WIND ENERGY CONVERSION: THE POTENTIAL OF A NOVEL DUCTED TURBINE FOR RESIDENTIAL AND COMMERCIAL APPLICATIONS

A novel ducted turbine, referred to as a Wind Tower, for capturing wind power in either residential or commercial scale applications is studied theoretically and experimentally. A mathematical model is developed to predict the flow behavior inside the tower and a velocity coefficient is defined to correct the results at different test conditions. A wind tower prototype, including a four-quadrant-peak wind-catcher rooftop, a tower, a nozzle, and a turbine, is designed and fabricated. The captured wind power values from the mathematical model and the preliminary experimental tests are compared. While the mathematical model provides a good estimation of the output power in some cases, more precise experimental tests and simulation techniques are required to improve the mathematical model in some other cases. Significant changes in the output wind speed due to pressure differences created by the surrounding environment, the tower height, and the number of nozzles are observed. The advantages of being maintenance free, reliable, and sustainable, together with its special design that eliminates bird/bat mortality make the Wind Tower a promising solution for residential, commercial, and even off-grid applications.Copyright © 2013 by ASME
C V ] 19 F eb 2 01 5 Pairwise Constraint Propagation : A Survey

As one of the most important types of (weaker) supervised inf ormation in machine learning and pattern recognition, pairwise constraint, which speci fies whether a pair of data points occur together, has recently received significant attentio n, especially the problem of pairwise constraint propagation. At least two reasons account for th is trend: the first is that compared to the data label, pairwise constraints are more general and e sily to collect, and the second is that since the available pairwise constraints are usuall y limited, the constraint propagation problem is thus important. This paper provides an up-to-date critical survey of pairwi se constraint propagation research. There are two underlying motivations for us to write this survey paper: the first is to provide an up-to-date review of the existing literature, an d the second is to o ffer some insights into the studies of pairwise constraint propagation. To pro vide a comprehensive survey, we not only categorize existing propagation techniques but al so present detailed descriptions of representative methods within each category.
Stability-Indicating UHPLC Method for the Determination of Desvenlafaxine: Application to Degradation Kinetics

This study was aimed to investigate the degradation behavior and physicochemical stability of desvenlafaxine using reversed-phase ultra-high-performance liquid chromatography (RP-UHPLC) system. The chromatogram was developed on Eclipse XDB-C8 column (150 x 4.6 mm, 5μm). The eluents were monitored through a photo diode array plus (PDA+) detector at 210 nm using an isocratic method with a flow rate of 1.5 ml/min. Mobile phase composition was 30:70 v/v mixture of 0.1 % trifluoroacetic acid (TFA) in water and methanol. Forced degradation studies were performed on drug substance of desvenlafaxine as per International Conference on Harmonization (ICH) prescribed stressed conditions (Q1A(R2) and Q1B) using hydrolytic (acidic, basic, and neutral), oxidative and photolytic methods. The drug substance was found highly labile to acidic (0.5 N hydrochloric acid, 18.65 % degradation in 2 hours at 70°C), basic (1.0 N sodium hydroxide, 11.01 % degradation in 12 hours at 70°C) and oxidative (3 % hydrogen peroxide, 17.05 % degradation in 2 hours at 50°C) stressed conditions, but a great resistance was observed towards dry heat (maximum degradation 0.27 % in 10 days from ambient to higher temperature, 80°C), moist heat (maximum degradation 0.25 % in 2 hours at 80°C and 75 % relative humidity) as well as in photolytic degradation (maximum degradation 0.23 % in 10 days at UV light of 315 - 400 nm). A pseudo-first order kinetic was followed in acidic, basic and peroxide degradation methods which paved a way to calculate the half-life of the drug substance desvenlafaxine under ICH mentioned stressed conditions. The results were also statistically analyzed and the % RSD values were compared with recommended guidelines. Dhaka Univ. J. Pharm. Sci. 20(2): 167-176, 2021 (December)
The Bangladeshi Rights and Protection of Persons With Disability Act of 2013: A Policy Analysis

The government of Bangladesh enacted the Rights and Protection of Persons with Disability Act of 2013 (the Act) in line with the United Nations Convention on the Rights of Persons with Disabilities. This article sheds light on the Act with particular emphasis on (a) support offered to children with disabilities (CWDs) and their families to address their needs; and (b) the extent to which the Act is in line with the international disability policy analysis framework. We compared the Act with the 18 core concepts of disability policy developed by Turnbull et al. (2001). The results affirm the government’s effort toward Sustainable Development Goals in providing support to CWDs and their families. They indicate a high degree of congruency of the Act with the core concepts. The findings also highlight the need to embrace the concepts of autonomy, confidentiality, and family-centeredness in great detail in any policy initiatives pertaining to CWDs. Furthermore, the finding shows that collaboration and coordination among ministries are imperative to achieve the goal of policies related to disability. In addition, the results highlight the need for more budgetary allocation and robust monitoring systems to track the progress of policy initiatives. As policy implementation is affected by changes in global contexts such as the coronavirus disease 2019 pandemic, policymakers in Bangladesh and other low- and middle-income countries should ensure that emergency responses are disability-inclusive and appropriate for CWDs. To ensure a disability-inclusive response, it is critical to engage individuals with disabilities and their families in meaningful consultations to identify their needs.
Nonlinear dynamics of ship oscillations

The stability of a ship's motions is crucial for the safety of its crew, its cargo, and the environment. To prevent losses due to unstable motions, particularly in high seas, a better understanding of ship stability is necessary. We analyze the stability of ship motions using a hydrodynamic model accounting for all the rigid body motions of a ship, as well as memory effects in the fluid. The analysis of a particular ship shows that ship's dynamics depend strongly on the nonlinearities of the ship-fluid-system. Before the ship capsizes we notice a bifurcation when wave heights increase. A path following method is employed to determine in a systematic manner the stability limits. The application for a simplified system shows the importance of the nonlinearities of the mathematical model.
S-parameter based technique for simultaneous switching noise analysis in electronic packages

A method based on S-parameters is developed for the analysis of simultaneous switching noise (SSN) in electronic packages. A two-port Z matrix of the package pin/trace, and the coupling between the pins/traces are modeled by analytical equations. SSN is analyzed as a function of the number of switching drivers and switching time. Frequency domain measurements are performed to demonstrate the accuracy of the model. The modeling methodology is applied to both leaded and area array packages.
1 INFLECTION VS . DERIVATION IN A DISTRIBUTIONAL VECTOR SPACE

This paper is an attempt to assess empirically whether, as often stated in the literature, inflection is “semantically more regular” than derivation. We reformulate the observation in terms of the stability of syntactic and semantic contrasts within a morphological relation: inflectional contrasts are hypothesized to be more stable than derivational contrasts. We then propose an operational definition of contrasts between words as offset vectors in a distributional vector space of the kind familiar from distributional semantics. In the empirical part of the paper, we show that French data does validate the hypothesis for all pairings of an inflectional and a derivational relation that we were able to investigate.
Iterative Development of a Mobile Phone App to Support Community Health Volunteers During Cervical Cancer Screening in Western Kenya: Qualitative Study

Background To achieve the World Health Organization targets for cervical cancer elimination, low- and middle-income countries will need to develop innovative strategies to provide human papillomavirus (HPV)–based screening at a population level. Although mobile health (mHealth) interventions may help realize these goals by filling gaps in electronic specimen tracking and patient education, effective implementation of mHealth interventions is dependent upon context-specific development that is acceptable and usable by the target population. Detailed feedback should be gathered at the design and development stages to yield final products that reflect the needs, desires, and capabilities of target users. Objective The aim of this study is to develop an mHealth app (mSaada) to support HPV-based screening in partnership with community health volunteers (CHVs) and program planners in western Kenya. Methods A team of student programmers developed a prototype to meet previously identified gaps in screening: patient education, protocol support, data capture, and specimen tracking. The prototype was iteratively developed through 2 waves of in-person working sessions with quantitative (survey) and qualitative (in-depth interview) feedback. Research staff engaged key stakeholders from both urban and rural locations and with varying levels of experience in delivering screening services. During the sessions, participants completed simulation exercises and role-play activities to become familiar with the platform. Once feedback was gathered and synthesized after each wave of in-person data collection, developers implemented changes to improve mSaada functionality. Results A total of 18 CHVs and clinicians participated in the in-person sessions. Participants found mSaada useful, easy to use, and would meet the needs of CHVs to provide HPV-based cervical cancer screening (electronic data capture, client education resources, and specimen tracking). They provided key feedback to enhance user experience, workflow, and sustainability. Key changes included altering the appearance of the wireframes, adding translation in additional local languages, changing potentially insensitive figures, alphabetizing lengthy dropdown menus, adding clinically relevant logic checks when entering data, and incorporating the ability to make real time edits to client records. They also made recommendations for additional features that might enhance mSaada’s impact at the facility and health system levels, specifically the inclusion of a report-generating tool consistent with the Ministry of Health standards. Conclusions Using a process of iterative feedback with key stakeholders and rapid response from developers, we have developed a mobile app ready for pilot testing in HPV-based screening programs led by CHVs.
Crab-Eating Mongoose Herpestes urva: Occurrence and its Activity in Mid-Hills of Nepal

Small carnivores are able to adapt to patchy forests and human dominated landscape in proximity to water sources. Small carnivore’s population is declining due to anthropogenic effects, and in most of the areas, their occurrence is little known. We aimed to identify the spatial occurrence of crab-eating mongoose, the factors affecting the occurrence of species and coexistence with other species using camera trap. The crab-eating mongoose mostly preferred the shrub-land habitat (65%) and followed by agriculture land, forest and grassland. Almost all preferred habitats were near to water sources. The occurrence of crab-eating mongoose was influenced by human disturbances. Their occurrences were decreased with increasing disturbances. In addition, the crab-eating mongoose’s occurrence was also decreased with increasing distance to water sources. The movement activities of crab-eating mongoose were varied according to time period (F = 6; df = 14; p < 0.013), and was mostly active at day to mid-night (16.00 to 12.00 hours) and mid-night to early morning (12.00 to 8.00 hours). The crab-eating mongoose co-exists with other carnivores including Leopard, Jungle cat, Masked-palm civet, Small Indian mongoose, Leopard cat, Yellow-throated martin, and Large Indian civet. In addition, its occurrence was affected by human interference. The data available from this study can be used to develop site/species-specific conservation plans that aid stewardship for biodiversity conservation.
Design, implementation, and experimental results of bi-directional full-bridge DC/DC converter with unified soft-switching scheme and soft-starting capability

The PWM control, design and implementation issues of the bi-directional dual full-bridge DC/DC converter with a unified soft-switching scheme and soft-start capability, which was proposed in a companion paper, are presented in this part of the two-paper sequel. Test results on a 5 kW prototype converter, which is connected between a 12 V battery and a high voltage bus, and targeted for alternative energy applications, validate the secure operation, high reliability and superior efficiency of the proposed converter topology.
JIT manufacturing: The evolution to animplementation model founded in current practice

The authors identify the circumstances surrounding the early use of JIT manufacturing, its evolution, and the subsequent spread of its use across the industrialized world. Current production engineering practice is reviewed and the use of particular waste elimination techniques are examined. Definitions proposed in the literature are discussed and shortcomings identified. On the basis of this analysis a model of JIT manufacturing reflecting evolution and current practice is developed. It is based on the elimination of waste, constructed from specific ranges of support levers (managerial actions), waste elimination techniques, and performance measures, and set in a specific manufacturing context (the combination of people, machines, materials, processes, products, and managerial policies). Finally, the use of the model in JIT implementation is discussed as part of a structured engineering process to guide and formalize JIT implementation.

EFFECT OF INTEGRATED APPLICATION OF INORGANIC AND ORGANIC SOURCES ON YIELD AND MICRONUTRIENT UPTAKE BY PEARL-MILLET

An experiment to find out the relative performance of two sources of organic and NPK is in progress in alluvial soils (Inceptisol) of College of Agriculture Gwalior, with nine treatments & 3 replications is in progress since 2004 in randomized block design. Data presented has been obtained from the crop grown during Kharif 2014-15. The results indicate that integrated use of 50% of optimum NPK + 50% vermicompost produced significantly higher grain yield over remaining treatments except optimum NPK. Two sources of organics resulted in lower yield, however maximum total uptake of Cu, Fe, Zn, Mn was recorded in 100% NPK. Maximum net profit and B:C ratio were recorded by the use of optimum NPK (Rs.31918/and 2.44) respectively.
REPAIRS IN MANDARIN CONVERSATION

This paper reports statistical data on the use of syntactically and prosodically defined variables in speech repairs in Mandarin Chinese. These variables include structural types of Chinese repairs, their part of speech distribution and their syllabic characteristics regarding the retracing distance. With respect to the prosodic features of Chinese repairs, results on articulation rate of the overall data and the repair data are presented as well as a durational analysis of the reparandum and the alteration of frequent words. Pitch value, amplitude and duration are analyzed on the beginning positions of the to-be-corrected, the corrected, the to-be-repeated and the repeated words. Among the findings are a number of significant results in terms of the syntactic and prosodic variables within the re-initiation process of Chinese repairs and their relationship to intonation units.
Identification of Gas-Liquid Flow Regimes From a Space-Frequency Representation by Use of an Impedance Probe and a Neural Network

The identification of two-phase flow patterns has been widely studied, and the diagnostic procedures are traditionally based on statistical or spectral signal analysis, while the spatial information related with the geometrical topology of the phase distribution in the pipe is never taken into account. The aim of this study is to demonstrate how the exploitation of both spectral and spatial information leads to an unambiguous identification of the flow patterns. Experiments are performed on a 30 meters long horizontal air-water loop. By simultaneously analyzing the power spectral density of the signals delivered by a multi-electrode impedance sensor, we obtain a space-frequency representation which exhibits particular features of the different flow regimes. They can be characterized by a set of 3 scalar parameters, quantifying respectively the localization in space, in frequency and the shape of the spectral content. The final demonstration of this space-frequency characterization is provided by the use of a multi-layer neural network, trained on a 80 tests database. This net exhibits a successful identification rate above 80% when used in blind real-time tests.Copyright © 2002 by ASME
Mechanics of nanotubes oscillating in carbon nanotube bundles

Carbon nanotubes are nanostructures that promise much in the area of constructing nanoscale devices due to their enhanced mechanical, electrical and thermal properties. In this paper, we examine a gigahertz oscillator that comprises a carbon nanotube oscillating in a uniform concentric ring or bundle of carbon nanotubes. A number of existing results for nanotube oscillators are employed to analyse the design considerations of optimizing such a device, and significant new results are also derived. These include a new analytical expression for the interaction per unit length of two parallel carbon nanotubes involving the Appell hypergeometric functions. This expression is employed to precisely determine the relationship between the bundle radius and the radii of the nanotubes forming the bundle. Furthermore, several pragmatic approximations are also given, including the relationships between the bundle radius and the constituent nanotube radius and the oscillating tube radius and the bundle nanotube radius. We also present a simplified analysis of the force and energy for a nanotube oscillating in a nanotube bundle leading to an expression for the oscillating frequency and the maximum oscillating frequency, including constraints on configurations under which this maximum is possible.
Website Fingerprinting in the Data Plane

The Internet was not designed with security and privacy in mind. Over the last couple of years, speciﬁc protocols and protocol extensions have been introduced to patch the Internet architecture’s security and privacy weaknesses. To name a few, HTTPS [14], encrypted DNS (DNS over TLS [25] or DNS over HTTPS [20]), and encrypted SNI [15] (an extension to TLS protocol) focus on making the Internet a more private place by encrypting the sensitive parts of the packets. The goal of all these privacy-preserving protocols and their extensions is to hide the metadata that is otherwise visible to the entities monitoring the Internet traﬃc. However the IP addresses on the packet headers are still readable for everyone and can be used to get information about the accessed domains in a reversed approach. As a ﬁrst countermeasure Content Delivery Networks [19] impede eavesdropping on IP addresses because they map several websites to the same IP address, so a monitoring entity can no longer tell directly from the IP which page is accessed. However, we can show that the comparison with previously stored page load ﬁngerprints makes it possible to identify domains with a high accuracy. In this thesis, we were able to create a design that detects domains in less than 5 seconds after the opening of a new session with a correct detection rate of 75.1% when multiple domains have the same primary IP address and 92.4% when a single domain maps to one primary IP address. For the thesis, we generate a data set that contains the page load ﬁngerprints of roughly 50’000 domains. We use it together with a data plane pipeline design of a switch, which is applied to ﬁlter traﬃc speciﬁcally and reduces the packet load that needs to be analysed at an early stage. To compare ﬁngerprints and determine accessed websites we develop an analysing script that works in the control plane. A Barefoot Toﬁno TM Model works as our target to test the implemented design.
Chapter 5 Implications of the number semantics of NP objects for the interpretation of imperfective verbs in Polish

Languages differ in the range of readings of imperfective aspect but its single ongoing and plural event readings are cross-linguistically licensed. In this study we focus on the role of the number of NP objects on the disambiguation of Polish imperfective verbs. The crucial observation is that a singular object may block whereas a plural NP object creates a strong preference for the plural event reading of imperfective verbs. However, in the right context, the plural event reading of imperfective verbs is also available with singular NP objects. In order to account for these observations, we combine underspecification and number approaches to imperfective aspect and we propose that imperfective is underspecified for number and this information is specified via a coercion template mainly on the basis of the number semantics of nominal objects of imperfective verbs.
