Due to the fact that Iraq is one of the most affected countries, the increase in population growth and the detrimental effects of global warming, along with the neighboring countries' exploitation of transboundary rivers, have resulted in severe water resource shortages and detrimental effects on the environment, society, and economy. One of the most significant projects is the Al Khachiya Irrigation Project, which is extended 55 kilometers to the left of the Tigris River in the Iraqi province of Wasit. It serves an area of roughly 55.8 km². We chose three fields A1, A2, and A3 to assess the Al Khachiya Irrigation Project. The C10 Canal, which is 18.9 km in length and designed to pass an estimated 19.5m³/s, is a component of the Al Khachiya Irrigation Project. A few specifically selected performance measures, such as the effectiveness of water application, storage, and distribution, water conveyance, and overall canal efficiency, were used to evaluate the C10 Canal. The C10 Canal is being evaluated using the A2, A3 fields.The average water application efficiency for the A2 and A3 fields, according to the results is 37.09 % and 46.45 % respectively. In other words, farmers utilize more water than is actually needed. Water storage efficiency is 67.94% and 53.13% for fields A2 and A3 respectively, on average. Moreover, the water distribution efficiency is approximately 92.29% for A2 field and 91.05% for A3 field. According to field measurements, the water conveyance efficiency of C10 Canal is 93.62 %, cracks are observed in some lining boards of C10 canal, which affected the convenience efficiency. The overall efficiency of C10 Canal is 35.85%. The results of evaluation showed that more losses of water were caused by inefficient use, longer operating hours, and a lack of knowledge and expertise among farmers regarding water management.

There is a need for more documentation and quantitative data on architectural and cultural objects, especially considering the deteriorating condition of certain historical assets and the required treatments for them. In this circumstance, it is crucial to have metric documentation of the history being investigated in order to comprehensively comprehend the asset and aid engineers and architects in the restoration process. 3D data acquisition technologies, such as the photogrammetric approach, are frequently associated with high costs. Alternatively, it may necessitate a significant investment of both time and effort, prompting users to explore cost-effective solutions that nevertheless allow them to achieve their desired levels of precision. Recently, geomatic equipment and processes have been developed to optimize efficiency and cost-effectiveness in surveying cultural assets. Apple has incorporated a LiDAR sensor into its products, enabling the creation of a three-dimensional representation of objects or locations. This project aims to assess the precision and practicality of this sensor in generating three-dimensional depictions of cultural artifacts. The study explores the capacity of iPhone lidar (IPL) to aid in the conservation of cultural heritage, examines potential barriers and difficulties that may develop, and evaluates its effectiveness in certain areas. To assess the accuracy of each technique, a scan was performed on the case study utilizing Close Range Photogrammetric (CRP) & iPhone 13 pro max, with confirmed artificial targets monitored by Total Station (TS). The results indicated that the root mean square error (RMSE) for IPL was 8mm, whereas for TLS it was 3mm. The lidar sensor has rapid scanning capabilities at a relatively cheap expense while maintaining an acceptable level of precision. However, it should not be regarded as a replacement for TLS, as the latter is an indispensable instrument for collecting data over wider distances. The causes for this are the sensor's precision, its ability to cover vertical space, and its restricted range, which is capped at a maximum of 5 meters. The sensor's specification is expected to undergo additional improvements and advancements, despite these limitations. A crucial tool for collecting data over extensive regions.

Supervised Machine Learning for Speaker Diarization by PNCC with LPCC Audio Coefficients

Hasan M. Kadhim, Alaa H. Ahmed, Alaa K. Hassan, Saad T. Alfalahi — Mon, 21 Oct 2024 01:23:23 +0300

Speaker Diarization is a speech digital signal processing technique that segregates one input observation of n multi-speaker signal into an individual speech of those n persons. Each segregated signal belongs to one of them plus a little bit of error which is speech that belongs to other speakers. The format of that speech is a dialog because they speak non-simultaneously (dialog). Using Speaker diarization algorithms, audio features are extracted from the standard TIMIT databases of speech. This extraction is the Training Stage of Machine Learning. The second Classification Stage can then decide how to divide these features into n groups. Linear Prediction Cepstral Coefficients (LPCC) and Power-Normalized Cepstral Coefficients (PNCC) are used independently to generate their features. In this paper, the researchers re-combinate these LPCC and PNCC features to form a new mixture of features. Modified Euclidian distance facilitates the job of measuring distances to identify who is the nearest label. Because PNCC is a non-inversible transformation, a small frame at the center of a large windowed frame has been regarded (because it has reasonable weight) to obtain original speech signals. The procedure was efficient for clustering a mixture of two speaker signals, female and male from the TIMIT standard audio library, i.e., successfully recovered each person's individual speech. The average Diarization Error Rate (DER) objective tests of the recovered speech were 1.8% for the females, 2.9% for the males, and 2.5% for the overall females and males. Compared with other standard researches, the improvements were 6.5% for the females, 10% for the males, and 8.8% for all females and males.
