The Amount of Excess Cash Holdings and Their Influence on Abnormal Returns in IPO's in Tehran Stock Exchange
Year: 2014

This study investigates the extent of surplus cash holdings and their influence on abnormal returns in initial public offerings of stock in Tehran Stock Exchange. The 101 companies during the period 2003 to 2012 were selected. Selective approach to testing hypotheses, examining cross sectional data Regression testing analysis and compared statistically independent samples was used to test hypotheses. The results show that the retention surplus cash holdings by firms and abnormal returns in initial public offerings of stock, the general relationship in between. In general, there is no significant relationship. But tests determined that for each year of the procedure, it was determined for each year. During the 2005 years (significant negative association) and 2009 years (significant positive relationship) there also was the stability of the cash surplus items stored during some years now have changed and so we can say is unsustainable. Given the similarity of the average abnormal returns varied over the study period, one can say that the variable of interest over the years has remained stable. During the years of said, the variable of interest has remained stable.
Plan de negocios para la creacion de un servicio de peluqueria y estetica movil que preste servicios de masajes expres, tratamientos faciales, cepillados, maquillajes y depilacion en la ciudad de Quito
Year: 2018

The present business plan seeks to determine the feasibility and viability of the creation of a mobile hairdressing and aesthetic service, which provides its services in the north side of Quito's City. The opportunity of this business is based on the growing tendency of Ecuadorian people for looking and feeling better, however, due to external causes such as: lack of time, long hours of work, various daily activities, heavy traffic or the difficulty of transportation in the city have limited their frequency of visit to the beautiful hairdressing places that exist in the city. The current woman multitasks and they always seek to optimize her time, this factor being one of the most decisive when choosing a beauty hairdressing center. For this reason, the business idea represents a great opportunity in the current market. Nowadays, women are needing to maintain a good appearance for themselves, due to a lot of occupations and they do not have enough time to devote to caring for themselves and it saw the need to create a Center for Hairdressing and Aesthetic Mobile in order to optimize their time and increase the frequency of use of beauty services, saving their time avoiding traffic and the stress of moving. This project pretends to get to women between 20 and 50 years old who were economically active, belonging to class B and C of the North side of the Metropolitan District of Quito and whom a value offer will be presented that solves the requirements of mobile personal care, supported by a functional infrastructure that allows carrying out the operations of the business turnaround in a fast and effective way for the clients that it is counting on staff and adequate tools at the time of providing the service. The strategy for entering to the market will be "more for more" It means that it is more expensive to establish prices than the competition, with the difference that it will be added a small value in the service what it is the mobile service, so it is saving the time and stress of the transfer.
Crystal Loss and Quality Pooling for Unconstrained Face Verification and Recognition
Venue: ArXiv
Year: 2018

In recent years, the performance of face verification and recognition systems based on deep convolutional neural networks (DCNNs) has significantly improved. A typical pipeline for face verification includes training a deep network for subject classification with softmax loss, using the penultimate layer output as the feature descriptor, and generating a cosine similarity score given a pair of face images or videos. The softmax loss function does not optimize the features to have higher similarity score for positive pairs and lower similarity score for negative pairs, which leads to a performance gap. In this paper, we propose a new loss function, called Crystal Loss, that restricts the features to lie on a hypersphere of a fixed radius. The loss can be easily implemented using existing deep learning frameworks. We show that integrating this simple step in the training pipeline significantly improves the performance of face verification and recognition systems. We achieve state of the art performance for face verification and recognition on challenging LFW, IJB A, IJB B and IJB C datasets over a large range of false alarm rates (10 1 to 10 7)
The associations between mental health, health related quality of life and insulin pump therapy among children and adolescents with type 1 diabetes
Venue: Journal of pediatric endocrinology metabolism JPEM
Year: 2018

Diabetes has previously been linked to mental health problems in children and adolescents, but more recent studies have yielded mixed findings. The aim of the current study was to compare symptoms of mental health problems in children and adolescents with and without type 1 diabetes (T1DM) Methods Life quality, subjective well being, self rated health, depression and somatic symptoms in children and adolescents with diabetes (n=130) were measured and compared to the results of a socio demographically joined control group (n=177) which consists of healthy children and adolescents.  A significant difference could be observed between the groups in well being and depressive symptoms as according to the results, the research sample namely the children with T1DM could be described with significantly higher subjective well being and mood, but with less physical symptoms and lower level of depression as those in the control group.  These findings suggest that T1DM is not associated with an increased risk of psychosocial problems, and confirm that even a severe disease of a child can lead to personal growth.

A review on the design and development of photocatalyst synthesis and application in microfluidic reactors: challenges and opportunities
Venue: Reviews in Chemical Engineering
Year: 2019

Microfluidics is an emerging branch of science that has significant applications in various fields. In this review paper, after a brief introduction to the concept of photocatalysis, nanoparticle preparation methods and film formation techniques have been studied. Nanoparticle synthesis in microfluidic systems and microreactor types for on chip photocatalyst synthesis and challenges of nanoparticles handling in microsystems have been reviewed. To resolve particle polydispersity and microchannel clogging, a good suggestion can be the use of droplet based microreactors. The configurative designs for the microfluidic reactor with immobilized photocatalysts, their applications, and their challenges have been comprehensively addressed. The three main challenges ahead the immobilized photocatalytic microfluidic reactors are optimal light distribution, prevention of the recombination of photogenerated electrons and holes, and improved mass transfer. Internal light emitting diodes with a waveguide can resolve the number one challenge of photocatalysis application in optofluidic reactors, that is, light distribution.
Reduced converter topology for integrated wind and small hydro energy generation system
Year: 2015

This study presents a robust and cost effective microgrid topology for integrating two commonly available wind and small hydro renewable energy sources. The proposed topology has two generators, one of them is self excited squirrel cage induction generator driven by a small hydro turbine and other one is permanent magnet brushless DC generator driven by a small scale wind turbine. The proposed system is integrated using a voltage source converter and a boost converter which are maintaining voltage and frequency, mitigating power quality problems and performing mechanical sensorless maximum power point tracking, respectively. A battery bank is also used to balance the load and supply power mismatch and to ensure the supply for critical loads. The proposed control algorithm is tested and verified on a developed laboratory prototype of the system. Test results verify that voltage and frequency of the system are regulated and the power quality related issues are also resolved in this microgrid.
Development and Characterization of the Edible Packaging Films Incorporated with Blueberry Pomace
Venue: Foods
Year: 2020

This work focused on the development of starch based (potato, corn, sweet potato, green bean and tapioca) edible packaging film incorporated with blueberry pomace powder (BPP) The optical, mechanical, thermal, and physicochemical properties were subsequently tested. The film color was not affected by the addition of BPP. BPP incorporated into corn and green bean starch films showed increased light barrier properties, indicating a beneficial effect to prevent UV radiation induced food deterioration. Film thickness and transparency were not primarily affected by changing the starch type or the BPP concentration, although the corn starch films were the most transparent. Furthermore, all films maintained structural integrity and had a high tensile strength. The water vapor transmission rate of all the films was found to be greater than conventional polyethylene films. The average solubility of all the films made from different starch types was between 24 and 37% which indicates the usability of these films for packaging, specifically for low to intermediate moisture foods. There were no statistical differences in Differential Scanning Calorimetry parameters with changes in the starch type and pomace levels. Migration assays showed a greater release of the active compounds from BPP into acetic acid medium (aqueous food simulant) than ethanol medium (fatty food simulant) The incorporation of BPP into starch chitosan films resulted in the improvement of film performance, thereby suggesting the potential for applying BPP into starch based films for active packaging.

Novel technologies and Geopolitical Strategies: Disinformation Narratives in the Countries of the Visegrad Group
Venue: Politics in Central Europe
Year: 2021

In the current media environment of growing information disorder and social media platforms emerging as primary news sources, the creation and spread of disinformation is becoming increasingly easy and cost effective. The projection of strategic narratives through disinformation campaigns is an important geopolitical tool in the global competition for power and status. We have analysed close to 1,000 individual news pieces from more than 60 different online sources containing disinformation, which originally appeared in one of the V4 languages, using a natural language processing algorithm. We have assessed the frequency of recurring themes within the articles and their relationship structure, to see whether consistent disinformation narratives were to be found among them. Through frequency analysis and relationship charting, we have been able to uncover individual storylines connected to more than ten overarching disinformation narratives. We have also exposed five key meta narratives present in all Visegrad Countries, which fed into a coherent system of beliefs, such as the envisioned collapse of the European Union or the establishment of a system of Neo Atlantism, which would permanently divide the continent.
Role of family farming in food and nutrition security
Year: 2014

With increasing pressure of population on land and water resources and prospect of adverse changes in climate, decentralized family farming based on gender, climate and nutrition sensitive agriculture is the pathway for food for all and forever. Given the nature of agricultural land holdings, India is having adequate strength to promote family farming for food security in a big way. The zero hunger vision can be converted into reality, provided family farmers are enabled to sustain their livelihoods based on the principles of ecology, economics, equity and employment.
Global equatorial plasma bubble occurrence during the 2015 St. Patrick's Day storm
Year: 2016

An analysis of the occurrence of equatorial plasma bubbles (EPBs) around the world during the 2015 St. Patrick's Day geomagnetic storm is presented. A network of 12 Global Positioning System receivers spanning from South America to Southeast Asia was used, in addition to colocated VHF receivers at three stations and four nearby ionosondes. The suppression of postsunset EPBs was observed across most longitudes over 2 days. The EPB observations were compared to calculations of the linear Rayleigh Taylor growth rate using coupled thermosphere ionosphere modeling, which successfully modeled the transition of favorable EPB growth from postsunset to postmidnight hours during the storm. The mechanisms behind the growth of postmidnight EPBs during this storm were investigated. While the latter stages of postmidnight EPB growth were found to be dominated by disturbance dynamo effects, the initial stages of postmidnight EPB growth close to local midnight were found to be controlled by the higher altitudes of the plasma (i.e. the gravity term) Modeling and observations revealed that during the storm the ionospheric plasma was redistributed to higher altitudes in the low latitude region, which made the plasma more susceptible to Rayleigh Taylor growth prior to the dominance of the disturbance dynamo in the eventual generation of postmidnight EPBs.
Overview on Phenomenological Pedagogy
Year: 2011

Phenomenological Pedagogy came into being in 1970s.Professor Max Van Manen was one of founders.Phenomenological Pedagogy based on the phenomenology and existentialism.By using of the methodology and epistemology of phenomenology and existentialism Phenomenological Pedagogy encourages parents and teachers pay much attention to children's lived world and realize the aims and values of pedagogy by reflective thinking.Phenomenological Pedagogy cares each special one instead of the whole.The purpose of Phenomenological Pedagogy is to get the meaning of life rather than to sack too much knowledge to children.It also simplifies the research method of phenomenology which makes the common people like parents and teachers can use it freely.

Infectious and Radioactive Waste Management in a Diagnostic and Nuclear Medicine Centre
Year: 2015

Hospital and medical waste management practices are very unsatisfactory in developing countries especially in Pakistan. Existing techniques and practices are not in accordance with the guidelines and levels prescribed by the WHO (World Health Organization) and other international bodies concerned with environment and human health. The objective of this study was to design and implement a proper waste management plan for the PINUM (Punjab institute of Nuclear Medicine) hospital Faisalabad, Pakistan. At PINUM Hospital infectious waste is produced as a result of diagnostic and radioactive waste as a result of diagnostic and therapeutic activities in nuclear medicine. This study was carried out in a period of 10 months in two phases. In first phase a proper infectious waste management plan was designed and incorporated at hospital and in 2nd phase proper management plan for radioactive waste was designed and implemented. Results showed a 43% reduction in volume and treatment cost of infectious waste resulting from proper management. There was significant decrease in prescribed` storage time of radioactive waste which is done to bring its activity to normal level. It was evident from the results if radioactive waste properly segregated, lose radioactive waste (gloves, swabs, absorbing sheets, tissue papers etc. can be disposed off much earlier than the compact radioactive waste (radioactive vials, needles and sharps)
Robust Classification of Crisis Related Data on Social Networks Using Convolutional Neural Networks
Venue: ICWSM
Year: 2017

The role of social media, in particular microblogging platforms such as Twitter, as a conduit for actionable and tactical information during disasters is increasingly acknowledged. However, time critical analysis of big crisis data on social media streams brings challenges to machine learning techniques, especially the ones that use supervised learning. The scarcity of labeled data, particularly in the early hours of a crisis, delays the learning process. Existing classification methods require a significant amount of labeled data specific to a particular event for training plus a lot of feature engineering to achieve best results. In this work, we introduce neural network based classification methods for identifying useful tweets during a crisis situation. At the onset of a disaster when no labeled data is available, our proposed method makes the best use of the out of event data and achieves good results.
On Lions and Elligators: An efficient constant time implementation of CSIDH
Venue: IACR Cryptol. ePrint Arch.
Year: 2018

The recently proposed CSIDH primitive is a promising candidate for post quantum static static key exchanges with very small keys. However, until now there is only a variable time proof of concept implementation by Castryck, Lange, Martindale, Panny, and Renes, recently optimized by Meyer and Reith, which can leak various information about the private key. Therefore, we present an efficient constant time implementation that samples key elements only from intervals of nonnegative numbers and uses dummy isogenies, which prevents certain kinds of side channel attacks. We apply several optimizations, e.g. Elligator and the newly introduced SIMBA, in order to get a more efficient implementation.
Love, Trust, and Camaraderie: Teachers' Perspectives of Care in an Urban High School
Year: 2019

Many scholars have found that student teacher relationships are an integral part to student success in schools. The quality of relationships has implications for student engagement and performance. The most successful student teacher relationships have characteristics of the ethic of care. The purpose of this qualitative study was to examine the perspectives of care of two teachers within a peer learning structured STEM (science, technology, engineering, and mathematics) classroom in an urban high school. In the Peer Enabled Restructured Class (PERC) student facilitators work with teachers to lead instruction. The findings indicated that teachers saw themselves as caring, but their articulations of care varied from authentic care to aesthetic care. The study has implications for teacher preparation and practice as teachers who are prepared and knowledgeable about the importance of relationships and care have the potential for better success with their students.
