Design of a 3-D Adaptive Sampling Rate Tracking Algorithm for a Phased Array Radar

손건,홍순목,Son, Keon,Hong, Sun-Mog The Institute of Electronics and Information Engin 1993 전자공학회논문지-B Vol.b30 No.5

The phased array antenna has the ability to perform adaptive sampling by directing the radar beam without inertia in any direction. The adaptive sampling capability of the phased array antenna allows each sampling time interval to be varied for each target, depending on the acceleration of each target at any time. In this paper we design a three dimensional adaptive target tracking algorithm for the phased array radar system with a given set of measurement parameters. The tracking algorithm avoids taking unnecessarily frequent samples, while keeping the angular prediction error within a fraction of antenna beamwidth so that the probability of detection will not be degraded during a track updata illuminations. In our algorithm, the target model and the sampling rate are selected depending on the target range and the target maneuver status which is determined by a maneuver level detector. A detailed simulation is conducted to test the validity of our tracking algorithm for target trajectories under various conditions of maneuver.

隨着中國經濟貿易的發展,中國外資公司勞動關系方面的國際私法問題日益增多,其中最突出的是中國外資公司勞動關系的管轄權和法律适用問題。在處理這些問題中正确認定中國外資公司勞動關系是正确划分中國外資公司勞動爭議管轄權和正确适用法律的前提和基础。爲了公正地保護中外勞動關系中各方当事人,特別是勞動者的切身利益,深入探討中國外資公司勞動關系、中國外資公司勞動爭議的管轄權和法律适用問題具有重要意義。隨着中國市場經濟的發展,中國對外經濟貿易往來取得了長足的發展,勞動者的跨國流動越來越頻繁,中國的外國直接投資公司(以下簡称外資公司)勞動關系方面的國際私法問題日益增多,在這些國際私法問題中最突出的是中國外資公司勞動爭議的管轄權和法律适用問題。正确處理這些問題是關系到公正地保護中外勞動關系中各方当事人,特別是勞動者切身利益的重要問題。在處理這些問題中正确認定中國外資公司勞動關系是正确划分中國外資公司勞動爭議的管轄權和正确适用中國外資公司勞動爭議法律的重要前提和基础。爲了正确處理上述問題,文章擬對中國外資公司勞動關系、中國外資公司勞動爭議的管轄權和中國外資公司勞動爭議的法律适用問題進行深入探討 Along with the development of economy and trade in China, the problems of private international law in the labor relations of foreign direct investment companies within China tend to increase gradually. It is the most salient among those problems to apply jurisdictions and laws to the labor relations of foreign direct investment companies within China. In the process of treating these problems, recognizing correctly the labor relations of foreign direct investment companies within China is the fundamental premise and basis for distinguishing correctly jurisdictions and applying correctly laws in the labor disputes of foreign direct investment companies within China. Therefore, in order to protect fairly the major interests of each party, especially a worker (a labor in the Chinese legal terms), in the labor relations of foreign direct investment companies within China, it is very important and meaningful to study in depth the working relations (labor relations in the Chinese legal terms) of foreign direct investment companies within China and the problems related to applying the jurisdictions and laws to the labor relations of foreign direct investment companies within China.

It is well known that severe symptoms doveloping in the transtentorial pressure cone, secondary to supratentorial space-occupying lesions are caused by descending disturbances in the brain stem function. Among these symptoms the degree of oculomotor dysfunction, dilated pupil or anisocoria, is believed to be the most valid criterion for surgical intervention as determination of prognosis. However, according to many reports, the percentage of pupillary changes in the clinical statistics vary and theories for the pathogenesis are still controversial. Since the reports of Ethelberg and later Vaernet on the impairment of the vestibulo-ocular reflexes in cases of transtentorial herniation, some of neurologists have become interested in this subject. The author has always believed that there was a correlation between the severity of the transtentorial pressure cone and vestibulo-ocular dysfunction. The present study was planned to investigate effects of the 3 neuron response evoked by stimulation to the vestibulo-ocular circuit and to correlate this with other symptoms of the transtentorial pressure cone expecting the response to be as an additional valuable indicator for decompressive surgery and prognosis. Materials and Methods A total of 65 rabbits with normal caloric test, weighing around 2kg. were used. These animals were divided into two groups?, 35 for group I experiment and 30. for,.group II experiment,: Each of these animals served as his own control for the study. Group I experimental study: The balloon of the intracranial pressure producing apparatus which was divised in this study, was placed subdurally through a threphine,in,the, fronto-central region over the vertex. 'Increment of the intracranial pressure was produced by air added' to the balloon of the apparatus: Every 15 minutes cold caloric stimulaions, 2-5°C of water 10-20cc, : were applied, and detailed neurological findings, vital signs, biparietal E.E.G. findings were obtained. Arterial blood pressure was monitored by a femoral artery catheter attached to a Stathahm strain gauge, and respirations were monitored with use of a Bellow type transducer. This data was synchronously recorded on the Grass polygraph and categorized into 4 stages; control base line, dilated pupil caloric positive, dilated pupil caloric negative (change-over stage), and terminal vasoparesis, over a period of 2 hours until the animals showed no cardiac response on E. C. G. The dead animals were subjected to the post mortem examination. Group II experimental study: The total of 30 rabbits was again subdivided in 2 groups of 15 rabbits each. The transtentorial pressure cone was created by the same methods as in the group I experiment. In one group of animals, the intracranial pressure was decompressed at the stage of dilated pupil just before the change-over from caloric positive to negative, and the other group right after the stage. The mortality rate was observed in each group over 48 hours postoperatively. Results and Conclusion 1) The order of developing symptoms in the transtentorial pressure cone is, in general, identical to that of clinical cases. At the stage of change-over from the caloric positive to negative following dilated pupils, the brainstem reflexes; light reflex 86.6% Corneal reflex 86.6% and blink reflex 85.7%, were abolished and followed , by respiratory arrest. Thereafter two thirds of the experimental animals showed a flattened E.E.G. before 0 blooa pressure; and the remaining one third first showed 0 blood pressure and then he flattened E E G before no cardiac response on the E C G 2) As oculomotor dysfunctions, internuclear paralysis was noted in 12.5% of all transtentorial herniated animals which also disappeared at the caloric negative stage. 3) While the mortality rate showed 13.4% in the decompression group at the dilated pupil . with positive caloric response, the another group at the stage immediately following change-over from the positive to negative showed 80%. 4) It is concluded that the vestibulo-ocular response could be used as an additional valuable neurological indicator in the diagnosis of comatosed animals with dilated pupils due to transtentorial pressure cone. However the significance of the response as an indicator might be limited to that period between involvement of the pupilloconstrictor fibers and the paralysis of the somatic nerve fibers to the extraocular muscles.

This study explored to identify the impact of tourist's preference toward the food-related activity experience and of the food-related personality traits on their intention to participate in the activities. A factor analysis and a reliability test was conducted to a total of 300 copies from the internet survey using SPSS 18.0. The proposed research hypotheses were verified through a multiple regression analysis. The results of hypothesis verification are as follows. First, tourist's preference for food-related activity experience have a partially significant impact on intention to participate. Particularly, touring culinary/ wine route is the most highly related to the intention of participation. Second, food neophilia in food-related personality traits has a significantly positive impact on intention to participate, but not significant by food neophobia. The result of this study will be helpful with tourist industry which needs to develop culinary and food-related experience tour program.
