Development of the hub port of Colombo, Sri Lanka
The Port of Colombo, Sri Lanka, is an important hub port in the Indian Ocean. A hub port is a port with mainly transhipment (and in this case container) throughput, which means that most of the cargo is not for the country itself, but for countries in the region. The yearly container throughput at the Port of Colombo reached its full capacity of 1.7 million TEU per year in 1997. Increasing waiting times for ships calling at the port are a result of this. Because of the costs of a waiting ship, shipping lines will choose other ports in the region such as Singapore, Salalah (Oman) or Dubai (United Arab Emirates) for their ships to go to. The aim of this study is to develop a plan for a New Container Terminal, which will give the Port of Colombo enough container throughput capacity for the next 25 years: till the year 2025.Hydraulic EngineeringCivil Engineering and Geoscience
Metadata-driven library design
Library development has greatly benefited form the wide adop- tion of virtual machines like Java and Microsoft .NET. Reflection services and first class dynamic loading have contributed to this trend. Microsoft introduced the notion of custom annotation, which is a way for the programmer to define custom metadata stored along reflection meta-data within the executable file. Re- cently, Java also has introduced an equivalent notion into the virtual machine. Custom annotations allow the programmer to give hints to libraries about his intention without having to intro- duce semantic dependencies within the program; on the other hand these annotations are read at runtime introducing a certain amount of overhead. The aim of this paper is to investigate the impact of this new feature on library design, focusing both on expressivity and performance issues
[a]C#: C# with a Customizable Code Annotation Mechanism
Reflective programming is becoming popular due to the increasing set of dynamic services provided by execution environments like JVM and CLR. With custom attributes Microsoft introduced an extensible model of reflection for CLR: they can be used as additional decorations on element declarations. The same notion has been introduced in Java 1.5. The extensible model proposed in both platforms limits annotations to class members. In this paper we describe [a]C#, 1 an extension of the C# programming language, that allows programmers to annotate statements or code blocks and retrieve these annotations at run-time. We show how this extension can be reduced to the existing model. A set of operations on annotated code blocks to retrieve annotations and manipulate bytecode is introduced. Finally, we discuss how to use [a]C# to annotate programs giving hints on how to parallel a sequential method and how it can be implemented by means of the abstractions provided by the run-time of the language
Orbit design for future SpaceChip swarm missions in a planetary atmosphere
The effect of solar radiation pressure and atmospheric drag on the orbital dynamics of satellites-on-a-chip (SpaceChips) is exploited to design equatorial long-lived orbits about the oblate Earth. The orbit energy gain due to asymmetric solar radiation pressure, considering the Earth's shadow, is used to balance the energy loss due to atmospheric drag. Future missions for a swarm of SpaceChips are proposed, where a number of small devices are released from a conventional spacecraft to perform spatially distributed measurements of the conditions in the ionosphere and exosphere. It is shown that the orbit lifetime can be extended and indeed selected through solar radiation pressure and the end-of-life re-entry of the swarm can be ensured, by exploiting atmospheric drag

Age and fertility: Can we wait until the early 30s?
Delaying the start of childbearing raises the issue of fertility postponed versus fertility foregone. One of the limits of previous studies of "How late can you wait?" is the difficulty of controlling for sexual activity. Data on the frequency and timing of intercourse within a menstrual cycle are uncommon. We use such data from the Menstrual Cycle Fecundability Study to study "Can we wait until the early 30s?". We model the effect of age on conditional fecundability, i.e., the probability of conception given that the couple is not sterile, simultaneously controlling for the effect of primary sterility and the frequency and timing of intercourse in each menstrual cycle. Can we wait until the early 30s for a first birth? Our evidence is yes (providing you are not already sterile) as the increase in the mean waiting time to conception is very modest and of little practical importance
Freely Annotating C#
Reflective programming is becoming popular due to the increasing set of dynamic services provided by execution environments like JVM and CLR. With custom attributes Microsoft introduced an extensible model of reflection for CLR: they can be used as additional decorations on element declarations. The same notion has been introduced in Java 1.5. The annotation model, both in Java and in C#, limits annotations to classes and class members. In this paper we describe [a]C# a, an extension of the C# programming language, that allows programmers to annotate statements and code blocks and retrieve these annotations at run-time. We show how this extension can be reduced to the existing model. A set of operations on annotated code blocks to retrieve annotations and manipulate bytecode is introduced. We also discuss how to use [a]C# to annotate programs giving hints on how to parallelize a sequential method and how it can be implemented by means of the abstractions provided by the run-time of the language. Finally, we show how our model for custom attributes has been realized
Da solução ao problema: um estudo sobre os conflitos, os impactos sócio-ambientais e as representações sociais envolvidas no uso e na gestão da água do aquífero Karst no município de Colombo (PR)
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciencias Humanas. Programa de Pós-graduação em Sociologia PolíticaEsta dissertação trata das representações sociais dos sujeitos envolvidos no uso e na gestão da água do Aqüífero Karst no Município de Colombo (PR), desde o início da sua utilização, em 1995, até os dias atuais. A exploração deste aqüífero, que no seu início tratava-se de uma solução institucional para o problema da falta de água na área urbana de Colombo, tornou-se o cenário de conflitos e impactos sócio-ambientais. Sob a luz do modelo de análise das representações sociais e da gestão patrimonial dos recursos naturais, analisam-se os fatores comuns do conflito e do uso da água entre três categorias de sujeitos envolvidos no uso e gestão da água do Aqüífero Karst: Agricultores, Técnicos da Sanepar e Órgãos Públicos. A pesquisa apontou que o conflito se manifestara, de um lado, pelos agricultores que alegavam a exploração irracional do aqüífero interferindo diretamente na disponibilidade de água dos mesmos para a irrigação da agricultura; e do outro lado, pela Sanepar que alegava a impossibilidade de interromper a captação do aqüífero em função de ser a única solução viável para atender a demanda por água em Colombo. Os resultados da análise das representações sociais dos sujeitos envolvidos, tanto sobre o conflito como em relação aos significados do uso da água, apontaram uma vinculação entre as representações dos sujeitos com o papel social que os mesmos desenvolvem. Na categoria dos Agricultores, os resultados demonstraram que a água representa a manutenção tanto da sobrevivência física como da renda econômica familiar dos sujeitos, sendo causa motivadora do conflito. Na categoria dos Técnicos da Sanepar os resultados vincularam com uma das missões da empresa, o abastecimento público. E nos Órgãos Públicos, os resultados relacionaram-se com a missão social que os mesmos representam, como a gestão, fiscalização, licenciamento ambiental e mediação de conflitos sociais e ambientais. This thesis deals with the social representations of the subjects involved in the use and the management of the water on Karst Aquifer in the City of Colombo (PR), since the beginning of its use, in 1995, until the current days. The exploration of this aquifer, that in its beginning it was about an institutional solution for the problem of the water lack in the urban area of Colombo, became the partner-ambient scene of conflicts and impacts. It was used in this thesis the model of analysis of the social representations and the patrimonial management of the natural resources. One analyzed the common factors of the conflict and of the use of the water on three categories of involved citizens in the use and management of Karst Aquifer water: Farmers, Technicians of Sanepar Company and Public Agencies. The research indicated that the conflict expressed, on the one side, by the farmers claiming that the irrational exploitation of Karst Aquifer interfered directly on the availability of water from them for irrigation agriculture. The other side, by Sanepar claiming the impossibility of stops the capture of this Aquifer in line to be the only viable solution to meet the demand for water in Colombo City. The results of analysis of social representations of the subjects involved, as much on the conflict as in relation to the meanings of the use of the water, pointed a linkage between the representations of the subjects with the social role that they develop. In the category of farmers, the results showed that the water represents both maintenance of the physical survival as of the familiar economic income of the citizens, being the motivating factor of the conflict. In the category of Technicians of Sanepar Company, the results linked with one of the missions of the company, the supply public. And in the Public Agencies, the results related with the social mission that they represent, as the management, supervision, licensing and environmental mediation of social conflicts and environmental
