A Three-Phase Inductive Power Transfer System for Roadway-Powered Vehicles

The development of a new three-phase bipolar inductive power transfer system that provides power across the entire width of a roadway surface for automatic guided vehicles and people mover systems is described. A prototype system was constructed to verify the feasibility of the design for a number of moving loads (toy cars). Here, 40 A/phase is supplied at 38.4 kHz to a 13-m-long test track. Flat pickups are used on the underside of each vehicle to couple power from the track to the vehicle. Finite element modeling software was used to design the geometrical position of the track cables and to predict the power output. This design resulted in a considerably wider power delivery zone than possible using a single-phase track layout and has been experimentally verified. Mutual coupling effects between the various track phases require additional compensation to be added to ensure balanced three-phase currents.
Multi-sized Output Cache Controllers

This project describes the design of a Multi-sized Output Cache Controller that will handle 2Kbyte 16 ways with 4 word block size cache. A cache controller is a device that used to sequence the read and write of the cache storage array. Most of modern microprocessor is designed with multiple core architecture that will lead to massive traffic of cache data transfer. By taking the advantage of using temporal locality and spatial locality to the cache, the problem can be solved. With this solution, a controller that capable to handle huge amount of way and block size need to be designed. This design will be implemented using Xilinx software. It was developed base on Verilog coding. Using the same software, a test bench was constructed to test the functionality of the controller. This cache controller consists of four stages, from request to read data. It had the capability to read and write to different agent on various output data size from 1byte till 16 byte.
An empirical study of morphing on network traffic classification

Network morphing aims at masking traffic to degrade the performance of traffic identification and classification. Several morphing strategies have been proposed as promising approaches, very few works, however, have investigated their impact on the actual traffic classification performance. This work sets out to fulfill this gap from an empirical study point of view. It takes into account different morphing strategies exerted on packet size and/or inter-arrival time. The results show that not all morphing strategies can effectively obfuscate traffic classification. Different morphing strategies perform distinctively, among which the integration of packet size and inter arrival time morphing is the best, and the packet size based method is the worst. The three classifiers also exhibit distinct robustness to the morphing, with C4.5 being the most robust and Naive Bayes being the weakest. In addition, our study shows that classifiers can learn nontrivial information merely from the traffic direction patterns, which partially explains the weakness of packet size based morphing methods.
The lexicon-based sentiment analysis for fan page ranking in Facebook

The traditional methods to rank a Facebook fan page only rely on the user engagement including the number of posts, comments, and “likes”. The polarity of each comment, which can be positive, neutral, or negative, is ignored in these methods. In this paper, we propose a content-based ranking method in which the user engagement and the comment polarity are all considered. The user comment is analyzed using a lexicon-based approach. We apply the proposed method for the real Facebook dataset collected using the Social Packets crawler. The result shows that the ranks of pages estimated by our method is close to the ranks estimated by engagement based method. More importantly, by concerning the comment polarity, our page ranking is more accurate regarding user opinion.
Conservatism of Social Work

This article addresses the charge that social workers, like the charity workers before them, disseminate the conservative values of a middle-class culture. Although the underlying conservative social and political context of social work practice is not denied, the author objects to equating social work with charity work, to equating professional social work thinking with social agency thinking, and to the implication of monolithic thinking within the profession. The history of child welfare is used to demonstrate the profession's efforts to differentiate itself from its lay and organizational ties as it has attempted to develop a unifying practice methodology.
Lossless image coding by cellular neural networks with minimum coding rate learning

In this paper, a novel lossless image coding scheme using the cellular neural network (CNN) is proposed. From the viewpoint of the optimal lossless coding, our method is optimized for not only mean squared error (MSE) but also a coding rate. The key idea of this work is that the local structure of an image is modeled by six types of CNN templates in order to achieve high prediction performance, and the CNN parameters that gives prediction characteristic are decided by the supervised minimum coding rate learning. Moreover, in the entropy coding layer, the prediction residuals are coded by an adaptive arithmetic encoder with context modeling for high coding efficiency. The effectiveness of proposed algorithm is confirmed by some computer simulations of various standard test images, and its performance is compared with that of conventional hierarchical coding schemes having scalability.
Breastfeeding Patterns in Relation to Thumb Sucking and Pacifier Use

Objectives. To analyze the influence of thumb sucking and pacifier use on breastfeeding patterns in exclusively breastfed infants, on the duration of exclusive breastfeeding, and on the total breastfeeding duration. Study Design. Descriptive, longitudinal, prospective study. Setting. The subjects were recruited from a population of 15 189 infants born in the maternity ward at the University Hospital, Uppsala, Sweden between May 1989 and December 1992. Study Population. 506 mother–infant pairs. Methods. Daily recordings by the mothers on infant feeding from the first week after delivery through the duration of the study. Fortnightly home visits with structured interviews by a research assistant. Results. Pacifier use was associated with fewer feeds and shorter suckling duration per 24 hours, shorter duration of exclusive breastfeeding, and shorter total breastfeeding duration compared with no pacifier use. These associations were not found for thumb sucking. The possible negative effects of pacifiers on breastfeeding seemed to be related to the frequency of their use. Maternal age and education only slightly modified the association between pacifier use and breastfeeding duration. Conclusions. More frequent use of a pacifier was associated with shorter breastfeeding duration, even among a group of mothers who were highly motivated to breastfeed. breastfeeding duration, breastfeeding pattern, exclusive breastfeeding, pacifier use, thumb sucking.
Acupuncture for Chronic Low Back Pain: Diagnosis and Treatment Patterns Among Acupuncturists Evaluating the Same Patient

Background. There is increasing need to examine the effectiveness of acupuncture and other alternative therapies for common conditions. However, little attention has focused on the variability in acupuncturists' assessment, diagnosis, and treatment patterns. Methods. Seven office-based acupuncturists practicing Traditional Chinese Medicine evaluated the same patient with chronic low back pain and provided data regarding principal assessment techniques, diagnoses, and therapeutic recommendations. Results. A high diagnostic agreement existed among 5 of 7 acupuncturists. However, recommended treatments included varying numbers and locations of acupuncture points. Recommendations varied between 5 and 14 points requiring 7 to 26 needles, since many points were intended for bilateral application. Of 28 acupuncture points selected, only 4 (14%) were prescribed by two or more acupuncturists. Most recommended various forms of adjuvant heat. Conclusions. Seven acupuncturists agreed considerably in the diagnoses for the same patient with chronic low back pain, but treatment recommendations varied substantially. Clinicians and researchers must recognize treatment recommendation variations and the challenges they present for study design and interpretation.
Are Perceived Sensory Dimensions a Reliable Tool for Urban Green Space Assessment and Planning?

Abstract Environmental psychologists have developed varying methods for landscape assessment according to how it is perceived and experienced. In the Nordic countries, eight perceived sensory dimensions are increasingly being used as a methodological framework for expert assessments. These are serene, nature, rich in species, space, prospect, refuge, social and culture. Using an onsite questionnaire distributed to green space visitors in Helsingborg, Sweden, this study is the first to examine the representation of the eight sensory dimensions in different types of urban green spaces as experienced by lay people and their relationships with green space attributes. The results showed that (1) prospect then serene and space were the most common, and culture and social the least; (2) the experience of the sensory dimensions varied across the six study sites and was related to their diversity of biotopes and overall size; and (3) respondent experience of the sensory dimensions was consistent across gender, age and frequency and type of recreational use. These results grant legitimacy to the method in assessment and mapping of recreational experience of urban green space.
Namibia's health policies and strategies.

Finland has helped Namibia to pass through the transition period after independence in March 1990. For example, it helped develop a census to provide baseline health and demographic data so the government can proceed with planning its health policy. A goal is to switch from the curative health system it inherited to a primary health care system so as to achieve Health for All by the year 2000. Indeed the government assures free health services to all citizens. The Ministry of Health and Social Services has identified 4 strategies to achieve this goal: granting health promotion and prevention top priority; increase use of information, education, and communication; community participation; and intersectoral cooperation. Morbidity in Namibia is high, e.g., the tuberculosis, measles, and malaria rates are 295, 281, and 473/100,000 population, respectively; the growth of 33% of the children is stunted; and 6% suffer from severe malnutrition. Namibia is dependent upon food imports because parts of Namibia receive very little rain, resources are not equally distributed, landlords do not live near their land holdings, and poverty. The government plans to hold a conference on land to discuss land ownership. The government intends to improve women's status which in turn will improve their, their children's, and the population's health. The constitution guarantees women's rights. Various priority areas of the Ministry include immunization, maternal health (prenatal, intrapartum, and postnatal care), and family planning. Namibia has hosted workshops on these topics and has organized a national AIDS committee which has held 9 workshops on AIDS. The government recognizes that the health of the population depends on national economic development as well as the state of education, housing, agriculture, sanitation, and communication.
Exploiting dendritic autocorrelogram structure to identify spectro-temporal regions dominated by a single sound source

Autocorrelograms exhibit tree-like structures whose spines are located at a delay of 1/F0. This paper exploits the dendritic autocorrelogram structure for the identification of spectro-temporal regions dominated by a single periodic sound source in monaural acoustic mixtures. Each frame of the mixture is first segmented into different sound sources in the autocorrelogram domain. Local pitch estimates are formed for each source and used as a cue for temporal integration. A confidence score is computed for each time-frequency pixel in the grouped regions to determine its probability of belonging to the group. The system is evaluated using simultaneous speech in a coherence measuring experiment and also employed within an ASR system where it produces improved results for the Interspeech 2006 Speech Separation Challenge. Index Terms: speech separation, correlogram, multipitch tracking.
Finite state machine induction using genetic algorithm based on testing and model checking

In this paper, we describe the method of finite state machine (FSM) induction using genetic algorithm with fitness function, cross-over and mutation based on testing and model checking. Input data for the genetic algorithm is a set of tests and a set of properties described using linear time logic. Each test consists of an input sequence of events and the corresponding output action sequence. In previous works testing and model checking were used separately in genetic algorithms. Usage of such an approach is limited because the behavior of system usually cannot be described by tests only. So, additional validation or verification is needed. Calculation of fitness function based only on verification do not perform well because there are very few possible values of fitness function (verification gives only "yes" or "no" answer). The approach described is tested on the problem of finite state machine induction for elevator doors controlling. Using tests only the genetic algorithm constructs the finite machine working improperly in some cases. Usage of verification allows to induct the correct finite state machine.
Staging of the neck in patients with oral cavity squamous cell carcinomas: a prospective comparison of PET, ultrasound, CT and MRI.

BACKGROUND The choice of treatment in patients with oral malignancies depends on accurate pretreatment staging and particularly the detection of lymph node involvement. Therefore staging of the neck should be as accurate as possible. PATIENTS One hundred and six patients with histologically proven squamous cell carcinoma of the oral cavity. STUDY DESIGN In a prospective study, PET using fluoro-desoxy-glucose (18F-FDG), ultrasound, CT and MRI of head and neck were compared with the postoperative histologic tissue evaluation. Two thousand one hundred and ninety-six neck lymph nodes of 106 patients were investigated. In all patients the tumour was resected and a lymph node dissection was performed. RESULTS The diagnostic procedures showed the following results when compared with the histological findings: PET: sensitivity 70%, specificity 82%, accuracy 75%; Ultrasound: 84%, 68%, 76%; CT: 66%, 74%, 70%; MRI: 64%, 69% 66%. Thus PET showed the highest specificity while ultrasound had the highest sensitivity compared with the other staging procedures. A nonsignificant correlation was found between the size of a lymph node metastasis and the ability to detect it. In 10 patients, second primary tumours or distant metastases were detected by PET only. CONCLUSION Due to the high number of small lymph node metastases from oral cavity carcinoma, the non-invasive neck staging methods are limited to a maximum accuracy of 76%. Elective neck treatment should be mandatory for all patients with squamous cell carcinoma of the oral cavity.
Delay constrained throughput optimised joint scheduling and link adaptation scheme based on imperfect channel state information

This study presents novel joint scheduling and link adaptation schemes (JSL) to maximise a weighted sum of throughputs of wireless links, while their possibly different minimum required throughputs and packet error rate (PER), average power and delay constraints are provisioned. Weights are assigned based on the importance and requirements of the links. Notable features of the proposed scheme in comparison with the previously presented utility based scheduling schemes are: (a) in the designed scheme a statistical bound is presented for the delay instead of average delay constraint or long term queuing delay behaviour, (b) designed transmission scheme utilises adaptive modulation and coding provisioning PER constraint and may be integrated with H automatic repeat request in data link layer to provide error free communication, (c) the presented schemes are designed based on imperfect signal-to-noise ratio (SNR) estimate of the links. In addition to an analytical approach, a JSL scheme based on sub-gradient projection (JSL-SP) is presented in which there is no need to have SNRs probability density functions. Numerical results demonstrate how the proposed JSL schemes outperforms the benchmark schemes and effectively meets various user's requirements.
Integral characteristics of MISTY2 derived by division property

Integral cryptanalysis is one of the most powerful attacks on symmetric key ciphers. Todo proposed a new technique named division property to find efficient integral characteristics, and showed that the full-round MISTY1 was attackable faster than exhaustive search [22]. In this paper, we apply it to the symmetric key block cipher MISTY2, which wasn't discussed in [22]. As a result, we found the 7-round integral characteristics of MISTY2. We compare them to the known higher order differential characteristics. Both characteristics are almost the same.
Can the zero-lag filter be a good smoother?

The problem of constructing low complexity suboptimal fixed-lag estimators is discussed. First, it is shown that any optimal fixed-lag estimator structure generally performs better if more delay is accepted than the designed lag. As this holds for any design lag including zero-lag, it is demonstrated that the zero-lag filter treated as a suboptimal fixed-lag smoother has an error considerably lower than the conventional zero-lag error. A near optimal fixed-lag smoother is then found by a straightforward extention of the zero-lag filter. Several examples are considered. Finally, the usefulness of the conventional fixed-lag mmse criterion is discussed.
Age Discrimination and Personnel Psychology: A Review and Synthesis of the Legal Literature with Implications for Future Research.

One hundred and fifty-two court cases were reviewed to determine the standards set by the courts for establishing a claim of age discrimination under the Age Discrimination in Employment Act, as amended. Fifty-three are discussed. Two major issues were examined in Part 1 of the review: (1) the type and extent of the evidence sufficient to establish a complaint of age discrimination and (2) available defenses against age discrimination complaints. Part 2 discussed employer strategies for averting and/or dealing with discrimination complaints. Also discussed were the research-related implications of the age discrimination case law, as well as the role of professionals in future research.
Activity of benzimidazoles against Dientamoeba fragilis (Trichomonadida, Monocercomonadidae) in vitro and correlation of beta-tubulin sequences as an indicator of resistance

Recently, Dientamoeba fragilis has emerged as a significant and common enteropathogen. The majority of patients with dientamoebiasis present with gastrointestinal complaints and chronic symptoms are common. Numerous studies have successfully demonstrated parasite clearance, coupled with complete resolution of clinical symptoms following treatment with various antiparasitic compounds. Despite this, there is very little in vitro susceptibility data available for the organism. Benzimidazoles are a class of antiparasitic drugs that are commonly used for the treatment of protozoan and helminthic infections. Susceptibility testing was undertaken on four D. fragilis clinical isolates against the following benzimidazoles: albendazole, flubendazole, mebendazole, nocodazole, triclabendazole and thiabendazole. The activities of the antiprotozoal compounds at concentrations ranging from 2 μg/mL to 500 μg/mL were determined via cell counts of D. fragilis grown in xenic culture. All tested drugs showed no efficacy. The beta-tubulin transcript was sequenced from two of the D. fragilis isolates and amino acid sequences predicted a susceptibility to benzimidazoles. This is the first study to report susceptibility profiles for benzimidazoles against D. fragilis, all of which were not active against the organism. This study also found that beta-tubulin sequences cannot be used as a reliable marker for resistance of benzimidazoles in D. fragilis.
Tn, a carcinoma‐associated antigen, reacts with anti‐Tn of normal human sera

Tn antigen is the immediate precursor of the carcinoma (CA)‐associated T antigen; both are masked in non‐CA tissues. Tn antigen was detected by absorption of human anti‐Tn antibody in 46 of 50 primary breast CAs and in all 6 metastases originating from Tn‐positive primary CAs. Thirteen of 25 (52%) anaplastic CAs, but only 2 of 15 (13%) well differentiated CAs had more Tn than T; 1 anaplastic CA had neither antigen. Eighteen of 20 benign breast lesions had no Tn; the 2 positive lesions were premalignant. All 19 breast CAs, studied immunohistochemically, reacted strongly with human polyclonal anti‐Tn; benign or normal glandular tissues had minimal or no reactivity. Among live cancer cell lines, the most malignant sublines had more Tn than T on their cell surfaces. Preliminary studies with rodent monoclonal anti‐Tn and anti‐T antibodies gave immunohistochemical reactivity patterns similar to those of the polyclonal antibodies, but the former were less sensitive in absorption tests. Tn is a CA marker that promises to be useful in tumor detection.
Capacity bounds for the Gaussian interference channel with transmitter cooperation

We obtain a new outer bound on the capacity region of the two-user interference channel with generalized feedback (IC-GF). This outer bound is based on the idea of dependence balance which was proposed by Hekstra and Willems [1]. We explicitly evaluate our outer bound for the Gaussian IC with user-cooperation (IC-UC), where each transmitter receives an additive white Gaussian noise corrupted version of the channel input of the other transmitter [2]. We show that for all non-zero values of cooperation noise variances, our outer bound strictly improves upon the cut-set outer bound.
Leakage current variability in nanometer technologies

The dramatic increase in leakage current coupled with the large increase in variability in highly scaled CMOS technologies, pose a major challenge for future IC design. Leakage variability can not be neglected any more, due to the increase of leakage power percentage in modern ICs. In this paper, the main sources of variations and how they impact leakage current are discussed. Design guidelines to reduce variability based on several leakage reduction techniques are also presented. It is shown that reverse body bias technique increases leakage variability due to its deteriorating effect on drain-induced barrier lowering (DIBL). This paper highlights the need for further efforts in the area of statistical leakage estimation, as well as variation tolerant circuit techniques.
Boundary Spanners Revisited

While collaborative change models are gaining momentum in human services, more needs to be known about those leading the changes in a contemporary context. The professional experiences of those who work among diverse, fragmented, even rival factions, often without formal authority, and manage to facilitate cross-system cooperation among multiple partners remain under explored. They represent the evolution of a rich and varied history of models of leadership in social networks and social movements. In this qualitative study, leaders from the Reclaiming Futures initiative reflect on their roles in collaborative efforts to improve substance abuse treatment and community involvement in juvenile justice. Findings revealed the characteristics and strategies of successful boundary spanners — valuable for those engaged in such work and for future workforce development.
