A new method has been developed for the detection of broken rotor bars fault in squirrel cage induction motor during startup regimes. The incipient detection of fault is made by using DWT analysis of FIR low pass filtered original startup transient current signal. The extracted particular characteristic evolution of the time-varying signal is used as a fault index. The method was tested using h...

Abstract How large is entrepreneurs’ personal importance to startups? We use the death of nearly 1,500 entrepreneurs as a source exogenous variation, and find sustained negative effects on growth profitability. For small startups, go mainly via firm survival, while for larger startups are growth. mean effect sales about 60%. The appear be driven by entrepreneur specialness rather than leadershi...

biofiltration of triethylamine (tea) vapor used as a catalyst in casting operations was evaluated in this study. the unit consisted of a 6-l three-stage biofilter containing a mixture of compost and wood chips (40:60 v/v) as the filter medium. seed microbial population from municipal activated sludge was acclimated for a period of three weeks prior to the actual experimental runs. in the startu...

U ovom radu, kao prvi korak, opisane su neke od najrelevantnijih teorija za pokretanje i analizu strartup projekata. Nakon teorijskog pregleda, analiziran je startup, koji u momentu pisanja rada procesu razvoja. Cilj ovog primeniti Lin Kanvas Model kreiranju preciznije vizije smera razvoja obrađenog startup projekta.

Multimedia data poses challenges for efficient storage and retrieval due to its large size and playback timing requirements. For applicat;ions that store very large volumes of multimedia data, hierarchical storage offers a scalable and economical alternative to store data on magnetic disks. In a hierarchical storage architecture data is stored on a tupe or optical disk based tertiary storage la...

Maintenance or repair of water mains may require the interruption of flow. Re-initiation of flow may present opportunities for the interaction of air and the accelerating water, resulting in undesirable pressure transients. This study focuses on air intrusion during flow startup in an initially filled horizontal pipeline supplied by a constant-head reservoir. Flow was initiated by opening the d...
