Carga de trabalho de enfermagem em unidades de terapia intensiva publicas e privadas

OBJECTIVE: This study sought to compare patients at public and private intensive care units according to the nursing workload and interventions provided. METHODS: This retrospective, comparative cohort study included 600 patients admitted to 4 intensive care units in Sao Paulo. The nursing workload and interventions were assessed using the Nursing Activities Score during the first and last 24 hours of the patient's stay at the intensive care unit. Pearson's chi-square test, Fisher's exact test, the Mann-Whitney test, and Student's t test were used to compare the patient groups. RESULTS: The average Nursing Activities Score upon admission to the intensive care unit was 61.9, with a score of 52.8 upon discharge. Significant differences were found among the patients at public and private intensive care units relative to the average Nursing Activities Score upon admission, as well as for 12 out of 23 nursing interventions performed during the first 24 hours of stay at the intensive care units. The patients at the public intensive care units exhibited a higher average score and overall more frequent nursing interventions, with the exception of those involved in the "care of drains", "mobilization and positioning", and "intravenous hyperalimentation". The groups also differed with regard to the evolution of the Nursing Activities Score among the total case series as well as the groups of survivors from the time of admission to discharge from the intensive care unit. CONCLUSION: Patients admitted to public and private intensive care units exhibit differences in their nursing care demands, which may help managers with nursing manpower planning.
ZOOM: A Performance-Energy Cache Simulator

On-chip cache sizes are growing with each generation of microprocessors in an attempt to bridge the ever-widening memory-processor performance gap. At the same time, energy dissipation in caches has become an important consideration due to increased integration and operating speeds and the explosive growth of battery-operated devices. These trends indicate that there is much to be gained from making energy and area, as well as performance, front-end design issues. This thesis presents ZOOM, a fast, flexible and robust framework for optimizing and characterizing the performance, energy and area of low-power caches in the early-stages of design. ZOOM consists of a timing-sensitive functional simulator and a micro-architecture simulator with HSPICE r © netlist generation capability. Preliminary evaluation indicates that the micro-architecture simulator estimates access time and energy to within 10% and 15%, respectively, of HSPICE simulated estimates for both SRAM and CAM-based caches.

Embedded Vision System for Autonomous Face Recognizer Robot using Eigenface Detector-PCA Improved Face Detection for Largely Occluded Faces

The problem is to propose a method for detecting the face and recognizing the face for a robot. This is a challenging problem because faces are non-rigid and have a high degree of variability in size, shape, colour, and texture. In this report, an embedded vision system is built to locate, recognize and track the faces. Three individual sub-systems are present. The first one is face detection based on Haar-like classifier and ViolaJones object detector. The second one is face recognition system based on Eigenface detector using principal component analysis method. The third one is face tracking based on Haar Cascade Classifier. For fast and an efficient embedded vision system for an autonomous robot, the software used is OpenCV library. The system developed has improved performance and can also detect largely occluded faces.
On the reliability of unreliable information: Gossip as cultural memory

When individuals learn from what others tell them, the information is subject to transmission error that does not arise in learning from direct experience. Yet evidence shows that humans consistently prefer this apparently more unreliable source of information. We examine the effect this preference has in cases where the information concerns a judgment on others’ behaviour and is used to establish cooperation in a society. We present a spatial model confirming that cooperation can be sustained by gossip containing a high degree of uncertainty. Accuracy alone does not predict the value of information in evolutionary terms; relevance, the impact of information on behavioural outcomes, must also be considered. We then show that once relevance is incorporated as a criterion, second-hand information can no longer be discounted on the basis of its poor fidelity alone. Finally we show that the relative importance of accuracy and relevance depends on factors of life history and demography.
MEDIUM ACCESS CONTROL PROTOCOLS FOR WIRELESS SENSOR NETWORKS: LITERATURE SURVEY

Wireless Sensor Networks (WSNs) have become an active research area for the researchers. Although sensor nodes have low processor, low memory and limited energy, they have capabilities with random located, self organizing, collective work, local computation. WSNs consist of this nodes. WSNs is feasibility in military, healty, environmental, home automotion and commercial applications. Various Medium Access Control (MAC) protocols with different objectives were proposed for WSNs. In this paper, we first outline the sensor network properties that are crucial for the design of MAC layer protocols. Then, we describe several MAC protocols proposed for sensor networks emphasizing their strengths and weakness. Also, we presented security problems and solutions on MAC protocol. Finally, we point out open research issues of MAC layer design.
A unified approach for FSM synthesis on FPGA architectures

We address the problem of finite state machines (FSM) synthesis for the two most popular Field Programmable Gate Array (FPGA) architectures : Actel and Xilinx. We propose a unified approach that deals with state assignment, optimization and mapping problems and that takes the target architecture into account during all the phases of the synthesis. This approach is made possible by very fast FPGA mapping techniques based on multi-ROBDD representation (Shared, Reduced and Ordered Binary Decision Diagrams). A prototype has been developed for FSM synthesis on Xilinx X3090 and Actel ACT1 architectures. Given a FSM description in VHDL or KISS format, it directly generates a look-up table (LUT) network for Xilinx or a multiplexor-based (MB) network for Actel. The results are promising and have been obtained within reasonable computing time. Comparisons have been made with the traditional approach implemented by Sis. <<ETX>>
Anwendungen des semantischen Wissens über Konzepte im Information Retrieval

Deutsch) Die im Folgenden beschriebenen experimentellen Arbeiten befassen sich mit der Integration des semantischen Wissens über Konzepte in das Information Retrieval (IR). Verschiedene Arten des Wissens werden aus dem lexikalisch-semantischen Wortnetz GermaNet extrahiert. Einerseits wurde geprüft, ob die Performanz eines IR-Systems durch eine Erweiterung der Anfrage mit Wörtern aus automatisch generierten Definitionen der Konzepte verbessert wird. Andererseits wurde ein neuartiges Information Retrieval Modell getestet, dem lexikalisch-semantische Verwandtschaft der Wörter zugrunde liegt. Die Ergebnisse aller Experimente wurden auf einem IR-Datensatz in der Domäne „Elektronische Berufsberatung“ mit einem herkömmlichen IR-System verglichen und automatisch ausgewertet. Dabei ergab sich: 1) eine Erweiterung der Anfragen durch Hyponyme ist besonders nützlich; 2) das semantische IR-Modell schneidet auf der gleichen Ebene ab, wie das tf*idf IR-Modell.
Waveform coding using time code multiplexing

A uniform amplitude sampler is presented as an alternative to uniform time-sampling systems. Time code multiplexing (TCM) consists of an encoder and a decoder. The encoder transmits the quantized time intervals corresponding to the time at which the input signal passed through uniformly spaced amplitude levels. The decoder reconstructs the signal by using a sin(x)/x convolution in the amplitude instead of time domain. Even though the channel bit stream is variable rate, TCM systems can be effectively used with the packet-switched voice/data networks of today's technology. The Nyquist rate which exists for the bandlimited uniform time-sampling systems has a parallel Nyquist rate for uniform amplitude-sampling systems. However, TCM offers the advantage of being able to change the input signal bandwidth and therefore the minimum required sampling rate, which is not easily accomplished with uniform time-sampling systems. TCM data results are discussed, showing SNR-versus-bit-rate performance. Audio recordings of computer simulations are presented for 8-, 16-, and 24-kbit/s systems. <<ETX>>

Reconfigurability of multi-star based lightwave LANs

One of the most crucial design issues in the multi-star-based lightwave LAN environment, the system reconfigurability, i.e., the system capability to reconfigure its virtual topology according to different traffic patterns, is discussed. New reconfiguration metrics are defined as functions of the system hardware parameters. A generic fiber assignment algorithm for achieving the maximum reconfigurable physical topology with minimized system cost is introduced. The system designer can use the introduced reconfigurability-hardware considerations for optimizing the system design. <<ETX>>
Utilisation of an adaptive resonance theory neural network as a genetic algorithm fitness evaluator

A novel method of genetic algorithm fitness evaluation, using adaptive resonance theory (ART) neural networks, is proposed. It is shown that a genetic algorithm can use an ART network to assign fitness measures. An ARTMAP network is proposed to control the cluster creation process. This fitness evaluation method is to be applied to an artificial musical composition system.
Information diffusion in online social networks

Online social networks play a major role in the spread of information at very large scale and it becomes essential to provide means to analyze this phenomenon. Analyzing information diffusion proves to be a challenging task since the raw data produced by users of these networks are a flood of ideas, recommendations, opinions, etc. The aim of this PhD work is to help in the understanding of this phenomenon. So far, our contributions are the following: (i) a survey of developments in the field; (ii) T-BaSIC, a graph-based model for information diffusion prediction; (iii) SONDY, an open source platform that helps understanding social network users' interests and activity by providing emerging topics and events detection as well as network analysis functionalities.
High-Level Control of Agent-based Crowds by means of General Constraints

The use of virtual crowds in visual eects has grown tremendously since the warring armies of virtual orcs and elves were seen in The Lord of the Rings. These crowds are generated by agent-based simulations, where each agent has the ability to reason and act for itself. This autonomy is eective at automatically producing realistic, complex group behaviour but leads to problems in controlling the crowds. Due to interaction between crowd members, the link between the behaviour of the individual and that of the whole crowd is not obvious. The control of a crowd's behaviour is, therefore, time consuming and frustrating, as manually editing the behaviour of individuals is often the only control approach available. This problem of control has not been widely addressed in crowd simulation research. We propose, implement and test a system in which a user may control the behaviour of a crowd by means of general constraints. This Constraint Satisfaction system automatically alters the behaviour of the individuals in the crowd such that the group behaviour meets the provided constraints. We test this system on a number of scenarios involving dierent types of agents and compare the effectiveness of this automatic system to an expert user manually changing the crowd. We find our method of control, in most cases, to be at least as effective as the expert user.
Implementation of an Algorithmic To Improve MCDS Based Routing In Mobile Ad-Hoc Network By Using Articulation Point

A virtual backbone can reduce the Communication Overhead, increase the Bandwidth Efficiency, reduce Channel Bandwidth Consumption, decrease Management. Thus virtual backbone is being employed to optimize the number and locations of the resource centers in a give Wireless Ad hoc network. Only virtual backbone situated nodes act as routers and thus other nodes need not to acquire, keep, or update routing information. Generally CDS concept is implemented as virtual backbone in Mobile Ad hoc network and it must be of Minimum Size. Algorithms to find CDS in Ad hoc networks is divided into two types of Centralized (Global) Algorithms and Decentralized (Local) Algorithms. we determine MCDS of a greph And Analysis the performance and result. The proposed algorithms for MCDS formation are analyzed that calculate the list of nodes as MCDS for the wireless ad hoc networks with pictorial representation.
Quantifying Losses in Power Systems Using Different Types of FACTS Controllers

This thesis discusses the placement of conventional power flow controllers (namely the Fixed series capacitor (FSC), Phase Angle Regulating Transformer (PAR)) and Flexible AC Transmission System (FACTS) devices (namely the Thyristor Controlled Series Capacitor (TCSC), the Static Synchronous Series Compensator (SSSC), the Unified Power Flow Controllers (UPFC) and the Sen Transformer (ST)) in bulk power systems to minimize transmission losses in the entire system. This firstly resolves line overloading and improves the overall voltage profile of the entire system. Secondly the transmission losses are minimized and also help in reducing the generation, which results in additional dollar savings in terms of the fuel costs. The sizes of the FACTS devices used were small in order to keep the initial installation costs low for the utility. The reduced FACTS device ratings are mentioned as a benefit, but not included in the overall loss minimization calculations. Various types of FACTS devices were modeled and placed in the power system, and the economic benefits were discussed and compared for different power flow conditions. The FSC, PAR, TCSC are the FACTS Devices commonly used in the electric utility industry. In addition to the previous devices the SSSC and UPFC were also modeled in the popular PSS/E and PSAT 3 softwares. The Sen Transformer was modeled using an electromagnetic transient simulation program (PSCAD/EMTDC). A line stability index was used to find the optimum location for placing the FACTS device. This thesis also provides a quantified value for the overall losses with the different FACTS devices, which is not available in the previous research literature.

Validation of the PAR-Q+ and ePARmed-X+

The Physical Activity Readiness Questionnaire for Everyone (PAR-Q+) and the electronic Physical Activity Readiness Medical Examination (ePARmed-X+) were created recently to reduce the barriers to physical activity participation for individuals with and without established chronic disease. Our primary purpose was to provide preliminary evidence on the effectiveness of these new forms for pre-participation screening and risk stratification. In particular, we sought to examine the new PAR-Q+ (and ePARmed-X+) risk stratification strategy in comparison to the previous PAR-Q. The new PAR-Q+ and ePARmed-X+ risk stratification and pre-participation strategy reduced significantly the number individuals that were sent for medical referral in comparison to the PAR-Q (i.e., 0.8% vs. 15%, respectively). The reliability of the PAR-Q+ over a three month period was high (r = 0.99). Moreover, the new strategy demonstrated high sensitivity (0.90 (95% CI = 0.77-0.96)) and specificity (1 (95% CI = 0.99-1)) for determining those with and without hypertension, respectively. In conclusion, our preliminary evaluation of the new PAR-Q+ and ePARmed-X+ risk stratification and pre-participation strategy in comparison to the PAR-Q reveals that the new process reduces greatly the barriers to physical activity participation, with a high reliability, sensitivity, and specificity of measurement.
Bagadus App: Notational data capture and instant video analysis using mobile devices

Enormous amounts of money and other resources are poured into professional soccer today. Teams will do anything to get a competitive advantage, including investing heavily in new technology for player development and analysis. In this thesis, we investigate and implement an instant analytical system that captures sports notational data and combines it with high-quality virtual view video from the Bagadus system, removing the manual labor of traditional video analysis. We present a multi-platform mobile application and a playback system, which together act as a state-of-the-art analytical tool providing soccer experts with the means of capturing annotations and immediately play back zoomable and pannable video on stadium big screens, computers and mobile devices. By controlling remote playback and drawing on video through the app, sports professionals can provide instant, video-backed analysis of interesting situations on the pitch to players, analysts or even spectators. We investigate how to best design, implement and combine these components into a Instant Replay Analytical Subsystem for the Bagadus project to create an automated way of viewing and controlling video based on annotations. We describe how the system is optimized in terms of performance, to achieve real-time video control and drawing; scalability, by minimizing network data and memory usage; and usability, through a user-tested interface optimized for accuracy and speed for notational data capture, as well as user customization based on roles and easy filtering of annotations. The system has been tested and adapted through real life scenarios at Alfheim Stadium for Tromsø Idrettslag (TIL) and at Ullevaal Stadion for the Norway national football team.
SBR image approach for radio wave propagation in tunnels with and without traffic

We propose a deterministic approach to model the radio propagation channels in tunnels with and without traffic. This technique applies the modified shooting and bouncing ray (SBR) method to find equivalent sources (images) in each launched ray tube and sums the receiving complex amplitude contributed by all images coherently. In addition, the vector effective antenna height (VEH) is introduced to consider the polarization-coupling effect resulting from the shape of the tunnels. We verify this approach by comparing the numerical results in two canonical examples where closed-form solutions exist. The good agreement indicates that our method can provide a good approximation of high-frequency radio propagation inside tunnels where reflection is dominant. We show that the propagation loss in tunnels can vary considerably according to the tunnel shapes and the traffic inside them. From the results we also find a "focusing" effect, which makes the power received in an arched tunnel higher than that in a rectangular tunnel. Besides, the deep fading that appears in a rectangular tunnel is absent in an arched tunnel. The major effect of the traffic is observed to be the fast fading due to the reflection/obstruction of vehicles. Additional considerations, such as time delay, wall roughness, and wedge diffraction of radio wave propagation in tunnels are left for future studies.
Etiology and management of sexual dysfunction

Sexual dysfunction is the impairment or disruption of any of the three phases of normal sexual functioning, including loss of libido, impairment of physiological arousal and loss, delay or alteration of orgasm. Each one of these can be affected by an orchestra of factors like senility, medical and surgical illnesses, medications and drugs of abuse. Non-pharmacological therapy is the main stay in the treatment of sexual dysfunction and drugs are used as adjuncts for a quicker and better result. Management in many of the cases depends on the primary cause. Here is a review of the major etiological factors of sexual dysfunction and its management
Expression of p53 in imprint smears of endometrial carcinoma

The aims of this study were to determine the expression of p53 protein in endometrial adenocarcinomas (as a potential prognostic indicator before treatment) as well as normal endometrium in imprint smears and to correlate the results with clinicopathologic parameters of primary untreated endometrial cancer patients. Two hundred fifty five patients were evaluated with endometrial imprint cytology during a 29‐month period. Endometrial samples freshly resected from women who underwent total abdominal hysterectomy were studied. One hundred twenty six patients had endometrial carcinoma and 129 cases were diagnosed as normal endometrium. The expression of p53 was assessed by immunocytochemistry. Positive staining was correlated with increased surgical‐pathological stage, histological grade and lymph node metastases. High expression of p53 staining was significantly more frequent in histological type II than type I endometrial adenocarcinoma. High‐grade endometrial carcinoma had higher proportions and stronger intensity compared with low‐grade carcinoma. Negative immunostain for p53 protein was found in proliferative, secretory, and atrophic endometrium.
A new CELP speech coder for wireless communication

A new variable bit rate code excited linear predictive (CELP) coder of average bit rate around 4.2 kb/s is presented. The new coder is based on the federal standard FS 1016 CELP coder. Two main differences between this new coder and the FS 1016 coder are introduced. These two modifications will result in reducing the bit rate by about 0.53 kbits/s. A performance comparison between the proposed coder and other two coders is presented.
