1. MEASUREMENT AND EVALUATION OF ELECTROMAGNETIC POLLUTION IN ONDOKUZ MAYıS UNIVERSITY KURUPELIT CAMPUS IN SAMSUN, TURKEY

Authors: BEGUM KORUNUR ENGIZ , BURAK KURSAT GUL , CETIN KURNAZ

Abstract: In line with technological developments and increasing demand in mobile communications, external electromagnetic radiation (EMR) sources and exposure levels are going up day by day. Therefore measuring and evaluating the exposed EMR levels have become more substantial for human health. It is especially important to determine the EMR levels in campuses where cellular systems used densely. Thus, in this study, EMR levels were measured in Samsun Ondokuz Mayıs University Kurupelit Campus between years 2013-2015 and evaluated. Approximately 400 measurements were performed using PMM 8053 and SRM 3006 at 23 different location in the Campus. The results show that the measured EMR levels (the max. is 2,68 V/m) are far below the limits which are determined by ICNIRP. Additional analyses demonstrate that 55% of total electromagnetic pollution is caused by UMTS2100, 32% is produced by GSM900, 7% by GSM1800 and 6% is aroused from the devices that use the remaining frequency bands

2. THE IMPORTANCE OF INFORMATION SHARING AUTOMATION FOR UNIVERSITY TIMETABLE PLANNING

Authors: ABU BAKAR MD SULTAN , NAJLAA ATEEQ MOHAMMED DRAIB

Abstract: University timetable planning is one of the major management activities for any universities in the world. The quality of the timetabling would ensure the smooth registration process by students and avoided unnecessary adjustment. The quality of university timetable is determined by the degree of soft constraint satisfied while hard constraints cannot be compromised. Timetabling problem is the classic problem for computer science domain. Over the past three decades many research has been carried but mostly focusing on the methods or techniques rather than information sharing. Heuristics approaches such as evolutionary computing was the most appeared in literatures. The complexities and size of the problem depends on many factors such as total number of courses from different departments, and resources such as lectures, rooms and timeslots. The cross departmental academic courses registration increases the complexity that requires good communication to avoid missing courses that suppose

3. DESIGN AND ANALYSIS OF A CFCFC OTA BASED ON THE BEHAVIORAL MODELING OF A 4TH ORDER LOW-PASS HYBRID ΣΔ MODULATOR

Authors: D. CALDERON-PRECIADO , E. CH. BECERRA-ALVAREZ , F. SANDOVAL-IBARRA , J. G. GARCIA-SANCHEZ

Abstract: In this paper SIMSIDES-based behavioral simulation of a 4th order Hybrid ΣΔ (HΣΔ) modulator was carried out to define electrical characteristics of an Analog Building Block (ABB), specifically a fully differential OTA. A set of experiments based on analytical models was defined to analyze the overall performance of the Switched Capacitor (SC) ΣΔ modulator in order to translate the design considerations into a set of values that the design at transistor level can be established by the desired performance of the chosen architecture. In accordance with this design strategy, a fully differential CFCFC OTA was designed according to design rules of a 130nm CMOS process. Simulation results show that an open-loop gain A0 = 60dB, and unity-gain bandwidth f0dB = 1.0GHz are enough to obtain a Signal-to-Noise Ratio (SNR) of 68dB (±1dB) when this OTA is added to the DT ΣΔ modulator. Furthermore the hand-made small-signal analysis of the chosen OTA topology allow us to obtain an analytic design mode

5. MOBILE WRITER VERIFICATION USING A SEQUENCE OF TOUCHING DURATIONS IN WRITING CHARACTERS

Authors: SEIICHIRO HANGAI , TAKAHIRO YOSHIDA

Abstract: In on-line signature verification, a set of dynamic raw data such as xy position and pressure of pen, and/or the processed data such as velocity and acceleration data are used as feature parameters. For biometric authentication on mobile devices, however, another feature which is easily extracted from the behavior of finger touching or tipping on screen should be used. For this purpose, we have studied the individuality included in the on-tablet durations in writing characters. In this paper, we describe the characteristics of on-tablet durations in writing characters and their individuality. According to preliminary experiments using name characters written by 11 persons, we can verify the writer without error only by a sequence of on-tablet durations. By using skilled forgery characters, 1.6% averaged EER (Equal Error Rate) for simulated characters and 3.3% averaged EER for traced characters are given respectively

6. DEPENDENCY THEORY: AN APPROPRIATE TOOL FOR INTERNET/WEB STUDIES

Authors: CHIOMA DEBORAH EKHAEYEMHE

Abstract: The internet, as a unique medium of communication and information, converges different media forms into networks and simultaneously, different modes of communications. This creates difficulty in choosing a theory when carrying out studies on the socio-economic, psychological and political basis of the internet. Selecting a theory that appropriately suit such studies will depend on the theory’s potential to offer a view of a very powerful mass medium that ties its power to the audience members’ dependency on the medium and its contents. This paper, enumerates several reasons why the Dependency Theory of mass communication is most aptly suited for Internet/Web studies. It also explaines the stand of Defleur and Ball-Rokeach who offered this theory and some insights into some studies and opinions of media experts who support the application of this theory on internet studies.

Authors: GIOVANNI MUSCATO , GIUSEPPE MUSSUMECI , MICHELE MANGIAMELI

Abstract: Nowadays more and more applications require a mobile robot able to operate autonomously in an outdoor environment. The accuracy and precision of mapping systems for the working environment is particularly important for the management, control and efficiency of the activity of the mobile robot. For these reasons, mapping systems must be consistent and efficient, and capable to represent in real-time the surroundings, thus allowing the robot, equipped with a system of autonomous movement, the exploration of unknown environments. Here we present a new Web GIS platform able to track the navigation of mobile robots on a georeferenced cartographic data and to assign possible paths or waypoints. The WebGIS platform has been developed using only free and open source software and has been customized with useful tools for the management of the navigation of mobile robots.

Authors: NAVNEET KAUR BAJWA

Abstract: The foremost challenge that FSO come across is the transmitting media linking transmitters and receivers where many weather conditions can influence the capacity of the FSO link such as level of rain, haze, Fog, cloud bursting, scattering and turbulence resulting in fading of the transmitted signal and causing high bit error rate or signal loss at the receiver end. In this work, the impact of turbulence on OFDM-OTSB-FSO system is modeled and analyzed using the gamma-gamma distribution modeling at 10 Gbps over the FSO link. To achieve high speed FSO link under the sway of small and high scale turbulence variations, OFDM-OTSB treated data transmission is reported and demonstrated.

Authors: FLORIN MOLDOVEANU , TITUS IULIAN CIOCOIU

Abstract: Estimating its ego-motion is one of the most important capabilities for an autonomous mobile platform. Without reliable ego-motion estimation no long-term navigation is possible. Besides odometry, inertial sensors, DGPS, laser range finders and so on, vision based algorithms can contribute a lot of information. Stereo odometry is a vision based motion estimation algorithm that estimates the egomotion of a stereo camera through its environment by evaluatingthe captured images. In this paper, we want to give an integrated overview of stereo odometry and the accompanying literature. We want to emphasize the fact that stereo odometry is a chain of several single subprocesses where each relies on its predecessor’s results. A variety of exchangeable methods for each of these subprocesses is available.The key to a more accurate and efficient stereo odometry lies in an integrated analysis of its single subprocesses and the many algorithms available.

12. NEAR FIELD USER DETECTION STRATEGY USING WI-FI/BLE NETWORKS

Authors: HAERYONG JO , MIN CHOI

Abstract: With the spread of IT technologies, we offer a novel near field user detection method by convenient and correct way to take advantage of the Wi-Fi 802.11x technology on smart mobile devices. In this research managers initiate AP mode Wi-Fi service or BLE peripheral advertisement for user detection. The key algorithm in this research is as follows; An advertisement signal is broadcasted only to a person who is closed to the Wi-Fi AP or BLE beacon. If a member has detected advertisement signal, a smart application of the member(or student) will connect and report to the server that the member are near the manager node. If the member does not get the advertisement signal, the smart application of member will report to the server that the users/students are not near the manager node. By this way instructors/managers can conveniently check whether members are near the instructors/manager nodes.

Authors: AMMOR FATIMA-ZAHRA , BOUZIDI DRISS , ELOMRI AMINA

Abstract: Assistance systems require a growing interest from a large community of researchers especially in the context of online learning, their main purpose is to provide a proactive or reactive support to accomplish a learning activity. The diversity of roles and skills required in tutoring (perception of behaviour, interaction analysis, increasing motivation and regulation rhythm, etc.) makes the task of tutor arduous and difficult to manage. Thus, the assistance of tutors is the main focus of several research offering assistance of answers in the form of learning situations models and support tools for the various tasks that the tutor must ensure to his learners. However, elementary and repetitive tasks of tutor are rarely taken into account specifically for their proactive character. Therefore, we propose to support learning scenario of learner by an assistance scenario suitable for his learning style, on the basis of a set of pre-defined assistance objects. The assistance of tutors allows

Authors: FADI WEDYAN , HANI BANI-SALAMEH , SUZAN WEDYAN

Abstract: Smartphones and tablets are gaining more popularity due to their increasing capabilities and affordable prices. While most of the applications built for these devices are business, social, or entertainment oriented, few applications provide tools for developers. This is because of the limited screen size and the virtual keyboards that do not provide a comfortable programming environment. In this paper, we propose a framework, called CodeRoid, for developing Java programs that can be used on tablets and smartphones. Using CodeRoid, developers visually interact with the device to specify the specifications of the required code and CodeRoid automatically generates the required Java source files. CodeDroid provides the building programming blocks which the developer can choose and customize. CodeRoid checks the syntax of the produced Java files. In order to minimize the memory and computational requirements. Java source files can be sent to a server to produce the bytecode. Therefore, a co

Authors: CENGIZ POLAT UZUNOGLU , KORAY GURKAN , MUKDEN UGUR , SERAP CEKLI

Abstract: Power transformer transients, which are originated from non-linear operating characteristics, may cause failure of a power system. In this study, a special resonance phenomenon where overvoltages observed due to switching capacitances of the line is investigated. This situation is detected while high voltage side of the transformer is open circuit (no-load) and the low voltage side is connected to a transmission line through nonlinear switch (or breaker). This special resonance is caused by the interaction of leakage inductance of the transformer windings and the switching capacitance. A test setup containing 220V/34.5kV transformer is employed for realization of simulation results obtained by SPICE analysis. In order to simulate switching capacitance, a capacitance of 5.54μF is connected to low voltage side. The recorded and simulated test results show good correspondence. Observed overvoltages are analysed by continuous wavelet transform (CWT) and fast Fourier transform (FFT) techniq

Authors: EMILIO G. PIRACCI , GASPARE GALATI

Abstract: This paper presents a method for the scheduling of a multifunction radar based on an active phased array of the conformal type (frustum of cone). This type of antenna obtains a 360 degrees horizontal coverage by a number M of sectors each one belonging to a sub-array, where different non overlapping sub-arrays can illuminate different targets at the same time. This operation has both the advantages of a rotating antenna and those of the electronic scan of a fixed-faces multifunction radar. In this context, a scheduling algorithm has to organize a number of parallel radar tasks respecting the constrains on the update intervals. The goal is to implement a scheduling algorithm for a system quite similar to a fixed-faces multifunction phased array radar, with the significant difference that the faces number and pointing directions are variable and adaptive to the scenario. An optimization model is presented and then a heuristic models is discussed with some computational results.

Authors: CAMILLA BIANCHI , CARLO SCHOENHOLZER , CLAUDIO MINORETTI , GIULIA CAPPOLI , GIUSEPPE PONTORIERO , GIUSEPPE ROMBOLA , GIUSTINA CASAGRANDE , MARIA LAURA COSTANTINO

Abstract: Intra-Dialysis Hypotension (IDH) is one of the main hemodialysis related complications, occurring in 25-30% of the sessions. The factors involved in the onset of hypotension in patients undergoing dialysis are due both to clinical conditions (e.g. presence of vascular or cardiac diseases, neuropathology, anemia) and treatment settings such as temperature of the dialysate, sodium concentration, buffer composition, ultrafiltration rate, etc. The patient’s peculiar reaction to the treatment implies difficulties in preventing IDH episodes. This work explores the possibility to use a multivariate analysis of clinical data to quantify the risk to develop IDH at the beginning of each session. The study is framed in the DialysIS project (Dialysis therapy between Italy and Switzerland) funded by INTERREG – Italy – Switzerland and Co-funded by European Union. Data referring to a total of 516 sessions performed on 70 adult patients undergoing dialysis treatment (50 patients enrolled at A. Manzoni

Authors: SANGHUN YUN , WON-SEOK KANG

Abstract: Medical imaging is playing the key role in diagnosing and treatment of diseases. For making accurate decisions, the images acquired by various medical imaging modalities must be free from noise. So image de-noising became an important pre-processing step in Medical image analysis. In this paper, we propose a new de-noising method for medical images. Our method divides up the medical image into multiwindows and assigns the optimal mother wavelet function to each windows. And we are using an n-gram based wavelet learning technique in order to investigate optimal wavelet sequences for an image de-noising. The wavelet learning approach uses Mean Square Error (MSE) as a feature to generate an n-gram table. The performance of the proposed method is compared with the existing methods using Peak Signal to Noise Ratio (PSNR). The results showed that the proposed method has a better PSNR than the previous methods

Authors: F. BERRAHIL, K. TALBI , KHERIEF NACEREDDINE MOHAMED

Abstract: Rayleigh–Bénard convection is a fundamental phenomenon found in many atmospheric and industrial applications. Many numerical methods have been applied to analyze this problem. The effects of oscillatory flow structures on transient convective heat transfer in an air-filled shallow enclosure with a vibrating side wall are investigated. Oscillatory flows and Rayleigh- Bénard convection have been extensively studied. In the present study, fluid motion is driven by the periodic vibration of the enclosure side wall. The vertical walls of enclosure are adiabatic while the bottom wall is isothermally heated and the top wall is kept at an initial temperature. The fully compressible forms of the Navier-Stokes and energy equations are considered to compute the interaction of oscillatory and gravitational flow fields. A finite-volume method based, explicit time-marching Flux-Corrected Transport Algorithm is used to simulate the transport phenomena in the enclosure. The results of a test case simu

27. ENHANCED POSITIONING TECHNIQUE WITH QR CALIBRATION

Authors: A.S. JA’AFAR

Abstract: This paper describes an integrated positioning system that can be used for both indoor and outdoor navigation. The GPS (or any other system) in many scenarios is not sufficiently accurate especially for indoor. Even at a fixed location the accuracy is slightly changing with time due to signal propagation environment condition where current parameters do not reflect this. To address this, we propose a new criteria call “accumulated accuracy”. With this new parameter the GPS accuracy is estimated in a practical way using real data. In this paper, a sliding window technique is proposed for improving “accumulated accuracy” and it show improvement. In addition to this, the QR calibration is introduced for further improving the “accumulated accuracy”. This technique can also be applicable to various other positioning techniques.

Authors: AKRAM KOUT , SAID LABED , SALIM CHIKHI

Abstract: Mobile Ad hoc network (MANET) is an autonomous system of mobile hosts (nodes) connected by wireless link forming a temporary network without the aid of any established infrastructure or centralized administration. Typical applications of MANETs are: emergency and rescue operations, disaster relief efforts, military operations and exploration mission where cellular infrastructure is unavailable. The main problem of mobile ad hoc networks is to design routing protocols allowing for communication between the hosts. The dynamic nature of ad hoc networks makes this problem especially challenging. Communication in MANET is multi-hop due to limited transmission range; this decentralized operation relies on the cooperative participations of all nodes. MANETs are considered as complex system characterized by high dynamic topology, local interactions, auto-organization and emergence. Modeling and simulation are very important in the design and development of distributed interacting system becaus

Authors: LIAN GUODONG , WAN XIN, WANG DUO , WANG XIAOHONG , YU HONGLIANG

Abstract: Conventional proportioning control of cement raw mill is basing on off-line analysis results obtained once per hour. According to the given values of the indexes K, n and p (sometime Fe2O3 used instead of p), operators adjust proportions of raw materials with operating experiences. Due to the time lag in Analysis result and inaccuracy, the indexes of raw material fluctuates between control action intervals and the raw mill quality is low. To solve this problem, we present an intelligent control scheme for cement raw mill quality control based on online compositions analysis results. In this control system, the chemical composition in raw mill is measured in real-time and comprehensively analyzed. A condition-based intelligent control method is then used to optimally control the process. The application in one Cement Enterprise proves quality and efficiency of the system.

33. USE OF OUTLIER DETECTION IN DATABASE AVAILABILITY ANALYSIS

Authors: MARIO ZGELA

Abstract: Usually, database is available and accessible by authorized users. However, there are abnormal situations resulting in database unavailability. Since irregularity may be related to the notion of outliers, in this paper it is checked if outlier detection may be helpful in finding out abnormality in database usage and so improving the process of database availability analysis.

Keywords: s-outlier detection, database availability, quartile range, database login

34. A SERVICES FRAMEWORK FOR USING SOCIAL WEB AS SOCIAL SENSOR WEB

Authors: D. KOTZINOS , G. KARIOTIS , L. THEODORIDOU , N. PETALIDIS , S. KLEISARXAKI , V. CHRISTOPHIDES

Abstract: Online social networking sites carry a lot of information organized around the people who actually submit it. They rely a lot on the interconnections between the actors of the network and they relate the generated information in terms of connections or ties among those actors. On the other hand, social networks carry a lot of information in real time or almost real time since people “report” information as they see it unfolding before their eyes. We are targeting this information and we try to understand when this information can be related to refer to a single event, which has both a spatial and a temporal dimension. These social sensors can alert us on what is happening in the society when it happens and by aggregating the different reports from people who are on the scene. In order to achieve that we suggest and describe a set of services that can be used for collection of the information, identifying the discussion topics and provide at the end an alert if the discussion qualifies
