defines the paths using the LP-optimization and after that allocates traffic using the NLP-optimization. The second
approximation divides traffic into parts and routes them consecutively using Dijkstra’s algorithm. Using the load balancing
algorithms as a starting point, the main goal of this thesis is to develop optimization algorithms that differentiate classes in
terms of mean delay. In the thesis, the differentiation is achieved by the use of both routing and WFQ-scheduling. Both optimal
and approximative algorithms are developed for the joint optimization of the WFQ-weights and routing. The load balancing
algorithms and the algorithms to differentiate classes are implemented and tested. As a result it is found that the use of the
approximations simplifies the optimization problem but still provides results that are near to optimal. The algorithms that try
to differentiate traffic classes by both routing and WFQ-scheduling provide the best performance.

Shifting from Risk regulation to Risks produced by regulation, this study attempts to explore the emergence and operation
of regulatory Ecologies as an organic approach for dealing with the issue of Risk and regulation. Objective of this paper is
to investigate the reasons behind regulatory failure and set a research agenda for dealing with the issue of technology
regulation, in a two-step approach. The first step is of a methodological nature: it calls for the adoption of an alternative stance
for studying the regulatory phenomenon by viewing the content of regulation as a direct result of its creation process and
focusing on the latter at least as much as on the former. The next step is to re-conceptualize regulation not as a means for
controlling and delimiting contingencies but as an instrument for their proliferation. The Open Source development of the
Gnutella protocol is illustrated as such an alternative regulatory paradigm and contrasted to a model of regulation based on
control of contingencies such as that of Trusted Computing Platform or Technical Measures of protection.

Microwave photonics has come of age and there are a number of military applications that could directly benefit from.
Optically controlled phased array antenna is one of the most widely pursued applications. The fiberoptic links are employed
for distribution of a variety of communication, intelligence, tracking, radar signals. There are a number of issues that dictate
the type of architecture that is employed for effective and reliable control of phased array. However, the most important benefit
is in the optical signal processing of microwave signals. Fiber delay lines are an important element of an signal processing
solutions.

This paper was prepared for NATO’s RTA Lecture Series No. 229 presented at the workshop of Optics-Microwave
Interactions held in September 2002. This lecture reviews recent developments of fiber-fed radio systems, an emerging
technology using fiber optic networks to distribute broad band RF and MMW signals for mobile and wireless systems over
long distance and within small cells. What is ‘Fiber Radio?’ Fiber Radio is a fiber-fed radio system using fiber optic links or
networks to distribute video, voice, and data for mobile and wireless applications. Antenna remoting is an example where
MMW subcarriers at 18, 24, 38, or 60 GHz with information are transmitted from central office to base stations. This emerging
technology has been demonstrated for applications such as community communications and pico-cell wireless systems for
both uplinks and downlinks broadcast carrying CATV, WLAN signals and data ranging from 2 to 156 Mbps. According to a
