Speech is a primary means of human communication and one of the most basic features of human conduct. Voice is an important part of its subsystems. A speech disorder is a condition that affects the ability of a person to speak normally, which occasionally results in voice impairment with psychological and emotional consequences. Early detection of voice problems is a crucial factor. Computer-based procedures are less costly and easier to administer for such purposes than traditional methods. This study highlights the (...) following issues: recent studies, methods of voice pathology detection, machine learning and deep learning (DL) methods used in data classification, main datasets utilized, and the role of Internet of things (IoT) systems employed in voice pathology diagnosis. Moreover, this study presents different applications, open challenges, and recommendations for future directions of IoT systems and artificial intelligence (AI) approaches in the voice pathology diagnosis. Finally, this study highlights some limitations of voice pathology datasets in comparison with the role of IoT in the healthcare sector, which shows the urgent need to provide efficient approaches and easy and ideal medical diagnostic procedures and treatments of disease identification for doctors and patients. This review covered voice pathology taxonomy, detection techniques, open challenges, limitations, and recommendations for future directions to provide a clear background for doctors and patients. Standard databases, including the Massachusetts Eye and Ear Infirmary, Saarbruecken Voice Database, and the Arabic Voice Pathology Database, were used in most articles reviewed in this article. The classes, features, and main purpose for voice pathology identification are also highlighted. This study focuses on the extraction of voice pathology features, especially speech analysis, extends feature vectors comprising static and dynamic features, and converts these extended feature vectors into solid vectors before passing them to the recognizer.

On modern philosophy, with reference to the ideology of Sir Muhammad Iqbal, 1877-1938.

Collected interviews of philosophers of 20th century, chiefly about the modern philosophy and its theories.

In his book Visions of Politics, Quentin Skinner argued that a scholar's primary concern is to situate texts and terms within their intellectual contexts in order to make sense of their authors' meaning. Skinner also stressed the history of the uses to which moral terms have been put, and their meanings for the agent performing them. While admitting the difficulties of such method with early Muslim writings, Hikmet Yaman is to be congratulated on his thorough analysis of ḥikma, commonly translated (...) as 'wisdom,' one of the most important yet under-researched Islamic concepts. In his Prophetic Niche in the Virtuous City: The Concept of Ḥikma in Early Islamic Thought, Yaman follows Skinner's call and treats the .. (shrink)

Sufism has two main dimensions: vertical (God's pleasure) and horizontal (harmony with nature, society and local wisdom). In reality, many Sufis are considered less concerned about the balancing between vertical and horizontal dimensions. The research explores the concepts and practices of hybrid Sufism undertaken by Kyais (religious leaders) and their followers in improving quality of life. Ethnography was used for exploring the mindset and activities of Kyai and his followers. This study involved four Kyais in Java and Kalimantan, Indonesia. Research (...) data were obtained through participant observations, in-depth interviews and documentation. The data were analysed by Spadley's ethnographic steps as follows: (1) domain analysis, (2) taxonomy analysis, (3) componential analysis and (4) cultural-thematic analysis. The results showed that hybrid Sufism could improve quality of life. Hybrid Sufism can better appreciate and interpret local wisdom with an attitude of preserving nature and a positive understanding of worldly wealth, increasing the hard work ethos to achieve material-spiritual qualities. CONTRIBUTION: This article shows that hybrid Sufism encourages the life of Sufis in harmony between vertical and horizontal aspects. This understanding and lifestyle give rise to respect for others, being friendly to the environment and interpreting life and local wisdom. (shrink)

Smart lighting systems utilize advanced data, control, and communication technologies and allow users to control lights in new ways. However, achieving user comfort, which should be the focus of smart lighting research, is challenging. One cause is the passive infrared sensor that inaccurately detects human presence to control artificial lighting. We propose a novel classification-integrated moving average model method to solve the problem. The moving average increases the Pearson correlation coefficient of motion sensor features to human presence. The classification model (...) is for a smart lighting intelligent control based on these features. Several classification models are proposed and compared, namely, k-nearest neighbor, support vector machine, decision tree, näive Bayes, and ensemble voting. We build an Internet of things system to collect movement data. It consists of a PIR sensor, a NodeMCU microcontroller, a Raspberry Pi-based platform, a relay, and LED lighting. With a sampling rate of 10 seconds and a collection period of 7 days, the system achieved 56852 data records. In the PC test, movement data from the PIR sensor has a correlation coefficient of 0.36 to attendance, while the MA correlation to attendance can reach 0.56. In an exhaustive search of an optimum classification model, KNN has the best and the most robust performance, with an accuracy of 99.8%. It is more accurate than direct light control decisions based on motion sensors, which are 67.6%. Our proposed method can increase the correlation value of movement features on attendance. At the same time, an accurate and robust KNN classification model is applicable for human presence-based smart lighting control. (shrink)

Of the many illustrious figures of the Buyid period none is perhaps as intriguing, or as enigmatic, as Abū Hayyān al-Tawhīdī. We know all too little of his biography. He was probably born between 310/922 and 932 but whether in Baghdad, Shiraz, or Nishapur remains uncertain. From his works we know that he studied in Baghdad under such renowned scholars as the jurist and qādī Abū Hāmid al-Marwazī. He tells us that he was in Mecca in 353/964 and, in 366/976, (...) at the court of the vizier Abū al-Fath Ibn al-'Amīd in Rayy—an unhappy experience that informs his scathing portrayal of that vizier, as of the Sāhib Ibn 'Abbād, in his Akhlāq al-Wazīrayn, one of his literary masterpieces. More significantly for the book under... (shrink)

In this study, the words that Abū al-Ṭayyib al-Lughawī did not consider as aḍdādwhile his predecessors accepted the same words as aḍdād(contronym), are examined. These words are examined with the purpose of determining his approach towards contronmy words (aḍdād). There is disagreement about the definition and the number of aḍdāds, which can shortly be defined as the word which has two opposite meanings. In this study, brief information about the definition and limitation of aḍdādand the reasons that produce aḍdādare given, (...) and then the words that Abū al-Ṭayyib does not accept as aḍdād are analysed under the four titles – based on the classification made by himself. The author does not accept the words which have the same ism al-fāʿil(active participle) and ism al-mafʿūl(passive participle) format because of the verb’s being ecwefor the middle letter’s being combined with the final letter of the verb as aḍdād. Besides, he does not accept the words that have two opposite meanings due to their figurative meaning as aḍdād. He also states that he does not take the words included inaḍdādcategory just because their meanings are reversed by Arabs as aḍdād. With this attitude, the author has rendered the concept more comprehensible by showing what is not aḍdād. In this study, Abū al-Tayyib’s work named Kitāb al-aḍdādis taken as the primary text, and the pieces of poetry and prose shown as examples by the author are stated with their primary sources.SummaryThere are many scholars who worked on aḍdād, which is a terminological expression for the words that have two opposite meanings. Abū al-Ṭayyib al-Lughawī is one of the scholars to write a work about this subject. The author had the opportunity to examine most of the studies about aḍdādand making a comparison between these studies, he wrote Kitāb al-Aḍdād fı̄ kalām al-ʿArab. The work was composed by arranging the words, which had been accepted as aḍdādby the former scholars, in an alphabetical order according to their initial letters alone. The author completed his work by using expressions showing his objection or confirmation about the words’ being aḍdādor not while mentioning the words. Abū al-Ṭayyib added an addendum to the end of the work and in this section, he noted some words which the former scholars had accepted as aḍdādbut he did not. Although he explained the reason of adding this addendum as not to be thought of unaware of these words, he aimed to correct a mistake made by the previous linguists by identifying it thanks to the mentioned addendum.The words الجَوْن(used both with the meaning of black and white), النوء(to arise and to set), الصَّرِيم(night and day), جَلَل(big and small) and السُّدْفَة(dark and light) can be given as examples for the concept of aḍdād, which is terminologically used for the words having two opposite meanings. The words such as البَيْع(to sell and to buy), بَصِير(sighted and blind), ثَلَّ(to repair and to bring down), الأخْضَر(green and black), الخَلّ(well- fed calf/camel and undernourished calf/camel, which have two opposite meanings at the same time, are among the words that Abū al-Ṭayyib presents as aḍdādin his work. Although there are various definitions of aḍdād, the clearest and most comprehensive one belongs to Abū al-Ṭayyib. He makes the following definition which distinguishes aḍdādfrom common wording: “Aḍdādis the plural form of didd(antonym). Antonym means the opposite of something, such as black and white, generosity and meanness, courage and cowardice. Everything that is opposite of something is not necessarily the antonym of it. For example, although strength and ignorance are two opposite words, they cannot be taken as antonyms. Because, the antonym of strength is weakness and the antonym of ignorance is knowledge. This difference arises from the fact that the term opposite is more comprehensive than the term antonym. Although all aḍdādwords are opposites, not all the opposite words are antonyms (aḍdād).” The biggest controversy about aḍdādis about the number of the words that are accepted as aḍdād. While some scholars represent the numbers of aḍdādwords in Arabic language as four hundred, they are not more than twenty for some other scholars. In spite of the controversy about the numbers of aḍdādwords in the language, the existence of aḍdādin Arabic language is an accepted situation.There are some reasons leading to aḍdādin Arabic language, one of which is dialect difference. The word السُدْفَةwhich is used for the meaning of “dark” by Temı̄m clan means “light” in Ḳays tribe. Some changes in language are also stated among the reasons causing aḍdād. It is stated that the original meaning of the word الصَّرِيمwas “interrupted,” but then it was used with the meaning of both night and day for the reason that night is interrupted by day and day is interrupted by night. Another reason is purported as being psychological and social factors. Using the term الكَرِيم“generous” to make fun of a mean person is an example for this situation. One of the reasons causing aḍdādis the morphological structures of the words. As it is the case with the word خائِفٌ“frightened/frightening,” the use of ism al-fāʿiland ism al-mafʿūlmodes in the same form has caused to using the same word with two opposite meanings. There are also some scholars who accept the words that gain two opposite meaning to each other because of rhetorical factors like metaphor. Using the word إِرَةٌboth with the meaning of fireand metaphorically the pit where fire is lightedis an example for this sort. The scholars’ acceptance or rejection of the reasons leading to aḍdādhas resulted in their expanding or narrowing the numbers ofaḍdādwords in the language. In this context, the numbers of aḍdādwords are more for a scholar who accepts most of the reasons mentioned. Abū al-Ṭayyib is among the scholars to cast a wide scope for aḍdādwords. Since the author accepts the aḍdādwords arising from dialect and metre difference, the words that he takes as aḍdādare quite many. In Kitāb al-aḍdād, he states that there are total of 320 aḍdādwords and at the same time he collects the words that he does not accept as aḍdād but which were accepted so by the former scholars under four headings. In the first group, there are the words thought as aḍdādbecause of being an ecwefverb. For the author, the reason these words are supposed to be aḍdādis that ism al-fāʿil(active participle) and ism al-mafʿūl(passive participle) modes of these words turn into the same structure as a result of ʿilālrules. The fact thatالمُجْتَابmeans both “the one who wears” and “the thing that is worn”; المُبْتَاعis used as ism al-fāʿilwith the meaning of “the one who buys stuff” and as ism al-mafʿūl with the meaning of “the stuff sold” is an example for this situation. In the second group, there are the words which are taken as aḍdādbecause of merging (idghām) middle letter of the word to its final letter. It is seen that ism al-fāʿiland ism al-mafʿūl forms of these words are the same due to various reasons. The fact that مُكْتَنٌّis used both for disguisedand the place to disguise; مُحْتَشٌّis used for “the one who gathers grass” and “the grass gathered” is of this sort. In the third group, there are words which are assumed to be aḍdādas they are named after their reasons. There is mostly metaphorical meaning in the words that are placed in this group. One of the words that Abū al-Ṭayyib presents as an example to this group is العَقِيقَة. ʿAqı̄qameans the hair on the head of the baby when it is born. An animal is sacrificed when this hair is shaved. In time, the animal sacrificed has begun to be called as ʿaqı̄qa, as well; and so, ʿaqı̄qais used both for the hair and the sacrifice. Abū al-Ṭayyib argues that such words are absolutely not aḍdād. In the fourth group, there are expressions that result from fāʿil’s replacing mafʿūland mafʿūl’s replacing fāʿilor the words that appear in similar ways. For instance, using the expression “the lizard climbed up the tree” not with the common usage اِنْتَصَبَالْحِرْبَاءُفِيالْعُودِbut by changing the places of fāʿiland mafʿūlاِنْتَصَبَالْعُودُفِيالْحِرْبَاءِis an example for this group. Abū al-Ṭayyib objects to the acceptance of the words used in this way as aḍdād, and argues that aforesaid usages do not comply with the definition of aḍdād. (shrink)
