Fluorescence Assay for Polymerase Arrival Rates

To engineer complex synthetic biological systems will require modular design, assembly, and characterization strategies. The RNA polymerase arrival rate (PAR) is defined to be the rate that RNA polymerases arrive at a specified location on the DNA. Designing and characterizing biological modules in terms of RNA polymerase arrival rates provides for many advantages in the construction and modeling of biological systems. PARMESAN is an in vitro method for measuring polymerase arrival rates using pyrrolo-dC, a fluorescent DNA base that can substitute for cytosine. Pyrrolo-dC shows a detectable fluorescence difference when in single-stranded versus double-stranded DNA. During transcription, RNA polymerase separates the two strands of DNA, leading to a change in the fluorescence of pyrrolo-dC. By incorporating pyrrolo-dC at specific locations in the DNA, fluorescence changes can be taken as a direct measurement of the polymerase arrival rate.

ICTINEUAUV wins the First SAUC-E competition

A pioneer team of students of the University of Girona decided to design and develop an autonomous underwater vehicle (AUV) called ICTINEU-AUV to face the Student Autonomous Underwater Challenge-Europe (SAUC-E). The prototype has evolved from the initial computer aided design (CAD) model to become an operative AUV in the short period of seven months. The open frame and modular design principles together with the compatibility with other robots previously developed at the lab have provided the main design philosophy. Hence, at the robot's core, two networked computers give access to a wide set of sensors and actuators. The Gentoo/Linux distribution was chosen as the onboard operating system. A software architecture based on a set of distributed objects with soft real time capabilities was developed and a hybrid control architecture including mission control, a behavioural layer and a robust map-based localization algorithm made ICTINEU-AUV the winning entry

Neptune: a hil simulator for multiple UUVs

This paper overviews the field of graphical simulators used for AUV development, presents the taxonomy of these applications and proposes a classification. It also presents Neptune, a multivehicle, real-time, graphical simulator based on OpenGL that allows hardware in the loop simulations

Dynamic bandwidth management as part of an integrated network management system based on distributed agents

We present a system for dynamic network resource configuration in environments with bandwidth reservation and path restoration mechanisms. Our focus is on the dynamic bandwidth management results, although the main goal of the system is the integration of the different mechanisms that manage the reserved paths (bandwidth, restoration, and spare capacity planning). The objective is to avoid conflicts between these mechanisms. The system is able to dynamically manage a logical network such as a virtual path network in ATM or a label switch path network in MPLS. This system has been designed to be modular in the sense that in can be activated or deactivated, and it can be applied only in a sub-network. The system design and implementation is based on a multi-agent system (MAS). We also included details of its architecture and implementation

Interacting software-agents to support a kind of expert supervision systems

Expert supervision systems are software applications specially designed to automate process monitoring. The goal is to reduce the dependency on human operators to assure the correct operation of a process including faulty situations. Construction of this kind of application involves an important task of design and development in order to represent and to manipulate process data and behaviour at different degrees of abstraction for interfacing with data acquisition systems connected to the process. This is an open problem that becomes more complex with the number of variables, parameters and relations to account for the complexity of the process. Multiple specialised modules tuned to solve simpler tasks that operate under a co-ordination provide a solution. A modular architecture based on concepts of software agents, taking advantage of the integration of diverse knowledge-based techniques, is proposed for this purpose. The components (software agents, communication mechanisms and perception/action mechanisms) are based on ICa (Intelligent Control architecture), software middleware supporting the build-up of applications with software agent features

Apunts de tecnologia de materials polímers [versió html]

Aquests apunts corresponen a una introducció a la tecnologia dels plàstics. Es tracta d'una visió general dels processos de transformació en la qual s'analitzen tant les tècniques concretes (injecció, extrusió...) com el comportament del material durant el processament. Per això, el temari comença amb una descripció de les propietats dels materials més rellevants per a la seva transformació (comportament tèrmic i reològic). Durant la descripció de les tècniques es posa l'èmfasi en com el processament pot modular les propietats del material. Tot i que el temari inclou tant els termoplàstics com els termoestables i elastòmers, donem més importància als primers

Mejoramiento Productivo "Apparel Basic Ltda"

Para el presente trabajo realizado en la Universidad del Rosario, buscamos hacer un mejoramiento productivo de la empresa Apparel Basic Ltda. Teniendo en cuenta todas las herramientas aprehendidas durante la academia y aplicando esto a una empresa del sector real de confecciones. Se centrara el análisis principalmente en las tres áreas donde se observan los mayores problemas organizacionales: Producción, manejo de inventarios y entrega de producto. En el primer análisis se realizara todo el estudio del proceso de producción, teniendo en cuenta la distribución en planta, las rutas críticas de proceso, los diagramas de flujo de producto, el análisis de las principales referencias, entre otros. Todo esto con el fin de identificar los principales errores y poder proponer herramientas y procesos de mejora que sean de ayuda para esta organización. El siguiente análisis se desarrollara en el manejo de inventarios; dentro de este aspecto se analizaran la distribución de las bodegas de producto, la identificación de los productos de mayor rotación, el planteamiento de indicadores de gestión, entre otros procesos, con el fin de identificar procesos benéficos para la empresa que aceleren y mejoren el flujo de producto al interior de la organización. Luego de esto, se analiza todo el proceso de alistamiento y entrega de producto ya que es uno de los principales problemas dentro de la organización porque se esta incumpliendo con los pedidos de los clientes lo que genera un problema de insatisfacción por parte de los clientes.
