Visual Enhancement Method for Intelligent Vehicle Based on Brightness Guide Filtering Algorithm

In order to improve the low visibility and poor contrast of video, in this study, we propose a haze video enhancement algorithm based on guide filtering method. In the paper, firstly, we simplified the atmospheric attenuation model. Then, the current concentration of haze is estimated based on dark channel priori theory. After that, a guide filter of brightness channel was used to obtain current haze coverage. Videos are recovered based on the results of estimation of haze concentration and coverage. To improve the efficiency of the algorithm, highly time-consuming stage of haze concentration is implemented in initialization phase, and an indicator of video definition is used to control the procedure of subsequent module. Experimental results show that the algorithm can effectively improve the contrast and sharpness of video while with highly computational efficiency. The proposed method can meet the needs of video haze removing
The scaling relationship between baryonic mass and stellar disc size in morphologically late-type galaxies

Here I report the scaling relation between the baryonic masses and the scale lengths of stellar discs from $\sim$1000 morphologically late-type galaxies. The baryonic mass-size relation is a single power-law $R_\ast \propto M_b^{0.38}$ across $\sim$3 orders of magnitude in baryonic mass. The scatter in size at fixed baryonic mass is nearly constant and there is essentially no outlier. The baryonic mass-size relation provides a more fundamental description of the structure of the discs than the stellar mass-size relation. The slope and the scatter of the stellar mass-size relation can be understood in the context of the baryonic mass-size relation. For gas-rich galaxies, the stars is no longer a good tracer for the baryons. High baryonic mass, gas-rich galaxies appear to be much larger at fixed stellar mass because most of the baryonic content is gas. The stellar mass-size relation thus deviates from the power law baryonic relation and the scatter increases at the low stellar mass end. Those extremely gas-rich low-mass galaxies can be classified as Ultra Diffuse Galaxies based on the structure.
Effects of Index Reconstitution under Different States of Market

To analyze the response of stock prices on announcement of initially addition and deletion of the firms in the index (KSE) in different states of market, the sample of 104 for added firms and 103 for deleted firms for the period of 10-years 2001- 2010 is covered by this study. Karachi Stock Exchange, KSE, has been witnessed to face different states of market: Normal, Boom & Recession due to many macro-economic factors. The event study methodology is employed by using three models; capital asset pricing model (CAPM), Market Model (MM) and Market Adjusted Model (MAM) to confine the index reconstitution effects as regards to ARs, Abnormal Returns, CARs, Cumulative Abnormal Returns and Volume Ratio. This study divulges that under normal state of market, the added firms showed significant +ve ARs of 1.14% and 1.10% by using MAM and MM respectively, while insignificant abnormal returns of 0.96% by the CAPM on the event day. Likewise, under boom state of market, these ARs were also observed to a little bit stumpy but remained significant by using CAPM, MAM & MM. Interestingly, under recession state of market, by using CAPM, MAM & MM, the added firms in the index witness with improved significant +ve abnormal returns of around 2%, on the event day window. In contrast, for deleted firms, no significant ARs were examined by CAPM, MAM & MM under normal, boom & recession states of market, except significant +ve ARs of 0.85% by MM under normal state of market. Various event days like 15 th , 10 th , 5 th before or after showed no significant ARs & CARs under different states of market ()except few one. Conversely, CAPM, MAM & MM showed few contradictory and few consistent results for CARs & ARs under different states of market and in different event window days. Unexpectedly, volume ratio (VR) was unable to show any abnormality of trading volume on the event day
Estilos y enfoques de aprendizaje: perspectiva de estudiantes de ingeniería

Los enfoques de aprendizaje mantienen una relacion muy estrecha con las motivaciones y estrategias que tienen los estudiantes en la realizacion de actividades academicas y, consecuentemente, en los resultados que obtenga. Un estudiante con un enfoque de aprendizaje profundo tiene un compromiso real hacia el entendimiento significativo de las tareas que se encomiendan y aplica las estrategias adecuadas para el logro de sus objetivos. Considerando lo anterior, el objetivo de este articulo de investigacion se centro en analizar los estilos de aprendizaje adoptados por los estudiantes de una carrera de ingenieria en Mexico que favorecen enfoques de aprendizaje profundo y superficial. Se realizo una investigacion cuantitativa por encuesta en la que participaron 320 estudiantes. Los resultados encontrados en ambos enfoques de aprendizaje (profundo y superficial) revelaron coincidencias en los estilos de aprendizaje: activo ligero, lo cual refleja que se prefiere la realizacion de actividades fisicas y de experimentacion; visual moderado, que indica la eleccion de que la informacion sea presentada mediante organizadores graficos, lineas de tiempo y demostraciones; y secuencial ligero, esto es, les agrada que la informacion sea presentada paso a paso, de forma ordenada. Siendo diferentes en ambos enfoques en la intensidad con el que se adopta el estilo de aprendizaje sensitivo, esto refleja la forma en que sus sentidos y su mente perciben el mundo. Los estudiantes que adoptan un enfoque de aprendizaje profundo tienen un equilibrio en esta dimension.
Endometrial Metastasis from Breast Carcinoma Simulating a Primary UterineMalignancy

Metastases in the female genital tract occur from cancers that arise in various anatomic sites [1]. The ovary is the most common metastatic site followed by the vagina, cervix, uterine corpus, and fallopian tubes. Among extra genital cancers metastasizing to the uterine corpus, breast is the most common primary site [2]. Lobular carcinoma is the most common type of breast carcinoma that metastasizes to the uterus [3]. We herein report a case of uterine metastasis in a postmenopausal woman who had infiltrating lobular carcinoma of the breast.
Real Exchange Rate And Elasticity Of Labor Supply In A Balance-Of-Payments-Constrained Macrodynamics

A macrodynamic model is proposed in which the real exchange rate and the elasticity of labour supply interact defining different trajectories of growth and income distribution in a developing economy. Growth depends on imports of capital goods which are paid with exports (there are no capital flows) and hence is constrained by equilibrium in current account. The role of the elasticity of labour supply is to prevent the real exchange rate from appreciating as the economy grows, thereby sustaining international competitiveness. The model allows for endogenous technological change and considers the impact of migration from the subsistence to the modern sector on the cumulative (Kaldor-Verdoorn) process of learning.

Thermal performance modelling of data centre– a case study

This paper presents a computational study of thermal modelling of the data centre located at CQUniversity, Rockhampton Campus, Australia. The data centre was modeled and analyzed using computational fluid dynamics (CFD) model to study the effectiveness of cooling within the racks and aisles of the centre. CoolSim- software was used for designing a graphical user interface (GUI) that allows data centre components to be positioned, sized and characterized in a plan view. Modelling of airflow and temperature distribution in the data centre was performed using the CFD code Fluent. The CFD model based on thermal mass and energy balance principles was calibrated with the actual measurements of energy consumption, pressure and temperature from a standard rack filled with a set of rack mounted processor and storage units. The simulation results identified the potential high temperature zone within the computer rack in the data centre, and provide a detailed 3D analysis of how cold air is moving through the data centre. The results also provide the performance analysis of computer room air conditionings (CRACs), detailed rack-by-rack inlet and exit temperatures and 3D thermal mapping of the data centre and racks highlighting trouble areas. The model developed was capable of evaluating the airflow rates and thermal loads for optimizing and designing a new or existing data centre.
On the feasibility of a thermodynamic combined heating-depressurization process and the direct use of surface wind energy for mining the Martian regolith for water

In this paper a combined heating-depressurization process for mining water from the regolith of Mars is proposed and its feasibility discussed. It is shown that for water content in the regolith 4 %, wt  as found in latitudes between 0 45  and 0 45 , a combined heating-depressurization process offers better energy usage performance, with savings up to 40% possible. Utilizing a simplified geometrical model, an analytical expression for the performance of such combined processes in comparison with traditional heating is derived. Finally, the direct use of surface wind energy as a driving force for depressurization-sublimation is assessed, showing that for any season and any water content in the regolith a rudimentary low-tech windmill could provide the water for the design reference missions for human exploration of Mars. These results can make an important contribution to the design of energy strategies for water mining from the regolith in, for example, the conception and design of new rover vehicles.
Extended nebular emission in CALIFA early-type galaxies

Abstract The morphological, spectroscopic and kinematical properties of the warm interstellar medium (wim) in early-type galaxies (ETGs) hold key observational constraints to nuclear activity and the buildup history of these massive quiescent systems. High-quality integral field spectroscopy (IFS) data with a wide spectral and spatial coverage, such as those from the CALIFA survey, offer a precious opportunity for advancing our understanding in this respect. We use deep IFS data from CALIFA (califa.caha.es) to study the wim over the entire extent and optical spectral range of 32 nearby ETGs. We find that all ETGs in our sample show faint (Hα equivalent width EW(Hα)∼0.5 … 2 Å) extranuclear nebular emission extending out to ≥2 Petrosian50 radii. Confirming and strengthening our conclusions in Papaderos et al. (2013, hereafter P13) we argue that ETGs span a broad continuous sequence with regard to the properties of their wim, and they can be roughly subdivided into two characteristic classes. The first one (type i) comprises ETGs with a nearly constant EW(Hα)∼1–3 Å in their extranuclear component, in quantitative agreement with (even though, no proof for) the hypothesis of photoionization by the post-AGB stellar component being the main driver of extended wim emission. The second class (type ii) consists of virtually wim-evacuated ETGs with a large Lyman continuum (Lyc) photon escape fraction and a very low (≤0.5 Å) EW(Hα) in their nuclear zone. These two ETG classes appear indistinguishable from one another by their LINER-specific emission-line ratios. Additionally, here we extend the classification by P13 by the class i+ which stands for a subset of type i ETGs with low-level star-forming activity in contiguous spiral-arm like features in their outermost periphery. These faint features, together with traces of localized star formation in several type i&i+ systems point to a non-negligible contribution from young massive stars to the global ionizing photon budget in ETGs.
Height-diameter relationships of tropical Atlantic moist forest trees in southeastern Brazil

Site-specific height-diameter models may be used to improve biomass estimates for forest inventories where only diameter at breast height (DBH) measurements are available. In this study, we fit height-diameter models for vegetation types of a tropical Atlantic forest using field measurements of height across plots along an altitudinal gradient. To fit height-diameter models, we sampled trees by DBH class and measured tree height within 13 one-hectare permanent plots established at four altitude classes. To select the best model we tested the performance of 11 height-diameter models using the Akaike Information Criterion (AIC). The Weibull and Chapman-Richards height-diameter models performed better than other models, and regional site-specific models performed better than the general model. In addition, there is a slight variation of height-diameter relationships across the altitudinal gradient and an extensive difference in the stature between the Atlantic and Amazon forests. The results showed the effect of altitude on tree height estimates and emphasize the need for altitude-specific models that produce more accurate results than a general model that encompasses all altitudes. To improve biomass estimation, the development of regional height-diameter models that estimate tree height using a subset of randomly sampled trees presents an approach to supplement surveys where only diameter has been measured.
What Price Compromise? Testing a Possibly Surprising Implication of Nash Bargaining Theory

This paper identifies, and tests experimentally, a prediction of Nash Bargaining Theory that may appear counterintuitive. The context is a simple bargaining problem in which two players have to agree a choice from three alternatives. One alternative favours one player and a second favours the other. The third is an apparently reasonable compromise, but is in fact precluded as an agreed choice by the axioms of Nash Bargaining Theory. Experimental results show that agreement on this third alternative occurs rather often. So the axiomatic Nash theory is not well-supported by our evidence. Our subjects' behaviour could be interpreted as the paying of an irrationally (according to the Nash theory) high price in order to reach a compromise agreement.
The Integrated Environment for Learning Objects Design and Storing in Semantic Web

There is a variety of tools and environments for Learning Objects (LOs) design and delivery as well as learning object repositories (LOR) but the researchers could not find a repository that includes both functions: creation and storing of LOs. A number of different integrated learning systems are suggested for users that demonstrate the variety of e-learning methods and semantic capabilities. LO repository oer.ndma. lt/lor, that we are going to present, is very friendly and interoperable to use and assure LO design, search in semantic web, adaptation of the re-used objects and storing. There are no more existing LO repositories with the functionality presented by researchers. Transformation of closed education into open one without existence of well-structured, multifunctional and integrated environment becomes problematic. Authors will present an integrated environment for the LO design, search in semantic web, adaptation and storing of newly designed or re-designed LO. Measures will support the transformation of closed education into open and will assure effective design, re-usability and adaptation of LO in the integrated environment.
Articulation disorders and patterns in children with a cleft

Background: Compensatory articulation disorders (CAD) are the most common speech defects in patients with a cleft. Early prevention programs are needed to avoid CAD. Objectives: To examine articulation disorders, patterns, and related speech outcomes in children with a cleft palate with or without lip defects. Methods: Articulation test record forms and clinical records of 42 children were accessed retrospectively to provide the data of speech outcomes related to cleft palate. Double data entries and incorrect completion type errors were corrected. Results: Prevalence of articulatory defects was 88% (functional articulation disorders, 12%; compensatory articulation disorders, 10%; functional articulation disorders and CAD, 67%), resonance disorder was 50%, and voice abnormalities was 19%. Abnormal backing of oral consonants, particularly glottal substitution was the most common pattern of CAD (40%), follow by velar substitution (36%), and nasal consonant for oral pressure consonant (21%). There was high incidence of functional articulation disorder in patients with a cleft (76%). Younger children (≤7 years old) had more articulation defects than older children (>7 years old) (mean difference = 3.308, P = 0.002, 95% confident interval 1.683−6.971). Levene’s test for equal variance found that resonance disorder seems unaffected by the number of articulation errors (mean difference = 0.253, P = 0.897, 95% confident interval –3.736−4.241). Conclusion: CAD, particularly abnormal backing of oral consonants and hypernasality were the most common speech defects in children with cleft. Refinement and revision of timing for referring for early speech intervention should be reconsidered.

Preliminary fabrication of biodegradable polymer membranes from renewable resources

A membrane is an interphase between two adjacent phases acting as a selective barrier, regulating the transport substances between the two components. Microporous membranes with controlled pore size and structure were produce from biodegradable polymer based on vegetable oil monomer using phase inversion technique. The optimal conditions for the preparation of microporous polymer membranes was polymer concentrations in N,N-dimethylformamide (DMF) solution 12% (w/v), 15% (w/v), 18% (w/v) and 21% (w/v). The result, the membranes show two types of structure: pinhole-like structure and interconnected network structure. The structure of the membranes consisted of thick fibrillar elements. The membrane cross-section seemed to be composed of stacks of separate layers. Permeability of the polymer membranes obtained at lower concentrations, exhibit extremely higher water permeability with value 0.160952, 0.01482, 0.00098 and 0.00051 L/s.m3 for 12%, 15%, 18% and 21% (w/v) respectively. As the concentration increases, the surface layer of the membranes becomes thicker. Thus, the membranes are easily break compared to the membranes that have densely packed as shown by tear test of 12%, 15%, 18%, and 21% (w/v) with 21.8495 N/mm, 13.9566 N/mm, 10.5433 N/mm, and 12.1662 N/mm tear strength respectively. The fabrication of the polymer membranes with the structure and permeability properties was successfully conducted achieved as a novel research as indicated in many work. Applications of these polymer membranes are use for water treatment, skin wound cover and, in combination with autogenous chondrocytes, as an ‘artificial periosteum’ in the treatment of cartilage defects.
Examining the Policies in Turkey That Have Been Implemented during the Structural Reform Process from the Standpoint of Growth-Unemployment

In this study, the change and transformation that has been experienced in the Turkish economy within the progress of structural reforms are being probed and by breaking down the relationship between economic growth and unemployment in a dynamic manner, the reasons that the consistent growth rate that has been reached within the structural reform process had such a low level of impact on creating employment and decreasing unemployment are being discussed. In line with this aim, as is discussed in the literature, whether or not there is a fraction in the relationship between the economic growth and unemployment was tested using Zivot-Andrews (1992) Structural Test and in this scope, the work was examined by dividing it into two sub-periods as 1980-2001 and 2002-2011. The direction and the size of the relationship between the given variables have been researched by utilising Johansen co-integration and error correction model.
Towards Semantic Facility Data Management

Nowadays, facility management is realized with different information systems, which provide a comprehensive view for the management. Building Information Modelling (BIM) encompasses a computer model of a facility, which is utilized throughout the life-cycle of the building. To enable a more holistic view on facilities’ conditions (e.g., energy efficiency, indoor environment, maintenance and repair) we present an approach which enhances the BIM model with semantic indoor measurement data. The enhanced semantic information provides more contextual information about the building; history of conditions, current conditions, and even predictions about the future conditions. In addition, the system ties facility users into the process of facility management by allowing them to view the current indoor conditions and give feedback about the conditions of the building. The resulting semantic facility data management approach was tested in an experiment in which the system was applied in a school building environment.
