We describe a new approach to real-time implementation of track record and trajectory control of robotic manipulator with eight joints based on monitoring simulator. Trajectory generator uses the kinematic equations of the arm to convert the task description into a series of set points for each of the joint control loops, while the joint controllers, with simple algorithms for just one joint can move at a fast sampling rate, guaranteeing a smooth motion. The proposed control scheme is robust, fast in computation, and suitable for real-time control. Moreover, this scheme does not require any accurate parameter information, nor values of manipulator parameters and payload. Reliability of the proposed technology is veriefied by monitoring simulation and experimental of robot manipulator for the smart factory with eight degrees of freedom.

Recently a great deal of people are taking legal action against the housing provider due to the defects of their Apartment house. And most of the housing companies are spending a huge amount of expenses and efforts to keep their brand value. This essay will carry out time series analysis the 20 housing district which are constructed by huge construction companies. This analysis itemised by metropolitan area(Seoul) and others to keep the degree of reliability, and converted future defect maintenance cost into current cost applied by discount rate to figure out suitability of defect maintenance cost. Even though, this essay is not able to represent standard of defect maintenance cost due to the insufficiency of record, while it will be assisted as a referance when long-term record of time series is estabilished.

The purpose of this research which was conducted by surveying the transfer consultation records from 360 medical institutions such as general hospitals, hospitals, clinics to the Emergency Medical Center at E University Hospital for six months(Jan. 1, 2000 - Jun. 30, 2000) are to standardize & complete transfer consultation record of hospitals at the 1st & 2nd referral level and to give patients transferred emergency medical center medical information services on a better quality. The conclusions and suggestions from this study were summarized as follows; (1) Examing the distribution of the referral medical consultation(transfer) sheet type, surgery part local clinic sheet types were 34.4%, medical part local clinic sheet types were 26.7%, undifferentiated local clinic sheet types were 23.9% and hospital level sheet types were 15.0%. (2) The items of the transfer consultation records had been standardized more than 75% in the order of patient's name, date, doctor's name, diagnosis, patient's status, impressions. (3) That the degree of recording completion on these items is in the order of patient's name, date, diagnosis, impressions was revealed. (4) Because the standardization and the degree of recording completion are very low in the patient's gender, age, address, electronic recording system was needed for more perfect input of initial patient informations. (5) This standardizing & complete recording on examination and medication will prevent re-examination and abuse of medication for patients transferred emergency medical center. (6) EMT Transfer System should be fixed in all medical institute for the standardizing & complete recording on care period and departure time will give many emergency patients the proper treatments at the proper time. (7) It was revealed that developing new standardized transfer consultation record & using electronic recording system are needed. (8) The complete recording & Fast Track System were needed for higher rate of bed operation at emergency medical center and more hospital profit.

The spectrum of impulse response signal from an impulse hammer testing is widely used to obtain frequency response function(FRF) of the structure. However the FRFs obtained from impact hammer testing have not only leakage errors but also finite record length errors when the record length for the signal processing is not sufficiently long. The errors cannot be removed with the conventional signal analyzer which treats the signals as if they are always steady and periodic. Since the response signals generated by the impact hammer are transient and have damping, they are undoubtedly non-periodic. It is inevitable that the signals be acquired for limited recording time, which causes the finite record length error and the leakage error. In this paper, the errors in the frequency response function of multi degree of freedom system are formulated theoretically. And the method to remove these errors is also suggested. This method is based on the optimization technique. A numerical example of 3-dof model shows the validity of the proposed method.

In this paper, we present a record-replay technique based on interrupt logging and reproduction. Race conditions have been considered as the main source of nondeterminism in conventional record-replay approaches. However, interrupts are another source of nondeterministic computer system behavior, which must be reproduced at accurate time points, let alone the order of interrupt occurrence. We show that an interrupt-based replayer can be efficiently and effectively implemented by using hardware performance counters and debugging functionality. Experiments also show that the runtime overhead of the interrupt-based replayer is sufficiently low.
