The startup time of open source desktop applications and environments does not compare well with other systems, especially closed-source systems. We perform a detailed analysis of the startup of the GNOME desktop environment using a mixture of available open-source tools and ad-hoc measuring techniques, identifying bottlenecks and examining strategies to improve performance. Our results show th...

SMB represents one of the widely established periodic adsorption processes and its periodic and nonlinear dynamics presents a significant challenge to the formulation and solution of the optimal startup issue. A multistage startup concept allowing to adjust operating conditions stage-wise is proposed. The startup problem is then formulated aiming at driving the system towards the reference cycl...

Scholars have long sought to understand the advantages different types of firms may have in generating innovation. A popular notion is that startup companies are able to attract employees with “fire in the belly,” allowing them to be more productive. Yet research has paid little attention to the motives and incentives of startup employees. This paper compares startup employees’ pecuniary and no...

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...

Experiments in NSTX have now demonstrated the coupling of toroidal plasmas produced by the technique of Coaxial Helicity Injection (CHI) to inductive sustainment and ramp-up of the toroidal plasma current. In these discharges, the central Ohmic transformer was used to apply an inductive loop voltage to discharges with a toroidal current of about 100 kA created by CHI. The coupled discharges hav...

A pacemaker is a small battery operated device that helps the heart to beat in a regular rhythm. It contains a powerful battery, electronic circuits, and computer memory that jointly generate electronic signals. One of the main problems about pacemakers is their batteries. Since the capacity of the batteries is limited, it limits the pacemakers lifetime. The other method to power up the implant...

Startup of distillation columns is one of the most difficult operations of chemical processes. Since it often lasts a period of time, leads to off-products and costs much energy, optimization of startup operating policies for distillation columns is of great interest in process industry. Most previous studies on column startup have been restricted to theoretical investigations such as modeling,...

Consider a video consisting of a sequence of fixedsize pages to be transmitted over c broadcast channels such that a page fits in a slot of a channel. In Shifted Harmonic Windows scheduling, page i must be scheduled at least once in any consecutive i+m−1 slots for some integer m ≥ 1, to ensure continuous display of successive pages by the viewer, starting at the m slot boundary after tuning in....
