Apparatus and associated method for effectuating post-FFT correction of fine frequency offset

In orthogonal frequency-division multiplexing (OFDM) system (100), the receiver of the OFDM signal defined by the air interface to training symbols contained in the frame structure of the air interface (110) and can efficiently estimate a fractional frequency offset (e.g. frequency offset) is smaller than a spacing between the carrier receiving FFT algorithm (106). The algorithm can be modified as to estimate a large frequency offset (e.g., greater than a carrier frequency offset between the spacing) (126 and 128) by increasing hardware complexity. In the simplest embodiment, the algorithm does not require a correlator block. Frequency detection itself in very low SNR environment did very well. However, if noise plus timing error is present, system parameters may be designed to substantially ensure good performance in low SNR environments.
LBCH: Load Balancing Cluster Head Protocol for Wireless Sensor Networks

In recent years, Wireless Sensor Networks (WSNs) received great attention because of their important applications in many areas. Consequently, a need for improving their performance and efficiency, especially in energy awareness, is of a great interest. Therefore, in this paper, we proposed a lifetime improvement fixed clustering energy awareness routing protocol for WSNs named Load Balancing Cluster Head (LBCH) protocol. LBCH mainly aims at reducing the energy consumption in the network and balancing the workload over all nodes within the network. A novel method for selecting initial cluster heads (CHs) is proposed. In addition, the network nodes are evenly distributed into clusters to build balanced size clusters. Finally, a novel scheme is proposed to circulate the role of CHs depending on the energy and location information of each node in each cluster. Multihop technique is used to minimize the communication distance between CHs and the base station (BS) thus saving nodes energy. In order to evaluate the performance of LBCH, a thorough simulation has been conducted and the results are compared with other related protocols (i.e. ACBEC-WSNs-CD, Adaptive LEACH-F, LEACH-F, and RRCH). The simulations showed that LBCH overcomes other related protocols for both continuous data and event-based data models at different network densities. LBCH achieved an average improvement in the range of 2–172%, 18– 145.5%, 10.18–62%, 63–82.5% over the compared protocols in terms of number of alive nodes, first node died (FND), network throughput, and load balancing, respectively.
Factors Affecting Health Related Quality of Life among Women with Breast Cancer Receiving Chemotherapy

Introduction: Chemotherapy is the most common therapeutic modality used in the treatment of breast cancer. It has different side effects, with associated degrees of disruption in quality of life. Health-related quality of life (HRQOL) is a multidimensional concept, considered as a subjective assessment of physical, social, psychological, and spiritual factors. The study aim: To assess factors affecting health related quality of life among women with breast cancer receiving chemotherapy. Design: Quantitative, descriptive correlational design was used. Setting: Chemotherapy Department, King Abdullah Medical City (KAMC) in Makkah. Sample: A convenient sample of 122 women was selected. Tools: Three tools were used for data collection. First, demographic and clinical data. Second, 36-Short Form version 1, and third, Factors affecting health related quality of life among women with breast cancer receiving chemotherapy questionnaire. Results: More than half 51.6% of the studied women were moderately affected regarding overall factors affecting health related quality of life. There was a significant negative relationship between psychological factors and quality of life (P < 0.001). Conclusion: The majority of studied women had moderately affected by overall social factors and nearly two third had moderately affected by overall psychological factors. While more than half were moderately affected by overall physical and spiritual factors. Moreover, women had moderate level of overall QOL. Recommendation: The study recommended for further research to develop self-care practices educational program for women with breast cancer receiving chemotherapy.
Associated Factors of Chronic Kidney Disease among Hyponatraemic Elderly Patients Attending a Primary Care Clinic

Article history Received 20 Nov 2018 Accepted 10 Dec 2018 Introduction: Chronic kidney disease (CKD) emerges to be an important geriatric health issue. It may progress to end stage renal failure and affect the quality of life. However, little is known about the associated factors of CKD. So this study aimed to determine the associated factors of CKD among hyponatraemic elderly. Methods: This is a retrospective study of hyponatraemic patients aged ≥ 60 years attending outpatient clinic in 2014. Blood test results of glucose, potassium, creatinine, medical history, blood pressure, medication and demographic data were captured from patient records. Each patient’s estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI Creatinine Equation. CKD is defined as eGFR of < 60 ml/min/1.73m. SPSS 21 was used to do the analysis. Results: Totally 257 patients with mean age of 72.9 ± 7.3 years were enrolled in this study. Of them 73 (28.4 %) elderly had CKD. The mean eGFR was 72.62 ± 24.14 ml/min/1.73m, mean BP was (135.75 ± 18/10) mmHg. Of the participants, 134 (52.1 %) were men, 151 (58.8 %) were diabetics, 247 (96.1 %) had hypertension. The independent associated factors of CKD were increasing age (OR 1.08; 95 % CI 1.03-1.13; p = 0.002), hyperglycaemia (OR 1.10; 95 % CI 1.02-1.18; p = 0.017) and the use of loop diuretics (OR 5.15; 95 % CI 1.5217.38; p = 0.008). Conclusion: Hyperglycaemia and loop diuretics usage are found to be significantly associated with CKD among elderly patients attending a primary care clinic. Hence every effort should be made to optimise glucose control and cautious in the usage of loop diuretics to retard the decline in renal function.
Extraction of Musical Motifs from Handwritten Music Score Images

A musical motif represents a sequence of musical notes that can determine the identity of a composer or a music style. Musical motifs extraction is of great interest to musicologists to make critical studies of music scores. Musical motifs extraction can be solved by using a string mining algorithm when music data is represented as a sequence. When music data is initially produced in XML or MIDI format or can be converted into those standards, it can be automatically represented as a sequence of notes. So, in this work, starting from digitized images of music scores, our objective is twofold: first, we design a system able to generate musical sequences from handwritten music scores. To address this issue, one of the segmentation-free R-CNN models trained on musical data have been used to detect and recognize musical primitives that are next transcribed into XML sequences. Then, the sequences are processed by a computational model of musical motifs extraction algorithm called CSMA (Constrained String Mining Algorithm). The consistency and performances of the framework are then discussed according to the efficiency of the R-CNN ( Region-proposal Convolutional Neural Network) based recognition system through the estimation of misclassified primitives relating to the detailed account of detected motifs. The carried-out experiments of our complete pipeline show that it is consistent to find more than 70% of motifs with less than 20% of average detection/classification R-CNN errors
Voyage au cœur des EDSRs du second ordre et autres problèmes contemporains de mathématiques financières

Cette these presente deux principaux sujets de recherche independants, le dernier etant decline sous la forme de deux problemes distincts. Dans toute la premiere partie de la these, nous nous interessons a la notion d’equations differentielles stochastiques retrogrades du second ordre (dans la suite 2EDSR), introduite tout d’abord par Cheridito, Soner, Touzi et Victoir [25] puis reformulee recemment par Soner, Touzi et Zhang [107]. Nous prouvons dans un premier temps une extension de leurs resultats d’existence et d’unicite lorsque le generateur considere est seulement continu et a croissance lineaire. Puis, nous poursuivons notre etude par une nouvelle extension au cas d’un generateur quadratique. Ces resultats theoriques nous permettent alors de resoudre un probleme de maximisation d’utilite pour un investisseur dans un marche incomplet, a la fois car des contraintes sont imposees sur ses strategies d’investissement, et aussi parce que la volatilite du marche est supposee etre inconnue. Nous prouvons dans notre cadre l’existence de strategies optimales, caracterisons la fonction valeur du probleme grâce a une EDSR du second ordre et resolvons explicitement certains exemples qui nous permettent de mettre en exergue les modifications induites par l’ajout de l’incertitude de volatilite par rapport au cadre habituel. Nous terminons cette premiere partie en introduisant la notion d’EDSR du second ordre avec reflexion sur un obstacle. Nous prouvons l’existence et l’unicite des solutions de telles equations, et fournissons une application possible au probleme de courverture d’options Americaines dans un marche a volatilite incertaine. Le premier chapitre de la seconde partie de cette these traite d’un probleme de pricing d’options dans un modele ou la liquidite du marche est prise en compte. Nous fournissons des developpements asymptotiques de ces prix au voisinage de liquidite infinie et mettons en lumiere un phenomene de transition de phase dependant de la regularite du payoff des options considerees. Quelques resultats numeriques sont egalement proposes. Enfin, nous terminons cette these par l’etude d’un probleme Principal/Agent dans un cadre d’alea moral. Une banque (qui joue le role de l’agent) possedant un certain nombre de prets, souhaite echanger leurs interets contre des flux de capitaux. La banque peut influencer les probabilites de defaut de ces emprunts en exercant ou non une activite de surveillance couteuse. Ces choix de la banque ne sont connus que d’elle seule. Des investisseurs (qui jouent le role de principal) souhaitent mettre en place des contrats qui maximisent leur utilite tout en incitant implicitement la banque a exercer une activite de surveillance constante. Nous resolvons ce probleme de controle optimal explicitement, decrivons le contrat optimal associe ainsi que ses implications economiques et fournissons quelques simulations numeriques.
Developing Two Different Novel Techniques for Arabic Text Stemming

Stemming is used to produce stem or root of words. The process is vital to different research fields such as text mining, sentiment analysis, and text categorization, etc. Several techniques have been proposed to stemming Arabic text and among them, Khoja and light-10 stemmers are the most widely used. In this paper, we propose and evaluate two different stemming techniques to Arabic that are based on light stemming techniques. The new stemmers are compared to best reported light stemmer, which is light-10. Results and experiments, which were conducted using standard collections, reveal that The proposed stemmers yield 5.13% and 13.1% improvement in retrieval performance over light 10 with 0.369 average precision and 0.397, respectively and the improvement is statistically significant.
Partial Greedy Algorithm to Extract a Minimum Phonetically-and-Prosodically Rich Sentence Set

A phonetically-and-prosodically rich sentence set is so important in collecting a read-speech corpus for developing phoneme-based speech recognition. The sentence set is usually searched from a huge text corpus of million sentences using the optimization methods. One of the commonly used optimization methods for this case is a Least-to-Most Greedy (LTMG) algo-rithm. It is effective in minimizing the number of phoneme-units. Unfortunately, it does not distribute their frequencies. In this paper, a new method called Partial LTMG algorithm (PLTMG) is proposed to search an optimum set containing triphones and prosodies those are distributed in a near-uniform fashion. Testing on an Indonesian text corpus of ten million sentences crawled from some websites of newspapers and novels shows that the proposed method is not only capable of minimizing both phoneme-units and prosodies but also effective in distributing their frequencies.
Comparison of QoS guarantee techniques for VoIP over IEEE802.11 wireless LAN

An emerging killer application for enterprise wireless LANs (WLANs) is voice over IP (VoIP) telephony, which promises to greatly improve the reachability and mobility of enterprise telephony service at low cost. None of the commercial IEEE 802.11 WLAN-based VoIP products can support more than ten G.729-quality voice conversations over a single IEEE 802.11b channel on real-world WLANs, even though the physical transmission rate is more than two orders of magnitude higher than an individual VoIP connection's bandwidth requirement. There are two main reasons why these VoIP systems' effective throughput is significantly lower than expected: VoIP's stringent latency requirement and substantial per-WLAN-packet overhead. Time-Division Multiple Access (TDMA) is a well-known technique that provides per-connection QoS guarantee as well as improves the radio channel utilization efficiency. This paper compares the effective throughput of IEEE 802.11, IEEE 802.11e and a software-based TDMA (STDMA) protocol that is specifically designed to support WLAN-based VoIP applications, on the same commodity IEEE 802.11 WLAN hardware. Empirical measurements from a VOIP over WLAN testbed show that the numbers of G.729-quality voice conversations that IEEE 802.11, IEEE 802.11e and STDMA can support over a single IEEE 802.11b channel are 18, 22 and 50, respectively.
The fiscal policy impact to the Greek economy: Asymmetric evidence from a switching regime approach

Abstract. This paper empirically investigates the magnitude of general government expenditures and tax income revenues to the Greek output within a regime-switching framework during the period 2000:1 – 2016:3. This nonlinear methodology captures the fiscal effects across periods of high and low growth. In more deep analysis, we examine the relationship of expenditures and GDP over time, by adopting the GARCH(1,1)-DCC methodology. Our results show that the magnitude of general government expenditures is larger during periods of low growth or economic recession, as well as the magnitude of tax income revenues. Furthermore, during the “bailout” period (2010-2016) when the fiscal adjustment was strict, GDP seem to be even stronger negatively affected by the reduction of government expenditures. Keywords. Fiscal policy impact, regime switching, GARCH-DCC, Greek economy. JEL. E61, E62, H21.
MEANING AND FORM IN NURSERY RHYMES TRANSLATION

MAKNA DAN BENTUK DALAM PENERJEMAHAN LAGU-LAGU ANAK AbstractTranslating nursery rhymes is not an easy task. The problems of equivalence in meaning and form as well as in the harmony between the translated lyrics and the music are aspects that need to be considered by the translators. By considering nursery rhyme lyric as poetry text, this research analyzes the equivalence of meaning and form in nursery rhymes translation. This research focuses on five nursery rhymes. The meaning analysis was done by conducting particular procedures on translation quality assessment. Meanwhile, the analysis of the form was conducted by comparing the two versions of the nursery rhymes focusing on the sound values. From the equivalence of meaning, the result shows that most nursery rhymes are translated less accurately. On the other hand, the finding of the equivalence in form shows that most of the auditory devices are deleted while most of the rhymes are shifted. This research is expected to give a contribution to song translation activities especially those involving children as the target listeners. Keywords: equivalence, accuracy, sound values, auditory devices, rhymes AbstrakMenerjemahkan lagu anak bukanlah hal yang mudah. Masalah kesepadanan makna dan bentuk, serta harmonisasi antara lirik terjemahan dan musik adalah aspek-aspek yang harus dipertimbangkan oleh penerjemah. Dengan mempertimbangkan lirik lagu anak sebagai teks puisi, penelitian ini menganalisis kesepadanan antara makna dan bentuk dalam terjemahan lagu anak. Dengan menggunakan teknik sampling, penelitian ini berfokus kepada lima lagu anak. Analisis makna dilakukan dengan prosedur penelitian kualitas terjemahan sedangkan analisis bentuk dilakukan dengan membandingkan dua versi lagu anak dengan fokus kepada sound values (bunyi). Analisis kesepadanan makna menunjukkan bahwa sebagian besar lagu anak diterjemahkan dengan kurang akurat. Dari segi bentuk, sebagian besar auditory devices dihapus sedangkan sebagian besar rima bergeser. Penelitian ini diharapkan dapat memberikan kontribusi terhadap penerjemahan lagu khususnya yang melibatkan anak-anak sebagai pendengar sasaran.
the Impact of the Market Cycle on the Value Relevance of book Values and Earnings in the banking Industry : an Evidence from Poland

The paper aims at the empirical investigation of the impact of the market cycle on the value relevance of book values and earnings in the banking industry. unlike most prior studies, the paper directly examines the influence of cyclical fluctuations in investors’ sentiments on the informativeness of these key accounting variables. Moreover, the study enhances the literature on the value relevance of banks’ financial reporting by providing an empirical evidence from the emerging capital market of Poland. The examined sample covers all domestically-based commercial banks listed on the Warsaw Stock Exchange over the period 1997–2016. The empirical evidence based on the analyses of parametric and non-parametric correlation and regression indicates a significant impact of the market cycle on the value relevance of book values which markedly increases (decreases) in the periods of bull (bear) market. In contrast, the informativeness of earnings seems to be driven primarily by factors other than investors’ sentiments. The results of the research indicate that the course of the market cycle is partially driving the fluctuations of the value relevance of book values of equity and net earnings in the Polish banking industry. There is a need for further investigation of the impact of market cycles on the value relevance of accounting data, not only in the context of the banking sector.
Outcomes reported in randomised clinical trials of major depressive disorder treatments in adolescents: a systematic scoping review protocol

Introduction Major depressive disorder (MDD) is a common mental health condition in adolescents. Randomised clinical trials (RCTs) are the gold standard for assessing the safety and efficacy of interventions in this population. Heterogeneity in the outcomes measured and reported between RCTs limits the ability to compare, contrast, and combine trial results in a clinically meaningful way. There is currently no core outcome set (COS) available for use in RCTs evaluating interventions in adolescents with MDD. We will conduct a systematic scoping review of outcomes reported in adolescent depression RCTs to assess the variability of trial outcomes and to inform the development of a COS for adolescent MDD. Methods and analysis We will apply methods based on the Joanna Briggs Institute scoping review methods manual. RCTs evaluating any treatment intervention for adolescent MDD published in the last 10 years will be located using an electronic bibliographic database search (MEDLINE, PsycINFO and Cochrane Central Register of Controlled Trials). Title and abstract screening, full-text screening, and data charting of eligible studies will be performed in duplicate. Outcomes identified will be mapped to an outcome-domain framework. Data analysis will include summary statistics of the characteristics of the included trials and outcomes. Ethics and dissemination The results of this review will inform the development of a COS for adolescent MDD. The development and implementation of a COS for RCTs evaluating interventions in adolescents with MDD promise to help reduce variability in trial outcome selection, definition, measurement and reporting, ultimately facilitating evidence synthesis that will help to identify the best treatment practices for adolescents with MDD.
Socioeconomic status and pulmonary function, transition from childhood to adulthood: cross-sectional results from the polish part of the HAPIEE study

Objective Previous studies have reported inverse associations between socioeconomic status (SES) and lung function, but less is known about whether pulmonary function is affected by SES changes. We aimed to describe the relationship of changes of SES between childhood and adulthood with pulmonary function. Design Cross-sectional study. Participants The study sample included 4104 men and women, aged 45–69 years, residents of Krakow, participating in the Polish part of the Health, Alcohol and Psychosocial Factors in Eastern Europe Project. Main outcome Forced expiratory volume (FEV1) and forced vital capacity (FVC) were assessed by the standardised spirometry procedure. Participants were classified into three categories of SES (low, moderate or high) based on information on parent’s education, housing standard during childhood, own education, employment status, household amenities and financial status. Results The adjusted difference in mean FVC between persons with low and high adulthood SES was 100 mL (p=0.005) in men and 100 mL (p<0.001) in women; the differences in mean FEV1 were 103 mL (p<0.001) and 80 mL (p<0.001), respectively. Upward social mobility and moderate or high SES at both childhood and adulthood were related to significantly higher FEV1 and FVC compared with low SES at both childhood and adulthood or downward social mobility. Conclusions Low SES over a life course was associated with the lowest lung function. Downward social mobility was associated with a poorer pulmonary function, while upward mobility or life course and moderate or high SES were associated with a better pulmonary function.
