Goal: to increase the speed and efficiency of research and adjustment of the psychophysiological state of a person by developing a method of matching and detecting influences of relaxing pictures for human psychophysiological state adjustment. A review of the main provisions of research, data collection, and adjustment of the psychophysiological state of humans. The main problems of processing the collected data for the analysis, matching of relaxing pictures are described and the necessity in the development of methods for matching and detecting influences on a psychophysiological condition of relaxing pictures is defined. A method of matching relaxing pictures for correction of the psychophysiological state of a human on the basis of neural networks is offered. The application of the proposed method allows you to submit a set of parameters: color preference, birthday, favorite color, subjective feelings and get a relaxing picture for sessions to correct the psychophysiological state. A method for detecting influences on the psychophysiological state of a person is proposed, which allows, due to a flexible configuration mechanism for plotting, to build various parameters of research of the psychophysiological state of a person and identify their dependencies and influences on a person. The software of the offered methods of matching and detecting influences of relaxing pictures on a condition of the human which increases the efficiency of work of psychologists on the research of a psychophysiological condition of the person is developed. A software startup project has been developed and an analysis of potential customers and the market has been conducted, which shows that the market is still free from analogs of such a product, but needs it.

Active force generation is an important class of out-of-equilibrium activity in cells. These forces play a crucial role in vital processes such as tissue folding, cell division and intracellular transport. It is important to determine the extent of such nonequilibrium activity during cellular processes to understand cell function. Here we present a framework for measuring nonequilibrium activity in biological active matter using time reversal asymmetry based on the Kullbeck-Leibler Divergence (KLD), also known as relative entropy. We estimate the KLD from a stationary time series using a k-nearest neighbors estimator, comparing the time-forwards process to the time-reversed process Using time series data of probe particles embedded in the actin cortex, we establish a lower bound for the entropy production of cortical activity. Our results demonstrate a reliable way to measure the breaking of detailed balance in mesoscopic systems.

Full textLikhetsanalys mellan dokument är ett välutforskat område. Med fokus istället på motsatsen, hur kan vi försöka definiera och särskilja skillnaderna mellan dokument? Detta projekt försöker undersöka om skillnader mellan dokument kan detekteras samt kvantifieras baserat på deras semantiska kvalitéer. Vi föreslår en metod för kvantifiering av skillnader genom att applicera tf-idf baserade modeller tillsammans med analysmetoder för lemmatisering och synonymextrahering, i kombination med utilitetsrankningsalgoritmer. Metoden implementeras och testas. Resultaten visar att metoden har potential men att det krävs ytterligare studier för att fullt ut avgöra till vilken grad den skulle kunna vara praktiskt användbar. En sådan metod skulle dock kunna erbjuda stora fördelar för ett flertal olika discipliner, där automatisk skillnadsdetektering skulle kunna ersätta felbenägen manuellt arbete gällande dokumentationshantering, samt också fylla andra förmånliga syften som t.ex. att kunna erbjuda automatgenererade skillnadssammanfattningar.

Full textThe response of foals to the stress of weaning was examined in terms of
a behavioral protocol and the responses of plasma ascorbate, serun1 cortisol,
and the serum cortisol response to an ACTH challenge. Behavior scores (1 to
10) as an index of stress were assigned to each foal daily, with high scores
indicating less stress and better adjustment. The experimental plan was a 2 X 2
factorial of pre-weaning diet and stall weaning method. Foals were raised on
pasture supplemented with hay and a pelleted concentrate (PHC) or pasture
supplemented with hay only (PH). Foals were placed in stalls singly or in pairs
for weaning. Gender influences were also examined. The foals exhibited
characteristic behavioral and physiological responses to the social dislocative
stress of weaning. Behavior scores were lower in paired than in single foals (p =
.008) and tended to be lower in PH than PHC foals (p = .15). No differences in
post-weaning plasma ascorbate concentrations were found among treatments.
Responses of serum cortisol to an ACTH challenge were lower in PH than PHC
foals (p = .001) and in paired than single foals (p = .058), and lower responses
were taken to represent adrenal depletion arising from stress. Behavior scores
were positively correlated with the response of serum cortisol to ACTH. Both
behavioral data and the serum cortisol response to ACTH indicate that foals
were better able to cope with weaning stress when supplemented with
concentrate prior to weaning and when weaned singly.

The purpose of this study is to use electrical resistivity tomography (ERT) method to survey the underground abnormal composition through different level of electrical resistivity. By applying electrical current through the soil and measuring the specific resistance of the underground soil, the resistance data of solid or rock can be analyzed. Thus, the underground profile can be obtained due to the difference resistivity of soil deposit. Two sites are investigated in this study. The first site is to explore the soil profile of the two dams of a new under construction reservoir, which used back-filled, rolled, and compacted methodology of construction. The results show that there are the same characteristics as the reservoir’s survey report. The second site is located at the north side of the civil engineering building in the National Cheng Kung University. The main purpose of this exploration is to determine the depth of foundation pile. After applying three different patterns of examinations, i.e. the Wenner array, Schlumberger array, and ipole-Dipole array, the results show that the depth of the foundation pile is not easy to be detected. This may be due to the soil profile under both sides of survey line is different. East side is a back-filled material, while the west side is pure soil deposits. In the measurement, the different metal electrodes, one is rebar (the east side) while the other is stainless steel (the west side), were used. The data of specific resistance of the back-filled material on the east side of the survey line is greater than those of the other side. For the purpose of comparison, the same soil site was used with different metal electrodes. The result shows that the survey depth is shallow as the rebar is used.

Damage assessment of structure is an important task for the maintenance and management of bridge system. An influence line type inspection technique is developed in this thesis. The displacement influence line at a point in the span of a beam structure is measured first. Through the second derivative of this displacement influence line with respect to the spatial variable along the beam, both the locations and the severities of crack damage can be clearly identified. The feasibility and accuracy of this damage assessment technique are verified both theoretically and numerically of beams with various prestress states. The second Castigliano’s theorem is applied to calculate the displacement influence line of beams with various prestress conditions and damages. Due to the measurement noise, the capability of damage identification from experimental data is not as impressive as it shown in the numerical and theoretical investigations. However, this scanning type damage assessment technique by the influence line response provides a possible manner to improve the inspection efficiency if the effect from measurement noise can be reduced in the future.

Fluoroquinolone (including Danofloxacin, Ofloxacin and Enrofloxacin) are widely used in controlling gram negative bacterial and mycoplasmal infectionsof livestock in Taiwan. Howere,the problem of drug residues will arise in meat hygiene if the farmers ignore the withdrawing peroid of these drugs before slaughtering their livestock. In this study, we determined the optimum conditionfor the application of high performance liquid chromatography(HPLC) to the analysis of drug residue in meat and withdrawing period. In the first part of our study, muscles and livers were taken from chickens experimentally treatedwith Danofloxacin, Ofloxacin and Enrofloxacin in drinking water at dosage of 10,10 and 5 mg/kg wt./day, respectively. Samples from the chickens of the three treated groups were pretreated with 0.5M dipotassium hydrogen phosphate solution, extracted with dichloromethane and then fractionated in 1% phosphobic acid.The last fraction was assayed for traces of the drug by HPLC. By comparing the results of the three tested fluoquinolones, the appropriate withdrawing period of Danofloxacin, Ofloxacin and Enrofloxacin were found to be 3, 7 and 9 days,respectively. These periods were the same as those recommended by the drug manufacturers. Since the drug residues were found to be below 0.001ug per gramof the samples tested, it is thought that the meat will be safe for human comsumption. In the second part of this study, of the three hundred muscle samplescollected from a commercial slaughterhouse that were assayed for drug residue,fluoroquinolones were observed in 104 muscles(34.67% of tested samples) at concentration ranging from 0.008 to 0.0122 ug/g. The number of the farms with chickens positive for drug residues were 11 of 15 farms surveyed(73.33%). Theestablishment of this drug residue assay method will make it possible for assaying routinely a large number of samples at the slauterhouse. In addition, our resultson the withdrawing period and the testing of market samples will provide the Department of Agriculture r reference for improving meat hygiene and the strengthening of public health.

We apply the subgroup identification method of Loh et al. (2015) to non-medical data for detecting zones of distributional differences. The subgroup identification method can find subgroups that show significant treatment effects. We apply the same procedure and use bootstrap confidence interval with the Bonferroni correction (Johnson and Wichern, 2014) for finding zones of distributional differences among years in the arson fire data. The analysis shows that this method can successfully detect zones of distributional differences among 4 years. Furthermore, it is feasible to adopt these methods in other fields.

The Meishan fault is an earthquake fault which was displaced in the 1906 Meishan earthquake (M=7.1). The earthquake induced severe damages and killed 1,258 people. However, it is also signified as the first instrument-recorded and well-documented earthquake in Taiwan by civilized technologies. The fault was a right-lateral and slight-thrust oblique fault (1~2 m displacement) trending in the N75E direction. The northern side was lifted near Meishan and it changed to the southern side raised remote from Meishan. We revisit the Meishan fault to prepare for its 100th anniversary in 2004-2005. A relatively advanced and detailed reflection seismic survey was carried out to find new evidences which may lead better understanding of the peculiar behaviors of the fault. After collecting and analyzing 4 seismic profiles across the fault, we realize that it needs to put the Meishan fault in the regional geological framework to identify its role and meaning. The earthquake was initiated near Meishan where the fault intersected the Hsiaomei anticline by 50 degrees. There is also another significant thrust (the Chiuhsiungken fault, NS orientation) sited to the east. The merger of these three systems claims the focus of the earthquake. When the earthquake was set off, the northern side moved to the east and was hindered by the Hsiaomei anticline and the Chiuhsiungken thrust, thus was uplifted. On the other hand, far from Meishan to the west end, the southern side was relatively free to move and even uplift. An interesting compressive bending type of ‘flower structure’ was found along the fault trace given by Omori (1907). The rupture amplitudes decay quickly toward the western end, where is the Chungcheng university. The segmentation of fault occurred here and a branch (the Chenchuliaw fault) resumed. The investigation of the Meishan fault should be concentrated around Meishan, not to the western end. More investigations need be emphasized near the town of Meishan.

Phishing attacks attract users to visit fake website to steal their personal information. Most phishing detection approaches adopt Uniform Resource Locator (URL) blacklists or phishing website features as a detection character to cope with phishing attacks. The existing approaches of using URL blacklists cannot detect the new phishing attacks because they are not existed in the blacklists. Similarly, the existing feature-based methods suffer high false positive rates and this leads to an inadequacy in the online transactions. To solve these problems, we use the feature of legitimate websites to detect phishing attacks to improve false negative rates and false positive rates.

Detecting the Hukou Fault by Shallow Seismic Reflection Method Liang-An Lin ABSTRACT The Hukou fault is located at the northern border of the Hukou terrace. It runs almost in the east-western direction. Physiographically, the fault looks like a scarp along the terrace’s boundary and is generally attributed as an active fault. The purpose of this study is to detect the Hukou fault and the structures in its vicinity using the shallow seismic reflection method. Several long-range seismic lines (400 m long) are distributed perpendicular to the fault trace with the visible seismic images down to the depth of 700 meters. Besides this, we also used five short-range seismic lines across the Hukou anticline, from the edge of the terrace to Tienzuhu, to investigate the structure of this fault-related anticline. After carefully reserving the characteristics of each reflector, we are able to correlate different layers on different seismic profiles. On the seismic profiles, we find that all structure layers vary quite smoothly. The layers bend upward, but not broken at the suspected place of the Hokou fault. It seems that the scarp represents a boundary of curved stratum (i.e. part of an anticline), not a presentation of an actual fault. Furthermore, the positions where the structures bend are shifted to the east from the cliff of the terrace by about 50 m. The young Tienzuhu Formation has covered this shifted area. Thus, we tend to propose that a blind thrust fault might hide at the bottom and it makes the ‘fault-bend’ fold structure. We also found that the Hukou anticline is an asymmetric anticline. It is steeper in the north flank than in the south flank. The axis is extended toward the southeast of Pingchen and becomes closer to the fault with decreasing uplift. One important seismic images are obtained on the plane area where the young lateritic terrace deposits is obviously disturbed by the tectonic stress. Because of this, we intend to propose that the potential risk of the fault activity might not be ignored.

Taiwan is located on the converging boundary of Eurasian and Philippine Sea plates, it is one of the most rapidly uplifting orogeny in the world. In this area, the pattern of the plate collision is occurred between two subducting systems, the geological structure here is quite complicate. So there are many models of the tectonic collision, from the typical thin-skinned thrust to the lithospheric collision, or some other models as uplifting of buoyancy. In this study, we attempt to describe the Moho depth beneath Taiwan by using amount of data from the project of Taiwan Integrated Geodynamic Reseach(TAIGER), and expect for the results can make some improvements to the construction of tectonic collision patterns of Taiwan orgoeny. The land-explosion of TAIGER project was carried out from Feb to March on 2008, and it includes:1) 3 W-E line linear seismic arrays which were consisted of 800 Texans with spacing in 200 meters at northern, middle and southern Taiwan; 2) 2 N-S linear seismic arrays which were consisted of seismometers with spacing in 6 kilometers at middle and eastern Taiwan; 3) 10 explosion sources with the dynamite from 750~3000 kilograms which were set at the depth of 80 meters in the hole with an aperture of 12 inches, and the sources were located on the northern and southern W-E line from the west to the east. We get 6 kinds of data from this experiment, including:1) the wide-angle reflections of Texans; 2) the N-S seismometer arrays; 3) the seismic network of Central Weather Bureau(CWB) and Institute of Earth Science(IES); 4) the seismic array of Reftek 130(RT130) from IRIS in TAIGER project; 5) the short period of Ocean Bottom Seimometer(OBS) array in the Taiwan Strait; 6) the temporary seismic array in mainland China. In this study, we handle the data from 3 W-E transects, 2 N-S transects and Taiwan Strait, and simulate the structure model from the first arrival time and more obvious reflections of these data by Ray-tracing method. The preliminary results are as follows:1) It is a standard layered structure beneath western Taiwan and the thickness of crust is 30 kilometers; 2) The crust thickens and becomes more than 40 kilometers in the mountain area, but it is narrow and deep here; 3) The structure beneath Hsuehshan Range and Central Mountain Range are different; 4) There are some boundary faults as deep as to the lower crust, especially the Li-shan fault; 5) The distribution of the Moho depth is basically thicker in the north, shallower in the south and getting deeper and deeper from the west to the east, but finally getting shallower rapidly in the area of Coast Range; 6) The Moho depth is shallower than 30 kilometers in the Peikang Height and deeper than 32 kilometers at the coast line of Fujian, there is no bulge in Taiwan Strait.

Imazapyr is a major herbicide used on upland fields in Taiwan. It shows strong herbicidal activity at a low application rate against a wide range of weeds. Inadequate use of imazapyr could result in phytotoxicity of non-target plants due to its strong herbicidal activities on most species and relative longer residual activity. This research was conducted to investigate the bioactivity of tested herbicide in soil and the phytotoxicity potential of soil leachates on non-target crops. A bioassay method using radicle growth inhibition of cucumber and lettuce was developed to determine the concentration of imazapyr in soil and soil leachates. The method involved planting pre-germinated seeds of tested crops in soil treated with imazapyr or in filter papers soaked in 400 ml soil leachates. The radicle length of germination after 7, 14 and 21 days treatment was measured individually, dose-response relationship between radicle elongation and 500 ppm imazapyr was existed, but not between hypocotyl elongation and imazapyr concentration. When imazapyr was detected in soil leachates by HPLC, an apparent inhibition in radicle length of cucumber and lettuce by high concentration of imazapyr was observed. Differential sensitivity of tested plants to imazapyr was quantified by determining the herbicide rates required to reduce radicle length 20% and 50% (I20 and I50 values). Data indicated that sorghum and cabbage were generally more sensitive than other plant species tested. Cucumber and tomato were intermediate sensitivity, and mungbean and lettuce were the most tolerant species tested. Soil treated with imazapyr and its leachate affected negatively on radicle elongation. However, the soil leachate caused less inhibition than the tested soil. The suppression effects of treated soil and leachate on radicle elongation were similar, indicating that imazapyr may leach from the soil into the soil water. In the field experiment, the soil was sprayed with 750 g ha-1, 1.5 kg ha-1 and 3 kg ha-1 imazapyr, individually. The soil samples was collected after treatment. Imazapyr residue in soil sample was analyzed by HPLC and bioassay method. The residue of imazapyr in soil decreased as spraying time increase. The degradation rate of 3 kg ha-1 imazapyr in soil was more rapid than 1.5 kg ha-1. The degradation rate of imazapyr in soil decreased in cold and less rainy season. The tendency of sensitivity of three crops to imazapyr residual in soil was almost the same between the hot and cold season. The sensitive degree of three crops to imazapyr residual in soil sequentially was cabbage,cucumber and mungbean. In conclusion, imazapyr residue in soil and rate of radicle elongation in hot season was more less than cold season by HPLC analysis and bioassay method. Cabbage could be used as an indicator crop for detecting imazapyr residue in field soil under the rainy hot season, otherwise cucumber was recommended as an indicator crop under dry cold season.

Generally, the estimation and prediction methods of E-bike’s battery are easily impacted by aging, effective measurement also reliedon on high-end commercial impedance spectroscopy. The method that can be used on battery resistance and state of charge (SOC) detecting is described, which is based on specific battery chemistries and focused on the internal impedance without complex chemical model. By using switched circuit, corresponding parameters can be measured. The method uses Labview and DAQ-6008 to modulate sinusoidal signals at 100 Hz, which is converted to a constant-current excitation signal. By measuring the response of voltage, the battery internal resistance can be found. The relationship between cell impedance and SOC is also identified.
