This paper presents a brief exposition of some of the basic concepts of system theory and sketches its principal problems and techniques. The discussion centers on the notion of state and state-space methods. Among the problems touched upon are those of characterization and identification, optimal control and system equivalence.
Receiver Architectures for MIMO-OFDM Based on a Combined VMP-SP Algorithm

Iterative information processing, either based on heurist ics or analytical frameworks, has been shown to be a very powerful tool for the design of efficient, yet feas ible, wireless receiver architectures. Within this context, algorithms performing message-passing on a p robabilistic graph, such as the sum-product (SP) and variational message passing (VMP) algorithms, hav e become increasingly popular. In this contribution, we apply a combined VMP-SP message-pa ssing technique to the design of receivers for MIMO-ODFM systems. The message-passing equa tions of the combined scheme can be obtained from the equations of the stationary points of a c onstrained region-based free energy approximation. When applied to a MIMO-OFDM probabilistic m odel, we obtain a generic receiver architecture performing iterative channel weight and nois e precision estimation, equalization and data decoding. We show that this generic scheme can be particular ized to a variety of different receiver structures, ranging from high-performance iterative stru ctures to low complexity receivers. This allows for a flexible design of the signal processing specially tail ored for the requirements of each specific application. The numerical assessment of our solutions, ba sed on Monte Carlo simulations, corroborates the high performance of the proposed algorithms and their su periority to heuristic approaches.

The utilization of this data can lead to a set of new applications, but also assist in different areas, such as recommendations, big data analysis, context-aware applications and the Internet of Things. In this challenge paper, we introduce this open research area presenting the motivation behind it and the relevant open issues with regard to searching over this data.
ANÁLISIS DE VARIABLES AGROMETEOROLÓGICAS EN NOCHES DE HELADAS UTILIZANDO MAPAS AUTO ORGANIZADOS Y ALGORITMOS DE INDUCCION

Las leyes clásicas del movimiento de los fluidos gobiernan el estado de la atmósfera. Los estados atmosféricos exhiben correlaciones en varias escala s espaciales y temporales. El diagnóstico de tales es tado procura capturar la dinámica de varias variables atmosféricas (como la temperatura y la presión) y e xplicar que procesos físicos influyen en el comportamiento. Así un sistema meteorológico se puede pensar como un sistema complejo cuyos componentes interactúan en varias escalas espaciales y temporales. Los enfoque s estadísticos a la predicción del tiempo incluyen di stintos enfoques (Wilks, 1995; Santhanam y Patra, 2001). L os sistemas inteligentes aparecen como alternativas út iles a las técnicas de modelado estadístico tradicional en muchas disciplinas científicas (Haykin, 1994). Revisando l as aplicaciones de redes neurales en las ciencias atmosféricas, Gardner y Dorling (1998) concluyen qu e las redes neurales dan generalmente resultados tan buen os o mejores que los métodos lineales. Hasta ahora, se h a enfocado la atención en combinar los métodos lineal es con redes neurales u otros tipos de sistemas inteligent es para aumentar el poder de este último. Esta tendencia co ntinúa hoy con enfoques más nuevos basados en algoritmos d e aprendizaje (Hsieh y Tan, 1998; Monahan, 2000). El término minería inteligente de datos [Evangelos & H an, 1996), es la aplicación de los métodos de aprendiza je automático [Michalski et al., 1983) al proceso no t rivial de extraer y presentar el conocimiento implícito, prev iamente desconocido, potencialmente útil y comprensible, a partir de grandes conjuntos de datos, con el objeto de pre deci tendencias automatizadas y comportamientos; y para describir de forma automatizada modelos previamente desconocidos, (Perichinsky & García-Martínez, 2000; ) implicando el uso de técnicas y herramientas de aprendizaje automático (machine learning). El Valle Superior del Negro de Río en Argentina es una de las regiones más importantes en la produc ción de frutas y vegetales del país. Comprende los valles inferiores de los ríos Limay y Neuquén y el valle s uperior del río del Negro. Las heladas tardías ocurren cuán do los árboles son sensibles a bajas temperaturas y tienen u impacto significativo en la producción regional. El análisis de serie cronológica de la temperatura del aire, la presión atmosférica, y la velocidad y dirección del viento involucran grandes cantidades de datos y la minería de datos podría ser una alternativa a métodos tradicio nales estadísticos para encontrar los grupos con señales estables.
Windows for Transform Processing

This report examines the time windows used in processing of signals in a transformed domain. The goal of windowing is to create frames of data, each of which will be used to calculate a transformed sequence. The transform coefficients are then modified (filtering for instance for noise reduction) or coded (transform coding). The modified transform coefficients are then applied to an inverse transform and windowed again before creating an output signal using addition of the overlapped blocks. It is the analysis window (before the transform) and the synthesis window (after the inverse transform) that are examined in this report. The requirement for perfect reconstruction (when the transform coefficients are not modified) is developed. This gives a condition on the product of the analysis and synthesis windows. An argument is given to show that if additive noise is introduced in the transform domain, the windowing should be equally apportioned between these windows, i.e. the analysis and synthesis windows should be the same. The windowing requirements for systems implementing block-by-block filtering of the input signal in the transform domain are also examined.

Ultrasound Guided Biopsy By Free Hand Technique And Its Usefulness *

Focal liver lesions are one of the most common findings detected in day to day practice. Ultrasound, now a day, has become first choice of investigation for screening of patients with suspected liver diseases as Focal liver lesions mainly comprise of liver abscess, cystic lesions, primary malignant neoplasm metastases, focal fatty infiltrations and hematoma. Due to non-specific signs and symptoms of such lesions and having limitations in diagnosing these lesions by biochemical tests, real-time ultrasonography has been proven as one of the most economical and accurate modality in diagnosis of focal liver lesions. It gives valuable information regarding specific parameters such as site, size, number of lesions, nature of lesions and relation to surrounding structures. Ultrasound is the most suitable imaging modality for biopsy of the liver in terms of versatility, ability to image in real-time, decreased cost, portability and absence of ionizing radiation [1]. This article examines ultrasound-guided liver biopsy, and describes the process involved in Free Hand liver biopsy technique, stressing the advantages of ultrasound in these biopsy procedures.

Reservation-Based Scheduling for Automotive DSMS under High Overload Condition

Recent automotive systems require various data, including data from on-board sensors and external sources to recognize environmental conditions. As the amount of sensor data used in automotive systems increases, processes that use such data become increasingly complicated. In addition, similar data processing can be duplicated over multiple applications. To address these issues, a data stream management system (DSMS) for automotive systems based on a data integration architecture has been developed. However, hard real-time deadlines cannot be guaranteed due to unpredictable load changes caused by data streams. For example, the arrival time and CPU utilization requested by data streams from vehicle-to-vehicle communications change rapidly depending on environmental conditions. We propose the reservation-based operator path earliest deadline first (ROP-EDF) scheduling algorithm for an automotive DSMS under overload conditions. The proposed algorithm reserves processor time preferentially for hard real-time tasks so that tasks can meet deadlines under overload conditions. ROP-EDF can be used for load testing on a single processor system. Experimental results show the effectiveness of the proposed algorithm compared with existing algorithms relative to the deadline miss ratio under overload conditions.
Kalman filter tuning for digital protection applications

This paper addresses the problem of tuning Kalman filters so that they can properly track signal fluctuations in digital relaying applications. The role of each parameter involved in the filter is discussed and adequate values are presented. Particular attention is paid to the covariance matrix of the model error, which is determinant for the filter adaptive capability.
ff ect of Senescence Phenotypes and Nitrate Availability on Wheat Leaf Metabolome during Grain Filling

The capacity for optimising grain yield depends largely on the timing of senescence and the processes underlying efficient remobilisation and cycling of nutrients from source tissues to the developing grain. This study describes how metabolism is adjusted during senescence in response to varying nitrogen application rates after anthesis. A comprehensive metabolite analysis was performed in field-grown Avalon/Cadenza using segregating doubled haploid wheat genotypes having contrasting traits relating to timing of the onset of senescence. Correlative matrices of metabolites and yield parameters determined the metabolic networks that underlie these phenotypes, and were helpful for identifying unique metabolites that are indicative of timing of senescence. They also revealed robust correlations between steady increases in hexose levels, a late senescence phenotype and high straw yield associated with low N fertiliser levels. Tryptophan, cis-aconitate, phosphate and 1-kestose demonstrated strong perturbations in response to nitrogen availability and progression towards developmental senescence. A comprehensive metabolic map of wheat leaf primary metabolites yielded a cumulative readout of processes that occur during developmental ripening and contribute to grain filling in plants with differential senescence timing.

CEOs ' Multicultural Experience , Firm Networks and Performance : Evidence from Firm-to-firm Transaction Data in Japan

This paper postulates a hypothesis that, the more diverse background a firm CEO has, the more extended firmto-firm networks the firm constructs, which in turns leads to higher firm performance. Using the firm level data of firm CEOs’ background and firm-to-firm networks, this paper corroborates the hypothesis by showing that the firms whose CEOs are non-local-born are more likely to have more extended firm-to-firm transaction networks and consequently have better firm performance. Aside from this main finding, it also finds that the CEOs’ graduated schools’ level in terms of difficulty of entrance exams, which we consider as a proxy for CEOs’ innate ability has a strong positive nexus with the firm performance. The finding suggests an importance of human resource mobilization for growth.

Test and Evaluation of Sensor Platforms in the AEDC Space Sensor Test Chambers

The space simulation test chambers at the Arnold Engineering Development Center (AEDC) offer a means of performing high-quality, economical, and timely state-of-the-art test and evaluation (T&E) to satisfy a variety of space system testing requirements. These requirements include sensor and focal plane array level characterization (including radiometric calibration and characterization and goniometric evaluation) and mission simulation. Such a ground test capability is crucial for reducing system development risk by testing the latest technologies developed for space-based, interceptor, and airborne sensor platforms. In response to the evolving requirements for testing sensor platforms, AEDC continues to develop new methodologies and techniques to maintain a suite of facilities capable of testing sensor systems at any level of development. This involves the integration of high-fidelity, complex, and dynamic scene projection systems in conjunction with comprehensive analysis and measurement of the properties of the optical systems. This paper describes the AEDC methodology for space sensor T&E, including uncertainty methodology and enhancements that are currently planned for the space sensor test facility.
CYCLIC RESPONSE OF A NEW STEEL-CONCRETE COMPOSITE FRAME SYSTEM

This paper introduces a new steel-concrete hybrid frame system. The frame system consists of steel tubed reinforced concrete columns and ordinary reinforced concrete beams with headed bars. The steel tubed reinforced concrete column is an ordinary reinforced concrete columns, however, transversely, it is reinforced with a thin steel tube. The steel tube provides shear resistance, confines the whole concrete cross section, and serves as stay-in-place formwork. In beams, the headed bars are intended to relocate the potential plastic hinge region away from the face of the beam-column joint. Two full-scale steel tubed columns, and two full scale beams with and without headed bars were experimentally investigated. Test results showed that headed bars were effective in moving plastic hinge regions away from the face of the column, however, more research is needed to examine the shear strength of concrete section in plastic hinge region with headed bars. Steel tubed columns investigated in this study exhibited high ductility and energy dissipation when subjected to large lateral displacements, and constant axial loads up to 0.36 Agfc’.
Hyperbaric oxygen treatment promotes antioxidative effects on rats with acute carbon monoxide poisoning via NF-E 2-related factor 2 activation

Oxidative stress plays an important role in brain injuries after carbon monoxide (CO) poisoning. The aim of this study was to investigate the antioxidative effects of hyperbaric oxygen (HBO) treatment on rats with acute CO poisoning and elucidate underlying mechanisms associated with this event. Sprague-Dawley male rats were subjected to CO poisoning and HBO treatment. Their cognitive function was tested to show the effects of CO poisoning and HBO treatment. Antioxidative effects were investigated by determination of antioxidant enzymes. Expression of NF-E2-related factor 2 (Nrf2) and its cytoplasm binding protein kelch-like ECH-associated protein 1 (Keap1) was evaluated by immunohistochemical staining and Western blot. Additionally, Nrf2 transfer into nuclear and combination with ARE were assessed by Western blot and Electrophoretic Mobility Shift Assay (EMSA). Results showed that HBO treatment increased levels of T-AOC, T-SOD, CuZnSOD, GPx, GR, and CAT, decreased by CO poisoning, and decreased MDA that had been increased by CO poisoning. Nrf2 disassociated from Keap1 in cytoplasm and transferred into nuclear to combine with ARE in the brains of HBO-treated CO-poisoned rats. These results suggest that HBO treatment increased antioxidant enzymes via the Nrf2-Keap1-ARE pathway. Therefore, Nrf2-mediated antioxidative effects may be one of the cellular mechanisms responsible for HBO treatment of brain injuries after acute CO poisoning.
Comparison of effectiveness of acceptance commitment therapy and metacognitive therapy on reducing symptoms, psychological capital and quality of life of patients suffering from irritable bowel syndrome

Background: The aim of the present study was to compare effectiveness of metacognitive therapy (MCT) and acceptance commitment therapy (ACT) on reducing syndromes, psychological capital and quality of life of patients suffering from irritable bowel syndrome (IBS). Materials and methods: Research method was quasi-experimental with pre-test, posttest, three-month follow-up and control group. Statistical population was all 20-40 years old females suffering from IBS who applied to Counseling Center of Pharmaceutical Sciences University located in Tehran City. Through available sampling, 45 patients were selected and assigned randomly in experimental group 1 (MCT), experimental group 2 (ACT) and control group (15 in each group). The Psychological Capital Inventory (Luthans, 1992) and Quality of Life Inventory (Ware & Sherbourne, 1992) were administered pre-test, posttest and follow-up period. The therapeutic packages of acceptance, commitment therapy and metacognitive therapy applied on experimental groups for eight 90minute sessions once a week. Control group was placed in a waiting list. Results: Both therapeutic methods equally increased psychological capital and quality of life in patients suffering from IBS. According to physicians’ report and own patients themselves, the symptoms of the disease were significantly reduced. Threemonth follow-up confirmed these results. Conclusion: Since psychosocial factors, in addition to biological elements, influence on severity of IBS symptoms, improving healthy quality of life and psychological capital indicators should be paid attention to prevent and treat this disorder.
ANTICIPATION MECHANISM AND INFLUENCE OF FATIGUE IN MEDIOLATERAL STABILOGRAM

INTRODUCTION An important feature of the Central Nervous System (CNS) is its capability to foreseeing future movements of the body [1]. This control does not act by feedback and is named anticipation. Several investigators have focused anticipation by studying the synergism between anti-gravitational muscles and the ones responsible for limbs movements [2]. Others report that anticipation can be affected by fatigue [3]. This study aims to detect the anticipation mechanism and the latency between the gastrocnemius muscle myoelectric signal and the mediolateral (x) stabilogram during static posture and test the fatigue influence.
Determination of hand-transmitted vibration risk on the human

Objective: The purpose of this paper is to examine the effectiveness of the proposed consideration for handtransmitted vibration measurement on the human. Method: To obtain the temporary threshold shift (TTS) in the fingertip vibrotactile perception threshold, the vibrotactile perception thresholds were measured before and after the subjects were exposed to hand-transmitted vibration from the hand-held tool. The vibration magnitude has been measured by using conventional vibration measurement on the tool and by using the proposed consideration vibration on the human simultaneously. Results: The proposed hand-transmitted vibration measurement on the subject was proportional with increasing TTS. In contrast the data from conventional vibration measurement on the tool shows a relatively constant vibration level while TTS increases within a subject group. Conclusion: The proposed measurement method of hand-transmitted vibration on the subject captures at least some of the effects of factors relating to the human interaction with the tool identified within Annex D of the ISO 5349-1 standard. The effectiveness of the proposed hand-transmitted vibration measurement consideration on the human for improved understanding of tool vibration exposure has been shown.
