Title of the Paper: Recent Developments in Social Media Mining

 

Authors: Peter Wlodarczak, Jeffrey Soar, Mustafa Ally

Pages: 364-370

Abstract: Mining the Web has become a very active area of research. It has gained in importance not only for academia but also for companies since users use the Web to share opinions, ideas and concerns on many subjects and extracting this information can reveal peoples motivations, behavioral patterns and intents. Companies have realized the potential of Web mining for detecting new trends, for getting user opinions on their products and services and for finding new business opportunities. In recent years Social Media such as Facebook and Twitter has been used since it facilitated the publishing and distribution of user generated content. For the first time in history we have now an unprecedented amount of opinionated data that is publicly accessible from anywhere in the world. Analyzing Social Media has been used among other for targeted marketing, opinion mining and has the potential to change the way companies do business. However, Social Media mining is challenging since it has to extract contextual information from human generated content. It has to analyze the meaning, syntax, sentiment polarity of natural language. Social Media mining is in the area of cognitive computing. Cognitive computing systems differ from traditional computing systems since they cannot use preconfigured rules and programs. That is why often Machine Learning techniques are used for Social Media analysis. They have the capability to learn from data and adapt to new problems and domains. This paper describes the state of the art techniques that have been used in recent research and proposes and approach for Social Media mining based on Machine Learning methods.


Title of the Paper: Helicopter Pitch Control System

 

Authors: Nenad Popovich, Christian R. Bonaobra

Pages: 357-363

Abstract: The helicopter was subjected to a few different optimization methods such as Root Locus, Ziegler-Nichols Tuning method, Systematic Trial Tuning method and Integral Absolute Error criteria. These are essential to find the “optimal’ gain(s) of a controller. This paper is focused on creating a system that can provide reliable pitch altitude control while being cost effective under outside disturbances. In order to have outstanding controller for our helicopter pitch control system, controller needs to have a stable response, low overshoot, together with a fast response, which means a quick settling time. We also kept in mind that we need to protect its mechanical components.

Authors: W. Velasquez, A. Munoz-Arcentales, M. Chalen T., Joaquın Salvachua

Pages: 352-356

Abstract: This paper states the development of a machine learning model capable of classifying whether a person who has cardiac problems is able to escape from a building if it is affected by an earthquake. The data used to train the model was obtained from a simulation which considered some parameters like earthquake magnitude, BMI, cardiovascular disease, person location within the building, and current evacuation routes. The result of this implementation presents a model able to determine whether a person inside the building could or could not go out of it depending on the parameters previously described, for achieving this goal the use of supervised learning algorithms like KNN and Decision Tree was needed. Also, the case study presents two scenarios, the first scenario presents an evaluation metric at normal walking speed and the second at fast walking speed for a person to escape from an affected building.

Title of the Paper: A Simple BJT Based Circuit for Generating Chaotic Oscillations and Double-Scroll Attractors

 

Authors: Umesh Kumar, Anshuman Chhabra

Pages: 316-319

Abstract: A simple BJT based circuit for generating chaotic waveforms is proposed in this paper. The simple circuit consisting of two BJTs, two diodes, nine resistors, two capacitors and an inductor, is based on Chua’s circuit. The circuit is observed to exhibit the chaotic Double-Scroll attractor pattern as well as non-periodic oscillating current and voltage waveforms during SPICE simulations. The working of the circuit is analyzed and mathematical formalisms are developed to explain the chaotic phenomena so observed. It is seen that the chaotic waveforms are generated as a result of a nonlinear relationship between the current through the inductor and the voltages across the capacitors. These are mathematically modeled as a system of nonlinear differential equations and are presented in the paper along with the observations obtained.


Title of the Paper: Robust Speech Enhancement Based on Singular Value Decomposition and an Efficient Threshold

 

Authors: Ajgou Riadh, Sbaa Salim, Guendir Said, Guettal Lemya

Pages: 307-315

Abstract: In this paper, an approved method is introduced for speech enhancement corrupted by additive white Gaussian noise. Our approach is based on filtering the singular value which is obtained from singular value decomposition (SVD) using HANKEL matrix . The efficiency of the proposed methods is its efficient threshold algorithm that maintains the singular value corresponding to original speech signal and also its intelligibility enhancement by using Savitzky-Golay (SG) filter that reduce musical noise, which is usually present after noise reduction. At first, the algorithm extracts the maximum of singular value (SV) of each HANKEL matrix, so that a SV vector will be obtained representing speech signal energy. We extract the maximum and the minimum of SV vector to estimate the threshold. After filtering the SV, the inverse operation is performed to reconstruct the new Hankel matrices and the enhanced signal. This method will be evaluated in segmental SNR and Perceptual Evaluation of Speech Quality scores measure (PESQ), which led to remarkable results in comparing with traditional methods.

Then the specific own granulation problem is presented, which has concern to the controlled liquid metal jet and film flows for a production of the uniform by size and form particles (granules) cooled with a high rate, to be amorphous or close to the amorphous materials. Such granules of the given size and form are needed for the new material science. The basics of developed theory of the controlled jet and film flow disintegration with further rapid cooling of the drops obtained after flow disintegration are presented together with the new patented granulation devices. The developed methods and devices can be used for production of the amorphous or close to amorphous granules in a wide range of the given sizes, with very narrow (plus-minus 50% deviation of size from the average one).

Pages: 270-276

Abstract: Recently, private hospitals, especially in the UAE, are expected to offer a comfort equivalent to a 5-star-hotel for their patients. Running such a hospital effectively and sustaining it in the competitive market become a struggle. In order to achieve patient satisfaction, private healthcare organisations should improve their service offering by enhancing the quality of their main managerial operations. This could be possible with a knowledge-based framework that represents the good practices of successful organisations’ main managerial operations. The aim of this paper is to present the development of such a framework, and its validation by an expert judgement in a private hospital in the UAE. Data for this research was collected with a semi-structured questionnaire from 13 hospitals across Europe and Saudi Arabia. Results were analysed and evaluated in order to develop the knowledge-based framework. Findings showed that having a knowledge-based framework helps organisations with identifying the gaps in their current operations management and addressing these gaps by applying the proposed framework.


Title of the Paper: Risk Evaluation of Dairy Products Manufacturing Processes Using a Set of Connected Fuzzy Inference Systems

 

Authors: Dayo Stephen Ogunyale, Rene V. Mayorga

Pages: 260-269

Abstract: The objectives of this work are to develop an intelligent system capable of analyzing and evaluating risks in dairy products manufacturing systems. Contaminations from the dairy products and raw milk have contributed to different hazardous Health-related dilemmas around the globe. Having adequate systems in place to prevent these issues is paramount, as dairy products are widely consumed for its nutrition benefit reasons. These benefits can result in catastrophic impacts as a result of failures and unmitigated risk during the industrial processing, thus, the need for proper studying of these failures in dairy production systems is inevitable. Analysing risks associated with dairy products manufacturing help in identifying each failure at every stage of the production. The dairy products manufacturing system risks are classified into four categories namely; Physical, Biological, Chemical, and Environmental risk, which gave a distinctive analysis of the dairy manufacturing processes. Here, a set of five well connected Mamdani Fuzzy Inference System (FIS) models are proposed to solve these dilemmas. The first stage of the study involved gathering data to identify the failure modes using data from operation failures, root-cause analysis log, consumer feedbacks, and the expert’s opinions. These data were used to define the membership functions for the first four FISs, with the expert’s knowledge and opinions. The output of this first four FISs are then fed into the final FIS to evaluate the risk level of the manufacturing system. The RPN criteria used are occurrences, severity, and detectability, which serve as the fuzzy inputs. Each risk for the failures is evaluated for physical, biological, chemical, and environmental risk, with biological risk contributing the highest risk to the consumers due to the microorganisms.

Title of the Paper: The Decision Algorithm Selection for Ensuring the Quality Assurance of the Components of the Multi-Version Execution Environment

 

Authors: Igor Kovalev, Vasiliy Losev, Mikhail Saramud, Mariam Petrosyan

Pages: 243-251

Abstract: The article suggests a selection technique for optimal voting algorithm for the decision block of the multi-version execution environment. It allows you to choose an algorithm that guarantees the quality characteristics of the developed component. Different decision-making algorithms have their own strengths and weaknesses: some are more resistant to related faults, but they do not work adequately with a large percentage of "inaccuracies," while others, on the contrary, are resistant to both "inaccuracies" and relatively unreliable versions, but they are mistaken for each related error, etc. Therefore it is necessary to check all of the algorithms in an environment simulating the characteristics of the system under development. Thus, we get the characteristics of the quality of the algorithm in conditions exactly the same, that it will work in our system. The existent algorithms of a decision making in multi-version execution environments are described in the article. In addition, the own modifications of existing voting algorithms and t / (n-1) algorithm are suggest by authors. The software implementation of the simulation environment that implements simulations of versions with specified characteristics and proposed modified algorithms is considered. Given the characteristics of the system, the environment makes it possible to obtain the quality characteristics of all implemented decision algorithms. If, by results of modeling, there exists an unambiguously superior algorithm, the system specifies it explicitly, if there is no such algorithm, then, the developer is provided with numerical and graphical simulation results for self-selection. The results of the simulation are considered; moreover, the dependence of the reliability indicators of the system on its input parameters is shown. The comparative analysis of various decision algorithms is made basing on simulation results.

Title of the Paper: Generating and Estimating Nonverbal Alphabets for Situated and Multimodal Communications

 

Authors: Serhii Hamotskyi, Sergii Stirenko, Yuri Gordienko, Anis Rojbi

Pages: 232-236

Abstract: In this paper, we discuss the formalized approach for generating and estimating symbols (and alphabets), which can be communicated by the wide range of non-verbal means based on specific user requirements (medium, priorities, type of information that needs to be conveyed). The short characterization of basic terms and parameters of such symbols (and alphabets) with approaches to generate them are given. Then the framework, experimental setup, and some machine learning methods to estimate usefulness and effectiveness of the nonverbal alphabets and systems are presented. The previous results demonstrate that usage of multimodal data sources (like wearable accelerometer, heart monitor, muscle movements sensors, braincomputer interface) along with machine learning approaches can provide the deeper understanding of the usefulness and effectiveness of such alphabets and systems for nonverbal and situated communication. The symbols (and alphabets) generated and esrtimated by such methods may be useful in various applications: from synthetic languages and constructed scripts to multimodal nonverbal and situated interaction between people and artificial intelligence systems through Human-Computer Interfaces, such as mouse gestures, touchpads, body gestures, eyetracking cameras, wearables, and brain-computing interfaces, especially in applications for elderly care and people with disabilities.

Title of the Paper: Direct Torque Control of Induction Motor Using Seven-Level Cascaded Multilevel Inverter with Reduced Number of Switches

 

Authors: P. Rajan, S. Jeevananthan, P. Ranjith

Pages: 173-179

Abstract: With the headway of energy hardware and computerized advancements charge, a few control structures for the AC machines were proposed, keeping in mind the end goal to get execution indistinguishable to those of the DC machine. Among these structures, the direct torque control has been as of late towards the most critical research and most appropriate to mechanical necessities. direct torque control (DTC) is a control strategy in AC drive drives to acquire elite torque control. The traditional DTC drive contains a couple of hysteresis comparators and experiences variable exchanging recurrence and high torque swell. These issues can be unraveled by utilizing space vector relying upon the reference torque and flux. In this paper the space vector adjustment strategy is connected to the another seven-level cascaed multilevel inverter utilizing 5-switches control in the proposed DTC-based enlistment engine drive framework, coming about to a huge decrease of torque swell. Seven-level fell multilevel inverter have been broadly utilized as a part of medium voltage applications. This sort of inverters have a few points of interest over standard two-level VSI, for example, more noteworthy number of levels in the output voltage waveforms, less consonant twisting in voltage and current waveforms and lower exchanging frequencies. This paper underscores the inference of exchanging states utilizing the Space Vector Pulse Width Modulation (SVPWM) procedure. The control plan is actualized utilizing MATLAB/SIMULINK Tool.

Abstract: Tourism was bounced from one ministry to another without being given due importance in the national economy. Fortunately, the current government has reinstated the ministry, taking appropriate measures for the good of the tourism, helping budgetary Romanians to spend their holidays within their country by holiday vouchers. The Romanian ecotourism destinations, no matter of the season, remain Romanians favorites, given the modest prices the owners of these pensions charge. In present, sustainable Romanian destinations are increasingly affected by the new strategic challenges posed by innovative technologies and often related to tourist consumer behavior and environmental pressures. In order to address these challenges, destinations first have to analyze the global trends and then respond proactively (Soteriades et al., 2007), strongly emphasizing that innovation is extremely important, even indispensable to evolution.


Title of the Paper: From D. Bernouilli to M. Allais: A New Paradigm in the Making?

 

Authors: William M. Saade

Pages: 143-153

Abstract: This study revives an approach to elicit human preferences based on the stimuli-response procedure long forgotten. Fifty years ago a new theory, Elementary Catastrophe Theory,(E.C.T.), unfolding a unique Potential in our brain, provided the underlying dynamics needed to fulfill all the desiderata of the so-called school of Psycho-Physics(Weber-Fechner, 1860), seeking to make mathematical sense of the procedure above. The axiomatization of a self-measurement process brings a rationale to the empirical data away from any “a priori” assumption about human purpose. Besides fitting the major landmark criteria in the fields of Value and Utility this 5th degree symmetric polynomial exhibit a characteristic (Negative Schwarz’ Derivative) going a long way to solve controversies and remove roadblocks in the progress of Portfolio Theory. In the Annex we provide an algorithm finding the roots of polynomials of any degree based on the same feature. Finally with this newly-found Human Scale (Cardinal), grounded solely on the axiom of Non-Satiation, Free Energy could dislodge Entropy as a paradigm in this field.

Authors: Md. Shafiqul Islam, Raisa Fabiha, Chinmoy Nath Saha

Pages: 138-142

Abstract: In this paper, we propose a two-dimensional analytical model of single material symmetric Double Gate Stack-Oxide Junctionless Field Effect Transistor (DGSJLFET) for subthreshold region. This model has been investigated and expected to improve subthreshold characteristics and minimize short channel effects. The characteristics of DGS-JLFET are compared with those of the single material symmetric Double Gate Junctionless Field Effect Transistor (DG-JLFET). Our proposed DGS-JLFET exhibits higher Ion/Ioff ratio, less subthreshold swing (SS) and less drain induced barrier lowering (DIBL) when compared to DG-JLFET.

Abstract: Product development challenges have put such an immense pressure to companies like Jaguar Land Rover (JLR) to become more competitive and efficient in the market. The key demand is sustaining the design through product innovation, produce a quality product, shorten the lead time and in a cost effective manner. Lean Product Development (LeanPD) through the Set-Based Concurrent Engineering (SBCE) is an approach that has these capabilities including providing a suitable knowledge environment to support decision making throughout the development process. This paper presents a process of developing a business case framework (SBCE-BC) for the introduction and application of the SBCE principles to justify its effectiveness. The structure of the SBCE-BC framework proposed at the end of this paper presents a generic guideline of having a business case in SBCE by justifying the benefits of its application. The framework was established based on the LeanPD application study at Jaguar Land Rover (JLR).


Title of the Paper: CFD Airfoil Analysis with High Aspect Ratio in Unmanned Aerial Vehicles

 

Authors: Byung Ryoun Kim, Chakun Cheong, Kyoungwoo Park, Byeong Sam Kim

Pages: 120-127

Abstract: Shape optimization of the airfoil with high aspect ratio of long endurance unmanned aerial vehicle (UAV) is performed by the multi-objective optimization technology coupled with computational fluid dynamics (CFD). For predicting the aerodynamic characteristics around the airfoil the high-fidelity Navier-Stokes solver is employed and SMOGA (Simple Multi-Objective Genetic Algorithm), which is developed by authors, is used for solving the multi-objective optimization problem. To obtain the optimal solutions of the design variable (i.e., sectional airfoil profile, wing taper ratio and sweep) for high performance of UAVs, both the lift and lift-to-drag ratio are maximized whereas the pitching moment should be minimized, simultaneously. It is found that the lift force and lift-to-drag ratio are linearly dependent and a unique and dominant solution are existed. However, a trade-off phenomenon is observed between the lift-to-drag ratio and pitching moment. As the result of optimization, sixty-five (65) non-dominated Pareto individuals at the cutting edge of design spaces that are decided by airfoil shapes can be obtained.

Authors: Joon Shik Yoon, Soon-Ik Jeon, Jang-Yeol Kim, Seong-Ho Son

Pages: 107-109

Abstract: We introduce an automatic phase calibration loop circuit and an extended time reversal method for a focused microwave thermotherapy system. We evaluate the loop circuit by measuring the phase errors at the array antenna feeding port. We compare these measurements with those without a loop. The results reveal that the reductions of overall phase are enough to focus fields at a target point.

Title of the Paper: Building Urban Databases for Smart City Applications Using Crowdsensing Techniques by Additional Evaluation of Vision Based Driver Assistance Systems

 

Authors: M. Szántó, L. Vajta

Pages: 96-101

Abstract: Smart city solutions – especially autonomous driving in cities – need detailed model of the environment. The spread of the driver assistance systems, and the growing importance of their vision component, open new possibilities for constructing such database, which describe the environment in deep details online. The onboard vision system of a state of the art vehicle delivers much more information than we need for its basic tasks. By use of additional evaluation of the visual information, and with the installation of extension elements and communication tools we achieve a cheap data source for new applications. By use of a dead reckoning trajectory tracking based motion stereo solution, we can extend the onboard vision system towards a 3D modelling sensor. Although the accuracy of such a solution is strongly limited, the huge amount of the information delivered by the individual agents makes the reduction of noises and the artificial generation of higher resolution possible. Additional illumination (i.e. IR laser strip) makes the calculation of 3D information more effective. The development of the 3D model needs sophisticated picture processing algorithms for separation of the change in the sensed image caused by the movement of the camera from those produced by the perspective transformation. As an example we will introduce our crowdsourcing based solution for the continuous update of road surface quality database. . The windshield mounted video camera of the vehicle extended by a cheap laser light strip illuminator and robust software solution produces detailed description of the road surface profile along the movement’s track. The type of the deviation of the surface from the needed value together with the GPS position of the failure’s location will be transmitted to the central database. Based on this information the maintenance works logistic can be optimized, which reduces the cost of the road repair enormously.

Abstract: Motto:”In Europe today, there are already over 4 million people working for eco-industries. And the green economy sector has been extremely resilient. In fact it has kept growing and creating new jobs through the economic crisis” In Europe today, there are already over 4 million people working for eco-industries. And the green economy sector has been extremely resilient. In fact it has kept growing and creating new jobs through the economic crisis” Karmenu Vella, European Commissioner for Environment, Fisheries and Maritime Affairs. The establishment and the management of a certification system, especially for a multi-national area like the Danube Region can be a challenge. In the benchmarking analysis, the aspects related to simplicity of the systems and their easiness to be transferred have been kept in high consideration. The intensity of the challenge depends also on important initial choices that should be made and that are suitable to simplify/complicate the process. The public/private nature of the system, the possible adoption of existing and ready-to-use standards, the possibility of choosing a second-level certification approach are all aspects to be taken into consideration.


Title of the Paper: An Application of Discrete Event Systems based Fault Diagnosis to German Railway Signaling System

 

Authors: Mustafa S. Durmuş, İlker Üstoğlu

Pages: 70-77

Abstract: Fixed-block railway signaling systems are both regarded as Discrete Event System (DES) due to having DES-like features in their structure and safety-critical due to the fact that the occurrence of a fault may result with a huge loss of life and property. Therefore, DES-based modeling and fault diagnosis methods which are also recommended in the railway related safety standards are applicable to fixed-block signaling systems. On the other hand, the design steps of software for safety-critical systems are guided by software lifecycles. Among different lifecycle models proposed in the literature, the V-model is one of the most well-known software development lifecycle model. In this study, a modification for the V-model is proposed by adding a DES-based fault diagnosis step to the V-model. The proposed method is also explained with a case study on the German Ks signaling system.


Title of the Paper: Compressively Sensed Hybrid PET/MR Imaging with Enhanced Spatial Resolution

 

Authors: Krzysztof Malczewski

Pages: 61-69

Abstract: Considering the success of PET/CT modalities, public expectations for any new combination, such as MR/PET are pretty high. Since MRI does not utilize any ionizing radiation its use is recommended in preference to CT when either modality could yield the same information. Thus, it turns into a perfect anatomical complement to PET. The principal idea behind merging PET and MRI is to combine the functional / metabolic information provided by PET with the high soft-tissue contrast and the functional information offered by MRI. This article presents the new compression sensing based super-resolution algorithm for improving the image resolution in clinical MR-PET hybrid scanners. Despite MR and PET each provide unique and independent information they share the same underlying anatomical features. Hence, rather than treating the data from PET and MR singly, we are able to incorporate both data sets in a simultaneous reconstruction algorithm. A joint sparsity based reconstruction method for multiple sensors, allows these anatomical similarities to improve the two unique and independent data sets. It is shown that the presented approach improves MR-PET spatial resolution in cases when Compressed Sensing (CS) sequences are used. Compressed sensing (CS) aims at signal and images reconstructing from significantly fewer measurements than were traditionally thought necessary. The application of CS in medical modalities has the potential for significant scan time reductions, with visible benefits for patients and health care economics. These methods emphasize on maximizing image sparsity on known sparse transform domain and minimizing fidelity.

Title of the Paper: Obtaining Building Materials from Coal Ash after Separation of the Residual Carbon

 

Authors: Mihai Cruceru, Traian Alexandru Abagiu, Lucica Anghelescu, Bogdan Diaconu

Pages: 45-49

Abstract: There are 108 ash coal landfills In Romania occupying an area of 2823 ha, the volume of stored coal ash representing several thousand million cubic meters. These landfills, even if they were closed, continue to impact negatively the environment by: modifying the composition and quality of the soil in the vicinity due to deposition of ash particles, pollution of ground water by infiltration, accumulation of heavy metals in local flora and damage to human health. Although various measures to diminish the environmental impact are available, the use of coal ash as a potential raw material could be considered as a better solution. The coal ash presents a valuable oxide composition, a suitable fine grain size, which is a major advantage in the production of building materials by excluding the energy required for grinding. This paper presents the main data regarding building materials manufacturing by using coal ash as substitute by up to 50% of raw materials which are obtained usually by destructive action on superficial soil layers.

Authors: Mirela Mazilu, Cipriana Sava, Amalia Niţă, Sabina Gheorgheci

Pages: 32-44

Abstract: Green tourism principles, actually, in Romania, have many effects on every single aspect of the hospitality industry. They don't just relate to the environment however important that may be; they also relate from the way business and marketing is done to interactions with society and culture and to economic stability. Now, the conservation is becoming part of tourist markets, by promoting ecotourism as an element of the so-called green economy, which was proposed as a solution to the on-going crisis at the Rio+20 Summit? Additionally, the complex relationship between tourism and the environment is based on the demand for energy, water, land and materials. The Green tourism and green destinations intensifies the use of natural resources, but how does it contribute to deepening systemic environmental contradictions? .Hospitality, travel and ecotourism comprise a multitude of activities which together form one of the world’s fastest growing and mutually dependent international sectors. In recent years, tourism has become one of Romanian's most important economic sectors and has significant potential to play a further role in Romania's economic renewal. Hospitality, travel and ecotourism research is fundamental to ensuring that the industry has a positive influence on economies, cultures and societies. In the remainder of the paper, a theoretical background is presented and the research hypotheses are developed. The sections describing the methodology, empirical results, and discussion follow. The paper ends with a summary of theoretical contribution, managerial implications, limitations and future research. This paper has four major objectives: to develop a model of destination competitiveness that identifies key success factors in determining destination competitiveness, to develop an appropriate set of indicators of destination competitiveness; to highlight the advantages and limitations of the model; and to identify areas for further research.

Title of the Paper: Correlation Study Between Transit Accident and Routes with Traffic Light Crossings in Rio de Janeiro City

 

Authors: Jaqueline M. R. Vieira, Gisele M. R. Vieira

Pages: 1-5

Abstract: This article depicts the analysis of the correlation between traffic accidents and the traffic light crossing roads in twenty-one districts of the city of Rio de Janeiro, made through georeferenced data and in order to measure the flow of vehicles on the roads these neighborhoods. The Pearson coefficient was used as a way to assess the problem, which applied to data of accidents and crossings has important information about the intensity of this correlation. The main reason of this study is due to the high rate of fatal traffic accidents in Rio de Janeiro and the fact there is no specific data traffic flow in these neighborhoods studied. The methodology can provide insight for better understanding of the problem and it can be applied in other neighborhoods where also there is this kind of information
