Vehicle Detection by Sensor Network Nodes (2004)

This report presents the algorithm development and experimental work of the sensor node signal processing for vehicle detection. The signals used for vehicle detection are acoustic and magnetic signals. The acoustic signals are characterized by short time FFT analysis and two acoustic vehicle detection algorithms are proposed: the Adaptive Threshold algorithm (ATA) and the Min-max algorithm (MMA). The ATA detects vehicle by searching for a sequence of 1's after slicing the acoustic energy curve using an adaptive threshold. The MMA detects vehicles by searching the local maximum in the acoustic energy curve. Real time tests and offline simulations demonstrate the effectiveness of the two algorithms. For magnetic signals, a simple threshold slicing algorithm is utilized and real time tests give good performance. Finally, FPGA implementation of ATA is also presented for power efficiency requirement and the implementation justifies the use of dedicated hardware for low power implementation.
Blockchain-Based Authentication in IoT Networks (2018)

IoT networks are designed to connect as many devices as possible. Since any device can be connected to an IoT network, it faces an authentication issue, which may be exploited by attackers to break into the IoT network. A solution discussed in this paper is to make use of blockchain technology to authenticate IoT devices before it joins an IoT network. Based on the characteristics of blockchain, it can be used to create the digital identification of IoT devices and authenticate them. Authenticated Devices Configuration Protocol (ADCP) is proposed to achieve this authentication process. All results of the solution have been demonstrated by a fully working implementation, and do not solely rely on theoretical considerations or simulations.
Displacement Monitoring of Stacked Piezoelectric Actuator by Observing Induced Charge (2008)

This paper deals with condition monitoring of a piezoelectric actuator using induced charge for precision positioning. When conductive plates are attached on each end of the piezoelectric actuator to which voltage is applied, charges induced in plates are proportional to internal charge, which indicates piezoelectric actuator displacement. The induced charge indicates piezoelectric actuator deformation. Because the relationship between deformation and induced charge has low hysteresis, displacement is measured by observing the induced charge, possible at high driving frequency because the piezoelectric actuator is driven with a voltage source with a low output impedance. The induced charge corresponds to the internal charge and displacement in experiments. A static load to the piezoelectric actuator is also detected.

Novel Insights from Genetic and Molecular Characterization of the Human Clock (2007)

Biological rhythms govern the ebb and flow of life on planet Earth. Animals have an internal timekeeping mechanism that precisely regulates 24-hour rhythms of body function and behavior and synchronizes them to the day/night cycle. Circadian pacemakers trigger behavioral and physiological processes that dictate our daily rhythms. Despite the importance of the circadian clock to all aspects of our physiology and behavior, the opportunity to probe the human circadian clock only recently became possible with the recognition of Mendelian circadian variants in people (familial advanced sleep phase syndrome, FASPS). We have now cloned several genes and identified mutations causing FASPS. Study of these genes and the proteins they encode and engineering of the human mutations into mouse models are allowing study of this fascinating phenotype and yielding novel insights into circadian regulation in humans. Ultimately, such work will allow us to understand the similarities and differences between the human clock and those of model organisms. In addition, recent studies have also linked disruption of the circadian clock with numerous ailments, including cancer, cardiovascular diseases, asthma, and learning disorders. Thus, studying the molecular mechanism of human circadian rhythmicity will have an enormous impact on our understanding of human health and disease. It should also lead to new strategies for pharmacological manipulation of the human clock to improve the treatment of jet lag, various clock-related sleep and psychiatric disorders, and other human diseases.
Tuberculosis of the duodenum. (1979)

At present, tuberculosis of the intestinal tract is rare in the United States. When gastrointestinal disease is seen, 85--90% of cases involve the ileocecal area. A case of tuberculosis of the duodenum unassociated with pulmonary disease is described. Although fiberoptic enndoscopy, abdominal ultrasonography and computerized axial tomography were used, the diagnosis required laprotomy with biopsy. The clinical manifestations, diagnostic investigations and treatment of the 49 previously reported cases of duodenal tuberculosis are also reviewed.
Segmentation and modeling of visually symmetric objects by robot actions (2011)

Robots usually carry out object segmentation and modeling passively. Sensors such as cameras are actuated by a robot without disturbing objects in the scene. In this paper, we present an intelligent robotic system that physically moves objects in an active manner to perform segmentation and modeling using vision. By visually detecting bilateral symmetry, our robot is able to segment and model objects through controlled physical interactions. Extensive experiments show that our robot is able to accurately segment new objects autonomously. We also show that our robot is able to leverage segmentation results to autonomously learn visual models of new objects by physically grasping and rotating them. Object recognition experiments confirm that the robot-learned models allow robust recognition. Videos of the robotic experiments are also made available.
Two long-wave infrared spectral polarimeters for use in understanding polarization phenomenology (2002)

Abstract : Abstract. Spectrally varying long-wave infrared (LWIR) polarization measurements can be used to identify materials and to discriminate samples from a cluttered background. Two LWIR instruments have been built and fielded by the Air Force Research Laboratory: a multispectral LWIR imaging polarimeter (LIP) and a full-Stokes Fourier transform infrared (FTIR) spectral polarimeter (FSP), constructed for higher spectral resolution measurements of materials. These two instruments have been built to gain an understanding of the polarization signatures expected from different types of materials in a controlled laboratory and in varying field environments. We discuss the instruments, calibration methods, general operation, and measurements characterizing the emitted polarization properties of materials as a function of wavelength. The results show that we are able to make polarization measurements with a relative accuracy of 0.5% degree of polarization (DOP) between two different instruments that are calibrated with the same techniques, and that these measurements can improve the understanding of polarization phenomenology.
Mathematical Model for Predicting Coated-Particle Behavior (1966)

A mathematical model for investigating the irradiation behavior of pyrolytic-carbon-coated fuel microspheres has been formulated. The model can be used to study the influence on coated-particle life of a number of design parameters, such as fuel particle density, number of coating layers, and coating thickness, density, and strength.For typical two-layer coated particles, the model predicts two modes of coating failure: 1) failure initiated at the inner coating surface from the combined effects of fuel swelling, fission-gas pressure, and outer coating shrinkage; and 2) failure initiated at the outer coating surface resulting from anisotropic thermal expansion and fast-neutron damage to the pyrolytic carbon structure.To assure long-term irradiation stability, a coated-particle design must incorporate: 1) free volume to accommodate fission gas and fuel swelling; and 2) an outer coating material that exhibits small dimensional changes under fast-neutron irradiation.
Organic/inorganic double-layered shells for multiple cytoprotection of individual living cells (2014)

The cytoprotection of individual living cells under <i>in vitro</i> and daily-life conditions is a prerequisite for various cell-based applications including cell therapy, cell-based sensors, regenerative medicine, and even the food industry. In this work, we use a cytocompatible two-step process to encapsulate <i>Saccharomyces cerevisiae</i> in a highly uniform nanometric (<100 nm) shell composed of organic poly(norepinephrine) and inorganic silica layers. The resulting cell-in-shell structure acquires multiple resistance against lytic enzyme, desiccation, and UV-C irradiation. In addition to the UV-C filtering effect of the double-layered shell, the biochemical responses of the encapsulated yeast are suggested to contribute to the observed UV-C tolerance. This work offers a chemical tool for cytoprotecting individual living cells under multiple stresses and also for studying biochemical behavior at the cellular level.
PHRITTS - a text-to-speech synthesizer for the German language (1993)

PHRITTS is a text-to-speech synthesizer consisting of a grapheme-to-phoneme conversion, an accentuation, a duration control, an intonation contour generator, and a speech synthesizer based on diphones. After some text preprocessing the grapheme-to-phoneme conversion performs a moiph decomposition. For the rule-based conversion of the resulting morphs a special compiler is used. A word class assignment is made for the following focus-accent-based accentuation, which provides locations for pitch accents and phrase boundaries, followed by a simple context dependent calculation of the phoneme durations. The intonation contour is calculated from the accent pattern using rules derived from natural German speech. It consists of triangular or trapezium shaped pitch moves, placed on a simple pitch declination. They are calculated by linear interpolation in the logarithmic frequency domain. The diphone synthesis is based on 1573 German diphones, extracted from nonsense words spoken with a constant monotonous pitch, which makes it possible to directly concatenate the diphones by interpolation in the time domain, after calculation of the optimal phase at diphone boundaries. Pitch and duration are manipulated using a TD-PSOLA technique. Compared to an existing LPC-based synthesizer version, TD-PSOLA results in much more natural speech. The TTS-synthesizer is written in C-Code and runs in real time on a standard 486 PC with a DSP-board for AD-conversion. Keywords: German text-to-speech synthesis, accentuation, intonation, diphone synthesis
Evaluating real-time Java features and performance for real-time embedded systems (2003)

This paper provides two contributions to the study of programming languages and middleware for real-time and embedded applications. First, we present the empirical results from applying the RTJPerf benchmarking suite to evaluate the efficiency and predictability of several implementations of the real-time specification for Java (RTSJ). Second, we describe some of the techniques used to develop jRate, which is an open-source ahead-of-time-compiled implementation of RTSJ we are developing. Our results indicate that RTSJ implementations are maturing to the point where they can be applied to a variety of real-time embedded applications.
Influence of initial hand and target position on reach errors in optic ataxic and normal subjects (2007)

Recent neurophysiological studies suggest that reach planning areas in the posterior parietal cortex encode both target and initial hand position in gaze-centered coordinates, which could be used to calculate a desired movement vector. We tested how varying gaze, target position, and initial hand position affected reach errors in two left unilateral optic ataxia patients with right PPC damage and seven neurologically intact controls. Both controls' and patients' reaching errors revealed an influence of target position in gaze-centered coordinates; however, both patients' mean errors were offset toward the left, with greater errors when the target was in their left visual field, consistent with the damage to the right PPC. Control subjects also showed a large quasi-independent shoulder-centered influence of target position. This effect was much less present in patient C.F., who had more medial damage to the PPC. In contrast, for patient O.K., who had more lateral PPC damage, the shoulder-centered effect was larger and interacted with the gaze-centered influence of target position. All subjects' errors also revealed a shoulder-centered influence of the initial hand position, with larger influences on the patients' reaching errors. Both patients also showed an interactive influence of the shoulder-centered and gaze-centered initial hand positions. These results suggest that the target and the hand are compared at more than one level in the visuomotor pathway in multiple reference frames, and these comparisons are then integrated. Depending on the location of the damage within the PPC, these comparisons are disrupted, changing the relative influence of hand and target position in different reference frames on the final reaching movement.
An analysis of the determinants of family planning volunteer workers' performance in Iloilo City. (1996)

This report analyzes data from a survey of 106 Barangay (village) Service Point Officers (BSPOs) associated with the City Population Office and 106 Barangay Health Workers (BHWs) associated with the City Health Office to compare the family planning (FP) service delivery performance of these voluntary workers in Iloilo City in the Philippines and to quantify the effects of the factors which influence their performance. Both the BSPOs and the BHWs assist in the delivery of health and FP services at the grassroots level. The survey data were supplemented with interviews with key informants, focus group discussions with married couples of reproductive age, clinic records, and observations of the BSPOs and BHWs at work. The analysis compared the sociodemographic characteristics of the two groups; the recruitment procedures followed (if any); FP training; actual FP-related work; involvement in community organizing; incentives received; supervision of the volunteers; attitude towards their work; FP knowledge, attitude, and practice; time allocated to FP activities; number of clients served; and number of clients counseled. Correlation analysis of factors influencing volunteer performance indicated that FP training had the largest positive influence on FP activities. The output of the workers was also positively affected by the amount of time spend in FP activities and by their involvement in community organizing. The commitment of the workers had a significant impact on the number of clients they resupplied with contraceptives. Variation in the FP performances of the two groups was caused by the fact that delivery of FP services is a major role of the BSPOs and only one of many responsibilities of the BHWs. These findings reinforce the planned restructuring of Iloilo City's FP program which would once again designate the Population Office as the lead agency. Increasing the knowledge of these volunteers about the side effects and contraindications of various methods should have a positive effect on continuation rates. Recruitment of volunteers should be based on the individual's level of interest and commitment.
Towards an Understanding of the Carbon‐Carbon Bond (1980)

Abstract In this essay, the classical question of “the influence of the number and kind of substituents on the strength of the CC bond”, is pursued with the modern tools of contemporary physical organic chemistry. Based on the work of Karl Ziegler , the products and kinetics of thermolysis of a large number of highly branched aliphatic hydrocarbons and phenyl‐ or cyano‐substituted derivatives were investigated. For each class of compounds, a linear relationship was found between the free enthalpy of activation of the homolytic cleavage of the weakest CC bond and the strain energy in the ground state. These relationships permitted a quantitative separation of steric and electronic effects on the cleavage of CC bonds. The influence of the size of the substituent groups on bond angles, bond lengths, and the conformational behavior of model compounds was studied by means of experimental structure determinations and force field calculations. CC bond lengths up to 164 pm, bond angles at tetracoordinate carbon as large as 126°, and unusual eclipsed and gauche preferred conformations were found.

Mass spectral characterization of tetracyclines by electrospray ionization, H/D exchange, and multiple stage mass spectrometry (2002)

Electrospray ionization (ESI) and collisionally induced dissociation (CID) mass spectra were obtained for five tetracyclines and the corresponding compounds in which the labile hydrogens were replaced by deuterium by either gas phase or liquid phase exchange. The number of labile hydrogens, x, could easily be determined from a comparison of ESI spectra obtained with N2 and with ND3 as the nebulizer gas. CID mass spectra were obtained for [M + H]+ and [M - H]- ions and the exchanged analogs, [M(Dx) + D]+ and [M(Dx) - D]- , and produced by ESI using a Sciex API-III(plus) and a Finnigan LCQ ion trap mass spectrometer. Compositions of product ions and mechanisms of decomposition were determined by comparison of the MS(N) spectra of the un-deuterated and deuterated species. Protonated tetracyclines dissociate initially by loss of H2O (D2O) and NH3 (ND3) if there is a tertiary OH at C-6. The loss of H2O (D2O) is the lower energy process. Tetracyclines without the tertiary OH at C-6 lose only NH3 (ND3) initially. MSN experiments showed easily understandable losses of HDO, HN(CH3)2, CH3 - N=CH2, and CO from fragment ions. The major fragment ions do not come from cleavage reactions of the species protonated at the most basic site. Deprotonated tetracyclines had similar CID spectra, with less fragmentation than those observed for the protonated tetracyclines. The lowest energy decomposition paths for the deprotonated tetracyclines are the competitive loss of NH3 (ND3) or HNCO (DNCO). Product ions appear to be formed by charge remote decompositions of species de-protonated at the C-10 phenol.
일반논문 : 『천부경』 의 "천(天),지(地),인(人)"에 관한 연구 (2008)

우리 민족에게는 중국으로부터 불교와 유교 및 도교가 들어오기 시작한 삼국시대 이전에 이미 찬란한 문화와 역사가 있었으며 독자적인 사상이 있었다. 그 내용을 『천부경』 의 ``天·地·人``을 통해 알아볼 수 있다. 『천부경』의 ``天·地·人``은 우주 만물의 근원적 본체인 ``一``에서 나뉜 우주의 가장 기본적 구성 요소라고 할 수 있다. 이 ``天·地·人``을 우주생성론적으로 볼 때, 天이 첫 번째로 나오고, 地가 두 번째로 나왔으며, 人이 세 번째로 나왔다고 할 수 있다. 또한 우주구성론으로 보면 天속에 다시 ``天·地·人``이 있고, 地속에도 ``天·地·人``이 있으며, 人속에도 역시 ``天·地·人``이 있다는 것이다. 중국의 『주역』과 『태평경』에도 ``天·地·人``이 나오지만, 대체로 음양의 관념을 바탕으로 한 삼재(三才)를 말한다. 또한 『주역』과 『태평경』의 ``天·地·人`` 속에는 인격적 개념이 포함된 경우도 있다. 이와 같이 『천부경』 의 ``天·地·人``은 한국 사상을 중국 사상과 구별해주는 중요한 자료이다. 따라서 우리 고유 사상의 精髓가 담 겨 있는 『천부경』 이야말로 우리 문화가 중국의 亞流가 아님을 입증할 수 있는 귀중한 문화유산이다.
Cell Cycle Control of DNA Replication by a Homologue from Human Cells of the p34 <sup> <i>cdc2</i> </sup> Protein Kinase (1990)

The regulation of DNA replication during the eukaryotic cell cycle was studied in a system where cell free replication of simian virus 40 (SV40) DNA was used as a model for chromosome replication. A factor, RF-S, was partially purified from human S phase cells based on its ability to activate DNA replication in extracts from G1 cells. RF-S contained a human homologue of the Schizosaccharomyces pombe p34cdc2 kinase, and this kinase was necessary for RF-S activity. The limiting step in activation of the p34 kinase at the G1 to S transition may be its association with a cyclin since addition of cyclin A to a G1 extract was sufficient to start DNA replication. These observations suggest that the role of p34cdc2 in controlling the start of DNA synthesis has been conserved in evolution.
Pichia pastoris Aft1 - a novel transcription factor, enhancing recombinant protein secretion (2014)

The methylotrophic yeast Pichia pastoris is frequently used for the production of recombinant proteins. However, expression levels can vary depending on the target protein. Allowing for simultaneous regulation of many genes, which may elicit a desired phenotype like increased protein production, overexpression of transcription factors can be used to overcome expression bottlenecks. Here, we present a novel P. pastoris transcription factor currently annotated as Aft1, activator of ferrous transport. The promoter regions of key secretory P. pastoris genes were screened for fungal transcription factor binding sites, revealing Aft1 as an interesting candidate for improving secretion. Genome wide analysis of transcription factor binding sites suggested Aft1 to be involved in the regulation of many secretory genes, but also indicated possible novel functions in carbohydrate metabolism. No Aft binding sites were found in promoters of characteristic iron homeostasis genes in P. pastoris. Microarrays were used to study the Aft1 regulon in detail, confirming Aft1 involvement in the regulation of carbon-responsive genes, and showing that iron regulation is dependent on FEP1, but not AFT1 expression levels. The positive effect of AFT1 overexpression on recombinant protein secretion was demonstrated for a carboxylesterase from Sphingopyxis sp. MTA144, for which secretion was improved 2.5-fold in fed batch bioreactor cultivations. This study demonstrates that the transcription factor Aft1 can be used to improve recombinant protein secretion in P. pastoris. Furthermore, we discovered possible novel functions of Aft1 in carbohydrate metabolism and provide evidence arguing against a direct role of Aft1 in P. pastoris iron regulation.
