Quick-Start for TCP and IP Status of this Memo By submitting this Internet-Draft, each author represents that any applicable patent or other IPR claims of which he or she is aware have been or will be disclosed, and any of which he or she becomes aware will be disclosed, in accordance with Section 6 of BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress. " Abstract This document specifies an optional Quick-Start mechanism for transport protocols, in cooperation with routers, to determine an allowed sending rate at the start and at times in the middle of a data transfer (e.g., after an idle period). While Quick-Start is designed to be used by a range of transport protocols, in this document we only specify its use with TCP. Quick-Start is designed to allow connections to use higher sending rates when there is significant unused bandwidth along the path and the sender and all of the routers along the path approve the Quick-Start Request. This document describes many paths where Quick-Start requests would not be approved. These paths include all paths containing routers, IP tunnels, MPLS paths, and the like that do not support Quick-Start. These paths also include paths with routers or middleboxes that drop packets containing IP options. Quick-Start requests could be difficult to approve over paths that include multi-access layer-two networks. This document also describes environments where the Quick-Start process could fail with false positives, with the sender incorrectly assuming that the Quick-Start request had been approved by all of the routers along the path. As a result of these concerns, and as a result of the difficulties and seeming absence of motivation for routers such as core routers to deploy Quick-Start, Quick-Start is being proposed as a mechanism that could be of use in controlled environments, and not as a mechanism that would be intended or appropriate for ubiquitous deployment in the global Internet.

Analysis & Performance Evolution of IRIS Recognition SVD and EBP Algorithms using Neural Network Classifier

Iris recognition, a relatively new biometric technology, has great advantages, such as variability, stability and security, thus it is the most promising for high security environments. Hence numbers of IRIS recognition algorithms are available, techniques we purposed such as SVD (singular value decomposition) this technique will be used to extract the features of iris.The nonuseful information such as sclera, pupil, eyelashes and eyelids are removed and Region of Interest (ROI) is extracted. Then the Iris template is generated to reduce the information thereby concentrating only on the ROI. The details of this combined system named as Iris Pattern recognition using neural Network Approach. All IRIS recognition algorithms are evaluated on the basis of classification rate obtained after changing different parameters such as number of classes, Training and Testing patterns, SVDTo reduce complexity of layered neural network the dimension of input vectors are optimized using Singular Value Decomposition (SVD). The optimum classification values are obtained with SVD 20 dimension and maximum number of classes as 9 with the state-of-the art computational resources. The details of this combined system named as SVD-EBD system for Iris pattern recognition.
ImageCLEF: Experimental Evaluation in Visual Information Retrieval

The creation and consumption of content, especially visual content, is ingrained into our modern world. This book contains a collection of texts centered on the evaluation of image retrieval systems. To enable reproducible evaluation we must create standardized benchmarks and evaluation methodologies. The individual chapters in this book highlight major issues and challenges in evaluating image retrieval systems and describe various initiatives that provide researchers with the necessary evaluation resources. In particular they describe activities within ImageCLEF, an initiative to evaluate cross-language image retrieval systems which has been running as part of the Cross Language Evaluation Forum (CLEF) since 2003. To this end, the editors collected contributions from a range of people: those involved directly with ImageCLEF, such as the organizers of specific image retrieval or annotation tasks; participants who have developed techniques to tackle the challenges set forth by the organizers; and people from industry and academia involved with image retrieval and evaluation generally. Mostly written for researchers in academia and industry, the book stresses the importance of combing textual and visual information a multimodal approach for effective retrieval. It provides the reader with clear ideas about information retrieval and its evaluation in contexts and domains such as healthcare, robot vision, press photography, and the Web.
A fine-grain asynchronous pipeline reaching the synchronous speed

In this paper we present a new handshake cell, which is used to construct a pipeline called Locally Distributed Asynchronous pipeline (LDA). The handshakes generate control signals, which form 4-phase signaling communication protocol. A 64-bit parity encoder designed using the LDA pipeline has shown to be faster than other asynchronous/synchronous implementations of the encoder.
THE EYEHARP: AN EYE-TRACKING-BASED MUSICAL INSTRUMENT

In this paper we present the EyeHarp, a new musical instrument based on eye tracking. The EyeHarp consists of a self-built low-cost eye-tracking device which communicates with an intuitive musical interface. The system allows performers and composers to produce music by controlling sound settings and musical events using eye movement. We describe the development of the EyeHarp, in particular the construction of the eye-tracking device and the design and implementation of the musical interface. We conduct a preliminary experiment for evaluating the system and report on the results.
Mechanistic modelling of blocking formation and decay

In the atmospheric mid-latitudes, upper-level jets exists which transport storms, generated through baroclinic instability, eastward across the oceans to the continental land masses. Under atmospheric blocking conditions, the normal passage of storms is interrupted by a region of high-pressure which remains lodged at the end of the storm tracks for periods of a week or more, causing the jet to split and the storms forced to pass around to the north and south, causing anomalous weather conditions over this high-pressure region. Being able to predict when these events occur, how long they will persist, and their eventual decay would be of value to improve weather prediction. This work looks at a simplified idealisation of this situation, with a view to improve understanding of any precursors to such events occurring, and their subsequent behaviour. A 2-layer, 3-plane, quasi-geostrophic channel model is used to examine the interactions between an upper-layer jet and high-frequency eddies supplied from a wavemaker in the lower layer. For certain initial jets, a dipole similar to an atmospheric block is formed, which remains stable to large-amplitude. By adding a shear to the upper-layer jet, a low-frequency vacillation cycle is induced, whereby the high-frequencies excite a split in the jet, which breaks down due to instability. This instability is demonstrated using a local instability analysis technique, and is also reflected in energy diagnostics. The role of the high-frequency eddies through the various phases of the cycle is also examined. A spherical-geometry model is also used with an aim to help bridge the gap between this highly-simplified model and the real atmosphere. These results suggest that the meridional shear in the upper-level atmospheric jetstream may determine whether blocking would develop, persist or breakdown. The structure of the upper-level jet could be controlled by seasonal variations or large-scale teleconnection patterns.
Single chip variable rate viterbi decoder of constraint length K = 5

This thesis presents a fully self-testable integrated circuit (IC) variable-rate Viterbi decoder of constraint length K = 5. The chip is designed to decode convolutional codes ranging from rate 7/8 to 1/4, derived from the same rate 1/2 mother code. The architecture of the Viterbi decoder is bit-serial node-parallel. The incoming 8-level quantized channel bits are input in parallel and converted to a serial stream. This reduces the amount of interprocessor wiring area substantially, as there are only single wire connections between the add-compare-select (ACS) units. High decoding speed is still achieved because the ACS operation is carried out concurrentiy in each of the 16 states. For the path memory, the register exchange technique was adopted. To reduce the ICs silicon area, the path memory is full-custom layout. For the trellis interconnections between consecutive memory stages, a novel state relabelling technique is proposed that reduces the interconnect area substantially. The area savings are accomplished by redrawing the trellis as sets of butterflies, A major aspect of this IC is its very cost effective built-in self-test. The stuck-at fault coverage is 99% with an overhead area of only 5%, which should not lower the manufacturing yield significantly, and thus yield significant benefits. A novel test algorithm was developed for the path memory. A specific but easy to generate test pattern is applied to the inputs. A major advantage of this deterministic test over pseudo-random techniques is that the test length is very short and, more importantly, independent of the number of states of the Viterbi decoder. The rest of the circuit is tested by pseudo-random patterns combined with a multiple signature analysis scheme. After finding an appropriate initial state of the test pattern generator, it is possible to check for four identical signatures. Compared to checking only one signature at the end of the test session, checking four identical signatures has the advantage of reducing the probability of error escape, while avoiding complicated signature checking for four different references. Moreover, test time can be reduced as faulty chips can be discarded as soon as a signature does not match the reference. These advantageous features are accomplished with circuit overhead equal to checking only a single signature at the end of the test session. The only cost is a one-time logic simulation performed at design phase.
Student Perception of Instruction Utilizing a Compressed Video Network

The delivery of instruction within education is going through a process of change at the presrnt time. One development that has had an impact on instruction delivery is interactive distance education. There are however, questions that need to be answered concerning the different components which are a part of this form of distance education. One such component relates to the attitudes of students who are receiving instruction through interactive distance education. It was the purpose of this study to ascertain student attitudes as they related to the different aspects of taking a course in this type of educational environment.
Programming in Algorithms : Generic Programming and its Implementation

The decisions which language designers make when implementing new features, and the e ects which those decisions have on a nished language, is a fascinating eld of study which has been largely overlooked by many programming language researchers. In this paper, we will explore the implementation of generic programming, a powerful programming technique, in four modern programming languages (C++, C#, Java, and Haskell). We discuss the process of designing each implementation and how those design choices a ect their use in each language. In doing so, we build a coherent theory of trade-o s in language design and how those trade-o s can be minimized.
Validity of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) screening for sepsis in surgical mortalities.

BACKGROUND Sepsis is among the leading causes of death in the United States. The Agency for Healthcare Research and Quality uses International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) billing code screening for the identification of sepsis. We investigated the incidence of sepsis in mortality at our academic medical center through ICD-9-CM screening of billing codes corresponding to sepsis and compared this approach for accuracy using physician chart review as the gold-standard. METHODS Two hundred forty-three surgical mortalities between January 2012 and January 2013 were reviewed by a Performance Improvement team. All mortalities were screened and evaluated for sepsis using physician chart review and ICD-9-CM codes for sepsis (995.91), severe sepsis (995.92), and septic shock (785.52). RESULTS Unexpected mortalities were associated with higher rates of sepsis and expected mortalities than anticipated (p<0.0001). A total of 40.6% of patients with sepsis suffered from more than one infection; the most common infectious sources were intra-abdominal (43.5%), blood stream (40.3%), and pulmonary (38.7%) infections. Screening by ICD-9-CM identified sepsis in 23.0% of mortalities, and physician review identified sepsis in 25.5% of mortalities. The sensitivity and specificity of ICD-9-CM screening were 82.3% and 78.3%, respectively. The positive and negative predictive values were 91.1% and 62.1%, respectively. CONCLUSION Sepsis is a common concurrent condition in surgical patients who die unexpectedly. Screening by ICD-9-CM for sepsis is accurate in identifying patients with sepsis but misses the identification of all patients with sepsis. The diagnostic accuracy of ICD-9-CM screening for sepsis is currently not adequate for public reporting or benchmarking, and is useful only as a guide for institutional quality improvement.
Modeling and Analysis of Noise and Interconnects for On-Chip Communication Link Design

This thesis considers modeling and analysis of noise and interconnects in onchip communication. Besides transistor count and speed, the capabilities of a modern design are often limited by on-chip communication links. These links typically consist of multiple interconnects that run parallel to each other for long distances between functional or memory blocks. Due to the scaling of technology, the interconnects have considerable electrical parasitics that affect their performance, power dissipation and signal integrity. Furthermore, because of electromagnetic coupling, the interconnects in the link need to be considered as an interacting group instead of as isolated signal paths. There is a need for accurate and computationally effective models in the early stages of the chip design process to assess or optimize issues affecting these interconnects. For this purpose, a set of analytical models is developed for on-chip data links in this thesis. First, a model is proposed for modeling crosstalk and intersymbol interference. The model takes into account the effects of inductance, initial states and bit sequences. Intersymbol interference is shown to affect crosstalk voltage and propagation delay depending on bus throughput and the amount of inductance. Next, a model is proposed for the switching current of a coupled bus. The model is combined with an existing model to evaluate power supply noise. The model is then applied to reduce both functional crosstalk and power supply noise caused by a bus as a trade-off with time. The proposed reduction method is shown to be effective in reducing long-range crosstalk noise. The effects of process variation on encoded signaling are then modeled. In encoded signaling, the input signals to a bus are encoded using additional signaling circuitry. The proposed model includes variation in both the signaling circuitry and in the wires to calculate the total delay variation of a bus. The model is applied to study level-encoded dual-rail and 1-of-4 signaling. In addition to regular voltage-mode and encoded voltage-mode signaling, current-mode signaling is a promising technique for global communication. A model for energy dissipation in RLC current-mode signaling is proposed in the thesis. The energy is derived separately for the driver, wire and receiver termination. The location where the energy is dissipated in current-mode signaling is shown to vary as a function of wire width. All proposed models in the thesis include inductive effects and they are verified with SPICE simulations.
Bluetooth Configuration of an FPGA: An Application to Modular Robotics

Self-reconfigurable modular robotics represents a new approach to robotic hardware. Instead of being designed as a huge centralized system, the “robot” is composed of many simple, identical, interacting modules. With the help of some computation, sensing and communication capabilities, self-reconfiguring robots should be able to adapt their morphology to the environment in order to fulfill a desired task. The Biologically Inspired Group (BIRG) of the Swiss Federal Institute of Technology in Lausanne (EPFL) has developed a brand new Modular Robot called YaMoR. Each module contains an FPGA, a Bluetooth board, a power board, two batteries and a servo-motor. Assembling the modules together, a centralized Java application can supervise the overall movement via Bluetooth. The aim of the current semester project is to study the unexploited programming potential of the Bluetooth board, containing an ARM core, some Flash and some SRAM. In particular, we show how we can configure the FPGA board wirelessly.
A TELL English Course to Meet the Needs of a Multilevel BA in ELT Group: What Was Wrong?.

A Technology Enhanced Language Learning (TELL) course was designed to meet the needs of a multilevel first-semester group of students of the BA in English Language Teaching (ELT) taught at the School of Languages of the Juarez University of the State of Durango (ELE-UJED), Mexico. Amongst the relevant needs, students were to reach a CEFR B1.1 level of English (out of two CEFR B1 sub-levels), notwithstanding their very different overall skill level of English. They also had to be immersed in active, student-centred learning approaches in spite of the wide diversity of language teaching approaches used in their 5-7 previous curricular English courses, or possible additional study in Mexico or abroad. After the results of diagnostic tests and self-assessment checklists, teams were integrated according to similar levels of command. Empirical research carried out throughout the course and a post-study survey demonstrated that the integration of collaborative learning and technology-enhanced language learning, including computer-based assessment and video clip outcomes, were very useful elements for reaching the course goals. However, it was also found out that the designed checklists for selfmonitoring of progress were not used by students on a regular basis, even though the survey reported that only a quarter of them considered checklists as not useful/not very useful for raising awareness of their lacks, weaknesses, and strengths.
Impacto económico del tratamiento con vitamina D en pacientes con enfermedad renal crónica

En los ultimos anos se esta reconociendo la importancia de las acciones extraesqueleticas de la actividad endocrina de la vitamina D y su profunda interaccion con la ERC. Ello ha facilitado el que se pueda disponer de muchos compuestos de vitamina D, tanto nutricional, como activa, con importantes diferencias en su coste economico. En esta revision se repasa la evidencia disponible sobre la utilidad de los distintos tipos de vitamina D, tanto nutricional como activa, en pacientes con enfermedad renal cronica, tanto en estadios 3-4 como en dialisis, con especial enfasis tanto en su utilidad para el control del hiperparatiroidismo como en su efecto sobre la morbimortalidad. Tambien se analizan los estudios farmacoeconomicos que se han publicado y que comparan entre si algunos metabolitos activos de la vitamina D. De esta revision puede concluirse que en el momento actual no existe todavia una base cientifica suficiente como para preferir la utilizacion de una vitamina D activa respecto a otra. Mientras no disponga de mas datos, el clinico debe seguir las recomendaciones de las guias de practica clinica, matizadas por la experiencia adquirida con sus pacientes y siempre teniendo en cuenta las implicaciones economicas de sus decisiones terapeuticas.
Photorealistic Surface Rendering with Microfacet Theory

Photorealistic rendering involves the numeric resolution of physically accurate light/matter interactions which, despite the tremendous and continuously increasing computational power that we now have at our disposal, is nowhere from becoming a quick and simple task for our computers. This is mainly due to the way that we represent objects: in order to reproduce the subtle interactions that create detail, tremendous amounts of geometry need to be queried. Hence, at render time, this complexity leads to heavy input/output operations which, combined with numerically complex filtering operators, require unreasonable amounts of computation times to guarantee artifact-free images. In order to alleviate such issues with today's constraints, a multiscale representation for matter must be derived. In this thesis, we derive such a representation for matter whose interface can be modelled as a displaced surface, a configuration that is typically simulated with displacement texture mapping in computer graphics. Our representation is derived within the realm of microfacet theory (a framework originally designed to model reflection of rough surfaces), which we review and augment in two respects. First, we render the theory applicable across multiple scales by extending it to support noncentral microfacet statistics. Second, we derive an inversion procedure that retrieves microfacet statistics from backscattering reflection evaluations. We show how this augmented framework may be applied to derive a general and efficient (although approximate) down-sampling operator for displacement texture maps that (a) preserves the anisotropy exhibited by light transport for any resolution, (b) can be applied prior to rendering and stored into MIP texture maps to drastically reduce the number of input/output operations, and (c) considerably simplifies per-pixel filtering operations, resulting overall in shorter rendering times. In order to validate and demonstrate the effectiveness of our operator, we render antialiased photorealistic images against ground truth. In addition, we provide C++ implementations all along the dissertation to facilitate the reproduction of the presented results. We conclude with a discussion on limitations of our approach, and avenues for a more general multiscale representation for matter.
