RIOT: An Open Source Operating System for Low-End Embedded Devices in the IoT
IEEE Internet of Things Journal, 2018As the Internet of Things (IoT) emerges, compact operating systems (OSs) are required on low-end devices to ease development and portability of IoT applications. RIOT is a prominent free and open source OS in this space.

Publisher Summary Systems programs control the operation of the computer. Applications programs instruct the computer how to handle an organization's information-processing needs. Systems programmers require an understanding of the internal operation of computer hardware.

An operation inducing system is a collection [S,(G,\(\circ),f,h,\Gamma,\cdot]\) composed of a nonempty set S, a groupoid (G,\(\circ)\), functions f:S\(\to G\) and h:S\(\to S\), a subset \(\Gamma\) of G such that f(S)\(\subseteq \Gamma\) and a function ``\(\cdot ''\) from \(\Gamma\times S\) into S. The groupoid (S,*) defined by \(x*y=f(x)\cdot h(y)\) is

Protection in operating systems
Communications of the ACM, 1976A model of protection mechanisms in computing systems is presented and its appropriateness is argued. The “safety” problem for protection systems under this model is to determine in a given situation whether a subject can acquire a particular right to an object. In restricted cases, it can be shown that this problem is decidable, i.e.

At this point in this work, it is useful to examine the record of the European Monetary System. However, this record should be placed in its proper context. This implies that we are not examining an EMU — but an EMS — which is a kind of de-facto monetary union.

The gentlemen who have preceded me here today have all represented what might be titled the "heroes" of the computer world; the business men of vision who can foresee the coming revolution in business data processing which the modern computer portends, the system engineer who molds this tool into usable and workable forms, and the computer designer who

A System of Operator Equations
Canadian Mathematical Bulletin, 1987AbstractLet be a separable Hilbert space, the algebra of all bounded operators on and Ai, Bi, ∊ , i = 1,. . . , r. It is shown that if no nontrivial linear combination of the operators Ai, is compact, then there exist X, Y ∊ such that X Ai, Y = Bi, for all i.

Only the very simplest kind of microcomputer is without any form of backing store, that is, discs or cassettes. Any system which is as simple as this has all the programs which make it work stored in ROMs. Such programs are called firmware and they can only be changed by replacing one ROM with another. Anything in the way of instructions or data stored
