Design analysis for the two-stage alpha, beta, gamma estimator

The transfer functions and variance reduction ratios of the two-stage alpha , beta , gamma -bar estimator are compared with those of the standard alpha , beta and alpha , beta , gamma filters. In the two-stage alpha , beta , gamma -bar estimator, position and velocity are tracked in the first stage, a standard alpha , beta filter, and the acceleration is tracked in the second stage, which is a standard, single-gain gamma -bar filter. The output of the acceleration filter can be used to adjust the estimates of the alpha , beta filter when a bias is detected in its tracking residuals. The transfer functions for the position, velocity, and acceleration estimates of the two-stage alpha , beta , gamma -bar estimator are derived, along with the variance reduction ratios. <<ETX>>
Development of performance evaluation scale for housekeeping staff in the accommodation companies: Ankara sample

In today’s world where it is an undisputed fact that one of the most important competitive sources for enterprises is qualified labor force and a valid performance evaluation system is needed to manage this power in enterprises. This research has been planned and conducted in order to develop a sector specific measurement tool for the housekeeping staff which works in the hospitality business sector. For this purpose, firstly a literature review has been made and a conceptual framework on performance evaluation and housekeeping has been tried. Then, development of expressions, structuring of the scale and data analysis were completed by applying the scale development steps. In this process, face-to-face interviews were conducted in order to determine the expressions. The data obtained from the research were analyzed with confirmatory and exploratory factor analyzes and structural equation model. As a result of the analyzes, it was concluded that a valid and reliable scale was developed to evaluate the performance of housekeeping staff. In addition, factors affecting individual performance were also investigated and statistically significant relationships were found between organizational commitment, perceived stress and freedom of decision and individual performance.
Regulated by IL-12 Expression of L-Selectin on Th1 Cells Is

L-selectin has become established as a key molecule in the recirculation of naı¨ve T cells from the blood to peripheral lymph nodes, yet little is known about its role in the migration of effector or memory cells. While differentiating naı¨ve CD4 1 T cells into Th1 and Th2 subsets in vitro, it was noted that L-selectin levels were maintained on the Th1 subset of cells. The expression of L-selectin on the Th1 cells appeared to be dependent on the presence of IL-12. Th2 cells, differentiated in the absence of IL-12, failed to maintain L-selectin expression. Coculture with IL-12, IL-18, IL-4, TNF- a , or IFN- a , - b , or - g demonstrated a dependence on IL-12 alone for L-selectin expression. In addition, the inclusion of heat-killed Listeria monocytogenes in the cultures also maintained L-selectin expression on the Th1 cells. In all cultures, the maintenance of L-selectin on the T cell surface could be blocked by the inclusion of anti-IL-12 Abs. Analysis of the mRNA levels for L-selectin in T cells, differentiated in the presence or absence of IL-12, showed that the cytokine appears to exert its effect on L-selectin at the transcriptional level. Given the key role played by IL-12 in the differentiation of naı¨ve T cells into the Th1 subset, the observation that IL-12 can also regulate L-selectin expression has implications for the migration of Th1 effector cells both through the lymphatic system and to sites of inﬂammation.

properties across age groups.

Valid and reliable measures are needed to better understand the relationship between physical activity and crime. This paper provides a comprehensive psychometric evaluation of measures developed in the Safe and Fit Environments (SAFE) Study to assess a crime-PA conceptual framework. In addition to assessing the basic psychometric properties of each measure (e.g., variable distributions [item/scale level], internal consistency reliability), this study formally examined the measurement validity and invariance of measures across four age groups using confirmatory factor analysis. The sample (n = 2173) included 336 Adolescents (aged 12 – 17), 532 Young adults (aged 18 – 39), 838 Middle Age Adults, and 467 Older Adults (aged 66 + ). The psychometric evaluation of (sub)scales showed consistent factorial validity and internal consistency reliability across the majority of the measures and across the four age groups. Specifically, 14 of the 17 measures displayed statis- tically and practically significant factor loadings and internal consistency values in the overall sample and across the age groups. The pattern of correlations for each (sub)scale with other (sub)scales/indexes largely did not exhibit redundancy across measures. The findings expanded upon the test – retest reliability evaluation reported in Patch et al. (2019), and clarified key aspects of the construct validity of these indicators. The latter bodes well for potential utility of these indicators in future predictive models.
Shape Recognition and Center of Mass – How Educational Backgrounds in Engineering and Art & Design Affect Aesthetic and Stability Evaluations towards Self-supporting Shape Objects –

: How do peoples’ educational backgrounds affect peoples’ visual estimations of the physical stability and center of mass of objects? To address this, we tested peoples’ aesthetic and stability evaluations of inclined triangular shapes among those with different educational backgrounds, specifically in engineering and art & design. The results showed that people prefer objects that appear stable; however, art & design students tend to emphasize the beauty of unstable objects. Additionally, participants linearly estimated objects’ stability based on the visual information for its center of mass, with this being affected by one’s educational background as well as any present geometric-optical illusions. Engineering students tended to more severely evaluate the instability of objects, while those with an art & design background demonstrated a more flexible mindset — they evaluated similar trends as the engineering participants for unstable stimuli, but, for apparently stable stimuli, they had similar evaluation trends to those of general students.
Dramatic change of the recurrence time and outburst parameters of the intermediate polar GK Persei

This analysis has shown that the intermediate polar GK Per experienced a very striking evolution. Its outbursts became wider and brighter in the last five decades. These changes were accompanied by striking variations of the recurrence time T C , from 385 days within the years 1948–1967 to 890 days in 1970. Nowadays, T C displays a strong trend of linear increase. Decrease of irradiation of the disk by the WD, combined with the decrease of viscosity, offers a plausible explanation. It is argued that variations of the mass transfer rate are unlikely to play a major role. The morphology of the outburst light curves in the optical and the X-ray region is also studied. The decay branch in the optical remains remarkably similar for all the events while the largest changes of the light curve occur in the rising branch. This can be explained if the thermal instability may start at different distances from the disk center. The quiescent level of brightness does not display any secular trend in recent decades but a wave on the time scale of about 30 years with the full amplitude of 0.3 m v , probably due to activity of the cool star, is detected.
Classification of Encrypted QUIC Network Traffic

Today, more and more organizations are setting up infrastructures to encrypt their network traffic. As a result, a modern, robust, and lightweight encryption scheme is required. As an example for this, QUIC, a novel transport layer encryption protocol, was developed by Google. QUIC is designed to address TCP issues, while running over UDP, and thus, unlike TCP, it does not require an overhead to keep track of its connections. Nonetheless, encryption reduces the amount of information available to network traffic monitoring tools, necessitating the development of new extraction methods to keep up with the growing amount of such encrypted traffic. In this thesis, learning-based models are developed that can distinguish between various Google services that run on top of QUIC. Also, the most relevant features of encrypted QUIC network traffic are determined and the classification performance of the new feature vector is evaluated using various supervised ML algorithms. According to the results, the proposed solution achieves good accuracy, precision, recall, F1 score, and ROC AUC scores. Furthermore, the explainability aspect is adressed in order to comprehend patterns learned from data and then the feature importance is re-evaluated using such adaptive techniques.
l e Conﬁdence and Career Choices: An Experiment ∗

Conﬁdence is often seen as an important determinant of success. Empirical evidence regarding the causal eﬀect of conﬁdence on choices is, however, sparse. Using a stylized laboratory experiment, we examine the eﬀect of an increase in conﬁdence on two important labor market choices: (i) the amount of ability-contingent earnings risk to take on, and (ii) the subsequent eﬀort choice. We ﬁnd that increased conﬁdence leads subjects to take on more ability-contingent earnings risk. However, eﬀort levels are unaﬀected. Overall, the upward shift in conﬁdence is detrimental for low ability workers due to high baseline levels of conﬁdence. in our subjects’ to exert eﬀort.

Gun muzzle flash detection using a single photon avalanche diode array in 0.18µm CMOS technology

In this study, a CMOS Single Photon Avalanche Diode (SPAD) 2D array is used to record and sample muzzle flash events in the visible spectrum, from representative weapons. SPADs detect the emission peaks of alkali salts, potassium or sodium, with spectral emission lines around 769nm and 589nm, respectively. The alkali salts are included in the gunpowder to suppress secondary flashes ignited during the muzzle flash event. The SPADs possess two crucial properties for muzzle flash imaging: (i) very high photon detection sensitivity, (ii) a unique ability to convert the optical signal to a digital signal at the source pixel, thus practically eliminating readout noise. The sole noise sources are the ones prior to the readout circuitry (optical signal distribution, avalanche initiation distribution and nonphotonic generation). This enables high sampling frequencies in the kilohertz range without significant SNR degradation, in contrast to regular CMOS image sensors. This research will demonstrate the SPAD’s ability to accurately sample and reconstruct the temporal behavior of the muzzle flash in the visible wavelength, in the presence of sunlight. The reconstructed signal is clearly distinguishable from background clutter, through exploitation of flash temporal characteristics and signal processing, which will be reported. The frame rate of ~16 KHz was chosen as an optimum between SNR degradation and temporal profile recognition accuracy. In contrast to a single SPAD, the 2D array allows for multiple events to be processed simultaneously. Moreover, a significant field of view is covered, enabling comprehensive surveillance and imaging.
Reply to the Letter to the Editor Reply to Sidhu and MacGowan

We appreciate Dr Sidhu’s and Dr MacGowan’s interest in our study and their comments regarding this. At the time of submitting the manuscript, we were not aware of the study conducted by Sidhu and O’Kane [1]. It is an interesting study, which we should have referred to in our paper. The results found in this well-conducted randomized trial are in line with our results. The age of the patients does not seem to have an independent major impact on the ability to conduct selfmanagement and the results hereby obtained. Feasibility and good results has been demonstrated both in children (age from 2.2 to 15.6 years) [2] and in older patients (age from 65 to 80 years) [3]. However, self-management can only be offered to selected patients, who are able (both physically and mentally) to manage their own anticoagulation therapy, and this seems relatively independent of age. In our study, we had a narrow therapeutic range (target INR ^0.5); the same as in the study by Sidhu et al. We agree that the result of time within therapeutic INR target range is highly dependent of the therapeutic INR target range. All things being equal, a therapeutic INR target range of 2.0–4.0 will provide a higher time within therapeutic INR target range compared to a therapeutic INR target range of 2.0–3.0. The time within therapeutic INR target range also differs using different methods of calculation. This makes comparison between various studies difficult. Other methods to estimate the quality of treatment exist: the extent of deviation of INR-values from the INR target value, which shows correlation with the number of bleedings and tromboembolism [4]. The incidence of clinical endpoints (major tromboembolism and bleeding events) is the best method of quality assessment, but it requires many patients in order to get a statistically valid result, since the incidence of these complications is relatively rare. Conductions of such studies obviously require significant resources. As described in our paper, we recommend a thorough and structured training. Therefore, we agree with Dr Sidhu et al. in the importance of this, although others have presented good results merely by instructing patients in the function of the coagulometer [5]. Regarding the safety issue: we agree with Dr Sergeant that it is highly important the patient is not ‘left on his own’. The patient should have access to professional support regarding the treatment, and this requires certain demands to the health care system. We agree with Dr Sidhu et al. that the number of potential variables seems fewer in self-management compared to standard management. However, formalized guidelines are needed in to order to minimize the variables in self-management, e.g. the assessment of patient suitability, responsibility of the treatment, medical evaluation, training, exam and internal/external quality control of the coagulometer. These guidelines could be prepared in an international frame, using knowledge and experience from all centers.
TO NON-NORMAL DEPENDENCE STRUCTURES

The Capital Asset Pricing Model arises in an economy where agents have exponential utility functions and aggregate consumption is normally distributed, and gives the prices of assets with payoffs which are jointly normal with consumption. Such assets have normal marginal distributions and have dependence with consumption characterised by a normal copula. Wang has derived a transform which extends the CAPM by allowing pricing of assets in such an economy which have non-normal marginal distributions but still are normal-copula with consumption. Here we set out the stochastic discount factors corresponding to this version of the CAPM and to Wang’s transform, and show how to calculate stochastic discount factors and hence asset prices for assets whose dependence with consumption is non-normal. We show that the impact of dependency structure on asset prices is signiﬁcant.
Model for Supporting Dynamic structure of organization.

—Due to rapid development in cloud computing and integration of new tools that enhances the development in cloud computing application, but cloud computing is in child state so that cloud security is often required. Many organizations want to store their confidential sensitive data in cloud in order to reduce capital expanses. Traditional way is to store data in encrypted format against the untrusted cloud service provider (CSP). The key problem is to maintain different organization structure and establishing unaccess control policy (UCP) for those confidential encrypted data, when users are no longer employee of organization. This paper aims to solve problem for supporting different organization structure and maintain their hierarchy of various users in the organizations, maintain record of employees . Our system is having integrating key feature of Hierarchical attribute based encryption (HABE) and cipher text policy attribute based encryption (CP-ABE) system, so as not only achieved high performance and fine grained access, user revocation scheme when user are not longer employee of organization.
Necrotizing Fasciitis – A Case Report of GBS Infection in a Previously Healthy Woman

This article describes a case of necrotising fasciitis following a procedure of total hysterectomy caused by group B streptococcus in a previously healthy 50 year-old female patient. The patient was readmitted to the hospital in the 7th post-surgical day with a necrotic surgical site infection. Microbiological cultures were collected and Streptococcus agalactiae isolate was further characterized by molecular techniques. Besides of the invasive infection, the patient also developed an abscess in the lumbar region. The treatment consisted of surgical debridement, incision and drainage, a combination of antibiotic courses and hyperbaric therapy. The patient made a full recovery. This was her second episode of postsurgical complications, with the first one occurring in 2011. This is possibly the first report of necrotizing fasciitis in a previously healthy patient caused by GBS in Poland. We would like to open a discussion whether GBS screening before gynaecological procedures should be a standard, since invasive GBS infections play a role not only in Europe but also in the USA.
ANALYSIS FOR EPHEDRINE ALKALOID UTILIZING ISOCRATIC HIGH PERFORMANCE LIQUID CHROMATOGRAPHY

A method to assay ephedrine hemihydrate (ephedrine alkaloid), which has various biological activities, is presented using isocratic high performance liquid chromatography (HPLC). Elution of the analyte is detected with ultraviolet light detector, set at 255 nm. The stock solution of this ephedrine alkaloid was prepared in solvent conditions that consisted of 10% ethanol (v/v) and 90% water (v/v), at a concentration of 7.1568 x 10 -2 molar. The test samples of ephedrine hemihydrate that were injected into HPLC instrument were mainly in a solvent that consisted of 90% (v/v) water and 10% ethanol (v/v). The solvent utilized for column of the HPLC instrument was 5% ethanol, 1% glacial acetic acid (v/v), and 94% water (v/v). The limit of detection (LOD) was found to be 2.9833 x 10 -5 molar and the limit of quantitation (LOQ) was found to be 8.9500 x 10 -5 molar. A standard curve presented showed a coefficient of determination of R 2 = 0.9857, which indicates that the model describes 98.57% variance in the dependent variable (peak area) that is predictable from the independent variable (molar concentration). The Pearson r correlation coefficient of this standard curve is 0.9928, indicating very high positive correlation. Ephedrine hemihydrate is assayed from matrixes that are utilized in the administration of this drug, including water and cellulose for tablet formulation. The determination of the drug ephedrine alkaloid is consistent and accurate utilizing isocratic conditions with HPLC.
Automated Construction of Road Networks from GPS Tracks

--This paper describes a framework for automating road networks using GPS (Global Positioning Systems) track measurements. Through observation and experiments on the data, it is decided that automating road networks is done in a two-step process. The first step is to identify intersections of roads, following an intersection model that also identifies and holds tracking groups leading to the first legs of incident roads. The second step, road segments incident to intersection nodes will be iteratively discovered by moving probe lines perpendicular to the heading directions of the generated roads. Initial intersections are assessed through analysing turns of vehicle trajectories and characteristics pertinent to where roads meet. Statistical techniques are used on tracks in relation to probe lines to exclude outliers and to locate median positions as vertices of roads. The method described in this paper exploits topological and geometric measures about neighbourhood of roads and applies machine learning techniques that iteratively compute optimized results for these measures.

Composite structure of vortices in two-component Bose-Einstein condensate

Abstract In contrast to one-component Bose-Einstein condensate case, the vortices in two-component condensate can have various complicated structures. The vortices in a space-homogeneous Bose-Einstein condensate have been studied in this paper. It is shown that the vortex structure is described by three dimensionless parameters. This is totally different from the usual one-component condensate case,where an isolated vortex is described by a parameterless dimensionless equation. The two-component vortex structure strongly depends on the sign of “interaction” constant of the components. A few types of vortices with different qualitative structure are explored. We show that the “super-density vortices” can exist, when the “interaction” constant is positive. The “super-density vortices” have the near-axis density greater than the equilibrium density of a homogeneous space Bose-Einstein condensate. We also show that the vortices with opposite direction of the condensate component rotation near the axis and far off the axis can exist.
Phenolic compounds and antioxidant activity of edible flowers

Introduction: Edible flowers has been used for thousands of years. They increase aesthetic appearance of food, but more often they are mentioned in connection with biologically active substances. The main ingredient of the flowers is water, which accounts for more than 80%. In small amounts, there are also proteins, fat, carbohydrates, fiber and minerals. Bioactive substances such as carotenoids and phenolic compounds determine the functional properties of edible flowers. Aim: The aim of this work was to characterize the phenolic compounds found in edible flowers and compare their antioxidant activity. Results: This review summarizes current knowledge about the usage of edible flowers for human nutrition. The work describes the antioxidant activity and phenolic compounds of some edible flowers. Based on literature data there is a significant difference both in content of phenolic compounds and antioxidant activity between edible flowers. These difference reaches up to 3075-fold in case of antioxidant potential. Among described edible flowers the most distinguishable are roses, peonies, osmanthus fragans and sambuco nero. Conclusions: Edible flowers are the new source of nutraceuticals due to nutritional and antioxidant values.
