        “What the hell is he?” Double Agency in Ulysses

        ( Omer Kazmi ) 한국제임스조이스학회 2017 제임스조이스저널 Vol.23 No.2

        This paper examines the “Cyclops” episode of Ulysses and how nationalism and Jewishness create a sense of double agency in the episode. Not only Bloom, but also the other characters in Barney Kiernan's, are double agents: their identities blur and commingle with Bloom's presence. The tension between the Irish nationalists in the pub and Bloom's perceived Jewishness highlight that double agency; yet, there is also a tension in the narration itself with the interruptions in the narrative. The narrator too produces paranoia because he is an unknown character who is paranoid himself. The entire episode works to show that paranoia surrounds identity, and any clear definition of national identity―especially for nationalists whose supreme goal is freedom from colonial rule―is troubled. But double agency, the episode suggests, is how identity works.

        Effect of Self-photoperiod on Live Weight, Carcass and Growth Traits in Quails (Coturnix Coturnix Japonica)

        Omer,Coban,Ekrem,Lacin,Nilufer,Sabuncuoglu,Zekeriya,Ozudogru 아세아·태평양축산학회 2009 Animal Bioscience Vol.22 No.3

        The weekly liveweight gain, growing and stress parameters of quails bred using two different types of lighting for 6 weeks following hatching were examined in this study. The first type of lighting was 23 L:1 D, continuous lighting (CL), widely used in the commercial system and the second was a self-photoperiod (SP) system consisting of a continuously lit chamber and a dark chamber the quails could move to as they wished. On the first 15 days, no difference was found in liveweight gain between the two breeding systems. On the 6th week when the trial was completed, the liveweight of the male quails upon which CL lighting was used was 159.03 g while the weight of males in the SP group was 174.43 g; these values in female quails of the CL group were 179.15 g and in the SP group were 200.68 g. The CL group had lower testis volume (TVOM, cm3) and testis weight (TW, g) than the SP group, however there was no difference between the groups in testis weight/body weight rate (BWTW %). In female quails, the ovary weight (OW, g) and the ovary weight/body weight rate (BWOW, %) values were higher in the SP group. The CL light regime was concluded to cause stress in male quails (CL, Heterophil/Lymphocyte ratio (H/L): 0.27; SP, H/L: 0.17). In conclusion; the SP system allowing the quails to regulate their light periods increased liveweight gain and enabled sexual maturity to be gained at an earlier period than in quail on the CL system and improved their welfare.

        Can a Periodic VER Raise Importing Country Welfare?

        ( Omer Gokcekus ), ( Edward Tower ) 세종대학교 경제통합연구소 1997 Journal of Economic Integration Vol.12 No.4

        Several authors have argued that if exporting firms anticipate a voluntary export restriction in a future period, and they expect VERs to be allocated in proportion to past exports, then they have an incentive to dump in the earlier period. In this paper we ask: How does a regime characterized by periodic VERs affect aggregate welfare, consumer welfare and import-competing producer welfare in the importing country? We discover paradoxically, that the answers are all uncertain. However, such a regime always shrinks worldwide efficiency, and normally, for the importer it shrinks aggregate welfare and consumer welfare and raises producer welfare. (JEL Classification: F13)

        영상기반 관절 각도 특징 분석을 이용한 사람 식별

        Omer,Faruk,Ince,Ibrahim,Furkan,Ince,Mustafa,Eren,Yildirim,박장식,송종관 제어·로봇·시스템학회 2018 제어·로봇·시스템학회 논문지 Vol.24 No.3

        In this study, the angles between gait-relevant joints are considered a robust and differential feature set. The aim of this paper is to develop an approach that identifies a person's gait cycle using body-joint information. The proposed approach acquires six different joint angle measurements using an RGB depth sensor, and then stores these in a queue-attribute collection. A genetic algorithm is then applied to reduce the number of features from 120 to 43. Following this, the data is trained with both a random forest classifier (RFC) and a K-nearest neighbor (KNN) algorithm . An average accuracy of 95.64% and 91.98% for gait analysis and identification with RFC and KNN algorithms respectively.

      • MODIFICATIONS IN THE FUEL OIL SYSTEM OF KHARTOUM NORTH POWER STATION TO SUIT THE WAXY SUDANESE FUEL OIL

        Omer,Mohammed,Abdelaziz,Eui,Gyun,Na,Soek,Hyong,Oh 대한기계학회 2006 대한기계학회 춘추학술대회 Vol.2006 No.6

        The work presented in this research consists of some modifications and suggestions to solve some of the operational problems that appear in Khartoum North Power Station (KNPS) after using the waxy Sudanese fuel oil instead of the imported fuel oil. The fuel oil system in Khartoum North Power Station (KNPS) was designed for heavy fuel oil of bunker (C) type according to the British standard. The Sudanese fuel oil is a paraffin-based oil, therefore it contains relatively large amount of paraffin wax content (10-20%). This relatively high wax content raises the Sudanese fuel oil pour point and ?consequently generates problems in the fuel oil unloading process, storage process, delivery process, and fuel oil combustion process in the burners. So this research is deals with the problems associated with the fuel oil system, which can be divided into three parts, the first part deals with the unloading areasystems, the second part of this research deals with the fuel oil storage tanks systems, and the third of this part deals with the delivery systems, Some of the new modifications are suggested, to command fully the drawbacks and negative side effects resulted from the usage of the waxy Sudanese fuel oil in Khartoum North Power Station (KNPS) instead of the imported fuel oil bunker (C).

        Ratio estimators based on a ranked set sample in a finite population setting

        Omer,Ozturk 한국통계학회 2018 Journal of the Korean Statistical Society Vol.47 No.2

        This paper considers the ratio estimator in a finite population setting in a ranked set sampling (RSS) design, where the sample is constructed either with or without replacement policies. It is shown that the proposed ratio estimator is slightly biased, but the amount of bias is smaller than the amount of bias of a simple random sample (SRS) ratio estimator. For the proposed ratio estimator, the paper provides explicit expressions for its mean square error and precision relative to the other competing estimators. It is shown that the new estimator has a substantial amount of improvement in efficiency with respect to SRS estimator. The proposed estimator is applied to two different finite population settings to estimate population mean.

      • TRANSPORTATION AND HANDLING PROBLEMS IN USING THE WAXY SUDANESE FUEL OIL IN KHARTOUM NORTH POWER STATION

        Omer,Mohammed,Abdelaziz,Eui,Gyun,Na,Soek,Hyong,Oh 대한기계학회 2006 대한기계학회 춘추학술대회 Vol.2006 No.9

        The work presented in this research consists of some solutions and suggestions to solve some of the transportation and handling problems that appear in Khartoum North Power Station (KNPS) after using the waxy Sudanese fuel oil instead of the imported fuel oil. The fuel oil system in Khartoum North Power Station (KNPS) was designed for heavy fuel oil of bunker (C) type according to the British standard. The Sudanese fuel oil is paraffin-based oil, therefore it contains relatively large amount of paraffin wax content (10 - 20%). This relatively high wax content raises the Sudanese fuel oil pour point and consequently generates problems in the fuel oil transportation process, and handling process. The characteristics features of the Sudanese fuel oil are high waxy content, non- distinctive partial refined oil products, variation in type, and relatively considerable sediments content. The transportation and handling means should be changed to overcome these problems, and to maintain the same original performance. So this research is deals with the problems associated with the transportation system, and the handling system. Handling system was divided in to two parts, the first part deals with the unloading systems, the second part deals with the delivery systems, Some of the these new modifications are suggested, to command fully the drawbacks and negative side effects resulted from the usage of the waxy Sudanese fuel oil in Khartoum North Power Station (KNPS) instead of the imported fuel oil bunker (C).

        Synthesis and characterization of paramagnetic Mn doped Ca2P2O7 ceramics by sol-gel method

        Omer,Kaygili 한양대학교 세라믹연구소 2015 Journal of Ceramic Processing Research Vol.16 No.1

        Pure calcium pyrophosphate (Ca2P2O7) and Mn doped Ca2P2O7 based ceramics were synthesized by sol–gel method, and were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy. The average crystallite size and crystallinity are affected by the addition of lower amount Mn, whereas, the content of Mn having higher amounts did not cause a remarkable effect on these parameters. The bands belonging to the pyrophosphates were detected. The ceramics exhibit the paramagnetic behavior at room temperature and the magnetic susceptibility increases from 7.28 × 10–7 to 2.48 × 10–5 emu g–1 Oe–1 with the addition of Mn. The microstructure of the ceramics is affected by the content of Mn. All the samples are composed of the fine-grained particles, and no impurity is observed.
