Signal Power Estimation Via Vector and Matrix Approaches

Signal power estimation using an array of sensors is needed in many applications and can be done via both Vector Approaches (VA) and Matrix Approaches (MA). We consider a modified adaptive VA (MAVA) and a modified adaptive MA (MAMA) for signal power estimation and for achieving prescribed peak sidelobe levels as well as having some control over the main-beam shape. The formulations of both MAVA and MAMA are convex optimization problems, and thus globally optimal solutions can be determined efficiently. We will show that MAVA and MAMA are equivalent and that they are robust to small sample size problems, the presence of coherent interferences, and steering vector errors.
Study of prevalence of rheumatic heart disease and congenital heart disease among school children in central Nepal

To determine the prevalence of rheumatic heart disease (RHD) and congenital heart disease (CHD) among school children in Chitwan district using clinical and echocardiographic criteria. This is a crosssectional study involving 7650 school children from general schools (4100) and private boarding schools (3550). The selected students were clinically examined in the school and those having cardiac murmurs were assessed in the hospital (College of Medical Sciences-Teaching Hospital, Bharatpur) by trained cardiologists with transthoracic two dimensional echocardiography along with colour doppler. Age-specific rates (prevalence/thousand) of murmurs and structural heart disease (RHD and CHD) were determined. The age of the students ranged from 4 to 15 years with girls preponderance (Girl: Boy = 1.18:1). A significant cardiac murmur was observed in 345 students (45.00/1000) with similar prevalence in boys (45.71) and girls (44.58). Definite RHD was detected in 12 students (1.57/1000) and CHD in 30 patients (3.92/1000). The dominant rheumatic cardiac lesions were mitral regurgitation (3 in number) followed by mitral stenosis (2 in number) and aortic regurgitation (2 in number). Commonest CHD demonstrated were mitral valve prolapse (14 in number) followed by bicuspid aortic valve (9 in number), a trial septum defect-ostium secundum (3 in number), ventricular septal defect (2 in number) and severe pulmonary stenosis (2 in number). There is a low prevalence of RHD and CHD in school children in this region of central Nepal compared to previous Nepalese studies. Cardiac murmurs and RHD are more prevalent among low SES children in general school.
Desflurane induces more cerebral vasodilation than isoflurane at the same A‐line® autoregressive index level

Background: Clinical use of desflurane in neuroanesthesia remains under debate. Comparison of dose‐dependent vasodilatory properties between desflurane and isoflurane, the more traditional volatile agent for clinical neuroanesthesia, requires equianesthetic dosing of the agents. Reproducible neurophysiological measurements of the level of anesthesia in an individual, e.g. the A‐line® autoregressive index (AAI), can be used for an equipotent dosage of two volatile agents in the same individual.
Simultaneous localization and mapping for pedestrians using low-cost ultra-wideband system and gyroscope

Ultra-wideband (UWB) is a promising positioning system that has undergone massive research development in recent years. Most UWB systems assume prior knowledge on the positions of the UWB anchors. Without knowing the anchor positions, an accurate position estimate of a user is difficult. Hence, this paper presents a novel simultaneous localization and mapping (SLAM) approach for pedestrian localization using a UWB system, where the locations of the anchors are unknown. We fuse the distance estimates of the UWB system with heading information obtained from an inertial measurement unit (IMU). We evaluate the proposed algorithm based on measurements with a moving pedestrian and fixed anchors with unknown positions. The evaluations show that an accurate position estimation of both the pedestrian and the anchors is possible without any prior knowledge on the anchor positions.
Grid–SVC: An Improvement in SVC Algorithm, Based On Grid Based Clustering

Support vector clustering (SVC) is an important kernelbased clustering algorithm in multi applications. It has got two main bottle necks, the high computation price and labeling piece. In this paper, we presented a modified SVC method, named Grid–SVC, to improve the original algorithm computationally. First we normalized and then we parted the interval, where the SVC is processing, using a novel Grid–based clustering algorithm. The algorithm parts the intervals, based on the density function of the data set and then applying the cartesian multiply makes multi-dimensional grids. Eliminating many outliers and noise in the preprocess, we apply an improved SVC method to each parted grid in a parallel way. The experimental results show both improvement in time complexity order and the accuracy. Keywords—Grid–based clustering, SVC, Density function, Radial basis function.
Obstetric Profiles of Immigrant Women from Non‐English Speaking Countries in South Australia, 1981–1983

Summary: Obstetric profiles of non‐English speaking immigrant women in South Australia are presented to assist in planning for health services. They were derived from perinatal data routinely collected by midwives and neonatal nurses. The characteristics of 5,675 immigrant women were compared with those of a random sample of approximately 5% of Australian‐born women who delivered babies in 1981–1983 in South Australia. This study demonstrates that immigrant women tended to be urban dwellers and to deliver their babies in large metropolitan hospitals. They were less often from unemployed families but more often from those of low occupational status. They were older, with fewer teenagers and single women among them. They were of higher parity, and tended to commence antenatal care later. They had lower incidences of pregnancy hypertension and induced labour, but were more likely to have anaemia, antepartum haemorrhage and a Caesarean section. There were also important differences between the 7 largest immigrant groups. For example, the very high Caesarean section rate (36%) in Filipino women is of concern. Also, the mean birth‐weight of babies of Vietnamese women was 263g lower than that of babies of Australian‐born women. Support services need to be logistically located and address the findings of this study in a culturally acceptable way.
Theorizing the client—consultant relationship from the perspective of social-systems theory

Over the last few years research on management consulting has established itself as an important area in management studies. While, traditionally, consulting research has been predominantly a-theoretical, lately researchers have been calling for an exploration of different theoretical approaches. This article has been written in response to these calls. It explores a new perspective for theorizing the client—consultant relationship based on the theory of social systems by Niklas Luhmann. According to this approach, clients and consultants can be conceptualized as two autopoietic communication systems that operate according to idiosyncratic logics. They are structurally coupled through a third system, the so-called ‘contact system’. Due to the different logics of these systems, the transfer of meaning between them is not possible. This theoretical position has interesting implications for the way we conceptualize consulting, challenging many traditional assumptions. Instead of supporting the client in finding solutions to their problems, this perspective emphasizes that consulting firms can only cause ‘perturbations’ in the client’s communication processes, inducing the client system to construct its own meaning from it.
Helix‐coil transition of alanine peptides in water: Force field dependence on the folded and unfolded structures

The force fields used in classical modeling studies are semiempirical in nature and rely on their validation by comparison of simulations with experimental data. The all‐atom replica‐exchange molecular dynamics (REMD) methodology allows us to calculate the thermodynamics of folding/unfolding of peptides and small proteins, and provides a way of evaluating the reliability of force fields. We apply the REMD to obtain equilibrium folding/unfolding thermodynamics of a 21‐residue peptide containing only alanine residues in explicit aqueous solution. The thermodynamics of this peptide is modeled with both the OPLS/AA/L and the A94/MOD force fields. We find that the helical content and the values for the helix propagation and nucleation parameters for this alanine peptide are consistent with measurements on similar peptides and with calculations using the modified AMBER force field (A94/MOD). The nature of conformations, both folded and unfolded, that contributes to the helix‐coil transition profile, however, is quite different between these two force fields.

A non-linear learning & classification algorithm that achieves full training accuracy with stellar classification accuracy

A fast Non-linear and non-iterative learning and classification algorithm is synthesized and validated. This algorithm named the "Reverse Ripple Effect(R.R.E)", achieves 100% learning accuracy but is computationally expensive upon classification. The R.R. E is a (deterministic) algorithm that super imposes Gaussian weighted functions on training points. In this work, the R.R. E algorithm is compared against known learning and classification techniques/algorithms such as: the Perceptron Criterion algorithm, Linear Support Vector machines, the Linear Fisher Discriminant and a simple Neural Network. The classification accuracy of the R.R. E algorithm is evaluated using simulations conducted in MATLAB. The R.R. E algorithm's behaviour is analyzed under linearly and non-linearly separable data sets. For the comparison with the Neural Network, the classical XOR problem is considered.
The Impact of ICT and Networking on the Business Performance of One Tambon One Product Enterprises in Greater Bangkok and Metropolitan Areas

This study attempts to explore and examine OTOP entrepreneurs’ business performance through relationships with ICT adoption and entrepreneurial networks in greater Bangkok and metropolitan areas. Survey data were collected from a sample of 339 OTOP entrepreneurs and in-depth interviews of government officials, and key informants of OTOP entrepreneurs were conducted. The r esults from the empirical findings are: work experience, number of employees, ICT adoption and entrepreneurial networks have positive relationships with business performance. Further, business performance had an impact from work experience, number of employees, ICT adoption, and entrepreneurial networks. An increase in the work experience of the entrepreneur, an increase in the number of employees, an increase in the adoption and application of ICT, and an increase in entrepreneurial networkings were seen to increase business performance. The government should provide financial support, quality training and management, and create a conducive environment so that OTOP entrepreneurs can realize their full potential and maximize their contribution to the country’s economic development. OTOP entrepreneurs should utilize ICT and networks to strengthen their business performance. The government should have a choice of policies that will enable OTOP entrepreneurs to survive and to grow. The justification for such policies is that OTOP enterprises are major sources of job creation, innovation, and competitiveness. It is the government’s responsibility to support and promote entrepreneurs to enhance economic development. All involved in the OTOP Project for economic development should have integrated awareness and a holistic view to overcome challenges. การวจยครงนมวตถประสงคเพอศกษาความสมพนธของผลการดำเนนงานของผประกอบการวสาหกจในโครงการหนงตำบลหนงผลตภณฑกบการใชเทคโนโลยสารสนเทศและการสอสารและระบบเครอขายวสาหกจ ในเขตกรงเทพมหานครและปรมณฑล โดยจดเกบขอมลจากผประกอบการวสาหกจในโครงการหนงตำบลหนงผลตภณฑ จำนวน 339 รายและสมภาษณเจาะลกขาราชการและผประกอบการวสาหกจทเกยวของกบโครงการฯ ผลการวจยพบวา ประสบการณการทำงาน จำนวนพนกงาน การใชเทคโนโลยสารสนเทศและการสอสารและระบบเครอขายวสาหกจมความสมพนธกบผลการดำเนนงานซงเปนไปในทศทางเดยว กลาวคอ การมประสบการณการทำงานมากขน มจำนวนพนกงานเพมขน การใชเทคโนโลยสารสนเทศและการสอสารเพมขนและการมระบบเครอขายวสาหกจเพมขนทำใหผลการดำเนนงานเพมขน รฐบาลควรใหการสนบสนนดานการเงน การฝกอบรมและการบรหารจดการและสรางสภาพแวดลอมทเหมาะสมเพอใหผประกอบการวสาหกจในโครงการหนงตำบลหนงผลตภณฑไดรบรและเขาใจในสมรรถนะของตนและสนบสนนการพฒนาระบบเศรษฐกจของประเทศ ผประกอบการวสาหกจควรใชเทคโนโลยสารสนเทศและการสอสารและระบบเครอขายวสาหกจเพอสรางความแขงแกรงใหกบผลการดำเนนงาน รฐบาลควรมนโยบาลททำใหมผประกอบการวสาหกจในโครงการหนงตำบลหนงผลตภณฑมเพมขนและพฒนาตอไป นโยบายดงกลาวนเปนประโยชนเพราะผประกอบการวสาหกจในโครงการหนงตำบลหนงผลตภณฑเปนแหลงสำคญททำใหมการสรางงาน สรางนวตกรรมและการแขงขน รฐบาลมหนาทในการใหการสนบสนนและสงเสรมผประกอบการวสาหกจเพอสงเสรมและพฒนาเศรษฐกจ ผมสวนเกยวของในโครงการหนงตำบลหนงผลตภณฑจะตองรวมกนบรณาการความรและความสามารถเพอใหโครงการประสบความสำเรจ
Cloning and nucleotide sequence of the thrB gene from the cyanobacterium Calothrix PCC 7601

The cyanobacterium Calothrix PCC 7601 thrB gene, encoding homoserine kinase (EC 2.7.1.39), was cloned via complementation of an Escherichia coli threonine auxotroph, and its nucleotide sequence was determined. The comparison of the homoserine kinase amino acid sequences from Calothrix PCC 7601, E. coli K12 and Bacillus subtilis 168 indicates a closer relationship between cyanobacteria and bacillaceae than between cyanobacteria and enterobacteriaceae. Sequence analysis of the 5′ and 3′ flanking regions of the Calothrix thrB gene revealed the existence of a 169‐codon‐long open reading frame downstream from thrB: this sequence may be the second gene of a Calothrix thr operon. Two types of tandemly repeated sequences, sharing similarities with other prokaryotic transcriptional regulatory elements, were detected in the region upstream from the thrB gene.
Exporters, Spin-outs and Firm Performance

This paper analyzes the relationship between exporters, spin-outs and firm performance. A large body of research has shown that exporters perform better than non-exporters. But are also firms spawn out from exporters better than other new firms in terms of survival, productivity and growth? Using a panel of about 2,000 ex-employee starts ups, their parent companies and 10 000 other new firms in Sweden observed over a sequence of 5 years, we provide new evidence on spinouts as a channel of transferring knowledge from exporting firms to new ventures.

The Molecular Perspective: Restriction Endonucleases

The Oncologist 2002;7:82-83 www.TheOncologist. com We live in a remarkable age. Physicians now have an unprecedented range of options for helping their patients. Surgery and radiology are using advanced technologies to pinpoint treatments. Chemotherapeutic approaches are showing ever-greater effectiveness and specificity, approaching the goal of a “magic bullet. ” And we are now entering a time when we can make changes at the most basic level, introducing changes directly into the genetic code. Gene therapy, the ability to introduce new genes into living cells, holds great promise for the treatment of many diseases, including cancer. Restriction endonucleases are the molecules that spawned the field of biotechnology, the first of the many molecular tools that make gene therapy a reality. Bacteria build restriction endonucleases to protect themselves from attack by viruses. These enzymes cleave DNA at a specific sequence of nucleotides: for instance, one enzyme from Escherichia coli cuts the sequence GAATTC and another enzyme from Bacillus amyloliquefaciens will not cut it, but instead cuts the similar sequence GGATCC. Each species of bacterium protects its own DNA at its personal sequence by adding a bulky methyl group on a few of the bases, so only invading viral DNA, which does not have the protective methyl groups, is chopped up and destroyed. There are hundreds of forms of these restriction enzymes, made by different bacteria to cut DNA at different sequences. Although this may seem merely like a scientific curiosity worthy of a few lines in a textbook, restriction endonucleases are almost unbelievably useful. We could not have designed a more perfect molecule-sized tool to manipulate DNA. They are custom molecular scissors, allowing us to cut DNA into well-defined, perfectly specified pieces. Hundreds of different restriction endonucleases are available commercially: you merely pick the sequence that you want cleaved and then go to the catalog and find the enzyme from the proper species of bacteria. With these tiny molecular tools, perfected by evolution, we are able to reassemble DNA, cutting out genes of interest Fundamentals of Cancer Medicine The Oncologist
Clearance of biofilms from dental unit waterlines through the use of hydroperoxide ion-phase transfer catalysts.

OBJECTIVES The purpose of this research was to demonstrate the effectiveness of hydroperoxide ion-phase transfer catalyst (HPI-PTC) cleaners and disinfectants for maintaining dental unit waterlines free of planktonic organisms. METHOD AND MATERIALS Water samples were taken from 117 sites, which included a variety of dental units and samples from the sink faucets of most operatories. Samples were plated on appropriate bacteriologic media and incubated. The presence or absence of biofilms was confirmed by scanning electron microscopy. Twenty-two of the dental units were retrofitted with independent water systems; the cleaning procedure involved an overnight application of an HPI-PTC cleaner followed by a 2-minute water rinse. RESULTS Water from both the air-water syringe and the high-speed handpiece lines from all untreated units contained at least 6 x 10(2) colony-forming units per milliliter of planktonic or free-floating bacteria; the average was 1.4 x 10(5) CFU/mL. An initial 5% solution of HPI-PTC successfully cleared the lines of any apparent biofilm when applied for 3 consecutive days. Thereafter, once weekly use of the cleaner maintained the dental unit water supplies free of significant numbers of planktonic organisms. CONCLUSION Routine weekly use of an HPI-PTC cleaner controlled dental unit waterline biofilm and reduced, with minimum effort, the microbial contamination level of water used for patient treatment to less than 200 CFU/mL.
DETECTION FRAUD OF FINANCIAL STATEMENT WITH FRAUD TRIANGLE

This study aims to obtain empirical evidence to detect fraudulent financial statements based on the perspective of fraud triangle. Fraud triangle theory proposed by Cressey (1953) states that there are three conditions that are always present in every instance of fraud, pressure, opportunity and rationalization. Based on the proposed theory of fraud triangle. Fraudulent financial reports on this research is proxied by earnings management. Variables variables used of fraud triangle is composed of the pressure of financial stability (AGROW), external pressure by proxy leverage ratio (LEV)), Financial Targets with proxy return on assets (ROA) and the ineffectiveness monitoring by proxy the ratio of independent board (BDOUT). Data on indications of fraud financial report in this study are listed in LQ45 stocks. The population in this study is a company registered in LQ45 in periode 2012 –2013. The selection of the sample in this study was conducted with a purposive sampling method and obtained samples are 35 companies listed in the LQ45 both contain elements of fraud in the financial statements and did not commit fraud in the financial statements (by industry and total assets) to perform financial statement presentation back . In this research, hypothesis testing is done using multiple linear regression method. Results of this study indicate that the stability of the financial variables that proxy the asset growth rate (AGROW) has a positive influence by fraud financial statements, financial targets proxied by profitability ratios (ROA) has a positive relationship with fraudulent financial statements, financial effectiveness is proxied by the ratio of the commissioners (BDOUT) has a positive relationship with fraudulent financial statements, the external pressure is proxied by Leverage Ratio (LEV) has a negative relationship with financial statement fraud.
Academic Social Networks Affecting the Adoption of E-Learning in Turkey

This article reports findings from an ethnographic study of e-leaming adopters in Turkey and examines ways in which cultural factors shape the adoption and use of infonnation technology for online teaching. This research focuses on influential early adopters in the tertiary education sector in Turkey who have become change agents by inspiring small networks of their peers into e-learning. The study examines the operation of trust and inspiration in networking and teamwork in the Asian academic environment. A key finding of this research is that the early adopters of e-Ieaming tend to become change agents in small groups and networks. This research sheds light on the mechanisms by which the process of e-Ieaming adoption relies on social networks and connections.
A simple and efficient approximation to the modified Bessel functions and its applications to Rician fading

In recent days, relay assisted cellular networks are gaining more importance in research and development because of the recent adoption of new communication standards with relaying and cooperation communication. This has introduced a multichannel diversity along with the multiuser diversity and the channel aware dynamic resource allocation models. The issue of the optimal location of relays has risen especially when dedicated relays are used as the standard proposes instead of the cooperative model of the users. In this paper, we study the optimal location of a single relay. Furthermore, we study the effect of changing the number of users on the optimal location of the relay. The effect of adding multiple relays to the system is examined. The optimal locations are examined when the relay channels are the only channels to be used by the system and when the direct channel (DT) is also available. The problem formulation assumes, Rayleigh block faded channels, half duplex regenerative (repetition coding) decode-and-forward (DF) relaying strategy, long-term average total transmitted power constraint and orthogonal multiplexing of the users messages within the channel blocks. New simple and accurate approximations to the modified Bessel functions of the first kind, zeroth order I0 (z) and first order I1 (z) are presented. The new proposed approximations are given as a simple finite sum of scaled exponential functions. Comparisons are made between the exact functions, classic approximations, and the new approximation in terms of simplicity and accuracy. The new approximation proves to be sufficiently accurate to bridge the gap between the classic large and small argument approximations and has potential applications in allowing one to analytically evaluate integrals containing Modified Bessel Functions, yielding simple closed-form solutions. A generalized closed-form expression for the average bit error rate over Nakagami-n (Rice) fading, and Rayleigh fading as a special case, are derived as sample applications, and the results are compared with Monte Carlo Simulation, where a very good matching is achieved.
