A Novel Approach to Railway Track Faults Detection Using Acoustic Analysis

Sensors (2021)

Rahman Shafique Hafeez Ur Rehman Siddiqui Furqan Rustam Saleem Ullah Muhammad Abubakar Siddique

Regular inspection of railway track health is crucial for maintaining safe and reliable train operations. Factors, such as cracks, ballast issues, rail discontinuity, loose nuts and bolts, burnt wheels, superelevation, and misalignment developed on the rails due to non-maintenance, pre-emptive investigations and delayed detection, pose a grave danger and threats to the safe operation of rail transport. The traditional procedure of manually inspecting the rail track using a railway cart is both inefficient and prone to human error and biases. In a country like Pakistan where train accidents have taken many lives, it is not unusual to automate such approaches to avoid such accidents and save countless lives. This study aims at enhancing the traditional railway cart system to address these issues by introducing an automatic railway track fault detection system using acoustic analysis. In this regard, this study makes two important contributions: data collection on Pakistan railway tracks using acoustic signals and the application of various classification techniques to the collected data. Initially, three types of tracks are considered, including normal track, wheel burnt and superelevation, due to their common occurrence. Several well-known machine learning algorithms are applied such as support vector machines, logistic regression, random forest and decision tree classifier, in addition to deep learning models like multilayer perceptron and convolutional neural networks. Results suggest that acoustic data can help determine the track faults successfully. Results indicate that the best results are obtained by RF and DT with an accuracy of 97%.

فقہ اسلامی میں بیع سلم کاتصور اورمروجہ اسلامی مالیاتی نظام میں بیع سلم کے استعمال سے متعلق اشکالات:ایک فقہی مطالعہ

FIKR-O NAZAR فکر ونظر (2021)

Muhammad Abubakar Siddique

The sharī‘ah invalidates the sale of non-existing items, but salam sale was exceptionally permitted to avoid interest-based financing in commercial as well as non-commercial transactions. Salam sale is an Islamic forward sale contract, which authorizes selling something that is not present during the time of the contract. Salam is a sale agreement whereby the seller receives full price in advance and goods are delivered at a future date. Moreover, it is free from uncertainties and exploitation that is usually involved in interest-based financing. Besides the agriculture sector, currently, this instrument is also being used in the manufacturing sector where the manufacturer would need financing to produce products and/or to buy raw materials. Modern financial innovations introduced different uses of salam sale such as parallel salam, currency salam, salam sukūk etc. There are different fiqh issues related to such uses of salam in modern financial sectors. This article elaborates on the economic importance and conditions that are necessary and sufficient to makethe contract valid from the perspective of the sharī‘ahand also appraises some of the key issues related to modern practices regarding salam.

Scientific papers citation analysis using textual features and SMOTE resampling techniques

Pattern Recognition Letters (2021)

Muhammad Umer Saima Sadiq Malik Muhammad Saad Missen Zahid Hameed Zahid Aslam

Ascertaining the impact of research is significant for the research community and academia of all disciplines. The only prevalent measure associated with the quantification of research quality is the citation-count. Although a number of citations play a significant role in academic research, sometimes citations can be biased or made to discuss only the weaknesses and shortcomings of the research. By considering the sentiment of citations and recognizing patterns in text can aid in understanding the opinion of the peer research community and will also help in quantifying the quality of research articles. Efficient feature representation combined with machine learning classifiers has yielded significant improvement in text classification. However, the effectiveness of such combinations has not been analyzed for citation sentiment analysis. This study aims to investigate pattern recognition using machine learning models in combination with frequency-based and prediction-based feature representation techniques with and without using Synthetic Minority Oversampling Technique (SMOTE) on publicly available citation sentiment dataset. Sentiment of citation instances are classified into positive, negative or neutral. Results indicate that the Extra tree classifier in combination with Term Frequency-Inverse Document Frequency achieved 98.26% accuracy on the SMOTE-balanced dataset.

Bleeding detection in wireless capsule endoscopy images based on binary feature vector

Shangbo Zhou Xinying Song Muhammad Abubakar Siddique Jie Xu Ping Zhou

Wireless Capsule Endoscopy (WCE) is a non-invasive way which is getting its popularity in many hospitals for gastrointestinal examination. However, it produces too many images that need physicians to check manually. This is a huge burden for physicians. To solve this problem, an automatic method based on Support Vector Machine is proposed in this paper. A binary feature vector is used to overcome the drawbacks of conventional color histogram, which compares similarity between histograms rather than checks out the existence of a specified pattern. Considering the property of WCE images, a clipped illumination invariant color space is introduced. Experiments demonstrate that the binary feature vector is more effective than histograms in detecting bleeding patterns of WCE images.

Reconciling the irreconcilable (talfeeq): The case of currency salam

International Journal of Finance & Economics (2021)

Muhammad Siddique Muhammad Abubakar Siddique

Abstract Currency salam is a financial product in the basket of Islamic finance that facilitates dealings in discounting of bills. Moreover, it allows provision for speculative future currency trading. This article shows that currency salam is prohibited in the light of Islamic rules of riba . Researchers have held three positions about modern currencies. The paper shows that the permissibility of currency salam is derived by combining together these three irreconcilable views about modern currencies. In other words, currency salam is the outcome of a fallacious methodology known as talfeeq which is merely a device of creating legal artifices ( hiyal ) for satisfying one's desires. It is argued that the permission of currency salam must be rejected because it is riba and it opens up the flood‐gate for financial speculations in the name of Islam. The paper also attempts to draw attention of the regulatory authorities to tackle this issue seriously as it will adversely affect the trust on Islamic banking regarding its Shariah compliance.

اسلامی بینکاری میں شرکت کا تصور: مشارکہ اور اس سے متعلّق چندفقہی اشکالات کا تجزیہ (The Concept of Shirkah in Islamic Banking: Musharkah and Analysis of Some Relative Fiqhi Issues)

SSRN Electronic Journal (2017)

Muhammad Abubakar Siddique

Urdu Abstract:اسلام کسب معاش کے لیے تجارت کو دوسرے تمام ذرائع پر فوقیت دیتا ہے اور ایسی تجارت کی حوصلہ افزائی کرتا ہے جو پاکیزہ ہو اور اس کی بنا اسلامی اصولوں پر استوار ہو۔ اسلامی نظام معیشت ہر دوبائع اور مشتری کے حقوق کی حفاظتی ضمانت فراہم کرتا ہے اور تجارت جیسی خالص مادی سرگرمی میں بھی ایسے اخلاقی اصولوں کی پیروی کرنے کا حکم دیتا ہے جو فریقین کے درمیان اخوت و محبت کے جذبات کو پروان چڑھانے کا باعث بنتے ہیں۔ اسلام نے تجارت کے لیے جو طرق تمویل (Modes of Financing) متعین کیے ہیں، ان کی فہرست طویل ہے۔ اس مقالے میں ان طرق تمویل میں سے صرف مشارکہ اور اسکی اقسام سے متعلق بحث کی جائے گی، جسے شرکت کے نام سے بھی موسوم کیا جاتا ہے۔ اس مقالے میں اسلامی بنکوں کے ہاں شرکت یا مشارکہ کے نام سے کیے جانے والے باہمی لین دین سے متعلق مروجہ طریق کار کا فقہی اصولوں کی روشنی میں جائزہ لیا جائے گا۔ اس مقالے کا بنیادی مقصد مشارکہ سے متعلق پائی جانے والی غلط فہمیوں کا ازالہ کرنا ہے ، جیسے اسلامی بینک ، سودی بینک کی طرح نفع کا تعین کرتے ہیں۔ اسلامی بینک میں لین دین کا سارا عمل سودی بینک کی طرح ہی ہوتا ہے وغیرہ وغیرہ۔اس کے ساتھ ساتھ مشارکہ کے حوالے سے چند فقہی اشکالات کا محاکمہ بھی پیش کیا جائے گا، تاکہ شرکت کے اسلامی تصور اور اسلامی بینکوں میں اس کی صحیح عملی تعبیر واضح ہوجائے ۔ English Abstract: Economic objective of Profit maximization, by nature, inflame person’s lust of wealth accumulation irrespective of permissible or prohibited means of money making. As a result, a person prefers to make easy money without bearing any troublesome. Therefore, he deals in interest based lending and makes guaranteed profit along with his principle amount. Islam prohibited such type of business considering it riba (interest), but provides an alternate of it in form of sale and shirkah (partnership). According to shirkah, person can make profit stipulated that he will bear risk of loss on his principle and share loss with his partner and that’s it. There is no other way to earn profit other than sale and shirkah. In modern Islamic Banking shirkah is being practiced in form of Musharkah. There are many issues regarding conceptual awareness of modern Musharkah, its applications, and newly developed product Diminishing Musharkah. After explaining the shirkah, Diminishing Musharkah is discussed in detail. Finally, this study analyzes and highlights the relative fiqhi issue.

OBJECTIVE: To determine the quantitative comparison of handgrip strength between cardiac patients and age matched healthy controls using a handheld dynamometer.METHODS: This quantitative comparison cross-sectional study was conducted at University of Lahore teaching hospital, Lahore from 17th, October 2017 to 5th February 2018. Twenty cardiac and twenty age matched healthy participants were selected using consecutive (non-probability) sampling technique. After approval from ethical committee, data was collected using questionnaire. Measurements were taken of grip strength of both hands by using Jammer Dynamometer. This method was repeated three times in order to obtain mean value of both hands.RESULTS: In this study 40 subjects were studied with mean age of the participants as 62.08±7.63years. Among them 23(57.5%) were male and 17(42.5%) were female. Mean age of males were 65±7.37years whereas mean age of females were 64.11±7.75years. Out of twenty cardiac patients, 12(60%) male and 5 (25%) female were suffering from myocardial infarction, 3(15%) female had Angina. Twenty participants of age-matched healthy individual group included 11 (55%) males and 9 (45%) females. In quantitative comparison of the dominant handgrip strength of cardiac patients (54.28 ± 27.75) and age matched healthy control (74.78±30.33) there was noteworthy difference in mean values of both groups with significant p-value of 0.032 whereas in the strength of non-dominant hand grip in cardiac patients (54.11±26.46) and age matched healthy control (71.03±29.25), no significant difference was recorded.CONCLUSION: Grip strength of dominant hand is less in cardiac patients as compared to healthy normal individual with significant relationship whereas there is no significant difference among non-dominant hand strength in both groups.KEY WORDS: Grip strength (Non-MeSH); Dominant & Non-dominant (Non-MeSH); Cardiac patient (Non-MeSH); Myocardial Infarction (MeSH); Muscle Strength Dynamometer (MeSH); Muscle Strength (MeSH).

Review of: "Does Intellectual Capital Efficiency Translate in the Post-pandemic Era for Islamic Banks in Indonesia?"

Muhammad Abubakar Siddique

Comments …………………………………In econometrics, banking, and economics research, conducting regression analysis with a small sample size can lead to several challenges and limitations.Here are some comments on the scenario you presented:With only 20 observations, the reliability and robustness of the results may be questionable.Small sample sizes can lead to high variability in estimates and low statistical power, making it difficult to draw meaningful conclusions.The fact that two out of three independent variables became highly insignificant suggests potential issues with statistical power or model specification.In a panel data context, where you typically have both cross-sectional and time-series dimensions, it's essential to ensure that the chosen variables are appropriate and the model adequately captures the underlying relationships.Panel data analysis allows for controlling for both individual-specific and time-specific effects, which can improve the efficiency and accuracy of estimates.However, in this case, the small sample size may limit the effectiveness of panel data techniques in addressing omitted variable bias or other model specification issues.It's crucial to carefully consider the specification of the regression model.Omitted variables, multicollinearity, or functional form misspecification can lead to biased and inconsistent parameter estimates.The insignificance of certain variables may indicate that they are not relevant in explaining the variation in the dependent variable, or it could be a symptom of model misspecification.Researchers should perform robustness checks to assess the sensitivity of their results to different model specifications, sample selections, or estimation techniques.Given the small sample size, conducting sensitivity analysis becomes even more critical to ensure the reliability of the findings.With only 20 observations, any conclusions drawn from the analysis should be made cautiously.The results may not be generalizable to a broader population, and the estimated coefficients may lack precision.
