Utilizing VR and Gaze Tracking to Develop AR Solutions for Industrial Maintenance
Venue: CHI
Year: 2020

Augmented reality (AR) presents a variety of possibilities for industrial maintenance. However, the development of real world AR solutions has been limited due to the technological capabilities and uncertainty with respect to safety at deployment. We introduce the approach of using AR simulation in virtual reality (VR) coupled with gaze tracking to enable resource efficient AR development. We tested in field AR guidance and safety awareness features in an iterative development evaluation process with experts from the elevator maintenance industry. We further conducted a survey, utilizing actual gaze data from the evaluation to elicit comments from industry experts on the usefulness of AR simulation and gaze tracking. Our results show the potential of AR within VR approach combined with gaze tracking. With this framework, AR solutions can be iteratively and safely tested without actual implementation, while gaze data provide advanced objective means to evaluate the designed AR content, documentation usage, and safety awareness.
A cluster of the first reported Plasmodium ovale spp. infections in Peru occuring among returning UN peace keepers, a review of epidemiology, prevention and diagnostic challenges in nonendemic regions
Venue: Malaria Journal
Year: 2019

BackgroundPlasmodium ovale curtisi and Plasmodium ovale wallikeri are regarded as less virulent forms of malaria with a geographic distribution including Southeast Asia, Central and West Africa, and is increasingly reported as an infection in returning travellers. A species of malaria that may have delayed or relapsing presentations similar to Plasmodium vivax, the clinical presentation of P. ovale spp. has been described to have prepatent periods of 2 weeks or slightly longer with reports of relapse following primary infection out to 8 9 months. This presentation may be obscured further in the setting of anti malarial exposure, with report of delayed primary infection out to 4 years. Presented is a cluster of 4 imported P. ovale spp. cases in returning Peruvian military personnel assigned to United Nations peace keeping operations in the Central African Republic.Case presentationFrom January to December 2016, Peruvian peace keepers were deployed in support of United Nations (UN) operations in the Central African Republic (CAR) While serving abroad, Navy, Army, and Air Force members experienced 223 episodes of Plasmodium falciparum malaria following interruption of prophylaxis with mefloquine. Diagnosis was made using rapid diagnostics tests (RDTs) and/or smear with no coinfections identified. Cases of malaria were treated with locally procured artemether lumefantrine. Returning to Peru in January 2017, 200 peace keepers were screened via thick and thin smear while on weekly mefloquine prophylaxis with only 1 showing nucleic acid within red blood cells consistent with Plasmodium spp. and 11 reporting syndromes of ill defined somatic complaints. Between a period of 5 days to 11 months post return, 4 cases of P. ovale spp. were diagnosed using smear and polymerase chain reaction (PCR) following febrile complaints. All cases were subsequently treated with chloroquine and primaquine, with cure of clinical disease and documented clearance of parasitaemia.ConclusionThese patients represent the first imported cases in Peru of this species of malaria as well as highlight the challenges in implementing population level prophylaxis in a deployed environment, and the steps for timely diagnosis and management in a non endemic region where risk of introduction for local transmission exists.
Fast room temperature self healing siloxane elastomer for healable stretchable electronics.
Venue: Journal of colloid and interface science
Year: 2020

Siloxane elastomers having simultaneously high stretchability, fast and efficient self healing abilities at room temperature and excellent mechanical properties have broad application prospects in many fields. However, it is still challenging to satisfy this request. In this work, a stretchable, fast self healing siloxane elastomer was successfully synthesized by introducing aromatic disulfides into a siloxane matrix. The resulting siloxane elastomer exhibited a tensile stress of 0.5 MPa, an elongation at break over 1000% and a healing efficiency above 95% at room temperature. The healed siloxane elastomer could recover an elongation at break of 357 15% after healing for only one minute at room temperature. A healing efficiency higher than 90% was achieved even after surface aging or by overlap contact, which was due to the presence of the dynamic disulfide bonds. Furthermore, the elastomer was successfully deployed as the substrate for self healing stretchable electronics. As a proof of concept, stretchable electrode and stretchable strain sensors were produced, and they all showed high stretchability, fast self healing properties at room temperature and high durability and stability, paving the way to promising applications in stretchable and wearable electronics.
Re learning Design: Pedagogical Experiments with STS in Design Studio Courses
Year: 2018

In the last decades, design disciplines have been encountering the social sciences and humanities in inventive modes. These new collaborations entail partial redefinitions of the disciplines involved therein. On the one hand, contemporary strands of social and cultural theory especially in the field of science and technology studies (STS) but also in anthropology have made design much more than a mere research object. On the other hand, design disciplines have incorporated not only social research methods and ethnography, but also the type of conceptual work characteristic of social and cultural theory. This has led to a series of redefinitions of current design practices beyond the 'problem solving' of user centered design, design thinking or co design approaches. In contrast to these current trends, some designers are increasingly describing their tasks as forms of 'problem making'
Item analysis of multiple choice questions of undergraduate pharmacology examinations in a medical college in Belagavi, Karnataka, India
Year: 2018

Multiple choice questions (MCQs) are a common method of assessment of medical students. The quality of MCQs is determined by three parameters such as difficulty index (DIF I) discrimination index (DI) and Distractor efficiency (DE) Item analysis is a valuable yet relatively simple procedure, performed after the examination that provides information regarding the reliability and validity of a test item. The objective of this study was to perform an item analysis of MCQs for testing their validity parameters.  50 items consisting of 150 distractors were selected from the formative exams. A correct response to an item was awarded one mark with no negative marking for incorrect response. Each item was analysed for three parameters such as DIF I, DI, and DE.  A total of 50 items consisting of 150 Distractor s were analysed. DIF I of 31 (62% items were in the acceptable range (DIF I= 30 70% and 30 had 'good to excellent' (DI >0.25) 10 (20% items were too easy and 9 (18% items were too difficult (DIF I <30% There were 4 items with 6 non functional Distractor s (NFDs) while the rest 46 items did not have any NFDs.  Item analysis is a valuable tool as it helps us to retain the valuable MCQs and discard or modify the items which are not useful. It also helps in increasing our skills in test construction and identifies the specific areas of course content which need greater emphasis or clarity.
Co circulation of three camel coronavirus species and recombination of MERS CoVs in Saudi Arabia
Venue: Science
Year: 2016

Coronaviruses in the Middle East Middle East respiratory syndrome coronavirus (MERS CoV) causes severe acute respiratory illness and kills about a third of people infected. The virus is common in dromedary camels, which can be a source of human infections. In a survey for MERSCoV in over 1300 Saudi Arabian camels, Sabir et al. found that dromedaries share three coronavirus species with humans. Diverse MERS lineages in camels have caused human infections, which suggests that transfer among host species occurs quite easily. Haagmans et al. made a MERS CoV vaccine for use in camels, using poxvirus as a vehicle. The vaccine significantly reduced virus excretion, which should help reduce the potential for transmission to humans, and conferred cross immunity to camelpox infections. Science, this issue p. 81, p. 77 Several camel coronaviruses occur in the Middle East, and a recombinant lineage is linked to the recent human outbreaks of MERS. Outbreaks of Middle East respiratory syndrome (MERS) raise questions about the prevalence and evolution of the MERS coronavirus (CoV) in its animal reservoir. Our surveillance in Saudi Arabia in 2014 and 2015 showed that viruses of the MERS CoV species and a human CoV 229E related lineage co circulated at high prevalence, with frequent co infections in the upper respiratory tract of dromedary camels. viruses of the betacoronavirus 1 species, we found that dromedary camels share three CoV species with humans. Several MERS CoV lineages were present in camels, including a recombinant lineage that has been dominant since December 2014 and that subsequently led to the human outbreaks in 2015. Camels therefore serve as an important reservoir for the maintenance and diversification of the MERS CoVs and are the source of human infections with this virus.
Organizational Climate and Culture: Reflections on the History of the Constructs in the Journal of Applied Psychology
Venue: The Journal of applied psychology
Year: 2017

We review the literature on organizational climate and culture paying specific attention to articles published in the Journal of Applied Psychology (JAP) since its first volume in 1917. The article traces the history of the 2 constructs though JAP has been far more important for climate than culture research. We distinguish 4 main periods: the pre 1971 era, with pioneering work on exploring conceptualization and operationalizations of the climate construct; the 1971 1985 era, with foundational work on aggregation issues, outcome focused climates (on safety and service) and early writings on culture; the 1986 1999 era, characterized by solidification of a focused climate approach to understanding organizational processes (justice, discrimination) and outcomes (safety, service) and the beginnings of survey approaches to culture; and the 2000 2014 era, characterized by multilevel work on climate, climate strength, demonstrated validity for a climate approach to outcomes and processes, and the relationship between leadership and climate and culture. We summarize and comment on the major theory and research achievements in each period, showing trends observed in the literature and how JAP has contributed greatly to moving research on these constructs, especially climate, forward. We also recommend directions for future research given the current state of knowledge.
A Context Encoder For Audio Inpainting
Venue: IEEE/ACM Transactions on Audio, Speech, and Language Processing
Year: 2019

In this article, we study the ability of deep neural networks (DNNs) to restore missing audio content based on its context, i.e. inpaint audio gaps. We focus on a condition which has not received much attention yet: gaps in the range of tens of milliseconds. We propose a DNN structure that is provided with the signal surrounding the gap in the form of time frequency (TF) coefficients. Two DNNs with either complex valued TF coefficient output or magnitude TF coefficient output were studied by separately training them on inpainting two types of audio signals (music and musical instruments) having 64 ms long gaps. The magnitude DNN outperformed the complex valued DNN in terms of signal to noise ratios and objective difference grades. Although, for instruments, a reference inpainting obtained through linear predictive coding performed better in both metrics, it performed worse than the magnitude DNN for music. This demonstrates the potential of the magnitude DNN, in particular for inpainting signals that are more complex than single instrument sounds.
Image Aesthetic Assessment Based on Perception Consistency
Venue: PRCV
Year: 2019

Automatically assessing the aesthetic quality of images that is consistent with humans is a challenging task. Previous works based on Convolution Neural Network (CNN) lacks of perception consistency in two aspects. First, they mainly extract features from the entire image without distinguishing between the foreground and background. Second, they classify images with highly compressed semantic feature. In this paper, we proposed a visual perception network (VP Net) to support perception consistency learning. It was designed as a double subnet network which can learn from subject region feature and multi level features. In addition, a subject region search algorithm was proposed to find out a composed of multiple subject regions. Experimental results on a large scale aesthetic dataset (AVA) have demonstrated the superiority of our approach.
Carcass Yield, Non Carcass Parts, Internal Organs and Meat Quality Characteristics of Karayaka Male Lambs with Different Birth Weight Fed Free Choice Feeding
Year: 2017

In order to investigate the changes in meat quality characteristics and some serum metabolites as well as carcass yield, non carcass parts, internal organs of lambs as influenced by birth weight (BtW) and feeding system (FS) 28 Karayaka male lambs (150 days of age) obtained from four comparable groups that consisted of seven replicates according to a 2 x 2 factorial arrangement for 2 BtW (low, 4.1 0.06 kg and high, 5.0 0.09 kg) and 2 FS (total mixed ration, TMR and free choice feeding, FCF) were used. After weaning (90 days of age) lambs with low BtW and high BtW were fed individually a TMR ad libitum or fed on the same ingredients (FCF) as that of TMR. The TMR was consisted of 80% of a compound feed and 20% of roughage based on a dry matter basis (140 g crude protein and 10.7 ME MJ/kg) The carcass weight and yield of lambs were not affected by the BtW, FS and BtWxFS interaction. The slaughter body weight, cold carcass weight and yield of FCF fed lambs were higher than those of TMR fed animals. The pH45 and shear force of semitendinosus muscle decreased and increased by the FCF systems, respectively. These results showed that BtW of lambs did not affect the studied parameter and that feeding system created more differences in terms of some parameters due to the fact that the FCF lead to improvement in carcass and some meat quality traits.
Essential oils as insect repellent agents in food packaging: a review
Venue: European Food Research and Technology
Year: 2020

Active food packaging is currently of high demand in food industries to provide protections to food. Food packaging is not only used to store and protect food from the environment, but also to provide functional values with the incorporation of active agent. Essential oils (EOs) extracted from a variety of plants represent active ingredients of natural origin which provide numerous benefits to food, aromatherapy, pharmaceutical, and food packaging industries due to their functional properties. Numerous researches have been carried out in developing active food packaging such as insect repellent packaging containing essential oils. Insect repellent packaging could create safety measures by repelling insect from exterior environment or the inhibition of larvae from food within. In this paper, different application of EOs on different types of food packaging, applications, processing methods, migration of active compounds and performance of insect repellency are reviewed. Future perspectives and applications of insect repellence using safe, natural and more effective strategies are also discussed. EOs as the active insect repellent agents in food packaging offer great opportunities to protect the quality of food. Some important factors such as legislative concerns (e.g. toxicity test, migration of active substances from packaging materials) economics, and further study on the release period of active agent to the environment should be considered to successfully implement insect repellent agents in food packaging.
Compressed sensing based MR image reconstruction from multiple partial K space scans
Venue: 2011 IEEE Workshop on Signal Processing Systems (SiPS)
Year: 2011

In Magnetic Resonance Imaging (MRI) signal averaging is an established technique for reducing white Gaussian noise or motion artifacts. Acquiring multiple scans for signal averaging is time consuming. To reduce the data acquisition time, Compressed Sensing (CS) based techniques advocate partial scanning of the K space only. Instead of using averaging techniques in conjunction with CS based reconstruction, this work proposes a novel formulation that produces extremely accurate reconstruction results. Our method gives the same reconstruction accuracy at 50% K space sampling as does the conventional signal averaging of the full K space.
Fabrication and characterization of a novel polyvinyl alcohol graphene oxide sodium alginate nanocomposite hydrogel blended PES nanofiltration membrane for improved water purification
Year: 2020

Novel asymmetric microporous polyethersulfone (PES)/polyvinyl alcohol graphene oxide sodium alginate (PVA GO NaAlg) nanocomposite hydrogel (HG) blended nanofiltration membranes with preferable characteristics were fabricated with the phase inversion induced by immersion precipitation technique. The hydrophilic PVA GO NaAlg nanocomposite hydrogel with carboxyl, hydroxyl, carboxylate ions and epoxy groups was in situ formed by chemical crosslinking in presence of the saturated boric acid and CaCl2 curing solution and characterized with SEM, XRD and FTIR analyses. Distinct quantities of the nanocomposite hydrogel were applied in the PES doping solutions for modifying membrane characteristics and the results were compared by pristine PES and PES/polyvinyl pyrrolidone (PVP) membranes. The prepared membranes characterization was performed using SEM, AFM, ATR FTIR, water contact angle, overall porosity and mean pore radius measurement. Pure water flux, antifouling ability and dye rejection properties were also studied. By HG concentrations enhancement up to 1 wt% the permeability of the membranes were improved and also antifouling ability of membranes were improved. The hydrogel blended membranes showed Lanasol blue 3R dye rejection more than 83% Results of comparing PVP additive with HG indicated that the HG could increase hydrophilic property of membrane and result in permeability and antifouling ability improvement. On the other hand, the PVP additive has effective efficiency in membranes porosity and permeability improvement. Hence, the membrane by 1 wt% PVP and 1 wt% HG was fabricated for studying the coupling effect of these two additives, which indicated better solution flux and antifouling properties.
Sepsis Patient Outcome Prediction Using Machine Learning
Year: 2019

Sepsis is a life threatening response of the body to infection that often leads to death. In Brazil, hundreds of thousands of deaths occur every year, with a mortality rate higher than the world average. In this context, it is important to develop tools for decision support and training of healthcare professionals. This work discusses a modelling for sepsis that may be instrumental for achieving such goals. Machine learning is used to train a model for prognosis of outcome of septic patients. The inputs of the model include information about the patient sepsis, previous clinical records and treatment variables. The results show that high accuracy can be achieved and that the network is able to really map patients in two highly distinct groups of risk (survival and fatal outcome) under certain conditions.
