Harvesting energy from the environment by using a thermoelectric generator (TEG) or photovoltaic cells provides a solution for battery-free sensor networks or electronic healthcare systems. In these systems, the harvested energy is supplied at a very low voltages, requiring a low-startup-voltage power circuit for kick-start from low voltage. A previous sub-100mV-startup-voltage boost converter ...

Due to the context-sensitive nature of entrepreneurial orientation (EO), it is imperative to in-depth explore the EO-performance mechanism in China at its critical, specific stage of economic reform. Under the context of "reverse internationalization" by Chinese global startup original equipment manufacturers (OEMs), this paper aims to manifest the unique links and complicated interrelationship...

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,...

Performance-critical components of virtual machines are often implemented in assembly language. Traditionally, this code is compiled with an assembler and linked statically with the rest of the system. Generating this code at startup time has significant engineering advantages over the conventional approach: The generated machine code is much safer, easier to maintain, and has better performanc...

A microbial electrolysis cell (MEC) is a bioelectrochemical system that can produce hydrogen from acetate at high hydrogen recoveries, but the composition and structure of the microbial communities in this system have not been extensively studied. We used a high throughput metagenomics technology (GeoChip) to examine the microbial community functional structure in MECs initially operated under ...

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...

Many works have reported simulated performance benefits of stream reuse techniques such as chaining, batching, and patching to the scalability of VoD systems. However, the relative contribution of such techniques have been rarely evaluated in practical implementations of scalable VoD servers. In this work, we investigate the efficiency of representative stream reuse techniques on the GloVE syst...
