۰۹:۲۵ ZV9 HW2-C.pdf Dept: Civil Eng. Kerbala HW2 3rd Year (C) Ex 4-1: The field capacity and wilting point as depth equivalent of soil are 178mm and 102 mm respectively. PAD-60% Calculate the irrigation interval if the water consumptive use is 4.5 mm/day. Ex 4-2: The specific gravity of the soil is 1.41 percentage of water content by weight at field capacity and wilting point are 15% and 7% respectively. a) calculate the equivalent depth of moisture content for 1.2m root zone and PAD 70% at permanent wilting point, at field capacity and for readily available water b) If the crop consumptive use is 18 m/donum/day, calculate: Irrigation interval in days, field water duty assuming 40% losses during irrigation and amount of added water to irrigate one hectare. Ex4-3: Using Blaney-Criddle formula, calculate the irrigation interval through specific interval of plant growth according to the following data: . Mean air temperature 25 C percentage of day light hour through the month 8.4% Crop…

this module is machine learning 700, please answer all correctly.   Question One       Predicting House Prices using Real Estate Data (25 Marks) 25 Marks A real estate company, UrbanNest Realty, wants to improve its property pricing strategy. Traditional valuation methods often lead to mispricing, affecting revenue and customer satisfaction. The company aims to use machine learning to predict house prices more accurately. Dataset: California Housing Prices from sklearn.datasets (a) Load the dataset and perform basic exploratory data analysis (EDA) by displaying summary statistics, handling missing values, and visualizing key features. (6 Marks) (b) Train a Linear Regression and a Decision Tree Regressor to predict house prices. Evaluate the models using Mean Absolute Error (MAE) and R² Score. (12 Marks) (c) Interpret the model performances and discuss how feature selection or additional preprocessing could improve accuracy. (7 Marks) Question Two       Customer Segmentation using Mall…

Determine the global stiffness matrix of the beam shown in Fig. 3. Assume supports at 1 and 3 are rollers and the support at 2 is a pinned support.  Indicate the degrees of freedom in all the stiffness matrices. EI is constant, w=60kN/m, L1=1.25m and L2=3.75m   please explain how the code numbers for global matrix are determined in detail
