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...

In order to further improve the operation level of provincial grid direct thermal power units, optimize data quality unit system, diagnose and analyze comprehensively evaluate regulation ability from aspects heating capacity, minimum startup mode whole plant, load capacity state, so as provide support for accurate scheduling unit.

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...

Second, the exchanger must withstand the service conditions of the plant environment. This includes the mechanical stresses of installation, startup, shutdown, normal operation, emergencies, and maintenance, and the thermal stresses induced by the temperature differences. It must also resist corrosion by the process and service streams (as well as by the environment); this is usually mainly a m...

In Denmark a considerable number of houses are connected to a district heating system. In a district heating system several production units may exist, and for the considered district heating system this is indeed the case. The production cost varies from production unit to production unit – the cheapest is often a waste incinerator plant. The varying consumption of heat means that some units n...

Typical management strategies proven to work in already established businesses do not work as expected in startups. Startups do not yet have a business model and product that they could focus on, but are still looking for a working business model. Lean Startup is a method for startup management that focuses on quick iteration and on fast learning to find an iterable business model. As a method,...

This paper presents a realization for the reliable and fast startup of distributed systems written in Erlang. The traditional startup provided by the Erlang/OTP library is sequential, parallelization usually requires unsafe and ad-hoc solutions. The proposed method calls only for slight modifications in the Erlang/OTP stdlib by applying a system dependency graph. It makes the startup safe, quic...

Kuosheng nuclear power plant (NPP) is a BWR/6 type NPP and located on the northern coast of Taiwan. First, Kuosheng NPP TRACE model were developed in this research. In order to assess the system response of Kuosheng NPP TRACE model, startup tests data were used to evaluate Kuosheng NPP TRACE model. Second, the overpressurization transient analysis of Kuosheng NPP TRACE model was performed. Besi...
