In this paper, a Support Vector Regression (SVR) based controller for TIM speed control using Indirect Vector Control (IVC) is presented. The IVC method is more frequently used because it enables better speed control of the TIM with higher dynamic performance. Artificial Neural Network (ANN) controllers have been widely used for TIM speed control for several reasons such as their ability to successfully train without prior knowledge of the mathematical model, their learning ability, and their fast implementation speed. The SVR-based controller overcomes the drawbacks of the ANN-based controller, i.e. its low accuracy, overfitting, and poor generalization ability. The speed response under the proposed controller is faster in terms of rising and settling time. The dynamic speed response of the proposed controller is also superior to t...

This procedure holds significant in the field of Natural Language Processing (NLP) and find utility across a variety of NLP applications. Commonly, it constitutes the initial phase of natural language processing. Subsequent stages may encompass additional tasks such as chunking, parsing and more. Balochi stands as the predominant language in Balochistan,, ranking as the fourth most prevalent language in Pakistan. The field of natural language processing for Balochi is still in its nascent stages. In this research, we introduce an algorithm for Balochi part-of-speech tagging, leveraging machine learning techniques. The core of our approach relies on a Conditional Random Field model as the machine learning component. Careful consideration is given to selecting appropriate features for the CRF, taking into account the linguistic characteristics of Balochi. Balochi is currently considered a resource poor language, and thus, the available manually tagged data consists of only approximately 1500 sentences. The tagset used in this study created for research purpose, consisting of 16 different tags. The learning process incorporates tagged data. The algorithm demonstrates a high accuracy rate of 86.78% when applied to Balochi texts. The training corpus comprises 40000 words, while the test corpus contains 10000 words.

The main objective of this perspective paper is to summarize the problem space of representation of security patterns when designing security requirements. Many security patterns are proposed in the literature to help the developers who lack expertise in security to implement it. Application of security patterns has been hindered by the fact that they lack directions for their implementation in a specific scenario. This paper presents a technique for using mitigation use cases for representing solution provided by security patterns. Different challenges and issues were identified related to the application of security patterns in industry

One of the major problem to cope with, is its scalability. It means if the number of nodes increases then the protocol should not intensely affected regarding the performance. For the transmission of live multimedia streaming or one-to-many type multicast applications in open-MANETs (any number of interested nodes which are in the transmission range may join in the network) a scalable multicast routing protocol is still in need by the researchers. SLIM+ (Advanced-Simple Lightweight Intuitive Multicast) which has a tree based distribution structure is introduced as a protocol to perform in open-MANETs for these type of multicast applications. SLIM+ ensures an advertisement mechanism that is much needed feature in open-MANETs (Vehicular Ad-Hoc Networks/VANETS and Local area social Networks...
