Handoff dwell time distribution effect on mobile network performance

In this paper, the sensitivity of the handoff dwell time (HDT) model on wireless mobile network performance is studied. We present an approach on the basis of the universal approximation property of phase-type (PH) distribution in order to address the intractable numerical issue caused by HDT. We first obtain the steady state probability under the general HDT. The performance metrics from the perspective of base station (BS) as well as from the point view of call are developed. The PH-type HDT is then assumed to derive the numerically tractable expressions for the performance metrics. Finally, the truncated Gaussian HDT is approximately fitted by the PH distribution via expectation maximization algorithm to reuse the closed form analytical expression. The comparison shows that, in terms of the BS performance, the handoff blocking probability exhibits a significant discrepancy whenever one uses the exponential or truncated Gaussian HDT distribution, while the new call blocking probability is less sensitive to different HDT. In addition, HDT has little impact on the call performance with respect to the call completion probability and total waiting time. Both the analytical model and the approximation approach are verified by simulation.

Detection of Taylorella asinigenitalis in donkey jacks in Italy

Taylorella equigenitalis -like organisms isolated from donkeys and horses ([Katz and others 2000][1], [Jang and others 2001][2]) in the USA in 1997/1998 were later classified as Taylorella asinigenitalis on the basis of taxonomic studies ([Jang and others 2001][2]). T asinigenitalis was
Short-Term Measurements of Household Electricity Demand During Hot Weather in Kuala Lumpur

The aim of this study was to conduct short-term measurements on household electricity demand under hot weather conditions in a residential area in Kuala Lumpur. The measurements included total and air conditioner (AC) electricity consumption of 10 households in an apartment building as well as outdoor air temperatures, which were collected from March to May 2016. Results indicated that the average AC electricity consumption contributed to a major portion of total household electricity consumption, which ranged from 19.4 to 52.3% during the measurement period. Additionally, 1-minute interval time series data indicated household energy consumption more accurately than 30- or 60-minute interval.
Sensorless control of PMSM in a ultra high speed region taking iron loss into account

The importance of ultra high speed (≥ 50 krpm) motor technology has surfaced for various applications including turbo-compounding system, engines, and air blowers. However, there are challenging issues in a high speed motor technology: 1) robust mechanical structure, 2) materials like low loss silicon steel and high tensile strength, and 3) control issues such as the PWM delay, the PWM distortion, and the iron loss. Especially, the iron loss is usually neglected in the general permanent magnet synchronous motor (PMSM) control. Aside from the motor efficiency, the iron loss alters the PMSM dynamic model. Since the iron loss is not reflected in the conventional sensorless methods, the angle error grows steadily as the speed increases to an extremely high region. In this paper, a sensorless control method considering the iron loss is proposed. It cures the angle error in a high speed region, and the performances are demonstrated through simulation and experimental results.
Periodic Respiratory Pattern Occurring in Conjunction with Eye Movements during Sleep

With each flurry of rapid eye movements during the sleep of human subjects there is a decreased amplitude of respiration and a slight increase in rate. Occasionally the rhythmic breathing pattern may even resemble Cheyne-Stokes respiration. The consistency of this breathing pattern suggests that respiration in this stage of sleep is not a direct function of dream content.

The Influence of Culture Time and Passage Number on the Morphological and Physiological Development of Caco-2 Cells

Abstract The Caco-2 cell line is used by many investigators as a model of the intestinal epithelium to study nutrient uptake and transport. Our goal was to create an awareness of inherent variabilities in the Caco-2 cell line which may influence their suitability as a model or their application to specific problems. To study the influence of passage on the model, cultures were monitored from passage 20 to 109. Transepithelial electrical resistance (TEER) and sucrase activity (measured in 21-day-old cultures) increased through about passage 36. TEER values declined after about passage 60; sucrase remained elevated but variable. Cells at passage 22, 33, and 72 were grown simultaneously for 24 days. Older-passaged cells reached plateau phase sooner. Before Day 15, passage 72 cells had higher TEER and lower permeability to 14C-mannitol than passages 22 and 33; however, after Day 15 all passages showed similar permeability. On Day 21, passage 72 cells had significantly lower alkaline phosphatase activity than did the other passages. Electron microscopy did not reveal any major morphological differences between the passages; however, it did show that some areas of cells grown on membranes were not monolayers but were several cells thick with varied morphology. Investigation of the formation of these multilayered areas showed them to be an inherent part of cell growth under the conditions used. These results emphasize the inherent variability in Caco-2 cell models and emphasize the need to monitor closely the culture characteristics during growth and differentiation under specific experimental conditions.
Towards real time vision based UUV navigation using GPU technology

The last decade has witnessed the establishment of image processing as a viable means of aiding underwater navigation. However, many such systems are only implemented in pre-processing and offline due to their excessive computational demands. Real-time techniques often require special purpose hardware or impose limitations on the system to obtain real-time performance at the expense of accuracy. The rapidly improving performance of graphics hardware as well as the recent improvements in its programmability with developments such as NVIDIA's CUDA, has made graphics hardware a practical alternative to CPUs for highly parallel tasks such as image processing. This paper details the implementation of the scale invariant feature transform (SIFT) using a graphics processing unit (GPU) instead of a conventional CPU in order to achieve real-time performance of a vision based navigation system. The performance of both the GPU and CPU SIFT implementations are compared and evaluated using images gathered by the newly developed ROVLATIS off the west coast of Ireland.
Determinants of the financial stability of mutual health organizations: a study in the Thies region of Senegal.

The financial sustainability of community-based health insurance schemes has been debated in the literature given concerns that small risk pools voluntary membership and weak financial systems might jeopardize the schemes. The research reported here investigates the main factors influencing the financial stability of mutual health organizations (MHOs) in the Thies region of Senegal. The study covered the four-year period 2000-03 and comprised a household survey component a MHO survey component and a provider survey component encompassing all 27 schemes in the Thies region that have been fully functional for at least two years. Despite growth in the number of MHO members and beneficiaries during the four years scheme financial performance overall was poor. The primary factors explaining this poor performance were: problems of adverse selection low dues recovery unrecovered loans (particularly for expenditures at the hospital level) frequent changes to benefit packages without concurrent changes to premiums and limited use of financial tools. In order to promote MHO sustainability greater support is needed for the design of schemes and particularly for their management. Reinsurance which helps protect against random risk may have a role to play in the future but the immediate focus should be on stronger financial management. (authors)
Classification of motor imagery by means of cortical current density estimation and Von Neumann entropy

The goal of the present study is to employ the source imaging methods such as cortical current density estimation for the classification of left- and right-hand motor imagery tasks, which may be used for brain–computer interface (BCI) applications. The scalp recorded EEG was first preprocessed by surface Laplacian filtering, time-frequency filtering, noise normalization and independent component analysis. Then the cortical imaging technique was used to solve the EEG inverse problem. Cortical current density distributions of left and right trials were classified from each other by exploiting the concept of Von Neumann entropy. The proposed method was tested on three human subjects (180 trials each) and a maximum accuracy of 91.5% and an average accuracy of 88% were obtained. The present results confirm the hypothesis that source analysis methods may improve accuracy for classification of motor imagery tasks. The present promising results using source analysis for classification of motor imagery enhances our ability of performing source analysis from single trial EEG data recorded on the scalp, and may have applications to improved BCI systems.
The Evaluation of Restaurants Websites: American Pizza Restaurants Case Study

Many Authors highlighted the advantage of being affiliated in hospitality industry. This was challenged by the evolution of technology and new generations' characteristics. Today’s Internet afforded limitless opportunities for independent restaurants to stand against the affiliated ones. The wide spread of smartphones created an opportunity to reach customers anywhere and opened a channel of distribution for restaurants products targeting new generations, who were recognized as technology savvy customers. The research aimed to evaluate the restaurants’ websites in today’s business environment. This research used restaurant's website assessment tool and word cloud analysis technique. The authors developed a website checklist, which was customized for restaurants. The study started with sixty-seven restaurants (i.e., twenty-eight independent restaurants, thirty-nine chain restaurants) and ended with forty-seven restaurants (i.e., twelve independent restaurants, thirty-five chain restaurants) which were included in the research sample. The research findings highlighted several issues in restaurants’ websites’ performance and how far the affiliation supported restaurants’ websites compared with independent ones. A list of recommendations was developed to help restaurants’ owners in maximizing the impact of affiliation on their business and to develop their restaurants’ websites.
Sparse MAP equalizers for turbo equalizations

The turbo equalization scheme provides nearly optimal performance, but when it is employed in sparse multipath channel environments, the equalizer complexity can prohibit its use. In this paper, we develop a parallel trellis n-tap soft-input soft-output maximum a posteriori (MAP) equalizer which can consider n dominant taps of sparse channels with reasonable complexity. It is shown that turbo equalization employing the n-tap MAP equalizer can nearly achieve the asymptotic performance of the optimal maximum likelihood (ML) detector for the combined channel encoder and intersymbol interference (ISI) channel assuming perfect ISI cancellation. It is also shown that increasing n has favorable effects on the convergence of turbo equalizations employing n-tap MAP equalizer by EXIT chart analysis.
[Efficiency of a postoperative treatment after rotator cuff repair with a continuous passive motion device (CPM)].

AIM The main objective of this study was to prove that a postoperative combined continuous passive motion (CPM) and physiotherapy treatment protocol (CPM group) can achieve 90 degrees active abduction in the shoulder joint earlier than physiotherapy alone (PT group). The indication was a complete tear of the rotator cuff. METHOD The study was conducted under in-patient and out-patient conditions. 55 patients were included in this study. The prospective, randomized multicenter study design complies with DIN EN 540. The primary endpoint was the time span until 90 degrees active abduction was achieved by the patients. RESULTS Patients in the CPM group reached the primary endpoint on average 12 days earlier than the control group. This difference was statistically significant (p = 0.0292). Analyzing the secondary endpoints, e. g. , pain and disablement, the results in the CPM group showed again advantages of the combined treatment protocol (CPM + physiotherapy). CONCLUSION The postoperative treatment of a total tear of the rotator cuff with a combined continuous passive motion and physiotherapy protocol provided a significantly earlier range of motion in the shoulder joint than physiotherapy alone. There was no report of CPM-related adverse effects.
SEXUAL COMPATIBILITY IN MEDFLY (DIPTERA: TEPHRITIDAE) FROM DIFFERENT ORIGINS

Abstract The use of the Sterile Insect Technique to control and/or eradicate insect pest populations has been extensively applied to medfly. However, patented differences in sexual compatibility between populations or strains from different origins has been a serious concern to a wider use of sterile flies, and in particular sterile males of genetic sexing strains (GSS). In the present experiments, the sexual compatibility and mating performance of flies from 9 countries representing 5 continents and 4 GSS were measured. It is demonstrated that, from a qualitative standpoint, wild medfly populations world-wide have not yet evolved specific sexual behaviors indicative of incipient pre-mating isolation mechanisms under local natural selection. Wild medfly populations are as sexually compatible with GSS as they are with other wild populations. On that basis, the same mass reared strain can now be used worldwide, as long as it fulfills the standard quality control requirements.
Creating Sense Vectors using Cross-lingual Information

Word-sense disambiguation (WSD) is the process of identifying the meaning/sense of a word in a sentence. It is a common phenomenon for a word in English(or any other language) to have more than one meaning. In language processing the task of WSD is to distinguish between the different senses of the words appearing in different contexts. However, this task is daunting as WSD remains to be an open problem. The significance of the problem can be estimated by its relevance in field of Semantics, Search Query improvement, et cetera. To give an example of WSD problem consider the three sentences below.

EFEK PENGUMUMAN KEBIJAKAN DIVIDEN TERHADAP RETURN SAHAM YANG TERGOLONG JAKARTA ISLAMIC INDEXS

This research aims to test dividend signaling theory in the Jakarta Islamic Index groups. Signaling theory states that dividend policy has information content that can influence to share price. This research usesamples in the form of company allocating dividend for period 2006-2007 which listed on Jakarta Islamic Index. Final samples which are utilized in this research are equal to 12 firms observation. Using the event-study method, the result of our research shows that at the significant level of 5%, there is only one working days which yield the abnormal return that is significant at the dividend announcements. Those are the sixth day before the event date with the value of 0.00889 or around 0.9%. The final conclusion is that stock price will negatively reacted to the announcement of dividend. Overall, the evidence tends to support the dividend irrelevancy hypothesis, but does not provide a support for the signaling theory. Evidence also indicates that dividend payment does not signal any information to the investors, which needs to be further investigated.
The potential of conflicts of interest arising in the activities of credit rating agencies in Ukraine

This paper presents a comprehensive system of 38 indicators, which allows identification of possible endogenous sources and evaluation of the potential of conflicts of interest arising both at the corporate (in models of ownership, business and financial activities, corporate governance and organizational structures) and operational (ana-lyst) levels of credit rating agencies (CRAs). Testing of proposed system of indicators was carried out based on the content analysis of the public information on the activities of five authorized credit rating agencies of Ukraine.It is determined that at the beginning of 2017 the most sensitive to the risk of conflicts of interest were “Standard Rating” (74% of threat signals of the total number of indica- tors), “Expert Rating” (57%) and “Rurik” (37%). The highest potential of conflicts’ of interest escalation was identified in the models of financial activities (80% of threat signals of the total number of indicators of that group) and models of ownership of Ukrainian CRAs (63%). The estimations of the risk level are proposed to be regarded mainly as signals of the potentially high sensitivity of the particular CRA to the risk of conflicts’ of interest escalation.Such signals, in particular, can be used by the regulators for carrying out remote monitoring activities of CRAs, for adopting supervisory and regulatory decisions. In turn, managers and owners of rating agencies can conduct a more detailed analysis of the detected potential sources of conflict of interest with the aim of identification, localization, and elimination of shortcomings in the system of conflict of interest management. rating agencies may lead to a significant devaluation of the credit ratings’ quality due to rating shopping, manipulations and problems with disclosure. As a result, substantial adverse externalities could be generated. Among them – the possibility of destabilization and contagion of financial markets, distortions in the pricing of securities, deterioration in the financial conditions and bankruptcy of some companies and even states, etc. On the other hand, the devaluation of the quality of ratings leads to erosion of reputational capital of CRAs, reducing investors’ confi-dence in them as in information intermediaries and as a result – to a partial loss of clients and therefore – of income.
Company Characteristics, Dominant Personalities in Board Committees and Internet Financial Disclosures by Malaysian Listed Companies

This paper investigates whether the internet financial disclosure can be explained by a company’s characteristics and the dominant personalities in board committees of the Malaysian listed companies. Ten hypotheses were tested using data collected from 194 Malaysian listed companies’ websites. Specifically, this paper examines the relationship between the internet financial disclosures (IFD) and the variables, namely internationality, leverage, foreign shareholders, level of technology, firm age, number of shareholders, listing status, dominant personalities in the audit committee, and chairmen of audit and nomination committees. It is found that the level of technology, firm age, number of shareholders and listing status significantly affect the level of IFD. However, the dominant personalities in the audit and nomination committees affect negatively the level of IFD in Malaysia. The study provides some evidence to support the signaling theory and the cost and benefit hypothesis in relation to internet disclosure.
