Using a function algebra characterization of exponential time due to Monien 5], in the style of Bellantoni-Cook 2], we characterize exponential time functions of linear growth via a safe course-of-values recursion scheme.

In this paper, we first investigate the effect of residual code phase offset on the direct-sequence code-division multiple-access code acquisition scheme using a noncoherent matched filter receiver. We then propose a new code acquisition scheme that is robust to the variation of the residual code phase offset and outperforms the conventional scheme. When the code phase offset normalized to the ...

This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality ...

A Balloon-borne Superconducting Submillimeter-Wave Limb-Emission Sounder (BSMILES) to measure vertical profile of stratospheric minor constituents was developed. BSMILES carries a 300mm-diameter offset parabolic antenna, a 650-GHz heterodyne SIS receiver, and an acousto-optical spectrometer. The SIS junction chip consists of two Nb/A10x/Nb junctions connected by a tuning inductance in parallel....

In a distributed cooperative environment, synchronization is a major issue. Especially when OFDM is employed in the physical layer, frequency offset synchronization is of great significance. In addition, transmitter and receiver IQ imbalances are known to be important implementation issues in OFDM systems. In this paper, the use of a strategy is investigated that enables blind estimation of Car...

This paper presents a 5-300MHz multi-nuclei NMR transceiver designed with spectroscopy for drug discovery in mind. The overall transceiver (transmitter and receiver), is implemented in 130nm CMOS, occupies an active area of 2mm and consumes 12mA from a 1.5V supply. The measured phase noise for the on-chip frequency synthesizer is -110dBc at 10KHz offset when the LO frequency is 212.966MHz (∼H L...

this paper explains offset and develops a strategic approach for the implementation of offset-policy for a buyer country. offset emerges when a country cannot afford to pay cash for non-essential imports, and cannot get cash for many of its products. offset arrangements are most frequently found in the defense-related sector. however, recently, it refers to a range of industrial and commercial ...

A novel time domain multiplexed (TDM) spatial division multiplexing (SDM) receiver which allows for the reception of >1 dual polarization mode with a single coherent receiver, and corresponding 4-port oscilloscope, is experimentally demonstrated. Received by two coherent receivers and respective 4-port oscilloscopes, a 3 mode transmission of 28GBaud QPSK, 8, 16, and 32QAM over 41.7km of few-mod...

This paper describes an advanced sonar ring that employs a low receiver sample rate to achieve processing of 48 receiver channels at near real time repetition rates of 15 Hz. The sonar ring sensing covers 360 degrees around the robot with simultaneously firing of 24 transmitters. The receiver sampling frequency is 250 kHz, compared to previous work at 1 MHz, firstly to maximize the speed of pro...

The purpose of this study was to dynamically examine various offset angles on the N-K table to determine which offset produces a torque pattern corresponding most closely to the isokinetic torque curve of the knee flexor musculature when tested at 60%. Subjects for the study were five college-age male volunteers (age=21.8+/-1.8 yrs, ht=181.9+/-4.3 cm, wt=88.4+/-12.6 kg). Mean peak isokinetic to...
