Identification of Encrypted Video Streaming Based on Differential Fingerprints
Venue: IEEE INFOCOM 2020 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)
Year: 2020

Nowadays, because of the convenience and broad reach of social media platforms, such as YouTube, Facebook, and Twitter, terrorists have been taking advantage of these platforms to spread illegal videos. Existing researches extract video fingerprints based on statistical data and inevitably overlook some features, which makes it impossible to accurately represent the encrypted video streaming. Besides, almost no research can identify the target video from a large video dataset on the premise of high accuracy and low false positive rate. Therefore, in this paper, we extract differential fingerprints to represent the encrypted video streaming more accurately and identify the encrypted video streaming using our local sequence alignment algorithm. We conduct our method on a large dataset containing 200,000 videos. The results show that by continuously sniffing the encrypted video streaming for 12 seconds, the precision of our method can exceed 98% and the false positive rate is nearly 0.

Ozonation of trace organic compounds in different municipal and industrial wastewaters: Kinetic based prediction of removal efficiency and ozone dose requirements
Year: 2020

For the wide application of ozonation in (industrial and municipal) wastewater treatment, prediction of trace organic compounds (TrOCs) removal and evaluation of energy requirements are essential for its design and operation. In this study, a kinetics approach, based on the correlation between the second order reaction rate constants of TrOCs with ozone and hydroxyl radicals OH) and the ozone and OH exposure (i.e. [O3]dt and OH]dt, which are defined as the time integral concentration of O3 and OH for a given reaction time) was validated to predict the elimination efficiency in not only municipal wastewaters but also industrial wastewaters. Two municipal wastewater treatment plant effluents from Belgium (HB effluent) and China (QG effluent) and two industrial wastewater treatment plant effluents respectively from a China printing and dyeing factory (PD effluent) and a China lithium ion battery factory (LZ effluent) were used for this purpose. The OH scavenging rate from the major scavengers (namely alkalinity, effluent organic matter (EfOM) and NO2 and the total OH scavenging rate of each effluent were calculated. The various water matrices and the OH scavenging rates resulted in a difference in the requirement for ozone dose and energy for the same level of TrOCs elimination. For example, for more than 90% atrazine (ATZ) abatement in HB effluent (with a total OH scavenging rate of 1.9 x 105 s 1) the energy requirement was 12.3 x 10 2 kWh/m3, which was lower than 30.1 x 10 2 kWh/m3 for PD effluent (with the highest total OH scavenging rate of 4.7 x 105 s 1) Even though the water characteristics of selected wastewater effluents are quite different, the results of measured and predicted TrOCs abatement efficiency demonstrate that the kinetics approach is applicability for the prediction of target TrOCs elimination by ozonation in both municipal and industrial wastewater treatment plant effluents.
Normes d'age d'acquisition objectif des mots et recherche de predicteurs importance du choix de la base de frequence lexicale
Year: 2007

L'objectif premier de ce travail etait de caracteriser les images proposees par Bonin, Peereman, Malardier, Meot et Chalard (2003) en termes d'age d'acquisition (AoA) objectif, recueilli aupres d'enfants ages de 2 6 a 10 11 ans. (http www. unice. fr/ LPEQ/ base_ AoA/ aoa_ intro. php) La comparaison avec les normes en francais des images de Snodgrass et Vanderwart (1980) montre que les nouvelles images correspondent, en moyenne, a des mots plus rares et d'AoA plus tardif. Cependant, correlations et regressions multiples indiquent que les memes facteurs sont impliques dans l'emergence de l'AoA (variabilite d'imagerie et frequence lexicale) a travers les deux jeux d'images. De plus, quelle que soit la base d'images, l'AoA est significativement mieux correle et specifiquement predit par les frequences lexicales du vocabulaire de l'enfant (NOVLEX, MANULEX) que par les frequences calculees sur des corpus du vocabulaire de l'adulte (BRULEX, LEXIQUE)
Potential use of Mucuna bracteate as a Cover Crop for Coconut Plantations in the Low Country Intermediate Zone of Sri Lanka
Year: 2017

Cover crops provide a wide range of ecological and environmental benefits. Mucuna bracteata is one of the leguminous creepers which has superior characteristics such as fast growth, high nitrogen fixation ability, high biomass production, and free from pest and diseases. While this plant has recently been used as a cover crop in rubber plantations in the Wet Zone of Sri Lanka, it has not been tested under coconut cultivation in the Intermediate Zone. Therefore, this study aimed to assess the suitability of Mucuna bracteata as a cover crop in coconut plantation in the Low Country Intermediate Zone of Sri Lanka. Four treatments tested in the experiment were, T1 Mucuna bracteata planted in two rows, T2 Mucuna bracteata planted in three rows, T3 Mucuna bracteata planted in four rows in center of square under coconut cultivation and T4 Coconut without cover crop (control) The treatments were arranged in a randomized complete block design with four replicates. Soil chemical and physical properties were analyzed at 5 cm 25 cm depth. The ground cover, weed density and total biomass production were also evaluated in different planting systems. The highest ground coverage and the lowest weed density were observed in coconut with Mucuna bracteata in three rows at 75 days after field establishment. Mucuna bracteata planted plots had significantly lower bulk density, higher organic carbon content than the control and there was no significant bracteata planted in three rows is the most suitable planting method being able to give better ground cover, lower soil bulk density and higher soil nitrogen than other treatments. According to the results of the study, it can be concluded that Mucuna bracteata could be well grown as a cover crop under coconut in the Intermediate Zone of Sri Lanka. Also, it can be suggested that Coconut with Mucuna bracteata planted in three rows is the most suitable planting method being able to give better ground cover, lower soil bulk density and higher soil nitrogen than other treatments.
Sources of Psychological Stress among Undergraduate Students of Allied Health Sciences in Government College University Faisalabad
Year: 2019

The epidemiology of the stress is not well known. The reason behind this is, very few studies have been conducted about allied health sciences students. This study may act as pioneer studies that focus on all the sources and causes of stress among the students in Government College University Faisalabad.  This study was a type of observational study, cross sectional survey. This type of study is quite brief and easy to understand so it was done. A questionnaire was made which comprised of all the necessary questions to be asked from the students. It included demographic information such as gender, degree, semester, and age of the students to get the idea from where the student belongs. It includes all the questions about sources of stress which they were facing while studying in the university.  It has been inferred that furnishing of labs, clinical rotation, dealing with criticism related to academics, major cause of stress that is any complex, financial responsibilities, job expectation and insecurity about future employment are the factors that increased or decreased the stress per day among the students.

Khaled Hosseini's The Kite Runner: Unveiling the Trauma of Adolescent Boys Trapped in Afghanistan's Culturally Legitimised Paedophilia 'Bacha Bazi'
Year: 2020

Khaled Hosseini's The Kite Runner is a powerful narrative on 'Bacha Bazi' "same sex pedophilia restricted to adult men and adolescent boys" (Powell, 2018, p.1) prevalent in Afghanistan. When marginalisation of Afghan women became the nucleus of major studies especially during the Taliban regime in Afghanistan, Hosseini unveiled in The Kite Runner, the gruesome Afghan culture of 'Bacha Bazi' that disintegrates a boy's social and sexual identity. 'Bacha Bazi' is not consensual rather coercion hence is equivalent to rape and reflects the grotesque violation of Afghan male children's human rights. While the world viewed Afghanistan as a land of incessant wars, tribal conflicts, violence and female exploitation, Khaled Hosseini's The Kite Runner provided a startling insight into 'Bacha Bazi' and its implications on Afghan boys. The novel reveals the socio culture domain of Afghanistan and ethnic rivalry playing an instrumental role in the existence of Bacha Bazi. In the light of the above discussions, the present paper examines the deleterious effects of Bacha Bazi on Afghan male children. It elucidates the psychological trauma of adolescent Afghan boys that evolves out of the sexual abuse and new androgynous identity imposed on them.
Position measurement system for linear induction motor applied in electromagnetic emission system
Year: 2015

Position measurement system is very important for linear induction motor normal operation in electromagnetic emission. The static and dynamic operating characteristics of eddy current sensor which was suitable for electromagnetic emission special application cases were studied deeply. The stator of the linear induction motor was constituted by many sections. Based on the specialty,a novel position measurement system was proposed. And then,the design method and derivation process of the measurement system parameters was analyzed based on the study on sensors characteristics and system topology. Finally,a practical prototype of position measurement was developed. Experiments were processed on practical electromagnetic emission system. Experiment results verify the validity and correctness of the design theory and design method proposed.
Analysis of spatio temporal variability of surface groundwater interactions in the Gharehsoo river basin, Iran, using a coupled SWAT MODFLOW model
Venue: Environmental Earth Sciences
Year: 2019

Although groundwater and surface water are often treated as individual water compartments in hydrological cycle studies, they essentially originate from one source. Such a split approach restricts the optimal usages of these water resources in several water management applications. The present study aims to shed light on the complex interaction of surface groundwater interactions in terms of groundwater recharge from drainage network towards the adjacent aquafer and conversely, groundwater discharge from the aquifer towards the drainage network in the Gharehsoo River Basin (GRB) with the enclosed Ardabil aquifer, located in northwest Iran. To that end, the Soil and Water Assessment Tool (SWAT) as the surface hydrological model was fully coupled with the latest version of the Modular Three Dimensional Finite Difference Groundwater Flow (MODFLOW NWT) (Newton Raphson Technique to improve the solutions of unconfined groundwater flow problems) The total study period, i.e. 1978 2012 was split into two intervals for calibration (1988 2012) and validation (1978 1987) To facilitate and expedite the calibration of the coupled model, first we calibrated SWAT and MODFLOW NWT independently against the observed streamflow and groundwater head time series, respectively. Afterwards, we recalibrated the coupled model SWAT MODFLOW. To link these two models, the surface and sub surface water flow components are exchanged between the Disaggregated Hydrological Response Units (DHRUs) of SWAT with the MODFLOW NWT' grid cells. In addition, three more flow components are sequentially exchanged: the deep percolation from SWAT to MODFLOW NWT, baseflow/groundwater discharge from MODFLOW NWT to SWAT, and the river heads from SWAT to MODFLOW NWT. The results of the application show that the coupled model satisfactorily, quantified by R2 0.5, simulates streamflow and particularly, groundwater heads. In fact, both observations and simulations indicate that, owing to an ongoing overexploitation of the aquifer, heads have been decreased steadily over the studied period which has led to a parallel decline of the groundwater storage. Moreover, the analysis of the stream aquifer exchange flows indicates that groundwater discharge towards the stream network (effluent conditions) is orders of magnitude higher than the opposite process (influent conditions) In addition, findings reveal that many of the tributaries across the GRB have shifted from a perennial regime to ephemeral/intermittent system over the past decades. The provided and well tested coupled model would be a viable asset to assess a wide range of plausible scenarios to identify most effective and practical water resource management schemes to recover the severely depleted surface water and groundwater resources of the GRB.
k GANs: Ensemble of Generative Models with Semi Discrete Optimal Transport
Venue: ArXiv
Year: 2019

Generative adversarial networks (GANs) are the state of the art in generative modeling. Unfortunately, most GAN methods are susceptible to mode collapse, meaning that they tend to capture only a subset of the modes of the true distribution. A possible way of dealing with this problem is to use an ensemble of GANs, where (ideally) each network models a single mode. In this paper, we introduce a principled method for training an ensemble of GANs using semi discrete optimal transport theory. In our approach, each generative network models the transportation map between a point mass (Dirac measure) and the restriction of the data distribution on a tile of a Voronoi tessellation that is defined by the location of the point masses. We iteratively train the generative networks and the point masses until convergence. The resulting k GANs algorithm has strong theoretical connection with the k medoids algorithm. In our experiments, we show that our ensemble method consistently outperforms baseline GANs.
Meeting the Physical and Mental Health Needs of Older Offenders: Does Aging in Place Work in Prison?
Venue: Innovation in Aging
Year: 2020

In many countries, the proportion of older people in prison is growing due to longer sentences, increases in convictions for historical offences, and longevity. Moreover, harsh conditions of confinement coupled with the negative effects of a criminal lifestyle may contribute to 'accelerated aging' in this population. Indeed, many prisoners develop health problems that are more commonly seen among people who are up to ten years older. Correctional institutions are increasingly struggling to meet the complex and expensive healthcare needs of these offenders, especially at end of life. Some institutions have taken the position that prisons were never intended to be nursing homes, nor can they be adequately adapted to fulfill this role. As a result, these institutions attempt to place some aging offenders in healthcare institutions within the community, provided that their risk to the public can be adequately managed. Other institutions have argued that the needs of aging offenders can be successfully met behind prison walls and have taken steps to allow prisoners to 'age in place. After summarizing the research on the physical and mental health needs of aging offenders, this presentation considers the advantages and disadvantages of meeting older offenders' healthcare needs both within and outside the prison setting and provides relevant examples of both. Special attention is paid to the issues of social isolation and loneliness: both may contribute to accelerated aging, and perhaps even the risk for re offending, raising questions about which correctional settings are most beneficial for minimizing these problems.
Elusive Identities: Karoo |Xam Descendants and the Square Kilometre Array
Venue: Journal of Southern African Studies
Year: 2019

In 2007, in order to facilitate the building and operations of the Square Kilometre Array (SKA) the Astronomy Geographic Advantage Act proclaimed a large 'astronomy reserve' in the central Upper Karoo, a roughly rhombic space covering some 120,000 square kilometres. As it happens, this geographic reserve coincides almost exactly with a region described by |Xam prisoners of the mid 19th century as |Xam ka! au, their homeland. We show how archival records indicate that |Xam descendants are still living in the space now reserved for astronomy and how the claims of the Kalahari communities represented in the South African San Council of having once lived in the area lack substance. We compare the |Xam and the SKA notions of landscape, describe the historic evolution from the one to the other and suggest that benefit for local communities can only be in the form of bottom up discussions about the planning of future developments and the distribution of tangible benefits.
Energy Efficient Power Amplifier Design
Year: 2015

Legacy mobile handsets already incorporate multimode features, with dual, tri and quad band functionality already the norm, and the very latest smart phone having WiFi connectivity. However, complete interoperability is still in its infancy with several hurdles still to overcome, and energy efficiency is one of them. Unless mobile handsets are smart enough to be energy aware and flexible in switching between several standards, the 5G slogan of anytime, anywhere connectivity could remain a "vision" rather than close to market. To attain true energy efficiency lays down stringent design requirements on the RF system that in today's handset is a key consumer of power. In fact the power amplifier is the main culprit for stealing energy from the battery supply, and the reason why mobile handset become hot after a lengthy call. This effect will multiply when ubiquitous broadband connectivity becomes the standard, leading to significant research on active cooling, considering approaches similar to fan techniques in laptop and desktop devices. However, rather than trying to reduce the effects of overheating, we aim to tackle the problem at the bud, by considering energy efficient designs. In fact, this chapter is the sequel to the former that was dedicated to the study of new designs for hardware components that can provide truly flexible and energy efficient multi standard transceivers. This chapter completes this study by focusing on energy efficient power amplifier design. We consider three innovative designs, to operate at varying operating frequencies, covering the frequency bands 400 MHz, 1,920 MHz and 3.5 GHz. The proposed RF Power Amplifiers show considerable enhancements compared to the state of the art existing technologies.
Desarrollo de la oralidad y la escucha en los ninos de preescolar del primer ciclo a partir de la literatura infantil
Year: 2018

Esta propuesta de investigacion surge de generar una reflexion significativa acerca de las estrategias didacticas y pedagogicas que se generan desde el aula de clase en la escuela vinculando a la familia, en la busqueda del fortalecimiento de las habilidades comunicativas de expresion oral y de escucha en los ninos de preescolar primer ciclo, con la practica de la literatura infantil como herramienta de trabajo de las experiencias escolares y familiares. Debido a la importancia que resignifica y asume el texto en la construccion de la voz en los distintos ambitos que rodean al nino, el lenguaje privilegia las practicas sociales y culturales en la construccion de conocimiento en cada uno de los escenarios desde los primeros anos de vida, complementandose en la primera infancia a partir del trabajo consecuente de las dimensiones comunicativa, cognitiva, socio afectiva, corporal y artistica de su desarrollo integral en la escuela.
Deep Learning for Facial Beauty Prediction
Venue: Inf.
Year: 2020

Facial beauty prediction (FBP) is a burgeoning issue for attractiveness evaluation, which aims to make assessment consistent with human opinion. Since FBP is a regression problem, to handle this issue, there are data driven methods for finding the relations between facial features and beauty assessment. Recently, deep learning methods have shown its amazing capacity for feature representation and analysis. Convolutional neural networks (CNNs) have shown tremendous performance on facial recognition and comprehension, which are proved as an effective method for facial feature exploration. Lately, there are well designed networks with efficient structures investigated for better representation performance. However, these designs concentrate on the effective block but do not build an efficient information transmission pathway, which led to a sub optimal capacity for feature representation. Furthermore, these works cannot find the inherent correlations of feature maps, which also limits the performance. In this paper, an elaborate network design for FBP issue is proposed for better performance. A residual in residual (RIR) structure is introduced to the network for passing the gradient flow deeper, and building a better pathway for information transmission. By applying the RIR structure, a deeper network can be established for better feature representation. Besides the RIR network design, an attention mechanism is introduced to exploit the inner correlations among features. We investigate a joint spatial wise and channel wise attention (SCA) block to distribute the importance among features, which finds a better representation for facial information. Experimental results show our proposed network can predict facial beauty closer to a human's assessment than state of the arts.
