Latency is rapidly becoming critical in cloud computing. Latest services and applications in various vertical markets requir low latency. Today every type of business networking channels is running with blazing fast speed which requires ultra-low latency within minimum time scale. The industries which are achieving the lowest latency are surviving while other slow competitors fall behind. Users are demanding real-life applications with low latency which helps them to obtain their desire services within a very limited time in their range.
Networking communication relies on critical tasks such as Storage, communication, control management, and configuration, etc. to accommodate the effective communication. Cloud system with its prerequisites is developing rapidly. Cloud is a leading enabler for various communications tasks. In a congested network, the cloud is creating unbearable and unstable high latency for computerized gadgets which demand high bandwidth. This is an alarming situation for the performance of smart applications and mobile devices in a network. The flexibility of providing applications anywhere in dense network is the beauty of cloud, but this flexibility comes at the price of unstable, unpredictable high latencies which are horrific in this ultra-fast time-period.
Fog brings distributed resources near to different users to support fast streaming with reducing latency. Currently, mobile devices are gaining popularity due to their mobility.Technology enhancement from cloud to fog is a computation of distributing resources at the edge where fog bring it near to different mobile users to support fast streaming with reducinglatency. Fog networks are not very dense with distantly located servers, to provide services at the edge very speedily with low latency. Fog with emerging technology is best to keep a table latency for mobile communication. Currently, heavy data is delivering and retrieving from various geographically scattered users. So, theconceptual framework of fog to minimize the latency of mobile devices is proposed. This framework of fog is willing to sponsor mobile devices with their smart applications at the edge with low latency. So, it can provide data in minimal time to analyze and respond . to validate the performance of fog conceptual framework, algorithms are also presented. To check the performance of fog framework iFogSim (simulator) is also used. Fog is willing to keep the minimum stable by cut down the traffic burden for mobile users by providing services and resources near the user.
گزشتہ ایک برس کے دوران میں کووڈ کی وجہ سے آن لائن لیکچر دیتے ہوئے وہ کئی تجربات سے گزرا۔ پہلے پہل وہ اپنے دھیان میں لیکچر دیتا رہا۔ کچھ دنوں بعد اسے کیمرہ آف ہونے کے باوجود سٹوڈنٹس کی موجودگی اور عدم موجودگی کا اندازہ ہونے لگا۔ کبھی کبھی وہ کسی طالب علم کی موجودگی کی تصدیق کے لیے سوال بھی پوچھ لیتا تھا اور اس کا اندازہ درست نکلتا تھا۔ آہستہ آہستہ اسے مکمل ادراک ہونے لگا کہ کیمرہ آف ہونے کے باوجود کون سٹوڈنٹ موجود ہے اور کون لنک جوائن کرنے کے بعد سو گیا ہے ۔ ذہنی رابط برقی رابطے سے زیادہ موثر محسوس ہونے لگا۔ وہ کیمرہ آف ہونے کے باوجود دیکھنے پر قادر ہو گیا۔ کسی سٹوڈنٹ کا تصور کرتے ہی اس چہرے پر ہویدا اداسی ، بیزاری ، انہماک، دلچسپی اور نیم دلی سمیت دیگر کیفیات کا انکشاف ہونے لگتا تھا۔ وہ صرف غور سے آئی ڈی کی طرف دیکھتا اور سٹوڈنٹ کی ذہنی کیفیت ظاہر ہو جاتی۔ وہ مخاطب ہوئے بغیر کسی سٹوڈنٹ کی کیفیت پر رائے دیتا اور پھر متعلقہ سٹوڈنٹ کی حیرت کو انجوائے کرتا تھا۔ وہ دوران تدریس بہت سے تجربات سے گزرا ۔ اس کے دل میں ایک خیال زور پکڑنے لگا ۔ اس نے خیال کو جھٹکنے کی کوشش کی مگر ناکام رہا۔ اسی خیال کے زیرِ اثر ایک دن اس نے تمام سٹوڈنٹس کو کیمرے آن کرنے کا کہا ۔ سٹوڈنٹس اپنے اپنے کیمرے آن کر بیٹھ گئے ۔ وہ سب کو دیکھ سکتا تھا مگر اسی لمحے اسے شدید دھچکا لگا ۔ وہ کسی بھی سٹوڈنٹ کی کیفیت کو پڑھنے سے قاصر تھا ۔
Writing this article wants to describe, related to Yemeni legal regulations, namely the marriage of Muslim women in Yemen. Discussing the annulment of marriages for men who adhere to Islam or Muslims who do not marry Muslim women and women of the book in Yemen. As for the women of the People of the Book who can be married to Muslim men in Yemen, it is necessary to elaborate on the permissibility of marrying women who are not Muslim. Yemen itself fully takes the source of law in the text of the Koran where marriage regulations in Yemen between Muslim men and women of the book are permissible and regulated in Yemen's legal laws. On the other hand, interfaith marriages in other regions related to women of the book cannot be found, in Indonesia, for example, interfaith marriages only describe marriages between Muslims and those who are not Muslim or are not Muslim, there is absolutely no mention of women of the book. For this reason, this article wants to elaborate on the explanation regarding women of the People of the Book, amidst the debate whether or not it is permissible to marry women of the People of the Book, Yemen still adheres to the Al-Quran text which allows Muslim men to marry women of the People of the Book until now.
Every successful software product is required to be maintained at some later stage of its life cycle. This maintenance is constrained in different ways by its cost, lead-time, and quality. These constraints are not always straightforward enough to be precisely quantified and understood. If a company can predict the maintenance in advance it can plan its business accordingly. This can be attributed to software engineer’s ability to model the predicted maintenance effort required early in the development cycle. The customers now have keen interest in software quality requirements (i.e. quality attributes (QAs)), like maintainability, reliability, performance, and flexibility too. Therefore, the maintenance may be required from the product’s functionality or its quality point of view. Software architecture is an excellent vehicle to showcase the changes, especially related to QAs that take place over the time. The QAs are interlinked with each other that make the maintenance effort estimation more complex. Unless, we have effective maintenance profiles maintained from very early in the development cycle, it is quite difficult to achieve quality according to customer satisfaction. In this thesis, efforts have been made to identify mechanisms which ensure early maintenance prediction. Software architecture, in our opinion, is one such artifact which can effectively be used to address the above mentioned problems. Software architecture has assumed greater significance over the past two decades as an artifact which not only plays vital role in development of quality software but also in its maintenance and up gradation. In this thesis a methodology for prediction of software system’s maintenance based upon their software architecture design has been defined. As a secondary step the thesis also presents a complete methodology for ripple effect analysis based on quality attribute in order to cover the maintenance of software quality in addition to its functionality. The proposed method enables us to predict the overall maintenance effort quite early in the software development life cycle and provides an insight whether the components will remain consistent after the change or it will be come fluent and inconsistent. The proposed method can also help in better understandability of the software and consequently more reliable early planning.
