Implementation of a differential aging measurement and compensation system for OLED panel

This paper presents a real-time aging measurement and feasible compensation system for the prolonged lifetime of OLED panel. The proposed system is composed of four parts, a PC with a man-machine interface, a measurement block, an adaptive amplifier block, and a compensation block. We apply a tree algorithm for less complexity and convenience of measurement on the degree of aging. An adaptive multi-stage differential amplifier is also implemented to deal with a various range of input voltages at the same spot.
A hospital-based prospective study on analysis of axis deviation in patients with first attck of anterior wall myocardial infarction

Background and Aim: Electrocardiography is a very important investigative procedure that can be performed easily and quickly. A baseline investigation in the evaluation of cardiac status, one practical application of electrocardiogram, is axis determination, which is very useful in diagnosis and prognostication in patients with acute coronary syndromes. Therefore, the aim of this study is to calculate the mean QRS axis using the hexaxial reference frame in patients with the first acute myocardial infarction (MI) and to see if any relation exists between the axis deviation and the clinical outcome. Methods: It is a hospital-based cross-sectional study conducted in 200 patients with the first attack of anterior wall MI with respect to a control group consisting 162 normal subjects. The mean frontal plane QRS axis was found using the hexaxial reference frame. Student's t-test and Pearson Chi-square test were used for statistical analysis of data. Results: Twenty-five percent of the study subjects had left axis deviation, and 3.5% had right axis deviation. About 15% of the subjects developed left ventricular failure (LVF), of whom 19 (63%) were males and 11 (37%) were females. This difference between males and females was found to be statistically significant. The frequency of occurrence of LVF in females >61 years of age and that of arrhythmias in females 41–50 years was significantly higher. Conclusion: The statistically significant difference between the mean electrical axis (MEA) of the study subjects when compared with the controls is not unexpected as MI produces deviation of the MEA. There was a tendency for a greater axis shift (30°) in patients who developed LVF; however, this shift was not found to be statistically significant.
A robust fuzzy local Information c-means clustering algorithm with noise detection

Fuzzy c-means clustering (FCM), especially with spatial constraints (FCM_S), is an effective algorithm suitable for image segmentation. Its reliability contributes not only to the presentation of fuzziness for belongingness of every pixel but also to exploitation of spatial contextual information. But these algorithms still remain some problems when processing the image with noise, they are sensitive to the parameters which have to be tuned according to prior knowledge of the noise. In this paper, we propose a new FCM algorithm, combining the gray constraints and spatial constraints, called spatial and gray-level denoised fuzzy c-means (SGDFCM) algorithm. This new algorithm conquers the parameter disadvantages mentioned above by considering the possibility of noise of each pixel, which aims to improve the robustness and obtain more detail information. Furthermore, the possibility of noise can be calculated in advance, which means the algorithm is effective and efficient.

An MQTT-Based Context-Aware Autonomous System in oneM2M Architecture

Having a seamless connection between independently developed platforms has recently become an important issue. In addition, research is underway on autoconfiguration to minimize human interference while configuring devices for users to utilize Internet of Things (IoT) applications. OneM2M is a standardization group established to develop a standard Internet service platform. In the oneM2M environment, data exchange between each component is performed through HTTP, constrained application protocol (CoAP), and message queuing telemetry transport (MQTT). MQTT enables efficient data transmission in low-power and unreliable networks. However, MQTT is not suitable for service discovery for autoconfiguration given that it does not support multicasting and resource directories for managing IoT resources. In this paper, we present an architecture to provide an autoconfiguration mechanism by using the MQTT publish/subscribe messaging pattern. To realize fully autonomous systems, the proposed system autonomously interacts with devices by recognizing the context using semantic Web technology. We verify the feasibility of the proposed system through its implementation in the real environment. It is confirmed that the proposed approach is able to automatically configure MQTT-based devices and provide context-aware services using a standard interface.
CODE DENSITY OPTOMIZATION AND IMPLEMENTATION USING LZW APPROACH BASED ON 32-BIT RISC PROCESSOR

Considering the worldwide used of mobile to connect internet, and code compression technology that played significant role in saving space and power. Our study is focusing on how many items will be stored in the dictionary and how many bits long for every item, which will determine the optimum dictionary size to the compression process . Focusing on the dictionary size, one can gain the key for improving the compression ratio on interesting Benchmark. The results will hold on variant size of Benchmarks to investigate the proper dictionary size for variant cases. The average result of compression ratio was 62.34% for a dictionary with 9 bits code and 256 items, where the maximum value of compression ratio was 72.89%. If we use another dictionary with more than 10 bits, the compression ratio will vary a little.
A better physical environment in the workplace means higher well-being? A study with healthcare professionals

Abstract Physical working conditions have potential effects on health, and play an important role in quality of life, and job satisfaction, yet most studies on the direct or indirect consequences of physical environmental conditions on healthcare professionals' focus on outcomes such as performance, efficiency, and error. The objective of this study was to analyze the effects of the physical environment quality of healthcare settings on professionals' well-being. The sample comprised 148 healthcare professionals working in inpatient or outpatient care units from four different hospitals. Two independent variables were used: Objective environmental quality (high/low) and Type of care unit (inpatient/outpatient); and three well-being indicators were analyzed: Job satisfaction, Perception of the care unit as close to an ideal care unit, and Subjective stress. Results show that healthcare professionals working in hospitals with better physical conditions feel more satisfied with their job, and perceive the care unit as closer to the ideal. Stress levels were not affected by physical environment quality or the type of care unit.
A Priority-based Routing Algorithm for Underwater Wireless Sensor Networks (UWSNs)

Advances in low-power electronics design and wireless communication have enabled the development of low cost, low power micro-sensor nodes. These sensor nodes are capable of sensing, processing and forwarding which have many applications such as underwater networks. In underwater wireless sensor networks (UWSNs) applications, sensors which are placed in underwater environments and predicted enable applications in oceanographic data collection, mine reconnaissance, pollution, assisted navigation, distributed tactical surveillance, and ocean sampling. Each sensor uses acoustic signals as its physical medium for communications. This study focuses on a priority-based routing protocol in underwater wireless sensor networks. This routing method tries to improve the QOS requirements with considering high and low priority traffic classes. Through simulation study using the OPNET simulator, we proved that proposed algorithm achieves high performance as compared to GEDAR, in terms of packet loss, end to end delay of data transmission and energy consumption.
Children's Reading of Printed Text and Hypertext with Navigation Overviews: The Role of Comprehension, Sustained Attention, and Visuo-Spatial Abilities

Hypertexts include new structural features, such as navigable graphical overviews, that dramatically change the way students interact with texts. Nevertheless, at school students traditionally practice literacy skills appropriate for reading and comprehending printed texts. We explored the possibility that those skills might not be the same as the ones required to master hypertext reading. Specifically, we tested the hypothesis that hypertext structural features, such as navigable graphical overviews, might scaffold students with low comprehension and sustained-attention abilities, but demand higher involvement of visuo-spatial skills. Results from a group of 6th-grade students only partially supported the hypertext structural hypothesis: while students with low sustained-attention abilities scored higher on questions demanding the integration of information in the hypertext version, the impact of comprehension and visuo-spatial abilities on performance did not differ between text types. Finally, we discuss the theoretical and potential instructional applications of the results.
Cooperative RSS-Based Localization in Wireless Sensor Networks Using Relative Error Estimation and Semidefinite Programming

A new cooperative received signal strength-based localization algorithm is proposed which employs relative error estimation and semidefinite programming (SDP). First, the log-normal shadowing RSS measurement model is transformed into an equivalent multiplicative model. Then, a relative error estimation criterion is used with this model to develop a nonconvex estimator to approximate the maximum likelihood solution. Finally, semidefinite relaxation is applied to the nonconvex estimator to obtain an SDP estimator. The proposed algorithm is first derived for noncooperative RSS-based localization and then extended to the cooperative case. The Cramer–Rao lower bound is derived for cooperative RSS-based localization. Performance results are presented, which demonstrate that the proposed SDP estimator provides a significant improvement over existing localization methods.
Quantization of a Low-Density Parity-Check (LDPC) Decoder: Limited-Precision Digital Design of the Sum-Product Algorithm (SPA) for Wireless Voice and Video Communication Channels

of the Dissertation Quantization of a Low-Density Parity-Check (LDPC) Decoder: Limited-Precision Digital Design of the Sum-Product Algorithm (SPA) for Wireless Voice and Video Communication Channels. by Raymond B Moberly Claremont Graduate University and San Diego State University: 2012 This dissertation presents two-bit and three-bit quantizations for Sum Product Algorithm (SPA) decoding of Low-Density Parity-Check (LDPC) codes. The study involves evaluation of both decoding performance and hardware implementation requirements. Trade-o s between these factors are considered. The quantizations are simulated in software to measure decoding performance. While quantization e ects are the focal point of the research, a comparison of the number of decoding iterations and of the number of bits of precision used in the decoder are both presented along with the quantization experiments. Decoder performance, measured in terms of both Bit Error Rate (BER) and Frame Error Rate (FER), is tested for each two-bit and three-bit quantization over a range of Signal to Noise Ratio (SNR) values. No single quantization outperforms all other quantizations for the entire tested SNR range. Analysis of the SPA is performed, revealing strategies for computational e ciency and digital design. The hardware designs combine the parity-check and variable-node update steps of the SPA into a single update computation. The update computation is implemented in a hardware design language (HDL), synthesized to programmable logic, and then tested on a Field Programmable Gate Array (FPGA). Hardware implementation requirements, as measured from the synthesis results, are evaluated and compared to a selection of other published works, particularly the work of Planjery et al. A exible implementation is proposed that can adapt the quantization as the channel conditions change.

A Framework for the Object-Oriented Design and Simulation of Information System Dynamics

A framework for the object-oriented (00) design and simulation of information system (IS) dynamics is proposed, supported by an object-oriented simulation (OOS) mapping tool and a prototype object-oriented integrated development environment (OOIDE). The objective is to make the design and simulation of IS design dynamics a common and integral part of the 00 systems development process by implementing the framework within an integrated and computer-aided systems development environment. The framework proposes a series of steps to follow for the developer who has decided to look at the dynamics of an information system's (IS) logical design and is using an 00 methodology for the development of the new system. The use of the framework, the OOS mapping tool and the prototype OOIDE are validated using an existing IS.
Unraveling Glucocorticoid Resistance In MLLrearranged Infant Acute Lymphoblastic Leukemia

markdownabstract__Abstract__ In the Netherlands, approximately 650 children aged between 0 and 18 years are diagnosed with cancer every year, including ~120 patients suffering from leukemia. Leukemia (Greek for leukos - white, and haima for blood) is a type of cancer characterized by an abnormal increase of immature (non-functional) white blood cells in the bone marrow. As a result, the production of all healthy, functional blood cells is impaired, leading to anemia (loss of functional red blood cells), infections (loss of functional white blood cells) and (internal) bleeding (loss of functional platelets), and eventually to leukemic infiltration of other tissues such as liver, spleen, skin and in some instances even in the central nervous system. Depending on the rate of disease progression, leukemia is classified into “acute” (rapidly developing) or “chronic” (slowly developing). Acute leukemias are usually characterized by uncontrolled proliferation of highly immature (leukemic) white blood cells, whereas chronic leukemias more often involve the malignant transformation of more differentiated white blood cells. Leukemia can further be classified into lymphoid (B-cell or T-cell leukemias) or non-lymphoid (myeloid) types of leukemia, depending on the type of white blood cell that was subjected to leukemic transformation.
Implementation of a combustion model based on the flamelet concept and its application to turbulent reactive sprays

El objetivo principal de este trabajo es la modelizacion del proceso de combustion turbulenta de chorros diesel, incluyendo el evento de autoencendido y la estructura de la llama cuasi-estacionaria. Para este fin, se implementa un modelo de combustion basado en el concepto de flamelets en un entorno RANS en la plataforma CFD OpenFOAM. El enfoque de modelado aplicado aqui sigue la idea de un modelo del tipo flamelets no-estacionarias/variable de progreso (UFPV). En estos modelos, la hipotesis subyacente es que se asume que la estructura de una llama turbulenta puede ser representada por un conjunto de llamas de difusion laminares (flamelets). Se han estudiado soluciones de encendido y apagado de estas llamas en configuracion de flujo opuesto. La fraccion de mezcla Z, la tasa de disipacion escalar ? y la variable de progreso Yc son parametros clave en la descripcion de tales llamas no-estacionarias. La transicion de la mezcla desde el estado inerte hasta el estado reactivo estable esta descrita univocamente por Yc . Ademas se estudia un metodo interesante para calcular llamas de difusion aproximadas (ADF) con el objetivo de reducir el coste computacional especialmente para combustibles complejos. La interaccion sub-malla de turbulencia-quimica esta tomada en cuenta por medio de modelado de PDF presumido, de forma que se asume la distribucion estadistica conjunta de la fraccion de mezcla, la tasa de disipacion escalar estequiometrica y la variable de progreso. El resultado de esta operacion a priori se almacena en una base de datos de flamelets turbulentas. Para obtener las propiedades termoquimicas de esta base de datos durante un calculo, se requieren cuatro parametros de busqueda: la media de la fraccion de mezcla y su varianza, la media de la tasa de disipacion escalar estequiometrica y la media de la variable de progreso. Ademas, se presentan dos diferentes formas de acoplamiento entre el modelo de combustion y el codigo CFD. En primer lugar, el modelo se ha aplicado al experimento de la llama turbulenta despegada de H2/N2 de la Universidad de Berkeley. Esta llama de laboratorio es un caso de prueba ampliamente utilizado en el area de modelado de combustion turbulenta. Los resultados obtenidos representan un buen acuerdo entre la simulacion y los experimentos. Por otra parte, la version simplificada del modelo de combustion basado en soluciones ADF tambien se ha aplicado con exito y se han obtenido resultados alentadores. Finalmente, el modelo simplificado de combustion se aplica al "Spray H" del Engine Combustion Network (ECN). El tiempo de retraso y la longitud de despegue calculados se comparan con los datos experimentales. Tambien se estudia la influencia de temperatura ambiente sobre estos dos parametros caracteristicos de llama. Ademas, se analiza con detalle la estructura de la llama cuasi-estacionaria, la prediccion de las tasas de liberacion de calor y las fracciones masicas de las especies.
Optimization Techniques for Modern Power Systems Planning, Operation and Control

Recent developments in computing, communication and improvements in optimization techniques have piqued interest in improving the current operational practices and in addressing the challenges of future power grids. This dissertation leverages these new developments for improved quasi-static analysis of power systems for applications in power system planning, operation and control. The premise of much of the work presented in this dissertation centers around development of better mathematical modeling for optimization problems which are then used to solve current and future challenges of power grid. To this end, the models developed in this research work contributes to the area of renewable integration, demand response, power grid resilience and constrained contiguous and non-contiguous partitioning of power networks. The emphasis of this dissertation is on finding solutions to system operator level problems in real-time. For instance, multi-period mixed integer linear programming problem for applications in demand response schemes involving more than million variables are solved to optimality in less than 20 seconds of computation time through tighter formulation. A balanced, constrained, contiguous partitioning scheme capable of partitioning 20,000 bus power system in under one minute is developed for use in time sensitive application area such as controlled islanding.
