This paper describes the design and application of time-enhanced, finite state models of discourse cues to the automated segmentation of broadcast news. We describe our analysis of a broadcast news corpus, the design of a discourse cue based story segmentor that builds upon information extraction techniques, and finally its computational implementation and evaluation in the Broadcast News Navig...

Dynamics of wireless communication, resource constraints, and application diversity pose significant challenges to data transport control in wireless sensor networks. In this chapter, we examine the issue of data transport control in the context of two typical communication patterns in wireless sensor networks: convergecast and broadcast. We study the similarity and differences of data transpor...

Kiwifruit requires a high quantity of nutrients that must be supplied through fertilization to obtain an optimum yield on a sustainable basis. This research was conducted to evaluate different fertilization methods including broadcast application (as control), deep placement of the fertilizer and fertigation, alone or in combination with foliar application and their effects on the yield, leaf m...

The successful practices of requirements engineering vary between application domains and are characterized by the nature of the application domain. One relatively peculiar application domain is the nuclear energy domain, which is characterized by the long life cycle of power plant operation and construction project, strict control of safety, and collaboration between several stakeholder groups...

Broadcast digitalization with its enormous benefits to the broadcasting industry will improve the quality of content of programs delivered by television stations. Africa has a switchover date of June, 2017. For Nigerians to have access to television broadcast once the switch over is completed, they must purchase high definition television sets or the set-up box. The awareness among urban dwelle...

his paper discusses how to provide reliable broadcast communication for multiple entities in d s distributed systems by using unreliable broadcast communication services. In real distribute ystems, each process in some application group rather sends every message to only the subt f set than all the processes in the group, and each process receives only messages destined to i rom some process in...

Broadcast is an important application in wireless networks, e.g. for video streaming, file distribution, or event notification. Wireless nodes are battery powered, their network lifetime depends on the energy consumption. Thus, energy efficiency is an important metric when designing broadcast protocols in infrastructureless and all-wireless networks. In this paper, we apply game theory to solve...

Broadcast encryption is an interesting application of cryptography which allows one to broadcast a secret to a changing group of intended recipients in such a way that no one outside this group can view the secret. Interest in using broadcast encryption techniques has grown considerably in recent years and such techniques have been integrated in many applications and technologies such as virtua...

The European Railway Agency (ERA) has the challenging task of establishing Common Safety Targets and Common Safety Methods throughout Europe. In this context, the harmonization of risk assessment methods is also discussed. The purpose of this paper is to present a new approach to risk assessment of technical systems in railway automation, which allows a rapid risk assessment while at the same t...

We consider the problem of maximizing the timeto-first-failure, defined as the time till the first node in the network runs out of battery energy, in energy constrained broadcast wireless networks. We discuss a greedy algorithm and prove that it solves the problem optimally for a broadcast application, in polynomial time, provided the complete power matrix and the battery residual capacities ar...
