To maximize the velocity of business value delivery, Alistair Cockburn talks of having a process that is “barely sufficient.” At Landmark Graphics we developed some guidelines as to what "barely sufficient" means for our various software projects. We examined over 60 projects and observed two primary attributes that influenced the type of process used: complexity and uncertainty. We provide a s...

As a result of current resource provisioning schemes in Internet services, servers end up less than 50% utilized almost all the time. At this level of utilization, the servers’ energy efficiency is less than half their efficiency at peak utilization. A solution to this problem could be consolidating workloads into fewer servers and turning others off. However, services typically resist doing so...

PURPOSE To study healing of retinal laser lesions in patients undergoing PRP using SD-OCT. METHODS Moderate, light and barely visible retinal burns were produced in patients with proliferative diabetic retinopathy scheduled for PRP using 100-, 20- and 10-ms pulses of 532-nm laser, with retinal spot sizes of 100, 200 and 400 μm. Lesions were measured with OCT at 1 hr, 1 week, 1, 2, 4, 6, 9 and...

in order to study of barely and wheat cultivars tolerance to metribuzin, a factorial experiment was conducted as a completely randomized design, with three replications in greenhouse of agricultural research at ferdowsi university of mashhad. treatments included wheat cultivars (backcross roshan, cross arvand, bahar, sepahan, gascosion, sayonez, bam garmsiry, garmsiri, ghods, pishtaz, chamran a...

the study was conducted to evaluate the effect of seed priming on root growth of two barley cultivars (hordeum vulgare l.) under salinity stress was performed in phytogel. the treatments included two cultivars of barely (yusuf and maquie), levels of seed priming (control, hydro-priming and priming with 4.35 g l-1 of urea) and four levels of nacl salinity stress (0, 0.2, 0.3 m). the experiment w...

in this paper the trade restrictiveness of agricultural policies in iran was measured by the triindex for the nine major agricultural products including wheat, rice, barely, maize, soybean,meat (beef meat), soybean oil, sugar and banana over the period 1981 to 2007. the main resultsindicate that there is no trend in above index and high volatility especially in 2006 and 2007years due to conside...
