No full text4th Electric Electronics, Computer Science, Biomedical Engineerings' Meeting, EBBT 2018 -- 18 April 2018 through 19 April 2018 --Çeliker, Denizhan (Arel Author), Erçelik, Can (Arel Author), Duru, Dilek Göksel (Arel Author)Heart rate monitoring using wrist-type photoplethysmographic (PPG) signals during driving is of vital importance, since a sudden infarct or an asynchronous heart rhythm might cause life threaten consequences. In this work, design and validation of an in-house developed wrist-type photoplethysmographic heart rate ambulatory monitoring device is proposed. Signal decomposition and spectral peak extraction as a feature of abnormal heart rhythm is implemented with the proposed wrist-type device with verification. Estimation accuracy is examined. To reach increased heart rate for tracking spectral peaks, subjects are asked to run at a peak speed of 12 km/hour. Thereafter monitoring is done and results from 5 subjects is recorded. The recorded data by designed wrist-type monitor and routine (classical) monitoring showed that the average absolute error of heart rate estimation was 2.5%. Future work of this pilot study will focus in implementation of the monitoring device with a smart notification system i.e. to nearest hospital. This framework is of great values to wearable devices where the design is not limited to drivers' safety, also to ambulatory monitoring of elderly people. © 2018 IEEE
Fully Automated Segmentation of Renal, Cortex and Medulla
No full text#nofulltext# --- Tulum, Gökalp (Arel Author), Artuğ, N. Tuğrul (Arel Author), Osman, Onur(Arel Author)It is assume that volumes of cortex and medulla are related with recovery of the kidney after transplantation. In this work, a fully automated segmentation and volume calculation method is proposed for determining renal volumes. 10 kidneys of 5 donors are used as a dataset. When the output volumes of the proposed system were compared to the golden standarts, Volume error rates are obtained as %03,97 +/- 0,02for total renal volume, %8,71 +/- 0,06 for cortex volume and %20,13 +/- 0,2 for medulla volume
Search for hc ??+?-J /? via ? (3686) ??0?+?-J /?
No full textUsing a data sample of 448.1×106 ?(3686) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition hc??+?-J/? via ?(3686)??0hc. No signals of the transition are observed, and the upper limit on the product branching fraction B(?(3686)??0hc)B(hc??+?-J/?) at the 90% confidence level (C.L.) is determined to be 2.0×10-6. This is the most stringent upper limit to date. © 2018 authors
Design Spatial and Non-Spatial Data Modelling Based on the Ladm Structure for Landregistry and Cadastral System in Turkey
No full textPolat, Zeynel Abidin (Arel Author)In land administration, spatial data manegement plays the important role of defining physical characteristics of land parcels in an accurate and discernible manner. A complementary part of spatial data infrastructure (SDI) is an effective information infrastructure that serves as the backbone of the land administration system. The paper provides a framework that supports adoption of spatial data modelling based on Land Administration Domain Model (LADM) for Turkish Land Administration System (TLAS). For this purpose, a spatial and non-spatial data model based on LADM is designed concerning the single space units subject to condominium in Turkey. The proposed data model is more comprehensive, capable of organising a wider range of spatial data, and should facilitate wider exchange of land information. The model is unique because it can support a very wide range of spatial units. Furthermore, the model was developed to help establish a national spatial data infrastructure LADM-based. To conclude, the developed model is a standardised model that could be used for local and international exchange of spatial and non-spatial data concerning land administration matters
Redefining Privacy in Reflexive Modernity: An Intergenerational Research
No full textKodak, Dilge (Arel Author)This study focuses on the historical changes in the concept of privacy-both at the level of the individual and at the level of society. These changes have been evaluated in relation to the question of modernity. With the advent of information socie-ty, modernity developed a dimension of thoughtfulness. In other words, evolution has changed many layers of society. This change has affected the public and the private space, especially at the level of the individual. The borders between the public and the private have been transformed. Along with reflexive modernity, the use of new communication technologies has shifted the boundaries between individuals and geographies. As a result, and sharing and communication have gained a global dimension. In this process, the emergence of surveillance and the spread of social-sharing platforms has reshaped and transformed the phenomenon of privacy. In today's information society, privacy is conceived differently by different peo-ple. People's conceptions are also influenced by inherited meanings. In addition, the following aspects related to privacy are also conceived differently: social changes, media use, global indicators, religion, surveillance, and risk society. The research adopts a phenomenological approach. It involved interviews with women and men from three distinct generations. The interviews showed that some of the aspects related to privacy have been conceived similarly across generations, whereas some aspects have been conceived differently. As a result, the question of confidentiality cannot be defined in a clear and definite manner
Impact of EV Parking Lot on Distribution System Reliability
No full textGüner, Sıtkı (Arel Author)Due to the aggregating feature of the parking lot, it can be served as a distributed energy resource (DER) for distribution grid. This study presents the impact of electric vehicle parking lot (EV PL) on distribution system reliability level for an intended operation period. Stochastic storage capacity model of a sample EV PL that was recently proposed is used for the assessment of the aforementioned impacts on the reliability level of a distribution feeder located at the Thrace part of Istanbul distribution system. Reliability improvement of distribution system through EV PL is evaluated using SAIFI, SAIDI, and ENS indices. Moreover, impacts of EV PL on load point reliability indices are also evaluated and discussed
Calculation of the C-P-C-V as a function of temperature close to the melting point in benzene
No full textTarı İlgin, Özlem (Arel Author)The temperature dependence of the C-P - C-V is calculated at constant pressures using the observed volume data from the literature for solid and liquid benzene near the melting point. Our calculated values are compared with some earlier treatments and we find that they disagree at constant pressures for the solid benzene, whereas for the liquid benzene agreement is reasonable in terms of the order of magnitude between our calculated C-P - C-V and those predicted from the Peng-Robinson equation of state. Our calculated C-P also agrees with the experimental data at normal pressure and has lower values at higher pressures in liquid benzene. Our treatment given here indicates that the C-P - C-V and the heat capacity C-P can be calculated from the molar volume as a function of temperature at constant pressures using the thermodynamic relations for the solid and liquid benzene near the melting point
An Assessment of the European Union's Impact On Resolution of the Kosovo Impasse
No full textKelkitli, Fatma Aslı (Arel Author)The Kosovo War of 1998-1999 while being the final nail in the coffin of Yugoslavia became the harbinger of an active and involved European Union (EU) foreign policy in the Western Balkans. The Union started the biggest and most expensive mission beyond its own borders in Kosovo which acquired a much more expansive character in December 2008 following the United Nations' transfer of responsibilities in the areas of police, customs and the judiciary. This article examines the political, legal/security and financial instruments used by the EU to not only strengthen the state capacity in Kosovo but also to end the disagreement between Serbia and Kosovo which still has the potential to explode and sweep the Western Balkans into another cycle of conflict, instability and migration

No full textEroğlu, Kübra (Arel Author)26th IEEE Signal Processing and Communications Applications Conference, SIU 2018 -- 2 May 2018 through 5 May 2018 --Order to save energy and to use energy resources efficiently, automatic occupancy determination based on sensor information is performed and energy is adjusted according to the demand in a closed area. In this study is used records consisting of T (temperature), H (humidity), L (light level), CO2 (carbon dioxide) and R (humidity ratio) sensor data. Occupancy analysis based on sensor data has been performed with REPTree (Reduced Error Pruning tree), NB (Naive Bayes), SVM (Support Vector Machine) and KNN (K Nearest Neighbor) classification algorithms. The highest classification success (97.98%) was obtained with the REPTree classification algorithm. Then the importance of the attributes is determined by the CFS (Correlation-based Feature Selection) algorithm to be taken into account in reducing costs in the data collection step and the effect of the attributes on the classification performance is examined. Finally, ensemble algorithms Adaboost, Bagging, RandomSubSpace are used to increase classification success and achieve more stable results. The performance evaluation criteria are shown that the ensemble algorithms improve the classification success. The highest classification success (98.28%) was obtained by using the Adaboost community algorithm together with the ADTree classifier. According to the sensor values in the dataset, the use of office room was determined with high success rate. © 2018 IEEE
