multiple external interfaces from a security point of view, without incorporating significant changes to the 3GPP and WLAN infrastructure. It also overs the impact on current security specifications for 3

of outstanding issues in evolutionary biology, including the analysis of large phylogenetic trees and complex evolutionary models and the detection of the footprint of natural selection in DNA sequences. T he idea that species are related through a history of common descent is an old one, predating Darwin. Yet

, audited, and paid for in a timely fashion. Currently the procedure used to pay off these circuits is labor intensive and takes too long to perform. When the invoices are not paid on time, the telecommunications company is charged with late penalties. Some issues which contribute to the problem: • 50

The informal requirements for the invoicing case study are analysed and interpreted. This leads to a high-level specification architecture that can be formalised. Specifications are presented in LOTOS (Language Of Temporal Ordering Specification). For comparison, specifications are also presented

Abstract. This paper introduces the approach CBRDIA (Case-based Reasoning for Document Invoice Analysis) which uses the principles of case-based reasoning to analyze, recognize and interpret invoices. Two CBR cycles are performed sequentially in CBRDIA. The first one consists in checking whether a

The Invoicing case study is a typical business system proposed by Henri Habrias as a common example for a contest on the capacity of particular formal methods to capture requirements from the client. For this, the case study is informally described by half a page of English text. In this report, we

Abstract This chapter is an attempt at clarifying the current scene of sometimes competing action logics, looking for compatibilities and convergences. Current paradigms for deliberate action fall into two broad families: dynamic logics of events, and STIT logics of achieving specified effects. We

The general features of the cosmic-ray spectrum have been known for a long time. Although the basic approaches to understanding cosmic-ray propagation and acceleration have also been well understood for many years, there are several questions of great interest that motivate the current intense
