        Computer-Aided Genetic Algorithm Based Multi-Objective Optimization of Laser Trepan Drilling

        Sanjay Kumar,Avanish Kumar Dubey,Arun Kumar Pandey 한국정밀공학회 2013 International Journal of Precision Engineering and Vol. No.

        The laser trepan drilling (LTD) has proven to produce better quality holes in advanced materials as compared with laser percussion drilling (LPD). But due to thermal nature of LTD process, it is rarely possible to completely remove the undesirable effects such as recast layer, heat affected zone and micro cracks. In order to improve the hole quality, these effects are required to be minimized. This research paper presents a computer-aided genetic algorithm-based multi-objective optimization (CGAMO) methodology for simultaneous optimization of multiple quality characteristics. The optimization results of the software CGAMO has been tested and validated by the published literature. Further, CGAMO has been used to simultaneously optimize the recast layer thickness (RLT) at entrance and exit in LTD of nickel based superalloy sheet. The predicted results show minimization of 99.82% and 85.06% in RLT at entrance and exit, respectively. The effect of significant process parameters on RLT has also been discussed.

      • Poster Session : PS 0128 ; Cardiology : Case Report - An Unusual Association of Mitral Stenosis with Diffuse Systemic Sclerosis

        ( Girish Ramteke ),( Sanjay Dubey ),( Neeraj Dayani ),( Mridulata Prajapati ),( Paridhi Shivde ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

        Introduction: Disorders of collagen tissue are caused by humoral and cellular mediated immune responses mediated by cytokines like TGF ß, TNF a etc. The various disease manifestations include mixed connective tissue diseases, rheumatoid arthritis, sjogren`s syndrome, systemic sclerosis etc. One of the associations is that of cardiac valvesstenotic lesion-though extremely rare. We report one such rare case. Case presentation: 60 year old female presented with a history of tightness of skin, contractures of fingers, inability to open mouth and pitting scars over the tip of digits. There was no history of breathlessness. There is a history of rheumatic heart disease-mitral stenosis-open mitral valvulotomy 7 years ago. On evaluation she had features suggestive of Mauskopf`s facies, microstomia and other features of systemic sclerosis and the ACR criteria suggested systemic sclerosis. Modified Rodnan skin thickness score was 43 out of 51. Her Antiscl-70 antibody was positive and skin biopsy showed dermal sclerosis. HRCT chest showed- septal thickening with ground glass appearance. Though the patient was asymptomatic her echo revealed chordal shortening, cuspal retraction which was an additional feature compared to earlier echo 7 years ago. This association of valvular involvement in systemic sclerosis is an extremely rare association with only 5 cases reported in literature. Conclusion: Association of valve- stenotic has been very rarely associated with collagen disease like systemic sclerosis; though other collagenous tissues of the body are involved cardiac valves are generally spared. With only 5 cases reported in the literature we report one such case of this rare association where in an initially affected and treated mitral valve due to rheumatic heart disease has been now involved due to systemic sclerosis.

      • Analytical Approach for Security of Sensitive Business Database

        Anusha Gupta,Sanjay Kumar Dubey 보안공학연구지원센터 2015 International Journal of Database Theory and Appli Vol.8 No.3

        Sensitive database security is an integral part to meet the company's abeyance. Securing the sensitive data in mixed database environment has increased over the past few years. This paper conducts the literature review about providing solutions to secure all databases. This will help the users to know what all things are required to be protected when they are planning to protect the database. Sometimes in some of the business it requires highest level of security even if the performance is being compromised. So, this paper will help user to choose appropriate security mechanism to for the sensitive database according to their business requirement. A brief view of securing the network, server and operating system is also provided in the present paper. Aim of this research is to provide the security to sensitive data at all the three levels physical security, network security, information security from unauthorized user.

      • E-Voting System with Physical Verification Using OTP Algorithm

        Indrajeet Sharma,Dr. Sanjay Kumar Dubey 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.8

        E Voting system requires strong voter verification. voter verification is achieved by using two factor authentications method i.e. something the voter know that is static code and something the voter has that is one time password. The key benefit of encompassing a mobile handset is that maximum voter previously have mobile headsets, and therefore no need of any additional hardware essentials to be bought, installed, or maintained. This system mainly develops to increase the overall voting percentage and to reduce the overall cost which is used in election.by using this system people who live out of their native place are able to cast the votes. This system manage the user detail, candidate detail, and election related details and provide result efficiently.it provide hassle free voting to the general public

        Is treatment with platelet-rich fibrin better than zinc oxide eugenol in cases of established dry socket for controlling pain, reducing inflammation, and improving wound healing?

        Sam Paul,Rupshikha Choudhury,Nandini Kumari,Sanjay Rastogi,Ashish Sharma,Vikas Singh,Shyamalendu Laskar,Tushar Dubey 대한구강악안면외과학회 2019 대한구강악안면외과학회지 Vol.45 No.2

        Objectives: To appraise the effectiveness of platelet-rich fibrin (PRF) in the management of established dry socket in terms of pain, inflammation, and wound healing. Materials and Methods: Two hundred patients with established alveolar osteitis were studied to determine the efficacy of PRF and zinc oxide eu- genol (ZOE) for pain control, inflammation reduction, and wound healing. Patients were randomly allocated to Group A (PRF) or Group B (ZOE). Patients were examined on the 1st, 3rd, 7th, and 14th postoperative day and evaluated for pain using visual analogue scale scores, inflammation with a gingival index score, and wound healing through a determination of the number of bony walls exposed. Results: Group A showed better results in terms of pain remission, control of inflammation, and wound healing compared to Group B. Results between groups were statistically significant (P<0.05). Conclusion: PRF is a better alternative than ZOE for the effective management of alveolar osteitis.

      • Poster Session : PS 0314 ; Hematology : Acute Psychosis: A Presentation of Cyanocobalamin Defi ciency Megaloblastic Anemia

        ( Anurag Bahekar ),( Girish Bhageshwar Ramteke ),( Sanjay Dubey ),( Amith R ),( Ankit Meshram ),( Amit Agarwal ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

        Mental disturbances due to vitamin B12 deficiency have been reported previously as chief or sole symptoms, occasionally even preceding decrease of cobalamin in serum. Frank psychosis related to vitamin B12 defi ciency is considered very rare and has received little attention. We report a 28 yrs young female presenting with acute psychosis due to cyanocobalamine deficiency which reversed with treatment. Presentation was irrelevant talking, picking of clothes, inability to recognize people for 3 days. No fever, headache, vomiting, weakness, head trauma, drug intake, stressor or addiction. No past major illness, psychiatric illness or memory loss. Pt. had weaknes easy fatigability since 2 years was on vegetarian diet. Bladder bowel habits were regular. Hb 2. 9 gm/dl, thrombocytopenia 1 lakh/cumm, normal leucocytes, MCV-142. 7 fi , smear showed dimorphic picture, pencil cells, tear drop cells, anisopoikilocytosis, hypersegmented neutrophils. Diagnosis of megaloblastic anemia was made. CSF, CT head, electrolytes were normal. B12 level 77. 12 pmol/l (N200-800 pmol/l). Endoscopy- atrophic gastritis. Histology-atrophic gastriris. Antiparietal cell antibody-negative. Patient recovered fully within 3 days therapy with Inj. cyanacobalamin 1000 microgm i. m. with no need of antipsychotics at discharge. Biermer`s disease, also called acquired pernicious anemia, disorder of vitamin B12 absorption characterized by megaloblastic anemia, gastrointestinal symptoms, can lead to neurological abnormalities. Frequent in elderly, less in adults(15%), extremely rare inchildren, adolescents. It is asymptomatic for years, non-specifi c symptoms of anemia, atrophic gastritis. Possible mechanism for psychotic behaviour suggested by Hutto, reported cobalamin and folate participate in synthesis of monoamine neurotransmitters in brain by increasing BH4(tetrahydrobiopterin) synthesis. Treatment:Oral administration of high-dose vitamin B(12) (1-2 mg daily) as effective as intramuscular administration in correcting defi ciency. We recommend consideration be given to B-12 defi ciency as an etiological possibility in some cases of depression, organic psychosis, certain childhood-disorders and dementia.
