As a process, software design is the software engineering life cycle activity in which software requirements are analyzed in order to produce a description of the software’s internal structure that will serve as the basis for its construction. A software design (as the result) describes the software architecture-that is, how software is decomposed and organized into components-and the interfaces between those components.

In the report they have explained breakdown of topics of process of software design.

There are many specific techniques involved in each of the four major sets of activities called POMA (Planning, Organizing, Monitoring, and Adjusting) phases. Some require extremely deep technical knowledge and others demand great social skills, in this section, we will focus on four commonly needed project management skills: project effort estimation, work breakdown structure, project status tracking with earned value and development measuring & metrics The first two of them are techniques needed in the planning and organizing phases, and the third is needed in the monitoring phase. The fourth is needed for part of planning and for monitoring.

In the report they have explained some techniques for estimating software project management

Software project management encompasses the knowledge, techniques and tools necessary to manage the development of software products. Software project management remains different from project management in other more established fields for a number of reasons. Software is “brain product” only, unconstrained by the laws of physics or by the limits of manufacturing processes. In the report discusses topics that managers need to create a plan for software development using effective estimation of size and to execute the plan with attention to productivity and quality.

The region of Varna proved to be a driest in terms of precipitation in this country. Trend test applied to climate datasets reviled a significant increase for seasonal reference evapotranspiration ETo during 1970-2004. Detected climate variability&droughts create uncertainties for maize irrigation scheduling and harvested yield. To cope with them, simulations have been performed for past (1951- 1984) and present (1951-2004) weather conditions using the validated water balance WinISAREG simulation model for two maize hybrids of different sensitivity to water stress grown on a Haplic Chernozem soil of medium water holding capacity. The study compares three irrigation scheduling alternatives built in agreement with past studies to develop environmentally sound/water saving irrigation technologies that consist of refilling the soil reservoir by adopting a management-allowed depletion fraction (MAD): (1) MAD=0.50; (2) MAD=0.33; (3) MAD=0.50 but partially refilling the soil reservoir. Simulations relative to the very high irrigation demand year of the current weather show that when aiming at maximum yield all three scheduling alternatives require the same irrigation depths ID=360mm that is 60 mm higher than conventional advised in the region. In the average demand years of past and current weather, Alternative 1 requires the same ID=270mm while a smaller ID=240mm is simulated with both alternatives 2 and 3 due to the fact that available soil water ASW is presently depleted to the optimum yield threshold OYT at harvest.
