What is c#
What is c#shwet18 C# is an object-oriented programming language that was introduced by Microsoft in 2000. It allows developers to build reusable components for a variety of application types. C# code is compiled into an intermediate language (IL) that is then just-in-time compiled and executed by the .NET Common Language Runtime (CLR). The CLR handles memory management, garbage collection, and other services so developers do not have to write that code. Because C# relies on the CLR, it has access to the .NET Framework Class Library which includes tens of thousands of reusable objects. This allows C# to be used for desktop applications, web applications, web services, databases and more.

Programming
Programmingshalsmart12 Computer programming involves writing source code instructions in a language the computer can understand to perform tasks. High-level languages like Java and C# are translated into machine code by compilers or interpreters. There are two main programming approaches - procedural which focuses on ordering blocks of code, and object-oriented which packages data and code together into objects. Object-oriented programming is now the most common approach used in languages like Java, C++ and C#.

Mode-Wise Corridor Level Travel-Time Estimation Using Machine Learning Models
Mode-Wise Corridor Level Travel-Time Estimation Using Machine Learning ModelsJournal of Soft Computing in Civil Engineering This research is oriented towards exploring mode-wise corridor level travel-time estimation using Machine learning techniques such as Artificial Neural Network (ANN) and Support Vector Machine (SVM). Authors have considered buses (equipped with in-vehicle GPS) as the probe vehicles and attempted to calculate the travel-time of other modes such as cars along a stretch of arterial roads. The proposed study considers various influential factors that affect travel time such as road geometry, traffic parameters, location information from the GPS receiver and other spatiotemporal parameters that affect the travel-time. The study used a segment modeling method for segregating the data based on identified bus stop locations. A k-fold cross-validation technique was used for determining the optimum model parameters to be used in the ANN and SVM models. The developed models were tested on a study corridor of 59.48 km stretch in Mumbai, India. The data for this study were collected for a period of five days (Monday-Friday) during the morning peak period (from 8.00 am to 11.00 am). Evaluation scores such as MAPE (mean absolute percentage error), MAD (mean absolute deviation) and RMSE (root mean square error) were used for testing the performance of the models. The MAPE values for ANN and SVM models are 11.65 and 10.78 respectively. The developed model is further statistically validated using the Kolmogorov-Smirnov test. The results obtained from these tests proved that the proposed model is statistically valid.

Design Optimization of Reinforced Concrete Waffle Slab Using Genetic Algorithm
Design Optimization of Reinforced Concrete Waffle Slab Using Genetic AlgorithmJournal of Soft Computing in Civil Engineering This research presents the optimization techniques for reinforced concrete waffle slab design because the EC2 code cannot provide an efficient and optimum design. Waffle slab is mostly used where there is necessity to avoid column interfering the spaces or for a slab with large span or as an aesthetic purpose. Design optimization has been carried out here with MATLAB, using genetic algorithm. The objective function include the overall cost of reinforcement, concrete and formwork while the variables comprise of the depth of the rib including the topping thickness, rib width, and ribs spacing. The optimization constraints are the minimum and maximum areas of steel, flexural moment capacity, shear capacity and the geometry. The optimized cost and slab dimensions are obtained through genetic algorithm in MATLAB. The optimum steel ratio is 2.2% with minimum slab dimensions. The outcomes indicate that the design of reinforced concrete waffle slabs can be effectively carried out using the optimization process of genetic algorithm.
OPTIMIZING DATA INTEROPERABILITY IN AGILE ORGANIZATIONS: INTEGRATING NONAKA’S...
OPTIMIZING DATA INTEROPERABILITY IN AGILE ORGANIZATIONS: INTEGRATING NONAKA’S...ijdmsjournal Agile methodologies have transformed organizational management by prioritizing team autonomy and
iterative learning cycles. However, these approaches often lack structured mechanisms for knowledge
retention and interoperability, leading to fragmented decision-making, information silos, and strategic
misalignment. This study proposes an alternative approach to knowledge management in Agile
environments by integrating Ikujiro Nonaka and Hirotaka Takeuchi’s theory of knowledge creation—
specifically the concept of Ba, a shared space where knowledge is created and validated—with Jürgen
Habermas’s Theory of Communicative Action, which emphasizes deliberation as the foundation for trust
and legitimacy in organizational decision-making. To operationalize this integration, we propose the
Deliberative Permeability Metric (DPM), a diagnostic tool that evaluates knowledge flow and the
deliberative foundation of organizational decisions, and the Communicative Rationality Cycle (CRC), a
structured feedback model that extends the DPM, ensuring long-term adaptability and data governance.
This model was applied at Livelo, a Brazilian loyalty program company, demonstrating that structured
deliberation improves operational efficiency and reduces knowledge fragmentation. The findings indicate
that institutionalizing deliberative processes strengthens knowledge interoperability, fostering a more
resilient and adaptive approach to data governance in complex organizations.
Modeling the Influence of Environmental Factors on Concrete Evaporation Rate
Modeling the Influence of Environmental Factors on Concrete Evaporation RateJournal of Soft Computing in Civil Engineering Newly poured concrete opposing hot and windy conditions is considerably susceptible to plastic shrinkage cracking. Crack-free concrete structures are essential in ensuring high level of durability and functionality as cracks allow harmful instances or water to penetrate in the concrete resulting in structural damages, e.g. reinforcement corrosion or pressure application on the crack sides due to water freezing effect. Among other factors influencing plastic shrinkage, an important one is the concrete surface humidity evaporation rate. The evaporation rate is currently calculated in practice by using a quite complex Nomograph, a process rather tedious, time consuming and prone to inaccuracies. In response to such limitations, three analytical models for estimating the evaporation rate are developed and evaluated in this paper on the basis of the ACI 305R-10 Nomograph for “Hot Weather Concreting”. In this direction, several methods and techniques are employed including curve fitting via Genetic Algorithm optimization and Artificial Neural Networks techniques. The models are developed and tested upon datasets from two different countries and compared to the results of a previous similar study. The outcomes of this study indicate that such models can effectively re-develop the Nomograph output and estimate the concrete evaporation rate with high accuracy compared to typical curve-fitting statistical models or models from the literature. Among the proposed methods, the optimization via Genetic Algorithms, individually applied at each estimation process step, provides the best fitting result.
Physical and Physic-Chemical Based Optimization Methods: A Review
Physical and Physic-Chemical Based Optimization Methods: A ReviewJournal of Soft Computing in Civil Engineering Optimization techniques can be divided to two groups: Traditional or numerical methods and methods based on stochastic. The essential problem of the traditional methods, that by searching the ideal variables are found for the point that differential reaches zero, is staying in local optimum points, can not solving the non-linear non-convex problems with lots of constraints and variables, and needs other complex mathematical operations such as derivative. In order to satisfy the aforementioned problems, the scientists become interested on meta-heuristic optimization techniques, those are classified into two essential kinds, which are single and population-based solutions. The method does not require unique knowledge to the problem. By general knowledge the optimal solution can be achieved. The optimization methods based on population can be divided into 4 classes from inspiration point of view and physical based optimization methods is one of them. Physical based optimization algorithm: that the physical rules are used for updating the solutions are:, Lighting Attachment Procedure Optimization (LAPO), Gravitational Search Algorithm (GSA) Water Evaporation Optimization Algorithm, Multi-Verse Optimizer (MVO), Galaxy-based Search Algorithm (GbSA), Small-World Optimization Algorithm (SWOA), Black Hole (BH) algorithm, Ray Optimization (RO) algorithm, Artificial Chemical Reaction Optimization Algorithm (ACROA), Central Force Optimization (CFO) and Charged System Search (CSS) are some of physical methods. In this paper physical and physic-chemical phenomena based optimization methods are discuss and compare with other optimization methods. Some examples of these methods are shown and results compared with other well known methods. The physical phenomena based methods are shown reasonable results.
