since the early 1990s, when people first started to talk about WDM and other optical-networking concepts in the quest for virtually unlimited bandwidth capacity. As advancements took place in R&D laboratories around the world, device technologies emerged to make the building of the core components of these optical telecommunications networks a reality. The worldwide demand for these components ...

The cost eeective ABR service is suitable for transmitting bursty compressed video over ATM network. Here, we propose a Fast Buuer Fillup (FBF) scheme to run VoD over ATM network with ABR service. We develop models to determine buuer size at the client and the server for our scheme. We also develop relationships between the startup delay, the ABR service parameters, and the network congestion s...

Abstract We currently observe the rapid emergence of startups that use Artificial Intelligence (AI) as part their business model. While recent research suggests AI employ novel or different models, one could argue technology has been used in models for a long time already—questioning novelty those models. Therefore, this study investigates how startup potentially differ from common IT-related F...

Seeing the potential for healthtech startups that continue to emerge in Indonesia, of course companies must create innovations be able compete with existing and future competitors, one which is by doing a revamp or process change appearance user journey. As was done startup companies, namely PT. Global Urban Essentials its products, Teman Bumil application. This research conducted redesign disp...

Practical applications of microbial fuel cells (MFCs) for wastewater treatment will require operation of these systems over a wide range of wastewater temperatures. MFCs at room or higher temperatures (20-35°C) are relatively well studied compared those at lower temperatures. MFC performance was examined here over a temperature range of 4-30°C in terms of startup time needed for reproducible po...

The fully thermally coupled distillation column offers an alternative to conventional distillation towers, with the possibility of savings in both energy and capital costs. This innovative and promising alternative provides the opportunity to separate a multicomponent mixture into fractions with high purities merely in one column. A lack of knowledge still exists when dealing with the startup o...

Social media has been an incredible platform for startups to develop meaningful connections with stakeholders and customers. We investigate ways in which entrepreneurs use social media to drive both the level of engagement for their startup and the subsequent level of venture financing. Our empirical analysis demonstrates how differences in entrepreneurs’ tweets—i.e., differences in the level i...

A protocol named Threshold Bipolar (TB) is proposed as a fetching strategy at the startup stage of p2p live streaming systems. In this protocol, chunks are fetched consecutively from buffer head at the beginning. After the buffer is filled into a threshold, chunks at the buffer tail will be fetched first while keeping the contiguously filled part in the buffer above the threshold even when the ...

A modified oxygen uptake rate (OUR) test for characterizing the performance of integrated fixed-film activated sludge (IFAS) processes was developed while monitoring the startup of a full-scale demonstration facility. Data on total biofilm solids, in-basin nitrification rates, and batch nitrification rates were compared to the OUR test. The data was used to investigate dynamic changes in the ph...
