         الملخّصتحاول هذه الدراسة، التي أحسب أنها الأولى من نوعها، أن تقدم مقارنة تحليلية للإرث الفكري للشيخين محمد عبد الوهاب (1703-1791م) في الجزيرة العربية وشاه ولي الله الدهلوي (1703-1761م) في شبه القارة الهندية في إطار واقعهما البيئي. وتخلص إلى أن لفظ "الوهابية الهندية"، الذي ابتدعه بعض المستشرقين لوصف حركة الإصلاح الإسلامي في الهند، والذي يوحي بأن رائدها الدِّهلوي كان مجرد نسخة مطابقة لمعاصره ابن عبد الوهاب، مصطلح غير دقيق، بل لعله خاطئ كليًّا. وذلك لأن دراسة الإرث الفكري لهذين العملاقين تبين بأنهما أسسا في عصر ما قبل الهجمة الإستعمارية على بلاد المسلمين مدرستين متباينتين من حيث التوجه والمحتوى.الكلمات المفتاحية: محمد عبد الوهاب، شاه ولي الله، الإرث الفكري، التجديد الإسلامي. Abstract          This is the first study to provide an analytical comparison of the intellectual legacy of two great scholars Muhammad ibn ‘Abd al-WahhÉb (1703-1791) in the Arabian Peninsula and Shah WalÊ Allah DehlawÊ (1703-1761) in the Indian sub-continent in the context of their respective environments. It concludes that the term “Indian Wahhabism”, which was coined by some Orientalists to describe the movement for Islamic reform in India, suggesting that Sheikh DehlawÊ was just a duplicate of contemporary Ibn ‘Abd al-WahhÉb, is not only inaccurate but completely incorrect. The study of the intellectual legacy of these two luminaries reveals that they both founded, prior to the pre-colonial attack on the Muslim world, two schools different in terms of orientation and content..Keywords: Muhammad ibn ‘Abd al-WahhÉb, ShÉh WalÊ Allah DehlawÊ, Intellectual Heritage, Islamic Revival.

<div> <div> <div> <p>Abstract </p> <p>The ceaseless connectivity imposed by the internet has made many vulnerable to offensive comments, be it their physical appearance, political beliefs, or religion. Some define hate speech as any kind of personal attack on one’s identity or beliefs. Of the many sites that grant the ability to spread such offensive speech, Twitter has arguably become the primary medium for individuals and groups to spread these hurtful comments. Such comments typically fail to be detected by Twitter’s anti-hate system and can linger online for hours before finally being taken down. Through sentiment analysis, this algorithm is able to distinguish hate speech effectively through the classification of sentiment. </p> </div> </div> </div>

Accident Severity

Smart city has come a long way since the development of emerging technology like Information and communications technology (ICT), Internet of Things (IoT), Machine Learning (ML), Block chain and Artificial Intelligence. The Intelligent Transportation System (ITS) is an important application in a rapidly growing smart city. Prediction of the automotive accident severity plays a very crucial role in the smart transportation system. The main motive behind this research is to determine the specific features which could affect vehicle accident severity. In this paper, some of the classification models, specifically Logistic Regression, Artificial Neural network, Decision Tree, K-Nearest Neighbors, and Random Forest have been implemented for predicting the accident severity. All the models have been verified, and the experimental results prove that these classification models have attained considerable accuracy. The paper also explained a secure communication architecture model for secure information exchange among all the components associated with the ITS. Finally paper implemented web base Message alert system which will be used for alert the users through smart IoT devices.

Recurrent Gbm

Anti-angiogenic therapy with bevacizumab is a widely used therapeutic option for recurrent glioblastoma (GBM). Nevertheless, the therapeutic response remains highly heterogeneous among GBM patients with discordant outcomes. Recent data have shown that radiomics, an advanced recent imaging analysis method, can help to predict both prognosis and therapy in a multitude of solid tumours. The objective of this study was to identify novel biomarkers, extracted from MRI and clinical data, which could predict overall survival (OS) and progression-free survival (PFS) in GBM patients treated with bevacizumab using machine-learning algorithms. In a cohort of 194 recurrent GBM patients (age range 18–80), radiomics data from pre-treatment T2 FLAIR and gadolinium-injected MRI images along with clinical features were analysed. Binary classification models for OS at 9, 12, and 15 months were evaluated. Our classification models successfully stratified the OS. The AUCs were equal to 0.78, 0.85, and 0.76 on the test sets (0.79, 0.82, and 0.87 on the training sets) for the 9-, 12-, and 15-month endpoints, respectively. Regressions yielded a C-index of 0.64 (0.74) for OS and 0.57 (0.69) for PFS. These results suggest that radiomics could assist in the elaboration of a predictive model for treatment selection in recurrent GBM patients.

Boosted Tree

This research presents Gradient Boosted Tree High Importance Path Snippets (gbt-HIPS), a novel, heuristic method for explaining gradient boosted tree (GBT) classification models by extracting a single classification rule (CR) from the ensemble of decision trees that make up the GBT model. This CR contains the most statistically important boundary values of the input space as antecedent terms. The CR represents a hyper-rectangle of the input space inside which the GBT model is, very reliably, classifying all instances with the same class label as the explanandum instance. In a benchmark test using nine data sets and five competing state-of-the-art methods, gbt-HIPS offered the best trade-off between coverage (0.16–0.75) and precision (0.85–0.98). Unlike competing methods, gbt-HIPS is also demonstrably guarded against under- and over-fitting. A further distinguishing feature of our method is that, unlike much prior work, our explanations also provide counterfactual detail in accordance with widely accepted recommendations for what makes a good explanation.
