Abnormality Detection in a Landing Operation Using Hidden Markov Model

The air transport industry is seeking to manage risks in air travels. Its main objective is to detect abnormal behaviors in various flight conditions. The current methods have some limitations and are based on studying the risks and measuring the effective parameters. These parameters do not remove the dependency of a flight process on the time and human decisions. In this paper, we used an HMM-based method which is among the main methods of situation assessment in data fusion. This method includes two clustering levels based on data and model. The experiments were conducted with B_777 flight data and the variables considered in the next generation of ADS_B. According to the results of this study, our method has high speed and sensitivity in detection of abnormal changes which are effective in the flight parameters when landing. With the dynamic modelling, there is no dependency on time and conditions. The adaptation of this method to other air traffic control systems makes its extension possible to cover all flight conditions.
No . TR-1989-G 21 , 28 December 1989 1 Computer algebra and symbolic computational mechanics

Although, undoubtedly, numerical computations are the computations of primary importance in computational mechanics, nevertheless, symbolic computations also constitute a significant related tool. Here at first an extensive review of the major computer algebra systems is made, i.e. (in alphabetical order) of Derive, Macsyma, Maple, Mathematica and Reduce. Next, several applications of symbolic computations to computational mechanics are mentioned in brief (including the computer algebra system used in each of them) as well as the related very recent research results by the author. Extensive conclusions with respect to the usefulness of computer algebra systems in computational mechanics are also mentioned and several comments concerning the trends and the possibilities in this very interesting application of computer algebra systems are made.
Conforming Stokes Elements Yielding Divergence-Free Approximations on Quadrilateral Meshes

In this dissertation, we propose conforming finite element methods that yield divergence-free velocity approximations for the steady Stokes problem on cubical and quadrilateral meshes. In the first part, we construct the finite element spaces for the two-dimensional problem on rectangular grids. Then in the second part, we extend these spaces to n-dimensional spaces. We use discrete differential forms and smooth de Rham complexes to verify the stability and the conformity of the proposed methods, and the solenoidality of the velocity approximations. In the third part, we shift our focus from a dimensionwise extension to a meshwise improvement by introducing macro elements on general shape-regular quadrilateral meshes. By utilizing a smooth de Rham complex, we prove that the macro finite element method yields divergence-free velocity solutions, and with the construction of a Fortin operator, we validate the stability of the method. To improve the pressure approximation properties, we compute a post-processed pressure solution locally. In addition, we describe the implementation process of the (velocity) macro finite element. We show that the methods developed in this dissertation yield optimal convergence rates and present numerical experiments which are supportive of the theoretical results. Moreover, we provide experimental results of our method for the Navier-Stokes equations and show that the convergence rates are preserved.
A Presence-Absence Survey to Monitor Montezuma Quail in Western Texas

Developing an effective monitoring program for Montezuma quail (Cyrtonyx montezumae) is challenging because the technique must be practical for surveying vast, remote landscapes while accounting for the species’ low detectability. We used call-back surveys within a presence–absence framework to estimate occupancy and detection probability of Montezuma quail and used this information in conjunction with habitat data to develop an estimated probability of occurrence map for the species. We established survey points at 4 sites in western Texas (n1⁄4 20–30 points/site) and conducted 5 repeat surveys/season during June–August 2007 and 2008. We documented abiotic conditions (temperature, time of day, survey number, and year) during surveys and quantified microhabitat (% bare ground, food-plant density, vegetation height, and visual obstruction) and macrohabitat (vegetation type, elevation, aspect, and slope) at survey points. We then used an informationtheoretic approach to evaluate the influence of microand macro-habitat on detection probability and occupancy at a local and regional scale, respectively. At a microhabitat scale, the most parsimonious model (DAICc ,2; Nagelkerke’s R 1⁄40.46) suggested detection probability was influenced primarily by year (bYear1⁄40.91, 95% CI1⁄40.24–1.57), with occupancy being influenced primarily (but minimally) by year (bYear1⁄4 59.7, 95% CI1⁄4 179.0–59.6) and vegetation-height (bVH1⁄4 67.7, 95% CI1⁄4 71.9–207.4). This model indicated that detection probability decreased from 2007 (0.40; 95% CI1⁄4 0.31–0.49) to 2008 (0.21; 95% CI1⁄4 0.14–0.32), as did occupancy (1.00 vs. 0.72, respectively), which corresponded to a transition from a relatively wet to dry year. At a macrohabitat scale, the most parsimonious model (DAICc ,2; Nagelkerke’s R1⁄4 0.20) suggested occupancy was influenced by elevation (bElevation1⁄4 1.11 6 0.56) and vegetation type (bVegetation type 21⁄4 3.17 6 1.26; bVegetation type 31⁄4 1.20 6 1.18), and we used these variables to construct a first-approximation, probability of occupancy map. Given our findings, presence–absence surveys may be a viable approach for monitoring Montezuma quail populations through time, and use of a probability of occupancy map can help with efficient allocation of survey points and effort. However, the viability of using a presence–absence approach to monitor Montezuma quail populations will depend on whether sampling effort can be increased sufficiently to obtain more precise estimates of occupancy. In addition, our probability of occupancy map should be regarded as a first approximation and further research should be conducted to refine the relationships. Citation: Sanders, C. G. , F.

Hand Detection Using HSV Model

Natural Human Computer Interaction (HCI) is the demand of today’s technology oriented world. Detecting and tracking of face and hands are important for gesture recognition. Skin detection is a very popular and useful technique for detecting and tracking human-body parts. It has been much attention mainly because of its vast range of applications such as, face detection and tracking, naked people detection, hand detection and tracking, people retrieval in databases and Internet, etc. Many models and algorithms are being used for detection of face, hand and its gesture. Hand detection using model or classification is to build a decision rule that will discriminate between skin and non-skin pixels. Identifying skin color pixels involves finding the range of values for which most skin pixels would fall in a given color space. All external factors will be eliminated to detect the hand and its color in the image in complex background. Keywords: image segmentation, hand detection, hci, computer vision, RGB, HSV
The design and evaluation of an interface for teleoperation through eye gaze (TeleGaze)

Most teleoperation tasks involve controlling as well as monitoring from a remote location. This requires the eyes of the operator to be engaged in the monitoring task and the hands in the controlling task for the whole duration of the operation. Since the eyes are involved in the monitoring task anyway, inputs from their gaze can be used to aid in the controlling task to free the hands of the operator from this task. However, the challenge here lies in distinguishing between the inputs that should be used for monitoring and those that should be used for controlling. To address this challenge, this paper presents a novel means of developing a teleoperation interface through eye gaze. The interface developed in this work, which is called the TeleGaze interface for short, enables the operator to monitor as well as control a mobile robot remotely through the use of the eyes only. The TeleGaze interface is developed out of two different designs based on user satisfaction. A task oriented evaluation for the TeleGaze interface is conducted in comparison with other interaction modalities. The evaluation shows promising results towards TeleGaze as an aid in human-robot interaction
LTCC packaging for Lab-on-a-chip application

This work presents design, manufacturing and testing of new packaging method for Lab-on-a-chip (LOC) application. Packaging was made for silicon microchip which can measure cell adhesion on chips surface as indication of cell viability. Reliability testing was done with daisy-chain resistance measurement in real conditions. Moreover basic theory of LTCC and Lab-on-a-chip technology is presented. Resilient LTCC technology was used for packaging material and conductive/insulating epoxies were applied for electrical contacts and barriers against the environment. It is fundamentally important to develop new packaging methods for LOC applications, so all the properties can be utilized reliably. Packaging was tested under the cell growth conditions and the package showed to withstand all these challenges. Moreover the presented packaging method is possible to use also in other Lab-on-achip applications.
Informal and formal meaning of the norm and the institution

In this article the problem of estimation the performance of formal norm is examined. To this purpose the existing definitions of the notion “norm” are analyzed and summarized, their insufficient formalization is noted, whereupon with the approach, using the apparatus of theory of sets and Boolean algebra, a strict definition of the norm, which includes static and dynamic components, is proposed. The description of the norm is extended by the definition of the space of the norm – a group of notions related to the norm. It’s substantiated that these notions shouldn’t be regarded as component parts of the norm. The methods of estimation the endogenous performance of formal norm (rule), basing on an analysis of its internal characteristics, but not on the results of its application is proposed. It’s suggested to determine the quality of the norm at three ways: norm as itself; accordance of the new norm to current ones; easiness of its compliance and easiness of its control. This approach allows identifying potential problematic points of the norm that can lead to difficulties in the future. Using the proposed methods of estimation of formal norm in areas, where such norms are developed actively (e.g. jurisprudence), can increase the quality of projectable norms, thus reducing costs for their future support. For the already existing norms those methods allow determining their weaknesses. In the theoretical-economic research the apparatus of formalization of norms may be useful in examination of institutional dynamics – namely, the process of institutional change.

UAV MONITORING FOR ENVIROMENTAL MANAGEMENT IN GALAPAGOS ISLANDS

Abstract. In the Galapagos Islands, where 97% of the territory is protected and ecosystem dynamics are highly vulnerable, timely and accurate information is key for decision making. An appropriate monitoring system must meet two key features: on one hand, being able to capture information in a systematic and regular basis, and on the other hand, to quickly gather information on demand for specific purposes. The lack of such a system for geographic information limits the ability of Galapagos Islands’ institutions to evaluate and act upon environmental threats such as invasive species spread and vegetation degradation. In this context, the use of UAVs (unmanned aerial vehicles) for capturing georeferenced images is a promising technology for environmental monitoring and management. This paper explores the potential of UAV images for monitoring degradation of littoral vegetation in Puerto Villamil (Isabela Island, Galapagos, Ecuador). Imagery was captured using two camera types: Red Green Blue (RGB) and Infrarred Red Green (NIR). First, vegetation presence was identified through NDVI. Second, object-based classification was carried out for characterization of vegetation vigor. Results demonstrates the feasibility of UAV technology for base-line studies and monitoring on the amount and vigorousness of littoral vegetation in the Galapagos Islands. It is also showed that UAV images are not only useful for visual interpretation and object delineation, but also to timely produce useful thematic information for environmental management.
The Effects of Brand Relationship Quality on the Participation of the Consumer to Boycott

Commitment is a pillar of the consumer-brand relationship. It is often presented as the will of a customer to continue the relationship with its brand. Although this relational current is very studied by researchers, there remains still little developed. Thus, the literature did not examine the combination of commitment-boycott. This thesis aims on the one hand to the development of the theoretical framework for the quality of the relationship with the brand and also to improve understanding of the role of the perceived egregiousness between quality of the relationship and the boycott decision. The final survey shows that an effect of assimilation occurs and the consumer will have the intention to continue the relation when the gravity committed by the brand is of an economic nature. However, a contrast effect is released when the perceived gravity is qualified ethical where the commitment of the consumer will maximize this serious act and consequently, he will be ready to participate in a boycott action.
An Optimized Prediction Model Based on Feature Probability for Functional Identification of Large-Scale Ubiquitous Data

Recently, there is a growing interest in the sequence analysis. In particular, the next generation sequencing (NGS) technique fragments the base sequence and analyzes the functions thereof. Its essential role is to arrange pieces of the base sequence together based on sequencing and to define the functions. The organization of unarranged piece of sequence is one of the active research areas; moreover, definition of gene function automatically is a popular research topic. The previous studies about the automatic gene function have mainly utilized the method that automatically defines protein functions by using the similarities of base sequence or the disclosed database and the protein interaction or context free method. This study aims to predict the category of protein whose function was not defined after learning automatically with GO by extracting the characteristics of protein inside the cluster. This study conducts clustering by using the protein interaction that is generated by the similarities of base sequence under the assumption that the proteins inside the cluster have similar function. The proposed method is to show an optimized result in accordance with the option after finding the option value that can give the outperformed prediction of GO, which classifies the functions based on the IPR and keywords inside the same cluster as the unique features.
MESPEUS: a database of the geometry of metal sites in proteins

A database with details of the geometry of metal sites in proteins has been set up. The data are derived from metalloprotein structures that are in the Protein Data Bank [PDB; Berman, Henrick, Nakamura & Markley (2006). Nucleic Acids Res. 35, D301–D303] and have been determined at 2.5 A resolution or better. The database contains all contacts within the crystal asymmetric unit considered to be chemical bonds to any of the metals Na, Mg, K, Ca, Mn, Fe, Co, Ni, Cu or Zn. The stored information includes PDB code, crystal data, resolution of structure determination, refinement program and R factor, protein class (from PDB header), contact distances, atom names of metal and interacting atoms as they appear in the PDB, site occupancies, B values, coordination numbers, information on coordination shapes, and metal–metal distances. This may be accessed by SQL queries, or by a user-friendly web interface which searches for contacts between specified types of atoms [for example Ca and carboxylate O of aspartate, Co and imidazole Nδ of histidine] or which delivers details of all the metal sites in a specified protein. The web interface allows graphical display of the metal site, on its own or within the whole protein molecule, and may be accessed at http://eduliss.bch. ed.ac. uk/MESPEUS/. Some applications are briefly described, including a study of the characteristics of Mg sites that bind adenosine triphosphate, the derivation of an average Mg—Ophosphate distance and some problems that arise when average bond distances with high precision are required.

This paper has become imperative in view of the on-going Federal Government’s initiative in charting an ethical roadmap for Nigeria. Ethics permeates all aspects of our national life and human resource management profession is no exception. Ethics refers to the principle of conduct governing an individual or a group. This paper examines ethical HRM practices in work organisations in Nigeria and the roles of HR professionals in promoting ethical practices with a view to achieving employee well-being, satisfaction at work and organisational performance. Based on theoretical and practical insights, the authors x-ray an array of unethical human resource management practices in work organisations in Nigeria. To combat unethical HR practices in the workplace, the authors enjoin HR professionals in line with top management to put in place ethical policies and codes and to constantly embark on ethical training of workers at all level as well as the institutionalisation of whistle blowing policy in their organisations. Keywords: Ethics, Human Resource Management, Work Organisation, HR Professionals.
How Do Companies In The Energy Sector Invite Stakeholder Engagement Through CSR Communication Strategies

Corporate social responsibility has become an urgent topic nowadays. Following multiple ecological scandals involving huge energy conglomerates, society has started to ask private sector difficult questions: do you care about anything outside your direct commercial aims? Do you have any idea about moral duties and social problems? What really stands behind each of your controversial actions? Companies found themselves in the position when the absence of response is a global failure in terms of brand trust, brand equity and brand reputation. Their motives and communication styles will be assessed and analyzed through interpretive inductive content analysis of CSR reports. The author of this study attempts to look at this relationship through the lens of relatively new stakeholder theory developed by R.E. Freeman and assess what is really going on in the corporate sector. By assessing annual corporate sustainability reports the following fundamental questions will be addressed: (1) how do companies frame their motivation to engage stakeholders and (2) what are specific CSR communication strategies currently used by organizations, notably towards local communities? In general, this paper builds on existing ideas concerning the topic as well as attempts to fill in certain theoretical gaps for future research and managerial application.
Trace metals in liver and kidney of the franciscana ( Pontoporia blainvillei ) from the northern coast of Rio de Janeiro State, Brazil

In the Southwestern Atlantic few studies have documented trace metal concentrations in cetacean tissues. This study presents both hepatic and renal trace metal concentrations (Fe, Cu, Zn, Mn, Hg and Cd), in franciscana (n=17), inhabiting the waters of Rio de Janeiro State, southeastern Brazil. The concentrations of Fe, Cu, Zn, Mn and Hg generally were highest in the liver and Cd levels in liver and kidney were comparable. Hepatic and renal essential metal (Fe, Cu, Zn and Mn) concentrations were similar to those documented elsewhere for other species. THg and Cd concentrations were found to increase with age. The low concentrations of trace metals determined in the franciscana tissues in this study reflect its dietary habits, trophic position and the low bioavailability of metals in northern Rio de Janeiro.
Theory of Near-Field Scanning with a Probe Array

Abstract : In near-field scanning, as the electrical size of a device under test increases, it becomes increasingly time-consuming to collect all the required near-field samples using a single probe. Thus, it becomes desirable to use an array of probes to collect the near-field samples simultaneously to decrease the measurement time. We consider some of the electromagnetic issues associated with performing near-field measurement using an array of probes for antenna and bistatic radar cross section (RCS) applications.
