Reverse Engineering Roadmap to Effective software Design
Year: 2009

The process of duplicating an existing component, subassembly, or product, without the aid of drawings, documentation, or computer model is known as reverse engineering. So reverse engineering is the process of learning the design of an object by studying its implementation. It is the process of discovering the technological principles of a device, object or system through analysis of its structure, function and operation. The role of reverse engineering in software evolution is important. It provides the means for recapturing lost information, restructuring complex systems or transforming old systems to a new, more maintainable and better architecture. Reverse engineering software helps researchers to examine the strength of systems and identify their weaknesses in terms of performance, security, and interoperability. The goal of reverse engineering itself is the improved documentation of how the original product works by uncovering the underlying design. In this paper various reverse engineering tools are discussed which help in developing software design better by the use of existing
SERUM CALCIUM, MAGNESIUM AND POTASSIUM IN ACUTE DIARRHOEA PATIENTS COMING TO PRAVARA RURAL HOSPITAL
Year: 2018

Diarrhoea is a leading cause of morbidity and mortality across all age groups and regions of the world. Electrolyte imbalances are very common with the severity of acute diarrhoea. The aim of present study was to study the Serum Calcium, Magnesium and Potassium levels in patients of acute diarrhea.  This was a descriptive longitudinal study carried out in Department of Medicine, of PRH, Loni. Patients of diagnosed of acute diarrhea of age 18 and above of either gender willing to participate by giving written informed consent were included in the study. Patients with history of electrolyte abnormalities, history of chronic gastroenteritis, irritable bowel disease, congestive cardiac failure, liver cirrhosis, renal diseases, history of any disease deranging serum electrolyte levels and those on diuretics or any drugs which causes electrolyte imbalance were excluded from the study. Patients included in the study were subjected to demographic profile and serum electrolytes before and after treatment.  100 patients were included in the study. Male patients were more in number (56) as compared to female patients. Signs of dehydration were present in 70 patients. The patients suffering from hypokalemia, hyponatremia, hypocalcaemia and hypomagnesaemia were 23, 35, 78 and 84 respectively. Thus electrolyte imbalances are quite common in patients suffering from acute diarrhea. On comparing the serum Calcium, Magnesium and Sodium levels before and after treatment, statistically significant difference was seen. It was not significant for serum Potassium levels.  Electrolyte imbalances are quite common in patients suffering from acute diarrhea. The serum electrolytes of patients suffering from acute diarrhea should be routinely examined to rule out electrolyte abnormalities and prompt treatment.  Acute diarrhea; Adults; Serum electrolytes.
Factors Related to the Prevention and Management of Pressure Ulcers
Venue: Computers, informatics, nursing CIN
Year: 2012

Pressure ulcers (a type of skin failure) have served as an indicator of care quality. The purpose of this study was to utilize data mining techniques as a means of identifying risk factors related to different stages of pressure ulcers to demonstrate how this means of analysis might be used as a vehicle to guide improved care quality. Data were obtained from a Web based incident reporting system at a regional hospital in Taiwan. A total of 4301 cases dating from March 2005 to May 2009 were collected. For data cleaning purposes, data within 3 SDs were kept for further analysis. Data mining techniques were applied to identify the predictors, and a logistic regression analysis was used for result comparison purposes. The results revealed that sacral ulcer was the most prevalent, and most ulcers were in stage I, followed by stages II to IV. Five predictors were identified including hemoglobin, weight, sex, height, and use of repositioning sheet. The study concluded that nurses could use data mining technique to identify predictors to assist in guiding ulcer interventions such as those based on a patient's demographic profile and application of a repositioning sheet to prevent ulcer occurrence to minimize harm.
Time and Memory Efficient 3D Point Cloud Classification
Venue: 2019 16th International Bhurban Conference on Applied Sciences and Technology (IBCAST)
Year: 2019

Recent advancement in real time 3D scanning has upraised the need to maximally crunch the 3D data in minimum possible time. PointNet is a modern end to end deep learning architecture which directly utilizes point cloud without transforming it to regular formats for object classification, part segmentation and scene semantic parsing. In this paper, we have proposed a novel set of hyper parameters for PointNet which significantly reduced the size of network while achieving the same accuracy in 3D object classification as of the original network. This can enable the PointNet to be deployed on less resourceful hardware. The modified PointNet utilizes 16.5 Million less parameters (weights) and 5.2 Million lesser memory units. Moreover, through ample experiments, we demonstrate that our proposed configuration is highly efficient in terms of training and testing time.
The effect of hatch angle rotation on parts manufactured using selective laser melting
Venue: Rapid Prototyping Journal
Year: 2019

This paper aims to present an investigation into the variation of scan vector hatch rotation strategies in selective laser melting (SLM) focussing on how it effects density, surface roughness, tensile strength and residual stress.  First the optimum angle of hatch vector rotation is proposed by analysing the effect of different increment angles on distribution of scan vectors. Sectioning methods are then used to determine the effect that the chosen strategies have on the density of the parts. The top surface roughness was analysed using optical metrology, and the tensile properties were determined using uni axial tensile testing. Finally, a novel multi support deflection geometry was used to quantify the effects of rotation angles on residual stress.  The results of this research showed that the hatch rotation angle had little effect on the density, top surface roughness and strength of the parts. The greatest residual stress deflection was measured parallel to unidirectional scan vectors. The use of hatch rotations other than alternating 90deg showed little benefit in lowering the magnitude of residual stresses. However, the use of rotation angles with a good suitability measure distributes stresses in all directions more evenly for certain part geometries.  All samples produced in this work were made from commercially pure titanium, therefore care must be taken when applying these results to other materials.  This paper serves to increase the understanding of SLM scanning strategies and their effect on the properties of the material.
Economic sentiment as a driver for household financial behavior
Venue: Journal of Behavioral and Experimental Economics
Year: 2019

The study focused on investigating influence of economic sentiments on household financial decisions. A group of Polish households participated simultaneously in a longitudinal study on financial behavior and a consumer tendency survey. Combination of responses from the two surveys was used to investigate a link between economic situation assessment and household financial decisions. With the use of latent class modeling five distinct patterns of saving behavior and six distinct patterns of borrowing behavior were identified among respondents. Patterns in both these domains were confirmed as stable in time. Subsequently, with the use of individual data, a link between indicators from the consumer tendency survey and the evolution of household financial behavior in the domains of borrowing and savings was established. Consumer confidence stimulated debt for durables and mortgages but reduced debt uptake for unexpected expenditures or consumption purposes. Lower consumer confidence increased only likelihood of saving for consumption, confirming the precautionary motive of saving. Multi purpose and home renovation savings both correlated positively with consumer confidence.
Pseudo Immersive Real Time Display of 3D Scenes on Mobile Devices
Venue: 2011 International Conference on 3D Imaging, Modeling, Processing, Visualization and Transmission
Year: 2011

The display of complex 3D scenes in real time on mobile devices is difficult due to the insufficient data throughput and a relatively weak graphics performance. Hence, we propose a client server system, where the processing of the complex scene is performed on a server and the resulting data is streamed to the mobile device. In order to cope with low transmission bit rates, the server sends new data only with a frame rate of about 2 Hz. However, instead of sending plain frame buffers, the server decomposes the scene geometry represented by the current view's depth profile into a small set of textured polygons. This processing does not require the knowledge of objects or structures in the scene, i.e. the output of Time of flight cameras can be handled as well. The 2.5D representation of the current frame allows the mobile device to render plausibly distorted views of the scene at high frame rates as long as the viewing position does not change too much before the next frame arrives from the server. In order to further augment the visual experience, we use the mobile device's built in camera or gyroscope to detect the spatial relation between the user's face and the device, so that the camera view can be adapted accordingly. This produces a pseudo immersive visual effect. Besides designing the overall system with a render server, 3D display client, and real time face/pose detection, our main technical contribution is a highly efficient algorithm that decomposes a frame buffer with per pixel depth and normal information into a small set of planar regions which can be textured with the current frame. This representation is simple enough for real time display on today's mobile devices.

Porous collagen hydroxyapatite scaffolds with mesenchymal stem cells for bone regeneration.
Venue: The Journal of oral implantology
Year: 2015

Current bone grafting materials have significant limitations for repairing maxillofacial and dentoalveolar bone deficiencies. An ideal bone tissue engineering construct is still lacking. The purpose of the present study was first to synthesize and develop a collagen hydroxyapatite (Col HA) composite through controlled in situ mineralization on type I collagen fibrils with nanometer sized apatite crystals, and then evaluate their biologic properties by culturing with mouse and human mesenchymal stem cells (MSCs) We synthesized Col HA scaffolds with different Col:HA ratios. Mouse C3H10T1/2 MSCs and human periodontal ligament stem cells (hPDSCs) were cultured with scaffolds for cell proliferation and biocompatibility assays. We found that the porous Col HA composites have good biocompatibility and biomimetic properties. The Col HA composites with ratios 80:20 and 50:50 composites supported the attachments and proliferations of mouse MSCs and hPDSCs. These findings indicate that Col HA composite complexes have strong potentials for bone tissue regeneration.

A Call for Prudent Choice of Subword Merge Operations in Neural Machine Translation
Venue: MTSummit
Year: 2019

Most neural machine translation systems are built upon subword units extracted by methods such as Byte Pair Encoding (BPE) or wordpiece. However, the choice of number of merge operations is generally made by following existing recipes. In this paper, we conduct a systematic exploration of different BPE merge operations to understand how it interacts with the model architecture, the strategy to build vocabularies and the language pair. Our exploration could provide guidance for selecting proper BPE configurations in the future. Most prominently: we show that for LSTM based architectures, it is necessary to experiment with a wide range of different BPE operations as there is no typical optimal BPE configuration, whereas for Transformer architectures, smaller BPE size tends to be a typically optimal choice. We urge the community to make prudent choices with subword merge operations, as our experiments indicate that a sub optimal BPE configuration alone could easily reduce the system performance by 3 4 BLEU points.
UoB at SemEval 2020 Task 12: Boosting BERT with Corpus Level Information
Venue: SEMEVAL
Year: 2020

Pre trained language model word representation, such as BERT, have been extremely successful in several Natural Language Processing tasks significantly improving on the state of the art. This can largely be attributed to their ability to better capture semantic information contained within a sentence. Several tasks, however, can benefit from information available at a corpus level, such as Term Frequency Inverse Document Frequency (TF IDF) In this work we test the effectiveness of integrating this information with BERT on the task of identifying abuse on social media and show that integrating this information with BERT does indeed significantly improve performance. We participate in Sub Task A (abuse detection) wherein we achieve a score within two points of the top performing team and in Sub Task B (target detection) wherein we are ranked 4 of the 44 participating teams.

Venue: Journal of chromatography. B, Analytical technologies in the biomedical and life sciences
Year: 2012

In recent years, ionic liquids (ILs) as green and designer solvents, have accelerated research in analytical chemistry. This review highlights some of the unique properties of ILs and provides an overview of the preparation and application of IL or IL based materials to extract bioactive compounds in plants. IL or IL based materials in conjunction with liquid liquid extraction (LLE) ultrasonic assisted extraction (UAE) microwave assisted extraction (MAE) high performance liquid chromatography (HPLC) and solid phase extraction (SPE) analytical technologies etc. have been applied successfully to the extraction or separation of bioactive compounds from plants. This paper reviews the available data and references to examine the advantages of IL and IL based materials in these applications. In addition, the main target compounds reviewed in this paper are bioactive compounds with multiple therapeutic effects and pharmacological activities. Based on the importance of the targets, this paper reviews the applications of ILs, IL based materials or co working with analytical technologies. The exploitation of new applications of ILs on the extraction of bioactive compounds from plant samples is expected to increase.
Age and geographic dependence of Zika virus infection during the outbreak on Yap island, 2007.
Venue: Mathematical biosciences and engineering MBE
Year: 2020

Intensive surveillance of Zika virus infection conducted on Yap Island has provided crucial information on the epidemiological characteristics of the virus, but the rate of infection and medical attendance stratified by age and geographical location of the epidemic have yet to be fully clarified. In the present study, we reanalyzed surveillance data reported in a previous study. Likelihood based Bayesian inference was used to gauge the age and geographically dependent force of infection and age dependent reporting rate, with unobservable variables imputed by the data augmentation method. The inferred age dependent component of the force of infection was suggested to be up to 3 4 times higher among older adults than among children. The age dependent reporting rate ranged from 0.7% (5 9 years old) to 3.3% (50 54 years old) The proportion of serologically confirmed cases among total probable or confirmed cases was estimated to be 44.9% The cumulative incidence of infection varied by municipality: Median values were over 80% in multiple locations (Gagil, Tomil, and Weloy) but relatively low values (below 50% were derived in other locations. However, the possibility of a comparably high incidence of infection was not excluded even in municipalities with the lowest estimates. The results suggested a high degree of heterogeneity in the Yap epidemic. The force of infection and reporting rate were higher among older age groups, and this discrepancy implied that the demographic patterns were remarkably different between all infected and medically attended individuals. A higher reporting rate may have reflected more severe clinical presentation among adults. The symptomatic ratio in dengue cases is known to correlate with age, and our findings presumably indicate a similar tendency in Zika virus disease.
Etude des repercussions d'un entrainement des fonctions executives sur les mecanismes de la lecture chez des enfants dyslexiques de CM2
Year: 2013

De nombreuses competences sont requises pour acceder a l'apprentissage de la lecture dont les fonctions executives. De recentes investigations ont mis en exergue l'existence de liens entre le developpement du langage ecrit et les mecanismes de lecture, particulierement le decodage et la fluence en lecture, et des fonctions executives specifiques l'inhibition et la flexibilite. Partant du postulat qu'un entrainement specifique des fonctions d'inhibition et de flexibilite serait susceptible d'ameliorer le dechiffrement et la vitesse de lecture, nous avons propose dans notre etude, d'evaluer l'effet d'une stimulation de la flexibilite et de l'inhibition chez des enfants dyslexiques entre 10 et 11 ans. Les resultats de notre etude montrent dans un premier temps que notre prise en charge a permis d'ameliorer significativement les processus de flexibilite et d'inhibition. De plus, nous pouvons souligner l'augmentation significative des competences de decodage de mots et de vitesse de lecture. A l'issue de notre etude, nous concluons a l'importance d'une prise en charge des fonctions executives dans la dyslexie.

Cloud Based Task Scheduling Using Fuzzy C Means and Linear Programming Approach
Year: 2015

Cloud computing is a latest technology that deals with on demand, online distribution of computing resources and services within managed environment on pay per use scenario.  In the proposed system, cloud resources are scheduled by using linear programming as an optimization technique along with Fuzzy C Means (FCM) as a clustering technique. Cloud user submits the batch of tasks (images for processing) through smart phone to a cloud service provider. Cloud service provider schedules these tasks among the number of resources (smart phones and processors) using FCM and linear programming. The proposed system schedules these tasks in such a way that it requires minimum cost under the time constraint given by submitter. The results of proposed scheduling strategy are compared with the results obtained by First Come First Served (FCFS) scheduling.
HI 21cm Cosmology and the Bi spectrum: Closure Diagnostics in Massively Redundant Interferometric Arrays
Year: 2018

New massively redundant low frequency arrays allow for a novel investigation of closure relations in interferometry. We employ commissioning data from the Hydrogen Epoch of Reionization Array to investigate closure quantities in this densely packed grid array of 14m antennas operating at 100 MHz to 200 MHz. We investigate techniques that utilize closure phase spectra for redundant triads to estimate departures from redundancy for redundant baseline visibilities. We find a median absolute deviation from redundancy in closure phase across the observed frequency range of about 4.5deg. This value translates into a non redundancy per visibility phase of about 2.6deg, using prototype electronics. The median absolute deviations from redundancy decrease with longer baselines. We show that closure phase spectra can be used to identify ill behaved antennas in the array, independent of calibration. We investigate the temporal behavior of closure spectra. The Allan variance increases after a one minute stride time, due to passage of the sky through the primary beam of the transit telescope. However, the closure spectra repeat to well within the noise per measurement at corresponding local sidereal times (LST) from day to day. In future papers in this series we will develop the technique of using closure phase spectra in the search for the HI 21cm signal from cosmic reionization.
