An Ideal Approach for Detection and Prevention of Phishing Attacks

Narendra. M. Shekokar, Chaitali Shah, Mrunal Mahajan, Shruti Rachh
2015 Procedia Computer Science  
Phishing is a treacherous attempt to embezzle personal information such as bank account details, credit card information, social security number, employment details, and online shopping account passwords and so on from internet users. Phishing, or stealing of sensitive information on the web, has dealt a major blow to Internet security in recent times. These attacks use spurious emails or websites designed to fool users into divulging personal financial data by emulating the trusted brands of

URL-based phishing detection involves extraction of actual URL (to which the website is actually directed) and the visual URL (which is visible to the user). LinkGuard Algorithm is used to analyze the two URLs and finally depending on the result produced by the algorithm the procedure proceeds to the next phase. If phishing is not detected or Phishing possibility is predicted in URL-based detection, the algorithm proceeds to the visual similarity based detection. A novel technique to visually compare a suspicious page with the legitimate one is presented.

Resumable online index rebuild in SQL server

Panagiotis Antonopoulos, Hanuma Kodavalla, Alex Tran, Nitish Upreti, Chaitali Shah, Mirek Sztajno
2017 Proceedings of the VLDB Endowment  
Azure SQL Database and the upcoming release of SQL Server enhance Online Index Rebuild to provide fault-tolerance and allow index rebuild operations to resume after a system failure or a userinitiated pause. SQL Server is the first commercial DBMS to support pause and resume functionality for index rebuilds. This is achieved by splitting the operation into incremental units of work and persisting the required state so that it can be resumed later with minimal loss of progress. At the same time,
more » ... the proposed technology minimizes the log space required for the operation to succeed, making it possible to rebuild large indexes using only a small, constant amount of log space. These capabilities are critical to guarantee the reliability of these operations in an environment where a) the database sizes are increasing at a much faster pace compared to the available hardware, b) system failures are frequent in Cloud architectures using commodity hardware, c) software upgrades and other maintenance tasks are automatically handled by the Cloud platforms, introducing further unexpected failures for the users and d) most modern applications need to be available 24/7 and have very tight maintenance windows. This paper describes the design of "Resumable Online Index Rebuild" and discusses how this technology can be extended to cover more schema management operations in the future.

A top-down design methodology using virtual platforms for concept development

Mohit Shah, Brian Mears, Chaitali Chakrabarti, Andreas Spanias
2012 Thirteenth International Symposium on Quality Electronic Design (ISQED)  
Virtual platforms are widely used for system-level modeling, design and simulation. In this paper, we propose a virtual platform-based, top-down, system-level design methodology for developing and testing hardware/software right from the concept level and even before the architecture is finalized. The methodology is based on using tools such as QEMU, SystemC and TLM2.0 that starts with a functional, high-level description of the system and gradually refines the intricate architectural details.

The system under consideration involves the design of a low-power wearable audio recorder, an Android application for user interface and a server for audio analysis. A virtual system consisting of three instances of QEMU and other tools was created to demonstrate the concept and to test this approach. Finally, we describe a suite of tools useful for quickly validating concepts and creating virtual platforms for early hardware/software codesign.

In-utero Diagnosis of Double Encephalocele - Imaging Features and Review of Literature

Chaitali Kantilal Shah, Roland Y Lee, Sunil Jeph
2021 Journal of Radiology Case Reports  
Encephalocele is protrusion of brain parenchyma through a defect in the cranium. It is classified into various types based on the defect location: sincipital (fronto-ethmoidal), basal (trans-sphenoidal, spheno-ethmoidal, trans-ethmoidal, and spheno-orbital), occipital and parietal. Double encephaloceles are very rare with only a handful of cases reported in the literature and most of these cases involved either occipital or sub-occipital region. All, except one, cases of double encephaloceles

ROLE OF MULTIDETECTOR CT UROGRAPHY IN EVALUATING PATIENTS WITH HAEMATURIA
English

Varsha Rathi, Swenil Shah, Chaitali Nimbalkar, Kalyani Patankar
2016 Journal of Evolution of Medical and Dental Sciences  
Haematuria is one of the commonest manifestation of urinary tract pathologies and requires thorough diagnostic workup. MDCT urography with its faster speed and multiplanar capabilities has become the investigation of choice in such cases. OBJECTIVES Our study was done with the aims of assessing the role of CT Urography in detecting the entire spectrum of urinary tract diseases causing haematuria and also to establish whether this single investigation suffices in directing the right management

MATERIALS AND METHODS This prospective study of 105 patients presenting with haematuria was done at a tertiary care government hospital at Nagpur over a period of two years. Two phase acquisition protocol (Split Bolus technique) with saline distension was done in the majority of cases. Separate cortico-medullary phase images were acquired in cases of renal neoplasms for their better characterization. Images were viewed in axial as well as with 3D reformatted coronal planes. RESULTS Split bolus MDCT Urography with saline distension provided at least 50% opacification of urinary tract in about 94.8%. Major causes of haematuria in our study were urolithiasis (25.7%), Urothelial tract and bladder neoplasms (23.8%) followed by renal neoplasms (16.2%). Developmental anomalies, infections and trauma were some other aetiologies. The overall sensitivity for upper urinary tract evaluation was 100%, while that for lower urinary tract was 88.4%. The overall positive predictive value was 97.4% in diagnosing haematuria by MDCT Urography. CONCLUSIONS CT Urography is highly accurate in evaluation of haematuria and definitely has potential to be one stop shop in evaluation of patients with haematuria. With the use of properly tailored protocols, the issue of radiation exposure can be addressed.

A speech emotion recognition framework based on latent Dirichlet allocation: Algorithm and FPGA implementation

Mohit Shah, Lifeng Miao, Chaitali Chakrabarti, Andreas Spanias
2013 2013 IEEE International Conference on Acoustics, Speech and Signal Processing  
In this paper, we present a speech-based emotion recognition framework based on a latent Dirichlet allocation model. This method assumes that incoming speech frames are conditionally independent and exchangeable. While this leads to a loss of temporal structure, it is able to capture significant statistical information between frames. In contrast, a hidden Markov model-based approach captures the temporal structure in speech. Using the German emotional speech database EMO-DB for evaluation, we

We map the proposed algorithm onto an FPGA platform and show that emotions in a speech utterance of duration 1.5s can be identified in 1.8ms, while utilizing 70% of the resources. This further demonstrates the suitability of our approach for real-time applications on hand-held devices.

Unis D. Nadar, Pareshkumar A. Thakkar, Chaitali Shah
2017 International Journal of Contemporary Pediatrics  
A premature infant is deprived of in-utero sensory experiences which are essential for normal brain development and rather is exposed to unusual sensory stimuli in the Neonatal Intensive Care Units (NICU) that pose risk to the developing brain in terms of adverse neurodevelopmental outcomes. The objective of this study was to study and compare the effect of specific physiotherapy intervention with multisensory stimulation on neurobehavioral outcome and weight gain in preterm infants.

Exclusion criteria were major congenital anomalies, inability to undergo intervention (any fracture) or perinatal asphyxia. Methods: Eligible infants were randomly allocated into one of the two groups. Group A was offered multisensory stimulation: Auditory, Tactile, Visual and Vestibular (ATVV). Group B received Specific Physiotherapy Intervention (SPI) in form of kinesthetic exercises, oil massage and oral stimulation. The outcome was studied before and after intervention. Appropriate statistical tests were applied. Results: Both the groups had better suck co-ordination and improvement on neurobehavioral scale following intervention when compared to pre-intervention status (P<0.0001). When both groups were compared, SPI group had better sucking coordination than ATVV group, improvement in neurobehavioral scale was similar in either group.Conclusions: In preterm infants, Specific Physiotherapy Interventions are more effective in improving suck co-ordination, has better weight gain and are equally effective in improving neurobehavioral outcome compared to multisensory stimulation.
