Entities in software development

Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through the final manifestation, typically in a planned and structured process often overlapping with software engineering. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations. The sources of ideas for software products are plentiful. These ideas can come from market research including the demographics of potential new customers, existing customers, sales prospects who rejected the product, other internal software development staff, or a creative third party. Ideas for software products are usually first evaluated by marketing personnel for economic feasibility, fit with existing channels of distribution, possible effects on existing product lines, required features, and fit with the company's marketing objectives. In the marketing evaluation phase, the cost and time assumptions become evaluated. A decision is reached early in the first phase as to whether, based on the more detailed information generated by the marketing and development staff, the project should be pursued further. In the book "Great Software Debates", Alan M. Davis states in the chapter "Requirements", sub-chapter "The Missing Piece of Software Development" Students of engineering learn engineering and are rarely exposed to finance or marketing. Students of marketing learn marketing and are rarely exposed to finance or engineering.

Force on a dipole

Consider a electric dipole formed by two charges u2005+u2005q and u2005−u2005q, separated by a distance d, in an non uniform electric field

\bf{E}(\bf{r})

. Show, from the potential energy E_(P), that the dipole is subject to a force

\bf{F}=(\bf{p}\cdot \nabla)\bf{E}

. Indication: Use the relation

\nabla\left(\frac{{\partial f}}{{\partial x_i}}\right)=\frac{{\partial}}{{\partial x_i}}\left(\nabla f\right)~.

The potential energy of a dipole in an electric field is:

Planar capacitor connected to a battery

A planar capacitor, whose plates are separated by l, is connected to a battery producing a difference of potential V₀, as indicated in the figure. A dipole constituted of two masses m of opposite charges u2005±u2005q and of length 2a is placed between the plates of the capacitor, tilted of a small angle θ with respect to the lines of electric field. What is the angular frequency of the oscillations of the dipole when we release it ? The moment of inertia of the dipole : Iu2004=u20042ma². The electric fiel

Metallic layer in a planar capacitor

The electrodes of a planar capacitor, of surface A and separated by a distance d, carry free chargesu2005±u2005Qu2004=u2004u2005±u2005σA. A metallic layer, uncharged and with thickness a, is inserted between the two electrodes, as in the figure. a) Determine the difference of potential and the capacity of the capacitor. Show that the capacity is equivalent to the one of two capacitors in series, for whom we will give the characteristics. b) Show that the capacity of the capacitor is not modified if the me

Coupled oscillator

Two material points, with identical mass m, are frictionlessly moving in a straight line, on a horizontal track (see diagram). They are attached together by a spring with constant K. Each material point is attached to a fixed point on the track by another spring, with constant k. The three springs have rest length l₀, and the fixed points are separated by a distance 3l₀.

Write each material point’s equations of motion.
Deduce the equations of motion of the center of mass and that system’s rela

Steering wheel and chassis

A horizontal steering wheel can turn around a vertical axis δ going through its center of mass G. That axis is secured to a chassis that can turn around another vertical axis Δ. Both axes are are separated by a distance d and we write O the point on axis Δ that’s a distance d from point G. The steering wheel has mass m and moment of inertia

I_{\rm v,\delta}

with respect to its principal axis δ. The chassis, on its own, has mass M and moment of inertia

I_{\rm c,\Delta}

with respect to its principal axis
