Perceived emotional intelligence family environment and locus of control as predictors of well-being among adolescents
Adolescence is unparalleled in a person s life as the most important period in his/her newlinepersonality development. It is perceived that well-being is the keystone to an individual s wholesome being. In the past, well-being was discussed in the context of the absence of distress symptoms that include depression, anxiety, divergent behaviors and other disorders. In more recent times it has received a positive note where well-being is widely identified with the positive qualities, which each individual possesses to lead a healthy and happy life. Fifty percent of the mental health disorders begin during the onset of adolescence. There is a need to focus on adolescent well-being in India which has the world s largest adolescent population. Based on the related theories and studies, certain variables like perceived emotional intelligence, family environment and locus of control were selected for the study. The main aim of the study boiled down to two points, to investigate the relationship between perceived emotional intelligence, family environment, locus of control and well-being among adolescents and to research and explore the extent to which newlineperceived emotional intelligence, family environment, locus of control and the newlinedemographic variables (gender, type of family and religion) would contribute towards newlinethe development of well-being among adolescents. Accordingly psychological tools newlinewere adopted. The sample consisted of 903 students studying in plus one and plus two newline(age 16-18 years) Government aided and unaided state-syllabus schools in Parur, subdistrict of Ernakulum, Kerala. Among them 450 adolescents were from nuclear families and 453 others were from joint families. Gender-wise the sample constituted of 413 adolescents males and 490 females. A quantitative survey method design and newlinepurposive sampling method was adopted in the study. Spearman s coefficient of correlation was used to measure the relationship between the variables. -
Assessing Opportunities and Constraints of Community Engagement in Tourism Development at Hampi
Community Based Tourism will create a momentous milestone in improving the participation level of local communities in the arena of Heritage tourism as well as all the various branches of the travel and expedition industry. Whose heritage is being preserved, by whom, and for what purposes? (Shepherd 2006). This study particularly gives due emphasis on evaluating the level of participation from the resident???s part by assessing various development strategies offered by the respective authorities. The study also tries to address all the possible streams where the community can easily thrive and it also addresses the major obstacles which restricts their entry, indicating an inclusive approach towards community participation through community based tourism (CBT). Lack of cooperation among stakeholders was identified as challenges of CBT, (Tamir 2015). Tourism market of Hampi is developing year by year but the standard of living of the underprivileged community is always remains the same without any improvement and this is the core problem mentioned in the study. Quantitative research technique was used for the study with the help of a structured questionnaire which was used for collecting data. The collected data was analyzed with the help of quantitative data analysis software, SPSS. This research tries to bring out the various reasons behind the low level of community involvement in tourism industry with relevant evidence from the analyzed data. The study indicates the hopelessness of the community towards the major development strategies forwarded by the authorities especially Hampi Master Plan. It also addresses the poor level of education and lack of information about the potential of tourism employability and its scope in the field of community development. A unique relic of medieval commerce and religious faith into a lifeless ruin, (John and Michell2012) this study pinpoints the inefficiency of the tourism boards and poor functioning of other responsible authorities too. It VII also invokes the possibilities of promoting Agro-Tourism along with the existing Heritage tourism. There is enough scope for further study in the light of execution of CBT model as well as assessing the scope of Agro tourism in Hampi. This suggestion is propounded mainly because of the structural phase of the economy that is more than 70% of the working population is involved in agriculture and its allied sectors. There is a noticeable gap between the expectations of the local residents and what they are actually receiving from the authorities moreover, these entire gaps may hamper the idea of inclusive approach. If effective training and regular awareness creation program is initiated by the responsible authorities, it will create a better platform for inclusive approach. -

Detecting various biomarkers in the health industry and the biomedical sector has been newlinesignificant due to their crucial role in diagnosing, assessing, exposing, and treating disorders. This work reports electrochemical sensors for detecting biomarkers using different modifications (2D materials and nanomaterials) on carbon fiber paper electrode-based (CFPE) sensors. Adopting these modifications on the CFPE electrode greatly intensified the oxidation and reduction of peak current values. The physio-chemical characterizations of the designed electrodes were examined employing Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Electron Diffraction X-ray (EDX), X-Rayv Photoelectron spectroscopy (XPS), Fourier Transform Infrared Spectroscopy (FTIR), and Raman Spectroscopy. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) newlineassisted in optimizing the electrochemical properties via Nyquist plots, sensing performance, scan rate effect, and pH effect. Both electro-activity studies and Nyquist plots confirmed the enhancement in the electroanalytical performance of the fabricated electrodes. Real sample newlinestudies were successfully analyzed using developed electrodes, producing good recovery newlinepercentages. Overall, all the works conducted have been established to be facile and selective, with novelty in the fabrication of ultrasensitive voltammetric-based sensors to quantify different biomarkers. -
Design and Implementation of Low Complexity Multiplier-Less Reconfigurable Band Tuning Filter Structure with Sharp Sub-Bands
Digital flter banks are extensively used for communication purposes for channelization. Reconfgurable non-uniform multi-channels with sharp transition widths are necessary for channelization in digital channelizer and spectrum sensing in wireless communication networks. The aim of this research work is to design reconfgurable flter structures featuring non-uniform and sharp transition newlinewidth channels with reduced number of flter coeffcients. The four different flter structures are proposed in this research for achieving low complexity reconfgurable structure for the design of multiple non-uniform sharp transition width arbitrary bandwidth channels. The foundational newlineelement of this research is centered around the design of a prototype flter. This prototype flter serves as a basis for developing various reconfgurable flter structures. Leveraging the prototype newlineflter s bandwidth characteristics, these structures are categorized into two main groups: narrow band prototype flters and wide band prototype flters. The narrow band prototype flter category comprises structures capable of designing a single fnite impulse response flter with a narrow passband characterized by sharp transition widths. In contrast, the wide band prototype flter category includes structures capable of designing a single FIR flter with a wide passband also characterized by sharp transition widths. A novel flter structures are designed with the help of interpolated newlinefnite impulse response, cosine modulation technique, complex exponential modulation technique and frequency response masking techniques. The proposed method is evaluated using MATLAB R2019b, where the linear phase FIR flter coeffcients are computed based on the Parks-McClellan algorithm. The examples are employed to illustrate the effcient operation of the proposed designs. The results point to the fact that the proposed designs have less multiplier complexity than existing cuttingedge techniques. -

A Study on Some Eccentricity Related Problems in Graphs
The concepts related to eccentricity in graphs are explored in this research work. newlineThe eccentric graph Ge of a graph G has the same vertex set as that of G and two newlinevertices in Ge are adjacent if one is the eccentric vertex of the other. The eccentric newlinegraphs of some graph operations are explored, and the iterated eccentric graphs Gek newlineare introduced. The process of inding eccentric graphs, known as eccentrication, is newlinestudied in detail. Graphs that result in a complete graph Kn upon iterative eccentrication are characterized, and the cyclic property of eccentrication is established for various cycle-related graphs. The eccentrication of tree graphs is studied in detail, and a general result on the cyclic property of trees is obtained. A conjecture on the cyclic property of eccentrication for any graph G is made. The ei-signed graph of a graph G, where the edge between vertices u and v receives a sign and#963; = (and#8722;1)|ecc(u)and#8722;ecc(v)|, where ecc(u) is the eccentricity of vertex u, is investigated. General properties of ei-signed graphs, such as homogeneity, consistency, switching, and sign compatibility, are discussed. Properties that behave diferently across various classes of graphs are explored. Finally, the scope of this study is presented, and some open problems in the area are provided. -
A Study on the Emergence of Subaltern Counterpublics in Select Malayalam Dalit Christian Narratives
The research A Study on the Emergence of Subaltern Counterpublics in Select Malayalam Dalit Christian Narratives attempts to put Kerala's vernacular Dalit Christian narratives into the scholarly canvas. As statistics do not provide solid data on the quotidian resistance, the narratives reveal the overt and covert struggles of the Dalit Christians. The study problematises the dominant narrative of the State and the Church and provides a way to articulate their voices and the transition from one religion to another. The primary texts for the study include Paul Chirakkarodes Pulayathara, Nostalgia and Eli Eli, Lama Sabach Thani, T.K.C. Vaduthalas Achante Venthinga Inna! and C Ayyapans Ghost Speech. The current study uses the combined frameworks of narratology, Lacanian psychoanalysis and subaltern counterpublics through the method of narrative analysis. Narrative analysis involves analysing stories or narratives to understand their meanings, experiences and values. The research argues that the Dalit Christian narratives become a testimony of subaltern counterpublics, narratology, and resistance tactics, suggesting a counter- narrative effect. They become treasure houses that carry group memory of community life and history. They are enclaved spaces where unfiltered articulations of marginalisation, abandonment, exploitation, rejection, resistance and empowerment occur. They function as proactive spaces that challenge dominant stereotypes and create an ideologically sound public sphere. Alternative discourse arenas become places of empowerment where subaltern counterpublics emerge, thus transforming the narratives into counter-narratives. The study acknowledges the agency of the Dalit Christian narratives to reform, rethink and reinterpret the form and content of Dalit Christian literature from a subaltern perspective. From an epistemological perspective, the Dalit Christian narratives produce knowledge garnered through analysing and interpreting the primary texts as representative of fusing personal and political resources to create a narrative of resistance and survival. -

A conceptual study on searching techniques used in ontology based search engines /
Search engines play a vital role in finding the relevant information across the web and make it available on the finger tips. But they seemed to be less efficient to understand the relationship between the keywords which had an adverse effect on the results it produced. Semantic search engines ?? only solution to this; is still an unrealized dream due to various underlying issues. Reducing the time taken to search the semantic annotated documents is a highly demanded solution for semantic search engines. This research focuses on a study and improvisation of searching techniques used in semantic search engines keeping time complexity as the major factor. Developing semantic search engines is considered to be a time consuming and tedious process. The reasons attributed to that are ?? It is a mightier task to semantically annotate each and every resource (text and multimedia files) available on the net as the number keeps on increasing in an exponential order per day. -
A Study on certain chromatic parameters and polynomials of graphs
In graph theory, graph colouring pertains to the assignment of colours to the elements of a graph such as vertices, edges and faces. Because of the theoretical and practical implications of graph colourings in real-life situations, it is an adequate mathematical model for a wide range of applications such as network analysis, genomic, routing, newlineoptimisation techniques, digital networks and so forth.Motivated by various problems in chemical graph theory and information networks, chromatic topological indices were introduced in recent literature [81], opening ample and vibrant research area in graph theory.In the research reported in this thesis,the vertices of a graph are assigned with colours subject to certain conditions and manipulating their colour codes, a rich research area on chromatic topological indices and different chromatic polynomials are established. newlineAfter mentioning some fundamental terminologies, the study handles the notions of chromatic topological indices and chromatic irregularity indices. A detailed discussion of their upper and lower bounds concerning certain colouring conditions is carried out in this thesis. Chromatic topological indices of a wide variety of graph classes such as wheels, double wheels, helm graphs, closed helm graphs, flower graphs, sunflower graphs and blossom graphs are considered and investigated. The chromatic topological indices of certain derived graphs such as Mycielskian of paths and cycles are also included. Equitable chromatic topological and irregularity indices and injective chromatic topological and irregularity indices are defined and their values are determined for a handful of graph classes. As an indirect analogue to chromatic polynomials in the literature, the notion of chromatic Zagreb polynomials and chromatic irregularity polynomials are being introduced and the same is determined and discussed for paths, cycles and certain cycle related graph classes. -
An investigative approach to hard machining of inconel 718 with coated carbide tool
Super alloys sustain good strength at high temperature and pressure conditions. Such
materials have high demand in Aerospace industry, Marine industry, and Nuclear power plants. They have a great demand in Nuclear and Aerospace applications because of it retain its properties at temperature over 700 °C. Machinability of nickel based super - alloys is extremely poor, mainly due to their low thermal conductivity, build up edge and self-hardening, which leads to high dynamic cutting forces. They are difficult to machine because of its high shear strength, work hardening and precipitation hardening. High abrasive particles in its microstructure and tendency forming chip to weld to tool and form Built Up Edge (BUE) make it more difficult to machine. Friction between tool and material and its low thermal conductivity results in high temperature generation. They have Nickel (Ni), Chromium (Cr), Ferrous (Fe) or Cobalt (Co) as base contains. Small amount of Al, Ti, Nb, Ta, W, Mo added to these alloys to sustain at high temperature. Chromium is important alloying element in order to obtain the hot corrosion resistance property. Due to these factors the tool wear is extremely high and increasing the tool life by minutes is an enormous success. To overcome this situation, various materials have been developed for Inconel 718 machining. Though Ceramic tools, Silicon Carbide whiskers, reinforced alumina tools, carbide tools have been used to machine Inconel 718 but they have failed to produce good surface, better accuracy and minimum tool wear. -
