What is pwa?5 answersA Progressive Web Application (PWA) is a piece of software that functions as an online application without the need for installation or publication in any app store. It can be accessed through a website-like interface and added to the user's home screen for easy access. PWAs work on any platform, including desktops and smartphones, and do not occupy storage space like traditional apps. They are created using frameworks like ReactJS for the user interface and can utilize APIs like MongoDB for server functionality. PWAs have various applications, such as optimizing parametric models in nuclear and particle physics experiments, managing college activities for teachers and students, and providing a cost-effective solution for data collection in small and medium-sized businesses. They can also assist users in managing their clothing, combining outfits, and scheduling based on weather and temperature.
What is ppm?4 answersPulse-position modulation (PPM) is a form of signal modulation that encodes message bits by transmitting a single pulse in one of several possible time shifts. It is primarily used in optical communications systems and has applications in fiber-optic communications and deep-space communications. PPM is a time-domain version of frequency-shift keying and is used to encode variable pulses to specific positions within a period. PPM is also used in R/C systems and is known for its resistance to multipath interference. In the field of erasure codes, an optimization algorithm called Partitioned and Parallel Matrix (PPM) has been developed to accelerate the encoding/decoding processes of certain erasure codes, resulting in faster performance. Additionally, PPM has been used in the field of protein structure assessment, where a chemical shift predictor called PPM has been developed to predict protein backbone and side-chain NMR chemical shifts based on physical-chemical contributions.
What is a PBFT?5 answersA Practical Byzantine Fault Tolerance (PBFT) is a consensus algorithm used in blockchain networks to ensure agreement among participating nodes. PBFT is a voting-based algorithm with a time complexity of O(n^2), which limits its scalability. To address this limitation, a hierarchical grouping technique is proposed, where nodes in a PBFT-based blockchain network are grouped and managed dynamically. Another approach called P-PBFT combines PBFT with grouping and credit voting to improve latency, system overhead, and scalability in pharmaceutical traceability systems. R-PBFT introduces a reputation mechanism to enhance the PBFT consensus process, resulting in reduced consensus delay, increased transaction frequency, and improved throughput. The PBFT algorithm can also be formally developed using horizontal refinement in Event-B, allowing for the verification of safety and liveness properties. RP-PBFT introduces a reward and punishment mechanism to improve efficiency, scalability, and communication complexity in PBFT-based consensus.
What is PTPTN?3 answersPTPTN stands for Perbadanan Tabung Pendidikan Tinggi Nasional, which is a government organization in Malaysia that provides education loans to Malaysian students. It is also known as the National Higher Education Fund Corporation. PTPTN has been in the news for low repayment rates from its borrowers. To address this issue, PTPTN has collaborated with immigration bodies and credit reference systems to minimize inactive repayment by borrowers. The organization has a portal that is used by students, and their satisfaction with the portal's performance is an important factor. PTPTN considers factors such as media influence, borrowers' attitude, affordability, and incentives towards loan repayment when analyzing the factors influencing graduates' repayment of education loans. Additionally, PTPTN has explored the use of Islamic mediation and the Sulh approach to reconcile conflicts and disputes in loan repayment.
What is PyFMI?5 answersPyFMI is a Python package that supports loading and execution of models compliant with the Functional Mock-up Interface (FMI) standard. It provides a standardized and unified model execution interface for dynamic models, known as Functional Mock-up Units (FMUs). PyFMI allows for the simulation of coupled FMUs and includes connections to both Assimulo and SciPy for single FMU simulation and parameter estimation respectively. The package aims to make models compliant with FMI accessible in Python, which is an open and accessible scripting language. PyFMI has been demonstrated to be viable for solving industrial grade simulation problems with FMUs.
What is the difference of PFA and PFB?5 answersPFA and PFB are both types of fluoropolymers used in various applications. PFA, or perfluoroalkoxy, is a fluoropolymer that is commonly used for its resistance to heat, corrosion, and the sun. It is often used in the production of color masterbatch, motor protection bags, and tube sleeve extension devices. On the other hand, there is no specific mention of PFB in the provided abstracts. Therefore, it can be inferred that PFB is not discussed in these papers and may not be a commonly used term in the context of these abstracts.
