Integrated ZVS DC–DC converter with continuous input current and high voltage gain

An integrated zero-voltage-switching (ZVS) DC–DC converter with continuous input current and high voltage gain is proposed. The proposed converter can operate with soft switching, a continuous inductor current and fixed switching frequency. The voltage stress of the power switches is relatively low compared to the output voltage. Moreover, soft-switching characteristic of the proposed converter reduces switching loss of active power switches and raise the conversion efficiency. The reverse-recovery problem of output rectifiers is also alleviated by controlling the current changing rates of diodes with the use of the leakage inductance of a coupled inductor. The operation and performance of the proposed DC–DC converter were verified on an 115 W experimental prototype operating at 100 kHz.
Efficiently combined structure of smart antenna and interference canceller using symbol reliability

The authors present an efficiently combined structure of a smart antenna and a partial interference canceller (IC). Two methods are proposed to estimate proper fractional weights for the partial IC. The first method improves the performance by preventing performance degradation of the IC owing to incorrect symbol decision using adaptive fractional weights. The second method improves performance by reducing the degrading effect of the partial IC, using modified fractional weights. Simulation results show that the proposed methods outperform a combined structure based on weight correlation.
Circulating levels of acute-phase proteins, heat shock protein 70, and corticosterone in the serum of developing chick embryos and newly hatched broiler chicks

Abstract Acute-phase proteins (APPs) are known to mediate the body's first line of defence against external insults in poultry and there is a growing interest to use the proteins to diagnose poultry health and physiological status. However, there is no report describing APPs during the prenatal and neonatal stages in poultry. The objectives of the study were to determine the presence and circulating concentrations of APPs in the embryos, and newly hatched chicks. Cobb 500™ eggs were incubated under a standard condition for 21 d. Blood samples were collected from embryos on days 14 (ED 14), 16 (ED 16), and 18 (ED 18) of incubation as well as newly hatched chicks to determine serum levels of corticosterone (CORT), alpha-1 acid glycoprotein (AGP), ceruloplasmin (CPN), and heat shock protein 70 (Hsp70). Both CORT and CPN showed a dramatic increase from ED 14 to ED 16 (p < .0001) but declined at ED 18 (p = .0004). The newly hatched chicks had elevated CORT (p < .0001) and CPN (p < .0001). Serum AGP rose from ED 14 to ED 18 and was followed by a sharp fall in the newly hatched chicks (p = .0074). Serum concentrations of Hsp70 were consistently elevated across the embryos' developmental stage and remained high in the newly hatched chick (p < .0001). In conclusion, APPs were detected in the blood of chicken embryos and neonates for the first time and the levels vary according to the development stage. These results have raised the need to better understand the physiological relevance of APPs in developing embryos and newly hatched chicks. Highlights Acute-phase proteins were detected and quantified in the circulation of developing chicken embryos and newly hatched chick for the first time. The magnitude of production of acute-phase proteins varied according to developmental stages. Acute-phase proteins may be of physiological relevance for the developing chicken embryos.
Lilith: A Rabbinic Projection of the Demonic Female

Why has the ancient Sumerian myth of the demon goddess Lilith become part of Jewish lore? Rabbinic sages (100 C.E. to 600 C.E.) applied midrash, a method of Jewish textual analysis, to the original biblical creation story to validate the position that Eve was Adam’s equal partner. Why did the rabbinic sages of the Talmud feel the compulsion to augment the biblical story of Adam and Eve with the Near Eastern myth of the dark feminine of Lilith? These questions are addressed using object relations theory and the Jungian archetypes of the Great Mother and the anima. The lens of psychological theory shows that this mythic goddess has the potential to re-emerge from the depths of the unconscious.
Studies on a novel flip-chip interconnect structure. Pillar bump

Pillar bump is a novel interconnect structure, including non-reflowable base and a reflowable cap like a pillar shape. In this study, pillar bump with copper base and Sn63/Pb37 eutectic solder cap is processed via electrolytic plating. Based on whether flat eutectic cap is reflowed prior to assembly, pillar bump is further split into two categories, namely pre-reflowed and non-reflowed, respectively. Assembly feasibility assessment as well as bump integrity evaluation are carried out. Bump shear test is conducted for both before and after reliability and failure mode is characterized via SEM and EDX. Furthermore, a 10 mm/spl times/10 mm test chip having 180 Cu/eutectic solder pillar bumps with 0.2 mm pitch is assembled onto BT substrate via no clean flux and subsequently underfilled. The results show that pillar shape is still maintained after assembly that can meet fine pitch requirement. No shear strength deterioration after moisture sensitivity preconditioning and 1000 thermal cycle test (TCT, -40/spl deg/C/spl sim/125/spl deg/C) has been observed. EDX spectra indicate fracture has occurred in the interfacial region between Al and silicon, not arising from bumping process. Furthermore, bump integrity is intact after package level reliability test under the same conditions as above. Stress simulation results lead to conclusion that maximum shear stress occurs in copper pillar portion with average range of 40/spl sim/50 MPa that is much below the shear strength of copper.

Moral Development in Young Children Exposed to Domestic Violence: The Case for the Proactive Role of the Therapist

ABSTRACT Ample evidence shows that exposure of young children to domestic violence may endanger children’s social-emotional development. Yet limited attention has been devoted to ways of specifically addressing issues of moral development in therapy. We highlight the need to address the potential harmful effects of domestic violence on the child’s moral development, within the context of the child’s relationship with the non-offending parent. We suggest that therapists assume a proactive role in identifying and addressing both the child’s and custodial caregiver’s feelings, perceptions and values relevant to the immoral acts of the perpetrator caregiver. Proactively addressing potential distortions seems essential, even though such a purportedly judgmental position may arouse uneasiness amongst therapists. Reviewing cases from Child-Parent-Psychotherapy with families exposed to domestic violence, we identify six recurring themes, indicating risk to children’s moral development. Themes include identification with the aggressor, positive feelings toward the perpetrator leading to excusing the violent acts, ambivalence toward the observance of social rules, and difficulties with empathy, guilt, and remorse. Together with the enlisted support of the custodial caregiver, these provide opportunities for the therapist to clarify and repair moral perceptions and feelings, denoting a clear moral stance, thereby contributing to the prevention of intergenerational cycles of violence.
Multi-class SVM based network intrusion detection with attribute selection using infinite feature selection technique

Abstract An intrusion detection mechanism is a software program or a device that monitors the network and provides information about any suspicious activity. This paper proposes a multi-class support vector machine (SVM) based network intrusion detection using an infinite feature selection technique for identifying suspicious activity. Single and multiple classifiers generally have high complexity. To overcome all the limitations of single and multiple classifiers, we used a multi-class classifier using an infinite feature selection technique, which performed well with multiple classes and gave better results than other classifiers in terms of accuracy, precision, recall, and f_score. Infinite feature selection is a graph-based filtering approach that analyses subsets of features as routes in a graph. We used a standard dataset, namely the UNSW_NB15 data set generated by the IXIA perfect-storm tool in the Australian Centre for Cyber Security. This dataset has a total of nine types of attacks and 49 features. The comparative analysis of the manuscript work is done against eight different techniques, namely, hybrid intrusion detection system (HIDS), C5, one-class support vector machine, and others. The proposed work gave better simulation results using the 2015a Matlab simulator.
The protective effect of non-thermal plasma against gamma irradiation in albino rats

ABSTRACT Background, plasma-activated water (PAW) is generated by exposing water to the fourth state of matter (plasma). Plasma emits several kinds of reactive nitrogen and oxygen species (RNOS). This wealth of active species potentiates the PAW modulation of gamma radiation-induced oxidative stress, which is the most likely cause for DNA damaging effect and/or cell death following gamma irradiation. Aims, this study is an endeavor to investigate the role of oral administration of PAW, against high dose of gamma irradiation. Methods, tap water was exposed to plasma jet under consideration delivering a plasma dose of 0.425 J/cm2. Rats, were divided into three groups, normal control ‘G1,’ group ‘G2’ including rats accessed to normal tap water and third group ‘G3’ including rats accessed to PAW. Each group drank the designated water for 60 consecutive days. After 60 days, the second and third groups were irradiated with a single dose of 7 gray gamma rays and anesthetized then sacrificed 24 following the irradiation. Blood samples were collected and assayed for DNA damage detection using comet assay. Biological functions including blood count, liver, and kidney function as well as oxygen and glucose levels were also assayed in the blood of all rats in the three considered groups. Results, although exposure to this dose of gamma radiation showed an adverse effects on rats accessed to normal tap water at both cellular and organ level, PAW group remained highly protected as was clearly shown by their cellular and biochemical parameters. Conclusions, our findings suggest that, PAW is considered a potentially promising technique for combating the acute effects of high radiation doses that damage DNA as well as impaired some biological functions. This could increase and support the hope in utilizing PAW as safer, economic, and efficient drinking water as radio-protective agent in expected wide scales.

Multiple-camera lane departure warning system for the automotive environment

The increasing trend towards the use of image sensors in transportation is driven both by legislation and consumer demands for higher safety and a better driving experience. Awareness of the environment that surrounds a vehicle can make driving and manoeuvring of the vehicle much safer for all road users. The authors present an image-processing method to detect lane departures using video taken from multiple optical cameras that is specifically designed to be in accordance with proposed automotive lane departure warning standards. This multi-camera system is more robust to errors caused by lane marking occlusions, sensor failure and glare that single camera systems can suffer from. The system uses a novel lane marking segmentation algorithm in accordance with international standards for lane markings. This method does not demand the high computational requirements of inverse perspective mapping (IPM) unlike methods proposed in related research. The authors present a method for lane boundary modelling based on subtractive clustering and Kalman filtering, which is within the constraints of automotive standards. Finally, using the cameras intrinsic and extrinsic parameters, the width of the vehicle and guidelines issued by the International Organisation for Standardisation, the authors show how lane departure can be identified. Results are presented that verify the system's high detection rate and robustness to various background interference, lighting conditions and road environments.
The use of the relation between relative force and endurance time

The relation between relative force (i.e., the actual force relative to the maximal voluntary force) and endurance time (i.e., the time the force can be maintained) is employed in a number of methods for ergonomics research. The aim is to assess the development of localized muscular fatigue as a consequence of isometric contractions and to compare activities regarding both the intensity and the duration of the isometric contractions exerted. The main assumption underlying this approach is that the relation is identical for different muscles and in different situations. Several anatomical and physiological factors contributing to variation in the relation are discussed and the consequences of this variation for the validity of the methods employing the relation are quantified. From this analysis, it appears, that the use of the relation between relative force and endurance time with the assumption mentioned leads to unreliable results. Therefore assessment of isometric contractions in labour situations wil.
A user-centred design process to develop technology to improve sleep quality in residential care homes

Poor sleep is common amongst older people living in residential care facilities. Solutions based on pharmacological therapies and improved nursing care have been investigated, but to date no co-ordinated analysis of the potential of technology to improve sleep quality has been undertaken in this context. To explore this area, this study applied a four-stage user-centred design process, which included identification and prioritisation of areas of need; exploration of design requirements; and development of physical prototypes. A relational model has been developed mapping major factors that contribute to poor sleep to specific areas of user need. Potential solutions to address difficulties with nocturnal anxiety and relaxation were identified, refined, developed and trialled with participants. Results indicate that the solutions may help improve sleep quality and provide evidence of the usefulness of the user-centred design process.
COMPARATIVE STUDY OF MUSCLE FATIGUE IN TABLE TENNIS TRAINING - AN OUTLINE

Table tennis is characterized with intermittent intervals of explosive (anaerobic) muscle activity, being the cause for use of interval training as the most suitable training method. Performance in the game is a function of the state of the neuromuscular system, i.e. its condition of (non)fatigue. A study has been conceptualized where top young players are monitored through kinematic, kinetic and surface EMG variables when performing a repetitive maximal forehand top-spin movement, practicing with a table tennis robot, in such a dynamics and duration as to induce fatigue. Sequences of 12 shots are followed by 10 second rest periods, and this is to be repeated during an overall time of 20 intervals. M. deltoideus anterior, m. deltoideus medialis, m. biceps brachii and m. pectoralis major are to be monitored, unilaterally. Kinematics of the upper body is to be measured using an ELITE system (Zagreb) or a VICON system (Vienna) respectively, ground reaction forces (GRF) using force plates (Kistler). Changes in time patterning of EMG signal waveforms are expected, while the decrease of the median frequency of the surface EMG power spectrum is to be used as a criterion of local muscle fatigue. Modifications of both, neuro-muscular and kinematic / kinetic patterns, together with decrease of performance are expected to appear with fatigue.
An auxiliary quasi-resonant tank soft-switching inverter

An auxiliary quasi-resonant DC tank (AQRDCT) inverter is presented for achieving soft-switching. An AQRDCT circuit is coupled directly across a DC bus to the inverter to generate a quasi-resonant DC bus voltage. It consists of two auxiliary switches connected in the common phase leg fashion as an auxiliary switch leg, two resonant capacitors connected in series as a resonant leg, a pair of DC capacitors connected in series as a DC tank, and a resonant inductor in series with the lower device of the auxiliary switch leg. The AQRDCT circuit resonantly brings the DC bus voltage to zero in order to provide a zero-voltage switching interval for the main inverter to switch, then quickly rebounds back to the DC tank voltage after the main inverter changes state. The auxiliary switches are turned on and off softly as well. The AQRDCT circuit absorbs only ripples of the inverter DC bus current, thus having less current stress. In addition, since the AQRDCT circuit is coupled in parallel with the DC power supply and the inverter for merely assisting soft-switching of the inverter without participating in real DC power transmission and power conversion, malfunction and failure of the tank circuit will not affect the functional operation of the inverter. Thus a highly reliable inverter system is expected. A 100 kW (150 kVA) continuous power AQRDCT inverter has been built, fully tested, and put into a 22-foot electric bus for traction drive applications. Tested results showed good efficiency, reduced EMI, and reliable operation. This paper describes the operating principle and control and reports the test results.
Transformer-fault diagnosis by integrating field data and standard codes with training enhancible adaptive probabilistic network

A transformer-fault diagnosis system (TFDS) using a probabilistic neural network (PNN) and IEC/Cigre standard codes is proposed. Many artificial neural networks (ANNs) have been proposed before, however, the slow repeated iterative process and poor adaptation capability for structural data restrains the ANN applications. An effective and flexible PNN could overcome these drawbacks. In this paper, a PNN analyses the transformer's dissolved gas content to identify faults, while using the gas ratios of the oil and cellulosic decomposition to create training examples. Retraining can be done by adding new examples and new hidden nodes for easy adaptation without doing any computed iteration. The commonly used Excel was integrated to provide a convenient man-machine interface. Computer simulations were conducted with diagnostic gas records, to show the effectiveness of the proposed system.
PERFORMANCE ANALYSIS OF 2D CONVERTER BY COMBINING SR & KY CONVERTERS

Most of the portable equipments use battery as power source. The increasing use of low voltage portable devices and growing requirements of functionalities embedded into such devices. Thus an efficient power management technique is needed for longer battery life for them. Highly variable nature of batteries systems often require supply voltages to be both higher and lower than the battery. This is most efficiently generated by a buck-boost switching converter. But here the converter efficiency is decreased since the power loss occurs in the storage devices. Step by step, process of designing, feedback control and simulation of a novel voltage-buck boost converter, combining KY and synchronous Rectifier buck converter for battery power applications. Unlike the traditional buck–boost converter, this converter has the positive output voltage and system is stable, different from the negative output voltage and low stable of the traditional inverting buck–boost converters. Since such a converter operates in continuous conduction mode. Also it possesses the non-pulsating output current, thereby not only decreasing the current stress on the output capacitor but also reducing the output voltage ripple. Both the KY converter and the synchronous buck converter, combined into a positive buck– boost converter, uses the same power switches. Here it makes the circuit to be compact and the corresponding cost to be down. Voltage conversion ratio is 2D,so it is also called 2D converter. Index Terms- buck-boost converter, PI control, KY converter, synchronously rectified (SR) buck converter

Treatment Resistant Alcohol Use Disorder

ABSTRACT Despite existing interventions that have shown some promise for people with alcohol use disorder (AUD), there is a sizable number of patients that fail to respond to or complete treatment. In the current study, we analyzed data from the Treatment Episode Data Set (TEDS) to create profiles that indicate who may be more likely to resist treatment-as-usual. For the analysis, chi-square and logistic regression were used to associate personal characteristics with being at high and low risk of treatment resistance. Characteristics that put someone at higher risk of resisting treatment-as-usual include being unemployed, homelessness (or a dependent living arrangement), using daily, being male, and co-occurring mental and substance abuse disorders. The results suggest that general demographic information at patients’ admission can be used to identify population groups where conventional strategies for standard AUD treatment may be insufficient. As such, the findings can help to inform, shape, and personalize treatment, leading to successful outcomes for the subgroup of individuals who will not benefit from typical AUD interventions.
