Process Monitoring Using Truncated Gamma Distribution
No full textThe time-between-events idea is commonly used for monitoring high-quality processes. This study aims to monitor the increase and/or decrease in the process mean rapidly using a one-sided exponentially weighted moving average (EWMA) chart for the detection of upward or downward mean shifts using a truncated gamma distribution. The use of the truncation method helps to enhance and improve the sensitivity of the proposed chart. The performance of the proposed chart with known and estimated parameters is analyzed by using the run length properties, including the average run length (ARL) and standard deviation run length (SDRL), through extensive Monte Carlo simulation. The numerical results show that the proposed scheme is more sensitive than the existing ones. Finally, the chart is implemented in real-world situations to highlight the significance of the proposed chart
Prognostic factors associated with disease progression in parkinson's disease
No full textThis thesis examined the factors correlated with rapid and benign progression of disease in a group of 1452 Parkinson’s disease (PD) patients. The data were collected in a movement disorders clinic at the Royal University Hospital, University of Saskatchewan run by Dr. Alex Rajput and Dr. Ali Rajput. This data is a clinical dataset of PD patients collected from 1970 through to February, 2005. This was a retrospective cases-only study, with anticipated analytical follow-up if any correlations were detected between progression type of PD and the many independent variables available in the dataset. Rapid progression was defined as those subjects who reached Hoehn and Yahr stage 3 within three years or H&Y stage 4 or 5 within five years. Subjects who remained in Hoehn and Yahr stage 1 or 2, ten years after onset of disease, were defined as having benign progression. The study analyzed demographic and clinical findings at first visit to this clinic associated with rapid and benign progression of PD. Analysis revealed that, at first clinic visit, benign progression was positively associated with disease duration (OR=1.41; 95% CI 1.27, 1.57), male sex (OR=3.23; 95% CI 1.70, 6.16), and current smoking habit (OR=2.33; 95% CI 0.67, 8.11). Benign progression was negatively associated with older age of onset (OR=0.36; 95% CI 0.25, 0.50), past history of smoking (OR=0.46; 95% CI 0.24, 0.89), current or past use of levodopa (OR=0.45; 95% CI 0.21, 0.98), and mild to severe rigidity (OR=0.43; 95% CI 0.23, 0.80). Analysis also revealed that, at first clinic visit, rapid progression was positively associated with older age of onset (OR=2.45; 95% CI 1.80, 3.33) and mild to severe rigidity (OR=1.73; 95% CI 1.02, 2.94). Rapid progression was negatively associated with disease duration (OR=0.52; 95% CI 0.44, 0.62), male sex (OR=0.58; CI 0.35, 0.95), and mild to severe resting tremor (OR=0.47; CI 0.28, 0.77). The results of this study indicate that age of onset, disease duration, male sex, and rigidity are good potential predictors of disease progression in PD because they have opposite associations with rapid and benign progression. History of levodopa use was negatively associated with benign progression and as such may be good indicator of non-benign progression. Although previous studies found no predictive value for smoking history, the current study reported a unique association between smoking history and benign progression. Past smoking history was negatively associated with benign progression. While there was a positive association with current smoking history, the result was not statistically significant. Resting tremor was negatively associated with rapid progression and as such may be a good indicator of non-rapid progression. Disease characteristics collected at first clinic visit are useful in predicting the course of progression of PD. With more rapid progression of PD closer and more frequent follow-up of patients may be necessary
A New Hotplug Coded Caching Scheme Using PDAs
No full textPublisher Copyright: © 2024 IEEE.In the original coded caching model introduced by Maddah-Ali and Niesen in 2014, the server starts broadcasting only after it receives demands from all the users. So, all the users must be active during the delivery phase. In this work, we consider a coded caching model called hotplug coded caching in which some of the users are offline during the delivery phase. This model was first introduced by Ma and Tuninetti ('On Coded Caching Systems with Offline Users,' 2022 IEEE International Symposium on Information Theory). The concept of Hotplug Placement Delivery Arrays (HpPDAs) for the hotplug coded caching systems was introduced in ('Improved Hotplug Caching Schemes Using PDAs and t-Designs,' arXiv:2311.02856, 2024), in which the authors have constructed HpPDAs from t-designs. This work provides a new hotplug coded caching scheme from the existing HpPDAs. The performance comparison of the proposed scheme with the existing schemes is presented. When applied for HpPDAs from t-designs, our scheme outperforms the baseline scheme by Ma and Tuninetti, and the Improved t-scheme by Rajput and Rajan in some memory segments.Peer reviewe
Blocking Probabilities in WDM Switching Networks using Overflow Analysis Method
No full textWavelength Division Multiplexed switching networks are considered as an important candidate for the future transport networks. As the size of network increases conventional methods used in teletraffic theory to model these networks become computationally difficult to handle as the state space grows exponentially. In this research we have applied overflow analysis to model these networks. Our results show that moment analyses using equivalent random theory (ERT) results in accurate approximations for the modeling of WDM switching networks
Green synthesis of silver Nanoparticle using Carica Papaya and study there Biochemical Application
No full textAbstract: The nanopartical offer several advantages over other conventional drug delivery systems. Nanoparticles have gained importance in technological advancements due to their modifiable physical, chemical and biological properties with improved performance over their bulk foils. Nanoparticles can simply move in the body due to their small size and reach very complex organs through divers routes. The high stability, controlled drug release makes nanoparticles the most suitable drug delivery system. The study of different methods of synthesis of nanoparticles is essential to obtain desired nanoparticle with specific sizes and shapes. They are suitable candidates for various marketable and local application, which include imaging, catalysis medical application and environmental application.
Keywords: Nanopartical, bulk foil, divers routes.

Implementing Constructivist Pedagogical Model in Dynamic Distance Learning Framework
No full textThe objective of this paper is to develop an educational framework, using data mining technologies, with the help of dynamic web technologies that will be used by teachers to organize the course contents on the web according to existing infrastructure, experience, needs, reorganizing it later on if necessary, depending upon the performance of students. The approach to organizing the lecture contents is based on adaptive learning theory, incorporating a Problem Based Learning (PBL) strategy. Presently, course syllabus and handouts on web sites provided to the student are static in nature. Once distributed, these documents cannot be changed or modified, and lack depth. When course materials are placed on the web, students can select a topic in the course outline and look at the description of a topic, and required reading assignments. Instructors can easily change schedules in these on-line documents and inform the students via e-mail. Students can also submit assignments, projects and take-home exams electronically. A course home page comprises a syllabus, assignments, projects and exams, readings and references, class presentation charts and student handouts. Students on a course are mostly assessed based on questions such as Why, How, What, etc. In this way, a student can be graded and ranked, which in turn provides the feedback to the student for future improvement and challenges. Most such web sites are implemented on the theory of constructivism. Constructivists propose that the construction for new knowledge starts from one’s observations of events through previous experiences. Hence, learning is the integration of new knowledge and behaviours into a framework and subsequently recalling relevant events in the appropriate situation. This theory is also applied in our educational framework
The Indian Army in Europe, 1914–1918
No full textIn January 1915, a wounded Punjabi Rajput soldier, recovering from injuries sustained on the Western Front, wrote a letter home from a hospital in Britain to a relative in India. ‘This is not war,’ he said, ‘it is the ending of the world. This is just such a war as was related in the Mahabharata about our forefathers’. The author of these words-a Hindu of warrior caste-had been serving, under British leadership, with the Indian Corps in France. Indian troops had arrived in France in late September 1914. They were to fi ght at all the main actions of the British Expeditionary Force in 1914-1915. The Indians fought at the First Battle of Ypres; they were prominent in the British attack at Neuve Chapelle in March 1915; one Indian division was badly mauled at the Second Battle of Ypres in April 1915; and Indian troops went into the attack on the first day of the Battle of Loos in September 1915. The two Indian infantry divisions that had been serving in France were withdrawn at the close of 1915. Two Indian cavalry divisions stayed on in France until March 1918, when they were transferred to the Middle East. We can learn a great deal about the Indian soldiers’ experiences in France because much of their correspondence has survived-preserved as translated extracts attached to the reports of the British military censorship
