Cross recurrence plot based synchronization of time series

Cross recurrence plot based synchronization of time series

The cross recurrence plot (CRP) can contain information about the synchronization of data series. This is revealed by the distorted main diagonal which is called line of syn- chronization (LOS). After isolating this LOS from the CRP one obtains a non-parametric rescaling function. With this function one can synchronize the time series. The underly- ing more-dimensional phase space allows us to include more than one parameter in this synchronization method as it usu- ally appears in geological applications, e.g. core synchro- nization. The comparison of CRP adjusted geophysical core data with conventional visual matching shows an acceptable reliability level of the new method which can be further im- proved by a better method for estimating the LOS. The ad- vantage is the automatic, objective and multivariate adjust- ment. Finally, this method of CRPs can open a wide range of applications as scale adjustment, phase synchronization and pattern recognition, for instance in geology, molecular biol- ogy and ecology.

Spatial time frequency distribution of cross term based direction of arrival estimation for weak non stationary signal

Spatial time frequency distribution of cross term based direction of arrival estimation for weak non stationary signal

cross terms of Wigner-Ville ambiguity function in [24]. The Wigner distribution achieves artifacts well known as cross terms that are contemplated and undesirable in some situations; nevertheless, it can be utilized to as- certain the existence of greatly little signal source terms, in this case, VLPs terms [25]. Using the ambigu- ity domain interpretation, Jeong and Williams explored the theory of the cross terms (or interferences) in spec- trograms [26]. A blind source separation technology applying both cross terms and auto-terms in the time- frequency distributions of the source signals was con- sidered by Belouchrani et al. in [27]. As an application, Fadaili et al. showed that the source separation can be accomplished via exploiting one of these algorithms to a set of spatial quadratic time-frequency distribution matrices corresponding merely to the named cross terms and/or to the named auto-terms [28]. When the cross term is considered from different perspectives, the cross term accurately reflects the relationship be- tween multiple signal components [29]. When the en- ergy difference between non-stationary signals is large, specifically in the situation of low signal-to-noise ratio, a weak non-stationary signal may be buried in the noise. At this point, the weak non-stationary signal is the desired signal. It is difficult or almost impossible to extract the auto-term of the weak non-stationary signal. The cross-term amplitude of strong and weak non- stationary signal did not decrease significantly. In gen- eral, the cross terms contain sufficient information of weak non-stationary signal for its DOA estimation. Therefore, in the case that both strong and weak non- stationary signals existing simultaneously, the cross terms of STFDs are used to obtain DOA of the desired weak non-stationary signal in this paper.

Velocity measurement simulative study of 
		twin plane ECT using advanced cross correlation technique

Velocity measurement simulative study of twin plane ECT using advanced cross correlation technique

Flow velocity is a critical information to have in order to ensure an optimum flow condition in a process plant. The combination of Electrical Capacitance Tomography and cross correlation technique has been successfully used to measure the velocity of multiphase flows. The peak of the cross correlated signals corresponds to the time taken by particles to move along the flow, thus its velocity can be derived. This paper investigates the capability of implementing an improved method of determining flow velocity by using a combined function of the cross correlation (CCF) and average squared differential (ASDF) functions in order to improve the accuracy of the velocity measurement. A velocity measurement simulation of a liquid/gas flow using MATLAB is employed and a comparison between the use of CCF and the combination of CCF/ASDF is made. The correlogram of the combined CCF/ASDF method has a sharper peak compared to the correlogram of the conventional CCF method, indicating that the peak of the function can be determined more accurately as the sharper peak can decrease the measurement uncertainty.

<p>Cross-Sectional Study on the Coping Strategies Among Glaucoma Patients Attending a Secondary Eye Clinic in Calabar, Nigeria</p>

<p>Cross-Sectional Study on the Coping Strategies Among Glaucoma Patients Attending a Secondary Eye Clinic in Calabar, Nigeria</p>

At the time of this research, no published study was found in Nigeria where glaucoma is a major cause of visual impairment and blindness, 14 or in any other part of Africa to have assessed the coping strategies in patients with glaucoma. Since patient perceptions of disease and methods of coping are heavily in fl uenced by culture and ethnicity, 9 it would be dif fi cult to generalise results from studies on coping in other regions. It is therefore important that a study on the coping methods of glaucoma patients be conducted in this part of the world. It is against this background that this study was conducted to examine the coping strategies of glaucoma patients at a secondary eye care facility in Calabar, Nigeria with a view to obtaining evidence-based information that could be used to provide psychosocial support to glaucoma patients in the setting.

<p>The Effect Of Social Media On The Choice Of Dental Patients: A Cross-Sectional Study In The City Of Jeddah, Saudi Arabia</p>

The quality of the web site is one of the important factors that in fl uences patients and visitors and has a good impact on the dental practice. It helps to improve custo- mers ’ respect for the professionalism of the clinic. 24 Reliance on a web site to organize patients ’ appointments also helps to save time and manage the of fi ce well. There is even a link between the design of the clinic ’ s website and the improvement of the patient ’ s perception of it. 16 Before-and-after images was also a major factor, espe- cially among females. In fact, most of dental advertise- ments relied on before-and-after photos, because they give an overall esthetic and quality results that patients desire. 25 This research was conducted in one place. As a result, there was no diversity of social classes. Nevertheless, it included middle class people. In spite of that, data from all participants were collected through an interview, making participants ’ answers more accurate. In addition, we have social media users only, it will be more interesting to compare between social medial users versus not. We sug- gest that the next research include various types of social classes and measure the different specialties of dentistry and the extent of people ’ s interest to search for them.

them had a relatively small sample size. Most importantly, as no study used a blinded randomized controlled trial design, results could have also different explanations because of the study design(s). Moreover, type and dosage of cross- sex hormonal treatment were often not reported, and when reported, there was poor consistency across studies. The same weakness applied to hormone therapy duration. While dif- ferences between analyzed groups were generally taken into account, more than half the studies did not mention/control for psychiatric comorbidity, which could have represented a critical bias in this kind of investigation. Finally, while studies were generally strict on the defined study population (formal diagnosis according to DSM criteria used at the time

The effect of the carbodiimide cross-linker on the structural and biocompatibility properties of collagen-chondroitin sulfate electrospun mat

The effect of the carbodiimide cross-linker on the structural and biocompatibility properties of collagen-chondroitin sulfate electrospun mat

In vitro degradation stability of the non-cross-linked and cross-linked mats was evaluated in the presence of the colla- genase for all electrospun CO and CO–CS mats. Enzymatic degradation has been studied by monitoring the weight loss of samples after 4, 24, and 72 h of incubation. Non-cross-linked mats have shown .95% loss in mass after 4 h of in vitro degradation in the collagenase (Figure 5). Degradation in non-cross-linked samples was characterized by a complete loss of weight. Cross-linking can increase scaffolds stability against the enzymatic degradation. This is due to the forma- tion of a cross-link between the cross-linker and surface functional groups of scaffolds because of a dense network. The non-cross-linked samples exhibited a greater extent of enzyme degradation at each time point compared to those that were cross-linked. In addition, within a 72 h interval, non- cross-linked samples were completely solubilized in enzyme solutions, while cross-linked samples were intact, especially those cross-linked mats containing CS. It is well-known that incorporation of GAG into CO indicates a significant increase of collagenase degradation resistance. 49 Exposure of cross-

Using the power balance model to simulate cross-country skiing on varying terrain

Using the power balance model to simulate cross-country skiing on varying terrain

for each straight line. As input to the power balance model, air drag and friction were estimated from the literature. Research assistants measured time by synchronized stopwatches when the skier passed the defined points along the track. An inverse relationship exists between time and distance, so that time measured as a function of distance can be used in a model where distance is a function of time. We did not perform any repeated measures of performance for this skier, which might be regarded a weakness of the current design. However, ski results from national and international sprint competitions, as well as performance tests in our laboratory indicate that elite skiers, like the skier in our study, are able to reproduce performance by a standard deviation of less than 2%.

Time and Frequency Domain Feature Extraction Method of Doppler Radar for Hand Gesture Based Human to Machine Interface

Time and Frequency Domain Feature Extraction Method of Doppler Radar for Hand Gesture Based Human to Machine Interface

Research in the development of Doppler radar as a motion detection has been conducted [20, 21]. An experiment and development of a 2.4 GHz Doppler radar system for detecting small-range motion was performed to overcome the resolution problem in PIR and ultrasonic sensor [20]. In this experiment, a Doppler radar was used to detect a human respiration signature by observing the radar output in time domain. Phase data processing is commonly used in improving the resolution in motion detection. Several methods of handling a distortion that may occur in phase processing has also been studied [21]. Considering motion detection/interpretation purposes, this method potentially provides smaller data, and its operation is independent of light availability. Several previous researches on hand gesture recognition using a radar system were developed based on CW, Frequency Modulated Continuous Wave (FMCW), and Ulta-wideband (UWB) radar. The extended Differentiate and Cross Multiply (DACM) algorithm to solve the null point and codomain restriction issued from traditional Doppler radar sensors [22], which is hand gesture recognition using FMCW millimetre wave, was reported [23]. The complex processing of the radar signal for obtaining the accurate detection result was needed. For example, a neural network was applied to recognize the pattern of radar output from a hand gestures target [24]. Feature extraction method can be used to reduce the complexity of recognition or classification process. With respect to the need of a compact and simple HMI, the Doppler response feature extraction method from CW radar output is proposed in this paper.

The impact of interdependent cross-age peer tutoring on social and mathematics self- concepts

The impact of interdependent cross-age peer tutoring on social and mathematics self- concepts

There are strong theoretical and empirical claims that cross-age peer tutoring improves process of learning elements related to social and academic attitudes. These claims have emerged from various theories such as: Role Theory (Sarbin, 1976), Social Constructivism (Topping & Ehly 1998) and the broader framework of Social Interdependence Theory (Johnson, D.W., & Johnson, R., T, 1987; 1989; Roseth, Johnson, D,W., & Johnson, R.T., 2008). With social interdependence perspectives incorporating elements from both Role Theory and Social Constructivism, while emphasising positive interdependence with the purpose of enhancing process of learning elements, such as cooperation within a group.

Analysis of the Effect of Work Shift and Time of Holidays on Employee Weak Levels

Analysis of the Effect of Work Shift and Time of Holidays on Employee Weak Levels

losses from various aspects starting from the performance of employees who will experience a decline, delay in the process of engine maintenance. Then from health which will also decrease if in the long term it will have a negative impact, the risk of various diseases will come. To avoid various types of losses, it is necessary to implement shift based work, by dividing 14 employees into 2 shifts, normal working hours or the first 8 hours of shift 1 with 10 employees, then the remaining working hours until production are categorized as shift 2 with 4 employees, so that each employee has their own shift schedule. And the level of employee fatigue can be reduced, their performance can be returned optimally, of course, this can increase production capacity by running production without obstacles, based on the explanation described above, an experimental design will be carried out based on work shift and holiday time to see the effect on maintenance staff fatigue . The objectives to be achieved are to find out the influence of work shifts and time off on the level of fatigue of maintenance employees before and after changes in work shifts.

Influence of Food Composition on Freezing Time

Influence of Food Composition on Freezing Time

Like most food preservation methods, the freezing process for food has evolved over a significant period of time. As an extension of cooling, the primary goal of food freezing has been the reduction of microbial growth and/or control of reactions causing spoilage of the food, as well as the corresponding extension of product shelf-life. In addition, the process has extended the availability of many food commodities for consump- tion at any time during the year. Frozen food can be transported for longer distances and the process has contributed to making foods avail- able on a worldwide basis. For most applications, the food products are held in storage for some period of time before thaned, and prepared for consumption. More recently, the process has evolved to include a varie- ty of products that are consumed in a frozen state [1]. The principal objective of the new general and specific hygiene rules is to ensure a high level of consumer protection with regard to food safety. Food busi- ness operators shall ensure that all stages of production, processing and distribution of food under their control, satisfy the relevant hygiene requirements, laid down in Regulation (EC) No. 852/2004. This regula- tion emphasizes the importance of cold chain throughout HACCP (Haz- ard Analysis and Critical Control Point) system for all foodstuff that re- quire cooling or freezing regime [2]. Kassianenko and co-workers [3] emphasis the importance of cold chain, which is a vital part of modern global trade as it has impact on all food commodities. In today’s mod- ern society, refrigerated storage is one of the most widely practiced methods of preserving perishable food. Improper use of this process in- creases the potential risk and microbial hazards will advance, thus lead- ing to the food borne illnesses.
