The build, operate, and transfer ("BOT") approach to infrastructure projects in developing countries
No full textBuild, operate and transfer (BOT) projects are exceedingly complex from both a financial and a legal point of view. They require an extended period of time to develop and negotiate. If a country is not able to finance all of its needed infrastructure on the basis of budgetary resources or sovereign borrowings, the BOT approach is an option to be considered. A BOT project appears to provide some"additionality"in tapping sources of private sector financing which otherwise might not be available. The sponsors'commitment of substantial equity to a project assures that they will also remain committed to the project's successful operation over the concession period. Their investment provides a strong incentive to have the project perform above its minimum expectations. Likewise, having the design, implementation and operation of a BOT project largely in the hands of the private sector may provide economies and efficiencies that will balance out or even outweight the higher financing costs of non sovereign borrowing and equity investment. The BOT approach appears to be a useful possible alternative to the conventional financing and operation of infrastructure projects in developing countries.Municipal Financial Management,Public Sector Economics&Finance,Housing Finance,Environmental Economics&Policies,Banks&Banking Reform

"On Modelling Negotiations within a Dynamic Multi-objective Programming Framework: Analysis of Risk Measurement with an Application to Large BOT Projects"
No full textThe dynamic and multi-objective programming is used here to establish a risk measurement model. We develop an iterative algorithm and the convergence conditions for the model solution. The results obtained from the model developed here show that the sum of the interactive utility value (IUV) could determine whether or not the interactive relationship is characterized by independence among negotiators. In addition, the numerical example shows that this risk measurement model of the negotiation group can reflect risk assessment by the negotiation group for certain events and can analyze interaction characteristics among negotiators. We show the feasibility and applicability of the model and the exact solution algorithm, and their policy relevance for analyzing BOT projects.
Turmell-Bot
No full textWe present the design of the Turmell-Bot,
an assistive robot for human ankle physical therapy. We
studied ankle biomechanics from a multidisciplinary holis-
tic approach and analyzed the two-rotational serial chain
known as the talocrural and subtalar axes. Moreover, we im-
plemented a primary ankle analogous to the two-rotational,
cable-driven mechanism. And by using the screw theory
framework, we study the tensegrity and mobility interaction
between ankle-foot tendons and joints. Then, we synthe-
sized a four-tendon-driven robot that considers the human
ankle serial chain in the closed-loop mechanism. We repre-
sented the human ankle axis by Plücker line coordinates,
integrating a draw-wire sensor system to capture the ankle
movements and estimate the ankle axes’ position and ori-
entation. Then, we used the axis coordinates projected to
the base and platform planes to reconfigure the cable an-
chor endpoints to equilibrate the antagonistic cable-driven
actuators. Finally, we computed the workspace, the kine-
matics and validated the robot’s stability with the software

Inferring and Visualizing Social Networks on Internet Relay Chat
No full textInternet Relay Chat is a system that allows groups of people to collaborate and chat from anywhere in the world. Clearly defined by several RFC documents, it is arguably the most standard real-time chat system currently in use. This paper describes a method of inferring the social network of a group of IRC users in a channel. An IRC bot is used to monitor a channel and perform a heuristic analysis of events to create a mathematical approximation of the social network. From this, the bot can produce a visualization of the inferred social network on demand. These visualizations reveal the structure of the social network, highlighting connectivity, clustering and strengths of relationships between users. Animated output allows viewers to see the evolution of the social network over time. Some novel ideas for future work are discussed, showing other useful applications of this system
