Sliding mode control of discrete-time weakly coupled systems
No full textSliding mode control is a form of variable structure control which is a powerful tool to cope with external disturbances and uncertainty. There are many applications of sliding mode control of weakly coupled system to absorption columns, catalytic crackers, chemical plants, chemical reactors, helicopters, satellites, flexible beams, cold-rolling mills, power systems, electrical circuits, computer/communication networks, etc. In this thesis, the problem of sliding mode control for systems, which are composed of two weakly coupled subsystems, is addressed. This thesis presents several methods to apply sliding mode control to linear discretetime weakly-coupled systems and di fferent approaches to decouple the sub-systems. The application of Utkin and Young's sliding mode control method on discrete-time weakly-coupled systems is studied in detail which is then compared with other control algorithms while emphasizing the importance of the decoupling technique in each case. It also presents the possibility of integrating two or more control strategies for a single system; one for each sub-system, depending upon the respective requirements and constraints. In this thesis, the eff ectiveness of the proposed methods is demonstrated through theory and simulation results.M.S.Includes bibliographical referencesIncludes vitaby Prashanth Kumar Gopal
The Moderating Effect of Perceived Social Support on Stress and Depression among University Students
No full textBackground and objectives: The omnipresence of stress and depression among university students is a cause for concern, as it can have adverse consequences on all aspects of their life. Understanding the role of social support as a protective factor within this context, may well be vital to the enhancement of overall wellbeing among students. The main aim of the present study was to examine the moderating effect of perceived social support on the relationship between stress and depression. Methods: A cross-sectional survey was conducted to garner data from 254 university students for hierarchical multiple regression and structural equation modeling analysis. Results: Firstly, the present study replicated the frequently reported positive relationship between stress and depression. Secondly, an inverse association between social support and depression was also depicted. Finally, the results also supported an interaction between perceived social support and stress in predicting depression among students. Conclusion: In sum, the results of the current study may well augment our understanding of the role of perceived social support in combating stress and depression among students, and thereby convey important implications for intervention strategies tailored to this demographic
Author recognition using Locality Sensitive Hashing & Alergia (Stochastic Finite Automata)
No full textIn today’s world data grows very fast. It is difficult to answer questions like 1) Is the content completely written by this author, 2) Did he get few sentences or pages from another author, 3) Is there any way to identify actual author. There are many plagiarism software’s available in the market which identify duplicate content. It doesn’t understand writing pattern involved. There is always a necessity to make an effort to find the original author. Locality sensitive hashing is one such standard for applying hashing to recognize authors writing pattern
Grit and Self-Efficacy on Growth Mindset- A Review Based Analysis
No full textPurpose: Grit signifies a student's competence that endures after stumbling academic blocks. The trait Grit is closely identified with mindset. Students who believe that their shortcomings result from their fixed mental models, find no use nor reason to attempt again. Individuals with such rigid attitudes are believed to have a fixed mindset. On the contrary, students with a growth mindset are more likely to be resilient and have more grit. On the contrary, individuals who are mentally tough and strong are likely to be considered to have a growth mindset. According to previous research, grit is a question of nature and nurture. People need to build a growth attitude in order to become grittier.
Design/Methodology/Approach: More than 100 research papers, articles, and journals were reviewed systematically to identify gaps, identify conflicts in previous studies, and for the purpose of foundation of knowledge on current topic. A systematic review of literature uses a meticulous and transparent methodology for research synthesis, with the aim of evaluating and, where feasible, diminishing bias in the findings. This review is based on careful and systematic scrutinization of the above-mentioned keywords and their combinations thereof. Electronic databases like Google Scholar, Research gate, Academia, Srinivas Publication and Mendeley/Elsevier with open access journals were perused.
Results/ Findings: The relevant reviews indicate that people with a higher level of a growth mindset exhibit an equally high level of self-efficacy than pupils who had a more rigid perspective. Several literatures suggest that grit is associated with improved participation and better performance in a school environment. Students with a fixed mindset have a strong notion that their innate intelligence is limited preventing them from reaching their desired goals. This results in a hopeless ‘giving up’ attitude with a deep-rooted fear of failure. Whereas a growth mindset person marches forward with confidence. Their thoughts and beliefs are controlled by them. They understand that every person is brilliant in their own way which can be built, changed, and developed over time with the necessary components of will and effort. Few studies highlight different intervention models to improve fixed mindset of students. Few other studies suggest that practitioners could find a difference in the increase of grit with effective and committed goal settings which eventually would lead to an increased level of mindset in the right direction.
Originality/Value: This study is a prequel for the original study on grit, self-efficacy, and mindset modification for the professional success of Industrial Training Institute Students. This intervention-based study has been recommended by few previous studies. In all originality, the experimental study would largely impact the young adults, their cognition and non-cognitive behavior with a developed growth mindset.

Disparate Psychological Emergencies and its Variegated Clinical Management Directives
No full textPurpose: Tension is generated for everyone concerned when psychological emergencies like severe sensorimotor excitement or suicidal behavior occur in places other than psychological facilities like regular clinics, emergency departments, or clinicians' private offices. These should always be managed right away since they could be fatal. As a tool for their quick as well as efficient care, including the key exhibiting symptoms, multiple diagnoses options, and therapeutic choices for the major categories of mental crises have been included in this paper so that the general population as well as the clinicians of all other specialties other than psychology specialists, can understand the common psychological emergencies and its proper treatment.
Objective: There is relatively little reliable data on the frequency of mental crises in routine as well as community practice, in accidents and emergencies in healthcare facilities, or with patients treated by urgent healthcare units. Given the realities of modern healthcare institutions and the public's general hostility to psychological issues of any kind, we shouldn't be surprised that the first therapy for psychological illnesses often doesn't really occur in specialized mental institutions. When there are accidents or crises, people with psychiatric diseases who don't want to be stigmatized commonly resort to ordinary hospital systems since they are commonly both accessible and always open. Understanding different psychological emergencies, as well as associated therapeutic care procedures, is crucial. So the very basic and important objective of this paper is to gain knowledge about some common psychological emergencies and their treatment.
Design/Methodology/Approach: Data from a number of reputable, official sources and journal articles were used to produce this clinical research output. Certain data from the emergency department have also been used to develop this study in order to make it more precise and scientific in type. The credibility of the publication has also been guaranteed by expert evaluations from neuropsychologists, general psychologists, doctors, and researchers who are conducting studies in the field.
Findings/ Result: Due to the increasing incidence of drug and alcohol abuse, depression, and other critical illnesses, more people are visiting the critical healthcare department. The occurrence of psychological events in non-psychological contexts, such as typical clinics and physicians' homes, and subsequent care is poorly documented by the few observational trials and scant precise information that are currently available. The available research emphasizes the need for improvements in both mental emergency evaluation and care. The treatment of this type of issue entails high expectations of the therapist's personality and conduct in addition to the required therapeutic competence. If the patient approaches the emergency department voluntarily or the family takes him/her to the clinic at the earliest, all the psychological problems can be treated with at most results.
Originality and value: A thorough attempt has been launched to shed some light on the issue of several frequent psychological emergencies and their appropriate diagnosis in the emergency room using only certain basic evaluation techniques and without wasting much time. Several evaluation tools and criteria have also been given for the convenience of various clinicians with varying levels of experience.

Updated area function analysis for nano indentation of micro fibers
No full textKevlar has a remarkable combination of high strength, high modulus, toughness and thermal stability compared to many other organic fibers. These impressive properties are due to their molecular structure, developed during their production process which is based on liquid crystal technology, as the rigid molecular chains form a mesophase in solution. Modeling of the high-performance ballistic fabric has gradually shifted from the continuum and yarn length scales to the sub-yarn length scale which enabled establishment of the relationships between the fabric penetration resistance and various fiber-level phenomena such as fiber-fiber friction, fiber twist, and transverse properties of the fibers. An instrumented indentation method was established in this thesis work to accurately measure the local elastic-plastic material properties of a single fiber. As indentation theory assumes that the indent is being placed on a semi-infinite flat surface, general area function cannot predict accurate projected area on a circular specimen. The indentations on cylindrical surface require modified equations to determine the area function and subsequently, the hardness and reduced modulus. The Oliver-Pharr instrumented indentation data analysis method is followed for the calculation of area function of the indenter geometry through the simulation of the known properties of the material. This new area function calculation method is compared with the geometry correction method by Quinn McAllister and John W. Gillespie, Jr to calculate the elastic modulus of the fiber in transverse direction. In addition, Compliance contributions are attributed to the lack of constraint due to the finite geometry of a curved fiber surface. This compliance contribution is accounted by using a proposed area correction to capture the geometry of the curved fiber-probe contact. Implementation of these corrections to experimental indentation curves results in accurate measurements of the fiber elastic modulus.M.S.Includes bibliographical referencesby Prashanth Turl
