Managing Constant Flow of Requirements: Screening Challenges in Very Large-Scale Requirements Engineering

This article contains a systematic literature review of requirements engineering for software systems. The literature published within last 5 years was included into the review. A research question was defined as requirements development process of large scale software system (with thousands of requirements) and an interaction problem during this process (communication, coordination and control). The problem is caused by the fact that large-scale software system requirements process is a cross-disciplinary task and it involves multiple parties — stakeholders, domain experts, and suppliers with own goals and constrains, and thus, the interaction between them seriously slows down the overall requirements development process than writing the requirements specification itself. The research papers were classified by several research directions: Natural Language Processing for Requirements Engineering (NLP4RE), Requirement Prioritization, Requirements Traceability, Quality of Software Requirements, Non-functional Requirements and Requirements Elicitation. Motivation and intensity of each direction was described. Each direction was structured and represented with the key references. A contribution of each research direction into the research question was analyzed and summarized including potential further steps. It was identified that some researchers had met a part of the described problem in different forms during their researches. At the end, other researches were described additionally in a short overview. To approach the research question further potential direction was described.

Do So

The singular ‘farm’ is increasingly a place of ever-greater multitudes, a deceptive and porous whole that is, in so many ways, very much less than the sum of its constituent parts. What might stand as a seemingly fixed entity or unit is, in reality, a constant flow and passage of multiple life ( zoe) and individual lives ( bios). To borrow from Heraclitus’ attributed aphorism, you can never really go into the same farm twice. Yet farms are, arguably, amongst the most defining sites of contemporary human/animal relations. The vast majority of the 24 or so billion terrestrial farm animals that are kept and grown for human and other consumption at any one time do so on farms, with an increasing proportion of them on large scale, industrial farm units. Here is where kingdoms most emphatically meet, collide, intertwine, entangle, respond: the sovereign and the beast, the beast and the sovereign. Three questions: who meets who on the farm, what do they meet, and how does such meeting matter?

Gear Pumps

In this paper, an asymmetric double circular arc gear which is suitable for large-scale high-pressure gear pumps is introduced. While demonstrated its superiority, the displacement formula of the double circular arc gear pump is derived and the gear parameters are identified. The asymmetric double circular arc gear can meet the needs of large displacement and high pressure. There are advantages such as constant flow, no pulse, and no topping, which make this kind of gear has a bright future.
