Pannello divisorio

Un pannello divisorio è una struttura utilizzata in edilizia e nellarredamento per dividere spazi interni o esterni. Sovente è autoportante e - a differenza del tramezzo - facilmente amovibile. Può essere dotato di ruote e/o binari per movimentarlo. I pannelli divisori possono essere singoli o collegati fra di loro con cerniere o giunti. Pannelli divisori collegati per mezzo di cerniere possono essere definiti separé o paravento. I pannelli divisori trovano applicazione in numerosi ambiti dove è necessario provvedere ad una rapida riorganizzazione dello spazio: ad esempio in edifici industriali, uffici, sale riunioni, esposizioni, show-room e sale congressi. Sono qui elencate alcune tipologie di pannelli divisori: Divisori da tavolo, di piccolo formato, usati direttamente su tavoli o scrivanie, normalmente fonoassorbenti; Ancorati, fissati alla parete a unestremità e liberi dallaltra, generalmente a soffietto; Espositivi, utilizzati in uffici, mostre e vetrine. Generici per interni, in vari materiali ed eventualmente dotati di ruote; Fonoassorbenti, adatti ad esempio negli uffici schermi divisori; A soffietto, che possono essere richiusi senza occupare spazio; Industriali, di dimensioni anche considerevoli, utilizzati nei magazzini; I materiali impiegati sono i più differenti: i pannelli comuni, per utilizzi generici, sono solitamente in materiale plastico, ad esempio polistirene o policarbonato. Anche lalluminio e la tela trovano largo impiego. Per pannelli più elaborati e costosi possono essere utilizzati dal legno al ferro battuto, fino al vetro, al feltro o alle più svariate tappezzerie. Lo stesso discorso vale per le finiture, che possono essere nascoste o a vista e dei più svariati materiali, generalmente in alluminio nei pannelli divisori generici.

Divisore

Nella matematica, un intero b {\displaystyle b} è un divisore di un intero a {\displaystyle a} se esiste un intero c {\displaystyle c} tale che a = b ⋅ c {\displaystyle a=b\cdot c}. Ad esempio, 7 è un divisore di 42 in quanto 42 = 7 ⋅ 6 {\displaystyle 42=7\cdot 6}. Si dice anche che 7 divide 42, o che 42 è divisibile per 7 o che 42 è un multiplo di 7, e si scrive 7 ∣ 42 {\displaystyle 7\mid 42}. I divisori possono essere sia positivi che negativi. I divisori positivi di 42 sono {1, 2, 3, 6, 7, 14, 21, 42}. Casi particolari: 1 e -1 dividono qualunque intero, ed ogni intero è un divisore di 0. I numeri divisibili per 2 si chiamano pari, mentre quelli che non lo sono si chiamano dispari. Il nome è legato al fatto che lintero non nullo b {\displaystyle b} divide lintero a {\displaystyle a} se e solo se nella divisione con resto di a {\displaystyle a} per b {\displaystyle b} il resto è zero.

Tavola dei divisori

La tavola seguente elenca tutti i divisori dei numeri da 1 a 1000. Un divisore di un numero intero n è un numero intero m tale per cui si possa scrivere n = m × q cioè la divisione di n per m non ha resto: quindi la divisione può essere scritta come n / m che è di nuovo un numero intero il quale è necessariamente anche un divisore di n. Per esempio, 3 è un divisore di 21, poiché 21/3 = 7 e 7 appartiene ai numeri interi quindi 7 è anchesso un divisore di 21. Se m è un divisore di n così allora lo è − m. La tavola seguente cita solo i divisori positivi.

Grande Catena Divisoria

La Grande Catena Divisoria, è la più grande catena montuosa australiana, la quarta più lunga del mondo. Si estende per più di 3.500 km, con una larghezza che varia da circa 160 a più di 300 chilometri, da Dauan Island fino allestremità nordorientale del Queensland, percorrendo lintera costa orientale attraverso il Nuovo Galles del Sud, poi nel Victoria e svoltando ad ovest, prima di perdersi completamente nella pianura centrale nel Victoria occidentale. La grande differenza tra i bassopiani costieri e gli altopiani orientali ha influenzato il clima australiano, principalmente dovuto a precipitazioni orografiche, e queste aree di maggior rilievo si sono rivelate un paesaggio impressionante di burroni.

Checkout divider

A checkout divider is a small sign or bar meant for placement between items on a conveyor belt at a checkout in a supermarket or other retail store. Its purpose is to separate one customers items from another customers. Checkout dividers can usually be found next to the conveyor belt on the side where the cashier is sitting. Most checkout dividers display the name of the store or some sort of advertising. Checkout dividers have been the subject of numerous internet debates, mainly regarding the use of checkout dividers.

Room divider

A room divider is a screen or piece of furniture placed in a way that divides a room into separate areas. Room dividers are used by interior designers and architects as means to divide space into separate distinct areas. There are a number of different types of room dividers such as cubicle partitions, pipe and drape screens, shoji screens, and walls. Room dividers can be made from many materials, including wood, fabric, plexiglass, framed cotton canvas, pleated fabric or mirrors. Plants, shelves or railings might also be used as dividers. Portable room dividers have folded wall panels supported on wheels.

Word divider

In punctuation, a word divider is a glyph that separates written words. In languages which use the Latin, Cyrillic, and Arabic alphabets, as well as other scripts of Europe and West Asia, the word divider is a blank space, or whitespace, a convention which is spreading, along with other aspects of European punctuation, to Asia and Africa. However, many languages of East Asia are written without word separation. In character encoding, word segmentation depends on which characters are defined as word dividers.

Kelvin–Varley divider

The Kelvin-Varley voltage divider, named after its inventors William Thomson, 1st Baron Kelvin and Cromwell Fleetwood Varley, is an electronic circuit used to divide voltages, i.e. to generate an output voltage as a precision ratio of an input voltage, with several decades of resolution. In effect, the Kelvin–Varley divider is an electromechanical precision digital-to-analog converter. The circuit is used for precision voltage measurements in calibration and metrology laboratories. It can achieve resolution, accuracy and linearity of 0.1 ppm 1 in 10 million.

Current divider

In electronics, a current divider is a simple linear circuit that produces an output current that is a fraction of its input current. Current division refers to the splitting of current between the branches of the divider. The currents in the various branches of such a circuit will always divide in such a way as to minimize the total energy expended. The formula describing a current divider is similar in form to that for the voltage divider. However, the ratio describing current division places the impedance of the considered branches in the denominator, unlike voltage division where the considered impedance is in the numerator. This is because in current dividers, total energy expended is minimized, resulting in currents that go through paths of least impedance, hence the inverse relationship with impedance. Comparatively, voltage divider is used to satisfy Kirchhoffs Voltage Law KVL. The voltage around a loop must sum up to zero, so the voltage drops must be divided evenly in a direct relationship with the impedance. To be specific, if two or more impedances are in parallel, the current that enters the combination will be split between them in inverse proportion to their impedances according to Ohms law. It also follows that if the impedances have the same value the current is split equally.

Voltage divider

In electronics, a voltage divider is a passive linear circuit that produces an output voltage that is a fraction of its input voltage. Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them. Resistor voltage dividers are commonly used to create reference voltages, or to reduce the magnitude of a voltage so it can be measured, and may also be used as signal attenuators at low frequencies. For direct current and relatively low frequencies, a voltage divider may be sufficiently accurate if made only of resistors; where frequency response over a wide range is required such as in an oscilloscope probe, a voltage divider may have capacitive elements added to compensate load capacitance. In electric power transmission, a capacitive voltage divider is used for measurement of high voltage.

Frequency divider

A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, f i n {\displaystyle f_{in}}, and generates an output signal of a frequency: f o u t = f i n {\displaystyle f_{out}={\frac {f_{in}}{n}}} where n {\displaystyle n} is an integer. Phase-locked loop frequency synthesizers make use of frequency dividers to generate a frequency that is a multiple of a reference frequency. Frequency dividers can be implemented for both analog and digital applications.

Lone divider

The lone divider procedure is a procedure for proportional cake-cutting. It involves a heterogenous and divisible resource, such as a birthday cake, and n partners with different preferences over different parts of the cake. It allows the n people to divide the cake among them such that each person receives a piece with a value of at least 1/ n of the total value according to his own subjective valuation. The procedure was developed by Hugo Steinhaus for n =3 people. It was later extended by Harold W. Kuhn to n > 3, using the Frobenius-Konig theorem. A description of the cases n =3, n =4 appears in and the general case is described in.

Memory divider

A memory divider is a ratio which is used to determine the operating clock frequency of computer memory in accordance with front side bus frequency, if the memory system is dependent on FSB clock speed. Along with memory latency timings, memory dividers are extensively used in overclocking memory subsystems to find stable, working memory states at higher FSB frequencies. The ratio between DRAM and FSB is commonly referred to as "DRAM:FSB ratio". Memory dividers are only applicable to those chipsets in which memory speed is dependent on FSB speeds. Certain chipsets like nVidia 680i have separate memory and FSB lanes due to which memory clock and FSB clock are asynchronous and memory dividers are not used there. Setting memory speeds and overclocking memory systems in such chipsets are different issues which do not use memory dividers. This article is only applicable to those chipsets in which the memory clock is dependent on FSB clock.

Wilkinson power divider

In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports. The Wilkinson design can also be used as a power combiner because it is made up of passive components and hence reciprocal. First published by Ernest J. Wilkinson in 1960, this circuit finds wide use in radio frequency communication systems utilizing multiple channels since the high degree of isolation between the output ports prevents crosstalk between the individual channels. It uses quarter wave transformers, which can be easily fabricated as quarter wave lines on printed circuit boards. It is also possible to use other forms of transmission line e.g. coaxial cable or lumped circuit elements inductors and capacitors.
