Optimization of Ketene Production Using Computer Simulated Experimental Design [ ]


The Box-Behnken Design was applied with Response Surface Methodology to investigate the influence of four process variables (Temperature, reaction volume, pressure and Acetone flow rate) on the production of Ketene. The percentage conversion of Acetone was used to measure the response of the influence of the variables on the production of Ketene. The results were analyzed with ANOVA and a second order polynomial was used to predict the effect of the process variables on the percentage Acetone conversion. Results show that temperature has the highest effect on the pyrolysis process. The percentage conversion of Acetone was shown to have a direct relationship with temperature, pressure and reactor volume and an inverse relationship with flowrate. Multi-objective optimization study showed that the optimum condition for acetone conversion was a temperature of 992.2oC, a pressure of 46.2 bar, a flowrate of 21kg/h and a reactor volume of 9.98m3 with a desirability of 1.

Development of a Remote Timing and Monitoring System for GSM Base Station Generators[ ]


Global System for Mobile Communication (GSM) base stations encounters several challenges when trying to provide power to run their equipment. Generators are used as backup power supply in some stations while other stations rely completely on these generators to run the station. The system in the base station requires proper generators synchronization. GSM operators usually find it difficult to time and monitor the state of power supply at the base stations in remote locations, leading to poor quality of services for subscribers if there are any power related issues.

Deep Learning Based Multiple Object Tracking for Facial Images Using Hybrid Neuro Fuzzy Network[ ]


In the present study we present a deep learning based multiple object tracking for facial images using hybrid approach towards countering the problem of partial occlusion in face recognition scenario. The partial occlusion can be caused by various objects such as scarfs, sunglasses etc., and its effects are confounding in the performances of the recognition rates. The advantage that the adopted pre-processing algorithm poses before face recognition steps is to eliminate the distortions due to the variance in light illumination field at the given instance when the facial image is recorded or captured. The framework tends to mathematically model the curvature and other essential features of the face such as micro-expression and the curves of the facial regions.

GH-AODV ROUTING TECHNIQUES TO DETECT AND PREVENT GRAY HOLE ATTACK IN MANET[ ]


One of the most critical problems in MANETs is the security vulnerabilities of the routing protocols. A set of nodes may be compromised in such a way that it may not be possible to detect their malicious behavior easily. Such nodes can generate new routing messages to advertise non- existent links, provide incorrect link state information, and flood other nodes with routing traffic, thus inflicting Byzantine failure in the network.

Forbush Decrease correlated to Geomagnetic storm and Interplanetary magnetic field[ ]


In this present study, we find a correlation between cosmic ray intensity (CRI) and geomagnetic activity i.e. geomagnetic storm (GSs) Dst=-50 nT and interplanetary magnetic field (IMF) for three consecutive solar cycles (SC) from (1986-2016). We found that the variation between CRI and GSs for most of the year showed similar behavior. The peak depression for CRI found on occurrence day of GSs. We have additionally found that CRI depends reciprocally on IMF as a result of the IMF applies force on the charged particle that comes with Coronal mass ejections (CMEs) and drives the CRI.

Impact of emotional labour on burnout among university females teacher: work- family conflict as a mediator in the public sector of Azad Kashmir [ ]


Organizationally desired display of emotions is the need of today’s organization both in private and public sectors. However, display of emotions or emotional labor and its impact on burnout with work family conflict as Mediator have been an understudied area in public sector. Therefore, this research examines the impact of emotional labor on burnout and with work family conflict as Mediator. The findings of our study suggest that emotional labor has a significant positive impact on burnout and with work family conflict consistent with the earlier research. In a sample of 476 married, female universities teachers, with at least one child living at home, results showed that was positively associated with emotional burnout and depersonalization. The results also showed that work–family conflict mediated the relationship between emotional labor and burnout. However, no moderation effect of work–family on the burnout relationship was found. The results are discussed with respect to the general literature on the stress–strain relation and work–family conflict. We have used affective event theory and conservation of resource theory to build our model. Practical and managerial implication of the study are also discussed.

The haematological presentations and mechanisms of thrombosis, the role of anti-coagulation prophylaxis, the management of coagulopathy as well as management of patients with COVID-19 disease and pre-existing bleeding disorders[ ]


Severe COVID-19 infection obviously manifests hypercoagulability in its early stages and later could transform to hemorrhage. The DIC form in COVID-19 has unique features including frequent normal platelet counts, low anti-thrombin levels and hyperfibrinogenemia with progression to hyperfibrinolysis. A severe inflammatory response, originating in the alveoli, triggers a dysfunctional cascade of inflammatory thrombosis in the pulmonary vasculature, leading to a state of local coagulopathy. Numerous ongoing studies investigating the pathophysiology of the COVID-19 associated coagulopathy may provide mechanistic insights that can direct appropriate interventional strategies. Neutrophil /lymphocyte ratio and peak platelet/lymphocyte ratio may also have prognostic value in determining severe cases.

Psychoanalysis of Hind Swaraj[ ]


In Hind Swaraj Gandhi does not have a systematic social study that could objectively draw its political conclusions from. His was a spiritual answer to the horrors of modern society which he regarded as the biggest omen of 20th century- slavery. A fresh look at Hind Swaraj can then frustrate a pure theoretical approach that either seeks to reveal the foundation of Gandhian philosophy as a way of reducing Gandhi to a formulae or to sharpen one's understanding of the processes which in their present form have produced or sustained modern civilization.

Facial Emotion Detection Using Neural Network[ ]


Human emotions are mental states of feelings that come off spontaneously rather than through conscious effort and are accompanied by physiological changes in facial muscles which imply expressions on the face. Non-verbal communication methods such as facial expressions, eye movement, and gestures are used in many applications of human-computer interaction, which among them facial emotion is widely used because it conveys the emotional states and feelings of persons. Emotion recognition is not an easy task because there is no blueprint distinction between the emotions on the face and also there is a lot of complexity and variability.
