Which design techniques do I have at my disposal & how do I know when to apply them? PART 2 of 2

There are a great number of design methods & it is important to choose those that are best suited to your particular circumstances & objectives.

In this class we look at some of those methods & talk about the criteria to take into account for their use.

• . ¿Qué técnicas de diseño tengo a mi disposición y cómo se cuando aplicarlas? Parte 1     Existen multitud de métodos de diseño y es importante elegir el que mejor se ajuste a las circunstancias y objetivos. En está clase veremos algunos de esos métodos y hablaremos de los criterios para utilizarlos.
• Approximate and true golden spirals: the green spiral is made from quarter-circles tangent to the interior of each square, while the red spiral is a golden spiral, a special type of logarithmic spiral . Overlapping portions appear yellow . The length of the side of a larger square to the next smaller square is in the golden ratio .

• A Systems Engineering solution begins by accurately identifying the needs, goals, and objectives of your project. Some definitions &amp;quot;An interdisciplinary approach and means to enable the realization of successful systems&amp;quot; [6] — INCOSE handbook, 2004. &amp;quot;System engineering is a robust approach to the design, creation, and operation of systems. In simple terms, the approach consists of identification and quantification of system goals, creation of alternative system design concepts, performance of design trades, selection and implementation of the best design, verification that the design is properly built and integrated, and post-implementation assessment of how well the system meets (or met) the goals.&amp;quot; [7] — NASA Systems Engineering Handbook, 1995. &amp;quot;The Art and Science of creating effective systems, using whole system, whole life principles&amp;quot; OR &amp;quot;The Art and Science of creating optimal solution systems to complex issues and problems&amp;quot; [8] — Derek Hitchins, Prof. of Systems Engineering, former president of INCOSE (UK), 2007. &amp;quot;The concept from the engineering standpoint is the evolution of the engineering scientist, i.e., the scientific generalist who maintains a broad outlook. The method is that of the team approach. On large-scale-system problems, teams of scientists and engineers, generalists as well as specialists, exert their joint efforts to find a solution and physically realize it...The technique has been variously called the systems approach or the team development method.&amp;quot; [9] — Harry H. Goode &amp; Robert E. Machol, 1957. &amp;quot;The systems engineering method recognizes each system is an integrated whole even though composed of diverse, specialized structures and sub-functions. It further recognizes that any system has a number of objectives and that the balance between them may differ widely from system to system. The methods seek to optimize the overall system functions according to the weighted objectives and to achieve maximum compatibility of its parts.&amp;quot; [10] — Systems Engineering Tools by Harold Chestnut, 1965.

39. 80. Guilds in Design A harmonious assembly of species around a central element (plant or animal) This assembly acts to assist health, aid our work in management, or buffer adverse environmental effects
40. 81. Controlling pests, disease, hazards Save - energy accumulator Mimic the behavior and benefit of natural cycles-processes-patterns cause mutual benefits, create balance Yield without extra inputs Create a healthy habitat Encourage natural succession USES BENEFITS SYNERGIES
41. 82. Crop Associations One plant attract other plant's predators Help with pest control Provide Nutrients Creating open soil surface conditions or providing mulch Reduce roots competition Provide physical shelter from Frost, sunburn, wind... To Facilitate Harvest
42. 83. Some Associations GARLIC : prevents parasites and fungal diseases in all plants - don't use with legumes and cabbage. GARLIC, ONION or LEEK with CARROT: against the flies of both CORN with BEANS and CUCURBITS (not squash) against aphids. The beans can climb the maize & cucurbits grow below to keep weeds at bay. Although that may attract mildew. CARROTS WITH PEAS : The secretion of the roots of the first promotes the growth of the latter. CABBAGE with TOMATOES : Tomatoes mask the smell of cabbage and vice versa, preventing pests of both. Also the shape of cabbage can blend in with the tomatoes.
43. 84. POTATOES benefit from a previous BEANS rotation to prevent fungal diseases. Comfrey also does very well around. SALAD with CELERY : lettuce in summer will benefit from the shadows & their roots do not compete for nutrients. CABBAGES & other BRASSICA with CLOVER : the latter repels cabbage butterfly BORAGE goes well with TOMATOES, ZUCCHINI and STRAWBERRY BASIL repels insects and goes well with TOMATOES and PEPPERS
44. 86. Some Antagonists GARLIC, ONIONS, LEEKS go very poorly with LEGUMES because the first interfere with the fixing of nitrogen of the latter SUNFLOWER - Reduce the production of nearby plants, but also attract pest predators + changes the shape of the garden, misleading pests As a general rule do not plant species of the same family together, as they are affected by the same pests.
45. 88. Physical Complementarity • Some plants like sunshine and other a bit of shadow in Summer. Lettuce & carrots can be planted with some plants that give them some shadow. • There are plants with deep roots and others with more superficial ones, these can be combined. Eg. TOMATOES & LETTUCES. • Plants with different maturation times can also be combined. Eg. CARROTS AND RADISHES. • Some insects recognize plants by their silhouette or odor and these can be camouflaged by other plants
