Since the first publication of this chapter in the previous edition of the Handbook, some changes have occurred in the theoretical landscape. Cognitive psychology has moved further away from its roots in information processing toward a stance that emphasizes individual and group construction of knowledge.

In this chapter we will be studying how to get the schematic into stick diagrams or layouts. MOS circuits are formed on four basic layers:
N-diffusion
P-diffusion
Polysilicon
Metal These layers are isolated by one another by thick or thin silicon dioxide insulating layers. Thin oxide mask region includes n-diffusion / p-diffusion and transistor channel.
Stick diagrams: Stick diagrams may be used to convey layer information through the use of a color code. For example: n-diffusion --green poly -- red blue -- metal yellow --implant black --contact areas

After completeing this chapter, the student is expected to know the following. • Know that cells as the basic units of life. • Understand that homeostasis is essential for cell survival, disruption in homeostasis can lead to illness and death, homeostatic control systems include closed and open loop systems • Know the negative and positive feedback mechanisms • Know the 3 levels of physiological regulations: intracellular, local (intrinsic) and extrinsic • Know the neural and endocrine reflexes control many events such as: somatic, autonomic, endocrine reflexes • Know most cells are subdivided into plasma membrane, nucleus and cytoplasm. • Know the functions of the ER, Golgi complex, lysosomes, peroxisomes, mitochondria, cytosol, cytoskeleton, plasma membrane is a fluid bilayer embedded with proteins, membrane proteins, the extra cellular matrix .

In this chapter, I will discuss mixed languages, and more generally language mixing, from the perspective of an evolutionary framework for understanding language change, described in Croft (2000). The focus of the analysis in this chapter is in relating the phenomenon of language mixing to the social processes which give rise to language change. In particular, I will examine the role of the concept of ACTS OF IDENTITY (LePage & Tabouret-Keller 1985) as a— perhaps the—major force in determining an individual’s choice of linguistic forms to use in particular social situations. This analysis is not crucially dependent on the evolutionary framework; however, the evolutionary framework offers a coherent, integrated model in which to describe and analyze these phenomena.

In this chapter we study a method for ﬁnding locations of system poles.
The method is presented for a very general set-up, namely for the case
when the closed-loop system poles are functions of an unknown parameter.
In most cases the parameter of interest is the system static gain
satisfying . However, any other unknown and variable
system parameter affecting pole locations can be used instead of .
The method is known as the root locus technique for solving polynomial
equations with constant or variable parameters. It was originally presented
in Ewans (1948, 1950).

In this chapter, the analysis methods learned in Chapters 16 and 17 are extended to the coverage of circuits with combinations of resistive, inductive, and capacitive elements. Series and parallel RZC circuits, plus series-parallel combinations, are studied. Circuits with both inductance and capacitance can exhibit the property of resonance, which is important in many types of applications. Resonance is the basis for frequency selectivity in communication systems. For example, the ability of a radio or television receiver to select a certain frequency that is transmitted by a particular station and, at the same time, to eliminate frequencies from other stations is based on the principle of resonance. The conditions in RIC circuits that produce resonance and the characteristics of resonant circuits are covered in this chapter.

In this introductory chapter, we shall start by reviewing the various modes of structural failure and highlight the importance of fracture induced failure and contrast it with the limited coverage given to fracture mechanics in Engineering Education. In the next section we will discuss some examples of well known failures/accidents attributed to cracking. Then, using a simple example we shall compare the failure load predicted from linear elastic fracture mechanics with the one predicted by “classical” strength of materials. The next section will provide a brief panoramic overview of the major developments in fracture mechanics. Finally, the chapter will conclude with an outline of the lecture notes.

In this chapter the basic concepts of curves and surfaces are introduced, and examples are given. These concepts will be described as subsets of R2 or R3 with a given parametrization, but also as subsets deﬁned by equations. The connection from equations to parametrizations is drawn by means of the implicit function theorems (Theorems 1.5, 1.6 and 1.7).
1.1 Curves It is well known from elementary geometry that a line in R2 or R3 can be described by means of a parametrization t 7→ p + tq where q 6= 0 and p are ﬁxed vectors, and the parameter t runs over the real numbers. Likewise, a circle in R2 (say with center 0) can be parametrized by t 7→ (rcost,rsint) where t ∈ R. The common nature of these examples is expressed in the following deﬁnition.
