Behavioral analysis of malicious code through network traffic and system call monitoring

Malicious code (malware) that spreads through the Internet-such as viruses, worms and trojans-is a major threat to information security nowadays and a profitable business for criminals. There are several approaches to analyze malware by monitoring its actions while it is running in a controlled environment, which helps to identify malicious behaviors. In this article we propose a tool to analyze malware behavior in a non-intrusive and effective way, extending the analysis possibilities to cover malware samples that bypass current approaches and also fixes some issues with these approaches.
Beyond elocution: Multimodal narrative discourse analysis of L2 storytelling

Abstract Drawing upon research on narrative and speech styles and on digital and multimodal communication, the author proposes multimodal narrative discourse analysis (MNDA) with associated pedagogical and analytical procedures to teach and study storytelling. The second language (L2) students first participated in multimodal narrative simulations in the virtual world of Second Life. The university students then presented, evaluated, and revised stories in both face-to-face and digital contexts through multiple modalities and technologies. MNDA further provided tools and methods for analyzing the students’ discursive processes and agentive experiences of L2 storytelling. The results of MNDA showed that the proper use of narrative elements, discourse structures, and stylistic devices, as well as bodily, visual, and video resources, assisted the students in developing multimodal designs and storytelling styles. This technology-mediated discourse approach to L2 storytelling suggests the importance of teaching and researching broader narrative contexts and activities other than simply elocution in multimodal communicative activities.
Misperceptions of Feedback in a Dynamic Decision Making Experiment

Studies in the psychology of individual choice have identified numerous cognitive and other bounds on human rationality, often producing systematic errors and biases. Yet for the most part models of aggregate phenomena in management science and economics are not consistent with such micro-empirical knowledge of individual decision-making. One explanation has been the difficulty of extending the experimental methods used to study individual decisions to aggregate, dynamic settings. This paper reports an experiment on the generation of macrodynamics from microstructure in a common managerial context. Subjects manage a simulated inventory distribution system which contains multiple actors, feedbacks, nonlinearities, and time delays. The interaction of individual decisions with the structure of the simulated firm produces aggregate dynamics which systematically diverge from optimal behavior. An anchoring and adjustment heuristic for stock management is proposed as a model of the subjects' decision processes. Econometric tests show the rule explains the subjects' behavior well. The estimation results identify several `misperceptions of feedback' which account for the poor performance of the subjects. In particular, subjects are shown to be insensitive to the feedbacks from their decisions to the environment. Finally, the generality of the results is considered and implications for behavioral theories of aggregate social and economic dynamics are explored.
Continuous speech recognition using large vocabulary word spotting and CV syllable spotting

A continuous-speech recognition system for Japanese text input is described. The system is speaker dependent and recognizes continuous phrasal speech. A consonant-vowel (CV) concatenation syllable lattice and a word lattice are generated from input speech using a vector-quantization-based continuous DP matching technique. These lattices are converted into Japanese written form using a word dictionary and grammatical information. Two methods for acoustic processing are proposed: a large vocabulary word spotting technique using high-frequency words and an optimization method for adjusting CV templates to a speaker by maximizing recognition accuracy. In recognition experiments, 500 words were selected as word templates, covering more than 90% of the technical words in reports written about X-ray computer tomography scanning. 1000 CV syllables were generated using these words. A word spotting accuracy of more than 70% and a CV spotting accuracy of 72% were obtained after iterative training. The CV spotting accuracy was improved by about 10% through iterative training. <<ETX>>
Riau Heritage Digital Library sebagai Sarana Informasi dan Inventaris Warisan Budaya Nusantara berbasis Web

Riau memiliki warisan budaya dan warisan alam yang banyak dan beragam yang tersebar disepanjang hamparan wilayah provinsi Riau.

Energy Efficient Reconfigurable MAC Protocol for Underwater Acoustic Sensor Network

In a multi-hop Underwater Acoustic Sensor Network (UWASN) the challenges of the medium access control (MAC) are different than that of single hop fully connected network. Existing MAC solutions try to solve the challenges of MAC control by channel reservation or contention elimination techniques. These techniques heavily depend on the transmissions of control packets that result in large overhead specially in terms of energy consumptions. In this thesis, a multi-hop enabled energy efficient MAC protocol for UWASN is proposed by exploiting a novel 2-phase contention resolution technique that minimizes the usage of control packets by utilizing short duration tones. A probabilistic model of the proposed protocol is also developed to analyze the performance of the protocol analytically. A network simulation framework has been designed to simulate MAC and a physical layer for UWASN. The proposed MAC protocol has been evaluated through quantitative analysis and simulation. By evaluating this proposed protocol through quantitative analysis and simulation, this research found that the proposed protocol outperforms in terms of energy efficiency, channel utilization and end-to-end delay. The proposed protocol achieves stable throughput and a maximum 30% of theoretical maximum channel utilization in high traffic load in comparison to the existing protocol that becomes unstable and does not perform well. Additionally, the proposed protocol achieves better energy efficiency and lower end-to-end delay.
Compressed Sensing (CS) Imaging with Wide FOV and Dynamic Magnification

Abstract : In this project we developed imaging systems based on the principles of compressive sensing. We developed advanced signal processing algorithms as well as a hardware testbed. The key idea in CS reconstruction is the realization that most signals encountered in practice are sparse in some domain and the theory of CS exploits such sparsity to dictate that far fewer sampling resources than traditional approaches are needed. Spectral image cubes are particularly well suited for sparse representation as images across different wavelengths exhibit strong correlation. We have thus developed a testbed to acquire and reconstruct natural images from a limited number of linear projection measurements at sub-Nyquist sampling rates. A key to the success of CS is the design of the measurement ensemble, which is based on the evaluation of the incoherence between the measurement ensemble and the sparsity basis. Due to the large scale nature of images, the generation of the measurement ensemble should be both computationally efficient and memory efficient. Based on these principles, we developed compressive cross-sectional imaging (confocal) systems, a single pixel compressive camera, and a multispectral imaging system. Advanced algorithms for the efficient reconstruction of the compressive measurements were developed.

Métodos de censo para la obtención de los parámetros reproductores del urogallo Tetrao urogallus aquitanus en los Pirineos : Comparacion y recomendaciones para su aplicacion

En partant des donnees obtenues lors de six annees consecutives d'etude en trois endroits differents de la chaine pyreneenne, le succes de reproduction (S.R. = nombre de poussins pour la totalite des poules) du Grand Tetras a ete etabli en suivant deux methodologies decrites dans la bibliographie. Nous avons verifie la validite des methodologies et la surface minimum utilisee pour le comptage ainsi que le nombre de contacts necessaires pour stabiliser le S.R. mentionne ci-dessus. Nous avons trouve que le route-census donnait une sous-estimation des resultats pendant les annees de bonne reproduction (SR > 1). L'utilisation de chiens d'arret est la methode la plus fiable et la plus efficace pour obtenir plusieurs parametres reproducteurs. Pour la stabilisation du SR et la surface de l'echantillon, nous avons remarque les elements suivants. Lors des annees de mauvaise reproduction (BS 1), il faut contacter un nombre plus eleve de femelles et augmenter la surface de l'echantillon. Plusieurs considerations pratiques sur l'application du route-census sont presentees dans le texte.
Impact of Sodium Ingestion During Exercise on Endurance Performance: A Systematic Review

Sports nutrition guidelines frequently encourage sodium ingestion during endurance exercise, and much work has been undertaken to quantify sweat sodium losses during exercise. However, current guidelines for sodium do not recommend specific quantities, nor provide justification for the effectiveness of sodium to improve endurance performance. A systematic review was undertaken using six databases (CINAHL, Embase, Medline Ovid, Scopus, SPORTDiscus, and Web of Science) to determine the effect of sodium ingestion during exercise on endurance performance. Five studies met the inclusion criteria. They varied in quantity of sodium consumed (280 to 900mg/h), ingestion method (capsules or solutions), fluid intake (programmed or ad libitum) and performance outcomes (time trial, distance-test, time to exhaustion following steady state exercise, and finish time in an organized competition). Only one study reported a significant benefit from sodium ingestion (504mg/h) of 7.8%. All other studies found no significant effect of sodium on performance. Several limitations were found, including different ambient conditions across study days, ad libitum carbohydrate intake that was not reported, and performance measured during an organized competition where other factors may have influenced finish time. No study measured performance in hot ambient conditions (e.g., ≥30°C), and no study quantified each participant’s sweat sodium losses beforehand, thus providing sodium intake as a proportion of expected losses. It is concluded that there is currently minimal evidence that sodium ingestion during exercise improves endurance performance. The limited number and quality of existing studies indicates a need for future work in this area.
An integrative method for video based traffic parameter extraction in ITS

In this paper, an effective integrative method that takes advantages of background subtraction and edge detection is proposed for vehicle detection and shadow rejection. Based on the method, vehicle counting, tracking, classification, and speed estimation for multi-lanes are achieved so that real-time traffic parameters can be obtained to describe the load of each lane.
Prediction of Hypertension Complications Risk Using Classification Techniques

Chronic diseases including hypertension and its complications are major sources causing the national medical expenditures to increase. We aim to predict the risk of hypertension complications for hypertension patients, using the sample national healthcare database established by Korean National Health Insurance Corporation. We apply classification techniques, such as logistic regression, linear discriminant analysis, and classification and regression tree to predict the hypertension complication onset event for each patient. The performance of these three methods is compared in terms of accuracy, sensitivity and specificity. The result shows that these methods seem to perform similarly although the logistic regression performs marginally better than the others.
Motion control of omni-directional type walking support system "Walking Helper"

In this paper, we develop a prototype of an intelligent walking support system referred to as walking helper and propose a motion control algorithm for it. Walking Helper consists of an omni-directional mobile base, a body force sensor, a support frame and a cover around the mobile base. By using the omni-directional mobile base and body force sensor, the good maneuverability and the high safety of walking helper are realized. In addition, we propose a motion control algorithm referred to as adaptive caster action to utilize walking helper effectively in an environment such as a home, an office, a hospital, etc. The proposed control algorithm is experimentally applied to the developed walking helper, and the validity of the proposed control algorithm is illustrated by the experimental results.
Physical Therapists' Perception of Risk of Violating Laws and Rules Governing the Practice of Physical Therapy and/or Their Personal Moral and Ethical Values When Failing to Provide Treatment for an Uninsured or Underinsured Patient

Patrick D. Pauken, Advisor There will be times when physical therapists will be asked to treat patients who cannot afford needed services. Under such circumstances, physical therapists are at serious risk of violating the laws and rules governing their profession and also, perhaps, at risk of violating their personal moral or ethical values if they fail to treat, or arrange alternative treatment for, these patients. The purpose of this study was to examine the relationship between two independent variables, (1) Professional role of the physical therapist (clinician, administrator, or educator), and (2) APTA membership status, and two dependent variables, (1) perceived level of risk of violating the laws and rules governing the practice of physical therapy in Ohio, if treatment is not provided to, or arranged for, the patient in a case dilemma, and (2) perceived risk of violating personal moral or ethical values in the same situation. This study utilized a questionnaire that asked respondents to rate perception of risk of violating the dependent variables in each of four defined resolutions to the dilemma of treating an uninsured or underinsured patient. These resolutions were (A) fail to provide, or arrange for, treatment, (B) refer the patient to a safety-net provider, (C) provide some, but not all, necessary treatments or, (D) make illegal adjustment(s) to billing. APTA members reported a higher perceived risk than non-APTA members of being out of compliance with the laws and rules governing physical therapy in Ohio if they resolved the dilemma by providing some forms of treatment, which were more affordable or were covered by the patient's insurance plan, not providing other services, which although needed, are
Natural history of Hodgkin's disease as related to staging

Since the natural history of untreated Hodgkin's disease cannot be determined by the few case reports in the literature, a study has been made based on the wider experience recorded in the case histories of the patients registered in a large radiotherapy center. An analysis of 323 successive patients treated at the Ontario Cancer Institute, Toronto, who have been followed more than 10 years has revealed at least 2 different patterns in the course of Hodgkin's disease—one potentially curable, the other not yet fully understood. These 2 forms usually can be identified at the time of diagnosis. When this is possible more adequate radiotherapy can be prescribed. The finding of 2 separate clinical courses fits in with the epidemiological concept of 2 different populations in Hodgkin's disease which have been identified by studies in age incidence.
Overcoming barriers to health service access and influencing the demand side through purchasing

This paper investigates the role of demand-side barriers in impeding access to the use of health services. Demand-side barriers are defined as determinants of use of health care that are not dependent on service delivery or price or direct price of those services. They include distance, education, opportunity cost, and cultural and social barriers. There is some evidence that these barriers are at least as important in determining access to services as the quality, volume, and price of services delivered by health care providers. The paper is divided into two sections. In the first section literature on demand barriers to accessing services is reviewed. Since the literature on these barriers is so substantial, the review is restricted to an illustrative survey of the main barriers in low-, middle-, and high-income countries. The second section surveys studies that report and evaluate methods for overcoming these barriers. The literature here is substantially less voluminous even when gray and unpublished sources are included in the survey. Many of the studies relate to access to obstetrical and family planning care. In most cases evaluation is not rigorous, and it is often hard to separate the impact of the intervention itself from other confounding factors. Few of the studies reported have an explicit poverty focus, although many of the interventions are conducted in poor areas. There is a clear need for further work to examine the most cost effective ways of reducing barriers to accessing services and in particular to investigate what methods are most effective in expanding access to essential care among the poor.
