Testing and performance analysis of 1KW locally made grid tie photovoltaic inverter using thin film solar panel
Venue: 2016 4th International Conference on the Development in the in Renewable Energy Technology (ICDRET)

It is mandatory in Bangladesh to install solar panel on the rooftop of a newly build apartment or factory in order to get utility connection from the service provider. The most cost effective and efficient way of producing energy using solar panel is to connect the panels to the utility grid through Grid Tie Inverter (GTI) GTI is one of the most important components of the grid tie solar system that basically converts dc power from the solar panel into ac power; synchronizing the phase, frequency and voltage of the utility grid. Presently almost all the GTI uses in Bangladesh are imported from other countries and it is very expensive. A low cost 1 kW grid tie inverter for solar PV module has been designed and implemented in the power electronic laboratory of the university. Physical demonstration was made by installing 1 kW Thin Film PV modules on the rooftop of the university building and setting up the inverter and others measuring equipments inside the lab. Based on the experimental data, the performance of the system is analyzed and presented in this paper.
Large Scale Location Recognition and the Geometric Burstiness Problem
Venue: 2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)

Visual location recognition is the task of determining the place depicted in a query image from a given database of geo tagged images. Location recognition is often cast as an image retrieval problem and recent research has almost exclusively focused on improving the chance that a relevant database image is ranked high enough after retrieval. The implicit assumption is that the number of inliers found by spatial verification can be used to distinguish between a related and an unrelated database photo with high precision. In this paper, we show that this assumption does not hold for large datasets due to the appearance of geometric bursts, i.e. sets of visual elements appearing in similar geometric configurations in unrelated database photos. We propose algorithms for detecting and handling geometric bursts. Although conceptually simple, using the proposed weighting schemes dramatically improves the recall that can be achieved when high precision is required compared to the standard re ranking based on the inlier count. Our approach is easy to implement and can easily be integrated into existing location recognition systems.
Multiplicative Error State Kalman Filter vs Nonlinear Complimentary Filter for a High Performance Aircraft Attitude Estimation

Modern control law designs increasingly use aircraft attitude information to improve aircraft manoeuverability. Attitude information allows for gravity term compensations in the longitudinal as well as lateral directional control laws of a typical fighter aircraft. Methodologies and comparisons of multiplicative error state Kalman filter (MEKF) and nonlinear complimentary filter for estimation of attitudes of a high performance aircraft using its onboard autonomous sensors is presented. Shows a problem in pitch angle estimation beyond 80 deg in the MEKF and a solution is proposed for the same for the first time. Also presents novel aiding sensor modelling for the implementation of attitude heading reference system for this class of aircraft for the first time. The filter formulations are evaluated using full range manuoevering real flight test data.
Remote Sensing Technologies for Enhancing Forest Inventories: A Review

Forest inventory and management requirements are changing rapidly in the context of an increasingly complex set of economic, environmental, and social policy objectives. Advanced remote sensing technologies provide data to assist in addressing these escalating information needs and to support the subsequent development and parameterization of models for an even broader range of information needs. This special issue contains papers that use a variety of remote sensing technologies to derive forest inventory or inventory related information. Herein, we review the potential of 4 advanced remote sensing technologies, which we posit as having the greatest potential to influence forest inventories designed to characterize forest resource information for strategic, tactical, and operational planning: airborne laser scanning (ALS) terrestrial laser scanning (TLS) digital aerial photogrammetry (DAP) and high spatial resolution (HSR)/very high spatial resolution (VHSR) satellite optical imagery. ALS, in particular, has proven to be a transformative technology, offering forest inventories the required spatial detail and accuracy across large areas and a diverse range of forest types. The coupling of DAP with ALS technologies will likely have the greatest impact on forest inventory practices in the next decade, providing capacity for a broader suite of attributes, as well as for monitoring growth over time.

Venue: Critical reviews in food science and nutrition

Extrusion of foods is an emerging technology for the food industries to process and market a large number of products of varying size, shape, texture, and taste. Extrusion cooking technology has led to production of wide variety of products like pasta, breakfast cereals, bread crumbs, biscuits, crackers, croutons, baby foods, snack foods, confectionery items, chewing gum, texturized vegetable protein (TVP) modified starch, pet foods, dried soups, dry beverage mixes etc. The functional properties of extruded foods plays an important role for their acceptability which include water absorption, water solubility, oil absorption indexes, expansion index, bulk density and viscosity of the dough. The aim of this review is to give the detailed outlines about the potential of extrusion technology in development of different types of products and the role of extrusion operating conditions and their effect on product development resulting in quality changes i.e physical, chemical, and nutritional, experienced during the extrusion process.
Calcium and Potassium Fertilization May Enhance Potato Tuber Yield and Quality Nesreen Ahmed Sabry Helal and Slama A. AbdElhady

Field experiment was carried out in a private farm in Delta Nile region, Menofia Governorate, Egypt, during 2013 and 2014 seasons, in order to investigate the effect of calcium and potassium application on vegetative growth, and yield quality of Potato (Solanum tuberosum. L) cv. Spounta. The calcium nitrate was used at rates of 0, 10, 20 kg as net calcium per feddan. The potassium nutrient was added in the form of potassium sulfate (K2SO4) at rate of 0, 25, 50, 75 kg as net potassium per feddan Data collected were stem length, number of branches, Plant dry weight, chlorophyll content, and tuber yield. Average tuber weight, tuber specific gravity, percent of infected tubers with internal brown spots and plant chemical content were also determined. Results indicated that, the level of 50 and 75 net K kg per feddan improved plant growth and chemical content significantly of potato in both seasons. The same results were obtained with 10, 20 net Ca kg per feddan. Concerning, the effect of interaction between calcium and potassium treatment, the results revealed that 20 net calcium kg/faddan with 75 net potassium kg /feddan were the best treatment for vegetative growth and yield of potato plants. It was concluded that calcium and potassium fertilization may enhance potato tuber yield and quality.
Analytical model for thermal boundary conductance and equilibrium thermal accommodation coefficient at solid/gas interfaces.
Venue: The Journal of chemical physics

We develop an analytical model for the thermal boundary conductance between a solid and a gas. By considering the thermal fluxes in the solid and the gas, we describe the transmission of energy across the solid/gas interface with diffuse mismatch theory. From the predicted thermal boundary conductances across solid/gas interfaces, the equilibrium thermal accommodation coefficient is determined and compared to predictions from molecular dynamics simulations on the model solid gas systems. We show that our model is applicable for modeling the thermal accommodation of gases on solid surfaces at non cryogenic temperatures and relatively strong solid gas interactions (e(sf) k(B)T)
Method for measuring thermal accommodation coefficients of gases on thin film surfaces using a MEMS sensor structure

A method for measuring the thermal accommodation coefficient a for surface /gas interfaces is presented. It allows the determination of a for thin films produced by a variety of deposition technologies, such as chemical vapor deposition, physical vapor deposition, and atomic layer deposition (ALD) The setup is based on two microelectromechanical systems (MEMS) Pirani sensors facing each other in a defined positioning. Because these MEMS sensors show a very high sensitivity in their individual molecular flow regimes, it is possible to measure the accommodation coefficients of gases without the disturbing influence of the transition regime. This paper presents the analytical background and the actual measurement principle. The results for air and nitrogen molecules on sputtered Au and Pt surfaces are presented.
Gas flow towards an adsorbing planar wall subject to partial gas surface thermal accommodation

The steady half space single gas flow driven by an adsorbing planar wall is investigated based on the solution of the BGK kinetic model. The mass and heat transfer between the gas and the plate are characterized by the sticking and thermal accommodation coefficients, the surface temperature and the far upstream velocity and temperature. The work is focused on the influence of partial thermal gas surface interaction on all flow quantities including the sticking coefficient. It has been found that as the gas thermal accommodation on the surface is reduced, for prescribed adsorbing flux and temperature difference, the sticking coefficient must be increased to sustain the prescribed flux or otherwise for the same sticking coefficient the adsorbing flux is reduced. This behavior is enhanced as the difference, between the surface and the far upstream temperatures, is increased. Overall, the effect of the thermal accommodation coefficient is significant in all flow quantities and must be accordingly taken into consideration. The present theoretical/computational investigation of partial thermal accommodation effect may provide a more clear interpretation of measurements of sticking coefficients, and conversely, improve performance calculations for cryopumps.
Thermal accommodation at cold Ar atoms collisions with small Fe clusters at different temperatures

Thermal accommodation coefficients at collisions of solitary argon atoms at room temperature with iron clusters at temperatures 200 2500 K are calculated. Molecular dynamics method is applied. Finnis Sinclair potential is used to describe interaction between iron atoms in clusters. The incident atom interacts with a cluster through the Buckingham potential. The number of incident atom trajectories is from 10000 to 100000. Initial velocities of incident atoms obey the Maxwell distribution. Thermal accommodation coefficient is calculated for 2 sizes of cluster, 9 and 27 atoms.
OpenPNM: A Pore Network Modeling Package
Venue: Computing in Science Engineering

Pore network modeling is a widely used technique for simulating multiphase transport in porous materials, but there are very few software options available. This work outlines the OpenPNM package that was jointly developed by several porous media research groups to help address this gap. OpenPNM is written in Python using NumPy and SciPy for most mathematical operations, thus combining Python's ease of use with the performance necessary to perform large simulations. The package assists the user with managing and interacting with all the topological, geometrical, and thermophysical data. It also includes a suite of commonly used algorithms for simulating percolation and performing transport calculations on pore networks. Most importantly, it was designed to be highly flexible to suit any application and be easily customized to include user specified pore scale physics models. The framework is fast, powerful, and concise. An illustrative example is included that determines the effective diffusivity through a partially water saturated porous material with just 29 lines of code.
Dynamic modeling based on a temporal causal network modeling approach
Venue: BICA 2016

This paper presents a dynamic modeling approach that enables to design complex high level conceptual representations of models in the form of causal temporal networks, which can be automatically transformed into executable numerical model representations. Dedicated software is available to support designing models in a graphical manner, and automatically transforming them into an executable format and performing simulation experiments. The temporal causal network modeling format used makes it easy to take into account theories and findings about complex brain processes known from Cognitive, Affective and Social Neuroscience, which, for example, often involve dynamics based on interrelating cycles. This enables to address complex phenomena such as the integration of emotions within all kinds of cognitive processes, and of internal simulation and mirroring of mental processes of others. In this paper also the applicability has been discussed in general terms.
Contribution of Underlying Connective Tissue Cells to Taste Buds in Mouse Tongue and Soft Palate
Venue: PloS one

Taste buds, the sensory organs for taste, have been described as arising solely from the surrounding epithelium, which is in distinction from other sensory receptors that are known to originate from neural precursors, i.e. neural ectoderm that includes neural crest (NC) Our previous study suggested a potential contribution of NC derived cells to early immature fungiform taste buds in late embryonic (E18.5) and young postnatal (P1 10) mice. In the present study we demonstrated the contribution of the underlying connective tissue (CT) to mature taste buds in mouse tongue and soft palate. Three independent mouse models were used for fate mapping of NC and NC derived connective tissue cells: (1) P0 Cre/R26 tdTomato (RFP) to label NC, NC derived Schwann cells and derivatives; (2) Dermo1 Cre/RFP to label mesenchymal cells and derivatives; and (3) Vimentin CreER/mGFP to label Vimentin expressing CT cells and derivatives upon tamoxifen treatment. Both P0 Cre/RFP and Dermo1 Cre/RFP labeled cells were abundant in mature taste buds in lingual taste papillae and soft palate, but not in the surrounding epithelial cells. Concurrently, labeled cells were extensively distributed in the underlying CT. RFP signals were seen in the majority of taste buds and all three types (I, II, III) of differentiated taste bud cells, with the neuronal like type III cells labeled at a greater proportion. Further, Vimentin CreER labeled cells were found in the taste buds of 3 month old mice whereas Vimentin immunoreactivity was only seen in the CT. Taken together, our data demonstrate a previously unrecognized origin of taste bud cells from the underlying CT, a conceptually new finding in our knowledge of taste bud cell derivation, i.e. from both the surrounding epithelium and the underlying CT that is primarily derived from NC.
Labeling and analysis of chicken taste buds using molecular markers in oral epithelial sheets
Venue: Scientific reports

In chickens, the sensory organs for taste are the taste buds in the oral cavity, of which there are ~240 360 in total number as estimated by scanning electron microscopy (SEM) There is not an easy way to visualize all taste buds in chickens. Here, we report a highly efficient method for labeling chicken taste buds in oral epithelial sheets using the molecular markers Vimentin and a Gustducin. Immediate tissue fixation following incubation with sub epithelially injected proteases enabled us to peel off whole epithelial sheets, leaving the shape and integrity of the tissue intact. In the peeled epithelial sheets, taste buds labeled with antibodies against Vimentin and a Gustducin were easily identified and counted under a light microscope and many more taste buds, patterned in rosette like clusters, were found than previously reported with SEM. Broiler type, female line males have more taste buds than other groups and continue to increase the number of taste buds over stages after hatch. In addition to ovoid shaped taste buds, big tube shaped taste buds were observed in the chicken using 2 photon microscopy. Our protocol for labeling taste buds with molecular markers will factilitate future mechanistic studies on the development of chicken taste buds in association with their feeding behaviors.
Insulin Like Growth Factors Are Expressed in the Taste System, but Do Not Maintain Adult Taste Buds
Venue: PloS one

Growth factors regulate cell growth and differentiation in many tissues. In the taste system, as yet unknown growth factors are produced by neurons to maintain taste buds. A number of growth factor receptors are expressed at greater levels in taste buds than in the surrounding epithelium and may be receptors for candidate factors involved in taste bud maintenance. We determined that the ligands of eight of these receptors were expressed in the E14.5 geniculate ganglion and that four of these ligands were expressed in the adult geniculate ganglion. Of these, the insulin like growth factors (IGF1, IGF2) were expressed in the ganglion and their receptor, insulin like growth factor receptor 1 (IGF1R) were expressed at the highest levels in taste buds. To determine whether IGF1R regulates taste bud number or structure, we conditionally eliminated IGF1R from the lingual epithelium of mice using the keratin 14 (K14) promoter (K14 Cre::Igf1rlox/lox) While K14 Cre::Igf1rlox/lox mice had significantly fewer taste buds at P30 compared with control mice (Igf1rlox/lox) this difference was not observed by P80. IGF1R removal did not affect taste bud size or cell number, and the number of phospholipase C b2 (PLCb2) and carbonic anhydrase 4 (Car4) positive taste receptor cells did not differ between genotypes. Taste buds at the back of the tongue fungiform taste field were larger and contained more cells than those at the tongue tip, and these differences were diminished in K14 Cre::Igf1rlox/lox mice. The epithelium was thicker at the back versus the tip of the tongue, and this difference was also attenuated in K14 Cre::Igf1rlox/lox mice. We conclude that, although IGFs are expressed at high levels in the taste system, they likely play little or no role in maintaining adult taste bud structure. IGFs have a potential role in establishing the initial number of taste buds, and there may be limits on epithelial thickness in the absence of IGF1R signaling.
Distribution of a Gustducin and Vimentin in premature and mature taste buds in chickens.
Venue: Biochemical and biophysical research communications

The sensory organs for taste in chickens (Gallus sp. are taste buds in the oral epithelium of the palate, base of the oral cavity, and posterior tongue. Although there is not a pan taste cell marker that labels all chicken taste bud cells, a Gustducin and Vimentin each label a subpopulation of taste bud cells. In the present study, we used both a Gustducin and Vimentin to further characterize chicken taste buds at the embryonic and post hatching stages (E17 P5) We found that both a Gustducin and Vimentin label distinct and overlapping populations of, but not all, taste bud cells. A Gustducin immunosignals were observed as early as E18 and were consistently distributed in early and mature taste buds in embryos and hatchlings. Vimentin immunoreactivity was initially sparse at the embryonic stages then became apparent in taste buds after hatch. In hatchlings, a Gustducin and Vimentin immunosignals largely co localized in taste buds. A small subset of taste bud cells were labeled by either a Gustducin or Vimentin or were not labeled. Importantly, each of the markers was observed in all of the examined taste buds. Our data suggest that the early onset of a Gustducin in taste buds might be important for enabling chickens to respond to taste stimuli immediately after hatch and that distinctive population of taste bud cells that are labeled by different molecular markers might represent different cell types or different phases of taste bud cells. Additionally, a Gustducin and Vimentin can potentially be used as molecular markers of all chicken taste buds in whole mount tissue.
Effects of a Universal Positive Classroom Behavior Program on Student Learning.

The purpose of this study was to examine the impact of a universal program to promote positive classroom behavior on students' approaches to learning and early academic skills. Second grade classrooms (N 39) were randomly assigned to treatment and business as usual control conditions. Teachers in intervention classrooms implemented the Social Skills Improvement System Classwide Intervention Program (SSIS CIP) over a 12 week period. Participating students' (N 494) engagement, motivation, and academic skills were assessed before and after treatment implementation. Results indicated that students with lower levels of engagement and motivation at pretest experienced significant improvement in these areas after exposure to the SSIS CIP. Although no significant differences were observed in reading, students receiving supplemental instructional services demonstrated greater gains in mathematics than did their peers in the control condition.
The Effects of Classroom Interventions on Off Task and Disruptive Classroom Behavior in Children with Symptoms of Attention Deficit/Hyperactivity Disorder: A Meta Analytic Review
Venue: PloS one

Children with attention deficit/hyperactivity disorder (ADHD) often exhibit problem behavior in class, which teachers often struggle to manage due to a lack of knowledge and skills to use classroom management strategies. The aim of this meta analytic review was to determine the effectiveness of several types of classroom interventions (antecedent based, consequence based, self regulation, combined) that can be applied by teachers in order to decrease off task and disruptive classroom behavior in children with symptoms of ADHD. A second aim was to identify potential moderators (classroom setting, type of measure, students' age, gender, intelligence, and medication use) Finally, it was qualitatively explored whether the identified classroom interventions also directly or indirectly affected behavioral and academic outcomes of classmates. Separate meta analyses were performed on standardized mean differences (SMDs) for 24 within subjects design (WSD) and 76 single subject design (SSD) studies. Results showed that classroom interventions reduce off task and disruptive classroom behavior in children with symptoms of ADHD (WSDs: MSMD 0.92; SSDs: MSMD 3.08) with largest effects for consequence based (WSDs: MSMD 1.82) and self regulation interventions (SSDs: MSMD 3.61) Larger effects were obtained in general education classrooms than in other classroom settings. No reliable conclusions could be formulated about moderating effects of type of measure and students' age, gender, intelligence, and medication use, mainly because of power problems. Finally, classroom interventions appeared to also benefit classmates' behavioral and academic outcomes.
