Startup sebagai solusi dari berbagai permasalahan di Indonesia kini mulai mendapatkan sorotan. Tetapi sebagian banyak perusahaan yang mengembangkan startup hanya sedikit mampu bertahan dan berhasil menghasilkan profit. Menurut Forbes, angka kegagalan dalam bisnis mencapai 90%. Oleh karena itu penelitian ini dilakukan dengan tujuan untuk mengetahui faktor atau hambatan sebuah dapat berkembang. P...

Transmission control protocol (TCP) has undergone several transformations. Several proposals have been put forward to change the mechanisms of TCP congestion control to improve its performance. A line of research tends to reduce speed in the face of congestion thereby penalizing itself. In this group are the window based congestion control algorithms that use the size of congestion window to de...

Technology startups are important regional economic engines that recognized as drivers of sustainable growth. Understanding the factors influence their success is interest both to scientific community and practitioners. However, there currently no consensus in literature on how define a technology startup. Startup has multiple dimensions different theoretical approaches empirical contexts. Ther...

As part of an ongoing effort to apply the tools of systems engineering to the problems of modeling, controlling, and operating kraft recovery systems, a rather long historical record of chemical makeups to this process has been scrutinized. The data describe the pulp production, makeup of salt cake, and makeup of caustic for a single large pulp mill on a monthly basis over almost nine years fro...

The Orange County Water District (OCWD) in California has been operating a Groundwater Replenishment System (GWRS, Figure 1) since 2008. The GWRS treats secondary effluent from a wastewater treatment plant (WWTP) for distribution to reinjection wells, spreading basins, and industrial users. Upstream of the reverse osmosis system (RO), the secondary effluent goes through a microfiltration proces...

In order to achieve high power generation efficiency, facility compactness, safety, and coexistence with fuel tritium in the 3 G Wth class FFHR(Force Free Helical Reactor) plant, optimization, performance operation scenario of system plant model using axial flow type uniaxial supercritical CO2 gas turbine were examined. As a result, following conclusions obtained. (1) The most efficient compact...

The thermal-power-plant condenser tubes, conducting cooling seawater, experienced frequent leakages, prompting the hereby presented failure analysis. Visual inspection of corroded/ruptured tube segments revealed that localized corrosion may be linked to seawater sediments and thick layers products at water side. Sediments were found along bottom adjacent point contact between baffle plates exte...

This study investigates a random N-policy Geo/G/1 queue with startup and closedown times. N is newly determined every time a new cycle begins. When random N customers are accumulated, the server is immediately turned on but is temporarily unavailable to the waiting customers. It needs a startup time before starting providing service. After all customers in the system are served exhaustively, th...

In this paper a new method for the detection of broken rotor bars in induction machines is introduced. The startup transient current of an induction machine is used as the medium for diagnoses. The fundamental component is extracted using an algorithm that predicts the instantaneous amplitude and frequency during startup. The residual current is then analyzed using wavelets and a comparison is ...
