Study of Hall Effect Sensor and Variety of Temperature Related Sensitivity
Year: 2017

Hall effect sensors are used in many applications because they are based on an ideal magnetic field sensing technology. The most important factor that determines their sensitivity is the material of which the sensor is made. Properties of the material such as carrier concentration, carrier mobility and energy band gap all vary with temperature. Thus, sensitivity is also influenced by temperature. In this study, current related sensitivity and voltage related sensitivity were calculated in the intrinsic region of temperature for two commonly used materials, i.e. Si and GaAs. The results showed that at the same temperature, GaAs can achieve higher sensitivity than Si and it has a larger band gap as well. Therefore, GaAs is more suitable to be used in applications that are exposed to different temperatures.
Influence of substrate hardness on deposition behavior of single porous WC 12Co particle in cold spraying
Year: 2008

Deposition of a dense coating with solid particles by cold spraying requires sufficient deformation of impacting particles and previously deposited underlying particles. The cermet particles and subsequent coating with a high hardness are difficult to deform upon impact. To increase the ability of deformation, the cermet spray particles with a porous structure are used to fulfill the requirements of deformation on impact. To understand the deposition mechanism, the deposition behaviors of single WC Co spray particles impacting on the substrates with different hardness during cold spraying were examined using WC 12Co powders with different porosities. The substrates with different hardness including stainless steel, nickel based self fluxing alloy coatings were employed to examine the effect of substrate deformation on the cermet particle deposition. It was found that the WC Co cermet particles with the porosities of 30% and 44% could be deposited on the substrate of different hardness from 200 to 800 kgf/mm 2 The deposition of the particles is mainly attributed to the deformation of powders themselves. The properly designed porous cermet powder with certain hardness is necessary to deposit hard WC Co cermet coating.

(INVITED) Methods for determining the refractive indices and thermo optic coefficients of chalcogenide glasses at MIR wavelengths
Venue: Optical Materials: X
Year: 2019

Chalcogenide glasses have attracted much attention for the realization of photonic components owing to their outstanding optical properties in the mid infrared (MIR) region. However, relatively few refractive index dispersion data are presently available for these glasses at MIR wavelengths. This paper presents a mini review of methods we have both used and developed to determine the refractive indices and thermo optic coefficients of chalcogenide glasses at MIR wavelengths, and is supported by new results. The mini review should be useful to both new and established researchers in the chalcogenide glass field and fields of MIR optics, fiber optics and waveguides. Three groups of methods are distinguished: (1) spectroscopic ellipsometry, (2) prism based methods, and (3) methods using Fourier transform infrared (FTIR) transmission data. The mini review is supported by a brief discussion of refractive index models.
Injuries Observed in Minimalist Runners
Venue: Foot ankle international
Year: 2012

Minimalist runners have been shown to have a different gait pattern with lower impact forces than habitually shod runners. Running in minimalist footwear has been promoted as a means of reducing or eliminating running injuries by returning to a more natural gait.  Ten experienced runners, age 21 to 57 (mean, 43) years, were identified with injuries within 1 year of transition from traditional to minimalist running footwear. Patients were interviewed to determine their running history, injury history, transition to minimalist footwear, and their new injury including its treatment and recovery.  Ten patients who ran with traditional footwear ran an average of 25.9 (range, 6 to 45) miles/week for an average of 18.9 (range, 1 to 40) years presented with injuries 2.8 (range 1 to 10) months after switching to minimalist footwear. Their injuries included eight metatarsal stress fractures, a calcaneal stress fracture, and a plantar fascia rupture. All patients had a successful recovery and returned to their previous level of running.  Injuries including stress fractures and plantar fascia rupture have been observed in minimalist runners.
Evaluation of Accuracy of Ideal Gas Heat Capacity and Entropy Calculations by Density Functional Theory (DFT) for Rigid Molecules
Year: 2012

Quantum mechanical calculations, coupled with statistical thermodynamics, provide a means to obtain thermodynamic properties of ideal gas. In this work, we performed density functional theory (DFT) and statistical thermodynamic calculations of ideal gas heat capacities and entropies for a set of 93 rigid molecules, which do not contain large amplitude motions, such as internal rotations or ring puckering, and for which reliable reference data were found in the literature. The effect of the size of basis sets and scale factors was systematically examined and statistically evaluated. The absolute average percentage deviations of the heat capacities and entropies calculated using unscaled harmonic frequencies from reference values were less than 2.5 for all of the basis sets studied. Both heat capacities and entropies were, however, systematically underestimated, and the relative deviations of heat capacities showed a significant temperature dependence with a maximum deviation near ambient temperatures.

"Hey Alexa, What's Up?" A Mixed Methods Studies of In Home Conversational Agent Usage
Venue: Conference on Designing Interactive Systems
Year: 2018

In home, place based, conversational agents have exploded in popularity over the past three years. In particular, Amazon's conversational agent, Alexa, now dominates the market and is in millions of homes. This paper presents two complementary studies investigating the experience of households living with a conversational agent over an extended period of time. First, we gathered the history logs of 75 Alexa participants and quantitatively analyzed over 278,000 commands. Second, we performed seven in home, contextual interviews of Alexa owners focusing on how their household interacts with Alexa. Our findings give the first glimpse of how households integrate Alexa into their lives. We found interesting behaviors around purchasing and acclimating to Alexa, in the number and physical placement of devices, and in daily use patterns. Participants also uniformly described interactions between children and Alexa. We conclude with suggestions for future improvement for intelligent conversational agents.
CellinDeep: Robust and Accurate Cellular Based Indoor Localization via Deep Learning
Venue: IEEE Sensors Journal
Year: 2019

The demand for a ubiquitous and accurate indoor localization service is continuously growing. Current solutions for indoor localization usually depend on using the embedded sensors on high end phones or provide coarse grained accuracy. We present CellinDeep: a deep learning based localization system that achieves fine grained accuracy using the ubiquitous cellular technology. Specifically, CellinDeep captures the non linear relation between the cellular signal heard by a mobile phone and its location. To do that, it leverages a deep network to model the inherent dependency between the signals of the different cell towers in the area of interest, allowing it achieve high localization accuracy. As part of the design of CellinDeep, we introduce modules to address a number of practical challenges such as handling the noise in the input wireless signal, reducing the amount of data required for the deep learning model, as avoiding over training. Implementation of CellinDeep on different Android phones shows that it can achieve a median localization accuracy of 0.78m. This accuracy is better than the state of the art indoor cellular based systems by at least 350% In addition, CellinDeep provides at least 93.45% savings in power compared to the WiFi based techniques.
Reproducing spaces of embeddedness through Islamic NGOs in Sub Saharan Africa: reflections on the post 2015 development agenda
Year: 2017

This paper explores the nexus of religion, space, and development. It sheds light on the role of faith based organizations (FBOs) as partners in sustainable development and key actors for achieving the Sustainable Development Goals in sub Saharan Africa (SSA) Applying and building on the theoretical framework of Polanyi's The Great Transformation indicates that FBOs with value laden agendas have formed new state spaces during the age of globalization, where state capacities are transferred to non state actors at other levels. The case study of Qatari organizations in SSA demonstrates how their uptake of state capacities can lead to development efforts that are driven by faith apart from politics and economics, which help balance market liberalism and social protectionism to create the conditions for sustainable development. Among other things, FBOs offer alternative financing options and new opportunities for financial inclusion that are relevant to the implementation of the post 2015 development agenda.
Impact of complete bladder neck preservation on urinary continence, quality of life and surgical margins after radical prostatectomy: a randomized, controlled, single blind trial.
Venue: The Journal of urology
Year: 2013

We investigated the influence of bladder neck preservation on urinary continence, quality of life and surgical margins after radical prostatectomy.  A total of 208 men who presented for radical prostatectomy were randomized to complete bladder neck preservation with subsequent urethro urethral anastomosis or to no preservation as controls. Patients with failed bladder neck preservation were not included in study. We documented objective continence by the 24 hour pad test, social continence by the number of pads per day and quality of life outcomes by the validated Incontinence Quality of Life questionnaire in a single blind setting. Cancer resection was assessed by surgical margin status.  At 0, 3, 6 and 12 months mean urine loss in the control vs the bladder neck preservation group was 713.3 vs 237.0, 49.6 vs 15.6, 44.4 vs 5.5 and 25.4 vs 3.1 gm, respectively (each p <0.001) At 3, 6 and 12 months in the control vs the preservation group the social continence rate was 55.3% vs 84.2% (p <0.001) 74.8% vs 89.5% (p 0.05) and 81.4% vs 94.7% (p 0.027) and the quality of life score was 80.4 vs 90.3 (p <0.001) 85.4 vs 91.7 (p 0.016) and 86.0 vs 93.8 (p 0.001) respectively. We noted significantly less urine loss, higher objective and social continence rates, and higher quality of life scores after complete bladder neck preservation at all followup points. On multiple logistic regression analysis complete bladder neck preservation was an independent positive predictor of continence. No significant difference was found in surgical margin status between the control and bladder neck preservation groups (12.5% vs 14.7% p 0.65)  In what is to our knowledge the first prospective, randomized, controlled, single blind trial complete bladder neck preservation during radical prostatectomy was associated with a significantly higher urinary continence rate and increased patient satisfaction without compromising resection margins.
Fluidity of law in the United Arab Emirates
Year: 2017

Le concept de "fluidite du droit" interroge les variations de l'application du droit aux Emirats arabes unis (E.A.U. L'intention est de proteger les interets des citoyens emiriens contre les non citoyens tout en imposant le droit des decideurs dans un cadre juridique arabo musulman. Le contexte (acteurs et especes) determine l'adaptation du droit. Les E.A. U. ont signe des traites internationaux qui les obligent a mettre le droit local en conformite. Or, les reserves stipulees et le manque de clarte retardent ce processus. Localement, l'application du droit depend de la variete des sources, notamment du droit islamique et de ses differentes ecoles, d'une procedure legislative opaque et d'un systeme judiciaire complexe (trois types de tribunaux, statut personnel discriminant fonde sur la notion de citoyennete) Les limites fluctuantes entre les spheres publiques et privees font enfin planer une incertitude dans des domaines relevant de l'intime ou de la diffamation par exemple. Les autorites emiriennes exercent un controle sur le droit en s'appuyant sur une organisation tribale et un systeme de permis a tous les etages de la societe emirienne. La liberte d'expression a cet egard a subi les effets du Printemps arabe de 2011. Le systeme de delivrance de permis s'en est trouve renforce pour assurer la stabilite du regime. Le droit a l'education, tres interpretatif, montre comment les permis d'exercice interpretent differemment ce droit. Le droit du travail est aussi encadre par des permis. Les autorites emiriennes sous traitent aux citoyens emiriens le controle des travailleurs etrangers. Dans le contexte d'une croissance economique exceptionnelle, des observateurs exterieurs ont interroge les effets de cette croissance sur les droits de l'homme et les medias. Le gouvernement federal a tres vite appris a utiliser son systeme pour se proteger des droits< universels> Des organisations ecrans ont ete creees pour repondre aux critiques exprimees en insistant sur le point de vue emirien. L'aide etrangere permet en outre d'acquerir un statut privilegier dans le domaine humanitaire. L'intention est de rendre la critique de la fluidite du droit impossible ou injuste. Vu de l'exterieur, bien des decisions emiriennes peuvent etre interpretees comme arbitraires. Or, la fluidite du droit est un principe interne qui a sa logique, celle de preserver l'Etat et de le rendre resilient en cas de contestation.
Advanced Atmospheric Mitigation Decision Aids for Space Imaging and Laser Communications
Year: 2018

Space based imaging often times wastes its onboard resources capturing pictures of the tops of clouds when ground targeting could be easily optimized with the use of atmospheric mitigation decision aids. The interest in the use of space based optical communications, also known as laser communications, is also similarly impacted by clouds and could benefit from similar atmospheric mitigation decision aids in order to optimize its link availability. Laser communications provide secure, high data rate transmission in the absence of strong atmospheric fading that includes cloud liquid water, ice and atmospheric aberrations produced by pancake layer density gradients. A multiyear campaign to understand the impacts of atmospherics on space imaging as well as laser communication signals is underway. This campaign includes quantifying the impacts of the atmosphere on atmospheric data links, and developing operational concepts for mitigating transmission losses due to clouds, turbulence, and aerosols. Advanced atmospheric mitigation decision aids for characterizing and forecasting optical links and for optimizing resources for ground imaging is currently being developed. They include the development and deployment of state of the art instruments designed to measure properties of clouds, including transmission loss, at optical ground sites. An Infrared Cloud Imager and LIDAR ceilometer will together provide high temporal frequency characterization of clouds and cloud transmission in the local skydome. This data will provide an estimate of the atmospheric fading and will be used to make decisions on switching the link from one optical ground site to another. In addition to in situ measurements of clouds, remote sensing geostationary satellites will provide improved resolution of clouds in and near the site as well as regionally around each site in the optical network. Finally, combined use of numerical prediction of atmospherics including cloud and optical turbulence fading and artificial intelligence are underway and will help to optimize ground target resourcing hours and days in advance. Combining local and regional characterization along with high fidelity numerical modeling and deep machine learning is resulting in an optimized atmospheric mitigation decision aid that maximizes availability.

Venue: J. Inf. Sci.
Year: 2006

This paper presents a model for measuring intellectual capital (IC) within small and medium sized enterprises (SMEs) in correlation with the key factors for the successful implementation of knowledge management (KM) Most of the existing IC measurement models are intended to cover general aspects. The kernel of these models could be customized/extended to handle more specific aspects, like KM. The focus of this study is the integration between an IC measurement model and the key factors for successful implementing of KM. The paper identifies, analyses and compares IC elements that are relevant for SMEs and how they can be linked with the IC measurement methods for determining if a company is ready for KM. For this purpose, a general IC measurement model is taken as reference for the study.
Placental Abruption after Bricanyl Injection Prior to External Cephalic Version: A Case Report
Year: 2018

External cephalic version (EVC) is a procedure of fetal rotation to a cephalic presentation at term and tocolysis is often used to contribute to a successful ECV. Tocolysis is contraindicated if placental abruption (PA) is suspected or diagnosed. However, in rare situations it happens, even in the absence of clinical signs.  A 31 year old pregnant woman at 37 weeks' gestation with a normal pregnancy, which was planned to ECV because of breech presentation. Few minutes after the intramuscular Bricanyl administration prior to the ECV, the patient presented vaginal bleeding and hypotension. Urgent Caesarean Section (CS) was performed and placental abruption was diagnosed.  PA is a rare diagnosis and many risk factors have been reported. This case report might present another potential risk factor associated with PA, namely tocolysis injection. Since early diagnosis of PA is lifesaving and diagnosing of PA can be difficult, this report rightly urges to share the awareness of tocolysis injection as a rare risk factor for placental abruption.

Venue: Constructive Mathematical Analysis
Year: 2019

A summation/integration method for fast summing trigonometric series is presented. The basic idea in this method is to transform the series to an integral with respect to some weight function on \RR_+ and then to approximate such an integral by the appropriate quadrature formulas of Gaussian type. The construction of these quadrature rules, as well as the corresponding orthogonal polynomials on \RR_+ are also considered. Finally, in order to illustrate the efficiency of the presented summation/integration method two numerical examples are included.
