Time Table Scheduling Using MATLAB & Graph Theory Techniques []

Time Table Scheduling Using MATLAB & Graph Theory Techniques One of the most common academic scheduling issues in any educational system is the time table generation. The presence of vast numbers of students and offered courses makes it difficult to schedule lectures in a limited epoch of time. An appropriate schedule can be designed by utilizing different resources like courses, students and rooms in a way to evade conflicts by fulfilling special types of constraints. The educational institute time table should avoid such conflicts, like no two or more courses for the identical student should be scheduled at the same period of time. There is a much need of an effective and accurate timetable to the performance of any educational institute. Graph theory techniques with MATLAB is one decent approach which can deal with timetable scheduling problem. In this work, a systemic model has been framed by applying graph vertex coloring approach for generating educational timetable with the help of a course matrix generated from given data. Here course credit list and subject combinations have been used as input data. This input data was linked considering the students who follow each subject combination. MATLAB was used to generate the adjacency course matrix from linked data and to plot the particular graph using the course matrix. Welch Powell algorithm can be used to find the chromatic number of the particular graph using MATLAB implementation. Based on the course matrix, the system would detect the colliding subjects and assign the colors to the nodes, which represent the subjects. Two courses are said to collide each other if they are adjacent. Adjacent subjects could not be assigned the same color. Thus, optimal solutions for such problem may be found by determining minimal colorings for the corresponding graph. Also, the time table scheduling problem has been categorized as a NP-hard problem. That means it is unlikely to find a fast algorithm to solve this problem, and to find a solution to such problem we need to consider all the possible solutions, and then choose the best one. Keywords: adjacency course matrix, Welch Powell algorithm, chromatic number.

Prayer/“prayer” duality real nature and conceptualization: the connection to Covid-19 []

The purpose of this article is reinforcing the understanding of the real nature of prayer/“prayer” duality, justifying its conceptualization, and connecting this concept to Covid-19. Although the relation between prayer and language has been questioned, there is no reason to unrelate these two concepts. Prayer concept explains “a deeper layer” in the cognitive system. Let us remember the concept of prayer related to language, is just a research option. The other alternative is going back to traditional generative grammar from “Syntactic Structures” (Chomsky, 1957) on, as mentioned from the very beginning of this research line.


The study of under water depth of lake and ocean floors and accurate data for production of nautical chart is the main objective of bathymetric survey. This research work was conducted to investigate changes in the topography of a section of the Sombeiro river adjoining the Degema hulk jetty. Data acquisition was done using satellite imagery, tidal observation and reduction, depth sounding with echo sounder and GPS. Initial processing performed on observed bathymetric data includes tidal correction on instantaneous depth and sorting with HYPACK 2008 software. Further processing was done using ArcGIS 10.0 software. The processed depth was analyzed and presented in form of charts and graphs. From the analysis conducted, there is an accreted sediment volume and perhaps could have been influenced by the adjoining tributaries of the sombiero river. For further studies, the need to investigate the stretch of the sombiero river starting from Obuama through Degema to Abonnema is recommended.

Data Mining Water Table []

Preservation of groundwater is very important for the development of agro-based countries. The majority of irrigation is dependent on it. There are several sources of groundwater systems including water pumps and bore-well that utilize groundwater to mitigate the immediate requirement. These sources are named as “water-points”. It is of vital importance to collect data about the water points from a particular region and also its operating conditions. Water infrastructure plays an important role in the development of agriculture and irrigation systems in various geographical regions. The data for this paper is taken from “Taarifa waterpoints dashboard, which aggregates data from the Tanzania Ministry of Water” (Cited: Caskey, Brandon, Jacob Gable, and William Lewis. "Predicting Functionality of Tanzanian Waterpoints." Proceedings of Student Research and Creative Inquiry Day 6 ) Our focus is to do a comparative study of various machine learning techniques to find out the best model suitable to determine the status of the operating water points and willingness to help in building the best water infrastructure.

Stepwells: Understanding their growing impact on Contemporary Arts and practices in India []

‘Heritage is, after all, about interpreting history for the future and re-reading our past through our contemporary values’. (https://globalheritagefund.org/2018/04/24/placemaking-heart-heritage-conservation/) This statement ties in with the current views that the arts community has today. There is a growing interest in the heritage sector, for both its tangible and intangible concepts in the contemporary arts. There are quite a few tangible and intangible heritage that have been cultivated and adapted into the arts and one of which is the stepwell. Stepwells were primarily built for the utilitarian purpose of collecting and harvesting rainwater. They were structures that served to provide water to arid regions in India, primarily Gujarat and Rajasthan. With time their religious popularity increased and hence their architectural features became aesthetically elaborate and spiritual. This paper will address their genesis and influence on arts and consequently on their current status as ‘more than just a religious totem’.

Change of Entropy and Equilibrium Condition []

The Clausius inequality relation of entropy change and Boltzmann expression of entropy are used to derive three statistical distributions, partition function as well as Helmholtz energy, Gibbs energy and chemical potential as equilibrium properties of the system. The chemical potential of all particles of the system are equal irrespective of their occupied energy level. The derivation of statistical distributions avoids the calculus of variation and Lagrange undetermined multipliers which are unavoidable to derive partition function and three statistical distributions using the statistical thermodynamics.

Prediction of cyber attacks using data science techniques []

Cyber-attacks end to destroy or virulently manipulate a computing terrain or structure, as well as disrupt data integrity or crack all information. This poses a threat to the organization, maybe performing in data loss. The data from device detectors is collected as big data, which has a wealth of information that can be utilized for targeted assaults. Although being methodologies, models, and algorithms have given the foundation for cyber-attack prognostications, new models and algorithms grounded on data representations other than task-specific ways are needed. Its on-linear information processing armature, on the other hand, can be customized to learn indispensable data representations of network business in order to classify different types of network attacks. In this study, we treat cyber-attack vaticination as a bracket issue, in which networking sectors must use machine literacy approaches to read the type of network assault from a given dataset. The supervised machine learning fashion( SMLT) is used to assay a dataset in order to capture multiple pieces of information, similar as variable identification, uni-variate analysis, bi-variate andmulti-variate analysis, missing value treatments, and so on. A comparison of machine literacy algorithms was conducted to estimate which algorithm is the stylish accurate at prognosticating the types of cyber-attacks. DOS Attack, R2L Attack, U2R Attack, and inquiry Attack are the four types of attacks we classify. The findings reveal that the suggested machine literacy algorithm fashion has the stylish delicacy with entropy computation, perfection, recall, F1 Score, perceptivity, particularity, and entropy.
